RESUMEN

BACKGROUND: In 2006, the World Health Organization (WHO) introduced new growth standards based on data derived globally from optimally nourished breastfed infants. The aim of this study was to assess the effects of implementing WHO growth standards on the growth patterns of Jordanian infants. In addition, it was to ascertain the necessity of establishing country-specific growth standards and charts tailored to Jordanian infants. MATERIALS AND METHODS: The data of 102,846 infants (50.1% boys, 49.9% girls) aged 0-24 months, from 115 primary healthcare centers across the country were retrieved from a National E-health Program. Weight and length measurements were analyzed, and age- and sex-specific z-scores were calculated relative to the WHO growth standards. Data was analyzed using SPSS version 26. Mann-Whitney U test was performed to determine significant differences between the measurements for boys and girls in terms of age, length, and weight. RESULTS: Jordanian infants exhibited significantly shorter length-for-age measurements than WHO standards with mean z-scores of -0.56 and -0.38, for boys and girls, respectively. Weight-for-age measurements showed a good fit and were comparable to the WHO growth standards for boys (mean z score = -0.05) and girls (mean z score = 0.04). Notably, Jordanian infants displayed higher weight-for-length measurements, with mean z-scores of 0.51 for boys and 0.47 for girls. CONCLUSION: The availability of Jordanian-specific growth standards will improve the accuracy of assessing infant growth and enhance the monitoring and evaluation of their health and development.

RESUMEN

AIM: To synthesize available evidence on the association between change in linear growth (height for age z score, HAZ) beyond the first two years of life with later child neurodevelopment outcomes in Low- and middle-income countries (LMICs). METHODS: We searched PubMed, Web of Science, and EMBASE for cohort studies on the association between change in HAZ after age two and neurodevelopment outcomes in middle or late childhood. Data extraction was done independently by two reviewers. RESULTS: A total of 21 studies, that included 64,562 children from 13 LMICs were identified. Each unit increase in change in HAZ above two years is associated with a + 0.01 increase (N = 8 studies, 27,393 children) in the cognitive scores at 3.5 to 12 years of age and a + 0.05-standard deviation (SD) increase (95% CI 0.02 to 0.08, N = 3 studies, 17,830 children) in the language score at 5 to 15 years of age. No significant association of change in HAZ with motor (standardized mean difference (SMD) 0.04; 95% CI: -0.10, 0.18, N = 1 study, 966 children) or socio-emotional scores (SMD 0.00; 95% CI: -0.02, 0.01, N = 4 studies, 14,616 participants) was observed. CONCLUSION: Changes in HAZ after the first two years of life appear to have a small or no association with child neurodevelopment outcomes in LMICs.

RESUMEN

Undernutrition is a major public health problem in developing countries. Around 40·2 % of children are stunted in Pakistan. This longitudinal study aimed to assess the effectiveness of locally produced ready-to-use supplementary foods in the prevention of stunting by detecting change in of children in intervention v. control arm against the 2006 WHO growth reference. A community-based non-randomised cluster-controlled trial was conducted from January 2018 to December 2020 in the district of Kurram, Khyber Pakhtunkhwa, Pakistan. A total of 80 clusters (each cluster comprising ≈ 250-300 households) were defined in the catchment population of twelve health facilities. Children aged 6-18 months were recruited n 1680. The intervention included a daily ration of 50 g - locally produced ready-to-use-supplementary food (Wawa-Mum). The main outcome of this study was a change in length for age z-score (LAZ) v. WHO growth standards. Comparison between the interventions was by t test and ANOVA. Cox proportional hazard models were used to assess the association between stunting occurrence and the utilisation of locally produced supplement. Out of the total 1680, fifty-one out of the total 1680, 51·1 out of the total 1680 and 51·1 % (n 859) were male. Mean age 13·9 months (sd + 859) were male. Mean age 13·9 months (sd + -4·4). At baseline, 36·9 % (n 618) were stunted. In the intervention group, mean LAZ score significantly increased from -1·13(2·2 sd) at baseline to -0·93(1·8 sd) at 6-month follow-up (P value 0·01) compared with the control group. The incidence rate of stunting in the intervention arm was 1·3 v. 3·4 per person year in the control arm. The control group had a significantly increased likelihood of stunting (Hazard Ratio (HR) 1·7, 95 % CI 1·46, 2·05, P value < 0·001) v. the intervention group. Locally produced ready-to-use supplementary food is an effective intervention for reducing stunting in children below 2 years of age. This can be provided as part of a malnutrition prevention package to overcome the alarming rates of stunting in Pakistan.

RESUMEN

To meet the 2030 goal to end all types of malnutrition, thoroughly investigating and addressing context-specific factors of undernutrition is crucial. Therefore, this study assessed the prevalence of undernutrition and associated factors among children aged 6-23 months in South-East Ethiopia. A community-based cross-sectional study was conducted on 580 randomly sampled mother-child pairs in February 2022. Socio-demographic, dietary intake, household food security (HFS), maternal knowledge and practices of child feeding, and the child's weight and height data were collected. A multivariable logistic regression analysis was done. The prevalence of stunted, wasted, and underweight children was 32⋅1, 7, and 9 %, respectively. Being male (AOR = 1⋅75), not using the growth monitoring and promotion (GMP) service (AOR = 1⋅50), household food insecurity (HFI) (AOR = 1⋅67), lack of improved water (AOR = 2⋅26), and bottle-feeding (AOR = 1⋅54) were significantly associated with stunting. Being male (AOR = 3⋅02), having low maternal knowledge on child-feeding practices (AOR = 3⋅89), not listening to the radio/television (AOR = 3⋅69), having a history of fever (AOR = 3⋅39), bottle-feeding (AOR = 3⋅58), and HFI (AOR = 3⋅77) were significantly predicted wasting. Being male (AOR = 3⋅44), not using GMP service (AOR = 2⋅00), having a history of fever (AOR = 4⋅24), lack of knowledge on optimal breastfeeding duration (AOR = 3⋅58), low maternal knowledge on child feeding (AOR = 2⋅21), HFI (AOR = 2⋅04), and lack of improved water (AOR = 3⋅00) showed significant association with underweight. In conclusion, stunting is alarmingly common while wasting and underweight are sub-optimal. Prevention of infectious disease, providing basic education for fathers, ensuring HFS; enhancing media access, maternal knowledge about IYCFP and improving water access; and GMP service utilisation are crucial to improve child nutrition.

RESUMEN

Introduction: Length for Age Z (LAZ) score determinants are complex and vary among different areas, but it is important for designing effective and efficient strategies to decrease stunting prevalence among children under 2 years. This study aimed to investigate the determinants of LAZ scores among children under 2 years in Central Java, Indonesia. Methods: This study was conducted on the 2021 Indonesian Nutritional Status Study (INSS) dataset, which was a cross-sectional survey. Data on 3,430 children aged 6-23 months from Central Java province were derived from the 2021 INSS data. After missing data elimination, 3,238 subjects were included in the analysis. Determinant factors included direct and indirect factors. Direct factors were the mother's age, birth weight Z score (BWZ), birth length Z score (BLZ), exclusively breastfed history, dietary diversity scores (DDS), empty calorie drink consumption, unhealthy snacks consumption, and infections. Indirect factors were early initiation of breastfeeding (EIBF) and posyandu (integrated health post) utilization. Underlying factors were socioeconomic status (SES) and the mother's education. Bivariate analyses and multiple linear regressions were conducted. A path analysis with a hypothesized model based on the UNICEF conceptual framework was also performed. Results: Stunting, wasting and underweight proportions among the subjects were 19.1%, 7.6% and 12.3%, respectively. The mean LAZ scores were -0.95 ± 1.22; the mother's age was 29.7 ± 5.95 years; BWZ was -0.47 ± 0.97; BLZ was -0.55 ± 1.05; and DDS was 4.45 ± 1.51. The infection proportion among the subjects was 28%. BWZ and BLZ were positively correlated to LAZ scores, with r = 0.267 (p < 0.01) and r = 0.260 (p < 0.01), respectively. The mother's age was negatively correlated to LAZ scores with r = -0.041 (p < 0.05). Maternal education was positively correlated to SES but had no direct effect on LAZ scores. LAZ score determinants of BLZ (p < 0.001) and SES (p < 0.001) showed positive direct associations with LAZ scores, but the mother's age (p = 0.039), exclusively breastfed history (p < 0.001), and empty calorie drinks consumption (p < 0.001) had negative associations with LAZ scores. Conclusion: To prevent stunting among children aged 6-23 months in Central Java, Indonesia, intervention programs to increase the nutritional status of women at child-bearing age and nutrition education on child feeding practices should be conducted more efficiently and effectively.

RESUMEN

Background: Isoniazid preventive therapy (IPT) initiation during pregnancy was associated with increased incidence of adverse pregnancy outcomes in the TB APPRISE trial. Effects of in utero IPT exposure on infant growth are unknown. Methods: This post-hoc analysis used data from the TB APPRISE trial, a multicentre, double-blind, placebo-controlled trial, which randomised women to 28-week IPT starting in pregnancy (pregnancy-IPT) or postpartum week 12 (postpartum-IPT) in eight countries with high tuberculosis prevalence. Participants were enrolled between August 2014 and April 2016. Based on modified intent-to-treat analyses, we analysed only live-born babies who had at least one follow-up after birth and compared time to infant growth faltering between arms to 12 weeks and 48 weeks postpartum in overall and sex-stratified multivariable Cox proportional hazards regression. Factors adjusted in the final models include sex of infant, mother's baseline BMI, age in years, ART regimen, viral load, CD4 count, education, and household food insecurity. Results: Among 898 HIV-exposed uninfected (HEU) infants, 447 (49.8%) were females. Infants in pregnancy-IPT had a 1.47-fold higher risk of becoming underweight by 12 weeks (aHR 1.47 [95% CI: 1.06, 2.03]) than infants in the postpartum-IPT; increased risk persisted to 48 weeks postpartum (aHR 1.34 [95% CI: 1.01, 1.78]). Maternal IPT timing was not associated with stunting or wasting. In sex-stratified analyses, male infants in the pregnancy-IPT arm experienced an increased risk of low birth weight (LBW) (aRR 2.04 [95% CI: 1.16, 3.68), preterm birth (aRR 1.81 [95% CI: 1.04, 3.21]) and becoming underweight by 12 weeks (aHR 2.02 [95% CI: 1.29, 3.18]) and 48 weeks (aHR 1.82 [95% CI: 1.23, 2.69]). Maternal IPT timing did not influence growth in female infants. Interpretation: Maternal IPT during pregnancy was associated with an increased risk of LBW, preterm birth, and becoming underweight among HEU infants, particularly male infants. These data add to prior TB APPRISE data, suggesting that IPT during pregnancy impacts infant growth, which could inform management, and warrants further examination of mechanisms. Funding: The TB APPRISE study Supported by the National Institutes of Health (NIH) (award numbers, UM1AI068632 [IMPAACT LOC], UM1AI068616 [IMPAACT SDMC], and UM1AI106716 [IMPAACT LC]) through the National Institute of Allergy and Infectious Diseases, with cofunding from the Eunice Kennedy Shriver National Institute of Child Health and Human Development (contract number, HHSN275201800001I) and the National Institute of Mental Health.

RESUMEN

Little is known about the relation between the women empowerment in agriculture index, and health and nutrition outcomes among under-five children in Ethiopia. The study's objective was to examine women's empowerment in agriculture and its association with the nutritional status of children (6-59 months) in rural, cash crop producing, and resource-limited settings of Ethiopia. A community-based cross-sectional study was conducted employing 422 households; having women of reproductive age group and children under-five. Stratified simple random sampling was used to identify households; a simple random sampling was used to select villages and households. Women empowerment in agriculture was measured by the abbreviated women empowerment in agriculture index. Even if the overall multi-dimensional five domains of empowerment index (5DE) was not a significant predictor of nutritional status in children (P > 0⋅05), sub-indicators had a pivotal role in child nutritional status. Disempowerment in decisions about input into production [AOR = 8⋅85], empowerment on control of income [AOR = 0⋅35] and availability of livestock [AOR = 0⋅38] were predictors of child stunting, whereas women's disempowerment in production decisions seems beneficiary for wasting, disempowered women have 84 % less likely to have wasted child than empowered women [AOR = 0⋅16]. Dietary and agricultural diversity [particularly livestock farming], and women's empowerment in production decisions were predictors of better nutritional outcomes in children. Therefore, a concentrated effort is needed towards strengthening the multi-dimensional empowerment of women in agriculture emphasising women's input into production decisions, dietary and agricultural diversification, mainly livestock farming.

RESUMEN

BACKGROUND: Infants born HIV-exposed yet remain uninfected (HEU) are at increased risk of poorer growth and health compared to infants born HIV-unexposed (HU). Whether maternal antiretroviral treatment (ART) in pregnancy ameliorates this risk of poorer growth is not well understood. Furthermore, whether risks are similar across high burden HIV settings has not been extensively explored. METHODS: We harmonized data from two prospective observational studies conducted in Cape Town, South Africa, and Lusaka, Zambia, to compare weight-for-age (WAZ), length-for-age (LAZ) and weight-for-length (WLZ) Z-scores between infants who were HEU and HU, converting infant anthropometric measures using World Health Organisation Growth Standards adjusted for age and sex. Linear mixed effects models were fit to identify risk factors for differences in anthropometrics at 6-10 weeks and 6 months by infant HIV exposures status and by timing of exposure to maternal ART, either from conception or later in gestation. RESULTS: Overall 773 mother-infant pairs were included across two countries: women living with HIV (WLHIV), 51% (n = 395) with 65% on ART at conception and 35% initiating treatment in pregnancy. In linear mixed effects models, WAZ and WLZ at 6-10 weeks were lower among infants who were HEU vs HU [ß = - 0.29 (95% CI: - 0.46, - 0.12) and [ß = - 0.42 (95% CI: - 0.68, - 0.16)] respectively after adjusting for maternal characteristics and infant feeding with a random intercept for country. At 6 months, LAZ was lower [ß = - 0.28 CI: - 0.50, - 0.06)] among infants who were HEU, adjusting for the same variables, with no differences in WAZ and WLZ. Within cohort evaluations identified different results with higher LAZ among infants who were HEU from Zambia at 6-10 weeks, [ß = + 0.34 CI: + 0.01, + 0.68)] and lower LAZ among infants who were HEU from South Africa [ß = - 0.30 CI: - 0.59, - 0.01)] at 6 months, without other anthropometric differences at either site. CONCLUSION: Infant growth trajectories differed by country, highlighting the importance of studying contextual influences on outcomes of infants who were HEU.

RESUMEN

Objective: By comparing and studying the changes of food intake, weight, body length, BMI, blood albumin level and other indicators of infants with Pierre-Robin Sequence (PRS) before and after Bilateral Mandible Distraction Osteogenesis operation, to explore the effect of distraction osteogenesis on PRS patients about the improvement of nutrition status. Methods: The children with PRS who admitted to the Oral and Maxillofacial Surgery Department of Guangzhou Women and Children's Medical Center from July 2015 to December 2020 were selected. All patients accepted bilateral mandible distraction osteogenesis surgery, and the pre- and post-operative indicators were recorded, such as food intake, weight, length, blood albumin level and others. BMI was calculated based on the indicators mentioned above, and comparative statistical analysis was performed. Results: 1. All patients were fed with whole milk before the first surgery, and the average calorie per kg was 91.8 kcal/kg, significantly lower than the standard (100-150 kcal/kg), suggesting the overall nutritional intake of PRS patients is low; 2. t tests for independent samples were used to analyze the pre-operative and post-operative indicators. The WFA percentile increased from 14.16 ± 2.17 to 15.01 ± 1.85% (P = 0.0048), WFA z score increased from -2.40 ± 0.18 to -1.90 ± 0.14 after the surgery (P = 0.0010), LFA percentile increased from 20.04 ± 3.48 to 33.67 ± 4.29% (P = 0.0098), LFA z score increased from -2.09 ± 0.19 to -1.42 ± 0.23 (P = 0.0009), BMI z score increased from -1.95 ± 0.22 to -1.39 ± 0.16 (P = 0.0408), ALB raised from 37.06 ± 0.51 to 42.85 ± 0.30 g/L (P < 0.001), which indicating that the physique of patients improved after the distraction osteogenesis surgery, mainly was reflected by the lifting of weight and length growth curves; the body shape also improved, indicating that the patients' nutrition status after the surgery is also improved. Conclusion: Bilateral mandible distraction osteogenesis surgery has a positive effect on the nutrition status of children with PRS. This effect is mainly reflected by the improvements of the body physical indicators after surgery.

RESUMEN

Stunting is reportedly associated with low circulating levels of essential amino acids (EAAs). This study examined the effect of a macronutrient- and micronutrient-fortified complementary food supplement (KOKO Plus) on specific plasma EAA levels and stunting in infants aged 6-18 months. In a single-blind cluster-randomized controlled trial conducted in Ghana, infants were enrolled at 6 months and followed until 18 months. Thirty-eight communities were randomly assigned to receive KOKO Plus (KP, fourteen communities, n = 321), multiple-micronutrient powder (MN, thirteen communities, n = 327), or only nutritional education as control group (NE, eleven communities, n = 318), and all groups received nutrition education. Plasma amino acids (AAs) were measured at 6, 12, and 18 months (end point). Mixed-effects models were used to assess the effect of the intervention on plasma AAs, and the relationship between plasma branched-chain AAs (BCAAs) and the risk of stunting was assessed. At the end point, total BCAA concentrations (±standard error) significantly exceeded baseline in the KP (284.2 ± 4.3 µM) and NE (289.1 ± 4.4 µM) groups but not the MN group (264.4 ± 4.1 µM). After adjustment for compliance at 200 sachets, plasma BCAAs exceeded in the KP group (284.5 ± 4.2 µM) compared to the MN group (264.6 ± 4 µM). Plasma BCAAs were positively correlated with changes in length-for-age Z-score from baseline (R = 0.327, p = 0.048). In conclusion, the plasma BCAA concentrations of infants that received KP and the NE group was significantly higher compared to the MN group but there were no differences between the KP and NE group at end point. Improved plasma BCAAs may be due to improved nutrient intake by infants exposed to KP or NE. Low BCAAs were associated with stunting, replicating the previous finding.

RESUMEN

Childhood undernutrition coupled with poor feeding practices continues to be public health problems in many parts of the world and efforts to address them remain elusive. We tested the hypothesis that women who are exposed to radio health/nutrition education will demonstrate greater nutrition and health knowledge, positive attitudes towards preventive health and better dietary diversity practices for improved child growth. We used a two-arm, quasi-experimental, non-equivalent comparison group design with pre- and post-test observations to evaluate the intervention. The study population comprised 712 mothers with children aged 6-36 months who were randomly selected from five intervention districts and one comparison district in Northern Ghana. Difference-in-difference (DID) analysis was performed to assess study outcomes. After 12-month implementation of intervention activities, the minimum dietary diversity and the minimum acceptable diet improved significantly (DID 9⋅7 percentage points, P 0⋅014 and DID 12⋅1 percentage points, P 0⋅001, respectively) in the intervention study group, compared with the comparison group. Mothers in the intervention communities had a nutrition-related knowledge, attitudes and practices score that was significantly higher than their colleagues in the comparison communities (DID 0⋅646, P < 0⋅001). The intervention did not have significant effects on the nutritional status as measured by height-for-age Z-score or weight-for-height Z-score. The data provide evidence that health and nutrition education using radio drama significantly increased health-/nutrition-related knowledge but had little effect on nutritional status.

RESUMEN

BACKGROUND: Causes of infant linear growth faltering in low-income settings remain poorly understood. Identifying age-specific risk factors in observational studies might be influenced by statistical model selection. OBJECTIVES: To estimate associations of selected household factors and infant feeding behaviors within discrete age intervals with interval-specific changes in length-for-age z-scores (LAZs) or attained LAZ, using 5 statistical approaches. METHODS: Data from a birth cohort in Dhaka, Bangladesh (n = 1157) were analyzed. Multivariable-adjusted associations of infant feeding patterns or household factors with conditional LAZ (cLAZ) were estimated for 5 intervals in infancy. Two alternative approaches were used to estimate differences in interval changes in LAZ, and differences in end-interval attained LAZ and RRs of stunting (LAZ < -2) were estimated. RESULTS: LAZ was symmetrically distributed with mean ± SD = -0.95 ± 1.02 at birth and -1.00 ± 1.04 at 12 mo. Compared with exclusively breastfed infants, partial breastfeeding (difference in cLAZ: -0.11; 95% CI: -0.20, -0.02) or no breastfeeding (-0.30; 95% CI: -0.54, -0.07) were associated with slower growth from 0 to 3 mo. However, associations were not sustained beyond 6 mo. Modifiable household factors (smoking, water treatment, soap at handwashing station) were not associated with infant growth, attained size, or stunting. Alternative statistical approaches yielded mostly similar results as conditional growth models. CONCLUSIONS: The entire infant LAZ distribution was shifted down, indicating that length deficits were mostly caused by ubiquitous or community-level factors. Early-infant feeding practices explained minimal variation in early growth, and associations were not sustained to 12 mo of age. Statistical model choice did not substantially alter the conclusions. Modifications of household hygiene, smoking, or early infant feeding practices would be unlikely to improve infant linear growth in Bangladesh or other settings where growth faltering is widespread.

RESUMEN

BACKGROUND: Successful scale-up of antiretroviral therapy (ART) during pregnancy has minimized infant HIV acquisition, and over 1 million infants are born HIV-exposed but uninfected (HEU), with an increasing proportion also exposed in utero to maternal ART. While benefits of ART in pregnancy outweigh risks, some studies have reported associations between in utero ART exposure and impaired fetal growth, highlighting the need to identify the safest ART regimens for use in pregnancy. METHODS: We compared birth anthropometrics of infants who were HEU with those HIV-unexposed (HU) in Cape Town, South Africa. Pregnant women had gestational age assessed by ultrasound at enrolment. Women living with HIV were on ART (predominately tenofovir-emtricitabine-efavirenz) either prior to conception or initiated during pregnancy. Birth weights and lengths were converted to weight-for-age (WAZ) and length-for-age (LAZ) z-scores using Intergrowth-21st software. Linear regression was used to compare mean z-scores adjusting for maternal and pregnancy characteristics. RESULTS: Among 888 infants, 49% (n = 431) were HEU and 51% (n = 457) HU. Of 431 HEU infants, 62% (n = 268) were exposed to HIV and antiretrovirals (ARVs) from conception and 38% (n = 163) were exposed to ARVs during gestation but after conception (median fetal ARV exposure of 21 weeks [IQR; 17-26]). In univariable analysis, infants who were HEU had lower mean WAZ compared with HU [ß = - 0.15 (95% Confidence Interval (CI): - 0.28, - 0.020)]. After adjustment for maternal age, gravidity, alcohol use, marital and employment status the effect remained [adjusted ß - 0.14 (95%CI: - 0.28, - 0.01]. Similar differences were noted for mean LAZ in univariable [ß - 0.20 (95%CI: - 0.42, - 0.01] but not multivariable analyses [adjusted ß - 0.18 (95%CI: - 0.41, + 0.04] after adjusting for the same variables. Mean WAZ and LAZ did not vary by in utero ARV exposure duration among infants who were HEU. CONCLUSION: In a cohort with high prevalence of ART exposure in pregnancy, infants who were HEU had lower birth WAZ compared with those HU. Studies designed to identify the mechanisms and clinical significance of these disparities, and to establish the safest ART for use in pregnancy are urgently needed.

RESUMEN

BACKGROUND: Weight for length z-score (WLZ) < - 3 is currently used to define severe acute malnutrition (SAM) among infants. However, this approach has important limitations for infants younger than 6 months of age as WLZ cannot be calculated using WHO growth standards if infant length is < 45 cm. Moreover, length for age z-score (LAZ) and weight for length z-score (WLZ) are least reliable measures, with high chances of variation, and less chances of detecting undernutrition in under 6 months infants. The objective of the current analysis was to compare WLZ with WAZ and LAZ in a cohort of Indian infants in predicting the deaths between 6 weeks and 6 months of age. METHODS: The data was from an individually randomized trial conducted in slums of Delhi, India in which infants' weight and length were measured at 6 weeks of age (at the time of the first immunization visit). Vital status of the infants was documented from 6 weeks to 6 months of age. The sensitivity, specificity, positive and negative predictive values, and positive and negative likelihood ratios were calculated for WAZ < -3, WLZ < -3, and LAZ < -3 for deaths between 6 weeks and 6 months of age. The receiver operating characteristics curve was calculated for each of the above anthropometric indicators. RESULTS: For deaths occurring between 6 weeks to 6 months of age, the specificity ranged between 85.9-95.9% for all three anthropometric indicators. However, the sensitivity was considerably higher for WAZ; it was 64.6% for WAZ < -3, 39.1% for LAZ < -3, and 25.0% for WLZ < -3. WAZ < -3 had higher area under curve (0.75; 95% CI: 0.68, 0.82) and hence, better discriminated deaths between 6 weeks and 6 months of age than WLZ < -3. The adjusted relative risk (RR 10.6, 95% CI 5.9, 18.9) and the population attributable fraction (PAF 57.9, 95% CI 38.8, 71.0%) of mortality was highest for WAZ < -3. CONCLUSIONS: We found WAZ < -3 at 6 weeks of age to be a better predictor of death in the 6 weeks to 6 months of life in comparison to WLZ < -3 and LAZ < -3 and propose that it should be considered to diagnose SAM in this age group.

RESUMEN

BACKGROUND: Naturally occurring aflatoxins may contribute to poor growth and nutritional statuses in children. OBJECTIVES: We analyzed the relationship between contemporary and lagged aflatoxin exposure and 1) length-for-age z-score (LAZ); and 2) length, knee-heel length, stunting, weight-for-age z-score (WAZ), and weight-for-length z-score (WLZ). METHODS: We conducted a longitudinal birth cohort study involving 1675 mother-infant dyads in rural Nepal. Participants were repeatedly visited from pregnancy to 2 years of age (2015-2019). One blood sample was collected during pregnancy and 4 samples were collected from the children at 3, 6, 12, and 18-22 months of age to measure concentrations of aflatoxin B1 (AFB1)-lysine adduct. Multivariate linear fixed-effects and logistic models with generalized estimating equations were used to identify associations between child growth and aflatoxin exposure. RESULTS: AFB1-lysine adducts were detected in the majority of children (at 3 months, 80.5%; at 6 months, 75.3%; at 12 months, 81.1%; and at 18-22 months, 85.1%) and in 94.3% of pregnant women. Changes in contemporary ln child AFB1-lysine adduct concentrations were significantly associated with changes in LAZ (ß, -0.05; 95% CI, -0.09 to -0.02; P = 0.003), length (ß, -0.19; 95% CI, -0.29 to -0.10; P < 0.001), knee-heel length (ß, -0.09; 95% CI, -0.13 to -0.05; P < 0.001), and WAZ (ß, -0.04; 95% CI, -0.07 to -0.005; P = 0.022). Serum aflatoxin concentrations were associated with stunting (OR, 1.18; 95% CI, 1.05-1.32; P = 0.005). Similar results were found in the models using changes in contemporary ln AFB1 adjusted for changes in child weight, with significant associations with changes in WLZ (ß, -0.07; 95% CI, -0.10 to -0.03; P < 0.001). Changes in time-lagged ln AFB1 (unadjusted and adjusted for changes in child weight) were associated with changes in length and knee-heel length. CONCLUSIONS: Our results add to the growing body of evidence confirming chronic aflatoxin exposure and suggest that exposure is significantly correlated with various negative growth outcomes, which may vary by child weight status. This trial was registered at clinicaltrials.gov as NCT03312049.

RESUMEN

@#Introduction: Stunting is the most prevalent form of child malnutrition worldwide, and is the best overall indicator of growth. This study aimed to determine the relationship between maternal characteristics and nutritional status of children aged 0-23 months based on their length/height-for-age. Method: The study used data from the 2015 Updating Survey conducted by the Philippines’ Food and Nutrition Research Institute – Department of Science and Technology. It employed a stratified multi-stage sampling technique covering all regions in the Philippines. Mothers (n=5,254) of sampled children 0-23 months were the respondents of the Maternal Health and Nutrition survey. The length-for-age z-scores (LAZ) of children and maternal characteristics were analysed. Rao-Scott Chi-square test was used for association analysis. Logistic regression was performed for model fitting. Results: A quarter (25.2%) of children aged 0-23 months in the Philippines at the time of the survey were stunted, with the highest prevalence (36.2%) observed among 12-23 months. Children being stunted or normal in height was associated with prenatal services, maternal nutritional status, education, and duration of lactation. Maternal education (OR: 0.39; p=0.012), age-appropriate breastfeeding (OR: 0.63; p=0.042), and prenatal services like tetanus toxoid vaccination (OR: 0.67; p=0.011) and ultrasound (OR: 0.71; p=0.025) lowered the likelihood of a child being stunted. Conclusion: It is recommended to strengthen and intensify service delivery among pregnant and lactating women because of the implication of maternal factors to the length-for-age status of children 0-23 months.

RESUMEN

With expanded HIV treatment and prevention programmes, most infants born to HIV-positive women are uninfected, but the patterns and determinants of their growth are not well described. This study aimed to assess growth patterns in a cohort of HIV-exposed uninfected (HEU) infants who participated in an experimental HIV vaccine trial and to test for associations with maternal and infant factors, including in-utero exposure to antiretroviral therapy (ART), mode of delivery, exclusive breastfeeding, mother's education and receipt of the vaccine. Infants in the trial were seen at regular clinic visits from birth to 48 weeks of age. From the anthropometric measurements at these visits, weight-for-age z-scores (WAZ), weight-for-length z-scores (WLZ) and length-for-age z-scores (LAZ) were computed using World Health Organization (WHO) software and reference tables. Growth patterns were investigated with respect to maternal and infant factors, using linear mixed regression models. From 94 infants included at birth, growth data were available for 75.5% at 48 weeks. The determinants of infant growth in this population are multifactorial: infant LAZ during the first year was significantly lower among infants delivered by caesarean section (p = 0.043); both WAZ and LAZ were depressed among infants with longer exposure to maternal ART (WAZ: p = 0.015; LAZ: p < 0.0001) and among infants of mothers with lower educational level (WAZ: p = 0.038; LAZ: p < 0.0001); the effect of maternal education was modified by breastfeeding practice, with no differences seen in exclusively breastfed infants. These findings inform intervention strategies to preserve growth in this vulnerable infant population.

RESUMEN

In South Asia, an estimated 38% of preschool-age children have stunted growth. We aimed to assess the effect of WHO-recommended antenatal iron, and folic acid (IFA) supplements on smaller than average birth size and stunting in South Asian children <2 years old. The sample was 96,512 mothers with their most recent birth within two years, from nationally representative surveys between 2005 and 2016 in seven South Asian countries. Primary outcomes were stunting [length-for-age Z-score (LAZ) < -2], severe stunting [length-for-age Z-score (LAZ) < -3], length-for-age Z score, and perceived smaller than average birth size. Exposure was the use of IFA supplements. We conducted analyses with Poisson, linear and logistic multivariate regression adjusted for the cluster survey design, and 14 potential confounders covering the country of the survey, socio-demographic factors, household economic status, maternal characteristics, and duration of respondent recall. The prevalence of stunting was 33%, severe stunting was 14%, and perceived smaller than average birth size was 22%. Use of antenatal IFA was associated with a reduced adjusted risk of being stunted by 8% (aRR 0.92, 95% CI 0.89, 0.95), of being severely stunted by 9% (aRR 0.91, 95% CI 0.86, 0.96) and of being smaller than average birth size by 14% (aRR 0.86, 95% CI 0.80, 0.91). The adjusted mean LAZ was significantly higher in children whose mothers used IFA supplements. Maternal use of IFA in the first four months gestation and consuming 120 or more supplements throughout pregnancy was associated with the largest reduction in risk of child stunting. Antenatal IFA supplementation was associated with a significantly reduced risk of stunting, severe stunting, and smaller than average perceived birth size and improved LAZ in young South Asian children. The early and sustained use of antenatal IFA has the potential to improve child growth outcomes in South Asia and other low-and-middle-income countries with high levels of iron deficiency in pregnancy.

RESUMEN

Objectives: Malnutrition is a characteristic feature of cleft lip with or without palate (CL/P). This study aims to retrospectively quantify the physical growth status, evaluate the feeding methods, and identify the possible correlation of CL/P types with growth failure. Methods: The length and weight of 508 infants with CL/P and 118 healthy infants were recorded at the date of admission. The weight-for-age (W/A), length-for-age (L/A), and body mass index-for-age (BMI) of the infants were calculated. Results: The L/A values were significantly lower in the infants with cleft lip (CL, 123 cases) and cleft lip with palate (CLP, 122 cases) than those of the control infants (p < 0.01). The W/A values of the infants with CP (263 cases) and CLP were significantly lower than those of the control infants (p < 0.05). However, the BMI index was not significantly different between any of the studied groups and the controls. In the mixed feeding group, the infants with CL and CP showed significantly lower L/A (p < 0.05) and W/A (p < 0.05), respectively. Conclusion: Physical growth issues were more common in the infants with CP and CLP. Because this was a retrospective study, the foods supplied to the patients were not strictly uniform, therefore, a prospective study with unified food supplement may be needed to confirm these findings.

RESUMEN

Infants and young children need diets high in nutrient density and diversity to meet the requirements of rapid growth and development. Our aim was to evaluate sociodemographic, agricultural diversity, and women's empowerment factors associated with child dietary diversity and length-for-age z-score (LAZ) in children 6-23 months using data collected as part of the Sustainable Undernutrition Reduction in Ethiopia (SURE) evaluation study baseline survey in May-June 2016. We here present a novel analysis using directed acyclic graphs (DAGs) to represent our assumptions about the causal influences between the factors of interest and the outcomes. The causal diagrams enabled the identification of variables to be included in multivariable analysis to estimate the total effects of factors of interest using ordinal logistic/linear regression models. We found that child dietary diversity was positively associated with LAZ with children consuming 4 or more food groups having on average an LAZ score 0.42 (95% CI [0.08, 0.77]) higher than those consuming no complementary foods. Household production of fruits and vegetables was associated with both increased child dietary diversity (adjusted OR 1.16; 95% CI [1.09, 1.24]) and LAZ (adjusted mean difference 0.05; 95% CI [0.005, 0.10]). Other factors positively associated with child dietary diversity included age in months, socio-economic status, maternal education, women's empowerment and dietary diversity, paternal childcare support, household food security, fruit and vegetable cultivation, and land ownership. LAZ was positively associated with age, socio-economic status, maternal education, fruit and vegetable production, and land ownership.
