RESUMO
Background: Analysis of health inequalities by ethnicity is critical to achieving the Sustainable Development Goals. In Ecuador, similar to other Latin American countries, indigenous and afro-descendant populations have long been subject to racism, discrimination, and inequitable treatment. Although in recent years, Ecuador has made progress in health indicators, particularly those related to the coverage of Reproductive, Maternal, Neonatal and Child Health (RMNCH) interventions, little is known as to whether inequalities by ethnicity persist. Methods: Analysis was based on two nationally representative health surveys (2004 and 2012). Ethnicity was self-reported and classified into three categories (Indigenous/Afro-Ecuadorian/Mixed ancestry). Coverage data for six RMNCH health interventions were stratified for each ethnic group by level of education, area of residence and wealth quintiles. Absolute inequality measures were computed and multivariate analysis using Poisson regression was undertaken. Findings: In 2012, 74.4% of women self-identifying as indigenous did not achieve the secondary level of education and 50.7% were in the poorest quintile (Q1); this profile was relatively unchanged since 2004. From 2004 to 2012, the coverage of RMNCH interventions increased for all ethnic groups, and absolute inequality decreased. However, in 2012, regardless of education level, area of residence and wealth quintiles, ethnic inequalities remained for almost all RMNCH interventions. Indigenous women had 24% lower prevalence of modern contraceptive use (Prevalence ratio [PR] = 0.76; 95% IC: 0.7-0.8); 28% lower prevalence of antenatal care (PR = 0.72; 95% IC: 0.6-0.8); and 35% lower prevalence of skilled birth attendance and institutional delivery (PR = 0.65; 95% IC: 0.6-0.7 and PR = 0.65; 95% IC: 0.6-0.7 respectively), compared with the majority ethnic group in the country. Interpretation: While the gaps have narrowed, indigenous people in Ecuador continue in a situation of structural racism and are left behind in terms of access to RMNCH interventions. Strategies to reduce ethnic inequalities in the coverage services need to be collaboratively redesigned/co-designed. Funding: This paper was made possible with funds from the Bill & Melinda Gates Foundation [Grant Number: INV-007,594/OPP1148933].
RESUMO
Abstract: Objective: To examine trends in the prevalence of metabolic syndrome (MS) and its components. Materials and methods: Data from 27 800 Mexican adults who participated in Ensanut 2006, 2012, 2016 and 2018 were analyzed. Linear regression was used across each Ensanut period to assess temporal linear trends in the prevalence of MS. Logistic regression models were obtained to calculate the percentage change, p-value for the trend and the association between the presence of MS and the risk of developing type 2 diabetes mellitus (T2DM) over 10 years using the Finnish Diabetes Risk Score (FINDRISC) and cardiovascular disease (CVD) using Globorisk. Results: The prevalence of MS in Mexican adults according to the harmonized definition was: 40.2, 57.3, 59.99 and 56.31%, in 2006, 2012, 2016 and 2018 respectively (p for trend <0.0001). In 2018, 7.62% of metabolic syndrome cases had a significant risk for incident DM2 and 11.6% for CVD. Conclusion: It is estimated that there are 36.5 million Mexican adults living with metabolic syndrome, of which 2 million and 2.5 million have a high risk of developing T2DM or cardiovascular disease respectively, over the next 10 years.
Resumen: Objetivo: Examinar las tendencias en la prevalencia del síndrome metabólico (SM) y de sus componentes. Material y métodos: Se analizaron datos de 27 800 adultos mexicanos que participaron en las Ensanut 2006, 2012, 2016 y 2018. Se utilizó regresión lineal en cada periodo de Ensanut para evaluar las tendencias lineales temporales en la prevalencia del SM. Se obtuvieron modelos de regresión logística para calcular el cambio porcentual, P para la tendencia y las asociaciones entre la SM con el riesgo de desarrollar en 10 años diabetes mellitus tipo 2 utilizando la Finnish Diabetes Risk Score (FINDRISC) y enfermedad cardiovascular utilizando Globorisk. Resultados: La prevalencia de SM en adultos mexicanos según la definición armonizada fue: 40.2, 57.3, 59.99 y 56.31%, en 2006, 2012, 2016 y 2018 respectivamente (p para tendencia <0.0001). En 2018, 7.62% de los casos de síndrome metabólico tenían un riesgo significativo de DM2 incidente y 11.6% de ECV. Conclusión: Se estima que los adultos mexicanos con síndrome metabólico son 36.5 millones; de ellos, dos millones tienen un alto riesgo de desarrollar DMT2 en los próximos 10 años y 2.5 millones enfermedades cardiovasculares.
RESUMO
BACKGROUND: The Global Diet Quality Score (GDQS) is intended as a simple global diet quality metric feasible in low- and middle-income countries facing the double burden of malnutrition. OBJECTIVE: The aim of this study was to evaluate the performance of the GDQS with markers of nutrient adequacy and chronic disease in nonpregnant nonlactating (NPNL) Mexican women of reproductive age and to compare it with the Alternate Healthy Eating Index-2010 (AHEI-2010) and the Minimum Dietary Diversity for Women (MDD-W). METHODS: We included NPNL women aged 15 to 49 y from the Mexican National Health and Nutrition Surveys (2012 and 2016) with 24-h recall (n = 2542) or a FFQ (n = 4975) (separate samples). We evaluated the correlation of the GDQS with the energy-adjusted intake of several nutrients and evaluated its association with health parameters using covariate-adjusted linear regression models. RESULTS: The GDQS was positively correlated with the intake of calcium, folate, iron, vitamin A, vitamin B-12, zinc, fiber, protein, and total fat (rho = 0.09 to 0.38, P < 0.05) and was inversely correlated with the intake of added sugar (rho = -0.37 and -0.38, P < 0.05) using both instruments, and with total fat, SFA, and MUFA only with 24-h recall data (rho = -0.06 to -0.16, P < 0.05). The GDQS was inversely associated with serum ferritin, BMI, waist circumference, and serum total and LDL cholesterol using FFQ data (P < 0.05), and was positively associated with serum folate using 24-h recall data (P < 0.05). Similar correlations and associations were observed with the MDD-W (only with micronutrients) and the AHEI-2010 (only with chronic disease-related nutrients and health markers). CONCLUSIONS: In comparison to other diet metrics, the GDQS can capture both dimensions of nutrient adequacy and health markers related to the risk of chronic disease. The performance of the GDQS was satisfactory with either 24-h recall or FFQ.

BACKGROUND: Low vaccination rates and under-detection of pertussis infections in adolescents and young adults have an impact on the transmission of pertussis to infants. In this study, the proportion of adolescents and young adults with IgG antibodies against B. pertussis antigens, representing recent infection or vaccination, was estimated in a population-based probabilistic survey in Mexico. METHODS: Sera and data from 1,581 subjects, including 1,102 adolescents and 479 young adults (10-19 and 20-25 years old, respectively) randomly selected from Mexico's 2012 National Health and Nutrition Survey, were analyzed. IgG antibodies against pertussis toxin (PT) were measured with the CDC/FDA ELISA. A subset of 234 samples was additionally tested with Bp-IgG PT ELISA kit (EUROIMMUN AG, Lubeck, Germany). Threshold values from corresponding test kits were used to identify recent infection or vaccination. RESULTS: Overall anti-PT IgG seroprevalence was 3.9% (95% CI: 2.3-6.3); 3.1% (95% CI: 1.9-5.0) in adolescents, and 4.9% (95% CI: 2.2-11) in young adults. Seroprevalence did not significantly vary by sex, socioeconomic status, region or rural/urban location. Compared to the CDC/FDA ELISA, the EUROIMMUN test showed a 76% sensitivity and 88% specificity. The weighted estimates represent a considerable burden of recent infection in adolescents and young adults; however, most adolescents and adults were seronegative and, therefore, susceptible to pertussis infection. CONCLUSION: Since booster vaccination to B. pertussis after toddlerhood is not recommended in the Mexican national policy, anti-PT IgG seropositivity may be reasonably attributed to recent infection. Assessing pertussis seroprevalence requires careful consideration of the diagnostic test threshold interpretation and epidemiological model used.

OBJECTIVE: To examine the association between household food insecurity and overweight, obesity and abdominal obesity in Mexican adults. DESIGN: Cross-sectional study. SETTING: We analysed data from the Mexican Halfway National Health and Nutrition Survey 2016, a nationally representative survey that accounted for rural and urban areas in four regions of Mexico: North, Centre, Mexico City and South. PARTICIPANTS: Adults from 20 to 59 years old (n 5456, which represents 45 804 210 individuals at the national level). RESULTS: 70·8 % of the Mexican adults had some degree of household food insecurity. This situation showed larger proportions (P < 0·05) among indigenous people, those living in a rural area, in the Southern region or the lowest socio-economic quintiles. The prevalence of obesity and abdominal obesity was higher in female adults (P < 0·001), with the highest proportions occurring among those experiencing severe household food insecurity. Among women, mean BMI and waist circumference were higher as household food insecurity levels increased (P < 0·001). According to multivariate logistic regression models, severe household food insecurity showed to be positively associated with obesity (OR: 2·36; P = 0·001) in Mexican adult females. CONCLUSIONS: Our findings confirm the association between household food insecurity and obesity among Mexican women. Given the socio-demographic characteristics of the food-insecure population, it is alarming that prevailing socio-economic inequalities in the country might also be contributing to the likelihood of obesity. Therefore, it is crucial to maintain and bolster surveillance systems to track both problems and implement adequate policies and interventions.

BACKGROUND: vitamin D (VD) may be a protective factor for retinoblastoma, though no temporal association has been reported during pregnancy or the child's first year of life. Serum VD concentrations are determined by both distal (DF) and proximal factors (PF). OBJECTIVE: To identify if DF and PF can predict VD insufficiency (VDI) and VD deficiency (VDD) in women of childbearing age; and to test whether maternal exposure to DF and PF during pregnancy and a child's exposure during the first 11.9 months postpartum are associated with sporadic retinoblastoma (SRb) in children. METHODS: This is a secondary analysis of data from the Epidemiology of SRb in Mexico (EpiRbMx) study and the National Health and Nutrition Survey 2018-2019 (ENSANUT 2018-2019, for its acronym in Spanish). The association of DF and PF with VDD or VDI was estimated using ENSANUT 2018-2019, and the association of DF and PF with SRb using EpiRbMx. All were estimated using logistic regression, with comparable samples selected from ENSANUT 2018-2019 and EpiRbMx. RESULTS: Altitude, latitude and obesity predicted VDI and VDD in ENSANUT women. In EpiRbMx, residence in a rural location during pregnancy increased the risk of SRb. For children, rural residence and latitude increased the risk of SRb, while the number of days exposed to the spring-summer season during months 6 to 11.9 of life was protective. CONCLUSIONS: risk of VDI and VDD in women (ENSANUT 2018-2019) increased with altitude, urban dwelling, overweight and obesity. The child and mother's place of residence, including altitude, latitude and rural classification were important predictors of SRb in EpiRbMx.

Abstract Objective: To describe trends in zinc deficiency (ZD) prevalence among preschool-age Mexican children, and explore differences in this trend among beneficiaries of the conditional cash transfer program Progresa/Oportunidades/ Prospera (CCT-POP). Materials and methods: The serum zinc information of children aged 1-4 who participated in the ENN 1999, Ensanut 2006 and Ensanut 2018-19 was analyzed. ZD was categorized according to IZiNCG cutoff values. Logistic regression models were used to identify personal participant characteristics associated with ZD trends, and tests for interactions between survey CCT-POP beneficiaries were applied. Results: ZD decreased by 22.3 percentage points (pp) between ENN 1999 and Ensanut 2018-19; among CCT-POP beneficiaries, the decrease was 58.6 pp. Overweight was associated with higher odds of ZD (OR=2.18, p=0.023). Conclusions: In the last 19 years, ZD declined significantly among preschool-age Mexican children. Child beneficiaries of the social program CCT-POP showed the largest reduc- tion of ZD.

Material y métodos: Se analizó información de Zn sérico en niños de 1-4 años participantes de la ENN 1999, Ensanut 2006 y 2018-19. Se categorizó la DZ de acuerdo con los puntos de corte propuestos por el IZiNCG. Se emplearon modelos de regresión logística para identificar las características asociadas con la tendencia en la DZ y se evaluó la interacción con beneficiarios del PTM-POP. Resultados: La DZ disminuyó 22.3 puntos porcentuales (pp) entre la ENN 1999 y la Ensanut 2018-19, y disminuyó 58.6 pp entre beneficiarios del PTM-POP en el mismo periodo. El sobrepeso se asoció con mayor riesgo de DZ (RM=2.18, p=0.023). Conclusiones: La DZ disminuyó significativamente en los últimos 19 años en México. Los niños beneficiarios del PTM-POP mostraron las mayores reducciones en la DZ.
RESUMO
Abstract Objective: To describe the current status of anemia and iron deficiency (ID), as well as associated sociodemographic characteristics, in older adults (OA). Materials and methods: Serum and capillary blood samples from a sample of OA participants (n=2 902) from the Ensanut 2018-19 were analyzed. ID was defined as s-ferritin<15 μg/L, and anemia was defined according to World Health Organization standards. Logistic regression models were used to associate the characteristics of OA with anemia and ID. Results: Of the OA analyzed, anemia was present in 28.4%, ID in 5% and iron deficiency anemia in 2.07%. Diabetes (OR=2.14), renal insufficiency (OR=10.4), higher age, and urban dwelling (OR=1.35) were conditions associated with higher odds for anemia (p<0.05). Belonging to the 70-79 year age group was the only condition associated with higher odds for ID (OR=1.86, p<0.05). Conclusions: Anemia affects a high proportion of OA, and ID is not the main contributor to anemia. Chronic comorbidities help explain the anemia problem in OA.

RESUMO
The associations of lifestyle and environment with metabolic syndrome (MetS) and cardiovascular disease have recently resulted in increased attention in research. This study aimed to examine interactive associations among carbohydrate and fat intake, physical environment (i.e., elevation and humidity), lifestyle, and MetS among Ecuadorian adults. We used data from the Ecuador National Health and Nutrition Survey 2012 (ENSANUT-ECU), with a total of 6023 participants aged 20 to 60 years included in this study. Logistic regression was used to determine the association of status of carbohydrate and fat intake, low-carbohydrate high-fat diet (LCHF) and medium-carbohydrate and fat (MCF) diet with MetS, where the high-carbohydrate low-fat (HCLF) diet was used as a reference. Women with LCHF and MCF diets showed lower prevalence of increased blood pressure (OR = 0.34, 95% CI: 0.19-0.59; OR = 0.50, 95% CI: 0.32-0.79, respectively). Women with MCF diet also showed lower prevalence of elevated fasting glucose (OR = 0.58, 95% CI: 0.37-0.91). Moreover, there were negative associations between MetS and reduced HDL cholesterol in women with MCF diet residing in low relative humidity (OR = 0.66, 95% CI: 0.45-0.98) and in women with LCHF diet residing at a high elevation (OR = 0.37, 95% CI: 0.16-0.86). Additionally, higher prevalence of increased waist circumference was observed in men with both MFC and LCHF diets who were physically inactive (OR = 1.89, 95% CI: 1.12-3.20; OR = 2.34, 95% CI: 1.19-4.60, respectively) and residing in high relative humidity (OR = 1.90, 95% CI: 1.08-2.89; OR = 2.63, 95% CI: 1.32-5.28, respectively). Our findings suggest that LCHF intake is associated with lower blood pressure, while MCF intake is associated with lower blood pressure and fasting glucose in Ecuadorian women. Furthermore, the associations of carbohydrate and fat intake with prevalence of MetS can be modified by physical activity, relative humidity, and elevation. The obtained outcomes may provide useful information for health programs focusing on dietary intake and lifestyle according to physical environment of the population to promote health and prevent metabolic diseases.

PURPOSE: Approximately 70% of adults in Mexico are overweight or obese. Unhealthy lifestyle behaviors are also prevalent. We examined the association of three lifestyle behaviors with body mass index (BMI) categories in adults from Mexico. METHODS: We used publicly available data from the ENSANUT 2016 survey (n = 6419). BMI was used to categorize participants. Differences in sleep duration, suffering from symptoms of insomnia, TV watching time, time in front of any screen, vigorous physical activity (yes vs no), moderate physical activity (> 30 min/day-yes vs. no) and walking (> 60 min/day-yes vs. no) were compared across BMI groups using adjusted linear and logistic regression analyses. RESULTS: Thirty-nine percent of participants were overweight and 37% obese. Time in front of TV, in front of any screen, sleep duration and physical activity were significantly associated with overweight and obesity. Compared to normal weight participants, participants in the obese II category spend on average 0.60 h/day (95% CI 0.36-0.84, p = 0.001) and participants in the obese III category 0.54 h/day (95% CI 0.19-0.89, p < 0.001) more in front of any screen; participants in the obese II category reported 0.55 h/day less sleep (95% CI - 0.67 to - 0.43, p < 0.001); participants in the obese III category were less likely to engage in vigorous activity (OR = 0.60, 95% CI 0.43-0.84, p ≤ 0.003), or walking (OR = 0.65, 95% CI 0.49-0.88, p = 0.005). CONCLUSION: Screen time, sleeping hours, and physical activity were associated with overweight and obesity. However, these associations were not consistent across all BMI categories. Assuming established causal connections, overweight individuals and individuals with obesity would benefit from reduced screen time and engaging in moderate/vigorous physical activity. LEVEL OF EVIDENCE: Level III: observational case-control analytic study.

The effects of the physical environment on metabolic syndrome (MetS) are still largely unexplained. This study aimed to analyze the associations of relative humidity of residence, lifestyles, and MetS among Ecuadorian adults. Data from 6024 people aged 20 to 60 years were obtained from an Ecuador national population-based health and nutrition survey (i.e., ENSANUT-ECU, 2012) and the mean annual relative humidity (%) from the Ecuador National Institute for Meteorology and Hydrology (2012). Odds ratio (OR) with 95% confidence intervals (CI) for MetS according to groups of relative humidity were calculated using multiple logistic regression. Living in high relative humidity (>80%) increased ORs of reduced high-density lipoprotein (HDL) cholesterol (1.25; 95 % CI, 1.06-1.56) and MetS (OR = 1.20; 95 % CI,1.01-1.42) in women. Furthermore, physically active men living in high relative humidity showed lower OR of elevated triglycerides (0.56; 95 % CI,0.37-0.85) while menopausal women living in high relative humidity showed increased ORs of MetS (5.42; 95 % CI, 1.92-15.27), elevated blood pressure (3.10; 95 % CI, 1.15-8.35), and increased waist circumference (OR = 1.34; 95 % CI, 1.09-1.63). Our results show that residence in high relative humidity and menopausal status increase ORs of MetS and its components in Ecuadorian women; however, physical activity significantly reduces the OR of elevated triglycerides in men. The obtained findings may help make public health policies regarding environmental humidity management, nutritional education, menopausal care, and physical activity promotion to prevent the onset of MetS among Ecuadorian adults.

In school age children and adolescents, anemia might cause lower cognitive function and attention span, which in turn could diminish human capital accumulation. As children born in low-income households are more likely to be anemic, this may prevent many individuals from overcoming the intergenerational poverty traps. In this paper, we used data from the Mexican National Health and Nutrition Survey 2012 and focused on a sample of adolescents between 12 and 19 years of age to study the relationship between attending school without delay-our proxy for school performance-and anemia. We found a statistically significant association between the two variables. If this relationship is causal, the economic burden linked to the loss of school years could well exceed the costs associated with programs aimed at reducing the prevalence of anemia in vulnerable populations. Our results provide additional support to the existing literature on anemia as a significant barrier to school achievement.

OBJECTIVE: We describe the profile of the population aged 20 years and over, who go for a diabetes and hypertension screening test. MATERIALS AND METHODS: Based on the information from Ensanut 2018-19, two multiple logistic regression models were obtained with variables associated with the detection of diabetes and hypertension. Profiles were generated based on combinations of the variables included in the model. Increases in probabilities were plotted according to profiles. RESULTS: Individuals with a family history of the disease, comorbidities or unhealthy lifestyles composed the group that seek for diabetes and hypertension screening. CONCLUSIONS: The health system should look for those with the highest risk of developing or having undiagnosed diabetes and hypertension, using risk questionnaires, type score. This population should undergo screening studies and, where appropriate, diagnoses.

Materials and methods: Based on the information from Ensanut 2018-19, two multiple logistic regression models were obtained with variables associated with the detection of diabetes and hypertension. Profiles were generated based on combinations of the variables included in the model. Increases in probabilities were plotted according to profiles. Results: Individuals with a family history of the disease, comorbidities or unhealthy lifestyles composed the group that seek for diabetes and hypertension screening. Conclusions: The health system should look for those with the highest risk of developing or having undiagnosed diabetes and hypertension, using risk questionnaires, type score. This population should undergo screening studies and, where appropriate, diagnoses.

Resumen: Objetivo: Estimar la prevalencia y distribución de anemia en mujeres mexicanas y su asociación con factores sociodemográficos y la diversidad de la dieta. Material y métodos: Se incluyeron mujeres en edad fértil de la encuesta probabilística Ensanut 100k, que representa a los hogares con menos capacidades económicas. Se estimó la prevalencia de anemia mediante concentración de hemoglobina, con información sociodemográfica, de salud, inseguridad alimentaria y diversidad de la dieta. Resultados: El 34.3% de las mujeres presentó anemia; los factores protectores para anemia fueron pertenecer al tercil 3 de condición de bienestar (OR=0.26, IC95% 0.16-0.61), alta diversidad de la dieta en áreas rurales (OR=0.57, IC95%0.36-0.92), así como vivir en un hogar con seguridad alimentaria. Conclusiones: Es necesario implementar acciones de detección y atención temprana de la anemia en las mujeres de edad fértil, así como identificar las causas subyacentes y fortalecer y reformular estrategias para prevenirla.
Abstract: Objective: To estimate the prevalence and distribution of anemia in Mexican women and their association with sociodemographic factors and diet diversity. Materials and methods: We analyzed information of women in childbearing age. The Ensanut 100k is a probabilistic survey that over-represents households with less economic capacity. Anemia was estimated using hemoglobin concentration. We collected sociodemographic and health information, food insecurity, and dietary diversity. Results: 34.3% of the women presented anemia, belong to tertile 3 of welfare status is a protective factor for anemia (OR= 0.26, 95%CI 0.16-0.61), and living in a household with food security, as well as high diversity of the diet in rural women (OR= 0.57, 95%CI 0.36-0.92). Conclusions: It is necessary to implement actions of detection and early attention of the anemia in women in childbearing age, identification of its underlying causes, strengthening and reformulation of strategies to prevent it.

OBJECTIVE: To describe trends across the intake distribution of total, manufactured and homemade sugar-sweetened beverages (SSB) from 1999 to 2012, focusing on high SSB consumers and on changes by socio-economic status (SES) subgroup. DESIGN: We analysed data from one 24 h dietary recall from two nationally representative surveys. Quantile regression models at the 50th, 75th and 90th percentiles of energy intake distribution of SSB were used. SETTING: 1999 Mexican National Nutrition Survey and 2012 Mexican National Health and Nutrition Survey.ParticipantsSchool-aged children (5-11 years) and women (20-49 years) for trend analyses (n 7718). Population aged >1 year for 2012 (n 10 096). RESULTS: Over the 1999-2012 period, there were significant increases in the proportion of total and manufactured SSB consumers (5·7 and 10·7 percentage points), along with an increase in per-consumer SSB energy intake, resulting in significant increases in per-capita total SSB energy intake (142, 247 and 397 kJ/d (34, 59 and 95 kcal/d) in school-aged children and 155, 331 and 456 kJ/d (37, 79 and 109 kcal/d) in women at the 50th, 75th and 90th percentile, respectively). Total and manufactured SSB intakes increased sharply among low-SES children but remained similar among high-SES children during this time span. CONCLUSIONS: Large increases in SSB consumption were seen between 1999 and 2012 during this pre-tax SSB period, particularly for the highest consumers. Trends observed in school-aged children are a clear example of the nutrition transition experienced in Mexico. Policies to discourage high intake of manufactured SSB should continue, joined with strategies to encourage water and low-calorie beverage consumption.

Mexican and international authorities provide guidelines for milk and beverage consumption for young children. This study classifies beverages as appropriate or inappropriate by age (0-5.9, 6-11.9, and 12-23.9 months) and details consumption patterns, amounts consumed, and the associated socio-demographic characteristics. Analysis of the Mexican National Nutrition and Health Survey (ENSANUT 2012) was conducted (n = 949). Among 0-5.9 month olds, 66.7% consumed either breast milk, infant formula, or a combination with no other beverages, whereas 29.3% consumed breast milk and/or infant formula with water (mean = 58 g/day) and/or other beverages (mean = 115 g/day), such as 100% fruit juice, milk, and sugar-sweetened beverages (SSBs). For infants 6-11.9 months, appropriate beverages include breast milk, infant formula, and water; only 40.2% met these recommendations. Many 6-11.9 month olds consumed age-inappropriate beverages, including milk (31%) and SSBs (35%). After 12 months of age, appropriate beverages include water, milk, and a limited amount of 100% fruit juice and SSBs; 32.4% complied fully, 18.3% consumed appropriate and inappropriate beverages, and 49.3% consumed only inappropriate beverages. Among 12-23.9 month olds, 58% consumed milk, 18% juice, and 42% water while 63% consumed SSBs. Many infants and young children are not compliant with Mexican and international breastfeeding and complementary feeding guidelines for beverages. Communication and guidance about age-appropriate beverages should be improved.

PURPOSE: Obesity and depression are among the leading causes of disability in Mexico, but their association has not been explored yet. The aim of the current study was to investigate the association between obesity and depression in Mexican population. METHODS: We used data from the health and nutrition survey (ENSANUT 2012), which is representative of the Mexican population. Obesity was determined using the body mass index (BMI) and abdominal obesity by measuring waist circumference. Depressive symptoms were reported using the Center for Epidemiological Studies Depression Scale Short-Form (CES-D-SF, scale 0-21). Regression analyses were performed between obesity and depression, adjusting for gender, age, living with a partner, education, and diabetes history. RESULTS: Obese women had 1.28 (95% CI 1.07-1.53) times the odds of having depression in comparison with normal-weight women, whereas no association was found for men (OR 0.94; 95% CI 0.74-1.19). A significant association between BMI and depressive symptoms score (ß = 0.05, 95% CI 0.02-0.07) was present in women, but no association was found for men (ß = - 0.02, 95% CI - 0.05 to 0.00). There was a statistically significant association between waist circumference and depression scores again for women (ß = 0.03, 95% CI 0.01-0.04) but not for men (ß = 0.00, 95% CI - 0.01 to 0.01). No associations were found between abdominal obesity and depression for both genders. No association was found between different obesity severity levels and depression for both genders. CONCLUSION: Obesity was associated with depression in Mexican women, whereas no association was found between obesity and depression in men.
