RESUMO
OBJECTIVE: To determine the mediating effect of direct preschool and parent nutrition education on changes in skin carotenoids scores over 2 years in children of Mexican heritage. DESIGN: In a quasi-experimental, community-based study, two school districts were randomly assigned to either a comparison group (parent workshops unrelated to nutrition) or a childhood obesity prevention intervention group which included nutrition education at family nights for parents and at school for children. Changes in skin carotenoid intensity scores (diffCAROT, year 2015 minus 2013) were measured in children as a proxy for fruit and vegetable consumption using Resonance Raman Spectroscopy. SETTING: Two rural, low-income, school districts from a county in California's Central Valley. PARTICIPANTS: 316 Mexican heritage families with children aged 3-8 years. RESULTS: Intervention group children improved over 2 years in skin carotenoid scores relative to comparison group children (diffCAROT mean +1419 (sd 9540) v. -3473 (sd 9272), P = 0·0001). Parent attendance at nutrition education classes partially mediated the intervention effect on diffCAROT (P = 0·02). Controlling for child's age and other covariates, participation in preschool during the study had a significant positive effect on diffCAROT among intervention children compared with controls (P < 0·03), whereas no significant difference by group was observed among those not enrolled in preschool or already enrolled in elementary school. CONCLUSIONS: Programmes that combine direct parent and preschool nutrition education may be effective in low-income Mexican heritage families to improve children's intake of fruit and vegetables.

BACKGROUND: Obesity and overweight have increased dramatically in the United States over the last decades. The complexity of interrelated causal factors that result in obesity needs to be addressed within the cultural dynamic of sub-populations. In this study, we sought to estimate the effects of a multifaceted, community-based intervention on body mass index (BMI) among Mexican-heritage children. METHODS: Niños Sanos, Familia Sana (Healthy Children, Healthy Family) was a quasi-experimental intervention study designed to reduce the rate of BMI growth among Mexican-heritage children in California's Central Valley. Two rural communities were matched based on demographic and environmental characteristics and were assigned as the intervention or comparison community. The three-year intervention included parent workshops on nutrition and physical activity; school-based nutrition lessons and enhanced physical education program for children; and a monthly voucher for fruits and vegetables. Eligible children were between 3 and 8 years old at baseline. Intent-to-treat analyses were estimated using linear mixed-effect models with random intercepts. We ran a series of models for each gender where predictors were fixed except interactions between age groups and obesity status at baseline with intervention to determine the magnitude of impact on BMI. RESULTS: At baseline, mean (SD) BMI z-score (zBMI) was 0.97 (0.98) in the intervention group (n = 387) and 0.98 (1.02) in the comparison group (n = 313) (NS). The intervention was significantly associated with log-transformed BMI (ß = 0.04 (0.02), P = 0.03) and zBMI (ß = 0.25 (0.12), P = 0.04) among boys and log-transformed BMI among obese girls (ß = - 0.04 (0.02), P = 0.04). The intervention was significantly and inversely associated with BMI in obese boys and girls across all age groups and normal weight boys in the oldest group (over 6 years) relative to their counterparts in the comparison community. CONCLUSIONS: A community-based, multifaceted intervention was effective at slowing the rate of BMI growth among Mexican-heritage children. Our findings suggest that practitioners should consider strategies that address gender disparities and work with a variety of stakeholders to target childhood obesity.

OBJECTIVE: To examine factors related to attendance of Mexican-heritage parents at community-based nutrition classes to prevent childhood obesity. METHODS: Starting in 2011, interviewers collected baseline data from Niños Sanos Familia Sana (Healthy Children, Healthy Families) participants in rural California. Educators maintained attendance logs from 2012 to 2014. Informed by the Theory of Planned Behavior, interviewers administered an exit survey in 2015 to collect data on attitudes, subjective norms, health motivations, and perceived control related to attendance. Multivariable ordinal logistic regression analysis examined the correlates of attendance (nâ¯=â¯194, intervention group only). RESULTS: Controlling for mother's age, marital status, acculturation, and employment, attitudes and subjective norms were significantly related to attendance (odds ratioâ¯=â¯1.27; 95% confidence interval [CI], 1.18-1.37; P < .001). CONCLUSIONS AND IMPLICATIONS: In these Mexican-heritage participants, attitudes and subjective norms were significant correlates of attendance. The Theory of Planned Behavior may shed light on attendance of high-risk groups but further testing of instruments is needed.

Recent recommendations for US food assistance programs are intended to ensure foods provided through these programs help households consume a varied, healthful diet. From a policy viewpoint, it is important to examine the impact of economic incentives to purchase healthy foods across subpopulations, particularly low-income Latinos, who comprise 40% of the WIC program nationwide. Our aim was to determine how rural, Mexican-heritage households (N = 227) residing in California's Central Valley distributed fruit and vegetable (F/V) voucher spending among F/V subgroups and specific items over a 1-year period. Households contained at least one child who was between 3 and 8 years old at baseline and had a parent of Mexican-heritage. F/V voucher purchase data were collected via grocery store scanners. Expenditure and frequency shares of subgroups and individual items were analyzed to determine purchasing habits. Fruits were the most commonly purchased subgroup, representing 55% of spending and 45% of frequency. Households allocated low percentages of their voucher to dark green and red/orange vegetables-7 and 9% respectively. Approximately 20% of purchases were good potassium sources and 30% of purchases were good fiber sources. Many of the most frequently purchased items were of cultural significance (tomatillo, chayote, chili/jalapeño pepper, and Mexican squash). This study suggests that economic incentives can contribute important nutrients to participants' diets and targeted vouchers provided by food assistance programs should continue to include culturally important foods and be aware of the cultural values of their participants.

The purpose of this study was to examine relative validity of a food frequency questionnaire (FFQ) to measure food acculturation in young Mexican-origin children. In 2006, Spanish-speaking staff interviewed mothers in a community-based sample of households from Ventura, California (US) (n = 95) and Guanajuato, Mexico (MX) (n = 200). Data included two 24-h dietary recalls (24-DR); a 30-item FFQ; and anthropometry of the children. To measure construct, convergent, and discriminant validity, data analyses included factor analysis, Spearman correlations, t-test, respectively. Factor analysis revealed two constructs: 1) a US food pattern including hamburgers, pizza, hot dogs, fried chicken, juice, cereal, pastries, lower fat milk, quesadillas, and American cheese and 2) a MX food pattern including tortillas, fried beans, rice/noodles, whole milk, and pan dulce (sweet bread). Out of 22 food items that could be compared across the FFQ and mean 24-DRs, 17 were significantly, though weakly, correlated (highest r = 0.62, for whole milk). The mean US food pattern score was significantly higher, and the MX food pattern score, lower in US children than in MX children (p < 0.0001). After adjusting for child's age and gender; mother's education; and household size, the US food pattern score was positively related to body mass index (BMI) z-scores (beta coefficient: +0.29, p = - 0.004), whereas the MX food pattern score was negatively related to BMI z-scores (beta coefficient: -0.28, p = 0.002). This tool may be useful to evaluate nutrition education interventions to prevent childhood obesity on both sides of the border.

INTRODUCTION: In California's agricultural Central Valley, the rate of childhood obesity is higher than the national average. Adequate physical activity contributes to obesity prevention and its assessment is useful to evaluate the impact of interventions. METHODS: Niños Sanos, Familia Sana (Healthy Children, Healthy Family [NSFS]) uses community-based participatory research to implement an intervention program to reduce childhood obesity among people of Mexican origin in the Central Valley. Anthropometric measurements were conducted on more than 650 children enrolled in NSFS. Physical activity data from a subgroup of children aged 4 to 7 years (n = 134) were collected via a wearable accelerometer. RESULTS: Children were classified on the basis of age and sex-adjusted body mass index as healthy weight (57.7%); overweight (19.3%), or obese (23%). Logistic regression showed that moderate to vigorous physical activity (MVPA) was associated with a child's likelihood of having a healthy BMI (odds ratio: 1.03; 95% CI, 1.01-1.05; P = .017). CONCLUSION: NSFS's community-based participatory approach resulted in successful use of a commercial electronic device to measure physical activity quantity and quality in this hard-to-reach population. Promotion of adequate daily MVPA is an appropriate and necessary component of NSFS's childhood obesity prevention strategy.

Latino children experience higher rates of obesity than do non-Latino white children. Family-centered nutrition interventions can slow the rate of weight gain in this population. Niños Sanos, Familia Sana (Healthy Children, Healthy Family) is a 5-year, community-based, participatory research study that targets rural Mexican-origin farmworker families with children aged 2 to 8 years in California's Central Valley. Adaptation of a culturally relevant obesity prevention program involved qualitative research to tailor key obesity prevention messages, pilot testing and implementation of key messages and activities at family nights, and continual modification to incorporate culturally innovative elements. Of the 238 families enrolled, 53% (125) attended the recommended minimum of 5 (of 10 possible) classes during the first year. A university and community partnership can guide development of a culturally tailored obesity prevention program that is suitable for reaching a high-risk Mexican-origin audience through cooperative extension and other public health programs.

OBJECTIVE: The present paper examines the influence of age and gender on food patterns of Latino children. DESIGN: Data are from baseline of a 5-year, quasi-experimental obesity prevention study: Niños Sanos, Familia Sana (NSFS; Healthy Children, Healthy Families). In 2012, the researchers interviewed Latino parents, using a thirty-item questionnaire to ask about their children's food consumption and feeding practices. Statistical tests included t tests and ANCOVA. SETTING: Rural communities in California's Central Valley, USA. SUBJECTS: Two hundred and seventeen parents (87-89% born in Mexico) and their children (aged 2-8 years). RESULTS: Fifty-one per cent of the children were overweight or obese (≥85th percentile of BMI for age and gender). Mean BMI Z-scores were not significantly different in boys (1·10 (SD 1·07)) and girls (0·92 (SD 1·04); P=0·12). In bivariate analysis, children aged 2-4 years consumed fast and convenience foods less often (P=0·04) and WIC (Supplemental Nutrition Program for Women, Infants, and Children)-allowable foods more often than children aged 5-8 years (P=0·01). In ANCOVA, neither age nor gender was significantly related to food patterns. Mother's acculturation level was positively related to children's consumption of fast and convenience foods (P=0·0002) and negatively related to consumption of WIC foods (P=0·01). Providing role modelling and structure in scheduling meals and snacks had a positive effect on the vegetable pattern (P=0·0007), whereas meal skipping was associated with more frequent fast and convenience food consumption (P=0·04). CONCLUSIONS: Acculturation and child feeding practices jointly influence food patterns in Latino immigrant children and indicate a need for interventions that maintain diet quality as children transition to school.

The purpose was to compare maternal perceptions, feeding practices, and overweight status of children in immigrant households in California (US) with a cohort in Guanajuato, Mexico (MX). In 2006, staff interviewed mothers and weighed and measured their children, 1-6 years (US: n = 95 and MX: n = 200). Prevalence of overweight [body mass index z-score (BMIZ) >1.0 and <1.65] and obesity (BMIZ > 1.65) was 21.1 and 28.4% in the US respectively, compared to 11.5 and 12.9% in MX (p < 0.001). No differences were observed in maternal ability to identify correctly the child's weight status or ever being told the child was overweight. US children ate away from home more often (p < 0.0001), had fewer family meals (p < 0.0001), and played outdoors less often than MX children (p < 0.0002). Further analyses should examine how differences in eating and activity patterns explain the disparity in childhood obesity across the countries.

BACKGROUND: Overweight and obese children are likely to develop serious health problems. Among children in the U.S., Latino children are affected disproportionally by the obesity epidemic. Niños Sanos, Familia Sana (Healthy Children, Healthy Family) is a five-year, multi-faceted intervention study to decrease the rate of BMI growth in Mexican origin children in California's Central Valley. This paper describes the methodology applied to develop and launch the study. METHODS/DESIGN: Investigators use a community-based participatory research approach to develop a quasi-experimental intervention consisting of four main components including nutrition, physical activity, economic and art-community engagement. Each component's definition, method of delivery, data collection and evaluation are described. Strategies to maintain engagement of the comparison community are reported as well. DISCUSSION: We present a study methodology for an obesity prevention intervention in communities with unique environmental conditions due to rural and isolated location, limited infrastructure capacity and limited resources. This combined with numerous cultural considerations and an unstable population with limited exposure to researcher expectations necessitates reassessment and adaptation of recruitment strategies, intervention delivery and data collection methods. Trial registration # NCT01900613. TRIAL REGISTRATION: NCT01900613.

Little is known about toddler feeding practices, particularly among Mexican American mothers. A convenience sample of 18 Mexican-American mothers with toddlers participated in individual in-depth interviews. In determining what to feed her child, mothers tended to cater to the child's preferences rather than exposing the child to different foods or repeating attempts to feed previously unaccepted foods. In deciding when to feed food or beverage, more than half said the child's cue was primary. Findings indicate that an indulgent feeding style may dominate compared to other styles in the toddler developmental stage in Mexican-American mothers.

OBJETIVO: Validar una versión de la Escala de Seguridad Alimentaria (FSS) en comunidades de la Sierra de Manatlán, Jalisco. MATERIAL Y MÉTODOS: Usando grupos focales se modificó la FSS. Posteriormente se aplicó una encuesta a mujeres con niños preescolares. La FSS se validó correlacionándola con el inventario de alimentos del hogar y con la variedad de dieta de la entrevistada. La encuesta incluyó un cuestionario socio-económico. RESULTADOS: El 44 por ciento de los hogares indicaron inseguridad alimentaria leve, 33 por ciento hambre moderada y 19.7 por ciento hambre severa. La inseguridad alimentaria estuvo inversamente correlacionada con el inventario de alimentos (r=-0.36**), alimentos de origen animal (r=-0.28**), lácteos (r=-0.25**), alimentos procesados (r=-0.37**), frutas (r=-0.21*) y verduras (r=-0.28**); *p<0.05, **p< 0.01. La inseguridad alimentaria estuvo asociada a la baja variedad de dieta (r=-0.23; p=0.02). Estas asociaciones se mantuvieron en modelos multivariados. CONCLUSIONES: La FSS es un instrumento útil para vigilar la inseguridad alimentaria en zonas rurales de Jalisco.

OBJECTIVE: To validate a version of the Food Security Scale (FSS) in communities located in Sierra de Manantlán, Jalisco. MATERIAL AND METHODS: Using focus groups, the FSS was modified to fit the Mexican context. Subsequently, a survey was applied to women with pre-school aged children. The FSS was validated in correlation with a household food inventory and the dietary variety of the individual being interviewed. The interview also included a socioeconomic questionnaire. RESULTS: Forty-four percent of the households reported mild food insecurity, 33% reported moderate hunger and 19.7% reported severe hunger. Food insecurity was significantly and inversely correlated with the number of food items in the household (r=-0.36**), animal source foods (r=-0.28**), dairy products (r=-0.25*), processed foods (r=-0.37**), fruits (r=-0.21*), and vegetables (r=-0.28**); *p<0.05, **p< 0.01. Food insecurity was also associated with low dietary variety (r=-0.23, p=0.02). These associations were maintained in multivariate models. CONCLUSIONS: The FSS is a useful tool for monitoring food insecurity in rural regions of Jalisco.

OBJECTIVE: The purpose of this research was to examine the relationship of child-feeding practices and other factors to overweight in low-income Mexican-American preschool-aged children. DESIGN: Cross-sectional survey with anthropometric measurements of mothers and target children. Trained bilingual staff interviewed the parents to collect data on child-feeding strategies, food patterns, child's health history, parental acculturation level, food insecurity, and other household characteristics. Subjects and setting Complete data were available from 204 low-income Mexican-American parents residing in California with at least one child aged 3 to 5 years. Outcomes measured Risk of overweight was defined as body mass index (BMI) (measured as weight [in kilograms]/height [in meters](2)) >/=85th percentile and overweight was defined as BMI >/=95th percentile. The Student t test, chi(2) test, and logistic regression were used. RESULTS: Three variables were positively related to risk of overweight: birth weight (odds ratio [OR], 2.31; 95% confidence interval [CI], 1.11 to 4.82), mother's BMI >/=30 (OR, 2.05; 95% CI, 1.11 to 3.79), and juice intake (OR, 2.33; 95% CI, 1.09 to 4.98). Being enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children was negatively related to risk of overweight (OR, 0.40; 95% CI, 0.21 to 0.75). Additional variables related to overweight were monthly income >$1,500 (OR, 2.33; 95% CI, 1.00 to 5.42) and child takes food from the refrigerator between meals (OR, 0.32; 95% CI, 0.13 to 0.76). CONCLUSIONS: The results of this study suggest that biological and socioeconomic factors are more associated with overweight in Mexican-American preschool-aged children than most of the self-reported child-feeding strategies.

OBJECTIVE: To assess the perception and experience with food insecurity among Latinos living in California, as well as their interpretation of the items included in the Food Security Scale. MATERIAL AND METHODS: A series of four focus groups were carried out among 30 adults of Latin-American descent living in California. The participant's responses were coded by two researchers to identify the main issues, and to compare them for assessing their convergence. RESULTS: The items were well understood and were not perceived as offensive. The conceptual framework was confirmed as a "managed process" with different severity levels. The causes of food insecurity were: unemployment, high cost of some food items, and lack of nutritional information. The demand for nutritional education was constant. CONCLUSION: Interpreting data on food insecurity in Latinos requires proper consideration of their particular perceptions.

OBJETIVO: Estudiar la percepción y la experiencia sobre inseguridad alimentaria entre latinoamericanos de California, así como su interpretación de los insumos incluidos en la Escala de Seguridad Alimentaria. MATERIAL Y MÉTODOS: Entre noviembre y diciembre de 2000, en los condados californianos de Solano y San Joaquín, se efectuaron cuatro grupos focales, con 30 adultos de origen latinoamericano residentes allí. Los comentarios de los participantes fueron codificados por dos investigadores para determinar los temas principales, y fueron confrontados para verificar su convergencia. RESULTADOS: Las preguntas fueron bien comprendidas, no percibiéndose como ofensivas. El marco conceptual se confirmó como "proceso manejado" con diferentes niveles de severidad. Las causas de inseguridad alimentaria identificadas fueron: desempleo, alto costo de algunos alimentos y falta de información nutricional. La necesidad de educación nutricional fue una constante. CONCLUSIONES: Para interpretar datos nacionales de inseguridad alimentaria en latinoamericanos es esencial considerar su percepción particular de ese fenómeno

OBJECTIVE: To examine the relationship of food insecurity to nutrition of Mexican-American preschoolers. DESIGN: Cross-sectional survey of low-income Mexican-American families with children of preschool age (3 to 6 years). Data included food security using the Radimer/ Cornell scale; acculturation; parental education; monthly income; past experience of food insecurity; and child weight, height, and frequency of consuming 57 foods. Weight-for-height z scores (WHZ), height- for-age z (HAZ) scores, and the percentage of overweight (> or = 85th percentile WHZ) were calculated. SUBJECTS/SETTING: A convenience sample of Mexican-American families (n=211) was recruited through Head Start, Healthy Start, Migrant Education, and the Special Supplemental Nutrition Program for Women, Infants, and Children in Tulare, Fresno, Monterey, and Kern counties in California. Statistical analyses Analysis of variance, t tests, Spearman's correlations, and Mantel Haenszel chi2. RESULTS: Limited education, lack of English proficiency, and low income were negatively correlated with food security (r = -0.31 to -0.44, P<.0001). After controlling for acculturation, children in severely food-insecure households were less likely to meet Food Guide Pyramid guidelines than other children (median number of food groups > or = recommended levels [interquartile range]: 2.0 (2.0) vs 3.0 (2.0), P<.006). Although WHZ (mean +/- SD = 1.28 +/- 1.80) and percent overweight (48%, N=19) tended to peak among children from household level food insecure families, no significant differences were found in weight or height status of children by level of food insecurity. APPLICATIONS/CONCLUSIONS: Dietetics professionals working with low-income Hispanic-American families should screen for different levels of food insecurity to determine needs for nutrition education and other services.
