Food Security and Nutritional Outcomes of Preschool-Age Mexican-American Children

Lucia L. Kaiser; Cathi Lamp; Margaret Johns; Jeanette Sutherlin; Janice O. Harwood; Hugo Melgar-Quinonez

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, Spearmans 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.

Acculturation of Mexican-American mothers influences child feeding strategies

Lucia L. Kaiser; Hugo Melgar-Quinonez; Cathi Lamp; Margaret Johns; Janice O. Harwood

OBJECTIVE The purpose of this study was to examine the influence of maternal acculturation level on child feeding strategies and anthropometry in preschoolers from low-income Mexican-American families. DESIGN/SUBJECTS Data are from a cross-sectional survey of 238 low-income Mexican-American families with preschool children living in California during 1998. Interviewers collected data from the mothers on child-feeding practices and weighed and measured the children in their homes. STATISTICAL ANALYSES Spearmans correlation coefficients, analysis of variance, and chi 2 were used to examine the relationship pf maternal acculturation level with feeding strategies and anthropometric measurements. RESULTS Compared with more acculturated mothers, less acculturated mothers tend to offer alternative foods more often when their children refuse to eat. More acculturated women are less likely to view bribes, threats, and punishments as effective strategies and are more likely to give vitamins than less acculturated mothers. Maternal acculturation is not associated with differences in weight-for-height z-scores, height-for-age, or body mass index of the children. Triceps skinfold thickness are larger in children of more acculturated mothers than in children of less acculturated women. APPLICATIONS/CONCLUSIONS Dietitians should consider differences in child feeding practices due to acculturation among Mexican-Americans. Successful strategies to encourage consumption of nutritious traditional foods and to transition from child-led snacking to more structured meals should be part of nutrition education 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 childrens food consumption and feeding practices. Statistical tests included t tests and ANCOVA. SETTING Rural communities in Californias 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. Mothers acculturation level was positively related to childrens 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.

Improving the Quality of Data From EFNEP Participants With Low Literacy Skills: A Participant-driven Model

Marilyn S. Townsend; Chutima Ganthavorn; Marisa Neelon; Susan Donohue; Margaret Johns

Low literacy skills and poor evaluation tool readability combined with the stresses of the classroom environment create a high cognitive load for Expanded Food and Nutrition Education Program (EFNEP) participants, resulting in lower quality data. The authors advocate for 9 strategies for improving the participant cognitive load for the evaluation process using the EFNEP Family Record as an example.

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.
