Midlife vulnerability and food insecurity: Findings from low-income adults in the US National Health Interview Survey.

Background: Food insecurity, limited access to adequate food, in adulthood is associated with poor health outcomes that suggest a pattern of accelerated aging. However, little is known about factors that impact food insecurity in midlife which in turn could help to identify potential pathways of accelerated aging.

Methods: Low-income adults (n = 17,866; 2014 National Health Interview Survey), ages 18 to 84, completed a 10-item food security module and answered questions regarding health challenges (chronic conditions and functional limitations) and financial worry.

Influence of pre-schooler and parent nutrition education on carotenoid levels of Mexican-heritage children.

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.

A three-year multifaceted intervention to prevent obesity in children of Mexican-heritage.

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.

Prevalence and predictors of overweight and obesity among Cameroonian women in a national survey and relationships with waist circumference and inflammation in Yaoundé and Douala.

Information on the distribution and predictors of obesity in Africa is needed to identify populations at risk and explore intervention options. Our objectives were to (a) examine the prevalence and geographic distribution of overweight and obesity among Cameroonian women; (b) evaluate change in anthropometric indicators among urban women between 2009 and 2012; (c) examine associations between household and individual characteristics and overweight and obesity; and (d) examine relationships between body mass index (BMI), abdominal obesity, and inflammation. We analysed data from a nationally representative survey conducted in 3 geographic strata (North, South, and Yaoundé/Douala) in Cameroon in 2009 and a survey in Yaoundé/Douala in 2012.

Attitudes and Social Norms Are Related to Attendance at Childhood Obesity Prevention Classes in a Rural Mexican-Heritage Community.

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.

Purchases Made with a Fruit and Vegetable Voucher in a Rural Mexican-Heritage Community.

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.

Healthy Lifestyle Fitness Camp: A Summer Approach to Prevent Obesity in Low-Income Youth.

Objective: To examine the effect of participation in a summer camp focused on nutrition and fitness among low-income youth.

Methods: In 2011-2012, overweight and obese youth (n = 126) from Fresno, CA participated in a free 6-week summer program, Healthy Lifestyle Fitness Camp (HLFC), which included 3 h/wk of nutrition education provided by University of California CalFresh and 3 hours of daily physical activity through Fresno Parks and Recreation. The researchers used repeated-measures ANOVA to examine changes in weight, waist circumference, and waist-to-height ratio (WHtR) between HLFC and the comparison group (n = 29).

Relative validity of a tool to measure food acculturation in children of Mexican descent.

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.

Assessing Child Obesity and Physical Activity in a Hard-to-Reach Population in California's Central Valley, 2012-2013.

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.

Adaptation of a culturally relevant nutrition and physical activity program for low-income, Mexican-origin parents with young children.

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.

Food Resource Management Education With SNAP Participation Improves Food Security.

Objective: To determine the influence of Supplemental Nutrition Assistance Program (SNAP) and participant demographics on nutrition education outcomes.

Methods: At program enrollment (pre) and 1 month later (post), a statewide convenience sample of adults, who participated in the Plan, Shop, Save, and Cook program, completed a 7-item questionnaire to evaluate change in resource management skills (RMS) and running out of food before the end of the month.

Results: Percent of participants (n = 3,744) who reported behavioral improvements in RMS ranged from 38.

Practice paper of the Academy of Nutrition and Dietetics abstract: nutrition and lifestyle for a healthy pregnancy outcome.

It is the position of the Academy of Nutrition and Dietetics that women of childbearing age should adopt a lifestyle optimizing health and reducing risk of birth defects, suboptimal fetal development, and chronic health problems in both mother and child.Components leading to healthy pregnancy outcome include healthy pre-pregnancy weight, appropriate weight gain and physical activity during pregnancy, consumption of a wide variety of foods, appropriate vitamin and mineral supplementation, avoidance of alcohol and other harmful substances, and safe food handling. Nutrition assessment needs to encompass changes in anthropometric,biochemical, and clinical indicators throughout pregnancy.

Correlates of food patterns in young Latino children at high risk of obesity.

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.

Sweetened food purchases and indulgent feeding are associated with increased toddler anthropometry.

Objective: To explore the role of feeding practices and food purchases in toddler dietary intake and anthropometry.

Methods: A convenience sample of Latino mother and toddler pairs were interviewed at baseline and at 6-month follow-up. Data on feeding practices, toddler dietary intake, anthropometry, and food purchases were collected using the Toddler-Feeding Questionnaire; 24-hour recalls; measurements of weight, height, and/or length; and food purchase receipts.

Background: Overweight and obese children are likely to develop serious health problems. Among children in the U.S.

Child feeding practices and overweight status among Mexican immigrant families.

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.

Development and use of an evaluation tool for taste-testing activities by school-aged children.

We describe the development and application of a teacher-administered tool for routine program evaluation of food-tasting activities among low-income children and adolescents in a classroom or afterschool setting. This six-item evaluation tool is intended to capture student willingness to try new foods and ask for them at home. Phase 1 involved one-on-one interviews to determine the feasibility of the taste test tool among nine elementary school teachers in 2009 (168 students) and a validation pilot study in 2010 among 114 school-aged students participating in a University of California Supplemental Nutrition Assistance Program Nutrition Education (UC SNAP-Ed) summer program.

Acculturation, physical activity and television viewing in Hispanic women: findings from the 2005 California Women's Health Survey.

Objective: To assess the relationship of acculturation with physical activity and sedentary behaviours among Hispanic women in California.

Design: Data from the 2005 California Women's Health Survey (CWHS) - a cross-sectional telephonic survey of health indicators and health-related behaviours and attitudes - were used.

Setting: Using a random-digit dialling process, data were collected monthly from January to December 2005.

Validation of an instrument to assess toddler feeding practices of Latino mothers.

This paper describes qualitative and quantitative aspects of testing a 34-item Toddler-Feeding Questionnaire (TFQ), designed for use in Latino families, and the associations between feeding practices and toddler dietary outcomes. Qualitative methods included review by an expert panel for content validity and cognitive testing of the tool to assess face validity. Quantitative analyses included use of exploratory factor analysis for construct validity; Pearson's correlations for test-retest reliability; Cronbach's alpha (α) for internal reliability; and multivariate regression for investigating relationships between feeding practices and toddler diet and anthropometry.

Convergent validity of a digital image-based food record to assess food group intake in youth.

Current methods to assess the dietary behavior of youth have many limitations that reduce accuracy. Previous research has examined use of food images to assess nutrient intake. The objectives for this study are to validate the use of a novel digital image-based food record (DIFR) method to assess food group intake in youth and examine inter-analyst reliability.

Toddler-feeding practices among Mexican American mothers. A qualitative study.

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.

Impact of vaccination against chicken Newcastle disease on food intake and food security in rural households in Tanzania.

Background: Small-scale poultry production has the potential to increase animal-source food consumption, improve household income, and reduce food insecurity.

Objective: To assess the impact of a chicken Newcastle disease vaccination program on consumption of chicken and eggs among women and children, income, and food insecurity in rural Tanzanian households.

Methods: Comparisons were made between households from three project villages, which participated in a Newcastle disease vaccination program for chickens, and three control villages, which did not participate.

Using qualitative methods to improve questionnaires for Spanish speakers: assessing face validity of a food behavior checklist.

Development of outcome measures relevant to health nutrition behaviors requires a rigorous process of testing and revision. Whereas researchers often report performance of quantitative data collection to assess questionnaire validity and reliability, qualitative testing procedures are often overlooked. This report outlines a procedure for assessing face validity of a Spanish-language dietary assessment tool.
