Predictors of Accurate Maternal Perception of Their Preschool Child’s Weight Status Among Hispanic WIC Participants

The goal of this study was to assess the accuracy of maternal perceptions of their children's weight status. Almost all mothers in the study classified their overweight or obese child as being about the right weight. As a result, they might not see obesity interventions as relevant to their families. researchers concluded that parents need education in two areas: (1) how to identify whether their children are overweight or obese and (2) the consequences of obesity.


WIC and the Battle Against Childhood Overweight

The number of children at risk of being overweight has grown during the past two decades, as has the number of young children whose families participate in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). Are these increases connected? According to the author, the answer appears to be no. However, being from a low-income family;especially a low-income, Mexican-American family;did raise the probability of a child's risk of being overweight. This brief examines trends in the relationship between WIC participation and weight status, by updating the results of Food and Nutrition Assistance Programs and Obesity: 1976-2002 (USDA/ERS, Economic Research Report No. 48), to include data from the 2003-2006 National Health and Nutrition Examination Survey (NHANES).


Early Onset of Overweight and Obesity Among Low-Income 1- to 5-year-olds in New York City

The purposes of this study were to assess prevalence of overweight and obesity among urban 1- to 5-year-olds and estimate risk by age and gender. The results showed that significant increases in overweight and obesity occurred between ages 1 and 3. And, more than half of the urban children were overweight or obese by age 5. Furthermore, boys were more likely to be obese than were girls. Based on their findings, the researchers recommended that obesity prevention interventions should be targeted to children between the ages of 1 and 3.


Strategies which Aim to Positively Impact on Weight, Physical Activity, Diet, and Sedentary Behaviours in Children from 0 to 5 Years: A Systematic Review of the Literature

Researchers conducted a systematic review of literature on obesity prevention and other healthy eating and physical activity interventions targeted at children ages 0 to 5 years old. While there was variety in study design, most interventions were multifaceted and showed at least some level of effectiveness for obesity prevention behavior in this population.


Food and Nutrition Assistance Programs and Obesity: 1976-2002

The authors analyzed multiple years of cross-sectional data to understand trends in the relationship between food assistance program participation and body weight. High rates of overweight and obesity among low-income populations in the US had raised questions about whether federal food and nutrition assistance programs contributed to the problem. To examine this possibility, the study investigated (1) the extent to which overweight and obesity had increased over time for food and nutrition assistance recipients (focusing on the Food Stamp Program and WIC) and (2) the degree to which increases might simply have mirrored national trends in overweight and obesity.


Could Behavioral Economics Help Improve Diet Quality for Nutrition Assistance Program Participants?

As obesity has come to the forefront of public health concerns, there is growing interest in finding ways to guide consumers’ food choices to be more beneficial for their long-term health. About one in five Americans participates in at least one nutrition assistance program sponsored by the USDA. The researchers used behavioral economics, food marketing, and psychology to identify possible options for improving the diets and health of participants in the Food Stamp Program, the WIC Program, and the National School Lunch and School Breakfast programs.


Using Focus Group Results to Inform Preschool Childhood Obesity Prevention Programming

The purpose of this study was to help determine material for developing a childhood obesity prevention program for multi-ethnic parents. researchers concluded that intervention components should focus on parent self-efficacy and incorporate themes specific for ethnic groups. The authors also suggested that there was a need for culturally sensitive health and nutrition information.
