Obesity Prevalence in Low-Income Preschool Children in Oklahoma

The purposes of this study were (1) to determine the prevalence of overweight and obesity in low-income preschool children in Oklahoma, enrolled in the WIC Program, and (2) to identify potential racial and ethnic disparities. American Indians and Hispanic children had the highest obesity rates. The researchers pointed out the necessity to explore targeting interventions at these high-risk groups.


Evidence of the Adoption and Implementation of a Statewide Childhood Obesity Prevention Initiative in the New York State WIC Program: The “NY Fit WIC” Process Evaluation

The purpose of this study was to determine the extent to which NY Fit WIC, a childhood obesity prevention initiative, was adopted and implemented by the New York State WIC Program. All agencies carried out a variety of activities. The researchers suggested that given a very strong adoption of the program, an outcome evaluation was warranted, to help determine behavior change.


Effects of Breastfeeding and Low Sugar-Sweetened-Beverage (SSB) Intake on Obesity Prevalence in Hispanic Toddlers

The purpose of this study was to determine the effects of breastfeeding and sugar-sweetened- beverage (SSB) consumption on the prevalence of overweight and obesity in Hispanic toddlers enrolled in the WIC Program. Results indicated that breastfeeding for 1 year or longer and low SSB consumption during the toddler years could significantly reduce prevalence of obesity in Hispanic toddlers.


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.
