Insights
Obesity affects 30.7% of low-income Oklahoma preschoolers. American Indian and Hispanic children show higher obesity rates, indicating a need for targeted interventions.
Area of Science:
- Pediatric Nutrition
- Public Health
- Health Disparities
Background:
- Childhood obesity is a significant public health concern.
- Low-income preschool children are particularly vulnerable to nutritional challenges.
- Understanding race/ethnic disparities in obesity is crucial for effective interventions.
Purpose of the Study:
- To determine the prevalence of overweight and obesity in low-income preschool children in Oklahoma.
- To identify potential race/ethnic disparities in obesity rates among these children.
Main Methods:
- Utilized data from 39,151 children aged 2-4 years enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in Oklahoma during 2009.
- Calculated body mass index (BMI) percentiles using child's height, weight, sex, and age.
Main Results:
- In 2009, 30.7% of Oklahoma WIC children were overweight, with 13.7% classified as obese.
- Significant race/ethnic disparities were observed, particularly for obesity: American Indian (18.8%) and Hispanic (17.2%) children had higher prevalence compared to non-Hispanic whites (11.8%).
- African American children showed lower obesity prevalence (OR = 0.9).
Conclusions:
- Obesity rates are disproportionately high among American Indian and Hispanic low-income preschool children in Oklahoma.
- Interventions specifically targeting these high-risk racial/ethnic groups are warranted to address these disparities.
Objective:
To determine the prevalence of overweight and obesity in low-income preschool children in Oklahoma and to identify potential race/ethnic disparities.
Methods:
Subjects included 39,151 children aged 2 to 4 years who participated in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in 2009. Body mass index percentiles were calculated from the child's height, weight, sex, and age.
Results:
In 2009, 30.7% of Oklahoma's children in WIC were overweight, including 13.7% obese. Disparities by race/ethnicity were greatest for obese children: prevalence was 18.8% for American Indians (odds ratio [OR] = 1.8, confidence interval [CI] = 1.54-2.03) and 17.2% for Hispanics (OR = 1.6, CI = 1.52-1.73) compared with 11.8% for non-Hispanic whites, whereas African Americans were less obese (OR = 0.9, CI = 0.79-0.98).
Conclusion:
Obesity rates in low-income Oklahoma children are highest among American Indians and Hispanic children. Interventions aimed at these high-risk groups need to be explored.
