Prevalence estimates of overweight in Head Start preschoolers.

This study estimates prevalence of overweight and at risk of overweight among low-income predominately non-Hispanic Black Head Start Mississippi preschoolers. A two-stage stratified probability design produced a representative sample of 1,250 preschoolers aged 3 to 5 years. Height, weight, age, gender, and race data were obtained. The prevalence of overweight (20.6%) and at risk of overweight (17.9%) combined was 38.5%. Moreover, highest rates were found in boys, non-Hispanic Blacks, and 5-year-olds. The prevalence of overweight in Mississippi Head Start children exceeds national averages, reinforcing the need for early-childhood health promotion and prevention.
