The most recent data indicate that the prevalence of overweight and risk of becoming overweight among Chinese Americans aged 6 to 11 years is 31%. Several physical and psychosocial health consequences are associated with childhood overweight and poor physical fitness, including cardiovascular diseases (CVDs), sleep disorders, type 2 diabetes mellitus, low self-esteem, and social withdrawal. Chinese Americans are at a higher risk of developing CVDs and T2DM than are non-Hispanic whites possibly due to genetic differences in body composition and metabolic responses. Therefore, developing programs that focus on preventing overweight and promoting healthy lifestyles in early childhood is imperative in preventing long-term adverse effects of overweight, especially in Chinese-Americans. A randomized study is proposed to examine feasibility and efficacy of a child-centered and family-focused behavioral intervention on improving health behavior, psychosocial function, anthropometrics, and biochemical indices in Chinese-American children.
The primary aim is to test the effect of a multimedia behavioral intervention on the health behaviors, psychosocial function, and anthropometrics of Chinese-American children, ages 8 and 10.
Aim 1a. Children in the intervention group will report a healthier dietary intake (more vegetable and fiber and lower fat) than will children in the control group at 2 months, 4 months and 6-months post baseline assessment.
Aim 1b. Children in the intervention group will report being more active than will children in the control group at 2 months, 4 months and 6-months post baseline assessment.
Aim 1c. Children in the intervention group will report a significantly higher self-efficacy in relation to nutrition and physical activity than will children in the control group at 2 months, 4 months and 6-months post baseline assessment.
Aim 1d. Children in the intervention group will report significantly better coping than will children in the control group at 2 months, 4 months and 6-months post baseline assessment.
Aim 1e. Children in the intervention group will report a greater decrease in BMI than will children in the control group at 6-months post baseline assessment.
Aim 1f. Children in the intervention group will experience a greater decrease in fat mass than will children in the control group at 6-months post baseline assessment.
The secondary aim is to examine the effect of the multimedia behavioral intervention on biochemical indices of health in Chinese-American children, ages 8 and 10.
Aim 2a. Children in the intervention group will experience an increase in insulin sensitivity vs. children in the control group at 6-months post baseline assessment.
Aim 2b. Children in the intervention group will experience an improvement in cholesterol, high-density lipoproteins (HDLs), low-density lipoproteins (LDLs), and triglycerides (TGs) vs. children in the control group at 6- months post baseline assessment.
