Cardiovascular risk factors in Chinese American children: associations between overweight, acculturation, and physical activity.

INTRODUCTION

Understanding cardiovascular disease (CVD) risk factors among Chinese American children would allow us to target individuals in this group who are at the greatest risk for developing CVD early in life. The purpose of this study is to examine cardiovascular risk factors (increased blood pressure [BP], total cholesterol, low-density lipoproteins, triglycerides, decreased high-density lipoproteins, and increased body mass index [BMI]) in Chinese American children.

METHOD

A cross-sectional design was used. A total number of 65 children, aged 8 to 10 years, and their mothers participated in the study. Measurements of the children's weight, height, BP, blood sample, level of physical fitness, activity level, and dietary intake were collected. Mothers completed questionnaires regarding family history of CVD and level of acculturation.

RESULTS

A low level of physical activity and high paternal BMI were associated with higher systolic BP in the children. A low level of physical activity was also found to be a risk factor for higher LDL and systolic BP in the children. A high birth weight and lower parental acculturation level were risk factors for higher BMI in the children.

DISCUSSION

The findings suggest that a low level of physical activity and high BMI are associated with increased risk of CVD in Chinese American children. The development of culturally appropriate programs that promote an active lifestyle and reduce weight is critical in CVD prevention in Chinese American populations.
