This clinical trial tests the effectiveness of a Healthy Parents and Children Enhancement (H-PACE) program for improving lifestyle behaviors among children. Proper nutrition and physical activity (PA) are essential parts of overall health. Together, they can decrease the risk of developing obesity as well as related diseases such as diabetes, heart disease, stroke, and several types of cancer. To address the prevalence of obesity and related diseases, programs focusing on increasing opportunities for active living and healthy eating are necessary. Multi-component school-based obesity prevention programs have demonstrated increases in PA and improvement in dietary habits; however, most afterschool programs are short term; evidence is needed to confirm long-term effects. Moreover, programs that involve parents have shown to be more successful in helping children choose healthier behaviors. Unfortunately, due to technological advancement, opportunities for children to be active in schools have become more limited in modern society. H-PACE program is based on the national childhood obesity prevention campaign designed to help families, schools, communities, and physicians to raise awareness of nutritional and PA daily guidelines. The H-PACE will encourage daily lifestyle behaviors (five or more servings of fruits and vegetables, two hours or less of recreational screen time, one hour of PA, zero sugary drinks, ten hours of sleep) that impact childhood obesity. This trial is being done to determine whether participating in the H-PACE program may help improve lifestyle behaviors among children.
