Physical Activity and Television Viewing Linked to Body Mass Index among Philippine High School Students: Signaling of an Emerging Epidemic of Obesity?

Abstract

The major purpose of this study was to determine whether body mass index (BMI) was associated with reports of vigorous physical activity and television viewing among a sample of more than 3,000 Philippine high school students. In addition, the International Task Force on Obesity's new cutoff points to these adolescents' self-reports were applied to calculations of BMI based on self-reported height and weight in order to determine the prevalence of overweight and obesity among this sample of Filipino adolescents. Results showed that Filipino boys and girls who were the most frequent participants in vigorous physical activity (3 or more times a week) had significantly lower BMI when compared to those who were physically active less frequently. Conversely, Filipino boys and girls who viewed five or more hours of television during an average school day had significantly higher BMI than those who watched less television. The percentage of Philippine students in this study above the international cut offs for overweight (6.5 percent of boys and 5.7 percent of girls) and obesity (1.6 percent of boys and 1.8 percent of girls) was considerably lower than what has been found in studies of youth in developed Western nations. However, the adopting of Western lifestyle habits, including increased recreational inactivity (e.g., television viewing, video games, and surfing the Internet) and decreased participation in vigorous physical activity, could signal an emerging epidemic in this developing nation.
