General Nutrition Knowledge and Physical Fitness as Predictors of Body Mass Index (BMI) Among Senior High School Students

Aprilyn Galela | Gelsa G. Dragon

Discipline: Education

 

Abstract:

The primary purpose of this study is to examine how general nutrition knowledge and physical fitness influence body mass index (BMI) among senior high school students. A descriptive correlational design was used, and stratified random sampling ensured fair representation of the participants. Data were gathered from selected senior high schools in Bayugan City using adapted and researcher-developed questionnaires validated by experts. The findings revealed that general nutrition knowledge is high and is often observed. Additionally, the level of physical fitness is fair, indicating moderate development. Moreover, the distribution of Body Mass Index among senior high school students reveals a varied nutritional profile within the population. Furthermore, general nutrition knowledge shows no significant relationship with body mass index; however, physical fitness does. Ultimately, when combined, general nutrition knowledge and physical fitness do not significantly influence body mass index in isolation.
