The Relationship Between Physical Activity And The Incidence Of Obesity In Adolescents

Abstract

Introduction: One of the reasons for the increasing global prevalence of obesity is physical activity. Physical activity is not only important in preventing obesity but can also prevent chronic diseases such as hypertension and cardiovascular disease. Objective: This study aims to determine the relationship between physical activity and the incidence of obesity in adolescents. Methods: This study uses a correlation analytic design using a cross-sectional approach. The sample is teenagers, totaling 59 people in senior high school. The sampling technique uses purposive sampling with the criteria of adolescents who are obese (based on Body Mass Index screening) and adolescents who are not currently sick. Collecting data using the instrument The Physical Activity Questionnaire for Adolescents (PAQ-A) and using a questionnaire for the variable incidence of obesity. Data were analyzed using the test. Spearman's rho. Result: The results showed that there was a relationship between physical activity and the incidence of obesity with p-value = 0.01 <0.05. The value of the correlation coefficient is -0.41, it can be said that the relationship between the two variables is not unidirectional, and the strength of the relationship is sufficient. Most of the physical activities carried out by respondents were light physical activities so it was very possible for obesity to occur. Conclusion: The lower the physical activity, the lower the amount of energy needed so that it will have an impact on body weight or the occurrence of obesity.
