DIFFERENCES IN NUTRITIONAL STATUS BASED ON OBESOGENIC BEHAVIOUR AMONG STUDENTS AT SMK BINA PROFESI, BOGOR CITY

Abstract

Adolescent nutritional status is a critical public health concern, as lifestyle shifts and technological advancements have increased vulnerability to overweight and obesity. Obesogenic behaviours, including fast-food intake, regular consumption of carbonated soft-drink, and prolonged sedentary behaviour, further elevate this risk. This study aimed to analyze differences in nutritional status associated with obesogenic behaviour among students at SMK Bina Profesi, Bogor City. A cross-sectional design was employed, with data collected from 39 respondents selected by purposive sampling. Nutritional status was evaluated using Body Mass Index-for-Age (BMI/A), whereas obesogenic behaviour was assessed through a structured questionnaire. Group differences in nutritional status were analyzed using independent t-test.  Results indicated significant differences in nutritional status according to carbonated soft-drink consumption and sedentary behaviour (p<0.05). Participants reporting regular soft-drink consumption and higher sedentary time  exhibited elevated higher BMI/A z-scores. No significant association was observed for fast-food consumption (p>0.05), despite its high prevalence among respondents. Regular nutritional monitoring and targeted health education in schools are recommended to mitigate overweight and obesity risks among adolescents.
