Association of physical activity, central adiposity, and fast-food consumption with 2-hour plasma glucose in adolescent girls at a boarding school in East Java

Introduction

Type 2 diabetes mellitus (T2DM) is increasingly reported among adolescents and is associated with modifiable factors such as central obesity, physical inactivity, and frequent intake of fast food. Boarding schools offer a structured environment to assess these behaviours. Aim of the study: To examine the correlation between physical activity, central adiposity, fast-food consumption, and 2-hour plasma glucose (2-hPG) in adolescent girls at a boarding school. Material and methods: A cross-sectional study was conducted among 127 adolescent girls in East Java. Physical activity was assessed using the Physical Activity Questionnaire for Adolescents. Adiposity was measured using body mass index (BMI) and waist circumference. Fast-food consumption frequency was recorded through a structured questionnaire. Blood glucose was measured using a 2-hPG test after oral glucose intake. Urine dipstick screening was also performed.
