Parents' income has influence on levels of physical activity and sedentary behaviour of junior high school student

This study aims to determine physical activity (PA level) and sedentary behavior (SB level) in students with various parents' income levels. This study used a cross-sectional design. The subjects used in this study were 900 students from 10 schools and ten cities in East Java, Indonesia. Data on students' parents' income were grouped into five categories based on their income level (very low: n = 360; low: n = 231; medium: n = 123; high: n = 79; very high: n = 107). The research instruments used were the Children’s Physical Activity Questionnaire (CPAQ) to measure the level of physical activity (PA level) and the Adolescent Sedentary Activity Questionnaire (ASAQ) to measure the level of sedentary behavior (SB level). The results of the Mann-Whitney statistical test showed significant differences in PA level and SB level between the very low-income group of parents and the low, medium, high, and very high-income groups (p<0.05). In conclusion, the higher the level of parental income, the better the students' physical activity, and the lower their sedentary behaviour.
