Sedentary behaviour such as moderate – vigorous intensity physical activity less than 2 hours a day and screen time more than 2 hours a day may cause childhood obesity. The goal of this research is to analyze the correlation between physical activity and screen time with BMI in primary school students. This is a quantitative analytical research using cross sectional design study. The population are136 5 th grade students. Slovins formula is used to count the sample of this research. 35 students are used to test the validity of the questionnaire while the rest (101 students) are used as sample.
