BMI, Screen time, Physical Health, Adolescent


Technology has increased over the past century, from machinery to human health. With that came the modern digital world and the internet. The traditions of playing outside have been replaced with the Internet. With that, the discussion of health-related effects of such, especially those born during immense technological advancement, has also increased. Much lengthy research about the correlation of Physical activity to Screen time exists. Many such face different results, whether there is a correlation or not. The Research Design utilized is Exploratory. The Research Instruments used are Microsoft Forms, Consent Forms, and Microsoft Teams. Population and Sampling Fifteen (15) students were selected from each Grade 7 to 10-grade level of St Mary’s College Quezon City. All informants were chosen through purposive sampling, and all agreed to be respondents by signing the consent form in the survey. Reaching/messaging of participants was done using Microsoft Teams. The average BMI of a JHS student is 22.375, which sits within the scale of 18.5 to 24.9; the average Screen time hours per day of a Junior High School student is 10.58 hours. Grades 7 and 10 coefficient results were remotely the same; however, results for Grade 8 were different because it was shown in the results that there were negative or no correlations at all, meaning that (Higher BMI = Lower Screen Time). In Grade 9, I Was the opposite. Their coefficient results were higher than average (Higher BMI = Higher Screen Time). However, after averaging all the coefficient results, In (Figure no. 15), we can see that the overall coefficient result of the entire JHS of their BMI and ST hours resulted in 0.085504523; it shows that there is a positive to no correlation because the number is closer to zero that it is close to positive 1. The average BMI of the JHS is 22.37, with an average ST hours of 10.58 hours. It is seen that the coefficient result of the entire JHS’s BMI and ST hours is 0.085504523, which shows a slight positive (closer to positive 1) correlation yet a closer digit to 0 which shows that the correlation of BMI and ST of the JGS students shows little positive to no correlation at all.
