Abstract

Objectives – Realizing the sedentary lifestyle of medical students the present study is conducted to
assess their physical activity by pedometer, to determine the gender difference, to compare weekdays’
activity with weekend, and to find the effect of BMI on physical activity. Methods – Physical activity of
30 students was recorded by pedometer for seven days. Mean number of steps per day were calculated
for the whole group, boys and the girls. Comparison of groups was done by student t test and p value
of < 0.05 was considered significant. Pearson’s correlation coefficient was used to determine the
relationship between the pedometer determined physical activity and height, weight and BMI. ResultsThe mean age of the subjects was 18.9 + 0.8 years. Average number of steps per day was 8039 + 2533.
The mean number of steps per day taken by the boys were significantly more than the girls (9258 +
2736 vs 6821 + 1621, p=0.01). The average number of steps taken by the subjects were significantly
more during weekdays than weekend (8279 + 2521 vs 7440 + 3150, p= 0.04). Weight and BMI did
not correlate with the number of steps per day, while height had positive correlation. ConclusionsStudents have suboptimal physical activity; the boys are physically more active than girls; students are
more active during week days as compared to weekend; and there was no correlation of weight & BMI
with physical activity
