Overweight students had higher diastolic blood pressure (81.6 vs 76.0 mm/Hg, p=0.045), a greater average number of NCDs (1.76 vs 1.05, p=0.017), and a higher prevalence of insufficient sleep (89.7% vs 58.5%, p=0.003) compared to healthy weight students.

Overview

Overweight medical students exhibit gaps in lifestyle-related knowledge and behaviors, higher diastolic blood pressure, and more non-communicable diseases compared to their healthy-weight peers.

Key Points

  • This study aims to assess the knowledge and behaviors of medical students regarding lifestyle modifications in relation to their weight status.
  • Cross-sectional study design conducted among fourth-year medical students at Ain Shams University, Cairo, Egypt.
  • Participants completed a structured survey on lifestyle knowledge and behaviors, with weight and blood pressure measured.
  • Statistical comparisons used t-tests and chi-square tests, with significance set at p<0.05.
  • 60% of students had a healthy weight while 40% were overweight.
  • Overweight students had significantly higher diastolic blood pressure (81.6 mm/Hg vs. 76.0 mm/Hg, p=0.045) and greater average NCDs (1.76 vs. 1.05, p=0.017).
  • Overweight students displayed higher skepticism regarding lifestyle modifications compared to their healthy-weight peers (0.42 vs. -0.18, p=0.022).
