    Medical education and awareness of serum lipid levels led to healthier habits in students. This resulted in a significant decrease in cholesterol, a key factor for coronary heart disease risk.

    Area of Science:

    • Preventive Medicine
    • Cardiovascular Health
    • Medical Education

    Background:

    • Serum lipid levels are critical indicators of cardiovascular disease risk.
    • Understanding and modifying lifestyle factors can impact lipid profiles.
    • Medical students provide a unique cohort for studying health behavior changes.

    Purpose of the Study:

    • To evaluate changes in serum lipids (cholesterol and triglycerides) among medical students over four years.
    • To investigate the influence of medical education and knowledge of initial lipid values on students' lifestyle modifications.
    • To determine the impact of dietary and exercise habit changes on serum lipid levels in this population.

    Main Methods:

    • Longitudinal analysis of serum cholesterol and triglyceride levels in 108 medical students from freshman to senior year.

  • Utilized a self-administered questionnaire to assess changes in diet and exercise habits.
  • Correlated lifestyle changes with alterations in lipid profiles and body weight.

    • Main Results:

    • A statistically significant decrease in mean serum cholesterol levels (-10 mg/dL) was observed.
    • Mean serum triglyceride and body weight showed non-significant increases.
    • Students with initially abnormal lipid values were more likely to modify their diets.
    • Combined diet and exercise changes yielded the greatest reduction in lipid values, though not solely attributable to habit changes.

    Conclusions:

    • Medical school education and awareness of lipid levels can motivate students to adopt healthier lifestyles.
    • Early detection and intervention strategies may positively influence coronary heart disease risk factors in young adults.
    • Lifestyle modifications, particularly combined dietary and exercise changes, show potential for improving lipid profiles.
