This study aimed to determine the prevalence of obesity among medical students and its relationship with their dietary intake and physical activities.
This observational study was carried out on 240 medical students during the clinical phase of their medical course in a private medical school. Their body weight and height were measured, and a standardised questionnaire was used to collect information on their physical activities and dietary intake.
The median body weight of the participants was 59.0 kg (interquartile range: 51.3-66.8), the mean body height was 166.1 cm (standard deviation [SD] 8.5 cm), and the mean body mass index (BMI) was 21.8 kg/m2 (SD 3.4 kg/m2). Based on the World Health Organization BMI cut-offs for the Asian population, 30.1 percent (n is equal to 72) of the students were overweight or obese, with a BMI that was equal to or greater than 23.0 kg/m2. Logistic regression analysis showed that, after controlling for various potential confounders, the only significant risk factors associated with overweight/obesity among these students were: male gender (adjusted odds ratio [OR] 2.1; 95 percent confidence intervals [CI] of 1.1 and 4.1; p is equal to 0.03), Malay ethnic group (adjusted OR 2.4; 95 percent CI 1.0 and 5.7; p is equal to 0.04), Indian ethnic group (adjusted OR 3.6; 95 percent CI 1.5 and 8.9; p is equal to 0.005), and the number of soft drinks consumed per week (adjusted OR 1.3; 95 percent CI 1.0 and 1.5; p is equal to 0.02). Skipping breakfast, the frequency of physical exercise per week, the number of hours of sleep per day, and eating noodles or roti canai (a type of Malaysian pancake) for breakfast were not significant risk factors.
Obesity remains a common problem among medical students in their clinical years.
本研究旨在确定医学生肥胖的患病率及其与饮食摄入和身体活动的关系。
本观察性研究在一所私立医学院的临床阶段对 240 名医学生进行，测量他们的体重和身高，并使用标准化问卷收集他们的身体活动和饮食摄入信息。
参与者的体重中位数为 59.0 公斤（四分位距：51.3-66.8），平均身高为 166.1 厘米（标准差 [SD] 8.5 厘米），平均体重指数（BMI）为 21.8 kg/m2（SD 3.4 kg/m2）。根据世界卫生组织（WHO）针对亚洲人群的 BMI 切点，30.1%（n 等于 72）的学生超重或肥胖，BMI 等于或大于 23.0 kg/m2。逻辑回归分析显示，在校正各种潜在混杂因素后，与这些学生超重/肥胖相关的唯一显著危险因素是：男性（调整后的比值比 [OR] 2.1；95%置信区间 [CI] 1.1-4.1；p 等于 0.03）、马来族（调整后的 OR 2.4；95%CI 1.0-5.7；p 等于 0.04）、印度族（调整后的 OR 3.6；95%CI 1.5-8.9；p 等于 0.005）以及每周饮用软饮料的数量（调整后的 OR 1.3；95%CI 1.0-1.5；p 等于 0.02）。不吃早餐、每周锻炼的频率、每天的睡眠时间以及早餐吃面条或印度煎饼（一种马来西亚煎饼）并不是显著的危险因素。
肥胖仍然是医学生临床阶段的一个常见问题。
