Obesity has emerged as a major health problem. Prevalence is increasing hugely. Various etiological factors had been identified as potential causes of obesity. There is an increasing need to study different determinants of obesity especially the physical activity and eating habits. Future doctors considered as role models in community. Doctor wellbeing’s does not just affect them it has robust impact on their surroundings. More knowledge about determinants of obesity among medical students may shed light concerning obesity prevention and control. Therefore, the aim of this study was to determine the relationships between physical activity, eating patterns, and obesity among medical students. This was a cross sectional study conducted among 216 medical students at Al-Neelain University selected by stratified random sampling. Data were collected by self-administered questionnaire, which included background data. International physical activity questionnaire (IPAQ) was used to determine physical activity level and the three factors eating questionnaire Revised 18 (TFEQ-r18) was used to determine eating behavior. Also, anthropometric measurements were performed for each participant. Data were analyzed using SPSS version 23 program. Descriptive data were presented as means ± SD and percentages. The relationships between BMI and physical activity levels and between BMI and eating pattern were analysed using non parametric test. P value < 0.05 was considered significant. . The prevalence of obesity among students was 6.5% and overweight was 22.2%. The study showed that 44.9% of medical students had low activity level while 32% of students had moderate activity level and 23.1% had high physical activity level. There was no significant relationship between physical activity and body mass index (BMI) in this study. The common eating pattern among students was controlled eating (45.8%). There was significant relationship between eating behaviors and BMI (P = 0.01). The study revealed eating habits has stronger impact on BMI than physical activity. Disturbing figures regarding overweight and low physical activity among medical students, identified in this study, encourages implementation of health programs. Emphasize on importance and benefits of physical activity and eating habits in medical curricula.

苏丹医学生体力活动、饮食行为与肥胖的相关性 苏丹

肥胖已成为一个主要的健康问题。患病率正在急剧增加。多种病因已被确定为肥胖的潜在原因。人们越来越需要研究肥胖的不同决定因素，特别是体力活动和饮食习惯。未来的医生被视为社区的榜样。医生的健康不仅影响他们自己，还对他们的周围环境产生巨大影响。更多地了解医学生肥胖的决定因素可能有助于肥胖的预防和控制。因此，本研究的目的是确定医学生身体活动、饮食模式和肥胖之间的关系。这是一项横断面研究，对象是 Al-Neelain 大学的 216 名医学生，通过分层随机抽样进行选择。数据通过自填问卷收集，其中包括背景数据。国际身体活动问卷（IPAQ）用于确定身体活动水平，三因素饮食问卷修订版18（TFEQ-r18）用于确定饮食行为。此外，还对每位参与者进行了人体测量。使用 SPSS 23 版程序分析数据。描述性数据以平均值±标准差和百分比的形式呈现。使用非参数检验分析BMI与体力活动水平以及BMI与饮食模式之间的关系。P值<0.05被认为是显着的。。学生肥胖率为6.5%，超重率为22.2%。研究显示，44.9%的医学生活动水平较低，32%的学生活动水平中等，23.1%的学生活动水平较高。本研究中体力活动与体重指数（BMI）之间没有显着关系。学生普遍的饮食模式是控制饮食（45.8%）。饮食行为与BMI之间存在显着相关性（P = 0.01）。研究显示，饮食习惯对体重指数的影响比体力活动更大。本研究中发现的有关医学生超重和体力活动不足的令人不安的数据鼓励实施健康计划。强调医学课程中身体活动和饮食习惯的重要性和益处。
