A twelve-week controlled intervention trial was carried out to evaluate the effects of combined physical activity and dietary intervention on obesity and metabolic risk factors among employees of Universiti Putra Malaysia. Participants consisted of adults aged 25-55 years with no reported chronic diseases but with abdominal obesity. They were assigned to either a combined physical activity and dietary intervention group or a control group. The final sample consisted of 56 participants, with an equal number of 28 for each study group. No significant group effect was observed for any variable except for hip circumference (HC) and fasting plasma glucose (FPG). There was a significant increase in HC (p=0.007) and reduction in FPG (p=0.02) in the intervention group compared to the control group. In the intervention group, HC (p=0.002), triglycerides (TG) (p=0.0001), total cholesterol (TC) (p=0.0001), LDL cholesterol (LDLC) (p=0.0001) and FPG (p=0.005) were significantly reduced, while waist circumference (WC) (p=0.025) and the waist-to-hip ratio (WHR) (p=0.027) were significantly reduced in the control group. No significant change in steps/day or calorie intake'was observed in either group. Taken together, these data indicate that the combined physical activity and dietary intervention was not effective at improving diet or physical activity level. However, the intervention was effective in improving FPG among participants with abdominal obesity. The significant increase in HC in the interventions group warrants further study. These findings will be useful to further improve group-based intervention for the prevention and management of obesity.
开展了一项为期12周的对照干预试验，以评估体育活动与饮食干预相结合对马来西亚博特拉大学员工肥胖及代谢风险因素的影响。参与者为年龄在25 - 55岁之间、无慢性疾病报告但有腹部肥胖问题的成年人。他们被分配到体育活动与饮食联合干预组或对照组。最终样本由56名参与者组成，每个研究组各28名。除臀围（HC）和空腹血糖（FPG）外，未观察到任何变量有显著的组间效应。与对照组相比，干预组的HC显著增加（p = 0.007），FPG降低（p = 0.02）。在干预组中，HC（p = 0.002）、甘油三酯（TG）（p = 0.0001）、总胆固醇（TC）（p = 0.0001）、低密度脂蛋白胆固醇（LDLC）（p = 0.0001）和FPG（p = 0.005）显著降低，而对照组的腰围（WC）（p = 0.025）和腰臀比（WHR）（p = 0.027）显著降低。两组的每日步数或卡路里摄入量均未观察到显著变化。综上所述，这些数据表明体育活动与饮食联合干预在改善饮食或身体活动水平方面无效。然而，该干预对改善腹部肥胖参与者的FPG有效。干预组HC的显著增加值得进一步研究。这些发现将有助于进一步改进基于群体的肥胖预防和管理干预措施。
