研究背景调查老年人肥胖和抑郁症状之间的关系的研究产生了相互矛盾的结果，部分原因是单独使用体重指数（BMI）来衡量老年人的肥胖。BMI的使用未能解释肌肉、脂肪和骨骼的不同比例，并且很少有研究使用其他中心性肥胖指标，如腰臀比（WHR）和腰围（WC）。腰臀比和腰围与老年人抑郁症状的发生相关。对2604名55岁及以上社区老年人的社会情绪特征、自测健康和功能状况、人体测量和老年抑郁量表进行横断面调查（15项，GDS-15）。结果随着BMI的增加，抑郁症状（GDS >= 5）的患病率呈负趋势：低BMI为16.9%，正常体重为14.2%，中到高BMI为12.1%。在控制混杂变量后，中到高BMI（OR，0.77; p = 0.04）相对于正常BMI的相关性具有统计学意义。然而，没有一致的趋势，抑郁症状的患病率和OR的观察增加腰臀比和WC categores.Conclusion我们的研究结果表明，腰臀和周长的措施，中心性肥胖不支持肥胖和抑郁症状的反比关系。BMI与抑郁症状的反比关系可能表明，更大的肌肉质量可以保护更大的生理和功能储备，以防止抑郁症状。版权所有（C）2007约翰威利父子有限公司
Background Studies that investigated the relationship between obesity and depressive symptoms in the elderly have generated conflicting findings, partly because of the use of body mass index (BMI) alone to measure obesity in the elderly. The use of BMI fails to account for varying proportions of muscle, fat and bone, and few studies have used other measures of central obesity, such as waist-hip ratio (WHR) and waist circumference (WC).Objectives We examined whether individually BMI, WHR and WC were consistently associated with depressive symptoms in the elderly.Methods Analysis of cross-sectional data of 2604 community dwelling Chinese elderly aged 55 and above, including socio-emotional characteristics, self-rated health and functional status, anthropometric measurements and Geriatric Depression Scale (15 items, GDS-15).Results There was a negative trend in the prevalence of depressive symptoms (GDS >= 5) across increasing BMI categories: 16.9% in low BMI, 14.2% in normal weight, 12.1% in moderate to high BMI. The associations for moderate to high BMI (OR, 0.77; p = 0.04) relative to normal BMI, were statistically significant after controlling for confounding variables. However, no consistent trends in the prevalence of depressive symptoms and OR'S were observed for increasing WHR and WC categories.Conclusion Our results suggest that waist-hip and circumference measures of central obesity did not support an inverse relationship of obesity and depressive symptoms. An inverse relationship of BMI with depressive symptoms may indicate greater physiologic and functional reserve from greater muscle mass that protects against depressive symptoms.
