The relation between body weight status and depressive symptoms in the elderly differs according to age and country of origin. The goal of this study was to analyze the cross-sectional and longitudinal relationship between body mass index (BMI), waist circumference (WC) and depressive symptoms in the elderly.
A population-based cohort study of 1,702 elderly individuals (70.6+8.0 years) in Southern Brazil evaluated in 2009/10 and 2013/14 was accessed. The body weight status was assessed using measured data of BMI and WC. The Geriatric Depression Scale (GDS-15) was used to determine depressive symptoms. Logistic regression analysis adjusted for sociodemographic and behavioral variables was performed.
The prevalence of depressive symptoms in 2009/10 was 23.3% (95% CI 20.3-26.6) and the cumulative incidence in the 4-years period was 10.9% (95% CI 8.7-13.6). Elderly people with obesity class II-III and WC in the highest quartile had higher prevalence odds ratio of being depressed than individuals with normal weight or WC in the lower quartile (OR 2.34; 95% CI 1.42-3.87 and OR 1.73; 95% CI 1.13-2.65, respectively). Meanwhile, intermediary values of BMI and WC were associated with a lower prevalence. When evaluating the incidence of depressive symptoms, overweight individuals and those in the second quartile of WC had a lower risk (58% and 57%, respectively), but severely obese individuals had the same risk compared to those with normal BMI/WC.
Severely obese individuals presented a similar incidence of depressive symptoms compared to those with normal BMI/WC, but higher prevalence. Intermediary values of body weight status decrease the risk of depressive symptoms.
老年人的体重状况与抑郁症状之间的关系因年龄和原籍国而异。本研究的目的是分析老年人的体重指数（BMI）、腰围（WC）与抑郁症状之间的横断面和纵向关系。
本研究是一项基于人群的队列研究，纳入了巴西南部的 1702 名老年人（70.6+8.0 岁），这些老年人于 2009/10 年和 2013/14 年接受了评估。体重状况通过 BMI 和 WC 的测量数据进行评估。使用老年抑郁量表（GDS-15）来确定抑郁症状。采用调整了社会人口统计学和行为学变量的逻辑回归分析进行分析。
2009/10 年的抑郁症状患病率为 23.3%（95%CI 20.3-26.6），4 年内的累积发病率为 10.9%（95%CI 8.7-13.6）。与体重正常或 WC 处于较低四分位的个体相比，肥胖 II-III 级和 WC 处于最高四分位的老年人抑郁的患病几率更高（OR 2.34；95%CI 1.42-3.87 和 OR 1.73；95%CI 1.13-2.65）。同时，BMI 和 WC 的中间值与较低的患病率相关。在评估抑郁症状的发生率时，超重个体和 WC 处于第二四分位的个体风险较低（分别为 58%和 57%），但肥胖个体与 BMI/WC 正常的个体风险相同。
与 BMI/WC 正常的个体相比，肥胖个体的抑郁症状发生率相似，但患病率更高。体重状况的中间值降低了抑郁症状的风险。
