There is a lack of research examining the association between obesity and depressive symptoms in relation to mental health. This study aimed to examine the correlation between Body Roundness Index (BRI) and depressive symptoms in elderly Chinese individuals.
The study sample consisted of 11,842 individuals aged 65 years or older from the 2018 Chinese Longitudinal Health Longevity Survey (CLHLS) database. A multivariate logistic regression analysis was used to investigate how BRI affects the likelihood of experiencing depressive symptoms, with restricted cubic spline (RCS) curves illustrating this impact. BRI values were calculated using a predefined formula for each participant, and depressive status was assessed using the Center for Epidemiologic Studies Depression Scale (CES-D-10).
The mean age of the participants was 83.1 ± 10.9 years. A non-linear relationship was identified between the BRI score and the risk of depressive symptoms. The analysis showed that for BRI scores below 5.17, there was a significant 9% increase in the risk of depressive symptoms for every 1-point decrease in BRI score. Conversely, when the BRI was 5.17 or higher, a decrease in the BRI score did not lead to a significant increase in the risk of depressive symptoms.
The study demonstrated a significant association between BRI and depressive symptoms in elderly Chinese individuals. Furthermore, it was noted that older adults classified as overweight and mildly obese had a lower likelihood of experiencing depressive symptoms and demonstrated improved mental health.
关于肥胖与抑郁症状之间与心理健康相关的关联，缺乏相关研究。本研究旨在探讨中国老年人身体圆润度指数（BRI）与抑郁症状之间的相关性。
研究样本包括来自2018年中国健康与养老追踪调查（CLHLS）数据库的11842名65岁及以上的个体。采用多因素逻辑回归分析来研究BRI如何影响出现抑郁症状的可能性，并用受限立方样条（RCS）曲线来说明这种影响。使用预定义公式为每位参与者计算BRI值，并使用流行病学研究中心抑郁量表（CES-D-10）评估抑郁状态。
参与者的平均年龄为83.1±10.9岁。在BRI得分与抑郁症状风险之间发现了非线性关系。分析表明，对于BRI得分低于5.17的情况，BRI得分每降低1分，抑郁症状风险显著增加9%。相反，当BRI为5.17或更高时，BRI得分降低并未导致抑郁症状风险显著增加。
该研究表明中国老年人的BRI与抑郁症状之间存在显著关联。此外，值得注意的是，被归类为超重和轻度肥胖的老年人出现抑郁症状的可能性较低，且心理健康状况有所改善。
