Abstract

Background

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.

Methods

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).

Results

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.

Conclusion

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.

中国老年人BRI与抑郁症状的关系：一项基于clhls的研究

背景：目前缺乏关于肥胖和抑郁症状与心理健康之间关系的研究。本研究旨在探讨中国老年人身体圆度指数（BRI）与抑郁症状的相关性。方法：研究样本包括来自2018年中国纵向健康长寿调查（CLHLS）数据库的11,842名65岁及以上的个体。采用多变量logistic回归分析来研究BRI如何影响经历抑郁症状的可能性，限制三次样条（RCS）曲线说明了这种影响。使用预定义的公式计算每个参与者的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。结果：参与者平均年龄为83.1±10.9岁。BRI评分与抑郁症状风险之间存在非线性关系。分析表明，对于BRI得分低于5.17的人，BRI得分每降低1分，抑郁症状的风险就会显著增加9%。相反，当BRI为5.17或更高时，BRI得分的降低并不会导致抑郁症状风险的显着增加。结论：该研究表明BRI与中国老年人抑郁症状之间存在显著关联。此外，研究还指出，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，心理健康状况有所改善。

期刊介绍： The International Journal of Methods in Psychiatric Research (MPR) publishes high-standard original research of a technical, methodological, experimental and clinical nature, contributing to the theory, methodology, practice and evaluation of mental and behavioural disorders. The journal targets in particular detailed methodological and design papers from major national and international multicentre studies. There is a close working relationship with the US National Institute of Mental Health, the World Health Organisation (WHO) Diagnostic Instruments Committees, as well as several other European and international organisations. MPR aims to publish rapidly articles of highest methodological quality in such areas as epidemiology, biostatistics, generics, psychopharmacology, psychology and the neurosciences. Articles informing about innovative and critical methodological, statistical and clinical issues, including nosology, can be submitted as regular papers and brief reports. Reviews are only occasionally accepted. MPR seeks to monitor, discuss, influence and improve the standards of mental health and behavioral neuroscience research by providing a platform for rapid publication of outstanding contributions. As a quarterly journal MPR is a major source of information and ideas and is an important medium for students, clinicians and researchers in psychiatry, clinical psychology, epidemiology and the allied disciplines in the mental health field.
