Mental health problems, especially depressive symptoms, are becoming increasingly prominent, posing a significant risk to public health. Changes in the body mass index (BMI) may impact an individual's mental health, however, the relationship between BMI and depressive symptoms is unclear. The purpose of this study was to investigate the association between BMI and depressive symptoms.
Using a multi-stage sampling method, 10,686 adults in Longgang District, Shenzhen City, Guangdong Province, China, were selected for participation in this study. Surveys were distributed in 2020 and 2021 to measure participant demographic data and health. Binary logistic regression, restricted cubic spline regression, and subgroup analyses were performed to explore the relationship between BMI and depressive symptoms.
The results showed a U-shaped relationship between BMI and depression. Both obesity and underweight increased the risk of depression among the participants, especially in subgroups of participants who were young, highly educated, single and employed.
These findings suggest that adults should try to maintain a normal body weight as a way to prevent depression and maintain their physical and mental health.
心理健康问题，尤其是抑郁症状，正变得日益突出，对公众健康构成重大风险。体重指数（BMI）的变化可能会影响个体的心理健康，然而，BMI与抑郁症状之间的关系尚不清楚。本研究的目的是调查BMI与抑郁症状之间的关联。
采用多阶段抽样方法，选取了中国广东省深圳市龙岗区的10686名成年人参与本研究。在2020年和2021年进行了调查，以测量参与者的人口统计学数据和健康状况。进行二元逻辑回归、受限立方样条回归和亚组分析，以探讨BMI与抑郁症状之间的关系。
结果显示BMI与抑郁之间呈U形关系。肥胖和体重不足都会增加参与者患抑郁症的风险，尤其是在年轻、高学历、单身和就业的参与者亚组中。
这些发现表明，成年人应努力保持正常体重，以预防抑郁症并维护身心健康。
