The study aims to explore the relationship between modifiable lifestyle factors (physical activity, sedentary time, body composition, muscle strength) and mental health, and predict future changes in mental health.
A cross-sectional survey was conducted on 133 men (age: 29.03 ± 6.605 years, BMI: 23.58 ± 2.688 kg/m²) to assess baseline body composition, muscle strength, sedentary time, and mental health, with follow-up at 3 months. F-tests were employed to compare the differences in mental health on sedentary time and body composition variables. Spearman correlation analysis was used to examine correlations between variables.
Spearman's correlation analysis showed that sedentary time, muscle strength and mental health of the subjects were significantly correlated. BMI, BFM, BFMI, PBF were higher in subjects with ≥ 4 h of sedentary time than in the other two shorter sedentary time groups. Subjects with higher PBF (p = 0.047, η = 0.030) and BFM (p = 0.032, η = 0.035) had severer depression. Subjects who sat for ≥ 4 h at a time were more severely depressed than those who sat for 2-4 h (p = 0.020). Change in depression was significantly negatively correlated with BMI, BFM, BFMI and PBF. Subjects with higher PBF (p = 0.023, η = 0.050) and BFM (p = 0.005, η = 0.075) at the baseline had less change in depression.
A Significant correlation was found between sedentary time, body composition and mental health, and baseline body composition predicted changes in mood three months later.
本研究旨在探讨可改变的生活方式因素（身体活动、久坐时间、身体成分、肌肉力量）与心理健康之间的关系，并预测心理健康的未来变化。
对133名男性（年龄：29.03±6.605岁，BMI：23.58±2.688kg/m²）进行横断面调查，以评估基线身体成分、肌肉力量、久坐时间和心理健康状况，并在3个月时进行随访。采用F检验比较久坐时间和身体成分变量对心理健康的差异。使用Spearman相关性分析来检验变量之间的相关性。
Spearman相关性分析表明，受试者的久坐时间、肌肉力量与心理健康显著相关。久坐时间≥4小时的受试者的BMI、BFM、BFMI、PBF高于其他两个较短久坐时间组。PBF较高（p=0.047，η=0.030）和BFM较高（p=0.032，η=0.035）的受试者抑郁更严重。一次久坐≥4小时的受试者比久坐2-4小时的受试者抑郁更严重（p=0.020）。抑郁变化与BMI、BFM、BFMI和PBF显著负相关。基线时PBF较高（p=0.023，η=0.050）和BFM较高（p=0.005，η=0.075）的受试者抑郁变化较小。
久坐时间、身体成分与心理健康之间存在显著相关性，基线身体成分可预测三个月后的情绪变化。
