Table 2 evaluated the relationship between various factors and PSC. It showed that factors such as sex, age, educational level, household income, number of chronic diseases, mental health were found to be related to PSC. Overall, male, age between 30–49 and 50–65, without chronic diseases, higher educated and higher-income demonstrated were more likely to PSC. In terms of mental health, depression, anxious, thoughts of suicide, and poor self-perceived health status all showed significant differences in relation to PSC. Furthermore, it was found that 22.9% of individuals who engage in PSC did not engage in regular exercise, which is highly relevant for further research.
Figure 1 shows the NP group and PP groups indicated significantly higher stress levels than the RP and RE groups. The NP group had significantly higher levels of depression than groups RP and RE, while there was no significant difference between the PP group and the other groups. In With regard to anxiety, the NP had significantly higher levels than the RE group, the RE group had significantly higher levels than the RP, and there was no significant difference between the P group and the other three groups. Individuals in the NP group had a significantly higher frequency of suicidal thoughts compared to individuals in the PP and RP groups, and the RE group also showed a significantly higher frequency of suicidal thoughts compared to the RP group. Regarding the statistical data on poor self-perceived health, the NP group showed a significantly higher frequency compared to the RE group, and the RE group had a significantly higher frequency compared to the PP and RP groups. However, there was no significant differences between the PP and RP groups.

Table 3 shows the relationship between mental health and PSC. The binary logistic regression analysis of Model 1 showed that compared to those who engage in PSC, those who do not were more likely to experience depression (1.47, 95% CI: 1.19–1.82), anxiety (1.86, 95% CI: 1.40–2.46), suicidal thoughts (2.21, 95% CI: 1.71–2.87), and poor self-perceived health status (2.82, 95% CI: 2.34–3.38), but there was no significant difference in terms of stress. Model 2, after adjusting for sex, age, education level, and household income, showed that PSC was related to stress (1.27, 95% CI: 1.12–1.43), anxiety (1.42, 95% CI: 1.06–1.91), suicidal thoughts (1.68, 95% CI: 1.28–2.19), and poor self-perceived health status (1.47, 95% CI: 1.21–1.79). Model 3, after adjusting for chronic diseases, still showed that PSC was related to stress (1.28, 95% CI: 1.13–1.45), anxiety (1.42, 95% CI: 1.06–1.90), suicidal thoughts (1.68, 95% CI: 1.28–2.20), and poor self-perceived health status (1.49, 95% CI: 1.22–1.81), indicating that the relationship between PSC and mental health is not affected by the presence or absence of chronic diseases.
Figure. 2–5 shows the results of the subgroup analysis of the regression model, which demonstrates the impact of participating in PSC on stress (Fig. 2), anxiety (Fig. 3), suicidal thoughts (Fig. 4), and poor self-perceived health (Fig. 5) among different subgroups defined by gender, age, and regular exercise habits. The significance of the interaction terms in the regression model was used to determine whether there were significant differences between three subgroups.
The impact of PSC on feeling stressed was significantly higher for women (1.52, 95% CI: 1.28–1.81), older adults (1.70, 95% CI: 1.14–2.53), and regular exercisers (1.18, 95% CI: 1.01–1.38) compared to other subgroups. (Fig. 2)
The impact of PSC on anxiety was significantly higher for older adults (2.81, 95% CI: 1.13–6.96) compared to other subgroups, with no significant differences by sex (p = 0.825) and regular exercise (p = 0.174). (Fig. 3)
The impact of PSC on suicidal thoughts showed no significant differences by sex (p = 0.394), age (p = 0.963), and regular exercise (p = 0.259). (Fig. 4)
The impact of PSC on poor self-perceived health status was significantly higher for older adults (2.26, 95% CI: 1.48–3.44) compared to other subgroups, with no significant differences by sex (p = 0.617) and regular exercise (p = 0.565). (Fig. 5)
