001). We

proposed a final model (Fig. 2) to predict PA based on the nested regression model analysis and mediation analysis. On the basis of this model, only the predisposing factors, able and worth, predicted MPAR directly. All reinforcing and enabling factors, except the hypothesized language barriers, predicted MPAR indirectly through able and worth. Sex and BMI were also predictors of MPAR. Over half of the participants in this study met the PA recommendation, indicating that they were more physically active than many of their contemporaries in China,33 as well as more active than what had previously been reported among those enrolled in American colleges find more and universities.3 This may be because the physical and social environment of American society has positively influenced their participation.34 For example, in the current study, social and physical BGB324 datasheet environment factors, such as social support, role modeling, and accessibility to PA resources, were found to have indirect effects on PA participation among Chinese

international students. This finding may result from efforts underway in America focused on reprioritizing healthy, active living and building environments that support such practices (e.g., Active Community Environments, Rails to Trails, Michelle Obama’s efforts as First Lady of the United States focused on childhood obesity). It would seem that such endeavors are positively influencing Chinese international students, although the

present study does not allow for causal inference. Although the acculturation effect on PA participation remains unclear,35 the current study does suggest a potential Parvulin protective effect of American culture on Chinese international students’ PA behavior. Also, males in this sample were 1.49 times more likely than were the females to meet the PA recommendation. This is consistent with previous research suggesting that female college students are less active than are their male peers.13 BMI also significantly predicted MPAR. Contrary to previous findings, the current study showed that having a higher BMI was associated with greater odds of meeting the PA recommendation. Given that the majority of participants had a normal body weight, a higher BMI may indicate more muscle mass and a more physically active lifestyle. Or, it could be that the students with higher BMI values were using PA as a means of counteracting the situation. Consistent with Welk’s YPAP model,5 the factors that predicted MPAR were the predisposing, enabling, and reinforcing factors. However, the predisposing factors (i.e., perceived competence, self-efficacy, attitude, and enjoyment) were the only factors to predict MPAR directly. Others have also observed the importance of these predictors on PA participation among different college-aged population segments.
