ABSTRACT

Background: An understanding of the contributing factors to be considered when examining how individuals engage in physical activity is important for promoting population-based physical activity. The environment influences long-term effects on population-based health behaviors. Personal variables, such as self-efficacy and social support, can act as mediators of the predictive relationship between the environment and physical activity. The present study examines the direct and indirect effects of environmental, psychological, and social factors on walking, moderate-intensity activity excluding walking, and vigorous-intensity activity among Japanese adults.

Methods: The participants included 1,928 Japanese adults aged 20-79 years. Seven sociodemographic attributes (e.g., gender, age, education level, employment status), psychological variables (self-efficacy, pros, and cons), social variables (social support), environmental variables (home fitness equipment, access to facilities, neighborhood safety, aesthetic sensibilities, and frequency of observing others exercising), and the International Physical Activity Questionnaire were assessed via an Internet-based survey. Structural equation modeling was conducted to determine associations between environmental, psychological, and social factors with physical activity.

Results: Environmental factors could be seen to have indirect effects on physical activity through their influence on psychological and social variables such as self-efficacy, pros and cons, and social support. The strongest indirect effects could be observed by examining the consequences of environmental factors on physical activity through cons to self-efficacy. The total effects of environmental factors on physical activity were 0.02 on walking, 0.02 on moderate-intensity activity excluding walking, and 0.05 on vigorous-intensity activity.

Conclusions: The present study indicates that environmental factors had indirect effects on walking, moderate-intensity activity excluding walking and vigorous-intensity activity among Japanese adults, especially through the effects on these factors of self-efficacy, social support, and pros and cons. The findings of the present study imply that intervention strategies to promote more engagement in physical activity for population-based health promotion may be necessary.

Figure 2: Environmental, social, and psychological affects on moderateintensity activity excluding walking. GFI = .921, AGFI = .908, RMSEA = .047. Only statistically significant paths are indicated in this figure. All paths are statistically significant at p < .05.

Mentions: The moderate-intensity activity excluding walking model was similar to the walking model (figure 2). The present study identified no significant associations between environmental factors and self-efficacy, between cons and social support, and no association of environmental factors, pros, cons, and social support with moderate-intensity physical activity excluding walking (GFI = .921, AGFI = .908, RMSEA = .047). Recalculation of the model using modified indices reduced the AIC value from 2681.579 to 2679.833. Thus, the final model demonstrated an acceptable fit (GFI = .921, AGFI = .908, RMSEA = .047). Environmental factors did not directly affect moderate-intensity activity excluding walking; however self-efficacy directly affected moderate-intensity activity excluding walking (.087). The path coefficient for indirect effects of environmental factor on moderate-intensity activity excluding walking through pros and self-efficacy was .004; through pros, social support, and self-efficacy was .002; through cons and self-efficacy was .009; and through social support and self-efficacy was .003. The total effect of environmental factors on moderate-intensity activity excluding walking was .020.
