Examining the Correlates of Physical Activity for Whites, Blacks and Hispanics in a National Sample: The Role of Demographics, Social Connections and Self-Efficacy
Unformatted Document Text:  12 Estimates of Indirect Effects for Whites, Blacks and Hispanics In exploring the effects of demographics on physical activity and the effects of self-efficacy across races, it is important to examine the indirect or “mediating” effects of variables on one another.

As Table 6 shows, social connections and self-efficacy mediate the influence of demographics for Whites, resulting in two indirect paths.

Estimates of Indirect Effects for Whites, Blacks and Hispanics
In exploring the effects of demographics on physical activity and the effects of
self-efficacy across races, it is important to examine the indirect or “mediating” effects of
variables on one another. For example, do higher income individuals feel more in charge of
their lives?, and do such feelings affect how regular one exercise? As Table 6 shows, social
connections and self-efficacy mediate the influence of demographics for Whites, resulting in
two indirect paths. The first path was gender to physical activity via social connections ( =
0.0494) and the second path to physical activity was mediated through self-efficacy (
=
0.0024). This means that demographics make a difference in individual's participation in
physical activity through social and cognitive factors. Female Caucasians who have better
social connections and with higher self-efficacy engage in more physical activity. As such,
how self-efficacious individuals feel and how well they socially connected with other people
influence how often they exercise.
Among Blacks, self-efficacy mediated the influence of both gender and income on
social connection, which in turn affected physical activity ( = 0.019074). Male as well as
those having higher income are more self-efficacious, better connected and exercise more
regularly. Social connections ( = 0.1254) and self-efficacy ( = 0.021318) both mediated the
influence of age on physical activity. With regard to Hispanics, gender affected physical
activity via social connections ( = 0.066). Females who have better social connections
