Obesity in Childhood and Adolescence: The Role of Motivation for Physical Activity, Self-Esteem, Implicit and Explicit Attitudes toward Obesity and Physical Activity.

The purpose of the present study was to compare attitudes toward body weight and physical activity in both regular-weight and overweight/obese children and adolescents, and assessing relations between attitudes and self-esteem, motivation for physical activity, life satisfaction and level of physical activity. A total of 126 children (Mage = 12.2, SD = 3.4), divided into two subsamples (i.e., overweight/obese, N = 44, and regular-weight), voluntarily participated in the study. A series of univariate analyses of variance was conducted to examine the differences in the study variables across the subsamples. Correlational analyses were conducted to examine the relationships among the variables. The results indicated that obese/overweight participants expressed a more positive implicit attitude toward the thin category than regular-weight participants. Furthermore, among overweight/obese participants, implicit attitude toward physical activity was significantly negatively correlated with explicit attitude toward physical activity and general self-esteem. Significant differences between obese/overweight and regular-weight participants indicated that the status in terms of weight played a key role in attitudes toward the explored constructs.

Exploring the relationship between sense of community and vigor in workplace community: The role of needs satisfaction and physical activity.

The present study aimed to increase understanding of well-being in workplace community by examining a moderated mediated model including the test of the mediating effect of needs satisfaction, and the moderating effect of physical activity on the sense of community-vigor relationship, in a longitudinal perspective. The sample was composed of 95 workers (63.6% females) who completed an online survey three times during a 4-month period. Results showed that the indirect effect of sense of community on vigor 4 months later, through satisfaction of need for relatedness, is significant among employees who practice a high level of moderate to vigorous physical activity. The findings suggest that (a) sense of community-conceived as a job resource-is responsible for needs satisfaction and may be considered an important component of the vigor process, and (b) that positive effects of physical activity can enhance employees' resource gains and recovery, favoring the experience of vigor in workplace community.
