The roles of physical activity and sedentary behavior on Hispanic children's mental health: a motor skill perspective.

PURPOSE

Motor competence (MC) has been recognized as the foundation for life-time moderate-to-vigorous physical activity (MVPA) as well as an influential factor in reducing sedentary behavior during childhood. Guided by Blair et al.'s health model, the purpose of this study was to examine the behavioral mechanism of mental health including physical, psychosocial, and cognitive health among Hispanic children related to MC and MVPA.

METHODS

A prospective research design was used with two-wave assessments across one academic year. A total of 141 Hispanic kindergarteners (Mean = 5.37, SD = 0.48) were recruited in Texas. Nearly all (94.3%) of the participants were from low-income families based on the Income Eligibility Guidelines. The study was approved by the University Research Review Board, and informed consent was obtained from parents/guardians prior to starting the study.

RESULTS

Multiple regressions indicated that manipulative skill was a significant predictor of physical and psychosocial health (β = 0.21, β = 0.26, p < 0.05, respectively) and locomotor skill served as a significant predictor for cognitive health (β = 0.22, p < 0.01), after controlling for BMI. Bootstrapping analyses supported the statistical significance of indirect effects of MC on mental health outcomes through MVPA (95% CI [0.031, 0.119]) and sedentary behavior (95% CI [0.054, 0.235]), respectively.

CONCLUSION

The results suggest that skill-based activities/games, with instructions, should be encouraged during school-based physical activity and health promotion programs in childhood education. Better understanding of the early effects of MC may contribute to designing strategies to promote Hispanic children's well-being.
