Correlates of Physical Activity Differ by Sex and Country of Birth Among Mexican-Heritage Youth

Barriers to physical activity (PA) may be experienced differently by sex and country of birth. We examine psychosocial correlates of PA in four groups based on sex (boy/girl) and country of birth [Mexico/United States (U.S.)]. 1154 Mexican heritage adolescents residing in Houston, Texas provided psychosocial data in 2008–09 and PA (number of days per week active for at least 60 min) in 2010–11 (N = 1001). Poisson regression models were fitted for each groups. Among boys, English language preference (p US-born = 0.045, p Mexico-born = 0.008) and higher subjective social status (p US-born = 0.002, p Mexico-born = 0.031) were associated with increased PA. Body image dissatisfaction was associated with decreased PA in Mexico-born girls (p = 0.007). Sensation-seeking tendencies were associated with increased PA among all groups; anxiety was associated with decreased PA among all but U.S.-born boys. Tailoring PA interventions to key sex-specific psychosocial correlates rather than country of birth may enhance efficacy of interventions to increase PA levels among Mexican heritage adolescents.
