Mexican-heritage youth living along the U.S.-Mexico border have higher rates of obesity than non-Hispanic Whites. Parenting strategies may influence youth physical activity (PA) and sedentary behaviors (SB) mitigating these obesity rates; however, parenting strategies have not been well examined in Hispanic cultures. Therefore, we examined relationships between parenting strategies and PA and SB of Mexican-heritage youth. Mother-child dyads (n = 121 dyads) were surveyed during the summer and school-year. Quantile regression estimated relationships between parenting strategies, and PA and SB. Summer. Reinforcement was negatively associated with moderate-to-vigorous PA (MVPA) among more active youth (β = −364.4); limit setting was negatively associated with SB among less sedentary youth (β = −23.3); and use of discipline was negatively associated with sedentary screen time in youth reporting less screen use (β = −3.2). School-year. Males reported more MVPA (773.9 min/week) than females (738.7 min/week). Reinforcement was positively associated with weekly MVPA among more active youth (β = 173.6), fewer sedentary minutes/week among all youth, and fewer sedentary screen time minutes among less sedentary youth (β = −6.4). Parenting strategies are related with PA and SB. Investigators should focus on identifying modifiable parenting strategies to address the various needs presented during summertime and school-year for Mexican-heritage youth.
