Neighborhood and Parental Supports for Physical Activity in Minority Adolescents

Abstract

Background Few studies have examined environmental, home and parental supports for physical activity in underserved adolescents (low income, ethnic minority). Given the increasing incidence of obesity in minority adolescents, it is important to better understand ecologic determinants of physical activity in these youth. This study used an ecologic model to evaluate the significance of neighborhood, home, and parental supports for physical activity on moderate-to-vigorous (MV) physical activity in underserved adolescents. Design The study was a secondary data analysis of a randomized controlled school-based trial “Active by Choice Today” (ACT) for increasing physical activity in underserved 6th graders. Schools were matched on school size, percentage minorities, percentage free or reduced-price lunch, and urban or rural setting prior to randomization. This study used a randomly selected sample of parents (n=280) from the intervention and control schools whose adolescent was enrolled in larger trial. Setting/participants A total of 679 6th-grade students (mean age, 11.4 years, 70% African-American, 76% free or reduced-price lunch, 52% female) participated in the larger trial. Parents of 280 youth were contacted to participate in a telephone survey and 198 (71%) took part in the study. Interventions The ACT trial was designed to test the efficacy of a 17-week (1 academic year) motivational plus behavioral skills intervention versus comparison after-school programs on increasing physical activity. A telephone survey was developed and administered within 6 months after the trial began on parents of 198 adolescents from the ACT randomized school-based trial during 2005–2007. Main Outcome Measures The primary outcome measure was adolescent MVPA based on 7-day accelerometry estimates from baseline to mid-intervention. The data were analyzed in 2010–2011 and included both parent and adolescent self-reports of environmental, home and family supports for physical activity. Results Regression analyses indicated a significant effect of parental and neighborhood supports for physical activity on adolescent MVPA. Adolescents who perceived higher (vs lower) levels of parental support for physical activity engaged in more minutes of MVPA (B = 3.01, SE = 1.38, p < .05) at mid-intervention. Adolescents who lived in neighborhoods with more (vs fewer) supports for physical activity (parks, lighting), also engaged in more minutes MVPA (B = 4.27, SE = 2.15, p < .05). Conclusions Support from parents and neighborhood quality are both associated with increased physical activity in underserved adolescents.

Children’s Objective Physical Activity by Location: Why the Neighborhood Matters

“…For youth, trends of using 4+ METs as the cutoff for moderate activity is growing (3,26,27). Still, there remains no set consensus and 3+ METs criteria for youth remains a valid approach (14,17,31), and it is recommended by the Physical Activity Guidelines Working Group (19). In addition, our average daily MVPA estimates are similar to those obtained by Nader et al (17).…”

Mobile apps for pediatric obesity prevention and treatment, healthy eating, and physical activity promotion: just fun and games?

“…The apps tested present a huge lost opportunity for the provision of solid, evidence-based strategies and recommendations for health change, with a group of people demonstrating interest and initiative to make changes (by downloading the apps). Additionally, despite research showing that parents are a crucial part of pediatric obesity prevention and treatment (including the promotion of HE [29] and PA [30]), most apps did not target parents/families, instead focusing solely on the individual child. Future efforts for the prevention and treatment of pediatric obesity must look beyond the individual and attempt to change elements of the social and physical environments that can promote or inhibit behavior change.…”

Nutritional status of urban adolescents: individual, household and neighborhood factors based on data from The BH Health Study

“…The influence of family habits related to physical activity and diet is well documented in the literature 36,37,38 . However, the results showed no direct association between the consumption of soft drinks more than five days a week and thinness, and between being overweight and the habit of consuming fruit and vegetables among adults.…”
