Parks can be an important, low-cost neighborhood resource to increase physical activity and reduce overweight and obesity. The quality of parks, however, may impact use. This study used observational data to examine the relationships between park quality, park usage and levels of physical activity among users in 31 parks within low-income, African American neighborhoods. Relationships between park use and park characteristics (signs of disorder, attractiveness, and number of activity settings) varied by gender and user activity level. No variables of interest were significant for overall number of male users; whereas, disorder and attractiveness were significant for overall number of female users. Parks with signs of disorder were associated with 49% fewer female users (IRR = 0.51, 95% CI = (0.34–0.77)) and attractive parks with 146% more female users (IRR = 2.46, 95% CI = (1.39–4.33)). Similar significant relationships were found among active but not sedentary female users. Communities may consider increasing park maintenance and addressing attractiveness in existing parks as a relatively low-cost environmental strategy to encourage park use, increase physical activity, and reduce the burden of obesity, especially among women in low-income, African-American communities.

There has been a surge in diet-related mobile health (mHealth) interventions. However, diet-related mHealth research targeted toward racial/ethnic populations has been relatively limited. Focus groups with African American men and women from New Orleans, Louisiana, were conducted to (1) describe perceptions about healthy eating, (2) determine the acceptability of mHealth interventions, and (3) identify preferred mHealth intervention features. Descriptive statistics and thematic content analyses were performed. Qualitative data were organized within the context of the Theory of Planned Behavior and Social Cognitive Theory's theoretical components. Results may inform the development of mHealth research to improve eating behaviors among the target population.
