Randomized Informational Intervention and Adult Park Use and Park-Based Physical Activity in Low-Income, Racially Diverse Urban Neighborhoods.

BACKGROUND: Neighborhood parks are important locations to encourage and stimulate physical activity (PA) among the urban population. This study aims to evaluate the impact of an informational intervention on adult park use and PA behaviors in 3 low-income, racially diverse urban neighborhoods in Minneapolis, MN. METHOD: The study employed a household-level randomized controlled trial and collected baseline and follow-up data from 171 participants. Within each neighborhood, participants were randomized to an informational intervention or to a no-intervention comparison. Intervention households received monthly, neighborhood-specific newsletters about park-based PA opportunities, park program brochures, trail maps, and activity guides. RESULTS: The average treatment effect of the newsletter intervention was positive yet moderated by respondent age. For a 20-year-old resident, treatment was associated with 0.97 (P < .05) additional park visits and 31.24 (P < .05) additional minutes of park-based PA over a 3-day recall period. For 40-year-old respondents, these positive effects are smaller at 0.36 (P < .05) additional visits and 4.66 (P < .05) additional minutes, respectively. CONCLUSIONS: An intervention to increase awareness about park-based PA opportunities and benefits increased self-reported park visits and in-park PA among adults who lived in low-income, racially diverse neighborhoods.

Understanding subjective well-being: perspectives from psychology and public health.

BACKGROUND: Individual subjective well-being (SWB) is essential for creating and maintaining healthy, productive societies. The literature on SWB is vast and dispersed across multiple disciplines. However, few reviews have summarized the theoretical and empirical tenets of SWB literature across disciplinary boundaries. METHODS: We cataloged and consolidated SWB-related theories and empirical evidence from the fields of psychology and public health using a combination of online catalogs of scholarly articles and online search engines to retrieve relevant articles. For both theories and determinants/correlates of SWB, PubMed, PsychINFO, and Google Scholar were used to obtain relevant articles. Articles for the review were screened for relevance, varied perspectives, journal impact, geographic location of study, and topicality. A core theme of SWB empirical literature was the identification of SWB determinants/correlates, and over 100 research articles were reviewed and summarized for this review. RESULTS: We found that SWB theories can be classified into four groups: fulfillment and engagement theories, personal orientation theories, evaluative theories, and emotional theories. A critical analysis of the conflicts and overlaps between these theories reveals the lack of a coherent theoretical and methodological framework that would make empirical research systematically comparable. We found that determinants/correlates of SWB can be grouped into seven broad categories: basic demographics, socioeconomic status, health and functioning, personality, social support, religion and culture, and geography and infrastructure. However, these are rarely studied consistently or used to test theories. CONCLUSIONS: The lack of a clear, unifying theoretical basis for categorizing and comparing empirical studies can potentially be overcome using an operationalizable criterion that focuses on the dimension of SWB studied, measure of SWB used, design of the study, study population, and types of determinants and correlates. From our review of the empirical literature on SWB, we found that the seven categories of determinants/correlates identified may potentially be used to improve the link between theory and empirical research, and that the overlap in the determinant/correlates as they relate to multiple theory categories may enable us to test theories in unison. However, doing so in the future would require a conscious effort by researchers in several areas, which are discussed.

Park-Use Behavior and Perceptions by Race, Hispanic Origin, and Immigrant Status in Minneapolis, MN: Implications on Park Strategies for Addressing Health Disparities.

The study examines the connections between minority status, park use behavior, and park-related perceptions using recent survey data from three low-income neighborhoods in Minneapolis, MN. Blacks and foreign-born residents are found to underutilize parks. Blacks, Asians, and American Indians perceive fewer health benefits of parks than whites, including the benefits of parks for providing exercise/relaxation opportunities and family gathering spaces. Foreign-born residents, blacks, and Hispanics perceive greater and unique barriers to park use in terms of not feeling welcome, cultural and language restrictions, program schedule and pricing concerns, and/or facility maintenance and mismatch concerns. When designing park strategies for addressing health disparities, we recommend to focus the efforts on increasing awareness of park-related health benefits and removing specific park use barriers among minority and foreign-born communities.

Family structure and park use among parents.

BACKGROUND: Despite the increasingly diversified family structure in the U.S., little research examines differences in park use between nontraditional and traditional family structures. PURPOSE: This study examines family-structure differences in parent park use. It was hypothesized that working single parents and dual-worker parents have lower levels of park use than parents in two-parent, single-worker families. METHODS: Data from a 2010 park-use survey in three urban neighborhoods in Minneapolis MN (N=261 parents) were analyzed in 2012. Multiple variables of park use were developed, including recalled measures over the past 3 days and over the past year. Family-structure differences in these variables were examined using multivariate regression analyses. RESULTS: After controlling for spatial clustering effects and confounding factors, working single parents reported 32.6% (p<0.10) fewer park visits and 62.0% (p<0.05) less time spent in parks in the past 3 days than parents in two-parent, single-worker families. Dual-worker parents did not report fewer park visits in the past 3 days than parents in two-parent, single-worker families, yet the length of time they spent in parks during these visits was 41.5% (p<0.10) less. Family-structure differences in past-year park-use measures were not significant. CONCLUSIONS: This research shows the importance of including family-structure variables and both recent and longer-term recalled measures of park use in park-use studies. Greater attention to the recreation needs of working single parents and dual-worker parents is needed in descriptive and intervention research aiming to promote park use among families with children.

Neighborhood green, social support, physical activity, and stress: assessing the cumulative impact.

We estimate the cumulative stress mitigating impact of neighborhood greenness by investigating whether neighborhood green mitigates stress directly, and indirectly by encouraging physical activity and/or fostering social support. Using data from a recent community health survey in Chicago and two-stage instrumental variables regression modeling, we find that different components of neighborhood green play distinct roles in influencing stress. Park spaces are found to indirectly mitigate stress by fostering social support. Overall neighborhood vegetation is found to have direct stress mitigation impact, yet the impact is counteracted by its negative effect on social support. When comparing the effect size, park spaces show a more positive impact on health and well-being than the overall neighborhood vegetation level. Policy makers are recommended to focus on creating structured green spaces with public recreation and socialization opportunities rather than simply conserving green spaces in the neighborhood. Previous studies, as they often investigate the direct impact only and rarely use multiple measures of greenness, may have mis-estimated health benefits of neighborhood green.
