RESUMEN
BACKGROUND: Previous community-wide physical activity trials have been criticized for methodological limitations, lack of population-level changes, and insufficient reach among underserved communities. Social marketing is an effective technique for community-wide behavior change and can coincide with principles of community-based participatory research (CBPR). PURPOSE: A systematic scoping review of community-wide interventions (system-level) targeting physical activity and/or weight loss was conducted to (i) describe and critically discuss how social marketing strategies are implemented; (ii) identify which populations have been targeted, including underserved communities; (iii) evaluate the use of CBPR frameworks; (iv) assess retention rates; and (v) identify gaps in the literature and formulate future recommendations. METHODS: Eligible studies included those that: aimed to improve physical activity and/or weight loss on a community-wide level, used social marketing strategies, and were published between 2007 and 2022. RESULTS: Approximately 56% of the studies reported a positive impact on physical activity. All studies described social marketing details in alignment with the five principles of social marketing (product, promotion, place, price, and people). Only two studies explicitly identified CBPR as a guiding framework, but most studies used one (k = 8, 32%) or two (k = 12, 48%) community engagement strategies. Few studies included at least 50% representation of African American (k = 2) or Hispanic (k = 3) participants. CONCLUSIONS: This review highlights key gaps in the literature (e.g., lack of fully-developed CBPR frameworks, reach among underserved communities, randomized designs, use of theory), highlights examples of successful interventions, and opportunities for refining community-wide interventions using social marketing strategies.
The purpose of this study was to conduct a systematic scoping review of community-wide interventions targeting physical activity and/or weight loss to describe how social marketing strategies have been implemented, identify which populations have been targeted, evaluate the use of Community-Based Participatory Research (CBPR) frameworks, assess retention rates and identify gaps in the literature and formulate future recommendations. Over half of the studies reported a positive impact on physical activity. All studies described social marketing details in alignment with the five principles of social marketing (product, promotion, place, price, and people). Only two studies explicitly identified CBPR as a guiding framework, but most studies used one or two community engagement strategies. Few studies included at least 50% representation of African American or Hispanic participants. Many of the programs provided health information on the benefits of being active (e.g., educational lessons), behavioral strategies (e.g., walking with friends and family), or opportunities to increase walking and physical activity (e.g., community activities, walking clubs, maps for walking or biking, gardening). A number of the programs also addressed environmental facilitators for walking such as utilizing signage for stair use, accessing parks, or participating in community walking groups. Overall this review highlights key gaps in the literature (e.g., lack of fully-developed CBPR frameworks, reach among underserved communities, randomized designs, use of theory), and highlights examples of successful interventions, and opportunities for refining community-wide interventions using social marketing strategies.
