O sucesso de estratégias intervencionistas voltadas à promoção da atividade física perpassa pelo entendimento dos fatores determinantes deste comportamento. Sendo assim, o objetivo do presente estudo foi verificar as possíveis associações entre o suporte social e a prática de atividade física no lazer em adultos. Trata-se de um estudo transversal conduzido em 227 adultos (152 homens) com idade entre 18 e 65 anos, selecionados de uma empresa localizada na cidade de Londrina/PR. Informações sobre a atividade física no lazer foram obtidas por meio do Questionário Internacional de Atividade Física (versão longa). Foram considerados ativos os sujeitos que relataram uma quantia mínima de 150 minutos semanais em caminhadas (CAM) ou em atividades físicas de intensidades moderadas a vigorosas (AFMV). O suporte social foi determinado por meio da Escala de Suporte Social para Atividades Físicas. Análises de regressão de Poisson brutas e ajustadas (sexo, idade, estado civil e escolaridade) foram utilizados para testar as associações entre o suporte social recebido de familiares ou amigos e CAM e AFMV. A maioria dos sujeitos relataram nunca ter recebido suporte social de familiares e amigos para a prática de CAM e AFMV. Análises brutas e ajustadas revelaram que o suporte social foi significante e positivamente associado à AFMV (P < 0,01). A probabilidade de ser ativo no lazer foi 75% maior nos indivíduos que receberam suporte social de amigos (RP = 1,75; IC95% = 1,09 – 2,81) e 124% maior entre aqueles que receberam suporte social de forma combinada (família e amigos) (RP = 2,24; IC95% = 1,55 – 3,25). O suporte social não foi associado à prática de CAM (P = 0,75). Em conclusão, o suporte social parece se constituir como um correlato da prática de AFMV. O apoio de amigos e familiares pode se constituir como uma importante ferramenta para a promoção da atividade física em adultos.AbstractThe success of interventional strategies aimed at promoting physical activity passes by the understanding of the determinant factors of this behavior. Thus, the aim of this study was to investigate possible associations between social support and the practice of leisure-time physical activity among adults. This is a cross-sectional study conducted with 227 adults (152 men) aged between 18 and 65 years, selected from a company located in the city of Londrina/PR. Information on leisure-time physical activity were obtained using the International Physical Activity Questionnaire (long version). Subjects who reported a minimum amount of 150 minutes per week on walks (WAL) or moderate to vigorous physical activities (MVPA) were considered active. Social support was determined using the Social Support Scale for Physical Activities. Crude and adjusted Poisson regression analyses (gender, age, marital status and educational level) were used to test associations between social support received from family or friends and WAL and MVPA. Most subjects reported never having received social support from family and friends to practice WAL and MVPA. Crude and adjusted analyses revealed that social support was significantly and positively associated with MVPA (P < 0.01). The probability of being active in leisure-time was 75% higher in subjects who received social support from friends (PR = 1.75, CI 95% = 1.09 - 2.81) and 124 % higher among those who received social support in combination (family and friends) (PR = 2.24, CI 95% = 1.55 - 3.25). Social support was not associated with the practice of WAL (P = 0.75). In conclusion, social support seems to be correlated with the practice of MVPA. The support from family and friends can be an important tool for promoting physical activity in adults.
