Built environmental characteristics, physical activity in neighbourhoods of Accra, Ghana

Abstract There is increasing evidence that characteristics of the built environment can influence residents’ lifestyles, physical activity thereby influencing the development of obesity and non-communicable diseases even in low- and middle-income countries. The aim of this study is to describe the characteristics of the built and the social environment of neighbourhoods of Accra, Ghana, and to explore association between neighbourhood characteristics and the physical activity of the residents. A cross-sectional study was conducted in Accra, 12 neighbourhoods were randomly selected based on high and low values of residential density and socioeconomic status. Sociodemographic, household and neighbourhood information were collected with an adapted questionnaire of NEWS (Neighbourhood Environment Walkability Scale) for Africa. Physical activity was assessed by WHO Global Physical Activity Questionnaire and social cohesion by the Perceived Neighbourhood Social Cohesion Questionnaire. Differences between variables by neighbourhood types were analysed using Chi square test and Kruskal Wallis test. Generalized linear model was performed to determine the association between neighbourhood characteristics and residents’ physical activity. The built environmental characteristics of different neighbourhood types and the physical activity of the residents showed significant differences. The associations indicated that individuals living in high residential density neighbourhoods had increased levels of engaging in physical activities. Land use mix, street connectivity, safety, aesthetics and social cohesion of neighbourhoods showed correlation with physical activity of residents. The built environment and social characteristics of neighbourhoods can influence the lifestyle and physical activity of residents in Accra, Ghana. Key messages • High residential density neighbourhoods correlated with higher level of physical activity. • Land use, street connectivity, safety and aesthetic of neighbourhoods and social cohesion showed correlation with physical activity.
