Built environmental characteristics, physical activity, diet, and nutritional status in Accra, Ghana: a cross-sectional study.
Article in BMC public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe high prevalence of noncommunicable diseases related to lifestyle, diet, and obesity is a global health concern, including in lower-middle income countries. There is increasing evidence that characteristics of the built environment can influence residents’ lifestyle, including physical activity and diet. The aim of this study is to describe the characteristics of the built environment and the lifestyle and nutritional status of residents living in different neighborhoods of Accra, Ghana.
methodsA cross-sectional study was conducted in Accra between June and July 2023. Twelve neighborhoods were randomly selected on the basis of high and low values of residential density and socioeconomic status. Sociodemographic, household and neighborhood information was collected using the Neighborhood Environment Walkability Scale (NEWS-A) questionnaire adapted for Africa. Physical activity was assessed by the WHO Global Physical Activity Questionnaire. Differences between variables by neighborhood types were analyzed using Chi square test and Kruskal Wallis test, and pairwise comparisons were performed by Dunn-Bonferroni test.
resultsA total of 631 adults (median age 34.0 years, female 60.5%) participated in the survey. The built environmental characteristics of the different neighborhood types showed significant differences in all subscales of the NEWS (land use mix, street connectivity, safety for walking and cycling, aesthetics, safety from traffic, safety from crime, personal safety, and stranger danger). Work, transport-related and leisure-time physical activity levels and diet (consumption of fruits and vegetables, sweets, sugar-sweetened beverages, fast food and street food, alcohol) revealed variations between neighborhoods. Differences in nutritional status were inconsistent across neighborhood types.
conclusionsThis study was the first to examine the associations between environmental characteristics, physical activity, diet and BMI in an urban setting in Ghana. Initial descriptive results revealed significant differences in health behaviors and the characteristics of the built environment between neighborhoods in Accra. The associations between these factors require further analysis.
