Association Between Dietary Consumption, Anthropometric Measures And Body Composition Of Rural And Urban Ghanaian Adults; A Cross Sectional Study.
Abstract Background Overweight and obesity have become threats to public health in all regions across the globe including sub-Saharan Africa where prevalence used to be low. Policies to regulate the food environment and promote healthy food consumption look promising to reducing the prevalence obesity but in Ghana there is not enough data to elicit a policy response. This study assessed the association between dietary consumption, Body Mass Index (BMI) and body composition among rural and urban Ghanaian adults.Methods This was a cross-sectional study involving 565 Ghanaian adults. Structured interviewer-administered questionnaires were used to collect information on socio-demographics. Dietary consumption was assessed using household food frequency questionnaire and 24-hour recall. Height, weight, BMI, waist circumference and body composition of all participants were determined. Mann Whitney U test was used to analyze differences in anthropometric measures, body composition and consumption among rural and urban participants. Principal component analysis was used to analyze household food frequency data. Chi-square was used to measure differences in obesity prevalence by community and gender. Multinomial logistic regression was used to model the risk factors associated with obesity.Results The prevalence of overweight and obesity using BMI were 29.9 and 22.9 respectively. Use of waist circumference measurement resulted in the highest overall obesity prevalence of 41.5%. Prevalence of obesity was higher among females compared to males across all measures with the exception of visceral fat that showed no significant difference. Four different patterns were derived from principal component analysis. Vegetable convenience dietary pattern showed significant negative correlation with visceral fat (r=-0.142, p 0.002), body fat (r=-0.102, p 0.209) and BMI (r=-0.136, p 0.003). Multinomial logistic regression revealed that males (OR 21.968, CI 10.876-44.373, p-value < 0.001) and rural participants (OR 1.684, CI 1.039-2.729, p-value <0.05) had higher odds of being of normal weight.Conclusion Prevalence of overweight and obesity continue to rise in Ghana, especially among females. Public education and screening as well as interventions that regulate the food environment and makes affordable and available healthy food options are needed to control the rise in obesity prevalence.
