To examine the association of dietary diversity (assessed using the Household Dietary Diversity Score[HDDS]) and body mass index (BMI) over 6 months in a cohort of people living with HIV (PLWH) in Accra, Ghana.
A prospective cohort design was used, and 152 PLWH were recruited from 6 District Hospitals in Accra and followed for 6 months with data collected at baseline, 3 and 6 months. Repeated measures models were used to estimate the association between dietary diversity and BMI over time.
Study participants were mostly female (84%), with a mean age of 40, had been living with HIV for an average of 3.5years and earned less than $78/month (67%). Almost half (47%) of the participants were either overweight or obese (BMI≥25kgm2).
The mean dietary diversity score was 8 (out of 12) and when HDDS was categorized into low (0-8) and high (9-12), 42% of the participants had high dietary diversity scores. Cereal grains, vegetables, oils, salt and other condiments were food groups consumed by over 90% of study participants. Dietary diversity was not significantly associated with BMI after adjusting for income, sex, time of observation and food insecurity (p=0.30). The interaction between dietary diversity and time of observation was not significant and so was removed from the final model. Those in the higher income category had lower BMI over time when compared to those in the lower income category after adjusting for other covariates (p=0.03).
In this cohort of PLWH, dietary diversity was not associated with BMI over time. The high levels of overweight and obesity observed were concerning and could put those individuals at a higher risk of developing chronic non-communicable diseases. There is a need for nutrition education and other interventions to address the increasing trend of overweight/obesity among PLWH in this era of wide coverage of antiretroviral therapy medications.
