Abstract

Background: Regular street food consumers (RSFCs) in Africa are at an increased risk of unhealthy eating practices, which have been associated with intermediate risk factors of cardio-metabolic diseases. However, knowledge of the magnitude and correlates of these risk factors is limited in Tanzania. This study aimed to fill this gap using data collected from regular street food consumers in Dar es Salaam, the largest city in Tanzania.
Methodology: A cross-sectional study was carried out among 560 RSFCs in three districts of Dar es Salaam between July-September 2018. Information on socio-economic factors and demographics, behavioral risks, anthropometric and biochemical indicators was collected. Adjusted odds ratios (OR) and prevalence ratio (PR) with corresponding 95% confidence intervals (CI) were estimated using multivariable binary logistic and modified Poisson regression models, respectively.
Results: On average, participants consumed 11 street food meals/week. The prevalence (95% CI) of cardio-metabolic risk factors was 63.9% (60.6-69.9%) for overweight/obesity, 42.5% (38.3-46.9%) for raised blood pressure, 13.5% (10.9-16.8%) for raised triglycerides and 6.6% (4.9-9.3%) for raised glucose levels. The correlates of overweight/obesity were female vs. male sex (APR=1.3; 95%CI 1.2-1.5), age of 41-64 vs. 25-40 years (APR=1.4; 95%CI 1.2-1.6), high vs. low income (APR=1.2; 95%CI 1.04-1.3), being married/cohabiting vs. other (APR=1.2; 95%CI 1.01-1.4) and family history of diabetes vs. no family history (APR=1.2; 95%CI 1.01-1.3). Age 41-64 vs. 25-40 years, was the only significant factor associated with raised blood pressure APR (95% CI) 2.2 (1.7-2.9) and raised glucose AOR (95% CI) 3.9 (1.5-10.5).
Conclusions: Our study revealed that RSFCs are at risk of cardio-metabolic health problems, especially women, middle-aged people and those with higher incomes. Transdisciplinary studies to understand the drivers of street food consumption are needed in order to inform interventions to mitigate the risk of developing cardio-metabolic diseases. These interventions should target both street food vendors and their consumers.
