Abstract

The prevalence of cardiometabolic diseases like obesity, hypertension, diabetes, and dyslipidaemia is increasing rapidly, particularly in low- and middle-income countries (LMICs). Informal workers in Ghana, who account for the majority of the national workforce, contribute significantly to the country's socioeconomic growth. Often, their work predisposes them to cardiometabolic diseases. This study examines the cardiometabolic burden, its associated factors, and the diagnostic heterogeneity among this unique population.
This study used cross-sectional data on 948 informal workers (traders, fisherfolk, artisans, farmers, and drivers) in the Cape Coast Metropolis, Ghana. Sociodemographic, lifestyle, anthropometric, and biochemical data were obtained in accordance with standard procedures. Multiple diagnostic criteria were used to characterise diabetes, prediabetes, and obesity. Diagnostic concordance was evaluated using Venn diagrams and UpSet plots, and independent associated factors were identified using multivariate logistic regression.
The prevalence of obesity, hypertension, prediabetes, and diabetes was 45.46%, 40.19%, 29.54%, and 13.40%, respectively. Women and middle-aged adults (45-59 years) were most impacted. There was significant heterogeneity in classification criteria, with just 9.28% of obese participants and 2.36% of diabetic participants being diagnosed by all diagnostic criteria. While the absence of childhood obesity was associated with lower odds of obesity (aOR = 0.43, 95% CI: 0.30-0.61), diabetes (aOR = 0.64, 95% CI: 0.42-0.99), and hypertension (aOR = 0.63, 95% CI: 0.46-0.88), older age (≥60 years) was strongly associated with obesity (aOR = 2.54, 95% CI: 1.51-4.32) and hypertension (aOR = 4.82, 95% CI: 3.06-7.68). Low physical activity was significantly linked to hypertension (aOR = 1.73, 95% CI: 1.16-2.62), and elevated triglycerides were associated with diabetes (aOR = 2.16, 95% CI: 1.21-3.75) and hypertension (aOR = 1.84, 95% CI: 1.13-3.04).
The burden of cardiometabolic diseases among Ghana's informal workers is disproportionately high and diagnostically diverse. The findings emphasise the critical need for sex- and occupation-sensitive health interventions, life-course prevention strategies, and context-specific diagnostic guidelines to reduce cardiometabolic disease risk among informal workers in LMICs.
