Background Despite the numerous studies on hypertension, the current literature reveals little about the relationship between patient comorbidities and uncontrolled hypertension in sub-Saharan Africa (SSA). We aimed to assess the associations between body size, dyslipidemia, diabetes and uncontrolled hypertension. Methods We harmonised and pooled individual-level data from 25 cross-sectional studies. We did a meta-analysis of individual participant data to assess the association between uncontrolled hypertension with body size, diabetes and dyslipidemia using a logistic regression while adjusting for potential confounders. Results The pooled dataset included 107,339 participants, of whom 64,811 were women and 42,528 were men. The pooled prevalence of uncontrolled hypertension (UHTN) among those on treatment was (3,449) 59.89%. The UHTN estimate ranged from 47.0% in Malawi to 80.0% in Guinea. Significant association were noted between UHTN and diabetes for all countries. The overall pooled estimate for UHTN among patients with diabetes was OR = 1.49 (95% CI 1.30 to 1.67). All countries had significant associations between UHTN and central obesity except for Gambia, Kenya and Tanzania. Study participants from Uganda with central obesity had the highest likelihood of UHTN OR = 1.14 (95% CI 0.38 to 1.89). All countries had significant associations between UHTN and general obesity except for Kenya, Tanzania and Uganda. Conclusions The prevalence of uncontrolled hypertension among patients with comorbidities is high in SSA. Key messages Effective strategies to improve blood pressure control among patients with chronic comorbidities are needed.
