Multidomain Hypertension-Mediated Organ Damage in Ghanaian Adults: Prevalence, Correlates, and Brachial-Ankle Pulse Wave Velocity Performance
Abstract
Background: Comprehensive assessment of hypertension-mediated organ damage (HMOD) across multiple organ systems in sub-Saharan Africa is limited. We assessed the prevalence and correlates of multidomain HMOD in a geographically diverse population in Ghanaian adult. Methods: This cross-sectional secondary analysis of the Ghana Heart Study, which included 1,106 adults aged [≥]18 years from four Ghanaian regions between September 2016 and March 2017. Multidomain HMOD was determined using a pre-specified 9-domain composite score [≥]2, using an ESH/ESC 2018 guideline-informed selection of HMOD domain with baPWV instead of carotid-femoral PWV (cfPWV), due to device unavailability, and a threshold of [≥]14 m/s which was derived from analysis within the cohort. LODO sensitivity analyses were used to address issues of predictor-outcome circularity. We used logistic regression models to examine association between each predictor and multidomain HMOD, adjusted for age, systolic blood pressure, body mass index, presence of dyslipidaemia and smoking status. We also performed receiver operating characteristic (ROC) analysis to determine correlates of multidomain HMOD and compare the discriminative ability of each predictor against the others. Results: The mean age of participants was 46.9{+/-}17.2 years of which 58% were females. Multidomain HMOD was observed in 21.3% (235/1,106; zero-imputation lower bound 21.2%) of participants studied. There was a marked increase in the prevalence of…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 1,106 participants or records.
