Abstract
Background: Dyslipidaemia significantly contributes to cardiovascular complications in hypertensive patients, yet its pattern and associated factors remain understudied in Nigeria. Identifying high-risk subgroups is essential for targeted intervention.
Objective: The study aimed to determine the prevalence and sociodemographic predictors of dyslipidaemia among hypertensive adults receiving care at the University of Benin Teaching Hospital (UBTH), Benin City, Nigeria.
Methods: A retrospective cross-sectional study was conducted among 826 hypertensive adults attending UBTH. Data were extracted from medical records, including age, sex, marital status, education level, body weight, blood pressure, glycemic status, and fasting lipid profile. Descriptive statistics were used to summarise findings. Chi-square and independent t-tests examined associations, while multivariate logistic regression identified independent predictors. Significance was set at P < .05. Analyses were conducted using SPSS version 27.
Results: The prevalence of dyslipidaemia was 66.9%, with elevated total cholesterol (38.4%) being the most common abnormality, followed by high LDL-C (33.5%) and low HDL-C (28.1%). Participants with no formal education had over threefold increased odds of dyslipidaemia compared to those with tertiary education. Being widowed or divorced also increased the odds significantly. Prediabetes and elevated weight were independent predictors. Age, sex, and systolic/diastolic blood pressure were not significant factors.
Conclusion: Dyslipidaemia is highly prevalent among hypertensive patients at UBTH and is strongly linked to low educational attainment, altered marital status, prediabetes, and higher body weight. These findings highlight the importance of integrating lipid screening and lifestyle counselling into hypertension management, especially for socioeconomically vulnerable groups.
