Predictors of Blood Lipid and Renal Function Screening among Adults in a Peri-Urban Community in Ghana: A Combined Logistic and Dominance Analysis Approach

Objective: Despite the critical role of screening in reducing the burden of non-communicable diseases (NCDs), its uptake remains low, particularly in peri-urban settings. This study aimed to identify and rank predictors of screening behaviors for blood lipid/cholesterol and renal function in a peri-urban community in Ghana. Methods: Secondary cross-sectional data from 136 adults aged 18–60, collected in January 2023, were analyzed. Associations and relative importance were examined using bootstrapped logistic regression and dominance analysis models. Results: Multivariate logistic regression analysis identified age (35-60 years) (aOR:7.6, 95% CI: 1.2–50.6) and employment status (aOR:4.4, 95% CI: 1.1–17.6) as significant predictors of renal screening. For blood lipid screening, significant predictors included body mass index (BMI) screening (aOR:3.6, 95% CI: 1.4–9.1) and diploma-level education (aOR:5.4, 95% CI: 1.3–21.8). Dominance analysis, which assesses the relative importance of predictors, revealed that age, blood glucose screening, and employment were the most important predictors for renal screening. In contrast, BMI and a history of raised blood pressure were the leading predictors for blood lipid screening. Conclusions: These findings highlight the need for targeted health promotion strategies that integrate comprehensive screening packages within broader health services, addressing the specific needs of various educational and occupational groups. Enhanced public health interventions could improve screening rates and contribute to better management of NCDs in peri-urban settings.
