Prevalence and correlates of chronic kidney disease among civil servants in Bayelsa state, Nigeria

Abstract

Introduction: Chronic kidney disease (CKD) has become a public health problem with rising incidence and prevalence world-wide. Despite the fact that Sub-Saharan Africa, including Nigeria appears to be badly hit by this epidemic, there is a paucity of data on CKD prevalence in these regions and where data exists, they are mostly hospital-based.
Objectives: The present study was carried out to determine the prevalence and correlates of CKD in an urban civil service population in Bayelsa State, Nigeria.
Materials and Methods: A total of 179 civil servants in the Bayelsa State secretariat were screened for CKD during the World Kidney Day on March 2012. CKD was defined as estimated glomerular filtration rate <60 ml/min/1.73 m2 body surface area and/or proteinuria. Socio-demographic data was obtained using interviewer.administered semi-structured questionnaire while anthropometric measurements were taken. Blood pressure (BP), urinalysis, serum urea and creatinine were also assessed.
Results: The prevalence of CKD in the study was 7.8%. Age >50 years was associated with CKD in univariate analysis but none of age, gender, body mass index, BP or hyperglycemia independently predicted it.
Conclusion: The prevalence of CKD among Nigerian civil servants was fairly high and was associated with advancing age. Routine screening for CKD in this population is recommended.
