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

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 m 2 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.
