Screening for chronic kidney disease and its risk factors in Oghara, Nigeria: a World Kidney Day 2014 report

ABSTRACT

Background: The risk factors associated with CKD such as hypertension, diabetes and obesity remain prevalent globally, resulting in a high prevalence of CKD especially in developing countries. Screening for CKD and its' risk factors is recommended for high-risk population. This study aimed to determine the prevalence and risk factors of CKD in a semiurban community in Nigeria.Methods: A cross-sectional survey was conducted in the teaching hospital premises at Oghara, after a world kidney day (WKD) health awareness campaign was undertaken in the community. A total of 135 subjects were interviewed and the following measurements were performed blood pressure, body mass index, blood glucose, dipstick urinalysis, serum creatinine and estimation of glomerular filtration rate (GFR) using CKDEPI.Results: Mean age was 40 ± 13 years and 69.6% of participants were young. Male to female ratio was 14. The prevalence of proteinuria was 4.4% while 10.7% of all subjects had CKD (GFR <60ml/min). Although 11.1% of participants were known hypertensives only 6.7% had high blood pressure on screening. Other risk factors identified were Diabetes mellitus (10.3%), family of history of hypertension (14.1%), family of history of diabetes (9.6%), family of history CKD (1.5%) and obesity (11.9%). Proteinuria, diabetes and family history of hypertension were significantly associated with CKD.Conclusions: CKD and its risk factors are common in the population.Dipstick proteinuria remains a useful and significant indicator of CKD.Community screening for the risk factors of CKD in developing countries is realistic and should be encouraged as a public health priority
