Prevalence and Predictors of Chronic Kidney Disease in a Semiurban Community in Lagos

Abstract EN

Background and Objectives.

The prevalence of noncommunicable diseases like chronic kidney disease is on the rise in third-world countries.

In Nigeria and most sub-Saharan African countries, there is dearth of community-based studies on prevalence and predictors of chronic kidney disease, prompting us to undertake this study.

Materials and Methods.

This was a cross-sectional study, aimed at ascertaining the prevalence and predictors of chronic kidney disease (CKD) in a semiurban community in Lagos, Southwest Nigeria.

The study’s subjects were recruited from Agbowa community in Ikosi-Ejirin Local Council Development Area of Lagos state.

The community was randomly selected.

Questionnaires were used to obtain relevant information from the subjects.

Body mass index, anthropometric measurements, and other relevant data were also collected.

Results.

CKD was observed in 30 subjects given prevalence of 7.5% in the community.

Nine out of the 30 subjects (30%) with CKD were males, while 21 (70%) subjects were females.

The prevalence of CKD was significantly higher in the female population.

28 of the subjects with CKD were in stage 3, while 2 of the subjects with CKD were in stage 4.

Age, hypertension, and hyperuricemia were significantly associated with CKD.

Using multiple logistic regression analysis, 4 variables predicted CKD in the study population.

These were age (P =0.01, OR = 0.

274, CI = 0.102 – 0.739), hypertension (p = 0.011, OR = 0.

320, CI = 0.132 – 0.773), hyperuricemia (p=0.001, OR = 0.195, CI =0.083 – 0.461), and female sex (p = 0.009, OR = 3.775, CI = 1.401 – 10.17).

Conclusion.

The prevalence of CKD in the population is low compared with other studies from other parts of the country, and the predictors included age, hypertension, hyperuricemia, and female gender.

This is the first community-based study in Nigeria to identify hyperuricemia as a risk factor for chronic kidney disease in the country.
