Awareness, knowledge and perception of chronic kidney disease in a rural community of South-West Nigeria

Abstract

Background: Awareness and education on kidney disease impact on its effective management and will reduce the significant economic and public health burden. Knowledge of CKD and risk factors increases the perception of being at high risk and increasing health seeking behavior. We conducted a cross-sectional descriptive study to assess the level of awareness, knowledge and conventional risk factors of CKD in the community to strategize on preventive modalities using the information gathered from this population.

Methods: We used a pretested structured questionnaire to draw information on sociodemography, knowledge and risk factors of CKD from 563 residents aged >18 years.

Results: A total of 454 residents completed this study, mainly farmers, with a mean age of 45.8 ± 19.0 years and male: female ratio of 0.8:1. Only 33.7% had heard of kidney disease with 59.3% from the media and 35.3% from health workers; the level of knowledge of CKD was good in 27.1%. The majority (67.0%) do not know the correct location of the kidneys. Only 10.6% could mention at least one function of the kidneys with only 24.5% agreeing that NSAIDs can cause kidney disease. A laboratory test for kidney function was known by 4.4%; 45.9% and 47.8% believe that CKD can be cured by spiritual means and herbal concoctions respectively. Only 11.1% agreed that CKD can be hereditary. Abdominal obesity and cigarette smoking were seen in 14.6% and 16.6% respectively. Hypertension was seen in 26.5% while 17.8% actually knew they were hypertensive. Diabetes mellitus was found in 3.4%. None of the patients with CKD who had diabetes or hypertension was aware of kidney disease.

Conclusion: There are a misconception and low level of awareness and knowledge of CKD, including those with risk factors, in the community. Efforts should be made to create awareness and educate people on CKD and prevention of its risk factors.
