Socioeconomic determinants of knowledge of kidney disease among residents in Nigerian communities in Lagos state, Nigeria

الملخص EN

Objectives: We sought to estimate the knowledge, sociodemographic determinants, and riskinducing lifestyles of kidney disease (KD) among Nigerians living in Lagos State.

Methods: We conducted a cross-sectional descriptive study to assess the level of knowledge of KD and its associated sociodemographic factors of individuals living in urban and semi-urban communities of Lagos State, Nigeria.

It is hoped that the results of this study will help to inform preventive modalities.

We used a pretested, structured questionnaire to draw information from 1171 Nigerians aged ≥ 15 years.

Results: The mean age of respondents was 33.5±11.1 years.

In our cohort, 72.4% of respondents were knowledgeable of KD, with media as their major source of information (41.6%).

Knowledge of KD was significantly associated with age (p = 0.044), education (p < 0.001), marital status (p < 0.001), and place of residence (p = 0.048).

The established KD risk-inducing lifestyle factors were habitual use of herbal supplements, significant alcohol consumption, and diabetes (p < 0.050).

Significant predictors of knowledge of KD included primary education (Odds ratio (OR) = 0.367, 95% confidence interval (CI): 0.11–1.22; p =0.102), secondary education (OR = 0.296, 95% CI: 0.17–0.51; p < 0.001), Igbo ethnic group (OR = 1.471, 95% CI: 0.99–2.17; p = 0.047), and place of residence (OR = 1.332, 95% CI: 1.00–1.77; p = 0.048).

Age 30–39 years (OR = 0.749, 95% CI: 0.48–1.18; p = 0.214), 40–49 years (OR = 1.083, 95% CI: 0.69–1.69; p = 0.727), and not working (OR = 1.178, 95% CI: 0.88–1.57; p < 0.269) were non-significant predictors of knowledge of KD.

Conclusions: Our cohort had inadequate knowledge of linking risk-inducing lifestyles to KD development.

Effective measures and efforts should be made to create awareness and educate the general population on KD and prevention measures related to risk-inducing lifestyles to reduce the burden of KD among Nigerians.
