Epidemiology of chronic kidney disease in northern region of Senegal: a community-based study in 2012.

INTRODUCTION: Chronic kidney disease (CKD) is an emerging worldwide epidemic but few data are available in African populations. We aimed to assess prevalence of CKD in adult populations of Saint-Louis (northern Senegal). METHODS: In a population-based survey between January and May 2012, we included 1,037 adults aged=18 years living in Saint-Louis. Socio-demographical, clinical and biological data were collected during household visits. Serum creatinine was measured by Jaffé method. We estimated glomerular filtration rate (eGFR) using the 4-variables MDRD equation and CKD was defined by eGFR<60 mL/min/1.73 m2 and/or albuminuria>1g/L. A multivariate logistic regression was performed to identify factors associated with CKD. RESULTS: Mean participants' age was 47.9±16.9 years (18-87) and sex-ratio was 0.52. Majority of participants lived in urban areas (55.3% rural) and had school education (65.6%). Overall prevalences of hypertension, diabetes and obesity were 39.1%, 12.7% and 23.4% respectively. Prevalence of CKD was 4.9% (95% CI=3.5-6.2) and 0.9% had GFR<30 mL/min/1.73 m2. Albuminuria>1g/l was found in 3.5% of people. CKD was significantly more frequent among hypertensive patients compared to normotensive participants. Only 23% of patients were aware of their disease before the survey. After multivariate logistic analysis, presence of CKD was significantly associated with hypertension (OR=1.12, p=0.02) and age (OR=1.03, p=0.02). CONCLUSION: CKD is frequent in adult population living Northern Senegal. Main associated factors are hypertension and age. Prevention strategy is urgently needed to raise awareness and promote CKD detection and early treatment in both urban and rural areas.

Prevalence of chronic kidney disease and associated factors in senegalese populations: a community-based study in saint-louis.

BACKGROUND: Chronic kidney disease (CKD) is an emerging worldwide epidemic but littledata concerning African populations are available. OBJECTIVES: We aimed to assess prevalence of CKD in adult populations of Saint-Louis, northern Senegal. PATIENTS AND METHODS: In a population-based survey between January and May 2012, we included 1037 adults ≥ 18 years of age who resided in Saint-Louis. Socio-demographic, clinical, and biologic data were collected during household visits. Serum creatinine was measured by Jaffé method. We estimated glomerular filtration rate (eGFR) using the four-variable Modification of Diet in Renal Disease (MDRD) equation and CKD was defined by eGFR< 60 mL/min/1.73 m(2) and/or albuminuria > 1 g/L. A multivariate logistic regression was performed to identify factors associated with CKD. RESULTS: The mean of participants' age was 47.9 ± 16.9 years (range, 18-87) and sex ratio (male to female) was 0.52. Majority of participants lived in urban areas (55.3%) and had school education (65.6%). Hypertension, diabetes, and obesity were present respectively in 39.1%, 12.7%, and 23.4% of participants. Overall CKD prevalence was 4.9% (95% CI, 3.5-6.2) with eGFR< 30 mL/min/1.73 m(2) in 0.9%. Albuminuria > 1 g/L was found in 3.5% of patients. CKD was significantly more frequent among hypertensive patients in comparison with normotensive ones. Risk factors associated with CKD were hypertension (12% of risk excess) and age (3% of risk excess). CONCLUSIONS: CKD is frequent in adult population living in Northern Senegal. Main associated factors are hypertension and age. Prevention strategies are urgently needed to raise public awareness and promote early CKD detection and treatment in both urban and rural areas.

Dyslipidemia, obesity and other cardiovascular risk factors in the adult population in Senegal.

INTRODUCTION: According to the WHO, 50% of deaths worldwide (40.1% in developing countries) are due to chronic non-communicable diseases (NCDs). Of these chronic NCDs, cardiovascular diseases remain the leading cause of death and disability in developed countries. The Framingham study has shown the importance of hypercholesterolemia as a primary risk factor. In Senegal, the epidemiology of dyslipidemia and obesity are still poorly understood due to the lack of comprehensive studies on their impact on the general population. This motivated this study to look into the key epidemiologic and socio-demographic determinants of these risk factors. METHODS: It was a cross-sectional descriptive epidemiological survey which included 1037 individuals selected by cluster sampling. Data were collected using a questionnaire following the WHO STEPwise approach. Socio-demographic, health and biomedical variables were collected. P value <0.05 was considered to be statistically significant. RESULTS: The average age was 48 years with a female predominance (M: F of 0.6). The literacy rate was 65.2% and 44.7% of participants were from rural areas. The prevalence of hypercholesterolemia, hyperLDLemia, hypoHDLemia, hypertriglyceridemia and mixed hyperlipidemia were 56%, 22.5%, 12.4%, 7.11% and 1.9% respectively. One in four was obese (BMI> 30kg/m2) and 34.8% had abdominal obesity. The main factors significantly associated with dyslipidemia were obesity, urban dwelling, physical inactivity and a family history of dyslipidemia. CONCLUSION: The prevalence of dyslipidemia, obesity and other risk factors in the population was high needing immediate care for those affected and implementation of prevention strategies.
