Risk factors for chronic kidney disease in the community: A decade of outreach in Kenya

Abstract

Problem Considered

Burden of chronic kidney disease (CKD) is increasing globally. We present chart analysis of data obtained during community screening for kidney disease between 2011-2021 in various parts of Kenya with objectives to document and stratify risks for kidney disease in the community.

Methods

This was a descriptive analysis charts. Age, sex, individuals’ data on smoking, diabetes, hypertension, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), random blood sugar (RBS), dipstick urinalysis, as well as family history of CKD, hypertension and diabetes were analysed. Continuous variables had mean, standard deviation (SD), median and interquartile range (IQR) while frequencies for categorical variables were calculated.

Results

About 10,675 individuals were analysed. Median age was 41 years (25 – 53). Females were 6,092(57.1%). Known hypertensive, diabetic and smokers were 2,028(19.0%), 881(8.3%) and 523(4.9%) respectively. Family history of hypertension, diabetes and CKD was reported by 3,810(35.7%), 2,751(25.8%) and 978(9.2%) respectively. In 10,121(94.8%) RBS was tested. About 470(4.6%) had RBS < 4.0 mmol/L, 9,298(91.9%) 4.0-11.0 mmol/L while 368(3.6%) was > 11.0 mmol/L. Incidental hyperglycemia was in129 (1.2%). Median SBP and DBP was 128 mmHg (116-143) and 78 mmHg (70 – 87) respectively. Mean BMI was 25.96±5.27 kg/m2. Subgroups with diabetes and hypertension had higher mean age, SBP, DBP and RBS, family history of hypertension, diabetes and CKD.

Conclusion

Burden of risks for CKD in the community high. Blood sugar and blood pressure controls were suboptimal. There was concordance in the findings of hypotensive, diabetic and family history of similar conditions.
