Prevalence and factors associated with suboptimal blood pressure among ambulatory patients with diabetic kidney disease attending a tertiary hospital in Uganda

Abstract

Background: Kidney failure prevalence is increasing among diabetic kidney disease (DKD) patients in low-income countries. Suboptimal blood pressure (BP) drives kidney failure and mortality. The burden of suboptimal BP and its associated factors among these patients are not well documented. Objectives: To determine the prevalence of suboptimal BP and associated factors among those with DKD attending Kiruddu National Referral Hospital. Methods: In this cross-sectional study, recruited participants were screened for DKD using urine dipsticks from 6th May 2020 to 15th July 2020. A pretested questionnaire was administered, BP, height and weight were measured. Suboptimal BP was defined as systolic BP > 130mmHg and or diastolic BP > 80mmHg. A Poisson regression model analysed the associated factors. Results: 250 participants with DKD, mean age of 52(11) years were included of whom 199 (79.6%) were female. Suboptimal BP prevalence was 84.4%, associated with past (p = 0.04) and current (p < 0.001) alcohol use, overweight (p < 0.001) and obesity (p < 0.001), wage earning (p < 0.001) and professionals (p = 0.048). Conclusion: The prevalence of suboptimal BP was high among the overweight, obese, unemployed and alcohol users. Thus, there is a need for better BP control interventions Keywords: Blood pressure; diabetes mellitus; kidney disease.
