Factors predicting blood pressure control among patients with non-dialysis chronic kidney disease in Myanmar

Abstract

This correlational predictive study aimed to examine the blood pressure (BP) control rate and predictive power of sodium consumption behavior, family support, health professional support, chronic kidney disease (CKD) severity, and gender on BP control among patients with non-dialysis CKD in Myanmar. The study was conducted with 150 adults, both males and females, in the Out-patient Clinics of Medical Unit II and Renal Medical Unit, Mandalay General Hospital, Mandalay, Myanmar. Convenience sampling method was used for the recruitment of the sample. The data were collected by measuring BP and using the questionnaires: Demographic and Clinical Characteristic Data Record Form, Sodium Consumption Behavior Questionnaire, Family-Friends Support Subscale, and Doctor-Health Care Team Support Subscale of Chronic Illness Resources Survey (CIRS). Descriptive statistics and binary logistic regression were applied for data analysis.The results revealed that the participants were capable of achieving the BP target by 44%. The mean age of the sample was 58.35 years (SD=12.64) and 58% of the sample were men. Two-fifths of the sample (40%) were in CKD stage 3. Majority of the participants had low sodium consumption behavior (Mean=31.55,SD=4.83). The mean scores of family support and health professional support were found to be fair with the means of 3.12 (SD=0.69) and 2.88 (SD=0.57), respectively. In binary logistic regression analysis, sodium consumption behavior, family support, health professional support, CKD severity, and gender jointly accounted for 41% of the variance in BP control. Sodium consumption behavior (OR=7.191,95%CI:2.892−17.882,p<0.001), family support (OR=6.068,95%CI:2.330−15.804,p<0.001), and CKD severity (OR=5.865,95%CI:2.134−16.123,p=0.001) were the significant predictors of BP control.Family-based interventions regarding practices of low sodium intake should be undertaken for improving BP control in Myanmar patients with non-dialysis CKD. Moreover, therapeutic interventions should be focused on advanced CKD stage patients.
