PS 08-49 AGE SPECIFIC PREVALENCE OF HYPERTENSION, SOCIO-DEMOGRAPHIC AND BEHAVIORAL CHARACTERISTICS OF END STAGE RENAL DISEASE PATIENTS ON REGULAR HAEMODIAYSIS IN A DEVELOPING A COUNTRY.

Abstract

Objective: To identify the Age Specific Prevalence of hypertension (HTN), Socio-demographic and Behavioral characteristics among ESRD undergoing regular hemodialysis (HD), to assess whether there is a difference between the defined age groups and the effect size estimate. Design and Method: A cross-sectional hospital based study was performed in Al-Academy Teaching Hospital hemodialysis center involving 122 patients on regular dialysis. HTN is defined as an average systolic blood pressure (SBP) of ≥ 140 mmHg or an average diastolic blood pressure (DBP) of ≥90 mmHg, or anyone who is currently taking antihypertensive medications even with normal blood pressure values at the time of measurement. The patients were divided into 3 groups, 18–45, 46–65 and older than 65 years. Normality testing was done with Shapiro-Wilk W Test. The difference between the groups was assessed using Kruskal–Wallis one-way analysis of variance and finally the effect size estimate was calculated. Results: In the first group, 69% were hypertensive with a mean of 145 +/− 19.184 Standard deviation (SD) and 90.31 +/− 14.022 (SD) for SBP and DBP respectively. For the second group, 55.1% of them were hypertensive with a mean of 138.90 +/− 25.936 SD and 81.71 +/− 14.911 SD for the SBP and DBP respectively. Finally, in the last group, 51.6% were hypertensive with a mean of 140.97 +/− 25.586 SD and 75.68 +/− 12.045 SD for the SBP and DBP respectively. Kruskal–Wallis test demonstrated a difference between the DBP readings (P value < 0.05) but no difference between the SBP readings (P value =0.28) with an effect size estimate of 13.85% for the DBP. Conclusions: The majority of the patients were hypertensive with a difference between the groups in the DBP (P value < 0.05). For the DBP values, 13.85% of the variability in the rank scores is being accounted for by the groups specified.
