[PS 03-19] PREVALENCE AND ATTRIBUTABLE FACTORS OF HYPERTENSION IN KHARTOUM LOCALITY POPULATION, SUDAN, 2014

Objective: To estimate prevalence of hypertension (HTN) and associated risk factors among Khartoum locality population. Design and method: Descriptive community based study conducted in Khartoum locality. A sample of 587 individuals’ age 18 years and above was enrolled in the study. Multistage cluster Sampling was used. Data collection tools were; a structured interview using questionnaire, blood pressure measurement was performed and body mass Index (BMI) was calculated. Data Analysis was done using STATA statistical software, description of data using frequency and percentages for qualitative data and median for quantitative data. Association between outcome and independent variable was estimated using chi-squire, p-value ⩽0.05 considered significant. Ethical approval was obtained from Sudan Medical Specialization Board ethical committee. All participants signed an informed consent. Results: Response rate was 85%., Male to female ratio was 1:2. Two thirds of the study population was married. University and postgraduates constituted (45.8%). Nearly half (48.4%) of the study population were unemployed. Prevalence of HTN and Pre- HTN was found to be 36.7% and 26.6% respectively. HTN is significantly related to age where 5%, 39% and 66% of the hypertensive were recorded in the age groups ⩽25, 25–64 and ≥65year respectively (p-value ⩽0.000). The prevalence of overweight and obesity was 28% and 36% respectively. BMI is positively related to HTN; HTN prevalence increases as BMI increases (P-value ⩽0.000). Family history is positively related to HTN (P ⩽ 0.000); also marital status where 78.25% of the married individuals were hypertensive (P-value ⩽0.000). There is a positive relation between salt consumption and HTN, about 60% of the hypertensive did not pay attention to the amount of salt in their food (P-value ⩽ 0.003), also physical inactivity is positively related to HTN (P-value ⩽0.019). Conclusions: HTN and pre-hypertension were high among Khartoum locality population. Age obesity, family history, salt consumption and physical inactivity were the main risk factors.
