Sodium And Potassium Intake And Their Association With Hypertension Among Adults Aged 20-64 Years In Butajira Southern Ethiopia.

Background: Nutritional factors play an important role in regulation of blood pressure, andrndevelopment of hypertension. However, no studies have assessed the association betweenrndietary sodium and potassium intake and blood pressure in adults with no prior history ofrnhypertension in Ethiopia. rnObjectives: To evaluate Sodium and potassium intake and their association withrnhypertension among adults aged 20-64 years living in Butajira, Ethiopia, 2019. rnMethods: A community based cross-sectional study was conducted among 432 adults agedrn20-64 years living in Butajira, Ethiopia. Blood pressure, anthropometric indices and dietaryrnsodium and potassium were measured. Data on sodium and potassium intake were collectedrnusing two 24 hour recalls and usual intake was estimated using the national cancer instituternmethod. One-way analysis of variance was used to compare continuous variables, and Chisquarerntest wasrnusedrnto comparerncategoricalrnvariables.rnMultivariablernlinearrnregressionrnwasrnrnusedrntornassessrnthernassociationrnofrnsodium,rnpotassiumrnand sodium-to-potassiumrnratiornwithrnbloodrnrnpressure,rnandrnmultivariablernlogisticrnregressionrnwasrnusedrnto evaluaterntheirrnassociationrnwithrnhypertension.rnrnResults: The estimated mean (SE) usual intakes of dietary sodium, dietary potassium andrnsodium-to-potassium ratio were 3.2 ± 0.35 g/day, 2.1 ± 0.07g/day and 1.5 ± 0.14 respectively.rnUsual sodium intake and sodium-to-potassium ratio were associated positively with systolicrnand diastolic blood pressure. An inverse association was observed with usual potassiumrnintake but the association did not reach statistical significance.
