Abstract


Abstrak

Hipertensi merupakan salah satu penyakit degeneratif yang prevalensinya semakin meningkat setiap tahun. Salah satu faktor yang mempengaruhi tekanan darah pada pasien hipertensi adalah asupan protein dan kalium. Tujuan penelitian ini untuk mengetahui hubungan asupan protein dan asupan kalium terhadap tekanan darah pasien hipertensi rawat jalan di Puskesmas Bareng Kota Malang. Metode penelitian yang digunakan dalam penelitian ini adalah cross sectional. Sampel dipilih dengan cara purposive sampling sebanyak 60 orang pasien hipertensi yang ada diwilayah kerja Puskesmas Bareng dan sudah memenuhi kriteria inklusi. Uji statistik yang digunakan adalah uji korelasi Spearman dengan variabel yang diukur yaitu asupan protein, asupan kalium, tekanan darah sistolik, dan tekanan darah diastolik. Hasil analisis bivariat menunjukkan ada hubungan yang signifikan antara asupan protein dengan tekanan darah sistolik (rs= -0,407, p=0,001) dan tekanan darah diastolik (rs = -0,519, p=0,000) dengan arah korelasi negatif. Asupan kalium berhubungan dengan tekanan darah sistolik (rs= -0,518, p=0,000) dan tekanan darah diastolik (rs= -0,419, p=0,000) dengan arah korelasi negatif. Kesimpulan dari penelitian ini adalah asupan protein dan asupan kalium berhubungan signifikan dengan penurunan tekanan darah pada pasien hipertensi.

Kata kunci: protein, kalium, tekanan darah, hipertensi.

 

Abstract

Hypertension is one of the degenerative diseases whose prevalence experiences an increase every year. One of the factors that influence blood pressure in hypertensive patients is protein and potassium intake. The purpose of this study was to determine the relationship of protein intake and potassium intake on blood pressure in hypertensive outpatient in community health centers of Bareng Malang. The method of this study was cross – sectional study. Samples were selected by purposive sampling with 60 hypertensive patients who have already met the inclusion criteria. Statistical test used Spearman correlation test with a variable that measured protein intake, potassium intake, systolic and diastolic blood pressure. Bivariate test indicates that a protein intake was related significantly associated to systolic blood pressure (rs = -0,407, p = 0,001) and diastolic blood pressure (rs = -0,519, p = 0,000) leading to negative correlation. Potassium intake had a significant correlation to systolic blood pressure (rs = -0518, p=0,000) and diastolic blood pressure (rs= -0419, p=0.000) leading to negative correlation. It was then concluded from thisresearch that protein and potassium intake was associated with systolic and diastolic blood pressure.

Keywords: protein, potassium, blood pressure, hypertension.
