Abstract

RELATIONSHIP BETWEEN TOTAL CHOLESTEROL LEVELS AND BODY MASS INDEX (BMI) WITH BLOOD PRESSURE IN THE ELDERLY IN SABA VILLAGE, BLAHBATUH DISTRICT, GIANYAR REGENCY ABSTRACT Background: Hypertension is a common health problem among the elderly and is often unnoticed due to minimal symptoms. High cholesterol levels can lead to atherosclerosis, while a high Body Mass Index (BMI) can increase the workload of the heart, thereby triggering increased blood pressure. Objective: To determine the relationship between total cholesterol levels and BMI with blood pressure among the elderly in Saba Village, Blahbatuh District, Gianyar Regency.Methods: This study used a quantitative method with an analytical observational design and a cross-sectional approach involving 37 elderly respondents selected through purposive sampling. Results: The results showed that most respondents were aged 60–69 years (81.08%), predominantly female (54%), had borderline to high cholesterol levels (51%), were categorized as overweight to obese (68%), and had blood pressure ranging from prehypertension to stage 2 hypertension (68%). The Chi-Square Fisher Exact test with Monte Carlo approach showed a relationship between total cholesterol levels and BMI with blood pressure (p = 0.000; p < 0.05), with a strong correlation (Cramer’s V = 0.724). Conclusion: There is a strong relationship between total cholesterol levels and BMI with blood pressure among the elderly. It is recommended that the elderly routinely monitor their health, maintain a healthy diet and physical activity, and that future researchers include additional variables with larger sample sizes for more comprehensive results. Keywords: total cholesterol; bmi ; blood pressure HUBUNGAN KADAR KOLESTEROL TOTAL DAN INDEKS MASSA TUBUH (IMT) DENGAN TEKANAN DARAH PADA LANSIA DI DESA SABA KECAMATAN BLAHBATUH KABUPATEN GIANYAR ABSTRAK Latar belakang: Hipertensi merupakan masalah kesehatan yang sering terjadi pada lansia dan kerap tidak disadari karena minimnya gejala. Kadar kolesterol yang tinggi dapat menyebabkan aterosklerosis, sedangkan indeks massa tubuh (IMT) yang tinggi dapat meningkatkan beban kerja jantung sehingga memicu peningkatan tekanan darah.Tujuan : Mengetahui hubungan kadar kolesterol total dan IMT dengan tekanan darah pada lansia di Desa Saba, Kecamatan Blahbatuh, Kabupaten Gianyar. Metode: penelitian kuantitatif dengan desain observasional analitik pendekatan cross-sectional pada 37 lansia dengan teknik purposive sampling. Hasil: Hasil penelitian menunjukkan sebagian besar responden berusia 60–69 tahun (81,08%), didominasi perempuan (54%), memiliki kadar kolesterol ambang batas hingga tinggi (51%), IMT overweight hingga obesitas (68%), serta tekanan darah prehipertensi hingga hipertensi derajat 2 (68%). Uji Chi Square Fisher Exact Monte Carlo menunjukkan terdapat hubungan antara kadar kolesterol total dan IMT dengan tekanan darah (p = 0,000; p < 0,05) dengan kekuatan hubungan kuat (Cramer’s V = 0,724). Simpulan: terdapat hubungan antara kadar kolesterol total dan IMT dengan tekanan darah pada lansia dengan kekuatan hubungan kuat. Disarankan lansia melakukan pemantauan rutin, menjaga pola makan dan aktivitas fisik, serta peneliti selanjutnya menambahkan variabel lain dengan sampel lebih luas. Kata kunci: kolesterol total; imt; tekanan darah
