Judul: Implementation of binary logistic regression and dominance analysis for analyzing influential factors against hypertension (case study: Gunung Kidul)
Abstrak: Penyakit hipertensi sering disebut sebagai penyakit yang perlahan-lahan mematikan karena tidak ada tanda-tanda bahwa seseorang menderita penyakit tersebut. Penyakit hipertensi telah mematikan 9.4 juta warga dunia setiap tahunnya. Pada tahun 2025 mendatang, diperkirakan sekitar 29% warga dunia terkena hipertensi. Menurut WHO bahwa 40% penduduk negara ekonomi berkembang menderita penyakit hipertensi. Berdasarkan hasil penelitian dari Riset Kesehataan Dasar 2007 dengan menggunakan analisis regresi logistik biner menunjukkan bahwa terdapat empat faktor yang berpengaruh terhadap hipertensi yaitu umur, Indeks Massa Tubuh, frekuensi makanan dibakar, dan frekuensi makanan berlemak. Analisis regresi logistik kemudian dilanjutkan dengan analisis dominan untuk mengetahui masing-masing peringkat peubah penjelas terhadap hipertensi. Berdasarkan hasil analisis dominan menunjukkan bahwa peubah umur menduduki sebagai peringkat pertama penyebab menderita hipertensi. Kata kunci : analisis dominan, analisis regresi logistik biner, hipertensi, Hypertension is often called the silent disease because there are no signs that a person suffering from the disease. Hypertension has been shut off 9.4 million citizens of the world each year. In 2025, an estimated 29% of people in the world affected by hypertension. According to WHO, 40% of developing economies suffer from hypertension. Based on the results of analysis of binary logistic regression, it can be seen that the four causes of hypertension. There are age, body mass index, frequency of burned food, and frequency of fatty foods. After that, using dominance analysis to determine the main factors causing hypertension. By using dominance analysis, variables of age as a major risk factor of hypertension. Keywords: binary logistic regression, dominance analysis, hypertension

Judul: Faktor Risiko Hipertensi Pada Empat Kabupaten/Kota Dengan Prevalensi Hipertensi Tertinggi Di Jawa Dan Sumatera
Abstrak: Hypertension is a common public health problem that occur both of developed and developing countries. Increasing prevalence of hypertension independently associated with diet and lifestyle. Untreated hypertension leads to many degenerative diseases, including renal disease, congestive heart failure and peripheral vascular disease. Therefore the purpose of this study is to examine factors that can be protective and enhance hypertension prevalence, so that population can save their blood pressure (BP) by preventive and rehabilitative methodes. This study is a cross-sectional analysis in 5 104 subjects aged 18-97 y, consist of 2 491 males and 2 613 females. Data on Body Mass Index (BMI), BP, and other background characteristics of study partisipant were generated using the Riset Kesehatan Dasar (Riskesdas) 2007, at four demographics surveillance sites in Kuantan Singingi and Rokan Hilir (Riau Island), Wonogiri and Salatiga (Central Java). Hypertension was define as SBP≥140 mmHg or DBP≥90 mmHg, with adaptation of the recent JNC-7 definitions. Multiple logistic regression analyses were carried out to determine the odds of hypertension across the whole characteristic, while controlling for possible confounding. A high prevalence of hypertension was noted among four regions population in Kuantan Singingi (48.8%), Rokan Hilir (49.8%), Wonogiri (50.7%) and Salatiga (47.0%). The risk factor which can be reduce hypertension prevalence are ages 40-60 y (OR=0.229) and >60 y (OR=0.501), didn’t do middle physical activity (OR=0.814), didn’t do walking or ride bicycle (OR=0.744), underweight (OR=0.544) and overweight (OR=0.372). While the risk factor which can be enhance hypertension prevalence are education junior and senior high school (OR=1.292) and eating much salty foods (OR=1.258).
