Latar Belakang: Diare pada lanjut usia merupakan masalah kesehatan signifikan di Jawa Barat. Determinan pada kelompok usia transisi 60–75 tahun belum banyak dikaji. Tujuan: Menganalisis determinan kejadian diare pada penduduk usia 60–75 tahun berdasarkan karakteristik individu, faktor lingkungan, dan faktor perilaku menggunakan data SKI 2023. Metode: Desain cross-sectional dengan sampel 5.169 responden. Analisis menggunakan uji chi-square dan regresi logistik ganda. Hasil: Prevalensi diare sebesar 3,3%. Analisis bivariat menunjukkan hubungan signifikan antara jenis kelamin (p=0,001; OR=1,69), pendidikan (p=0,010; OR=1,77), tempat tinggal (p=0,016; OR=1,55), sumber air minum (p=0,037; OR=1,88), kualitas fisik air minum (p=0,046; OR=1,88), pengelolaan sampah (p=0,021; OR=1,44), fasilitas cuci tangan (p=0,002; OR=1,66), dan perilaku cuci tangan pakai sabun (p=0,034; OR=1,76) dengan kejadian diare. Analisis multivariat menunjukkan jenis kelamin (perempuan) sebagai determinan paling dominan (aOR=1,723; 95% CI:1,251–2,374; p=0,001). Kesimpulan: Jenis kelamin perempuan merupakan faktor paling dominan terhadap kejadian diare pada penduduk usia 60–75 tahun di Provinsi Jawa Barat, diikuti oleh ketersediaan fasilitas cuci tangan yang memadai.

Background: Diarrhea in the elderly is a significant health problem in West Java. Determinants among the transitional age group of 60–75 years have not been extensively studied. Objective: To analyze the determinants of diarrhea among the population aged 60–75 years based on individual characteristics, environmental factors, and behavioral factors using data from the 2023 Indonesian Health Survey. Methods: A cross-sectional design was employed with a sample of 5,169 respondents. Data were analyzed using chi-square tests and multiple logistic regression. Results: The prevalence of diarrhea was 3.3%. Bivariate analysis showed significant associations between diarrhea and sex (p=0.001; OR=1.69), education (p=0.010; OR=1.77), residence (p=0.016; OR=1.55), drinking water source (p=0.037; OR=1.88), physical quality of drinking water (p=0.046; OR=1.88), waste management (p=0.021; OR=1.44), handwashing facilities (p=0.002; OR=1.66), and handwashing with soap behavior (p=0.034; OR=1.76). Multivariate analysis revealed that female sex was the most dominant determinant (aOR=1.723; 95% CI: 1.251–2.374; p=0.001). Conclusion: Female sex is the most dominant factor associated with diarrhea among the population aged 60–75 years in West Java Province, followed by the availability of adequate handwashing facilities.
