Latar belakang. Infeksi merupakan penyebab terbanyak kematian bayi baru lahir dan salah satunya disebabkanoleh infeksi tali pusat (omfalitis). Untuk mencegah timbulnya omfalitis bermacam antiseptik atauantimikroba sudah digunakan secara luas. Rekomendasi pemilihan regimen perawatan harus didasarkanpola kolonisasi kuman di institusi tersebut. Badan Kesehatan dunia WHO dan AAP merekomendasikanperawatan tali pusat cara kering tanpa antiseptik ataupun antimikroba.Tujuan. Mengetahui pola kolonisasi kuman, kejadian omfalitis, dan lama puput tali pusat pada regimenperawatan dengan alkohol 70%, povidon iodin 10%, dan cara kering di RS Dr. M. Djamil Padang.Metode. Penelitian klinis eksperimental di Ruang Rawat Kebidanan dan Rawat Gabung RS dr. M. Djamilselama April hingga Agustus 2009. Bayi yang memenuhi kriteria penelitian dirandomisasi untuk mendapatkansatu metode perawatan tali pusat dengan alkohol 70%, povidon iodin 10%, atau cara kering. Swabumbilikal untuk biakan kuman dilakukan di rumah sakit saat bayi berusia 48-72 jam. Bayi diamati sampaitali pusat puput. Analisis data dengan uji chi-square dan Fischer exact.Hasil. Jumlah bayi yang diteliti 147, masing-masing kelompok terdiri dari 49 bayi. Hasil biakan ditemukanpertumbuhan kuman 97,3%, di antaranya 47,5% ditumbuhi lebih 1 kuman (polimikroba). Klebsiella speciesdan Staphylococcus aureus merupakan kuman dominan pada ketiga regimen. Kuman Gram negatif lebihbanyak dari Gram positif. Ditemukan satu kasus omfalitis pada cara kering. Lama puput tali pusat lebihcepat pada cara kering.Kesimpulan. Tidak terdapat perbedaan kolonisasi kuman pada ketiga regimen perawatan tali pusat. Kejadianomfalitis ditemukan satu kasus pada cara kering. Lama puput tali pusat lebih cepat pada cara kering.

BACKGROUND: The prevalence of stunted children under 5 years in Riau Province exceeds 27.35% and Kampar District contributed the highest prevalence rate (32.05%) compared to other districts in Riau Province. AIM: This study aims to analyze the parental sociodemographic factors of parents associated with stunting children in Kampar District, Riau Province in Indonesia. METHODS: This type of research is a case-control study on stunted children in Kampar Regency aged under 5 years. Control group was selected by matching process include age, gender, residence, and socioeconomic status. Anthropometric measurements performed and calculated using the World Health Organization Anthro (version 3.2.2, October 2020) include weight-for-age z-score (WAZ), height-for-age z-score (HAZ), weight-for-height z-score (WHZ), and body mass index. The analysis carried out includes univariate and bivariate analysis to find the relationship between the independent variable and the dependent variable. RESULTS: Approximately 139 children aged 2 to 59 months consist of stunted (68) and nonstunted (71) groups. Among the 68 stunted children, 31 (41.3%) were very stunted. The stunted group had decreased in WAZ, HAZ, and WHZ, but only HAZ was statistically significant (p < 0.05). Lower mother’s height and education were determined of parental sociodemographic factors associated with stunting and increased risk of stunted children in Kampar (odds ratio [OR] 3.02 and OR 2.50, 95% confidence interval, respectively). CONCLUSIONS: Lower maternal’s height and education were determine parental sociodemographic factors associated with stunting in Kampar.
