Therefore, this study aimed to determine the time to adequate weight gain and its predictors among low-birth-weight preterm neonates admitted to neonatal intensive care unit of public hospitals in Bahir Dar City. An institution-based retrospective follow-up study was conducted from March 4 to April 3, 2023, using three years of data. About 344 low-birth-weight preterm babies were recruited and followed up until 28\u00a0days of age. Model goodness-of-fit was checked by Cox Snell residuals test. The Cox-Proportional Hazards Model was used to assess predictors of weight gain with a statistically significant level of <jats:italic>P<\/jats:italic>-value\u2009&lt;\u20090.05. The median weight gain time was 15\u00a0days with an overall incidence density rate of 6.3 per 100 person-day of observation (95% CI 0.055, 0.071). Absence of medical problems of mothers (AHR: 1.63, 95% CI 1.015, 4.614), spontaneous vaginal mode of delivery (AHR: 1.53, 95% CI 1.028, 2.593), and long duration of labor (AHR: 3.18, 95% CI 1.579, 6.413) were significant predictors. The time of adequate weight gain was long. Early detection and management of significant predictors is recommended.<\/jats:p>","DOI":"10.1038\/s41598-024-66856-7","type":"journal-article","created":{"date-parts":[[2024,7,26]],"date-time":"2024-07-26T18:04:11Z","timestamp":1722017051000},"update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Time to adequate weight gain and predictors among low-birth-weight preterm neonates at Neonatal Intensive Care Unit of hospitals in Bahir-Dar"],"prefix":"10.1038","volume":"14","author":[{"given":"Dagnew","family":"Tigabu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hailemariam","family":"Gezie","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fekadie Dagnew","family":"Baye","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shiferaw","family":"Birhanu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hailemariam Mekonnen","family":"Workie","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2024,7,25]]},"reference":[{"issue":"12","key":"66856_CR1","first-page":"10","volume":"14","author":"V Khandre","year":"2022","unstructured":"Khandre, V., Potdar, J. & Keerti, A.
