Perbandingan Pertumbuhan Bayi Usia 0-12 Bulan yang Diberikan ASI dan Susu Formula Di Wilayah Kerja Puskesmas Kampung Harapan

Abstract

Background: Exclusive breastfeeding is highly recommended for infants during the first six months of life. Formula feeding may serve as an alternative when breast milk production is insufficient to meet the infant’s nutritional needs. Objective: The objective of this study was to determine differences in infant growth between those who were given breast milk and those who were given formula milk. Method: This study used a quantitative design with a cross-sectional approach. The study population consisted of 210 live infants aged 0–12 months, based on Posyandu visit records within the working area of Kampung Harapan Health Center. The research sample, collected from February to March 2025, comprised 75 infants selected using purposive sampling. Results: The findings showed that among infants who were breastfed, 25 respondents (86.2%) had normal growth in terms of body weight and length, while 4 respondents (13.8%) did not. In contrast, among infants who were formula-fed, 10 respondents (62.5%) had normal growth and 6 respondents (37.5%) did not. Conclusion: It can be concluded that in this study, most infants who were exclusively breastfed exhibited normal growth according to their age.
