Purpose: This study examined whether maternal characteristics and pregnancy complications associated with low birth weight influence the growth of infants aged 1–6 months in the Kaliwungu Health Center working area, Kudus Regency. The study hypothesized that selected maternal and pregnancy-related determinants would be associated with infant growth outcomes. Research Method: A quantitative observational study with a retrospective cohort approach was conducted among 38 infants aged 1–6 months with a history of low birth weight. Total sampling was applied. Data were obtained from medical records and observation sheets covering maternal age, education, occupation, parity, gestational age, anemia, chronic energy deficiency, preeclampsia, anxiety, and infant growth based on body weight. Data were analyzed using univariate statistics and Fisher’s Exact Test. Results and Discussion: Most infants showed normal growth (76.3%), while 23.7% were classified as malnourished. No significant association was found between infant growth and maternal age (p=0.312), education (p=1.000), occupation (p=0.242), parity (p=0.436), gestational age (p=0.126), anemia (p=1.000), chronic energy deficiency (p=1.000), preeclampsia (p=0.613), or anxiety (p=1.000). Although growth variation was observed, many low birth weight infants demonstrated adequate early growth. Implications: These findings emphasize the need for continuous pregnancy prevention strategies, early risk detection, and routine growth monitoring for low birth weight infants. Further studies with larger samples are needed to identify longer-term determinants of postnatal growth.
