摘要
Objective While several studies have shown that milk formula feeding is associated with faster infant weight gain compared with exclusively breast feeding (EBF), we explored the possible reverse association that infant weight gain influences the duration of EBF. Design Prospective birth cohort study (Cambridge Baby Growth Breastfeeding Study) born 2015-2018. Setting Cambridge, UK. Participants Full-term, singleton, normal birthweight infants who received EBF for 2-5 completed weeks (n=54), 6-11 weeks (n=14) or 12 or more weeks (n=80). Intervention Weight gain from birth to 2 and 6 weeks. Main outcome and measure Duration of EBF. Results Faster infant weight gain during EBF predicted longer duration of EBF. Among all 148 infants, each +1 unit gain in weight SD score (SDS) between birth and 2 weeks (while all infants received EBF) reduced the likelihood of stopping EBF between 2 and 5 weeks by similar to 70% (OR 0.32; 95% CI 0.12 to 0.77; adjusted for sex, gestational age at birth, birth weight and mother's age, prepregnancy BMI and education). Similarly, among infants EBF for 6 or more weeks (n=94), each +1 unit gain in weight SDS between birth and 6 weeks reduced the likelihood of stopping EBF between 6 and 11 weeks by similar to 80% (OR 0.18; 95% CI 0.05 to 0.63). Conclusions Slower early infant weight gain was consistently associated with subsequent earlier discontinuation of EBF.We conjecture that broader recognition of the wide range of normal infant growth might encourage parents to not stop EBF earlier than they intended.
