Original ArticleThe Long-Term Effects of Breastfeeding on Child and Adolescent Mental Health: A Pregnancy Cohort Study Followed for 14 Years
Section snippets
Methods
From 1989 to 1992, 2900 women were enrolled in the Western Australian Pregnancy Cohort (Raine) Study through the public antenatal clinic at the major obstetric hospital in Perth, Western Australia, and nearby private practices. The criteria for enrollment were gestational age between 16 and 20 weeks, sufficient proficiency in English to understand the implications of participation, an expectation to deliver at the hospital, and an intention to remain in Western Australia for long-term follow-up.
Results
There were missing cases at each follow-up because of the longitudinal nature of the data collection, and these were excluded from analysis. Of the 2366 participants with available data, 11% were never breastfed, 19% were breastfed for less than 3 months, 19% were breastfed for between 3 and up to 6 months, 28% were breastfed between 6 and up to 12 months, and 24% were breastfed for 12 months or more. The children who were breastfed for 6 months or longer had significantly lower mean CBCL
Discussion
We have shown that a shorter duration of breastfeeding was associated with increased mental health morbidity throughout a period spanning early childhood to adolescence. This association was evident for the continuous measures of total, externalizing, and internalizing behaviors, as well as for dichotomous measures of morbidity, which reflect clinically significant behavioral problems. Furthermore, these associations persisted after adjustment for family, social, economic, birth, and

Across numerous studies, breastfeeding has been associated with functions such as social-emotional processing (Oddy et al., 2010), motor performance (Belfort et al., 2016; Michels et al., 2017), cognition and memory (Belfort et al., 2016), as well as language (Dee et al., 2006). Recent work showed that exclusively breastfed girls, compared to girls not exclusively breastfed, scored higher on cognitive assessments during infancy and the preschool years (6–60 months), while no differences were observed in boys at this age (Guzzardi et al., 2020).
