Objective: The objective of the study was to examine the relationship between breastfeeding patterns, markers of maternal human immunodeficiency virus (HIV) disease, and woman's breast pathology.
Study design: Secondary data analysis from a randomized breastfeeding trial including 947 HIV-infected women (n = 5982 visits) from breastfeeding initiation until 6 months postpartum; 1 month after breastfeeding cessation; or loss to follow-up or death. Generalized estimating equations assessed the effects of breastfeeding pattern and maternal HIV status on breast pathology.
Results: One hundred ninety women (20.1%) had a breast problem; 86 (9.1%) had mastitis; and 31 (3.3%) had abscess. After confounder adjustment, nonexclusively breastfeeding women had an increased risk of breast problems (odds ratio, 1.98; 95% confidence interval, 1.33-2.95) and mastitis (odds ratio, 2.87, 95% confidence interval, 1.69-4.88) compared with exclusive breastfeeders. Women with a CD4 count less than 200 cells/μL tended to have an increased risk of abscess.
Conclusion: Nonexclusive breastfeeding significantly increased the risk of breast pathology. Exclusive breastfeeding is not only optimal for infant health but it also benefits mothers by reducing breast problems.
