Iracema Leroi, MD, honorary lecturer, department of psychiatry, University of Manchester, Manchester, United Kingdom, presented the findings of a large cohort case-control study here on May 3rd at the American Psychiatric Association Annual Meeting. "This is the first time anyone has looked at overall psychological distress in relationship to breastfeeding over the long-term," she said. The new analysis used data from the 1970 British Cohort Study, which recorded 17,000 births in the United Kingdom over a 1-week period in 1970. For the first 3 months, mothers were asked about whether the infant was breastfed and how long breastfeeding lasted. In 2000, all of nearly 8,500 now-adult subjects still enrolled in the study were administered the 24-question Malaise Inventory, which asked about their levels of stress, anxiety, and other psychological illnesses. Those subjects -- especially males -- who were breastfed for at least 1 month scored significantly better on the test than those who had been breastfed for up to 1 month, Dr. Leroi reported. This was significant at the P =.013 level, she added. While it is not known how breastfeeding might boost psychological well-being, Dr. Leroi noted that "breastfeeding confers many benefits on infant health, such as increased size and growth, and it is possible that some of these may impact on later psychological well-being." The positive impacts of breastfeeding on bonding and cognitive development also probably play major roles in reducing stress later in life, she added. Other factors were shown to play a role in reducing long-term psychological distress, she said. Among them the mother having smoked during pregnancy (P =.001), the child being separated from the mother for more than 1 month before the age of 5 years (P =.009), and low birth-weight (P =.01).
