The February edition of the Journal of Nutrition offers new insights into possible associations between infant feeding and health outcomes related to obesity. According to David Barker, M.D., Ph.D., professor of clinical epidemiology at the University of Southampton, UK and professor of Cardiovascular in the Department of Medicine at the Oregon Health and Science University and one of the authors of the report, "A longer period of breastfeeding was associated with lower BMI (a measure for weight) at one year of age. This relationship disappeared by the age of 7 years." Similarly, there was no significant difference in BMI at the age of 60 years associated with duration of breastfeeding.
