Did your study address woman with chronic illness who breastfeed, and had previous weight gain due to medication prior to giving birth ? If so what were their statistics for developing type 2 or metabolic syndrome?
I breastfed my daughter for six months I was nursing her every hour and a half during the day and every two hours through out the night. Because I have fibromyalgia and CFIDS I had stopped all medications through out my pregnancy and of course while I was breast-feeding. The one morning I nursed her from both breast breasts and twenty minutes later she was screaming as if she had not been fed in hours was when I decided it was time for formula. I hoped six months of solid breast-feeding would give her all the benefits she could possibly receive from a very unpleasant experience. I would have quit but I knew it was the best possible thing I could do for my baby. She is now 17 years old a Jr in high school with a 4.33 GPA so she defiantly has the increase in brain function benefit. However, she had horrible colic for the first six months of her life, and now has IBS with constipation. She has allergies to the environment and she is on her second round of five years worth of weekly allergies shots, and she has migraines.
As for me I did not lose one bit of body fat while nursing, and fifteen years after breastfeeding I have become prediabetic. Now all of my weight gain is due to the medications I take to control my fibromyalgia many of these drugs are taken by other people with Type 2 diabetes, depression, and other health related problems.. Losing weight and trying to stay healthy with a chronic disease is not easy and it was extremely hard to fight through all the physical problems I was experiencing so I could breast feed my daughter but I knew if I could give her any extra benefit to her health by doing so it was worth it.

Doing the math, that means, my mother should have reduced the risk of her developing type 2 diabetes by 120% for the first year and knowing that she breastfed all my other 5 siblings and myself for exactly 2 years, this would be a reduction in this risk by at least 240% esp that she is not obese!!, I'm not calculating the duration this protection covers because the onset of her diabetes was when my youngest sis was 3 years old and I was 14 which of course is different from what the study reveals. If it discloses the situations that led the 120 participants to develop precursory type 2 Diabetes conditions that would be more interesting..

Now, I am into clinical research myself, and my interest in making sure she is well taken care of is driven by my willingness to look for all that can have relevance including a study like this, thanks for sharing this diabeteshealth...
