(Newser) – New research has linked low birth weight and slow growth in childhood to increased levels of hostility in adults, Reuters reports. Researchers also discovered that the higher levels of aggression were linked to health trouble, including coronary problems, type 2 diabetes and earlier death. The levels of hostility appeared unconnected to any other factors like gender, number of siblings or educational level.

"We interpret our findings as suggesting that hostility and cardiovascular disease may share a common vulnerability factor in fetal and early postnatal life," wrote the authors of the study, published in the journal Psychosomatic Medicine.
