Kids who show aggression could have worse health as adults, a study finds.
Lifestyle choices -- what you eat, how much you exercise -- may not be the only forecaster of health later in life. A study in the Canadian Medical Assn. Journal finds that behavior in childhood, such as aggression and social withdrawal, could predict more sickness in adulthood.
The study, released Monday, followed 3,913 children from 1976 to 1978 when they were in grades one, four and seven, through 1992 to 2006. Researchers discovered that displaying aggression in childhood was linked with an 8.1% increase in medical visits, a 44.2% rise in lifestyle-related illnesses and conditions such as obesity, alcohol dependence and type 2 diabetes and a 10.7% increase in injuries. That behavior was also associated with 12.4% more emergency room visits and a 6.2% boost in trips to see specialists.
For girls, childhood aggression was linked with more gynecological visits from ages 18 to 23, although that association wasn't seen when the women were age 29 to 34.
