MILWAUKEE (Reuters) - Conventional wisdom might suggest living in the country would be healthier than the city, but that is not necessarily so, according to a study comparing relative health across cities, suburbs and rural areas. Some of these rural areas are quite depressed, impoverished, with poor social and economic factors, and they have bad health outcomes, Patrick Remington of the University of Wisconsin Population Health Institute said on Thursday. Remington, who expanded the institutes annual statewide study to a national study in 2010, said that some of the least healthy places in Wisconsin were small rural areas. The County Health Rankings takes a snapshot of an areas health using rates of premature death, low birth weight, disease and risk factors such as smoking, obesity, drinking and crime along with education and employment rates. This years study concluded that 48 percent of the healthiest counties were urban or suburban, while 84 percent of the unhealthiest counties were rural.
