Cigarette Smoking Is the Key Risk Factor of Hip Fracture in Aged Men and Women
In Oct-Dec. 1965, lifestyles of 122,261 men and 142,857 women aged 40 and above residing in 6 prefectures in Japan were studied by the household interview of public health nurses with 95% coverage rate. These subjects were followed up for 17 years from Jan. 1, 1966 to the end of 1982 (see “Life-styles and Mortality”, T. Hirayama, Karger, 1990). One hundred and forty-six cases of hip fracture (44 in men and 102 in women) were recorded in the 55,523 death certificates collected during the follow-up period (m: 31,979; f: 23,544). These cases were tabulated by lifestyles, and risks for hip fracture were calculated according to each risk factor studied at the time of enrollment.
