摘要:

Background and PurposeThe aim of this study was to relate risk factors in middle-aged men and women to stroke mortality over a long follow-up period.MethodsIn the early to mid 1970s, 7052 men and 8354 women from the Renfrew/Paisley prospective cohort study in Scotland were screened when aged 45 to 64 years. Risk factors measured included blood pressure, blood cholesterol and glucose, respiratory function, cardiothoracic ratio, smoking habit, height, body mass index, age, preexisting coronary heart disease, and diabetes. These were related to stroke mortality over 20 years of follow-up.ResultsWomen's stroke mortality rates were similar to men's, unlike coronary heart disease mortality, in which case women's rates were lower than men's. Diastolic and systolic blood pressure, smoking, cardiothoracic ratio, preexisting coronary heart disease, and diabetes were positively related to stroke mortality for men and women, while adjusted forced expiratory volume in 1 second and height were negatively related. Cholesterol and body mass index were not related to stroke mortality. Glucose in nondiabetics was positively related to stroke mortality for women but not men, and there was evidence of a threshold effect at the highest levels of glucose. Former smokers had mortality rates that were similar to those of never-smokers. In sex-specific multivariate models, most variables retained a statistically significant association with stroke mortality, illustrating the multifactorial etiology of stroke.ConclusionsOverall, findings for women were similar to those for men. Control of risk factors for reduction of stroke mortality should be targeted at men and women in a similar fashion, particularly with reference to smoking cessation and blood pressure control.
