This article examines the association of family history of heart disease and leisure-time physical activity with incident heart disease.
The data are from the 1994/95, 1996/97 and 1998/99 longitudinal household components of Statistics Canada's National Population Health Survey. This study is based on information provided by 9,255 respondents aged 20 or older who reported that, in 1994/95, they were free of diagnosed heart disease and in good health.
Multiple logistic regression was used to estimate the association of family history and physical activity with a new diagnosis of heart disease, while controlling for age, sex, educational attainment, smoking, high blood pressure, diabetes, and body mass index.
When family history and other risk factors were taken into account, people who, in 1994/95, engaged in regular physical activity at a moderate level or beyond had lower odds of receiving a new diagnosis of heart disease than did sedentary individuals. People with a family history of heart disease who regularly participated in at least moderate physical activity had lower odds of developing heart disease than did their sedentary counterparts.
本文研究心脏病家族史和休闲时间身体活动与心脏病发病之间的关联。
数据来自加拿大统计局全国人口健康调查1994/95、1996/97和1998/99年的纵向家庭部分。本研究基于9255名20岁及以上受访者提供的信息，这些受访者报告在1994/95年时未被诊断出患有心脏病且身体健康。
采用多因素logistic回归来估计家族史和身体活动与心脏病新诊断之间的关联，同时控制年龄、性别、教育程度、吸烟、高血压、糖尿病和体重指数。
在考虑家族史和其他风险因素时，1994/95年进行中等强度或更高强度规律身体活动的人，与久坐不动的人相比，新诊断出心脏病的几率更低。有心脏病家族史且经常至少参加中等强度身体活动的人，与久坐不动的同龄人相比，患心脏病的几率更低。
