基于女性特征血压分布的相关性分析

Abstract

针对辽宁阜新地区农村人群的高血压流行病学调查数据，以多维标度法(MDS)方法体系中基于χ2统计量的关联性度量方法为主，辅以Somers和Kendall关联性度量方法，分析和探讨女性特征对血压分布的影响。重点分析了40~54岁的女性绝经与否和生育胎数两个因素对血压的影响。数据分析表明，绝经与否对收缩压影响显著地大于对舒张压的影响，在血压等级迁移的敏感性方面，已绝经女性从正常高值向轻度和中度高血压迁移的机会大于未绝经女性，且在由正常高值向轻度高血压迁移上收缩压更敏感。对生育胎数因素，分析表明，生育第3胎对血压存在特异性影响，生育3胎的女性收缩压由中度迁移为重度、舒张压下由轻度迁移为中度级别的风险大。在绝经与否和生育胎数两个因素的交互影响上，生育胎数在收缩压上的影响应重点关注在绝经之前，而绝经特征对生育胎数在收缩压上的影响较为一致，而对舒张压的影响却极为复杂。 According to the data of epidemiological survey on hypertension in rural population of Fuxin, Liaoning province, the method of correlation measurement based on χ2 statistic in the MDS method system are mainly used, and supported by Somers and Kendall correlation to analyze and discuss the effects of female characteristics on blood pressure distribution. This paper mainly analyzes the effects of two factors of menopause for women aged 40-54 and the number of births on blood pressure. For the factor of menopause, the data analysis shows that menopause has greater effects on systolic blood pressure than diastolic blood pressure. In the sensitivity of blood pressure level migration, the chance is greater for post-menopausal women migrating from high normal to mild and moderate blood pressure than non-menopausal women, and systolic blood pressure is more sensitive migrating from high normal to mild blood pressure. For the factor of the number of births, the data analysis shows being equal to 3 has special effects on blood pressure. For women who have 3 children have higher risk on systolic blood pressure migrating from moderate to severity, diastolic blood pressure migrating from mild to moderate. In the interactive effects between menopause or not and the number of births, the effects the number of births has on diastolic blood pressure should focus on pre-menopause. The effect menopause has on the number of births is consistent on systolic blood pressure, while is complicated on diastolic blood pressure.
