[A case-control study on risk factors of female hypertension in Tianjin City].

A pair matched case-control study was conducted in 301 pairs female patients with essential hypertension and their controls. The data was analysed by the multiple conditional Logistic regression. The results showed the risk factors associated with hypertension were: body weight (OR = 1.17, 95% CI: 1.12-1.23), the family history of hypertension (OR = 2.18, 95% CI: 1.49-3.21) the family income (OR = 0.73, 95% CI: 0.56-0.94), heart rate (OR = 2.30, 95% CI: 1.41-3.76). OR for the age of menarche was significantly different before and after being adjusted by body weight. There were no relationship between the age of menopause, the age of the first birth, parties, oral contraceptive use or smoking status and hypertension. The paper suggested that the difference of prevalence of hypertension in male and female over 45 years old cannot be explained by menopause or the factors on birth in women.
