Objective:To explore the related risk factors of hypertensive disorders in pregnancy in Tibet Lhasa area, and provide reference for prevention and treatment of hypertensive disorders in pregnancy. Methods:One hundred and thirty four pregnant women with hypertensive disorder were admitted by Tibet Military Region General Hospital from January 2010 to December 2015 were chosen as the case group, and the 134 healthy patients in the same time were chosen as the control group. The risk factors were studied, including age, educational level, aboriginal or immigrant, living altitudes, calcium addition and history of hypertension. Results:Hypertensive disorders in pregnancy was related to age, educational level, living altitudes, calcium addition and history of hypertension (P<0.05). Multivariate Logistic regression analysis showed that age (OR=0.598,P=0.044), educational levelOR=0.187, P=0.035), living altitudes ≥ 4 000 mitres (OR=2.361, P=0.023), without regular supplementation of calcium (OR=2.526, P=0.048), and history of hypertension before pregnancy (OR=67.231, P=0.001), living period (OR=2.394, P=0.029) and ethnic distribution (OR=2.481, P=0.036) were risk factors for hypeaension in pregnancy. Contribution from large to small:history of hypertension before pregnancy, living altitudes, educational level, ethnic distribution, age and supplementation of calcium. Conclusion:Old age, low educational level, high living altitudes, not having regular calcium supplementation, history of hypertension before pregnancy, living period and ethnic distribution were risk factors for hypeaension in pregnancy in Tibet Lhasa area. It is impartment to control the risk factors among targeted patients and prevent the hypertension in pregnancy. |
