Logistic regression analysis of risk factors associated with retinopathy in pregnancy-induced hypertension patients

Objective To understand the risk factors associated with retinopathy in pregnancy-induced hypertension syndrome(PHS) patients. Methods 97 PHS pregnants were examine and the data concerning the age,number of pregnancy,trimester of pregnancy,body weight,edema at lower extremities,urinary protein,systolic pressure,diastolic pressure,hemoglobin,hematocrit,blood group and retina were collected.Simple logistic regression analysis was made for analysis of all the risk factors and then those of statistically significant variables were chosen for multiple logistic regression analysis. Results The results of multiple logistic regression analysis showed that the statistically significant risk factors were diastolic pressure(OR=2.904),urinary protein(OR=2.481) and the number of pregnancy(OR=1.647). Conclusion Control of diastolic pressure,unrinary protein and number of pregnancy is effective for reducing the risk of retinopathy.
