title: Determinants of Pre-eclampsia: A Case-control Study in a District Hospital in South India.
abstract: OBJECTIVE
  The objective was to study the determinants of pre-eclampsia among pregnant women admitted for delivery in a district hospital.
  
  
  METHODS
  A case-control study was conducted at District Lady Goschen Hospital, Dakshina Kannada district, Karnataka, South India. The group of pregnant women with pre-eclampsia comprised those with hypertension after the 20th week of gestation with associated proteinuria, and controls were pregnant women not diagnosed with pre-eclampsia. A total of 100 cases and 100 controls were selected for the year 2006. Study variables included mother's age, parity, body mass index, history of chronic hypertension, history of diabetes, history of renal disease, family history of hypertension, and history of pre-eclampsia in earlier pregnancy.
  
  
  METHODS
  Chi-square test, and crude and adjusted odds ratio with 95% confidence intervals were used for statistical analysis.
  
  
  RESULTS
  Significant risk factors identified in univariate analysis included prepregnancy body mass index (BMI > 25) (OR = 11.27), history of chronic hypertension (OR = 8.65), history of diabetes (OR = 11.0), history of renal disease (OR = 7.98), family history of hypertension (OR = 5.4), history of pre-eclampsia in earlier pregnancy (OR = 9.63), and multiple pregnancy (OR = 4.85). Multiple logistic regression analysis revealed that the prepregnancy BMI of >25 (OR = 7.56), history of chronic hypertension (OR = 6.69), history of diabetes (OR = 8.66), history of renal disease (OR = 5.6), family history of hypertension (OR = 5.48), and multiple pregnancy (OR = 5.73) are the significant risk factors of pre-eclampsia.
  
  
  CONCLUSIONS
  Pregnant women at risk of pre-eclampsia should be identified and high-quality antenatal care should be given in order to minimize the complications of pre-eclampsia both for the mother and the fetus.
