The main objective of this study is to determine factors that associated with pregnancy induced hypertension at Ramathibodi Hospital 1992. Statistical study between logistic regression analysis & discriminant analysis. The study design was case control study that selected cases by simple random sampling. Sample of two groups are 250 for cases group and 375 for group respectively. The logistic regression analysis of 15 variables, shown that mean arterial blood pressure at second trimester (OR =177.97), protien uria ( OR = 26.10 ), parity ( OR = 21.38), marital status ( OR = 9.32) weight gain (OR = 7.17) and age (OR = 3.21) are related with pregnancy induced hypertension. Model has percent of variance explained 80.27 and percent of predicted classification 94.70. Another analysis with out mean arterial pressure, It was found that protienuria (OR = 65.11) pariety ( OR = 19.35 ), diabetic mallitus ( OR = 16.08 ), weight gain (OR = 10.89) marital status (OR = 8.85), hematocrit (OR = 3.15) and age ( OR = 2.94) associated with pregnancy induced hypertension. Model has percent of variance explained 69.01 and percent of predicted classification 94.70 . With the discriminant analysis, the mean arterial blood pressure ( structure coefficients = 0.7452 ), weight gain ( structure coefficients =0.4454), marital status (structure coefficients =0.4354) , protienuria ( structure coefficients = 0.4326) and parity (structure coefficients = -.3984) could discriminated cases group and controls group. Discriminant model had percent of explained variance 69.67 and had percent of predicted classification 94.70. The analysis without mean arterial blood pressure, found that weight gain ( structure coefficients=0.5422), marital status (structure coefficients = 0.5299), protienuria ( structure coefficients = 0.5265 ) and parity ( structure coefficients = -.4848 ) could discriminated sample cases and sample controls. When compared between the two methods analysis, it was found that logistic regression analysis had more factors that associated with pregnancy induced hypertension than discriminant analysis. Factors that were different was age. The logistic model had more percent of explained variance and percent of classification than discriminant method. When nalized without mean arterial blood pressure, it was found that the logistic model had diabetic mallitus, hematocrit and age while discriminant model didnt effect, percent of explained variance and percent of predicted classification had more.
