The purpose of the present study was to examine the relationship between severe pre-eclampsia/eclampsia (toxaemia) and obesity. We collected sociodemographic, anthropometric, medical and pregnancy outcome data from the hospital records of 248 Israeli women diagnosed with either pregnancy-induced or chronic hypertension, and compared these data to a control group of 236 women. Univariate analysis showed that while there exists a statistically significant positive association between obesity and hypertension (both pregnancy-induced and chronic) obesity presents no added risk to the development of toxaemia. Furthermore, we found a significant decrease in the rate of obesity among primigravid versus multigravid mothers with toxaemia superimposed on pregnancy-induced hypertension. On the other hand, primigravid mothers with PIH were at an increased risk of developing toxaemia as compared to multigravid women. These results suggest that obesity is not a significant factor in the development of toxaemia.
