Abstract

Background: Pregnancy-induced hypertension (PIH) is a pregnancy-specific condition that occurs after the 20th week of gestation. These physiologic changes can be aggravated by undernutrition. There are some evidence based on the importance of nutrient deficiency in developing this syndrome. Therefore, the aim of present study was to determine the nutritional risk factors for pregnancy induced hypertension in a group of pregnant women in Isfahan. Methods: In this case-control study, we recruited 46 Isfahanian pregnant women in two groups (with and without PIH). They were 19 to 45 year-old and they did not consume any antihypertensive or diuretic medications. Demographic questionnaire and food frequency questionnaire were filled in both groups. Results: There were no significant differences in energy and vitamin E and C intakes between the two groups. Zinc and calcium intakes were lower in women with PIH compared to those without PIH (P = 0.04 and P = 0.007, respectively). Riboflavin and protein intakes were lower in women with PIH compared to subjects without PIH (P = 0.03 and P = 0.01, respectively). Conclusions: Lower intake of calcium, zinc, riboflavin and protein should be considered as possible risk factors for PIH. Adequate intake of dairy products which are good sources of mentioned nutrients are recommended to prevent PIH.
