Background: Measurement of mean arterial blood pressure is better predictive factor for pregnancy-induced hypertension than measurement of the systolic and diastolic blood pressure or systolic blood pressure. According to the theory of “protective effect of fish oil supplementation on pregnancy-induced hypertension “and the importance of blood pressure control in pregnancy, the present study was conducted to investigate the effect of fish oil supplementation in pregnancy on mean arterial blood pressure. Materials and Methods: In this clinical trial study, 120 healthy pregnant women were randomly divided into two groups of 60 persons. Same prenatal care was performed for both groups and the intervention group was received Salmon fish oil capsule 1000 mg/day, from 16th week to the end of the pregnancy. Systolic and diastolic blood pressure were measured in both groups once every four weeks up to 28th week, every 2 weeks from 28th till 36th week and once every week up to the end of pregnancy. Mean arterial blood pressure was calculated and all gathering data was analyzed with T test and Mann-Whitney test. Results: Mean arterial blood pressure in the intervention and control group was 80.76±5.50 and 78.46±4.50 mmHg which was not significantly different (p>0.05). Conclusion: The results showed that adding fish oil supplements to the diet of pregnant mothers had no significant effect on mean arterial blood pressure.

Introduction: Sexual self-efficacy is a fundamental concept in behavior, health, and sexual performance that changes over time due to events such as pregnancy and childbirth. The present study was conducted to investigate factors affecting sexual self-efficacy in pregnant women in Arak City.
Methods: The current research is a cross-sectional, descriptive, and analytical study conducted with 234 pregnant women aged 18 to 40 who had minimal reading and writing literacy and lived with their husbands. Ten comprehensive urban health centers were selected using cluster sampling. Data were collected through a demographic information checklist and a sexual self-efficacy questionnaire. Data analysis was done using Mann-Whitney U and Kruskal-Wallis and (LSD) tests.
Results: The mean score of sexual self-efficacy of pregnant women was 28.51 ± 6.45 and was at a high level. Kruskal-Wallis test showed that the sexual self-efficacy of pregnant women is unrelated to their education (P = 0.2). There is a significant relationship between education and the education of their spouses (P = 0.04). (LSD) test showed a significant difference between different levels of education of husbands and the sexual self-efficacy of pregnant women. Also, no significant relationship was observed between the mean score of sexual self-efficacy and other variables.
Conclusions: The sexual self-efficacy of pregnant women is related to the education of their husbands, so it is suggested to provide a suitable platform for increasing the knowledge and awareness of men.
