Background Premenstrual syndrome (PMS) is a common problem of women of reproductive age, affecting various aspects of their lives. However, limited studies have investigated the effect of internet-based cognitive-behavioral therapy (ICBT) on PMS. Therefore, we aimed to assess whether ICBT can reduce symptom severity of women with PMS and improve their quality of life during the perimenstrual and late follicular phases of menstrual cycle. Methods The study included 92 university students aged 18–35 years who had moderate to severe PMS. The participants were allocated into two groups of 46 using block randomization. The intervention group underwent ICBT for two menstrual cycles, while the control group received no intervention. Before and after the intervention, all participants filled the Daily Record of Severity of Problems (DRSP) for two menstrual cycles and the Quality of Life Enjoyment and Satisfaction Questionnaire—Short Form (Q-LES-Q-SF) on days 1–2 and 11–13 of the menstrual cycle. Data were analyzed using univariate general linear models. Results Four students in the intervention group were lost to follow-up. Following the intervention, the mean score of total PMS symptoms was significantly lower in the intervention group than in the control group (10.4 vs. 20.2, adjusted difference: − 9.9 [95% CI − 13.3 to − 6.6]), and the score of perimenstrual quality of life was significantly higher (64.2 vs. 50.3, 14.1 [8.5 to 19.8]). However, there was no significant intergroup difference in the late follicular quality of life (68.3 vs. 67.3, 1.9 [− 4.4 to 8.1]). Conclusions The ICBT could reduce the symptom severity of women suffering from PMS while improving their perimenstrual quality of life. However, it had no significant effect on the late follicular quality of life. Therefore, this intervention can be used for women with PMS.

Background: The childbirth experience has significant effects on the life of the mother and family. However, there are no Iranian studies which evaluate and measure women's childbirth experiences to provide accurate data on this important matter. The aim of this study is to develop a new guideline to improve women's childbirth experiences by meeting their needs and expectations. Methods/design: The present study will use the mixed method with the explanatory sequential approach. Phase one is a cross-sectional survey with random cluster sampling of the health centers in Tabriz. Eight hundred primiparous women will be selected to measure their childbirth experiences and predictors factors. Phase two is a qualitative study to explore women's perceptions of the aspects and determinants of the childbirth experience. Phase two participants will be selected using purposive sampling from the women who participated in phase one. Phase three involves developing a new guideline to improve women's childbirth experiences. The new guideline will be developed based on the following elements: a) the results of the qualitative and quantitative data from phase one and two, b) a review of the related literature, and c) expert opinions that have been collected using the Delphi technique. Discussion: By exploring women's childbirth experiences and the influencing factors, a culturally sensitive evidence-based guideline can be developed. The provision of the evidence-based guideline resulting from this study might be effective in improving the quality care of the services for pregnant women.

Background The prevalence of gestational diabetes mellitus [GDM] and of its most important predisposing factor, i.e. overweight and obesity, have increased dramatically over the past 20 years. Therefore, the aim of this study was to systematically review the articles on the effect of myo-inositol supplementation on the prevention of GDM in pregnant women with overweight and obesity. Methods We conducted a systematic literature search in electronic database (MEDLINE, Cochrane Library, ClinicalTrials.gov, Embase, ProQuest, PubMed, Google scholar, Scopus, Web of science and forward and backward citations) to identify all randomized controlled trials (RCTs) published until 21 December 2021. Finally, Among the 118 identified records, four studies were eligible and were included in this systematic review. The meta-analysis results were reported in the form of odds ratio (OR) to compare the incidence of GDM and pregnancy outcomes. They were also presented in the form of mean difference (MD) to compare fasting glucose (FG), 1-h and 2-h oral glucose tolerance test (OGTT) levels between the two groups. This study was registered on PROSPERO, number CRD42021290570. Results The results showed that the incidence of GDM was significantly lower in the myo-inositol group (OR 0.32, 95% CI 0.21 to 0.48; P < 0.001; I2 = 0%; Moderate certainty evidence). Moreover, FG-OGTT (MD − 2.64 mg/dl, 95% CI − 4.12 to − 1.17; P < 0.001; I2 = 0%; Moderate certainty evidence), 1-h-OGTT (MD − 7.47 mg/dl, 95% CI − 12.24 to − 2.31; P = 0.005; I2 = 27%; Low certainty evidence) and 2-h-OGTT levels (MD − 10.51 mg/dl, 95% CI − 16.88 to − 4.14; P = 0.001; I2 = 59%; Low certainty evidence) in the myo-inositol group were significantly lower than in the control group. Regarding the pregnancy outcomes, the incidence of gestational hypertension and preterm delivery was significantly lower in the myo-inositol group. However, no between-group difference was observed in the other outcomes. Conclusions Based on the results, myo-inositol has shown to be a new and safe preventive strategy in reducing the incidence of GDM and in regulating FG and 1-h and 2-h OGTT levels, and also in reducing the incidence of GDM complications such as preterm delivery and gestational hypertension in pregnant women with overweight and obesity.

Sleep disorder is very common during pregnancy. Non-pharmacological treatments are a priority to improve the sleep pattern. This study aimed to determine the effect of cognitive–behavioral counseling with or without Citrus aurantium essential oil on sleep quality (primary outcome) and anxiety and quality of life (secondary outcomes). This randomized controlled trial was performed on 75 pregnant women in Tabriz, Iran. Participants were randomly assigned to the intervention and control groups. The first intervention group received 8 sessions of cognitive–behavioral counseling and aromatherapy with Citrus aurantium essential oil 15–20 min before bedtime. The second intervention group received cognitive–behavioral counseling and aromatherapy with placebo and the control group received only routine prenatal care. Pittsburgh Sleep Quality Index, Pregnancy-Specific Quality of life Questionnaire, and Pregnancy-Specific Anxiety Scale were completed before and after intervention. After the intervention based on ANCOVA test and by adjusting the baseline score, the mean score of anxiety in the intervention group 1 (AMD: − 4.54; 95% CI − 6.79 to − 2.28) and intervention group 2 (AMD: − 3.30; 95% CI − 5.60 to − 0.97) was significantly lower than the control group. Also, the mean score of quality of life in intervention group 1 (AMD: 2.55; 95% CI 0.45–4.65) and intervention group 2 (AMD: 2.72; 95% CI 0.60–4.83) was significantly higher than the control group, but there was no statistically significant difference between the study groups in terms of sleep quality ( P > 0.05). Also, there was no statistically significant difference between the two intervention groups after the intervention in terms of anxiety ( P = 0.379) and quality of life ( P = 0.996). Cognitive–behavioral counseling reduced anxiety and improved quality of life. However, further trials are required to reach a definitive conclusion.
