Background Traumatic birth experience has undesirable effects on the life of the mother, child, family, and society. The identification of predictive factors can be useful in improving birth experiences among women. This study aimed to assess the prevalence of a traumatic birth experience and identify its predictors among a group primiparous women. Methods A cross-sectional study was conducted among 64 health centres in Tabriz, the second largest city in Iran. Cluster sampling was used to recruit 800 eligible women at one to 4 months postpartum. The Persian version of the Childbirth Experience Questionnaire was used to measure the womens’ birth experiences. Data were collected through face to face interviews and analysed mainly by multivariable logistic regression. Results The prevalence of traumatic birth experience was 37% in the study group. The independent predictors of the traumatic birth experience were related to antenatal and intrapartum factors. The antenatal predictor was the lack of exercise during pregnancy (OR = 2.81, CI 1.40–5.63, P = .003) and the intrapartum predictors were the absence of pain relief during labour and birth (OR = 4.24, CI 2.12–8.50, P < .001), and the fear of childbirth (OR = 3.47, CI 1.68–7.19, P < .001). Conclusions The findings revealed the high rate of traumatic birth experience among the primimarous women and identified the importance of a woman-centered care where a woman can actively make decision about the care she receives receive during labour and birth.

BackgroundProbiotics can alter the colonic microbiota and might improve bowel function.ObjectivesThe aim of this study was to evaluate the effect of the consumption of yogurt, enriched with Bifidobacterium and Lactobacillus 4.8 × 1010 (CFU) on the symptoms of constipated pregnant women.Materials and MethodsThis triple-blind randomized controlled trial was conducted on 60 constipated pregnant women who were diagnosed by the ROME III criteria in Tabriz, Iran from December 2014 to July 2015. Participants were randomly put into two groups including the treatment and the control group through block randomization. The treatment group received 300 g of yogurt enriched with Bifidobacterium and Lactobacillus 4.8 × 1010 colony forming units (CFU) (n = 30) while the control group received conventional yogurt (n = 30) for 4 weeks. The defecation frequency, stool consistency, straining during defecation, sensation of anorectal obstruction, sensation of incomplete evacuation and manual manoeuvres to facilitate defecation were primary outcomes while the amount of defecation, stool colure, and quality of life were secondary outcomes.ResultsThe frequency of defecation was increased from 2.1 (0.8) at baseline to 8.3 (4.4) in the probiotic yogurt group vs. 2.3 (0.7) at baseline to 8.1 (4.3) in the conventional yogurt group at the end of 4th week. These results were based on the repeated measure ANOVA test and there was no statistically significant difference between the two groups (mean difference: 0.1; Confidence Interval 95%: -1.4 to 1.7; P = 0.872). Constipation symptoms including straining, anorectal obstruction, manipulation to facilitate defecation, consistency of stool and color of stool were improved significantly (P < 0.05) in both groups. In addition, the amount of defecation was significantly increased in both groups (P < 0.05), while incomplete evacuation was significantly reduced in the treatment group (P = 0.01). There was no statistically significant difference between the groups in the mean scores of physical (P = 0.726) and mental (P = 0.678) aspects of quality of life after the intervention with the adjusting of baseline scores.ConclusionsConsumption of 300 g/day probiotic and conventional yogurt can play a role in improving the symptoms of constipation during pregnancy.

BackgroundAssessing women’s childbirth experiences is a crucial indicator in maternity services because negative childbirth experiences are associated with maternal mortalities and morbidities. Due to the high caesarean birth rate in Iran, measuring childbirth experience is a top priority, however, there is no standard tool to measure this key indicator in Iran. The aim of present study is to adapt the “Childbirth Experience Questionnaire 2.0” to the Iranian context and determine its psychometric characteristics.MethodsChildbirth Experience Questionnaire 2.0 was translated into Farsi. A total of 500 primiparous women, at 4 to 16 weeks postpartum, were randomly selected from 54 healthcare centres in Tabriz. Internal consistency and reliability was calculated using the Cronbach’s Coefficient alpha and Intraclass Correlation Coefficient, respectively. Construct validity was assessed using exploratory and confirmatory factor analysis and discriminant validity using the known-group method and the Mann-Whitney U-test.ResultsThe internal consistency and reliability for the total tool were high (Cronbach’s alpha = 0.93; Intraclass Correlation Coefficient = 0.97). Explanatory factor analysis demonstrated the adequacy of the sampling (Kaiser-Meyer-Olkin = 0.923) and significant factorable sphericity (p < 0.001). Confirmation factor analysis demonstrated acceptable values of fitness (RMSEA = 0.07, SRMSEA = 0.06, TLI = 0.97, CFI > 0.91, x 2/ df = 4.23). Discriminatory validity of the tool was confirmed where the CEQ score and its subdomains were significantly higher in women who reported having control over their childbirth than women who did not.ConclusionThe Farsi version of the Childbirth Experience Questionnaire 2.0 tool is a valid and reliable tool and can be used to measure the childbirth experience in Iranian women.

BackgroundPregnancy is considered a stressful event, results in higher levels of oxidative stress and considerable changes in physiological and metabolic functions such as gestational diabetes mellitus (GDM). Due to the cumulative effect of antioxidants and considering the controversies in this area, this study was undertaken to investigate the total antioxidant capacity (TAC) of saliva in pregnant women whit gestational diabetes in comparison to non-diabetic pregnant women.Material and MethodsIn this cross-sectional study (2015-16), a total of 31 women with a diagnosis of GDM and 59 non-diabetic pregnant women were included in the diabetic and control groups, respectively. Salivary samples were collected by spitting method. When all samples were collected, total antioxidant capacity (TAC) was measured with the use of a commercial kit following the manufacturer’s instructions. Data were analyzed with descriptive statistics and Mann-Whitney test using SPSS 18.ResultsAverage TAC level in the saliva of women with gestational diabetes was 0.10 ± 0.14, with 0.04 ± 0.11 in non-diabetic pregnant women. Nonparametric Mann-Whitney test showed that this difference was statistically significant (P=0.024).ConclusionsUnder the limitations of the present study it can be concluded that there is an increase in oxidative stresses during pregnancy, followed by an increase in the total levels of salivary antioxidants to counteract such stresses. Therefore, it is expected that determining the salivary antioxidant levels during pregnancy can be an alternative technique for the early diagnosis of diabetes. Key words:Gestational diabetes mellitus, pregnancy, saliva, total antioxidant capacity.
