Background Self-rated health in pregnancy can be a predictor of adverse childbirth outcomes and maternal health problems. The aim of the present study was to investigate the effect of maternal self-rated health on the type of delivery in Bandar Abbas pregnancy cohort.Methods This study used data of 247 mothers registered in a prospective cohort study on pregnant women in the suburbs of Bandar Abbas city, South of Iran. Self-rated health of mothers in pregnancy was measured by the answer to the question: “How do you evaluate your health in general?” The study outcome defined as having cesarean section measured at the second visit during postpartum period. The relative risk (RR) and 95% confidence interval (CI) was calculated using Cox regression models.Results The prevalence of bad/poor, good/excellent Self-rated health and cesarean section was 19.3% (n=42), 80.97% (n=200) and 40%, respectively. Compared to good self-rated health, the risk of cesarean section was 78% higher (RR= 1.78, 95% CI 1.32-2.4) in mothers with bad self-rated health. The risk of elective cesarean section and emergency cesarean section was 72% (RR= 1.72, 95% CI 1.09– 2.7) and 91% (RR= 1.91, 95% CI 1.04- 3.48) higher in mothers with bad self-rated health, respectively.Conclusion Our findings showed that self-rated health during pregnancy may effect cesarean section. Accordingly, the integration of screening for mental health morbidities into pregnancy health care packages are proposed.

“…Adverse effects of water pipe on fetal growth have been the focus of very limited research in Iran. Cross-sectional research shows that compared to non-smokers, the odds of intrauterine growth retardation would increase by 2-3.5 times in water pipe smokers (6,7). On the other hand, a negative correlation is reported between infant`s mean birth weight and extent of maternal cigarette smoking (8).…”

Background: Evidence regarding health effects of tobacco cessation during pregnancy is mainly restricted to cigarette while water pipe is the preferred method of tobacco smoking among women in the Middle-East. The present ‎study aimed to assess the effects of cessation of water pipe during pregnancy on ‎birth anthropometric measures in the south of Iran.Methods: Data on 1,120 singleton pregnancies (response rate=93.4%) from a population-based prospective cohort study in suburban communities in Bandar Abbas city was used. Based on water pipe ‎smoking status, the study subjects were categorized into: 1) those who never smoke water pipe ‎‎(never smoker); 2)those who stopped water pipe during pregnancy and resumed it postpartum (quitters); 3) those who continued smoking water pipe during their pregnancy (always smokers). The ‎Generalized Linear Models (GLMs) were utilized for the analyses.Results: Compared to never smokers, quitting water pipe in pregnancy decreased mean birthweight of infants by 99.30 ‎grams (β:-99.30, 95%CI:-204.35,-5.75‎) and an additional decrease of 37.83 grams occurred in infants of always smokers (β:-137.13‎;95%CI:-262.21,-‎‎12.05‎). Means of birth length ‎did not significantly differ among the three water pipe groups. Means of head ‎circumference, however, significantly increased by 0.79 centimeter in infants of always smokers (β:079,95%CI:0.13,1.45). ‎Conclusion: Quitting water pipe during pregnancy had positive effects on infant growth, especially birth weight. Awareness campaigns about health benefits of quitting water pipe during routine prenatal checkups and integration of active follow-up visits into prenatal care protocols for smoking mothers are provided.
