Abstract BackgroundTo estimate Population Attributable Fractions (PAFs) and Generalized Impact Fractions (GIFs) for LBW following scenarios to remove or decrease prenatal use of caffeine or water pipe.Methods‎Using data of 861 pregnant women from a population-based prospective cohort study ‎in suburbs of Bandar Abbas city (2016-2018), PAFs and GIFs were calculated based on the relative risk scale. Practical interventional scenarios to reduce the exposure prevalence were developed for calculation of GIFs. ResultsThe cumulative incidence of LBW was 16.1%. An estimated 19% (95%CI: 6, 30%) of LBW neonates was attributed to dietary caffeine intake of >100 mg/day and 11% (95%CI: 8,14%) to water pipe smoking. Action plans to reduce caffeine intake and water pipe smoking suggested an avoidable burden of LBW cases of approximately 10.7% (95% CI: 6.6, 25.3%) and 5.7% ‎‎(95%CI: ‎5.0, 6.8%), respectively.‎ConclusionsWater pipe smoking and excessive consumption of caffeine during pregnancy decreased birth weight. Practical action plans to control water pipe smoking ‎and to prevent excessive intake of ‎caffeine ‎among pregnant women would substantially reduce LBW burden in the south of Iran. ‎

Abstract Background Evidence on health effects of tobacco cessation in pregnancy is mainly restricted to cigarette, while water pipe smoking is more prevalent 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 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. Birth measures were used according to infant`s vaccination cards. Study subjects were categorized into three subgroups based on water pipe ‎smoking status during pregnancy, including: 1) mothers who never smoke water pipe ‎‎(never smoker); 2)mothers who stopped water pipe during pregnancy and resumed it postpartum (quitters); 3) mothers who continued smoking water pipe regardless ‎of their pregnancy (always smokers). ‎Generalized Linear Models (GLMs) were utilized for the analyses. Results Compared to never smokers, quitting water pipe in pregnancy would decrease mean birthweight by 99.30 ‎grams (β:-99.30, 95%CI:-204.35,-5.75‎); while an additional decrease by 37.83 grams would occur in always smokers (β:-137.13‎;95%CI:-262.21,-‎‎12.05‎). Mean birth length ‎did not significantly differ among the three water pipe groups. Mean head ‎circumference, however, would significantly increase by 0.79 centimeter in 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. Some suggestions are provided including integration of information on health benefits of quitting smoking into routine prenatal healthcare services and development of awareness programs to encourage smokers to quit early in pregnancy.
