“…Ціла низка досліджень переконливо дово дить зв'язок паління під час вагітності з наро дженням дітей із малою масою тіла [15,23,24,25,45]. Найчастіше такі малюки наро джувалися у жінок, що палили у першому та другому триместрі вагітності.…”

“…Найчастіше такі малюки наро джувалися у жінок, що палили у першому та другому триместрі вагітності. Тоді як немовля та, матері яких починали палити тільки напри кінці терміну гестації, не мали достовірних роз біжностей у вазі при народженні з дітьми кон трольної групи [15,17]. Цікавим є той факт, що народження дітей з низькою масою тіла достовірно частіше відмічалося серед жінок, які зазнавали впливу тютюнового диму пасивно, а не палили самі, що підтверджує негативний вплив навіть малих доз токсичних речовин, які виділяються під час цього процесу [21].…”

“…Такі ефек ти тютюнового диму були пов'язані зі зменшен ням активність ендотеліальної NO синтази у кровоносних судинах плода, що сприяло зат римці його зростання, яка відображалася у зменшенні наростання ваги, довжини і окружності голови та мала оборотній характер. Також серед причин такого стану можна зазна чити вищий пренатальний гіпоксичний стрес плода під впливом нікотину, що підтверджено низкою експериментів [15,24].…”

Проведено огляд літератури, присвяченої патологічним наслідками паління жінки під час вагітності на стан здоров'я її дитини в подальшому. Наведені сучасні дані про розповсюдження тютюнопаління в цілому та серед окремих категорій населення. Описано зв'язок даного шкідливого фак тору із низкою патологічних станів дитини, зокрема із недоношеністю, низькою масою тіла дитини при народженні, затримкою внутрішньоутробно го розвитку плода, вищим ризиком виникнення синдрому раптової дитячої смерті, вищою частотою захворювань органів дихання у нащадків. Особлива увага приділена опису ролі токсинів тютюнового диму в епігенетичній модифікації процесів метилювання ДНК генів плода, що сприяє глиб шому розумінню механізмів впливу паління на стан здоров'я людей. Ключові слова: тютюнопаління, вагітність, новонароджений, недоношеність, затримка внутрішньоутробного розвитку.

“…[10] The escalating numbers of smokers cause grave complications in both pregnant women and infants by passive tobacco exposure. [11][12][13] Studies have stated that although many pregnant women never smoke, they still have great chances to expose to SHS and THS, [14] especially smoking from their spouses. A study in Sichuan province, China, has shown that 75.1% of non-smoking pregnant women are victimized due to chronic smoking habits of respective spouses.…”

Background With the increase of the number of smokers, tobacco exposure among pregnant women is becoming more and more common. Though that pregnant women exposed to first-hand smoke and second-hand smoke are susceptible to physiological and psychological health issues has been proved in previous studies, there are no enough studies focus on the impact of third-hand smoke. This study aimed to assess and compare health-related quality of life for pregnant women with exposure to first-hand smoke, second-hand smoke, third-hand smoke and non-exposure to tobacco in mainland China. Methods National-based cross-sectional study is based on a questionnaire survey which collects information including demographics, smoking behaviors and self-evaluation. All questionnaires were delivered and collected from August to September 2019. EuroQol group’s visual analog scale and EuroQoL Five-dimension Questionnaire were used to collect data in mainland China. Results Totally, 15682 pregnant women were included in this study, among which non-exposure to smoke were 7564 (48.2%), exposed to first-hand smoke, second-hand smoke and third-hand smoke were 89 (0.6%), 2349 (15.0%), and 5680 (36.2%) respectively. Pregnant women without tobacco exposure had the highest EuroQol group’s visual analog scale score (mean value=85.4[SD=14.0]), while those with first-hand smoke had the lowest score (mean value=77.4[SD=22.2]). Among all five dimensions of EuroQoL Five-dimension Questionnaire, there were significant differences of EQ-index among groups with different tobacco exposure in usual activity and anxiety or depression dimensions (p<0.001). Conclusions Third-hand smoke exposure had close relationship with low health-related quality of life in pregnant women. Moreover, second-hand smoke exposure significantly led more problems on mental dimension of pregnant women.

“…The adverse effect of passive smoking leading to pregnancy complication and mortality is well documented (12)(13)(14). Cigarette smoke contains more than 3000 toxic substances that result in damage of the placenta particularly in the membrane compartments (15).…”

A study was undertaken to estimate the amount oxygen that can diffuse across the placenta of the passive smoking mothers in an Indo-Asian population. A total of 24 human term placentas, 11 from mothers exposed to tobacco smoke and 13 from those not exposed to tobacco smoke were collected for estimating weight, surface area and volume term placentas. Five placentas from each of the groups were used for estimating the various parameters for calculating the oxygen-diffusing conductance. A random sampling technique at 7 levels of tissue preparation was adopted.Cotyledons were cut into blocks and each block was further cut into upper (maternal), middle (foeto-maternal) and lower (foetal) components. Semithin sections, 1 m thick, stained using a modified toluidine was viewed and the images were analysed. A Merz grid was used to estimate the vascular volumes, exchange surface areas and tissue diffusion distances for calculation the oxygen-diffusing conductance of the placenta. These were combined with physicochemical quantities (oxygen-haemoglobin reaction rates and tissues oxygen diffusion coefficients) obtained from literature in order to estimate the partial conductance of the six tissue compartments of the oxygen pathway. The present study demonstrates that there is no significant difference in the total oxygen-diffusing conductance in the placenta of passive smokers and those not exposed to tobacco smoke. However, the significant increase in the foetal capillaries and foetal erythrocytes conductance suggests that an adaptive mechanism in the foetal part of the placenta may be occurring to ensure adequate oxygen to the foetus
