Pregnancy complications from smoking Smoking during pregnancy — effects on the fetus Problems at birth due to smoking during pregnancy Smoking and breastfeeding Smoking during pregnancy can cause problems for your child in later life Pregnancy and quitting smoking Where to get help.

Pregnancy complications from smoking Some of the pregnancy complications more commonly experienced by women who smoke include: ectopic pregnancy — this is pregnancy outside the uterus, usually in the fallopian tube fetal death — death of the baby in the uterus stillbirth spontaneous abortion — known as miscarriage problems with the placenta, including early detachment from the uterine wall and blocking the cervical opening placenta previa premature rupture of the membranes premature labour.

Smoking during pregnancy — effects on the fetus If you are pregnant, every time you smoke a cigarette, it cuts down oxygen to your unborn baby and exposes them to a cocktail of chemicals, including chemicals that cause cancer.

Problems at birth due to smoking during pregnancy Some of the problems caused by smoking during pregnancy include: increased risk of premature birth increased risk of miscarriage and infant death lower birth weight — on average, about to grams less than normal up to three times the risk of sudden unexpected death in infancy SUDI.

Smoking and breastfeeding Over two-thirds of women who quit when they are pregnant resume smoking after their babies are born. Some of the problems caused by smoking while breastfeeding include: Some of the chemicals in cigarettes can pass from you to your baby through your breastmilk. Smoking can reduce your milk production. Health effects may include: weaker lungs higher risk of asthma low birth weight, which is linked to heart disease, type 2 diabetes and high blood pressure in adulthood increased risk of being overweight and obese in childhood increased risk of attention deficit hyperactivity disorder ADHD.

Pregnancy and quitting smoking Ideally, a pregnant woman should stop smoking. Nicotine replacement therapy during pregnancy It is recommended that you first try to quit without medication.

Cigarette smoking carries a threat both to the expecting mother and her newborn. Data on the prevalence and predictors of smoking during pregnancy is limited in Canada. Therefore, the study aims to assess the prevalence of smoking during pregnancy and its associated risk factors throughout the Canadian provinces and territories.

The outcome was ever smoking during the thirst trimester of pregnancy. Socio-economic factors, demographic factors, maternal characteristics, and pregnancy related factors that proved to be significant at the bivariate level were considered for a logistic regression analysis.

Bootstrapping was performed to account for the complex sampling design. The sample size was 6, weighted to represent 76, Canadian women.

The prevalence of smoking during pregnancy was Regression analysis revealed that mothers who smoked during pregnancy were more likely to be of low socio-economic status, non-immigrant, single and passive smokers during pregnancy. While the age of the mother's first pregnancy was negatively associated with smoking during pregnancy, the mother's current age was positively associated with it.

Smoking during pregnancy is still prevalent among Canadian women. The findings may be useful to enhance smoking prevention programs and integrated health promotion strategies to promote positive health behaviors among disadvantaged pregnancies. Peer Review reports. Tobacco products are responsible for many complications including tobacco-induced abortions, deaths from perinatal disorders [ 1 ], newborns requiring admission to neonatal intensive care unit [ 2 ], low-birth weight infants [ 3 ], and deaths from Sudden Infant Death Syndrome [ 4 ].

Furthermore, cigarette smoking increases the risk of infertility and conception delay [ 5 ], as well as harmful pregnancy outcomes, such as premature rupture of membranes [ 6 ], placenta previa [ 7 ], abruptio placenta [ 8 ], stillbirth [ 4 ], and preterm delivery [ 9 ].

The prevalence of smoking among pregnant women has been shown to vary across different countries. For example, prevalence rates range from 9. During the same period, however, a study conducted in three Southern Ontario Health Units revealed that Data taken from revealed that, in Winnipeg, From , the overall prevalence of smoking just before delivery in Nova Scotia was Internationally, predictors of smoking among pregnant women have been well investigated.

Studies found that age, education, ethnicity, martial status, alcohol consumption, work status, and the mother's reproductive history are associated with smoking during pregnancy [ 11 , 17 — 19 ]. In Canada, pregnant smokers were more likely to be under 25 years of age [ 14 ], to have lower income levels [ 20 ], to be unmarried [ 20 ] and to have others in the household who smoked [ 21 ]. Moreover, Canadian women who were pregnant with their first child and who consumed alcohol during their pregnancy were also more likely to relapse to smoking during pregnancy [ 22 ].

Despite the well known and detrimental effects of smoking, it remains prevalent among pregnant women. In order to determine the groups of women that are at higher risk of smoking and to tailor appropriate interventions, the identification of prevalence and predictors is crucial.

Data on the prevalence and predictors of smoking during pregnancy, however, is limited in Canada. To our knowledge, only two studies assessed smoking during pregnancy at the national level [ 13 , 22 ].

Smoking during pregnancy, however, was assessed within 5 years in the past, which increases the chance of recall bias. Both national studies excluded mothers in the northern territories and investigated limited demographic and socio-economic predictors.

The present study, however, uses data from a recent specialized survey on pre and post delivery experiences among mothers residing in both the Canadian provinces and the territories. It aims to examine and assess the prevalence of smoking during pregnancy and the potential socio-economic, demographic maternal and pregnancy related risk factors. The MES study is a nationwide survey that assessed pregnancy, delivery and postnatal experiences of mothers and their children.

Participants eligible for the study were women aged 15 years and above, who had singleton live births between the period of February 15, and May 15, in the provinces of Canada and between November 1, and February 1, in the territories of Canada and who lived with their baby at the time of data collection.

A stratified random sample of 8, Canadian women was selected without replacement from the Canadian Census of Population. Around 8, women were estimated to have met the eligibility criteria of the study.

A total of 6, women, however, responded to the survey. Non-response to the survey was mainly from inability to establish contact with the mothers. Prior to data collection, an introductory letter and survey pamphlet were mailed to the women and invited them to participate in the survey.

Then the data was collected through telephone interviews using a computer-assisted telephone interview application. In an attempt to recruit the highest number of mothers possible, a total of 25 calls per each case were made during different days of the week and different hours of the day.

The MES questionnaire was also available in 15 languages. Majority of the interviews were conducted between the 5 th and 9 th month after delivery and lasted on average 45 minutes. The study has been previously described in other references [ 31 , 32 ]. The main outcome of the study is smoking during pregnancy defined as ever smoking during the last three months of pregnancy.

This variable was measured based on the question "During the last 3 months of your pregnancy, did you smoke daily, occasionally, or not at all? Other considered smoking related variables were smoking before pregnancy assessed by the question "In the three months before your pregnancy, or before you realized you were pregnant, did you smoke daily, occasionally or not at all?

The response categories for both questions were daily, occasionally and not at all. Similar to smoking during pregnancy, daily and occasional respondents were grouped as smokers. The number of cigarettes smoked was also considered.

For daily users, the question was: "How many cigarettes do you smoke each day? For occasional smokers, on the other hand, it was: "On the days that you do smoke, how many cigarettes do you usually smoke? A wide range of independent variables were investigated as potential predictors of smoking during pregnancy.

These variables were: i socio-economic factors: maternal years of education, total household income, maternal work status during pregnancy and place of residence urban vs.

All the variables, except for mother's stress level, were directly self-reported by the mother. The mother's stress level, however, was measured through a set of 13 questions that examined the mother's experience of 13 specific stressful events in the past 12 months before the birth of her selected child.

The answers for these questions were categorised as "Yes" or "No". Consequently, the sum of the "Yes" responses was calculated for each mother to represent the number of stressful events experienced [ 32 ].

For more information, the MES questionnaire is available online [ 34 ]. The prevalence of smoking was estimated through population weights and examined across all the Canadian provinces and territories.

Population weights estimate the number of people not selected in the sample that have been represented by each person in the sample. It also takes into consideration non-response in the survey [ 32 ].

At the bivariate level, differences in the proportion of smokers was assessed among the different levels of each predictor using normalized weights. Factors that proved to be significant at the bivariate level were considered for a multivariate logistic regression analysis. Population weights, normalized weights and bootstrap weights were all created by Statistics Canada and provided with the MES data file. The sample size for the population analyzed in this study was 6, weighted to represent 76, Canadian women.

Table 1 presents the estimated population and distribution of smoking practices before, during and after pregnancy. The proportion of women who smoked before, pregnancy was The prevalence of smoking during pregnancy, however, was Most regions in Canada displayed relatively similar smoking rates during pregnancy except for the Northern Territories The prevalence of smoking, on the other hand, was least prevalent in British Columbia 8.

Unadjusted and adjusted associations between smoking during pregnancy and potential factors are illustrated in Table 2. All variables significant at the bivariate level were considered for a logistic regression model.
