Grossesse et substances psychoactives : étude de prévalence de la consommation déclarée

Alcohol consumption during pregnancy and risk of small-for-gestational-age newborn

BACKGROUND

Contradictory results have been published on the association of alcohol consumption during pregnancy with perinatal outcomes, including the risk of small for gestational age newborn.

AIM

To determine whether alcohol consumption during pregnancy is associated with the risk of small for gestational age newborn.

METHOD

A case-control study with 518 pairs of pregnant Spanish women in five hospitals was conducted; cases were women with small for gestational age newborn and age-matched (±2years) controls were women with non-small for gestational age newborn. Data were gathered on demographic characteristics, socioeconomic status, toxic habits, and diet. Alcohol intake was recorded with a self-administered 137 food frequency questionnaire and with a personal interview, Alcohol intake was categorized -. Agreement in alcohol intake results between direct interview and frequency food questionnaire was evaluated with the Kappa index. Crude and adjusted odds ratios and their 95% confidence intervals were estimated by conditional logistic regression.

FINDINGS

Poor agreement was observed between food frequency questionnaire and personal interview results for both cases (κ=0.23) and controls (κ=0.14). A food frequency questionnaire-recorded intake of less than 4g/day was associated with a significantly lower odds ratios for small for gestational age newborn (odds ratios=0.62, 95% confidence intervals, 0.43-0.88), whereas an interview-recorded intake of <4g/day was not related to small for gestational age newborn (odds ratios=0.86, 95% confidence intervals, 0.49-1.54).

CONCLUSIONS

A very moderate alcohol intake during pregnancy may have a negative association with the risk of having a small for gestational age newborn.

[Obstetrical follow-up and perinatal prognosis in drug addict pregnant women]

OBJECTIVE

To identify the factors associated with a good obstetric follow-up and a good perinatal prognosis, in order to adapt the management of pregnant women with addiction to opiates.

METHODS

A retrospective study was carried out in our maternity between January 2012 and December 2014, including 104 women who were addicted to opiates, whether or not they were substituted, with or without associated consumptions, regardless of the term of delivery beyond 22 weeks of amenorrhea.

RESULTS

A good obstetrical follow-up was observed by 32.7% of women. The father's presence (OR=3.9; P=0.0113) and investment in pregnancy (OR=4.4; P=0.0029), as well as the desired character of the pregnancy (OR=4.5; P=0.0008) appeared to be associated with the quality of the observed follow-up. Preterm deliveries (11.8 versus 35.8%; P=0.0103), and social measures taken at the discharge of the newborn from the maternity (2.9 versus 24.3%, P=0.0057) were less frequent. A good perinatal prognosis was found for 29.8% of the cases. Associated consumptions <3 (OR=2.6 [1.1-6.2]; P=0.0281) confirmed by negative urine drug screening (OR=2.9 [1.1-7.8]; P=0.0307) were more numerous.

CONCLUSION

Although the follow-up and the perinatal prognosis of these pregnancies have improved considerably in recent years, it seems necessary to further optimize their management.

[Non-drug psycho-active substance use and pregnancy]

BACKGROUND

The consumption of psycho-active substances (PAS) by pregnant women is in a growing increase around the world. It is a major problem of public health in some countries due to serious and negative consequences for children and society as well as for pregnant women. This problem has also increased among women in Morocco. However, it is still neglected and underrated in the absence of any official statistical data. This is the first study leading to a better profiling of pregnant women who may consume psycho-active substances during their pregnancy; it would permit better medical and psychosocial care of both women and children.

OBJECTIVES

To determine the prevalence and the factors associated with the psycho-active substances used by pregnant women and describe their socio-demographic characteristics.

METHODS AND PATIENTS

A trans-sectional study was carried out from September to October 2010, including pregnant women consulting at the obstetrical service of the provincial hospital Moulay Abdellah in the city of Salé. The study included women who were pregnant or had recently given birth, and not having any serious mental disorders that could have upset their cognitive abilities. The data was collected through a straight questionnaire of 25 items specifying the socio-demographic characteristics, data about pregnancy and habits of using psycho-active substances.

RESULTS

One hundred and fifty pregnant women were included in the study. The majority of them (83.2%) were aged 20 to 40 years old, 94.6% were married, 96% were unemployed and depended on their spouses for their financial resources and 80% had normal domestic relationships (from average to good quality). Among the women, 31.3% of them reported traumatic events in the past. The prevalence of psycho-active substance consumption by the pregnant women of our sample was 11.3%. The used substances were tobacco (9.3%) and cannabis (4%). These women were more likely to have a low level of education (47.1 vs 16.5). They were victims of abuse or neglect in their past (82.3 vs 24.9), and their relationships with their spouses were bad (70.6 vs 13.5) with a lack of desired pregnancy (47.1 vs 27.8) and poor follow-up (47.1 vs 3.8). The results show statistically significant differences.

CONCLUSION

Not only should decision-makers draw attention to the seriousness of the problem because of the relatively high rate of psycho-active substance consumption, but also they should increase obstetric team's awareness to look systematically for psycho-active substance use.

[Pregnancy and substance use in France: a literature review]

OBJECTIVES

Substance use during pregnancy is an important public health issue. It requires identifying at-risk populations and risk perception among women.

MATERIALS AND METHODS

A literature review was conducted. It included French studies conducted since 2000 on substance use during pregnancy (tobacco, alcohol, marijuana, psychotropic drugs) and risk perception.

RESULTS

In France, in 2010, 24% of pregnant women smoke--17% in the 3rd trimester. Depending on studies, the prevalence of alcohol use ranged from 12 to 63% and binge drinking ranged from 1 to 7%; daily drinking was below 0.5%. Marijuana use ranged from 1 to 3%, and psychotropic drugs ranged from 2 to 4%. Little research has been dedicated to risk perception. Studies show a lack of awareness about the equivalence of risks between fermented and distilled beverages and about the risks of moderate smoking during pregnancy.

CONCLUSION

Data is lacking to characterize at-risk populations and mechanisms underlying risky behaviors.

[Perinatality in the context of addictions]

We must remove bad representations the medical team has upon the pregnant drug users and the same way in reverse. Opiate substitution treatment (OST) improves prenatal prognosis for both mother and child. There is no need to change OST for a stabilized woman discovering pregnancy. Nevertheless, buprenorphine appears to be first-range medication. OST posology is the most important for prenatal prognosis. Practician must never hesitate to adapt it whether increasing or fractionate it. Neonatal abstinence syndrome (NAS) is not linked with OST's posology. OST is not contra-indicated for breast-feeding. Breast-feeding should be encouraged. It does not treat or cure NAS but allows a skin-to-skin contact that could lessens an occurring withdrawal.

Management of cannabis use during pregnancy: an assessment of healthcare professionals' practices

PURPOSE

Because of the increase of cannabis use, healthcare professionals are more and more confronted with pregnancies which have been exposed to this drug. There may be health consequences during the course of pregnancy and also for the babies throughout their development. We have made a study in order to evaluate practices of detection and care for pregnant women who use cannabis.

METHODS

A questionnaire was sent to all gynaecologists (GYNs), obstetricians (OBs) and midwives (MWs) in the district of Loire-Atlantique and to a 20% randomized sample of general practitioners (GPs).

RESULTS

The participation rate was 60.1%. Only 51.4% of healthcare professionals asked their patients about drugs use and 68.1% didn't feel informed enough about the risks of cannabis use during pregnancy. There was a significant difference between the healthcare professionals who deliver babies (OBs and MWs) and those who only do prenatal consultations (GYNs and GPs). The first group question their patients about the use of cannabis more often (69.1% versus 39.8%; p = 0.01), and also feel more informed about the risks of cannabis use during pregnancy (42.0% versus 24.4%; p = 0.025).

CONCLUSIONS

Healthcare professionals who supervise childbirth have a more accurate perception of the risk related to the consumption of cannabis during pregnancy. But preventive action must be taken early on because the lack of early identification at the beginning of pregnancy represents a public health problem. After observing the results we feel there is a strong need for training for all practitioners.

[Maternal and obstetrical data in a retrospective cohort of 170 newborns from polydrug using mothers, in the Paris area, 1999-2008]

OBJECTIVES

Polydrug use in pregnancy is harmful. This survey aimed to explore the issue of the associations of substances during pregnancy and to determine the consumer profiles.

PATIENTS AND METHODS

One hundred and seventy newborns whose mothers were psychoactive substances users were identified over the period 1999 to 2008. The data relating to maternal consumption, their reproductive history, and their living environment were collated.

RESULTS

At the end of their pregnancy, the mothers reported using on average 3.14 substances. Three profiles were determined: 65 women were heroin users or had consumed it in their lifetime and were currently on substitution treatment, and had a very unfavourable social living environment; 30 women were mainly consumers of alcohol, with or without benzodiazepines or other psychotropic drugs, and had a history of abortions; 75 women were mainly tobacco and cannabis smokers, with or without substitution treatment, had good social living conditions and had wanted the pregnancy.

CONCLUSION

Polydrug use increases the risk for the women to avoid prenatal care and is often linked with a history of abortions.
