Is Preconception Substance Use Associated With Unplanned or Poorly Timed Pregnancy?

Interconnections between unintended pregnancy, alcohol and other drug use, and pregnancy, birth, infant, childhood and socioeconomic outcomes: a scoping review

BACKGROUND

Unintended pregnancy (UIP) and substance use disorder share underlying root causes with similar impacts for women and their offspring in pregnancy, birth and beyond. Furthermore, intoxication with alcohol and other drugs (AOD) increases the risk of UIP.

OBJECTIVES

To assess the available evidence on associations between UIP and health, social and economic outcomes, in women who use AOD.

SEARCH STRATEGY

The review utilised the Joanna Briggs Institute Methodology for Scoping Reviews and PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) reporting guidelines. The search was conducted across multiple databases, including Scopus and Medline, and limited to studies published between January 2000 to June 2023.

SELECTION CRITERIA

Studies reporting on interactions between AOD use and UIP, and pregnancy, birth, infant, childhood, social or economic outcomes. All patterns and types of AOD use, except isolated use of tobacco, were included. Studies were available in English and conducted in high-income countries.

DATA COLLECTION AND ANALYSIS

Selected articles were reviewed, and data collected by two independent reviewers using a standardised data extraction sheet. Findings were summarised and reported descriptively.

MAIN RESULTS

A total of 2536 titles and abstracts were screened, 97 full texts were reviewed, and three studies were selected for inclusion in the scoping review. There was heterogeneity in types and patterns of AOD use, differences in study design and tools to assess pregnancy intention, and each focused on disparate outcomes. No study assessed or reported on birth outcomes.

CONCLUSION

There is a paucity of data examining the intersection between AOD use and UIP and further research is needed.

Association between adverse childhood experience and unintended pregnancy among Japanese women: a large-scale cross-sectional study

Unintended pregnancy (UP) can negatively impact the health of mothers, children, and families. While Adverse Childhood Experiences (ACEs) are increasingly known to affect sexual health, the influence on pregnancy intention is not fully understood. This study examines the relationship between ACEs and UP and explores other related factors, using 5049 pregnant and postpartum women data from the Japan COVID-19 and Society Internet Survey (JACSIS). We measured participants' pregnancy intentions, ACEs, family functioning, and social network size. Logistic regression analysis provided odds ratios and 95% confidence intervals (CI). The prevalence of UP was approximately 16.5% (n = 893). Cumulative ACEs were consistently associated with UP, even after adjusting for intermediate variables in adulthood. The odds ratio for UP with a single ACE was 1.00 (CI: 0.82-1.21) but rose significantly with multiple ACEs: 1.39 (CI: 1.10-1.76) with double, 1.38 (CI: 1.02-2.86) with triple, and 1.81 (CI: 1.37-2.39) with more. Additionally, bad family functioning and lack of social networks emerged as contributors to UP. In conclusion, this study showed that ACEs are potentially correlated with UP. A deeper understanding of the transition from childhood experiences to UP is important for health interventions, necessitating further investigation.

Prevalence and predictors of sex under the influence of psychoactive substances among young people in informal settlements in Kampala, Uganda

BACKGROUND

The use of psychoactive substances such as alcohol, heroin and marijuana is associated with negative health outcomes such as sexual violence and unintended pregnancies, and risky sexual behaviours. Although there is evidence linking psychoactive substance use and risky sexual behaviours such as inconsistent condom use and multiple sexual relationships, there is limited data on sex under the influence of psychoactive substances among young people. This study aimed to investigate the prevalence and predictors of sex under the influence of psychoactive substances among young people in informal settlements in Kampala, Uganda.

METHODS

A cross-sectional study was conducted among 744 sexually active young psychoactive substance users in informal settlements in Kampala, Uganda. Data were collected through face-to-face interviews using a digitalized structured questionnaire, preloaded on the Kobocollect mobile application. The questionnaire captured data on the socio-demographic characteristics of the respondents, history of psychoactive substance use, and sexual behaviours. Data were analysed using STATA Version 14.0. A modified Poisson regression model was used to determine the predictors of sex under the influence of psychoactive substances.. Adjusted prevalence ratios at a p-value value ≤ 0.05 with a 95% confidence interval were considered.

RESULTS

About 61.0% (454/744) of the respondents had had sex under the influence of psychoactive substances in the last 30 days. The predictors of sex under the influence of psychoactive substances were being female (PR 1.18, 95% CI: 1.04-1.34), being 20-24 years of age (PR: 1.22, 95% CI: 1.04-1.44), being married (PR 1.15, 95% CI: 1.01-1.31) or divorced/separated (PR 1.43, 95% CI: 1.26-1.61), not living with biological parents or guardians (PR 1.22, 95% CI: 0.99-1.50), earning 71 USD and below (PR 0.86, 95% CI: 0.79-1.03) and using alcohol (PR 1.43, 95% CI: 1.25-1.69), marijuana (PR 1.16, 95% CI: 1.02-1.31) and khat (PR 1.25, 95% CI: 1.10-1.42) in the last 30 days.

CONCLUSION

The study found that a high proportion of sexually active young people in informal settlements in Kampala, Uganda had engaged in sex under the influence of psychoactive substances in the past 30 days. The study also identified several factors associated with sex under the influence of psychoactive substances, including being female, being aged 20-24 years, being married or divorced or separated, not living with biological parents or guardians, and using alcohol, marijuana, or khat in the past 30 days. Our findings suggest the need for targeted sexual and reproductive health programs that incorporate risk-reduction interventions aimed at reducing sex under the influence of psychoactive substances, especially among females and those who do not live with their parents.

Sex in the Context of Substance Use: A Study of Perceived Benefits and Risks, Boundaries, and Behaviors among Adolescents Participating in an Internet-Based Intervention

Little research has examined adolescents' perspectives of sex with substance use. This study examined (1) adolescents' perceived benefits and risks of sex with substance use, as well as boundaries; (2) the potential for positive and negative social influences among adolescents when they discuss these topics; and (3) whether exposure to health-promoting content is associated with trajectories of sex with substance use over a 6-month period. To address the first two objectives, 176 comments were analyzed from 71 adolescents (90% female) aged 14-18 years who participated in an Internet-based sexual health promotion intervention and posted to at least one message board addressing sex with substance use. Adolescents' perceived benefits and risks of sex with substance use primarily reflected concern for the experience of sex in the moment; perceived risks and boundaries primarily reflected concern for the ability to develop and maintain meaningful relationships. Comments of 63% and 22% of adolescents, respectively, were evaluated to have potential for health-promoting and risk-promoting social influence. To address the third objective, trajectories of self-reported sex with substance use were compared between 89 intervention and 54 control participants. No significant differences were observed. However, a dose-response effect was observed; intervention participants who completed less than one third of assigned tasks reported increases in sex with alcohol or marijuana use over time, while no marked changes or much smaller changes in sex with substance use were observed among intervention participants who completed one third or more tasks. Implications for prevention and intervention programs are discussed.

Association of Prepregnancy Substance Use and Substance Use Disorders with Pregnancy Timing and Intention

Background: Limited research exists on the association between substance use disorders (SUDs) and dimensions of pregnancy intention. This study sought to examine the independent relationships between prepregnancy substance use and SUDs with pregnancy timing and intentions. Materials and Methods: Secondary analysis of data from three prenatal care sites in Connecticut, Massachusetts, and Michigan, 2016-2017. Associations were estimated using modified Poisson regression with robust error variance to calculate adjusted prevalence ratios (aPRs) and 95% confidence intervals (CIs), controlling for relevant covariates. Results: The total sample size was 1115 women. Respectively, 61.1% and 15.5% of women used any substance in the 30 days prepregnancy or had any SUD in the past 12 months. After adjustment, any prepregnancy substance use was associated with a reduced likelihood of a well-timed (aPR 0.85; 95% CI: 0.77-0.93) and intended (aPR 0.80; 95% CI: 0.72-0.89) pregnancy; similarly, any SUD was associated with a reduced likelihood of a well-timed (aPR 0.66; 95% CI: 0.55-0.80) and intended (aPR 0.79; 95% CI: 0.67-0.93) pregnancy. Conclusions: Women with prepregnancy substance use or SUD have decreased prevalence of well-timed and intended pregnancies. Greater efforts are needed to address substance use and family planning in routine, well-woman, prenatal, and postpartum care.

Preconception Substance Use and Risk of Unintended Pregnancy: Pregnancy Risk Assessment Monitoring System 2016-17

OBJECTIVE

This study examined the association between preconception substance use and unintended pregnancy in a large, nationally representative sample of women.

METHODS

In this cross-sectional study, we used data from the Pregnancy Risk Assessment Monitoring System (PRAMS) comprising, 74,543women who had birth during 2016-17. Logistic regression was used to assess the independent association of unintended pregnancy overall and by subtypes to preconception substance use (smoking and other nicotine/tobacco use, alcohol consumption, and use of cannabis, illicit/recreational drugs) and specific medication including prescription opioids, antidepressants and over the counter pain relief.

RESULTS

Overall, 41% of pregnancies were unintended. Nearly 57% of participants reported alcohol consumption during the preconception period, with 32% indicating binge drinking, 17% reported preconception smoking, and 10% cannabis use. Unintended pregnancy was significantly associated with substance use, including smoking (adjusted odds ratio [AOR]:1.5, 95% confidence interval [CI]: 1.4-1.6); as well as the use of other nicotine/tobacco (AOR:1.4, 95% CI: 1.3-1.5); cannabis (AOR: 1.9, 95% CI: 1.5-2.3); illicit/recreational drugs (AOR:1.7, 95% CI: 1.2-2.4), prescription opioids (AOR:1.4, 95% CI: 1.02-1.9), and prescription antidepressants (AOR 1.8, 95% CI: 1.1-3.0). The likelihood of unintended pregnancy was significantly elevated with heavy smoking, heavy alcohol consumption, and binge drinking. Analyses by unintended pregnancy subtype yielded similar results.

CONCLUSIONS

Preconception substance use was significantly and positively associated with unintended pregnancy. Evidence-based interventions are needed addressing substance use behavior and effective contraceptive use to prevent unintended pregnancy and related adverse effects on maternal and child health.

Missingness patterns in a comprehensive instrument identifying psychosocial and substance use risk in antenatal care

BACKGROUND

Psychosocial vulnerabilities (e.g. inadequate social support, financial insecurity, stress) and substance use elevate risks for adverse perinatal outcomes and maternal mental health morbidities. However, various barriers, including paucity of validated, simple and usable comprehensive instruments, impede execution of the recommendations to screen for such vulnerabilities in the first antenatal care visit. The current study presents findings from a newly implemented self-report tool created to overcome screening barriers in outpatient antenatal clinics.

METHODS

This was a retrospective chart-review of 904 women who completed the Profile for Maternal & Obstetric Treatment Effectiveness (PROMOTE) during their first antenatal visit between June and December 2019. The PROMOTE includes the 4-item NIDA Quick Screen and 15 additional items that each assess a different psychosocial vulnerability. Statistical analysis included evaluation of missing data, and exploration of missing data patterns using univariate correlations and hierarchical clustering.

RESULTS

Three quarters of women (70.0%) had no missing items. In the entire sample, all but four PROMOTE items (opioid use, planned pregnancy, educational level, and financial state) had < 5% missing values, suggesting good acceptability and feasibility. Several respondent-related characteristics such as lower education, less family support, and greater stress were associated with greater likelihood of missing items. Instrument-related characteristics associated with missing values were completing the PROMOTE in Spanish or question positioning at the end of the instrument.

CONCLUSIONS AND IMPLICATIONS

Conducting a comprehensive screening of theoretically and clinically meaningful vulnerabilities in an outpatient setting is feasible. Study findings will inform modifications of the PROMOTE and subsequent digitisation.

Social support reduces the risk of unintended pregnancy in a low-income population

Almost half of all pregnancies (45%) in the United States (US) are unintended, with the highest concentration in women with low incomes. Targeted research is warranted to identify risk and protective factors that influence pregnancy intention to improve maternal/child health.

PURPOSE

To identify individual and interpersonal level associations to pregnancy intention to use as leverage points to build resilience.

METHOD

A cross-sectional, secondary analysis of Medicaid eligible pregnant women in Kentucky (n = 309).

RESULTS

Sixty-two percent reported their current pregnancy was unintended. Older age, partnered, negative drug screen, and increased social support were associated with decreased odds of unintended pregnancy. For every 1 unit increase of belonging and tangible social support, women were 13% and 14% (respectively) less likely to have an unintended pregnancy (OR = 0.87, 95% CI = 0.78-0.97, p = .011, OR = 0.86, 95% CI = 0.77-0.95, p = .005). A positive drug screen was associated with an almost three-fold increase in the odds of unintended pregnancy (OR = 2.88, 95% CI = 1.49-5.58, p = .002).

CONCLUSION

Public health nurses can play a critical role in reducing unintended pregnancy rates by promoting social support, inclusion, and acceptance. There remains a critical need to identify barriers and facilitators to pregnancy planning for persons who use illicit drugs.

Association between pregnancy intention and smoking or alcohol consumption in the preconception and pregnancy periods: A systematic review and meta-analysis

AIMS

To investigate the association between pregnancy intention and smoking or alcohol consumption in preconception and pregnancy periods.

BACKGROUND

Suboptimal lifestyle such as smoking and alcohol consumption can lead to devastating outcomes on the maternal and foetus. Pregnancy intention exerts a significant effect on promoting healthy lifestyle behaviours. However, no reliable evidences confirmed pregnancy intention was associated with smoking and alcohol consumption before and during pregnancy.

DESIGN

Systematic review and meta-analysis.

METHODS

We performed a comprehensive search from databases including PubMed, Cochrane, Web of Science, IEEE Xplore, MEDLINE, ProQuest and Scopus from the inception of these databases up to November, 2020. All eligible studies exploring the association between pregnancy intention and smoking or alcohol consumption were included. The fixed- or random effect pooled measure was used to estimate the odds ratio (OR) or risk ratio (RR) and 95% CI. In addition, the PRISMA checklist was used in this meta-analysis.

RESULTS

A total of 23 studies were included in this systematic review and meta-analysis. During pregnancy, the findings suggested that women with unplanned pregnancy were 68% more likely to consume cigarettes (OR = 1.68, 95% CI = 1.44-1.95) and 44% more likely to consume alcohol (OR = 1.44, 95% CI = 1.15-1.81) than those women with planned pregnancy. Meanwhile, during preconception, women with unplanned pregnancy were 30% more likely to consume cigarettes (OR = 1.30, 95% CI = 1.10-1.53) and 20% more likely to consume alcohol (OR = 1.20, 95% CI = 1.01-1.42) than those women with planned pregnancy.

CONCLUSION

The findings suggested that women with unplanned pregnancy were more likely to follow unhealthy behaviours such as smoking and alcohol consumption before and during pregnancy. Health professionals should consider the women's desire for pregnancy to decrease preconception and pregnancy smoking or alcohol consumption in future studies.

RELEVANCE OF CLINICAL PRACTICE

Pregnancy intention is the key determinant of smoking and alcohol consumption during preconception and pregnancy periods. Offering effective contraception in primary healthcare setting could prevent unplanned pregnancy. Meanwhile, popularising minimal alcohol consumption and comprehensive smoke-free legislation would be beneficial to improve reproductive outcomes.

A Review of Unintended Pregnancy in Opioid-Using Women: Implications for Nursing

BACKGROUND

Opioid use among reproductive-age women has greatly increased, resulting in high rates of opioid-exposed pregnancies, which are associated with negative outcomes, such as neonatal abstinence syndrome. Prevention of unintended pregnancy among opioid users is a critical pathway to reducing opioid-exposed pregnancies; however, little is known about pregnancy intention in this group. This article estimates the prevalence of unintended pregnancy among opioid-using women, thereby supporting efforts to develop interventions to reduce unintended pregnancy.

METHODS

A systematic literature search was conducted in PubMed, Web of Science, PsycINFO, and CINAHL, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses framework. Reference lists of articles were searched. Eligibility criteria included reported unintended pregnancy rates within a population of opioid-using women of reproductive age. The search was completed in July 2018 and updated in October 2019.

RESULTS

We identified 115 citations, screened 64 titles/abstracts, reviewed 31 full-text articles, and included 12 articles for this review. Rates of unintended pregnancy in opioid users were estimated in two ways, across the lifetime and for a current pregnancy, depending on study samples. Rates for both groups were high, with rates among currently pregnant opioid-using women (85%) compared with 45% among the general population.

CONCLUSIONS AND IMPLICATIONS

Unintended pregnancy rates in opioid-using women were strikingly high, indicating a critical need for intervention. Routine inclusion of pregnancy planning in opioid treatment care is indicated. Education regarding contraception and opioid treatment services is essential for nurses in these settings. Family planning and opioid treatment efforts can be optimized by care coordination, with focus on nurse training for screening and patient education.

Prevalence of STIs, sexual practices and substance use among 2083 sexually active unmarried women in Lebanon

Access to sexual and reproductive health in conservative communities and in the MENA region are particularly limited and, as such, increase women's vulnerability to unwanted pregnancies, unsafe abortions, and sexually transmitted infections (STIs). The aim was to assess the prevalence of STIs, sexual practices, recreational drug-use and their possible associations among cisgender unmarried women residing in Lebanon. Data on demographics, sexual practices and substance-use were collected from 2083 unmarried cisgender women who voluntarily attended a sexual health clinic in Lebanon between 2015 and 2019. They tested for HIV, Hepatitis B, Hepatitis C and Syphilis through rapid testing. Other infections (genital warts, Neisseria gonorrhea/Chlamydia trachomatis) were screened for. Regression models were computed between variables. There were two cases of HIV, one of Hepatitis B and syphilis, and no cases of Hepatitis C. Genital warts were present in 15% and symptoms indicative of Neisseria gonorrhea/Chlamydia trachomatis in 14%. Inconsistent condom-use (81%) was significantly associated with number of partners (adj. OR: 0.4). Inconsistent condom-use discussion with partners (33%) was significantly associated with unemployment (adj OR: 1.7), recreational drug-use (adj. OR: 1.4), and number of partners (adj. ORs 3.7-4.4). Unwanted pregnancies (11%) were significantly associated with age (adj. ORs 0.1-0.37), recreational drug-use (adj. OR: 2), using intrauterine device (adj. OR:2.9) and natural birth control methods (adj. OR: 2.4). Recreational drug-use (33%) was significantly associated with age (adj ORs 1.9-2.2), and smoking status (adj. OR: 0.6). The results indicate an urgent need for: (1) Accessible, non-stigmatizing, and inclusive sexual health services dedicated to women's sexual health; (2) Comprehensive and non-stigmatizing sexual health education for all, but especially women, in order to promote safer sexual practices and effective decision making with regards to contraception and condom-use.

Postpartum contraceptive planning of women with substance abuse disorders

BACKGROUND

Women with substance abuse disorders have lower use of contraception. Unplanned pregnancies increase risk of fetal exposure to addictive and teratogenic substances. Postpartum inpatient periods for these women can be challenging times to facilitate contraception planning.

OBJECTIVE

To explore postnatal contraceptive planning practices, patient preferences for contraception, and supply challenges, and to identify how clinical pharmacists may best provide care in this context.

SETTING

A tertiary maternity referral hospital in metropolitan Victoria, Australia (January 2015-December 2018).

METHOD

A retrospective cohort study was conducted on postnatal women with substance abuse disorders. Patients were excluded if they had delivered at another health service, had inadequate documented evidence of a substance abuse disorder, or had incomplete or unavailable medical records. Records were reviewed for demographic data, admission details, and documented contraceptive planning.

MAIN OUTCOME MEASURES

Documented contraceptive planning, patient contraception preferences and identified supply challenges.

RESULTS

Ninety-three women were included. Seventy-one (76.3%) had psychiatric disorders or impairments, and 92 (98.9%) had identifiable follow-up challenges (eg. Homelessness). Nine (9.7%) self-discharged/absconded. Eighty-seven (93.5%) had documented postnatal contraception discussions. Sixty-two of 87 (71.3%) considered a medicine/device, three (3.4%) preferred condoms, 10 (11.5%) considered sterilisation, 2 (2.3%) preferred no contraception, and 16 (18.4%) undecided. Etonogestral 68 mg implants were most commonly prescribed (28 of 42; 66.7%).

CONCLUSION

Inpatient postpartum periods for this cohort were characterised by psycho-social complexities, inconsistent contraceptive planning documentation, and patients seemingly unprepared to consider contraception. This study highlights a need for an earlier decision-making process and pragmatic counselling with antenatal pharmacists.

Adverse Childhood Experiences and Pregnancy Intentions among Pregnant Women Seeking Prenatal Care

BACKGROUND

This study examined whether adverse childhood experiences (ACEs) are associated with increased risk of having an unwanted or mistimed pregnancy.

METHODS

Women in two medical centers within an integrated health system were screened for ACEs during standard prenatal care (N = 745). Multinomial multivariable logistic regression analyses examined the associations of ACEs (count and type) with pregnancy intentions, adjusting for covariates.

RESULTS

Overall, 58.3% of pregnant women reported no ACEs, 19.1% reported one ACE, and 22.7% reported two or more ACEs; 76.2% reported wanting to get pregnant, 18.5% reported wanting to get pregnant but not at this time (i.e., mistimed pregnancy), and 5.2% reported not wanting to get pregnant at all (i.e., unwanted pregnancy). Having two or more (vs. 0) ACEs was associated with higher odds of an unwanted pregnancy (odds ratio, 2.60; 95% confidence interval, 1.19-5.68). Further, childhood loss of parent (odds ratio, 2.20; 95% confidence interval, 1.03-4.71) and neglect (odds ratio, 5.67; 95% confidence interval, 1.72-18.72) were each associated with higher odds of an unwanted pregnancy in separate analyses. ACEs count and type were not significantly associated with having a mistimed pregnancy.

CONCLUSIONS

Among women screened for ACEs during standard prenatal care, ACEs were associated with increased odds of having an unwanted pregnancy, but not a mistimed pregnancy. Additional research is needed to better understand the mechanisms through which ACEs and other individual, social, and contextual factors impact pregnancy intentions to better support women and provide appropriate resources to help prevent unintended pregnancies.

Maternal Characteristics Associated With Preconception Marijuana Use

INTRODUCTION

Given the increase of marijuana use among U.S. women, higher rates of unintended pregnancies among women who use marijuana, and potential consequences of maternal use, there is a need to identify factors associated with marijuana use in the period leading up to pregnancy. This study aims to provide estimates of preconception marijuana use and describe associations between preconception marijuana use and maternal characteristics among a population-based sample of recently delivered women in the U.S.

METHODS

This was an analysis of 2016 Pregnancy Risk Assessment Monitoring System data from 6 states (Louisiana, Maine, New Mexico, Vermont, Wisconsin, and Wyoming). Characteristics were compared between respondents who did and did not report marijuana use using chi-square tests and logistic regression models. Statistical analysis was performed in 2019 and 2020.

RESULTS

Approximately 8% of respondents reported that they had used marijuana in the month before pregnancy. After controlling for a number of factors, marital status, education level, parity, and living in a state with medical or recreational marijuana legalization or decriminalization remained independently associated with marijuana use. Those who reported marijuana use were 3-5 times more likely to also report symptoms of depression and tobacco and alcohol use before or during pregnancy than respondents who did not report marijuana use.

CONCLUSIONS

Reproductive-aged women who are intending pregnancy or likely to experience an unintended pregnancy should be asked about and encouraged to refrain from marijuana use, especially given the strong association with depressive symptomology and concurrent use of other substances, including tobacco.

Gender Differences in Factors Influencing Self-Efficacy Toward Pregnancy Planning among College Students in Korea

The purpose of this study was to examine factors influencing college students' self-efficacy toward pregnancy planning by gender using the health belief model (HBM). Utilizing a comparative descriptive design, a total of 819 college students were recruited. A survey was administered to gather information on health beliefs related to pregnancy planning, self-efficacy toward pregnancy planning, fertility knowledge, and general characteristics. The main variables were compared by gender. The factors influencing self-efficacy toward pregnancy planning were identified using hierarchical regression analysis. Female students (476) had lower self-efficacy toward pregnancy planning than male students (343). The significant factors influencing self-efficacy toward pregnancy planning in female students were: depression (β = -0.09, p = 0.030), fertility knowledge (β = 0.08, p = 0.025), barriers (β = -0.57, p < 0.001), and cues to action (β = 0.16, p < 0.001), whereas the corresponding factors in male students were benefits (β = 0.12, p = 0.020), barriers (β = -0.44, p < 0.001), and cues to action (β = 0.16, p = 0.001). The present study confirmed the suitability of the HBM as a conceptual framework for identifying factors influencing self-efficacy toward pregnancy planning. Based on the findings of this study, gender-based similarities and differences in factors influencing self-efficacy should be considered when taking steps to promote self-efficacy toward pregnancy planning among college students.

Is Periconceptional Substance Use Associated with Unintended Pregnancy?

Background: To evaluate the relationship between periconceptional (period before and/or after conception) substance use and unfavorable pregnancy contexts, including unintended pregnancy.

Materials and Methods: This is a cross-sectional analysis of English- or Spanish-speaking women aged 16–44 years with pregnancies <24 weeks' gestation presenting to pregnancy testing clinics and enrolled between June 2014 and June 2015. Participants self-reported periconceptional substance use (tobacco, alcohol, marijuana, and other illicit substances during the 3 months before enrollment), and pregnancy “contexts,” including pregnancy intention, wantedness, planning, timing, desirability, and happiness. Multivariable logistic regression was performed adjusting for potential confounding variables.

Results: We enrolled 123 women, averaging 27 ± 6 years, and mean gestational age 7.5 ± 3.0 weeks. Most participants were black, non-Hispanic (37%), or Hispanic (46%), and chose to complete the study in English (69%). Sixty-five percent participants reported use of one or more substances during prior 3 months: alcohol (54%), tobacco (31%), and marijuana (21%). In multivariate analysis, periconceptional alcohol use was associated with increased odds of unintended or ambivalent pregnancy and unwanted or mixed feelings regarding pregnancy (odds ratios [OR] = 3.29, 95% confidence interval [CI] 1.08–10.08 and OR = 2.81, 95% CI 1.07–7.36, respectively). Weekly or daily tobacco use was associated with unhappiness about pregnancy (OR = 7.56, 95% CI 1.65–34.51) and undesired or unsure pregnancy (OR = 4.00, 95% CI 1.14–14.06).

Conclusions: Periconceptional alcohol or tobacco use demonstrates increased odds of specific unfavorable pregnancy contexts, including pregnancy described as undesired, unintended, unwanted, and unhappiness with pregnancy. Primary prevention of periconceptional substance use and the negative effects of alcohol and tobacco may be improved by increasing contraception access for women at risk for unfavorable pregnancy contexts.

Identification of substance use disorders among pregnant women: A comparison of screeners

BACKGROUND

The purpose of this study is to evaluate five self-report, non-proprietary questionnaires in the identification of substance use disorders [including alcohol, cannabis, opioids, and stimulants] among pregnant women.

PROCEDURES

A total of 1220 pregnant women completed the NIDA Quick Screen, CRAFFT, Substance Use Risk Profile-Pregnancy (SURP-P), Wayne Indirect Drug Use Questionnaire (WIDUS), and the 5 Ps, as well as the MINI diagnostic interview for substance use disorders, which served as the reference standard. Measures of merit calculated for each screener included sensitivity, specificity, accuracy, and area under the receiver operating curve (AUROC).

MAIN FINDINGS

The participants were socioeconomically diverse, with a mean age of 29 years. Over 15% met diagnostic criteria for a substance use disorder. AUROCS for identifying any substance use disorder (including alcohol) ranged from a high of 0.75 for the CRAFFT (95% CI = 0.72-79) and 0.74 for the SURP-P (95% CI = 0.71-.78) to a low of 0.62 for the NIDA Quick Screen (95% CI = 0.59-.65). Overall accuracy of most tested measures was higher for identification of alcohol use disorders than for other substance use disorders (e.g., AUROCs for the CRAFFT and SURP-P for identifying alcohol use disorders were 0.78 and 0.77, respectively).

PRINCIPAL CONCLUSIONS

The CRAFFT and SURP-P showed modest ability to identify substance use disorders among pregnant women. Future research is needed to develop an ideal questionnaire set in the complicated societal context which includes increasing rates of use and potential sanction.
