An integrative literature review of birth cohort and time period trends in adolescent depression in the United States

PURPOSE

The aim of this literature review is to examine evidence of time trends and birth cohort effects in depressive disorders and symptoms among US adolescents in peer-reviewed articles from January 2004 to April 2022.

METHODS

We conducted an integrative systematic literature review. Three reviewers participated at different stages of article review. Of the 2234 articles identified in three databases (Pubmed, ProQuest Central, Ebscohost), 10 met inclusion criteria (i.e., adolescent aged United States populations, included information about birth cohort and survey year, focused on depressive symptoms/disorders).

RESULTS

All 10 articles observed increases in depressive symptoms and disorders in adolescents across recent survey years with increases observed between 1991 and 2020. Of the 3 articles that assessed birth cohort trends, birth cohort trends were less prominent than time period trends. Proposed explanations for increases included social media, economic-related reasons, changes in mental health screening and diagnosis, declining mental health stigma, increased treatment, and, in more recent years, the COVID-19 pandemic.

CONCLUSIONS

Multiple cross-sectional surveys and cohort studies documented rising prevalence of depressive symptoms and disorder among adolescents from 1991 to 2020. Mechanisms driving this increase are still unknown. Research to identify these mechanisms is needed to inform depression screening and intervention efforts for adolescents.

Punitive legal responses to prenatal drug use in the United States: A survey of state policies and systematic review of their public health impacts

BACKGROUND

Punitive legal responses to prenatal drug use may be associated with unintended adverse health consequences. However, in a rapidly shifting policy climate, current information has not been summarized. We conducted a survey of U.S. state policies that utilize criminal or civil legal system penalties to address prenatal drug use. We then systematically identified empirical studies evaluating these policies and summarized their potential public health impacts.

METHODS

Using existing databases and original statutory research, we surveyed current U.S. state-level prenatal drug use policies authorizing explicit criminalization, involuntary commitment, civil child abuse substantiation, and parental rights termination. Next, we systematically identified quantitative associations between these policies and health outcomes, restricting to U.S.-based peer-reviewed research, published January 2000-December 2022. Results described study characteristics and synthesized the evidence on health-related harms and benefits associated with punitive policies. Validity threats were described narratively.

RESULTS

By 2022, two states had adopted policies explicitly authorizing criminal prosecution, and five states allowed pregnancy-specific and drug use-related involuntary civil commitment. Prenatal drug use was grounds for substantiating civil child abuse and terminating parental rights in 22 and five states, respectively. Of the 16 review-identified articles, most evaluated associations between punitive policies generally (k = 12), or civil child abuse policies specifically (k = 2), and multiple outcomes, including drug treatment utilization (k = 6), maltreatment reporting and foster care entry (k = 5), neonatal drug withdrawal syndrome (NDWS, k = 4) and other pregnancy and birth-related outcomes (k = 3). Most included studies reported null associations or suggested increases in adverse outcome following punitive policy adoption.

CONCLUSIONS

Nearly half of U.S. states have adopted policies that respond to prenatal drug use with legal system penalties. While additional research is needed to clarify whether such approaches engender overt health harms, current evidence indicates that punitive policies are not associated with public health benefits, and therefore constitute ineffective policy.

Longitudinal relationships among exclusionary school discipline, adolescent substance use, and adult arrest: Public health implications of the school-to-prison pipeline

PURPOSE

Exclusionary school discipline is an initiating component of the school-to-prison pipeline that is racialized and may lead to short- and long-term negative substance use and criminal legal outcomes. However, these impacts, and racial disparities therein, have not been well explored empirically at the individual-level.

PROCEDURES

We analyzed data from the National Longitudinal Study of Adolescent to Adult Health (1995-2009). We fit survey-weighted multivariable logistic regression models to estimate reciprocal relationships between exclusionary discipline and adolescent substance use, between these factors and subsequent exposure to the adult criminal legal system, and whether these relationships were modified by race or ethnicity.

RESULTS

We found that students reporting substance use had 2.07 (95% CI 1.57, 2.75) times greater odds of reporting subsequent school discipline, and students exposed to school discipline had 1.59 (95% CI 1.26, 2.02) times greater odds of reporting subsequent substance use. Substance use and school discipline were associated with 2.69 (95% CI 2.25, 3.22) and 2.98 (95% CI 2.46, 3.60) times the odds of reporting subsequent adult criminal legal system exposure, respectively. There was little evidence of effect modification by race/ethnicity.

CONCLUSIONS

Findings indicate that school discipline and substance use are reciprocally associated and have direct implications for adolescent health and future criminal legal system exposure.

Collateral consequences of the school-to-prison pipeline: Adolescent substance use and developmental risk

OBJECTIVE

The adolescent health consequences of the school-to-prison pipeline remain underexplored. We test whether initiating components of the school-to-prison pipeline-suspensions, expulsions, and school policing-are associated with higher school-average levels of student substance use, depressed feelings, and developmental risk in the following year.

METHOD

We linked 2003-2014 data from the California Healthy Kids Survey and the Civil Rights Data Collection from over 4,800 schools and 4,950,000 students. With lagged multi-level models, we estimated relationships between the school prevalence of total discipline, out-of-school discipline, and police-involved discipline, and standardized school-average levels of 6 substance use measures and 8 measures of developmental risk, respectively.

RESULTS

The prevalence of school discipline predicted subsequent school-mean substance use and developmental risk. A one-unit higher prevalence of total discipline predicted higher school levels (in standard deviations) of binge drinking alcohol (0.14, 95% CI: 0.11, 0.17), drinking alcohol (0.15, 95% CI: 0.12, 0.18), smoking tobacco (0.09, 95% CI: 0.06, 0.12), using cannabis (0.16, 95% CI: 0.14, 0.19), using other drugs (0.17, 95% CI: 0.14, 0.21), and violence/harassment (0.16, 95% CI: 0.12, 0.2). Total discipline predicted lower levels of reported community support (-0.07, 95% CI: -0.1, -0.05), feeling safe in school (-0.12, 95% CI: -0.16, -0.09), and school support (-0.16, 95% CI: -0.19, -0.12). Associations were greater in magnitude for more severe out-of-school discipline. Findings were inconsistent for police-involved discipline.

CONCLUSION

Exclusionary school discipline and school policing-core elements of the school-to-prison pipeline-are previously unidentified population predictors of adolescent substance use and developmental risk.

Punitive school discipline as a mechanism of structural marginalization with implications for health inequity: A systematic review of quantitative studies in the health and social sciences literature

Punitive school discipline deploys surveillance, exclusion, and corporal punishment to deter or account for perceived student misbehavior. Yet, education and legal scholarship suggests it fails to achieve stated goals and exacerbates harm. Furthermore, it is disproportionately imposed upon Black, Latinx, Native/Indigenous, LGBTQIA, and disabled students, concentrating its harms among marginalized young people. Its implications for health, however, are less clear. Using public health theories of sociostructural embodiment, we propose a framework characterizing pathways linking societal ideologies (e.g., racism) to punitive discipline with implications for health and health inequity and then present our systematic review of the punitive school discipline-health literature (N = 19 studies) conducted in accordance with PRISMA guidelines. Data were extracted on guiding theories, study characteristics, measurement, methods, and findings. This literature links punitive school discipline to greater risk for numerous health outcomes, including persistent depressive symptoms, depression, drug use disorder in adulthood, borderline personality disorder, antisocial behavior, death by suicide, injuries, trichomoniasis, pregnancy in adolescence, tobacco use, and smoking, with documented implications for racial health inequity. Using our adapted framework, we contextualize results and recommend avenues for future research. Our findings support demands to move away from punitive school discipline toward health-affirming interventions to promote school connectedness, safety, and wellbeing.

School Health Predictors of the School-to-Prison Pipeline: Substance Use and Developmental Risk and Resilience Factors

PURPOSE

The purpose of the study is to establish prospective relationships among school mean levels of substance use, developmental risk and resilience factors, and school discipline.

METHODS

We linked 2003-2014 data from the California Healthy Kids Survey and the Civil Rights Data Collection, from more than 4,800 schools and 4,950,000 students. With lagged multilevel linear models, we estimated relationships among standardized school average levels of six substance use measures; eight developmental risk and resilience factors; and the prevalence of total discipline, out-of-school discipline, and police-involved discipline.

RESULTS

School mean substance use and risk/resilience factors predicted subsequent prevalence of discipline. For example, a one-standard deviation higher school mean level of smoking, binge drinking, and cannabis use was associated, respectively, with 16% (95% confidence interval [CI]: 14%, 18%), 18% (95% CI: 16%, 20%), and 21% (95% CI: 19%, 23%) higher subsequent prevalence of total discipline. A one-standard deviation higher mean level of community support and feeling safe in school was associated, respectively, with 21% (95% CI: 18%, 23%) and 9% (95% CI: 7%, 11%) lower total discipline. Higher violence/harassment was associated with 5% (95% CI: 4%, 7%) higher total discipline. Peer and home support, student resilience, and neighborhood safety were not associated with total discipline. Nearly all associations remained, attenuated, when we restricted to out-of-school and police-involved discipline.

CONCLUSIONS

Schools with students who, on average, have higher substance use, less school and community support, and feel less safe in schools have a higher prevalence of school discipline and police contact. The public health implications of mass criminalization extend beyond criminal legal system settings and into schools.

Policing the pandemic: Estimating spatial and racialized inequities in New York City police enforcement of COVID-19 mandates

The use of policing to enforce public health guidelines has historically produced harmful consequences, and early evidence from the police enforcement of COVID-19 mandates suggested Black New Yorkers were disproportionately represented in arrests. The over-policing of Black and low-income neighborhoods during a pandemic risks increased transmission, potentially exacerbating existing health inequities. To assess racialized and class-based inequities in the enforcement of COVID-19 mandates at the ZIP-code-level, we conducted a retrospective spatial analysis of demographic factors and public health policing in New York City from March 12-May 24, 2020. Policing outcomes (COVID-19 criminal court summonses and public health and nuisance arrests) were measured using publicly available police administrative data. After controlling for two measures of social distancing compliance, a standard deviation increase in percentage of Black residents was associated with a 73% increase (95% CI: 35%, 123%) in the COVID-19-specific summons rate and a 34% increase (95% CI: 17%, 53%) in the public health and nuisance arrest rate. Percentage of Black residents and historical stop-and-frisk rates had stronger associations with COVID-19 summons rates than multiple measures of social distancing compliance. Findings demonstrate pronounced spatial and racialized inequities in pandemic policing of public health that mimic historical policing practices deemed racially discriminatory. If the field of public health supports criminalization and punishment as public health strategies, it risks reinscribing racialized health inequities.

Identifying sensitive periods when changes in parenting and peer factors are associated with changes in adolescent alcohol and marijuana use

PURPOSE

There are well-established associations between parental/peer relationships and adolescent substance use, but few longitudinal studies have examined whether adolescents change their substance use in response to changes in their parents' behavior or peer networks. We employ a within-person change approach to address two key questions: Are changes in parenting and peer factors associated with changes in adolescent marijuana and alcohol use? Are there sensitive periods when changes in parenting and peer factors are more strongly associated with changes in adolescent marijuana and alcohol use?

METHODS

We analyzed longitudinal data collected annually on 503 boys, ages 13-19, recruited from Pittsburgh public schools. Questionnaires regarding parental supervision, negative parenting practices, parental stress, physical punishment, peer delinquency, and peer drug use were administered to adolescents and their caretakers. Alcohol and marijuana use were assessed by a substance use scale adapted from the National Youth Survey.

RESULTS

Reductions in parental supervision and increases in peer drug use and peer delinquency were associated with increases in marijuana frequency, alcohol frequency, and alcohol quantity. Increases in parental stress were associated with increases in marijuana and alcohol frequency. The magnitudes of these relationships were strongest at ages 14-15 and systematically decreased across adolescence. These associations were not due to unmeasured stable confounders or measured time-varying confounders.

CONCLUSIONS

Reducing or mitigating changes in parenting and peer risk factors in early adolescence may be particularly important for preventing substance use problems as adolescents transition into young adulthood.

Association between county jail incarceration and cause-specific county mortality in the USA, 1987-2017: a retrospective, longitudinal study

BACKGROUND

Mass incarceration has collateral consequences for community health, which are reflected in county-level health indicators, including county mortality rates. County jail incarceration rates are associated with all-cause mortality rates in the USA. We assessed the causes of death that drive the relationship between county-level jail incarceration and mortality.

METHODS

In this retrospective, longitudinal study, we assessed the association between county-level jail incarceration rates and county-level cause-specific mortality using county jail incarceration data (1987-2017) for 1094 counties in the USA obtained from the Vera Institute of Justice and cause-specific mortality data for individuals younger than 75 years in the total county population (1988-2018) obtained from the US National Vital Statistics System. We fitted quasi-Poisson models for nine common causes of death (cerebrovascular disease, chronic lower respiratory disease, diabetes, heart disease, infectious disease, malignant neoplasm, substance use, suicide, and unintentional injury) with county fixed effects, controlling for all unmeasured stable county characteristics and measured time-varying confounders (county median age, county poverty rate, county percentage of Black residents, county crime rate, county unemployment rate, and state incarceration rate). We lagged county jail incarceration rates by 1 year to assess the short-term, by 5 years to assess the medium-term, and by 10 years to assess the long-term associations of jail incarceration with premature mortality.

FINDINGS

A 1 per 1000 within-county increase in jail incarceration rate was associated with a 6·5% increase in mortality from infectious diseases (risk ratio 1·065, 95% CI 1·061-1·070), a 4·9% increase in mortality from chronic lower respiratory disease (1·049, 1·045-1·052), a 2·6% increase in mortality induced from substance use (1·026, 1·020-1·032), a 2·5% increase in suicide mortality (1·025, 1·020-1·029), and smaller increases in mortality from heart disease (1·021, 1·019-1·023), unintentional injury (1·015, 1·011-1·018), malignant neoplasm (1·014, 1·013-1·016), diabetes (1·013, 1·009-1·018), and cerebrovascular disease (1·010, 1·007-1·013) after 1 year. Associations between jail incarceration and cause-specific mortality rates weakened as time lags increased, but to a greater extent for causes of death with generally shorter latency periods (infectious disease and suicide) than for those with generally longer latency periods (heart disease, malignant neoplasm, and cerebrovascular disease).

INTERPRETATION

Jail incarceration rates are potential drivers of many causes of death in US counties. Jail incarceration can be harmful not only to the health of individuals who are incarcerated, but also to public health more broadly. Our findings suggest important points of intervention, including disinvestment from carceral systems and investment in social and public health services, such as community-based treatment of substance-use disorders.

The association between blighted property remediation and domestic crime by alcohol availability

There is increasing evidence that place-based interventions reduce crime and interpersonal violence in urban settings. However, evidence concerning the impacts of these neighborhood interventions on domestic crime (crime between intimate partners, family, or household members) is inconclusive. We used data from a New Orleans, Louisiana, place-based blighted property remediation intervention to test the hypothesis that the intervention was associated with changes in domestic crime. Because there is evidence that alcohol availability is related to domestic crime, we also assessed whether this association was moderated by alcohol outlet density. We assessed overall associations using a difference-in-difference approach and assessed moderation using a triple-difference approach. The analytic sample consisted of 204 remediated lots and 612 non-remediated matched control lots over 84 months (2011-2017), for a total of 68,544 lot-months. In difference-in-differences analyses, the place-based intervention was associated with additional domestic crime incidence (β = 0.311, 95% CI: 0.016, 0.605; p = 0.039). In triple-difference analyses, on-premise bar density modified this association (β = -0.119, 95%CI: -0.147, -0.092; p < 0.001): in areas with higher bar density, increases in domestic crime were lower near remediated lots compared with control lots. Place-based interventions to reduce blighted properties may have contributed to fewer domestic crime incidents in areas with more bars.

County Jail Incarceration Rates and County Mortality Rates in the United States, 1987-2016

Objectives. To evaluate the relationship between changes in county jail incarceration rates and subsequent county mortality rates across the United States.Methods. We analyzed county jail incarceration rates from the Bureau of Justice Statistics from 1987 to 2016 for 1884 counties and mortality rates from the National Vital Statistics System. We fit 1-year-lagged quasi-Poisson 2-way fixed-effects models, controlling for unmeasured stable county characteristics, and measured time-varying confounders, including county poverty and crime rates.Results. A within-county increase in jail incarceration rates from the first to second quartile was associated with a 2.5% increase in mortality rates, adjusting for confounders (risk ratio [RR] = 1.03; 95% confidence interval [CI] = 1.02, 1.03). This association followed a dose-response relationship and was stronger for mortality among those aged 15 to 34 years (RR = 1.07; 95% CI = 1.06, 1.09).Conclusions. Within-county increases in jail incarceration rates are associated with increases in subsequent mortality rates after adjusting for important confounders.Public Health Implications. Our findings add to the growing body of empirical evidence of the harms of mass incarceration. The criminal justice reform and decarceration movements can use these findings as they develop strategies to end mass incarceration.

Creating Safe And Healthy Neighborhoods With Place-Based Violence Interventions

Violence is a leading cause of death and disability in the United States and abroad, with far-reaching consequences for individuals and communities. Interventions that address environmental and social contexts have the potential for greater populationwide effects, yet research has been slow to identify and rigorously evaluate these types of interventions to reduce violence. Several urban communities across the US are conducting experimental and quasi-experimental community-based research to examine the effect of place-based interventions on violence. Using examples from Philadelphia, Pennsylvania; Flint, Michigan; Youngstown, Ohio; and New Orleans, Louisiana, we describe how place-based interventions that remediate vacant land and abandoned buildings work to reduce violence. These examples support the potential for place-based interventions to create far-reaching and sustainable improvements in the health and safety of communities that experience significant disadvantage. These interventions warrant the attention of community stakeholders, funders, and policy makers.

What is kangaroo mother care? Systematic review of the literature

BACKGROUND

Kangaroo mother care (KMC), often defined as skin-to-skin contact between a mother and her newborn, frequent or exclusive breastfeeding, and early discharge from the hospital has been effective in reducing the risk of mortality among preterm and low birth weight infants. Research studies and program implementation of KMC have used various definitions.

OBJECTIVES

To describe the current definitions of KMC in various settings, analyze the presence or absence of KMC components in each definition, and present a core definition of KMC based on common components that are present in KMC literature.

METHODS

We conducted a systematic review and searched PubMed, Embase, Scopus, Web of Science, and the World Health Organization Regional Databases for studies with key words "kangaroo mother care", "kangaroo care" or "skin to skin care" from 1 January 1960 to 24 April 2014. Two independent reviewers screened articles and abstracted data.

FINDINGS

We screened 1035 articles and reports; 299 contained data on KMC and neonatal outcomes or qualitative information on KMC implementation. Eighty-eight of the studies (29%) did not define KMC. Two hundred and eleven studies (71%) included skin-to-skin contact (SSC) in their KMC definition, 49 (16%) included exclusive or nearly exclusive breastfeeding, 22 (7%) included early discharge criteria, and 36 (12%) included follow-up after discharge. One hundred and sixty-seven studies (56%) described the duration of SSC.

CONCLUSIONS

There exists significant heterogeneity in the definition of KMC. A large number of studies did not report definitions of KMC. Skin-to-skin contact is the core component of KMC, whereas components such as breastfeeding, early discharge, and follow-up care are context specific. To implement KMC effectively development of a global standardized definition of KMC is needed.

Pregnancy Options Counseling and Abortion Referrals Among US Primary Care Physicians: Results From a National Survey

BACKGROUND AND OBJECTIVES

Primary care physicians (PCPs) can play a critical role in addressing unintended pregnancy through high-quality options counseling and referrals.

METHODS

We surveyed a nationally representative sample of 3,000 PCPs in general, family, and internal medicine on practices and opinions related to options counseling for unintended pregnancy. We assessed predictors of physician practices using multivariable logistic regression weighted for sampling design and differential non-response.

RESULTS

Response rate was 29%. Seventy-one percent believed residency training in options counseling should be required, and 69% believed PCPs have an obligation to provide abortion referrals even in the presence of a personal objection to abortion. However, only 26% reported routine options counseling when caring for women with unintended pregnancy compared to 60% who routinely discuss prenatal care. Among physicians who see women seeking abortion, 62% routinely provide referrals, while 14% routinely attempt to dissuade women. Family physicians were more likely to provide routine options counseling when seeing patients with unintended pregnancy than internal medicine physicians (32% vs 21%, P=0.002). In multivariable analyses, factors associated with higher odds of routine abortion referrals were more years in practice (OR=1.03 for each additional year, 95% CI: 1.00-1.05), identifying as a woman vs a man (OR=2.11, 95% CI: 1.31-3.40), practicing in a hospital vs private primary care/multispecialty setting (OR=3.17, 95% CI: 1.10-9.15), and no religious affiliation of practice vs religious affiliation (OR for Catholic affiliation=0.27, 95% CI: 0.11-0.66; OR for other religious affiliation=0.36, 95% CI: 0.15-0.83). Personal Christian religious affiliation among physicians who regularly attend religious services vs no religious affiliation was associated with lower odds of counseling (OR=0.48, 95% CI: 0.26-0.90) and referrals (OR=0.31, 95% CI: 0.15-0.62), and higher odds of abortion dissuasion (OR=4.03, 95% CI: 1.46-11.14).

CONCLUSIONS

Findings reveal the need to support fuller integration of options counseling and abortion referrals in primary care, particularly through institutional and professional society guidelines and training opportunities to impart skills and highlight the professional obligation to provide non-directive information and support to women with unintended pregnancy.

Suicidal ideation in pregnancy: an epidemiologic review

Suicidal behaviors are the leading causes of injury and death worldwide, and are leading causes of maternal deaths in some countries. One of the strongest risk factors, suicidal ideation, is considered a harbinger and distal predictor of later suicide attempt and completion, and also presents an opportunity for interventions prior to physical self-harm. The purpose of this systematic epidemiologic review is to synthesize available research on antepartum suicidal ideation. Original publications were identified through searches of the electronic databases using the search terms pregnancy, pregnant women, suicidal ideation, and pregnan* and suicid* as root searches. We also reviewed references of published articles. We identified a total of 2626 articles through the electronic database search. After irrelevant and redundant articles were excluded, 57 articles were selected. The selected articles were original articles that focused on pregnancy and suicidal ideation. Of the 57 included articles, 20 reported prevalence, 26 reported risk factors, 21 reported consequences of antepartum suicidal ideation, and 5 reported on screening measures. Available evidence indicates that pregnant women are more likely than the general population to endorse suicidal ideation. Additionally, a number of risk factors for antepartum suicidal ideation were identified including intimate partner violence, <12-year education, and major depressive disorder. There is a need for enhanced screening for antepartum suicidal ideation. The few screening instruments that exist are limited as they were primarily developed to measure antepartum and postpartum depression. Given a substantial proportion of women with suicidal ideation that does not meet clinical thresholds of depression and given the stress-diathesis model that shows susceptibility to suicidal behavior independent of depressive disorders, innovative approaches to improve screening and detection of antepartum suicidal ideation are urgently needed.

Kangaroo Mother Care and Neonatal Outcomes: A Meta-analysis

CONTEXT

Kangaroo mother care (KMC) is an intervention aimed at improving outcomes among preterm and low birth weight newborns.

OBJECTIVE

Conduct a systematic review and meta-analysis estimating the association between KMC and neonatal outcomes.

DATA SOURCES

PubMed, Embase, Web of Science, Scopus, African Index Medicus (AIM), Latin American and Caribbean Health Sciences Information System (LILACS), Index Medicus for the Eastern Mediterranean Region (IMEMR), Index Medicus for the South-East Asian Region (IMSEAR), and Western Pacific Region Index Medicus (WPRIM).

STUDY SELECTION

We included randomized trials and observational studies through April 2014 examining the relationship between KMC and neonatal outcomes among infants of any birth weight or gestational age. Studies with <10 participants, lack of a comparison group without KMC, and those not reporting a quantitative association were excluded.

DATA EXTRACTION

Two reviewers extracted data on study design, risk of bias, KMC intervention, neonatal outcomes, relative risk (RR) or mean difference measures.

RESULTS

1035 studies were screened; 124 met inclusion criteria. Among LBW newborns, KMC compared to conventional care was associated with 36% lower mortality(RR 0.64; 95% [CI] 0.46, 0.89). KMC decreased risk of neonatal sepsis (RR 0.53, 95% CI 0.34, 0.83), hypothermia (RR 0.22; 95% CI 0.12, 0.41), hypoglycemia (RR 0.12; 95% CI 0.05, 0.32), and hospital readmission (RR 0.42; 95% CI 0.23, 0.76) and increased exclusive breastfeeding (RR 1.50; 95% CI 1.26, 1.78). Newborns receiving KMC had lower mean respiratory rate and pain measures, and higher oxygen saturation, temperature, and head circumference growth.

LIMITATIONS

Lack of data on KMC limited the ability to assess dose-response.

CONCLUSIONS

Interventions to scale up KMC implementation are warranted.

Childhood abuse is associated with stress-related sleep disturbance and poor sleep quality in pregnancy

OBJECTIVES

Childhood abuse is associated with increased risks of adult psychiatric disorders and physical health conditions. Mounting evidence documents associations of childhood abuse with sleep disturbances in adulthood. However, to date, no study has evaluated associations of childhood abuse and sleep disturbances among pregnant women.

METHODS

This cross-sectional study included 634 pregnant Peruvian women. To collect information regarding socio-demographic characteristics, history of childhood abuse, and complaints of sleep disturbances, face-to-face interviews were conducted with women in early pregnancy. Ford Insomnia Response to Stress Test (FIRST-S) and the Pittsburgh Sleep Quality Index (PSQI-S), translated from English to Spanish, were used to assess stress-related sleep disturbance and sleep quality, respectively. Logistic regression was used to estimate adjusted odds ratios (aOR) and 95% confidence intervals (95% CIs).

RESULTS

Women who experienced any childhood abuse had a 1.65-fold increased odds of stress-related sleep disturbance (aOR = 1.65; 95% CI: 1.15-2.38) and 2.11-fold increased odds of poor sleep quality during early pregnancy (aOR = 2.11; 95% CI: 1.35-3.30) as compared with women who reported no abuse. Women who reported both physical and sexual abuse during childhood were more than twice as likely to suffer from stress-related sleep disturbance (aOR = 2.26; 95% CI: 1.44-3.53) and poor sleep quality (aOR = 2.43; 95% CI: 1.45-4.09) in comparison to women who reported no childhood abuse.

CONCLUSIONS

A history of childhood abuse is associated with increased odds of stress-related sleep disturbance and poor sleep quality during pregnancy. These findings, if replicated, should be used to inform the development of trauma-informed care for such sleep disturbances induced by childhood trauma.

Adverse childhood experiences are associated with adult sleep disorders: a systematic review

Adverse childhood experiences (ACEs) represent substantial threats to public health and affect about 58% of youth in the US. In addition to their acute effects such as injury and physical trauma, ACEs are associated with an increased risk of several negative health outcomes throughout the life course. Emerging evidence suggests that sleep disorders may be one such outcome, but existing studies have not been systematically reviewed and summarized. We conducted a systematic review to summarize the evidence concerning the relationship between ACEs and sleep disorders and disturbances, with a focus on adult women. Original publications were identified through searches of the electronic databases MEDLINE, Embase, and Web of Science using the keywords "childhood," "adversity," "abuse," and "sleep" as well as searches of the reference lists of eligible studies. Studies evaluating ACEs that occurred before 18 years of age and sleep outcomes that were assessed at 18 years or older were adjudicated and included. A total of 30 publications were identified. Of the 30 studies, 28 were retrospective analyses and there was vast heterogeneity in the types of ACEs and sleep outcomes measured. The majority of retrospective studies (N = 25 of 28) documented statistically significant associations between sleep disorders including sleep apnea, narcolepsy, nightmare distress, sleep paralysis, and psychiatric sleep disorders with a history of childhood adversity. In many studies, the strengths of associations increased with the number and severity of adverse experiences. These associations were corroborated by the two prospective studies published to date. Notably, investigators have documented statistically significant associations between family conflict at 7-15 years of age and insomnia at 18 years of age (odds ratio, OR = 1.4; 95% confidence interval, CI = 1.2-1.7) and between childhood sexual abuse and sleep disturbances 10 years later in adult women (β = 0.24, p <0.05). There is a growing scientific body of knowledge suggesting an association between ACEs and multiple sleep disorders in adulthood. The available evidence indicates the need to develop treatment strategies such as trauma-informed care for survivors of abuse who suffer from sleep disorders and disturbances. Further, longitudinal studies among diverse populations are needed to improve the overall understanding of this association and to investigate potential gender and racial/ethnic disparities in the strength of the association.

Sleep duration, vital exhaustion, and odds of spontaneous preterm birth: a case-control study

BACKGROUND

Preterm birth is a leading cause of perinatal morbidity and mortality worldwide, resulting in a pressing need to identify risk factors leading to effective interventions. Limited evidence suggests potential relationships between maternal sleep or vital exhaustion and preterm birth, yet the literature is generally inconclusive.

METHODS

We examined the relationship between maternal sleep duration and vital exhaustion in the first six months of pregnancy and spontaneous (non-medically indicated) preterm birth among 479 Peruvian women who delivered a preterm singleton infant (<37 weeks gestation) and 480 term controls who delivered a singleton infant at term (≥37 weeks gestation). Maternal nightly sleep and reports of vital exhaustion were ascertained through in-person interviews. Spontaneous preterm birth cases were further categorized as those following either spontaneous preterm labor or preterm premature rupture of membranes. In addition, cases were categorized as very (<32 weeks), moderate (32-33 weeks), and late (34- <37 weeks) preterm birth for additional analyses. Logistic regression was used to estimate adjusted odds ratios (aORs) and 95% confidence intervals (CIs).

RESULTS

After adjusting for confounders, we found that short sleep duration (≤6 hours) was significantly associated with preterm birth (aOR = 1.56; 95% CI 1.11-2.19) compared to 7-8 hours of sleep. Vital exhaustion was also associated with increased odds of preterm birth (aOR = 2.41; 95% CI 1.79-3.23) compared to no exhaustion (Ptrend <0.001). These associations remained significant for spontaneous preterm labor and preterm premature rupture of membranes. We also found evidence of joint effects of sleep duration and vital exhaustion on the odds of spontaneous preterm birth.

CONCLUSIONS

The results of this case-control study suggest maternal sleep duration, particularly short sleep duration, and vital exhaustion may be risk factors for spontaneous preterm birth. These findings call for increased clinical attention to maternal sleep and the study of potential intervention strategies to improve sleep in early pregnancy with the aim of decreasing risk of preterm birth.
