Childhood maltreatment and the persistence of smoking: a longitudinal study among adults in the US

Explaining how childhood physical abuse and physical neglect influence adult depression: An analysis with multiple sequential mediators

BACKGROUND

Substantial evidence indicates that experiencing physical abuse and neglect during childhood significantly elevates the likelihood of developing depression in adulthood. Nevertheless, there remains a dearth of understanding regarding the mechanisms underpinning this correlation.

OBJECTIVE

In this study, we aimed to examine the associations of childhood physical abuse and physical neglect with depression using follow-up data from UK Biobank and quantified the contribution of smoking, insomnia, and BMI in these associations.

PARTICIPANTS AND SETTINGS

This study included 144,704 participants (64,168 men and 80,536 women) from UK Biobank, most of whom were white (97 %).

METHODS

Physical abuse and physical neglect were measured using two items of Childhood Trauma Screener (CTS). Data on the incidence of depression were obtained from primary care, hospital inpatient records, self-reported medical conditions, and death registries. We used a sequential mediation analysis based on the "g-formula" approach to explore the individual and joint effects of potential mediators.

RESULTS

The depression incidence rate was 1.85 per 1000 person-years for men and 2.83 per 1000 person-years for women, respectively. Results of Cox proportional risk regression showed that physical abuse (HRs: 1.39-1.53, P < 0.001) and physical neglect (HRs: 1.43-1.60, P < 0.001) are associated with depression. Smoking, insomnia, and BMI together mediated 3 %-26 % of the associations.

CONCLUSIONS

These findings contribute to our understanding of how physical abuse and physical neglect influence depression. Furthermore, a more effective reduction in the burden of depression can be achieved by managing modifiable mediators.

Parental phubbing and mobile phone addiction among Chinese adolescents: a moderated mediation model

It has been reported that parental phubbing is a significant predictor of mobile phone addiction (MPA) among adolescents. However, the mechanisms underlying this association remain largely unclarified. On the basis of the social learning theories and ecological systems, this study assessed the mediating effect of deviant peer affiliation and the moderating effect of sensation seeking in the association between parental phubbing and MPA among Chinese adolescents. A total of 786 Chinese adolescents (mean age = 13.17 years, SD = 1.35) completed the questionnaires anonymously about parental phubbing, MPA, deviant peer affiliation and sensation seeking. After controlling for study variables, deviant peer affiliation could partially mediate the association between parental phubbing and MPA among adolescents and this indirect path could be moderated by sensation seeking. Notably, the effect of deviant peer affiliation on MPA was more pronounced in adolescents with higher sensation seeking than in those with lower sensation seeking.

Tobacco use, trauma exposure and PTSD: a systematic review

Tobacco use remains one of the most significant preventable public health problems globally and is increasingly concentrated among vulnerable groups, including those with trauma exposure or diagnosed with PTSD. The goal of this systematic review was to update and extend previous reviews. Of the 7224 publications that met the initial criteria, 267 were included in the review. Summary topic areas include conceptual frameworks for the relation between trauma or PTSD and tobacco use; associations between trauma exposure or PTSD and tobacco use; number and type of trauma exposures and tobacco use; PTSD symptoms and tobacco use; Treatment-related studies; and the examination of causal relations. Evidence continues to indicate that individuals exposed to trauma or diagnosed with PTSD are more likely to use tobacco products, more nicotine dependent and less likely to abstain from tobacco even when provided evidence-based treatments than individuals without trauma. The most commonly cited causal association proposed was use of tobacco for self-regulation of negative affect associated with trauma. A small proportion of the studies addressed causality and mechanisms of action. Future work should incorporate methodological approaches and measures from which we can draw causal conclusions and mechanisms to support the development of viable therapeutic targets.

Association between adverse childhood experiences and self-reported health-risk behaviors among cancer survivors: A population-based study

AIMS

Existing evidence shows that people who report Adverse Childhood Experiences (ACEs) are more likely to exhibit health-risk behaviors. However, limited research on this topic pertains to oncology population. We aim to address this knowledge gap by estimating the prevalence of ACEs and investigating their association with self-reported health-risk behaviors among adult cancer survivors living in the U.S.

METHODS

We conducted a secondary analysis using cross-sectional data from the 2021 Behavioral Risk Factor Surveillance System ACE module. We included 4,126 adults, aged ≥18 years, with a history of cancer. The outcome variable was self-reported health-risk behaviors, which included cigarette smoking, e-cigarette use, and binge alcohol drinking. Self-reported ACEs history was the primary independent variable, comprised of 11 questions regarding child abuse and dysfunctional households. We conducted descriptive statistics and multivariable logistic regression to describe the relationship between the ACE history and health-risk behaviors.

RESULTS

Overall, 84.2% of cancer survivors self-reported as White, 58.4% were women, and 76.6% were aged 65+ years. Nearly two-thirds of the sample (63.2%) self-reported at least one ACE (prior to age 18) and 21.7% engaged in ≥1 health-risk-behaviors, such as cigarette smoking, binge alcohol drinking, or e-cigarette use. Experiencing ≥3 ACEs was associated with 145% increased odds of reporting at least one health-risk behavior (OR = 2.45, 95% CI [1.78-3.38]) when compared to those without a history of ACEs. Besides, survivors who were younger, divorced, less educated, and had low income had higher odds of reporting at least one health-risk behavior.

CONCLUSIONS

Overall, a history of ACEs is associated with health-risk behaviors. These all can negatively impact cancer survivors' overall well-being. Early screening for ACE during oncologic visits can be a protective measure for preventing health-risk behaviors among cancer survivors.

Tobacco smoking related to childhood trauma mediated by cognitive control and impulsiveness in severe mental disorders

BACKGROUND

People with severe mental disorders (SMDs) show an increased prevalence of tobacco smoking compared to the general population. Tobacco smoking and other adult adverse health behaviors have been associated with traumatic experiences in childhood. In the present study we investigated the relationship between childhood trauma and tobacco smoking in people with SMDs, including the possible mediating role of cognitive- and personality characteristics, i.e. cognitive control, impulsiveness, affective lability and self-esteem.

METHODS

Enrolled in the study were 871 participants with schizophrenia (SCZ, N = 484) and bipolar (BD, N = 387) spectrum disorders. We assessed tobacco smoking behavior (yes/no and amount), and history of childhood trauma with the Childhood Trauma Questionnaire. Data on cognitive control, impulsiveness, affective lability, and self-esteem were available in subsamples. We performed linear and logistic regressions, and conducted mediation analyses in PROCESS. All analyses were as standard adjusted for age, sex, and diagnostic group.

RESULTS

Experience of one or more subtypes of childhood trauma was significantly associated with smoking tobacco in SMDs (p = 0.002). There were no significant associations between childhood trauma and amount of tobacco smoking. Cognitive control and impulsiveness were significant mediators between childhood trauma and tobacco smoking.

CONCLUSIONS

These findings indicate the experience of childhood trauma as a predisposing factor for tobacco smoking in SMDs. Cognitive control and impulsiveness were suggested as mediating mechanisms, indicating the importance of considering inhibition related self-regulatory aspects in efforts to improve health behavior in individuals with SMDs and childhood trauma.

The association between child maltreatment and health risk behaviours and conditions throughout life in the Australian Child Maltreatment Study

OBJECTIVE

To estimate associations between all five types of child maltreatment (emotional abuse, neglect, physical abuse, sexual abuse, and exposure to domestic violence) and health risk behaviours and conditions.

DESIGN, SETTING, PARTICIPANTS

Nationally representative survey of Australian residents aged 16 years and older conducted by computer-assisted telephone interviewing.

MAIN OUTCOME MEASURES

Associations between child maltreatment and the following health risk behaviours and conditions: current smoker, binge drinking (at least weekly in past 12 months), cannabis dependence (according to the Cannabis Severity of Dependence Scale), obesity (based on body mass index), self-harm in past 12 months, and suicide attempt in past 12 months.

RESULTS

A total of 8503 participants completed the survey. All five types of child maltreatment were associated with increased rates of all of the health risk behaviours and conditions that we considered. The strongest associations were in the youngest age group (16-24-year-olds). Sexual abuse and emotional abuse were associated with the highest odds of health risk behaviours and conditions. Cannabis dependence, self-harm and suicide attempts were most strongly associated with child maltreatment. Experiencing more than one type of child maltreatment was associated with higher rates of health risk behaviours and conditions than experiencing one type of child maltreatment.

CONCLUSIONS

Child maltreatment is associated with substantially increased rates of health risk behaviours and conditions. Prevention and intervention efforts should be informed by trauma histories, and holistic psychosocial care should be incorporated into programs focusing on behaviour change.

Association between childhood maltreatment and adult cortisol concentrations mediated through subjective health complaints

Background

Lower cortisol concentrations in adulthood were repeatedly associated with more severe childhood maltreatment. Additionally, childhood maltreatment was reported to promote health risk behavior, such as smoking or alcohol consumption, and to increase the risk of mental and somatic diseases during adulthood, such as major depressive disorders or obesity. The present study investigated if health risk behavior and disease symptoms in adults mediate the associations between past childhood maltreatment and present basal serum cortisol concentrations.

Methods

Data from two independent adult cohorts of the general population-based Study of Health in Pomerania (SHIP-TREND-0: N = 3,517; SHIP-START-2: N = 1,640) was used. Childhood maltreatment was assessed via the Childhood Trauma Questionnaire (CTQ). Cortisol concentrations were measured in single-point serum samples. Health risk behavior and mental and physical symptoms were used as mediators. Mediation analyses were calculated separately for both cohorts; results were integrated via meta-analyses.

Results

In mediator-separated analyses, associations between childhood maltreatment and basal serum cortisol concentrations were partly mediated by depressive symptoms (BDI-II: βindirect effect = -.011, pFDR = .017, 21.0% mediated) and subjective somatic health complaints (somatic complaints: βindirect effect = -.010, pFDR = .005, 19.4% mediated). In the second step, both mediators were simultaneously integrated into one mediation model. The model replicated the mediation effects of the subjective somatic health complaints (whole model: βindirect effect = -.014, p = .001, 27.6% mediated; BDI-II: βindirect effect = -.006, p = .163, 11.4% mediated, somatic complaints: βindirect effect = -.020, p = .020, 15.5% mediated).

Conclusion

The results support the hypothesis that the long-lasting effects of childhood maltreatment on the stress response system are partly mediated through self-perceived disease symptoms. However, no mediation was found for health risk behavior or physically measured mediators. Mediation models with multiple simultaneous mediators pointed to a relevant overlap between the potential mediators. This overlap should be focused on in future studies.

Child maltreatment and substances use throughout adolescence and adulthood: Data from a Brazilian Birth Cohort

BACKGROUND

Child maltreatment has been associated with substance use later in life, but few studies have used repeated measures.

OBJECTIVE

To assess the association between child maltreatment and use of psychoactive substances from adolescence to early adulthood, and whether this differs by sex.

PARTICIPANTS AND SETTING

3641 participants from the 1993 Pelotas Birth Cohort, Brazil.

METHODS

Child maltreatment (psychological, physical and sexual abuse, and physical neglect) was assessed up to age 15 and use of psychoactive substances (smoking, harmful use of alcohol and use of illicit drugs) was assessed at ages 15, 18, and 22 years. Associations between child maltreatment and use of substances at each time point were analyzed using logistic regression, adjusted for confounders.

RESULTS

Overall, child maltreatment was associated with substance use, and the strength of the associations decreased over time. E.g., the association between psychological abuse and harmful use of alcohol was OR 2.17 (95%CI 1.80, 2.62; p-value < 0.001) at 15 years, OR 1.61 (95%CI 1.31, 1.97; p-value < 0.001) at 18 years, and OR1.55 (95%CI 1.22, 1.96; p-value < 0.001) at 22 years. When sex differences were evident, stronger associations were observed among females. E.g., the association between physical abuse and smoking at 15 years was OR 3.49 (95%CI 2.17, 5.62) in females and OR 0.87 (95%CI 0.30, 2.52) in males (p-value for sex interaction = 0.041).

CONCLUSIONS

Child maltreatment was associated with psychoactive substance in adolescence and early adulthood. Strategies to prevent use of substances could benefit those who suffered maltreatment in childhood.

The Interplay between Child Maltreatment and Stressful Life Events during Adulthood and Cardiovascular Problems-A Representative Study

Psychological stress is a major risk factor for cardiovascular diseases. While the relevance of early life stress, such as that which is due to child maltreatment (CM), is well known to impact individual stress responses in the long-term, and data on the interplay between CM and stressful events in adulthood on cardiovascular health are sparse. Here, we aimed to assess how stressful life events in adulthood are associated with cardiovascular health infarction in later life and whether this association is independent of CM. In a cross-sectional design, a probability sample of the German population above the age of 14 was drawn using different sampling steps. The final sample included 2510 persons (53.3% women, mean age: 48.4 years). Participants were asked about sociodemographic factors, adult life events, CM, and health conditions in adulthood. Results indicate that the number of experienced adverse life events in adulthood is associated with significantly increased odds for obesity (Odds Ration (OR)women = 1.6 [1.3; 2.0], ORmen = 1.4 [1.1; 1.9]), diabetes (ORwomen = 1.5 [1.1; 2.1], ORmen = 1.5 [1.1; 2.3]) and myocardial infarction (ORwomen = 2.1 [1.0; 4.3], ORmen = 1.8 [1.1; 2.8]). This association is not moderated by the experience of CM, which is associated with cardiovascular problems independently. Taken together, adult stressful life events and CM are significantly and independently associated with cardiovascular health in men and women in the German population in a dose-dependent manner. General practitioners, cardiologists and health policy-makers should be aware of this association between psychosocial stressors during childhood and adulthood and cardiovascular health.

A Comparison of the Smoking Outcomes of Self-reported and Agency-Notified Child Abuse in a Population-Based Birth Cohort at 30-Year-Old Follow-up

INTRODUCTION

Retrospective studies show a strong association between self-reported child abuse and subsequent tobacco use. Prospective studies using reports to statutory agencies are less common with limited information on people in their 30s. In addition, there have been no comparisons of the effect of self- and agency-reported abuse on smoking. We therefore assessed the effect on the prevalence and persistence of smoking at the 30-year-old follow-up of prospective agency notifications of child abuse compared to retrospective self-reports of maltreatment in the same birth cohort.

METHODS

There were 2443 young adults with data on smoking and child abuse at 30-year-old follow-up. Information on self-reported abuse was collected using the Child Trauma Questionnaire (CTQ) and linked to notifications of child maltreatment to statutory agencies.

RESULTS

The prevalence of self- and agency-reported maltreatment was 600 (24.7%) and 142 (5.8%), respectively. At follow-up, 565 participants smoked (23.1%) but only 91 (3.8%) smoked 20 or more cigarettes a day. Of the 206 participants who smoked at 14 years, 101 were still smoking at follow-up. On adjusted analyses, both self- and agency-reported maltreatment showed a significant association with the prevalence and persistence of smoking from 14 years old. However, associations were weaker for some of the agency-notified child maltreatment subtypes possibly because of lower numbers.

CONCLUSIONS

Child maltreatment is associated with both an increased prevalence and persistence of smoking at 30-year-old follow-up irrespective of reporting source. This is despite self- and agency-reported maltreatment possibly representing different populations. Smoking cessation programs should therefore target both groups.

IMPLICATIONS

Retrospective studies show an association between self-reported child abuse and subsequent tobacco use. Prospective studies of reports to statutory agencies are less common with limited information on people in their 30s. In addition, there have been no comparisons of self- and agency-reported abuse on smoking outcomes even though they may represent different populations. We therefore compared the effect of both on smoking outcomes at 30-year-old follow-up of 2443 adults from the same birth cohort. On adjusted analyses, both self- and agency-reported maltreatment showed significant associations with the prevalence and persistence of smoking. Smoking prevention and cessation programs should therefore target both groups.

Violence against children and adolescents by nursing staff: prevalence rates and implications for practice

BACKGROUND

International studies show that child maltreatment is a widespread but often underestimated problem that causes high individual, social and economic costs. Child maltreatment is an important topic for the medical sector as well. On the one hand, affected persons often seek support and help from healthcare professionals, but on the other hand, assaults can also occur in medical institutions by healthcare professionals. Surprisingly, there is hardly any data on the frequency of child maltreatment by healthcare professionals in general and particularly by nursing staff.

METHODS

Therefore, in a large representative survey of the German population of 2,516 subjects aged between 14 and 91, the experience of child maltreatment in medical institutions by nursing staff was assessed retrospectively.

RESULTS

Of the 46 subjects who had an inpatient stay in a child and adolescent psychiatry before the age of 18, 33.3% reported to have experienced maltreatment by nursing staff, while 17.3% of the 474 persons who had an inpatient stay in general or pediatric hospitals experienced maltreatment by nursing staff. All forms of maltreatment were significantly more frequent in psychiatric compared to general and pediatric hospitals.

CONCLUSIONS

The results of our representative retrospective survey demonstrate that maltreatment by nursing staff are not rare individual cases, but that medical facilities bear systemic risks for assault. Therefore, it is necessary that all medical institutions, in particular psychiatric hospitals, address this issue. In order to reduce the risk for assaults, it is important not only to implement structural measures but also to develop an attitude that emphasizes zero tolerance for violence against children and adolescents.

History of child maltreatment and excessive dietary and screen time behaviors in young adults: Results from a nationally representative study

Child maltreatment is common and has been associated with substance use addictions, yet few studies have examined associations with potentially addictive dietary and screen time behaviors. The goal of this study was to assess associations between retrospectively self-reported child maltreatment (sexual abuse, physical abuse, emotional abuse, and neglect) and excessive self-reported dietary (sugar sweetened beverage and fast food consumption) and screen time behaviors (television/video watching and leisure time computer use) in early adulthood, overall and by sex and race/ethnicity. Associations were examined using data from 10,813 participants 24-32 years old from the National Longitudinal Study of Adolescent to Adult Health. We used predicted marginal proportions accounting for the complex sample design to obtain prevalence ratios (PRs) and adjusted for demographic characteristics and physical activity. In females, exposure to poly-maltreatment (2+ types of child maltreatment) was associated with excessive sugar sweetened beverage consumption, television/video watching, and leisure time computer use; in males, exposure to poly-maltreatment was associated with excessive sugar sweetened beverage consumption, television/video watching, and fast food consumption. Some associations were particularly strong in racial/ethnic minorities, especially Latina females (poly-maltreatment-sugar sweetened beverage association: aPR = 6.14, 95% CI:2.12, 17.75; poly-maltreatment-computer use association: aPR = 3.08, 95% CI:1.44, 6.58). These findings show that child maltreatment is associated with excessive dietary and screen time behaviors into adulthood, and these associations are present in racial/ethnic groups at high risk of cardiometabolic disease. Extension of an addiction paradigm to include dietary and screen time behaviors may inform health risks and disease prevention efforts in child maltreatment survivors.

Trauma exposure, PTSD symptoms, and tobacco use: Does church attendance buffer negative effects?

Traumatic stress and posttraumatic stress disorder (PTSD) are overrepresented in urban African American communities, and associated with health risk behaviors such as tobacco use. Support and resources provided by churches may reduce trauma-related health risks. In the current study, we assessed weekly church attendance as a moderator of relations between (a) traumatic event exposure and probable PTSD, and (b) probable PTSD and tobacco use. Data were drawn from a health surveillance study conducted in seven churches located in Chicago's West Side. Participants (N = 1015) were adults from churches as well as the surrounding community. Trauma exposure was reported by 62% of participants, with 25% of those who experienced trauma reporting probable PTSD. Overall, more than one-third of participants (37.2%) reported current tobacco use. As compared with non-weekly church attendance, weekly church attendance was associated with a lower likelihood of PTSD (odds ratio [OR] = 0.41; 95% confidence interval [CI] = 0.26-0.62; p < .0001) and lower tobacco use overall (OR = 0.22; 95% CI = 0.16-0.30; p < .0001), but did not moderate the effect of trauma exposure on risk of PTSD, or the effect of PTSD on tobacco use. Findings support church attendance as a potential buffer of trauma-related stress.

Child Maltreatment and Persistent Smoking From Adolescence Into Adulthood: A Birth Cohort Study

OBJECTIVE

A prospective record-linkage analysis to examine whether notified and/or substantiated child maltreatment is associated with the prevalence and persistence of smoking in early adulthood.

METHODS

The sample consisted of 3758 participants enrolled in a population-based birth cohort study in Brisbane, Australia, who were followed up at both 14 and 21 years of age. Suspected experience of child maltreatment was measured by linkage with state child protection agency data. The two main outcomes were the prevalence and persistence of smoking at 21-year follow-up, as well as the 12-month prevalence of nicotine use disorder for participants who completed the Composite International Diagnostic Interview-Auto version.

RESULTS

Of the 3758 young people at the 21-year follow-up, 7.5% (n = 282) had a history of notified maltreatment by the age of 16 years. Of these, 167 cases were substantiated. There were 1362 (35.3%) smokers at 21-year follow-up, although only 220 (5.9%) smoked more than 20 cigarettes daily. Of the 602 participants who smoked at 14 years, 289 were still smoking 7 years later. On adjusted analyses, participants who had experienced any form of notified and/or substantiated maltreatment were approximately twice as likely to be smokers at 21 years old and persistent smokers from 14 years of age. Any form of maltreatment, except sexual abuse, was also associated with an increase in the 12-month prevalence of nicotine use disorders.

CONCLUSIONS

Child maltreatment is associated with both an increased onset and persistence of smoking from adolescence into young adulthood. This may have implications for smoking cessation programs and early interventions for individuals who have experienced maltreatment.

The Type and Timing of Child Maltreatment as Predictors of Adolescent Cigarette Smoking Trajectories

Background: There is limited research examining the association between child maltreatment and cigarette smoking as a specific type of adolescent substance use, and research examining high-risk samples and variations based on maltreatment type and timing remain sparse. Objectives: The primary aim of the study was to examine the relationship between child maltreatment and cigarette smoking trajectories. Methods: Latent class growth analysis and multinomial logistic regression were performed on 903 youth drawn from the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN). Results: Three distinct classes of cigarette smoking trajectories were identified: (1) Stable no/low cigarette use (61%); (2) Gradually increasing cigarette use (30%); and (3) Sharply increasing cigarette use (9%). Physical abuse during early childhood and adolescence predicted membership in the sharply increasing cigarette use class. Neglect during early childhood predicted membership in the gradually increasing cigarette use class. Conclusions: Findings suggest that interventions for adolescent cigarette smoking should integrate trauma-informed approaches. Further, the results highlight early childhood and adolescence as particularly vulnerable periods with respect to the influence of physical abuse and neglect on cigarette smoking, pointing to the need for additional maltreatment prevention efforts during these developmental stages.

Associations between child maltreatment, cigarette smoking, and nicotine dependence in young adults with a history of regular smoking

PURPOSE

The purpose of this study was to evaluate whether childhood maltreatment is associated with smoking behaviors and lifetime nicotine dependence and if associations are moderated by sex. We examined these associations among individuals who ever reported being regular smokers.

METHODS

Using data from the National Longitudinal Study of Adolescent to Adult Health, we examined relationships between retrospectively self-reported child maltreatment (parent/caregiver-perpetrated emotional, physical, sexual abuse, and neglect; and non-parent/caregiver-perpetrated sexual abuse) and self-reported smoking behaviors among individuals with a history of regular smoking. Outcomes were any current smoking in early adulthood (mean age = 28 years), current smoking in adolescent study waves only, adulthood only, and adolescence and adulthood (n = 3581); and lifetime history of nicotine dependence (n = 3594) per the Fagerstrom scale.

RESULTS

Poly-maltreatment (aRR for 2+ vs. 0 exposures = 1.20, 95% CI: 1.08, 1.34) was associated with lifetime nicotine dependence; associations between nicotine dependence and neglect and non-parent/caregiver sexual abuse by force were only present in women. Neglect and non-parent/caregiver sexual abuse by nonphysical threat were associated with continued smoking, and an association between non-parent/caregiver sexual abuse by physical force and continued smoking was also noted in women only. Women who experienced poly-maltreatment were less likely to report current smoking in adolescence but not adulthood.

CONCLUSIONS

These data suggest in a nationally representative sample of ever regular smokers, child maltreatment is associated with outcomes that suggest an inability to quit smoking and some associations may vary by sex.

Association between child maltreatment and central sensitivity syndromes: a systematic review protocol

INTRODUCTION

A growing body of evidence is identifying the link between a history of child maltreatment and a variety of adverse health outcomes ultimately leading to significant social and healthcare burden. Initial work has identified a potential association between child maltreatment and the development of a selection of somatic and visceral central sensitivity syndromes: fibromyalgia, chronic fatigue syndrome, temporomandibular joint disorder, chronic lower back pain, chronic neck pain, chronic pelvic pain, interstitial cystitis, vulvodynia, chronic prostatitis, tension-type headache, migraine, myofascial pain syndrome, irritable bowel syndrome and restless legs syndrome.

METHODS AND ANALYSIS

Primary electronic searches will be performed in the Embase, MEDLINE, PubMed, Scopus, PyscINFO, CINAHL and Cochrane Library databases and a number of Grey Literature sources including child protection and paediatric conference proceedings. Following independent screening of studies by two review authors, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses template will be used to aid extraction. A meta-analysis will be conducted on the included case-control and cohort studies. The Newcastle-Ottawa grading system will be used to assess the quality of included studies. Results will be expressed as pooled ORs for binary data and mean differences for continuous data.

ETHICS AND DISSEMINATION

Ethics approval will not be required. The final results of the review and meta-analysis will be submitted for peer-review publication and also disseminated at relevant conference presentations.

Conscientiousness explains the link between childhood neglect and cigarette smoking in adults from a low-income, urban area-the differential effects of sex

Cigarette smoking represents the leading cause of preventable morbidity and mortality in the US and understanding its risk factors remains a critical public health endeavor. Low-income individuals and individuals with a history of childhood maltreatment are at heightened risk for cigarette smoking, yet the underlying factors between this association are understudied. Conscientiousness is one construct with potential explanatory relevance to both smoking and childhood neglect. The current investigation examined the association between childhood physical and emotional neglect with smoking (i.e., self-reported cigarette smoking and breath carbon monoxide levels) via conscientiousness. The sample was comprised of 115 adults (M_age = 50.46, SD_age = 5.86; 76.4% Black) recruited from a community center serving low-income and homeless individuals. Mediation analyses showed the indirect effect of childhood emotional neglect on cigarette smoking through conscientiousness; for physical neglect, this relationship was only present among males. The current study provides preliminary evidence that conscientiousness may be a particularly important vulnerability factor when examining the association between childhood neglect and smoking.

Adverse Childhood Experiences and the Presence of Cancer Risk Factors in Adulthood: A Scoping Review of the Literature From 2005 to 2015

Exposure to Adverse Childhood Experiences (ACEs) is associated with a host of harmful outcomes, including increased risk for cancer. A scoping review was conducted to gain a better understanding of how ACEs have been studied in association with risk factors for cancer. This review includes 155 quantitative, peer-reviewed articles published between 2005 and 2015 that examined associations between ACEs and modifiable cancer risk factors, including alcohol, environmental carcinogens, chronic inflammation, sex hormones, immunosuppression, infectious agents, obesity, radiation, ultraviolet (UV) radiation, and tobacco, among U.S. adults. This review highlights the growing body of research connecting ACEs to cancer risk factors, particularly alcohol, obesity, and tobacco. Fewer studies investigated the links between ACEs and chronic inflammation or infectious agents. No included publications investigated associations between ACEs and environmental carcinogens, hormones, immunosuppression, radiation, or ultraviolet radiation. Mitigating the impact of ACEs may provide innovative ways to effect comprehensive, upstream cancer prevention.

Early life adversity and health-risk behaviors: proposed psychological and neural mechanisms

Early life adversity (ELA) is associated with poorer health in adulthood, an association explained, at least in part, by increased engagement in health-risk behaviors (HRBs). In this review, we make the case that ELA influences brain development in ways that increase the likelihood of engaging in HRBs. We argue that ELA alters neural circuitry underpinning cognitive control as well as emotional processing, including networks involved in processing threat and reward. These neural changes are associated psychologically and behaviorally with heightened emotional reactivity, blunted reward responsivity, poorer emotion regulation, and greater delay discounting. We then demonstrate that these adaptations to ELA are associated with an increased risk of smoking cigarettes, drinking alcohol, and eating high-fat, high-sugar foods. Furthermore, we explore how HRBs affect the brain in ways that reinforce addiction and further explain clustering of HRBs.

Association of child maltreatment subtypes and long-term physical health in a German representative sample

Background: Child maltreatment is a major public problem, associated with enormous consequences on the individual and socioeconomic level. Studies show a clear impact of child maltreatment on long-term physical health. However, there is a lack of analyses comprising a wide variety of subtypes of maltreatment and addressing cumulative effects of different maltreatment subtypes experienced during childhood on physical health. Objective: The objective of this analysis was to assess the association of different subtypes and the intensity of child maltreatment with long-term physical health outcomes. Methods: In a cross-sectional observational approach, a representative sample of the German population (N=2510) was assessed regarding socioeconomic information, their current health status, and their experiences of child maltreatment using the Childhood Trauma Questionnaire (CTQ). Chi²-Tests were performed to compare differences of physical health conditions in adulthood in association with child maltreatment and binary regression analyses to assess the relationship of physical health and number of different subtypes of maltreatment experienced during childhood. Results: Odds increased significantly for obesity (1.8), diabetes (1.26), cancer (1.28), hypertension (1.16), chronic obstructive pulmonary disease (1.51), history of myocardial infarction (1.29) and stroke (1.31) with increasingenhancing number of experienced subtypes of child maltreatment. Growing intensity of each subtype of maltreatment was associated with higher rates of all assessed physical health conditions, which could point towards a dose-dependency of the relationship between maltreatment and long-term physical health. Conclusions: Child maltreatment is associated with increased odds for the leading morbidity and mortality causes in Germany. Interventions encompassing secondary and primary preventive strategies are critical to target this major public health problem and its devastating consequences.

Physical and mental health burden in cases of bipolar disorder classified as current, former, or non-tobacco smokers

BACKGROUND

Tobacco smoking increases the global burden of bipolar disorder (BD). We examined markers of physical and mental health that are associated with tobacco smoking, controlling for confounders that have not always been considered in previous studies of BD.

METHODS

Over 600 individuals with BD I or II referred to the French Network for bipolar disorder (FACE-BD) who completed standardized assessments, and could be reliably classified as current (CS) or former smokers (FS), were compared with those who were never smokers (NS) on: BD symptom load and psychiatric comorbidities; prevalence of alcohol and substance use disorders (ASUD); medication usage; functioning and physical health parameters. The bivariate and multivariate analyses took into account age and gender.

RESULTS

300 cases (49%) were CS, 78 (13%) FS and 238 (39%) had never smoked. Rates were similar across genders regardless of BD subtype. Compared with NS, CS were more likely to have an ASUD (Odds Ratio (OR) 5.18), BD I (OR 2.09), and lower abdominal obesity (OR 0.97), and FS were more likely to have an ASUD (OR 6.32) and higher abdominal obesity (OR 1.03).

LIMITATIONS

The sample comprised of white Europeans; the FS subgroup was relatively small and we did not apply any statistical correction for the bivariate analyses.

CONCLUSIONS

The increased risk of physical and mental health burden in CS and FS compared to NS represents avoidable morbidity in BD. This study offers support to the argument that individuals with BD should be routinely offered support to prevent or stop tobacco smoking.

Life adversity is associated with smoking relapse after a quit attempt

Multiple cross-sectional studies have linked adverse childhood events and adult adversities to current smoking, lifetime smoking, and former smoking. To date, however, there have been no direct observational studies assessing the influence of adversities on smoking relapse. We prospectively followed 123 participants, 86 of whom were habitual smokers, from pre-quit ad libitum smoking to four weeks post-quit. Thirty-seven non-smokers were also tested in parallel as a comparison group. Subjects provided biological samples for confirmation of abstinence status and self-report history of adversities such as abuse, neglect, family dysfunction, incarceration, and child-parent separation. They also completed mood and smoking withdrawal symptom measures. The results indicated that within non-smokers and smokers who relapsed within the first month of a quit attempt, but not abstainers, females had significantly higher adversity scores than males. Cigarette craving, which was independent from depressive affect, increased for low adversity participants, but not those with no adversity nor high adversity. These results demonstrate that sex and relapse status interact to predict adversity and that craving for nicotine may be an important additional mediator of relapse. These results add further support to the previous cross-sectional evidence of an adversity and smoking relationship. Further studies to clarify how adversity complicates smoking cessation and impacts smoking behaviors are warranted.

Examining the independent protective effect of subjective well-being on severe psychological distress among Canadian adults with a history of child maltreatment

The purpose of this study was to examine the independent protective effect of subjective well-being on severe psychological distress among adult Canadians with a history of child maltreatment. Data for this study were obtained from the 2012 Canadian Community Health Survey-Mental Health (CCHS-MH). A sample of 8126 respondents aged 20-69 years old who experienced at least one child maltreatment event was analyzed using binary logistic regression with severe psychological distress as the outcome variable. Of the 8126 respondents with a history of child maltreatment, 3.9% experienced severe psychological distress within the past month. Results from the multivariate logistic regression revealed that emotional and psychological well-being each had a significant effect on severe psychological distress. For each unit increase in emotional well-being, the odds of a respondent having severe psychological distress were predicted to decrease by a factor of 28% and for each unit increase in psychological well-being, the odds of a respondent having severe psychological distress were predicted to decrease by a factor of 10%, net the effect of demographic, socioeconomic, and health factors. Other factors associated with psychological distress included: younger age, poor self-perceived physical health, and chronic condition. Having post-secondary education, having a higher income, and being non-White predicted lower odds of severe psychological distress. Although, child maltreatment is associated with stressful life events later in adulthood, subjective well-being could serve as a protective factor against severe psychological distress among adults who experienced maltreatment when they were children.

Child maltreatment and pediatric asthma: a review of the literature

BACKGROUND

Child maltreatment is a common problem with known adverse consequences, yet its contributions to the development and course of pediatric asthma are only poorly understood.

MAIN

This review first describes possible pathways connecting child maltreatment to pediatric asthma, including aspects of the physical home environment, health behaviors and disease management, and psychological consequences of child maltreatment. We subsequently review existing studies, which generally report an association between maltreatment experiences and asthma outcomes in childhood. However, this literature is in its early stages; there are only a handful studies, most of them rely on self-reports of both child maltreatment and asthma history, and none have investigated the physiological underpinnings of this association. Taken together, however, the studies are suggestive of child maltreatment playing a role in pediatric asthma incidence and expression that should be explored further.

CONCLUSION

Existing data are sparse and do not allow for specific conclusions. However, the data are suggestive of child maltreatment influencing asthma risk and morbidity long before the adult years. Future research should focus on understanding how child maltreatment contributes to asthma disease risk and progression in this highly vulnerable population.
