Association of Cigarette Smoking With Interpersonal and Self-Directed Violence in a Large Community-Based Sample

Disentangling the effects of self-control and the use of tobacco and cannabis on violence perpetration from childhood to early adulthood

Associations among self-control, substance use (e.g., tobacco and cannabis use), and violence perpetration have been documented during the adolescent years, but the direction of these associations is not well understood. Using five assessments (covering 9 years) from a prospective-longitudinal study, we examined self-control as a precursor and subsequent mechanism of associations between adolescent substance use and physical violence perpetration. Data came from a large, ethnically diverse sample (n = 1,056). Youth reported their self-control at ages 11, 13, 15, 17, and 20; and their tobacco and cannabis use, and physical violence perpetration at ages 13, 15, 17, and 20. Cross-lagged panel analyses examined associations between these constructs over time. More self-control in late childhood and early adolescence was associated with less future tobacco and cannabis use and physical violence perpetration. Tobacco use was partially associated with more physical violence over time; these associations were not mediated by self-control. Tobacco use in early adolescence was associated with future cannabis use; during late adolescence, tobacco and cannabis use were reciprocally associated over time. Cannabis use was not associated with future physical violence perpetration. Early adolescent self-control plays an important role in later substance use and violence perpetration, and tobacco use has unique links with both later cannabis use and violence perpetration. Supporting the capacities for self-control in late childhood and early adolescence and preventing the initiation and use of entry-level substances could play an important role in preventing both substance use and violence perpetration and their many costs to society.

Psychopathic Traits Are Associated with Lifetime History of Nicotine Dependence among Incarcerated Offenders

Background: Individuals scoring high on psychopathy engage in problematic patterns of alcohol and illicit substance use. However, our understanding regarding the association between psychopathy and nicotine use remains limited, which is surprising, given the detrimental consequences associated with such use. Previous studies have observed significant correlations between psychopathic traits (particularly Factor 2 scores assessing lifestyle/behavioral and antisocial traits from the Psychopathy Checklist - Revised [PCL-R]) and increased frequency of nicotine use. However, no study has investigated whether individuals scoring high on psychopathy are characterized by problematic patterns of nicotine use, including lifetime history of nicotine dependence.Objectives: The current study aimed to address this gap, specifically investigating whether PCL-R scores were associated with higher total scores from the Fagerström Test for Nicotine Dependence (FTND).Results: Across both incarcerated men and women, PCL-R total, Factor 2, and Facet 3 (measuring lifestyle/behavioral psychopathic traits) scores were positively correlated with FTND total scores. Additionally, across both samples, hierarchical linear regression analyses revealed these same psychopathy scores remained associated with higher FTND total scores when controlling for additional covariate measures (e.g., age, severity of alcohol and illicit substance use, race, ethnicity, and IQ).Conclusions/Importance: Though associated with small effect sizes, our results support the notion that lifestyle/behavioral psychopathic traits represent a general risk factor for engaging in risky behavior associated with deleterious health consequences, including nicotine use. Our results hold implications for the development of treatment approaches, designed to reduce problematic levels of substance use among individuals scoring high on psychopathy.

Associations of agression and use of caffeine, alcohol and nicotine in healthy and aggressive individuals

BACKGROUND

Caffeine, alcohol, and nicotine are the three most commonly used psychoactive substances in the world. Given the known propensity of these substances to influence behavior, the relationship between these substances and aggressive and impulsive behaviors, in particular is of interest.

METHODS

1062 adult individuals participated in this study including those with Intermittent Explosive Disorder (IED) and non-aggressive healthy (HC) and psychiatric (PC) controls. Data regarding current and life use of caffeine, alcohol, and nicotine were recorded as were responses on measures of aggression, anger, and impulsivity.

RESULTS

Dimensional measures of aggression, anger, and impulsiveness were variably but significantly related to the consumption of these commonly used psychoactive substances. These findings were generally mirrored when using the categorical construct of IED. Finally, these findings were not due to comorbidity with other psychiatric disorders.

CONCLUSIONS

These data confirm a link between these externalizing behaviors and these three legal and commonly consumed psychoactive substances in clinically relevant individuals.

Risk of Injury to Others: The Development of an Algorithm to Identify Children and Youth at High-Risk of Aggressive Behaviours

Youth violence is considered one of the most preventable causes of morbidity and premature mortality. Various risk factors have previously been identified, however, there is presently a crucial need to develop effective decision-support tools in order to identify children and youth at increased risk for violence. The current study utilised data collected from the interRAI Child and Youth Mental Health Screener (ChYMH-S), within the province of Ontario, to develop and validate a methodology for the purpose of identifying young persons who were at greater risk of harm to others. Additional data from 59 mental health agencies validated the algorithm, and it was found to be a strong predictor of harmful behaviour toward others. The RIO algorithm provides a valuable decision-support tool with strong psychometric properties that may be used to identify young persons who exhibit signs or symptoms associated with increased likelihood of harm toward others, in order to provide early intervention efforts for these vulnerable youth, thereby reducing the likelihood of future aggressive behaviours.

Gender differences in the acceptance of wife-beating in Nigeria: evidence from the 2018 Demographic and Health Survey

The world over, more than one-third of women have been victims of either physical or sexual violence, or both, most of which are perpetrated by intimate partners. Intimate partner violence (IPV) has negative consequences for women's health, socio-economic and psychological wellbeing. Similarly, acceptance of IPV has negative implications for its spread, sympathy for victims, and utilisation of antenatal and postnatal healthcare services among women. This study investigates the influence of age, education, location, religion, marriage type, employment, wealth level, extramarital sex, smoking, internet use, media exposure and decision making on the justification of IPV, and how the associations vary between men and women. The study utilised the 2018 Nigeria's Demographic and Health Survey. The data analysed was comprised of 8,018 men and 28,888 women who were married or living with a partner. It was found that women are more likely to accept IPV than men (AOR: 1.627). Educational difference between spouses influences women's experience of and acceptance of IPV. Overall, being young, being uneducated, living in the north, being Muslim, being polygamous, being employed, being poor, having extra-marital sex, being a smoker, not having access to internet, and not being exposed to the media increased the odds of IPV justification. However, while Muslim women had higher odds of accepting IPV than Christians (AOR: 1.587), Muslim men have lower likelihood of IPV justification than Christian men (AOR: 0.759). Gender differences also exist in the influence of age, marriage type, employment, extra-marital sex, smoking, media exposure and decision making. This study underscores the importance of applying differing intervention programmes to men and women where necessary.

Risk factors for inducing violence in patients with delirium

BACKGROUND

Violence in patients with delirium may occur suddenly and unpredictably in a fluctuating state of consciousness. Although various factors are involved, appropriate assessment and early response to factors related to violence in delirium are expected to prevent dangerous and distressing acts of violence against patients, their families and medical staff, and minimize the use of physical restraint and excessive drug sedation.

METHODS

Subjects were 601 delirium cases referred to the department of psychiatry over the course of 5 years at a general hospital. The demographic, clinical, and pharmacological variables of patients with violence (n = 189) were compared with those of patients without violence (n = 412). Logistic regression analysis was applied to determine whether any specific individual factors were associated with violence.

RESULTS

Current smoker status (p < .0005), older age (p < .0005), male gender (p = .004), and use of intensive care units (p = .043) were identified as factors associated with violence in patients with delirium.

CONCLUSIONS

Screening tools for violence in patients with delirium and adequate management may assist in better outcomes for patients and medical staff. Further research should evaluate the usefulness of nicotine replacement treatment for the prevention of violence during nicotine withdrawal, including whether it is safe for elderly inpatients with a high incidence of delirium in clinical practice.

Higher Levels of Nicotine Dependence in Adolescence are Associated with Younger Onset Age of Violent Criminality: A Follow-Up Study of Former Adolescent Psychiatric Inpatients

OBJECTIVE

Earlier studies have reported that smoking is associated with violent behaviour. This study investigated nicotine dependence (ND), defined as already present in adolescence, and its relation to subsequent violent criminal offending.

METHOD

The baseline dataset is composed of 508 former adolescent inpatients, admitted to a psychiatric hospital between the ages of 13-17. Adolescent ND was assessed using the modified Fagerström Tolerance Questionnaire. Follow-up data on crimes up to young adulthood was acquired from the Legal Register Centre of Finland. The study analyzes the participants with violent offences (n = 78) and those without any criminal history (n = 368).

RESULTS

Over 80% of the violent offenders had ND already in adolescences. One third (32.2%) of those with high ND had committed their first violent crime before 18 years of age, the proportions being 15.2% in moderate and 7.1% in no-ND groups. The likelihood for committing first violent crimes at a younger age was increased in the participants with high (adjusted Hazard Ratio (aHR) = 2.66, p = .008) or moderate ND (aHR = 2.40, p = .011).

CONCLUSIONS

Adolescent psychiatric patients, showing moderate to high levels of addiction to nicotine, should be a target population for adolescent focused smoking cessation interventions and programs. Adolescents addicted to nicotine may benefit from intensive clinical attention in order to avoid more adverse and unfavorable outcomes in life, beyond merely physical health related problems.

Risk Factors for Recurrent Injuries from Physical Violence Among African Men in The Gambia

While men are known to be at high risk of recurrent injuries from physical violence, the risk factors in African men have not been investigated. We conducted a matched case-control study to identify factors associated with recurrent injuries from physical violence in The Gambia. Eligible participants were injured male patients aged ≥ 15 years. Over the 12-month study period, 257 cases with recurrent injuries from physical violence, and 257 control patients each from two control groups (violence controls and nonviolence controls) were recruited from eight emergency rooms located in six districts of the Greater Banjul Metropolitan Area, The Gambia. The two control groups matched cases at the same health facility, date of injury, and age, in which violence controls (VCs) experienced only one violence-related injury in the past 12 months and nonviolence controls (NCs) experienced no violence-related injuries. Results of the multivariable conditional logistic regression showed that for both the VC and NC groups, a polygamous family (OR_VC, 3.62; OR_NC, 2.79), > 8 family members (OR_VC, 5.60; OR_NC, 4.81), being brought up by a family relative (OR_VC, 5.17; OR_NC, 2.11), having smoked cigarettes in the past week (OR_VC, 3.53; OR_NC, 4.03), and perceiving no family support (OR_VC, 1.12; OR_NC, 1.19) were significantly associated with the occurrence of recurrent violent injuries. Furthermore, compared to the NCs, three additional factors of > 2 male siblings (OR_NC, 1.84), low household income (OR_NC, 3.11), and alcohol consumption in the past week (OR_NC, 4.66) were significantly associated with the occurrence of recurrent violent injuries. These findings may fill in a knowledge gap that will be beneficial for developing effective intervention programs to reduce recurrent injuries from physical violence among African men.
