Tobacco smoking and mental disorders in Australian adolescents

Interaction between nutrition-related parameters and sexual orientation on depression

OBJECTIVES

Sexual minorities may be more vulnerable to mental disorders. Previous studies have found associations between diet and depression, but no studies have focused on the interaction between nutrition-related parameters and sexual orientation regarding depression. This study aims to explore the interaction between nutrition-related parameters and sexual orientation regarding depression.

STUDY DESIGN

Cross-sectional analysis using NHANES 2007-2016 data.

METHODS

This study utilized data from NHANES 2007-2016, with 11,065 participants involved. Nutrition-related parameters were evaluated using the healthy eating index-2015 (HEI-2015) and the dietary inflammation index (DII), while depression was obtained through Patient Health Questionnaire (PHQ-9). Logistic regression and stratified analysis of subgroups were used in this study.

RESULTS

Compared to those who consumed healthy and anti-inflammatory diets, the ORs for depression in groups consuming unhealthy and pro-inflammatory diets were 1.366 (95%CI:1.073,1.738) and 1.652 (95%CI:1.345,2.028), respectively. Sexual minorities have a higher risk of depression than heterosexuals. There is an interaction effect (P = 0.037) between HEI-2015 and sexual orientation on depression, while it was not found in DII. Subgroup analysis indicated that the interaction between sexual orientation and HEI-2015 persisted in males (P = 0.024), but not in females.

CONCLUSION

Both diet and sexual orientation had impacts on depression. There was an interaction between HEI-2015 and sexual orientation on depression, and this association was different by gender. Sexual minorities who are Gay/lesbian, Bisexual, and Something else are at higher risk for depression, and adopting healthy eating patterns and anti-inflammatory diets that are consistent with the recommendations of the USDA may appropriately reduce the risk of depression.

Sociodemographic and environmental characteristics associated with thoughts of death and suicidal ideation in community-dwelling residents of a rural town in Japan: analyses from a perspective of accompanying problems

OBJECTIVE

Suicide prevention has been focused on primary prevention as a group rather than individuals. However, we aimed to identify sociodemographic and environmental characteristics of individuals with suicidal thoughts among rural residents in Japan.

METHODS

In 2015, a cross-sectional home visit survey was conducted in a rural town in Akita Prefecture. A total of 1,844 residents aged ≥ 20 years (response rate, 65%) answered a self-administered questionnaire about suicidal thoughts in the past one month. Multivariate logistic regression analyses were used to investigate sociodemographic and environmental characteristics associated with suicidal thoughts in models with accompanying problems for human relations problems (HRP), health problems (HP), and financial problems (FP), or with no accompanying problems.

RESULTS

In total, 218 (men 9.4%, women 13.8%) had suicidal thoughts with accompanying problems for HRP (n = 104), HP (n = 112), and FP (n = 72). The risk characteristics were Kessler Psychological Distress Scale scores ≥ 9 in models with HRP, HP, and FP or with no accompanying problems; being a woman and current smoking with no accompanying problems; absence of a person for help in a model of FP; and absence of family member for help in a model of HRP or with no accompanying problems. The mitigating factor were being optimistic (a domain of resilience skills identified by factor analysis) in models of HRP, HP, and FP or with no accompanying problems; being aged 70-79 and being aged ≥ 80 in a model of HRP.

CONCLUSIONS

Suicidal thoughts among rural residents in Japan were associated with multifactorial sociodemographic and environmental characteristics.

Path of Physical Exercise's Impact on Deviant Behavior Among Chinese Adolescents

Purpose

Physical exercise is an important predictor of deviant behavior in adolescents; however, the paths and mechanisms underlying this relationship remain understudied.

Patients and Methods

This cross-sectional study used education tracking data of 8725 Chinese adolescents (4453 males, 4240 females, average age 14 ± 0.73) to construct a chain mediation model to explore whether sleep quality and mental health mediated the relationship between physical exercise and adolescent deviant behavior.

Results

The results show that physical exercise cannot directly predict adolescent deviant behavior; however, it can indirectly affect deviant behavior through the mediating effect of sleep quality and mental health as well as the chain mediating benefit of "sleep quality-mental health".

Conclusion

Sleep quality and mental health are important internal factors of physical exercise that inhibit deviant adolescent behavior. The lack of physical activity and poor sleep quality should be prioritized in interventions regarding deviant behavior among Chinese adolescents.

Adolescent smoking patterns: Associations with sociodemographic factors, cyberbullying, and psychiatric diagnoses in an outpatient clinical sample

There is a scarcity of research on smoking in adolescents within a clinical (outpatient) sample, and there is no existing knowledge on the relationship between cyberbullying and smoking in this population. The primary aim of this study is to determine the prevalence of smoking among adolescents in a clinical sample. Additionally, it aims to examine the potential associations between smoking status and factors such as socioeconomic characteristics, psychiatric diagnoses, and cyberbullying levels. A cross-sectional study was performed on 200 adolescents who visited a tertiary child and adolescent psychiatry outpatient clinic. Participants were assessed using the DSM-5 based psychiatric evaluation, the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version-DSM-5 Turkish Adaptation (K-SADS-PL-DSM-5-T), the Revised Cyber Bullying Inventory-II, and the Fagerström Test for Nicotine Dependence. The study found that 21% of the sample consisted of regular smokers, with a higher prevalence observed among older adolescents. The prevalence of depression and disruptive behavior disorders was significantly greater in the smoking group compared to other groups (p:0.043, p < 0.001, respectively). There was a significant difference in the scores for the cyberbullying bully subdimension among smokers (p = 0.013). The results of the multinomial logistic regression analysis indicated significant associations between smoking and age, maternal smoking status, friends smoking status, and a diagnosis of disruptive behavior disorder (p < 0.05 for all variables). This study reveals a significant prevalence of adolescent smoking in an outpatient clinic. These findings highlight the necessity of implementing focused smoking cessation interventions for this specific population.

E-cigarette use and other risk factors associated with tobacco smoking susceptibility among Australian adolescents

OBJECTIVE

To explore risk factors for smoking susceptibility among Australian adolescents to inform prevention policies and programs.

METHODS

Cross-sectional survey of students aged 12-17 years who reported having never smoked (n=4,171). Bivariate associations between smoking susceptibility and a range of factors previously linked to youth smoking and smoking susceptibility were initially examined, with significant factors (p<0.05) included in a final multivariable logistic regression model.

RESULTS

Eleven percent of adolescents who had never smoked were susceptible to smoking. Smoking susceptibility was independently associated with ever use of e-cigarettes (adjusted odds ratio [AOR]=3.26, 95% confidence interval [CI]: 1.83-5.81), perceiving those who smoke to be more popular (AOR=2.87, 95% CI: 1.62-5.10), having a close friend/s who smokes (AOR=2.66, 95% CI: 1.61-4.40), not perceiving smoking one or two cigarettes occasionally as personally dangerous (AOR=2.56, 95% CI: 1.61-4.09), and having symptoms of depression (AOR=1.59, 95% CI: 1.06-2.38).

CONCLUSIONS

The strongest smoking-initiation risk factor identified was ever use of e-cigarettes, with social norms, harm misperceptions around low-rate tobacco use and mental health also linked to smoking susceptibility.

IMPLICATIONS FOR PUBLIC HEALTH

Stronger e-cigarette regulations that reduce promotion to and access by youth, as well as interventions addressing the other identified risk factors, may help prevent future smoking uptake among Australian adolescents.

Nicotine neurotoxicity exacerbation following engineered Ag and Cu (50-60 nm) nanoparticles intoxication. Neuroprotection with nanowired delivery of antioxidant compound H-290/51 together with serotonin 5-HT3 receptor antagonist ondansetron

Nicotine abuse is frequent worldwide leading to about 8 millions people die every year due to tobacco related diseases. Military personnel often use nicotine smoking that is about 12.8% higher than civilian populations. Nicotine smoking triggers oxidative stress and are linked to several neurodegenerative diseases such as Alzheimer's disease. Nicotine neurotoxicity induces significant depression and oxidative stress in the brain leading to neurovascular damages and brain pathology. Thus, details of nicotine neurotoxicity and factors influencing them require additional investigations. In this review, effects of engineered nanoparticles from metals Ag and Cu (50-60 nm) on nicotine neurotoxicity are discussed with regard to nicotine smoking. Military personnel often work in the environment where chances of nanoparticles exposure are quite common. In our earlier studies, we have shown that nanoparticles alone induces breakdown of the blood-brain barrier (BBB) and exacerbates brain pathology in animal models. In present investigation, nicotine exposure in with Ag or Cu nanoparticles intoxicated group exacerbated BBB breakdown, induce oxidative stress and aggravate brain pathology. Treatment with nanowired H-290/51 a potent chain-breaking antioxidant together with nanowired ondansetron, a potent 5-HT3 receptor antagonist significantly reduced oxidative stress, BBB breakdown and brain pathology in nicotine exposure associated with Ag or Cu nanoparticles intoxication. The functional significance of this findings and possible mechanisms of nicotine neurotoxicity are discussed based on current literature.

[Non-smoker protection and tobacco cessation]

Non-smoker protection and tobacco cessation Abstract. Objective: Whereas, on the one hand, employees in child and adolescent psychiatric institutions (CAP) have to enforce smoking bans among patients, on the other hand, they have a high likelihood of being smokers themselves. Little data are available on the enforcement of smoking regulations and what cessation support is offered by CAP institutions. Method: In an online survey, n = 78 senior staff members or directors of German CAP institutions (41.9 % of all addressed CAP institutions) responded to questions on smoking regulations, exceptions, and cessation support for employees. Results: The enforcement of comprehensive smoking bans is rarely reported (<20 % of CAP institutions). Employees are exempted or allowed to smoke mostly outside of the building (e. g., in designated smoking areas: 69-78 % depending on ward type). Cessation support was offered by less than half of the CAP institutions (47%). Conclusions: The data presented point toward future areas for tobacco control in CAP care, including transparent regulations, staff training, and dissemination of support for occupational smoking cessation.

Menthol Flavor in E-Cigarette Vapor Modulates Social Behavior Correlated With Central and Peripheral Changes of Immunometabolic Signalings

The use of electronic cigarette (e-cigarette) has been increasing dramatically worldwide. More than 8,000 flavors of e-cigarettes are currently marketed and menthol is one of the most popular flavor additives in the electronic nicotine delivery systems (ENDS). There is a controversy over the roles of e-cigarettes in social behavior, and little is known about the potential impacts of flavorings in the ENDS. In our study, we aimed to investigate the effects of menthol flavor in ENDS on the social behavior of long-term vapor-exposed mice with a daily intake limit, and the underlying immunometabolic changes in the central and peripheral systems. We found that the addition of menthol flavor in nicotine vapor enhanced the social activity compared with the nicotine alone. The dramatically reduced activation of cellular energy measured by adenosine 5′ monophosphate-activated protein kinase (AMPK) signaling in the hippocampus were observed after the chronic exposure of menthol-flavored ENDS. Multiple sera cytokines including C5, TIMP-1, and CXCL13 were decreased accordingly as per their peripheral immunometabolic responses to menthol flavor in the nicotine vapor. The serum level of C5 was positively correlated with the alteration activity of the AMPK-ERK signaling in the hippocampus. Our current findings provide evidence for the enhancement of menthol flavor in ENDS on social functioning, which is correlated with the central and peripheral immunometabolic disruptions; this raises the vigilance of the cautious addition of various flavorings in e-cigarettes and the urgency of further investigations on the complex interplay and health effects of flavoring additives with nicotine in e-cigarettes.

Use of electronic vaping products and mental health among adolescent high school students in the United States: The moderating effect of sex

Although studies have investigated the association between conventional tobacco smoking and mental health outcomes among adolescents in the United States, few studies have examined the association between electronic vaping products (EVPs) and mental health among adolescents. This study aimed to investigate the cross-sectional association between EVPs use, symptoms of depression, and suicidal behaviors among adolescents. Data were pooled from the 2017 and 2019 Youth Risk Behavior Survey. An analytic sample of 14,285 adolescents (50.3% female) was analyzed using binary logistic regression. The outcome variables investigated were symptoms of depression, suicidal ideation, suicide plan, and suicide attempts, and the main explanatory variable was EVPs use. Of the 14,285 adolescents, 22.2%, 19.2%, and 58.8% were current, former and never users of EVPs, respectively. Controlling for other factors, current users of EVPs were significantly more likely to report having symptoms of depression (AOR = 1.82, 95% CI = 1.58-2.09), having suicidal ideation (AOR = 1.55, 95% CI = 1.30-1.86), making a suicide plan (AOR = 1.62, 95% CI = 1.34-1.97), or attempting suicide (AOR = 1.75, 95% CI = 1.41-2.18) when compared to never users of EVPs. Gender moderated the association between EVPs use, symptoms of depression, suicidal ideation, and suicide plan. Racial minority identity, sexual minority identity, sexual violence victimization, victim of school and cyberbullying, alcohol use, and cigarette smoking were all significantly associated with depression and suicidal behaviors. Study findings support the association between EVPs use and adolescent mental health. Future studies that employ longitudinal designs may offer more insight into the mechanisms underlying this association.
