Individual and Environmental Factors Associated with Tobacco Smoking, Alcohol Abuse and Illegal Drug Consumption in University Students: A Mediating Analysis

Addressing causal relationship between drinking behavior and metabolic syndrome: one-sample Mendelian randomization analysis

AIMS

Alcohol drinking is associated with central obesity, hypertension, and hyperlipidemia, which further causes metabolic syndrome (MetS). However, prior epidemiological studies on such associations lack experimental evidence for a causal relationship. This study aims to explore the causal relationship between drinking behavior and MetS in Taiwan population by using Mendelian randomization (MR) analysis.

METHODS

A cross-sectional study was conducted using the Taiwan Biobank database, which comprised 50 640 Han Chinese who were 30-70 years old without cancer from 2008 to 2020. In MR analysis, we constructed weighted and unweighted genetic risk scores by calculating SNP alleles significantly associated with alcohol drinking. We calculated odds ratios and 95% confidence interval (CI) by using a two-stage regression model.

RESULTS

A total of 50 640 participants were included with a mean age of 49.5 years (SD: 1.67 years), 36.6% were men. The adjusted odds ratio (aOR) of MetS per 5% increase in the likelihood of genetic predisposition to drink based on weighted genetic risk score with adjustment was 1.11 (95% CI: 1.10, 1.12, P < .001). Analysis was also conducted by grouping the likelihood of genetic predisposition to drink based on quartiles with multivariate adjustment. Using Q1 as the reference group, the aORs of MetS for Q2, Q3, and Q4 were 1.19 (1.12, 1.27, p < .001), 1.31 (1.23, 1.40, p < .001), and 1.87 (1.75, 2.00, p < .001), respectively, for the weighted genetic risk score.

CONCLUSIONS

This study shows a modest relationship between drinking behavior and MetS by using MR analysis.

Measuring the psychosocial impact of COVID-19 by means of the "international student well-being study questionnaire": Evidence on Italian university students

Background

The COVID-19 pandemic appeared as an unpredictable disruption of daily activities. This situation produced a unique mental health impact for the general population, youth, and vulnerable groups. A documented consequence has been alcohol abuse and impaired mental health. To our knowledge, no published study has yet evaluated the rates of depressive symptoms, academic frustration, and substance abuse in the Italian student population in the COVID era linking them to sociodemographic variables.

Aims

To investigate the incidence of depressive symptoms, academic frustration, and substance abuse students developed in one university in Northern Italy during the first COVID-19 outbreak, using a student wellbeing framework borrowed from Allardt's and Bronfenbrenner's theories.

Methods

Descriptive statistics, correlations, Wilcoxon test and factorial ANOVA were performed on data gathered through an online questionnaire sent to a convenience sample of university students. Data collection occurred between 18 May and June 21, 2020.

Results

According to the framework used, Being was the dimension of sociodemographic variables, Having was economic support and Loving was social support. Students experienced academic frustration and related depressive symptoms. Male gender seemed to be less affected by the depressive syndrome. With regard to economic support and related repercussions on depressive symptoms, students who reported that they could not obtain a loan showed significantly higher depressive symptoms. Students benefiting from greater financial support showed less academic frustration. Age appeared to be a predictor of academic frustration since young students proved to be the most frustrated. The examined students' population showed a significant decrease in alcohol and cigarettes consumption.

Conclusions

Having and Being dimensions influenced depression and academic frustration. Having and Loving dimensions were related with use of substances. The study findings support the implementation of interventions to help students, at a psychological, social, financial level aiming at fostering the quality of students' educational life.

Tobacco and alcohol co-use: Lifestyle and sociodemographic factors, and personality aspects as potential predictors in the "Seguimiento Universidad de Navarra" cohort

Tobacco and alcohol co-use are two major lifestyle modifiable risk factors. Understanding the determinants of both behaviors helps to develop interventions to prevent these exposures. However, previous studies have focused on predictors of individual tobacco or alcohol use. This study aims to explore the potential predictors of tobacco and alcohol co-use among Spanish university graduates from the "Seguimiento Universidad de Navarra" (SUN) cohort study. A total of 7175 participants who were co-users of tobacco and alcohol were selected for this cross-sectional analysis. Their mean age was 39.1 years (12.04 SD) and 57.3% were women. Univariate regression models were used to select the potential predictors of tobacco and alcohol co-use, and the areas under the ROC curves (AUC) were calculated. Multivariable logistic regression models were used to create a predictive model. Baseline potential predictors included sociodemographic factors, lifestyle habits, and perceived personality aspects. In the multivariable model, the main significant potential predictors of tobacco and alcohol co-use were driving under the influence of alcohol (odds ratio [OR] = 1.65 [1.43-1.90]), drinking 1-2 cups of coffee daily (OR = 1.50 [1.24-1.84]), drinking three or more cups of coffee daily (OR = 1.61 [1.35-1.91]), and doing more physical activity than recommended (OR = 1.18 [1.02-1.34]) when compared with the reference group. Conversely, those who were married (OR = 0.87 [0.75-0.99], ate at home 7 days a week (OR = 0.69 [0.60-0.80]), or had a high perceived level of competitiveness (OR = 0.83 [0.72-0.95]) had a lower risk of co-use (AUC 0.61 [confidence interval 95% 0.59-0.63]), compared to the reference group. These results could be used by healthcare professionals, especially nurses, to effectively assess patients at higher risk of tobacco and alcohol co-use.

Physical Activity Time, Alcohol Consumption, Mediterranean Diet, and Anxiety in Education Science Students

Student lifestyles change during university. This research aimed to classify university students according to their levels of physical activity, alcohol consumption, adherence to the Mediterranean diet, and anxiety and studied the relationships between the variables using a multigroup equation model according to gender. The sample was composed of 549 participants (M = 23.06; S.D. = 6.22), of whom 409 were women and 140 were men. Validated and adapted instruments such as the Beck Anxiety Inventory, the PREDIMED Questionnaire, and the Alcohol Use Disorder Identification Test were used. The data revealed four clusters through Ward's method and the k-means method. Regarding the exploratory model, differences were found in the effects of the variables according to sex. In conclusion, alcohol consumption was positively associated with the Mediterranean diet, and physical activity was negatively associated with the Mediterranean diet and anxiety.

Factors Associated with Self-Reported Changes in Alcohol Use among Young Adults during the COVID-19 Pandemic: A Comparative Analysis between Canada and France

While the COVID-19 pandemic impacted young adults' alcohol use patterns, little is known about how changes in alcohol use may differ across different settings. Our objective was to identify and compare factors associated with changes in alcohol use among young adults in Canada and France during the first year of the COVID-19 pandemic. We conducted an online cross-sectional survey in October-December 2020 with young adults aged 18-29 (n = 5185) in Canada and France. In each country, weighted multinomial logistic regressions were performed to identify factors associated with self-reported decrease and increase in alcohol use separately (reference: no change). Respectively, 33.4% and 21.4% reported an increase in alcohol use in Canada and France, while 22.9% and 33.5% reported a decrease. Being 25-29 was a predictor of decrease in Canada, while living away from family was associated with an increase in France. In both countries, participants were more likely to report an increase if they reported depressive symptoms, smoking tobacco, or cannabis use. Conversely, those who had been tested for COVID-19 and those who were highly compliant with COVID-19 preventive measures were more likely to report a decrease. Efforts are needed to develop alcohol use interventions for young adults, including in ways that prioritize those with mental health challenges.

Psychiatric symptoms, current use of tobacco, alcohol, illicit drug, and poly-substance among medical students in Eastern Turkey

The study aims to investigate the prevalence and patterns of substance use among medical students and to examine associated psychiatric symptoms. It has been observed that depression and psychoticism scores have a significant effect on smoking, and interpersonal sensitivity-hostility-paranoid ideation scores have a significant effect on drinking. It has been shown that interpersonal sensitivity and depression scores are more predictive of mono-and poly-substance use. Revealing the relationship between tobacco, alcohol, poly-substance use, and psychiatric symptoms in the medical school sample shows the importance of practices aimed at increasing students' awareness of their psychiatric symptoms and providing access to psychiatric services.

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 Impact of the Main Negative Socio-Economic Factors on Female Fertility

The negative relationship between fertility and income is well known to economists and demographers. Developed countries have experienced a remarkable decline in their fertility rate as they have become richer. Lifestyle choices can affect a woman’s ability to conceive. Tobacco use and heavy drinking is associated with an increased risk of ovulation disorders, and being overweight or significantly underweight can inhibit normal ovulation. Our research is focused on evaluating the main risk factors that influence female fertility. We assembled a country-specific dataset on birth rate and socio-economic factors for 171 countries, using data integrated from publicly available data sources. The regression model shows that the negative factor with the greatest impact on female fertility is represented by the level of income per capita. The negative effects of smoking, alcohol consumption, and body weight on female fertility are also demonstrated, but with a lower impact compared to the average income per capita.

Are There Neural Overlaps of Reactivity to Illegal Drugs, Tobacco, and Alcohol Cues? With Evidence From ALE and CMA

Abuses of most illegal drugs, including methamphetamine, marijuana, cocaine, heroin, and polydrug, are usually in conjunction with alcohol and tobacco. There are similarities and associations between the behavior, gene, and neurophysiology of such abusers, but the neural overlaps of their cue-reactivity and the correlation of neural overlap with drug craving still needs to be further explored. In this study, an Activation Likelihood Estimation (ALE) was performed on brain activation under legal (tobacco, alcohol) and illegal drug cues, for identifying the similarities in brain functions between different craving states. A Comprehensive meta-analysis (CMA) on the correlation coefficient between brain activation and craving scores in the selected literatures with subjective craving reports explained the degree of the craving via brain imaging results. In ALE, co-activation areas of the three cue-reactivity (posterior cingulate, caudate, and thalamus) suggest that the three cue-reactivity may all arouse drug-use identity which is a predictor of relapse and generation of conditioned reflexes under reward memory, thus leading to illegal drug relapses. In CMA, the brain activation was significantly correlated with subjective craving, with a correlation coefficient of 0.222. The neural overlap of tobacco, alcohol and most of the prevalent illegal drug cues not only further helps us understand the neural mechanism of substance co-abuse and relapse, but also provides implications to detoxification. Furthermore, the correlation between brain activation and craving is low, suggesting the accuracy of craving-based quantitative evaluation by neuroimaging remains unclear.

Addictive profiles of Lebanese university students in terms of smoking, alcohol, and illegal drug use

The Lebanese economic crisis, financial crisis, and USD shortage were conducive to an increased drug addiction especially for students who feel that their future in Lebanon is not safe, as well as the psychological fragility of the Lebanese people, and the more permissive sociocultural context. Our study aimed to assess the addiction levels and profiles of university students in Lebanon, and thus to evaluate the rapid rising in dependence regarding smoking, alcohol, and illegal drug use during this crisis. This cross-sectional study was carried out between February and September 2020. A total of 467 participants (315 females, 152 males; Mage = 23.48 ± 6.03) were recruited through convenience sampling through several universities in Lebanon's governorates. Participants received the online link to the survey. Students were divided into three clusters as follows: cluster 1, which corresponds to students with moderate addictions; cluster 2, which corresponds to students with high addictions; and cluster 3, which corresponds to students with low addictions. When comparing cluster 1 to cluster 3, the results of the multinomial regression showed that older age (aOR=1.08) and having a high monthly income compared to no income (aOR=2.78) were significantly associated with higher odds of being in cluster 1 compared to cluster 3. When comparing cluster 2 to cluster 3, the results of the multinomial regression showed that female gender (aOR=0.19) was significantly associated with lower odds of being in cluster 2 compared to cluster 3, whereas having a dead (aOR=16.38) or divorced parent (aOR=6.54) and having a low (aOR=3.93) or intermediate income compared to zero income (aOR=4.71) were significantly associated with higher odds of being in cluster 2 compared to cluster 3. The results of our study revealed a considerable prevalence of addiction to alcohol, illicit drugs, and specially to smoking, among Lebanese university students. These findings emphasize the need to implement firm policies and rules in an attempt to minimize the tendency of the young population to engage in such addictions.

[Post-operative prevalence of dysphagia in head-and-neck cancer patients in the acute care units]

OBJECTIVE

 Dysphagia constitutes a frequent post-operative functional impairment in head-and-neck cancer patients. This impairment can result in aspiration/penetration and limitations of oral intake. Therefore, often it requires a therapeutic intervention. In this study, prevalence of post-operative dysphagia and its associations with the tumour stage, localisation, patients' age, and biological sex were analysed for the inpatient treatment setting.

MATERIAL AND METHODS

 A total of 201 adult head-and-neck cancer patients (mean age 63 years) were analysed prospectively by FEES in two university hospitals in regard to their penetration/aspiration, limitations of oral intake, and need for therapeutic interventions directly after the operative tumour treatment. Additionally, the influence of the same patients' characteristics on these three parameters were analysed by means of univariate and multivariate statistical methods.

RESULTS

 Out of 201 patients, 66.7 % needed a therapeutic intervention because of their dysphagia, 57.2 % needed a nasogastral or PEG tube due to limitations of oral intake, 45.3 % had an aspiration. In the latter subgroup, 38.5 % had a silent aspiration. Higher tumour stage, patients' higher age and male sex were shown to be significant influence factors for dysphagia, tumour localisation showed only a marginally significant result.

CONCLUSIONS

 The study demonstrated a clinical importance and relevance of the consequent and systematic treatment of post-operative dysphagia in head-and-neck cancer patients in the acute care units as a constituent of a modern oncological therapy.

Medication overuse and drug addiction: a narrative review from addiction perspective

Chronic headache is particularly prevalent in migraineurs and it can progress to a condition known as medication overuse headache (MOH). MOH is a secondary headache caused by overuse of analgesics or other medications such as triptans to abort acute migraine attacks. The worsening of headache symptoms associated with medication overuse (MO) generally ameliorates following interruption of regular medication use, although the primary headache symptoms remain unaffected. MO patients may also develop certain behaviors such as ritualized drug administration, psychological drug attachment, and withdrawal symptoms that have been suggested to correlate with drug addiction. Although several reviews have been performed on this topic, to the authors best knowledge none of them have examined this topic from the addiction point of view. Therefore, we aimed to identify features in MO and drug addiction that may correlate. We initiate the review by introducing the classes of analgesics and medications that can cause MOH and those with high risk to produce MO. We further compare differences between sensitization resulting from MO and from drug addiction, the neuronal pathways that may be involved, and the genetic susceptibility that may overlap between the two conditions. Finally, ICHD recommendations to treat MOH will be provided herein.

Prevalence of Substance Use in University Students, Ethiopia

BACKGROUND

Although substance use is a known public health problem and a pressing issue in Ethiopia, its real extent and magnitude are not yet properly explored. The current study aimed to determine the extent and predictors of substance use among regular undergraduate students in the Institute of Technology, Addis Ababa University.

METHODS

An institution-based cross-sectional study was carried among 794 undergraduate regular students at the Institute of Technology, Addis Ababa University, using a self-administered structured questionnaire filled by study participants. Data entry, cleaning, and coding were performed by EPI-INFO version 3.5.1. Statistical Package for Social Sciences; AOR: Adjusted odds ratio (SPSS) SPSS version 21 software was used to analyze data by performing descriptive statistics, bivariate, and multivariate analysis.

RESULTS

73.7% of the study participants used substances at least once. The lifetime use of each substance includes alcohol (68.2%), khat (53.6%), cigarettes (46.1%), and illicit drugs (23.3%). Loss of family (AOR [95%CI], 34.50 [7.569, 157.263]), pocket money between 500 and 999 Ethiopian birr (AOR [95%CI], 9.978 [1.240, 80.280]), and above 1000 Ethiopian birr (AOR [95%CI], 10.831 [1.333, 87.971]) were identified predictors for khat use. The odds of lifetime alcohol use was higher among students coming from a divorced family (AOR [95%CI], 9.346 [3.162, 27.625]), lost one (AOR [95%CI], 37.406 [11.375, 123.008]), or both of their parents (AOR [95%CI], 18.750 [5.798, 60.633]). Students of urban origin (AOR [95%CI], 3.214 [1.950, 5.296]), and students with anxiety symptoms (AOR [95%CI], 2.655 [1.981, 3.557]) have a higher odds of lifetime cigarette smoking. The lifetime exposure to illicit drugs is higher among students in age groups between 20 and 24 years (AOR [95%CI], 5.963 [1.361, 26.135]), students coming from substance user family (AOR [95%CI], 2.172 [1.161, 4.063]), and students of urban origin (AOR [95%CI], 2.661 [1.202, 5.889]).

CONCLUSION

A higher prevalence of substance use requiring administrative and educational interventions was observed. Awareness creation interventions on the potential impacts of substance abuse should be performed.

The Effect of Peer Education on Decision-Making, Smoking-Promoting Factors, Self-Efficacy, Addiction, and Behavior Change in the Process of Quitting Smoking of Young People

Purpose

The study aims to examine the effect of peer education on the decision to quit smoking, factors that encourage smoking, self-efficacy, addiction, and behavior change in students who apply to the Youth Friendly Center to quit smoking.

Participants and Methods

This research is a Randomized Controlled Trials study. The experimental group consisted of students who were enrolled in the peer education course (n=759). The control group has consisted of students (n=1095) who did not enroll in this course.

Results

Participants in the experimental group to quit smoking, more than the control group (p>0,01). The addiction level of the participants in the experimental group, less than the participants in the control group (p>0,01). According to the scores of the participants in the control group of the participants in the experimental group, the factors that trigger smoking, and the benefit sub-dimension scores in the Decision Balance Scale were low. Loss sub-dimension scores, which show the losses from the harms of smoking, increased significantly in the Self-Efficacy Scale, Behavior Change Process Scale, and Decision Balance Scale (p>0,01).

Conclusion

Peer educators trained by the researcher and her team in the Youth Friendly Center Smoking Quit Program have an important effect in supporting/improving the cognitive and behavioral change processes of university students in smoking quit compared to those who do not receive an education. 94% success of the smoking quit program; Students’ voluntary application to receive professional support, students’ voluntary attendance of the treatment program for 6 months, strong communication and feedback, effective and functional professional counseling, and social support depend on strengthening the program with peer education. Especially with peer education, the development of leadership and role model characteristics made the smoking quit program preferred by students.

Sex- and age-dependent differences in nicotine susceptibility evoked by developmental exposure to tobacco smoke and/or ethanol in mice

Either tobacco smoking or alcohol consumption during pregnancy sex-selectively increases susceptibility to drugs of abuse later in life. Considering that pregnant smoking women are frequently intermittent consumers of alcoholic beverages, here, we investigated whether a short-term ethanol exposure restricted to the brain growth spurt period when combined with chronic developmental exposure to tobacco smoke aggravates susceptibility to nicotine in adolescent and adult mice. Swiss male and female mice were exposed to tobacco smoke (SMK; research cigarettes 3R4F, whole-body exposure, 8 h/daily) or ambient air during the gestational period and until the tenth postnatal day (PN). Ethanol (ETOH, 2 g/Kg, 25%, i.p.) or saline was injected in the pups every other day from PN2 to PN10. There were no significant differences in cotinine (nicotine metabolite) and ethanol serum levels among SMK, ETOH and SMK + ETOH groups. During adolescence (PN30) and adulthood (PN90), nicotine (NIC, 0.5 mg/Kg) susceptibility was evaluated in the conditioned place preference and open field tests. NIC impact was more evident in females: SMK, ETOH and SMK + ETOH adolescent females were equally more susceptible to nicotine-induced place preference than control animals. At adulthood, SMK and SMK + ETOH adult females exhibited a nicotine-evoked hyperlocomotor profile in the open field, with a stronger effect in the SMK + ETOH group. Our results indicate that ethanol exposure during the brain growth spurt, when combined to developmental exposure to tobacco smoke, increases nicotine susceptibility with stronger effects in adult females. This result represents a worsened outcome from the early developmental dual exposure and may predispose nicotine use/abuse later in life.

A Social Ecological Approach to Hazardous Alcohol Use among Flemish Higher Education Students

Hazardous use of alcohol is a global public health concern. Statistics suggest that this is particularly common in Europe, and among higher education students. Although it has been established that various factors—ranging from the individual to the overarching societal level—are associated with misuse of alcohol, few studies take multiple levels of influence into account simultaneously. The current study, therefore, used a social ecological framework to explore associations between variables from multiple levels of influence and the hazardous use of alcohol. Data were obtained from a representative sample of higher education students from Flanders, Belgium (n = 21,854), and explored using hierarchical multiple regression analyses. The results demonstrated that the individual, interpersonal, organizational, community, and policy levels, were all associated with risky alcohol consumption. When devising interventions, policymakers should, therefore, take into consideration that variables from multiple levels of influence are at play. Students’ capacities to change or maintain their alcohol consumption behaviors may be undermined if social settings, overarching environments, social norms, and policies are not conducive to their motivations and social expectations.

Cigarette, E-Cigarette and Waterpipe Use among Young Adults: Differential Cognitions about These Three Forms of Smoking

Background: Polytobacco use is common among young adults. The purpose of the present study was to investigate a number of cognitions related to the use of three tobacco products (cigarettes, e-cigarettes and waterpipes) among young adults. Methods: Participants (n = 799, 59.4% women) aged 18–25 years old (M = 21.8, SD = 1.7) completed an online tobacco cognitions questionnaire. Results: For all three tobacco products, there was significantly more agreement with the cognition “I would smoke if my best friend offered” among tobacco users (used one or more tobacco products) than among non-users. For e-cigarettes and waterpipes, there was significantly more agreement with the cognition “It would be easy to quit these products” than was reported by non-users. Polytobacco users (three tobacco products) endorsed the cognitions scale (the six cognition items were combined to form a single cognitions scale for each tobacco product) significantly more than non-users for cigarettes and e-cigarettes. Furthermore, waterpipe users, polytobacco users, dual users and single users all endorsed the combined cognitions scales more strongly than non-users. Conclusions: Efforts to prevent polytobacco use should ensure that young adults have the necessary self-efficacy to resist peer pressure and provide them with clear information about the health risks associated with using alternative tobacco products.
