Work-related stress factors associated with problem drinking: A study of the Spanish working population

Escape or activate? Pathways of work stress on substance use

BACKGROUND

Research on the spillover effects of work stress on substance use have mainly focused on the concept of escapist substance.

OBJECTIVE

Building on the concept of self-endangering work behavior, we expand this stress-theoretic view with a presenteeism path of work-induced substance use. Contrary to emotion-based disengaging coping strategies associated with escapist use, we argue that high job demands may also promote problem-focused engagement coping, where substances are used for activation.

METHODS

A structural equation model was used to analyze both assumed pathways of stress-induced substance use with survey data from a random sample of n = 411 employees.

RESULTS

We confirmed that high job demands are directly related to escapist substance use, but indirectly related to activating substance use, mediated by presenteeism behavior. Both types of substance use are reduced in organizations with high psychosocial safety climate, but increase with higher competitive climate. Social support is related to reduced activating substance use. Males show a stronger tendency for the escapist path, whereas the presenteeism path is more prevalent in women.

CONCLUSION

Work stress may not only induce substance use as a disengaging emotional coping strategy, but also as an active problem-focused coping strategy, where employees engage in substance use to continue their efforts necessary for work-related goal attainment. A psychosocial safety climate may provide opportunities for intervening on the "cause of causes" of substance use. Moreover, due to the higher prevalence for activating substance use in female workers, previous research may have underestimated women's risks for work-induced substance use.

Patterns of polysubstance use among adults in Malaysia-A latent class analysis

INTRODUCTION

Polysubstance use is the use of more than one non-prescribed licit or illicit substance at one time. This is a common phenomenon, but little is known about the severity and the various substances used by adults in Malaysia.

OBJECTIVE

To determine the pattern of polysubstance use and its associated factors among general adults in Malaysia.

METHODOLOGY

This was a secondary data analysis from the National Health and Morbidity Survey (NHMS) 2019), a cross-sectional population survey with a two-stage stratified random sampling design. A total of 10,472 Malaysians aged 18 years and above participated in this survey. Polysubstance use was defined as concurrent use of more than one substance, either alcohol, tobacco, or drugs (opioids, marijuana, amphetamine/ methamphetamine or kratom). A latent class analysis (LCA) was used to identify the membership of polysubstance groups. The association of class membership with demographic profiles was examined using Multinomial Logistic Regression analysis.

RESULTS

Fit indices (AIC = 16458.9, BIC = 16443.6) from LCA supported 3 classes solution: Class 1; "moderate-drug" group primarily combination used of tobacco and alcohol (2.4%), Class 2; "high-drug" group using multiple substance including kratom (0.3%) and Class 3; "low-drug" group reporting minimal alcohol and tobacco use or non-user (97.3%). The multinomial model showed young adults (18-40 years) had a higher likelihood of being polysubstance users both for moderate-drug class (OR = 4.1) and high-drug class (OR = 3.9) compared to older age (≥60 years). Chinese (OR = 18.9), Indian (OR = 23.3), Indigenous Sabah & Sarawak (OR = 34.6) and others ethnicity (OR = 8.9) showed higher odds of being moderate-drug users than Malays. The greater odds of moderate-drug use for males (OR = 35.5), working groups (OR = 1.5) and low education level group (OR = 3.2).

CONCLUSION

Our study highlights patterns and demographics related to the use of polysubstances among adults in Malaysia. These results would help formulate specific prevention programmes for these high-risk groups.

Association between work stress and health behaviours in Korean and Japanese ageing studies: a cross-sectional study

OBJECTIVES

Limited research has focused on the association between work stress and health behaviours in Asian countries. We aimed to explore the effect of work stress on two health behaviours among employees aged 45 years or above in two countries with ageing populations, Korea and Japan.

DESIGN

A cross-sectional study.

SETTING

This secondary data analysis was conducted on baseline data from the Korean Longitudinal Study of Aging (KLoSA, 2006) and the Japanese Study of Aging and Retirement (JSTAR, 2007 and 2009).

PARTICIPANTS

Included in the analytical sample were 4982 responders without missing data aged 45 years or older who reported work positions and hours (KLoSA n=3478, JSTAR n=1504).

MAIN OUTCOME MEASURES

Work stress was represented by the short version of the effort-reward imbalance (ERI) model. We used logistic regression and multinomial logistic regression to investigate the association between work stress and smoking (binary current smoking) and between work stress and drinking (categorical volume of alcohol). Socioeconomic and work-related characteristics were taken into consideration, and we examined the potential interaction between ERI and gender.

RESULTS

Work stress as measured by ERI ratio was significantly associated with both smoking and drinking in the KLoSA analysis; after the model was fully adjusted, ORs were 1.45 (95% CI 1.17 to 1.80) and 1.44 (95% CI 1.09 to 1.90), respectively. In analysis of the data from JSTAR, the ERI ratio was associated with smoking (OR 1.37, 95% CI 1.01 to 1.89) but not with drinking. No statistically significant interaction was found between ERI and gender in any model (p=0.82 in KLoSA data and p=0.19 in JSTAR data).

CONCLUSIONS

Statistically significant associations were found between work stress and both smoking and drinking behaviours in Korea and between work stress and smoking in Japan. Government integration of effort-reward balance programmes and health promotion programmes could effectively promote population health in these two Asian countries.

Characteristics of Workplace Psychosocial Resources and Risk of Diabetes: A Prospective Cohort Study

OBJECTIVE

To examine whether characteristics of workplace psychosocial resources are associated with the risk of type 2 diabetes among employees.

RESEARCH DESIGN AND METHODS

Participants were 49,835 employees (77% women, aged 40-65 years, and diabetes free at baseline) from the Finnish Public Sector cohort study. Characteristics of horizontal (culture of collaboration and support from colleagues) and vertical (leadership quality and organizational procedural justice) psychosocial resources were self-reported. Incident type 2 diabetes (n = 2,148) was ascertained through linkage to electronic health records from national registers. We used latent class modeling to assess the clustering of resource characteristics. Cox proportional hazards models were used to examine the relationship between the identified clusters and risk of type 2 diabetes during 10.9 years of follow-up, adjusting for age, sex, marital status, educational level, type of employment contract, comorbidity, and diagnosed mental disorders.

RESULTS

We identified four patterns of workplace psychosocial resources: unfavorable, favorable vertical, favorable horizontal, and favorable vertical and horizontal. Compared with unfavorable, favorable vertical (hazard ratio 0.87 [95% CI 0.78; 0.97]), favorable horizontal (0.77 [0.67; 0.88]), and favorable vertical and horizontal (0.77 [0.68; 0.86]) resources were associated with a lower risk of type 2 diabetes, with the strongest associations seen in employees at age ≥55 years (Pinteraction = 0.03). These associations were robust to multivariable adjustments and were not explained by reverse causation.

CONCLUSIONS

A favorable culture of collaboration, support from colleagues, leadership quality, and organizational procedural justice are associated with a lower risk of employees developing type 2 diabetes than in those without such favorable workplace psychosocial resources.

Stress and psychoactive substance use among university professors

INTRODUCTION:

University professors are highly susceptible to work-related stress, and psychoactive substance use is often used as a stress alleviation strategy. This issue has attracted the attention of organizations that represent these workers given its potential repercussions on work and personal life.

OBJECTIVES:

This study aimed to evaluate the association between work-related stress and psychoactive substance use in university professors.

METHODS:

A descriptive and analytical-qualitative study was conducted in a public university in the countryside of the state of Rio Grande do Norte, Brazil. Data were collected from 67 professors using Google Forms and the following instruments: sociodemographic characteristics and occupational activity questionnaire; Alcohol, Smoking and Substance Involvement Screening; and Stress Symptom Inventory. Descriptive methods were used to calculate means and standard deviations. The association between occupational stress, substance use, and the variables studied was investigated using chi-square or Fisher’s exact tests.

RESULTS:

Most participants were men, married, with children, and a master’s-level education. The mean age of the sample was 42 years. Differences were observed between the prevalence of legal and illegal substance use. Many participants were in the alert, resistance, or exhaustion stages of stress, with the resistance stage being the most frequent. Alcohol was the substance most commonly associated with work-related stress.

CONCLUSIONS:

Psychoactive substance use is associated with work-related stress among university professors.

Depression as a Mediator in the Association of Work-Family Conflict With Problem Drinking Among Young and Middle-Aged Korean Married Workers

OBJECTIVE

This study examined the associations of work-family conflicts (WFC) with problem drinking and the mediating effect of depression among Korean married workers.

METHODS

The data of 2386 married workers were used from the 2017 Korean Welfare Panel Study. The data classified into two groups, young adults and middle-aged based on age 45. The association of WFC with problem drinking and the mediating effect of depression was assessed by combining logistic and linear regression.

RESULTS

WFC was associated with problem drinking, and the mediating effect of depression was significant in the middle-aged group. Meanwhile, depression only has a direct effect on problem drinking in the young adult group.

CONCLUSION

A strategy for treating depression may be important for countering problem drinking. However, an age-tailored intervention should be considered WFC supporting middle-aged workers.

Intraindividual association between shift work and risk of drinking problems: data from the Finnish Public Sector Cohort

OBJECTIVES

Studies concerning the association between shift work and drinking problems showed inconsistent results. We used data from a large occupational cohort to examine the association between shift work and different types of drinking behaviour.

METHODS

A total of 93 121 non-abstinent workers from the Finnish Public Sector Study were enrolled in the study. Six waves of survey data were collected between 2000 and 2017. Work schedules were categorised as regular day, non-night shift and night shift work, and shift intensities were calculated from registered working hour data. Two indicators of adverse drinking behaviour were measured: at-risk drinking (>7 and >14 drinks per week in women and men, respectively) and high-intensity drinking (measured as pass-out experience). Intraindividual analysis was conducted using fixed-effects regression to examine the association between shift work and drinking behaviours.

RESULTS

Compared with regular day work, night shift work was associated with an increased risk of high-intensity drinking (OR 1.28, 95% CI 1.07 to 1.52) but a lower risk of at-risk drinking (OR 0.85, 95% CI 0.74 to 0.99). Shift workers who worked long shifts had a lower risk of at-risk drinking compared with those who rarely worked long shifts (OR 0.58, 95% CI 0.37 to 0.93).

CONCLUSIONS

Associations between shift work and alcohol use vary according to drinking patterns. Workers engaged in high-intensity drinking more often during night shift schedules compared with day work, but did not drink averagely higher volume.

A Context-Specific Instrument to Record Drinking Behaviour: A Pilot Study on Implications of Identifying the Context of Risky Drinking

A context-specific quantity-frequency (CSQF) questionnaire has been developed to accurately measure alcohol consumption using probing questions on drinking context. The study aimed to describe the drinking context associated with different drinking intensities in a community of southern Thailand using the CSQF. A cross-sectional survey was conducted among adults aged > 15 years in Songkhla Province, Thailand. Among 804 participants, there were 183 current drinkers with 412 drinking events (215 low-, 79 medium-, and 118 high-intensity). More than half of these events occurred in special situations (i.e., holiday, party, and cultural drinking). About half of the drinking events occurred outside the drinker's house and most drinking events occurred among friends. Higher drinking intensity was associated with higher level of education [adjusted odds ratio (aOR) 4.74 for medium- and aOR 5.23 for high-intensity] and with a special drinking situation (aOR 2.46 for medium- and aOR 2.78 for high-intensity).

Inequalities and the Impact of Job Insecurity on Health Indicators in the Spanish Workforce

In a context of high job insecurity resulting from social deregulation policies, this research aims to study health and substance abuse inequalities in the workplace from a gender perspective. To this end, a transversal study was carried out based on microdata from the National Health Survey in Spain—2017, selecting the active population and calculating the prevalence of the state of health and consumption, according to socio-occupational factors (work relationship, social occupational class, time and type of working day). Odds ratios adjusted by socio-demographic variables and their 90% confidence intervals were estimated by means of binary logistic regressions stratified by sex. The results obtained showed two differentiated patterns of health and consumption. On the one hand, unemployed people and those from more vulnerable social classes showed a higher prevalence of both chronic depression and anxiety and of hypnosedative and tobacco use. On the other hand, the better positioned social classes reported greater work stress and alcohol consumption. In addition, while unemployment affected men’s health more intensely, women were more affected by the type of working day. The study can be used to design sustainable preventive occupational health policies, which should at least aim at improving the quantity and quality of employment.

[Factors involved in job insecurity and their relationship with the health of salaried workers and contract workers in BoliviaRelação entre condições precárias de trabalho e a saúde dos trabalhadores assalariados e contratados na Bolívia]

OBJECTIVE

To examine the association between factors involved in job insecurity and: health service use, tobacco use, and alcohol use among salaried workers and contract workers in Bolivia.

METHODS

A cross-sectional study was performed with a sample of workers composed of 1203 women and 1780 men between the ages of 14 and 65 years using data from Bolivia's 2015 Household Survey. The dependent variables were health service use, tobacco use, and alcohol use; the independent variables were wages, type of contract, work hours, and exercise of workers' rights. Prevalence rates were calculated and the association between factors involved in job insecurity and the dependent variables was assessed using multivariate binomial regression models with adjustment for sociodemographic variables. The analyses were stratified by sex.

RESULTS

The adjusted models showed a significant association between working under a temporary contract and lower use of health services among men (odds ratio [OR]: 0.70; 95% confidence interval [95% CI]: 0.56-0.87) and women (OR: 0.62; 95% CI: 0.46-0.82). Poor exercise of workers' rights was also associated with lower use of health services (OR: 0.61; IC 95%: 0.45-0.83) among men. Long work hours showed an association with greater use of alcohol among women (OR: 1.75; 95% CI: 1.34-2.29). Low wages were associated with lower tobacco use among men (OR: 0.75; 95% CI: 0.57-0.99) and women (OR; 0.57; 95% CI: 0.33-0.99). However, being a manual worker was associated with tobacco use (OR: 1.36; 95% CI: 1.09-1.70) among men.

CONCLUSIONS

Having a temporary contract and belonging to income quintile I (the poorest) are both associated with lower use of health services and lower probability of smoking in individuals of either sex. Long work hours are associated with greater alcohol use among women. Poor exercise of workers' rights is associated with lower use of health services among men.

Job exposure to the public in relation with alcohol, tobacco and cannabis use: Findings from the CONSTANCES cohort study

Objectives

To examine the associations between job exposure to the public (e.g., customers, guests, users of a public service, patients) and alcohol, tobacco and cannabis use.

Methods

From the French population-based CONSTANCES cohort, 16,566 men and 17,426 women currently working were included between 2012 and 2016. They reported their exposure to the public (daily versus no daily), and among the daily exposed participants (10,323 men and 13,318 women), the frequency of stressful exposure (often versus rarely). Dependent variables were: chronic alcohol consumption (<1(1), 1-27(1–13), 28-42(14–28), >42(28) drinks per week in men(women)), heavy episodic drinking (never, at most once a month, more than once a month), alcohol use risk with Alcohol Use Disorders Identification Test (mild, dangerous, problematic or dependence), tobacco use (non-smoker, former smoker, 1–9, 10–19, >19 cigarettes per day) and cannabis use (never, not in past year, less than once a month, once a month or more). Logistic regressions provided odds ratios of substance use, stratifying for gender and adjusting for sociodemographic confounders, depression, effort-reward imbalance and perceived health status.

Results

Exposed men had higher risks of alcohol (chronic alcohol consumption, heavy episodic drinking and alcohol use risk), tobacco and cannabis use. Exposed women had higher risks of tobacco and cannabis use. In men, stressful exposure was associated with increased risks of heavy episodic drinking, tobacco and cannabis use. In women, stressful exposure was associated with increased risks of chronic alcohol consumption, alcohol use risk, tobacco and cannabis use. All these findings remained significant in multivariable analyses, taking into account sociodemographic variables, depressive symptoms, perceived health status and effort-reward imbalance.

Conclusions

Interventions to reduce emotional job demand should systematically integrate assessment and prevention measures of addictive behaviors. Vulnerable workers may be offered more specific interventions to reduce the impact of exposure to the public on their substance use.

Association between psychosocial work conditions and latent alcohol consumption trajectories among men and women over a 16-year period in a national Canadian sample

BACKGROUND

It is unclear how psychosocial working conditions influence future alcohol consumption. Using group-based trajectory modelling, this study aimed to determine: the number of latent alcohol consumption trajectories over 16 years in a representative sample of the Canadian workforce; the association between psychosocial working conditions and longitudinal alcohol consumption; and if the association between psychosocial work factors and longitudinal alcohol consumption differed among men and women.

METHODS

We included 5458 employed adults from the longitudinal Canadian National Population Health Survey. Average daily alcohol consumption was measured every 2 years from 1994 to 2010. Psychosocial work factors were measured in 1994 using the Job Content Questionnaire. Group-based trajectory modelling was used to derive the appropriate number of alcohol behaviour trajectories. The association between psychosocial work factors and alcohol trajectory membership was estimated using multinomial logistic regression. Models were stratified by sex to determine if these associations differed among men and women.

RESULTS

Three alcohol consumption trajectories were present: non-drinkers, light drinkers (0.5-1 drinks/day) and moderate drinkers (2-3 drinks/day). Higher workplace physical exertion and lower social support levels were associated with membership in the moderate drinking trajectory. Among men, lower psychological demands and higher physical exertion levels were associated with membership in the moderate drinking trajectory. Among women, lower levels of physical exertion were associated with membership in the light drinking trajectory, and higher psychological demand levels were associated with membership in the moderate drinking trajectory.

CONCLUSIONS

Our study suggests that workplace physical exertion and psychological demands may be associated with different alcohol consumption trajectories among men and women.

Work-related stress, associated comorbidities and stress causes in French community pharmacies: a nationwide cross-sectional study

Background

Like other health professionals, community pharmacists are exposed to stress factors (being efficient, avoiding mistakes and bearing emotional load), but they are also under the pressure of entrepreneurial responsibilities. The main objective was to assess the level of work-related stress in French community pharmacies. The other objectives of the study were to assess the associated comorbidities and causes of work-related stress.

Methods

This observational cross-sectional study was sent to all French community pharmacies by email. The survey was anonymous and designed to collect the following items: socio-demographic factors, professional status, characteristics of community pharmacy, work-related stress (visual analogic scale—VAS), fatigue (VAS), sleep disturbances (questions), anxiety and depression symptoms (hospital anxiety and depression scale), medical consultation for work-related stress, medication use for work related stress, psychoactive drug-use and causes of work-related stress. Participants were included in the survey if they were pharmacists (owner or assistant) or pharmacy technicians working in a community pharmacy at the time of the survey. Exclusion criteria were defined as follows: pharmacy students or other professionals involved in a community pharmacy (e.g. dietician, beautician) and lack of professional status information. There was no age limitation.

Results

After three months of data collection, 1,339 participants answered the survey and 1,272 participants were included in conformity with the inclusion and exclusion criteria, and to avoid missing data on the primary endpoint. Work-related stress was detected in 32.8% (417/1,272) of individuals (scores ≥70/100). Men were significantly more affected than women and there was no difference between professional statuses and no relation with the age of the participants. Work-related stress was significantly associated with anxiety, depression, fatigue, sleep disturbances, medical consultations, medication use, alcohol consumption above the WHO recommendations for men and psychoactive drug use. Three causes of stress were clearly identified and related to stress levels, workload, working atmosphere and deterioration of work quality. However, causes of work-related stress were significantly different among professionals, for example: entrepreneurial burden for pharmacists-in-charge and workload for employees (assistant pharmacists and pharmacy technicians).

Discussion

Work-related stress has a very strong impact in French community pharmacies. This stress was associated with several comorbidities and induces health resource consumption. Several causes of work-related stress have been identified such as workload, working atmosphere and deterioration of work quality; however, these causes could be detected and managed to improve stress levels. We recommend developing individual and organizational stress management in French community pharmacies.

Do causes of stress differ in their association with problem drinking by sex in Korean adolescents?

BACKGROUND

Previous studies have focused mainly on whether stress causes present drinking or excessive drinking. However, few studies have been conducted on the relationship between stress and problem drinking in adolescents. The objective of this study was to examine the stress level and the cause of stress related to problem drinking behavior according to sex among Korean youth.

METHOD

Data for this study were pooled from cross-sectional data collected annually from 2007 through 2012 from the Korea Youth Risk Behavior Web-based Survey. A representative sample of 442,113 students from 800 randomly selected middle and high schools in Korea were included. Multiple logistic regression models were used in the analysis.

RESULTS

Both male and female students with extremely high stress were more likely to engage in problem drinking than were students with no stress (odds ratios [OR], 1.73 in males and 1.41 in females). The major causes of stress in male students that were associated with problem drinking were conflict with a teacher, trouble with parents, and peer relationships (ORs, 2.47, 1.72, and 1.71, respectively), whereas there are no statistically significant association between causes of stress and problem drinking among female students. Considering stress level, Male students with extremely high stress level were associated with problem drinking regardless of causes of stress, while Female students who felt extremely high levels of stress were more likely to engage in problem drinking due to stress from a conflict with parents, peer relationships, appearance, and financial difficulty (ORs, 1.53, 1.53, 1.46, and 1.47, respectively).

CONCLUSION

Adolescents who engage in problem drinking may be affected by different causes of stress according to sex. Thus, appropriate approaches that reflect sex differences will be helpful to alleviate problem drinking in adolescents and educational authorities need to arrange more effective education program for drinking given positive associations between drinking education and problem drinking.

Gender differences in the use of alcohol and prescription drugs in relation to job insecurity. Testing a model of mediating factors

BACKGROUND

The results of several studies suggest that economy-related stressors are less distressing for women compared with men. This study proposed to examine the relationship of perceived job insecurity with the use of licit drugs using a theoretical model that considered antecedents and mediators of this association, in order to identify differences between working men and women.

METHODS

Using information from the Catalan Health Survey (2010-2014), we selected working individuals aged 16-64 who were primary providers of household income (N=5315). The outcomes were two measures of alcohol consumption (heavy drinking and binge drinking) and the use of hypnotics/sedatives. As antecedents of the exposure to job insecurity we considered the type of contractual relationship and occupational class. The mediating factors were poor mental health, household structure and the hours of housework per week. The theoretical model was assessed using path analysis where the moderating effect of gender was considered in all the associations.

RESULTS

No differences in the prevalence of job insecurity were found between men and women (17%). Job insecurity (Odds ratio [OR]=1.35, 95% confidence interval [CI]=1.23-1.48) and house workload (OR=1.01, 95% CI=1.00-1.02) were positively associated with poor mental health, with no significant interactions with gender. Poor mental health was significantly associated with binge drinking (OR=1.23, 95% CI=1.13-1.33) and with the use of hypnotics/sedatives (OR=1.71, 95% CI=1.53-1.91). House workload showed a direct negative association with binge drinking (OR=0.99, 95% CI=0.98-1.00), while those in households with no children were more likely to be binge drinkers, with no significant interactions with gender. An alternative model had better fitting results for heavy drinking.

CONCLUSION

No gender differences were found in the association of job insecurity with mental health nor with the use of substances among primary providers of household income, emphasising the importance of social roles when assessing differences in mental health among men and women.

Impact of the post-2008 economic crisis on harmful drinking in the Dutch working-age population

BACKGROUND

Studies on the impact of economic crises on alcohol consumption have yielded ambiguous results. Therefore, we studied changes in trends in harmful drinking among Dutch working-age men and women after the post-2008 economic crisis started. We also assessed whether these trend changes differed across age and socioeconomic groups.

METHODS

We used repeated cross-sectional data from the Dutch Health Interview Survey conducted by Statistics Netherlands. Representative samples were independently drawn each month (January, 2004-December, 2013). Our working-age study population consisted of 20,140 men and 22,394 women aged 25-64. For men and women, episodic drinking was defined as drinking ≥6 glasses on one day at least once a week. Chronic drinking was defined as consuming ≥14 glasses/week for women and ≥21 for men. Segmented logistic regression was used to model trend changes separately in men and women.

RESULTS

A downward trend in episodic and chronic drinking before the crisis slowed down after the crisis started. For episodic drinking, we observed a ceasing-of-decline among men aged 35-44/45-54/55-64, compared to a start-of-decline among those aged 25-34 (p-interaction=0.042/0.020/0.047). For chronic drinking, we observed a ceasing-of-decline among women (p=0.023) but not among men in general (p=0.238). Among men, a ceasing-of-decline did occur in those with a high income, but a start-of-decline was found among those with a low income (p-interaction=0.049).

CONCLUSION

In some subgroups of the Dutch working-age population, the downward trend in episodic and chronic drinking ceased after the crisis started. This suggests that the crisis had an upward effect on harmful drinking, but only in specific populations.

[Tobacco and alcohol consumption according to workday in Spain]

OBJECTIVE

To examine the association between smoking and alcohol consumption and the type of working day in the Spanish population

METHODS

Cross-sectional study among employees residing in Spain aged >18 years (N=8,736). We took data from the National Health Survey (2011-2012). Information was collected on the type of working day (morning, afternoon, evening, part-time, reduced hours, and shift-work) and smoking and drinking habits. Demographic characteristics and health- and work-related factors were also taken into account. Adjusted odds ratios (aOR) and 95% confidence intervals (95%CI) were calculated through log-binomial regressions.

RESULTS

Among respondents, 32.1% smoked regularly, especially those working the night shift (43.5%). Moderate alcohol consumption was found in 54.8% of workers and excessive consumption in 1.5%. Most of the moderate and heavy drinkers worked part-time, with 57.6% and 1.8% respectively. The aOR of being a smoker was higher among night workers (OR=1.58; 95% CI: 1.01-2.46). None of the work shifts were significantly associated with alcohol consumption.

CONCLUSIONS

Night shift work was associated with regular smoking. This collective of workers should be monitored closely by occupational health services and regularly undergo programs to control tobacco consumption and smoking-related diseases. Additional research to elucidate the reasons for this association could help to achieve preventive and therapeutic success.

Characteristics and Factors Associated with Problem Drinking in Male Workers

PURPOSE

This study aimed to identify the characteristics and factors related to problem drinking in male workers.

METHODS

This study was conducted using a cross-sectional survey and 232 male workers, who completed self-reported questionnaires addressing alcohol consumption, drinking motives, job stress, supervisor/coworker support, and family support. Multivariate analysis was used to uncover factors associated with problem drinking.

RESULTS

As compared with normal alcohol users, problem drinkers were more likely to smoke and had greater family support and coping motivations, and fewer confirmatory motives. Problem drinking was found to be related to perceived health status (adjusted odds ratio [OR] = 0.78, 95% confidence interval [CI] [0.64, 0.95]), current smoking (adjusted OR = 2.79, 95% CI [1.26, 6.18]), family support (adjusted OR = 2.04, 95% CI [1.23, 3.39]), confirmatory motivation (adjusted OR = 0.60, 95% CI [0.37, 0.96]), and coping (adjusted OR = 1.79, 95% CI [1.04, 3.07]).

CONCLUSIONS

Our findings suggest that any interventions targeting problem drinking among male workers must address smoking cessation, control of stress, and the improvement of drinking subculture in the workplace.
