Physical Activity, Sedentary Behavior, and Cardiorespiratory Fitness in Hazardous and Non-Hazardous Alcohol Consumers

Purpose: To describe physical activity habits, sedentary behavior, and cardiorespiratory fitness levels among alcohol abstainers, hazardous and non-hazardous drinkers. Design: Cross-sectional study with data collected between 2017-19. Setting: Sweden. Subjects: Adults aged 18-65 years (n = 47,559; 59.4% male). Measures: During a routine health assessment, participants answered validated single-item questions regarding: habitual physical activity, structured exercise, and the percentage of time spent sedentary during leisure-time (past 30 days), and completed a 6-minute cycle ergometer test (V02max) to determine cardiorespiratory fitness (CRF). Participants were categorized as alcohol abstainers, non-hazardous drinkers or hazardous drinkers (low/high) based on the Alcohol Use Disorders Identification Test (AUDIT-C) cut-points for men and women. Analysis: Logistic regression models stratified by sex and age. Results: Compared to non-hazardous drinkers, the heaviest drinkers were less physically active (males: OR = 1.38, CI = 1.13-1.67, p = .001; females: OR = 1.41, CI = 1.01-1.97, p = .040) and more sedentary during leisure time (males: OR = 1.94, CI = 1.62-2.32, p = .000; females: OR = 1.62, CI = 1.21-2.16, p = .001). Apart from young females, the heaviest drinkers also did less structured exercise than non-hazardous drinkers (males: OR = 1.22, CI = 1.15-1.51, p = .000; females: OR = 1.43, CI = 1.15-1.78, p = .001). The strongest associations were seen among adults aged 40-65 years (shown here). High-hazardous drinking was associated with low CRF among older males only (OR = 1.19, CI = 1.00-1.41). Conclusion: Middle-aged adults with AUDIT-C scores of ≥6 (women) and ≥7 (men) were less physically active and more sedentary during leisure time and may be appropriate targets for physical activity interventions.

A cross-sectional analysis of alcohol consumption, sex, and the odds of Alzheimer's disease and other dementias in the community-dwelling Canadian population

Background: The prevalence of Alzheimer’s disease (AD) and other dementias is perpetually increasing in Canada and worldwide with the aging baby boomer population. It is, therefore, important to identify risk factors for these major neurocognitive disorders, such as alcohol consumption, to mitigate the future burden on caregivers and the economy. The purpose of this study was to replicate previous research regarding the dose-response relationship between alcohol consumption and the odds of currently having AD or another dementia. The possibility of a sex effect moderating this relationship was also explored. Participants: Data were obtained for respondents to the combined 2015/16 cycles of the Canadian Community Health Survey who were aged 41 years or older at the time of the survey’s conduction (nweighted = 16,715,618). Methods: Logistic regression was used to crossectionally assess the relationship between various time- and frequency-related alcohol consumption exposures to outcome dementia status, while controlling for a number of demographic and risk factor variables. Results: A sex effect was identified for drinking at an average frequency of four to six times per week over the past year (p = 0.019, 95% CI: 0.03, 0.73) where women (ORw = 0.13) were more protected against currently having AD or dementia than men (ORm = 0.89) when compared to alcohol abstainers. Binge drinking two to three times per month (OR = 0.19, p = 0.015, 95% CI: 0.05, 0.73) and more than once per week over the past year (OR = 0.16, p = 0.007, 95% CI: 0.04, 0.61) significantly lessened the odds of currently having AD or dementia when compared against alcohol abstainers. A sex effect was present for those who were classified as very heavy drinkers (♂: 6+ drinks/day, ♀: 4+ drinks/day) over the past week (p = 0.018, 95% CI: 1.14, 39.41) where alcohol was protective against currently having AD or dementia in men (ORm = 0.29) and alcohol was a risk factor for currently having AD or dementia in women (ORw = 2.15) when both were referenced with alcohol abstainers. Conclusions: With the exception of very heavy drinker women, drinking alcohol was associated with a reduced likelihood of currently having AD or dementia and sex effects were identified for drinking at a moderate frequency over the past year and very heavy drinkers. However, these results should be interpreted with caution due to the possibility of selection, sparse data, and abstainer biases as well as misclassification error. The primary implication of this research is to inform future studies that a more thorough exploration of a sex effect influencing the relationship between alcohol consumption and having AD or dementia is warranted.

15-year-old tobacco and alcohol abstainers in a drier generation: Characteristics and lifestyle factors in a Norwegian cross-sectional sample

Aims: Norwegian adolescents currently drink and smoke less on average than previous cohorts. Based on cross-sectional survey data, the individual and familial characteristics of 15-year-old non-users and users of alcohol and tobacco were compared to identify correlates to abstinence. Methods: The survey was approved by the Norwegian Social Science Service. The sample consisted of 3107 adolescents from a 2011 school-based survey, of which 848 (27.3%) did not drink alcohol nor use tobacco. Associations with leisure time activities, risk perceptions, parenting style and social factors were analysed by logistic regression. Results: Most of the non-drinkers were also non-users of tobacco. Abstainers (neither alcohol nor tobacco use) tended to have less unorganized and more hobby-related leisure time activities, higher risk perceptions for smoking, and monitoring or emotionally supportive parents. They more rarely reported close relationships with their best friend and were more likely to report lower occurrences of drinking and smoking among friends or siblings. Conclusions: Differences in perceived parenting styles and a lower degree of unorganized leisure in the abstainer group points to monitoring and closer emotional ties between parents and children as important factors in adolescent abstinence. An implication of these results is that promoting hobby-based activities might be a useful strategy for preventing alcohol and tobacco use in young people.

The association between alcohol abstinence, drinking or binge drinking and drug use: is alcohol abstinence that safe?

Purpose The purpose of this paper is to investigate the association between alcohol abstinence and illicit drug use during early adulthood, and compares abstinence to moderate drinking and binge drinking, regrouped in different frequencies. Design/methodology/approach A total of 5,968 young male adults who completed the questionnaires were selected for the analyses. Alcohol abstinent participants were compared to moderate drinkers (who did not experience binge drinking during the previous 12 months), and casual, monthly, weekly and daily binge drinkers in terms of prevalence of drug use during early adulthood. Findings Alcohol abstinence was associated with higher risks of drug use than moderate drinking (odds ratio (OR)>3) for most of drugs, especially last-stage drugs: crystal meth, solvents, spice and heroin (6.50<OR<13.50). Such findings encourage rethinking prevention among alcohol abstainers who were so far considered at low risk of drug use. Research limitations/implications The main limitations of the study are the fact that it is cross-sectional, gender-blind and focussing on Swiss native who are less vulnerable than migrants. Practical implications High-risk subjects should be identified among young people who do not drink in order to develop specific preventive interventions. Originality/value This study is one of the first that compare alcohol abstinence, moderate drinking and binge drinking. Separate results covering 15 different drugs are presented.
