The association between population drinking and ischemic heart disease mortality in educational groups.

A large number of observational studies have found a J-shaped relationship between alcohol intake and ischemic heart disease (IHD) risk. However, some studies suggest that the alleged cardio-protective effect may be an artifact in the way that the elevated risk for abstainers is due to self-selection on risk factors for IHD. The aim of this paper is to estimate the association between alcohol and IHD-mortality on the basis of aggregate time-series data, where the problem with selection effects is not present. In addition, we will analyze SES-specific mortality to investigate whether there is any socio-economic gradient in the relationship at issue. SES was measured by educational level. We used IHD-mortality in three educational groups as outcome. Per capita alcohol consumption was proxied by Systembolaget's alcohol sales (litres of alcohol 100% per capita 15+). Swedish quarterly data on mortality and alcohol consumption spanned the period 1991Q1-2020Q4. We applied SARIMA time-series analysis. Survey data were used to construct an indicator of heavy SES-specific episodic drinking. The estimated association between per capita consumption and IHD-mortality was positive and statistically significant in the two groups with primary and secondary education, but not in the group with postsecondary education. The association was significantly stronger the lower the educational group. Although the associations were generally stronger for males than for females, these differences were not statistically significant (P > 0.05). Our findings suggest that the detrimental impact of per capita consumption on IHD-mortality was stronger the lower the educational group.

Is the association between alcohol use and sickness absence modified by socioeconomic position? findings from the Stockholm public health cohort.

BACKGROUND: The distribution of sickness absence tends to be socially patterned less is however known about the underlying mechanisms and pathways of the social gradient found in sickness absence. The present study aims to investigate (i) if the risk function between average volume of alcohol consumption and sickness absence is modified by socio-economic position (SEP), and (ii) whether such an effect modification can be attributed to differences in drinking patterns and other risk factors including other lifestyle behaviours, health status, and working conditions. METHODS: The study was based on data from the Stockholm public health cohort 2006, with an analytical sample of 13 855 respondents aged 18-64 years. Self-reported information on occupational class (a measure of SEP), alcohol consumption, other lifestyle behaviour, health and working conditions was collected from the survey. The outcome of long-term (> 14 days) sickness absence between 2006 and 2008 was obtained from national registers. Negative binomial regression was used to estimate the Incidence Rate Ratios (IRR) with 95% confidence intervals (CI). RESULTS: In the initial analyses, heavy drinking manual workers had a 5-fold increased risk of long-term sickness absence compared to non-manual employees who were moderate drinkers, and approximately 60% of the excess risk among heavy drinking manual workers was attributable to an interaction between alcohol use and SEP. Adjusting for working conditions was associated with the largest attenuation of the risk estimate, compared to other lifestyle behaviors and health. In the fully adjusted model, the IRR was further attenuated for the manual workers and the joint effect of SEP and heavy drinking remained in the final model with an attributable proportion of 49%. CONCLUSIONS: Individuals in Sweden with lower levels of SEP appear to be more vulnerable to alcohol consumption in relation to sickness absence, where differences in working conditions explained a large part but not all of the differential vulnerability.

Do early life factors explain the educational differences in early labour market exit? A register-based cohort study.

BACKGROUND: Socioeconomic inequalities in labour market participation are well established. However, we do not fully know what causes these inequalities. The present study aims to examine to what extent factors in childhood and late adolescence can explain educational differences in early labour market exit among older workers. METHODS: All men born in 1951-1953 who underwent conscription examination for the Swedish military in 1969-1973 (n = 145 551) were followed from 50 to 64 years of age regarding early labour market exit (disability pension, long-term sickness absence, long-term unemployment and early old-age retirement with and without income). Early life factors, such as cognitive ability, stress resilience, and parental socioeconomic position, were included. Cox proportional-hazards regressions were used to estimate the association between the level of education and each early labour market exit pathway, including adjustment for early life factors. RESULTS: The lowest educated men had a higher risk of exit through disability pension (HR: 2.72), long-term sickness absence (HR: 2.29), long-term unemployment (HR: 1.45), and early old-age retirement with (HR: 1.29) and without income (HR: 1.55) compared to the highest educated men. Factors from early life explained a large part of the educational differences in disability pension, long-term sickness absence and long-term unemployment but not for early old-age retirement. Important explanatory factors were cognitive ability and stress resilience, whilst cardiorespiratory fitness had negligible impact. CONCLUSIONS: The association between education and early exit due to disability pension, long-term sickness absence and long-term unemployment was to a large part explained by factors from early life. However, this was not seen for early old-age retirement. These results indicate the importance of taking a life-course perspective when examining labour market participation in later working life.

Educational qualification differences and early labor market exit among men: the contribution of labor market marginalization measured across the working life.

BACKGROUND: The present study aims to investigate the association between educational qualification and early labor market exit among men and to examine the contribution of labor market marginalization measured across the working life on this association. METHOD: A register-linked cohort study was conducted including men who completed military service in 1969/70 (born between 1949 and 1951) and were alive at age 55 and not disability pension beneficiaries (n = 40 761). Information on the highest level of educational qualification and the outcome of early exit (disability pension, sickness absence, unemployment, and early old-age pension) was obtained from Swedish nationwide registers between the ages of 55 and 64 years. Labor market marginalization was defined as periods of long-term unemployment and sickness absence over the working life and up to follow-up. Cox regression analyses were used to obtain hazard ratios (HR) with 95% confidence intervals (CI). RESULTS: Low-educated men were more likely to leave the labor force early due to disability pension or sickness absence (HR: 2.48), unemployment (HR: 2.09), and early old-age pension with- (HR:1.25) and without -income (HR: 1.58). Labor market marginalization across the working life explained a large part of the association for the more involuntary early exit routes (disability pensions, sickness absence, unemployment) and explained very little with regards to the more voluntary early exit routes (early old-age pension with and without income). CONCLUSION: Exposure to labor market marginalization across the working life was important in explaining educational differences in early labor market exit due to disability pension or sickness absence and unemployment. This study underscores the importance of identifying and implementing preventive measures in the workplace (e.g. adaptions) to prevent new spells of sickness absence and unemployment, especially among low educated individuals.

Country-Level Heavy Episodic Drinking and Individual-Level Experiences of Harm from Others' Drinking-Related Aggression in 19 European Countries.

INTRODUCTION: There is limited knowledge about how individual experiences of harm from others' drinking are influenced by heavy episodic drinking (HED) at the country level. The present study aimed to assess (1) the association between the country-level prevalence of HED and the risk of experiencing harm from others' drinking-related aggression and (2) if HED at the country level modifies the association between consumption of alcohol per capita (APC) and such harm. METHODS: Outcome data from 32,576 participants from 19 European countries stem from the RARHA SEAS study. Self-reported harm from others' drinking included having been verbally abused, harmed physically, or having serious arguments. Data on country-level drinking patterns were derived from the World Health Organization. Associations between country-level prevalence of monthly HED and experiences of aggression (at least 1 of 3 studied harms) were derived through multilevel models - adjusted for country-level age structure and by including the respondent's own HED patterns as a mediator. RESULTS: A 1% increase in the prevalence of monthly HED was associated with 5% higher odds (odds ratio [OR] 1.05) of experiencing others' alcohol-related aggression among men, and 6% (OR 1.06) among women. The results suggest that the association between APC and harm was stronger in countries with high prevalences of HED, but the modifying effect could not be confirmed. DISCUSSION/CONCLUSION: Harm from others' drinking-related aggression depends not only on individual factors but is also influenced by the drinking patterns of the population. However, the country-level prevalence of HED only explains a small part of the variance of this type of harm.

Changes in the Price of Alcohol and Effect on Youth Drinking and in Different Socio-Economic Groups.

AIMS: Many studies have shown that changes in alcohol prices have a significant effect on total sales. However, few studies have focused on youth, particularly in different socioeconomic groups. This study examined the effect of changes in the price of alcohol on consumption levels and binge drinking among 15 to 16 year old students in Sweden, both overall, among boys and girls, as well as within different socioeconomic groups. METHODS: Data on consumption were retrieved from a representative survey of students aged 15-16, conducted annually between 1989 and 2017. Time series analysis employed an autoregressive integrated moving average model (ARIMA). Two types of price data were used: the official price at the retail stores, and the mean price of the ten cheapest beverages in each category. The mean aggregate annual income per Swedish household was included as a control variable.The variable used to measure the socioeconomic status was the proportion of the ninth-grade students at each school, who had at least one parent with an education higher than upper secondary school. RESULTS: The students' alcohol consumption levels and binge drinking were not significantly affected by price changes during the study period; this was true both for the group as a whole, and among subgroups of boys or girls or of different socioeconomic status. Results were similar regardless of which type of price data variable was used in the analyses. CONCLUSION: Neither average nor minimum price of alcohol had a significant impact on the development of youth drinking in Sweden during the study period.

Educational differences in labor market marginalization among mature-aged working men: the contribution of early health behaviors, previous employment histories, and poor mental health.

BACKGROUND: Social inequalities in labor force participation are well established, but the causes of these inequalities are not fully understood. The present study aims to investigate the association between educational qualification and labor market marginalization (LMM) among mature-aged working men and to examine to what extent the association can be explained by risk factors over the life course. METHOD: The study was based on a cohort of men born between 1949 and 1951 who were examined for Swedish military service in 1969/70 and employed in 2000 (n = 41,685). Data on educational qualification was obtained in 2000 and information on the outcome of LMM (unemployment, sickness absence, and disability pension) was obtained between 2001 and 2008. Information on early health behaviors, cognitive ability, previous employment histories, and mental health was collected from conscription examinations and nationwide registers. RESULTS: Evidence of a graded association between years of education and LMM was found. In the crude model, compared to men with the highest level of education men with less than 12 years of schooling had more than a 2.5-fold increased risk of health-related LMM and more than a 1.5-fold increased risk of non-health-related LMM. Risk factors measured across the life course explained a large part of the association between education and health-related LMM (33-61%) and non-health-related LMM (13-58%). CONCLUSIONS: Educational differences remained regarding LMM among mature-aged workers, even after considering several important risk factors measured across the life course. Previous health problems and disrupted employment histories explained the largest part of the associations.

The Contribution of Alcohol Use, Other Lifestyle Factors and Working Conditions to Socioeconomic Differences in Sickness Absence.

INTRODUCTION: This study investigates how alcohol use contributes to the social gradient in sickness absence. Other factors assessed include lifestyle factors (smoking, physical activity and body mass index), physical and psychosocial working conditions. METHODS: The study used baseline data from the Stockholm public health cohort 2006, with an analytical sample of 17,008 respondents aged 25-64 years. Outcome variables included self-reported short-term (<14 days) and register-based long-term (>14 days) sickness absence. Socioeconomic position (SEP) was measured by occupational class. Alcohol use was measured by average weekly volume and frequency of heavy episodic drinking. Negative binominal regression was used to estimate sex-specific SEP differences in sickness absence, before and after adjusting for alcohol use and the additional explanatory factors. RESULTS: Adjusting for alcohol use attenuated the SEP differences in long-term sickness absence by 20% for men and 14% for women. Alcohol use explained a smaller proportion of the differences in short-term sickness absence. Alcohol use in combination with other lifestyle factors attenuated the SEP differences (20-35%) for both outcomes. Physical working conditions explained more than half of the gradient in long-term sickness absence, whereas psychosocial conditions had greater impact on short-term sickness absence among men. DISCUSSION/CONCLUSION: Alcohol use explains a substantial proportion of the SEP disparities in long-term sickness absence among men. The effect is smaller among women and for short-term sickness absence. Our findings support the notion that physical working conditions constitute the key explanatory variable for SEP differences in long-term sickness absence, but add that psychosocial working conditions have greater impact on the gradient in short-term sickness absence among men.

Social Inequalities in Harmful Drinking and Alcohol-Related Problems Among Swedish Adolescents.

AIMS: The study aims to examine how socio-economic status (SES) among youth is related to binge-drinking and alcohol-related problems using three SES indicators: (i) SES of origin (parental education level), (ii) SES of the school environment (average parental education level at student's school) and (iii) SES of destination (academic orientation). METHODS: Cross-sectional data on upper secondary students (n= 4448) in Sweden. Multilevel logistic and negative binomial regression were used to estimate the relationship between each SES indicator and binge-drinking and alcohol-related problems, respectively. RESULTS: Only SES of destination was significantly associated with binge-drinking, with higher odds for students in vocational programmes (OR= 1.42, 95% CI= 1.13-1.80). For the second outcome, SES of destination (rr=1.25; 95%CI=1.08-1.45) and SES of the school environment (rr=1.19, 95% CI=1.02-1.39) indicated more alcohol-related problems in vocational programmes and in schools with lower-educated parents. After adjustment for drinking patterns, the relationship remained for SES of the school environment, but became non-significant for SES of destination. CONCLUSION: Our results suggest that the SES gradient among youth is stronger for alcohol-related problems than for harmful drinking. By only focusing on SES differences in harmful alcohol use, researchers may underestimate the social inequalities in adverse alcohol-related outcomes among young people. Our findings also support the notion that the environment young people find themselves in matters for social inequalities in alcohol-related harm.

Fathers' Alcohol Consumption and Long-Term Risk for Mortality in Offspring.

AIM: This study examined associations between fathers' alcohol consumption and risk for total and cause-specific mortality in offspring. SHORT SUMMARY: We examined the associations between fathers' alcohol consumption and total and cause-specific mortality in adult offspring. Fathers' alcohol consumption was associated with increased risk of alcohol-related mortality in offspring. The association appeared to be weaker for causes of death in which alcohol plays a smaller, or less direct, role. METHODS: Data on fathers' alcohol consumption, and offspring's risky use of alcohol, smoking, mental health and contact with police/childcare authorities were collected among 46,284 men (sons) aged 18-20 years, during conscription for compulsory military training in 1969/70. Data on offspring mortality were obtained from the National Cause of Death register, 1971-2008. The mortality outcomes included total mortality, alcohol-related causes of death and violent causes of death (categorized into suicides vs violent/external causes excluding suicides). RESULTS: Compared to sons whose fathers never used alcohol, the risk for total and alcohol-related mortality among sons increased with the father's consumption level. The risk of violent death was significantly elevated among sons whose fathers drank alcohol occasionally or often, but the risk of suicide increased in the highest consumption category only. After adjustment for covariates, the results remained for alcohol-related mortality whereas they were significantly attenuated, or disappeared, for total mortality, violent death and suicide. CONCLUSIONS: Fathers' alcohol consumption is associated with increased risk of alcohol-related mortality in the offspring. Alcohol use among fathers also increases the offspring's risk of later total mortality, suicide and violent death, but these associations appear to be mediated or confounded by factors related to parental drinking and/or adverse childhood psychosocial circumstances.

More Drinking, More Problems-Stable Association Between Alcohol Consumption and Harm Among Swedish Youth 1995-2012.

AIMS: Alcohol consumption among Swedish youth increased during the 1990s. In the following decade, levels declined coinciding with a reduction in the prevalence of self-reported alcohol-related harm. We examine how the trend in self-reported alcohol-related problems among young Swedish alcohol consumers has followed the trend in alcohol consumption during 1995-2012, and test whether the strength of the association between self-reported alcohol consumption and alcohol-related problems within individuals is inversely proportional to the overall level of consumption among youth. METHODS: The study was based on a representative survey on alcohol and drug habits among ninth-year students, consisting of current alcohol consumers (n = 68 863), 1995-2012. Negative binominal regression models were used to estimate the relationship between three consumption variables (average volume of consumption, binge drinking and heavy drinking) and self-reported alcohol-related problems. RESULTS: The prevalence of binge drinking showed a greater association with self-reported alcohol-related problems than did overall mean consumption. No noticeable variation in the strength of the individual-level alcohol and harm relationship was found over the study period. We found no significant interaction between the individual alcohol use measures and overall mean youth consumption. CONCLUSION: We found no signs of normalization; on the contrary, young alcohol consumers suffer about the same number of self-reported negative consequences from their drinking, regardless of the level of overall youth consumption. The study also suggests that binge drinking rather than overall consumption is the main factor that influences the development of self-reported problems experienced among young alcohol consumers. SHORT SUMMARY: Young alcohol consumers suffer about the same number of self-reported negative consequences from their drinking, regardless of the level of overall mean consumption in the youth population. Binge drinking consumption appears to be the main factor influencing the development of self-reported alcohol-related problems among young alcohol consumers.

Socioeconomic Disparities in Alcohol-Related Mortality in Sweden, 1991-2006: A Register-Based Follow-Up Study.

AIM: To examine whether apparent stability of overall alcohol-related mortality in Sweden during a period when traditionally strict alcohol policies went through a series of liberalizations and overall alcohol mortality remained stable, concealed a heterogeneity across socioeconomic groups (defined by educational level); and whether an increase occurred in the contribution of alcohol-related mortality to overall mortality differentials. METHODS: Drawing on cause of death data linked to census records for the period 1991-2006, we computed annual age-standardized and sex-specific rates of alcohol-related mortality for groups with low, intermediate and high education. RESULTS: Alcohol-related mortality was considerably higher in lower educational groups for both men and women. For men, the trends in alcohol-related mortality were roughly stable for all education groups, and there were no signs of increasing inequalities by education. For women, alcohol-related mortality increased significantly for the low-education group whereas the two higher education groups showed no significant time trends, thus resulting in a widened educational gap in alcohol mortality for women. Alcohol's contribution to the overall mortality differentials declined for men and was basically unchanged for women. CONCLUSIONS: The findings provide only partial support to the hypothesis that the liberalizations of Swedish alcohol policy have been followed by a general increase in socioeconomic disparities in alcohol-related mortality.

Changes in the relationship between volume of consumption and alcohol-related problems in Sweden during 1979-2003.

AIMS: The aim of the study was to investigate (i) whether the strength of the relationship between self-reported volume of consumption and alcohol-related problems has become weaker in Sweden, and (ii) whether such a change can be related to temporal changes in drinking patterns or to changes in the distribution of consumption and related problems in the population. METHODS: Three cross-sectional general population surveys conducted in Sweden in 1979, 1995 and 2003 yielded data on 5650 Swedish adults aged 18-69 years. The relationship between self-reported volume of consumption and self-reported alcohol-related problems was estimated using Poisson regression models. Analyses of drinking patterns focused on changes in frequency of drinking, volume per occasion and frequency of drinking to intoxication. Lorenz curves were used to analyse the distributions of consumption and alcohol-related problems. RESULTS: Poisson regression estimates revealed that the relationship between volume of consumption and alcohol-related problems became weaker over time; a 10% per cent change in self-reported volume of consumption was associated with a smaller per cent change in the number of experienced problems in 2003 (5%) compared with 1995 (6%) and 1979 (7%). This change was not related to a hypothesized general shift towards a more southern European style of drinking, as no such tendency was found. CONCLUSION: The changed relationship appears to be a reflection of a redistribution of consumption and alcohol-related problems in the population, such that a larger share of all consumption and related problems occurs among light or moderate drinkers in 2003 compared with 1979.

School pressure and psychosomatic complaints among Swedish adolescents: does physical activity play a buffering role?

Background: School pressure is a significant stressor in the lives of adolescents, recognised to be associated with psychosomatic complaints. Therefore, the exploration of potential buffering factors is a relevant task. This study aimed to examine the association between school pressure and psychosomatic complaints and the potentially moderating role of physical activity in a Swedish national sample of adolescents. Methods: Data were derived from the 2017/2018 Swedish Health Behaviour in School-aged Children (HBSC) survey, involving 3,745 participants aged 11-15 years. School pressure and physical activity were measured using single items. Psychosomatic complaints were assessed through an additive index based on the frequency of eight complaints. Covariates included gender, grade, and family affluence. Results: Linear regression analyses demonstrated a positive graded association between school pressure and psychosomatic complaints, while an inversely graded association was observed between physical activity and psychosomatic complaints. Physical activity did, however, not moderate the link between school pressure and psychosomatic complaints. Conclusion: Even though physical activity did not serve as a buffer, the direct effects of school pressure and physical activity on psychosomatic complaints suggest that supporting young people in managing school demands and promoting their engagement in physical activities could be effective measures in alleviating psychosomatic complaints.

Co-Occurring Alcohol Misuse and Criminal Offending in Adolescence: Is It a Matter of Similarity, Severity, or Accumulation of Risk Factors?

OBJECTIVE: Alcohol misuse and criminal offending often co-occur, and although previous studies indicate an overlap in risk factors, this evidence originates from studies focusing on either alcohol misuse or criminal offending. Co-occurrence might also stem from the severity or accumulation of risk factors. The aim of the following study was to examine whether risk factors for developing co-occurring alcohol misuse and criminal offending in adolescence are similar or unique, and to examine whether risk factors are more severe or accumulative compared with alcohol misuse only and criminal offending only. METHOD: Data were used from the prospective longitudinal project Futura01, consisting of 4,013 randomly selected adolescents in Sweden (males: n = 1,798). Outcomes and a wide variety of risk factors were measured by self-report at two time points. Logistic regression analysis was carried out on groups of (a) no behavior (reference), (b) alcohol misuse only, (c) criminal offending only, and (d) co-occurring behaviors. RESULTS: The findings indicated that similar factors predicted co-occurring behaviors for alcohol misuse only and criminal offending only. Regarding severity, only more severe sensation seeking was associated with co-occurring behaviors compared with alcohol misuse and criminal offending only. Instead, an accumulation of risks (i.e., more risk factors present) increased the probability of co-occurring behaviors compared with alcohol misuse only and criminal offending only. CONCLUSIONS: The results indicated that the risk factors for developing co-occurring alcohol misuse and criminal offending in adolescence are similar rather than unique and that it is the accumulation of the risk factors, as opposed to their severity, that is associated with co-occurring behaviors when comparing with alcohol misuse and criminal offending only.

Predictors of One-Year Persistence of Harm From a Known Person's Drinking: Findings From a Longitudinal Population-Based Study in Sweden.

OBJECTIVE: Few studies have investigated the persistence over time of experiences of harm from a known person's drinking. The aim of this study was to describe 1-year persistence and investigate its predictors at baseline. Potential predictors included the harmed person's sociodemographic factors, their own drinking habits, their relationship to the person causing harm, and the type of negative experience. METHOD: The sample included respondents who reported experiencing harm from a known person's drinking in a general population survey in 2013 and participated in a follow-up survey in 2014 (n = 1,203). One-year persistence of experienced harm was defined as reporting any harm in both surveys. We investigated potential baseline predictors of persistence by estimating relative risks and 95% confidence intervals through modified binary Poisson regression analyses with robust error variance. RESULTS: One-year persistence of experiencing any type of harm from a known person's drinking was seen in 52.5% of those reporting harm at baseline and was higher among women (56.7%) than men (43.3%). Reporting harm from a partner, parent, or other household member significantly predicted 1-year persistence, as did severity of overall perceived harm at baseline. CONCLUSIONS: In Sweden, 1-year persistence of experienced harm from a known person's drinking is common in most individuals. The risk of experiencing such harm is higher among women, when harm occurs within close relationships, and when it is experienced as severe at baseline. Support to individuals in these situations is crucial.

Is youth violence temporally related to alcohol? A time-series analysis of binge drinking, youth violence and total alcohol consumption in Sweden.

AIMS: The purpose of this study is to investigate the temporal association between violence and binge drinking among Swedish youth. Two time periods are analysed, the first one representing the full observation period 1971-2009 and the second one representing a confined period 1971-2000. Furthermore, the association between population drinking and binge drinking among youths is also investigated with regards to the two time periods. METHODS: ARIMA modelling was applied in order to estimate these associations. RESULTS: Based on the confined time period (1971-2000), analyses revealed that four out of six estimates (two where borderline) of the association between binge drinking and violence (self-reported as well as convictions for assaults) were positive and statistically significant. However, most estimates became non-significant when the full study period (1971-2009) was analysed. The analyses of the relationship between total consumption and youth binge drinking revealed that binge drinking among military conscripts and boys was affected by changes in total consumption during the shorter confined study period. These associations became non-significant when the full study period was included in the models. CONCLUSIONS: (a) there was a positive relationship between violence and binge drinking among Swedish youth at the aggregated level, but mainly with regards to the shorter study period, (b) changes in per capita alcohol consumption were associated with binge drinking among young men and this was more evident for the shorter study period and (c) there was empirical evidence for the idea that these associations became weaker or non-existent after the year 2000.

Using repeated measures to study the contribution of alcohol consumption and smoking to the social gradient in all-cause mortality: Results from the Stockholm Public Health Cohort.

INTRODUCTION: The social gradient in consumption behaviours has been suggested to partly explain health inequalities. The majority of previous studies have only included baseline measurements and not considered potential changes in behaviours over time. The study aimed to investigate the contribution of alcohol consumption and smoking to the social gradient in mortality and to assess whether the use of repeated measurements results in larger attenuations of the main association compared to using single baseline assessments. METHODS: Longitudinal survey data from the population-based Stockholm Public Health Cohort from 2006 to 2014 was linked to register data on mortality until 2018 for 13,688 individuals and analysed through Cox regression. RESULTS: Low socioeconomic position (SEP) was associated with increased mortality compared with high SEP; hazard ratios 1.56 (95% CI 1.30-1.88) for occupational status and 1.77 (95% CI 1.49-2.11) for education, after adjustment for demographic characteristics. Using repeated measurements, alcohol consumption and smoking explained 44% of the association between occupational status and all-cause mortality. Comparing repeated and baseline measures, the percentage attenuation due to alcohol consumption increased from 11% to 18%, whereas it remained similar for smoking (25-23%). DISCUSSION AND CONCLUSIONS: Smoking and alcohol consumption explained a large part of the association between SEP and mortality. Comparing results from time-fixed and time-varying models, there was an increase in overall percentage attenuation that was mainly due to the increased proportion explained by alcohol consumption. Repeated measurements provide a better estimation of the contribution of alcohol consumption, but not smoking, for the association between SEP and mortality.

Self-reported alcohol consumption and the risk of alcohol-related problems: a comparative risk-curve analysis of the 3 Baltic countries, Sweden, and Italy.

BACKGROUND: Previous research has suggested a positive risk-relationship between volume of consumption and adverse behavioral and social consequences of drinking. However, because the risk-relationship may be modified by factors such as pattern of drinking, attributes of social drinking contexts, and drunken comportment, the shape of the risk-function appear to be contingent upon the larger cultural context of drinking. METHODS: In this article, I use graphical risk-curve analyses and model estimations to assess how the risk of experiencing alcohol-related problems is associated with self-reported volume of alcohol consumption in the 3 Baltic countries (Estonia, Latvia, and Lithuania) as well as Sweden and Italy. The analysis utilized data from 2 general population surveys (including Sweden plus Italy and the Baltic countries, respectively) with approximately 1,000 respondents from each country. RESULTS: The risk-curves for the 3 Baltic countries and Sweden were fairly parallel and clearly steeper than that for Italy. In the logistic regression models, the country-specific Baltic estimates were not entirely homogenous; for Estonia and Latvia, the estimates were similar to that for Sweden and significantly larger than that for Italy, whereas the estimate for Lithuania did not differ significantly from that for Italy. However, the negative binominal regression models suggested that increasing volume of consumption is associated with the risk of experiencing a larger number of different problems in all 3 Baltic countries and Sweden than in Italy. Overall, the result thus suggests that there is a significant relationship between volume of consumption and risk of experiencing alcohol-related problems in all countries but that the relationship generally is stronger in the Baltic countries and Sweden than in Italy. CONCLUSIONS: The results were largely in line with the hypothesis of a European north to south gradient in the strength of the risk-relationship, but also add that most Baltic countries may be placed alongside the Nordic countries in this context. Because only volume of consumption is considered, the results cannot be used to specify which factors and mechanisms that actually modify the shape of the risk-function in each culture.

To drink or not to drink: A study of the association between rates of non-drinkers and per drinker mean alcohol consumption in the Swedish general population.

INTRODUCTION: Understanding how the mean consumption per drinker and rates of non-drinking interplay to form overall per capita alcohol consumption is imperative for our understanding of population drinking. The aim of the present study is to examine the association between rates of non-drinkers and per drinker mean alcohol consumption in the Swedish adult population and for different percentiles of drinkers. METHODS: Data came from a monthly telephone survey of drinking habits in the Swedish adult population between 2002 and 2013. Alcohol consumption and non-drinking during the last 30 days were measured by beverage-specific quantity-frequency questions. Regression models estimated the association between the rate of non-drinkers and per drinker volume on annual data. Auto-regressive integrated moving average time-series models estimated the association on monthly data. RESULTS: A significant (P < 0.01) negative association (-0.849) was found between the rate of non-drinkers and per drinker mean volume on annual data. A unit increase in non-drinking was associated with a decline of 0.85 cl of pure alcohol among drinkers. This finding was mirrored across all percentiles of consumption. The semi-log models found that a 1% unit increase in the rate of non-drinkers was followed by a 2% reduction in per drinker mean consumption. Auto-regressive integrated moving average time-series models verified these results. DISCUSSION AND CONCLUSIONS: There is a significant association between the proportion of non-drinkers and the amount of drinking among drinkers. The theory of collectivity of drinking cultures should also include the non-drinking part of the population.
