Delphi method applicability in drug foresight.

BACKGROUND: The aim of the current study was to assess the accuracy of expert predictions, which were derived using a Delphi panel foresight study between 2009 and 2011, on a variety of drug-related topics in Finland in 2020. METHODS: The material used to evaluate the accuracy of the predictions consists of published reports on statistics, survey results, official register data, wastewater analyses and official documents. Whenever possible, we used multiple information sources to ascertain possible changes related to the predictions. RESULTS: Between 2009 and 2011, the majority - but not all - of the experts accurately predicted an increase in drug use. Indeed, more people experimented with or used drugs, and more drug residues were found in wastewater monitoring. The experts also correctly predicted an increase in population-level approval of drug use, but this development has been rather slow. Contrary to predictions, there was no marked increase in the use of new synthetic drugs. However, the misuse of buprenorphine increased during the 2010s. In the drug market, unit prices were surprisingly stable over the ten-year period. There were no changes in legislation related to the legal status of drugs, as was foreseen by the experts. However, enforcement moved in the direction foreseen by the experts: more lenient measures have been taken against users. Drug care system reforms favored a combination of mental health and addiction care units between 2009 and 2011, and 2020, as foreseen by the experts. CONCLUSIONS: It seems to have been easier for the experts to foresee the continuation of existing trends, e.g., increasing use of drugs or widening approval of drugs, than to predict possible changes in the popularity of distinct groups of drugs such as new psychoactive substances (NPS). Even armed with the prediction that drug imports and wholesale would increasingly fall into the domain of organized crime, this undesirable development could not be stopped. Expert disagreement can also be seen as a valuable indication of uncertainty regarding the future. Foresight related to drug-related issues can produce relatively accurate and realistic views of the future at least up to ten years ahead.

Drinking in the home: What does it entail for younger and older Finns?

INTRODUCTION: Studies about drinking in homes are scarce despite the growing importance of the phenomenon. We examined how often different age groups in Finland drink-overall or to intoxication-in their own homes without company beyond the family and in their own or other people's homes with other company, compared to other settings, and on what days and hours of the week this occurs. METHODS: A general population survey carried out in 2016 with event-level data (n = 7124 occasions by 1955 respondents). Key measurements included location, drinking company, amount of alcohol drunk and time of the week. RESULTS: Drinking occasions in which alcohol was drunk at home without visitors made up 74% of all occasions and 73% of all intoxication occasions among people aged 60-79 years and 25% and 5% among 15- to 29-year-olds, respectively. The share of 'with company' occasions in somebody's home varied less by age. Occasions with pre/post drinking in homes and drinking occasions lasting until late at night were seen most often among 15- to 29-year-olds. DISCUSSION AND CONCLUSIONS: The important aspects of home drinking vary greatly by age group and depending on what risk or type of consequence is considered. For older people and for chronic harm, the key aspect is drinking at home without company beyond the family. The more important aspect for younger people and acute harm is pre- and post-drinking in homes before or after going to bars or nightclubs, which results in long evenings with large amounts of alcohol consumed.

Who buys non-alcoholic beer in Finland? Sociodemographic characteristics and associations with regular beer purchases.

BACKGROUND: The consumption of non-alcoholic beer and other non-alcoholic and low-alcohol beverages has grown significantly in recent years. Due to a lack of suitable datasets, there have been few studies conducted on the forerunners of the non-alcoholic beer consumption trend. This study examined the associations of sociodemographic characteristics with non-alcoholic beer purchase, and of non-alcoholic beer purchases with regular beer purchases. METHODS: The data consisted of longitudinal individual purchases of non-alcoholic and regular beer from grocery stores in 2017 and 2018. The study participants were loyalty cardholders from the largest food retailer in Finland (n = 47,066). The level of education, household income and occupational status were analyzed as determinants of non-alcoholic beer purchase using logistic regression models. The changes in the regular and non-alcoholic beer purchases from 2017 to 2018 and the distributions of non-alcoholic beer purchase by regular beer purchase, by gender and by age were described. RESULTS: Between 2017 and 2018, the total volume of non-alcoholic beer purchases increased from 2.3% to 3.7% of the total volume of all beer purchases. Men and older people purchased non-alcoholic beer more often than women and younger people did. Non-alcoholic beer purchases were most common among the highly educated and high-income consumers. Non-alcoholic beer purchases were most prevalent in the groups with the highest volumes of regular beer purchase. CONCLUSIONS: Educated and affluent consumers have been the forerunners of non-alcoholic beer consumption in Finland. In order to promote the substitution of regular beer with non-alcoholic beer the shift towards lower-strength beverages should be facilitated across social strata.

Gambling Among Underage Alcohol Users Between 2008 and 2019: A National Cross-Sectional Study Among Finnish Adolescents.

PURPOSE: The aim of this study is to examine trends in the relationship between gambling, alcohol use, and drunkenness between genders in Finland from 2008 through 2019. METHODS: Data were based on six waves (2008-2009, 2010-2011, 2013, 2015, 2017, 2019) of a national cross-sectional School Health Promotion Study. The survey was conducted during a school day among eighth graders (14-15 years old) and ninth graders (15-16 years old) in Finland. The changes in gambling frequency among boys and girls were studied (regular gambling: at least once a week; occasional gambling: 2-3 times a month to less than once a month; no gambling during the previous year), alcohol use (at least once a month), and drunkenness (at least once a month). RESULTS: The prevalence of adolescent gambling was more than halved between 2008 and 2019. However, the difference between the adolescents with the most favorable outcome (those who were not gambling and used alcohol or were getting drunk less often than once a month) and the adolescents with the least favorable outcome (boys who gambled, used alcohol, or were getting drunk; girls who were gambling regularly and getting drunk or gambling occasionally, using alcohol, and getting drunk) was larger in 2019 than in 2008. DISCUSSION: These larger differences between adolescents indicate that there has been a polarization of problems between adolescents, and for some individuals, problems are clustering. There is a strong case to be made for protecting adolescents from these risk behaviors and their adverse consequences on multiple levels.

Changes in alcohol purchases from grocery stores after authorising the sale of stronger beverages: The case of the Finnish alcohol legislation reform in 2018.

Aims: The Finnish alcohol law was reformed in January 2018. The availability of alcoholic beverages in grocery stores increased as the legal limit for retail sales of alcoholic drinks was raised from 4.7% to 5.5% alcohol, and the requirement of production by fermentation was abolished. We analysed how the inclusion of strong beers, ciders, and ready-to-drink beverages in grocery stores was reflected in alcohol purchases, and how these changes differed by age, sex, level of education and household income. Design: The study sample included 47,066 loyalty card holders from the largest food retailer in Finland. The data consisted of longitudinal, individual-level information on alcohol purchases from grocery stores, covering the time period between 1 January 2017 and 31 December 2018. The volumes of absolute alcohol during a calendar year from beers, ciders, ready-to-drink beverages, and in total, were calculated. Alcohol purchases in 2017 and 2018 were compared. Results: There was no overall change in the total alcohol (0.04 [95% CI -0.03, 0.11] litres/year) or beer purchases (-0.05 [95% CI -0.11, 0.02] litres/year). Purchases of ready-to-drink beverages increased by 0.10 [95% CI 0.09, 0.11] litres/year (+ 84%). Total alcohol purchases increased in the three highest income groups, whereas they decreased in the two lowest groups (p for the interaction < 0.0001). Conclusions: The increased purchases of alcohol as ready-to-drink beverages were, on the average, compensated for by a decrease in purchases of other alcoholic beverages. Higher prices probably limited the purchases among lower income groups and younger consumers, while the increase was sharper in higher income groups.

Domestication of drinking: a survey study of changes in types of drinking occasions during periods of increasing and decreasing alcohol consumption in the 2000s in Finland.

BACKGROUND AND AIMS: In Finland, per-capita alcohol consumption increased in the early 2000s and decreased after 2007. Our aim was to determine how these changes originated from changes in drinking practices. DESIGN: Repeated cross-sectional general-population surveys. SETTING: Finland in 2000, 2008 and 2016. PARTICIPANTS: Finnish residents aged 15-69 years (n = 6703, response rate 59-78%). MEASUREMENTS: Event-level data on drinking occasions (n = 21 097). Types of drinking occasions (drinking practices) were identified with latent class analysis using occasion characteristics. The aggregated volume of consumption and intoxication occasions were decomposed into contributions from drinking practice classes and years. FINDINGS: Nine drinking occasion types were identified: three at home without company other than family (51% of occasions in 2016), three socializing occasions in different places and with different company (33%) and three party occasion types (16%). Both the frequency of drinking occasion types and the occasion type-specific amounts of alcohol consumed contributed to aggregate-level changes in alcohol use. Drinking at home without external company (with family only; for men, also alone) contributed most to the increase in alcohol use before 2008. Big parties in homes and bars became less common in the 2000s, contributing most to the decline in drinking after 2008. CONCLUSIONS: The rise in per-capita alcohol consumption in Finland in the early 2000s appears to have been linked mainly to an increase in lighter drinking occasions at home without external company. The fall in per-capita drinking after 2007 was linked mainly to a decrease in big parties in homes and in licensed premises. Changes in drinking frequency and the amounts of alcohol consumed per occasion changed in the same direction as alcohol affordability.

Factors associated with non-medical use of prescription drugs among individuals with a legitimate prescription for medical purposes: A population-based study.

Background: Psychoactive prescription drugs are known to have abuse potential. This study was aimed at studying the non-medical use of prescription drugs (NMUPD) among individuals with prescriptions for anxiolytics, sedatives, or strong analgesics. We examined the association of socio-demographics, binge drinking, the number of drug prescriptions, and drug types prescribed for medical purposes with NMUPD among the general Finnish population. Methods: Data were derived from population-based (ages 15-69 years) Drug Surveys conducted in Finland in 2006, 2010, and 2014. The response rates varied between 48% and 55%. Individuals with prescriptions for one or more prescription drugs in the last 12 months were included (n = 1,602) and divided into three groups: medical use only, NMUPD, and NMUPD with illicit drug use (ILLICIT USE). Multinomial logistic regression was used. Results: Among individuals with a prescription for at least one prescription drug, 5.7% reported NMUPD. Living alone and being outside the labour force were associated with NMUPD. Younger age, living in a large city, living alone, and unemployment were associated with ILLICIT USE. Frequent binge drinking and a high number of drug prescriptions were associated with both NMUPD and ILLICIT USE. Those reporting ILLICIT USE were more likely to have a prescription for sedatives. Conclusions: Although NMUPD is on a rather low level among those who have a prescription for legitimate purposes, having multiple prescriptions increased the likelihood of NMUPD. Low socio-economic position and binge drinking are associated with NMUPD and this should be taken into account when planning interventions and preventive actions.

Gambling Among Finnish 14-16-Year-Old Adolescents Before (2008-2009), During (2010-2011), and After (2013-2017) Setting the Legal Age Limit of 18 for Gambling and the Role of Socio-Economic Status.

Legislation prohibiting minors from engaging in gambling is a gambling policy measure set to protect adolescents from the harmful effects of gambling. The Finnish gambling system is based on a state monopoly, regulated by the Lotteries Act. After an amendment to the Lotteries Act, the new minimum legal gambling age was raised to 18 years old between 2010 and 2011. The main purpose of this study was to discover how the amendment to the act altered adolescents' gambling (14-16-year-olds) and to examine whether the amendment decreased socio-economic differences. Adolescents gambling was studied before (2008-2009), during (2010-2011), and after (2013-2017) the age limit of gambling was raised in Finland. The study based on five waves (2008-2009, 2010-2011, 2013, 2015, 2017) of the national repeated cross-sectional School Health Promotion Study. Cross-tabulations where gambling was studied by study year and socio-economic status (SES) were formulated, and the statistical differences were studied by using χ2-tests. Percentage change in gambling frequency was also examined by study year and SES. Study years were analyzed separately to model the weekly gambling via logistic regression models. Adolescent gambling significantly decreased over time. It appears that raising the legal gambling age had a permanent effect on under-aged gambling. However, differences in gambling by adolescents' family's SES increased during the study period, indicating widening inequalities in gambling among adolescents. Diminishing inequalities in adolescent gambling is likely to require both societal action and consensus on adolescent gambling being a significant social and public health concern.

How Are All Drinking Occasions, Intoxication Occasions, and All Alcohol Consumed Distributed Across Different Drinking Occasion Types? A Typology of Drinking Occasions in Finland.

OBJECTIVE: To understand the contexts and characteristics of drinking occasions, we typologized drinking occasions and examined how different aspects of drinking vary in them and what part of population-level drinking and intoxication occasions each covers. METHOD: A Finnish general population survey in 2016 (n = 2,285) with event-level data on drinking occasions (n = 6,697) was used. Occasion types were identified by latent class analysis. The characteristics of the drinking occasions were location, purpose, company, timing, duration, the amounts and beverages drunk, and estimated blood alcohol concentration (eBAC). RESULTS: Eight drinking occasion classes were identified. The three most common ones were all light drinking occasions at home, with the company varying. Five of the eight types were about socializing with people beyond the family. The heaviest drinking occasion type, "big party nights," had an average eBAC of .12%, which seemed to be connected to the long duration of these occasions. The most important contributors to total population-level intoxication occasions were "big party nights" and "at home with the family" occasions (accounting for 30% and 20%, respectively). In terms of contributions to the population's total alcohol consumption, the order of these classes was reversed (19% and 26%, respectively). Drinking at home with no visitors covered 40% of all the alcohol drunk in Finland. Different types of occasions varied little in beverage type composition. CONCLUSIONS: For acute harm, "big party nights" are important to consider because of the prevalence of intoxication, whereas for chronic harm, drinking at home without visitors is even more important to consider.

Social disadvantage and gambling severity: a population-based study with register-linkage.

BACKGROUND: Studies have found an association between problem gambling and poverty. However, there is relatively little research on social inequalities and problem gambling using population representative data. METHODS: A population-representative self-report web-based and postal survey with register-based linkage was conducted in the three geographical areas of Finland. Participants (n = 7186, aged 18 or older) were randomly selected from the population register. Sociodemographic factors and social welfare benefits were studied among gambling groups and their statistical difference were examined by χ2 test. Seven logistic regression models were calculated, where unemployment, social security benefits and low income were treated as dependent variables and where sex, age, family structure and education were controlled as covariates. The results were presented as odds ratios (OR) with 95% confidence intervals (CIs). RESULTS: Problem and at-risk gambling (ARG) was more common among people who were unemployed [PG: χ2=6.4 (1), P < 0.01, ARG: χ2=12.4 (1), P < 0.001] or had received social security benefits [PG: χ2=41.6 (1), P < 0.001, ARG: χ2=22.9 (1), P < 0.001]. The OR for problem gambling was high as 5.6 (CI: 3.22-9.61) among respondents who had received social assistance even when covariates were taking into count. Almost a third of those experiencing problem or at-risk gambling received at least one form of social security benefit. CONCLUSIONS: The most important task of gambling policy should be reducing gambling-related harms and diminishing social inequality. However, even in government organized system where gambling profits are used for common good, profits come from the most socially disadvantaged people thereby exacerbating inequality.

Alcoholic beverage preferences among teenagers in Finland before and after the 2018 alcohol law change.

AIMS: The alcohol law change in Finland in the beginning of 2018 was forecast to shift alcohol sales from alcohol monopoly stores to grocery stores. The trend of declining adolescent alcohol use was predicted to end. This study aimed to provide a more detailed view on under-age drinking change through analysing alcoholic beverage use preferences among 14 and 16 year olds in Finland from 2017 to 2019. METHODS: Nationally representative surveys of adolescent health behaviours in Finland from 2017 (n = 2451) and 2019 (n = 2119) among 14 and 16 year olds were analysed using cross-tabulations and logistic regression modelling. Beverage data were coded from an open-ended question concerning the latest drinking occasion. RESULTS: The proportion of 14 and 16-year-old girls reporting drinking alcohol was 41% in 2017 and 45% in 2019. The corresponding proportions among boys were 39% in 2017 and 43% in 2019. The share of alcohol consumed in the form of beer, alcopops and cider increased among girls from 55% to 75%, but the apparent increase among boys from 69% to 76% was not statistically significant. The only beverage type category that increased in popularity from the year 2017 to 2019 was alcopops. CONCLUSIONS: The law change bringing strong alcopops, beer and cider into grocery stores increased their consumption - especially among the under-aged. Comprehensive measures including taxation, restrictions on advertising and sales affecting the population total consumption are also likely to remain the keys to reducing alcohol consumption among adolescents. In addition, effective age-limit control and sanctions against neglecting age-restriction enforcement are needed.

Factors predicting satisfaction in outpatient substance abuse treatment: a prospective follow-up study.

BACKGROUND: While treatment satisfaction has been associated with better outcomes in substance abuse treatment, there is an obvious need for a more profound understanding of what predicts client's satisfaction with treatment. This study elucidates factors relevant to treatment outcome measured at follow-up in terms of satisfaction with the treatment received. METHODS: The research was implemented as a multisite study in outpatient clinics (N = 7) in southern and western Finland. Data consists of therapists (N = 33) and their clients (N = 327). Each consenting client beginning a treatment period was accepted as a research subject and all therapists at the clinics in question participated. The study was conducted as part of the clinic's normal activity. Clients were allocated to therapists according to a randomization list drawn up in advance. Apart from the randomisation and the completion of questionnaires, it did not interfere with the progress of treatment. Follow-up lasted 6 months. Multiple Classification Analysis (MCA) was used through combinations of variables organized by content, e.g. client demographics, previous substance use, therapist's characteristics and client's expectations. The analyses were based in part on conventional statistical testing (t -test, χ2-test, ANOVA). RESULTS: Among 37 independent variables few were statistically significant in the final model. The results suggest that high treatment expectations at baseline are a strong predictor of satisfaction at follow-up. Also, previous substance use predicted treatment satisfaction; people using multiple substances were less satisfied than those taking only one substance. Stronger predictors reduced the statistical significance of those independent variables that were statistically significant in the first analyses. Therefore, therapist's role in recovery and readiness to change should be also seen as antecedents to treatment satisfaction. CONCLUSIONS: It seems that treatment expectations are fulfilled among those participating in follow-up. Yet many are lost during treatment and by follow-up. Service users have experiential knowledge that differs from professionals' and policymakers' knowledge. It is clinically relevant to understand what factors affect client's satisfaction. Hence, it is possible to identify the population whose treatment should receive the most attention, how the client's experience, their commitment to treatment, and treatment effectiveness could be improved.

Change and continuity in Finnish drinking in the 21st century.

Aim: Alcohol consumption and policy in Finland have undergone a variety of changes in the two last decades. In several cases, trends in both consumption and policy have shifted direction when moving from the first decade of the 21st century to the second one. The aim of the overview is to summarise the trends. Data: The overview draws on results primarily from the cross-sectional Finnish Drinking Habits Survey (FDHS) in 2000, 2008 and 2016, and also from the whole series including altogether seven separate data collections carried out every eight years from 1968 to 2016 and mainly covering Finns aged 15-69 years. Response rates show a falling trend (78% in 2000, 74% in 2008 and 60% in 2016). The overview also makes use of data collected within the European School Survey Project on Alcohol and other Drugs (ESPAD) and, for the elderly, the National FinSote study carried out by the Finnish Institute for Health and Welfare (THL). Results: After an all-time high of 12.7 litres of pure alcohol per capita 15 years and over in 2007, total consumption of alcohol had decreased by 21% by the year 2019. Underage drinking has decreased ever since the millennium shift. Older people's drinking has continued increasing or levelled out. Along with reduced total consumption, heavy episodic drinking (HED) has also decreased, but the differences between manual and white-collar workers in HED have continued to grow. Drinking alcoholic beverages with meals has also declined since 2008. Liberal and restrictive alcohol policy measures have alternated. Conclusions: Finnish drinking culture seems to change at a slow pace; several typical drinking habits have remained unchanged.

The contribution of drinking culture at comprehensive school to heavy episodic drinking from adolescence to midlife.

BACKGROUND: The school context is associated with adolescent alcohol use, but it is not clear whether this association continues into adulthood. This study examined whether exposure to drunkenness oriented drinking culture in 9th grade school class is associated with individuals' heavy episodic drinking (HED) from adolescence to midlife. METHODS: Participants in the 'Northern Swedish Cohort' study aged 16 years in 1981 were followed-up when aged 18, 21, 30 and 43 (N = 1080). Individual-level factors were HED, positive attitudes towards drunkenness, early initiation of HED and peer-oriented spare-time. School class-level drinking culture was measured as classmate reported HED, positive attitudes, early initiation of HED and peer-oriented spare time. Multilevel log-binomial regression analyses were adjusted for gender, parental socioeconomic background, family structure and HED at age 16. RESULTS: After adjustment for sociodemographic factors several cross-sectional and longitudinal associations were found between class-level indicators of drinking culture and individual HED. After additional adjustment for age 16 HED, most associations attenuated. The risk ratio (95% confidence interval) for engaging in HED at age 43 was 1.58 (1.03-2.42) times higher for those who at age 16 had many classmates reporting positive attitude towards drunkenness. CONCLUSIONS: These findings suggest that drinking culture in school may have a long-lasting impact on drinking habits in adulthood. The associations with HED at follow-ups are likely mediated by HED in adolescence. Studies on alcohol use would benefit from taking into account both individual and contextual factors in a life course perspective.

Public health effects of gambling - debate on a conceptual model.

BACKGROUND: Gambling for money is a popular leisure time activity in most countries, which has major social and economic impacts not only affecting the gambler, but his/her significant others, and the society. Gambling impact studies can help researchers and policymakers compare the health and social costs and benefits of different gambling policies and can be used when considering which gambling policies will reduce or increase costs or benefits the most. In a public health approach, the impacts of gambling, negative and positive, are assessed across the entire severity spectrum of the activity. Although some studies have created basic principles for conducting impact studies, a theoretical model is currently lacking. The aim of this debate is to review complementing and contrasting views on the effects of gambling to create a conceptual model, where a public health perspective is applied. MAIN TEXT: The effects of gambling can be structuralized using a conceptual model, where impacts are divided into negative and positive; costs and benefits. Costs and benefits are categorized into three classes: financial, labor and health, and well-being. These classes manifest in personal, interpersonal, and societal levels. Individual impacts cause effects on a personal level to gamblers themselves. External impacts influence the interpersonal and society/community levels and concern other people. The temporal level refers to the development, severity and scope of the gambling impact. These include general impacts, impacts of problem gambling and long-term impacts of gambling. CONCLUSIONS: The conceptual model offers a base on which to start building common methodology for assessing the impact of gambling on the society. While measuring monetary impacts is not always straightforward, the main issue is how to measure the social impacts, which are typically ignored in calculations, as are personal and interpersonal impacts. The reviewed empirical work largely concentrated on the costs of gambling, especially costs on the community level. The Model can be used to identify areas where research is scarce. Filling the gaps in knowledge is essential in forming a balanced evidence base on the impacts of gambling. Ideally, this evidence could be the starting point in formulating public policies on gambling.

Alcohol expenditure in grocery stores and their associations with tobacco and food expenditures.

BACKGROUND: Alcohol consumption is a significant cause of disease, death and social harm, and it clusters with smoking tobacco and an unhealthy diet. Using automatically registered retail data for research purposes is a novel approach, which is not subject to underreporting bias. Based on loyalty card data (LoCard) obtained by a major Finnish retailer holding a market share of 47%, we examined alcohol expenditure and their associations with food and tobacco expenditures. METHODS: The data consisted of 1,527,217 shopping events in 2016 among 13,274 loyalty card holders from southern Finland. A K-means cluster analysis was applied to group the shopping baskets according to their content of alcoholic beverages. The differences in the absolute and relative means of food and tobacco between the clusters were tested by linear mixed models with the loyalty card holder as the random factor. RESULTS: By far, the most common basket type contained no alcoholic beverages, followed by baskets containing a small number of beers or ciders. The expenditure on food increased along with the expenditure on alcoholic beverages. The foods most consistently associated with alcohol purchases were sausages, soft drinks and snacks. The expenditure on cigarettes relative to total basket price peaked in the mid-price alcohol baskets. CONCLUSION: Clustering of unhealthy choices occurred on the level of individual shopping events. People who bought many alcoholic beverages did not trim their food budget. Automatically registered purchase data provide valuable insight into the health behaviours of individuals and the population.

Longitudinal prospective associations between psychological symptoms and heavy episodic drinking from adolescence to midlife.

AIM: This study examined whether development of psychological symptoms (PS) differed between persons with different longitudinal profiles of heavy episodic drinking (HED) from adolescence to midlife. In addition, the reciprocal associations between PS and HED were studied. METHODS: Participants of a Finnish cohort study in 1983 at age 16 ( N = 2194) were followed up at ages 22 ( N = 1656), 32 ( N = 1471), and 42 ( N = 1334). HED was assessed with frequency of intoxication (16-22 years) and having six or more drinks in a session (32-42 years). Using latent class analysis, the participants were allocated to steady high, increased, moderate, and steady low groups according to their longitudinal profiles of HED. The PS scale (16-42 years) covered five mental complaints. The latent growth curve of PS was estimated in the HED groups for comparisons. In addition, the prospective associations between symptoms and HED were examined using cross-lagged autoregressive models. RESULTS: PS grew from 16 to 32 years, but declined after that, with women having higher level of PS than men. PS trajectory followed a path at highest and lowest level in the steady high and steady low HED groups, respectively. Symptoms predicted later HED, but the association in the opposite direction was not found. CONCLUSIONS: The more the HED trajectory indicated frequent HED, the higher was the level of PS throughout the follow-up. Results support the self-medication hypothesis, suggesting that alcohol is used to ease the burden of PS. More attention should be paid to alcohol use of people with mental symptoms in health services.

Social relationships in adolescence and heavy episodic drinking from youth to midlife in Finland and Sweden - examining the role of individual, contextual and temporal factors.

BACKGROUND: Applying the Process-Person-Context-Time (PPCT) model of the bioecological theory, this study considers whether proximal processes between the individual and the microsystem (social relationships within family, peer group and school) during adolescence are associated with heavy episodic drinking (HED), from youth to midlife, and whether the macro level context (country) plays a role in these associations. METHODS: Participants of two prospective cohort studies from Finland and Sweden, recruited in 1983/1981 at age 16 (n = 2194/1080), were followed-up until their forties using postal questionnaires. Logistic regression analysis was used to examine associations between social relationships at age 16 and HED (at least monthly intoxication or having six or more units of alcohol in one occasion) at ages 22/21, 32/30 and 42/43. Additive interactions between microsystem settings, as well as between settings and country, were also considered. RESULTS: Consistent with the PPCT model, we found individual, contextual and temporal aspects to be associated with drinking habits. Higher levels of poor family relationships were associated with an increased likelihood of HED (ages 22/21 and 32/30) in both Finnish women and men and Swedish men. Higher levels of peer contact were associated with an increased likelihood of HED in both Finnish women (ages 32 and 42) and men (ages 22 and 32), and Swedish men (age 21). In contrast with the other groups, poorer relationships with classmates were associated with an increased likelihood of HED (age 30) for Swedish women only. For women, the combined effect of having both daily peer contact and living in Finland for HED at age 42/43 was statistically distinguishable from a pure additive effect. CONCLUSIONS: Micro and to a lesser extent macro level contexts are associated with heavy episodic drinking well into adulthood. The most relevant processes in the adolescent microsystem occur in family and peer settings. However, long-lasting protective or risk-raising effects between different settings and later HED were not found. Promoting good relationships across different contexts during adolescence may reduce the incidence of HED in adulthood.

Socioeconomic differences in the use of alcohol and drunkenness in adolescents: Trends in the Health Behaviour in School-aged Children study in Finland 1990-2014.

AIMS: The aims of this study were to explore time-based trends of socioeconomic differences in alcohol use and drunkenness in Finnish adolescents from 1990 to 2014 and to investigate the significance of two indicators in detecting socioeconomic differences in alcohol use and drunkenness. METHODS: Data were retrieved from seven surveys conducted as part of the Health Behaviour in School-aged Children (HBSC) study in Finland from 1990 to 2014. The alcohol use and drunkenness of 15-year-old students, as well as socioeconomic status, including educational aspiration and perceived family wealth, were assessed via a self-report questionnaire. Logistic regression models were used to investigate the relationships between alcohol use, drunkenness and indicators of socioeconomic status. RESULTS: The study showed that the alcohol use and drunkenness of Finnish 15-year-old adolescents have decreased since the late 1990s. However, the level of decrease is not consistent among different socioeconomic groups and socioeconomic differences in drinking behaviour between two educational aspiration groups have persisted over two decades. Girls from the groups with low perceived family wealth were more likely to be frequently drunk in the time period 2006-2014. CONCLUSIONS: This study suggests that students with low educational aspiration should be the target population for interventions aiming at reducing the alcohol use and drunkenness of Finnish adolescents. In future interventions aimed at reducing heavier drinking, adolescents (especially girls) from less wealthy families should be the first priority. Further studies on trends in socioeconomic differences in alcohol use and drunkenness in adolescence should be conducted using different indicators of socioeconomic status and other social context factors should also be taken into account.
