  • Alcohol Habits in Sweden during 1997-2009 with Particular Focus on 2005 and 2009, Assessed with the AUDIT : A Repeated Cross-Sectional Study
  • 2011
  • Ingår i: European Addiction Research. - : S. Karger AG. - 1022-6877 .- 1421-9891. ; 17:2, s. 90-96
  • Tidskriftsartikel (refereegranskat)abstract
    • Aim: This study aimed to survey the changes in alcohol habits during a period with the European Union legal practices. Methods: Alcohol habits in Sweden were surveyed in the general Swedish population at four timepoints, in 1997, 2001, 2005 and 2009, using the 10-item AUDIT questionnaire. Design: Four separate randomly drawn cross-sectional samples of 1,250 individuals were surveyed at each timepoint. Results: An average of 70% of the sampled individuals responded to the AUDIT questionnaire. Men had higher total AUDIT scores than women in 2005 and 2009, but scores increased among women 61-71 years old and decreased among men 61-71 years old. Younger men and women 17-27 years old decreased their AUDIT-C consumption scores by almost 20% between 2005 and 2009. An analysis of problem drinkers (+8 for men/+6 for women) indicated that a larger proportion of elderly women drank moderately in 2009 compared with 2005, but fewer elderly women drank hazardously. Conclusions: Earlier increases in drinking levels between 1997 and 2001 may reflect a latent high demand that was restricted by low availability. When availability due to European Union harmonization increased, alcohol consumption followed suit. After a period of adaptation, alcohol consumption appears to have stabilized.

  • Design of a Web-based individual coping and alcohol-intervention program (web-ICAIP) for children of parents with alcohol problems: study protocol for a randomized controlled trial
  • 2012
  • Ingår i: BMC Public Health. - : Springer Science and Business Media LLC. - 1471-2458. ; 12
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: It has been estimated that approximately 20% of all Swedish children grow up with parents having alcohol problems, which may result in negative outcomes among these children. Therefore, most Swedish municipalities provide resources for support, but at the same time figures reveal that not even 2% receive support, mainly due to difficulties in identifying and recruiting these children into support programs. Delivering intervention programs to children and adolescents via the Internet seems a promising strategy, but to date, the number of web-based interventions aimed at this target group is very scarce. We have therefore developed a novel internet-delivered therapist assisted self-management intervention called the web-ICAIP (Individual Coping and Alcohol Intervention Program) for adolescents having parents with alcohol problems. The purpose of the program is to strengthen adolescents' coping behavior, improve their mental health, and postponing the onset or decreasing risky alcohol consumption. This paper describes the web-ICAIP and the design of a randomized controlled trial (RCT) to measure the efficacy of this intervention. Methods/Design: The RCT will include at least 183 adolescents (15-19 year old) who will be randomly allocated to two conditions where one group has access to the web-ICAIP and the other is a waiting list control group. Participants will be recruited from websites containing information and facts for adolescents about alcohol and other drugs. Possible participants will be screened using the short version of the Children of Alcoholics Screening Test (CAST-6). The assessment consists of a baseline and two follow-up measurements taking place after two and six months, respectively. The primary outcomes include the Center for Epidemiological Studies Depression Scale (CES-DC), a coping behavior scale, and also the short version of the Alcohol Use Disorders Identification Test (AUDIT-C). Additional outcomes include the "Ladder of life" which measures overall life satisfaction and questions concerning program adherence. Discussion: There is an urgent need for developing and evaluating web-based intervention programs which target children having parents with alcohol problems. This study will therefore make an important contribution to this novel field of research.

  • 'Are The Times A-Changin'? Trends in adolescent substance use in Europe
  • 2018
  • Ingår i: Addiction. - : Wiley. - 0965-2140 .- 1360-0443. ; 113:7, s. 1317-1332
  • Tidskriftsartikel (refereegranskat)abstract
    • Aims To estimate temporal trends in adolescents' current cigarette, alcohol and cannabis use in Europe by gender and region, test for regional differences and evaluate regional convergence. Design and Setting Five waves of the European School Survey Project on Alcohol and Other Drugs (ESPAD) from 28 countries between 1999 and 2015. Countries were grouped into five regions [northern (NE), southern (SE), western (WE), eastern Europe (EE) and the Balkans (BK)]. Participants A total of 223 814 male and 211 712 female 15-16-year-old students. Measurements Daily cigarette use, weekly alcohol use, monthly heavy episodic drinking (HED) and monthly cannabis use. Linear and quadratic trends were tested using multi-level mixed-effects logistic regression; regional differences were tested using pairwise Wald tests; mean absolute differences (MD) of predicted prevalence were used for evaluating conversion. Findings Daily cigarette use among boys in EE showed a declining curvilinear trend, whereas in all other regions a declining linear trend was found. With the exception of BK, trends of weekly drinking decreased curvilinear in both genders in all regions. Among girls, trends in WE, EE and BK differed from trends in NE and SE. Monthly HED showed increasing curvilinear trends in all regions except in NE (both genders), WE and EE (boys each). In both genders, the trend in EE differed from the trend in SE. Trends of cannabis use increased in both genders in SE and BK; differences were found between the curvilinear trends in EE and BK. MD by substance and gender were generally somewhat stable over time. Conclusions Despite regional differences in prevalence of substance use among European adolescents from 1999 to 2015, trends showed remarkable similarities, with strong decreasing trends in cigarette use and moderate decreasing trends in alcohol use. Trends of cannabis use only increased in southern Europe and the Balkans. Trends across all substance use indicators suggest no regional convergence.

  • Anabolic Androgenic Steroids-Use and Correlates among Gym Users-An Assessment Study Using Questionnaires and Observations at Gyms in the Stockholm Region
  • 2011
  • Ingår i: International Journal of Environmental Research and Public Health. - Basel Switzerland : MDPI AG. - 1661-7827 .- 1660-4601. ; 8:7, s. 2656-2674
  • Tidskriftsartikel (refereegranskat)abstract
    • he purpose of this study was to estimate the prevalence of anabolic androgenic steroid (AAS) use and offers to use among gym users in Stockholm County (Sweden), and to conduct a comparison of concordance in estimates of AAS and supplements at gyms between two data collection methods. A questionnaire was distributed to members at 36 training facilities and 1,752 gym users participated in the study. An observation study was conducted as covert participant observations at 64 gyms. According to the questionnaire, 3.9% of men reported life time use of AAS, 1.4% use during the past 12 months and 0.4% AAS use during past 30 days. Not only were there similar patterns found in the two methods, i.e., similar age and gender distributions for AAS use, but analyses of concordance showed that gyms with a higher prevalence of self-reported AAS-use and supplement use (questionnaire) showed a significantly higher proportion of observer-assessed AAS users. Analyses of individual predictors showed that AAS users were almost always young men, regular weight trainers and more often users of drugs and nutritional supplements. The higher prevalence of AAS use among gym users than in the general population makes the former an appropriate target group for AAS prevention. The connection between supplements, drugs and AAS use suggests that effective AAS prevention need to focus on several risk factors for AAS use. The clear resemblance in estimates between the observation and questionnaire data strengthen the credibility of the two methods.

  • The increased trend of non-drinking in adolescence : The role of parental monitoring and attitudes toward offspring drinking
  • 2018
  • Ingår i: Drug and Alcohol Review. - : WILEY. - 0959-5236 .- 1465-3362. ; 37, s. S34-S41
  • Tidskriftsartikel (refereegranskat)abstract
    • Introductions and AimsThe proportion of adolescents who do not drink alcohol has increased during the last decade in many European countries, the USA and Australia. Few studies have addressed why this positive trend has occurred. The aim of the present study is to examine associations between parenting factors, peers' alcohol use and non-drinking among 15- to 16-year-old adolescents over time, from 2003 to 2015, and to evaluate potential gender differences. Design and MethodsData from the Swedish subsample of European School Survey Project on Alcohol and Other Drugs were used. Data were available for 2003, 2007, 2011 and 2015 in nation-based samples with responses from 11531 adolescents in total. ResultsThe proportion of non-drinkers increased from 23.2% in 2003 to 48.7% in 2015. For each year, indicators of especially restrictive attitudes toward offspring drinking were robustly associated with an increased probability of non-drinking. However, neither indicators of parental monitoring nor parental attitudes toward offspring drinking were associated with the increase in the proportion of non-drinkers that occurred from 2003 to 2015. Two indicators of parental monitoring were more strongly associated with non-drinking among girls than among boys, while paternal restrictive attitudes toward offspring drinking were more strongly associated with non-drinking among boys than girls. Discussion and ConclusionsParenting characteristics are important for adolescents who do not use alcohol, which has implications for prevention strategies. However, the increased trend of non-drinkers could not be attributed to parental factors.
