Trends in the psychosocial characteristics of 11-15-year-olds who still drink, smoke, take drugs and engage in poly-substance use in England

Trends in psychosomatic symptoms among adolescents and the role of lifestyle factors

BACKGROUND

Adolescent mental health problems are on the rise globally, including in Sweden. One indicator of this trend is increased psychosomatic symptoms (PSS) over time. Lifestyle factors such as physical activity (PA), diet, smoking, and alcohol consumption may influence the time trends in PSS; however, the evidence base is scarce. The aim of this study was to investigate associations between time trends in PSS and lifestyle factors.

METHODS

The study was based on data collected from a nationally representative sample of 9,196 fifteen-year-old boys and girls in Sweden using the Health Behavior in School-aged Children (HBSC) symptom checklist. The sample comprised nearly equal proportions of girls (50.5%) and boys. The lifestyle factors examined in this study included PA, regular breakfast intake, consumption of fruits, vegetables, sweets, or soft drinks, smoking, and alcohol drunkenness. We used data from 2002 to 2018 and stratified by family affluence scale (FAS) to demonstrate how the associations varied among the FAS groups. We fitted separate regression models for the high- and low-FAS groups, where interaction terms between the year of survey and each lifestyle factor were used to estimate the level and direction of associations between the factors and trends in PSS.

RESULTS

There was a generally increasing trend in PSS mean scores from 2.26 in 2002 to 2.49 in 2018 (p <.001). The changes in each survey year compared to the average mean scores during the preceding years were significant in all years except 2010. Regular breakfast intake, daily fruit and vegetable consumption, and higher PA were associated with lower PSS mean scores, while smoking and drunkenness had opposite associations with PSS. The only significant interaction between survey year and the lifestyle factors was observed regarding drunkenness in the high FAS group, suggesting that the association between trends in PSS and the experience of getting drunk at least twice got stronger over time (B = 0.057; CI:0.016, 0.097; p <.01).

CONCLUSIONS

The results indicate increasing trends in PSS among young people in Sweden from 2002 to 2018, with a significant increase observed among adolescents in the high FAS group who reported getting drunk on at least two occasions.

Have the personality and socio-demographic profiles of Australian adolescent drinkers changed?

INTRODUCTION

Adolescent alcohol consumption has been declining across many countries, with rates of abstinence also increasing among younger cohorts. A range of socio-demographic variables and personality traits are associated with alcohol use; however, no study has examined whether the relationship between personality and drinking has changed over time as adolescent drinking has declined.

METHODS

Data from 15- to 17-year-old respondents were extracted from four waves (2004/2005, 2008/2009, 2012/2013, 2016/2017) of a long running Australian cohort study. Logistic regression analyses with interaction terms were used to determine whether personality traits (openness, conscientiousness, extraversion, agreeableness and emotional stability) and socio-demographic variables (age, gender, equivalised income, family structure, cultural background, school attendance and regionality) significantly differed between drinkers and abstainers and whether these relationships changed across cohorts.

RESULTS

The prevalence of drinking for 15- to 17-year-olds significantly declined over each survey wave from 54% in 2004/2005 to 24% in 2016/2017. Conscientiousness (odds ratio [OR] 0.82, confidence interval [CI] = 0.73, 0.93), extraversion ([OR] 1.25, [CI] = 1.11, 1.40) and emotional stability ([OR] 0.73, [CI] = 0.64, 0.83) were all significant predictors of alcohol consumption. No significant interactions between cohort and personality traits or socio-demographic variables were found.

DISCUSSION AND CONCLUSIONS

The study found no evidence to indicate that the relationship between adolescent alcohol consumption and personality has changed. Similarly, socio-demographic relationships with drinking were stable as drinking prevalence dropped by more than half. This adds to the evidence that drinking declines among adolescents are spread broadly across the population and not concentrated within identifiable sub-groups of young people.

Examining the association between psychological distress and alcohol use in Australian adolescents over a period of declining consumption

INTRODUCTION

Youth drinking rates have declined over the past 15 years while self-reported psychological distress has increased, despite a well-recognised positive relationship between the two. The current study aimed to identify changes in the relationship between psychological distress and alcohol use in adolescents from 2007 to 2019.

METHODS

This study used survey responses from 6543 Australians aged 14-19 years who completed the National Drug Strategy Household Survey in 2007, 2010, 2013, 2016 or 2019. Logistic and multivariable linear regressions with interactions (psychological distress × survey wave) predicted any alcohol consumption, short-term risk and average quantity of standard drinks consumed per day.

RESULTS

Psychological distress was a positive predictor of alcohol use and this association remained stable across survey waves as alcohol consumption decreased.

DISCUSSION AND CONCLUSIONS

The relationship between distress and alcohol consumption remained relatively steady, even as youth drinking declined and distress increased. The proportion of drinkers experiencing distress did not increase as consumption rates dropped, suggesting that the decline in youth drinking is occurring independently of the increase in self-reported and diagnosed mental health issues.

Psychosocial correlates of drinking transitions: A longitudinal study among adolescents in Sweden

INTRODUCTION

Non-drinkers have been shown in older studies to have poorer mental health and social life compared to their alcohol-using counterparts. Given the profound decline in adolescent drinking observed in most high-income countries, this pattern may have changed. This study explores drinking transitions and examines psychosocial factors among adolescents by longitudinal drinking status.

METHODS

Data were based on two waves of a prospective longitudinal nationwide study (n = 4018). The first wave (T1) of data was collected in 2017 (age 15/16) and the second wave (T2) was in 2019 (age 17/18). Respondents were asked about their past year drinking status, general health, psychosomatic problems, psychiatric medication, school enjoyment, emotional symptoms, peer relationship problems, prosocial ability, friendships satisfaction and satisfaction with relation to mother/father. Comparisons by mean values were assessed and multinomial logistic regressions were used to examine associations.

RESULTS

Abstainers and later drinkers differed significantly from early drinkers on 9/10 factors respectively at T1. Fewer psychosomatic problems, less psychiatric medication, higher school enjoyment, more emotional symptoms, higher parental relationship satisfaction, more peer problems and lower friendships satisfaction at T1 were associated with abstaining and/or later drinking. All factors were more strongly associated with abstaining. School enjoyment predicted abstaining but not later drinking.

DISCUSSION AND CONCLUSIONS

Longitudinal drinking status relates to small to moderate systematic psychosocial differences. Adolescents with better mental health, more content relationships with parents and lower friendships satisfaction are more often abstainers. Those generally worse off are more likely early drinkers but they also have better friendships.

Longitudinal patterns of polysubstance use throughout adolescence: association with adult substance use and psychosocial outcomes controlling for preadolescent risk factors in a male cohort

PURPOSE

Inconsistent reports raise the question of the extent to which poor adult outcomes are associated with adolescent polysubstance use (PSU: alcohol, marijuana, other illicit drugs) above and beyond earlier risk factors.

METHODS

Early adulthood substance-related and psychosocial outcomes were examined in association with age 13 to 17 developmental patterns of PSU in boys from urban, low SES neighborhoods (N = 926). Three classes obtained by latent growth modeling described low/non-users (N = 565, 61.0%), lower risk PSU (later onset, occasional use, 2 ≤ substances; N = 223, 24.1%), and higher risk PSU (earlier onset, frequent use, 3 ≥ substances; N = 138, 14.9%). Preadolescent individual, familial and social predictors of adolescent PSU patterns were used as covariates.

RESULTS

Adolescent PSU contributed to both age-24 substance-related outcomes (frequency of alcohol, drug use, and getting drunk, risky behaviors under influence, and use-related problems) and psychosocial outcomes (no high school diploma, professional or financial strain, ASP symptoms, criminal record) over and above preadolescent risk factors. Controlling for preadolescent risk factors, adolescent PSU made a more important contribution to adult substance use outcomes (increasing the risk by about 110%) than to psychosocial outcomes (16.8% risk increase). PSU classes showed poorer adjustment for all age-24 substance use, and for various psychosocial outcomes than low/non-users. Higher risk polysubstance users also reported poorer outcomes than their lower risk peers for most substance use outcomes, and for professional or financial strain and criminal record.

CONCLUSION

Findings highlight the contribution of adolescent PSU in a dose-response fashion, over and above preadolescent risk factors, on both homotypic and heterotypic outcomes in early adulthood.

Youth drinking in decline: What are the implications for public health, public policy and public debate?

Youth drinking has declined across most high-income countries in the last 20 years. Although researchers and commentators have explored the nature and drivers of decline, they have paid less attention to its implications. This matters because of the potential impact on contemporary and future public health, as well as on alcohol policy-making. This commentary therefore considers how youth drinking trends may develop in future, what this would mean for public health, and what it might mean for alcohol policy and debate. We argue that the decline in youth drinking is well-established and unlikely to reverse, despite smaller declines and stabilising trends in recent years. Young people also appear to be carrying their lighter drinking into adulthood in at least some countries. This suggests we should expect large short- and long-term public health benefits. The latter may however be obscured in population-level data by increased harm arising from earlier, heavier drinking generations moving through the highest risk points in the life course. The likely impact of the decline in youth drinking on public and policy debate is less clear. We explore the possibilities using two model scenarios, the reinforcement and withdrawal models. In the reinforcement model, a 'virtuous' circle of falling alcohol consumption, increasing public support for alcohol control policies and apparent policy successes facilitates progressive strengthening of policy, akin to that seen in the tobacco experience. In the withdrawal model, policy-makers turn their attention to other problems, public health advocates struggle to justify proposed interventions and existing policies erode over time as industry actors reassert and strengthen their partnerships with government around alcohol policy. We argue that disconnects between the tobacco experience and the reinforcement model make the withdrawal model a more plausible scenario. We conclude by suggesting some tentative ways forward for public health actors working in this space.

Are changes in attitudes towards school associated with declining youth drinking? A multi-level analysis of 37 countries

BACKGROUND

Changes in adolescents' attitudes towards school are a potential explanation for recent declines in young people's alcohol consumption. However, this has not been tested using multi-national survey data, which would permit stronger causal inferences by ruling out other country-specific explanations. This study, therefore, uses an international survey of schoolchildren to examine the associations between changing attitudes towards school and adolescent alcohol consumption.

METHODS

We used data from 247 325 15-year-olds across 37 countries participating in four waves of the Health Behaviour in School-aged Children study (2001/02-2013/14). Attitudes towards school were assessed using two measures-self-reported pressure from schoolwork and whether respondents like school. Outcome measures were weekly alcohol consumption and having been drunk twice in one's lifetime. We used whole population and gender-specific hierarchical linear probability models to assess the relationship between attitudes and alcohol outcomes within countries over time.

RESULTS

Country-level changes over time in liking school were not associated with changes in alcohol consumption. However, a 10% increase in feeling pressured by schoolwork was associated with a 1.8% decline in drunkenness [95% confidence interval (CI): -3.2% to -0.3%] and weakly associated with a 1.7% decline in weekly drinking (95% CI: -3.6% to 0.2%). Among girls only, increases in feeling pressured by schoolwork were associated with a 2.1% decline in weekly drinking (95% CI: -3.7% to -0.6%) and a 2.4% decline in drunkenness (95% CI: -3.8% to -1.1%).

CONCLUSION

Changes in attitudes towards school may have played a minor role in the decline in alcohol consumption among adolescent girls only.
