Daily Smoking and Subjective Health Complaints in Adolescence

National prevalence of smoking among adolescents at tobacco tax increase and COVID-19 pandemic in South Korea, 2005-2022

Prior research has predominantly focused on the overall effects of the tobacco tax increase and the COVID-19 pandemic on adolescent smoking behavior. However, there is a need to examine both the immediate and sustained associations of these two factors on subgroups of adolescents, employing an interrupted time-series model. We aimed to investigate the immediate and sustained association of tobacco tax increase and the COVID-19 pandemic on adolescent smoking prevalence. This study utilized data from the Korea Youth Risk Behavior Web-Based Survey to analyze the prevalence of current smoking among all participants (CSP) and the prevalence of daily smoking among current smokers (DSP) of Korean adolescents (n = 1,159,995; mean, age 14.99; male 51.5%) over 18 years from 2005 to 2022. The study examined 18-year trends in CSP and DSP among Korean adolescents, emphasizing the influences of the 2015 tobacco tax increase and the COVID-19 pandemic, using β coefficients and their differences (βdiff) from an interrupted time-series ARIMA model. While CSP exhibited a decreasing trend, DSP exhibited an increasing trend. Tobacco tax increase was associated with both the short and long terms in smoking prevalence, however, the short-term association on prevalence (CSP, - 3.076 [95% CI, - 3.707 to - 2.445]; DSP, - 4.112 [95% CI, - 6.488 to - 1.735]) was stronger. The pandemic was associated with an immediate increase in DSP (9.345 [95% CI, 5.285-13.406]). These effects were strongest among adolescents from low economic status and those exposed to familial secondhand smoking. Supportive programs for adolescents in low-income families will help overcome the effects associated with the pandemic. As a tobacco tax increase was associated with a reduction in smoking prevalence, this could be one method to overcome the effects of the pandemic.

Physical Health Complaints in Adolescents

Abstract. Background: Some of the physical health complaints adolescents have, such as headaches and stomachaches, cannot be explained on a somatic level. It is unclear which psychological factors can explain these complaints: stress and social support are often discussed, but emotions rarely are. Aims: This cross-sectional study aims to use social support, stress, the tendency toward negative emotions, and health behaviors to predict physical health complaints in adolescents. Method: The 2018 HBSC (Health Behavior in School-aged Children) data from the German state of Brandenburg was analyzed via structural equation and path modeling ( N = 3,068, age M = 13.05). Results: Results showed that the tendency toward negative emotions seems to be a better predictor for health complaints (β = .35) than stress (β = .17), and even better suited than social support (β = −.08) or health behavior (β = −.06 to β = .16). In the analysis of specific emotions (anger, sadness, and fear), correlations were low and between sadness and complaints they were highest (average β = .19). Limitations: The present cross-sectional study could not examine long-term outcomes. In addition, the results are limited to only a few physical complaints. Future long-term studies should examine multiple disease symptoms in adolescence. Conclusion: The investigated tendency toward negative emotions demonstrated promising results to better understand the relationship between psychological factors and physical health complaints. As negative emotions were particularly important in predicting physical health, prevention programs for adolescents should focus on dealing with negative emotions to improve their health.

Mental Well-Being: 2010-2018 Trends among Italian Adolescents

(1) Aims: To explore temporal trends 2010-2018 of well-being among Italian adolescents and to evaluate potential explanatory factors. (2) Methods: Italian nationality representative samples of students aged 11, 13, and 15 years were recruited in 2010, 2014, and 2018; Health Behaviour in School-aged Children (HBSC), for an overall number of 165,000 teenagers. Multivariable logistic regression models were performed to fit the trends over time of life satisfaction (LS), psychological (PSY-HC) and somatic health complaints (SOM-HC) considering the contextual factors: school work pressure, social support (family, school, peers), socioeconomic status, geographic area, and immigration background; (3) Results: From 2010 to 2018 while LS was steady, health complaints increased, mainly for PSY-HC, in all age and gender groups. Trend of PSY-HC affected mainly 15-years-olds: rates among boys varied from 29.6% to 35.9% (OR: 1.13, 95%CI: 1.02-1.25); among girls from 49.1% to 63.3% (OR: 1.56, 95%CI: 1.42-1.72). High school work pressure and poor social support play a central role in worsening well-being outcomes; (4) Conclusions: Our findings pictured a remarkable worsening trend of teenagers' well-being, especially among 15-year-old girls. Further research will be required to investigate this breaking up of the connection between psychophysical symptomatology and cognitive perception of life satisfaction.

Trends in multiple health complaints in Polish adolescents in light of data from 30 European countries and Canada (2002-2018)

Background

Adolescence is a sensitive period accompanied by rapid developmental changes that can result in health complaints. The aim of the study was to describe the trend of subjective health complaints (HBSC-SCL) of Polish adolescents compared to their peers from 30 other countries and to rank all countries based on a proposed standardised measure.

Material and Methods

Data from the Health Behaviour in School-Aged Children (HBSC) study collected from 2002 to 2018 were used. The overall number of respondents from 30 countries in the combined sample from five quadrennial rounds was 773,356, including 49.2% boys and 50.8% girls. The HBSC-SCL is a non-clinical measure consisting of eight health complaints, usually analysed in two dimensions of psychological and somatic symptoms. Linear regression analysis was applied to assess the significance of trends of the total index and two subindices in the combined sample and individual countries.

Results

A significant increasing trend for the eight-item index appeared in Poland only in 13- and 15-year-olds, while only among 15-year-olds in the combined sample from 30 countries. Standardised country rank varied between -1.85 and 2.48 (worst). The countries that achieved extreme negative values (>=1) are France, Hungary, Italy, and Sweden, and the rank for Italy is considerably higher than for other countries. In Poland, the standardised rank for psychological symptoms exceeded the threshold of +1 in 2018.

Conclusions

The HBSC-SCL index could be useful for monitoring change in adolescent mental health. The proposed method of ranking may allow a broader view of the differences and similarities between countries and help to identify those performing unfavourably against cross-country patterns.

A bio-ecological framing of evidence on the determinants of adolescent mental health - A scoping review of the international Health Behaviour in School-Aged Children (HBSC) study 1983-2020

This paper extracts, organises and summarises findings on adolescent mental health from a major international population study of young people using a scoping review methodology and applying a bio-ecological framework. Population data has been collected from more than 1.5 million adolescents over 37 years by the Health Behaviour in School-Aged Children: WHO Cross-National (HBSC) Study. The paper reviews the contribution that this long standing study has made to our understanding of the individual, developmental, social, economic, cultural determinants of adolescent mental health by organising the findings of 104 empirical papers that met inclusion criteria, into individual, microsystem, mesosystem and macrosystem levels of the framework. Of these selected papers, 68 were based on national data and the other 36 were based on international data, from varying numbers of countries. Each paper was allocated to a system level in the bio-ecological framework according to the level of its primary focus. The majority (51 papers) investigate individual level determinants. A further 28 concentrate primarily on the microsystem level, 6 on the mesosystem level, and 29 on the macrosystem level. The paper identifies where there is evidence on the determinants of mental health, summarises what we have learned, and highlights research gaps. Implications for the future development of this population health study are discussed in terms of how it may continue to illuminate our understanding of adolescent mental health in a changing world and where new directions are required.

Healthy Lifestyle in Children and Adolescents and Its Association with Subjective Health Complaints: Findings from 37 Countries and Regions from the HBSC Study

Background: It is important to clearly understand the factors associated with subjective health complaints. The study aimed to investigate the relationship between subjective health complaints, several health behaviors, and a composite measure of healthy lifestyle. Methods: Data were from the Health Behaviour in School-aged Children (HBSC) 2014 international database. Participants were 167,021 children and adolescents, aged 10–16 years, from 37 countries and regions. A composite score of healthy lifestyle was created using a combination of daily physical activity, daily consumption of fruit and vegetables, <2 hours spent daily in screen-based behaviors, no drinking, and no smoking. The subjective health complaints assessed were headaches, stomach aches, backache, dizziness, feeling low, irritability, nervousness, and sleep difficulties. Results: Those who engage in physical activity every day, spend less than two hours a day in screen-based behaviors, do not drink alcohol, and do not smoke tobacco presented a higher likelihood of not having subjective health complaints. A healthy lifestyle was significantly related to having less of all the subjective health complaints. Those with a healthy lifestyle were 50% (OR = 0.5, 95% CI: 0.5–0.6, p < 0.001) less likely to have multiple health complaints. Conclusions: Healthy behaviors and healthy lifestyles are related with less subjective health complaints and less multiple health complaints.

Comparison of the health and well-being of smoking and non-smoking school-aged children in Ireland

BACKGROUND

Although most young people are aware of the long-term consequences of smoking, it has been shown that young smokers expect to give up before any health damage occurs. Little is known in an Irish context about the association between smoking and young people's current health. This could be helpful to help reduce smoking initiation and encouraging quitting. The study aimed to determine the association between smoking and health and well-being indicators among Irish school-aged children.

METHODS

The 2014 Irish Health Behaviour in School-aged Children study was analysed, which comprised a random stratified sample of 9,623 schoolchildren (aged 10-18). The prevalence of eight self-reported health complaints and two subjective well-being measures were compared across strata classified by self-reported smoking status using Pearson's chi square and independent t tests. Logistic regression and ordinal regression were used to control for age, gender, and social class.

RESULTS

A significantly larger proportion of smokers (p < .001) reported fair to poor health (32% versus 11% for non-smokers), lower mean life satisfaction scores (6.2 compared with 7.5), and each of eight health complaints at least once a week (range = 25-50% compared with 15-21%). These patterns remained significant after adjusting for differences in age, gender, and social class profile (p < .001).

CONCLUSIONS

The study demonstrates the potential of developing initiatives, which target smoking in adolescence as opposed to the longer term health effects of smoking which are well known. The findings can be utilized to counteract positive perceptions of smoking among schoolchildren. This, combined with providing supports to help children quit, may help achieve government targets to reduce smoking prevalence.

[Trends in educational inequalities in smoking among adolescents in Germany : Evidence from four population-based studies]

BACKGROUND

In Germany, smoking prevalence among adolescents has significantly declined since the early 2000s. However, data show that adolescent smoking rates considerably differ between different types of secondary schools. The aim of our study was to examine how educational inequalities in adolescent smoking behaviour have developed over time.

METHODS

Data were used from four population-based studies (each consisting of repeated cross-sectional surveys from 2001-2015): the representative surveys of the Federal Centre for Health Education, the German Health Interview and Examination Survey for Children and Adolescents, the Health Behaviour in School-aged Children Study, and the European School Survey Project on Alcohol and Other Drugs. Each study comprised different age groups (within the age range of 11-17 years) and used different smoking measures. Adolescents' educational status was based on the attended type of secondary school. Absolute and relative educational inequalities were presented as prevalence differences and prevalence ratios, respectively.

RESULTS

Despite methodical differences, all four studies similarly reveal that adolescent smoking rates have significantly declined in all educational groups. However, lower smoking rates among secondary school students attending higher educational tracks could be observed. While absolute educational inequalities tended to decrease over time, relative inequalities between educational groups remained rather stable or even increased.

DISCUSSION

Declining adolescent smoking rates suggest that smoking may have lost some of its attractiveness for young people. Our findings further emphasize the importance of tobacco control measures such as raising cigarette taxes, smoking bans, and increasing minimum legal age for tobacco purchase. As relative educational inequalities in adolescent smoking rates did not diminish over time, setting- and target group-specific interventions should focus more on students in middle and lower secondary school tracks.

Health complaints among adolescents in Norway: A twenty-year perspective on trends

Purpose

Examine time trends in health complaints among adolescents in Norway between 1994 and 2014 and among population subgroups, e.g., age and gender, as well as their interactions.

Methods

Norwegian data on 11-16-year-olds were drawn from the Health Behaviour in School-aged Children survey (HBSC) and analyzed for 1994 (n = 4,952), 1998 (n = 5,026), 2002 (n = 5,023), 2006 (n = 4,711), 2010 (n = 4,342) and 2014 (n = 3,422). Design adjusted linear regression that accounts for clustering effects was used to examine mean scores of two subscales of the HBSC-symptom checklist: psychological and somatic health complaints.

Results

Psychological and somatic health complaints among adolescents in Norway followed somewhat different trajectories, but the mean scores of both types of health complaints appeared to increase during the 20-year period. For psychological health complaints, there was a three-way interaction between age, gender and time, indicating that increasing trends in health complaints depended on both age and gender, in which older adolescent girls had a greater increase over time relative to younger adolescents and boys.

Conclusions

Findings from this study, together with earlier findings, suggest that there has been an increasing trend in health complaints among adolescents in Norway from 1994 to 2014, especially among older adolescent girls. Future research should examine if trends in health complaints also depend on gender and age in other contexts. This will help the planning and implementation of tailored and effective interventions.

Temporal trends in adolescents' self-reported psychosomatic health complaints from 1980-2016: A systematic review and meta-analysis

OBJECTIVE

There is increasing concern that mental health may be deteriorating in recent generations of adolescents. It is unclear whether this is the case for self-reported psychosomatic health complaints (PSHC).

METHOD

We conducted a systematic review and meta-analysis of published primary studies on PSHC in the general adolescent population over time. The primary databases were MEDLINE, Embase and PsycINFO, which were searched from inception to November 2016. Studies were included if they involved an observational design, presented self-reported data from participants aged 10-19 years and included data from at least two time points, five years apart. Inclusion and study quality were assessed by two independent reviewers.

RESULTS

Twenty-one studies were included; 18 reported trends on the prevalence of PSHC in a single country, while three studies reported on multiple countries. In total, over seven million adolescents from 36 countries in Europe, North America, Israel and New Zealand were represented, covering the period 1982-2013. In the descriptive analysis, 10 studies indicated a trend of increasing PSHC, eight showed a stable trend and three showed a decreasing trend at certain points in time. The results from the meta-analysis showed a mean odds ratio (OR) of 1.04 (K = 139, 95% CI 1.01-1.08) for PSHC from 1982 to 2013, thus indicating a minor increase in general. In the subgroup analysis, this minor increase was observed mainly between the 1980s and 2000s, while the trend appeared to be more stable between the 2000s and 2010s. Some differences were also found between multinational subregions. Findings from subgroup analysis, however, only supported a significant increasing trend in Northern Europe.

CONCLUSION

There may have been a minor increasing trend in adolescent self-rated PSHC between the 1980 and 2000s, but has become more stable since the 2010s, from a multinational perspective. Northern Europe was the only region to show a clearly significant minor increasing trend, without being the region with the highest total prevalence of PSHC at the present time. The discrepant trends regarding PSHC between regions and the reliance on self-reported data may reflect true changes in the occurrence of PSHC in the adolescent population. However, they may also reflect changes in how adolescents perceive and report health complaints.
