Tobacco use and sleep loss over worry among adolescents aged 12-15 years: A population-based study of 38 countries.

ABSTRACT:

Background

Sleep loss is increasingly recognized as a key public health issue among adolescents. Tobacco use is one of the leading causes of preventable disease and death in the world. Yet, the association between tobacco use and sleep loss has been understudied in the adolescent population. This study aimed to examine this association utilizing nationally representative samples of adolescents.

Methods

Cross-sectional data on 109?408 adolescents (12-15 years) from 38 countries were derived from the Global School-based Student Health Survey (GSHS). Weighted age- and sex-adjusted distribution of each sample characteristics was calculated. Multivariate logistic regression and meta-analyses were performed to assess the association of sleep loss over worry with any tobacco use, while controlling for important confounders, including age, gender, loneliness, physical attack victimization, parental knowledge/warmth, and perceived peer kindness/helpfulness.

Results

The weighted age- and sex-adjusted prevalence of SLOW and use of any tobacco product was 6.4% and 7.4% respectively across 38 countries. The overall odds of sleep loss over worry were 1.89 times (95% confidence interval (CI)?=?1.75, 2.03) greater among tobacco users than among non-users, with low level of between-country heterogeneity (I² ?=?24.0%, P?=?0.095). The odds of sleep loss over worry were 1.61 times (95% CI?=?1.52, 1.71) greater among those reporting physical attack victimization than among non-victims, and 5.55 times (95% CI?=?4.95, 6.21) greater among those reporting frequent than less frequent loneliness.

Conclusions

Tobacco use, physical attack victimization, and loneliness can be key indicators of SLOW, and may be included in the assessment and prevention of SLOW to generate a more comprehensive picture. Further studies are needed to determine if reducing tobacco use, loneliness, or physical attack victimization would make a meaningful impact on reducing SLOW.

Project description:IntroductionSecondhand smoking (SHS) may be a risk factor for obesity in adolescence, but data on the association between SHS and obesity are scarce, especially from low- and middle-income countries (LMICs). Therefore, the aim of this study was to assess the association between SHS and obesity among adolescents aged 12-15 years from 38 LMICs.MethodsCross-sectional data from 38 LMICs that participated in the Global School-based Student Health Survey (GSHS) were analyzed. Body mass index was calculated based on measured weight and height. The 2007 WHO Child Growth reference was used to define obesity. SHS was categorized as no exposure, non-daily exposure (ie, 1-6 days), and daily exposure (ie, 7 days) based on the number of days exposed to secondhand smoke in the past 7 days. Multivariable logistic regression and meta-analyses were conducted to assess the associations.ResultsThe analyzed sample consisted of 88 209 adolescents aged 12-15 years who never smoked. The overall prevalence of non-daily and daily SHS was 34.2% and 15.7%, respectively. After adjustment for potential confounders, compared with no SHS, there was no significant association between non-daily SHS and obesity (odds ratio [OR] = 0.94; 95% confidence interval [CI] = 0.86-1.02), but adolescents who reported daily SHS were significantly more likely to have obesity (OR = 1.19; 95% CI = 1.06-1.34).ConclusionsThe prevalence of SHS was high among adolescents in LMICs, and daily SHS was associated with a significant increase in odds of obesity. Future studies with longitudinal designs are warranted to assess causality and whether prevention of SHS can reduce the risk of obesity in adolescence.ImplicationsIn the present large multi-country study on adolescents aged 12-15 years from LMICs, nearly half of the students were exposed to non-daily or daily secondhand smoke. Overall, while non-daily SHS was not significantly associated with obesity, adolescents who reported daily SHS had a significant 1.19 (95% CI = 1.06-1.34) times higher odds of obesity than those who reported no exposure to secondhand smoke. To the best of our knowledge, this is the first multi-country study on SHS and obesity from LMICs, and also the largest study on this topic to date.

Project description:BackgroundSmokeless tobacco use is popular in some regions worldwide, but it receives less attention compared to cigarette smoking. We aimed to estimate the recent prevalence of, and trends in, smokeless tobacco use and to examine its associated factors among adolescents aged 12-16 years in 138 countries/territories (hereafter "countries") from 1999 to 2019.MethodsData from the Global Youth Tobacco Survey conducted in 138 countries in 2010-2019 and the National Youth Tobacco Survey conducted in the United States in 2019 were used to calculate the prevalence of current smokeless tobacco use and investigate its associated factors among adolescents aged 12-16 years. We also assessed the trend in the prevalence of smokeless tobacco use in 100 countries that had conducted more than one survey from 1999 to 2019.ResultsThe overall prevalence of current smokeless tobacco use was 4.4% (95% confidence interval [CI] 4.0-4.9), with 5.7% (5.1-6.3) for boys, 3.1% (2.6-3.5) for girls, 3.9% (3.5-4.4) for adolescents aged 12-14 years and 5.4% (4.8-5.9) for those aged 15-16 years. The prevalence was highest in the South-East Asian region (6.1%, 4.4-7.7) and lowest in the Western Pacific region (2.0%, 1.7-2.4). The prevalence of smokeless tobacco use decreased in 57 of 100 countries, increased in 32 countries, and remained unchanged in 11 countries. Current cigarette smoking (odds ratio [OR]=2.00, 95% CI=1.68-2.39), other tobacco product use (OR=6.03, 95% CI=4.92-7.40), tobacco advertisement exposure (OR=1.44, 95% CI=1.19-1.74), being offered free tobacco products (OR=2.01, 95% CI=1.66-2.42), and not being taught about dangers of smoking (OR=1.28, 95% CI=1.09-1.50) were all positively associated with current smokeless tobacco use.ConclusionsSmokeless tobacco use among adolescents remains a public health concern worldwide. Although the prevalence among adolescents decreased in most countries, it remains high especially in the South-East Asian region. More strict and effective strategies and measures are needed to further curb the smokeless tobacco use among adolescents.
