Extended hours of video game play and negative physical symptoms and pain
Video games are a source of positive experiences and joy for many people. However, some interaction styles may lead to negative consequences. We aimed to examine the potential negative physical problems associated with video gaming behaviors. Data were from the 2022 International Gaming Study (IGS22), a cross-sectional survey of 955 individuals aged 18–94 (M = 46.10 [16.19]; 45% male) who played video games. We examined the association between pr…
The Use and Knowledge Around Vaping and Their Correlates Among University Students—A Cross-sectional Australian Study
The increasing prevalence of e-cigarette use (“vaping”) among youth has emerged as a public health concern. We aim to explore vape use, knowledge levels, and correlates in a sample of Australian young adults. Participants from six residential university colleges in Queensland, Australia, were invited to complete an online survey. The sample included 716 students ( M age =18.1 years). Correlates of vape use and knowledge examined included socio-de…
The impact of tobacco tax increases on cost-minimising behaviours and subsequent smoking cessation in Australia
P - CMBs are associated with reduced smoking cessation. Reducing opportunities for industry to promote purchasing-related CMB options, such as by standardising pack sizes and reducing the price differential between RYO and manufactured cigarettes could increase the effectiveness of tax increases
Regional and Country Prevalence Estimates of Unsafe Sex Among Adolescents in 68 Low-Income and Middle-Income Countries
Prioritizing adolescent health is a public health priority to achieve the sustainable development goals, including reducing the risk of unsafe sex. Data on unsafe sex have remained scarce among adolescents in low-and middle-income countries (LMICs). To estimate the prevalence of unsafe sex in LMICs, we conducted secondary data analysis on the Global School-based Student Health Surveys among 244,863 students aged 13–17 years from 68 countries acro…

Beyond the Primary Influences of Parents and Peers on Very Young Adolescent Alcohol Use
This study examined the extent to which young adolescent alcohol use was related to alcohol-related norms and law enforcement of underage alcohol use, after accounting for known strong parent and peer correlates.

Two-level (individuals nested within communities) binary logistic regression was used to examine relationships between recent alcohol use (last …

Rural and Urban Differences in Adolescent Alcohol Use, Alcohol Supply, and Parental Drinking
PURPOSE: Alcohol use is more prevalent in rural than urban areas in adult populations. Few studies have focused on adolescent drinking. This study investigated if adolescents in regional and rural areas of Australia were more likely to drink alcohol and if there were differences in parental drinking and alcohol supply across regions. METHODS: A subsample from the National Drug Strategy Household Survey 2013, the largest nationally representative …
Trend in alcohol use in Australia over 13 years
These findings are partially consistent with and support Skog's collectivity theory. There has been a turnaround in alcohol consumption after a decade-long uptrend, as evident in the collective decreases in alcohol consumption among nearly all types of drinkers. There was also a turnaround in rate of treatment seeking, which peaked at 2007 and then decreased steadily. The timing of this turnaround differs with level of drinking, with non-high ris…

Differences in Receipt of Alcohol‐Related Care Across Rurality Among VA Patients Living With HIV With Unhealthy Alcohol Use
PURPOSE: It is unknown whether receipt of evidence-based alcohol-related care varies by rurality among people living with HIV (PLWH) with unhealthy alcohol use-a population for whom such care is particularly important. METHODS: All positive screens for unhealthy alcohol use (AUDIT-C ≥ 5) among PLWH were identified using Veterans Health Administration electronic health record data (10/1/09-5/30/13). Three domains of alcohol-related care were asses…

How many more young Australians say that they would use cannabis if it were legal
International differences in patterns of cannabis use among adult cigarette smokers
Patterns of tobacco and cannabis co-use differed between countries. Smokers in Canada and the US had higher rates of co-use, daily cannabis use, dual-daily use of both cannabis and cigarettes, and were more likely to perceive smoked cannabis as less harmful than cigarettes compared to England and Australia. Further attention as to how varying cannabis regulations may impact co-use patterns is warranted

Vaping on TikTok
Our findings illustrated that positively framed e-cigarette and vaping-related postings available without age restrictions on TikTok-a rising video-sharing platform that is popular among adolescents-have been viewed many times.

The Relationship between Cannabis and Tobacco Co-administration and Long-Term Patterns of Cannabis Use in Young Adults Who Use Stimulants
Background Co-administering cannabis with tobacco (i.e. co-administration of the substances mixed together) is a common practice among cannabis users, but the consequences of this practice are not well understood. This study examines the relationship between co-administering cannabis with tobacco and the long-term frequency of cannabis use in a young adult population group with high rates of cannabis and tobacco use.Methods The data are from an A…

State-Level Prevalence and Associates of Opioid Dependence in the USA
Traditionally, opioid-related disease burden was primarily due to heroin use. However, increases in extra-medical (or non-medicinal use of prescription opioids; NMPOs) use has precipitated the current overdose epidemic in North America. We aim to examine the state-level prevalence of heroin and NMPO dependence and their associations with opioid-related mortality and state-level socio-demographic profiles. Data were pooled from the 2005-2014 Natio…

Data from the 2018 (n = 27,169) and 2019 (n = 47,747) waves of the International Cannabis Policy Study …
Changes in Viewer Engagement and Accessibility of Popular Vaping Videos on TikTok
Whilst the depiction type and thematic distribution of removed videos suggest that TikTok may be removing a small proportion of content that promotes the use of e-cigarettes, metadata of remaining videos indicate an increase in viewer engagement. TikTok's removal of explicit substance-related hashtags from the platform could be a step towards preventing adolescents from being exposed to harmful behaviours and substances online. However, the platf…
Changes in patterns of youth multiple tobacco and/or e-cigarette product use in the US between 2014 and 2020
There was an increase in regular e-cigarette use in all three classes, but a corresponding decrease in the proportion of MTEP use. Public health interventions to discourage uptake of e-cigarettes, such as tighter restrictions on marketing to minors, are warranted and there is a need to consider disparities in the determinants of MTEP use
