Mindfulness programs for problematic usage of the internet: A systematic review and meta-analysis.
Behavioral AddictionProblematic usage of the internet (PUI) is an umbrella term for a range of uncontrolled, excessive, and potentially harmful online behaviors. Recently, numerous studies have examined the potential of mindfulness programs (MPs) for reducing PUI. We conducted a comprehensive systematic review and meta-analysis in this emerging field.
We searched eight databases from inception to October 18, 2022, with no language restrictions. We included randomized controlled trials (RCTs) and nonrandomized trials (NRTs). The primary outcome was change in self-reported PUI, the secondary outcome was change in screen time.
Of 3,473 identified records, 19 RCTs and 20 NRTs with a total of 1,549 participants were included. Participation in an MPwas associated with large reductions in PUI in between-group analysis in RCTs (k = 19; g = -1.67; 95% CI -2.15, -1.19) and in within-group pre-post analysis in all studies (k = 35; g = -1.67; 95% CI -1.99, -1.36). Screen time showed a medium reduction in within-group pre-post analysis (k = 10; g = -0.65; 95% CI -0.90, -0.41). The effects for PUI remained significant in a series of sensitivity analyses, such as excluding low quality studies, excluding outliers, adjusting for publication bias, or using follow-up data. Heterogeneity between studies was high and the overall quality of evidence was rated low.
MPs are probably effective in reducing PUI and might be effective in reducing screen time. Shortcomings in the quality of evidence highlight the need for high-quality controlled trials with long-term follow-ups to confirm results.
Evolving methodology of national tobacco control investment cases.
Tobacco ControlThis article describes an investment case methodology for tobacco control that was applied in 36 countries between 2017 and 2022.
The WHO Framework Convention on Tobacco Control (FCTC) investment cases compared two scenarios: a base case that calculated the tobacco-attributable mortality, morbidity and economic costs with status quo tobacco control, and an intervention scenario that described changes in those same outcomes from fully implementing and enforcing a variety of proven, evidence-based tobacco control policies and interventions. Health consequences included the tobacco-attributable share of mortality and morbidity from 38 diseases. The healthcare expenditures and the socioeconomic costs from the prevalence of those conditions were combined to calculate the total losses due to tobacco. The monetised benefits of improvements in health resulting from tobacco control implementation were compared with costs of expanding tobacco control to assess returns on investment in each country. An institutional and context analysis assessed the political and economic dimensions of tobacco control in each context.
We applied a rigorous yet flexible methodology in 36 countries over 5 years. The replicable model and framework may be used to inform development of tobacco control cases in countries worldwide.
Investment cases constitute a tool that development partners and advocates have demanded in even greater numbers. The economic argument for tobacco control provided by this set of country-contextualised analyses can be a strong tool for policy change.
Interpreting results, impacts and implications from WHO FCTC tobacco control investment cases in 21 low-income and middle-income countries.
Tobacco ControlTobacco control investment cases analyse the health and socioeconomic costs of tobacco use and the benefits that can be achieved from implementing measures outlined in the WHO Framework Convention on Tobacco Control (WHO FCTC). They are intended to provide policy-makers and other stakeholders with country-level evidence that is relevant, useful and responsive to national priorities and policy context.
This paper synthesises findings from investment cases conducted in Armenia, Cabo Verde, Cambodia, Chad, Colombia, Costa Rica, El Salvador, Eswatini, Georgia, Ghana, Jordan, Laos, Madagascar, Myanmar, Nepal, Samoa, Sierra Leone, Sri Lanka, Suriname, Tunisia and Zambia. We examine annual socioeconomic costs associated with tobacco use, focusing on smoking-related healthcare expenditures, the value of lives lost due to tobacco-related mortality and workplace productivity losses due to smoking. We explore potential benefits associated with WHO FCTC tobacco demand-reduction measures.
Tobacco use results in average annual socioeconomic losses of US$95 million, US$610 million and US$1.6 billion among the low-income (n=3), lower-middle-income (n=12) and upper-middle-income countries (n=6) included in this analysis, respectively. These losses are equal to 1.1%, 1.8% and 2.9% of average annual national gross domestic product, respectively. Implementation and enforcement of WHO FCTC tobacco demand-reduction measures would lead to reduced tobacco use, fewer tobacco-related deaths and reduced socioeconomic losses.
WHO FCTC tobacco control measures would provide a positive return on investment in every country analysed.
Equity implications of tobacco taxation: results from WHO FCTC investment cases.
Tobacco ControlAcross time, geographies and country income levels, smoking prevalence is highest among people with lower incomes. Smoking causes further impoverishment of those on the lower end of the income spectrum through expenditure on tobacco and greater risk of ill health.
This paper summarises the results of investment case equity analyses for 19 countries, presenting the effects of increased taxation on smoking prevalence, health and expenditures. We disaggregate the number of people who smoke, smoking-attributable mortality and cigarette expenditures using smoking prevalence data by income quintile. A uniform 30% increase in price was applied across countries. We estimated the effects of the price increase on smoking prevalence, mortality and cigarette expenditures.
In all but one country (Bhutan), a one-time 30% increase in price would reduce smoking prevalence by the largest percent among the poorest 20% of the population. All income groups in all countries would spend more on cigarettes with a 30% increase in price. However, the poorest 20% would pay an average of 12% of the additional money spent.
Our results confirm that health benefits from increases in price through taxation are pro-poor. Even in countries where smoking prevalence is higher among wealthier groups, increasing prices can still be pro-poor due to variable responsiveness to higher prices. The costs associated with higher smoking prevalence among the poor, together with often limited access to healthcare services and displaced spending on basic needs, result in health inequality and perpetuate the cycle of poverty.
Advancing progress on tobacco control in low-income and middle-income countries through economic analysis.
Tobacco ControlMore than 80% of the world's 1.3 billion tobacco users live in low-income and middle-income countries (LMICs), where progress to address tobacco and its harms has been slow. The perception that tobacco control detracts from economic priorities has impeded progress. The Secretariat of the WHO Framework Convention on Tobacco Control (FCTC) is leading the FCTC 2030 project, which includes technical assistance to LMICs to analyse the economic costs of tobacco use and the benefits of tobacco control.
The Secretariat of the WHO FCTC, United Nations Development Programme and WHO supported 21 LMICs between 2017 and 2022 to complete national investment cases to guide country implementation of the WHO FCTC, with analytical support provided by RTI International. These country-level cases combine customised estimates of tobacco's economic impact with qualitative analysis of socio-political factors influencing tobacco control. This paper overviews the approach, observed tobacco control advancements and learnings from 21 countries: Armenia, Cabo Verde, Cambodia, Chad, Colombia, Costa Rica, El Salvador, Eswatini, Georgia, Ghana, Jordan, Laos, Madagascar, Myanmar, Nepal, Samoa, Sierra Leone, Sri Lanka, Suriname, Tunisia and Zambia.
Tobacco control advancements in line with investment case findings and recommendations have been observed in 17 of the 21 countries, and many have improved collaboration and policy coherence between health and economic stakeholders.
Tobacco control must be seen as more than a health concern. Tobacco control leads to economic benefits and contributes to sustainable development. National investment cases can support country ownership and leadership to advance tobacco control.
Biomarkers of metal exposure in adolescent e-cigarette users: correlations with vaping frequency and flavouring.
Tobacco ControlYouth vaping poses a significant public health concern as metals have been detected in e-cigarette aerosols and liquids. This study investigated factors associated with biomarkers of metal exposure.
Data were drawn from Wave 5 of the Population Assessment of Tobacco and Health (PATH) Study Youth Panel, a nationally representative sample of US adolescents aged 13-17 years. Urinary biomarkers of exposure to cadmium, lead, and uranium were assessed by vaping frequency (occasional (1-5 days), intermittent (6-19 days), and frequent (20+ days)) in the past 30 days and flavour type (menthol/mint, fruit, and sweet).
Among 200 exclusive e-cigarette users (median age 15.9 years, 62.9% female), 65 reported occasional use, 45 reported intermittent use, and 81 reported frequent use. The average number of recent puffs per day increased exponentially by vaping frequency (occasional: 0.9 puffs, intermittent: 7.9 puffs, frequent: 27.0 puffs; p=0.001). Both intermittent (0.21 ng/mg creatinine) and frequent users (0.20 ng/mg creatinine) had higher urine lead levels than occasional users (0.16 ng/mg creatinine). Frequent users also had higher urine uranium levels compared with occasional users (0.009 vs 0.005 ng/mg creatinine, p=0.0004). Overall, 33.0% of users preferred using menthol/mint flavours, 49.8% fruit flavours, and 15.3% sweet flavours. Sweet flavour users had higher uranium levels compared with menthol/mint users (0.009 vs 0.005 ng/mg creatinine, p=0.02).
Vaping in early life could increase the risk of exposure to metals, potentially harming brain and organ development. Regulations on vaping should safeguard the youth population against addiction and exposure to metals.

Compliance and alternative behaviors of heavy gamers in adolescents to Chinese online gaming restriction policy.
Behavioral AddictionIn 2021, China implemented a policy to prevent adolescents from excessive online gaming, with the goal of encouraging healthier leisure activities.
Three months after this policy was implemented, we conducted a study involving 430 Chinese adolescents who regularly played online games for over two hours daily before the policy. We collected their responses to the restriction, including their compliance with the policy, engagement in undesirable alternative behaviors (e.g., watching short videos), and engagement in desirable alternative behaviors (e.g., playing sports). We also collected data on individual factors, parental technology interference, and feelings of restriction to use as predictors for behaviors, including those related to violating the restriction or watching short videos.
A small percentage of heavy gamers violated the restriction by renting others' game accounts (3%) or using a family member's identity (14%), while 59% of the sample shifted to watching short videos. Heavy gamers who lived in rural areas, spent more time on online games prior to the policy, did not feel restricted from playing online games, and experienced parental technology interference were more likely to violate the restriction. Females or those lacking stable hobbies were more inclined to watch short videos.
Although the policy restricted heavy gaming, it has also led to increased short video use. Policymakers could explore alternative approaches, such as developing infrastructure that supports outdoor leisure activities in rural areas, encouraging parents to model responsible technology use behaviors, and guiding adolescents to cultivate positive hobbies in their leisure time.
Implementation costs of the appraise alcohol brief intervention (ABI) for male remand prisoners: A micro-costing protocol and preliminary findings.
AddictionThis paper documents the methods used to assess the implementation costs of the APPRAISE alcohol brief intervention (ABI) delivered to male remand prisoners across two study sites in Scotland and North East England.
We first developed a comprehensive taxonomy of the activities constituting the APPRIASE ABI. Next, data were collected for each activity about the study staff and the subject time spent, in addition to the other resources used and unit costs.
From the pilot data collection it was possible to construct a narrative, for both study sites, for how the intervention was delivered and the time required for each activity. The ABI was delivered by Change Grow Live and Humankind intervention staff and staff salaries were obtained from both organizations to calculate the staff delivery costs for each site. Other costs, such as the printing of materials, were estimated based on APPRAISE study records. Due to the ongoing Covid-19 restrictions and limited access to prison resources and staff, there were significant deviations from the initial study protocols. As a result, we document the costs of implementing the ABI as delivered rather than as planned.
This paper provides the first estimates of the implementation costs of an ABI delivered in criminal justice setting in the UK. Although these costs are from a pilot implementation that was heavily impacted by the Covid-19 pandemic, this paper nonetheless provides useful, policy-relevant information on the potential costs of providing ABI to remand prisoners. It also serves as a methodological template, guidance, and proof of concept for future micro-costing studies of ABIs in criminal justice settings.
Problematic smartphone use and academic achievement: A systematic review and meta-analysis.
Behavioral AddictionThe present study aimed to synthesize existing quantitative evidence on the relationship between problematic smartphone use (PSU) and academic achievement with a focus on quantifying its magnitude and examining its potential moderators.
Eligible studies were searched for up to February 10, 2023 in six different databases (i.e., MEDLINE, Current Contents Connect, PsycINFO, Web of Science, SciELO, and Dissertations & Theses Global). Studies were considered eligible if they provided information derived from self-report instruments that allowed statistical calculation of the relationship between PSU and academic achievement. Pooled effect sizes (r) were computed using a random-effects model. Meta-regressions were conducted to test the influence of study-level moderators on the relationship of interest. Influence analyses and a three-parameter selection model (3PSM) were conducted to examine the robustness of the results and publication bias, respectively.
A total of 33 effect sizes from 29 studies (n = 48,490) were retrieved. Results showed a small effect size (r = -0.110), which tended to be larger in samples consisting of students from elementary and middle schools.
Findings from the present study contribute to the understanding of a potential determinant of decreased academic achievement by providing evidence that PSU may be one of them.
