ObjectiveIn Indonesia, the second most natural disaster-prone country in the world, the tobacco industry exploits such crises via corporate social responsibility. The objective of this study was to map existing evidence on natural disasters and tobacco use in order to understand how tobacco control policies could be optimised in disaster-prone regions.DesignScoping review.Data sourcesScienceDirect, PubMed and Google Scholar, with searches conducted twice: between January and April 2024 and again in August 2025.Study selectionAll studies examining natural disasters, smoking behaviours and the tobacco industry.Data extractionStudies were assessed primarily on reports of tobacco use change, tobacco control policy enforcement, tobacco industry interference and mention of the role of stress. Data on country, disaster type, type of research study and sample details were also collated.Results27 of the 611 identified studies were included in the final analysis. Two-thirds of studies reported an increase in smoking rates following disasters. No studies mentioned tobacco control policy enforcement or tobacco industry interference during disasters. Most of the studies (74%) which examined the relationship between disaster-related stress and smoking found a positive association. About half (51.9%) of the studies described disasters in the Americas.ConclusionsSmoking rates often rise after stress-inducing disasters. More evidence is urgently required to assist countries like Indonesia in enforcing tobacco control and preventing tobacco industry interference.

Background Youth behavior is significantly influenced by their social environment and social media (SM). Susceptibility to e-cigarette use, defined as the likelihood of initiating e-cigarette use among non-users, is a critical early marker for prevention efforts. This study explores the interplay of social environment, SM marketing exposure, and individual traits in e-cigarette use and susceptibility among Indonesian youth, addressing a gap in non-Western contexts. Methods A school-based online survey of 1,600 Indonesian youth aged 15–24, conducted from March to August 2023 in Jakarta, Yogyakarta and East Kalimantan, assessed e-cigarette use, susceptibility, and predictors, including social environment, SM marketing exposure, and sensation-seeking behavior. Structural equation modeling and multinomial regression were used to analyze associations. Results Approximately 13.3% of students reported using e-cigarettes in the past 30 days, and 6.7–10.1% of non-users were susceptible to experimenting with e-cigarettes. Boys were significantly more likely than girls to be current (OR = 6.67, 95% CI [3.05–14.57]) and ever e-cigarette users (OR = 2.92, 95% CI [2.10–4.06]). Sensation-seeking (OR = 2.19, 95% CI [1.83–2.62]), e-cigarette use by horizontal family member (OR = 1.39, 95% CI [1.10–1.53]), number of friends using e-cigarettes (OR = 1.20, 95% CI [1.17–1.23]), and exposure to e-cigarette advertisements on Instagram and TikTok (OR = 1.35, 95% CI [1.20–1.53]) were significant predictors of current use. Among non-users, boys reported higher susceptibility to e-cigarette use than girls (β = 0.20, p  <.01). Sensation seeking (β = 0.24, p  <.01) and the number of friends using e-cigarettes (β = 0.22, p  <.01) were directly associated with susceptibility. Sex-specific patterns were observed: maternal and sisters’ e-cigarette use were associated with increased susceptibility among girls ( r  =.11, p  =.002; r  =.17, p  <.001), while grandfathers’ use was linked to higher susceptibility among boys ( r  =.21, p  <.001). Notably, TikTok exposure was uniquely associated with greater susceptibility among girls ( r  =.08, p  =.023). Conclusions SM, peers, and family significantly shape youth e-cigarette-related behavior. These findings underscore the need for targeted interventions, including banning e-cigarette advertising on SM, promoting peer-driven prevention strategies, and leveraging SM for educational campaigns to reduce youth e-cigarette use.

Background: In many countries, smoking rates are higher among men than women, highlighting the importance of focusing on factors that influence smoking prevalence among men. Expressed masculinities occur within settings that can influence men's perspectives and behaviours towards smoking. Objectives: To provide an overview of key aspects of how masculinities underpin men's behaviours regarding tobacco smoking. Methods: The Health, Illness, Men and Masculinities framework was used to develop a synthesis of masculinities captured in published articles about men's smoking behaviours. Five databases (PubMed, Medline Ovid, Embase, CINAHL and PsychINFO Ovid) and Google Scholar (up to April 2016) were searched using keywords derived from three concepts: men, smoking and health. In total, 351 articles that focused on smoking and used/implied masculinity concepts were identified. These underwent a two-stage screening process applying inclusion/exclusion criteria, first titles/abstracts and then full-text. Data from 45 selected articles were extracted and charted. Results: Regions with high prevalence of smoking among men, such as South East Asia and the Western Pacific, had a disproportionate number of studies on masculinity and smoking, with less exploration of masculinity as a protective factor, especially for young people, and men-specific settings to support non-smoking behaviour. Conclusions: Incorporating masculinity in future settings-based approaches to smoking-related health promotion programmes has the potential to reduce smoking prevalence among men.

Background Smoking is a leading cause of preventable death, disproportionately affecting people with low socioeconomic status (SES) and serious psychological distress (SPD). The U.S. Food and Drug Administration (FDA) has proposed reducing nicotine levels in cigarettes and other combusted tobacco products to minimally addictive levels, a policy with significant public health potential. However, misperceptions about very low nicotine cigarettes (VLNCs), such as beliefs that they are less harmful or ineffective for quitting, may reduce policy effectiveness. While previous randomized controlled trials (RCTs) have examined the effects of using VLNCs, none have incorporated messaging to address misperceptions. This study evaluates the impact of a messaging campaign on smoking behaviors, risk perceptions, and quit intentions among people who smoke, focusing on individuals with low SES, SPD, and neither. The primary objective is to assess whether exposure to VLNC-related messages reduces the number of cigarettes smoked per day compared to VLNC use alone. Secondary objectives include examining effects on other tobacco product use, nicotine dependence, forgoing cigarettes, perceived risks, and quit intentions. Methods This multi-site, open-label, parallel-arm RCT will enroll 1230 adults who smoke ( n  = 410 per group: with SPD, low SES, neither category). After a 1-week baseline period, participants will be randomized (1:1) to receive either (1) VLNCs with messaging or (2) VLNCs only (control). Messaging will include pack inserts and digital ads shown during weekly visits to address misperceptions and encourage quitting. Participants will complete daily logs via text messages and attend weekly visits over 4 weeks for data collection, including self-reported smoking behavior, expired carbon monoxide (CO) samples, and questionnaire assessments. The primary outcome is the number of cigarettes smoked per day in the final study week (week 4). Secondary outcomes include the use of other tobacco products, nicotine dependence, forgoing cigarettes, and quit intentions. Discussion This trial will be the first to examine the effects of a messaging campaign accompanying VLNC use among priority populations. Results will inform FDA regulatory strategies and public health messaging to support nicotine reduction policy implementation. Trial registration ClinicalTrials.gov NCT06787937.

The global obesity pandemic among adolescents is becoming a public health issue throughout the world. Telehealth use has significantly increased during and after the COVID-19 pandemic, including its application in adolescent obesity prevention and treatment. This review aims to synthesize the evidence on the effectiveness of telenutrition in improving dietary behavior and physical activity in adolescents with obesity. The PRISMA-P (Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols) guideline will be used to structure this protocol. The focus of the systematic review is guided by the population, intervention, comparator, and outcome (PICO) framework. A systematic search of Science Direct, PubMed, Cochrane, Embase, JMIR, ProQuest, and Google scholar databases will be conducted. Two authors will screen the titles and abstracts of identified studies independently and select studies according to the eligibility criteria. The full-text reading will be done independently by 2 reviewers to assess final eligibility. Any discrepancies will then be discussed and resolved. The Cochrane Collaboration Risk of Bias tool was used to assess the risk of bias; a descriptive analysis will summarize the effectiveness of the telenutrition or any type of telehealth intervention used. The systematic review is expected to be completed by the end of March 2024. The ongoing screening and review of the articles are currently being conducted. This systematic review aims to summarize the effectiveness, features, design process, usability, and coherence of a telenutrition intervention using behavior change theory to improve dietary patterns and physical activity among adolescents with obesity. It will identify areas for improvement and best practices, informing the development of more useful and engaging telenutrition interventions for adolescents.

Background: Despite the sustained high prevalence of smoking among Indonesian adult men, little is known about possible protective factors in this group. This study examined the relationship between key characteristics of masculinity (e.g., fatherhood status, being the main breadwinner or sole provider for the family) and current smoking behaviours (smoking status and cigarettes smoked per day (CPD)) among Indonesian men aged 18–49 years. Methods: In total, 2540 Indonesian men aged 18–49 participated in the United Nations Multi-Country Study on Men and Violence, 2012. Fatherhood status was categorised into three groups: nonfathers, new fathers and more experienced fathers. The association between fatherhood status and current smoking, as well as fatherhood status and cigarettes smoked per day (CPD), was estimated by employing logistic and zero-inflated negative binomial regressions, respectively. Results: Socioeconomic factors were associated with smoking behaviour among Indonesian adult men. The odds of smoking among new fathers and more experienced fathers were 2.3 (95% CI: 1.09–4.79) and 1.5 times (95% CI: 1.08–2.17) higher compared with nonfathers, respectively. Men who had a shared income with their partner or received income from their parents smoked 13% (95% CI 0.79–0.95) and 11% fewer CPD (95% CI 0.79–0.99) compared with men who were the main breadwinner, respectively. Conclusions: In this study, fatherhood represents an aspect of traditionally masculine roles, offering a new perspective for looking at smoking problems in Indonesia. Other key aspects of traditional masculinity characteristics, the breadwinner role, occupation and sources of family income had significant associations with smoking status and CPD. Men smoked fewer CPD as fathers and when sharing the financial responsibility for their family equally with their spouse.
