Article Abstract

Objective: To systematically review published articles reporting the use of smoking cessation mobile health (mHealth) interventions in Latin America.

Methods: Five different databases were searched from database inception to 2020. Criteria: (1) the research was a smoking cessation randomized controlled trial (RCT), quasi-experimental research, or single-arm study; (2) the intervention used at least one type of mHealth intervention; (3) the research was conducted in Latin American; and (4) the research reported the cessation rate.

Results: Of the seven selected studies, four were conducted in Brazil, two in Mexico, and one in Peru. Only one study was an adequately powered RCT. Interventions relied on text messages ( = 3), web-based tools ( = 2), and telephone calls ( = 3). Some studies ( = 4) provided pharmacotherapy support. Smoking cessation outcomes included self-reported ( = 5) and biochemically verified ( = 2) abstinence. Follow-ups were conducted at Month 6 ( = 2), Week 12 ( = 4), and Day 30 ( = 1). Cessation rates varied from 9.4% at Week 12 to 55.5% at Day 30.

Conclusion: Despite the promising cessation rates of mHealth interventions in Brazil, Mexico, and Peru, there is a need to rigorously evaluate these interventions in different Latin American countries with RCTs that are long-term, adequately powered, and use biochemical verification of cessation.

Introduction: In women, smoking during pregnancy and the postpartum period has important consequences for maternal and infant health, and interventions to assist smoking cessation during this period are essential. Although smoking has been associated with the presence of mental health problems, few studies addressing the factors associated with perinatal smoking have examined the role of stress. The aim of this review was to identify the relationships between the presence of stress and smoking during pregnancy and the postpartum period.

Smoking is highly prevalent and persistent among people with mental illness, but implementation of smoking cessation care by mental healthcare professionals (MHCPs) is lagging behind. This study took a broad approach to understanding implementation of stop smoking support (SSS) by MHCPs (N = 220 for main analyses), incorporating background characteristics, psychosocial factors, client factors, and organizational/environmental factors. Variable selection was based on previous work and the Consolidated Framework for Implementation Research.

Aim: In February 2024, the Aotearoa New Zealand Government repealed legislation to mandate very low nicotine cigarettes (VLNCs), greatly reduce the number of tobacco retailers and disallow sale of tobacco products to people born after 2008 (smokefree generation). We investigated acceptability and likely impacts of these measures among people who smoke or who recently (≤2 years) quit smoking.

Method: We analysed data from 1,230 participants from Wave 3 (conducted in late 2020 and early 2021) and 615 participants from Wave 3.
