AI Article Synopsis
- The study examined tobacco use among breastfeeding women in low- and middle-income countries (LMICs) using data from various health surveys conducted between 2010 and 2019.
- The overall prevalence of tobacco use in this group was found to be 3.61%, with significant regional variations; the highest prevalence was in Southeast Asia (6.13%) and the lowest in the Americas (1.44%).
- The research highlights that illiterate and economically disadvantaged women are disproportionately affected by tobacco use and emphasizes the need for targeted interventions to improve health outcomes for mothers and children in LMICs.
Article Abstract
Background: Smoking and smokeless tobacco use during the postpartum period is well studied in high-income countries, whereas low-income and middle-income countries (LMICs) lack evidence.
Methods: In this cross-sectional study we used data from the Demographic and Health Surveys (DHS) and Multiple Indicator Cluster Surveys (MICS) conducted in 78 LMICs between January 2010 and December 2019 to study tobacco use among 0.32 million sample lactating women. Age-standardized prevalence of smoking and smokeless tobacco use was estimated and presented with a 95% Confidence Interval (CI) for 78 LMICs. Pooled estimates overall and by WHO regions were obtained using random-effects meta-analyses. Country-level and community-level variance to understand contextual factors was also quantified using multilevel modelling.
Findings: Pooled prevalence of any tobacco use among breastfeeding women in LMICs was 3.61% (95% CI 3.53-3.70); with the lowest prevalence in regions of the Americas (1.44%, 1.26-1.63) and the highest in the Southeast Asia region (6.13%, 6.0-6.27). The pooled prevalence of tobacco smoking was reported to be 1.16% (1.11-1.21), with the highest prevalence in the Eastern Mediterranean region (4.27%, 3.88-4.67) and the lowest in the African region (0.81%, 0.76-0.86). The pooled prevalence of smokeless tobacco use was reported to be 2.56% (2.49-2.63), with the highest prevalence in the Southeast Asia region (4.92%, 4.80-5.04). Illiterate and poor women in LMICs bore the enormous burden of tobacco use.
Interpretation: The prevalence of smoking and smokeless tobacco use among lactating women in LMICs varied considerably across different WHO regions. Considering the cross-sectional design of the study, caution is required while interpreting the results. To improve mothers' and children's health and nutrition outcomes and reduce health inequalities in LMICs, reducing tobacco use through evidence-based interventions is critical.

Article Synopsis
- The study analyzes 36 years of tobacco use trends in northern Sweden using data from the MONICA project, involving over 12,000 participants.
- Cigarette smoking has significantly decreased, with rates dropping to 4.9% for men and 9.7% for women by 2022, while snus (a form of smokeless tobacco) use rose, particularly among men, stabilizing around 26.2%.
- Overall, while smoking rates have fallen, snus usage has become more prevalent across both genders, especially over the past few decades.
Importance: Cardiovascular health outcomes associated with noncigarette tobacco products (cigar, pipe, and smokeless tobacco) remain unclear, yet such data are required for evidence-based regulation.
Objective: To investigate the association of noncigarette tobacco products with cardiovascular health outcomes.
Design, Setting, And Participants: This cohort study was conducted within the Cross Cohort Collaboration Tobacco Working Group by harmonizing tobacco-related data and conducting a pooled analysis from 15 US-based prospective cohorts with data on the use of at least 1 noncigarette tobacco product ranging between 1948 and 2015.
