Pdf Summary

The study "Impacts of Household Tobacco Smoke on Life-long Non-smoking Adults: An Internet-based Population Survey in India" investigates the prevalence of long-term breathlessness limiting exertion among lifelong non-smokers exposed to second-hand smoke at home. The survey, conducted in February 2023 with English-speaking adults aged 18 and above, categorizes respondents based on their exposure to household tobacco smoke. Findings indicate that 46% of non-smokers living with a smoker experienced long-term breathlessness compared to 31% of non-smokers in non-smoking households.<br /><br />Data analysis through multivariable binary logistic regression, adjusted for age, sex, and rurality, revealed that exposure to household tobacco smoke doubles the risk of long-term breathlessness, with an adjusted odds ratio of 2.06. The study highlights a particular prevalence among younger, urban women. <br /><br />The research underscores a significant symptom burden among non-smokers due to household smoke exposure, suggesting that the findings may underestimate the true prevalence due to the study's limitations, including an English-only sample and a lack of quantification for the duration and intensity of second-hand smoke exposure. <br /><br />The results call for a proactive approach from clinicians to inquire about second-hand smoke exposure in patients and for educational efforts directed at smokers regarding the harm their habit causes to others. The study supports broader initiatives to reduce exposure to tobacco smoke, further reinforcing the public health impact of tobacco and the necessity for regulatory and educational interventions to safeguard non-smokers.
