A recent study published in The Lancet highlights the extensive impact of second-hand smoke, with over 2.7 billion people, including 767 million children, exposed globally in 2023.

This exposure contributed to approximately 1.66 million premature deaths and significant health issues, particularly ischemic heart disease and respiratory infections in children.

Despite a decline in smoking prevalence since 1990, the number of people exposed remains stable due to population growth.

The study urges governments to enforce stricter tobacco controls to protect non-smokers, especially women and children, from second-hand smoke's harmful effects.

PARIS, Sept 8 — More than 2.7 billion people including children have been exposed to second-hand smoke globally, contributing to nearly 1.7 million deaths in 2023, according to study published Tuesday in The Lancet.

Tobacco remains a leading cause of disease globally, the study said, noting many “non-smokers exposed to second-hand smoke” were among the estimate total of 8 million people who died in 2023 of smoking-related illnesses.

“Exposure to second-hand smoke is a globally recognised health risk, with no safe level of inhalation,” it said.

By reviewing studies published in the US National Institutes of Health database PubMed along with population surveys, Tuesday’s study sought to estimate the prevalence of exposure to second-hand smoke and quantify the burden of disease in 204 countries and territories between 1990 and 2023.

Among the approximately 2.7 billion people exposed to second-hand smoke in 2023 were 767 million children aged 0 to 14, the study found.

This exposure is estimated to have resulted in 1.66 million premature deaths and causing premature disability and illness, leading with ischaemic heart disease, a heart condition caused by insufficient oxygen supply to the heart muscle.

In children, exposure to second-hand smoke is estimated to have caused 5.2 million respiratory tract infections in 2023, it said.

People in proximity to someone lighting up are exposed to both the “sidestream smoke” from the burning tobacco product and smoke exhaled by the active smoker, the study explained.

“The sidestream component, which dominates the air non-smokers breathe, is unfiltered... carrying higher per-unit concentrations of the toxic and carcinogenic compounds” than that being inhaled by the active smoker, it said.

Despite significant declines in smoking prevalence globally since 1990, the absolute number of people exposed has remained stable due to population growth and increased exposure in Africa and the Middle East.

Women are also disproportionately affected by second-hand smoke, particularly in regions where smoking prevalence among women is low, it noted.

“Despite this substantial burden, (second-hand smoke) exposure remains rarely acknowledged as a major risk factor for female health,” it said.

The study called for governments to implement stronger tobacco controls in public places and in homes in order to better protect women and children from second-hand smoke. — AFP

《柳叶刀》上发表的一项最新研究强调了二手烟的广泛影响，到 2023 年，全球将有超过 27 亿人（包括 7.67 亿儿童）暴露于二手烟中。

这种暴露导致约 166 万人过早死亡，并引发了严重的健康问题，特别是儿童缺血性心脏病和呼吸道感染。

尽管自 1990 年以来吸烟率有所下降，但由于人口增长，接触烟草的人数仍然保持稳定。

该研究敦促各国政府实施更严格的烟草管制措施，以保护非吸烟者，特别是妇女和儿童，免受二手烟的有害影响。

巴黎，9 月 8 日——根据周二发表在《柳叶刀》上的一项研究，全球有超过 27 亿人（包括儿童）暴露于二手烟中，导致 2023 年近 170 万人死亡。

该研究指出，烟草仍然是全球疾病的主要原因，并指出许多“接触二手烟的非吸烟者”是预计在 2023 年死于吸烟相关疾病的 800 万人中的一部分。

“接触二手烟是全球公认的健康风险，没有任何安全的吸入量，”声明中写道。

周二发布的这项研究通过回顾美国国立卫生研究院数据库 PubMed 中发表的研究以及人口调查，试图估算 1990 年至 2023 年间 204 个国家和地区接触二手烟的流行情况，并量化其疾病负担。
