8 Million Lives Saved Since Since Anti-Smoking Warning

A Yale study estimates that 8 million lives have been saved in the United States as a result of anti-smoking measures that began 50 years ago in January of 1964 with the groundbreaking report from the Surgeon General outlining the deadly consequences of tobacco use. The Yale School of Public Health-led analysis is published in the Journal of the American Medical Association.

A release from the university reports that the study used mathematical models to calculate the long-term effect of the seminal report, and subsequent anti-smoking measures, over the past half-century. These cumulative efforts have significantly reshaped public attitudes and behaviors concerning cigarettes and other forms of tobacco, note the researchers.

First author Theodore R. Holford, professor of biostatistics and member of Yale Cancer Center, and six other researchers who are part of the National Cancer Institute’s Cancer Intervention and Surveillance Modeling Network, found that while some 17.6 million Americans have died since 1964 due to smoking-related causes, 8 million lives have been saved as a result of increasingly stringent tobacco-control measures that beganwith the report’s January 11th, 1964, release.

Of the lives saved, approximately 5.3 million were men and 2.7 million were women. The total number of saved lives translates into an estimated 157 million years of life, a mean of 19.6 years for each beneficiary, report the researchers.

The release quotes Holford as saying, “An estimated 31% of premature deaths were avoided by this effort, but even more encouraging is the steady progress that was achieved over the past half-century, beginning with a modest 11% in the first decade to 48% of the estimate what we would have seen from 2004 to 2012 in the absence of tobacco control. Today, a 40-year-old man can expect on average to live 7.8 years longer than he would have in 1964, and 30% of that improvement can be attributed to tobacco control. The gains for women have been slightly less, 5.4 years, but tobacco control accounts for 29% of that benefit.”

Using data collected by the National Center for Health Statistics from 1965 to 2009, the team recreated smoking life history summaries for groups born each year starting in 1890. These were used along with national mortality statistics and studies that followed large populations to calculate mortality rates by smoking status. This allowed them to estimate the impact of alternative scenarios for what might have occurred had the era of tobacco control never happened.

The tobacco warning was released by then-U.S. Surgeon General Luther Terry. It is seen by many as a pivotal moment in American public health and as the opening salvo in an ongoing effort to convince people to stop smoking.
