Study shows as cigarette taxes rise, infant death rate falls

Could cigarette taxes help lower newborn and infant death rates?

Yes, claims a new study. The researchers suggest that pregnant women are less likely to smoke when tobacco taxes are raised, leading to fewer infants being exposed to secondhand smoke.

Smoking during pregnancy and secondhand smoke exposure are known to increase the risk of infant death, the study authors noted.

Previous research has shown that boosting tobacco taxes is the most effective way to reduce tobacco use and associated health risks, especially among poorer people. A tobacco tax rate of 75% or more is recommended by the World Health Organization.

In the new study, the researchers examined the link between tobacco taxes and newborn/infant death rates by analyzing data from 2008 through 2018 in

159 countries. Overall, the average newborn death rate was

14.4 per 1,000 live births and the death rate among infants younger than a year old was 24.9 per 1,000, according to the report published online recently in PLOS Global Public Health.

However, the death rates were much higher in low/medium-income countries (33 infants under age 1, including 19 newborns, per 1,000) than in high-income countries (four newborns and six infants younger than age 1 per 1,000), the investigators found.

The average tax on cigarettes was just over 49%. Only 11% of low/middleincome countries and 42% of high-income countries had the WHO-recommended 75% tax rate.

A 10 percentage-point increase in total cigarette tax was associated with a

2.6% decrease in newborn deaths and a 1.9% decline in infant deaths, according to researcher Anthony Laverty, from Imperial College London, and his colleagues.

Based on those rates, an estimated 231,220 infant deaths, including 181,970 newborn deaths, might have been prevented in

2018 if all of the countries in the study had a cigarette tax rate of at least 75%, the researchers concluded in a journal news release.
