ABSTRACT
Background:
Increasing cigarette
prices has been associated with improved perinatal and child health outcomes.
Transnational tobacco companies have adopted pricing strategies which maintain
the availability of cheap cigarettes. We aimed to assess associations between median cigarette prices, cigarette price
differentials and infant mortality in Europe.
Methods:
We conducted a longitudinal ecological study of 276 regions in 23
European countries from 2004 to 2014.
We obtained median cigarette prices and the differential between these and minimum
cigarette prices from Euromonitor International. We calculated pricing differentials
between minimum and median cigarette price as proportions of the median price. Prices were adjusted for inflation. Associations
of median prices and price differentials with annual infant mortality rates were
assessed using linear fixed-effect panel regression models adjusted for smoke-free
policies; Gross Domestic Product; unemployment rate; education; maternal age;
and underlining temporal trends. The analysis was conducted at a regional
level.
Results:
A €1 per pack increase in the median cigarette price was associated with
a decline of -0.23 infant deaths per 1,000 live births in the same year (95%
Confidence Interval [CI]: -0.37 to -0.09) and -0.16 per 1,000 live births the
following year (95% CI: -0.30 to -0.03). An increase of 10% in the price
differential between median and minimum priced cigarettes was associated with
an increase of 0.07 infant deaths per 1,000 live births (95% CI: 0.01 to 0.13)
the following year. Cigarette price increases across 23 European countries
between 2004 and 2014 were associated with 9,208 (95% CI: 8,601 to 9,814) fewer
infant deaths; an estimated 3,195 (95% CI: 3,017 to 3,372) infant deaths could have
been avoided had there been no differential between median and the minimum priced
cigarettes during this period.
Conclusions:
Combined
with other evidence this research suggests that legislators should implement
tobacco tax and price control measures which eliminate budget cigarettes.
