BERNABE-ORTIZ, Antonio  and  CARRILLO-LARCO, Rodrigo M.. Prevalence and trends of active and passive smoking among Peruvian adolescents. Rev. perú. med. exp. salud publica [online]. 2022, vol.39, n.2, pp.193-200.  Epub June 30, 2022. ISSN 1726-4634.


This study aimed to assess the trends of different smoking indicators among Peruvian adolescents. Additionally, we evaluated whether such trends were different by sex or among those without previous smoking history.

Materials and methods.

We analyzed the Global Youth Tobacco Survey (Global Youth Tobacco Survey 2007, 2014, 2019). Active smoking was defined according to smoking in the last 30 days. Passive smoking was assessed based on exposure to tobacco inside and outside the household, both overall and daily. Analyses considered the sample design.


A total of 17,047 records (9,869 in 2007, 3,424 in 2014, and 3,754 in 2019) were analyzed; the mean age was 14 years, and 49.9% were women. Previous smoking history was reported in 26.6% of the records; such prevalence fell from 45.2% (2007), to 25.3% (2014), and to 19.4% (2019, p-value for trend < 0.001), whereas active smoking fell from 17.1% (2007) to 8.7% (2014) and to 5.7% (2019). The overall prevalence of passive smoking inside the household fell from 24.7% to 12.9% and 10.4% (p-value <0.001), whereas the overall prevalence of passive smoking outside the household dropped from 46.3% to 39.4% and 36.3% (p-value <0.001) during the same period. The reduction of the smoking indicators was observed mainly among women than in men.


There is evidence of a sustained reduction in smoking indicators in Peruvian adolescents. Passive smoking outside the household continues to be common, calling for strengthening current tobacco control policies.
