Background: Tobacco exposure remains a significant public health issue, especially for pregnant women. Among other effects, it increases the risk of premature labor, low birth weight and small size for gestational age. Many countries have enacted public policies to curb tobacco exposure, for example by prohibiting smoking in public places. In 2006 and 2010 Peru enacted anti-tobacco laws that forbid smoking in public places, require the inclusion of prevention text and images in products and publicity, and prohibit sale to minors. The objective of this study was to assess whether the regulations related to the anti-tobacco legislation approved in Peru in 2008 were associated with a change in the birth weight, the risk of prematurity, and the risk of being small for gestational age (SGA). Methodology: A quasi-experimental study using data from the Peruvian Live Birth Registry was conducted. Children born to mothers residing in urban areas were the intervention group (impacted by the legislation), while children born to mothers residing in rural areas were considered the comparison group. Only singletons with information on birth weight and gestational age, born to mothers aged 12 to 49 years were included in the study. Newborns with birth weights greater than +4 standard deviations (SD) or less than -4 SD from the gestational age-specific mean were excluded. To measure the effect of legislation on birth weight a difference in differences analysis was performed. Results: A total of 2,029,975 births were included in the analysis. After adjusting for characteristics of the mother and the child, and for contextual variables, the implementation of the anti-tobacco law in Peru was associated with a reduction of prematurity incidence by 30 cases per 10,000 live births (95% CI: 19 to 42) and of SGA by 14 cases per 10,000 live births (95% CI: 0.40 to 28). However, the reform was not associated with changes in birth weight (mean change: -2.62 grams, 95% CI: -6.10 to +0.85). Conclusions: In concordance with studies conducted in other countries, the anti-tobacco law in Peru was associated with a modest reduction in prematurity and SGA, but did not have any association with birth weight.
