Concurrent decline in teenage fertility rate and binge drinking? An observational study across 45 nations.

The association between adolescent binge drinking and fertility rates diminishes when accounting for country-specific time trends. Given the lack of clear mechanisms linking binge drinking to trends in fertility rates rather than shorter-term changes, the association likely reflects broader secular trends. Binge drinking may be involved in teen pregnancy and childbirth in individual cases but it does not explain recent developments in teenage fertility rates.
