Text: We find no evidence of an effect of the Teenage Pregnancy Strategy on rates of teenage pregnancies or births in England between 1999 and 2016 . Analysis of England - only data showed a clear change in trend during the Strategy period , consistent with previous observations ( Wellings et al . , 2016 ) . However , the similar changes observed in other UK , European and English - speaking countries suggest that England may have seen a similar fall in teenage pregnancy in the absence of the Strategy . This finding of little , if any , impact was consistent across two methods using different datasets , and was robust to sensitivity analyses .<|eot_id|><|start_header_id|>assistant<|end_header_id|>
