In this episode we talk to Dr Melissa Oldham about why alcohol consumption appears to have fallen amongst children and young people over recent decades. Evidence shows that overall falls in UK consumption have been driven entirely by young people abstaining more frequently from alcohol, and when they do drink drinking less, and less often. However, the reasons for the these falls remain uncertain. For instance what role have changes in parenting, availability, social media and other cultural shifts affecting children and young people had, and what can we learn from this? Dr Melissa Oldham is a Research Fellow at University College London's Tobacco and Alcohol Research Group.
