Our Mission

Our mission is to transform health systems to address the changing health needs of children and young people. Chronic, non-communicable diseases account for most disability adjusted life years lost (DALYS) among children and young people in high-income countries. Obesity, respiratory diseases like asthma, and neuropsychiatric disorders like anxiety and depression are among the most common causes of morbidity.

The Population Child Health research group works across Sydney Children’s Hospitals Network and UNSW to understand what determines poor health in children and young people. We want to develop and evaluate scalable, integrated intervention packages that can be delivered by existing practitioners. Our focus is on translational research that will have a direct impact on the lives of children. We focus on children and young people whose voices often go unheard, such as Aboriginal and Torres Strait Islander children, children from culturally and linguistically diverse (CALD) backgrounds, children from refugee families, and children living in socioeconomic disadvantage or out-of-home care.
