Australians believe the number one health problem for children and teenagers is excessive screen time.
And while obesity comes in at number two, many parents see it as a community problem rather than related to their own children.
The findings are from the first Australian Child Health Poll, a quarterly national survey of 2000 households with and without children, conducted on behalf of Melbourne's Royal Children's Hospital.
Participants were asked about 29 issues, resulting in a top 10 of child health problems that included illegal drug use, which rated number one in lower-income households.
The poll's director Dr Anthea Rhodes said excessive screen time was perceived as a big health problem across all sections of the community, including by parents of very young children.
"Excessive screen time is not a traditional health problem, as such, so how do we provide care to children and their families struggling with what they have told us is a significant issue?" she asked.
The finding highlighted the need for innovation in public programs and communication initiatives, she said.
"While 48 per cent of parents rated obesity as a big problem for all children, only eight per cent rated it as a big problem for their own children.
"The implications of this are significant when one in four Australian children are overweight.
"If parents aren't recognising obesity as a problem in their own homes it might prove difficult to address the causes of childhood obesity."
