SEVEN out of 10 adults admitted to physically hurting children in their care.
This represents approximately 72 per cent of the total adult population in the country.
The percentage meant that 370,535 of the total 514,632 adult population based on the last census were violent towards their children.
The findings were released in a publication "Children in Fiji 2011: An Atlas of Social Indicators".
"While information pertaining to where this happened is unknown, this reveals children's continuing vulnerability in the presence of adults, either in their immediate families or when living with relatives," the publication stated.
The atlas was based on core social indicators provided by UNICEF and government partners with data sources from the 2007 census.
"Some 37 per cent of children aged 16 to 17 said they had experienced physical abuse from an adult home in the past month," the report stated.
The Fiji Bureau of Statistics however, reported a decline in child physical abuse cases from 232 cases in 2008 to 170 cases in 2009.
Permanent secretary for Strategic Planning, National Development and Statistics Pita Wise said there were initiatives in the pipeline such as the National Child Protection Policy that would ensure promising strides towards child protection.
UNICEF regional representative Daniel Toole said Fiji needed to invest in cost-effective responses towards the reduction of those incidences with the promotion of children's rights on the agenda.
