Longitudinal Study of Australian Children (LSAC)’s Child Health CheckPoint (CheckPoint-LSAC)

The Longitudinal Study of Australian Children (LSAC)'s Child Health CheckPoint was a one-off physical health check-in conducted during 2015-16 of the Growing Up in Australia study. The aim is to learn more about the health of young Australians as they pass through the ‘checkpoint’ between being children and teenagers. Therefore, it involved the younger LSAC children, born in 2003-4. Because the CheckPoint needed special equipment and skills, its staff are from the Murdoch Children’s Research Institute and are supervised by Growing Up in Australia’s senior health researchers.

LSAC’s main waves have happened every 2 years since 2004. Between the 6th and 7th wave, the 11 and 12 year olds took part in health activities which will enable researchers to learn about heart and lung health, fitness, strength, vision, diet, activity, and more.

Study focus

The Longitudinal Study of Australian Children (LSAC) is Australia’s largest and only nationally-representative children’s longitudinal study. The study commenced in 2004 with two cohorts (n≈10,000) – 0-1 year old infants (B cohort) and 4-5 year old children (K cohort). It is governed by the Department of Social Services, the Australian Institute of Family Studies (AIFS) and the Australian Bureau of Statistics (ABS). The cohorts are followed biennually, with a broad focus including health and development, education, family and parenting characteristics and socioeconomic environment. A new phase, LSAC’s Child Health CheckPoint is a one-off physical health and biospecimens module for the B cohort. It travelled around Australia in 2015-2016, collecting important information about children’s cardiovascular and respiratory health, fitness, strength, vision, hearing, diet, activity and more, as they transition from childhood to adolescence. The Child Health CheckPoint is conducted by researchers at the Murdoch Children’s Research Institute.

Sampling frame

LSAC had a two-stage clustered sampling design, first randomly selecting 10% of all Australian postcodes (stratified by state and urban/rural), then selecting children within those postcodes registered in Medicare Australia’s database and aged either 3-19 months old (B cohort) or 4-5 years old (K cohort).
CheckPoint: The B cohort families who completed a wave 6 home interview were eligible and invited to participate in CheckPoint.
