The Longitudinal Study of Australian Children (LSAC) Child Health CheckPoint is 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 involves the younger LSAC children, born in 2003-4. Because the CheckPoint needs 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.

Are data available to others outside study team? Yes, The Longitudinal Study of Australian Children Wave 1-8 datasets, and the Child Health CheckPoint dataset, are available to researchers at no cost. Data access requests are co-ordinated by the National Centre for Longitudinal Data. Researchers need to obtain approval to use the LSAC-ADA dataset. More information is available at The CheckPoint Team also welcome collaboration requests from researchers to use digital images and biospecimens collected as part of the study.
Study focus (e.g. social development) 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 younger 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 study children are aged 11-12 years old and nearly-2000 children (and their parents) participated. 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.
Study type (e.g. randomised control trial, cohort, case-control) Cohort

Intergenerational (e.g. offspring)? LSAC: No, but parents complete questionnaires about themselves and child
CheckPoint: One of each child’s parents is also assessed
