Socio-demographic disparities in the utilisation of general practice services for Australian children - Results from a nationally representative longitudinal study.

OBJECTIVE: This study aimed to investigate the pattern of general practice services utilization for Australian children and to examine socio-demographic disparities in general practitioner (GP) visits.

METHODS: We used the linked data from the nationally representative Longitudinal Study of Australian Children (LSAC) and the Medicare Australia claims data record. We used survey negative binomial and logistic regression to examine the socio-demographic factors associated with the utilisation of general practice services.

RESULTS: The average number of annual GP visits gradually declined from 7.0 at 0-1 year old to 2.4 at 5-8 years (p< .001 for trend) in the infant cohort and from 3.5 at 2-4 years to 2.0 at 9-12 years (p < .001 for trend) in the child cohort. Girls were more likely to visit GPs than boys at 0-1 year old in the infant cohort (RR = 1.06, 95%CI: 1.02-1.11) and at 2-4 years in the child cohort (RR = 1.09, 95%CI: 1.04-1.14), but there were no differences at 2-4 to 5-8 year age periods in the infant cohort and at 5-8 to 9-12 year age period in the child cohort. Children from non-English speaking background were more likely to have a greater number of GP visits compared with their counterparts from English-speaking and Indigenous background up to eight year old in both cohorts (all p < .001). Children from families with the higher socio-economic position, children without private health insurance and children living in non-metropolitan were less likely to have GP consultations in both cohorts. Fair or poor parent-rated health status was associated with greater number of GP visits.

CONCLUSION: Socio-demographic disparities existed in the utilisation of general practice services and varied at different age periods. Family socio-economic position, private health insurance coverage and region of residence strongly associates with the utilisation disparities over all age period. Further policy interventions are called to minimise the disparities in GP utilisation for children in Australian context.
