Adolescents frequently miss out on important health care due to barriers in accessing services. These can include cost, concerns about confidentiality, or simply not knowing where to go or how to access services. To combat this problem many governments globally have developed school-based health services (SBHS) to provide accessible primary care for low-income families. These services aim to promote a healthy lifestyle and enable students to have a better start in life. The use of SBHS across Australasia offers potential for increasing and improving the delivery of primary care to adolescents, especially for those experiencing social disadvantage.
