Data Description

This dataset contains spirometry measurement data collected from children and adolescents living with perinatal HIV. The participant was instructed to take a deep breath and breathe out as much air as quickly as possible into a spirometer. Spirometry measurement tests were repeated approximately every 6 months for up to 3 years.

Access to this dataset is restricted to protect study participants. Researchers wishing to obtain the dataset must submit an access request, outlining the research purpose in which it will be used, ethics approvals obtained, and list the specific variables requested. The request will be evaluated by a study committee and, if approved, a data transfer agreement for signing prior to being provided with the dataset. Any participant-identifiable information contained within the dataset will be removed or disguised prior to being provided.
