Text: our data is available upon request by the corresponding author sierra clark <sierra.clark@mail.mcgill.ca>, the ihacc project manager ms. michelle maillet <michelle.maillet@mcgill.ca>, and the ihacc database manager ms. kaitlin patterson <kaitlin.patterson@mail.mcgill.ca>. the indigenous batwa community-members we work with are a small population (~700) of which our dataset is essentially a census. we do not have ethical approval to publicly release this dataset given the potential for reverse identification given the nature of our variables and size of the sample. furthermore, the batwa community-members we work with are partners in the research and we do not have their approval to publicly release this data. the study participants are an indigenous population that have in recent years undergone substantial political and social marginalization in uganda, and anonymity in their answers is a paramount concern of ours when doing research among our partner communities. we have gained approval however to make the relevant data available upon request to interested researchers. when, and if, the data is requested, a cleaned excel file of the relevant household and/or individual-level variables used to carry out the analysis (contingent on the request) will be provided.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
