early abstract:

Introduction: Indigenous populations in low-income regions are often the most acutely affected by social gradients that impact health, including high burdens of infectious disease. Using a mixed methods approach, this study characterized the lived experience of acute gastrointestinal illness (AGI) in an Indigenous Batwa population in southwestern Uganda.

Methods: Quantitative data analyses were conducted on data from three cross-sectional census surveys of Batwa conducted in January 2013 (n=583), January 2014 (n=569), and April 2014 (n=540).  Using a 14-day recall period, cases of AGI were defined as ≥3 loose stools or any vomiting in a 24hr period. These analyses were supplemented by qualitative data from key-informant interviews (n=11 interviews) and Batwa focus group discussions (n=61 participants).

Results: From the surveys, episodes of diarrhea and episodes of vomiting lasted on average 3.6 [95% CI 2.3-4.3] and 3.0 [95% CI 2.1-3.9] days, and cases experienced an average of 4.3 [95% CI 3.9-4.8] and 2.6 [95% CI 2.1-3.1] loose stools and vomiting episodes in 24 hours. Focus group participants and key informants indicated that episodes of AGI for Batwa were not limited to symptom-based consequences for the individual, but also had economic, social, and nutritional impacts.

Conclusions: Despite efforts to increase health literacy in disease transmission dynamics, risks, and prevention measures, the perceived barriers, and a lack of benefits still largely underscored adopting positive AGI prevention behaviors. This study moved beyond surveillance and provided information on the broader community-level burden of AGI and highlighted the current challenges and opportunities for improved uptake of AGI prevention measures for the Batwa
