The intervention consisted of 2 parts. After the baseline assessment, we showed the participants 3 animated health videos on a tablet computer. After a period of 6 months, free access to community information spots (InfoSpots) with an integrated digital health education platform was provided to the intervention villages. Participants in the control group did not receive the intervention. The primary outcome was the difference in disease knowledge between the intervention and control groups, 12 months after baseline. Data were collected using an open-ended questionnaire, with correct or incorrect answers before and after intervention.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Between April and May 2019, a total of 600 participants were recruited into the intervention (n=298, 49.7%) or control (n=302, 50.3%) groups. At baseline, no statistically significant differences in knowledge of the target diseases were observed. At 12 months after intervention, knowledge about HIV\/AIDS, TB, and T. solium (neuro)cysticercosis and taeniosis was 10.2% (95% CI 5.0%-15.4%), 12% (95% CI 7.7%-16.2%), and 31.5% (95% CI 26.8%-36.2%) higher in the intervention group than in the control group, respectively. In all 4 domains (transmission, symptoms, treatment, and prevention), an increase in knowledge was observed in all the 3 diseases, albeit to varying degrees. The results were adjusted for potential confounders, and the significance of the primary results was maintained in the sensitivity analysis to assess dropouts. The participants who reported using the InfoSpots in the 12-month assessment further increased their knowledge about the target diseases by 6.8% (HIV\/AIDS), 7.5% (TB), and 13.9% higher mean proportion of correct answers compared with the participants who did not use the InfoSpots.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Digital health education based on animated health videos and the use of free InfoSpots has significant potential to improve health knowledge, especially in rural areas of low- and middle-income countries.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Trial Registration<\/jats:title>\n                    <jats:p>ClinicalTrials.gov NCT03808597; https:\/\/clinicaltrials.gov\/ct2\/show\/NCT03808597<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>International Registered Report Identifier (IRRID)<\/jats:title>\n                    <jats:p>RR2-10.2196\/25128<\/jats:p>\n                  <\/jats:sec>","DOI":"10.2196\/37666","type":"journal-article","created":{"date-parts":[[2022,7,28]],"date-time":"2022-07-28T11:17:10Z","timestamp":1659007030000},"page":"e37666","source":"Crossref","is-referenced-by-count":25,"title":["Improving Health Knowledge Through Provision of Free Digital Health Education to Rural Communities in Iringa, Tanzania: Nonrandomized Intervention Study"],"prefix":"10.2196","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6084-0701","authenticated-orcid":false,"given":"Christine","family":"Holst","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6743-2818","authenticated-orcid":false,"given":"Dominik","family":"Stelzle","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2086-4909","authenticated-orcid":false,"given":"Lien My","family":"Diep","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5872-3832","authenticated-orcid":false,"given":"Felix","family":"Sukums","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8738-7903","authenticated-orcid":false,"given":"Bernard","family":"Ngowi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8168-5552","authenticated-orcid":false,"given":"Josef","family":"Noll","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3131-6983","authenticated-orcid":false,"given":"Andrea Sylvia","family":"Winkler","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1010","published-online":{"date-parts":[[2022,7,28]]},"reference":[{"key":"ref1","author":"Green, L","year":"1980","journal-title":"Health Education Planning: A Diagnostic Approach"},{"key":"ref2","year":"1988","journal-title":"Education for Health: A Manual on Health Education in Primary Health Care"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2458-12-80"},{"key":"ref4","unstructured":"The mandate for health literacyWorld Health Organization2022-06-08https:\/\/www.who.int\/teams\/health-promotion\/enhanced-wellbeing\/ninth-global-conference\/health-literacy"},{"key":"ref5","first-page":"266","volume":"17","author":"Gellert, P","year":"2015","journal-title":"Eur Health Psychologist"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.3389\/fpubh.2017.00194"},{"key":"ref7","unstructured":"Regional factsheets.
