Participants underwent standardised vision, hearing and musculoskeletal impairment assessment to assess need for distance glasses, hearing aids, wheelchairs. Participants with moderate or worse impairment and\/or self\u2010reported difficulties in functioning were also asked about their self\u2010reported AP need.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>6.5% (95% CI 5.4\u20137.9) in India and 1.9% (95% CI 1.5\u20132.4) in Cameroon of the population needed at least one of the three APs based on moderate or worse impairments. Total need was highest for distance glasses [3.7% (95% CI 2.8\u20134.7) India; 0.8% (95% CI 0.5\u20131.1), Cameroon] and lowest for wheelchairs (0.1% both settings; 95% CI 0.03\u20130.3 India, 95% CI 0.04\u20130.3 Cameroon). Coverage for each AP was below 40%, except for distance glasses in India, where it was 87% (95% CI 77.1\u201393.0). The agreement between self\u2010report and clinical impairment assessment of AP need was poor. For instance, in India, 60% of people identified through clinical assessment as needing distance glasses did not self\u2010report a need. Conversely, in India, 75% of people who self\u2010reported needing distance glasses did not require one based on clinical impairment assessment.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>There is high need and low coverage of three APs in two low\u2010and middle\u2010income settings.
