Table 2 Adjusted prevalence estimates of impairments/epilepsy in children in study area

From: Childhood disability in Malawi: a population based assessment using the key informant method

Impairment/health condition Numbera Prevalence per 1000 (95% CI)a Prevalence per 1000 Rangeb No. Per million total populationc
Physical impairment 2247 6.6 (6.3–6.9) 5.8–7.6 3520
Hearing impairment d 1550 4.6 (4.4–5.8) 4.0–5.3 2453
Visual impairment 243 0.7 (0.6–0.8) 0.7–0.8 373
Intellectual impairment 1452 4.3 (3.8–4.2) 3.7–4.8 2133
Epilepsy 1258 3.7 (3.5–3.9) 3.3–4.3 1973
Multiple impairments 806 2.4 (2.2–2.6) 2.1–2.7 1280
Any impairment/epilepsy 5844 17.3 (16.9–17.7) 15.0–19.6 9066
  1. aThe number and prevalence estimates are adjusted based on the assumption that the prevalence of disability was the same among children who did and didn’t attend the examination camp. The denominator used to calculate the prevalence of impairments is the total number of children (338,235) living in the 8 traditional areas included in the study
  2. bThe prevalence range is based on sensitivity analysis assuming the proportion of non-attenders having an impairment/epilepsy was ±10% of the actual proportion among attenders
  3. cPer million total population of all ages, not population of children
  4. dIt was not possible to conduct Pure Tone Audiometry on 40% of children aged 5+ years and Ottoacoustic Emmission test results were used for those children
