The prevalence of otitis media in 2–3 year old Cameroonian children estimated by tympanometry

Otitis media with effusion in Africa‐prevalence and associated factors: A systematic review and meta‐analysis

“…A significant association was also found for type 2 diabetes mellitus, 43 low CD4 cell count in Human Immunodeficiency Virus (HIV) infected adults 44 ( P = .03 for both) and allergic rhinitis in the age group of children <5 years 45 ( P < .001). Libwea et al 32,46 in Cameroon found an association between otitis media (OME included) and parental reporting of “current symptoms of upper respiratory tract infection” ( P = .001). Daycare attendance was evaluated by Asoegwu et al, 30 they found only a borderline effect on the prevalence rate of OME ( P = .05).…”

“…After screening of titles, abstracts and when required fulltexts, 1019 additional records were excluded. We retrieved 54 fulltext articles, from which 16 more were excluded (see reasons in T A B L E 1 Meta-analysis of prevalence of otitis media with effusion in Africa based (20 of these included in meta-analysis [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33], and 17 (44.7%)…”

“…This review included studies published from 1977 to 2019, involving participants from 11 countries, with all five major African geographic sub‐regions represented. Overall, 21 studies (55.3%) were community‐based (20 of these included in meta‐analysis 14‐33 ), and 17 (44.7%) hospital‐based (seven included in meta‐analysis 34‐40 ). Data were collected prospectively in 34 (89.5%) studies.…”

“…The role played by nasopharyngeal biofilm through shedding of inflammatory cytokines and planktonic bacteria 39 has been evoked as a predisposing factor for the development of OME. This would suggest that even in the absence of significant adenoid hypertrophy, children could still develop OME.Libwea et al32 found a significant association between the "parent notifying the presence of an ongoing upper respiratory tract symptom" and OM (P = .001). This association should be interpreted in the context of the study, where the term OM encompassed chronic suppurative otitis media and OME.…”

Assessing the causes of under-five mortality and proportion associated with pneumococcal diseases in Cameroon. A case-finding retrospective observational study: 2006–2012

“…We applied a retrospective case-finding observational study design using hospital registration data from the infectious disease surveillance sites hosted at the MCH in Yaoundé, Cameroon (Fig 1). As earlier described [13], the sites involved hospitals in both an urban and rural/semi-urban zones around Yaoundé, with a population of over 3.5 million inhabitants out of which 18% are children under-five [14].…”
