Background. Asymptomatic bacteriuria (ASB) is common among the elderly in institutionalcare, but less is known about its prevalence among the elderly living in community settings.Knowledge of the prevalence of ASB in this population could contribute to a reduction inunnecessary use of antibiotics.Objective. To study the prevalence of ASB and associated health and social factors in apopulation of elderly people, aged 80 and over, in a community setting.Design. A cross-sectional study.Setting. The catchment area of a primary health care centre in a Swedish middle-sized town.Method. All residents, aged 80 and over, except for those in institutional living, were invited. Astructured interview was carried out and urinary culture obtained.Results. ASB was found in 14.8% of the participants, in 19.0% of the women and 5.8% of themen. In women independent associations with ASB were found for urinary incontinence (OR:2.99, CI: 1.60–5.60), reduced mobility (OR: 2.68, CI: 1.42–5.03) and oestrogen treatment (OR: 2.20,CI: 1.09–4.45).Conclusion. Bacteriuria is common among the elderly living in non-institutional communitysettings, especially among women, although not as common as among the elderly in institutionalsettings. A woman over 80, with urinary incontinence, and needing support to walk has arisk of nearly 50% of presenting with ASB, a condition about which there is consensus not totreat with antibiotics. This should be borne in mind when examining patients with diffusesymptomatology and an accidental finding of bacteriuria.
