[The prevalence of urinary incontinence in a population over 60 treated in primary care]

To determine the prevalence of urine incontinence (UI) among the over-60 population treated in primary care, identifying the types and associated epidemiological factors.

Descriptive and crossover.

Primary care.

Sample of 400 people aged 60 or over, stratified by sex and chosen from those who attended their health centre spontaneously for a consultation.

Age, sex, chronic illnesses, treatments, previous childbirths, grade of immobility and presence or absence of involuntary discharge of urine. If the reply was positive: frequency, characteristics and evolution of UI, and prior consultations on the problem were also measured. 400 people (254 women and 146 men). Mean age: 71 (SD = 7.3 years). 145 people (36.2%) recognised they had UI. 43.3% of women and 23.9% of men (p < 0.001) were incontinent. UI prevalence increased with age: 31.7% among the 60-69 year old group; 35% among the 70-79 group; and 53.3% in those over 80. Among women the most common types are stress and urge incontinence, whereas among men the most common are urge and overflow UI. UI prevalence is greater among women with previous childbirths and among immobile patients. Of the 145 people who recognised their UI, only 31 (21.3%) had previously consulted the doctor on this problem, although men had consulted significantly more than women (40% vs. 15.4%; p < 0.01).

Over a third of the people over 60 in our clinics suffer from UI. Prevalence increases with age and is greater among women, especially if there is a history of childbirth. Urge UI predominates among men and stress UI among women. Most people with UI do not consult concerning their problem, for which reason, so as to identify it and adopt corrective measures, women especially must be systematically asked about the symptom.
