Prevalence and factors associated with faecal impaction in the Spanish old population.

ABSTRACT

Background: Faecal impaction (FI) is a common problem in old people living in nursing home. Its prevalence and associated factors remain unknown in the general population. Aim: To evaluate FI prevalence in the Spanish population older than 65 years and to assess the factors associated with it. Methods: A telephone survey was carried out of a Spanish population older than 65 years random sample (N = 1000). FI was assessed using a previously validated questionnaire. Results: A total of 28,128 calls were made; 1,431 subjects were eligible and 1,000 subjects were enrollled, mean aged 74.6 ± 7.3 (65­97); 57.5% were women. At least 53 people reported FI within the past year (5.3% (CI 95% 3.9­6.7%)). Only 0.03% met criteria for chronic constipation and faecal incontinence. FI-associated factors were constipation, female gender, reduced physical activity, and chronic renal failure (CRF). Conclusion: FI is a prevalent problem in old Spanish population. Constipation and female gender are the main associated factors; low physical activity and CRF appear to play also a significant role. Further studies are required to confirm this association.
