BACKGROUND: The multifactorial nature of falls is well known, and several studies on falls in the elderly have reported that laxatives can be a risk factor, but without attempting to discuss possible mechanisms to explain this role. OBJECTIVE: We aimed to isolate studies in which the risk factors for falls in the elderly related to laxatives have been evaluated and to carry out a meta-analysis combining the results of all identified good-quality studies. METHODS: Systematic literature review using the keywords 'accidental fall/numerical data' and 'risk factors'. This was followed by a manual search for articles cited in the previously identified publications. Articles were analysed if they had study populations aged ≥60 years, reported on falls occurring in everyday life, were observational or interventional studies that identified laxatives as a risk factor for falls, and were written in French or English. Articles of this type that were considered to be of good quality were included in the meta-analysis. RESULTS: 3747 indexed articles published between 1981 and 2007 were identified. Of these, seven articles met all inclusion criteria and were analysed. The odds ratio (95% CI) for the association between use of laxatives and fall occurrence in subjects participating in the good-quality trials (n = 4) included in the meta-analysis was 2.03 (1.52, 2.72). This result was statistically homogeneous (percentage of the total variation across studies due to heterogeneity [I2] = 0). CONCLUSIONS: Elderly subjects treated with laxatives were twice as likely to fall compared with non-laxative users. The causal relationship was probably not directly attached to a side effect of the substance used, but rather a reflection of other pathologies (e.g. older age, confinement to bed, concomitant Parkinson's disease) that may themselves cause falls.
