| Abstract: | The objective of this work was to summarise and evaluate the evidence showing that physical activity is a protector factor as regards falls in older people. Relevant studies were identified through a systematic search in the MEDLINE and Cochrane Library, under the keywords of accidental fall/numerical data and risk factors, and with the bibliographies of retrieved papers. The combined odds ratio (OR) 95% confidence interval] for physical activity was 0.75 0.64, 0.88] with moderate heterogeneity (I 2?=?33%). For fall injury, it was 0.59 0.47, 0.74] and, for falls in general, it rose to 0.94 0.76, 1.17] with nil heterogeneity. The combined OR for sedentary factors was 1.14 1.10, 1.82] with moderate heterogeneity (I 2?=?36%). Regular physical activity in daily life yields significant reduction in falls in older people, especially falls with injuries. |
