Falls are the leading cause of injuries in women across all ages. While yoga has been shown to increase balance, it has also been associated with injuries due to falls during practice. This study aimed to analyse whether regular yoga or meditation practice is associated with the frequency of falls and fall-related injuries in upper middle-aged Australian women.Women aged 59–64 years from the Australian Longitudinal Study on Women's Health (ALSWH) were queried regarding falls and falls-related injuries; and whether they regularly practiced yoga or meditation. Associations of falls and falls-related injuries with yoga or meditation practice were analysed using chi-squared tests and multiple logistic regression modelling.Of 10,011 women, 4413 (44.1%) had slipped, tripped or stumbled, 2770 (27.7%) had fallen to the ground, 1398 (14.0%) had been injured as a result of falling, and 901 (9.0%) women had sought medical attention for a fall-related injury within the previous 12 months. Yoga or meditation was practiced regularly by 746 (7.5%) women. No associations of falls, fall-related injuries and treatment due to falls-related injury with yoga or meditation practice were found.No association between yoga or meditation practice and falls or fall-related injuries have been found. Further studies are warranted for conclusive judgement of benefits and safety of yoga and meditation in relation to balance, falls and fall-related injuries.

Allergenic extracts intended for the treatment of type I allergies by specific immunotherapy are complex mixtures of molecules, obtained from biological materials known to exhibit some variability. Today, multiple methods are available for extensive characterization of allergenic extracts and documentation of their consistency. (C) 2011 Elsevier Masson SAS. All rights reserved.
