Abstract

Food shopping is an important aspect of maintaining independence and social interaction in older age (AgeUK, 2012, Food Shopping in Later Life). Carrying the shopping bags home, however, may pose higher fall risk. Carriage of UK-style shopping bag could cause exaggerated forward momentum during walking, increasing instability and, consequently, fall risk. The aim of the project was to examine the effect of carrying shopping bags on gait in healthy older females aged over 65 years. Following institutional ethics approval, nine older females (aged 71 (s 5.9) years) walked on a treadmill for 1 min at a self-selected speed carrying bags of varying loads and distributions (no bags, one 1.5-kg bag in each hand, one 3-kg bag in each hand, one 1.5-kg bag in preferred hand only, one 3-kg bag in preferred hand only; loads representing typical weight of essential shopping items) in a randomised order. Stride length, cadence, contact phase and left/ right imbalance characteristics were assessed using the Optojump Optical Measurement System (Microgate, Italy). Average and coefficient of variation values were recorded for each variable, to assess fall risk (Callisaya et al., 2010, Age and Ageing, 39, 191–197). Additionally, the load carried was quantified relative to handgrip strength (Takei Scientific Inst. Co. Ltd, Japan). A repeated measures analysis was used, and significance was set at P < 0.05. The heaviest load (3 kg in each hand, 6 kg in total) was 9.1% (range 7%–11%) of body mass and 14.3% (range 9.8%–22.8%) of handgrip strength. Average walking speed was 2.93 ± 0.54 km · h−1. Gait variables did not change with carrying shopping bags between any of the conditions for either average or coefficient of variation values. Gait parameters and their variability have been previously reported as important indicators of fall risks in older individuals, with changes in gait, suggesting poorer balance (Callisaya et al., 2010, Age and Ageing, 39, 191–197). In the present study, gait variables were not affected by carrying shopping bags, either in both hands or in one hand only, indicating that shopping does not increase fall risk in older females. The current findings support shopping for essentials as a safe activity for older females. These results could be used to reduce fear of falling and subsequently encourage essential items shopping, reducing social isolation as well as maintaining independence and increasing physical activity in older individuals (Hornyak et al., 2013, Archives of Physical Medicine and Rehabilitation, 94, 2529–2534).
