Susanto M, et al. - Researchers analyzed the patterns of sitting time with frailty in older age. They identified these patterns over 12 years in middle-aged women born in 1946–1951 from the Australian Longitudinal Study on Women's Health. They used information self-reported by these subjects on socio-demographic attributes, daily sitting time and frailty in 2001, and then every three years until 2013. Five sitting time trajectories were identified: low (27.5%); medium (41.5%; reference); increasing (8.2%); decreasing (18.0%); and high (4.9%). Individuals in the increasing and high trajectories had statistically higher chances of being frail, whereas, the low trajectory group was less likely to be frail. Overall, frailty in older age was predicted by patterns of sitting time over 12 years in middle-aged women.
