| Description | Journal: Experimental gerontology A number of cross-sectional studies have suggested that higher levels of sedentary (SB) are associated with worse cognitive abilities in older age. There is a paucity of longitudinal studies investigating this relationship utilizing objective SB. This study investigates the relationship between objective SB and future cognitive abilities in a cohort of older adults.A longitudinal study over 22.12±1.46months including 285 community-dwelling older adults across 14 regions in Taiwan was undertaken. Cognitive ability was ascertained using a Chinese version of the Ascertain Dementia 8-item Questionnaire (AD8) and SB captured by 7days accelerometer data. Multivariable negative binomial regression models adjusted for confounders were undertaken.274 community-dwelling older adults finished the study (age=74.6±6.2, % female=54.4%). At baseline, 20.1% (n=55), 48.5% (n=133) and 31.4% (n=86) of the sample engaged in high (>11h), medium (8-10.99) and low (<8h) of SB respectively. In the fully adjusted model, higher levels of SB were associated with an increased risk of worse cognitive ability at follow up (adjusted rate ratio (ARR)1.09 (95%CI:1.00-1.19), with the strongest relationship evident in those engaging in over 11h of SB (ARR 2.27 (1.24-4.16). The relationship remained evident after adjusting for depressive symptoms and physical activity.Our data suggests that objective SB, particularly when over 11h a day, is independently associated with worse cognitive ability over a two year period. Our data adds to the pressing reasons to reduced SB in older age. |
