However, the contribution of sedentary time to risk of mild cognitive impairment (MCI) remains unclear. This study assessed the association of SB with MCI in six low- and middle-income countries.
Methods: The Study on Global Ageing and Adult Health (SAGE) survey included 34,129 adults aged ≥50 years [mean (SD) age 62.1 (15.6) years; 51.7% females]. SB was self-reported and expressed as a categorical variable [<8 or ≥8 hours per day (high SB)]. The definition of MCI was based on the recommendations of the National Institute on Ageing-Alzheimer’s Association. Multivariable logistic regression analysis was conducted to assess the association between SB and MCI.
Results: The overall prevalence (95%CI) of MCI and high SB (i.e., ≥8h/day) were 15.3% (14.4%-16.3%) and 10.1% (9.0%-11.3%), respectively. After adjustment for potential confounders, being sedentary for ≥8h/day was associated with a 1.56 (95%CI=1.27-1.91) times higher odds for MCI. A one-hour increase in SB was associated with a 1.08 (95%CI=1.05-1.11) times higher odds for MCI.
Conclusion: Our study results highlight the need to further explore a sedentary lifestyle as a potential risk factor for MCI or subsequent dementia. Longitudinal and intervention studies are warranted to confirm/refute the current findings.
