Background: The Frontal Assessment Battery (FAB) has been shown to be useful in evaluating frontal dysfunction. There is a paucity of studies validating cutoffs in the early cognitive impairment. We aim to validate the Chinese FAB in Asian subjects with mild cognitive impairment (MCI) and early dementia. Methods: Eighty subjects with MCI and mild dementia and 100 cognitively healthy community subjects were studied. ROC analysis was done to determine the Chinese FAB’s optimal cutoff scores for age- and education-adjusted subgroups. Results: Chinese FAB scores were significantly lower in early cognitive impairment compared with cognitively normal controls. The optimal cutoff score was 12/13 (sensitivity 92%, specificity 78.7%). A similar cutoff score was obtained following age-adjustment and for subjects with <6 years’ education. Of note, the optimal cutoff for subjects with ≧6 years’ education was 13/14 (sensitivity 91.8%, specificity 70.3%), an improved diagnostic performance compared to the earlier reported 11/12 cutoff. In comparison, the Mini-Mental Status Examination (MMSE) had lower rule-out accuracy (77% sensitivity, 91.2% specificity). The combination of the Chinese FAB and MMSE was superior to either test in isolation. Conclusion: The education-adjusted Chinese FAB has good diagnostic performance, which can supplement the MMSE in early cognitive impairment evaluation with construct differences observed between the Chinese FAB and MMSE.

Study Objectives: To determine the associations of self-reported sleep quality and duration with health-related quality of life (HRQOL) in older Chinese. Methods: We analyzed community-based cross-sectional data of 5,539 individuals aged 60 years and older in the Weitang Geriatric Disease Study. Information of sleep quality and duration were self-reported through participants' responses to predefined questions; HRQOL data were collected by using the European Quality of Life-5 Dimensions (EQ-5D). We estimated the associations of sleep quality and duration with the EQ-5D index and visual analog scale (VAS) scores using linear regression models. The associations between sleep quality and duration and EQ-5D-detected health problems were modeled using logistic regression. Results: In multiple linear models adjusting sociodemographic factors, health conditions, and lifestyle habits, both EQ-5D index and VAS scores declined with deterioration of sleep quality. The coefficients for poor and intermediate sleep quality were −0.053 (95% confidence interval [CI]:−0.065, −0.042) and −0.022 (95% CI: −0.030, −0.013), respectively, in relation to EQ-5D index score. They were −5.2 (95% CI: −6.7, −2.4) and − 3.8 (95% CI: −4.9, −2.7) in modeling the EQ-5D VAS score. HRQOL declined as sleep duration decreased below 7.01 hours or exceeded 8.01 hours, though most of the associations did not reach statistical significance. In multiple logistic models, poor sleep quality was associated with problems of mobility, pain/discomfort, and anxiety/ depression; short sleep duration was associated with mobility problems. Conclusions: Poor sleep quality and extreme sleep durations appeared to be negatively associated with HRQOL in older Chinese adults.
