Objectives : to assess prevalence of mild cognitive impairment (MCI) and risk factors
associated with cognitive impairment in hospital staff with pre-retirement period.
Methods : This study was cross sectional descriptive performed in Ramathibodi Hospital
with staff who were between 50-60 years old that pre-retirement period. Sample size
was 260 of total 1,211 staff in the hospital. They were given face-to-face interview for
demographic data, Hospital anxiety and depression scale-Thai version. Depression or
anxiety was definded as tests’s score of 11 and abone which was the exclusion eriteria
and the Montreal Cognitive Assessment (MoCA) Thai-version. Mild cognitive impairment
was defined as a test’s score of 24 or less.
Results : Prevalence of mild cognitive impairment was 30.8%. The significant associated
risk factors were sex, education, occupation and smoking. Multiple logistic regression
showed that significant risk factors related to mild cognitive impairment (p < 0.05) were
year of education less than 6 (OR = 2.70, 95% CI = 1.21-6.01) and semiskilled/ unskilled
occupation (OR = 2.55, 95% CI = 1.28-5.06) and depressive scores from Hospital Anxiety
and Depression Scales (HADS) (OR= 1.139, 95%CI 1.023-1.267)
Conclusions : The study found that the tendency to have MCI in hospital staff with
pre-retirement period is 30.87%. In the meantime, two factors that influence MCI
tendency were identified, namely education level, occupation type and depressive
scores. Therefore, preventive program should be developed in order to reduce risk of
MCI to become dementia, accordingly.
