It has been suggested they are a precursor of mild cognitive impairment MCI or dementia and an early indicator of cognitive decline. Vascular risk factors have an important role in the development of dementia and possibly MCI. We therefore aimed to test the hypothesis that vascular risk factors were associated with SMC independent of psychological distress in a middle-aged community-dwelling population. Methods A cross-sectional analysis of baseline data from the 45 and Up Study was performed. This is a cohort study of people living in New South Wales Australia and we explored the sample of 45 532 participants aged between 45 and 64 years. SMC were defined as fair or poor on a self-reported five-point Likert scale of memory function. Vascular risk factors of obesity diabetes hypertension hypercholesterolemia and smoking were identified by self-report. Psychological distress was measured by the Kessler Psychological Distress Scale. We tested the model generated from a randomly selected exploratory sample n 22 766 with a confirmatory sample of equal size. Results 5 479 45 532 12 of respondents reported SMC. Using multivariate logistic regression only two vascular risk factors smoking OR 95 CI - and hypercholesterolaemia OR 95 CI - showed a small independent association with SMC. In contrast psychological distress was strongly associated with SMC. Those with the highest levels of psychological distress were 95 CI - times more likely to have SMC than the non-distressed. The confirmatory
