O7D.5 Subjective cognitive decline among us workers aged ≥45 years by occupation, BRFSS, 2015–2016

Abstract

Background Subjective cognitive decline (SCD) is one of the earliest noticeable symptom of dementia, including Alzheimer's disease. Some studies have shown that half of older adults with subjective memory complaints go on to develop more severe cognitive decline within 7-18 years. The objective of this study was to examine the prevalence of SCD among US workers and to identify occupations with a high prevalence of SCD, even after adjustment for common risk factors. Methods Data from the 2015-2016 Behavioral Risk Factor Surveillance System were used to examine the prevalence of SCD among US workers aged >45 years who were currently employed or were employed at some point in the past 12 months. SCD is defined as frequent confusion or memory loss within the previous 12 months. Only states (n=28) that collected data on both industry/occupation and cognitive decline were included in this study. Results The overall prevalence of SCD among US workers aged >45 years was 6.2%, and was higher for workers 65 years and older. The prevalence was significantly higher among Veterans (8.3%) compared to non-veterans (5.9%). 29.2% of those with SCD reported that they need assistance with day-to day activities and 35.1% had discussed confusion/memory loss with a healthcare professional. The prevalence of SCD was significantly lower among workers in management, business and financial operations, Healthcare practitioners and technical, and office and administrative support occupations. While workers in building and ground cleaning and maintenance, and personal care and service occupations had elevated prevalence of SCD. Conclusion Cognitive decline is an important public health issue affecting older workers and their ability to work. SCD prevalence is much higher among occupations that are less mentally challenging which indicates that interventions to improve or maintain cognitive functioning may help older workers to remain productive and in the workforce.
