Notes

Large, well-designed prospective cohort studies are very useful for identifying risk factors for chronic disease. UK Biobank is one such study, made up of about 500,000 people who have been extensively characterized for a wide range of phenotypes. However, UK Biobank is unusual in that only 6% of people invited to take part in its initial survey agreed to do so. UK Biobank participants tend to have a more favourable risk factor profile and lower mortality than the general population of the same age. The low response rate has led to debate as to whether findings of links between risk factors and disease from UK Biobank are likely to be generalizable. We compared associations between risk factors for chronic disease and mortality in UK Biobank with nationally representative cohort studies which had conventional response rates. Associations of a wide range of risk factors with mortality outcomes showed close agreement between studies. Risk factor associations in UK Biobank seem to be generalisable

The relationship of cognitive function and negative emotions with morbidity and mortality: an aetiological investigation

The proposed research aims to understand why it is that poorer cognitive function and negative emotional factors are typically associated with poorer health and increased mortality. We shall use health outcome data to examine how all-cause mortality and incident cancer and cardiovascular disease (CVD)vary according to prior cognitive function and negative emotions. We shall investigate the extent to which relationships we find between cognition, emotions and these health outcomes are explained or modified by physical, biological, genetic, behavioural, and socio-demographic factors. Genetic analyses will incorporate multivariate genome-wide complex trait analysis and polygenic prediction of these relationships. Poorer cognitive function and negative emotional states and traits have been shown to increase mortality but the reasons for this are unclear. We anticipate that the proposed research will: 1) show us how mortality and morbidity from common health conditions vary according to prior cognitive abilities and emotional factors; 2) reveal potential mechanisms whereby poorer cognition and negative emotion increase risk; and 3) identify whether other characteristics can increase or reduce the risk of ill health in those with poorer cognition and negative emotions. This information could help inform intervention strategies for preventing or treating common health conditions. Using data on cognitive function and negative emotions together with data collected on health outcomes, scientists at the Centre for Cognitive Ageing and Cognitive Epidemiology will examine whether cognitive performance and emotional states predict risk of all-cause mortality and the onset of cancer and CVD. They will investigate whether other characteristics, such as lifestyle, socio-demographic, physical, behavioural or biological factors, help to explain any links between cognitive function and emotions and these health outcomes. They will estimate degree of genetic sharing between: 1) cognitive function/emotions and these characteristics, and 2) cognitive function/emotions and health outcomes. The full cohort
