Survey response rate was 98% (54/55). Overall, 57% perceived that using registry data saved research staff time in the current study, and 74% perceived that it would save time in future studies; 55% noted significant upfront time in developing a methodology for extracting registry data. Survey recommendations included simplifying data extraction processes and tailoring to the needs of the study, u

Using a continuous exposure variable that is measured with random error in a univariable linear regression model leads to regression dilution bias: the observed association between the exposure and outcome is smaller than it would be if the true value of the exposure could be used. A repeatability sub-study, where a sample of study participants have their data measured again, can be used to correc

Recently, King et al.1 assessed the effect of disability on mental health through bullying in adolescents using a causal mediation analysis method developed by Valeri and VanderWeele2 in which exposure–mediator interactions are allowed. In the latter method, one can only handle time-fixed exposure and mediator, and, for this reason, the authors only used the exposure in wave 5 and mediator (and ou

In healthcare, we have kept notes on people with diseases for over 4000 years. These have been a combination of subjective commentary and objective measurement. In the past 30 years recording data on patients has been systematised through disease registries and electronic patient records (EPR). We now have extensive registries in many diseases with robust cross-sectional and more importantly, long

Work histories generally cover all jobs held for ≥1 year. However, it may be time and cost prohibitive to conduct a detailed exposure assessment for each such job. While disregarding short-term jobs can reduce the assessment burden, this can be problematic if those jobs contribute important exposure information towards understanding disease aetiology.

There is a growing interest in using health care (HC) data to produce epidemiological surveillance indicators such as incidence. Typically, in the field of cancer, incidence is provided by local cancer registries which, in many countries, do not cover the whole territory; using proxy measures from available nationwide HC databases would appear to be a suitable approach to fill this gap. However, i

The association between socio-economic position and health is believed to be mediated, in part, by psycho-social comparison of one’s situation with that of others. But with whom? Possibilities include family, friends, elites, or even those in other countries or in previous times. So far, there has been almost no research on whether the reference point matters.

Obesity defined as increased BMI is commonly associated with higher revision rates following total knee arthroplasty (TKA). We examined the effect of BMI on the rate of revision after TKA, for both infection and other reasons, and analyzed weight and height separately to provide better understanding of the risk profile.

In recent years, epidemiologists have increasingly sought to employ genetic data to identify ‘causal’ relationships between exposures of interest and various endpoints – an instrumental variable approach sometimes termed Mendelian randomization. However, this approach is subject to all of the limitations of instrumental variable analysis and to several limitations specific to its genetic underpinn

Physical activity might reduce the risk of developing dementia. However, it is still unclear whether the protective effect differs depending on the subtype of dementia. We aimed to investigate if midlife physical activity affects the development of vascular dementia (VaD) and Alzheimer’s disease (AD) differently in two large study populations with different designs.

Griffen and colleagues article on extrapolating information from national registries showcases the importance of clinical health registries in identifying relationships between factors that can lead to adverse health outcomes.
