Title Experienced temperature and health
Post date 09/04/2018
C1 Background and Explanation of Rationale This study is motivated by questions around the impacts of cold domestic conditions on health. In the UK, the primary evidence for a link between cold and poor health is the peak in mortality which occurs in winter, as recorded in excess winter mortality statistics. To date, there have been a limited number of large scale studies into the population level links between cold exposure and health. The study makes use of UK Biobank data, and in particular temperature data taken from an wristband activity monitor worn by over 100,000 Biobank participants for a week. Pilot studies showed that the temperature recorded by the wristband is a determined by a mixture of ambient environmental temperature and heat from the wrist – a quantity which has been called ‘experienced temperature’ – a concept adapted from Kuras et al. (2015). Following a large data processing exercise to down-sample the 100k data files to produce the experienced temperature time series, associations between demographics/health condition data and the experienced temperature will be tested.
C2 What are the hypotheses to be tested?

1) No significant differences in experienced will be measured as a function of demographics.
2) A weak association between low experienced temperature and health conditions associated with excess winter deaths is expected.
3) A stronger association between low experienced temperature and health conditions associated with excess winter deaths and low household income.

C3 How will these hypotheses be tested? * Multilevel Model/Multiple regression
