biomarkers in many of the large, population-based health and social surveys such as Understanding Society and the English and Scottish Health Surveys. This growth in collecting simultaneous biological and social data, longitudinally (repeatedly over a period of time from the same individuals) and across the life course, is key if we are to continue to advance our knowledge of the biological and health impacts of our environments and society. So far, much of the evidence is based on cross-sectional data (data collected at only one point in time, rather than repeatedly) or where we have biomarkers measured once, but with repeat social data for the same individuals over a number of years. However, studies such as Understanding Society are beginning to provide us with biological measures from the same individuals measured over several years. This type of longitudinal data will help us to better understand how our bodies change over time and the relative importance of different stages of our lives (for example, childhood versus young adulthood).
The increase in data linkage to routinely collected data records (e.g. education surveys linked to health records) is also allowing us to research the long-term health consequences of social and economic circumstances, even after studies and surveys have stopped running. It may also be possible in the future to carry out such linkage between health and social data with biomarker data, collected when visiting your doctor for example. There are obviously many ethical, financial and practical challenges and questions linked to these types of data linkage ideas, but they offer possibilities to broaden our knowledge of the social determinants of health. It is also becoming slightly more common to see intervention studies including biomarker measures that will allow us to see the physiological effects that will be occurring long before we ‘feel’ or see changes in health, perhaps changing how we can demonstrate ‘effectiveness’.
social epidemiology are often multidisciplinary pursuits, or at least many of us arrive working in these fields from multiple academic and professional backgrounds. However, there remains a need for greater cross-discipline collaborations to help us better study the links between our social, cultural, environmental and political circumstances and our wellbeing, health and physiology. I am keen to see more biologists, epidemiologists, social scientists, statisticians etc. work together on these projects. I trained as a biologist up to and including PhD-level before moving into public health and social epidemiology. One of the key roles I now fulfil (and enjoy) is acting like a match-maker, and sometimes a translator, for lab scientists and social and public health scientists to come together to work on research projects. This type of role is becoming ever more common, especially in public health where we need a mix of specialists and more of these generalists, with expertise across a range of disciplines. This is by no means an easy role to play as it can mean being the conduit to link specialist researchers and/or practitioners together without then being able to play a leading role in the development and implementation of these research studies. It’s the ‘jack of all trades, master of none’ issue. However, without these generalists with interests and expertise that span multiple disciplines we continue to risk limiting innovation and interaction to help impact on areas like health inequalities. Perhaps the saying ‘a jack of all trades is a master of none, but oftentimes better than a master of one’ is a better representation of what I’m aiming for. I hope.
