Editors' Note:
Over many years, there has been a heavy reliance on self-reported energy intake and physical activity data in human observational and epidemiological studies relating to obesity. Whilst knowledge in the field of energy balance has certainly advanced as a result of these studies it has been clear for some time that self-report data can be highly inaccurate. Energy balance assessment is a crucial methodological issue for the field, since the potential inaccuracies of self-report data make the findings of many studies questionable at best and sometimes incorrect and misleading. This has potentially serious implications for health care policy and clinical decision making. The paper by Dhurandhar and colleagues, on behalf of the Energy Balance Measurement Working group, clearly and succinctly examines this issue. Dhurandhar and colleagues highlight that ‘bad data lead to bad conclusions’. They make a plea for resources to be directed at the development of objective, precise and accurate measures of energy balance. This call is long overdue and attention to this issue can only enhance the quality of evidence-based recommendations for the future. John Brameld & David Stensel (Associate Editors), November 2014
Abstract
Energy intake (EI) and physical activity energy expenditure (PAEE) are key modifiable determinants of energy balance, traditionally assessed by self-report despite its repeated demonstration of considerable inaccuracies. We argue here that it is time to move from the common view that self-reports of EI and PAEE are imperfect, but nevertheless deserving of use, to a view commensurate with the evidence that self-reports of EI and PAEE are so poor that they are wholly unacceptable for scientific research on EI and PAEE. While new strategies for objectively determining energy balance are in their infancy, it is unacceptable to use decidedly inaccurate instruments, which may misguide health-care policies, future research and clinical judgment. The scientific and medical communities should discontinue reliance on self-reported EI and PAEE. Researchers and sponsors should develop objective measures of energy balance.
