Abstract
ObjectiveTo validate energy intake (EI) estimated from a pre-coded food diary (PFD) against energy expenditure (EE) measured with a valid physical activity monitor (SenseWear Pro3 Armband) and to evaluate whether misreporting was associated with overweight/obesity in a group of elderly men.MethodsForty-seven healthy Norwegian men, 60–80 years old, completed the study. As this study was part of a larger intervention study, cross-sectional data were collected at both baseline and post-test. Participants recorded their food intake for four consecutive days using food diaries and wore SenseWear Pro3 Armband (SWA) during the same period. Only participants with complete data sets at both baseline and post-test were included in the study.ResultsThe group average EI was 17% lower at baseline and 18% lower at post-test compared to measured EE. Mean difference from Bland-Altman plot for EI and EE was −1.5 MJ/day (±1.96 SD: −7.0, 4.0 MJ/day) at baseline and −1.6 MJ/day (−6.6, 3.4 MJ/day) at post-test. The intraclass correlation coefficient (ICC) was 0.30 (95% CI: 0.02, 0.54, p = 0.018) at baseline and 0.34 (0.06, 0.57, p = 0.009) at post-test. Higher values of underreporting was shown among overweight/obese compared to normal weight participants at both baseline and post-test (p≤ 0.001), respectively.ConclusionsThe results indicate that the PFD could be a useful tool for estimating energy intake in normal weight elderly men. On the other hand, the PFD seems to be less suitable for estimating energy intake in overweight/obese elderly men.
Highlights
In European countries there is a growing elderly population, and it is predicted that the current 15% of the total population aged 65 or more years will increase to more than 25% by 2050 [1]
SenseWear Pro3 Armband (SWA) has been validated in adult populations, and the results showed underestimation of total EE with 4.7% and 12.5%, compared to estimates derived from doubly labelled water [19,20] and 9% compared to estimates derived from indirect calorimetry [26]
The accuracy of the reported energy intake (EI) was assessed partly based on the 95% confidence limits of agreement between EI and EE measured by the doubly labelled water (DLW) method as proposed by Black [29]
Summary
In European countries there is a growing elderly population, and it is predicted that the current 15% of the total population aged 65 or more years will increase to more than 25% by 2050 [1]. A similar growth rate of the elderly population is predicted in America and Australia [2,3]. As this is the fastest growing segment of the population, it becomes more apparent that investments in aging and health, including nutrition is essential. A general finding in dietary studies is the tendency to underreport energy intake, and this is found both among children and adolescents [11,12], adults [13,14] as well as elderly [15,16]. A Danish cohort study, examining men at the mean ages of 20, 33, 44, and 49, has shown that underreporting was more prevalent in obese men than those who were not obese [14]
