Estimating the changes in energy flux that characterize the rise in obesity prevalence

摘要: Background: The daily energy imbalance gap associated with the current population weight gain in obesity epidemic is relatively small. However, substantially higher body weights of populations that have accumulated over several years are a total expenditure (TEE) and intake (TEI), or flux (EnFlux = TEE TEI). Objective: objective was to develop an equation relating EnFlux adults for estimating rise epidemic. Design: Multicenter, cross-sectional data from doubly labeled water studies 1399 aged 5.9 ± 18.8 y (mean SD) were analyzed linear regression models natural log (ln) as dependent variable ln independent variable, adjusted height, age, sex. These equations compared those children applied trends gain. Results: positively related (β 0.71; 95% CI: 0.66, 0.76; R2 0.52), This slope significantly steeper than previously described 0.45; 0.38, 0.51). Conclusions: relation suggests substantial increases TEI driven past 3 decades. Adults proportional same increase intake, mostly because fat content being gained. will not be reversed without large reductions physical activity, both.
