BMI and obesity in US blood donors: a potential public health role for the blood centre.

摘要: Obesity has been described as epidemic in the USA, with significant adverse consequences for incidence of diabetes and CVD, premature mortality reduced quality life(1–3). According to National Center Health Statistics data from Nutrition Examination Survey (NHANES) 2007–2008, obesity prevalence by age was: 27·5 % men 34·0 women ages 20–39 years; 34·3 38·2 40–59 37·1 33·6 60 years above(4). That study noted that upward trend observed US population over past 30 may be levelling off decade since 1999–2000. The Centers Disease Control Prevention have also used self-reported height weight Behavioral Risk Factor Surveillance System (BRFSS) estimate county-level obesity. Counties highest were concentrated West Virginia, Appalachian counties Tennessee Kentucky, much Mississippi Delta, southern belt extending across Louisiana, Mississippi, middle Alabama, south Georgia coastal regions Carolinas(5). However authors limitations both national surveillance mechanisms, including small sample size sex strata NHANES potential response bias BRFSS. Despite a moderate degree selection due volunteer health criteria, blood donors provide ongoing other health-related risk factors. Certainly such useful HIV Nile virus(6,7). Data on large numbers individuals are available continuously opposed episodic surveys. We not aware published BMI distributions among donors. Such information public surveillance, because body mass criteria define eligibility certain types collection (e.g. double red cell donation) prevention syncopal reactions. We therefore large, multicentre consortium centres perform descriptive analysis BMI. Although was modestly lower compared general population, demographic geographic differences surveillance.
