Away from home meals: associations with biomarkers of chronic disease and dietary intake in American adults, NHANES 2005-2010.

摘要: Away from home (AFH) meals are known to be energy-dense and of poor diet quality. Both direct indirect exposure (for example, neighborhood restaurant density) AFH have been implicated as contributors higher body weight adverse health outcomes. To examine the association frequency eating fast-food with biomarkers chronic disease dietary intake. This cross-sectional study used meal biomarker data NHANES 2005–2010. Information on weekly was collected via questionnaire during household interview. The metabolic examined included mass index (BMI), serum cholesterol (total, high-density lipoprotein (HDL) low-density (LDL)), triglycerides, glycohemoglobin fasting glucose (n=8314, age⩾20, National Health Nutrition Examination Surveys (NHANES) 2007–2010). Biomarkers concentrations vitamins A, D, E, C, B-6, B-12, folate carotenoids (n=4162; 2005–2006). Multiple linear logistic regression methods adjusted for complex survey methodology covariates. American adults reported a mean 3.9 (95% confidence interval 3.7, 4.0) 1.8 (1.6, 1.9) meals/week. Over 50% ⩾3 >35% ⩾2 BMI more frequent or reporters (Ptrend⩽0.0004). Serum total, LDL HDL-cholesterol were related inversely (P<0.05). Frequencies also (P=0.0001). all micronutrients (except vitamin A lycopene) declined increasing (P<0.05); women ⩾50-year olds at risk. Reporters had lower HDL-cholesterol; however, profiles other did not indicate However, nutrients mostly plant foods sources frequency.
