目的：本研究探讨了报告的食物和营养素的摄入量，饮食暴露和心血管疾病的生物标志物的历史，试图减肥。方法：饮食，人体测量和生化数据来自第三次全国健康与营养调查（1988-1994年），n= 13 092。尝试减肥的历史变量创建如下：当前尝试减肥，过去12个月尝试过（Y/Y）;当前尝试减肥，但过去12个月未尝试（Y/N）;当前未尝试减肥，但过去12个月尝试过（N/Y）;现在未尝试减肥，过去12个月未尝试（N/N）。采用多元回归分析方法来检验尝试减肥的历史与报告的能量、营养素、低营养密度食物能量百分比的摄入量之间的独立关联（甜味剂、烘焙和乳制品甜点、可见脂肪和咸味零食），以及维生素、类胡萝卜素和脂质的血清浓度。Y/Y组的男性和女性报告的能量摄入量低于N/N组（P< 0.0000）。然而，Y/Y组报告的来自脂肪和碳水化合物的能量百分比与N/N组没有差异。Y/Y组的男性从低营养密度食物中获得的能量百分比较低，但女性则不然。报告叶酸、维生素A、B 6、B 12、C、E和铁的估计平均需求量（AUC）以及钙的充足摄入量（AI）的相对几率不受男性尝试减肥史的不利影响。在女性中，Y/Y组满足叶酸和维生素E的几率较低。一些历史的减肥类别显着的积极预测血清维生素和类胡萝卜素浓度，或无关的心血管疾病风险biomarkers.Conclusions：有很少的证据表明，在那些报告重复尝试减肥的营养风险增加。
Objective: This study examined the reported intake of foods and nutrients, and biomarkers of dietary exposure and cardiovascular disease in relation to history of trying to lose weight.Methods: Dietary, anthropometric and biochemical data were from the third National Health and Nutrition Examination Survey (1988–1994), n= 13 092. The history of attempting weight loss variable was created as follows: trying to lose currently and tried in the past 12 months (Y/Y); trying to lose currently, but not tried in the past 12 months (Y/N), not trying currently, but tried in the past 12 months (N/Y); not trying now and not tried in the past 12 months (N/N). Multiple regression methods were used to examine the independent association of history of trying to lose weight with reported intakes of energy, nutrients, percentage energy from low-nutrient-dense foods (sweeteners, baked and dairy desserts, visible fats and salty snacks), and serum concentrations of vitamins, carotenoids and lipids.Results: Men and women in the Y/Y group reported lower energy intake relative to the N/N group (P< 0.0000). However, the reported percentage energy from fat and carbohydrate by the Y/Y group did not differ from the N/N group. Percentage of energy from low-nutrient-dense foods was lower in men in the Y/Y group but not women. The relative odds of reporting the estimated average requirement (EAR) of folate, and vitamins A, B 6, B 12, C, E and iron and adequate intake (AI) of calcium were not adversely affected by history of trying to lose weight in men. In women, the odds of meeting the folate and vitamin E EAR were lower in the Y/Y group. Some history of weight loss categories were significant positive predictors of serum vitamin and carotenoid concentrations, or unrelated to cardiovascular disease risk biomarkers.Conclusions: There was little evidence for increased nutritional risk in those reporting repeat attempts at weight loss.
