项目摘要

DESCRIPTION (provided by applicant): Recent data from the 1999-2000 National Health and Nutrition Examination Survey indicate a continuation of the trend for increasing prevalence of obesity in the US population. These trends reflect a persistent positive energy balance in the US population. Ecologic data suggest that energy intakes in the past three decades have increased without a concomitant increase in energy expenditure. Multiple factors are probably responsible for the increase in energy intake, but are poorly understood. Bio-behavioral factors such as consumption of foods prepared away from home and large portion sizes are currently receiving attention as possible contributors to increasing energy intake. However, an expanding food supply, aggressive food marketing, and changes in work and leisure behaviors over the past three decades may be expected to influence several other food related behaviors that may relate to energy intake and thus affect energy balance. These food consumption behaviors include dietary variety and energy density; frequency of eating episodes/snacking; breakfast, and evening/night eating patterns. Surprisingly little, however, is known about trends in these food consumption behaviors. Therefore, the overall objective of the proposed study is to examine trends in patterns of food consumption (as reflected in dietary variety and energy density, frequency of eating episodes/snacking, breakfast, and evening/night eating behaviors) from 1971-2002, to understand their potential contribution to energy intake and increasing adiposity of the US population. Accordingly, we will test these hypotheses: 1) patterns of food consumption (dietary variety and energy density, frequency of eating episodes/snacking, and breakfast, evening/night eating behaviors) are independent predictors of self-reported dietary energy intake, indices of adiposity, and biomarkers in the adult US population, 2) the patterns of food consumption have changed from 1971 to 2002, and 3) the secular changes in patterns of food consumption from 1971-2002 are associated with secular changes in energy intake and indices of adiposity from 1971-2002. We will use nationally representative data from the National Health and Nutrition Examination Surveys I (1971-74), II (1976-1980), III (1988-1994), and 1999-2002, to examine these hypotheses. An examination of changing patterns of food consumption can help in understanding the correlates of increasing energy intake and permit designing and targeting of suitable interventions by both the public and the private sectors.
描述(由申请人提供):1999-2000年全国健康和营养检查调查的最新数据表明,美国人口中肥胖症患病率持续上升的趋势。这些趋势反映了美国人口持续的正能量平衡。生态学数据表明,在过去三十年中,能量摄入增加了,但能量消耗却没有随之增加。多种因素可能导致能量摄入的增加,但人们对这些因素知之甚少。生物行为因素,如食用离家准备的食物和大份量的食物,目前正在受到关注,因为它们可能是增加能量摄入的因素。然而,在过去三十年中,不断扩大的食物供应,积极的食品营销以及工作和休闲行为的变化可能会影响其他几种与食物相关的行为,这些行为可能与能量摄入有关,从而影响能量平衡。这些食物消费行为包括膳食种类和能量密度;进食/吃零食的频率;早餐,晚上/晚上的饮食模式。然而,令人惊讶的是,人们对这些食物消费行为的趋势知之甚少。因此,本研究的总体目标是研究1971-2002年间食物消费模式的趋势(反映在饮食种类和能量密度、进食频率/零食、早餐和晚上/晚上进食行为上),以了解它们对能量摄入和美国人口肥胖增加的潜在贡献。因此,我们将测试这些假设:1)食物消费模式(饮食种类和能量密度,进食/零食频率,早餐,晚上/晚上进食行为)是美国成年人自我报告的饮食能量摄入,肥胖指数和生物标志物的独立预测因子;2)1971年至2002年,食物消费模式发生了变化;(3) 1971-2002年食物消费模式的长期变化与1971-2002年能量摄入和肥胖指数的长期变化相关。我们将使用来自全国健康和营养检查调查I(1971-74)、II(1976-1980)、III(1988-1994)和1999-2002的具有全国代表性的数据来检验这些假设。对不断变化的食物消费模式进行检查,有助于了解增加能量摄入的相互关系,并允许公共和私营部门设计和确定适当干预措施的目标。
