Eating a diet high in fruits and vegetables as part of an overall healthful diet can help lower chronic disease risk and aid in weight management. Increasing the percentage of Americans who consume enough fruits and vegetables every day is part of the Healthy People 2010 objectives for the nation. Assessing trends in consumption of these foods is important for tracking public health initiatives to meet this goal and for planning future objectives.
We assessed total and sex-specific changes in daily consumption of fruits and vegetables among 1,227,969 adults in the 50 U.S. states and the District of Columbia who participated in the Behavioral Risk Factor Surveillance System from 1994 through 2005. To estimate changes in consumption according to dietary recommendations that were in place during the years examined, we used geometric mean and the percentage of people eating fruits or vegetables or both five or more times per day. Estimates were standardized for sex, age, and race/ethnicity and analyzed by multivariate regression.
From 1994 through 2005, the geometric mean frequency of consumption of fruits and vegetables declined slightly (standardized change: men and women, -0.22 times/day; men, -0.26 times/day; women, -0.17 times/day). The proportion of men and women eating fruits or vegetables or both five or more times per day was virtually unchanged (men, 20.6% vs 20.3%; women, 28.4% vs 29.6%); however, we found small increases for men aged 18 to 24 years and for women who were aged 25 to 34 years, non-Hispanic black, or nonsmokers. Consumption of fruit juice and non-fried potatoes declined for both sexes.
The frequency of fruit and vegetable consumption changed little from 1994 through 2005. If consumption is to be increased, we must identify and disseminate promising individual and environmental strategies, including policy change.
作为整体健康饮食的一部分,食用富含水果和蔬菜的饮食有助于降低慢性病风险并有助于体重管理。提高每天摄入足够水果和蔬菜的美国人的比例是《2010年美国人健康目标》的一部分。评估这些食物的消费趋势对于跟踪实现这一目标的公共卫生举措以及规划未来目标非常重要。
我们评估了1994年至2005年期间参与行为危险因素监测系统的美国50个州和哥伦比亚特区的1,227,969名成年人中水果和蔬菜每日消费的总体及按性别划分的变化。为了根据所研究年份的饮食建议估计消费变化,我们使用几何平均数以及每天食用水果或蔬菜或两者达五次或更多次的人群百分比。估计值按性别、年龄和种族/族裔进行了标准化,并通过多变量回归进行分析。
从1994年到2005年,水果和蔬菜消费的几何平均频率略有下降(标准化变化:男性和女性,-0.22次/天;男性,-0.26次/天;女性,-0.17次/天)。每天食用水果或蔬菜或两者达五次或更多次的男性和女性比例基本未变(男性,20.6%对20.3%;女性,28.4%对29.6%);然而,我们发现18至24岁的男性以及25至34岁、非西班牙裔黑人或不吸烟的女性有小幅增加。男女的果汁和非油炸土豆消费量均下降。
从1994年到2005年,水果和蔬菜的消费频率变化不大。如果要增加消费量,我们必须确定并传播有前景的个人和环境策略,包括政策变革。
