We examined trends in fruit and vegetable consumption in the United States.
A 6-item food frequency questionnaire was used to assess consumption among 434 121 adults in 49 states and the District of Columbia who were sampled in random-digit-dialed telephone surveys administered in 1994, 1996, 1998, and 2000.
Although the geometric mean frequency of fruit and vegetable consumption declined slightly, the proportion of respondents consuming fruits and vegetables 5 or more times per day did not change. With the exception of the group aged 18 to 24 years, which experienced a 3-percentage-point increase, little change was seen among sociodemographic subgroups.
Frequency of fruit and vegetable consumption changed little from 1994 to 2000. If increases are to be achieved, additional efforts and new strategies will be needed.
我们研究了美国水果和蔬菜消费的趋势。
采用一份包含6个项目的食物频率问卷，对49个州和哥伦比亚特区的434121名成年人的消费情况进行评估，这些成年人是在1994年、1996年、1998年和2000年通过随机数字拨号电话调查抽取的样本。
尽管水果和蔬菜消费的几何平均频率略有下降，但每天食用水果和蔬菜5次或更多次的受访者比例没有变化。除18至24岁年龄组增加了3个百分点外，社会人口亚组中变化不大。
1994年至2000年期间，水果和蔬菜的消费频率变化不大。若要实现消费增长，将需要付出更多努力并采取新策略。
