目的分析中国部分城市1998-2008年儿童食物喜好及食物购买的变化,为国家有关部门制定相关干预策略提供理论依据。方法利用1998年和2008年在广州等城市开展的儿童饮食行为现况调查的数据进行分析。2次调查均采用三阶段分层整群随机抽样方法,共选取8～14岁儿童6 189名作为研究对象,使用问卷调查的方法收集其对食物的喜好特点及食物购买的信息。结果儿童有特别喜欢吃某种食物的比例从1998年的78.9%下降到2008年的69.6%,有特别不喜欢吃某种食物的比例从65.5%下降到51.7%。喜好水果类的比例下降了11.3%,喜欢零食(不包括饮料)类的比例上升了9.9%。仍有40.0%的儿童特别不喜欢吃蔬菜。10 a间总是与家人一起购买食物的比例基本不变,而从不与家人一起购买食物的比例从2.4%上升到4.1%。结论城市儿童中仍存在不合理的食物喜好倾向,参与食物购买的情况10 a间变化不大。仍需加强儿童及其看护人的健康教育,从小培养健康的饮食行为。 Objective To analyze the changes of children’s food preferences and food purchases from 1998 to 2008 in some Chinese cities to provide theoretical basis for the relevant state departments to make relevant intervention strategies. Methods The data from a survey of children’s eating behaviors conducted in Guangzhou and other cities in 1998 and 2008 were analyzed. In the two surveys, stratified cluster random sampling was conducted in three stages. A total of 6,188 children aged 8-14 years were selected as research subjects. The questionnaires were used to collect their preferences for foods and food purchase information. As a result, the percentage of children who had a particular preference for eating certain foods dropped from 78.9% in 1998 to 69.6% in 2008, and the proportion who did not particularly like to eat certain foods dropped from 65.5% to 51.7%. The proportion of like fruits decreased by 11.3%, and the proportion of those who like snacks (excluding drinks) increased by 9.9%. 40.0% still do not like to eat vegetables. The proportion of people who always bought food with their families during the 10-year period remained basically unchanged while the proportion that never bought food with their families rose from 2.4% to 4.1%. Conclusions There is still an unreasonable tendency of food preference among urban children, and the changes in food purchase have not changed much in 10 years. Health education for children and their caregivers still needs to be strengthened, and healthy eating behaviors should be cultivated from childhood.
