To assess changes in food consumption and physical activity levels in schoolchildren.
A study was conducted with a representative sample (n = 4,168) of schoolchildren aged between seven and ten years living in the city of Florianópolis, Southern Brazil. Food consumption and physical activity were assessed in two school-based studies in 2002 (n = 2,936; 51% boys; mean age = 8.5 years) and 2007 (n = 1,232; 50.7% boys; mean age = 8.6 years), using illustrated questionnaires. The chi-square test was used to assess changes in the consumption of eight foods/food groups, in terms of the recommendations of the Brazilian Food Guidelines and physical activity levels (assessed according to tertiles of distribution of score and type of transportation to school). Analyses were performed according to the type of school attended (private or public).
There was a reduction in the proportion of schoolchildren who reported eating fruits, vegetables, beans, meat, snack foods, pizza, French fries and sodas. A higher proportion of private school children met the recommendations that restricted the consumption of sodas, pizza and French fries and promoted the consumption of fruits and vegetables, in both studies. On the other hand, a higher proportion of public school children met the recommendations of meat consumption in 2007. Median values of scores of physical activity decreased in 2007. In both years, private school children were more active. The proportion of schoolchildren who actively commuted to school decreased from 49% to 41% (p < 0.01).
There was a reduction in the consumption of markers of a healthy diet (beans, meat/fish, fruits and vegetables) and high-energy and low-nutrient foods (sodas, snack foods and pizza/French fries). In addition, there was a decrease in the proportion of schoolchildren who reported actively commuting to school.
评估学童的食物消费和身体活动水平的变化。
对巴西南部弗洛里亚诺波利斯市7至10岁的学童进行了一项代表性抽样研究（n = 4168）。在2002年（n = 2936；51%为男孩；平均年龄 = 8.5岁）和2007年（n = 1232；50.7%为男孩；平均年龄 = 8.6岁）的两项校内研究中，使用图文问卷对食物消费和身体活动进行了评估。根据巴西食物指南的建议以及身体活动水平（根据得分分布三分位数和上学交通方式进行评估），采用卡方检验来评估八种食物/食物组的消费变化。根据就读学校类型（私立或公立）进行分析。
报告食用水果、蔬菜、豆类、肉类、休闲食品、披萨、薯条和汽水的学童比例有所下降。在两项研究中，私立学校儿童中符合限制汽水、披萨和薯条消费并促进水果和蔬菜消费建议的比例更高。另一方面，2007年公立学校儿童中符合肉类消费建议的比例更高。2007年身体活动得分的中位数有所下降。在这两年中，私立学校儿童都更活跃。积极步行或骑车上学的学童比例从49%降至41%（p < 0.01）。
健康饮食标志（豆类、肉类/鱼类、水果和蔬菜）以及高能量和低营养食物（汽水、休闲食品和披萨/薯条）的消费量有所下降。此外，报告积极步行或骑车上学的学童比例也有所下降。
