To investigate changes in intakes of 'negative' and 'positive' foods, fruit, vegetables, and salad in serial cohorts of 9-10-year-old children from 2000-2001 to 2010-2011.
For this serial, cross-sectional study, children in school year 5 (9-10 years of age) completed the SportsLinx Lifestyles Survey [n = 30,239 (15,336 boys and 14,903 girls)]. Changes in positive and negative food scores, and the proportion of boys and girls reportedly consuming fruit, vegetables and salad on the previous day to surveying, were investigated annually from 2000 to 2011.
The consumption of negative foods declined and positive foods increased significantly compared to baseline. Positive changes in fruit, vegetables and salad consumption were observed over time, with the most recent cohort more likely to consume fruit, vegetables and salad compared to the 2000-2001 baseline. Girls displayed more favourable positive and negative food scores and were more likely to consume fruit, salad and vegetables across several study years compared to boys.
The consumption of negative and positive foods, fruit, vegetables, and salad has improved over the last 10 years. In addition, girls appear to have better positive and negative food scores, and were more likely to consume fruit, vegetables and salad, across a number of study years or cohorts compared to boys. These encouraging findings suggest that children's food intake has improved since 2000. Furthermore, the data indicate that boys and girls may require separate or different healthy eating messages to further improve food intake.
调查2000 - 2001年至2010 - 2011年期间9至10岁儿童连续队列中“负面”和“正面”食物、水果、蔬菜及沙拉摄入量的变化。
在这项连续性横断面研究中，五年级（9至10岁）的儿童完成了SportsLinx生活方式调查[n = 30239（15336名男孩和14903名女孩）]。从2000年至2011年，每年调查正面和负面食物得分的变化，以及据报告在前一天调查前食用水果、蔬菜和沙拉的男孩和女孩的比例。
与基线相比，负面食物的消费量下降，正面食物的消费量显著增加。随着时间的推移，观察到水果、蔬菜和沙拉的消费量有积极变化，与2000 - 2001年基线相比，最近的队列更有可能食用水果、蔬菜和沙拉。在几个研究年份中，女孩的正面和负面食物得分更优，并且比男孩更有可能食用水果、沙拉和蔬菜。
在过去10年中，负面和正面食物、水果、蔬菜及沙拉的消费量有所改善。此外，与男孩相比，在多个研究年份或队列中，女孩似乎有更好的正面和负面食物得分，并且更有可能食用水果、蔬菜和沙拉。这些令人鼓舞的发现表明，自2000年以来儿童的食物摄入量有所改善。此外，数据表明，男孩和女孩可能需要不同的健康饮食信息来进一步改善食物摄入量。
