To examine overall usual fruit and vegetable (FV) intake and preferences among grade 5-8 students participating in the Northern Fruit and Vegetable Program (NFVP) over 3 years (2014-2016). In each year, a survey was administered 4 months into the NFVP in Northern Ontario, Canada. A total of 4744 students participated (2014 = 1551; 2015 = 1617; 2016 = 1576). Overall usual FV intake did not change over the 3 years, yet preferences generally increased. FVs offered by the NFVP were rated higher on preference than those not offered (fruit < 0.001; vegetables < 0.005). In each year, participants were more likely to consume a higher overall usual fruit intake if they had higher preference for fruit as offered by the NFVP (all < 0.05) as opposed to not offered by the NFVP (all > 0.05). For vegetables, participants were more likely to consume higher overall usual vegetables if they had a higher preference for vegetables as offered (all < 0.05) and not offered by the NFVP (all < 0.05). This study documented that higher preferences for fruit (as offered) and vegetables (as offered and not offered) were associated with higher overall usual FV intakes within each of the 3 years.
为研究参与北方果蔬项目（NFVP）三年（2014 - 2016年）的5至8年级学生的总体日常果蔬摄入量及偏好情况。每年，在加拿大安大略省北部的NFVP项目开展4个月后进行一次调查。共有4744名学生参与（2014年 = 1551名；2015年 = 1617名；2016年 = 1576名）。总体日常果蔬摄入量在这三年间没有变化，但偏好普遍有所增加。NFVP提供的果蔬在偏好评分上高于未提供的果蔬（水果 < 0.001；蔬菜 < 0.005）。每年，如果参与者对NFVP提供的水果有更高偏好（均 < 0.05），而非NFVP未提供的水果（均 > 0.05），那么他们更有可能摄入更高的总体日常水果量。对于蔬菜而言，如果参与者对提供的蔬菜（均 < 0.05）和未提供的蔬菜（均 < 0.05）有更高偏好，他们更有可能摄入更高的总体日常蔬菜量。本研究表明，在这三年中的每一年，对水果（提供的）和蔬菜（提供的及未提供的）的更高偏好都与更高的总体日常果蔬摄入量相关。
