The release of the Canadian Community Health Survey (CCHS), Nutrition 2015 provides a unique opportunity since CCHS 2004 to investigate food choices of Canadian children and adolescents at a national level.
This study examined the quality and quantity of food choices of children ages 2-8 years and adolescents 9-18 years, using Health Canada's Surveillance Tool Tier System 2014. It is hypothesized that Canadian children and adolescents are consuming diets poor in nutritional quality based on evidence from the last national nutrition survey in 2004.
Intakes from CCHS 2015, 24-h dietary recall were categorized into Health Canada's Tiers 1-4, based on CNF/CFG classification system and thresholds for nutrients to limit i.e., total fat, saturated fats, sugars, and sodium to assess quality of food choices. Additionally, dietary intakes were grouped according to Canada's 2007 food guide servings as the 2019 food guide was not available.
Majority of foods reported by children 2-18 years were categorized as Tier 2 and Tier 3 foods. Investigation of energy contributions from the Tier 4 and "other foods" represented 21-25% of daily calorie intake and of these foods, high fat and/or high sugar foods contributed majority of daily calories to these categories.
This study showed Canadian children 2-18 years are consuming diets high in nutrients recommended to limit. Evidence from this study provides a unique opportunity to improve the nutritional quality of foods, and the food choices of children.
《加拿大社区健康调查(CCHS),2015年营养调查》的发布提供了一个自2004年CCHS以来在全国范围内调查加拿大儿童和青少年食物选择的独特机会。
本研究使用加拿大卫生部2014年监测工具层级系统,调查了2至8岁儿童和9至18岁青少年食物选择的质量和数量。基于2004年上次全国营养调查的证据,推测加拿大儿童和青少年的饮食营养质量较差。
根据加拿大国家营养文件/加拿大食品指南(CNF/CFG)分类系统以及营养素限制阈值(即总脂肪、饱和脂肪、糖和钠),将2015年CCHS的24小时饮食回忆摄入量分为加拿大卫生部的第1 - 4层,以评估食物选择的质量。此外,由于没有2019年的食物指南,饮食摄入量按照加拿大2007年食物指南的份数进行分组。
2至18岁儿童报告的大多数食物被归类为第2层和第3层食物。对第4层和“其他食物”的能量贡献调查显示,它们占每日卡路里摄入量的21 - 25%,在这些食物中,高脂肪和/或高糖食物占这些类别每日卡路里的大部分。
本研究表明,2至18岁的加拿大儿童所食用的饮食中,建议限制的营养素含量较高。本研究的证据为改善食物的营养质量和儿童的食物选择提供了一个独特的机会。
