The location and time of snack consumption may influence the composition, nutrient content and portion sizes of snacks. In this study, we aimed to determine and compare the time, location and frequency of snack consumption among different age groups of Canadians.
Nationally representative dietary data from the 2015 Canadian Community Health Survey (CCHS) were used (19,677 participants aged ≥2 years). Dietary data were obtained using 24-h dietary recalls. Participants were categorized according to the frequency of snack consumption (1 time, 2-3 times, ≥4 times). The snack consumption over 24 h was divided into four time periods: before 10 am, 10 am to 3 pm, 3 pm to 8 pm and 8 pm to 12 am. Meal and snack location was categorized as at home; someone else's home; restaurants; and other.
Snacking 2-3 times per day was the most common reported frequency (53.0%). Snacking at home (73.0%) was more prevalent than snacking away from home (27.0%). The most frequently reported time for snacking among Canadians was 3 pm to 8 pm (36.3%), and the least frequently reported time was before 10 am (8.1%). Snacking contributed to a high proportion of Milk and Alternatives (23.7%) and Vegetables and Fruit (23.4%) food groups and lesser proportions of Grain Products (15.4%) and Meat & Alternatives (9.4%) food groups among Canadians.
Home is the main location, 3 pm to 8 pm is the main time, and 2-3 times per day is the most common reported frequency for snacking. A full understanding of snacking behaviors is needed in order to develop targeted strategies to improve the quality of snack food choices.
零食的摄入地点和时间可能会影响零食的组成、营养成分和份量。在这项研究中,我们旨在确定和比较不同年龄段加拿大人的零食摄入时间、地点和频率。
使用 2015 年加拿大社区健康调查(CCHS)的全国代表性饮食数据(19677 名年龄≥2 岁的参与者)。饮食数据通过 24 小时膳食回忆法获得。参与者根据零食的消费频率(1 次、2-3 次、≥4 次)进行分类。24 小时内的零食摄入量分为四个时间段:上午 10 点前、上午 10 点至下午 3 点、下午 3 点至晚上 8 点和晚上 8 点至午夜 12 点。餐点和零食的地点分为在家、在他人家中、在餐馆和其他地点。
每天吃 2-3 次零食是最常见的报告频率(53.0%)。在家吃零食(73.0%)比在外面吃零食(27.0%)更为普遍。加拿大人最常报告的吃零食时间是下午 3 点至 8 点(36.3%),最不常报告的时间是上午 10 点之前(8.1%)。零食摄入在很大程度上贡献了奶类和替代品(23.7%)和蔬菜与水果(23.4%)食物组,而谷物制品(15.4%)和肉及替代品(9.4%)食物组的摄入量则较少。
家是主要地点,下午 3 点至 8 点是主要时间,每天吃 2-3 次是最常见的报告频率。为了制定有针对性的策略来改善零食食品选择的质量,需要全面了解零食行为。
