This study investigated, in on-reserve First Nations (FN) youth in Ontario, Canada, the following: (a) the intakes of vegetable and fruit, "other" foods and relevant nutrients as compared to current recommendations and national averages, (b) current prevalence rates of overweight and obesity and (c) the relationship between latitude and dietary intakes. Twenty-four-hour diet recalls were collected via the Waterloo Web-Based Eating Behaviour Questionnaire (WEB-Q) (n = 443). Heights and weights of participants were self reported using measured values and Body Mass Index was categorized using the International Obesity Task Force cutoffs. Food group and nutrient intakes were compared to current standards, Southern Ontario Food Behaviour data and the Canadian Community Health Survey, Cycle 2.2, using descriptive statistics. Mean vegetable and fruit, fibre and folate intakes were less than current recommendations. Girls aged 14-18 years had mean intakes of vitamin A below current recommendations for this sub-group; for all sub-groups, mean intakes of vegetables and fruit were below Canadian averages. All sub-groups also had intakes of all nutrients and food groups investigated that were less than those observed in non-FN youth from Southern Ontario, with the exception of "other" foods in boys 12-18 years. Prevalence rates of overweight and obesity were 31.8% and 19.6%, respectively, exceeding rates in the general population. Dietary intakes did not vary consistently by latitude (n = 248), as revealed by ANOVA. This study provided a unique investigation of the dietary intakes of on-reserve FN youth in Ontario and revealed poor intakes of vegetables and fruit and related nutrients and high intakes of "other" foods. Prevalence rates of overweight and obesity exceed those of the general population.
本研究调查了加拿大安大略省保留地的第一民族(FN)青年:(a)与当前推荐量和全国平均水平相比,蔬菜和水果、“其他”食品和相关营养素的摄入量,(b)超重和肥胖的当前流行率,以及(c)纬度与饮食摄入量之间的关系。通过滑铁卢基于网络的饮食行为问卷(WEB-Q)(n = 443)收集 24 小时饮食回忆。参与者的身高和体重使用测量值自我报告,体重指数使用国际肥胖工作组的分类标准进行分类。使用描述性统计比较食物组和营养素摄入量与当前标准、安大略省南部的食品行为数据和加拿大社区健康调查(第二周期 2.2)。平均蔬菜和水果、纤维和叶酸摄入量低于当前建议量。14-18 岁女孩的维生素 A 摄入量低于该亚组的当前建议量;对于所有亚组,蔬菜和水果的平均摄入量均低于加拿大的平均值。所有亚组的所有营养素和食物组的摄入量也低于安大略省南部非第一民族青年的摄入量,除了 12-18 岁男孩的“其他”食物。超重和肥胖的流行率分别为 31.8%和 19.6%,高于一般人群的流行率。饮食摄入量并没有因纬度而始终变化(n = 248),这一点通过方差分析得到了揭示。本研究对安大略省保留地第一民族青年的饮食摄入量进行了独特的调查,结果显示蔬菜和水果以及相关营养素的摄入量较低,而“其他”食物的摄入量较高。超重和肥胖的流行率高于一般人群。
