Lifestyle, food consumption and nutrient intake patterns from a randomly selected group of 390 secondary pupils aged between 12-18 were evaluated. Demographic information and anthropometric measurements included weight, height, and skinfold thickness were taken. Nutrient intake was assessed using the 7-day dietary history method, using a photographic atlas as an aid. Mean energy intakes for boys and girls aged 12-15 and 15-18 were 11.3MJ and 14MJ and 9.1MJ and 8.9MJ respectively. As percentage energy, protein fat and carbohydrate intakes varied little between the different age-sex groupings and were approximately 13.7-14.5, 35.4-37 and 46.8-50 per cent respectively. For boys micronutrient intake for iron and folate achieving only 83 and 78 per cent and 98 and 90 per cent of the recommended nutrient intake (R.N.I.) for ages 12-15 and 15-18 respectively. Mean dietary fibre intakes were approximately 19.6-25g/day for boys aged 12-18 and 17g/day for girls of a similar age. The main sources of energy were bread, meat and meat products, potatoes/chips, confectionery and preserves. Fruit and vegetable consumption was low for all groups. The majority of those surveyed consumed the traditional main meals. Snacking was also common practice. The snack foods consumed were generally of a high fat/high sugar content. 1.1 per cent boys and 2.6 per cent of girls aged 12-15 and 5.5 per cent and 8.2 per cent of boys and girls aged 15-18 respectively had a BMI greater than 26 indicating a risk of overweight. Greater than 68 per cent of girls and 79.5 per cent of boys surveyed participated in some form of sport. Boys were more physically active than girls and older girls less active than younger. In conclusion, changes from present day practices would be beneficial to reduce incidence of chronic disease for present day teenagers.
对随机抽取的390名年龄在12至18岁之间的中学生的生活方式、食物消费和营养摄入模式进行了评估。收集了人口统计学信息和人体测量数据,包括体重、身高和皮褶厚度。采用7天饮食史法,并借助一本摄影图谱来评估营养摄入情况。12至15岁以及15至18岁男孩和女孩的平均能量摄入量分别为11.3兆焦耳和14兆焦耳以及9.1兆焦耳和8.9兆焦耳。作为能量百分比,不同年龄-性别分组之间蛋白质、脂肪和碳水化合物的摄入量差异不大,分别约为13.7 - 14.5%、35.4 - 37%和46.8 - 50%。对于男孩,12至15岁以及15至18岁时铁和叶酸的微量营养素摄入量分别仅达到推荐营养素摄入量(R.N.I.)的83%和78%以及98%和90%。12至18岁男孩的平均膳食纤维摄入量约为19.6 - 25克/天,同龄女孩为17克/天。能量的主要来源是面包、肉类及肉制品、土豆/薯片、糖果和蜜饯。所有组的水果和蔬菜消费量都很低。大多数接受调查的人都食用传统的主餐。吃零食也是常见的做法。所食用的零食通常脂肪/糖分含量高。12至15岁的男孩中有1.1%、女孩中有2.6%,15至18岁的男孩中有5.5%、女孩中有8.2%的体重指数(BMI)大于26,表明有超重风险。超过68%的受访女孩和79.5%的受访男孩参加了某种形式的体育运动。男孩比女孩身体活动更频繁,年龄较大的女孩比年龄较小的女孩活动更少。总之,改变当今的生活方式习惯将有助于降低当代青少年慢性病的发病率。
