The amount of sugars consumed by young adolescents was assessed in 1990 using the same methods as those employed in a similar survey in 1980. The children were the same age (mean 11 years 6 months) and from the same seven schools in both survey. In 1980, 405 children completed the study and 379 in 1990. Information was collected using two 3-day dietary diaries, each child being interviewed by a dietitian upon completion of a diary. The dietitian in this study was calibrated closely with the dietitian who undertook the 1980 study so as to ensure comparable diet evaluation methods. Total sugars consumption was unchanged (117 g/day in 1980, 118 g/day in 1990) but consumption of non-milk extrinsic sugars increased (83 g/day in 1980, 90 g/day in 1990) and milk and intrinsic sugars decreased (34 g/day in 1980, 28 g/day in 1990) between the two surveys. In 1990, non-milk extrinsic sugars contributed 17% to total dietary energy intake, while milk and intrinsic sugars contributed 5%. There was little difference in percent contributions between the sexes, but some social-class trends were apparent. Confectionery provided 33% and soft drinks provided 27% of non-milk extrinsic sugars, these two dietary sources providing 60% of non-milk extrinsic or 46% of total sugars intake. These levels of consumption are considerably higher than those currently recommended in the UK.
1990年，采用与1980年类似调查相同的方法，对青少年的糖分摄入量进行了评估。两次调查中的儿童年龄相同（平均11岁6个月），且来自相同的七所学校。1980年有405名儿童完成了研究，1990年有379名。通过两份为期3天的饮食日记收集信息，每份日记完成后，由一名营养师对每个孩子进行访谈。本研究中的营养师与进行1980年研究的营养师进行了密切校准，以确保饮食评估方法具有可比性。两次调查之间，总糖摄入量没有变化（1980年为117克/天，1990年为118克/天），但非乳类外源性糖的摄入量增加了（1980年为83克/天，1990年为90克/天），而乳类和内源性糖的摄入量减少了（1980年为34克/天，1990年为28克/天）。1990年，非乳类外源性糖占膳食总能量摄入的17%，而乳类和内源性糖占5%。两性之间的贡献百分比差异不大，但存在一些社会阶层趋势。糖果提供了33%的非乳类外源性糖，软饮料提供了27%，这两种饮食来源提供了60%的非乳类外源性糖或46%的总糖摄入量。这些消费水平远高于英国目前建议的水平。
