Previous studies in Australian children/adolescents and adults examining added sugar (AS) intake were based on now out-of-date national surveys. We aimed to examine the AS and free sugar (FS) intakes and the main food sources of AS among Australians, using plausible dietary data collected by a multiple-pass, 24-h recall, from the 2011-12 Australian Health Survey respondents (n 8202). AS and FS intakes were estimated using a previously published method, and as defined by the WHO, respectively. Food groups contributing to the AS intake were described and compared by age group and sex by one-way ANOVA. Linear regression was used to test for trends across age groups. Usual intake of FS (as percentage energy (%EFS)) was computed using a published method and compared with the WHO cut-off of <10%EFS. The mean AS intake of the participants was 60·3 (SD 52·6) g/d. Sugar-sweetened beverages accounted for the greatest proportion of the AS intake of the Australian population (21·4 (sd 30·1)%), followed by sugar and sweet spreads (16·3 (SD 24·5)%) and cakes, biscuits, pastries and batter-based products (15·7 (sd 24·4)%). More than half of the study population exceeded the WHO's cut-off for FS, especially children and adolescents. Overall, 80-90% of the daily AS intake came from high-sugar energy-dense and/or nutrient-poor foods. To conclude, the majority of Australian adults and children exceed the WHO recommendation for FS intake. Efforts to reduce AS intake should focus on energy-dense and/or nutrient-poor foods.
以往针对澳大利亚儿童/青少年及成年人添加糖(AS)摄入量的研究是基于现已过时的全国性调查。我们旨在利用通过多次24小时回顾法收集的可靠饮食数据,对澳大利亚人AS和游离糖(FS)的摄入量以及AS的主要食物来源进行研究,这些数据来自2011 - 12年澳大利亚健康调查的受访者(n = 8202)。AS和FS摄入量分别采用先前发表的方法并根据世界卫生组织的定义进行估算。通过单因素方差分析按年龄组和性别描述并比较了对AS摄入量有贡献的食物类别。使用线性回归检验各年龄组之间的趋势。采用已发表的方法计算FS的通常摄入量(以能量百分比(%EFS)表示),并与世界卫生组织<10%EFS的临界值进行比较。参与者的平均AS摄入量为60·3(标准差52·6)克/天。含糖饮料在澳大利亚人群AS摄入量中占比最大(21·4(标准差30·1)%),其次是糖和甜味酱料(16·3(标准差24·5)%)以及蛋糕、饼干、糕点和面糊类产品(15·7(标准差24·4)%)。超过一半的研究人群超过了世界卫生组织对FS的临界值,尤其是儿童和青少年。总体而言,每日AS摄入量的80 - 90%来自高糖、能量密集型和/或营养匮乏的食物。总之,大多数澳大利亚成年人和儿童超过了世界卫生组织对FS摄入量的建议。减少AS摄入量的努力应集中在能量密集型和/或营养匮乏的食物上。
