To examine intakes and variety of fruit and vegetables consumed by Australian young adults, also assessing differences by meal occasion and sociodemographic characteristics.
Secondary analysis of cross-sectional 24 h recall data collected through the 2011-12 National Nutrition and Physical Activity Survey. Crude means and proportions consuming fruits and vegetables were calculated. Pearson χ 2 tests, Kruskal-Wallis analyses and linear regression models were used to assess differences in mean intakes by age, BMI and sociodemographic variables. The variety eaten was determined based on the number of fruit and vegetable subgroups consumed.
Representative sample of metropolitan and rural areas across Australia.
Respondents aged 18-34 years were included (n 2397).
Mean daily intake of fruit (128 g/0·9 servings) and vegetables (205 g/2·7 servings) was lower than the minimum recommended intake set at 2 and 5 servings, respectively. Age was positively associated with fruit and vegetable intake (P=0·002, P<0·001), with 18-24-year-olds reporting the poorest vegetable variety compared with 25-29- and 30-34-year-olds (P=0·002). When controlling for total energy, males consumed less vegetables than females (P=0·002). A large proportion of the 15 % of respondents who consumed adequate amounts of fruits and vegetables on the day prior to the survey reported intake across all meal occasions (P<0·001).
Fruit and vegetable intake is suboptimal among Australian young adults. An age-appropriate campaign is recommended to target increased consumption, particularly for those aged 18-24 years, with opportunity to promote increased variety and consumption across the day.
调查澳大利亚年轻成年人水果和蔬菜的摄入量和种类,同时评估不同进餐时间和社会人口统计学特征的差异。
对 2011-12 年全国营养和身体活动调查中通过 24 小时回顾性数据收集的横断面数据进行二次分析。计算水果和蔬菜的粗均值和摄入量比例。采用 Pearson χ 2 检验、Kruskal-Wallis 分析和线性回归模型评估年龄、BMI 和社会人口统计学变量对平均摄入量的差异。根据食用的水果和蔬菜亚组数量确定食用的品种。
澳大利亚城乡代表性样本。
纳入年龄在 18-34 岁的受访者(n 2397)。
水果(128 g/0·9 份)和蔬菜(205 g/2·7 份)的日均摄入量均低于推荐的最低摄入量,分别为 2 份和 5 份。年龄与水果和蔬菜摄入量呈正相关(P=0·002,P<0·001),18-24 岁人群蔬菜品种最差,与 25-29 岁和 30-34 岁人群相比(P=0·002)。在控制总能量的情况下,男性蔬菜摄入量低于女性(P=0·002)。在调查前一天摄入足够水果和蔬菜的 15 %受访者中,很大一部分人报告称在所有进餐时间都有摄入(P<0·001)。
澳大利亚年轻成年人水果和蔬菜的摄入量不足。建议开展适合年龄的宣传活动,以增加摄入量,特别是针对 18-24 岁人群,同时有机会促进全天增加品种和摄入量。
