In 1989 the National Food Administration in Sweden introduced a food-marking symbol called the 'Green Keyhole'. The aim of the campaign is to help consumers make lowfat, high-fibre food choices.
To describe the knowledge of the Green Keyhole symbol in a general female population, and to examine whether knowledge is associated with reported intake of dietary fat and fibre.
616 randomly selected women were examined and interviewed.
Intakes of dietary fat and fibre were analysed in relation to knowledge of the Green Keyhole symbol. Knowledge was assessed by means of an open-ended question.
62% of the women adequately understood the meaning of the Green Keyhole. These women were significantly younger (P < 0.0001). Mean body mass index (kg/m2+/-s.e.m.) was significantly higher among the women with more knowledge of the Green Keyhole symbol than those with less knowledge: 26.4 +/- 0.2 vs 25.6 +/- 0.2, (P = 0.002). There were no major differences in total fat intake or total fibre intake between the women with less and more knowledge. However the ratios of polyunsaturated fatty acids to saturated fatty acids and fibre intake per 4200 kJ (1000 kcal) were higher (P = 0.05 and P = 0.03, respectively) and intake of saturated fatty acids was lower (P = 0.05) in the diet among women with better knowledge.
The female population described here understands the campaign but their dietary behaviours do not appear to conform to the low-fat message.
1989年，瑞典国家食品管理局推出了一个名为“绿色钥匙孔”的食品标识。该活动的目的是帮助消费者选择低脂、高纤维的食品。
描述普通女性群体对“绿色钥匙孔”标识的了解情况，并研究这种了解是否与报告的膳食脂肪和纤维摄入量相关。
对616名随机选择的女性进行了检查和访谈。
分析膳食脂肪和纤维摄入量与对“绿色钥匙孔”标识的了解情况之间的关系。通过一个开放式问题评估了解程度。
62%的女性充分理解了“绿色钥匙孔”的含义。这些女性明显更年轻（P<0.0001）。对“绿色钥匙孔”标识了解较多的女性的平均体重指数（kg/m²±标准误）显著高于了解较少的女性：26.4±0.2 vs 25.6±0.2，（P=0.002）。了解较少和较多的女性在总脂肪摄入量或总纤维摄入量上没有重大差异。然而，了解较多的女性饮食中多不饱和脂肪酸与饱和脂肪酸的比例以及每4200千焦（1000千卡）的纤维摄入量更高（分别为P=0.05和P=0.03），饱和脂肪酸的摄入量更低（P=0.05）。
这里描述的女性群体理解该活动，但她们的饮食行为似乎不符合低脂信息。
