A comparison of the results of surveys conducted in 1971 and 1977 involving secondary school students in Hobart has been made. It revealed an increasing intake of alcohol and vitamins but a decrease in analgesic usage in both sexes. Female students were smoking more frequently and more heavily and more of them were on weight-reducing diets. These results indicate that the kinds of health education in use at present are not effective.
对1971年和1977年在霍巴特对中学生进行的调查结果进行了比较。结果显示，男女生饮酒量和维生素摄入量增加，但镇痛药使用量减少。女生吸烟更频繁、量更大，而且更多女生在节食减肥。这些结果表明，目前所采用的健康教育方式并不有效。
