1974年对密云、昌平两县农村中小学生6,965人进行发育调查,看出:①一般发育规律与国内外调查结果相符;②与1959年比较,各项发育指标均有显著提高;③与1973年城市资料比较,身高、体重方面农村仍存在较大差距(胸围方面则农村有高于城市趋势);但与1959年资料比较,则各个发育指标的城乡差异都有大幅度的缩小。这是我国社会制度优越,毛主席革命路线正确,农村人民生活健康水平显著提高的具体体现。
In 1974, 6,965 rural primary and middle school students in two counties of Miyun and Changping were surveyed for development. The results showed that: ① The general rule of development was consistent with the findings at home and abroad; ②Compared with 1959, There is still a long way to go in terms of height and weight in rural areas (urban areas have a higher tendency than urban areas in terms of height and weight). However, compared with the data in 1959, the differences between urban and rural areas of various development indexes have greatly narrowed. This is a concrete manifestation of the remarkable social system in our country, the correct revolutionary line of Chairman Mao and the remarkable improvement of the living standards of the rural people.
