Secular changes in height and weight of primary (6th year grade) and junior high (3rd year grade) school children in the city of Sendai during the period of 1973 to 1987 were analyzed in comparison with the counterpart changes in Miyagi prefecture and all Japan. The regression analysis revealed that there was a linear relationship between the year of examination and the measures of height and weight both in boys and girls of primary and junior high schools. The secular gain was very steady, but the annual gain was small, i.e., about one third to one sixth of the counterpart value in 1960-1964 when the secular gain was the largest. Such reduction in secular gain is apparently common throughout the country. Rohrer's and Quetlet's indices stayed essentially unchanged throughout the 15 year study period among the school children in Sendai, in Miyagi and in Japan.
对1973年至1987年期间仙台市小学六年级和初中三年级学生的身高和体重的长期变化进行了分析，并与宫城县和全日本的相应变化进行了比较。回归分析表明，在小学和初中的男女生中，检查年份与身高和体重测量值之间存在线性关系。长期增长非常稳定，但年增长幅度较小，即约为1960 - 1964年长期增长幅度最大时相应数值的三分之一至六分之一。这种长期增长幅度的下降在全国显然很普遍。在整个15年的研究期间，仙台市、宫城县和日本的在校儿童的罗勒指数和奎特利指数基本保持不变。
