Secular changes in height and weight measurements were examined in five- to 14-year-olds from 1973 to 1984. The age-sex specific 85th percentile was used to classify persons as overweight (based on ponderal index; kg/m3). Secular increases in weight (2.5 kg), and ponderosity (0.5-0.7 kg/m3) were found. Gains in ponderosity over the 11-year period were greater at the 75th percentile than at the 25th percentile, and the prevalence of overweight increased from 15 per cent to 24 per cent.
对1973年至1984年间5至14岁儿童的身高和体重测量的长期变化进行了研究。使用特定年龄和性别的第85百分位数将个体分类为超重(基于体重指数;千克/立方米)。发现体重有长期增加(2.5千克),体重指数也有增加(0.5 - 0.7千克/立方米)。在第75百分位数处,11年间体重指数的增加幅度大于第25百分位数处,超重患病率从15%上升至24%。
