Large population growth surveys of children and adolescents aged 6 to 18 y were undertaken in Hong Kong in 1963 and 1993. The global epidemic of obesity is a major public health concern. To monitor the impact of this epidemic in Hong Kong children and to identify secular changes in growth, a further growth survey was undertaken in 2005/6.
Cross-sectional height and weight measurements of 14,842 children and adolescents aged 6 to 18 y from Hong Kong's 18 districts were obtained during the 2005/6 school year. Percentile curves were constructed using LMS method and sex-specific percentile values of weight-for-age, height-for-age, and BMI-for-age were compared with those data from 1963 and 1993.
Secular changes in height, weight and BMI were noted between 1963 and 1993 and between 1993 and 2005/6. In the latter period, greater changes were observed at younger ages, and particularly in boys. On an annual basis, the 1993-2005/6 changes were less than those during 1963-1993. Using the International Obesity Task Force cut-offs, 16.7% of children were overweight or obese in 2005/6, which was a 5.1% increase since 1993.
These data provide policy-makers with further evidence of the secular changes in child growth and the increasing obesity epidemic among Hong Kong children.
1963年和1993年在香港对6至18岁的儿童和青少年进行了大规模的人口增长调查。肥胖的全球流行是一个主要的公共卫生问题。为了监测这一流行对香港儿童的影响并确定生长的长期变化,2005/6年进行了进一步的生长调查。
在2005/6学年期间,对来自香港18个区的14842名6至18岁的儿童和青少年进行了横断面身高和体重测量。使用LMS方法构建百分位数曲线,并将年龄别体重、年龄别身高和年龄别BMI的性别特异性百分位数与1963年和1993年的数据进行比较。
1963年至1993年以及1993年至2005/6年期间,身高、体重和BMI均出现了长期变化。在后一时期,较年轻年龄段的变化更大,尤其是男孩。按年度计算,1993 - 2005/6年的变化小于1963 - 1993年期间。根据国际肥胖特别工作组的临界值,2005/6年有16.7%的儿童超重或肥胖,自1993年以来增加了5.1%。
这些数据为政策制定者提供了进一步的证据,证明儿童生长的长期变化以及香港儿童肥胖流行情况的加剧。
