Childhood obesity is an increasing problem in a transitional society such as Thailand. To study physical growth and puberty in obese children, a cross-sectional survey of growth and age at menarche was carried out in schoolgirls aged between 8 and 16 years old. The 3,120 girls were divided into two groups based on weight-for-height criteria. Girls with weight-for-height between 80 and 120% were classified as normal stature (2,625; 84.1%) and those more than 120% were obese (495; 15.9%). Using probit analysis, age at menarche in obese girls was 0.9 year earlier than normal stature girls (11.5 years vs 12.4 years). At age 12, obese girls were reaching menarche 2.8 times more when compared with the normal stature girls. In terms of growth pattern, obese girls were taller and grew faster during the prepubertal period, and then reached their final height earlier than the normal stature girls (13 years vs 15 years). The final height in obese girls was significantly shorter (153.0 cm and 155.0 cm, p = 0.01). We conclude that: 1) obese girls grow faster, have earlier menarche and then stop growing earlier, and 2) obese girls tend to be shorter as adults, compared with normal stature girls.
在泰国这样的转型社会中，儿童肥胖问题日益严重。为了研究肥胖儿童的身体发育和青春期情况，对8至16岁的女学生进行了一项关于初潮时生长和年龄的横断面调查。3120名女孩根据身高体重标准分为两组。身高体重在80%至120%之间的女孩被归类为正常身材（2625名；84.1%），超过120%的女孩为肥胖（495名；15.9%）。使用概率分析，肥胖女孩的初潮年龄比正常身材女孩早0.9岁（11.5岁对12.4岁）。在12岁时，肥胖女孩初潮的发生率是正常身材女孩的2.8倍。在生长模式方面，肥胖女孩在青春期前更高且生长更快，然后比正常身材女孩更早达到最终身高（13岁对15岁）。肥胖女孩的最终身高明显更矮（153.0厘米和155.0厘米，p = 0.01）。我们得出以下结论：1）肥胖女孩生长更快，初潮更早，然后更早停止生长；2）与正常身材女孩相比，肥胖女孩成年后往往更矮。
