摘要背景：在泰国，对增长的研究可以追溯到 1975 年，但还没有研究考察增长/下降的任何趋势。目的：确定泰国儿童青春期生长和/或年龄是否存在任何增加/减少的长期趋势。方法：2012 年，对 3460 名儿童进行了一项生长横断面研究。将身高和体重的中位数以及青春期成熟的年龄与之前的研究进行比较。计算了长期趋势与健康统计指标之间的相关性。结果：从1975年到2012年，男孩和女孩的中位最终身高分别增加了1.32和0.86厘米/十年，体重分别增加了2.49和1.76公斤/十年。在女孩中，乳房初潮和初潮年龄分别下降了 0.39 岁/十年和 0.12 岁/十年。在男孩中，Tanner II 睾丸增大的年龄下降了 0.15 岁/十年。身体生长的增加与预期寿命、人均收入呈正相关，超重/肥胖的患病率与营养不良的患病率和五岁以下死亡率呈负相关。结论：泰国儿童生长速度加快和青春期开始年龄下降的长期积极趋势与泰国整体生活条件的改善相关。
Abstract Background: In Thailand, studies of growth date back to 1975, but there have been no studies examining any trends in increasing/decreasing growth. Aim: To determine if there have been any secular trends of increasing/decreasing growth and/or ages at puberty in Thai children. Methods: In 2012, a cross-sectional study of growth was conducted in 3460 children. The median heights and weights and the ages of pubertal maturation were compared with previous studies. Correlations between the secular trends and the health statistics indicators were calculated. Results: From 1975–2012, the median final height of boys and girls had increased by 1.32 and 0.86 cm/decade and weight by 2.49 and 1.76 kg/decade, respectively. In girls, the age at thelarche and menarche had declined by 0.39 and 0.12 years/decade, respectively. In boys, the age at testicular enlargement Tanner II had declined by 0.15 years/decade. Increased physical growth was positively correlated to life expectancy, per capita income and prevalence of overweight/obesity was negatively correlated to prevalence of malnutrition and under-five mortality rate. Conclusion: The positive secular trend towards an increase in growth and a decline in the age at onset of puberty of Thai children is correlated with improvements in overall living conditions in Thailand.
