The study included Tibetan school students aged 7\u201318\u2009years from testing sites in and around Lhasa, Tibet Autonomous Region, China, at an altitude of approximately 3600\u2009m. Height and weight were measured using standardized protocols, and BMI was calculated. Sex\u2010specific and age\u2010specific means and standard deviations were reported by survey year. Differences across years were assessed using one\u2010way analysis of variance, with temporal trend tests also performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      From 2005 to 2019, Tibetan children and adolescents showed an overall upward trend in height, weight, and BMI. For height, significant differences across survey years were observed in most age groups among both boys and girls, except for the group aged 16\u2009years (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.05). The greatest height gains occurred among boys aged 13\u2009years and girls aged 10\u2009years, indicating age\u2010specific heterogeneity in secular growth changes. Weight followed a broadly similar pattern: mean body weight in 2019 exceeded that in 2005 in most sex and age\u2010specific groups, with particularly marked increases among boys aged 13\u2009years and girls aged 10\u2009years. BMI increased gradually, with more evident gains in some age groups after 2010, although the magnitude of BMI change was smaller than that observed for height and weight. Concurrently, the number of participants classified as having height\u2010related growth retardation declined from 150 in 2005 to 35 in 2019, suggesting a substantial reduction in the burden of low stature and an overall improvement in population\u2010level growth status.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Despite continuous exposure to high altitude hypoxia, Tibetan children and adolescents experienced measurable improvements in physical growth between 2005 and 2019. These findings indicate that although hypoxia remains a key ecological constraint on growth at high altitude, its adverse effects may be partly buffered by enhanced nutritional security, school\u2010based dietary support, improved healthcare resources, and broader socioeconomic development.<\/jats:p>\n
