选择空气氟均值为0.553mmol/L、水氟低于0.053mmol/L的台沟村儿童少年566人为调查对象。另选空气氟均值为0.237mmol/L,水氟浓度与台沟村相似的郑州郊区十八里河儿童少年869人为对照。结果:骨龄延迟率台沟村男性为49.18%,女性为44.62%,两区之间差异非常显著(P<0.01)。背肌力:台沟村男性11～14岁年龄组比对照组减少4.9～10.3kg,女性11～15岁年龄组比对照组减少6.5～18.2kg,其中男性差异有显著性(P<0.05),女性差异有非常显著性(P<0.01)。显示:台沟村较对照区男、女儿童少年骨龄发育延迟。身体形态机能指标以背肌力、体重影响显著。
A total of 566 children and adolescents in Taigou village were chosen as subjects for the study. Air fluoride content was 0.553 mmol / L and water fluoride content was less than 0.053 mmol / L. Alternative air fluoride average of 0.237mmol / L, water fluoride concentration and Taigou similar Zhengzhou Shibalihe children and adolescents 869 as a control. Results: The delayed rate of bone age in Taigou Village was 49.18% for males and 44.62% for females. The difference between the two regions was significant (P <0.01). The back muscle strength of Taitou Village was decreased by 4.9 ~ 10.3kg in the 11-14 age group and 6.5 ~ 18.2kg in the 11-15 age group than in the control group, and the difference was significant among males (P <0.05) , There was a significant difference between females (P <0.01). The results showed that there was a delay in the development of skeletal age between male and female children and adolescents in Tugou Village. Physical performance indicators to the back strength, weight significant impact.
