Abstract:
OBJECTIVE:To analyze the characteristics of the age at peak height velocity and peak height velocity of primary and middle school students in Zhongshan City, Guangdong Province, and to explore the law of the sudden increase in adolescent height in this area, and to understand the law of height growth spurt in adolescence by longitudinal tracking of the height of children and adolescents in Zhong-shan City.
METHODS:Based on the physical examination database of primary and middle school students in Zhongshan City, Guangdong Province from 2005 to 2016, individuals who had been continuously tracked for more than 6 times were selected as research samples. SITAR model was used to fit the height data of the sample population, and the age at peak height velocity and peak height velocity were calcula-ted.
RESULTS:A total of 49 579 subjects were included in this study, including 26 524 boys and 26 008 urban students. The median follow-up ages of boys and girls were 7.74 and 7.72 years, respectively. The boy's height spurt peak age was (12.72±0.89) years, and later than the girls at the age of (10.98±0.95) years (t=207.639, P < 0.001), the boy's height spurt peak velocity of (10.12±1.49) cm/year, higher than the girls of (8.35±1.12) cm/year (t=150.826, P < 0.001). The gender differences of height spurt peak age and height spurt peak speed in urban and rural students were consistent with the whole sample. The height surge peak age of urban male students was earlier than that of rural male students, and the height surge peak speed of urban female students was lower than that of rural female students.
CONCLUSION:The peak age of the surge of girls was earlier than that of boys, but the peak rate of the surge of girls was lower than that of boys, the peak age of urban students was earlier than that of rural students, but the peak rate of urban boys was lower than that of rural boys in Guangdong Province.
