Study on the Prevalence of Stunting and its Influencing Factors among Tibetan Ad-olescents at Different Altitudes in Xizang
Objective To investigate the prevalence of stunting among Tibetan adolescents at different altitudes in Ti-bet and to analyse the influencing factors.Methods In 2017,993 Tibetan adolescent students aged 11～18 were select-ed from middle schools in four counties at different altitudes in Xizang and a questionnaire survey was used to collect the general condition of the students and followed by physical examinations.Continuous variables were described as mean and standard deviation(normally distributed),categorical variables were described as frequency and rate(per-centage),t-test or ANOVA were used for comparison of means,and x2 test was used for comparison of rates.In order to control the influence of confounding factors,poisson regression was used for multivariate analysis.Results Ac-cording to the results of this survey,133 people(13.4％)were diagnosed with growth retardation.The results of univar-iate analysis showed that the detection rate of stunting was the highest among students aged 15.0～17.9 years old,male,born in order of the third child or above,with father who had never gone to school,had three or more children in the family and had a monthly family income less than 1000yuan.The multivariate results showed that the detection rate of growth retardation in students aged 13.0～14.9 and 15.0～17.9 years was 1.662 times and 2.574 times that of stu-dents aged 11.0～12.9 years,respectively.The detection rate of stunting in students with 2 children and 3 or more chil-dren in the family was 2.989 times and 3.222 times that of 1 child,respectively.The detection rates of stunting in the high-altitude to low-altitude group,the high-altitude group,and the low-altitude to high-altitude group were 1.913 times,5.380 times,and 5.872 times higher than those in the low-altitude group,respectively.Conclusion Altitude is the main influencing factor for stunting in Tibetan adolescents,and age and the number of children in one family also have an impact on stunting.
