Abstract:
Objective To analyze the secular trends and geographic disparities of all-cause mortality among Chinese adolescents aged 10-24 years over the period of 1953-2010.Methods Data were extracted from the Chinese National Census in 1953-2010.We calculated the all-cause mortality and annualized rates of the changes.Using the provincial gross domestic product (GDP) per capita as an indicator of regional socio-economic development level,we calculated the Wagstaff normal concentration indices for adolescent mortality.Results Over the period of 1953-2010,the general patterns of Chinese adolescent mortality appeared higher in males than those in females,higher in the 20-24-year-old than those in the 15-19 year-old and in the 10-14 year-old groups,higher in adolescents from the western than those in the eastern regions.The mortality of adolescents decreased from 554.6/100 000 in 1953-1964 to 55.7/100 000 in 2010 in males and decreased from 488.4/100 000 to 26.7/100 000 in females,respectively.The percentage of decrease for females (94.5％) was higher than that for males (90.0％).In 1981-2010,the highest annualized rate of decline for males was seen in Beijing (4.4％),with the lowest seen in Qinghai (0.1％).For girls,Hubei showed the highest annualized rate of decline (6.4％) while Qinghai the lowest (0.8％).Provinces that with higher mortality tended to have lower annualized rate of decline.The concentration indices for boys were-0.07 (95％ CI:-0.11--0.03),-0.13 (95 ％ CI:-0.18--0.08),and-0.16 (95 ％ CI:-0.22--0.10) in 1990,2000,and 2010,respectively,and were-0.07 (95％CI:-0.13--0.02),-0.18 (95％CI:-0.24--0.12),and-0.18 (95％CI:-0.26--0.09) respectively in girls.The indices among 1990,2000,and 2010 did not show statistically significantly differences,both for boys and girls (P＞0.05).Conclusions Over the half century,the mortality of Chinese adolescents showed dramatic decreasing trend.However,in terms of death rates,gender and geographic disparities were consistently seen in the adolescents.
