Objective To understand the causes of death in children and adolescents at 5-19 years of age from 2004 to 2013 in Cixi City. Method According to data of diseases surveillance in Cixi City during the 10 years, the health indexes of mortality, potential years of life lost (PYLL), potential years of life lost rate (PYLL‰), standardized potential years of life lost (SPYLL), standardized potential years of life lost rate (SPYLL‰) were applied to analyze the causes of death and evaluate the burdens of mortality. Result The total mortality of the children and adolescents was 25.56/105, and standardized mortality was 25.26/105. Boys had higher mortality (33.20/105) than girls (17.91/105), and there was statistical significance in the prevalence between male and female. Death of injury&poisoning (13.77/105) and tumors (5.78/105) respectively ranked at the first two leading causes, accounting for 76.46%of total deaths. PYLL was 24 624 years, standardized PYLL was 37 417.02 years, and the rate of PYLL was 2.59‰. Conclusion Injury, poisoning and tumors were the major risk factors among children and adolescents aged 5-19 years in Cixi City. Therefore, effective measures should be taken to strengthen the preventive force and promote the development of comprehensive mental and physical pediatric care.

Objective To ascertain the mortality situation and main causes of deaths among children under five years of age from 2006 to 2013 in Cixi City.Methods The data of children under 5 years of age who died mortality cases in Cixi City from 2006 to 2013 were analyzed according to the international classification of disease (ICD-10).Results From 2006 to 2013,the mortality rate of chiildren under 5 years of age was 6.99‰-3.61‰ in Cixi City,while the mortality rate of infant was 1.97‰-5.18‰ and newborn infants was 0.90‰-3.38‰.The top 5 causes of death were accidental death,congenital heart disease,other congenital malformations,preterm birth weight and birth asphyxia,which accounted for 73.3％ (195/266),while in newborns mainly with low birth weight (30.0％,33/110),and infants with congenital heart disease (21.6％,38/176).The neonatal deaths accounted for 62.5％ of infant deaths,and the infant deaths accounted for 66.2％ of under 5 mortality rate.Conclusion Under 5 mortality rate in Cixi City from 2006 to 2013 fluctuated,but overall there was a downward trend.Using various measures to reduce accidental deaths among children and infants should be the main strategy for reducing mortality in children under 5 years of age in Cixi City.

Objective:To assess the effectiveness of a 6-month Ba Duan Jin exercise program in improving the balance of community-dwelling older adults.Methods:A two arms, parallel-group, cluster randomized controlled trial was conducted in 1 028 community residents aged 60-80 years in 40 communities in 5 provinces of China. Participants in the intervention group (20 communities, 523 people) received Ba Duan Jin exercise 5 days/week, 1 hour/day for 6 months, and three times of falls prevention health education, and the control group (20 communities, 505 people) received falls prevention health education same as the intervention group. The Berg balance scale (BBS) score was the leading outcome indicator, and the secondary outcome indicators included the length of time of standing on one foot (with eyes open and closed), standing in a tandem stance (with eyes open and closed), the closed circle test, and the timed up to test.Results:A total of 1 028 participants were included in the final analysis, including 731 women (71.11%) and 297 men (28.89%), and the age was (69.87±5.67) years. After the 3-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 3.05 (95% CI: 2.23-3.88) points ( P<0.001). After the 6-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 4.70 (95% CI: 4.03-5.37) points ( P<0.001). Ba Duan Jin showed significant improvement ( P<0.05) in all secondary outcomes after 6 months of exercise in the intervention group compared with the control group. Conclusions:This study showed that Ba Duan Jin exercise can improve balance in community-dwelling older adults aged 60-80. The longer the exercise time, the better the improvement.
