Background Disabilities caused by perinatal asphyxia will burden child health and well-being. To date, our understanding about the situation and risk factors of perinatal asphyxia-induced disabilities among Chinese children is still limited. Objectives To evaluate the prevalence and socio-demographic risk factors of disabilities caused by perinatal asphyxia among Chinese children in 2006 and compare disability trajectories across different socio-demographic status. Methods Cross-sectional data came from the 2006 China National Survey on Disability which includes a total of 616,940 children aged 0– 17 years old was employed in the investigation. Perinatal asphyxia-induced disabilities were identified by following the guidance in consensus manuals. Population-weighted numbers and prevalence rates were investigated, and multivariable logistic regression was performed to evaluate associations between disabilities and socio-demographic factors. Adjusted predictions at representative values were computed to compare the disability trajectories relative to significant socio-demographic variables. Results The prevalence rate of disabilities caused by perinatal asphyxia was 7.70 per 10,000 children (95% CI: 7.01– 8.39). Male (OR 1.81, 95% CI: 1.47– 2.23) and low family income (OR: 1.73, 95% CI: 1.21– 2.49) have higher and the increase of per additional year of age (OR: 0.89, 95% CI: 0.88– 0.91) has lower probability of being disabilities caused by perinatal asphyxia. Further disability trajectories showed that differences in probability between gender and family income group were more evident before age 7 and weakened with increasing age. Conclusions Our results showed that both demographic and socioeconomic characteristics are risk factors for disabilities caused by perinatal asphyxia. Of these, gender and family income have much higher impact than other factors on the prevalence rate of disabilities caused by perinatal asphyxia at infants and young children. Multiple society sectors should increase their effort to bring about fundamental social change to prevent disabilities caused by perinatal asphyxia, especially concerning younger children and their families.

准确认识和把握我国老年人认知障碍的变化趋势和影响趋势变化的关键因素,对于相关规划和政策的制定至关重要。本研究采用中国老年健康影响因素跟踪调查在2002— 2019年间的六轮数据,分析了我国65— 105岁老年人认知障碍患病率的变化趋势,重点探索了教育水平提高对认知障碍趋势的影响及其性别差异。结果显示,在控制人口年龄结构的影响后,我国老年人认知障碍患病率呈现明显的下降趋势,认知障碍标准化患病率从2002年的14 3%下降到2017— 2019年的10.2%,下降了28.7%;老年人受教育水平的提高是这一下降趋势的主要影响因素,可解释下降62%的原因,且这一影响存在显著的性别差异。研究结果提示,通过早期...

本文利用2016— 19年全国残疾人人口基础数据库持证残疾人数据,研究持证残疾老年人群体全国、城乡以及省份等不同层次的贫困状况和特征,并从城乡和地域上进行分解。结果表明:(1)全国范围内残疾老年人经济贫困率下降明显,至2019年,绝对贫困发生率仅6.5%,但边缘贫困问题开始凸显,且具有较明显城乡和区域差异。(2)农村残疾老年人多维贫困程度较城市更为严重,趋势整体向好,农村改善速度快于城市。(3)西部地区残疾老年人贫困状况依然相对更为严峻,具有较高的边缘贫困率及程度较深的多维贫困。东部地区整体经济发展水平虽较高,但部分省市开始出现城市边缘贫困加剧与多维贫困加深的现象,还可能面临城乡残疾老年人多维贫...
