中国社区老年居民日常生活活动能力失能状况调查

目的 调查我国城乡社区老年人失能现状及其流行特征。方法 调查对象来自2015年老年期重点疾病预防和干预项目。采用多阶段分层整群随机抽样,抽取6省市共23 803名≥ 60岁城乡社区老年人,对其进行问卷调查和身体测量,采用日常生活活动能力量表（ADL）评估老年人失能情况。采用χ²检验分析基础性日常生活活动能力量表（BADL）和工具性日常生活活动能力量表（IADL）各项功能受损率及BADL/IADL失能率在不同特征老年人群间的差异,采用多因素logistic回归模型分析失能的影响因素。结果 BADL功能中洗澡受损率最高（1.7%）,吃饭受损率最低（0.6%）;IADL功能中打电话受损率最高（16.6%）,其次是乘公共汽车（5.5%）,吃药受损率最低（1.8%）。社区老年人BADL失能率2.1%,IADL失能率19.1%。BADL失能率在女性、无配偶、文盲、低体重和肥胖老年人中较高（P<0.05）。IADL失能率在女性、农村、无配偶、低文化程度和低体重老年人中较高（P<0.05）。多因素分析显示,BADL失能的危险性随年龄增加而升高,非正常体重也增加其危险性,而文化程度较高的老年人群BADL失能的危险性相对较低。增加IADL失能的危险因素有女性、增龄、农村、无配偶和低体重;而文化程度高和肥胖的老年人群IADL失能的危险性相对比较低。结论 本研究结果显示,受年龄老化和人口学诸多因素影响,我国老年人群失能率仍维持在一个高水平,加强老年人群躯体性的和工具性的日常生活活动能力下降预防和干预工作是非常必要的。     

中国城乡老年人群两年内日常生活活动能力受损发生情况及影响因素

目的 了解中国城乡社区老年人群2年内日常生活活动能力（ADL）下降情况及其影响因素。方法 调查对象来自老年期重点疾病预防和干预项目。该调查采用多阶段分层整群随机抽样的方法,于2015年从我国6个省份抽取23 803名研究对象进行基线调查,2017年进行随访,剔除死亡、失访、数据不完整和2015年基线调查ADL受损的研究对象后,共计18 785名≥ 60岁的老年人符合纳入标准。以第6次全国人口普查数据为标准人口对样本数据进行加权后,分析不同特征老年人群2年内ADL、基础性日常生活活动能力（BADL）和工具性日常生活活动能力（IADL）受损发生率,并采用多因素logistic回归模型分析相关影响因素。结果 经过2年的随访,队列人群中共有1 959例发生ADL受损,ADL受损的2年累计发生率为12.0%,其中,BADL受损的2年累计发生率为1.6%,仅IADL受损的2年累计发生率为10.4%。多因素logistic回归模型分析结果显示,增加仅BADL受损发生风险的因素是年龄增加、肥胖、≥ 2种共病以及认知功能异常;增加仅IADL受损发生风险的因素为年龄增加、女性、低体重和认知功能异常。降低仅IADL受损发生风险的因素包括小学或初中及以上文化程度、超重或肥胖。结论 年龄增加、认知功能异常均增加BADL和IADL受损发生的风险。患有≥ 2种疾病的老年人BADL受损风险较高;肥胖增加老年人BADL受损发生风险,但降低IADL受损发生风险;女性比男性发生IADL受损风险高;高文化程度的老年人IADL受损风险低。

老年人抑郁症状与慢性病及日常生活活动能力的关联性研究

目的 分析老年人慢性病、抑郁症状及日常生活活动能力三者之间的相互关系,探讨老年人抑郁症状和老年人日常生活活动能力受限的危险因素.方法 采用多阶段整群抽样方法,应用老年抑郁短量表、Katz日常生活活动量表（Katz-ADL）和Lawton工具性日常生活活动量表（Lawton-IADL）,对济宁市部分县区≥65岁的504例老年人进行问卷调查.结果 济宁市部分县区老年人总患病率为74.01％,抑郁症状阳性率为7.14％,ADL、IADL功能受限率分别为19.05％和66.67％,男性老年人抑郁症状阳性率及ADL、IADL功能受限率低于女性（x2分别为18.15、12.31、30.18,P均＜0.05）;老年人现患有慢性病的种类数是抑郁症状和ADL受限的危险因素（OR分别为1.71、1.53）,ADL和IADL受限也是老年人抑郁症状的危险因素（OR分别为3.15、9.36）;控制性别、年龄因素后,患有慢性病种类数对老年人抑郁症状、ADL、IADL的影响以及ADL和IADL受限对老年人抑郁症状的影响均无统计学意义.结论 性别、年龄是老年人抑郁症状、ADL和IADL受限的最根本的危险因素,家庭和社会在对老年人照护时,应积极锻炼提高老年人的日常生活活动能力,提升老年人的正性情绪,减少抑郁症状的发生.     

老年人日常生活活动能力损害及其影响因素分析

日常生活活动能力是评价老年人独立生活能力最重要的指标。WHO指出老年人健康评价的主要指标不应只是死亡和患病指标,能否独立生活应成为主要的健康状况指标。本研究重点探讨老年人日常生活活动能力损害的有关因素,为今后采取预防和干预措施提供决策依据。

Biometric indicators can be early signs of declines in activities of daily living functioning among the Indonesian elderly

BackgroundSigns associated with the onset of disability can be useful in disability projection and have significant implications in elderly care policy.ObjectiveTo explored the associations between biometric screening indicators and declines in activities of daily life (ADLs) functioning among the Indonesian elderly.MethodsThis is a prospective longitudinal cohort study. The Indonesian Family Life Survey (IFLS) 4 conducted in 2007–2008, and IFLS 5 conducted in 2014–2015 were used to assess the association between biometric indicators and ADLs at baseline and follow-up.ResultsFindings revealed that 22.3% of participants surveyed in 2007–2014 had become disabled in terms of ADLs. Anemia status, stage 2 hypertension, lung capacity, and a longer sit-to-stand time were associated with ADLs.ConclusionThese findings are important to help early detection and potentially help the prevention of ADLs in elderly people in the future. Accuracy of disability estimation could possibly be improved if including biometric parameters.     

中国9省市中老年人群体重指数与健康相关生命质量的关系

Objective To study the association between body mass index (BMI) and the health-related quality of life (HRQOL) in the middle-aged and older Chinese people. Methods Data of 9539 middle-aged and older adults was collected from a cross-sectional survey performed in 9 provinces of China (Jiangsu, Anhui, Gansu, Qinghai, Fujian, Beijing, Jilin, Jiangxi and Henan province). MO SSF-36 was used to measure HRQOL. BMI classification was in accordance with the criteria recommended by the Ministry of Health of China. Rank sum test was used to compare HRQOL between subjects with normal weight and those with different BMI classification. Multiple logistic regression analysis was used to assess the association of HRQOL with BMI after adjusted for sex, age, marital, education, physical activity status and chronic diseases. Results When compared with middle-aged and older adults at normal weight range (18.5≤BMI<24) , data on physical domain (P<0.001) , mental domain (P< 0.01) and 8 dimensions of HRQOL (physical functioning, mental health, P<0.05; role-physical, bodily pain, general health, vitality, social functioning, role-emotional, P<0.01)among subjects with underweight (BMI<18.5) were significantly lower while mental component summary (P<0.05) of overweight subjects (24≤BMI<28) was significantly higher. Obese subjects (BMI≥28) had worse physical function (physical functioning, P<0.01) but better mental health (mental health, P<0.01; mental component summary, P<0.05). After adjusting for other factors, and compared to middle aged and older adults with normal weight, data on odds ratios (ORs) of impaired HRQOL in physical domain (OR=1.67, 95% CI: 1.35-2.06), mental domain (OR=1.39, 95%CI: 1.13-1.70) and 8 dimensions increased among underweight subjects while ORs of impaired HRQOL in mental domain (0R=0.86,95% CI: 0.78-0.95) and role-physical, vitality, social functioning, role-emotional and mental health dimensions decreased among overweight subjects. ORs increased (OR=1.51,95% CI: 1.27-1.80) in impaired HRQOL in physical functioning dimension but decreased in mental domain (OR=0.71,95%CI: 0.60-0.85) as well as vitality, role-emotional and mental health dimensions among obese subjects. Conclusion HRQOL of each domain were different among middle aged and older adults with different BM1 classification. Underweight people had poor HRQOL in both physical domain and psychological domain, and obese people had poor physical function but good mental health condition.

Results When compared with middle-aged and older adults at normal weight range (18.5≤BMI<24) , data on physical domain (P<0.001) , mental domain (P< 0.01) and 8 dimensions of HRQOL (physical functioning, mental health, P<0.05; role-physical, bodily pain, general health, vitality, social functioning, role-emotional, P<0.01)among subjects with underweight (BMI<18.5) were significantly lower while mental component summary (P<0.05) of overweight subjects (24≤BMI<28) was significantly higher. Obese subjects (BMI≥28) had worse physical function (physical functioning, P<0.01) but better mental health (mental health, P<0.01; mental component summary, P<0.05). After adjusting for other factors, and compared to middle aged and older adults with normal weight, data on odds ratios (ORs) of impaired HRQOL in physical domain (OR=1.67, 95% CI: 1.35-2.06), mental domain (OR=1.39, 95%CI: 1.13-1.70) and 8 dimensions increased among underweight subjects while ORs of impaired HRQOL in mental domain (0R=0.86,95% CI: 0.78-0.95) and role-physical, vitality, social functioning, role-emotional and mental health dimensions decreased among overweight subjects. ORs increased (OR=1.51,95% CI: 1.27-1.80) in impaired HRQOL in physical functioning dimension but decreased in mental domain (OR=0.71,95%CI: 0.60-0.85) as well as vitality, role-emotional and mental health dimensions among obese subjects. Conclusion HRQOL of each domain were different among middle aged and older adults with different BM1 classification. Underweight people had poor HRQOL in both physical domain and psychological domain, and obese people had poor physical function but good mental health condition.
