不同健康状况的中老年人社会资本量表的信度及效度评价

目的 评价中老年人社会资本量表的信效度，探索其在不同健康状况的中老年人群间的区分度。方法 针对已编制的中老年人社会资本量表，采用多阶段分层随机抽样方法，在四川省成都市及泸州市共抽取1 367名50岁及以上中老年居民进行问卷调查。运用Cronbach’s α系数、Pearson相关系数、t检验、探索性因子分析等方法评价量表的信度和效度。结果 1 367名中老年调查对象的社会资本量表总Cronbach’s α系数为0.67，各维度条目与总分的相关系数在0.30～0.79之间，具有良好的信度；探索性因子分析表明，14个条目提取出5个特征根大于1的因子，累积方差贡献率为68.84%；现患慢性疾病的中老年病例组人群的个人社会资本得分、家庭社会资本得分、社团社会资本得分、社区社会资本得分及社会资本总得分均低于未患病的对照人群组，宏观社会资本得分高于对照人群组，且差异均有统计学意义 (均 P＜0.01)，提示该量表具有较好的区分度。结论 中老年人社会资本量表具有较好的信度和效度，且对不同健康状况的50岁及以上中老年人中有较好的区分度。     

多力视角下社会资本参与基层卫生服务的动力机制及优化策略研究

社会办医作为我国基层卫生服务的重要组成部分,可以弥补基层卫生机构发展总量与质量不足等问题,对于推进整个基层卫生服务高质量发展也是有着重大裨益。文章从物理学的"力"出发,运用支持力,推力,引力,阻力,摩擦力五种"力"探讨社会资本参与基层卫生服务的动力形成机制,并构建动力斜坡图,针对存在问题,提出加大支持力和引力,合理利用推力,减少摩擦力,消除阻力等优化建议,以期助力社会资本参与基层卫生服务建设平稳进行。     

重视医学信用伦理的研究与开发

医疗行业市场化是必然趋势。在医疗行业市场化进程中，医学伦理道德除了道德价值之外，还含有积极的经济内涵。医学伦理道德也是重要的医疗资源，通过参与医疗市场资源的配制和运作，也可以产生经济效益，转化为医疗资本。医疗行业要重视医学伦理道德资源的开发。信用伦理是在市场经济条件下形成的，这是医学伦理学所面临的新课题。笔者认为，不说谎、不期诈，兑现承诺，保证医疗质量，发扬医学人道主义，是医学信用伦理的四项基本标准。     

Subcapital callus resection for slipped capital femoral epiphysis

Surgical Principles The lateral approach is routinely combined with an osteotomy of the greater trochanter. We resect the newly formed callus located at the anterior, posterior and caudal aspect of the femoral neck distal to the epiphysis. No shortening of the femoral neck results from this procedure. One can safely avoid a vascular injury by performing a careful dissection, since the posteriorly reflected articular capsule containing the nutrient vessels to the head is detached from the femoral neck like a banana peel. The resection manoeuvre is performed next to the physeal plate of the slipped epiphysis. After callus resection, reduction of the femoral head by longitudinal traction and internal rotation of the limb is easy. The aim is complete correction of the slippage. When there is excess physeal cartilage, we resect it with a curette and then the head is fixed using 2 screws. Revised Version from: Operat. Orthop. Traumatol. 4 (1992), 77–85 (German Edition).     

On the Importance of Age-Adjustment Methods in Ecological Studies of Social Determinants of Mortality

Objective. To illustrate the potential sensitivity of ecological associations between mortality and certain socioeconomic factors to different methods of age-adjustment.
Data Sources. Secondary analysis employing state-level data from several publicly available sources. Crude and age-adjusted mortality rates for 1990 are obtained from the U.S. Centers for Disease Control. The Gini coefficient for family income and percent of persons below the federal poverty line are from the U.S. Bureau of Labor Statistics. Putnam's (2000) Social Capital Index was downloaded from http://www.bowlingalone.com ; the Social Mistrust Index was calculated from responses to the General Social Survey, following the method described in Kawachi et al. (1997) . All other covariates are obtained from the U.S. Census Bureau.
Study Design. We use least squares regression to estimate the effect of several state-level socioeconomic factors on mortality rates. We examine whether these statistical associations are sensitive to the use of alternative methods of accounting for the different age composition of state populations. Following several previous studies, we present results for the case when only mortality rates are age-adjusted. We contrast these results with those obtained from regressions of crude mortality on age variables.
Principal Findings. Different age-adjustment methods can cause a change in the sign or statistical significance of the association between mortality and various socioeconomic factors. When age variables are included as regressors, we find no significant association between mortality and either income inequality, minority racial concentration, or social capital.
Conclusions. Ecological associations between certain socioeconomic factors and mortality may be extremely sensitive to different age-adjustment methods.     

家庭社会经济地位对青少年主观幸福感影响的多重中介效应分析

目的:探讨家庭社会经济地位与青少年主观幸福感的关系及领悟社会支持和积极心理资本的中介作用。方法:采用家庭社会经济地位问卷、幸福感指数量表、领悟社会支持量表和积极心理资本问卷调查了932名青少年。结果:(1)家庭社会经济地位、领悟社会支持、积极心理资本和主观幸福感两两之间相关显著;(2)家庭社会经济地位对主观幸福感的直接效应不显著,但领悟社会支持、积极心理资本在家庭社会经济地位与主观幸福感之间的三条中介路径均显著。结论:为提升低家庭社会经济地位青少年主观幸福感,改善其领悟社会支持和积极心理资本水平是可实现的有效路径。

Associations of social capital with binge drinking in a national sample of adults: The importance of neighborhoods and networks

BackgroundWhile considerable research on adult binge drinking has focused on social influences, the potential role of social capital has been largely overlooked. This study examines the role of social capital, assessed in terms of both neighborhood and social network characteristics, in understanding adult binge drinking.MethodsAdults ages 30–80 were randomly drawn from the RAND American Life Panel and completed an online survey (analytic sample n = 1383). The main predictor variables were neighborhood cohesion, neighborhood order, and social network density. Associations of social capital with past month binge drinking (any, number of days) were examined, controlling for demographic characteristics.ResultsZero-inflated negative binominal regression analysis indicated that any binge drinking was more likely among adults who lived in highly ordered neighborhoods and who had denser social networks but was negatively associated with neighborhood cohesion. However, binge drinking was more frequent among those who lived in neighborhoods lacking order and who had sparser social networks, but had no association with neighborhood cohesion. Age was not found to moderate associations of social capital with binge drinking.ConclusionsGiven that the associations of social capital with adult binge drinking behavior appear to differ by level of influence and type of drinking behavior, there is a need to gain a more nuanced understanding of these complex associations, including the mechanisms through which they operate.
