Few studies distinguish between the effects of different forms of social capital on health and of those that do none use physical indicators of health as an outcome variable. The objective of this study was to determine whether vertical and horizontal social capital had different associations with dental status of elderly Japanese. In this cross-sectional study, self-administered questionnaires were mailed to elderly individuals living in 25 Japanese communities in 2003. Data from 5560 respondents (49.9%, 72.9+/-6.0 years) included information on social capital, numbers of remaining teeth, health behaviors, physical and mental health, and socioeconomic status. Vertical social capital was defined as participating in groups which encouraged hierarchical relations and horizontal social capital as participating in groups of equals. A multilevel logistic regression analysis was conducted to assess the association between social capital and number of remaining teeth (< or = 19 teeth or > or = 20 teeth). The prevalence of people with 19 or less teeth was 70.7%. Univariate analysis showed significant beneficial associations between individual horizontal social capital and number of remaining teeth. After adjusting for individual- and community-level covariates in multilevel analysis, community-level horizontal social capital still showed beneficial association. Compared to respondents living in highest horizontal social capital areas, those living in lowest horizontal social capital areas had a 1.25 times higher odds ratio for having 19 or less teeth. Individual-level horizontal social capital also showed beneficial effects on number of remaining teeth. Community- and individual-level vertical social capital did not show significant associations with dental status. The results suggest that horizontal social capital, not vertical social capital, has beneficial effects on numbers of remaining teeth in older Japanese adults.
很少有研究区分不同形式的社会资本对健康的影响,而且那些进行区分的研究中,没有一项将健康的身体指标作为结果变量。本研究的目的是确定纵向和横向社会资本与日本老年人牙齿状况之间是否存在不同的关联。在这项横断面研究中,2003年向居住在日本25个社区的老年人邮寄了自填式问卷。5560名受访者(49.9%,年龄72.9±6.0岁)的数据包括社会资本、剩余牙齿数量、健康行为、身心健康以及社会经济地位等信息。纵向社会资本被定义为参与鼓励等级关系的群体,横向社会资本被定义为参与平等群体。进行了多水平逻辑回归分析,以评估社会资本与剩余牙齿数量(≤19颗或≥20颗)之间的关联。牙齿数量为19颗或更少的人群患病率为70.7%。单因素分析显示个体横向社会资本与剩余牙齿数量之间存在显著的有益关联。在多水平分析中对个体和社区层面的协变量进行调整后,社区层面的横向社会资本仍显示出有益关联。与生活在横向社会资本最高地区的受访者相比,生活在横向社会资本最低地区的受访者牙齿数量为19颗或更少的比值比高1.25倍。个体层面的横向社会资本对剩余牙齿数量也显示出有益影响。社区和个体层面的纵向社会资本与牙齿状况没有显著关联。结果表明,对日本老年人的剩余牙齿数量有有益影响的是横向社会资本,而非纵向社会资本。
