Disease varies in different populations based on sociodemographic variables, and there is limited understanding of this interaction. The purpose of this methodological study was to determine the validity of the Oral Health Status Index, a disease-based index, on a Hispanic population by comparing it with the NIDCR epidemiological measures of disease, with the addition of demographic and behavioral variables. The epidemiologic data were collected according to the criteria defined by the NIDCR, including: a modified Decayed Missing Filled Surfaces Index, gingival inflammation, calculus, and destructive periodontal disease measures. The demographic and behavioral variables were gathered from 240 interviews with Hispanic adults in two community clinics. Bivariate analysis was used to determine relationships between the descriptive epidemiologic, demographic, and behavioral variables and the Oral Health Status Index (OHSI). There were statistically significant differences (p < 0.05) in mean OHSI scores among the demographic variables age, education, income, and place of birth; and the behavioral variables alcohol consumption, flossing, and acculturation. Multiple regression analysis with the OHSI as the dependent variable showed that the statistically significant (p < 0.001) epidemiologic predictors were: percentage of Decayed Teeth/Decayed, Filled Teeth; Number of Replaced Teeth/Missing Teeth; and millimeters of mesial attachment loss. These collectively explained 47.49% of the variance in the regression. The addition of demographic variables to the epidemiologic regression identified age (p < 0.05), gender (p < 0.01), and place of birth (p < 0.01) as significant predictors that explained an additional 4.12% of the variance, collectively bringing the total explained variance to 51.61%. The behavioral variables did not contribute significantly to predicting the OHSI regression score. The Oral Health Status Index in this study is validated by its correlation with both the epidemiologic measures and the demographic variables. This combination of variables separated the Hispanics into Mexicans and Central/South Americans.
疾病在不同人群中因社会人口统计学变量而异，人们对这种相互作用的了解有限。本方法学研究的目的是通过将基于疾病的口腔健康状况指数与美国国立牙科和颅面研究所（NIDCR）的疾病流行病学测量方法进行比较，并增加人口统计学和行为变量，来确定该指数在西班牙裔人群中的有效性。流行病学数据是根据NIDCR定义的标准收集的，包括：改良的龋失补牙面指数、牙龈炎症、牙石和牙周破坏疾病测量。人口统计学和行为变量来自对两个社区诊所的240名西班牙裔成年人的访谈。双变量分析用于确定描述性流行病学、人口统计学和行为变量与口腔健康状况指数（OHSI）之间的关系。在年龄、教育程度、收入和出生地等人口统计学变量，以及饮酒量、使用牙线和文化适应等行为变量之间，OHSI平均得分存在统计学显著差异（p < 0.05）。以OHSI为因变量的多元回归分析表明，具有统计学显著性（p < 0.001）的流行病学预测因素为：龋牙/龋补牙百分比；换牙数/缺牙数；以及近中附着丧失毫米数。这些因素共同解释了回归中47.49%的方差。在流行病学回归中加入人口统计学变量后，年龄（p < 0.05）、性别（p < 0.01）和出生地（p < 0.01）被确定为显著预测因素，它们共同解释了另外4.12%的方差，使总解释方差达到51.61%。行为变量对预测OHSI回归得分没有显著贡献。本研究中的口腔健康状况指数通过与流行病学测量方法和人口统计学变量的相关性得到了验证。这种变量组合将西班牙裔人群分为墨西哥人和中/南美洲人。
