The aim of this study was to determine the magnitude of the association between perceived oral and general health-related quality of life (O/HRQoL) in the German general population and to compare it with the correlation of both constructs in dental patients.
OHRQoL was assessed using the OHIP-49 and HRQoL using the SF-36 in a sample (N=811) representative of the adult general population of Germany (age: 18-99 years), and in a sample (N=313) of consecutive adult dental patients at least 18 years of age seeking prosthodontic care or attending their annual checkup. Correlation between OHRQoL and HRQoL was computed using structural equation modelling-based confirmatory factor analysis and path analysis. Based on the correlation coefficients, the coefficients of determination (r(2)) were calculated.
Correlation between OHRQoL and HRQoL after partialling out effects of age, gender and level of depression in general population subjects was rho=0.28 resulting in an explanation of the variance of HRQoL by OHRQoL of 7.8%. In dental patients the correlation coefficient was somewhat lower (rho=0.24) corresponding to an explanation of the variance of HRQoL by OHRQoL of 5.6%. Difference between correlation coefficients was not significant (p=0.514).
Our findings provide evidence for the inseparable, intertwined relationship between perceived oral and general health.
本研究旨在确定德国普通人群中感知口腔和一般健康相关生活质量（O/HRQoL）之间的关联程度，并将其与牙科患者中两种结构的相关性进行比较。
使用 OHIP-49 评估 OHRQoL，使用 SF-36 评估 HRQoL，样本来自德国成年普通人群（年龄：18-99 岁）的代表性样本（N=811），以及至少 18 岁寻求修复治疗或参加年度检查的连续成年牙科患者的样本（N=313）。使用基于结构方程建模的验证性因子分析和路径分析计算 OHRQoL 和 HRQoL 之间的相关性。基于相关系数，计算决定系数（r(2)）。
在排除一般人群中年龄、性别和抑郁程度的影响后，OHRQoL 和 HRQoL 之间的相关性为 rho=0.28，这意味着 OHRQoL 可以解释 HRQoL 方差的 7.8%。在牙科患者中，相关系数略低（rho=0.24），这意味着 OHRQoL 可以解释 HRQoL 方差的 5.6%。相关系数的差异无统计学意义（p=0.514）。
我们的研究结果提供了证据，证明了感知口腔和一般健康之间不可分割、相互交织的关系。
