Oral Health Indicators (oral + health_indicator)
Selected AbstractsFactor structure of a conceptual model of oral health tested among 65-year olds in Norway and SwedenCOMMUNITY DENTISTRY AND ORAL EPIDEMIOLOGY, Issue 2 2010Anne Nordrehaug Åstrøm Åstrøm AN, Ekbäck G, Ordell S. Factor structure of a conceptual model of oral health tested among 65-year olds in Norway and Sweden. Community Dent Oral Epidemiol 2010. © 2010 John Wiley & Sons A/S Abstract,,, Background:, No studies have tested oral health-related quality of life models in dentate older adults across different populations. Objectives:, To test the factor structure of oral health outcomes within Gilbert's conceptual model among 65-year olds in Sweden and Norway. It was hypothesized that responses to 14 observed indicators could be explained by three correlated factors, symptom status, functional limitations and oral disadvantages, that each observed oral health indicator would associate more strongly with the factor it is supposed to measure than with competing factors and that the proposed 3-factor structure would possess satisfactory cross-national stability with 65-year olds in Norway and Sweden. Methods:, In 2007, 6078 Swedish- and 4062 Norwegian adults borne in 1942 completed mailed questionnaires including oral symptoms, functional limitations and the eight item Oral Impacts on Daily Performances inventory. Results:, Model generation analysis was restricted to the Norwegian study group and the model achieved was tested without modifications in Swedish 65-year olds. A modified 3-factor solution with cross-loadings, improved the fit to the data compared with a 2-factor- and the initially proposed 3-factor model among the Norwegian [comparative fit index (CFI) = 0.97] and Swedish (CFI = 0.98) participants. All factor loadings for the modified 3-factor model were in the expected direction and were statistically significant at CR > 1. Multiple group confirmatory factor analyses, with Norwegian and Swedish data simultaneously revealed acceptable fit for the unconstrained model (CFI = 0.97), whereas unconstrained and constrained models were statistically significant different in nested model comparison. Conclusions:, Within construct validity of Gilbert's model was supported with Norwegian and Swedish 65-year olds, indicating that the 14-item questionnaire reflected three constructs; symptom status, functional limitation and oral disadvantage. Measurement invariance was confirmed at the level of factor structure, suggesting that the 3-factor model is comparable to some extent across 65-year olds in Norway and Sweden. [source] Subjective food intake ability in relation to maximal bite force among Korean adultsJOURNAL OF ORAL REHABILITATION, Issue 3 2009B. I. KIM Summary, This study examined the relationship between the subjective food intake of 30 food types and their objective bite force to identify the key food items within the 30 food types to achieve a greater depth of masticatory function in Korean adults. A sample of 308 (112 males and 196 females) adults over the age of 20 (average age, 48·6) was selected among patients who visited four dental hospitals in Seoul, Korea. The subjective masticatory ability was evaluated through an interview with food intake ability questionnaires consisting of 30 food types ranging from hard to soft using a five-step Likert scale. The objective maximal bite force was measured using pressure-sensitive films. The relationship between the food intake ability and bite force was analysed and stratified according to age, gender, number of post-canine teeth lost and several clinical oral health indicators. The key foods were selected using correlation and factor analysis. The subjective food intake ability between the 30 foods and key foods were tested by cluster and one-way anova analysis. The Pearson's correlation coefficient between food intake ability and bite force was 0·45 (P < 0·01). The five key food items selected were dried cuttlefish, raw carrot, dried peanut, cubed white radish kimchi and caramel. The correlation coefficient between the food intake ability and bite force of these items was 0·51 (P < 0·01). These results suggest that the subjective food intake ability using the 30 and five key foods can be used to evaluate the masticatory function in Korean adults. [source] Self-reported and clinically determined oral health status predictors for quality of life in dentate older migrant adultsCOMMUNITY DENTISTRY AND ORAL EPIDEMIOLOGY, Issue 1 2008R. Mariño Abstract,,, Objective:, This paper reports the impact of oral health on the quality of life (QOL) of Southern European, dentate older adults, living independently in Melbourne, Australia. Participants were recruited through ethnic social clubs and interviewed about oral health, general health, socio-demographics, and QOL using the Medical Outcomes Study Short-Form 12 (SF-12). The SF-12's physical and mental health component summary scores (PCS and MCS, respectively) were computed. The Oral Health Impact Profile (OHIP-14) assessed the specific impact of oral health on QOL. Participants were also given a clinical oral examination. Results:, A total of 603 eligible older adults volunteered; 308 were from Greek background and 295 were from Italian background. Mean age was 67.7 years (SD 6.2), with 63.7% being female. The PCS score had a mean value of 45.8 (SD 11.8), and MCS had a mean of 47.8 (SD 5.7). PCS was associated with, periodontal status, chronic health condition, self-perceived oral health needs, self-assessed oral health status, oral health impact score and the interaction between gender and level of education [F(11 552) = 10.57; P < 0.0001]. These independent variables accounted for 16% of the variance in PCS. The multivariate model predicting MCS had only one significant variable (self-reported gingival bleeding), explaining 1.5% of the variance. The OHIP-14 ranged from 0 to 48 with a mean score of 5.6 (SD 9.3). The model predicting OHIP-14 contained four significant variables: perceived oral health treatment needs, number of missing natural teeth, reports of having to sip liquid to help swallow food, and gender [F(4576) = 33.39; P < 0.0001], and explained 18% of the variance. The results demonstrated a negative association between oral health indicators and both the oral health-related QOL and the physical component of the SF-12. Conclusion:, The present findings support a growing recognition of the importance of oral health as a mediator of QOL. However, the self-selected sample and modest predictive power of the multivariate models suggest that further research is needed to expand this explanatory model. [source] Applicability of an abbreviated version of the oral impacts on daily performances (OIDP) scale for use among Tanzanian studentsCOMMUNITY DENTISTRY AND ORAL EPIDEMIOLOGY, Issue 1 2003J. R. Masalu Abstract , Objectives: The objective was to examine the applicability of an abbreviated version of the oral impact of daily performances (OIDP) inventory to Tanzanian adults attending the University of Dar es Salaam. Method: A total of 1123 students (mean age 26.4 years, response rate 58%) completed a survey instrument designed to measure subjective oral health indicators including the eight-item OIDP frequency scores. After a period of 4 weeks, 228 students (mean age 24.6 years, response rate 65%) were examined clinically for the presence or absence of oral disorders. Results: A total of 51% of the participants reported that an oral problem had affected them on at least one daily performance in the 6 months preceding the survey. Cronbach's alpha for the OIDP frequency items was 0.83 and 0.87 on the first and second administration of the questionnaire. A reliability coefficient (Spearman's rho) of 0.87 was obtained for the OIDP frequency scores. For five of the eight OIDP frequency items, the kappa values ranged from 0.60 to 1.0, whereas one scale item had the less satisfactory value of 0.22. Construct validity was demonstrated in that the OIDP frequency scores were statistically significantly associated in the expected direction with clinically observed oral problems and a global self-report indicator of oral health status, respectively. Conclusion: The OIDP frequency scale seems to have acceptable psychometric properties in the context of a descriptive questionnaire survey among Tanzanian university students. [source] | ||||||||||
