This study explores the relationship between nutritional status and oral health quality of life, the self-efficacy of older inpatients and the correlative factors.
In this study, the convenience sampling method was used to select 307 older inpatients in the southern section of the Renji Hospital affiliated to Shanghai Jiao Tong University School of Medicine from October to December 2020 as the main research participants. A mini nutritional assessment questionnaire was used to assess nutritional status, and the Chinese version of a geriatric oral health assessment index questionnaire was used to determine the oral health quality of life. Self-efficacy was assessed by a general self-efficacy scale questionnaire. Descriptive statistics were used to analyse data using the SPSS 22.0 software. Pearson correlation and multiple linear regression analysis were applied to explore the correlation between variables and factors concerned with nutritional status, respectively.
The results of this study showed that the self-efficacy and oral health quality of life of older inpatients were at a moderate level. Among the patients, 263 had one or more tooth defects, and only 128 had oral restorations or wore dentures. The risk of malnutrition in hospitalised older patients was 37.1%, and the incidence of malnutrition was 13.4%. The risk factors of nutritional status of older patients were age, oral-related quality of life, prealbumin index, self-efficacy, chronic disease, monthly income and tooth defect (P < 0.05).
The incidence of malnutrition and malnutrition risk in hospitalised older patients is relatively high. The main associated factors include age, tooth defect, oral health quality of life, self-efficacy, chronic disease status and monthly income. Therefore, older inpatients, especially those with prosthodontic problems, should carry out nutritional assessments, intervention and graded management as soon as possible to improve their self-efficacy, improve their nutrition and health status and reduce the incidence of a poor prognosis.

OBJECTIVE: The goal of our study was to evaluate the reliability, validity, responsiveness and acceptability of the Mandarin (simplified) Chinese version of the EORTC QLQ-OH45.
METHODS: From October 2017 to February 2018, 393 cancer patients were enrolled from three different hospitals in China. A forward and backward translation was made to develop the Mandarin (simplified) Chinese version of EORTC QLQ-OH15. The QLQ-C30 and QLQ-OH15 questionnaires (which we have assembled and named QLQ-OH45 in this paper) were self-administered. Results were statistically analysed using SPSS 21.0. The reliability and validity tests of the questionnaires were assessed by Cronbach\'s α coefficient, Pearson correlation test and Mann-Whitney U tests. Responsiveness to change was measured in an independent sample of patients with head and neck cancer undergoing surgery or radiotherapy or chemotherapy.
RESULTS: An acceptable internal consistency reliability for most multiple-item scales was demonstrated, as Cronbach\'s α coefficients were greater than 0.7 for most multiple-item scales, excepting for cognitive functioning (0.36) and oral health-related QoL functioning (0.55). All domain\'s test-retest reliability coefficients (r) was higher than 0.8. Multi-trait scaling analysis showed good convergent and discriminant validity. A difference in the quality of life (QoL) between older (≥65 years) and younger (<65 years) groups of patients was showed by the known-group comparisons. Low correlations were found between the scales of the QLQ-OH15 and QLQ-C30 in all areas.
CONCLUSIONS: The Mandarin (simplified) Chinese version of QLQ-OH45 demonstrates satisfactory psychometric properties and can be used to measure the oral health-related QoL (OHRQoL) for Chinese cancer patients.
