Substance and tongue-region specific loss in basic taste-quality identification in elderly adults.

Physiological anorexia, decreased dietary variation, and weight loss associated with poor health are common conditions in the elderly population, with changes in chemosensory perception as important contributing causes. The present study of age-related taste loss aimed to investigate the question whether this loss is generalised and unspecific, or whether it exhibits differences in relation to certain tastants and/or differences in the topographical distribution of age-related loss. Impregnated "taste strips" with four concentrations of each of the tastants sucrose, NaCl, quinine-hydrochloride, and citric acid were applied on the tip, midlateral and posteromedial tongue regions to be identified as either sweet, salty, bitter, or sour by 30 young and 26 elderly adults. The results showed more pronounced age-related loss in identification for citric acid and quinine-hydrochloride than for sucrose and NaCl at both the tip and midlateral regions, but not at the posteromedial region where both age groups performed close to chance level. These findings may have implications for food preferences, and thus, the diets of elderly people.

Prevalence of self-reported poor odor detection sensitivity: the Skövde population-based study.

OBJECTIVE: To enable adequate planning of ENT healthcare it is important to know the prevalence of olfactory dysfunction in the general population. Whether an individual will actually seek medical attention for olfactory dysfunction is likely to depend predominantly on his/her self-evaluation of the sense of smell. This motivated an investigation of the prevalences of self-reported poorer- and better-than-normal odor detection sensitivity in the general population. MATERIAL AND METHODS: A random sample of 1900 adult inhabitants, stratified for age and gender, was drawn from the municipal population register of Skövde, Sweden. Subjects were asked to attend a structured interview concerning their self-evaluation of their odor detection sensitivity. RESULTS: In total, 1387 volunteers (73% of the sample) were investigated. The overall prevalences of self-reported poorer- and better-than normal odor detection sensitivity were 15.3% and 17.4%, respectively. The prevalence of poorer sensitivity was found to increase with age, and the prevalence of better sensitivity was lower in men than women. CONCLUSIONS: Considering the fairly high participation rate in this study and the fact that the population of Skövde is representative of the general Swedish population, the obtained prevalences can be considered representative of the general Swedish adult population.

Prevalence of olfactory dysfunction: the skövde population-based study.

OBJECTIVES/HYPOTHESIS: Patients with olfactory dysfunction appear repeatedly in ear, nose, and throat practices, but the prevalence of such problems in the general adult population is not known. Therefore, the objectives were to investigate the prevalence of olfactory dysfunction in an adult Swedish population and to relate dysfunction to age, gender, diabetes mellitus, nasal polyps, and smoking habits. STUDY DESIGN: Cross-sectional, population-based epidemiological study. METHODS: A random sample of 1900 adult inhabitants, who were stratified for age and gender, was drawn from the municipal population register of Skövde, Sweden. Subjects were called to clinical visits that included questions about olfaction, diabetes, and smoking habits. Examination was performed with a smell identification test and nasal endoscopy. RESULTS: In all, 1387 volunteers (73% of the sample) were investigated. The overall prevalence of olfactory dysfunction was 19.1%, composed of 13.3% with hyposmia and 5.8% with anosmia. A logistic regression analysis showed a significant relationship between impaired olfaction and aging, male gender, and nasal polyps, but not diabetes or smoking. In an analysis of a group composed entirely of individuals with anosmia, diabetes mellitus and nasal polyps were found to be risk factors, and gender and smoking were not. CONCLUSION: The sample size of the population-based study was adequate, with a good fit to the entire population, which suggests that it was representative for the Swedish population. Prevalence data for various types of olfactory dysfunction could be given with reasonable precision, and suggested risk factors analyzed. The lack of a statistically significant relationship between olfactory dysfunction and smoking may be controversial.

Consequences of olfactory loss and adopted coping strategies.

UNLABELLED: The aims of this study were to investigate the effects of loss of smell as regards the quality of life and the coping strategies used. METHODS: Seventy-two patients with anosmia (46%) or hyposmia (54%) filled in the validated Multi-Clinic Smell and Taste Questionnaire, the validated General Well-being Schedule (GWBS), and answered other questions shown to be of good validity. RESULTS: Several kinds of negative effects, risks associated with the loss, interference with daily routines and deteriorations in well-being were common. Physical health, financial security, profession, partnership, friendship, emotional stability and leisure were also deemed to be negatively affected and GWBS scores show compromised psychological well-being. The importance of olfaction seemed to be more noticeable after the loss of smell, and several kinds of problem- and emotion-focused coping strategies were adopted by these patients. CONCLUSIONS: We found that the loss of smell had substantial adverse effects on the quality of life and that high priority should be given to its diagnosis and treatment and to further research in this field. Furthermore, a combination of problem- and emotion-focused coping strategies may be suggested to patients who have recently lost the sense of smell.
