Knowledge of color perception in old age can be of value when using color contrast, cues and codes in the environment to promote orientation and function. The color naming test indicated that the colors white, black, yellow, red, blue and green promoted recognition to the highest degree among all subjects. A gender-related difference, in favor of women, occurred in naming five of the mixed colors. Women also used more varied color names than men. Color discrimination was easier in the red and yellow area than in the blue and green area. This result correlates positively with visual function on far sight, and negatively with diagnosis of a cataract. The preference order for seven colors put blue, green and red at the top, and brown at the bottom, hence agreeing with earlier studies, and indicating that the preference order for colors remains relatively stable also in old age. This result should be considered when designing environments for old people.</p>","PeriodicalId":76984,"journal":{"name":"Aging (Milan, Italy)","volume":"11 3","pages":"176-85"},"PeriodicalIF":0.0,"publicationDate":"1999-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21340887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bivariate analysis found elevated mortality related to being male, having more than one IADL dysfunction, more than two ADL dysfunctions, financial problems, no social support in times of emergencies, bad self-rated health status, cognitive impairment, confinement to bed during the fortnight prior to interview, and lack of regular exercise. Logistic regression controlling for gender, various clinical diagnoses, financial state, social support and smoking status showed IADL (ROR = 4.57, 95% CI 1.51, 13.90), cognitive impairment (ROR = 3.99, 95% CI 1.85, 8.59) and having been bed-sick a week or more during the preceding fortnight (ROR = 6.60, 95% CI 1.00, 43.86) to be independent predictors of mortality. All persons who had a cognitive problem and were dysfunctional in more than two IADL categories, and 93.8% of persons who had been bed-sick and had more than one IADL dysfunction died during the study period.

The study group was composed of 100 patients who had undergone elective surgery in two orthopedic and two general surgical units. Of the 50 patients in the orthopedic units, 26 had undergone hip arthroplasty and 24 knee arthroplasty: of the 50 patients in the general surgical units, 23 had had breast cancer surgery, and 27 abdominal surgery. The patients were interviewed, using a structured interview format, on three occasions; at the ward on the first and second day after surgery, and by telephone about ten days after discharge from hospital. Within both the sensory and the emotional dimensions, logistic regression analyses showed that the dependent variables of pain and distress were significantly related above all to type of surgery and sense of coherence (SOC). In a cluster analysis, three meaningful clusters of patients were obtained. The patients in the different profiles showed variations in their experiences of pain and distress. The 12 patients with the least favorable scores had weaker SOC than the patients in the other profiles. It is concluded that type of surgery and psychological factors influenced patients' experiences of pain and distress after undergoing surgery. These experiences should be reduced by identifying risk patients, and improving assistance and support in the nursing ward, and also when patients have returned home.</p>","PeriodicalId":76984,"journal":{"name":"Aging (Milan, Italy)","volume":"11 2","pages":"73-82"},"PeriodicalIF":0.0,"publicationDate":"1999-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21252787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This cross-sectional study used Minimum Data Set (MDS) assessments of nursing home residents in 6 US states, Copenhagen, Reykjavik, and selected locations in Italy and Japan. The outcome measures were life expectancy at age 65, population over 65, percentage over 65's in nursing homes, and clinical characteristics of nursing home residents from a multinational database of RAI/MDS assessments. We found that Japan has the highest life expectancy, and the second lowest expenditure on health care. The United States has the highest expenditure on health care and intermediate life expectancy. Italy has the highest proportion of population over 65 and the lowest proportion of over 65's in nursing homes. Iceland, a relatively young country, has the highest proportion of over 65's in nursing homes. Residents in Italy and the United States had the most severe physical, cognitive and clinical characteristics, those in Iceland the least. There was wide variation in markers of quality of care, with no country either uniformly good or bad across multiple measures. In conclusion, headline statistics comparing nations' percentage of Gross Domestic Product (GDP) spent on health care, age structure of the population, percentage of over 65's in nursing homes and clinical characteristics bear no consistent relationship. Local policy and practice also affect quality of care. Standardized assessment enables comparisons at local, national and international levels making possible further research on targeting and the appropriate use of institutional care, thus permitting a range of efficiency measures to be developed to inform policy.</p>","PeriodicalId":76984,"journal":{"name":"Aging (Milan, Italy)","volume":"11 2","pages":"83-9"},"PeriodicalIF":0.0,"publicationDate":"1999-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21253260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
