Background and Aims: Self-reported data and/or medical records are often used to assess the prevalence of illness and impairment in epidemiological studies. However, these two data sources do not always provide the same information. The aim was to compare data from interviews and medical records regarding illness, symptoms and impairment in the elderly, and to analyze the agreement between a consensus from both data sources and data from interviews and medical records, respectively., Methods: We interviewed 130 persons (age range 67-99) regarding socio-demographic background data and physical and mental health. Medical records were reviewed. Illness burden was rated according to the Cumulative Illness Rating Scale for Geriatrics, and was rated in three ways based on: (1) interview data; (2) medical records; (3) information from both interviews and medical records considered to be consensus. Agreement was measured by the Kappa coefficient and the Svensson Paired Rank Measurement. A permutation test tested whether the ratings from interviews and medical records had the same agreement when compared with consensus., Results: Statistically significant differences in agreement were found between interview versus consensus and medical records versus consensus for the vascular system (medical records best), eyes/ears/nose/throat/larynx and musculoskeletal/integument (interview best). Medical records gave better in formation concerning specific diseases and diagnoses, whereas interview data provided a better measure of illness, functional impairment and health in a broader sense., Conclusions: Both medical records and interviews yield good information of elderly people's health status, but they focus on different aspects of health.

Background and Aims: Whether or not there has been a "compression of morbidity" in older ages has been vividly debated during the last decades. Previous studies have found indications of both improved and deteriorated health among elderly persons. Few studies have analyzed how changes in health indicators are influenced by social background factors. The aim of this study was to analyze the differences in morbidity--measured as self-assessed health, number of symptoms, number of diseases and physical function--in three different cohorts of 70-year olds, with special regard to the impact of social factors., Methods: We used data from random samples of 70-year-old people born in 1901/02 (cohort 1), 1906/07 (cohort 2), and 1911/12 (cohort 3). In the three cohorts there were 973, 1036 and 619 participants, respectively. They had a medical examination and were interviewed regarding social background, social network, self-assessed health, need of care, and number of diseases., Results: There were fewer 70-year olds not feeling healthy in the two younger cohorts (OR = 0.68; CI = 0.56-0.83, and OR = 0.67; CI = 0.53-0.84 respectively) and fewer with many symptoms. There were also indications of better physical functioning in the younger cohorts. Women seemed to have gained more than men, while the institutionalized persons had a deterioration., Conclusions: There are indications of good years being added, but not for the institutionalized persons.
