- Objectives: This paper investigated factors associated with internet usage in the Swedish older adults ranging in age from 60 to 96. Personality traits and individual characteristics have been previously noted to influence internet usage, where older adults have not been the focus population. In this study the relationships between personality, individual characteristics and internet usage were investigated. Methods: A descriptive analysis of the personality tests of a total of 1402 subjects included in the Swedish National Study on Aging and Care (SNAC) was conducted. Three variables were controlled for: sex, age and education. Descriptive statistics, Mann-Whitney and Kruskal-Wallis tests, chi square tests and a logistic regression were used in order to detect the relationships with internet usage. Results: Men differ significantly from women in the personality traits analysis. Those with higher education were more open and neuroticism was lower in the oldest older adults. Internet usage declined significantly with age and those with middle to higher education were using the internet the most. No other associations with internet use were found Conclusion: Personality traits and individual characteristics do not seem to influence the Swedish older adult and their internet usage. What one needs to account for is the age and education of the person. The more educated and the youngest cohorts were using the internet more frequently.

- The increased reliance on Internet use in social functions has presumably left out a part of the population: the oldest-older adults. These are people who have not kept themselves up to date with the technological developments for various reasons. There are, however, exceptions from whom we have something to learn. This study investigates the older people in Sweden who started to use the Internet over a period of 6 years. Cognition, extraversion, openness, functional disability, household economy, sex, age and education were investigated in relation to starting to use the Internet. A chi-square test, Spearman correlation and a logistic regression analysis were conducted. It was found that higher cognition, being male and being between the ages of 60 and 80 years were determining factors in starting to use the Internet for the Swedish older adult. Our results indicate that the oldest-older adults are slow to adapt to using the Internet and more attention should be paid on how to support this group.

Factors influencing Internet usage in older adults (65 years and above) living in rural and urban Sweden
- 2015

Ingår i: Health Informatics Journal. - : Sage Publications. - 1460-4582 .- 1741-2811. ; 21:3, s. 237-249

Tidskriftsartikel (refereegranskat)abstract
- Older adults living in rural and urban areas have shown to distinguish themselves in technology adoption; a clearer profile of their Internet use is important in order to provide better technological and health-care solutions. Older adults' Internet use was investigated across large to midsize cities and rural Sweden. The sample consisted of 7181 older adults ranging from 59 to 100 years old. Internet use was investigated with age, education, gender, household economy, cognition, living alone/or with someone and rural/urban living. Logistic regression was used. Those living in rural areas used the Internet less than their urban counterparts. Being younger and higher educated influenced Internet use; for older urban adults, these factors as well as living with someone and having good cognitive functioning were influential. Solutions are needed to avoid the exclusion of some older adults by a society that is today being shaped by the Internet.

Comorbidity and Sex-Related Differences in Mortality in Oxygen-Dependent Chronic Obstructive Pulmonary Disease
- 2012
-
Ingår i: PLOS ONE. - : Public Library of Science. - 1932-6203. ; 7:4

Tidskriftsartikel (refereegranskat)abstract
- Background: It is not known why survival differs between men and women in oxygen-dependent chronic obstructive pulmonary disease (COPD). The present study evaluates differences in comorbidity between men and women, and tests the hypothesis that comorbidity contributes to sex-related differences in mortality in oxygen-dependent COPD. Methods: National prospective study of patients aged 50 years or older, starting long-term oxygen therapy (LTOT) for COPD in Sweden between 1992 and 2008. Comorbidities were obtained from the Swedish Hospital Discharge Register. Sex-related differences in comorbidity were estimated using logistic regression, adjusting for age, smoking status and year of inclusion. The effect of comorbidity on overall mortality and the interaction between comorbidity and sex were evaluated using Cox regression, adjusting for age, sex, Pa-O2 breathing air, FEV1, smoking history and year of inclusion. Results: In total, 8,712 patients (55% women) were included and 6,729 patients died during the study period. No patient was lost to follow-up. Compared with women, men had significantly more arrhythmia, cancer, ischemic heart disease and renal failure, and less hypertension, mental disorders, osteoporosis and rheumatoid arthritis (P<0.05 for all odds ratios). Comorbidity was an independent predictor of mortality, and the effect was similar for the sexes. Women had lower mortality, which remained unchanged even after adjusting for comorbidity; hazard ratio 0.73 (95% confidence interval, 0.68-0.77; P<0.001). Conclusions: Comorbidity is different in men and women, but does not explain the sex-related difference in mortality in oxygen-dependent COPD.

- Approximate symmetries and conservation laws for deterministic and stochastic differential equations with a small parameter are discussed in detail. Determining equations for infinitesimal approximate symmetries of Ito and Stratanovich dynamical systems are derived. It is shown how to derive conserved quantities for stochastic dynamical systems using their approximate symmetries without recourse to Noether's theorem

Prevalence of unknown and untreated arrhythmias in an older outpatient population screened by wireless long-term recording ECG
- 2016
-
Ingår i: Clinical Interventions in Aging. - 1176-9092 .- 1178-1998. ; 11, s. 1083-1090
-
Tidskriftsartikel (refereegranskat)abstract
- Purpose: With longer life expectancies, the prevalence of arrhythmias is increasing; thus, there is a need for new methods to screen the older outpatient population. This population-based study describes the prevalence of arrhythmias in 200 outpatients aged ≥66 years. We also investigated the feasibility of wireless long-term recording (LTR) using the ECG-BodyKom®. Methods: Two hundred elderly persons aged 66–93 years were recruited from the Swedish National Study on Aging and Care in 2010–2013, and data were collected via wireless LTR ECG-BodyKom. Results: Screening with the LTR ECG revealed that persistent atrial fibrillation (AF) occurred in 10% of the outpatient population aged ≥66 years. Paroxysmal AF occurred in 5.5% of the population, with no difference between younger (60–80 years) and older (≥80 years) elderly participants. Furthermore, all patients with paroxysmal AF had a CHA2DS2VASc score of ≥2 and were therefore potential candidates for follow-up and medical examination. LTR ECG-BodyKom can be considered a feasible method to screen for arrhythmias in older outpatient populations. This simple method requires little of the user, and there was high satisfaction with the equipment and a good overall experience wearing it. Conclusion: The increasing occurrence of arrhythmias in the older population, as well as the high number of untreated cases of arrhythmias such as persistent AF and paroxysmal AF, poses a challenge for health care. Therefore, it is essential to develop effective strategies for their prevention and treatment.

The Choquet and Sugeno Integrals as Measures of Total Effectiveness of Medicines
- 2007
-
Konferensbidrag (refereegranskat)abstract
- The concepts of the Choquet and Sugeno integrals, based on a fuzzy measure, can be adopted as useful tools in estimation of the total effectiveness of a drug when appreciating its positive influence on a collection of symptoms typical of a considered diagnosis. The expected effectiveness of the medicine is evaluated by a physician as a verbal expression for each distinct symptom. By converting the words at first to fuzzy sets and then numbers we can regard the effectiveness structures as measures in the Choquet and Sugeno problem formu-lations. After comparing the quantities of total effectiveness among medicines, expressed as the values of the Choquet or Sugeno integrals, we accomplish the selection of the most efficacious drug.
