Abstract [en]

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 (R). 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 CHA(2)DS(2)VASc 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.

Abstract [en]

Aim: The purpose of the present study is to examine the prevalence of active commuting and factors associated with participation in active commuting in the municipality of Karlskrona, Sweden. Active commuting is defined here as walking or cycling to and from school/work for at least 15 min one-way. Method: A cross-sectional study was carried out, which included baseline data from parents-to-be. Pregnant females and their partners were invited to participate in the study when they contacted either of the municipality’s two antenatal clinics. Data collection ran from March 2008 to February 2009. When completing the questionnaire, the participants were asked to reflect on their situation one month before the female became pregnant. The final sample consisted of 432 participants (response rate 51.9% for females and 85.0% for males). Results: The main mode of commuting was motor vehicle (63.0%), with active commuters forming a minority (8.3%). The main facilitating factor for active commuting was living in an urban as opposed to a rural area. Regular participation in outdoor recreational physical activity was significantly positively associated with active commuting. Being Swedish and being surrounded by a green space environment were significantly negatively associated with active commuting. Conclusions: This study found that the number of people who are active commuters is modest and other modes of transportation are preferred. Several facilitating and impeding factors associated with active commuting were also found, indicating the importance of applying a broad health-promoting approach to encouraging active commuting.

Abstract [en]

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.

Abstract [en]

Background: In order to increase the current levels of physical activity new strategies have been suggested where it is incorporated into daily routines, such as commuting to and from school/work. Active commuting i.e. cycling or walking to and from school/work is an excellent strategy to increase the overall activity levels. Even though the health benefits of active commuting are well documented, non-active modes of transportation (i.e. cars, bus, train) remain the main mode of transportation. The purpose of the present study is to examine the prevalence and what factors are influencing participation in active commuting in the municipality of Karlskrona, Sweden. Method: A cross-sectional study, including base-line data from parents-to- be was carried out, including 432 participants. Questionnaires were filled in and data collection was conducted during a year in 2008 and 2009. The results were calculated using multivariate logistic regression with odds ratios (OR) and 95% confidence interval (CI). Results: The main mode of commuting was motorised vehicle (63.0%), whilst active commuters were a minority (8.3%). The regression model demonstrated a negative association between being Swedish and AC; as such immigrants were more likely to be active commuters (CI 0.08-0.80). The variable mostly associated with AC was the type of residential area. Participants living in an urban area had 5.4 times higher odds of AC compared to participants living in a rural area (CI 1.51-18.54). Being surrounded by a green-space environment decreased the probability of engaging in AC compared to being surrounded by buildings the majority of time (CI 0.07-0.60). Another important variable was outdoor recreational PA, were engaging resulted in 3.9 times higher odds of AC compared to those not engaging in outdoor recreational PA (CI 1.31-11.71). Although the variable pet-ownership remained in the last step of the model non-significant, it explains some of the variance in the model (0.10-1.24). Conclusions: The number of people being active are modest and are instead using other modes of transportation. This study found several factors both facilitating and impeding active commuting, signifying the importance of applying a broad health promotional approach to active commuting.

Abstract [en]

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.

Abstract [en]

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.

Abstract [en]

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.

Abstract [en]

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.
