Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In this thesis the need for physical activity interventions is investigated in a general adult population, the characteristics of physical activity referral (PAR) scheme recipients and referral practitioners, and the effectiveness of PAR in a routine primary health-care (PHC) setting in the county of Östergötland, Sweden. The thesis consists of four papers: three papers are based on a quantitative, uncontrolled prospective PAR study and one paper is based on a population survey in the county of Östergötland, Sweden.In 2006, only one in four of the adult population, aged 18–84 years, in Östergötland was considered sufficiently active to meet the Swedish national public health recommendations, stated as “30 minutes of moderate physical activity a day”. More than one-third (37%) reported that they hade no intentions to change their physical activity levels, while 36% had thought about change, and 27% were determined to change. Although the individuals felt a large responsibility for their own physical activity, they also believed that this responsibility is partly shared by health-care providers. Among those who wanted to increase their physical activity level, almost one in seven of the total population and one in four among those reporting poor general health, with a BMI over 30 and those who were inactive reported that they wanted support to bring about this change. More than half of them wanted this support from their health-care provider.During 2004 and 2005, a total of 6300 patients received PARs as part of the Östergötland PAR scheme. Two-thirds of the patients were female and half of the patients were 45–64 years old. The PAR scheme reached a relatively high proportion of physically inactive people. PARrelated statistics, including the numbers of referrals made at individual PHC centres and by different professional categories, showed large differences in prescribing activities, both by patient categories, and by prescribing professionals, indicating great potential for further improvements of this scheme in the future.Half of the patients (51%) who received PARs were recommended home-based activities, such as walking. Patient follow-up showed that an increase in self-reported physical activity level was achieved by 52% of the patients at the 12-month follow-up. The proportion of inactive patients decreased from 33% at baseline to 20% at 12 months. The proportion of patients who were physically active on a regular basis increased from 22% at baseline to 32% at 12 months. Neither patient age, diagnosis/PAR reason nor the profession of the prescriber were associated with differences in effectiveness. Low activity levels at baseline and homebased activities were significantly associated with increased physical activity at 12 months. Half of the patients (50%) achieved adherence to PARs at the 12-month follow-up, with adherence assessed by simply asking the patients about their adherence to prescribed activity. Patients’ activity levels at baseline (being at least somewhat physically active) and being issued home-based activities were significantly associated with higher adherence at 12 months.

- Presented within this paper are the findings and illustrated experimental results, for the extracting parameters of specific chemical solutions, used to represent the complicated permittivity and the loss tangent of liquids at microwave frequencies. In particular, the endothelial cells growth medium and Dulbecco's Phosphate Buffered Saline (DPBS) solution in the case of the experiment's sample were evaluated in 50 ml water-based solution at a test frequency between 200 MHz and 50 GHz. The vector network analyzer model E8361A was used for measuring complex reflection and permittivity coefficient parameters. From the numerical results, different values of the loss tangent were identified when compared with test samples of plain water in the frequency range of 200 MHz to 10 GHz. Findings obtained produced the same results in the 10 GHz as well as higher frequency ranges. Moreover, the research presents the characteristics, differential measurement results of growth medium used for human endothelial cells and DPBS, two of the most common solutions required for culturing cells in vitro. By enabling to distinguish sample characteristics in response to magnetic resonance, this method has potential to be applied for non-invasive and non-destructive analysis of biological samples in biology and medicine.
