Obesity is associated with increased mortality. Weight loss improves cardiovascular risk factors, but no prospective interventional studies have reported whether weight loss decreases overall mortality. In fact, many observational studies suggest that weight reduction is associated with increased mortality. The prospective, controlled Swedish Obese...
Article
The aim of this study was to investigate the relative burden of rhinitis and asthma on health-related quality of life (HRQL) as a function of gender and age in the general population. A cross-sectional, general population survey was conducted, comprising 5918 men and women aged 16-64 years. The SF-36 Health Survey was administered by mail, along wi...
Article
We examined psychometric properties and validity of a general (Ways of Coping Questionnaire; WCQ) and a condition-specific (Spinal Cord Lesion-related Coping Strategies Questionnaire; SCL CSQ) measure of coping strategies. The sample included 181 community-residing traumatically spinal cord lesioned persons aged 16 – 85 years. Multi-trait/multi-ite...
Article
Patients with gastric cancer considered amenable to a curative surgical procedure on the basis of a conventional preoperative workup (N=98) answered health-related quality-of-life questionnaires and completed a psychiatrist's interview before the intervention. All patients were blinded to the type of surgical procedure that would ultimately be perf...
Article
Theories of coping and response shift have suggested that emotional adaptation is related to value changes, e.g. a deemphasized importance of lost life values and an enlargement of the scope of values. Perceived attainment and importance of 82 life values were examined in 65 patients with chronic obstructive pulmonary disease (COPD) and related to...
Article
Full-text available
Although the use of appropriate coping strategies has been suggested to be a key factor in determining successful adjustment to severe physical illness/disability, little systematic support for this link has been found. We investigated relationships between spinal cord lesion-related coping strategies and health-related quality of life when studyin...
Article
Weight loss is associated with short-term amelioration and prevention of metabolic and cardiovascular risk, but whether these benefits persist over time is unknown. The prospective, controlled Swedish Obese Subjects Study involved obese subjects who underwent gastric surgery and contemporaneously matched, conventionally treated obese control subjec...
Article
To evaluate the performance of the first non-English (Swedish) SF-36 version 2.0 (V2) regarding scaling assumptions, reliability and validity, with special emphasis on the effects of extending the response scales of the two role functioning scales, role physical (RP) and role emotional (RE), from a dichotomous to a five-step format. Questionnaires...
