  • Health-related quality of life as associated with asthma control, psychological status and insomnia
  • 2022
  • Ingår i: Upsala Journal of Medical Sciences. - Uppsala : Upsala Medical Society. - 0300-9734 .- 2000-1967. ; 127
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Asthma is associated not only with lower health-related quality of life (HRQL) but also with psychological health and insomnia. The aim of this study was to investigate associations between HRQL, asthma symptoms, psychological status and insomnia in adults from three Nordic countries.Methods: This study comprised 2,270 subjects aged 29–55 from Sweden, Iceland and Norway. HRQL was measured with the 36-Item Short Form Health Survey (SF-36). The physical (PCS) and mental health (MCS) component scores were calculated with higher values, indicating better health status. Symptoms of depression and anxiety were measured using the Hospital Anxiety and Depression Scale (HADS). Insomnia was assessed with the Basic Nordic Sleep Questionnaire. An asthma score consisting of a sum of the positive answers to five respiratory symptoms was used in the analysis. Spirometry and allergy tests were also performed.Results: High HADS and sleep disturbance scores were both related to a low PCS and MCS, respectively, after adjusting for confounders. High age and high body mass index (BMI) were associated with low scores on the PCS, whilst the opposite was found for the MCS. A higher asthma score was related to a low PCS. An interaction between the HADS and the asthma symptom score was observed for the PCS (P = 0.0002), where associations between psychological status and the PCS were more pronounced for individuals with more symptoms than for individuals without symptoms.Conclusions: In this study, we found that HRQL of life was independently related to the HADS, insomnia and asthma symptoms. Further prospective studies to identify the most efficient target for intervention in order to improve asthma control are needed.

  • Personality, adherence, asthma control and health-related quality of life in young adult asthmatics
  • 2009
  • Ingår i: Respiratory Medicine. - : Elsevier. - 0954-6111 .- 1532-3064. ; 103:7, s. 1033-1040
  • Tidskriftsartikel (refereegranskat)abstract
    • BackgroundStriving for improved adherence and asthma control is of vital concern in today's asthma management. Several influential factors have been identified, but the importance of personality traits has been insufficiently explored. The aim was first to determine whether personality traits in young adult asthmatics are related to asthma control and health-related quality of life (HRQL), and second to examine the influences of personality traits on adherence to regular asthma medication treatment.MethodsYoung adult asthmatics, 22 years of age (n = 268) completed questionnaires. Statistical analyses were performed.ResultsThe personality traits Negative Affectivity and Impulsivity correlated negatively with asthma control, whereas in women Hedonic Capacity correlated positively with asthma control. Negative Affectivity, Impulsivity, Hedonic Capacity, Alexithymia and asthma control predicted the mental dimension of HRQL. Asthma control and physical activity predicted the physical dimension of HRQL. Among respondents with regular asthma medication (n = 109), Impulsivity correlated negatively with adherence. In men, Antagonism and Alexithymia were associated with low adherence. Additionally, Alexithymia, Hedonic Capacity and Negative Affectivity showed non-linear relationships with adherence, meaning that initially increased scores on these personality traits scales were associated with increased adherence but higher scores did not increase adherence. Respondents who were prescribed a single inhaler combining ICS and LABA reported higher adherence than those with monotherapies.ConclusionThese data suggest that personality can influence how asthma patients adhere to asthma medication treatment, and report their control and HRQL. Tools determining personality traits may be useful in the future in individualizing management of asthma patients.

  • Dietary intake, leisure time activities and obesity among adolescents in Western Sweden: a cross-sectional study
  • 2016
  • Ingår i: Nutrition Journal. - : Springer Science and Business Media LLC. - 1475-2891. ; 15:41
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Overweight and obesity among adolescents are increasing worldwide. Risk factors include dietary intake characteristics and high levels of physical inactivity. In Sweden, few large comprehensive population-based surveys of dietary intake and lifestyle among adolescents have been carried out. Thus, the purpose of the current study was to describe dietary intake and food choices as well as leisure time activities in relation to overweight and obesity in a total sample of all schoolchildren aged 15 years in Western Sweden. Methods: In 2008, a questionnaire was sent to all 21,651 adolescents born in 1992 in Vastra Gotaland Region, Sweden. Participation rate was 54.3 % (50.7 % girls/49.3 % boys). The questionnaire included a 73-item semi-quantitative food frequency questionnaire and questions on lifestyle. Results were evaluated against the Nordic Nutrition Recommendations and Swedish indicators of healthy diet and exercise habits. Associations with concurrent overweight and obesity were evaluated in multiple linear regression analysis. Results: Among girls, 49.5 % reached the goal of consuming fruit and vegetables at least daily, whereas for boys the figure was 34.4 %. Among both sexes, 15 % reached the goal of consuming fish at least twice weekly. Two-thirds of both sexes reached the goal of regular moderate or vigorous physical activity weekly. In total, 12.4 % were overweight and 2.4 % were obese. More girls than boys were underweight, whereas more boys than girls were overweight or obese (p < 0.001). Boys exhibited a more frequent intake of sodas and concentrated fruit juices, milk 3 % fat, bread and potatoes and fast food (p < 0.001). Frequent intake of candies and chocolate was reported by both sexes. Among girls and boys, living in rural areas, living in apartments and reporting no frequent leisure time physical activity were significant risk factors for being overweight or obese, also when adjusted for other risk factors. Conclusions: Dietary habits of adolescents in Western Sweden warrant improvements. Public health actions should be taken to increase consumption of fruit, vegetables and fish, and decrease consumption of sodas and candies and also to increase frequency of physical activity. These actions may be helpful in reducing risks for overweight and obesity.

  • Increased Prevalence of Symptoms of Rhinitis but Not of Asthma between 1990 and 2008 in Swedish Adults : Comparisons of the ECRHS and GA(2)LEN Surveys
  • 2011
  • Ingår i: PLoS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 6:2, s. e16082-
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The increase in asthma prevalence until 1990 has been well described. Thereafter, time trends are poorly known, due to the low number of high quality studies. The preferred method for studying time trends in prevalence is repeated surveys of similar populations. This study aimed to compare the prevalence of asthma symptoms and their major determinants, rhinitis and smoking, in Swedish young adults in 1990 and 2008. Methods: In 1990 the European Community Respiratory Health Survey (ECRHS) studied respiratory symptoms, asthma, rhinitis and smoking in a population-based sample (86% participation) in Sweden. In 2008 the same symptom questions were included in the Global Allergy and Asthma European Network (GA(2)LEN) survey (60% participation). Smoking questions were however differently worded. The regions (Gothenburg, Uppsala, Umea) and age interval (20-44 years) surveyed both in 1990 (n = 8,982) and 2008 (n = 9,156) were analysed. Results: The prevalence of any wheeze last 12 months decreased from 20% to 16% (p<0.001), and the prevalence of "asthma-related symptoms" was unchanged at 7%. However, either having asthma attacks or using asthma medications increased from 6% to 8% (p<0.001), and their major risk factor, rhinitis, increased from 22% to 31%. Past and present smoking decreased. Conclusion: From 1990 to 2008 the prevalence of obstructive airway symptoms common in asthma did not increase in Swedish young adults. This supports the few available international findings suggesting the previous upward trend in asthma has recently reached a plateau. The fact that wheeze did not increase despite the significant increment in rhinitis, may at least in part be due to the decrease in smoking.

  • High IQ in Early Adulthood is Associated with Parkinson´s Disease
  • 2020
  • Ingår i: Journal of Parkinson's Disease. - : IOS Press. - 1877-7171 .- 1877-718X. ; 10:4, s. 1649-1656
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: High education level and high occupational complexity have been implicated as risk factors for Parkinson’s disease (PD). Objective: The objective was to determine whether cognitive capacity, measured as IQ, in early adulthood is associated with the subsequent development of PD. Method: Data on IQ were retrieved from the Swedish Military Service Conscription Registry, comprising Swedish males who enlisted for military service in the period 1968–1993 (N = 1,319,235). After exclusion, 1,189,134 subjects in total were included in the present study. Individuals who later developed PD (N = 1,724) were identified using the Swedish National Patient Register and the Swedish Cause of Death Register. Results: High education level was associated with PD. High IQ was associated with PD (p < 0.0001), both when analyzed as a continuous variable and when divided into three categories. The hazard ratio for the high IQ category compared to the low IQ category was 1.35 (95% confidence interval 1.17–1.55). Strong test results on the subtests, measuring verbal, logic, visuospatial and technical abilities, were also associated with PD. In a subgroup, smoking was inversely associated with PD, as well as with IQ. Conclusions: This study identifies high IQ to be a risk factor for PD.

  • The erythrocyte sedimentation rate in male adolescents and subsequent risk of Parkinson’s disease: an observational study
  • 2021
  • Ingår i: Journal of Neurology. - : Springer Science and Business Media LLC. - 0340-5354 .- 1432-1459. ; 268, s. 1508-1516
  • Tidskriftsartikel (refereegranskat)abstract
    • Systemic inflammation may be implicated in the pathophysiology of Parkinson’s disease (PD). Since PD occurs usually in later life, most studies of causal factors are conducted in older populations, so potentially important influences from early life cannot be adequately captured. We investigated whether the erythrocyte sedimentation rate (ESR) in early adulthood is associated with the subsequent development of PD in men. As part of Swedish national conscription testing conducted from 1968 through 1983 (N = 716,550), the erythrocyte sedimentation rate, as a measure of inflammation, was measured in 659,278 young men. The cohort was observed for subsequent PD events (N = 1513) through December 2016. Cox proportional hazards models were used to estimate the hazard ratios (HR) with 95% CI with adjustment for potential confounders. Individuals with higher ESRs were significantly less likely to be diagnosed with PD, as ESR was linearly and inversely associated with PD risk. The magnitude of the association between ESR and PD risk was similar for increases up to 15 mm/h, leveled off thereafter, and was non-significant for ESR values > 20 mm/h. The HR for PD with basic adjustments (age at conscription, year of conscription, test center and erythrocyte volume fraction) was 0.94 (95% CI 0.89–0.99, P = 0.02) per log2 increase in ESR, corresponding to a two-fold increase in ESR. Further adjustments for potential confounders (parental education, systolic and diastolic blood pressures, and IQ) scarcely altered the HR. The results suggest a prospective association between high ESR and reduced risk for PD.

  • Natural History of Perceived Food Hypersensitivity and IgE Sensitisation to Food Allergens in a Cohort of Adults
  • 2014
  • Ingår i: Plos One. - : Public Library of Science (PLoS). - 1932-6203. ; 9:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: No longitudinal studies exist on the natural history of food hypersensitivity and IgE sensitisation to food allergens in adults. Objective: To examine the natural history of food hypersensitivity, the natural history of IgE sensitisation to food allergens and to investigate the risk factors for new onset food hypersensitivity. Methods: Food hypersensitivity was questionnaire-assessed in 2307 individuals (aged 20-45 years) from Iceland and Sweden during the European Community Respiratory Health Survey both at baseline and follow-up 9 years later. IgE food and aeroallergen sensitisation were assessed in a subgroup of these individuals (n = 807). Values of 0.35 kU/L and above were regarded as positive sensitisation. Results: Food hypersensitivity was reported by 21% of the subjects and this proportion remained unchanged at follow-up (p = 0.58). Fruits, nuts and vegetables were the three most common causes of food hypersensitivity, with a similar prevalence at baseline and follow-up. The prevalence IgE sensitisation to food allergens decreased in general by 56% (p < 0.001) and IgE sensitisation to peanut decreased in particular by 67% (p = 0.003). The prevalence of timothy grass IgE sensitisation decreased by 15% (p = 0.003) while cat, mite and birch IgE sensitisation did not decrease significantly. Female sex, rhinitis, eczema and presence of IgE sensitisation to aeroallergens were independently associated with new onset food hypersensitivity. Conclusion: The prevalence of food hypersensitivity remained unchanged while the prevalence of IgE sensitisation to food allergens decreased in adults over a 9-year follow-up period. The decrease in prevalence of IgE sensitisation to food allergens was considerably larger than the change in prevalence of IgE sensitisation to aeroallergens.

  • How to promote prevention--economic incentives or legal regulations or both?
  • 2003
  • Ingår i: Scand J Work Environ Health. ; 29:3, s. 239-45.
  • Tidskriftsartikel (refereegranskat)abstract
    • Legal regulations of the work environment are probably regarded as the main tools for promoting prevention at the workplace. Legal regulations are expressed as occupational exposure limits, bans, and taxes. Taxes can be regarded as economic incentives as well, and other economic incentives are insurance systems for employers' and consumers' actions. The latter have been found to have profound effects regarding environmental issues and may also, in the future, be a powerful tool for workplace-related prevention. The research in this area is rather limited, but there are some research results that can be obtained from the area of environmental economics. This paper discusses some examples in which legal regulations, economic incentives, or both have been used. Legal regulations and market-based economic incentives may produce similar results, but the economic cost and political feasibility typically differ. This situation makes the selection and design of instruments an important field for future research.
