- Rationale: To allow for interdisciplinary research on the relations between socioeconomic conditions and health in the ageing population, a new anonymized longitudinal database - the Linnaeus Database - has been developed at the Centre for Population Studies at Umea University. This paper presents the database and its research potential. Design: Using the Swedish personal numbers the researchers have, in collaboration with Statistics Sweden and the National Board for Health and Welfare, linked individual records from Swedish register data on death causes, hospitalization and various socioeconomic conditions with two databases - Betula and VIP (Vasterbottens Intervention Programme) - previously developed by the researchers at Umea University. Whereas Betula includes rich information about e. g. cognitive functions, VIP contains information about e. g. lifestyle and health indicators. Population and sample size: The Linnaeus Database includes annually updated socioeconomic information from Statistics Sweden registers for all registered residents of Sweden for the period 1990 to 2006, in total 12,066,478. The information from the Betula includes 4,500 participants from the city of Umea and VIP includes data for almost 90,000 participants. Both datasets include cross-sectional as well as longitudinal information. Potential: Due to the coverage and rich information, the Linnaeus Database allows for a variety of longitudinal studies on the relations between, for instance, socioeconomic conditions, health, lifestyle, cognition, family networks, migration and working conditions in ageing cohorts. Conclusions: By joining various datasets developed in different disciplinary traditions new possibilities for interdisciplinary research on ageing emerge.

- AIMS: To investigate the impact of development in sleep continuity on transition to and from obesity over time. METHOD: The study used self-reported sleep and body mass index (BMI) measures from the 1965, 1974, 1983, and 1994 waves of the longitudinal Alameda County Study. Sleep continuity was assessed by a question on whether the participants had any troubles falling or staying asleep. Change in sleep and BMI were estimated from the sleep and BMI questions in 1965 and 1994 respectively. Multinomial regression analyses were used to examine the risk/chance for a transition to and from obesity (BMI >or=30 kg/m(2)) due to development in sleep continuity. RESULTS: After adjustment for confounding variables, consistent sleep discontinuity both increases the risk for a transition to obesity and reduces the chance of losing weight, whereas impaired sleep continuity lowers the chance for weight loss. Effects for obesity were non-significant for those with improved sleep continuity. CONCLUSIONS: Consistent sleep discontinuity and impaired sleep continuity increases the risk of transition to obesity or of remaining obese.

How do children experience participating in a coeliac disease screening? A qualitative study based on childrens written narratives

Tidskriftsartikel (refereegranskat)abstract
- Aim: To explore how 12-year-old Swedish children experienced being involved in a coeliac disease (CD) screening. Methods: A qualitative approach was used to analyse short narratives written by children who had taken part in a school-based CD screening. Narratives were written after blood sampling, but prior to learning of the test results. Through an oscillation between the texts, codes, subcategories and four categories, a theme was generated describing the childrens experience. Results: The theme "A Journey towards Confidence" captures the overall experience of the screening. It illustrates that, although some children faced fear or anxiety, overall they had or were provided tools allowing them to cope well and experience a journey towards confidence. The categories describe conditions that contributed to the experience. The first, being involved, reflects the importance of involvement in receiving information and deciding to participate. Being a "good citizen" refers to feeling a duty to help and a trust to be treated fairly. Being able to cope with the screening was influenced by the childrens ability to manage sensations and support received. The last category, being able to balance risk, illustrates that the children were able to balance the risks of screening when they had a realistic understanding of the disease and their vulnerability and had tamed their anxiety. Conclusions: This study increases the understanding of how 12-year-old Swedish children experienced participating in a CD screening and describes conditions important for a positive experience. We show that, although some children faced anxiety, they had, or were provided with, tools allowing them to cope well and gain confidence.

Dermatology in public health - a model for surveillance of common skin diseases
- 2010

Tidskriftsartikel (refereegranskat)abstract
- Aims: The aim was to establish a baseline prevalence of skin conditions of public health importance in the general population and taking the validity of the questions into account. Our model is intended for future surveillance of skin conditions. Methods: The suggested questions have for the first time been used in Swedish population surveys. A random sample was taken from the general population aged 16 to 84 years of the participating areas. Results: During the past 12 months, hand eczema was reported by 9.4%, childhood eczema by 15.7% and nickel allergy by 13.7% of the population. Hand and childhood eczema questions have previously been validated. Taking the validity into account, the actual population prevalence of hand eczema (11.7%) is underestimated, and the prevalence of atopic childhood eczema (10.0%) is overestimated based on the results of the questionnaire. In addition to presenting prevalence, population survey results can be used for risk analyses. A 10-fold risk of hand eczema in individuals with childhood eczema and self-reported nickel sensitivity is shown in our study. Conclusions: Questionnaires can be used for epidemiologic surveillance so long as the questions are validated and that the validity is taken into account when estimating the occurrence of the conditions. Public health surveys such as this one lay the basis for future epidemiological surveillance of skin conditions that can be subject to interventions. We propose that these, or similar, questions should be used regularly in population surveys and supplemented by questions on skin exposure.
