- Aim: To investigate whether the age of first exposure to a high-incidence country like Sweden determines the risk of T1DM in children with an origin in a low incidence region of the world.Methods: Register study in a Swedish study population in the age 6–25 years in three categories of residents with an origin in low incidence regions of T1DM (Eastern Europe, East Asia, South Asia and Latin America); 24 252 international adoptees; 47 986 immigrants and 40 971 Swedish-born with two foreign-born parents and a comparison group of 1 770 092 children with Swedish-born parents. Retrieval of a prescription of insulin during 2006 was used as an indicator of T1DM and analysed with logistic regression.Results: The odds ratios (OR) for T1DM were lower than the Swedish majority population for residents with an origin in the four low incidence regions. Being Swedish-born implied a higher risk for T1DM in the four low incidence study groups compared with the internationally adopted with an OR of 1.68 (CI 1.03–2.73).Conclusions: Being born in Sweden increases the risk for T1DM in children with an origin in low incidence countries. This may imply that exposures in utero or very early infancy are important risk factors for T1DM

Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Objective: To compare clinical status after three years of treatment and socio-demographic conditions at onset in children with diabetes born to immigrant parents with children to Swedish born parents. Design: Observational nationwide population based cohort-study on prospectively recorded registry data.Setting: All children with diabetes in Sweden and their parents between 2000 and 2010.Patients: 879 children with diabetes born to immigrant parents out of a total of 13 415 children, the immigrant cohort. To these we added 2627 children with diabetes of Swedish born parents, matched for gender, age and year of onset, the Swedish cohort.Main outcome: The immigrant children had a higher median HbA1c, 69 mmol/mol (8.5 %), compared to their Swedish peers 62 (7.8 %), p = 0.002, and the 75th percentile of 72 (8.8 %) vs 70 (8.5 %). There was however no difference in frequency of severe events of hypoglycemia or keto-acidosis between the two cohorts (p = 0.258). A linear regression model with HbA1c as dependent variable pointed out insulin units per kg BW as the main reason for inferior metabolic control, OR 11.410, CI 95% 7.418_15.402, p < 0.001.Conclusions: Children with diabetes born to immigrant parents have worse metabolic status three years after disease onset.

- Aim: The aim of the present study was to compare clinical and socio-demographic conditions at the onset of Type1 diabetes in children born to immigrant families and children born to Swedish families, and to assess whether those conditions had an impact on metabolic status.Methods and design: This was an observational nationwide population-based matched cohort study on prospectively recorded registry data of all children with diabetes in Sweden and their families during 2000-2010. Out of a total of 13415 children from the Swedish Childhood Diabetes Registry (SWEDIABKIDS), 879 children born to immigrant parents were collected. To these we added 2627 children with Swedish-born parents, matched for gender, age and year of onset of Type1 diabetes.Results: The proportion of low capillary pH (<7.30) at onset was higher in the immigrant cohort [25.8% vs. 16.4% in the Swedish cohort (P<0.001)]. HbA(1c) was also higher [95mmol/mol (10.8%) vs. 88mmol/mol (10.2%), respectively (P<0.001)]. In a logistic regression model with low pH as the dependent variable, we were unable to reveal any significant association to socio-demographic factors, but the odds ratio for HbA(1c) was 0.983 (95%CI 0.976-0.991) and for plasma glucose was 0.953 (95%CI 0.933-0.973).Conclusion: Children born to immigrant parents have lower capillary pH and higher HbA(1c) at diabetes onset. Immigrant families harbour lower socio-demographic living conditions, but this fact does not seem to influence the inferior metabolic condition at diabetes onset.

- Aim: This study examined the clinical status and socio-demographic conditions of children with type 1 diabetes at baseline and after three years of treatment, comparing those born to immigrant parents and Swedish parents. Methods: This observational nationwide population-based cohort study used prospectively collected registry data from Swediabkids, the National Quality Registry for Paediatric Diabetes in Sweden from 2000 to 2010. Of the 13 415 children with type 1 diabetes, there were 879 born to immigrant parents. We selected three children born to Swedish parents from the same registry for each immigrant child matching them by gender, age and year of diabetes onset (n = 2627; with 10 control children missing probably due to the matching procedure). Results: Immigrant children had a higher median glycated haemoglobin level (HbA1c) than their Swedish peers, but there was no difference in the frequency of hypoglycaemia or ketoacidosis between the two cohorts. A linear regression model with HbA1c as a dependent variable showed that insulin units per kilogram of body weight were the main reason for inferior metabolic control. Conclusion: Children with type 1 diabetes born to immigrant parents had inferior metabolic control three years after disease onset compared to children with Swedish born parents. Social family support and educational coping programmes are needed to improve treatment outcomes in immigrants with diabetes.

Type 1 diabetes in children with non-Swedish background : epidemiology and clinical outcome
- 2014

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Sweden holds third place of diabetes incidence in young people after Finland and Sardinia. One fifth of the population is nowadays of foreign descent. We have a substantial number of immigrants from countries where the risk for T1D is considerably lower. Migration as a natural experiment is a concept to assess the risk for diabetes in offspring of immigrant parents and assess the interaction between genetics (genotype) and the impact of environment (phenotype).Aims: To study the risk of incurring diabetes for children of immigrant parents living in Sweden (I) and further study the risk if the child is born in Sweden or not (II); to specifically study and evaluate if children from East Africa have increased risk to develop T1D (III). To investigate if clinical and sociodemographic status at T1D onset differs between immigrant children compared to their Swedish indigenous peers (IV). Finally to study the clinical outcome and the impact of socio-demographic factors at diabetes onset after three years of treatment (V).Methods: All five studies are observational, nationwide and population based, on prospectively collected data. Statistics mainly by logistic and linear regressions.Results: Parental country of origin is a strong determinant for diabetes in the offspring. Children born to immigrant parents seem to keep their low risk compared to their Swedish peers (I). When adding the factor of being born in Sweden, the pattern changed; there was a significantly (p < 0.001) increased risk for T1D if the child was born in Sweden (II). East Africans have a substantial risk for T1D and especially if the children are born in Sweden (III). Immigrant children and adolescents have worse metabolic start at T1D onset compared to their indigenous Swedish peers (IV). After 3 years of treatment, the immigrant children had a sustained higher median HbA1c, compared to their Swedish peers (V).Conclusions: Genotype and influences during fetal life or early infancy have an important impact for the risk of T1D pointing towards epigenetics playing a substantial role. Children with an origin in East Africa have a high risk of incurring T1D. Immigrant children have worse metabolic start at T1D onset, which sustains after three years of treatment

- Background & aims: Rye consumption has shown beneficial effects on prostate cancer tumors, as indicated by slower initial tumor growth in animal models and lowering of prostate-specific antigen (PSA) in humans. This study evaluated the effects of whole grain/bran rye consumption on low-grade inflammation and endothelial function biomarkers in men with prostate cancer. Methods: Seventeen men with untreated, low-grade prostate cancer consumed 485 g rye whole grain and bran products (RP) per day or refined wheat products with added cellulose (WP) in a randomized crossover design. Fasting blood samples were taken before and after 2, 4, and 6 weeks of treatment. Results: Concentrations of tumor nuclear factor-receptor 2 (TNF-R2), e-selectin, and endostatin were significantly lower after consumption of the RP diet compared with WP (p < 0.05). Cathepsin S concentration was positively correlated to TNF-R2 and endostatin concentrations across all occasions. Strong correlations were consistently found between intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) and between interleukin-6 (IL-6) and interleukin-1 receptor antagonist (IL-1RA). No effect of intervention was found in 92 inflammation-related protein biomarkers measured in a proximity extension assay. Conclusions: RP diet lowered TNF-R2, e-selectin, and endostatin, compared with WP in men with prostate cancer. These effects were accompanied by a reduction in PSA.

- BACKGROUND: The Hvidoere Study Group on Childhood Diabetes has demonstrated persistent differences in metabolic outcomes between pediatric diabetes centers. These differences cannot be accounted for by differences in demographic, medical, or treatment variables. Therefore, we sought to explore whether differences in physical activity or sedentary behavior could explain the variation in metabolic outcomes between centers. METHODS: An observational cross-sectional international study in 21 centers, with demographic and clinical data obtained by questionnaire from participants. Hemoglobin A1c (HbA1c) levels were assayed in one central laboratory. All individuals with diabetes aged 11-18 yr (49.4% female), with duration of diabetes of at least 1 yr, were invited to participate. Individuals completed a self-reported measure of quality of life (Diabetes Quality of Life - Short Form [DQOL-SF]), with well-being and leisure time activity assessed using measures developed by Health Behaviour in School Children WHO Project. RESULTS: Older participants (p < 0.001) and females (p < 0.001) reported less physical activity. Physical activity was associated with positive health perception (p < 0.001) but not with glycemic control, body mass index, frequency of hypoglycemia, or diabetic ketoacidosis. The more time spent on the computer (r = 0.06; p < 0.05) and less time spent doing school homework (r = -0.09; p < 0.001) were associated with higher HbA1c. Between centers, there were significant differences in reported physical activity (p < 0.001) and sedentary behavior (p < 0.001), but these differences did not account for center differences in metabolic control. CONCLUSIONS: Physical activity is strongly associated with psychological well-being but has weak associations with metabolic control. Leisure time activity is associated with individual differences in HbA1c but not with intercenter differences.
