- Background/Aims: Growth hormone (GH) treatment regimens do not account for the pubertal increase in endogenous GH secretion. This study assessed whether increasing the GH dose and/or frequency of administration improves pubertal height gain and adult height (AH) in children with low GH secretion during stimulation tests, i. e. idiopathic isolated GH deficiency.Methods: A multicenter, randomized, clinical trial (No. 88-177) followed 111 children (96 boys) at study start from onset of puberty to AH who had received GH(33) mu g/kg/day for >= 1 year. They were randomized to receive 67 mu g/kg/day (GH(67)) given as one (GH(67x1); n = 35) or two daily injections (GH(33x2); n = 36), or to remain on a single 33 mu g/kg/day dose (GH(33x1); n = 40). Growth was assessed as height SDS gain for prepubertal, pubertal and total periods, as well as AH SDS versus the population and the midparental height.Results: Pubertal height SDS gain was greater for patients receiving a high dose (GH(67), 0.73) than a low dose (GH(33x1), 0.41, p < 0.05). AH(SDS) was greater on GH(67) (GH(67x1), -0.84; GH(33x2), -0.83) than GH(33) (-1.25, p < 0.05), and height SDS gain was greater on GH(67) than GH(33) (2.04 and 1.56, respectively; p < 0.01). All groups reached their target height SDS.Conclusion: Pubertal height SDS gain and AH SDS were dose dependent, with greater growth being observed for the GH(67) than the GH(33) randomization group; however, there were no differences between the once-and twice-daily GH(67) regimens.

Tidskriftsartikel (refereegranskat)abstract
- CONTEXT: Studies on clinical and immunological features of Autoimmune Addison's disease (AAD) are needed to understand the disease burden and increased mortality.OBJECTIVE: To provide upgraded data on autoimmune comorbidities, replacement therapy, autoantibody profiles and cardiovascular risk factors.DESIGN, SETTING AND PARTICIPANTS: Cross sectional, population-based study. 660 AAD patients were included utilizing the Swedish Addison Registry (SAR) 2008-2014. When analyzing cardiovascular risk factors, 3,594 individuals from the population-based survey in Northern Sweden, MONICA (MONItoring of Trends and Determinants of CArdiovascular Disease), served as controls.MAIN OUTCOME MEASURE: Prevalence of autoimmune comorbidities and cardiovascular risk factors. Autoantibodies against 13 autoantigens were determined.RESULTS: Sixty percent of the SAR cohort consisted of females. Mean age at diagnosis was significantly higher for females than for males (36.8 vs. 31.1 years). The proportion of 21-hydroxylase autoantibody positive patients was 83% and 62% of patients had one or more associated autoimmune diseases, more frequently coexisting in females (p<0.0001). AAD patients had lower BMI (p<0.0001) and prevalence of hypertension (p=0.027) compared with controls. Conventional hydrocortisone tablets were used by 89% of patients; with the mean dose 28.1±8.5 mg/day. The mean hydrocortisone equivalent dose normalized to body surface was 14.8±4.4 mg/m(2)/day. Higher hydrocortisone equivalent dose was associated with higher incidence of hypertension (p=0.046).CONCLUSIONS: Careful monitoring of AAD patients is warranted to detect associated autoimmune diseases. Contemporary Swedish AAD patients do not have increased prevalence of overweight, hypertension, T2DM or hyperlipidemia. However, high glucocorticoid replacement doses may be a risk factor for hypertension.

- The aim of this study was to compare the frequency of human leukocyte antigen (HLA) genotypes in 1-18-year-old patients with type 1 diabetes newly diagnosed in 1986-1987 (n = 430), 1996-2000 (n = 342) and in 2003-2005 (n = 171). We tested the hypothesis that the HLA DQ genotype distribution changes over time. Swedish type 1 diabetes patients and controls were typed for HLA using polymerase chain reaction amplification and allele specific probes for DQ A1* and B1* alleles. The most common type 1 diabetes HLA DQA1*-B1*genotype 0501-0201/0301-0302 was 36% (153/430) in 1986-1987 and 37% (127/342) in 1996-2000, but decreased to 19% (33/171) in 2003-2005 (P \ 0.0001). The 0501-0201/0501-0201 genotype increased from 1% in 1986-1987 to 7% in 1996-2000 (P = 0.0047) and to 5% in 2003-2005 (P > 0.05). This study in 1-18-year-old Swedish type 1 diabetes patients supports the notion that there is a temporal change in HLA risk.

Adipocytokines in placenta and cord blood in relation to maternal obesity, and foetal and postnatal growth of the child
- 2015

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Background: The nutritional and hormonal state in utero may be a link between maternal obesity and obesity in the offspring. The gene expression in placentae in pregnancies complicated by diabetes is reduced for leptin, but increased for ghrelin. It is not known whether these genes’ expressions in placentae are altered in maternal obesity.Objectives and hypotheses: To compare obese and normal-weight women and their children concerning gene expressions of leptin and ghrelin in placentae; leptin, ghrelin, adiponectin, and C-peptide levels in cord blood, birth size and postnatal growth. Changes in the expression of these adipocytokines may lead to an altered hypothalamic sensitivity to leptin and ghrelin resulting in an increased risk of obesity in the offspring.Method: 32 women with pre-pregnancy obesity, but otherwise healthy, were compared to 32 matched, normal-weight controls. Full-term placenta biopsies were analysed with qPCR for leptin mRNA and ghrelin mRNA. Cord blood samples were examined with ELISA for leptin, ghrelin, adiponectin, and C-peptide concentrations. Birth size and postnatal growth of the children were collected from clinical registers at the Child Health Care Units.Results: The leptin and ghrelin gene expressions in placentae did not differ between obese and normal-weight women. The leptin concentration in cord blood was higher in children of obese mothers (P=0.021). It correlated with birth weight Z-score (r=0.467, P<0.001) and C-peptide level in cord blood (r=0.446, P<0.001). Children of obese women were slightly heavier at birth, but postnatal growth did not differ between groups. Children with birth weight ≤−0.67 Z-score had higher ghrelin levels in cord blood than heavier children (P=0.042). The leptin level in cord blood correlated negatively with weight gain at 6 months (r=−0.332, P=0.009). The ghrelin level in cord blood correlated with weight gain at 3 months in girls (r=0.611, P=0.001), but not in boys. The adiponectin level in cord blood correlated negatively with length gain at 3 years in the obese group (r=−0.571, P=0.033), but not in the normal-weight group.Conclusion: Leptin and ghrelin placental gene expressions are not altered in obese women, but foetal adipocytokine production may influence early postnatal growth, possibly by influencing hunger signalling or insulin levels

Gene expression of inflammatory markers and growth factors in placenta in relation to maternal obesity and foetal and postnatal growth
- 2020
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Maternal obesity is a growing health problem, that contributes to obstetrical complications in pregnancy, as well as neonatal morbidity and mortality. The placenta serves for gas and nutrient exchange between the mother and the foetus, and obesity may influence and modify placental growth and function. The aims of this thesis were to investigate associations between maternal obesity without associated morbidity and gene expression of inflammatory markers and growth factors in the placenta, as well as offspring birth weight and postnatal growth. Study I and III were designed as matched case-control studies including 32 obese women with an early pregnancy body mass index (BMI) ≥ 35.0 kg/m2, study II was an experimental study examining twelve placentas of normal weight women, and study IV was a cohort study including 109 obese women with a BMI ≥ 34.5 kg/m2. In studies I-IV analyses of gene expression were performed and in study III additionally cord blood concentrations were determined. No difference was found in the occurrence of placental gene expression of inflammatory markers or growth factors between obese and normal weight women, nor did the sampling site in placentas of normal weight women influence gene expression of these markers, except for leptin gene (LEP) and insulin receptor gene (INSR) expression. Ghrelin gene (GHRL) and LEP expression, as well as cord blood ghrelin and adiponectin levels, was not altered in maternal obesity, and a negatively U-shaped relationship between LEP expression and infant birth weight (BW) z-scores was observed in the placentas of obese women.In conclusion, no statistically significant difference in gene expressions of inflammatory markers and growth factors in the placenta between severely obese and normal weight women was found. These results are in contrast with earlier studies and could be due to the fact that we examined mainly healthy obese women. The correlations we found between gene expression of leptin in the placenta and the birth weight of the infants warrants further studies.

- Objective: To survey the placental gene expression of inflammatory markers and growth factors in non-smoking obese women with an uncomplicated pregnancy without associated morbidity and delivery at term compared with normal weight women.Methods: Placental tissue samples from 32 obese women (body mass index, BMI >= 35.0 kg/m(2)) were compared with samples from 94 normal weight women (BMI 18.5-25.0 kg/m(2)) matched for age (+/- 1 year), gestational age (+/- 3 days), parity and mode of delivery. Semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) was used to analyse toll receptor-2 and -4, interleukin-6 and -8, tumour necrosis factor-alpha, leptin, adiponectin, insulin-like growth factor-1 and -2, hepatocyte growth factor, hepatocyte growth factor receptor and insulin receptor.Results: There was no significant difference in gene expression in placental tissue samples from obese and normal weight women.Conclusion: We found no difference in the occurrence of inflammatory marker and growth factor mRNA levels in placental tissue samples from a large group of obese women without associated morbidity and with healthy infants compared to a closely matched control group of healthy normal weight women. Compared with the previous studies, this anomalous finding may be explained by the absence of associated morbidity in the obese women in our study.

- PURPOSE: The purpose of this study is to investigate placental ghrelin and leptin expression as well as cord blood ghrelin and adiponectin levels in maternal obesity and associations between placental ghrelin expression, cord blood ghrelin levels and maternal and infant variables.MATERIALS AND METHODS: Placental ghrelin and leptin expression were analyzed by RT-PCR in 32 severely obese and 32 matched normal-weight women. Cord blood ghrelin, adiponectin, leptin, and C-peptide concentrations were analyzed by ELISA.RESULTS: Neither ghrelin nor leptin expression and neither cord blood ghrelin nor adiponectin levels differed between the groups. Placental ghrelin expression was associated with BMI at delivery in the obese women (r = 0.424, p = .016) and in the infants born to normal-weight women with their weight z-scores at six (r = -0.642, p = .010), nine (r = -0.441, p = .015), and 12 months of age (r = -0.402, p = .028).CONCLUSIONS: Placental ghrelin and leptin expression as well as cord blood ghrelin and adiponectin levels do not seem to be altered in severe maternal obesity. Placenta-derived ghrelin may influence the infants' postnatal weight gain, but possibly only when the mother has normal weight.

- Aims: To evaluate the associations between physical activity (PA) and metabolic control, measured by glycated hemoglobin (HbA1c), in a large group of children and adolescents with type 1 diabetes.Methods: Cross-sectional analysis of data from 4655 patients, comparing HbA1c values with levels of physical activity. The data for the children and adolescents were obtained from the Swedish pediatric diabetes quality registry, SWEDIABKIDS. The patients were 7-18 years of age, had type 1 diabetes and were not in remission. Patients were grouped into five groups by frequency of PA.Results: Mean HbA1c level was higher in the least physically active groups (PA0: 8.8% +/- 1.5 (72 +/- 16 mmol/mol)) than in the most physically active groups (PA4: 7.7% +/- 1.0 (60 +/- 11 mmol/mol)) (p < 0.001). An inverse dose-response association was found between PA and HbA1c (beta: -0.30, 95%CI: -0.34 to -0.26, p < 0.001). This association was found in both sexes and all age groups, apart from girls aged 7-10 years. Multiple regression analysis revealed that the relationship remained significant (beta: -0.21, 95% CI: -0.25 to -0.18, p < 0.001) when adjusted for possible confounding factors.Conclusions: Physical activity seems to influence HbA1c levels in children and adolescents with type 1 diabetes. In clinical practice these patients should be recommended daily physical activity as a part of their treatment.

- BACKGROUND: Differences in energy metabolism and physical activity (PA) may contribute to the long-term regulation of body weight (BW).OBJECTIVE: To examine the associations between metabolic determinants, energy expenditure and objectively measured components of PA with change in BW and fat mass (FM). DESIGN: Prospective (4 years.), case-control study in obese (n=13) and normal weight (n=15) young adults.MEASUREMENTS: At baseline, we measured resting metabolic rate, substrate oxidation, movement economy (ml O(2) kg(-1) min(-1)), aerobic fitness (VO(2max)), total and PA energy expenditure by doubly labelled water, and PA by accelerometry. Fat mass was measured by DXA. At follow-up we repeated our measurements of PA and FM.RESULTS: Fat mass increased significantly (P<0.001) in both groups. Physical activity did not change between baseline and 'follow up'. Change in overall PA (counts per minute) was inversely associated with change in BW and (beta=-0.0124, P=0.054) and FM (beta=-0.008, P=0.04). Post hoc analyses suggested that this association was explained by changes in the normal weight group only (beta=-0.01; P=0.008; and beta=-0.0097; P=0.009, for BW and FM, respectively). Metabolic determinants, energy expenditure estimates and subcomponents of PA (i.e. time spent at different intensity levels) were not significantly associated with change in BW or FM.CONCLUSION: Our results suggest an independent association between PA and FM. However, this association may differ depending on obesity status. The gain in FM, without any change in PA, may suggest that dietary intake is the major contributor to the positive energy balance.

- BACKGROUND: The influence of physical activity on body weight in children and adolescents is controversial.OBJECTIVE: The objective was to test the hypothesis that the intensity and duration of physical activity differ between obese and normal-weight adolescents, with no difference in estimated energy expenditure.DESIGN: We compared physical activity in 18 (8 males, 10 females) obese [body mass index (in kg/m(2)) > 30] adolescents (14-19 y) with that in a matched, normal-weight (BMI < 27) control group. Total energy expenditure (TEE) was measured with the doubly labeled water method, and physical activity was measured simultaneously by accelerometry. The physical activity level was determined as the ratio of TEE to the resting metabolic rate (RMR) and activity energy expenditure as 0.9 TEE minus RMR. Accelerometry data included total physical activity (counts x min(-1) x d(-1)), accumulated and continuous duration of activity, and continuous 10-min periods of physical activity of moderate intensity.RESULTS: There was no significant difference in adjusted (analysis of covariance) TEE, RMR, or AEE between groups. The physical activity level was significantly lower (P < 0.05) in the obese group. No sex x group interaction was observed. Differences in total physical activity (P < 0.001), accumulated time (P < 0.05), continuous time (P < 0.01), and continuous 10-min periods of physical activity of moderate intensity (P < 0.01) were observed between groups.CONCLUSIONS: Obese adolescents are less physically active than are normal-weight adolescents, but physical activity-related energy expenditure is not significantly different between groups. The data suggest that physical activity is not necessarily equivalent to the energy costs of activity.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: A randomized multicenter study was conducted in the Stockholm-orebro areas in Sweden to evaluate how treatment aiming at normoglycemia affects fetal growth, pregnancy and neonatal outcome in pregnant women with severe hyperglycemia.Material and methods: Pregnant women with hyperglycemia defined as fasting capillary plasma glucose <7.0 mmol/L and a two-hour plasma glucose value 10.0 and <12.2 mmol/L following a 75-g oral glucose tolerance test (OGTT) diagnosed before 34 weeks of gestation were randomized to treatment (n=33) or controls (n=36). Women assigned to the control group were blinded for the OGTT results and received routine care. The therapeutic goal was fasting plasma glucose 4-5 mmol/L, and <6.5 mmol/L after a meal. Primary outcomes were size at birth and number of large-for-gestational age (>90th percentile) neonates. Secondary outcomes were pregnancy complications, neonatal morbidity and glycemic control.Results: The planned number of participating women was not reached. There was a significantly reduced rate of large-for-gestational age neonates, 21 vs. 47%, P<0.05. Group differences in pregnancy complications and neonatal morbidity were not detected because of limited statistical power. In total, 66.7% of the women in the intervention group received insulin. Of all measured plasma glucose values, 64.1% were in the target range, 7.2% in the hypoglycemic range and 28.7% above target values. There were no cases of severe hypoglycemia.Conclusions: Aiming for normalized glycemia in a pregnancy complicated by severe hyperglycemia reduces fetal growth but is associated with an increased rate of mild hypoglycemia.

- AIMS: The relation of disease progression and age, serum interleukin 10 (IL-10) and interferon gamma (IFNγ) and their genetic correlates were studied in paediatric patients with newly diagnosed Type 1 diabetes.METHODS: Two hundred and twenty-seven patients from the Hvidoere Study Group were classified in four different progression groups as assessed by change in stimulated C-peptide from 1 to 6 months. CA repeat variants of the IL-10 and IFNγ gene were genotyped and serum levels of IL-10 and IFNγ were measured at 1, 6 and 12 months.RESULTS: IL-10 decreased (P < 0.001) by 7.7% (1 month), 10.4% (6 months) and 8.6% (12 months) per year increase in age of child, while a twofold higher C-peptide concentration at 1 month (p = 0.06), 6 months (P = 0.0003) and 12 months (P = 0.02) was associated with 9.7%, 18.6% and 9.7% lower IL-10 levels, independent of each other. IL-10 concentrations did not associate with the disease progression groups. By contrast, IFNγ concentrations differed between the four progression groups at 6 and 12 months (P = 0.02 and P = 0.01, respectively); patients with rapid progressing disease had the highest levels at both time points. Distribution of IL-10 and IFNγ genotypes was equal among patients from the progression groups.CONCLUSION: IL-10 serum levels associate inversely with age and C-peptide. As age and C-peptide also associate, a triangular association is proposed. Genetic influence on IL-10 production seems to be masked by distinct disease mechanisms. Increased serum IFNγ concentrations associate with rapid disease progression. Functional genetic variants do not associate with a single progression pattern group, implying that disease processes override genetically predisposed cytokine production.

- Objective: Proinsulin is a marker of beta-cell distress and dysfunction in type 2 diabetes and transplanted islets. Proinsulin levels are elevated in patients newly diagnosed with type 1 diabetes. Our aim was to assess the relationship between proinsulin, insulin dose-adjusted haemoglobin A1c (IDAA1C), glucagon-like peptide-1 (GLP-1), glucagon, and remission status the first year after diagnosis of type 1 diabetes.Methods: Juvenile patients (n = 275) were followed 1, 6, and 12 months after diagnosis. At each visit, partial remission was defined as IDAA1C = 9%. The patients had a liquid meal test at the 1-, 6-, and 12-month visits, which included measurement of C-peptide, proinsulin, GLP-1, glucagon, and insulin antibodies (IA).Results: Patients in remission at 6 and 12 months had significantly higher levels of proinsulin compared to non-remitting patients (p < 0.0001, p = 0.0002). An inverse association between proinsulin and IDAA1C was found at 1 and 6 months (p = 0.0008, p = 0.0022). Proinsulin was positively associated with C-peptide (p < 0.0001) and IA (p = 0.0024, p = 0.0068, p < 0.0001) at 1, 6, and 12 months. Glucagon (p < 0.0001 and p < 0.02) as well as GLP-1 (p = 0.0001 and p = 0.002) were significantly lower in remitters than in non-remitters at 6 and 12 months. Proinsulin associated positively with GLP-1 at 1 month (p = 0.004) and negatively at 6 (p = 0.002) and 12 months (p = 0.0002).Conclusions: In type 1 diabetes, patients in partial remission have higher levels of proinsulin together with lower levels of GLP-1 and glucagon compared to patients not in remission. In new onset type 1 diabetes proinsulin level may be a sign of better residual beta-cell function.

- Background: Long-term stress leading to burnout symptoms is prevalent in parents of chronically ill children. The aim of the study was to evaluate the effect of a group intervention by measuring changes in self-rated clinical burnout and performance-based self-esteem. In addition, the parental perceptions of the acceptability of the intervention were explored.Methods: Previously, we have explored the prevalence of clinical burnout in parents of patients 1–18 years with type 1 diabetes mellitus (T1DM) and inflammatory bowel disease (IBD) in the county of Örebro. All parents who exhibited clinical burnout symptoms in accordance with the Shirom–Melamed Burnout Questionnaire (SMBQ) were then invited to participate in a group intervention, which was evaluated in the present small-scale study. The group intervention consisted of eight sessions over a 12-week period, including education about behaviour, cognition and symptoms associated with burnout, intending to help the parents to develop adequate strategies for coping with and reducing stress. We evaluated the effect of the intervention in terms of self-rated clinical burnout and performance-based self-esteem (PBSE). In addition, the acceptability of the intervention was evaluated by analyses of recruitment and retention and self-reports from parents.Results: Sixteen parents (13 of children with TIDM and three of children with IBD) out of 104 reporting clinical burnout participated in the intervention. All participants completed the intervention, and the mean attendance rate at all sessions was 90%. Parents’ subjective evaluations were mainly positive, and SMBQ (p = 0.01) and PBSE scale (p = 0.04) measurements were significantly reduced, which effects remained 6 months after completion of the intervention.Conclusions: Despite the small-scale study, we consider that this intervention for parents with clinical burnout was appreciated and well accepted. The significant reduction in clinical burnout symptoms requires further evaluation in randomised controlled studies based on larger groups of parents.

- Purpose: To explore how mothers experiencing burnout describe their mothering of a child with type 1 diabetes mellitus (T1DM), with a focus on their experienced need for control and self-esteem.Methods: This study used a qualitative, descriptive design and aimed to reveal the experience of mothering a child with diabetes when experiencing burnout. Twenty-one mothers of children with T1DM who were experiencing burnout participated in this study. Data were collected via semi-structured interviews, and content analysis was performed.Results: The main results (latent content of the data) were interpreted in one theme, Mission impossible, an inner feeling derived from an extremely challenging experience of mothering, encompassing involuntary responsibility and constant evaluation. Two sub-themes emerged: Forced to provide extraordinary mothering and Constant evaluation of the mothering.Conclusions: In addition to monitoring the health of the child with T1DM, it is important for clinicians to pay attention to how mothers experience their daily life in order to support those who are at risk of developing burnout, as well as those who are experiencing burnout. The wellbeing of the mother could influence the wellbeing of the child, as well as the entire family. Further research on perceived parental responsibility, gender differences, psychosocial factors, and burnout is needed.Practice Implications: Knowledge and understanding of how mothers suffering from burnout experience mothering a child with diabetes could help nurses, social workers, psychologists and counselors conducting pediatric diabetes care become more attentive to the mother's situation and have procedures for counseling interventions.

- AIMS: To compare the glycaemic response to meals with different fat content in adolescents with Type 1 diabetes mellitus (T1DM) and to investigate associations with gastric emptying.METHODS: In this randomized, cross-over study, paired results were obtained from seven adolescents with T1DM who ingested on different days two meals with the same carbohydrate and protein content, but different fat and energy content (2 and 38 g fat, 320 and 640 kcal, respectively). Paracetamol was mixed into the meals and gastric emptying was estimated by the paracetamol absorption method. All subjects were normoglycaemic and given 7 IU insulin aspart at commencement of ingestion. Postprandial blood samples were taken during 4 h.RESULTS: The areas under the curves for plasma glucose and serum paracetamol concentrations were larger after the low-fat than after the high-fat meal during the first 2 h (P = 0.047 and P = 0.041, respectively). The difference between meals in time-to-peak in glucose and paracetamol concentrations did not reach statistical significance (high-fat vs. low-fat meal: 210 min (120-240) vs. 120 min (50-240), P = 0.080 and 120 min (75-180) vs. 60 min (60-120), P = 0.051, respectively). Changes in glucose concentrations correlated with simultaneous changes in paracetamol concentrations (P < 0.001).CONCLUSIONS: For the first time, we have shown that the initial glycaemic response is reduced after a meal with higher compared with a meal with lower fat content in adolescents with T1DM given a rapid-acting insulin analogue preprandially. The type and dose of preprandial insulin may need adjustment to the fat content of the meal to reach postprandial normoglycaemia.

- AIMS: The aims were to describe the food habits of adolescents with Type 1 diabetes (Type 1 DM) and to compare them with healthy control subjects; to describe the distribution of energy-providing nutrients in patients and compare it with current recommendations and previous reports; and finally, to investigate associations between dietary intake and glycaemic control. METHODS: One hundred and seventy-four adolescents with Type 1 DM and 160 age- and sex-matched healthy control subjects completed a validated food frequency questionnaire, and 38 randomly chosen patients completed a prospective 4-day food record. RESULTS: Patients ate more regularly, and more often ate fruit and fruit juice, potatoes and root vegetables, meat, fish, egg, offal and sugar-free sweets than control subjects. Control subjects more often ate ordinary sweets and snacks. Patients chose coarse rye bread and dairy products with less fat to a greater extent than control subjects. Patients were heavier than control subjects. The intake of saturated fat was higher in patients compared with recommendations and, for boys with diabetes, the intake of protein was higher than recommended. Patients with poorer glycaemic control ate vegetables, fruit and fish less often than patients with better control. CONCLUSIONS: The food habits of adolescents with Type 1 DM were healthier than those of control subjects. The intake of energy-providing nutrients was in line with current recommendations and showed improvements compared with previous reports, with the exception of fibre intake. The association between dietary intake and glycaemic control needs further investigation in prospective studies.

- The Hessian of the entropy function can be thought of as a metric tensor on the state space. In the context of thermodynamical fluctuation theory Ruppeiner has argued that the Riemannian geometry of this metric gives insight into the underlying statistical mechanical system; the claim is supported by numerous examples. We study this geometry for some families of black holes. It is flat for the BTZ and Reissner-Nordstrom black holes, while curvature singularities occur for the Reissner-Nordstrom-anti-de Sitter and Kerr black holes.

- Aim: Skinfold measurement is an inexpensive and widely used technique for assessing the percentage of body fat (%BF). This study assessed the accuracy of prediction equations for %BF based on skinfold measurements compared to dual-energy X-ray absorptiometry (DXA) in girls with type 1 diabetes and healthy age-matched controls.Methods: We included 49 healthy girls and 44 girls with diabetes aged 12 to 19 years old, comparing the predicted %BF based on skinfold measurements and the %BF values obtained by a Lunar DPX-L scanner. The agreement between the methods was assessed by using an Bland-Altman plot.Results: The skinfold measurements were significantly higher in girls with diabetes (p=0.003) despite a non-significant difference in total %BF (p=0.1). A significant association between bias and %BF was found for all tested equations in the Bland-Altman plots. Regression analysis showed that the association between skinfold measurements and %BF measured by DXA differed significantly (p=0.039) between the girls with diabetes and the healthy controls.Conclusion: The accuracy of skinfold thickness equations for assessment of %BF in adolescent girls with diabetes is poor in comparison with DXA measurements as criteron. Our findings highlight the need for the development of new prediction equations for girls with type 1 diabetes.

- 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.
