Determinants of trabecular bone score and prevalent vertebral fractures in women with fragility fractures: a cross-sectional sub-study of NoFRACT.

Determinants of trabecular bone score (TBS) and vertebral fractures assessed semiquantitatively (SQ1-SQ3) were studied in 496 women with fragility fractures. TBS was associated with age, parental hip fracture, alcohol intake and BMD, not SQ1-SQ3 fractures. SQ1-SQ3 fractures were associated with age, prior fractures, and lumbar spine BMD, but not TBS. INTRODUCTION: Trabecular bone score (TBS) and vertebral fractures assessed by semiquantitative method (SQ1-SQ3) seem to reflect different aspects of bone strength. We therefore sought to explore the determinants of and the associations between TBS and SQ1-SQ3 fractures. METHODS: This cross-sectional sub-study of the Norwegian Capture the Fracture Initiative included 496 women aged ≥ 50 years with fragility fractures. All responded to a questionnaire about risk factors for fracture, had bone mineral density (BMD) of femoral neck and/or lumbar spine assessed, TBS calculated, and 423 had SQ1-SQ3 fracture assessed. RESULTS: Mean (SD) age was 65.6 years (8.6), mean TBS 1.27 (0.10), and 33.3% exhibited SQ1-SQ3 fractures. In multiple variable analysis, higher age (ßper SD = - 0.26, 95% CI: - 0.36,- 0.15), parental hip fracture (ß = - 0.29, 95% CI: - 0.54,- 0.05), and daily alcohol intake (ß = - 0.43, 95% CI - 0.79, - 0.08) were associated with lower TBS. Higher BMD of femoral neck (ßper SD = 0.34, 95% CI 0.25-0.43) and lumbar spine (ßper SD = 0.40, 95% CI 0.31-0.48) were associated with higher TBS. In multivariable logistic regression analyses, age (ORper SD = 1.94, 95% CI 1.51-2.46) and prior fragility fractures (OR = 1.71, 95% CI 1.09-2.71) were positively associated with SQ1-SQ3 fractures, while lumbar spine BMD (ORper SD = 0.75 95% CI 0.60-0.95) was negatively associated with SQ1-SQ3 fractures. No association between TBS and SQ1-SQ3 fractures was found. CONCLUSION: Since TBS and SQ1-SQ3 fractures were not associated, they may act as independent risk factors, justifying the use of both in post-fracture risk assessment.

Longitudinal changes in brain morphology from 4 weeks to 12 months after mild traumatic brain injury: Associations with cognitive functions and clinical variables.

OBJECTIVE: To investigate longitudinal changes in cortical and subcortical volumes in patients with mild traumatic brain injury (MTBI) and to evaluate whether such changes were associated with self-reported post-concussive symptoms, global functional outcomes and neuropsychological functioning. METHODS: This was a prospecitve, longitudinal cohort study of patients with complicated (i.e presence of intracranial abnormalities on the day of injury CT) and uncomplicated MTBI (i.e, absence of intracranial abnormalities). Magnetic resonance imaging (MRI) was performed at approximately 4 weeks and 12 months. We utilized a 3T MRI system, cortical reconstruction and volumetric segmentation by FreeSurfer software. We included 33 patients with uncomplicated and 29 with complicated MTBI, who were aged 16-65 years. RESULTS: 12 months after MTBI, significant within-group volume reductions were detected in the left accumbens area and right caudate nucleus for both patients groups, but no significant differences between the groups were revealed. No associations between volumetric variables and post-concussive symptoms or global functioning were found. The left temporal thickness was significantly associated with executive functioning. CONCLUSION: Structural subcortical alterations occur after complicated and uncomplicated MTBIs but these findings were not associated with symptoms burden or functional outcomes. Nonetheless, worse executive functioning was found in patients with shrinkage of the left temporal lobe.

Impact of acute kidney injury on patient outcome in out-of-hospital cardiac arrest: a prospective observational study.

BACKGROUND: Kidney disease after out-of-hospital cardiac arrest (OHCA) is incompletely described. We examined the occurrence of acute kidney injury (AKI) in OHCA patients and impact of AKI, with or without renal replacement therapy (RRT), on 6-month mortality and neurological outcome. METHODS: Prospective study at Oslo University Hospital, Oslo, Norway. Adult resuscitated comatose OHCA patients treated with targeted temperature management at 33°C for 24 h were included. AKI and chronic kidney disease (CKD) were classified according to the Kidney Disease Improving Global Outcomes (KDIGO) guidelines. Main outcomes were 6-month mortality and good neurological outcome defined as Cerebral Performance Category 1-2. RESULTS: Among 245 included patients (84% males, mean age 61 years), 11 (4%) had previously known CKD and 112 (46%) developed AKI. Overall 6-month outcome revealed that 112 (46%) died and 123 (50%) had good neurological outcome. Compared with no kidney disease, the presence of AKI was significantly associated with 6-month mortality (odds ratio (OR) 3.17, 95% confidence interval (CI) 1.95-5.43, P < 0.001) and good neurological outcome (OR 0.28, 95% CI 0.16-0.48, P < 0.001). Six-month mortality (50 vs. 61%, P = 0.401) and frequency of good neurological outcome (44 vs. 35%, P = 0.417) were not statistically different in AKI patients with or without RRT, also after excluding patients where RRT was withheld due to futility. CONCLUSIONS: Kidney disease occurred in about half of patients successfully resuscitated from OHCA. Presence of AKI, but not RRT, was associated with unfavourable 6-month outcome.

Chest compression duration influences outcome between integrated load-distributing band and manual CPR during cardiac arrest.

BACKGROUND: The Circulation Improving Resuscitation Care (CIRC) Trial found equivalent survival in adult out-of-hospital cardiac arrest (OHCA) patients who received integrated load-distributing band CPR (iA-CPR) compared to manual CPR (M-CPR). We hypothesized that as chest compression duration increased, iA-CPR provided a survival benefit when compared to M-CPR. METHODS: A pre-planned secondary analysis of OHCA of presumed cardiac etiology from the randomized CIRC trial. Chest compressions duration was defined as the total number of minutes spent on compressions during resuscitation and identified from transthoracic impedance and accelerometer data recorded by the EMS defibrillator. Logistic regression was used to model the interaction between treatment and duration of chest compressions and was covariate-adjusted for trial site, patient age, witnessed arrest, and initial shockable rhythm. Primary outcome was survival to hospital discharge. RESULTS: We enrolled 4231 subjects and of those, 2012 iA-CPR and 2002 M-CPR had complete outcome and duration of chest compressions data. While covariate-adjusted odds ratio for survival to hospital discharge was 1.86 in favor of iA-CPR (95% CI 1.16-3.0), there was an interaction between duration and study arm. When this was factored into the multivariate equation, the odds ratio for survival to hospital discharge showed a significant benefit for iA-CPR vs. M-CPR for chest compression duration greater than 16.5 min. CONCLUSION: After adjusting for compression duration and duration-treatment interaction, iA-CPR showed a significant benefit for survival to hospital discharge vs. M-CPR in patients with OHCA if chest compression duration was longer than 16.5 min.

Volumetric and morphometric MRI findings in patients with mild traumatic brain injury.

OBJECTIVE: This study compared cortical and sub-cortical volumes between patients with complicated (i.e. presence of intracranial abnormality on the day-of-injury CT) and uncomplicated (i.e. absence of intracranial abnormality) mild traumatic brain injury (MTBI) 4 weeks post-injury. The study hypothesized regionally decreased brain volumes and reduced cortical thickness in patients with complicated MTBIs compared with uncomplicated MTBI. METHODS: This study was part of a larger 2 years cohort study on MTBI. Baseline clinical and magnetic resonance imaging (MRI) data were compared for those with complicated and uncomplicated MTBI. It identified 168 patients with MTBI (90 uncomplicated and 78 complicated), aged 16-65 years. 3T MRI-system (Signa HDxt, GE Medical Systems, Milwaukee, WI) and cortical reconstruction and volumetric segmentation by FreeSurfer software have been used. RESULTS: No significant differences between uncomplicated and complicated MTBIs were found in neuroanatomic volumes and cortical thickness after controlling for age, gender and education. The complicated MTBI group showed larger ventricles compared with the uncomplicated group, but this effect diluted when adjusting for potential confounders. CONCLUSION: The study findings suggest that the classification of complicated and uncomplicated MTBI may be too broad to differentiate volumetric and morphometric effects of injury in the early post-injury phase.

An up-date on health-related quality of life in myasthenia gravis -results from population based cohorts.

UNLABELLED: Current available therapies control Myasthenia gravis (MG) reasonably well, but Health Related Quality of life (HRQOL) remains lower than expected. The aim was provide insights in how HRQOL in MG stands across borders and time, compare the scores to general population controls and other chronic disorders and assess the impact of potential predictors for quality of life such as a) clinical characteristics b) antibodies c) thymoma and d) treatment in a population-based cohort. METHODS: We designed a population-based cross-sectional study including 858 patients, 373 from Norway and 485 from the Netherlands. The Short Form Health Survey 36 (SF-36) and a cross-cultural validated questionnaire were used. Data were in addition compared to the general population, other chronic diseases and previous studies. RESULTS: Mean physical composite score was 59.4 and mental composite score 69.0 with no differences between the countries. The mean HRQOL score was lower in patients with bulbar and generalized symptoms (p < 0.001) compared to sex and age adjusted healthy controls, but not in patients with ocular symptoms or patients in remission. Multivariate analysis revealed that female gender, generalized symptoms and use of secondary immunosuppressive drugs at the time of testing were risk factors for reduced HRQOL. CONCLUSIONS: Remission and absence of generalized symptoms were favorable factors for HRQOL in MG patients. Historically, the HRQOL levels have not changed since 2001 and no new clinical predictors could be detected in this exhaustive population-based study. Further studies should explore the impact of non clinical factors like ethnic variations, socio-economic and hormonal factors on HRQOL.

Virtual reality as a method of cognitive training of processing speed, working memory, and sustained attention in persons with acquired brain injury: a protocol for a randomized controlled trial.

BACKGROUND: Acquired brain injury (ABI) often leads to persisting somatic, cognitive, and social impairments. Cognitive impairments of processing speed, sustained attention, and working memory are frequently reported and may negatively affect activities of daily living and quality of life. Rehabilitation efforts aiming to retrain these cognitive functions have often consisted of computerized training programs. However, few studies have demonstrated effects that transfer beyond the trained tasks. There is a growing optimism regarding the potential usefulness of virtual reality (VR) in cognitive rehabilitation. The research literature is sparse, and existing studies are characterized by considerable methodological weaknesses. There is also a lack of knowledge about the acceptance and tolerability of VR as an intervention method for people with ABI. The present study aims to investigate whether playing a commercially available VR game is effective in training cognitive functions after ABI and to explore if the possible effects transfer into everyday functioning. METHODS: One hundred participants (18-65 years), with a verified ABI, impairments of processing speed/attention, and/or working memory, and a minimum of 12 months post injury will be recruited. Participants with severe aphasia, apraxia, visual neglect, epilepsy, and severe mental illness will be excluded. Participants will be randomized into two parallel groups: (1) an intervention group playing a commercial VR game taxing processing speed, working memory, and sustained attention; (2) an active control group receiving psychoeducation regarding compensatory strategies, and general cognitive training tasks such as crossword puzzles or sudoku. The intervention period is 5 weeks. The VR group will be asked to train at home for 30 min 5 days per week. Each participant will be assessed at baseline with neuropsychological tests and questionnaires, after the end of the intervention (5 weeks), and 16 weeks after baseline. After the end of the intervention period, focus group interviews will be conducted with 10 of the participants in the intervention group, in order to investigate acceptance and tolerability of VR as a training method. DISCUSSION: This study will contribute to improve understanding of how VR is tolerated and experienced by the ABI population. If proven effective, the study can contribute to new rehabilitation methods that persons with ABI can utilize in a home setting, after the post-acute rehabilitation has ended.

Body mass index and the risk of meningioma, glioma and schwannoma in a large prospective cohort study (The HUNT Study).

BACKGROUND: Obesity increases the risk for a number of solid malignant tumours. However, it is not clear whether body mass index (BMI) and height are associated with the risk of primary tumours of the central nervous system (CNS). METHODS: In a large population study (The Nord-Trøndelag Health Study (HUNT Study)) of 74 242 participants in Norway, weight and height were measured. During follow-up, incident CNS tumours were identified by individual linkage to the Norwegian Cancer Registry. Sex- and age-adjusted and multivariable Cox regression analyses were used to evaluate BMI and height in relation to the risk of meningioma, glioma and schwannoma. RESULTS: A total of 138 meningiomas, 148 gliomas and 39 schwannomas occurred during 23.5 years (median, range 0-25) of follow-up. In obese women (BMI ≥ 30 kg m(-2)), meningioma risk was 67% higher (hazard ratio (HR)=1.68, 95% confidence interval (CI): 0.97-2.92, P-trend=0.05) than in the reference group (BMI 20-24.9 kg m(-2)), whereas no association with obesity was observed in males. There was no association of BMI with glioma risk, but there was a negative association of overweight/obesity (BMI ≥ 25 kg m(-2)) with the risk of schwannoma (HR=0.48, 95% CI: 0.23-0.99). However, the schwannoma analysis was based on small numbers. Height was not associated with the risk for any tumour subgroup. CONCLUSION: These results suggest that BMI is positively associated with meningioma risk in women, and possibly, inversely associated with schwannoma risk.

Smoking and socio-economic status may affect myasthenia gravis.

BACKGROUND AND PURPOSE: The influence of environmental factors in myasthenia gravis (MG) is unknown. The aim of this cross-sectional population-based study was to investigate if smoking and socio-economic status (SES) were associated with MG in the Norwegian population. METHODS: Subjects were 491 MG patients identified in Norway at the time of the study (point prevalence 12.7/100 000). A questionnaire covering smoking habits and markers of SES (education and occupation) was mailed to all patients. Population data were obtained from Statistics Norway. RESULTS: A total of 375 (76.6%) patients completed the questionnaire (236 women, mean age 59 ± 18 years), of which 193 reported to be early onset MG (EOMG, onset ≤40 years, 155 women). Compared with the general population, current smoking was more prevalent amongst MG patients [risk ratio (RR) 1.5; 95% confidence interval (CI) 1.1-1.9], most of whom had EOMG. Female MG patients had higher education compared with the general population (RR 4.5; 95% CI 3.2-6.2). Male MG patients were similar to the general population regarding both education and occupation, except for a subset of late onset MG who had shorter education (RR 1.9; 95% CI 1.1-3.2) and had worked in crafts and related trades. About half of working age MG patients received disability pension, a finding significantly related to low educational level and a more severe disease course (P < 0.001). CONCLUSION: This is the first report indicating that smoking and SES may affect MG. Further studies investigating their role as potential risk factors are warranted.

Development and validation of a self-administered questionnaire for myasthenia gravis patients.

BACKGROUND: To date, the investigation of the epidemiological profile of myasthenia gravis (MG) is sparse, and the influence of environmental and lifestyle factors on the occurrence of the disease remains thus unknown. The main aim of this study, which is part of a European collaborative project (EuroMyasthenia), was to develop a self-administered questionnaire to investigate these potential predisposing factors for MG. No instrument for investigating these particular factors has previously been designed for MG patients. MATERIAL AND METHODS: The questionnaire was developed in 3 stages: (1) devising a draft questionnaire based on questions derived from previously validated questionnaires and self-designed questions on MG characteristics; (2) testing the questionnaire on Norwegian MG patients (n = 57), and (3) assessing the content and criterion validity, and test-retest reliability, of the final questionnaire. RESULTS: The questionnaire was easy to use and showed good feasibility for MG patients. Psychometric evaluation established the validity and reliability of the self-designed questions on MG characteristics. CONCLUSION: This is the first validated instrument developed to identify self-assessed environmental factors and potential predisposing factors for MG, and suitable for use in large-scale epidemiological studies.

Changes in bone quality after Roux-en-Y gastric bypass: A prospective cohort study in subjects with and without type 2 diabetes.

BACKGROUND: Obesity and type 2 diabetes (T2D) are associated with an increased risk of skeletal fractures despite a normal areal bone mineral density (aBMD) and low bone turnover, possibly due to reduced bone material strength. Roux-en-Y gastric bypass (RYGB) enables a substantial and persistent weight loss and resolution of obesity related comorbidities such as T2D. However, the procedure induces a decrease in aBMD and increased bone turnover and fracture rate. To our knowledge, changes in bone material strength after RYGB have not been explored. This study aimed to evaluate changes in factors influencing bone quality; bone material strength, aBMD and bone turnover markers, in a population with morbid obesity undergoing RYGB and whether these changes differed in participants with and without T2D. We also sought to assess factors associated with bone material strength and bone mineral density in obese subjects before and after RYGB. METHODS: We examined 34 participants before and one year after RYGB, of whom 13 had T2D. Bone material strength index (BMSi) was evaluated by impact microindentation, aBMD and body composition by Dual energy X-ray absorptiometry, levels of bone turnover markers and calciotropic hormones were estimated from fasting serum samples. Participants with and without T2D were comparable before surgery, with the exception of glycosylated hemoglobin (HbA1c). RESULTS: Preoperatively, BMSi was inversely associated with BMI, ßunadjusted -1.1 (-1.9 to -0.28), R2=0.19, p=0.010, and this association remained significant after adjusting for age and gender. After RYGB the participants had lost a mean±SD of 33.9±10.9kg, 48.7±14.2 % of total body fat, increased physical activity, unchanged vitamin D levels, and all but one of the 13 participants with T2D were in diabetes remission. BMSi increased from 78.1±8.5 preoperatively to 82.0±6.4 one year after RYGB, corresponding to an increase of 4.0±9.8 in absolute units or 6.3±14.0 %, p=0.037. The increase was comparable in participants with and without T2D. In subjects with T2D, a larger decrease in HbA1c was associated with a larger increase in BMSi ßunadjusted -9.2 (-16.5 to -1.9), R2=0.47, p=0.019. Bone turnover markers (CTX-1 and PINP) increased by 195.1±133.5 % and 109.5±70.6 %, respectively. aBMD decreased by 3.9±5.5 % in the lumbar spine, 8.2±4.6 % in the femoral neck, 11.6±4.9 % in total hip and 9.4±3.8 % in total body. CONCLUSION: Our findings indicate that bone material strength improves despite an increase in bone turnover and a decrease in aBMD one year after RYGB. Trends were statistically comparable in participants with and without T2D. However, improved glucose control was associated with improved bone material strength in participants with T2D.

Functional outcome and health-related quality of life 10 years after moderate-to-severe traumatic brain injury.

OBJECTIVES: To describe the functional outcome and health-related quality of life (HRQL) 10 years after moderate-to-severe traumatic brain injury (TBI). MATERIAL AND METHODS: A retrospective, population-based study of 62 survivors of working-age with moderate-to-severe TBI injured in 1995/1996, and hospitalized at the Trauma Referral Center in Eastern Norway. Functional status was measured by the Glasgow Outcome Scale-Extended (GOS-E). HRQL was assessed by the SF-36 questionnaire. RESULTS: The mean current-age was 40.8 years. The frequency of epilepsy was 19% and the depression rate 31%. A majority had good recovery (48%) or moderate disability (44%). Employment rate was 58%. Functional and employment status were associated with initial injury severity in contrast to HRQL. Study patients had significantly lower scores in all SF-36 dimensions when compared with the general Norwegian population. CONCLUSION: At 10-years follow-up, our study population is still in their most productive years and affected domains should be considered in long-term follow-up and intervention programs.

Sweets, snacking habits, and skipping meals in children and adolescents on intensive insulin treatment.

AIM: To examine the association between skipping meals and snacking events and dietary and clinical characteristics in children and adolescents using modern insulin treatment. METHODS: Dietary intake was recorded for 4 d in food diaries in 655 young diabetic patients. Number of meals and snacking events was recorded in a separated questionnaire, while clinical data were obtained from case record forms. Skipping meals refer to consuming a main meal (e.g., breakfast) five times a week or less. RESULTS: Modern insulin treatment may favor a more flexible lifestyle. This study shows that there are fewer young diabetic patients who skip meals than non-diabetic controls (p < 0.001) even when using modern intensified insulin treatment. However, skipping meals among young diabetic patients was associated with negative characteristics such as having suboptimal hemoglobin A1c (HbA1c) (OR 4.7, p = 0.02), higher low-density lipoprotein (LDL) cholesterol levels (OR 4.0, p < 0.001), watching more TV (OR 3.6, p < 0.001), being overweight (OR 2.8, p = 0.03), as well as having a higher intake of added sugar (OR 2.1, p = 0.01) and lower intake of fiber (OR 0.2, p = 0.04) compared with those not skipping meals. Having more than two snacking events during the day was associated with higher HbA1c, higher intake of added sugar and sweets, and spending more hours in front of the TV or personal computer. CONCLUSIONS: In general, fewer children and adolescents with type 1 diabetes skip meals compared with healthy peers. Those who skip meals and have more snacking events have poorer glycemic control and less healthy dietary and leisure habits.

Juvenile myasthenia gravis in Norway: A nationwide epidemiological study.

BACKGROUND: The aim of this study was to assess the incidence rate and prevalence of autoimmune myasthenia gravis (MG) among children in Norway. METHODS: This retrospective population-based study was performed in Norway from January 2012 to December 2013. Cases of juvenile MG (JMG) with onset < 18 years were identified through searches in coding systems of electronic patient records at the 15 main hospitals in Norway from 1989 to 2013. In addition, the acetylcholine receptor antibody database at Haukeland University Hospital and the clinical nationwide MG database at Oslo University Hospital were searched for cases of JMG. Diagnosis and age at onset were verified through medical records. Incidence and prevalence rates were calculated using the Norwegian population as reference. RESULTS: In total 63 unique JMG cases were identified. This corresponds to an average annual incidence rate of 1.6 per million. Incidence rate was stable over the study period. Prevalence of JMG was 3.6-13.8 per million. Females constituted the majority of JMG cases (55 vs 8 males). The risk of JMG was higher among females both in the postpubertal and prepubertal group (p < 0.001 and p = 0.02, respectively). CONCLUSION: This study confirms the rarity of JMG in Norway, especially among males, and shows a stable incidence rate over the last 25 years.

Ethnicity and acute myocardial infarction: risk profile at presentation, access to hospital management, and outcome in Norway.

BACKGROUND: Previous studies in North America have shown ethnic variation in the presentation of acute myocardial infarction (AMI), and sex and racial differences in the management and outcome of AMI. In the present study, our aim was to investigate the risk profile of AMI for patients with minority background compared with indigenous Norwegians, at hospital presentation, and to investigate racial differences in hospital care and outcomes. PATIENTS AND METHODS: A dual-design study was adopted: a cross-sectional study to examine ethnic differences of risk prevalence at hospital presentation and a cohort study to estimate access to angiography, percutaneous coronary intervention (PCI), and hospital and long-term mortality. From a study population of 3105 patients with AMI presenting at Oslo University Hospital between January 1, 2006 and December 31, 2007, we identified 147 cases of AMI in patients with minority background and selected a random sample of 588 indigenous Norwegians with AMI as controls. Prognostic and explanatory strategies were used in the analysis. RESULTS: Compared with indigenous Norwegians with AMI, AMI patients with minority background suffered their AMI 10 years younger, were generally male, were twice as likely to be smokers, three times as likely to have type 2 diabetes, had lower high-density lipoprotein levels. This group also had 50% less history of hypertension. In terms of hospital care, AMI patients with minority background had shorter times from onset of symptoms to PCI and the same frequency of access to angiography and acute PCI as indigenous Norwegians when adjusting for the confounding effect of age, sex, and nature of myocardial infarction with or without ST elevation. CONCLUSION: At presentation to hospital, patients with minority background had a higher risk profile and a shorter time from onset of symptoms to admission to catheterization laboratory than indigenous Norwegians, but the same access to angiography and acute PCI during hospitalization.

High prevalence of cardiovascular risk factors in children and adolescents with type 1 diabetes: a population-based study.

AIMS/HYPOTHESIS: The risk of dying of cardiovascular disease (CVD) before the age of 40 years is increased nearly 20-fold in patients with type 1 diabetes compared with non-diabetic persons. The aim of this study was to evaluate the prevalence of CVD risk factors in a population-based study of children and adolescents with type 1 diabetes. METHODS: CVD risk factors were examined according to the American Diabetes Association criteria in 2005. Of 26 paediatric clinics in Norway, 25 participated with 1,658 patients, 85% of those eligible. Mean age was 13.1 years and mean diabetes duration 5.7 years. RESULTS: HbA(1c) was above the target level in 71.4%. A positive family history of early CVD and/or diabetes was found in 33% of participants. LDL-cholesterol was >2.6 mmol/l in 34.5% and HDL-cholesterol was <1.1 mmol/l in 6.9% of participants. Blood pressure was above the 90th percentile by age, sex and height in 7% and above the 95th percentile in 4% of participants. Four per cent of participants were obese, 3% of those >or=12 years of age reported smoking and 1% of all participants had persistent microalbuminuria. Only 0.2% of the patients were receiving statin and 0.3% anti-hypertensive treatments. Dietary habits and physical activity level were evaluated in some patients. Almost all had higher intake of dietary fat and lower intake of fibre than recommended. A large part was less active and watched more TV than recommended. CONCLUSIONS/INTERPRETATION: Of the participants, 86% had at least one, 45% at least two and 15% at least three CVD risk factors. Few patients were treated with statins and anti-hypertensive drugs.

The influence of dietary intake and meal pattern on blood glucose control in children and adolescents using intensive insulin treatment.

AIMS/HYPOTHESIS: We studied dietary factors and their association with blood glucose control in type 1 diabetic children and adolescents using intensive insulin treatment. MATERIALS AND METHODS: A total of 550 children and adolescents with type 1 diabetes mellitus (age 2-19 years) recorded their diet for 4 days in pre-coded food diaries. Of the study group, 34% used insulin pumps, 43% used four or more injections and 16% three injections per day. HbA(1c) was related to targets of optimal blood glucose control defined by the International Society for Pediatric and Adolescent Diabetes (ISPAD). RESULTS: Adolescents with optimal glucose control (HbA(1c) < or = 7.5%) had a lower intake of added sugar (7.7 vs 9.1% of energy intake, p = 0.004), a higher intake of fibre (19.3 vs 17.0 g/day, p = 0.01) and a higher intake of fruits and vegetables (257 vs 227 g/day, p = 0.04) than those with suboptimal metabolic control (HbA(1c) > 7.5%). Multiple regression analysis in adolescents showed that fibre and meal pattern were significantly associated with blood glucose control (effect fibre intake = -0.02, p = 0.04, effect having breakfast regularly = -0.89, p = 0.009). In children meal pattern was associated with blood glucose control (effect having dinner regularly = -0.66, p = 0.02, effect having supper regularly = -0.78, p = 0.03). CONCLUSIONS/INTERPRETATION: In diabetic adolescents both intake of fibre and having a regular meal pattern are associated with blood glucose control. Lower intake of added sugar and sugar-sweetened soft drinks and higher intake of fruits and vegetables are observed among those with optimal compared with those with suboptimal blood glucose control. Dietary guidance should be intensified during adolescence to improve dietary intake and blood glucose control.
