- OBJECTIVE: To investigate the effects of a selective serotonin reuptake inhibitor (SSRI) on the neuroendocrine and autonomic nervous system perturbations found in abdominal obesity. DESIGN: Treatment for 6 months with citalopram and for 6 months with placebo using a double-blind, cross-over design, with a 2-month wash-out period between treatment periods. SUBJECTS: Sixteen healthy men, 45-60 years, moderately obese and with an abdominal fat distribution. MEASUREMENTS: Anthropometry, three different depression rating scales, serum lipids, testosterone, IGF-I, oral glucose tolerance test (OGTT), pituitary stimulation with corticotropin releasing hormone (CRH), arithmetic stress test, and excretion of cortisol and metoxycatecholamines in urine, collected during 24 h. RESULTS: Cortisol concentrations in the morning were low before treatment, indicating a perturbed function of the hypothalamic-pituitary-adrenal (HPA) axis. After treatment with citalopram morning cortisol concentrations rose to normal. Cortisol concentrations after stimulation with CRH or stress were elevated by citalopram treatment, but urinary cortisol excretion was unchanged. The glucose concentrations after OGTT (120 min) tended to be reduced, with unchanged insulin concentrations, whilst other metabolic values did not change during treatment. Heart rate after administration of CRH, and during laboratory stress test, decreased by treatment with citalopram. Diurnal urinary excretion of metoxycatecholamines tended to decrease. Neither body mass index nor waist/hip circumference ratio decreased. Depression scores were within normal limits before treatment and did not change. CONCLUSION: The results of this pilot study indicate improvements in the regulation of neuroendocrine-autonomic systems as well as metabolism in abdominal obesity during treatment with an SSRI.

- Child health is taking the back seat in development strategies. In summarising a newly released collaborative report, this paper calls for a novel conceptual model where child health takes centre stage in relation to the 2030 Agenda and the Sustainable Development Goals. It lays out five principles by which renewed effort and focus would yield the most benefit for children and adolescents. These include: re-defining global child health in the post-2015 era by placing children and adolescents at the centre of the Sustainable Development Goals; striving for equity; realising the rights of the child to thrive throughout the life-course; facilitating evidence informed policy-making and implementation; and capitalising on interlinkages within the SDGs to galvanise multisectoral action. These five principles offer models that together have the potential of improving design, return and quality of global child health programs while re-energising the 2030 Agenda and the Sustainable Development Goals.

Tidskriftsartikel (refereegranskat)abstract
- Knowledge about age-specific normal values for left ventricular mass (LVM), end-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV) and ejection fraction (EF) by cardiac magnetic resonance imaging (CMR) is of importance to differentiate between health and disease and to assess the severity of disease. The aims of the study were to determine age and gender specific normal reference values and to explore the normal physiological variation of these parameters from adolescence to late adulthood, in a cross sectional study.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The physiological determinants of left ventricular mass (LVM) measured by cardiac magnetic resonance (CMR) imaging are not well defined as prior investigators have studied either adults or adolescents in isolation or have not strictly excluded hypertension or accounted for the effects of exercise habits, haemodynamic, demographic, or body shape characteristics. METHODS: A total of 102 healthy volunteers (12-81 years, 53 males) underwent CMR. All parameters [unstandardized and adjusted for body surface area (BSA)] were analysed according to gender and by adolescence versus adulthood (adolescents <20 years, adults > or = 20 years). The influence of haemodynamic factors, exercise, and demographic factors on LVM were determined with multivariate linear regression. Results: LVM rose during adolescence and declined in adulthood. LVM and LVMBSA were higher in males both in adults (LVM: 188 +/- 22 g versus 139 +/- 21 g, P < 0.001; LVMBSA: 94 +/- 11 g m(-2) versus 80 +/- 11 g m(-2), P < 0.001) and in adolescents when adjusted for BSA (LVM: 128 +/- 29 g versus 107 +/- 20 g, P = 0.063; LVMBSA: 82 +/- 8 g m(-2) versus 71 +/- 10 g m(-2), P = 0.025). In adults, systolic blood pressure (SBP) and self-reported physical activity increased while meridional and circumferential wall stress were constant with age. Multivariate regression analysis revealed age, gender, and BSA as the major determinants of LVM (global R2 = 0.69). CONCLUSIONS: Normal LVM shows variation over a broad age range in both genders with a rise in adolescence and subsequent decline with increasing age in adulthood despite an increase in SBP and physical activity. BSA, age, and gender were found to be major contributors to the variation in LVM in healthy adults, while haemodynamic factors, exercise, and wall stress were not.

- Objective: Limited data, especially from longitudinal studies, are available regarding vascular health assessment in childhood. In this study, we performed longitudinal and cross-sectional studies in healthy children and adolescents to investigate age- and sex-related differences in vascular functions and vascular response to mental stress. Methods: Pulse wave velocity (PWV) was measured by tonometry. Endothelial function and vascular response to mental arithmetic test were assessed using a peripheral artery tonometry device. Data were obtained in 162 adolescents (mean age of 17 years, 94 girls) in a 3-year follow-up study and 241 children (mean age of 10 years, 115 girls) in a first-time investigation. Physical activity was assessed in adolescents by a self-report questionnaire. Results: Our 3-year follow-up study revealed that the increased PWV was greater in male adolescents (0.79 ± 0.79 m/s) than in females (0.27 ± 0.89 m/s, p < 0.001). Adolescents who reported decreased physical activity over the 3-year period had increased arterial stiffness. Comparing the cross-sectional data, we found that sex-related differences in reactive hyperemic response was more apparent by evaluating the overall response curve than measuring the reactive hyperemic index from one arbitrary time point, with lower peak response and smaller area-under-curve found in boys. Moreover, we found that, in response to mental stress, male adolescents had a more vasoconstrictive response, followed by a less vasodilatory response, and needed longer time to return to baseline level than the females. Conclusion: These findings suggest that boys are likely to have adverse changes in vascular health earlier than the age-matched girls.

- Objective: The aim of this study was to examine BMI trajectories from birth throughout childhood, associations with health outcomes at age 13 years, and time frames during which early-life BMI influenced adolescent health. Methods: Participants (1902, 44% male) reported perceived stress and psychosomatic symptoms and were examined for waist circumference (WC), systolic blood pressure (SBP), pulse wave velocity, and white blood cell counts (WBC). BMI trajectory was analyzed using group-based trajectory modeling of retrospective data of weight/height from birth throughout childhood. The authors performed linear regression to assess associations between BMI trajectories and health outcomes at age 13 years, presented as estimated mean differences with 95% CI among trajectories. Results: Three BMI trajectories were identified: normal; moderate; and excessive gain. Adjusting for covariates, adolescents with excessive gain had higher WC (19.2 [95% CI: 18.4–20.0] cm), SBP (3.6 [95% CI: 2.4–4.4] mm Hg), WBC (0.7 [95% CI: 0.4–0.9] × 109/L), and stress (1.1 [95% CI: 0.2–1.9]) than adolescents with normal gain. Higher WC (6.4 [95% CI: 5.8–6.9] cm), SBP (1.8 [95% CI: 1.0–2.5] mm Hg), and stress (0.7 [95% CI: 0.1–1.2]) were found in adolescents with moderate versus normal gain. The association of early-life BMI with SBP started around age 6 years with the excessive gain group, which was earlier than in the normal and moderate gain groups, in which it started at age 12 years. Conclusions: An excessive gain BMI trajectory from birth predicts cardiometabolic risk and stress in 13-year-old individuals.

- Obese adolescents have high concentrations of saturated fatty acids and low omega-3 long-chain polyunsaturated fatty acids (LCUFAs) in plasma phospholipids. We aimed to investigate effects of omega-3 LCPUFA supplementation to obese adolescents on skeletal muscle lipids and glucose and insulin homeostasis. Twenty-five obese adolescents (14-17 years old, 14 females) completed a randomized double-blind crossover study supplying capsules containing either 1.2 g omega-3 LCPUFAs or placebo, for 3 months each with a six-week washout period. Fasting blood glucose, insulin, leptin, adiponectin, and lipids were measured. Intravenous glucose tolerance test (IVGTT) and euglycemic-hyperinsulinemic clamp were performed, and skeletal muscle biopsies were obtained at the end of each period. The concentrations of EPA, DHA, and total omega-3 PUFA in muscle phospholipids increased in both sexes. In the females, omega-3 LCPUFA supplementation improved glucose tolerance by 39% (P = 0.04) and restored insulin concentration by 34% (P = 0.02) during IVGTT. Insulin sensitivity improved 17% (P = 0.07). In males, none of these parameters was influenced by omega-3 supplementation. Thus, three months of supplementation of omega-3 LCPUFA improved glucose and insulin homeostasis in obese girls without influencing body weight.

- Compared to normal weight adolescents, obese adolescents have lower serum omega-3 (n-3) polyunsaturated fatty acid (PUFA) concentrations, augmented inflammatory activity and endothelial dysfunction. We wanted to assess whether n-3 supplementation increases the serum n-3 PUFA concentration, improves vascular function and morphology, and lowers inflammation in obese adolescents.

- To assess the four-year outcome in children with obesity randomised to one of two 12-month lifestyle treatment programmes in primary care.At baseline, 64 children with obesity aged 8.0-13.0 years were randomised to a treatment programme managed either by a nurse, dietician and physiotherapist (n = 32) or by a nurse and dietician (n = 32).From baseline to follow-up, the mean body mass standard deviation score (BMISDS) had decreased by -0.50 [standard deviation (SD) 0.73], p = 0.002, in the nurse, dietician and physiotherapist group (n = 27), by -0.26 (SD 0.73), p = 0.057 in the other group (n = 29); adjusted mean difference was -0.22, 95% confidence interval -0.59; 0.16, p = 0.25. Changes in weight categories did not differ between the groups: both had a change from obesity to normal weight in 1 and to overweight in 6; in the physiotherapist group 1 case of severe obesity changed to obesity. The combined treatment groups (n = 56) had a mean reduction in BMISDS of -0.37 (SD 0.73) and an improved distribution in weight categories, p = 0.015.After four years, there was no difference in outcome between the treatment options. In the treatment groups combined the number of children with obesity and their adiposity measures were significantly lower.

Tidskriftsartikel (refereegranskat)abstract
- Bariatric surgery is suggested as a treatment option for severely obese adolescents. Because adolescence is characterized by intense psychosocial adjustment and development, it is important to study the effect of this procedure on adolescents' psychological health. This study examined baseline status and short-term changes in anxiety, depression, anger, disruptive behavior, and self-concept in 37 adolescents (mean age 16.6 ± 1.3). Participants completed the Beck Youth Inventories (BYI) at inclusion and (on average) 4 months after undergoing Roux-en-Y gastric bypass (RYGB). Internalizing (anxiety and depression) and externalizing (anger and disruptive behavior) symptoms were higher at baseline than gender-specific norms. One fifth had a very low self-concept. Four months after surgery, the adolescents showed significantly fewer symptoms of anxiety and depression and significantly improved self-concept from baseline. Anger and disruptive behavior showed no significant changes. An analysis of clinically meaningful changes was conducted, and besides the overall positive outcome, 16% (n = 6) of the adolescents had deteriorated on two or more inventories in BYI shortly after surgery. This impaired group did not show any specific features at inclusion. The results indicate the importance of psychological monitoring immediately after bariatric surgery and the need for additional psychosocial support to be available for vulnerable sub-groups of adolescents. Further studies with larger samples are necessary to identify characteristics predictive of short-term adverse psychological outcomes in adolescents after bariatric surgery.
