RESUMO
OBJECTIVE: Since Cushing's disease (CD) is less common in the paediatric age group than in adults, data on this subject are relatively limited in children. Herein, we aim to share the clinical, diagnostic and therapeutic features of paediatric CD cases. DESIGN: National, multicenter and retrospective study. PATIENTS: All centres were asked to complete a form including questions regarding initial complaints, physical examination findings, diagnostic tests, treatment modalities and follow-up data of the children with CD between December 2015 and March 2017. MEASUREMENTS: Diagnostic tests of CD and tumour size. RESULTS: Thirty-four patients (M:F = 16:18) from 15 tertiary centres were enroled. The most frequent complaint and physical examination finding were rapid weight gain, and round face with plethora, respectively. Late-night serum cortisol level was the most sensitive test for the diagnosis of hypercortisolism and morning adrenocorticotropic hormone (ACTH) level to demonstrate the pituitary origin (100% and 96.8%, respectively). Adenoma was detected on magnetic resonance imaging (MRI) in 70.5% of the patients. Transsphenoidal adenomectomy (TSA) was the most preferred treatment (78.1%). At follow-up, 6 (24%) of the patients who underwent TSA were reoperated due to recurrence or surgical failure. CONCLUSIONS: Herein, national data of the clinical experience on paediatric CD have been presented. Our findings highlight that presenting complaints may be subtle in children, the sensitivities of the diagnostic tests are very variable and require a careful interpretation, and MRI fails to detect adenoma in approximately one-third of cases. Finally, clinicians should be aware of the recurrence of the disease during the follow-up after surgery.

BACKGROUND: A chronic autoimmune disease with an increasing incidence rate, type 1 diabetes mellitus (T1DM) is typified by the degeneration of the pancreatic beta cells. Diabetes management is significantly impacted by nutrition. Although it has been demonstrated that following the Mediterranean diet (MD) improves metabolic control with type 2 diabetes in children and adults, its effects on children with T1DM have not received much attention. OBJECTIVE: Therefore, the purpose of this study was to assess whether adherence to Mediterranean diet is associated with better metabolic control and body composition in youths with Type 1 Diabetes Mellitus. The study recruited T1DM patients aged 6-18 years at Istanbul University Cerrahpasa Medical Faculty Hospital's Pediatric Endocrinology and Diabetes Outpatient Clinic for follow-up. METHODS: In addition to demographic variables, some anthropometric measurements, body composition and biochemical parameters such as: Trygliceride(TG), Total cholesterol (TC), High density lipoprotein cholesterol (HDL-C), Low density lipoprotein cholesterol (LDL-C), (Aspartate aminotransferase) AST, Alanine transaminase (ALT) and glycated hemoglobin (HbA1c) was analyzed. The time in range (TIR) is a value obtained from continuous glucose monitoring. KIDMED was used to assess the participants' adherence with the MD. RESULTS: Good adherence to the MD resulted in much larger height SDS than poor adherence. Poor adherence to MD resulted in higher body fat than moderate and good adherence. There is positivite correlation between TIR and KIDMED score. Adherence to MD is negatively associated with HbA1c. The regression anaylsis showed that a one-point rise in the KIDMED score would result in a 0.314-unit reduction in the HbA1c value (p < 0.01). CONCLUSIONS: In conclusion, this study found that adhering to MD led to improved anthropometric measurements, biochemistry, and diabetes outcomes. Awareness among children, adolescents with T1DM, and their parents about the benefits of MD compliance for glycemic and metabolic control should be raised.

OBJECTIVE: 12,13-Dihydroxy-9Z-octadecenoic acid (12,13-diHOME) is a lipokine secreted from brown adipose tissue, and it has positive effects on dyslipidemia. Acute exercise has been shown to lead to an increase in its secretion. In this study, it was aimed to investigate the relationship of 12,13-diHOME with obesity, exercise and dyslipidaemia for the first time in the adolescent age group. DESIGN: Prospective study. PATIENTS: Twenty-eight male adolescents with obesity and the same number of age-matched healthy normal-weight male controls. MEASUREMENTS: Fasting serum glucose, insulin, lipid and 12,13-diHOME levels were measured. Cardiopulmonary exercise testing was performed in all subjects using a stress test treadmill. Peak oxygen consumption (peak VO2) and anaerobic threshold heart rate (ATHR) were measured. RESULTS: Adolescents with obesity had lower 12,13-diHOME levels than normal-weight adolescents both before and after acute exercise (p = .025 and p = .019, respectively), and after acute exercise, 12,13-diHOME levels significantly increased in both groups (p = .001 for both). 12,13-diHOME levels negatively correlated with triglyceride, total cholesterol, LDL-C, and positively correlated with HDL-C. Also, peak VO2 and ATHR levels showed positive correlation with 12,13-diHOME levels. CONCLUSION: 12,13-diHOME levels were found to be lower in adolescents with obesity than normal-weight adolescents and increased with acute exercise. Also, the close relationship of this molecule with dyslipidaemia in addition to that with obesity suggests that it has an important role in the pathophysiology of these disorders. Further molecular studies will further elucidate the role of 12,13-diHOME in obesity and dyslipidaemia.

Hyporeninemic hypoaldosteronism has been reported in only a few cases with methylmalonic acidemia (MMA) and has been attributed to the renal involvement. This study aims to investigate renin-aldosterone levels along with the renal functions of the patients with organic acidemia. This is a cross-sectional study conducted in patients with MMA, propionic acidemia (PA), and isovaleric acidemia (IVA). Serum renin, aldosterone, sodium, and potassium levels were measured, and glomerular filtration rates (GFR) were calculated. Comparisons were made between the MMA and non-MMA (PA+IVA) groups. Thirty-two patients (MMA:PA:IVA = 14:13:5) were included. The median GFR was significantly lower in the MMA group than in the non-MMA group (p < 0.001). MMA patients had the highest incidence of kidney damage (71.4%), followed by PA patients (23%), while none of the IVA patients had reduced GFR. GFR positively correlated with renin levels (p = 0.015, r = 0.433). Although renin levels were significantly lower in the MMA group than the non-MMA group (p = 0.026), no significant difference in aldosterone levels was found between the two groups. Hyporeninemic hypoaldosteronism was found in 3 patients with MMA who had different stages of kidney damage, and fludrocortisone was initiated, which normalized serum sodium and potassium levels. Conclusions: This study, which has the largest number of patients among the studies investigating the renin-angiotensin system in organic acidemias to date, has demonstrated that hyporeninemic hypoaldosteronism is not a rare entity in the etiology of hyperkalemia in patients with MMA, and the use of fludrocortisone is an effective treatment of choice in selected cases. What is Known: ⢠Hyperkalemia may be observed in cases of methylmalonic acidemia due to renal involvement and can be particularly prominent during metabolic decompensation. ⢠Hyporeninemic hypoaldosteronism has been reported to be associated with hyperkalemia in only a few cases of methylmalonic acidemia. What is New: ⢠Hyporeninemic hypoaldosteronism was found in one-fifth of cases with methylmalonic acidemia. ⢠Fludrocortisone therapy leads to the normalization of serum sodium and potassium levels.

PURPOSE: It was aimed to investigate the frequency of the risk of diabetes-specific eating disorder (DSED) in adolescents with type 1 diabetes mellitus (T1DM) and to reveal the accompanying psychopathologies. METHODS: Adolescents with T1DM aged 12-18 who applied to the pediatric diabetes outpatient clinic between July 2021 and March 2022 were included. Diabetes Eating Problem Survey-Revised (DEPS-R) was applied to all patients to determine the risk of DSED. In order to detect accompanying psychopathologies, Eating Disorder Examination Questionnaire (EDE-Q), Child Anxiety and Depression Scale-Child version (RCADS) and Parenting Style Scale were applied. After completing the scales, semi-structured interviews were conducted with all patients by a child and adolescent psychiatrist. RESULTS: Ninety-two adolescents (45 boys, 47 girls) were included. DSED risk was found in 23.9% of the cases. A positive correlation was found between DEPS-R and EDE-Q scores (p = 0.001, rho = 0.370). RCADS mean scores were significantly higher in the group with DSED risk (p < 0.001). When the Parenting Style Scale was evaluated, psychological autonomy scores were significantly lower in the group with DSED risk (p = 0.029). As a result of the psychiatric interviews, 30 (32.6%) patients had at least 1 psychiatric disorder. Of these, 2 patients were diagnosed with eating disorder. CONCLUSION: Almost one-fourth of adolescents with T1DM were found to be at risk of DSED. Routine screening of adolescents with T1DM with the DEPS-R scale may provide early detection of DSED, and referral of those at risk to child psychiatry enables early diagnosis and intervention for both eating disorders and accompanying psychopathologies. LEVEL OF EVIDENCE: Level III: Evidence obtained from cohort or case-control analytic studies.

BACKGROUND: In this study, eating behaviors and alexithymia levels in obese adolescents were investigated. Relationships between alexithymia, eating behavior and insulin resistance were studied. METHODS: The patient group consisted of 87 obese adolescents or overweight adolescents (O + OW). The comparison group consisted of 101 normal weight adolescents (N). Alexithymia Questionnaire for Children, Dutch Eating Behavior Questionnaire, and Revised Child Anxiety and Depression Scale-Child Version, are used for assessing adolescents. The homeostasis model assessment-estimated insulin resistance was calculated to determine insulin resistance. RESULTS: Alexithymia Questionnaire for Children scores were significantly higher in O + OW than N (P = 0.009). Both emotional and restrained eating scores are higher in O + OW (P < 0.001 for both). On the other hand, external eating scores were not significantly different. In O + OW, external eating was positively associated with homeostasis model assessment-estimated insulin resistance (r: 035, P = 0.006), but is not associated with fasting blood glucose and the hemoglobin A1c (HbA1c) (r: -0.05, P = 0.62; r: -0.05, P = 0.73). Regression analysis showed that restrained and emotional eating were predictors of O + OW (B: 0.1, P < 0.001; B: 0.06, P = 0.001). Emotional eating was positively correlated with the Alexithymia Questionnaire for Children and Revised Child Anxiety and Depression Scale-Child Version in O + OW (r: 0.29, P = 0.008; r: 0.48, P < 0.001). CONCLUSIONS: Obese and overweight adolescents were more alexithymic than normal weight adolescents. Alexithymia scores were also positively associated with emotional eating. On the other hand, alexithymia was not a predictor of obesity/overweight. Restrained and emotional eating were predictors of obesity/overweight. Emotional and restrained eating were more common in obese and overweight adolescents than normal-weight adolescents. External eating is not significantly associated with obesity but is related to insulin resistance.

BACKGROUND: Hypothyroxinemia is defined by low levels of thyroxine (T4) despite low or normal levels of thyroid-stimulating hormone (TSH). This study aimed to evaluate the factors associated with transient hypothyroxinemia of prematurity (THOP) in newborns admitted to the neonatal intensive care unit (NICU). METHOD: This is a single center, retrospective, case-control study. Premature newborns, between 24 and 34 weeks of gestation, hospitalised between January 2014-December 2019 in Istanbul University-Cerrahpasa Faculty of Medicine NICU were analyzed through their medical records. Thyroid function tests were routinely performed between the 10th and 20th days of postnatal life and were evaluated according to the gestational age references. Thirty six possible associated factors (prenatal and postnatal parameters, medical treatments, clinical diagnoses and applications in NICU) were searched in the patient group with THOP (n = 71) and the control group with euthyroid prematures (n = 73). The factors for THOP were identified by univariate analysis, followed by multivariate analysis. RESULTS: Mean gestational ages of the study and the control groups were 29.7 ± 2.48 and 30.5 ± 2.30 weeks, respectively (p = 0.606). The birth weight, small for gestational age (SGA), intraventricular hemorrhage (IVH), congenital heart disease (CHD) were found to be the possible associated factors for THOP in the univariate analysis and CHD (p = 0.007, odds ratio [OR]:4.9, 95% confidence interval [CI]: 1.5-15.8), BW (p = 0.004, OR:0.999, 95% CI: 0.9-1.0) and SGA (p = 0.010, OR:4.6, 95% CI: 1.4-14.7) were found to be factors associated with THOP determined by univariate logistic regression analysis. CONCLUSiONS: Although some treatment practices might have had direct effects on pituitary-thyroid axis, related with the severity of the newborn clinical conditions, non of them was found to be a associated factor for THOP. However, CHD and SGA may be considered as associated factors with THOP detected in preterm infants.

BACKGROUND: The aim of the study is to identify the effect of salt intake and diabetes itself on blood pressure (BP) profile and microalbuminuria in children with type one diabetes mellitus (T1DM). Our hypothesis is that higher amount of salt consumption and/or hyperglycemia may impair blood pressure pattern in children with T1DM. METHODS: This cross-sectional study included 84 children and adolescents with T1DM (62% females, age 13.9 ± 3.2 years, disease duration 7.3 ± 3.1 years, 43% poorly controlled diabetes) and 54 aged- and sex-matched healthy children with an adequately collected 24-h urine samples. Urine sodium, creatinine, and microalbumin were measured and salt intake was assessed on the basis of sodium excretion in 24-h urine. Blood pressure profile of the children with T1DM was evaluated with 24-h ambulatory blood pressure monitoring. RESULTS: Compared to the children with well-controlled diabetes, children with poorly controlled diabetes had significantly higher standard deviation scores (SDS) of nighttime systolic BP (0.22 ± 1.28 vs - 0.87 ± 0.76, p = 0.003) and lower dipping in diastole (13.4 ± 5.9 vs 18.4 ± 8.1, p = 0.046). Among T1DM group, children with the highest quartile of salt intake had higher nighttime systolic and diastolic BP-SDS (0.53 ± 1.25 vs - 0.55 ± 0.73, p = 0.002 and 0.89 ± 1.19 vs 0.25 ± 0.63, p = 0.038, respectively) and lower dipping in systole compared to their counterparts (7.7 ± 5.0 vs 11.5 ± 6.1, p = 0.040). High averaged HbA1c was independently associated with higher both daytime and nighttime systolic BP-SDS (p = 0.010, p < 0.001) and nighttime diastolic BP-SDS (p = 0.001), and lower diastolic dipping (p = 0.001). High salt intake was independently associated with higher nighttime systolic BP-SDS (p = 0.002) and lower systolic dipping (p = 0.019). A 24-h MAP-SDS was the only independent risk factor for microalbuminuria (p = 0.035). CONCLUSION: Beside poor diabetic control, high salt consumption appears to be an important modifiable risk factor for impaired BP pattern, which contributes to the development of diabetic kidney disease in children with T1DM.

BACKGROUND: The determination of the protective and risk factors associated with Internet gaming disorder (IGD) is among the most important pathways to the development of prevention strategies for IGD. Previous research has shown that familial factors are associated with IGD. In our study, we aimed to assess the parental attitude of adolescents with IGD and investigate psychiatric comorbidity. METHODS: We assessed family structure, family relationship, parental attitude (in a bi-directional assessment), and psychiatric comorbidity in 50 adolescents aged 12-18 years who meet DSM-5 criteria for IGD in comparison with the control group. Parental attitudes were assessed with the Parental Attitude Research Instrument (filled by the mother) and the Parenting Style Inventory (filled by adolescents). RESULTS: Our findings suggest that according to mothers' opinions there were no significant differences in the subscale scores between the IGD group and the control group. On the other hand, acceptance-involvement and psychological autonomy subscale scores of the PSI filled by adolescents were found to be significantly lower in the IGD group. Limit setting in areas other than the Internet was significantly lower in the IGD group. High rates of psychiatric comorbidity were also found in adolescents with IGD. CONCLUSIONS: Our study identified that adolescents with IGD perceived their parents "cared less about them" and "minded less on their autonomy" compared with the control group. Our survey demonstrated that parental attitudes may be among the risk factors for IGD and the presence of psychiatric comorbidity may affect the management of IGD.

Congenital adrenal hyperplasia (CAH) is an autosomal recessive genetic disorder due to presence of mutations in the genes involved in the metabolism of steroid hormones in adrenal gland. There are two main forms of CAH, classic form and non-classic form. While classic form stands for the severe form, the non-classic form stands for the moderate and more frequent form of CAH. The enzyme deficiencies such as 21-hydroxylase, 11-beta-hydroxylase, 3-beta-hydroxysteroid dehydrogenase, 17-alpha-hydroxylase deficiencies are associated with CAH. In this study, we aimed to investigate CYP21A2, CYP11B1, HSD3B2 genes which are associated with 21-hydroxylase, 11-beta-hydroxylase and 3-beta-hydroxysteroid dehydrogenase enzyme deficiencies, respectively, in 365 individuals by using Sanger sequencing method. We emphasized the classification of variants according their disease causing potential, and evaluated variants' frequencies including newly discovered novel variants. As a result, 32 variants of CYP21A2 including 10 novel variants, 9 variants of CYP11B1 including 3 novel variants and 6 variants of HSD3B2 including 4 novel variants were identified. The conclusions of our study showed that in Anatolia, discovery of novel variants is quite common on account of tremendous ratios of consanguineous marriages which increases the frequency of CAH. These results will contribute to the understanding of molecular pathology of the disease.

AIM: Pituitary adenomas are rare in childhood in contrast with adults. Adrenocorticotropic hormone (ACTH)-secreting adenomas account for Cushing's disease (CD) which is the most common form of ACTH-dependent Cushing's syndrome (CS). Treatment strategies are generally based on data of adult CD patients, although some difficulties and differences exist in pediatric patients. The aim of this study is to share our experience of 10 children and adolescents with CD. PATIENTS AND METHOD: Medical records, images, and operative notes of 10 consecutive children and adolescents who underwent transsphenoidal surgery for CD between 1999 and 2014 in Cerrahpasa Faculty of Medicine were retrospectively reviewed. Mean age at operation was 14.8 ± 4.2 years (range 5-18). The mean length of symptoms was 24.2 months. The mean follow-up period was 11 years (range 4 to 19 years). RESULTS: Mean preoperative cortisol level was 23.435 µg/dl (range 8.81-59.8 µg/dl). Mean preoperative ACTH level was 57.358 µg/dl (range 28.9-139.9 µg/dl). MR images localized microadenoma in three patients (30%), macroadenoma in four patients (40%) in our series. Transsphenoidal microsurgery and endoscopic transsphenoidal surgery were performed in 8 and 2 patients respectively. Remission was provided in 8 patients (80%). Five patients (50%) met remission criteria after initial operations. Three patients (30%) underwent additional operations to meet remission criteria. CONCLUSION: Transsphenoidal surgery remains the mainstay therapy for CD in pediatric patients as well as adults. It is an effective treatment option with low rate of complications. Both endoscopic and microscopic approaches provide safe access to sella and satisfactory surgical results.

Homosalate (HMS) and 2-ethylhexyl 4-dimethylaminobenzoate (OD-PABA) are ultraviolet filters. We aimed to investigate the effects of dermal exposure to HMS and OD-PABA during the prenatal, lactation, and early infancy periods on pubertal development and thyroid function in male and female rats. The thyroid glands, uteri, testes, prostate glands, and seminal vesicles were excised and weighed, the reproductive organs were analyzed histologically, and the serum hormone levels were measured. In the prenatal period, the thyroxine (T4) levels increased in the female rats in the exposed groups ( p < 0.05); the thyroid weights, reproductive organ weights, and gonadal hormone levels were not altered. In males, the testosterone levels decreased ( p < 0.05), but the thyroid weights, T4 levels, prostate, and testis weights were not changed. In the lactation period, the weights of the thyroid glands increased in the exposed female groups ( p < 0.05), but the T4, gonadal hormone levels, and reproductive organ weights were not changed. In the males, the thyroid gland weights, T4 levels, reproductive organ weights, and gonadal hormone levels were not changed. During infancy, the thyroid gland weights increased in the female rats in the exposed groups ( p < 0.05), but the T4 levels, gonadal hormone levels, and reproductive organ weights were not affected. In the male rats in the exposed groups, the T4 levels were increased ( p < 0.05), but the thyroid and reproductive organ weights, gonadal hormone levels were not affected. Organ histopathology was not affected in all groups. HMS and OD-PABA do not have endocrine disruptor effects on thyroid function and the pubertal development of female and male rats.

To evaluate the anthropometric features of girls with Turner syndrome (TS) at birth and presentation and the effect of karyotype on these parameters. Data were collected from 842 patients with TS from 35 different centers, who were followed-up between 1984 and 2014 and whose diagnosis age ranged from birth to 18 years. Of the 842 patients, 122 girls who received growth hormone, estrogen or oxandrolone were excluded, and 720 girls were included in the study. In this cohort, the frequency of small for gestational age (SGA) birth was 33%. The frequency of SGA birth was 4.2% (2/48) in preterm and 36% (174/483) in term neonates (P < 0.001). The mean birth length was 1.3 cm shorter and mean birth weight was 0.36 kg lower than that of the normal population. The mean age at diagnosis was 10.1 ± 4.4 years. Mean height, weight and body mass index standard deviation scores at presentation were -3.1 ± 1.7, -1.4 ± 1.5, and 0.4 ± 1.7, respectively. Patients with isochromosome Xq were significantly heavier than those with other karyotype groups (P = 0.007). Age at presentation was negatively correlated and mid-parental height was positively correlated with height at presentation. Mid-parental height and age at presentation were the only parameters that were associated with height of children with TS. The frequency of SGA birth was found higher in preterm than term neonates but the mechanism could not be clarified. We found no effect of karyotype on height of girls with TS, whereas weight was greater in 46,X,i(Xq) and 45,X/46,X,i(Xq) karyotype groups.

BACKGROUND: The purpose of this study was to assess recent changes in the prevalence of overweight (including obesity) among 11-, 13- and 15-year-olds in 33 countries from 2002 to 2010. METHODS: Data from 25 countries from three consecutive survey cycles (2002, 2006 and 2010) that had at least 80% response rate for self-reported height, weight and age were analysed using logistic regression analysis. RESULTS: Overweight prevalence increased among boys in 13 countries and among girls in 12 countries; in 10 countries, predominantly in Eastern Europe, an increase was observed for both boys and girls. Stabilization in overweight rates was noted in the remaining countries; none of the countries exhibited a decrease over the 8-year period examined. In the majority of countries (20/25) there were no age differences in trends in overweight prevalence. CONCLUSION: In over half of the countries examined overweight prevalence did not change during 2002-2010. However, increasing overweight prevalence was noted in many Eastern European countries over this time period. Overweight prevalence remained high in several countries in Europe and North America. These patterns call for continued research in youth overweight and highlight the need to understand cross-national differences by examining macro-level indicators. Such research should feed into developing sound translations and practices to prevent and reduce overweight in youth.

Anxiety comorbidity is quite common in children with attention-deficit hyperactivity disorder (ADHD). What is known about the relationship between anxiety, attachment and emotion regulation in such children is still limited. We aimed to investigate the associations between attachment, emotion regulation and comorbid anxiety in children with ADHD. 100 children with ADHD and 100 children without any diagnosis aged 8-13 years were included. After the participants were clinically evaluated, Turgay ADHD Scale, Emotion Regulation Checklist, Revised Child Anxiety and Depression Scale-Child Version (RCADS-CV) and Kerns' Security Scale were completed. According to the RCADS-CV scores, ADHD/ANX(+), ADHD/ANX(-), and control groups were formed. The emotional lability/negativity levels were higher in the ADHD groups compared to the non-ADHD controls. Paternal and maternal attachment security levels were lower in the ADHD/ANX(+) group compared to the controls. The regression analysis indicated that higher hyperactivity/impulsivity symptom levels and lower maternal attachment quality were associated with higher anxiety in children with ADHD. These results suggest that focusing on attachment quality and emotion regulation problems may be significant in management of core symptoms and comorbid anxiety problems in children with ADHD.

Objectives: We report a patient with papillary thyroid carcinoma (PTC) who developed acute kidney injury (AKI) and elevated creatine kinase (CK) after thyroid hormone withdrawal (THW) prior to radioiodine therapy. Case presentation: A 12-year-old female patient who had undergone total thyroidectomy for PTC one year ago presented with leg pain for the past 2 days. Following THW 3 weeks ago, the case had received 70 mCI radioiodine treatment 6 days ago. Serum creatinine (1.53 mg/dL, normal range [NR]: 0.3-1.1), aspartate aminotransferase (102 IU/L, NR: 0-40) and CK (3451 IU/L, NR: 26-174) levels were elevated. Thyrotropin level was elevated (>100 µIU/ml, NR: 0.51-4.3), and free T4 level was decreased (0.05 ng/dL, NR: 0.98-1.63). Serum creatinine and CK levels decreased after intravenous hydration and levothyroxine treatment. Conclusion: In PTC cases with thyroidectomy, kidney function and CK elevation should be assessed after THW and dehydration should be prevented.
RESUMO
Objectives: Social media has become integrated into adolescents' lives and influences body image perceptions. Our study examined four patterns of social media use (SMU): non-active, active, intensive, and problematic. We hypothesised that intensive SMU and problematic SMU would be associated with negative body image (negative subjective body weight) and over/underestimated body weight congruence, compared to non-active and active SMU. In addition, we expect these associations to be stronger for girls. Methods: Data from 190,892 respondents aged 11, 13, and 15 from 42 countries involved in the Health Behaviour in School-aged Children study were analysed. Results: Findings revealed higher rates of intensive or problematic SMU among adolescents who perceived themselves as too fat or too thin. Two-level regression analyses showed intensive and problematic SMU as more likely to perceive themselves as too fat or too thin than active users. The association was significant among intensive and problematic girl social media users, whereas, among boys, the relationship was only significant for problematic users. Conclusion: Our findings highlight the importance of assessing SMU patterns to evaluate associations with body image.
