Do adolescents with extreme obesity differ according to previous treatment seeking behavior? The Youth with Extreme obesity Study (YES) cohort.

OBJECTIVES: Adolescent extreme obesity is associated with somatic and psychiatric comorbidity, low quality of life, and social dysfunction. Nevertheless, few adolescents seek obesity treatment, thus many may elope appropriate care. We examine whether previous treatment seeking relates to disease burden, and whether previously non-treatment seeking adolescents accept diagnostic and therapeutic offers. This information is important to inform intervention strategies. METHODS: The Youth with Extreme obesity Study (YES) is a prospective, multicenter cohort study. We developed a novel recruitment strategy to span medical and vocational ascertainment settings and directly compare previously treatment seeking and non-treatment seeking youth. Participants aged 14-24 years; BMI ≥ 30 kg/m2 were enrolled at four medical- and one job centers. We present comorbidity and psycho-social baseline data by sex, obesity WHO grade I-III, and treatment-seeking status, defined as self-reported previous participation in a weight-loss program. RESULTS: Of 431 participants, 47% were male; mean age 16.6 (standard deviation 2.3) years, BMI 39.2 (7.5) kg/m2. Somatic comorbidity increased with obesity grade, p < 0.05: hypertension (42, 55, 64%), dyslipidemia (28, 24, 37%,), dysglycemia (9, 19, 20%,), elevated transaminases (15, 26, 30%). Quality of life (EQ5 D) decreased (74, 71, 70). Rates of psychiatric disorders were stable: depression 11%, attention deficit disorder 6%, substance use disorder 2%, self-injurious behavior 5%, suicide attempt 3%. Only 63% (56, 64, 69%) reported previous treatment seeking. Acceptance of the diagnostic (89%) or therapeutic (28%) program, medical or psychosocial situation did not differ by treatment seeking status. Acceptance of the therapeutic program was generally low, but high at the job center (92%). CONCLUSION: Irrespective of previous treatment seeking, adolescent extreme obesity was associated with high comorbidity and psychosocial burden. Acceptance of the diagnostic program overall and the therapeutic program at the job center were high. This underscores the need of innovative, accessible programs beyond the currently offered care.

Genome-wide association study of sexual maturation in males and females highlights a role for body mass and menarche loci in male puberty.

Little is known about genes regulating male puberty. Further, while many identified pubertal timing variants associate with age at menarche, a late manifestation of puberty, and body mass, little is known about these variants' relationship to pubertal initiation or tempo. To address these questions, we performed genome-wide association meta-analysis in over 11 000 European samples with data on early pubertal traits, male genital and female breast development, measured by the Tanner scale. We report the first genome-wide significant locus for male sexual development upstream of myocardin-like 2 (MKL2) (P = 8.9 × 10(-9)), a menarche locus tagging a developmental pathway linking earlier puberty with reduced pubertal growth (P = 4.6 × 10(-5)) and short adult stature (p = 7.5 × 10(-6)) in both males and females. Furthermore, our results indicate that a proportion of menarche loci are important for pubertal initiation in both sexes. Consistent with epidemiological correlations between increased prepubertal body mass and earlier pubertal timing in girls, body mass index (BMI)-increasing alleles correlated with earlier breast development. In boys, some BMI-increasing alleles associated with earlier, and others with delayed, sexual development; these genetic results mimic the controversy in epidemiological studies, some of which show opposing correlations between prepubertal BMI and male puberty. Our results contribute to our understanding of the pubertal initiation program in both sexes and indicate that although mechanisms regulating pubertal onset in males and females may largely be shared, the relationship between body mass and pubertal timing in boys may be complex and requires further genetic studies.

Reciprocal Associations between Electronic Media Use and Behavioral Difficulties in Preschoolers.

The use of electronic media has increased substantially and is already observable in young children. The present study explored associations of preschoolers’ use of electronic media with age, gender, and socio-economic status, investigated time trends, and examined reciprocal longitudinal relations between children’s use of electronic media and their behavioral difficulties. The study participants included 527 German two- to six-year-old children whose parents had provided information on their use of electronic media and their behavioral difficulties at two time points, with approximately 12 months between baseline and follow-up. The analyses revealed that older vs. younger children, as well as children from families with a lower vs. higher socio-economic status, were more often reported to use electronic media. Furthermore, the usage of mobile phones increased significantly between 2011 and 2016. Most interestingly, baseline usage of computer/Internet predicted more emotional and conduct problems at follow-up, and baseline usage of mobile phones was associated with more conduct problems and hyperactivity or inattention at follow-up. Peer relationship problems at baseline, on the other hand, increased the likelihood of using computer/Internet and mobile phones at follow-up. The findings indicate that preschoolers’ use of electronic media, especially newer media such as computer/Internet and mobile phones, and their behavioral difficulties are mutually related over time.

A Structured, Manual-Based Low-Level Intervention vs. Treatment as Usual Evaluated in a Randomized Controlled Trial for Adolescents with Extreme Obesity - the STEREO Trial.

BACKGROUND: To compare efficacy and safety of a manual-based low-level psychological intervention with treatment as usual (weight loss treatment). METHODS: A two-armed randomized controlled trial without blinding and computer-based stratified block randomization included adolescents and young adults (14.0-24.9 years) with a BMI ≥ 30 kg/m2 at five German university hospitals. Primary outcomes were adherence (participation rate ≥ 5/6 sessions) and quality of life (DISABKIDS-37) 6 months after randomization. Secondary outcomes included depression, self-esteem, and perceived stress scores. RESULTS: Of 397 screened adolescents, 119 (mean BMI 40.4 ± 7.0 kg/m2, 49.6% female) were randomized to the manual-based low-level intervention (n = 59) or treatment as usual (n = 60). We observed no group difference for adherence (absolute risk reduction 0.4%, 95% CI -14.7% to 15.5%; p = 1.0) or health-related quality of life (score difference 8.1, 95% CI -2.1 to 18.3; p = 0.11). Among all secondary outcomes, we detected explorative evidence for an effect on the DISABKIDS-37 'social exclusion' subscale (score difference 15.5; 95% CI 1.6-29.4; p = 0.03). 18/19 adverse events occurred in 26 participants, none were classified as serious. CONCLUSION: Adherence to a coping-oriented intervention was comparable to weight loss treatment, although it was weak in both interventions. Psychological interventions may help to overcome social isolation; further confirmation is required.

Perception of body weight status: a case control study of obese and lean children and adolescents and their parents.

BACKGROUND: The objective of this study was to investigate differences in weight perception and self-concept of obese and lean children, and to examine parents' awareness of overweight in themselves and their children. A total of 59 obese patients aged 7-17 years and 49 of their parents from a pediatric obesity out-patient clinic participated and were compared with 96 normal-weight patients and 81 of their parents from a pediatric pulmonary disease out-patient clinic. METHODS: Children's and parents' self-perception of weight, desire for weight change and weight concerns, children's belief that their desired weight can be achieved, and parents' perception of their child's weight status were assessed using single questionnaire items. Children's self-concept was measured by the Self-Perception Profile for Children. In addition, children drew pictures about themselves and their favorite activity. RESULTS: Obese patients wished to change their weight more frequently (p < 0.001) and had more weight concerns (p < 0.001). Their self-concept was significantly more negative. Physical activities were more common in their drawings than in those of normal-weight peers. Parents of obese children were more frequently overweight or obese themselves (p < 0.001). 35 of them and 73 parents of normal-weight children perceived their own weight realistically. Of the parents with overweight or obese children, 69.4% perceived their own child as overweight and 28.6% as very overweight, whereas 83% of them were obese. CONCLUSION: Children and adolescents as well as their parents recognize overweight as a health problem. In the majority, weight perception matches real body weight. Most parents at least recognize overweight in their children.
