Abstract
PURPOSE The United States Preventative Services Task Force found insufficient evidence to support universal screening for eating disorders (EDs) but did recommend assessing high-risk adolescents through laboratory tests, close follow-up, and referrals to other specialties. Yet, it is unclear whether youth at high risk for EDs receive such assessment and whether patient characteristics influence such practices. METHODS Using the Rochester Epidemiological Project, we identified adolescents (13-18 years) at risk for EDs (i.e., weight loss, underweight, or loss of appetite not explained by a medical condition) who presented for a medical appointment between January 1, 2005 to December 31, 2017 (n = 662; M age = 15.8 years; 66% female; 76% white). Patient and visit characteristics, assessment practices (i.e., tests, referrals, and follow-up), and ED diagnoses within 5 years following index visit were extracted. RESULTS Adolescents who received referrals to other providers were 4 times more likely to be diagnosed with a future ED (p < .001) and were diagnosed 137.8 days sooner (Est = -137.8, p = .04) compared to those who did not receive referrals. Compared to males, females were 2.2 times more likely to receive referrals (p < .001). Compared to those presenting at a lower body mass index, adolescents with a higher body mass index were more likely to receive medical tests (HR = 1.0, p < .01) and less likely to receive recommendations to improve eating/weight (HR = 0.99, p < .01) or follow up visits (HR = 0.99, p < .01). DISCUSSION Disparities in assessment practices for adolescents at high-risk for EDs underscore the need for improved tools to enhance early detection and treatment.

Abstract
IMPORTANCE Despite high use of smartphones among adolescents, little is known about the association of smartphone use with body image and related behaviors. OBJECTIVE To examine the associations of duration of smartphone use and types of content most frequently accessed via smartphone with body image distortion and weight loss behaviors in adolescents. DESIGN, SETTING, AND PARTICIPANTS This cross-sectional study used data from the population-based Korea Youth Risk Behavior Web-Based Survey 2017. Participants comprised a nationally representative sample of 53 133 Korean adolescents aged 12 to 18 years. Data were collected from June 1 to July 18, 2017. The analysis was performed from February 7, 2020, to March 30, 2022. EXPOSURES Self-reported duration of smartphone use (min/d) and types of content (educational or informational searches; chatting, messaging, or email; social networking services or forums; games; videos, movies, or music; webtoons or web novels; and shopping or other activities) most frequently accessed during smartphone use. MAIN OUTCOMES AND MEASURES Body image distortion (overperception of body weight), weight loss attempt, use of inappropriate weight loss strategies (skipping meals, eating only 1 food at a time, vomiting, or using laxatives), and healthy weight loss behaviors (muscle-strengthening and aerobic physical activity). Multivariable logistic regression analysis was performed to estimate odds ratios (ORs) and 95% CIs, accounting for survey sampling and adjusting for potential confounders. RESULTS Among 53 133 participants, the mean (SD) age was 15.0 (1.8) years; 50.7% of participants were female, and 49.3% were male. After adjusting for types of content accessed, prolonged smartphone use (≥301 min/d) was positively associated with body image distortion (boys: OR, 1.17; 95% CI, 1.07-1.28; girls: OR, 1.20; 95% CI, 1.10-1.30) and inappropriate weight loss strategies (boys: OR, 1.54; 95% CI, 1.25-1.90; girls: OR, 2.45; 95% CI, 2.14-2.79) in both sexes compared with minimal smartphone use (1-120 min/d). After adjusting for duration of smartphone use, the use of smartphones mainly for videos, movies, or music (OR, 1.15; 95% CI, 1.02-1.29), webtoons or web novels (OR, 1.28; 95% CI, 1.10-1.48), and games (OR, 1.17; 95% CI, 1.03-1.32) was positively associated with body image distortion in boys compared with the use of smartphones mainly for educational or informational content. Among boys, the use of smartphones mainly for chatting, messaging, or email was positively associated with muscle-strengthening activity (OR, 1.31; 95% CI, 1.18-1.44) and aerobic physical activity (OR, 1.41; 95% CI, 1.29-1.55), as was the use of smartphones mainly for social networking services or forums (muscle-strengthening activity: OR, 1.27; 95% CI, 1.13-1.42; aerobic physical activity: OR, 1.28; 95% CI, 1.15-1.43). Among girls, the use of smartphones mainly for chatting, messaging, or email was positively associated with weight loss attempts (OR, 1.34; 95% CI, 1.19-1.51) and the use of inappropriate weight loss strategies (OR, 1.57; 95% CI, 1.25-1.99), as was the use of smartphones mainly for social networking services or forums (weight loss attempts: OR, 1.20; 95% CI, 1.07-1.36; use of inappropriate weight loss strategies: OR, 1.37; 95% CI, 1.08-1.73). CONCLUSIONS AND RELEVANCE In this cross-sectional study, both the duration of smartphone use and the types of content most frequently accessed via smartphone were associated with body image distortion and weight loss behaviors in adolescents. These findings suggest a need for the identification of strategies to help adolescents develop healthy smartphone use behaviors.

Psychological Aspects of Treatment with Intragastric Balloon for Management of Obesity: A Systematic Review of the Literature. Obes Facts 2022; 15:1-18. [PMID: 34818229 PMCID: PMC8820150 DOI: 10.1159/000518200] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2021] [Accepted: 06/24/2021] [Indexed: 11/19/2022] Open
Abstract
INTRODUCTION Optimizing maintenance of weight loss for people with obesity following intragastric balloon (IGB) therapy hinges on the degree to which health care providers can recognize both the impact of emotional problems and mood difficulties on their capacity to self-manage, and requirements for additional support. However, there is limited research on the psychological correlates of IGB therapy. This systematic review, for the first time, attempts to identify and synthesize the empirical evidence for the reciprocal influence between psychological variables and IGB outcomes. METHODS A literature search was performed in the PubMed, SCOPUS, MEDLINE, and Google Scholar databases. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed using rigorous inclusion criteria and screening by at least 2 reviewers. The selected articles were assessed for quality using the Strengthening the Reporting of Observational Studies Epidemiology (STROBE) checklist. Data were extracted to address the review aims and presented as a narrative synthesis. The review protocol was preregistered (Prospero CRD42019121291). RESULTS A total of 16,179 titles, 14,369 abstracts, and 51 full-text articles were screened, of which 16 studies were included. Findings suggest that female gender, older age, basic educational level, and single/divorced civil status, together with lower levels of depression, binge eating, higher perceived quality of life, and motivation to change were predictors of enhanced IGB treatment outcomes. Dissatisfaction with treatment was higher in those with impaired obesity-related social-life difficulties. The IGB treatment was effective in reducing weight and improving depression, anxiety, eating disorder symptoms, and the overall life quality of patients with obesity - mainly within 6 months from the device positioning and in conjunction with conventional therapies. DISCUSSION/CONCLUSION In line with the available literature on obesity and bariatric surgery interventions, poor mental health appears to be an important barrier for successful weight loss among patients with obesity undergoing IGB treatment. In order to improve the efficacy and effectiveness of the IGB therapy, more comprehensive and standardized studies are needed to provide insight into the psychological mechanisms maintaining weight management issues.

Lifestyle Genom 2020; 14:20-29. [PMID: 33302275 DOI: 10.1159/000511333] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2020] [Accepted: 08/31/2020] [Indexed: 11/19/2022] Open
Abstract
INTRODUCTION Obesity results from an imbalance in the intake and expenditure of calories that leads to lifestyle-related diseases. Although genome-wide association studies (GWAS) have revealed many obesity-related genetic factors, the interactions of these factors and calorie intake remain unknown. This study aimed to investigate interactions between calorie intake and the polygenic risk score (PRS) of BMI. METHODS Three cohorts, i.e., from the Korea Association REsource (KARE; n = 8,736), CArdioVAscular Disease Association Study (CAVAS; n = 9,334), and Health EXAminee (HEXA; n = 28,445), were used for this study. BMI-related genetic loci were selected from previous GWAS. Two scores, PRS, and association (a)PRS, were used; the former was determined from 193 single-nucleotide polymorphisms (SNPs) from 5 GWAS datasets, and the latter from 62 SNPs (potentially associated) from 3 Korean cohorts (meta-analysis, p < 0.01). RESULTS PRS and aPRS were significantly associated with BMI in all 3 cohorts but did not exhibit a significant interaction with total calorie intake. Similar results were obtained for obesity. PRS and aPRS were significantly associated with obesity but did not show a significant interaction with total calorie intake. We further analyzed the interaction with protein, fat, and carbohydrate intake. The results were similar to those for total calorie intake, with PRS and aPRS found to not be associated with the interaction of any of the 3 nutrition components for either BMI or obesity. DISCUSSION The interaction of BMI PRS with calorie intake was investigated in 3 independent Korean cohorts (total n = 35,094) and no interactions were found between PRS and calorie intake for obesity.

Abstract
Background The amount of literature shedding light upon eating disorders in developing countries, such as Pakistan, is scarce. This is partially because talking about such matters is considered taboo in the general population. Night Eating Syndrome’s (NES) link with depression and obesity has been established; however, presently, no study has been conducted which solely focuses on NES’s correlation with self-esteem. Therefore, to bridge this knowledge gap, we conducted this study to assess the prevalence of NES in Karachi and its association with self-esteem. Methods We conducted a cross-sectional study in August 2018 using convenience sampling in 395 individuals, out of which 197 belonged to the age group 18-24 and 198 to 25-30. The participants were interviewed for their gender, body mass index (BMI), and their level of education. The participants were asked to complete a structured, standardized questionnaire assessment, which comprised of questions from the Night Eating Questionnaire (NEQ) and Rosenberg Self-Esteem scale (RSE). The eating habits of the participants and the level of self-esteem were assessed using four- and five-point Likert scales. Kruskal-Wallis and chi-square tests were used as the primary statistical tests. Results Out of the 395 respondents, more than half of the respondents were females (n = 235/395, 59.5%). About one-fourth (n = 92/395, 23.3%) of the participants had a BMI of greater than 25.0 kg/m2. More than one-third of the underweight (n = 20/55, 36.4%) and overweight population (n = 33/92, 35.9%) had low self-esteem, while more than one-fourth (n = 25/92, 27.2%) of the overweight participants fulfilled the criteria of NES. The final outcomes showed that 14.4% of the participants had NES, and 4.6% of the participants had low self-esteem. Conclusion Our results pointed out to a significant relationship between NES and self-esteem. Furthermore, NES and self-esteem also had a significant association with age, gender, and BMI. Additionally, awareness regarding eating and mental disorders should be done in countries like Pakistan, where talking in regard to such matters is considered taboo. Given the various factors that further strengthen the positive relationship between NES and low self-esteem, these factors can be the targets on which the treatment can be focused.

Abstract
BACKGROUND Recent studies have associated positive emotions with several variables such as learning, coping strategies or assertive behaviour. The concept of gratitude has been specifically defined as a tendency to recognise and respond to people or situations with grateful emotion. Unfortunately in Latin America, no validated measures of gratitude on different populations are available. The aim of this study was to analyse the psychometric properties of the Gratitude Questionnaire (GQ-6) in two Chilean samples. METHODS Two studies were conducted: the first with 668 high school adolescents (390 women and 278 men, with ages ranging between 12 and 20, and a mean age 15.54 ± 1.22) and the second with 331 adults (231 women and 100 men, with an average age of 37.59 ± 12.6). An analysis of the psychometric properties of the GQ-6 scale to determine the validity and reliability of the instrument in Chilean adolescents and adults was performed. Bivariate correlations, multiple regression analyses, exploratory factor analysis (EFA) and Monte Carlo simulations were carried out. Finally, a confirmatory factor analysis (CFA) was performed. RESULTS A single-factor solution was found in both studies, a 5 item version for the adolescents and 6 items for adults. This factorial solution was invariant across genders. Reliability of the GQ was adequate in both samples (using Cronbach's alpha coefficient). In addition convergent and discriminate validity were assessed. Additionally, a negative correlation between the GQ-5 and depression in adolescents and a positive correlation between the GQ-6 and happiness in adults was found. CONCLUSIONS The GQ is a suitable measure for evaluating a person's disposition toward gratitude in Chilean adolescents and adults. This instrument may contribute to the advancement of the study of positive emotions in Latin America.

Abstract
BACKGROUND Myotubularin-related protein 14 (MTMR14) is a novel phosphoinositide phosphatase with roles in the maintenance of normal muscle performance, autophagy, and aging in mice. Our initial pilot study demonstrated that MTMR14 knock out (KO) mice gain weight earlier than their wild-type (WT) littermates, which suggests that this gene may also be involved in metabolism regulation. RESULTS The present study evaluated the role of MTMR14 in the development of aging-associated obesity. We found that aged MTMR14 KO mice fed a normal chow diet exhibited increased serum triglyceride, total cholesterol, and glucose levels compared to age-matched WT controls. Lipid accumulation was also increased in aged KO mice. Several inflammatory cytokines and adipokines were dramatically dysregulated in the metabolic tissues of aged MTMR14 KO mice compared to control mice. Circulating inflammatory cytokines were significantly elevated and plasma adipokine levels were abnormally regulated in aged MTMR14 KO mice. These data suggest that MTMR14 deficiency caused a late-onset inflammation and metabolic dysfunction. Further study demonstrated that this exacerbated metabolic dysfunction and inflammation may be regulated by the phosphoinositide 3 kinase/protein kinase B and extracellular signal-regulated protein kinase signaling pathways. CONCLUSIONS Our current research suggests that MTMR14 deletion induces overweight and adult obesity accompanied by chronic inflammation in an age-dependent manner.

Abstract
OBJECTIVE To associate the nutritional status and the self-perception of nutritional status with the use of licit drugs among adolescents. METHODS Cross-sectional study in which 210 adolescents answered a questionnaire on alcohol and tobacco experimentation and self-perceptions about their nutritional status. The correspondence between the adolescents' perception of their own nutritional status and actual nutritional status was analyzed, as well as associations between nutritional status, self-perception of nutritional status, gender, age, and presence of smokers at home with alcohol and tobacco use. The variables were analyzed separately in a bivariate analysis and, subsequently, a multivariate analysis determined the factors associated with drug use. RESULTS The study included 210 adolescents with a median age of 148 months; 56.6% were females. Of the total sample, 6.6% have tried cigarettes, and 20% have tried alcohol; 32.3% had BMI Z-Score≥1, 12.85% had BMI Z-Score≥2, and 50.7% had a correct perception of his/her weight. After a multivariate analysis, only the self-perception about weight statistically influenced experimentation of tobacco, and patients who identified themselves as having very high weight were more likely to experiment tobacco (odds ratio (OR) 13.57; confidence interval (95% CI) 2.05-89.8; p=0.007); regarding alcohol use, adolescents who identified themselves as having high weight were 2.4 times more likely to experiment with alcohol than adolescents that identified themselves as having normal weight (95% CI 1.08-5.32, p=0.031). CONCLUSIONS Adolescents with self-perception of excess weight may constitute a risk group for alcohol and tobacco use.
