A social media intervention for the families of young Black men with obstructive sleep apnoea.

Objective: To address positive airway pressure (PAP) adherence in adolescents diagnosed with obstructive sleep apnoea (OSA) by pilot testing a novel, online, facilitated, peer-support and health education programme for families. Design Setting and Methods: Families participated in separate Facebook peer-groups (adolescent [n=6] and parent [n=6]) for four weeks, followed by face-to-face interviews. Participants received OSA and PAP educational videos and posts, engaged with questions and polls, and viewed de-identified postings of peer PAP use data. Results: Adolescent participants were young Black males aged 13-17 years (n=6) with obesity (n=5), severe sleep apnoea (100%) and 4-15 months of prior PAP use. Parent participants were mothers (n=4) and fathers (n=2). Four of six young males increased their mean PAP use during the intervention period. Overall, parents were more engaged with the Facebook group page than adolescents, but interviews revealed the online group/peer-support and education provided was highly regarded and appreciated by families. Parents were particularly appreciative of being involved in care and diagnosis in this way. Conclusion: Results of this pilot trial provide important data regarding intervention design, content, and delivery approaches to be considered in the development of future interventions aiming to engage families and improve adolescent PAP adherence.

Perspectives of adolescents with severe obesity on social Media in Preparation for weight-loss surgery: a qualitative study.

BACKGROUND: Currently the most effective treatment for severe obesity in adolescents is weight-loss surgery coupled with lifestyle behavior change. In preparation for weight-loss surgery, adolescents are required to make changes to eating and activity habits (lifestyle changes) to promote long term success. Social media support groups, which are popular among adolescents, have the potential to augment preoperative lifestyle changes. The purpose of this study was to qualitatively assess the perceived role of social media as a support tool for weight-loss, and to identify motivators and constraints to lifestyle changes and social media use in adolescents preparing for weight-loss surgery. METHODS: Thematic analysis of social media comments from 13 (3 male, 10 female) adolescents aged 16 ± 1.3 years with a body mass index (BMI) 45 ± 7.3 kg/m2 enrolled in a weight-management program preparing for bariatric surgery and who participated in a 12-week pilot social media intervention was performed. Participants commented on moderator posts and videos of nutrition, physical activity, and motivation that were shared three to four times per week. Social media comments were coded using NVivo 11.0 to identify recurrent themes and subthemes. RESULTS: 1) Social media provided accountability, emotional support, and shared behavioral strategies. 2) Motivators for lifestyle changes included family support, personal goals, and non-scale victories. 3) Challenges included negative peers, challenges with planning and tracking, and time constraints. CONCLUSION: Adolescents considering bariatric surgery identified social media as a tool for social support and reinforcement of strategies for successful behavior change. Important motivators and challenges to lifestyle changes were identified.

Combined Treatment for Obesity and Depression: A Pilot Study.

OBJECTIVE: Obesity and depression frequently co-occur, and each increases risk for cardiovascular disease (CVD). This study tested whether a combined treatment, targeting obesity and depression simultaneously, would yield greater improvements in weight, mood, and CVD risk factors than treatments that targeted each disease individually. METHODS: Seventy-six participants with obesity and major depression were randomly assigned to (1) behavioral weight control (BWC), (2) cognitive behavioral therapy for depression (CBT-D), or (3) BWC combined with CBT-D. Participants were provided 18 group treatment sessions over 20 weeks. Mood, weight, and CVD risk were assessed at baseline and weeks 8 and 20, with a follow-up visit at week 46. RESULTS: At week 20, participants in combined treatment lost significantly (P < 0.02) more weight (5.2% ± 1.2%) than those assigned to CBT-D (0.8% ± 1.3%) and comparable amounts as those in BWC (3.5% ± 1.3%). Depression scores decreased significantly from baseline levels in each group, with no significant differences between groups. All three groups showed significant improvements in 10-year CVD risk, with no significant differences between groups. Groups did not differ significantly on any of these measures at week 46. CONCLUSIONS: BWC yielded short-term improvements in weight, mood, and CVD risk, comparable to a combined treatment that incorporated CBT-D. Results require replication with a larger sample size.

Assessing the Feasibility of a Social Media to Promote Weight Management Engagement in Adolescents with Severe Obesity: Pilot Study.

BACKGROUND: Severe obesity in adolescents has deleterious physical and psychological complications necessitating frequent multi-disciplinary clinic visits. Greater treatment engagement has been equated with weight-loss. However, traditional medical weight-loss programs for adolescents have high attrition rates. Social media is widely used by adolescents and may enhance medical weight management engagement and success. OBJECTIVE: The first objective was to examine the acceptability and feasibility of using a private social media group as an adjunct to medical weight management in youth ages 14 to 20 years with severe obesity [body mass index (BMI) ≥ 35 kg/m2]. The second objective was to pilot test the use of social media to improve treatment engagement and decrease attrition rates. METHODS: In this single arm, 12 week pre-post study, participants attended individual clinic visits and participated in a moderated private social media group that received nutrition, exercise, and behavior change social media communications or "posts" 3 to 4 times/week. Youth commented and/or liked posts from the moderator and each other. Social media engagement was measured with the number of likes and comments on social media. Clinic attrition was compared, measuring clinic visit attendance 12 weeks prior, during, and after the intervention with mixed linear regression models. Correlations of social media engagement with changes from baseline for BMI, BMI-z score, and psychosocial measures were fit. RESULTS: All 13 enrolled youth completed the study and reported that the group was enjoyable, helpful, reinforced their weight management program, and would recommend using social media to support other youth. The pilot trial was acceptable and feasible. Youth mean weekly engagement (likes + comments) in social media was greater than once a day (8.6 ±3.6). Compared to 12 weeks prior to the intervention, there was no significant decrease in clinic visit attendance at the end of the intervention (M=.231, P=.69) or 12 weeks at the conclusion of the intervention (M=.589, P=.28). Increased social media comments correlated with weight change (r=-.633, P=.04). CONCLUSIONS: This pilot trial demonstrated that the use of social media as an adjunct to medical weight management was feasible and acceptable to adolescents with severe obesity. Based upon these preliminary findings, social media may be an effective way to mitigate attrition from obesity treatment programs, and improve health outcomes in this high-risk population.

A Social Media Peer Group for Mothers To Prevent Obesity from Infancy: The Grow2Gether Randomized Trial.

BACKGROUND: Few studies have addressed obesity prevention among low-income families whose infants are at increased obesity risk. We tested a Facebook peer-group intervention for low-income mothers to foster behaviors promoting healthy infant growth. METHODS: In this randomized controlled trial, 87 pregnant women (Medicaid insured, BMI ≥25 kg/m2) were randomized to the Grow2Gether intervention or text message appointment reminders. Grow2Gether participants joined a private Facebook group of 9-13 women from 2 months before delivery until infant age 9 months. A psychologist facilitated groups featuring a curriculum of weekly videos addressing feeding, sleep, parenting, and maternal well-being. Feasibility was assessed using the frequency and content of participation, and acceptability using surveys. Maternal beliefs and behaviors and infant growth were assessed at birth, 2, 4, 6, and 9 months. Differences in infant growth between study arms were explored. We conducted intention-to-treat analyses using quasi-least-squares regression. RESULTS: Eighty-eight percent (75/85) of intervention participants (42% (36/85) food insecure, 88% (75/85) black) reported the group was helpful. Participants posted 30 times/group/week on average. At 9 months, the intervention group had significant improvement in feeding behaviors (Infant Feeding Style Questionnaire) compared to the control group (p = 0.01, effect size = 0.45). Intervention group mothers were significantly less likely to pressure infants to finish food and, at age 6 months, give cereal in the bottle. Differences were not observed for other outcomes, including maternal feeding beliefs or infant weight-for-length. CONCLUSIONS: A social media peer-group intervention was engaging and significantly impacted certain feeding behaviors in families with infants at high risk of obesity.

A Social Media Peer Group Intervention for Mothers to Prevent Obesity and Promote Healthy Growth from Infancy: Development and Pilot Trial.

BACKGROUND: Evidence increasingly indicates that childhood obesity prevention efforts should begin as early as infancy. However, few interventions meet the needs of families whose infants are at increased obesity risk due to factors including income and maternal body mass index (BMI). Social media peer groups may offer a promising new way to provide these families with the knowledge, strategies, and support they need to adopt obesity prevention behaviors. OBJECTIVE: The aim of this study is to develop and pilot test a Facebook-based peer group intervention for mothers, designed to prevent pediatric obesity and promote health beginning in infancy. METHODS: We conducted in-depth semi-structured interviews with 29 mothers of infants and focus groups with 30 pediatric clinicians, to inform the development of a theory-based intervention. We then conducted a single-group pilot trial with 8 mothers to assess its feasibility and acceptability. All participants were recruited offline at pediatric primary care practices. Participants in the pilot trial joined a private Facebook group, moderated by a psychologist, with a weekly video-based curriculum, and also had the option to meet at a face-to-face event. Within the Facebook group, mothers were encouraged to chat, ask questions, and share photos and videos of themselves and babies practicing healthy behaviors. Consistent with the literature on obesity prevention, the curriculum addressed infant feeding, sleep, activity, and maternal well-being. Feasibility was assessed using the frequency and content of group participation by mothers, and acceptability was measured using online surveys and phone interviews. RESULTS: Based on preferences of mothers interviewed (mean BMI 35 kg/m(2), all Medicaid-insured, mean age 27, all Black), we designed the intervention to include frequent posts with new information, videos showing parents of infants demonstrating healthy behaviors, and an optional face-to-face meeting. We developed a privacy and safety plan that met the needs of participants as well as the requirements of the local institutional review board (IRB), which included use of a "secret" group and frequent screening of participant posts. Clinicians, 97% (29/30) women and 87% (26/30) pediatricians, preferred no direct involvement in the intervention, but were supportive of their patients' participation. In our 8-week, single group pilot trial, all participants (mean BMI 35 kg/m(2), all Medicaid-insured, mean age 28, all Black) viewed every weekly video post, and interacted frequently, with a weekly average of 4.4 posts/comments from each participant. All participant posts were related to parenting topics. Participants initiated conversations about behaviors related to healthy infant growth including solid food introduction, feeding volume, and managing stress. All 8 pilot group participants reported that they found the group helpful and would recommend it to others. CONCLUSIONS: Our methodology was feasible and acceptable to low-income mothers of infants at high risk of obesity, and could be adapted to implement peer groups through social media for underserved populations in varied settings.

Mothers' and Clinicians' Priorities for Obesity Prevention Among Black, High-Risk Infants.

INTRODUCTION: Despite many recommended strategies for obesity prevention during infancy, effectively delivering recommendations to parents in clinical settings is challenging, especially among high-risk populations. This study describes and compares mothers' and clinicians' priorities for obesity prevention during infancy, to facilitate more-effective obesity prevention messaging. METHODS: A discrete choice experiment using maximum difference scaling was administered in 2013 and analyzed in 2013-2014. Twenty-nine low-income, obese mothers of infants and 30 pediatric clinicians from three urban primary care practices rated the relative importance of 16 items relevant to obesity prevention during infancy, in response to this question: Which topic would be most helpful [for new mothers] to learn about to prevent your [their] child from becoming overweight? Response options encompassed the domains of feeding, sleep, parenting (including physical activity and screen time), and maternal self-care. RESULTS: Mothers (all Medicaid-enrolled and black; mean age, 27 years; mean BMI, 35 kg/m(2)) and clinicians (97% female, 87% pediatricians, 13% nurse practitioners) both highly prioritized recognizing infant satiety and hunger cues, and appropriate feeding volume. Mothers rated infant physical activity and maintaining regular routines as 3.5 times more important than clinicians did (p<0.001). Clinicians rated breastfeeding as 3.4 times more important than mothers did (p<0.001). Neither group prioritized learning about screen time or maternal self-care. CONCLUSIONS: Low-income, obese, black mothers of infants highly prioritized learning about many effective obesity prevention strategies, including recognizing hunger and satiety cues, promoting infant activity, and maintaining regular routines. Clinicians may frame preventive guidance to be responsive to these priorities.

Treatment of adolescent obesity comparing self-guided and group lifestyle modification programs: a potential model for primary care.

Lifestyle modification programs (LMP) for weight loss in adolescents with obesity are effective but not available. Primary care may be a setting for reaching more adolescents. Two models of LMP for use in primary care were examined. Adolescents and caregivers enrolled in a 1-year randomized trial comparing Group LMP with Self-Guided LMP. All participants (N = 169) received the same treatment recommendations and met with a health coach six times in clinic. Group LMP participants had an additional 17 group sessions; those in Self-Guided LMP followed the remainder of the program at home with parental support. The primary outcome was percentage change in initial body mass index. The mean (SE) 1.31% (0.95%) reduction in Group LMP did not differ significantly from the 1.17% (0.99%) decrease in the Self-Guided LMP (p = 0.92). Both treatments were significantly effective in reducing body mass index. Given its brevity, the Self-Guided LMP offers an innovative approach for primary care.

The association between weight loss in caregivers and adolescents in a treatment trial of adolescents with obesity.

OBJECTIVE: The relationship between weight change in caregivers and their adolescents was evaluated following a randomized trial of lifestyle modification for adolescents, which included either a conventional diet or meal replacements. METHODS: Adolescents (N = 113) had an M ± SD age of 15.0 ± 1.3 years (62% African American; 26% Caucasian, 12% other; 81% female) and body mass index of 37.1 ± 5.1 kg/m(2). RESULTS: Mixed effects models yielded a significant association between percentage change in body mass index of caregivers and adolescents from baseline to months 4 and 12 (p = .01). When caregivers lost above the median (-1.67%) at month 4, their adolescents achieved a significantly greater loss at month 12 (-9.1 ± 1.3%) compared with adolescents whose caregivers lost less than the median (-4.3 ± 1.3%) (p = .003). CONCLUSION: Engaging caregivers in their own weight loss efforts during adolescent weight loss treatment may improve adolescent weight loss.

Threshold for improvement in insulin sensitivity with adolescent weight loss.

OBJECTIVES: To assess the association of weight loss and insulin sensitivity, glucose tolerance, and metabolic syndrome (MS) in obese adolescents following weight loss treatment, and to determine the threshold amount of weight loss required to observe improvements in these measures. STUDY DESIGN: A randomized, controlled behavioral weight loss trial was conducted with 113 obese adolescents. Changes in fasting insulin, homeostasis model assessment of insulin resistance, whole body insulin sensitivity index (WBISI), body mass index (BMI), and MS criteria were assessed at baseline and at month 4. RESULTS: There was significant improvement in all measures of insulin sensitivity at month 4. Mean fasting insulin dropped from 22.3 to 16.6 µU/mL (P < .0001). Homeostasis model assessment of insulin resistance decreased significantly from 4.9 to 3.7 (P = .001) and WBISI increased significantly from 2.87 to 3.98 (P < .0001). An 8% reduction in BMI led to a significant improvement in WBISI (P = .03) and was the optimal threshold. Fewer individuals met criteria for MS after weight loss (P = .0038), although there were no significant changes in the individual features of the syndrome. CONCLUSIONS: In this trial, weight loss at month 4 was associated with improved insulin sensitivity in obese adolescents. An approximate decrease in BMI of 8% was the threshold level at which insulin sensitivity improved. As more weight loss programs are designed for obese adolescents, it will be important to have reasonable weight loss goals that will yield improvements in metabolic and cardiovascular disease risk factors.

Caregiver concern in adolescents with persistent obesity: the importance of quality of life assessment.

OBJECTIVE: To examine female caregiver and adolescent dyad characteristics that predict the female caregiver's concern about their adolescent's weight and the degree to which caregiver concern predicts desire for physician intervention. METHOD: Fifty-three caregivers of adolescents with persistent obesity were asked to report on their adolescent's quality of life (QOL), weight status, concern about their adolescent's weight, and desire for physician intervention. RESULTS: Results indicated that only caregiver-reported QOL was a meaningful predictor of caregiver concern for African-American adolescents with persistent obesity accounting for 51% of the variance and that caregiver concern predicted desire for physician intervention accounting for 46% of the variance. CONCLUSION: Based on these findings, it is recommended that practitioners assess caregiver perception of obesity-specific QOL in their adolescent patients with persistent obesity, particularly those who are African-American.

Weight reduction in obese adolescents with and without binge eating.

Little is known about binge eating (BE) in adolescents. The primary aim of the present study was to examine the relationship between BE and weight loss in adolescents (BMI ≥95th percentile) enrolled in a randomized controlled trial of behavioral and pharmacologic treatment of obesity. Participants were 82 treatment-seeking adolescents (BMI = 37.9 ± 3.8 kg/m(2); age = 14.1 ± 1.2 years; 67% females; 42% African American, 55% white). Participants completed the Children's Depression Inventory (CDI), the Piers Harris Self-Esteem Questionnaire, and the Eating Inventory (including cognitive restraint, disinhibition, and hunger scales). BE was assessed by a questionnaire and a confirmatory interview. At baseline, 24% of participants met criteria for BE (N = 13 met full BE disorder (BED) criteria; N = 7 met subthreshold BE). There were no significant differences in percentage reduction in initial BMI between participants with or without BE at month 6 (-7.0 ± 1.6 vs. -6.9 ± 0.9%) or month 12 (-8.8 ± 2.4 vs. -8.3 ± 1.3%) (omnibus main effect BE P = 0.89, interaction BE × time P = 0.84, interaction BE × drug P = 0.61). The rate of BE declined significantly over time from 24% (n = 20) at baseline to 8% (n = 6) at month 6 and 3% (n = 2) at month 12 (P = 0.003). There were significant decreases in hunger and disinhibition as well as an increase in cognitive restraint over time (all P ≤ 0.0001). Findings suggest a combination of behavioral and pharmacologic therapy may produce both weight loss and improvement in BE.

Racial differences in obese youth's perception of health care and weight loss.

Within the United States, minority youth are at greater risk of becoming overweight/obese and are less likely to receive preventive health care. The authors examined several domains of preventive health care perceptions among persistently overweight/obese white and black adolescents. A total of 55 youth (29 white, 26 black) who had previously sought weight management treatment participated in a follow-up study 4 years later (M (years) = 4.2 ± 0.8). All participants remained overweight (5% at the 85th- 94th BMI percentiles) or obese (95% ≥ 95th BMI percentile), with no significant difference in weight by race. Relative to whites, blacks perceived greater physician concern about and counseling regarding weight (P (concern) < .01; P (counsel) < .01), eating habits(P (concern) < .001; P (counsel) < .01), and physical activity (P (concern) < .001; P (counsel) < .05). Although whites reported knowing more weight-related comorbidities than blacks, there were no group differences in number of weight loss methods attempted (M (methods) = 7.5 ± 2.7). Overall, there were no group differences in perceptions of risk. Physicians may be appropriately focusing efforts on educating black youth, but knowledge and behavior gaps persist.

Meal replacements in the treatment of adolescent obesity: a randomized controlled trial.

Use of meal replacements (MRs) in lifestyle modification programs (LMPs) for obese adults significantly increases weight loss, compared with prescription of an isocaloric conventional diet (CD). This 12-month randomized trial examined 113 obese adolescents (mean ± s.d. age of 15.0 ± 1.3 years and BMI of 37.1 ± 5.1 kg/m2) who were assigned to a LMP, combined with meal plans of 1300-1500 kcal/day of CD (self-selected foods) or MR (three SlimFast shakes, one prepackaged meal, five vegetable/fruit servings). After month 4 (phase 1), participants originally treated with MR were unmasked to their phase 2 (months 5-12) random assignment: continued use of MR (i.e., MR+MR) or transitioned to CD (i.e., MR+CD). Participants initially treated with CD in phase 1, continued with CD (i.e., CD). All three groups were treated for an additional 8 months (phase 2). Regression models were used to evaluate percentage change in BMI from baseline to month 4 (phase 1), months 5-12 (phase 2), and baseline to month 12. At month 4, participants assigned to MR (N = 65) achieved a mean (±s.e.) 6.3 ± 0.6% reduction in BMI, compared to a significantly (P = 0.01) smaller 3.8 ± 0.8% for CD participants (N = 37). In phase 2, BMI increased significantly (P < 0.001) in all three conditions, resulting in no significant (P = 0.39) differences between groups in percentage change in BMI at month 12. Across groups, mean reduction in BMI from baseline to month 12 was 3.4 ± 0.7% (P < 0.01). Use of MR significantly improved short-term weight loss, compared with CD, but its continued use did not improve maintenance of lost weight.

Maintenance of weight loss in adolescents: current status and future directions.

There is a dearth of research on the long-term efficacy and safety of treatments for adolescent obesity. This narrative review examined several approaches to treatment, focusing on long-term effectiveness data in adolescents, as well as relevant findings from studies of adults. The available research suggests that lifestyle modification has promise in obese adolescents, although it is not clear that any particular dietary or physical activity approach is more effective than another. Meal replacements are quite effective in adults and deserve further research in adolescents. Extending the length of treatment to teach weight loss maintenance skills is likely to improve long-term outcomes in adolescents, and delivering treatment via the Internet or telephone is a novel way of doing so. Treatment that combines lifestyle modification with the medication orlistat generally appears to be safe but only marginally superior to lifestyle modification alone. More research is needed on the management of adolescent obesity, which has been overlooked when compared with research on the treatment of obesity in children and adults.
