Getting to More Effective Weight Management in Antipsychotic-Treated Youth: A Survey of Barriers and Preferences

Understanding the Perspective of Youths on Undergoing Metabolic Monitoring While on Second-Generation Antipsychotics: Challenges, Insight, and Implications

Introduction: Prescription of second-generation antipsychotics (SGAs) in youths is rapidly increasing globally, despite the potential for significant adverse effects and long-term health consequences. A known adverse reaction resulting from SGAs is metabolic syndrome (MS). Youths exposed to antipsychotics are at higher risk than adults for adverse drug reactions, including adverse events such as MS (with weight gain as the most significant adverse outcome) and other long-term endocrinological abnormalities. This study aimed to explore the experiences of young patients on factors impacting barriers to metabolic monitoring of SGAs and the strategies to address those barriers thereby providing further guidance on policy and service delivery. Methods: Semi-structured interviews were conducted with patients (youths who were prescribed SGAs) who attended Child and Youth Mental Health Services. The interviews focused on barriers to monitoring and strategies to enhance rates of monitoring that could be customized across study sites. Results: Young patients revealed that none of them had any concerns or objections to receiving anthropometric metabolic measurements. However, they seemed concerned to undergo blood tests as part of the metabolic monitoring process. Specifically, youths cited their fear of the needles as barrier to undergo the required blood tests. Youths have also reported that their dislike to healthy foods and exercise being the most common challenge they face while trying to engage in a healthy lifestyle to manage the SGAs resulted weight gain. Conclusion: Prescribers are recommended to actively engage young patients about the expected SGAs-induced adverse effects, the importance of conducting metabolic monitoring, and how to prevent and minimize the expected adverse effects from the start of initiating SGAs. This could be a vital step toward a successful treatment as the insight of youths into the details of the chosen treatment can play a significant role into treatment adherence and recovery.

Use of an Interactive Obesity Treatment Approach in Individuals With Severe Mental Illness: Feasibility, Acceptability, and Proposed Engagement Criteria

BACKGROUND

Digital and mobile health interventions are increasingly being used to support healthy lifestyle change, including in certain high-risk populations such as those with severe mental illnesses (SMIs). Life expectancy in this population lags 15 years behind counterparts in the general population, primarily due to obesity-related health conditions.

OBJECTIVE

We tested the feasibility and usability of a 12-week interactive obesity treatment approach (iOTA) to adults with chronic SMIs (depression, bipolar disorder and schizophrenia spectrum disorder) receiving treatment in community settings. The iOTA incorporates short message service (SMS) text messages to supplement monthly in-person health coaching.

METHODS

Factors hypothesized to be associated with weight change were illness severity and treatment engagement. Severe psychiatric symptoms were defined as baseline Clinical Global Impression severity score of >5. Criterion engagement was defined as a text messaging response rate >80% during the first 4 weeks of treatment. Disordered eating, assessed with the Loss of Control Over Eating Scores, was also evaluated. Participants provided qualitative data, further informing assessment of intervention feasibility, usability, and acceptability.

RESULTS

A total of 26 participants were enrolled. The mean age was 48.5 (SD 15.67) years; 40% (10/26) were Black and 60% (15/26) female. Participants with lower symptom severity and adequate engagement demonstrated significantly decreased weight (F1,16=22.54, P<.001). Conversely, high symptom severity and lower text message response rates were associated with trend-level increases in weight (F1,7=4.33, P=.08). Loss-of-control eating was not observed to impact treatment outcome. Participants voiced preference for combination of live health coaching and text messaging, expressing desire for personalized message content.

CONCLUSIONS

These results demonstrate the feasibility of delivering an adapted iOTA to SMI patients receiving care in community settings and suggest testable criteria for defining sufficient treatment engagement and psychiatric symptom severity, two factors known to impact weight loss outcomes. These important findings suggest specific adaptations may be needed for optimal treatment outcomes in individuals with SMI.

Using Innovation-Corps (I-Corps™) Methods to Adapt a Mobile Health (mHealth) Obesity Treatment for Community Mental Health Settings

Background

We employed Innovation Corps (I-Corps™) methods to adaptation of a mobile health (mHealth) short-message-system (SMS) -based interactive obesity treatment approach (iOTA) for adults with severe mentall illness receiving care in community settings.

Methods

We hypothesized "jobs to be done" in three broad stakeholder groups: "decision makers" (DM = state and community clinic administrators), "clinician consumers" (CC = case managers, peer supports, nurses, prescribers) and "service consumers" (SC = patients, peers and family members). Semistructured interviews (N = 29) were recorded and transcribed ver batim and coded based on pragmatic-variant grounded theory methods.

Results

Four themes emerged across groups: education, inertia, resources and ownership. Sub-themes in education and ownership differed between DM and CC groups on implementation ownership, intersecting with professional development, suggesting the importance of training and supervision in scalability. Sub-themes in resources and intertia differed between CC and SC groups, suggesting illness severity and access to healthy food as major barriers to engagement, whereas the SC group identified the need for enhanced emotional support, in addition to pragmatic skills like menu planning and cooking, to promote health behavior change. Although SMS was percieved as a viable education and support tool, CC and DM groups had limited familiarity with use in clinical care delivery.

Conclusions

Based on customer discovery, the characteristics of a minimum viable iOTA for implementation, scalability and sustainability include population- and context-specific adaptations to treatment content, interventionist training and delivery mechanism. Successful implementation of an SMS-based intervention will likely require micro-adaptations to fit specific clinical settings.

In search of measures to improve the detection of increased cardiometabolic risk in children using second-generation antipsychotic medications

PURPOSE

Second-generation antipsychotic medications (SGAs) are widely used in child psychiatry. SGA-induced metabolic disturbances are common in children, but monitoring practices need systematisation. The study's aims were to test an SGA-monitoring protocol, examine the distributions of metabolic measurements compared to reference values in child psychiatry patients, and determine whether using a homeostasis model for the assessment of insulin resistance (HOMA-IR) and triglyceride/high-density lipoprotein (TG/HDL) ratio could improve the detection of increased cardiometabolic risk.

MATERIALS AND METHODS

A systematic monitoring protocol was implemented. Weight and height, blood pressure, fasting glucose, insulin, HDL, and TG were measured at baseline and four times during follow-up. HOMA-IR, TG/HDL ratio and zBMI were calculated. Age-, gender- and BMI-specific percentile curves for HOMA-IR were used to define elevated cardiometabolic risk.

RESULTS

The study patients (n = 55, mean age 9.9 years) were followed for a median of 9 months. A disadvantageous, statistically significant shift, often appearing within the reference range, was seen in zBMI, TG, HDL, glucose, insulin, HOMA-IR, and TG/HDL ratio. The increase in HOMA-IR appeared earlier than individual laboratory values and was more evident than the TG/HDL ratio increase. An HOMA-IR cut point of 1.98 resulted in a sensitivity and specificity of 83%. Compared to a previous study performed in the same location, the monitoring rates of metabolic parameters improved.

CONCLUSION

The monitoring protocol implementation improved the monitoring of metabolic parameters in child psychiatric patients using SGAs. Using HOMA-IR as part of systematic SGA monitoring could help detect metabolic adverse effects.

Barriers and facilitators to physical education, sport, and physical activity program participation among children and adolescents with psychiatric disorders: a systematic review

Children and adolescents with heterogeneous psychiatric disorders, of whom over 50% have a second psychiatric comorbidity, have low rates of physical activity and experience unique challenges to engaging in community-based exercise programming, school-based physical education programming, and targeted physical activity interventions. This contributes to elevated rates of gross and fine motor delays, lower mood and self-regulation, and increased risk of chronic diseases such as obesity and type 2 diabetes. Perform a systematic scoping review of the literature to assess known barriers to and facilitators of engaging in physical activity programming among children and adolescents with heterogeneous and/or comorbid psychiatric disorders, in order to improve engagement among this population in real world intervention settings. Systematic Boolean diagnostic and physical activity search terms were entered into PubMed, MEDLINE, PsycINFO and Web of Science for English-language studies published between 2005 and 2020, examining barriers and facilitators for common psychiatric diagnoses and general psychiatric population's engagement in physical activity, physical education, sports, or exercise interventions. Two reviewers independently reviewed titles, abstracts and full articles to determine inclusion. A total of 5,198 articles were returned; 39 relating to children and adolescents were qualified for full-text review. After review, 24 studies were included addressing barriers and facilitators across multiple diagnoses; 7 studies were quantitative, 10 were qualitative, and 7 were mixed methods. Major barriers included low motivation, low self-efficacy, depleted parental reserve capacity, social isolation, lack of staff training, and safety concerns. Major facilitators included peer support/engagement, exergames, supportive parental behaviors, and inclusive/adaptive programming. Numerous barriers and facilitators to physical activity have been identified which should inform community, school, clinical, and research intervention program design. Further research is needed to develop effective strategies that address the challenges to inclusion that children and adolescents with heterogeneous and/or comorbid psychiatric disorders face.

Dietary Consumption Among Youth with Antipsychotic-Induced Weight Gain and Changes Following Healthy Lifestyle Education

Background: Youth treated with antipsychotic medications are high risk for weight gain, increased lipids/glucose, and development of metabolic syndrome. Little is known about the dietary intake/nutritional adequacy in this vulnerable population, and effect on weight gain. This secondary data analysis describes the baseline intake and changes in diet after receiving healthy lifestyle education/counseling over 6 months, in a sample of youth with antipsychotic-induced weight gain. Methods: The U.S. Department of Agriculture (USDA) Automated Multiple-Pass Method 24-hour dietary recall was administered to 117 youth at baseline, 3 months, and 6 months. Parent/child received personalized healthy lifestyle education sessions over 6 months. Baseline intake was compared with the USDA Recommended Daily Allowance using independent samples t-tests. Individual dietary covariates were examined for change over 6 months using longitudinal linear mixed modeling. Influence of each on body mass index (BMI) z-score change was tested in a pooled group analysis and then compared by treatment group. Results: Pooled analysis revealed baseline consumption high in carbohydrates, fat, protein, sugar, and refined grains, while low in fruit/vegetables, whole grains, fiber, and water. Change over 6 months demonstrated a statistically significant decrease in daily calories (p = 0.002), carbohydrates (p = 0.003), fat (p = 0.012), protein (p = 0.025), sugar (p = 0.008), refined grains (p = 0.008), total dairy (p = 0.049), and cheese (p = 0.027). Small increases in fruits/vegetables were not statistically significant, although the Healthy Eating Index subscores for total vegetables (p = 0.013) and dark green/orange vegetables (p = 0.034) were. No dietary covariates were predictors of change in BMI z-score. Nondietary predictors were parent weight/BMI and treatment group, with the metformin and switch groups experiencing significant decreases in BMI z-score. Conclusions: Further pediatric studies are necessary to assess the effects of antipsychotic medications on dietary intake, and test efficacy of healthy lifestyle interventions on change in nutrition. The relationship of nutrition to cardiometabolic health in this population must be further investigated. Clinical Trial Registration number: NCT02877823.

A Smartphone-Based Technique to Detect Dynamic User Preferences for Tailoring Behavioral Interventions: Observational Utility Study of Ecological Daily Needs Assessment

BACKGROUND

Mobile health apps are promising vehicles for delivering scalable health behavior change interventions to populations that are otherwise difficult to reach and engage, such as young adults with psychiatric conditions. To improve uptake and sustain consumer engagement, mobile health interventions need to be responsive to individuals' needs and preferences, which may change over time. We previously created an ecological daily needs assessment to capture microprocesses influencing user needs and preferences for mobile health treatment adaptation.

OBJECTIVE

The objective of our study was to test the utility of a needs assessment anchored within a mobile app to capture individualized, contextually relevant user needs and preferences within the framework of a weight management mobile health app.

METHODS

Participants with an iOS device could download the study app via the study website or links from social media. In this fully remote study, we screened, obtained informed consent from, and enrolled participants through the mobile app. The mobile health framework included daily health goal setting and self-monitoring, with up to 6 daily prompts to determine in-the-moment needs and preferences for mobile health-assisted health behavior change.

RESULTS

A total of 24 participants downloaded the app and provided e-consent (22 female; 2 male), with 23 participants responding to at least one prompt over 2 weeks. The mean length of engagement was 5.6 (SD 4.7) days, with a mean of 2.8 (1.1) responses per day. We observed individually dynamic needs and preferences, illustrating daily variability within and between individuals. Qualitative feedback indicated preferences for self-adapting features, simplified self-monitoring, and the ability to personalize app-generated message timing and content.

CONCLUSIONS

The technique provided an individually dynamic and contextually relevant alternative and complement to traditional needs assessment for assessing individually dynamic user needs and preferences during treatment development or adaptation. The results of this utility study suggest the importance of personalization and learning algorithms for sustaining app engagement in young adults with psychiatric conditions. Further study in broader user populations is needed.

Adiposity, Hepatic Triglyceride, and Carotid Intima Media Thickness During Behavioral Weight Loss Treatment in Antipsychotic-Treated Youth: A Randomized Pilot Study

Objectives: The purpose of this pilot study was to evaluate changes in adiposity, carotid intima media thickness (CIMT), and hepatic fat content measured via magnetic resonance imaging-estimated hepatic proton density fat fraction (PDFF) in antipsychotic (AP)-treated youth versus nonpsychiatric (NP) participants during participation in a 16-week behavioral weight loss (BWL) intervention. Subjects/Methods: Overweight/obese AP-treated youth (n = 26) were randomized 2:1 to weekly treatment versus recommended care (RC) over 16 weeks. NP controls (n = 21) were assigned to weekly treatment. Dual-energy X-ray absorptiometry (DEXA)-measured adiposity, CIMT, and PDFF were measured at baseline and 16 weeks. Analyses assessed group differences in the effect of BWL on adiposity, CIMT, and PDFF. Results: BWL was well tolerated in both AP-treated and NP groups. DEXA-measured fat decreased significantly in the NP group (F[1,16] = 11.81, p = 0.003), with modest improvements in adiposity and hepatic fat in the AP-treated group, while an increase in adiposity was observed in the RC group. Significant differences in endpoint DEXA total fat (F[2,34] = 4.81, p = 0.01) and PDFF (F[2,30] = 3.60, p = 0.04) occurred across treatment groups, explained by larger improvements in NP versus RC youth in DEXA total fat (p = 0.03) and PDFF (p = 0.04). Conclusions: Intensive, family-based BWL treatment can improve whole-body adiposity and liver fat in obese youth, with decreases or attenuation of additional fat gain observed in AP-treated youth.

Community Mental Health Providers' Beliefs About Addressing Weight Loss Among Youth Clients with Serious Emotional Disturbance and Overweight/Obesity: An Elicitation Study

Youth with Serious Emotional Disturbance (SED) have high rates of overweight/obesity. Factors influencing mental health provider intentions to deliver weight-related advice are unclear. This study used qualitative methodology and Theory of Planned Behavior (TPB) constructs to examine these factors. Community mental health providers serving youth with SED were recruited via convenience sampling and an online provider list. Participants completed an open-ended TPB-based questionnaire online. Content analysis identified thematic beliefs. Twenty-one providers completed the questionnaire. Providers identified behavioral beliefs (e.g., client defensiveness), normative beliefs (e.g., medical professionals), and control beliefs (e.g., limited resources) that impact decisions to provide weight-related advice. Knowledge of factors that may influence providers' delivery of weight-related advice may lead to more effective healthy lifestyle programming for youth with SED.
