An explanation for the accuracy of sensor-based measures of energy intake: Amount of food consumed matters more than dietary composition.

Understanding and intervening on eating behavior often necessitates measurement of energy intake (EI); however, commonly utilized and widely accepted methods vary in accuracy and place significant burden on users (e.g., food diaries), or are costly to implement (e.g., doubly labeled water). Thus, researchers have sought to leverage inexpensive and low-burden technologies such as wearable sensors for EI estimation. Paradoxically, one such methodology that estimates EI via smartwatch-based bite counting has demonstrated high accuracy in laboratory and free-living studies, despite only measuring the amount, not the composition, of food consumed. This secondary analysis sought to further explore this phenomenon by evaluating the degree to which EI can be explained by a sensor-based estimate of the amount consumed versus the energy density (ED) of the food consumed. Data were collected from 82 adults in free-living conditions (51.2% female, 31.7% racial and/or ethnic minority; Mage = 33.5, SD = 14.7) who wore a bite counter device on their wrist and used smartphone app to implement the Remote Food Photography Method (RFPM) to assess EI and ED for two weeks. Bite-based estimates of EI were generated via a previously validated algorithm. At a per-meal level, linear mixed effect models indicated that bite-based EI estimates accounted for 23.4% of the variance in RFPM-measured EI, while ED and presence of a beverage accounted for only 0.2% and 0.1% of the variance, respectively. For full days of intake, bite-based EI estimates and ED accounted for 41.5% and 0.2% of the variance, respectively. These results help to explain the viability of sensor-based EI estimation even in the absence of information about dietary composition.

Juntos hacemos la diferencia [together we make the difference]: A network analysis of Latinx caregivers' use of youth support services.

Latinx families face unique barriers to accessing traditional youth mental health services and may instead rely on a wide range of supports to meet youth emotional or behavioral concerns. Previous studies have typically focused on patterns of utilization for discrete services, classified by setting, specialization, or level of care (e.g., specialty outpatient, inpatient, informal supports), yet little is known about how youth support services might be accessed in tandem. This analysis used data from the Pathways to Latinx Mental Health study - a national sample of Latinx caregivers (N = 598) from across the United States collected at the start of the coronavirus pandemic (i.e., May-June 2020) - to describe the broad network of available supports that are used by Latinx caregivers. Using exploratory network analysis, we found that the use of youth psychological counseling, telepsychology, and online support groups was highly influential on support service utilization in the broader network. Specifically, Latinx caregivers who used one or more of these services for their child were more likely to report utilizing other related sources of support. We also identified five support clusters within the larger network that were interconnected through specific sources of support (i.e., outpatient counseling, crisis, religious, informal, and non-specialty). Findings offer a foundational look at the complex system of youth supports available to Latinx caregivers, highlighting areas for future study, opportunities to advance the implementation of evidence-based interventions, and channels through which to disseminate information about available services.

Ecological momentary assessment of changes in eating behaviors, appetite, and other aspects of eating regulation in Roux-en-Y gastric bypass and sleeve gastrectomy patients.

Bariatric surgery can have profound impacts on eating behaviors and experiences, yet most prior research studying these changes has relied on retrospective self-report measures with limited precision and susceptibility to bias. This study used smartphone-based ecological momentary assessment (EMA) to evaluate the trajectory of change in eating behaviors, appetite, and other aspects of eating regulation in 71 Roux-en-Y gastric bypass and sleeve gastrectomy patients assessed preoperatively and at 3, 6, and 12-months postoperative. For some outcomes, results showed a consistent and similar pattern for SG and RYGB where consumption of sweet and high-fat foods and hunger, desire to eat, ability to eat right now, and satisfaction with amount eaten all improved from pre-to 6-months post-surgery with some degree of deterioration at 12-months post-surgery. By contrast, other variables, largely related to hedonic hunger and craving and desire for specific foods, showed less consistent patterns that differed by surgery type. While the findings suggest an overall pattern of improvement in eating patterns following bariatric surgery, they also highlight how a return to preoperative habits may begin as early as 6 months after surgery. Additional research is needed to understand mechanisms that promote changes in eating behavior after surgery, and how best to intervene to preserve beneficial effects.

The Effectiveness of School-Based Mental Health Services for Elementary-Aged Children: A Meta-Analysis.

OBJECTIVE: Given problems and disparities in the use of community-based mental health services for youth, school personnel have assumed frontline mental health service roles. To date, most research on school-based services has evaluated analog educational contexts with services implemented by highly trained study staff, and little is known about the effectiveness of school-based mental health services when implemented by school professionals. METHOD: Random-effects meta-analytic procedures were used to synthesize effects of school-based mental health services for elementary school-age children delivered by school personnel and potential moderators of treatment response. Forty-three controlled trials evaluating 49,941 elementary school-age children met the selection criteria (mean grade 2.86, 60.3% boys). RESULTS: Overall, school-based services demonstrated a small-to-medium effect (Hedges g = 0.39) in decreasing mental health problems, with the largest effects found for targeted intervention (Hedges g = 0.76), followed by selective prevention (Hedges g = 0.67), compared with universal prevention (Hedges g = 0.29). Mental health services integrated into students' academic instruction (Hedges g = 0.59), those targeting externalizing problems (Hedges g = 0.50), those incorporating contingency management (Hedges g = 0.57), and those implemented multiple times per week (Hedges g = 0.50) showed particularly strong effects. CONCLUSION: Considering serious barriers precluding youth from accessing necessary mental health care, the present meta-analysis suggests child psychiatrists and other mental health professionals are wise to recognize the important role that school personnel, who are naturally in children's lives, can play in decreasing child mental health problems.
