Insights

Remote delivery of the JOIN for ME program improved child weight status in low-income families. Attendance and food security were linked to better outcomes in this intensive health behavior and lifestyle treatment study.

Area of Science:

  • Public Health
  • Pediatric Obesity
  • Health Behavior Interventions

Background:

  • Childhood obesity interventions aim to disseminate evidence-based treatments to low-income communities.
  • The CDC Childhood Obesity Research Demonstration (CORD) 3.0 projects focused on adapting and testing intensive health behavior and lifestyle treatments (IHBLTs).
  • RI CORD 3.0 specifically adapted and evaluated the remote implementation of the JOIN for ME IHBLT.

Purpose of the Study:

  • To adapt and test the effectiveness of the JOIN for ME IHBLT for remote implementation.
  • To assess the context for remote delivery of the intervention to families from low-income communities.
  • To evaluate changes in child and caregiver weight status, nutrition, physical activity, and quality of life.

Main Methods:

  • Recruited 111 children (aged 6-12 years, BMI >85th percentile) and their caregivers from a federally qualified health center or community setting.
  • Participants were randomized to an immediate or 4-month delayed treatment condition for the 10-month remotely delivered intervention.
  • Assessed weight status, Family Nutrition and Physical Activity (FNPA), quality of life, program acceptability, and intervention fidelity.

Main Results:

  • The active treatment group showed significant improvements in FNPA compared to the delayed group at 4 months.
  • No significant differences in child or caregiver weight status were observed between groups at 4 months.
  • At 10 months, children showed modest decreases in median BMI (2.90%), BMI-for-age percentiles (3.89%), and zBMI units (0.16).
  • Higher session attendance and baseline food security were associated with greater weight status changes.

Conclusions:

  • The adapted JOIN for ME program was successfully implemented remotely.
  • The intervention demonstrated significant, modest improvements in child weight status.
  • Findings support the feasibility and effectiveness of remote IHBLTs for childhood obesity in underserved populations.

Community Based Intervention01:30

Community Based Intervention

Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.

Test for Homogeneity01:23

Test for Homogeneity

The goodness–of–fit test can be used to decide whether a population fits a given distribution, but it will not suffice to decide whether two populations follow the same unknown distribution. A different test, called the test for homogeneity, can be used to conclude whether two populations have the same distribution. To calculate the test statistic for a test for homogeneity, follow the same procedure as with the test of independence. The hypotheses for the test for homogeneity can...

Longitudinal Research02:20

Longitudinal Research

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Pulse Assessment Sites01:11

Pulse Assessment Sites

Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...

Testing Water Quality01:14

Testing Water Quality

When the quality of water for concrete preparation is uncertain, its impact on the setting time of cement and compressive strength of mortar is assessed by comparison with de-ionized or distilled water benchmarks. American Society for Testing and Materials (ASTM) C1602 requires the setting times to be within 90 minutes of the control, British Standard (BS) 3146:1980 allows a 30-minute variance in the initial setting, while British Standards European Norm (BS EN) 1008 specifies initial setting...

Quality Assurance01:19

Quality Assurance

Quality assurance is the overarching term used to describe the activities employed to ensure the proper performance of a system. These activities can be classified into three categories: quality control, quality assessment, and internal corrective measures. Typically, these activities work cyclically: quality control is performed before and during the analysis, while quality assessment occurs during and after the investigation. Internal corrective measures are implemented based on the findings...
