Comparative Effectiveness of Clinical-Community Childhood Obesity Interventions

Abstract

Novel approaches to care delivery that leverage clinical and community resources could improve body mass index (BMI) and family-centered outcomes.OBJECTIVE To examine the extent to which 2 clinical-community interventions improved child BMI z score and health-related quality of life, as well as parental resource empowerment in the Connect for Health Trial. DESIGN, SETTING, AND PARTICIPANTSThis 2-arm, blinded, randomized clinical trial was conducted from June 2014 through March 2016, with measures at baseline and 1 year after randomization. This intent-to-treat analysis included 721 children ages 2 to 12 years with BMI in the 85th or greater percentile from 6 primary care practices in Massachusetts.INTERVENTIONS Children were randomized to 1 of 2 arms: (1) enhanced primary care (eg, flagging of children with BMI Ն 85th percentile, clinical decision support tools for pediatric weight management, parent educational materials, a Neighborhood Resource Guide, and monthly text messages) or (2) enhanced primary care plus contextually tailored, individual health coaching (twice-weekly text messages and telephone or video contacts every other month) to support behavior change and linkage of families to neighborhood resources. MAIN OUTCOMES AND MEASURESOne-year changes in age-and sex-specific BMI z score, child health-related quality of life measured by the Pediatric Quality of Life 4.0, and parental resource empowerment. RESULTS At1year,weobtainedBMIzscoresfrom664children(92%)andfamily-centeredoutcomes from 657 parents (91%). The baseline mean (SD) age was 8.0 (3.0) years; 35% were white (n = 252), 33.3% were black (n = 240), 21.8% were Hispanic (n = 157), and 9.9% were of another race/ethnicity (n = 71). In the enhanced primary care group, adjusted mean (SD) BMI z score was 1.91 (0.56) at baselineand1.85(0.58)at1year,animprovementof−0.06BMIzscoreunits(95%CI,−0.10to−0.02) from baseline to 1 year. In the enhanced primary care plus coaching group, the adjusted mean (SD) BMI z score was 1.87 (0.56) at baseline and 1.79 (0.58) at 1 year, an improvement of −0.09 BMI z score units (95% CI, −0.13 to −0.05). However, there was no significant difference between the 2 intervention arms (difference, −0.02; 95% CI, −0.08 to 0.03; P = .39). Both intervention arms led to improved parental resource empowerment: 0.29 units (95% CI, 0.22 to 0.35) higher in the enhanced primary care group and 0.22 units (95% CI, 0.15 to 0.28) higher in the enhanced primary care plus coaching group. Parents in the enhanced primary care plus coaching group, but not in the enhanced care alone group, reported improvements in their child's health-related quality of life (1.53 units; 95% CI, 0.51 to 2.56). However, there were no significant differences between the intervention arms in either parental resource empowerment (0.07 units; 95% CI, −0.02 to 0.16) or child health-related quality of life (0.89 units; 95% CI, −0.56 to 2.33).

Racial Disparities in Obesity Treatment

“…Recent research trials have attempted to augment standard lifestyle and behavioral treatment programs to cater to diverse populations by adding contextually specific treatment, which includes individual health coaching and the linking of families to neighborhood/community resources. However, so far, these programs have failed to show statistically significant differences from normal behavioral therapy and lifestyle interventions [62]. This result seems to remain true for racial/ethnic minorities.…”

Capacity‐oriented approaches to developing childhood obesity interventions: a systematic review

“…The positive deviance‐based interventions showed no difference from their comparison in adiposity outcomes . As the comparison groups also received an intervention of similar intensity in both studies, it is difficult to ascertain these interventions’ true efficacy.…”

“…There were two studies with published results using positive deviance to inform their intervention (Foster 2016 and Taveras 2017 ). Both studies were randomized clinical trials (RCTs) with two arms, although Taveras et al .…”

Zooming Toward a Telehealth Solution for Vulnerable Children with Obesity During Coronavirus Disease 2019

“…Some evidence supports the use of telehealth or mobile health interventions as an adjunct to pediatric weight management as feasible and cost-effective, 8,9 but little data exists on the efficacy or effectiveness of exclusive telehealth for pediatric weight management. In the time of COVID-19 closures and physical distancing, telehealth has become a necessary default.…”

“…Phone visits provide limited reimbursement and there is no reimbursement for texting interventions, despite evidence of their effectiveness as adjuncts. 9 5. Effectiveness of primarily virtual pediatric weight management: Rigorous trials are needed to identify effective ways to deliver fully virtual, or mostly virtual, interventions that promote retention, adherence, and healthy weight.…”
