A randomized, home-based, childhood obesity intervention delivered by patient navigators.

ABSTRACT: Although Colorado is perceived as a healthy state, in 2010, 14.1 % of children aged 2-5 were overweight and 9.1 % were obese. Despite the high prevalence of obesity in this population, evidence to support particular strategies to treat obese preschoolers is lacking. The efficacy of home-based, childhood obesity interventions to reduce a child's body mass index is inconclusive. However, this model uniquely provides an opportunity to observe and intervene with the home food and activity environment and engage the entire family in promoting changes that fit each family's unique dynamics.Eligible participants are children aged 2-5 years who attended a well-child care visit at a Denver Health Community Health Service clinic within 12 months prior to recruitment and on that visit had a body mass index (BMI) >85th percentile-for-age. Participants are randomly recruited at study inception and allocated to the intervention in one of five defined 6-month stepped wedge engagements; the delayed intervention groups serves as control groups until the start of the intervention. The program is delivered by a patient navigator at the family' home and consists of a 16-session curriculum focused on 1) parenting styles, 2) nutrition, and 3) physical activity. At each visit, a portion of curriculum is delivered to guide parents and children in selecting one goal for behavior change in each of three work areas to work on during the following week. The primary study outcome measure is change in BMI z-score from baseline to post-intervention period.This childhood obesity study, innovative for its home-based intervention venue, provides rich data characterizing barriers and facilitators to healthy behavior change within the home. The study population is innovative as it is focused on preschool-aged, Latino children from low-income families; this population has not typically been targeted in obesity management assessments. The home-based intervention is linked to clinical care through update letters and assessment of the program's impact to the child's medical providers. Informing primary care providers about a child's accomplishments and challenges, allows the clinician to support the health weight effort when seeing families during subsequent clinical visits.ClinicalTrials.gov NCT02024360 Registered December 21, 2013.

Project description:BackgroundObesity is a major problem in the United States, particularly among socio-economically disadvantaged Latino and Black children. Effective interventions that can be disseminated to large numbers of at-risk children and their families are needed. The goals of the Early Childhood Obesity Prevention Program (ECHO) are to examine the 12-month efficacy of a primary obesity prevention program targeting the first year of life that is delivered by home visitors and that engages mothers as agents of change to modify their own behavior and their infant's behavior through education and skill-building around nutrition, physical activity, and wellness, and then "echoes" her training with linkages to neighborhood programs and resources.Methods/designSix family centers located in low-income neighborhoods in Hartford, CT were randomized into control and intervention neighborhoods. Fifty-seven mothers were recruited either prenatally or shortly after delivery into the Nurturing Families Network home visitation program; 27 lived in a control neighborhood and received the standard home visitation program and 30 lived in an intervention neighborhood and received both the standard home visitation program and the ECHO intervention. The intervention increases maternal skills in goal-setting, stimulus control and problem-solving, engages family members to support changes, links mothers to neighborhood resources and is embedded in the standard home visitation program. ECHO targets include breastfeeding, solids, juice and sugar-sweetened beverages, routines for sleep and responding to infant cues, television/screen time, and maternal diet and physical activity. We hypothesize that infants in ECHO will have been breastfed longer and exclusively, will have delayed introduction of solids and juice, have longer sleep duration, decreased television/screen time and a lower weight for length z-score at 12 months, and their mothers will have greater fruit and vegetable consumption and higher levels of physical activity.DiscussionECHO will provide important information about whether an enhanced behavior change curriculum integrated into an existing home visitation program, focused on the mother as the agent of change and linked to neighborhood resources is effective in changing energy balance behaviors in the infant and in the mother. If effective, the intervention could be widely disseminated to prevent obesity in young children.Trial registrationClinicalTrials.gov NCT02052518 January 30, 2014.

Project description:BackgroundCurrent recommendations for intensive behavioral interventions for childhood obesity treatment do not account for variable participant attendance, optimal duration of the intervention, mode of delivery (phone vs. face-to-face), or address obesity prevention among young children. A secondary analysis of an active one-year behavioral intervention for childhood obesity prevention was conducted to test how "dose delivered" was associated with body mass index z-score (BMI-Z) across 3 years of follow-up.MethodsParent-child pairs were eligible if they qualified for government assistance and spoke English or Spanish. Children were between three and 5 years old and were at risk for but not yet obese (BMI percentiles ≥50th and < 95th). The intended intervention dose was 18 h over 3-months via 12 face-to-face "intensive sessions" (90 min each) and 6.75 h over the next 9 months via 9 "maintenance phone calls" (45 min each). Ordinary least-squares multivariable regression was utilized to test for associations between dose delivered and child BMI-Z immediately after the 1-year intervention, and at 2-, and 3-year follow-up, including participants who were initially randomized to the control group as having "zero" dose.ResultsAmong 610 parent-child pairs (intervention n = 304, control n = 306), mean child age was 4.3 (SD = 0.9) years and 51.8% were female. Mean dose delivered was 10.9 (SD = 2.5) of 12 intensive sessions and 7.7 (SD = 2.4) of 9 maintenance calls. Multivariable linear regression models indicated statistically significant associations of intensive face-to-face contacts (B = -0.011; 95% CI [- 0.021, - 0.001]; p = 0.029) and maintenance calls (B = -0.015; 95% CI [- 0.026, - 0.004]; p = 0.006) with lower BMI-Z immediately following the 1-year intervention. Their interaction was also significant (p = 0.04), such that parent-child pairs who received higher numbers of both face-to-face intensive sessions (> 6) and maintenance calls (> 8) were predicted to have lower BMI-Z. Sustained impacts were not statistically significant at 2- or 3-year follow-up.ConclusionsIn a behavioral intervention for childhood obesity prevention, the combination of a modest dose of face-to-face sessions (> 6 h over 3 months) with sustained maintenance calls (> 8 calls over 9 months) was associated with improved BMI-Z at 1-year for underserved preschool aged children, but sustained impacts were not statistically significant at 2 or 3 year follow-up.Clinical trial registrationThe trial was registered on ClinicalTrials.gov (NCT01316653) on March 16, 2011, which was prior to participant enrollment.

Project description:ImportanceEarly childhood obesity disproportionately affects Native American communities. Home visiting is a promising strategy for promoting optimal infant growth in this population.ObjectiveTo assess the impact of a brief home-visiting approach, Family Spirit Nurture (FSN), on sugar-sweetened beverage (SSB) consumption, responsive parenting and infant feeding practices, and optimal growth through 12 months post partum.Design, setting, and participantsThis study was a 1:1 randomized clinical trial comparing FSN with an injury prevention education control condition in a reservation-based community. Participants were Navajo mothers 13 years or older with infants younger than 14 weeks recruited between March 22, 2017, and May 18, 2018, and followed up through 12 months post partum. Intent-to-treat analyses were conducted.InterventionsThe 6-lesson FSN curriculum, delivered 3 to 6 months post partum by Navajo paraprofessionals, targeted optimal responsive and complementary feeding practices and avoidance of SSBs. The control group received 3 injury prevention lessons.Main outcomes and measuresPrimary outcomes established a priori were infant SSB consumption and responsive parenting and complementary feeding practices (responsive feeding scale, age at complementary food introduction, and percentage of mothers who introduced complementary food to infants at 6 months of age or older). The secondary outcome was the effect of the intervention on infant body mass index z scores (zBMIs).ResultsA total of 134 Navajo mothers of infants younger than 14 weeks were enrolled in the randomized clinical trial, including 68 (mean [SD] maternal age at enrollment, 27.4 [6.4] years) in the intervention group and 66 (mean [SD] maternal age at enrollment, 27.5 [6.1] years) in the control group. Intervention participants reported statistically significantly lower infant SSB consumption through 12 months post partum (mean [SE], 0.56 [0.12] cups per week in the intervention group and 1.78 [0.18] cups per week in the control group; incidence rate ratio, 0.31; 95% CI, 0.19-0.50). Improvements in responsive feeding practices were observed through 9 months post partum (mean [SE], 3.48 [0.07] in the intervention group and 3.22 [0.08] in the control group) (difference, 0.26; 95% CI, 0.06-0.47); statistical significance was lost at 12 months post partum. Age at which the infant was given first food was younger in the intervention group (mean [SE] age, 4.61 [0.21] months in the intervention group and 5.28 [0.23] months in the control group) (difference, -0.67; 95% CI, -0.04 to -1.29). Infants in the intervention group had lower zBMI at 6 and 9 months compared with those in the control group (mean [SE] at 9 months, 0.27 [0.14] in the intervention group and 0.81 [0.14] in the control group; difference, -0.54; 95% CI, -0.94 to -0.14). The 12-month between-group difference was meaningful but not statistically significant (mean [SE], 0.61 [0.16] in the intervention group and 1.07 [0.20] in the control group; difference, -0.46; 95% CI, -0.92 to 0.01).Conclusions and relevanceInfants of Native American mothers who participated in a home-visiting intervention had substantially lower SSB consumption and improvements in responsive feeding practices and infant zBMI scores, suggesting the intervention is effective for promoting healthy infant feeding and growth.Trial registrationClinicalTrials.gov Identifier: NCT03101943.

Project description:Background:Home-based lifestyle behaviour interventions show promise for treating and preventing childhood obesity. According to family theories, engaging the entire family unit, including parents, to change their family behaviour and dynamics may be necessary to prevent the development of childhood obesity. However, little is known about how these interventions, which may change the family dynamics and weight-related behaviours of parents, affect weight outcomes in parents. Our objective was to examine the effect of a pilot home-based childhood obesity prevention intervention on measures of anthropometrics and body composition in Canadian parents. Methods:Forty-four families with children aged 1.5-5?years were randomized to one of three groups: 4 home visits with a health educator, emails, and mailed incentives (4?HV); 2 home visits, emails, and mailed incentives (2?HV); or general health emails (control). Both the 2?HV and 4?HV intervention were conducted over a period of 6?months. Body composition and anthropometric outcomes were measured at baseline and at 6?months and 18?months from baseline. Results:In parents with baseline body mass index (BMI)???25?kg/m2, the 2?HV group had significantly lower body mass and waist circumference at 6-month (CI = -5.85,-0.14 kg;-5.82,-0.30 respectively) and 18-month follow-up (CI?=?-7.57,-1.21?kg;-9.30,-2.50?cm respectively) when compared to control, and significantly lower BMI at 18-month follow-up when compared to control (CI?=?-2.59,-0.29?kg/m2). In parents with baseline BMI?<?25?kg/m2, the 4?HV group had significantly lower percentage fat mass (CI?=?-3.94,-0.12%), while the 2?HV group had significantly lower body mass (CI?=?-2.56,-0.42?kg) and BMI (CI?=?-0.77,-0.08?kg/m2) at 6-month follow-up, both compared to control; these effects were not maintained at 18-month follow-up. Conclusions:This study provides support that a home-based childhood obesity prevention intervention may improve weight outcomes among parents. Future research should explore how home-based interventions influence family behaviour and dynamics to impact weight outcomes in children and their parents.
