A randomized clinical trial of the effects of parent mentors on early childhood obesity: Study design and baseline data.

ABSTRACT: Few effective community-based interventions exist for early childhood obesity. Parent mentors have been successful as an intervention for other conditions, but have not been used in childhood obesity. We designed an intervention for early childhood obesity using parent mentors and a positive outlier approach to assess potential efficacy, feasibility, and acceptability.This trial enrolled obese (? 95th BMI percentile for age and gender) 2-5-year-old children in a Head Start program and their parents, with allocation to either parent mentors trained in positively deviant behaviors regarding childhood obesity, or community health workers delivering health education on obesity-related behaviors. The primary outcome is body mass index z-score change at the six-month follow-up assessment. Secondary outcomes include feeding behaviors and practices, health-related quality of life, dietary intake, and participation levels.We enrolled three parent mentors and 60 parent-child dyads. The population is 100% Hispanic; 44% of parents speak Spanish as their primary language and 45% were not high-school graduates. Children had a reported median vegetable and fruit intake of 0.3 and 1.1 cups per day, respectively, at baseline, and a median daily screen time of three hours. There was no intergroup difference in quality-of-life scores at baseline. Retention has been high, at 90% in three months.In this randomized trial of the effects of parent mentors on early childhood obesity, parent-child dyads from an underserved, Hispanic population were successfully enrolled through a partnership with a Head Start organization, with a high retention rate.

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.
