Effect of a Responsive Parenting Educational Intervention on Childhood Weight Outcomes at 3 Years of Age: The INSIGHT Randomized Clinical Trial.

ABSTRACT:

Importance

Rapid growth and elevated weight status in early childhood increase risk for later obesity, but interventions that improve growth trajectories are lacking.

Objective

To examine effects of a responsive parenting intervention designed to promote developmentally appropriate, prompt, and contingent responses to a child's needs on weight outcomes at 3 years.

Design, setting, and participants

A single-center randomized clinical trial comparing a responsive parenting intervention designed to prevent childhood obesity vs a home safety intervention (control) among 279 primiparous mother-child dyads (responsive parenting group, 140; control group, 139) who enrolled and completed the first home visit from January 2012 through March 2014 with follow-up to age 3 years (completed by April 2017).

Interventions

Research nurses conducted 4 home visits during infancy and annual research center visits. The responsive parenting curriculum focused on feeding, sleep, interactive play, and emotion regulation. The control curriculum focused on safety.

Main outcomes and measures

The primary outcome was body mass index (BMI) z score at 3 years (z score of 0 represents the population mean; 1 and -1 represent 1 SD above and below the mean, respectively). BMI percentile at 3 years was designated previously as the primary outcome. Secondary outcomes included the prevalence of overweight (BMI ≥85th percentile and <95th percentile) and obesity (BMI ≥95th percentile) at 3 years.

Results

Among 291 mother-child dyads randomized, 279 received the first home visit and were included in the primary analysis. 232 mother-child dyads (83.2%) completed the 3-year trial. Mean age of the mothers was 28.7 years; 86% were white and 86% were privately insured. At age 3 years, children in the responsive parenting group had a lower mean BMI z score (-0.13 in the responsive parenting group vs 0.15 in the control group; absolute difference, -0.28 [95% CI, -0.53 to -0.01]; P = .04). Mean BMI percentiles did not differ significantly (47th in the responsive parenting group vs 54th in the control group; reduction in mean BMI percentiles of 6.9 percentile points [95% CI, -14.5 to 0.6]; P = .07). Of 116 children in the responsive parenting group, 13 (11.2%) were overweight vs 23 (19.8%) of 116 children in the control group (absolute difference, -8.6% [95% CI, -17.9% to 0.0%]; odds ratio [OR], 0.51 [95% CI, 0.25 to 1.06]; P = .07); 3 children (2.6%) in the responsive parenting group were obese vs 9 children (7.8%) in the control group (absolute difference, -5.2% [95% CI, -10.8% to 0.0%]; OR, 0.32 [95% CI, 0.08 to 1.20]; P = .09).

Conclusions and relevance

Among primiparous mother-child dyads, a responsive parenting intervention initiated in early infancy compared with a control intervention resulted in a modest reduction in BMI z scores at age 3 years, but no significant difference in BMI percentile. Further research is needed to determine the long-term effect of the intervention and assess its efficacy in other settings.

Project description:ImportanceRapid infant weight gain is associated with later obesity, but interventions to prevent rapid infant growth and reduce risk for overweight status in infancy are lacking.ObjectiveTo examine the effect of a responsive parenting (RP) intervention on infant weight gain between birth and 28 weeks and overweight status at age 1 year.Design, setting, and participantsThe Intervention Nurses Start Infants Growing on Healthy Trajectories (INSIGHT) study is an ongoing randomized clinical trial comparing an RP intervention designed to prevent childhood obesity with a safety control. The study includes primiparous mother-newborn dyads (n = 291) and was conducted at the Penn State Milton S. Hershey Medical Center, Hershey, Pennsylvania, in addition to home visits. Enrollment was initiated in January 2012, and evaluable population analyses for this study were conducted between April 2015 and November 2015.InterventionsAt 2 weeks post partum, initial intervention materials appropriate to the assigned treatment group were mailed to the participant's home. Research nurses conducted home visits at 3 weeks, 16 weeks, 28 weeks, and 40 weeks, and a research center visit occurred at 1 year. The Intervention Nurses Start Infants Growing on Healthy Trajectories curriculum included messages about infant feeding, sleep hygiene, active social play, emotion regulation, and growth record education. The control group received a developmentally appropriate home safety intervention also delivered by nurse home visitors.Main outcomes and measuresConditional weight gain from birth to 28 weeks was calculated. General linear models examined intervention effect on conditional weight gain. The intervention's effect on infant weight-for-length percentiles was tested using analysis of variance. Logistic regression compared the odds of overweight status (weight for length ≥95th percentile) at 1 year as a function of conditional weight gain.ResultsOf the mothers included in the study, 246 were white (88%), 260 were non-Hispanic (93%), 210 were married (75%), and 201 were working full time (72%) at time of enrollment. The mean conditional weight gain score was lower among infants in the RP group compared with the control group (-0.18; 95% CI, -0.36 to -0.001), reflecting that the RP infants gained weight more slowly than control group infants (0.18; 95% CI, 0.02-0.34); this effect did not differ by feeding mode (predominantly fed breast milk or not). Infants in the RP group also had lower mean weight-for-length percentiles at 1 year than infants in the control group (57.5%; 95% CI, 52.56%-62.37% vs 64.4%; 95% CI, 59.94%-69.26%; P = .04) and were less likely to be overweight at age 1 year (5.5% vs 12.7%; P = .05).Conclusions and relevanceAn RP intervention is associated with reduced rapid weight gain during the first 6 months after birth and overweight status at age 1 year.Trial registrationclinicaltrials.gov Identifier: NCT01167270.

Project description:BACKGROUND:What, when, how, how much, and how often infants are fed have been associated with childhood obesity risk. The objective of this secondary analysis was to examine the effect of a responsive parenting (RP) intervention designed for obesity prevention on parents' infant feeding practices in the first year after birth. METHODS:Primiparous mother-newborn dyads were randomized to the Intervention Nurses Start Infants Growing on Healthy Trajectories (INSIGHT) Study RP intervention or child safety control. Research nurses delivered intervention content at home at infant age 3-4, 16, 28, and 40 weeks, and at a research center at 1 year. RP feeding guidance advised feeding that was contingent (i.e., feed in response to hunger and satiety signs, alternatives to using food to soothe), and developmentally appropriate (i.e., delaying introduction of solids, age-appropriate portion sizes). Infant feeding practices (i.e., bottle use, introduction of solids, food to soothe) were assessed by phone interviews and online surveys and dietary intake was assessed using a food frequency questionnaire. RESULTS:RP mothers were more likely to use of structure-based feeding practices including limit-setting (p?<?0.05) and consistent feeding routines (p?<?0.01) at age 1 year. RP group mothers were less likely to use non-responsive feeding practices such as pressuring their infant to finish the bottle/food (p?<?0.001), and using food to soothe (p?<?0.01), propping the bottle (p?<?0.05) assessed between 4 and 8 months, and putting baby to bed with a bottle at age 1 year (p?<?0.05). Few differences were seen between groups in what specific foods or food groups infants were fed. CONCLUSIONS:Anticipatory guidance on RP in feeding can prevent the use of food to soothe and promote use of more sensitive, structure-based feeding which could reduce obesity risk by affecting how and when infants are fed during the first year.

Project description:BACKGROUND:Sedentary behaviors, including screen time, in childhood have been associated with an increased risk for overweight. Beginning in infancy, we sought to reduce screen time and television exposure and increase time spent in interactive play as one component of a responsive parenting (RP) intervention designed for obesity prevention. METHODS:The Intervention Nurses Start Infants Growing on Healthy Trajectories (INSIGHT) study is a randomized trial comparing a RP intervention with a safety control intervention. Primiparous mother-newborn dyads (N = 279) were randomized after childbirth. Research nurses delivered intervention content at infant ages 3, 16, 28, and 40 weeks and research center visits at 1 and 2 years. As one component of INSIGHT, developmentally appropriate messages on minimizing screen time, reducing television exposure in the home, and promoting parent-child engagement through interactive play were delivered. Mothers self-reported their infant's screen time at ages 44 weeks, 1, 1.5, 2 and 2.5 years; interactive play was reported at 8 and 20 weeks and 2 years. RESULTS:More RP than control parents reported their infants met the American Academy of Pediatrics' no screen time recommendation at 44 weeks (53.0% vs. 30.2%) and at 1 year on weekdays (42.5% vs. 27.6%) and weekends (45.5% vs. 26.8%), but not after age 1 year. RP mothers and RP children had less daily screen time than controls at each time point (p ≤ 0.01). Fewer RP than control group mothers reported the television was ever on during infant meals (p < 0.05). The frequency of tummy time and floor play did not differ by study group; approximately 95% of infants spent time in restrictive devices (i.e. swing) at 8 and 20 weeks. At 2 years of age, there were no study group differences for time children spent in interactive play. CONCLUSION:From infancy to early childhood, the INSIGHT RP intervention reduced screen time and television exposure, but did not increase the frequency or amount of interactive play.

Project description:BackgroundAlthough previous work has shown that children with older siblings tend to have poorer diet quality, no study has directly compared diets of infant siblings.ObjectiveThe goals of this analysis were to examine birth-order differences in dietary intake between firstborn (FB) and secondborn (SB) siblings, and to determine whether a responsive parenting (RP) intervention modified birth-order effects on diet.MethodsThe Intervention Nurses Start Infants Growing on Healthy Trajectories (INSIGHT) study randomly assigned first-time mothers to an RP intervention, which included guidance on feeding, sleep, soothing, and interactive play, or control. INSIGHT mothers who delivered a second child enrolled in an observation-only study of their SB infant (SIBSIGHT). Mothers completed FFQs for both children at ages 6 (n = 97 sibling pairs) and 12 (n = 100) mo. FB compared with SB intake of food groups of interest were compared, and the moderating effect of the RP intervention on birth-order differences was tested using generalized linear mixed models.ResultsThough FBs and SBs had similar diets, more FBs than SBs consumed 100% fruit juice at both 6 (13.8 compared with 3.2%, P = 0.006) and 12 mo (46.0 compared with 32.0%, P = 0.01). SBs consumed fruit more frequently (FB 2.8 compared with SB 3.2 times/d, P = 0.01), and were more likely to consume fried potatoes (FB 38.4 compared with SB 57.6%, P = 0.0009) and processed meats (FB 43.0 compared with SB 58.0%, P = 0.02) than FBs at 12 mo. There were no differences by birth order in intake of sweets, snacks, or sugar-sweetened beverages at 12 mo. At 12 mo, RP-group SBs ate vegetables more times per day (3.2) than control SBs (2.2, P = 0.01). RP-SBs also consumed a greater variety of vegetables (10.2) than control-SBs (7.9, P = 0.01).ConclusionsBirth order is not consistently associated with healthy or unhealthy infant dietary intake. However, an RP intervention delivered to first-time mothers may benefit subsequent infants' vegetable intake. This trial was registered at clinicaltrials.gov as NCT01167270.
