Project description:Because early life growth has long-lasting metabolic and behavioral consequences, intervention during this period of developmental plasticity may alter long-term obesity risk. While modifiable factors during infancy have been identified, until recently, preventive interventions had not been tested. The Intervention Nurses Starting Infants Growing on Healthy Trajectories (INSIGHT). Study is a longitudinal, randomized, controlled trial evaluating a responsive parenting intervention designed for the primary prevention of obesity. This "parenting" intervention is being compared with a home safety control among first-born infants and their parents. INSIGHT's central hypothesis is that responsive parenting and specifically responsive feeding promotes self-regulation and shared parent-child responsibility for feeding, reducing subsequent risk for overeating and overweight.316 first-time mothers and their full-term newborns were enrolled from one maternity ward. Two weeks following delivery, dyads were randomly assigned to the "parenting" or "safety" groups. Subsequently, research nurses conduct study visits for both groups consisting of home visits at infant age 3-4, 16, 28, and 40 weeks, followed by annual clinic-based visits at 1, 2, and 3 years. Both groups receive intervention components framed around four behavior states: Sleeping, Fussy, Alert and Calm, and Drowsy. The main study outcome is BMI z-score at age 3 years; additional outcomes include those related to patterns of infant weight gain, infant sleep hygiene and duration, maternal responsiveness and soothing strategies for infant/toddler distress and fussiness, maternal feeding style and infant dietary content and physical activity. Maternal outcomes related to weight status, diet, mental health, and parenting sense of competence are being collected. Infant temperament will be explored as a moderator of parenting effects, and blood is collected to obtain genetic predictors of weight status. Finally, second-born siblings of INSIGHT participants will be enrolled in an observation-only study to explore parenting differences between siblings, their effect on weight outcomes, and carryover effects of INSIGHT interventions to subsequent siblings.With increasing evidence suggesting the importance of early life experiences on long-term health trajectories, the INSIGHT trial has the ability to inform future obesity prevention efforts in clinical settings.NCT01167270. Registered 21 July 2010.

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.

Project description:We investigated genome-wide DNA methylation of newly emerged queens, newly emerged workers, adult nurses, adult foragers and adult reverted nurses using comprehensive high throughput arrays for relative methylation (CHARM) We used custom Nimblegen microarrays We isolated genomic DNA from newly emerged queens, newly emerged workers, adult continuous nurses, adult continuous foragers and adult reverted nurses hybridized to custom-designed Nimblegen microarrays (CHARM arrays). Multiple brains were pooled for each sample and used for the genome-wide DNA methylation analysis.

Project description:<p>This is a study of the oral and gut microbiome of 226 mother-child dyads enrolled in the INSIGHT (Intervention Nurses Start Infants Growing on Healthy Trajectories) study. INSIGHT is a randomized, controlled trial comparing a responsive parenting intervention designed for the primary prevention of childhood obesity against a control. </p> <p>The microbiome portion of the study was designed to investigate the relationship between a cross-sectional view of the child's microbiome (at two years of age) and the patterns of growth between birth and 2 years. These first-born children were deeply studied in this time period with data collected on a wide variety of variables including mode of delivery, sex, weight and height (collected at 7 time points), medication usage, diet information, and maternal health information (gestational weight gain, gestational diabetes, smoking during pregnancy). Microbiome samples from the child (buccal swab and stool sample) and their mother (buccal swab) were collected at the child's 2-year clinical research visit. </p>

Project description:In the present study, we sought to determine the degree of circadian misalignments of hormonal and transcriptional rhythms with the timing of sleep-wake behavior on days off in day-shift and night-shift hospital nurses. We conducted a genome-wide microarray analysis on RNA isolated from PBMCs to examine individual variability of transcriptional rhythms.
