The Effect of Remuneration Schedule on Data Completion and Retention in the Pregnancy Eating Attributes Study (PEAS)

Maximizing data completion and study retention is essential in population research. This study examined the effect of remuneration schedule and data collection modality on data completion and retention in the Pregnancy Eating Attributes Study cohort. Participants (n = 458) completed online surveys and attended six in-person study visits. Initially, remuneration was a prespecified amount per visit, then was changed mid-study to be prorated based on the number of forms completed. Additionally, survey data collection modality was changed to in-person at the sixth study visit. In this secondary data analysis, there was no effect of remuneration schedule on withdrawal rates or time-to-withdrawal. Survey completion was significantly lower under prorated remuneration at the first visit but did not significantly differ at subsequent visits. The lump sum group had significantly greater odds of completely the first and second trimester dietary record (OR = 4.1, OR = 2.6, respectively) then the prorated group but were almost half as likely to complete the dietary record at the 6-month postpartum visit (OR = 0.5). Survey completion at sixth visit was significantly higher for in-person versus online completion (68.6% vs. 93.1%). Findings suggest that remuneration schedule and data collection modality can impact completion of self- reported assessments

Developmental trajectory of appetitive traits and their bidirectional relations with body mass index from infancy to early childhood.

Appetitive traits, including food responsiveness, enjoyment of food, satiety responsiveness and slowness in eating, are associated with childhood body mass index. Change in appetitive traits from infancy to childhood and the direction of causality between appetitive traits and body mass index are unclear. The present study examined the developmental trajectory of appetitive traits and their bidirectional relations with body mass index, from infancy to early childhood. Mothers in the Pregnancy Eating Attributes Study and follow-up (n = 162) reported child appetitive traits using the Baby and Child Eating Behaviour Questionnaires at ages 6 months and 3.5 years, respectively. Standardized body mass index (zBMI) was calculated from child anthropometrics. Cross-lagged panel models estimated bidirectional relations between appetitive traits and zBMI. Food responsiveness, satiety responsiveness and slowness in eating increased from infancy to early childhood. In cross-lagged panel models, lower infant satiety responsiveness (B ± SE = -0.45 ± 0.19, p = .02) predicted greater child zBMI. Infant zBMI did not predict child appetitive traits (p-values >.36). From infancy to early childhood, appetitive traits may amplify. Appetitive traits, particularly satiety responsiveness, appear to influence body mass index during this period, suggesting early intervention targeting these traits may reduce childhood obesity

Associations of Appetitive Traits and Parental Feeding Style with Diet Quality During Early Childhood.

BackgroundAppetitive traits and parent feeding styles are associated with body mass index in children, yet their associations with child diet quality are unclear.ObjectiveThe objective was to examine relations of appetitive traits and parental feeding style with diet quality in 3.5-year-old children.DesignThe study was a secondary, cross-sectional analysis of data from Sprouts, a follow-up study of the Pregnancy Eating Attributes Study (PEAS). Birthing parents completed the Child Eating Behavior Questionnaire, Caregiver's Feeding Styles Questionnaire, and proxy 24-hour dietary recalls for their children from February 2019 to December 2020.Participants/settingParticipants were 162 birthing parents (early pregnancy BMI ≥18.5 kg/m2 and absence of pre-existing diabetes, any medical condition contraindicating study participation, self-reported eating disorder, and medications that could affect diet or weight) and their children living in North Carolina.Main outcome measuresHealthy Eating Index-2015 (HEI-2015) total scores were calculated.Statistical analyses performedPath modeling was conducted using PROC CALIS with full information maximum likelihood (FIML) to account for missing data (ResultsA 1-SD greater food fussiness was associated with a 2.4-point lower HEI-2015 total score [p = .02, 95% CI (-4.32, -0.48)] in children. When parental feeding style was authoritarian, a 1-SD greater food responsiveness was associated a 4.1-point higher HEI-2015 total score [p = .007, 95% CI (1.12, 7.01)] in children. When parental feeding style was authoritative, a 1-SD greater slowness in eating was associated with a 5.8-point lower HEI-2015 total score [p = .01, 95% CI (-10.26, -1.33)] in children.ConclusionsParental feeding style may modify the association of appetitive traits with diet quality in young children. Future research could determine whether matching parent feeding styles to child appetitive trait profiles improves child diet quality

Adolescent Bullying Involvement and Perceived Family, Peer and School Relations: Commonalities and Differences Across Race/Ethnicity

Although bullying is recognized as a serious problem in the U.S., little is known about racial/ethnic differences in bullying risk. This study examined associations between bullying and family, peer, and school relations for White, Black and Hispanic adolescents

Pregnancy eating attributes study (PEAS): a cohort study examining behavioral and environmental influences on diet and weight change in pregnancy and postpartum

Abstract Background The rising prevalence of maternal overweight/obesity and excessive gestational weight gain poses a serious public health concern due to the contribution of these factors to increased risk of negative health outcomes for both mother and child. Scant intervention research has indicated moderate short-term improvement in maternal diet and gestational weight gain, with little evidence of long-term behavior change, in parallel with findings from interventions outside of pregnancy. Recent laboratory-based findings from neuroscience implicate aberrant reward processing of food at the brain level (“food reward sensitivity,” the between-individual variation in the response to food stimuli) as a contributor to eating beyond energy needs. However, scant research has examined the influence of these processes on weight change in population-based settings, and the relevance of these processes to pregnancy-related weight change has not been explored. The purpose of the Pregnancy Eating Attributes Study (PEAS) is to examine the role of food reward sensitivity in maternal diet and weight change during pregnancy and postpartum. The study examines the interplay of food reward sensitivity with behavioral control, home food environment, and related aspects of eating behavior in the context of weight-related biomedical, psychosocial, genetic and behavioral factors including physical activity, stress, sleep and depression. Methods Women of varying baseline weight status (n = 450) are enrolled early in pregnancy and followed, along with their infants, until 1 year postpartum. Assessments occur during each trimester of pregnancy, and postpartum at approximately 2 months, 6 months, 9 months and 12 months. Maternal food reward, self-control, home food environment, eating behaviors, dietary intake, health behaviors, and anthropometrics are assessed along with maternal and infant clinical and biological data, infant anthropometrics, and feeding practices. Primary exposures of interest include food reward sensitivity, behavioral control, and home food environment. Primary outcomes include gestational weight gain, postpartum weight retention and maternal diet quality. Discussion With increasing evidence suggesting the relevance of food reward sensitivity for understanding eating behavior, PEAS aims to advance understanding of the determinants of eating behavior during pregnancy, informing future interventions for improving maternal diet and weight change, and leading to improved maternal and child health and weight trajectories.

High and low glycemic index mixed meals and blood glucose in youth with type 2 diabetes or impaired glucose tolerance.

This cross-over pilot study tested blood glucose response to low and high glycemic index meals in 12 obese youth with type 2 diabetes or impaired glucose tolerance. Participants demonstrated significantly lower mean daytime blood glucose and a trend toward lower variability, suggesting a clinically relevant impact of reducing glycemic index

Cardiovascular Biomarkers in Association with Dietary Intake in a Longitudinal Study of Youth with Type 1 Diabetes

Despite cardioprotective effects of a healthy diet in the general population, few studies have investigated this relationship in individuals with type 1 diabetes, who are at elevated risks of cardiovascular disease (CVD) due to hyperglycemia. The objective of this study was to examine the association of CVD biomarkers with overall diet quality, as measured by the Healthy Eating Index-2015 (HEI-2015), and its dietary components in youth with type 1 diabetes. Youth with type 1 diabetes (n = 136, 8–16.9 years) were enrolled in an 18-month behavioral nutrition intervention trial. Dietary intake from three-day diet records, CVD biomarkers (total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C); triglycerides (TG), C-reactive protein (CRP), 8-iso-prostaglandin-F2alpha (8-iso-PGF2α), systolic and diastolic blood pressure (SBP and DBP, respectively), and glycated hemoglobin (HbA1c) were assessed at baseline, 6, 12 and 18 months. Linear mixed-effects models estimated associations of dietary intake with CVD biomarkers, adjusting for HbA1c and other covariates. Separate models estimated associations of time-varying change in dietary intake with time-varying change in CVD biomarkers. HEI-2015 was not associated with CVD biomarkers, but whole grain intake was inversely associated with TC, HDL-C and DBP, and a greater increase in whole fruit intake was associated with lower DBP. Added sugar, saturated fat and polyunsaturated fat were positively related to serum TG, HDL-C, and DBP, respectively. Findings suggest that the intake of specific dietary components, including whole grains, whole fruits, added sugar and PUFA, may influence cardiometabolic health in youth with type 1 diabetes, independent of glycemic control

Acceptability of lower glycemic index foods in the diabetes camp setting

OBJECTIVE: To determine the acceptability of lower glycemic index (GI) foods served at diabetes camp. DESIGN: Crossover design of standard and lower GI menus. SETTING: Three consecutive 5-day diabetes camp sessions. PARTICIPANTS: 140 youth, age 7-16, with type 1 or 2 diabetes. INTERVENTION: A standard camp cycle menu was reformulated to include 2 1/2 days of standard foods and 2 1/2 days of lower GI foods. MAIN OUTCOME MEASURES: Youth provided satisfaction ratings after meals and snacks using measures designed for this study. Observations of food consumption were conducted on a random sample of youth for each meal. ANALYSIS: Descriptive analyses and t-tests were conducted to assess differences in satisfaction with and consumption of standard and lower GI foods. RESULTS: Lower GI foods served at dinner and for snacks received satisfaction ratings equal to standard foods (dinner: 3.68 lower GI versus 3.79 standard, P = .30; snacks: 3.74 lower GI versus 3.79 standard, P = .60). Lower GI foods served at breakfast and lunch received lower, though very acceptable, ratings (breakfast: 3.76 lower GI versus 4.04 standard, P \u3c .01; lunch: 3.64 lower GI versus 3.88 standard, P = .01). Consumption of all meals was acceptable. No differences occurred in the frequency of high or low blood sugars between standard and lower GI days. CONCLUSIONS AND IMPLICATIONS: Higher quality carbohydrates may be provided to youth in institutional settings while maintaining sufficient levels of acceptability; specific findings are instructive for designing efforts to increase their consumption

Effect of varying glycemic index meals on blood glucose control assessed with continuous glucose monitoring in youth with type 1 diabetes on basal-bolus insulin regimens

OBJECTIVE: The purpose of this study was to test the effect of high glycemic index (HGI) and low glycemic index (LGI) meals on blood glucose levels using continuous blood glucose monitoring in youths with type 1 diabetes. RESEARCH DESIGN AND METHODS: A total of 20 youths on basal-bolus regimens consumed macronutrient-matched HGI and LGI meals 1 day each in a controlled setting in varying order following consumption of a standardized evening meal. Medtronic MiniMed Continuous Glucose Monitoring Systems were used to assess blood glucose (BG) profiles. RESULTS: Participants demonstrated significantly lower daytime mean BG, BG area \u3e180 mg/dl, and high BG index when consuming LGI meals but no differences for daytime BG area \u3c70 mg/dl, daytime low BG index, or any nighttime values. Significantly more BG values \u3c80 mg/dl were treated on LGI days. CONCLUSIONS: Findings indicate that consumption of an LGI diet may reduce glucose excursions, improving glycemic control
