Postpartum Weight

Abstract Background Up to 50 % of women with gestational diabetes mellitus (GDM) will receive a diagnosis of type 2 diabetes mellitus (T2DM) within a decade after pregnancy. While excess postpartum weight retention exacerbates T2DM risk, lifestyle changes and behavior modifications can promote healthy postpartum weight loss and contribute to T2DM prevention efforts. However, some women have difficulty prioritizing self-care during this life stage. Efficacious interventions that women can balance with motherhood to reduce T2DM risk remain a goal. The objective of the Moms in Motion study is to evaluate the efficacy of a simple, novel, activity-boosting intervention using ankle weights worn with daily activities during a 6-month postpartum intervention among women with GDM. We hypothesize that women randomized to the 6-month intensity-modifying intervention will (1) demonstrate greater weight loss and (2) greater improvement in body composition and biomarker profile versus controls. Methods This study will be a parallel two-arm randomized controlled trial (n = 160). Women will be allocated 1:1 to an ankle weight intervention group or a standard-of-care control group. The intervention uses ankle weights (1.1 kg) worn on each ankle during routine daily activities (e.g., cleaning, childcare). Primary outcomes include pre- and post-assessments of weight from Visit 2 to Visit 3. Secondary outcomes include body composition, glycemia (2-h, 75 g oral glucose tolerance test), and fasting insulin. Exploratory outcomes include energy expenditure, diet, and psychosocial well-being. Discussion Beyond the expected significance of this study in its direct health impacts from weight loss, it will contribute to exploring (1) the mechanism(s) by which the intervention is successful (mediating effects of energy expenditure and diet on weight loss) and (2) the effects of the intervention on body composition and biomarkers associated with insulin resistance and metabolic health. Additionally, we expect the findings to be meaningful regarding the intervention’s effectiveness on engaging women with GDM in the postpartum period to reduce T2DM risk. Trial registration The ClinicalTrials.gov Identifier, is NCT03664089. The trial registration date is September 10, 2018. The trial sponsor is Dr. Sarah A. Keim.

Abstract Background Nutritional support is essential in the care of critically ill children, since malnutrition in this population is associated to increased morbidity and mortality. Injury in patients admitted to pediatric intensive care units (PICU) results in a catabolic state, with augmented protein breakdown, leading to a negative protein balance. Current recommendations about protein prescription in PICU are fundamentally based on expert opinions, with a minimum threshold of 1.5 g/kg/day of protein, although protein needs could be higher in certain subgroups of patients. The main objective of the present study is to examine if the administration of a protein-enriched infant formula increases the serum levels of total proteins, albumin, prealbumin, transferrin, retinol, and improves nitrogen balance; and to analyze the effect of the high-protein diet on energy expenditure. A secondary objective is to register possible secondary effects of the protein-enriched diet. Methods a multicenter prospective randomized controlled trial (RCT) will be performed in three hospitals. Patients meeting inclusion criteria will be randomly allocated to one of three enteral feeding formula with different protein content. Blood and urine test, nitrogen balance assessment and energy expenditure testing by indirect calorimetry will be performed at the beginning of nutrition regimen and at 24 hours, 72 hours and 5-7 days after initiation. The sample size for this trial is estimated as 90 participants, with approximately 30 participants in each group. The data analysis will be by intention to treat. Discussion this RCT will provide new data about the amount of protein needed to improve levels of serum protein and nitrogen balance, surrogate of protein balance, in critically ill infants receiving enteral nutrition.

ABSTRACT Background Millions of infants are fed breast milk substitutes, and the type of infant formula can impact weight gain patterns. Objective We conducted a randomized controlled trial to determine the direct impact of 2 types of infant formula (cow milk formula, CMF; extensively protein hydrolyzed formula, EHF) on growth and energy balance. Design A racially diverse group of formula-fed infants (n = 113) were randomly assigned to either CMF or EHF from the age of 0.75 to 12.5 mo. At each monthly visit, anthropometric measures were obtained to determine growth z scores and weight gain velocity, and to categorize early weight gain patterns as rapid or nonrapid. Also, diet records were collected to determine energy from formula and other sources. Comprehensive assessments of energy balance (intake, expenditure, loss) were made at 0.75, 3.5, and 12.5 mo. Results Beginning 3 wk after randomization, CMF infants had significantly higher weight, but not length, z scores than did EHF infants, and this persisted after solid foods complemented the formula diet. On average, weight gain velocity from 0.75 to 4.5 mo was within the range of typically growing infants for both groups, yet velocity was 3.9 g/d greater for CMF infants (P = 0.002), who were more likely to be classified as an early rapid weight gainer, than EHF infants (46% compared with 18%; P = 0.007). Early differences in energy intake and fecal loss, yielding greater energy available for deposition among CMF infants, contributed to the differential weight gain patterns. There were no significant differences between the formula treatment groups in total energy expenditure or sleeping energy expenditure. Conclusions Among healthy infants, the type of formula impacted on early rapid weight gain patterns owing to energy intake and loss mechanisms. Research is needed to identify the macronutrients and other compositional constituents in EHF and breast milk that promote satiation and healthy weight gain during sensitive periods of development. This trial was registered at clinicaltrials.gov as: NCT01700205.
