7 Clinical Trials for Various Conditions
The purpose of the study is to understand how mothers think and feel about feeding their babies and putting them to sleep, understand more about programs that can support mothers taking care of babies, and how professionals can be most helpful in helping mothers make decisions about their baby's feeding and sleeping. The overarching goal is to prevent early life obesity and progression to metabolic syndrome in high-risk populations, starting with healthy toddler weights by age 2 years.
Maternal and childhood obesity have dramatically increased and continue to present a significant health problem. Studies show that offspring of overweight (body mass index, BMI \>25-29.9) and obese (BMI ≥30) women are at increased risk of newborn and age 1-year adiposity, and infant adiposity predicts childhood and adult obesity. The investigators hypothesize that infants of overweight/obese (OW/OB) mothers have both relative hyperphagia and are provided human milk with increased caloric composition, leading to obesity. The investigators propose an intervention study to calibrate milk or formula intake in infants of OW/OB mothers so as to avoid overweight infants at 6 months of age.
1) to evaluate treatment fidelity of DRRP: study design, training of interventionists, delivery and receipt of the intervention, and application of the intervention in real-life settings; 2) to identify successful strategies for participant recruitment and maintaining active participation; 3) to collect and analyze preliminary indicators of DRRP's effect on dietary intake, physical activity, stress responses, and body weight; and 4) To evaluate sample representativeness of the target audience, implementation and acceptability of DRRP, and attrition rate.
Childhood obesity is a critical global public health concern. Breastfeeding is the ideal choice for infant nutrition. However, rapid and excess weight gain during infancy predicts later, even among breastfed infants. This risk is higher if mothers are obese and/or diabetic. Composition of bioactive components of breast milk may differ based between mothers who are normal weight (NW), overweight, or who have diabetes. Obesity and Type 2 Diabetes are associated with overall increases in inflammation and oxidative stress, but how breast milk composition is affected remains unknown. The investigators overarching goal is to determine how maternal obesity and Type 2 Diabetes impacts human breast milk composition and how differences in composition may impact infant growth and fat development. The investigators are undertaking a study that follows 20 Normal Weight, 20 Obese, 20 Gestational Diabetic, and 20 Type 2 Diabetic mothers and their infants over the first 4 months of life. The investigators will track infant weight and fat gain and monitor maternal glucose control. The investigators will also collect breast milk samples over the first 4 months and measure concentrations of growth and appetite hormones, cytokines, markers of oxidative stress and nutrient composition in milk. The investigators predict that concentrations of growth-regulatory hormones (insulin and leptin) in addition to the inflammatory cytokines and markers of oxidative stress will be lowest in breast milk from NW mothers, higher in breast milk from obese and gestational diabetic mothers, and highest in Type 2 Diabetic mothers' breast milk. The investigators expect these differences will be most pronounced in the first 2 weeks after birth. The investigators also predict that breast milk concentrations of these biomarkers will be associated with infant fat gain. What the investigators find will help understand how early infant nutrition and growth may affect that child's later risk of obesity.
The purpose of this voluntary research study is to determine if calibrated formula feeding recommendations can promote optimal growth for the first 6 months after birth for mothers with a pre-pregnancy body mass index of 25 or more.
Poor feeding practices during infancy contribute to obesity risk because they interfere with infant feeding self-regulation and appropriate growth patterns as infants transition from human milk and/or formula-based diets to solid foods. The goal of the project is to provide an educational intervention that fosters appropriate maternal responsiveness, feeding styles, and feeding practices via infant-centered feeding.
This study will compare the effects of a low glycemic load versus standard diet for pregnancy on outcomes related to risk for obesity, diabetes, and heart disease in both mother and infant.
