Active clinical trials for "Weight Gain"

The purpose of this trial is to investigate the mechanisms leading to weight gain during CPAP treatment for obstructive sleep apnea (OSA).

The purpose of this online follow-up study is to investigate health app use in pregnant women and through a pilot intervention trial investigate whether the addition of evidence-based information on health-promoting lifestyle delivered via the health app has an effect on lifestyle habits (gestational weight, diet quality and physical activity) during pregnancy.

The purpose of this research study is to test whether delivery of medically tailored meals (meals designed specifically to be healthy) can be used to help reduce high blood sugar after delivery of a baby. Participants will be recruited and consented during the third trimester of pregnancy but will begin study activities after delivery. Participants will complete a series of questionnaires on demographics, health history, home environment, overall and financial stress, plans for weight loss and infant feeding, and food insecurity. Participants will also be asked to wear continuous glucose monitors for two separate 14-day periods (within 2 weeks of delivery and at 3 months). All participants will receive weekly emails with educational videos and 3 virtual visits with a member of the study team and will also be randomly assigned to an intervention or comparison group. In the intervention, participants will receive weekly meal deliveries of 10 pre-prepared meals from Providence Community Kitchen (local company in Winston-Salem, NC) that are calorically restricted and appropriate for post-partum women with a history of gestational diabetes and who may be breast-feeding. Women in the control condition will receive written resources on self-care, nutrition, and physical activity appropriate for post-partum women who had gestational diabetes.

Marrow adipocytes have been identified as a component of the bone marrow micro-environment. Evidence exists suggesting that marrow fat plays an important physiologic role in both bone mineral and energy metabolism in humans. The investigators will study the effects of acute weight gain and acute nutritional deprivation on energy homeostasis and bone mineral metabolism by examining marrow adiposity, peripheral fat depots and bone microarchitecture. The study will include two ten day inpatient study visits. Participants will eat a high calorie diet for 10 days, followed by a 13-18 day stabilization period at home, and then return for a ten day fast.

This research study is a sub-study within the Behavioral Activation for Smoking Cessation and the Prevention of Post-Cessation Weight Gain main study (NCT02906787). Participants who are eligible for the main study and meet certain MRI (Magnetic Resonance Imaging) related study criteria (i.e. conditions) may also elect to complete a series of computer tasks inside a standard, closed MRI scanner to examine changes in brain activity associated with the smoking cessation counseling that participants will receive in the main study. In total, participants will be asked to complete 2, one-hour fMRI scans: 1 before completing their first counseling session and 1 during the final 7 days of the scheduled 8-week nicotine patch treatment period.

The purpose of this study is to determine whether a new infant cereal has an effect on weight gain and intestinal microbiota compared to a standard cereal in healthy infants .

Cobedding consists of associating twins in a common cocoon in order to maintain links developed in utero and reduce the stress of premature birth. The aim of this randomized, controlled prospective study is to compare efficacy (in term of newborn daily weight gain) and safety of cobedding versus single-bedding of preterm twins.

Primary Objective: To test the effect of pramlintide on body weight in clozapine- and olanzapine-induced weight gain in persons with schizophrenia who are currently taking either drug; measures of the metabolic syndrome will be evaluated as well.

RATIONALE: Physical activity may prevent or reduce weight gain in women receiving chemotherapy for early stage breast cancer. PURPOSE: This randomized phase I/II trial is studying physical activity to see how well it works compared with usual care to prevent or reduce weight gain in women with stage I or stage II breast cancer undergoing chemotherapy.

Energy-yielding fluids induce weaker appetitive and compensatory dietary responses than energy-matched semi-solids or solids. This is problematic because the high and increasing contribution of energy from beverages in the diet may enhance positive energy balance and weight gain. The prevailing view of the overweight/obesity problem is that it stems from a small, sustained positive energy balance. It follows then that only small changes, perhaps manipulations in the rheological characteristics of the diet, will be required to correct the problem. Certain populations that are more prone to weight gain may benefit from such manipulations. Obese individuals have a higher beverage intake and experience greater weight loss with reductions in beverage intake. Further, there is evidence that obese individuals consume more energy after a liquid pre-load than their lean counterparts, yet there is no difference in energy intake after a solid load. In contrast, habitual exercisers have been shown to have an increased accuracy of short-term regulation of food intake at meals following liquid preloads. A better understanding of the mechanisms by which beverages and energy-matched solid food forms elicit differential appetitive and dietary responses in these populations needed. This research will attempt to identify the influence of physical fitness and body fat on the ability to compensate for the energy content of solid and liquid preloads by reduction in energy intake at a subsequent ad libitum meal (i.e., acute compensation) and over the course of the day (i.e., short-term compensation). Furthermore, this study will examine the cognitive contribution to differential responses to energy-matched beverage and solid food forms and the effects of mastication on appetite, GI transit, glycemic response, and selected endocrine responses.
