Active clinical trials for "Weight Gain"

The aim of the study was to describe postoperative weight change in adults undergoing surgery for craniopharyngioma and identify preoperative factors associated with it.

The investigators will study the influence of fat cell size/number and adipose function on weight development over very long time periods (years). By comparing fat biopsies obtained at baseline and after >7 years, the investigators will determine the association between adipose morphology/function and changes in weight or development of cardiometabolic complications (e.g. insulin resistance, type 2 diabetes, dyslipidemia and hypertension).

The 'Meir children's sport and health center' runs a multi-disciplinary intervention program for the treatment of overweight and obese children and adolescents. The program includes physical activity, dietary guidelines, medical supervision and behavioral treatment. The participants are routinely weighed once a week, at the same day and time, in order to supervise their progress. According to our experience, the child can predict his weight change, based on his "behavior" in the previous week. To our knowledge the overweight/obese child's ability to predict his weekly weight change, while participating in a multi-disciplinary intervention program, has never been tested.

The aim of this project is to improve the evidence-base regarding lifestyle and mental health symptoms among fitness instructors. A national cohort of fitness instructors will be invited to participate in this study by responding to an online questionnaire. The questionnaire will consist of items regarding exercise, nutrition, eating disorders, the menstrual cycle, depression, anxiety, body dissatisfaction and satisfaction, drive for muscularity and leanness, and experiences of sexual harassment. Findings from this study will provide an evidence-base for initiatives to improve/optimize mental health among fitness instructors, and also in the process of developing fitness centres to a core partner in public health and health promotion work.

This two-year prospective, observational study examines the relationship between habitual short sleep and weight gain, as well as the association between habitual short sleep and behaviors that put people at risk of weight gain. Habitual short sleep is defined as sleeping <6 hours per night on average. Participants will be healthy freshmen college students who are normal weight or overweight. Exclusion criteria include pregnancy, an inability to be ambulatory, currently taking a medication that could influence or interfere with sleep, or reporting a past/current neurological problem, past/current head injury, past/current sleep disorder, current mood, anxiety, or substance use disorder, current psychosis, or current suicidal ideation/plans. Recruitment will be during new student orientations that occur prior to fall semester. Eligibility will be determined using a screening interview, the DSM-5 Self-Rated Level 1 Cross-Cutting Symptom Measure - Adult, and DSM-5 Self-Rated Level 2 measures. Eligible participants will be assessed at baseline (time 1), and 8, 16, and 24 months after Time 1. Sleep, physical activity, food/beverages, substance use, and technology use will be collected daily during each eight day recording period. Sleep will be measured with a sleep monitor, activity will be assessed using an accelerometer, food/beverages will be obtained using the National Cancer Institute's Automated Self-Administered 24-hour Dietary Assessment Tool, and substance use and technology use will be measured via self-report. Participants will attend a session after each recording period to have weight and height measured, be scanned via Dual-energy x-ray absorptiometry (DXA), and complete a packet of questionnaires about demographics, health, sleep quality and beliefs, life events, food cravings, and physical development. It is hypothesized that participants will have different habitual sleep trajectories over time. It is also hypothesized that two particular sleep trajectories (stable habitual short sleep and increasingly shorter habitual sleep across time) will be significantly related to weight gain, increased body fat percent, and weight gain risk behaviors (i.e., increased caloric intake and decreased physical activity). Finally, it is hypothesized that the two sleep trajectories will be significantly associated with higher rates of media and technology use and higher rates of problematic sleep-related beliefs/behaviors.

The hypothesis of the study is that among patients that do not develop overt hypothyroidism after hemithyroidectomy, weight gain is a clinical manifestation of a postoperatively lowered set point of thyroid function - even if the thyroid function is lowered within the laboratory reference range. The investigators refer to this hypothesized condition as individual subclinical hypothyroidism. Thyroid hormones are major regulators of mitochondrial function and subclinical hypothyroidism affects mitochondrial activity. The aim of the study is to examine if a lowered set point of thyroid function after hemithyroidectomy can be measured in the mitochondrial function, the body weight and the basal oxygen consumption.

The purpose of this study is to find determinants of insulin-induced weight gain in type 2 diabetes mellitus Primary objective: To find an association between weight gain after start of insulin therapy and physical activity levels.

During last years, non-caloric sweeteners (NCSs) have been increasingly incorporated into foodstuffs in replacement of sucrose in Chile. This situation has reached a point where it is currently difficult to find sugary foods without NCSs. As a result, the voluntary and involuntary consumption of these additives is growing significantly in the population, increasing the risk of exceeding the acceptable daily intake (ADI), especially for children. This situation is worrying as recent evidence suggests that NCSs are not inert in the body and can trigger adverse metabolic effects. For example, the consumption of beverages with NCSs has been shown to favor the development of obesity and type-2 diabetes in children and adults, and a recent study reported that the intake of NCSs during pregnancy was associated with a greater weight gain of the child at one year. It is likely that certain NCSs pass into the amniotic fluid and that the fetus is exposed to some of these compounds during pregnancy. This situation would persist in the infant through breast milk, as some studies detected sucralose and acesulfame-K in this fluid, even in mothers who claimed not to consume them. However, the real impact of NCS exposure during the neonatal period on the child health has been few studied. Therefore, the aim of this study is to determine the concentration of NCSs in samples of amniotic liquid and breastmilk and to correlate these data with the NCS intake by the mothers. Mothers/children will be classified in quintiles according to the results obtained. In the children from quintiles 1 and 5, we will also study whether neonatal exposure to NCSs may affect the sweet taste threshold and the preferences for this taste, the levels of salivary insulin and the weight gain in the first year. Breastmilk microbiota and child fecal microbiota will be also evaluated.

Clozapine is prescribed to patients with psychosis in whom other treatments have not worked. Research has shown, however, that clozapine may be associated with weight gain and abnormal blood sugar levels in some patients. There is strong evidence to suggest that genetic variation between individuals plays an important role in the development of these side effects in response to the medication. Our research aims to evaluate the effects of two genes and the blood level of clozapine on side-effects such as weight changes and blood sugar levels in patients receiving clozapine treatment. From out-patient clinics in Cwm Taf UHB, the investigators aim to recruit 160 patients who are taking clozapine; collect information/ measurements from recruits relating to size/ weight/ BMI, risk of diabetes and blood samples to measure markers of blood sugar, fat/lipids, clozapine and its breakdown products, blood cells and variants of two specific genes. From this information the investigators will be particularly interested to understand if there is any association between the variation in these two genes with weight gain or changes in blood sugar, in patients taking clozapine.

Prepregnancy body mass index (BMI) and gestational weight gain (GWG) have Significant effects on the risk of pregnancy outcomes such as gestational hypertension disease and gestational diabetes mellitus in singleton pregnancies. This paper is to investigate the relationship between pre-pregnancy body mass index (BMI) and weight gain during pregnancy and pregnancy outcomes in women with twin pregnancy.
