Evaluating a Small Change Approach to Preventing Long Term Weight Gain in Overweight and Obese Adults...
ObesityPrevention of Weight GainObesity is a major risk factor for disease and a public health problem. Recent information suggests that while it is possible for most overweight adults to lose a substantial amount of weight, maintaining the weight loss for any extended time (2 to 3 years) is very difficult. This is because trying to maintain big changes in exercise and/or eating behaviour is very difficult in today's environment that makes sustain big changes in behaviour (Example: eat allot less or exercise allot more) very hard. In fact at this time health professionals are unsure of how best to help overweight adults maintain big behavioral changes for long periods of time. In response, we propose that making smaller changes in eating and exercise habits every day may be possible in today's environment and if so, small weight changes may be possible to maintain for long periods of time. This study is designed to assess whether making small changes in eating and exercise behavior will be associated with sustained weight loss over three (3) years. The results of the study may have important implications for development of public health messages and clinical guidelines for prevention and treatment of obesity through small changes in both exercise and eating habits.
Hormonal Regulation of Body Weight Maintenance
ObesityWeight Loss5 moreThe investigators here propose to perform a collaborative clinical research effort including a randomized controlled trial investigating the mechanisms of weight maintenance and their relation to a lifestyle intervention in children, adolescents and adults. The detailed investigation and analysis of the variability and dynamics of the endocrine circuits responding to a negative energy balance and weight loss will be accompanied and enhanced by specific clinical projects targeting peripheral and central-nervous aspects of hormonal counter-regulation after weight loss. Mechanisms of endocrine counter-regulation and potential therapeutic approaches will be studied.
Can Dietitians Reduce Interdialytic Weight Gain in at Risk Hemodialysis Patients Through Tailored...
End Stage Renal Disease Requiring HemodialysisThe purpose of this project is to understand if more frequent education of dialysis patients (patients with kidney failure who get their blood cleaned and fluid removed by a machine instead of their kidneys) on reducing sodium intake reduces the amount of fluid weight that patients gain between dialysis sessions. Patients who usually gain more fluid than is considered ideal will be recruited for this project. Because all patients gain different amounts to start, data will be collected for 3 months while the patients receive their usual amount of dietitian education. Then the patients will receive intensive (2x/month) education on reducing sodium intake from the dietitian and the same data will be collected to see if they gain less after the education. After 3 months of intensive education, data will be collected for one more month to see if patients keep gaining less or if they go back to their old patterns.
Gestational Weight Gain in Primary Care
Gestational Weight GainExcess weight gain in pregnancy is linked to a number of adverse outcomes for mothers and their offspring, and in 2011, 59 % of women in Nova Scotia gained weight in excess of recommendations. A number of factors influence how much weight a woman gains, including lack of knowledge, age, the number of previous pregnancies she's had, smoking, ethnicity, income, and education. Although a clinician's advice also plays a role, simply giving advice does not necessarily translate into patient behaviour change. On the other hand, advice that is given through a patient-centred approach is significantly associated with increased patient acceptance of and adherence to recommendations, and increased intentions and attempts at behaviour change. In addition, this approach has been shown to decrease costs to the health care system. Patient-centredness can measured from the perspective of the clinician, an observer, or the patient. Research suggests that the patient's perspective of patient-centredness is the perspective most significantly associated with improved health outcomes. Clinicians avoid discussing weight-related matters for a number of reasons, including a lack of time and general discomfort in raising the subject. There are some tools that can address some of these barriers, and example being the "5As of Obesity Management". This tool is based on principles of behaviour change science and patient-centredness. Pilot data on the use of this tool showed a two-fold increase in the initiation of weight-related discussions between clinicians and their patients. Our team was instrumental in the development, dissemination and initial evaluation of this tool, and Dr. Piccinini-Vallis has recently led a national multidisciplinary endeavor to adapt it to pregnancy, which has resulted in the "5As of Healthy Pregnancy Weight Gain" tool. It is now time to evaluate whether the use of this tool is acceptable to clinicians and whether its use translates into any patient outcomes.
Healthy Lifestyles for Mentally Ill People Who Have Experienced Weight Gain From Their Antipsychotic...
DiabetesObesity1 moreThis program aims to help Veterans who take antipsychotic medications lose weight. We use a program based on the American Diabetes Association's "Diabetes Prevention Program," and we have modified it to fit the lifestyles of people with mental illness. All participants are educated about nutrition and cutting down fat intake, how and when to exercise, and the causes of diabetes and how to prevent it. Participants must be Veterans who live within one hour of the Long Beach, West Los Angeles, Sepulveda, or West Los Angeles VA hospitals.
The wEight Management in Renal Transplant Online Study (ExeRTiOn)
Kidney Transplant; ComplicationsObesity3 moreThe primary aim of this project is to create an online weight management tool (Physical activity, weight management and cognitive behavioral therapy) to prevent significant weight gain following kidney transplantation. Designing the online interactive weight management resource for kidney transplant patients will involve patient and health care professional input through Qualitative methodology such as 'Think-Aloud' interviews and one-to-one semi-structured interviews. This online resource will be called "exertion" and will be created by the research team, with technical support from the Software Company (SPIKA). Results from this study will refine the resource, and lead to a study application for a randomized controlled feasibility trial where we plan to test the "exertion" online application. Therefore this project has potential to influence clinical practice for kidney transplant recipients. It will allow patients, who may not have routine access to physio or dietetic input to address weight gain with support. A study flow chart summarizing the project can be found below.
Promoting Healthy Weight Gain During Pregnancy
Weight GainStudy goal is to determine whether behavioral lifestyle intervention during pregnancy can reduce the number of women who exceed the Institute of Medicine recommendations for weight gain during pregnancy. It is hypothesized that the intervention will reduce the number of women who exceed weight gain guidelines relative to standard care. The investigators also expect the intervention to reduce the proportion of women exceeding weight gain guidelines in both normal weight and overweight groups.

1/2-MC4R Genotype and Pediatric Antipsychotic Drug- Induced Weight Gain
High Risk MC4R GenotypeLow Risk MC4R Genotype1 moreWe will conduct a 12-week, randomized open label study, comparing usual care (UC) antipsychotic treatment (aripiprazole, quetiapine, risperidone) with ziprasidone (ZIP) in children and adolescents aged 13-18 years old. Patients will have 10 days or less lifetime antipsychotic exposure and be in clinical need for antipsychotic treatment for a pediatric psychiatric disorder with FDA indication for antipsychotic use, i.e., bipolar mania, schizophrenia-spectrum disorders, and irritability associated with autistic disorder. In addition, we will also include youth fulfilling research diagnostic criteria for severe mood dysregulation (SMD). Randomization will be stratified by high vs. low genetic risk for antipsychotic-induced weight gain based on MC4R genotype and the primary outcome will be weight change from baseline to endpoint between ZIP and UC antipsychotic treatment in each of the two genotype groups. As detailed below, other metabolic and cardiac safety parameters will also be measured and compared across treatments in each of the genotype groups.
