Filter by:The Study of Novel Approaches for Prevention (SNAP) is randomized trial designed to test whether behavioral interventions based on self-regulation can prevent weight gain in young adults (18-35 years; body mass index (BMI) 21-30 kg/m2). Two different self-regulation interventions for weight gain prevention will be compared in this trial; one intervention will focus on making small, consistent, changes in eating and exercise behavior to prevent weight gain or reverse weight gain if it occurs, whereas the other will emphasize larger changes in eating and exercise that occur periodically, with a goal of producing weight loss and thereby providing a buffer against anticipated weight gains. The primary aim of the trial is to test whether the magnitude of weight gain from baseline across an average three-year follow-up differs across the three groups, with the hypotheses that weight gain will be greater in the Control group than in either intervention and greater in the Small Changes than Large Changes group. SNAP-E (Extension) will determine whether the effects of the intervention can be maintained over an additional 3 years (i.e. through a total of 6 years).
Sodium loading during hemodialysis treatment is common and may contribute to increased interdialytic weight gain and hypertension. Excessive use of isotonic saline (containing 0.9% sodium chloride) is one of the factors that may cause sodium loading. During each hemodialysis session, approximately 400 mL of isotonic saline fluid, representing 1.4 grams of sodium, is used to prime and rinse the extracorporeal circuit, and is often administered to the patient. Switching to a non sodium-containing priming and rinsing fluid could allow for removal of the equivalent amount of sodium. Switching to a non sodium-containing solution for the priming and rinsing of the extracorporeal circuit can contribute to increased sodium removal during the dialysis treatment and allow for reduced interdialytic weight gain, reduced thirst, and improved blood pressure control.
Study design: Double blind, randomized, placebo controlled study.The proposed study will consist of two main segments: 1. Segment 1 is aimed to assess the effect of 6-12 months treatment with nutritional supplementation standardized formula, in short and lean prepubertal children on weight SDS, height SDS, BMI SDS and growth velocity 2. Segment 2 is aimed to explore the eating behavior of idiopathic short stature and lean prepubertal children against their sibling who have a normal height and body weight and to find out whether there is a difference in eating patterns and quality of life between idiopathic short stature and lean prepubertal children and children with normal height and body weight Segment 1 Population: 200 subjects and controls will be recruited to segment 1 of the proposed study, 100 at each group. Participants will be recruited from healthy children who will be referred to either the institute for endocrinology or the gastroenterology unit, at Schneider Children's Medical Center for growth assessment, due to low height and weight, in whom, no gastrointestinal morbidity or other underlying cause was found. Methods: Randomization & Blinding: Participants will be randomly assigned either to the intervention group or the placebo control group. Randomization for the two study groups will be made in a ratio of 1:1. Both participants and study team will be blinded to the type of treatment that each patient will receive during the first 6 months of the study. Treatment: Participants in the intervention group will be treated with a nutritional supplementation standardized formula.Participants in the control group will be instructed to consume the same volume of formula as was calculated if they were in the intervention group. Treatment duration: The study will be divided into two treatment periods: 6 months of intervention versus active placebo followed with additional 6 months (an extension period), in which participants at the intervention group will be offered to extend the intervention period and participants at the control arm will be offered to switch to the intervention group. Study Schedule: Follow up visits will take place at 0, 3, 6, 9 and 12 months and will include: 1. Demographic data, medical history and growth data (month 0): Demographic parameters, including birth date, gender, birth weight and length for gestational age, medical history and growth data, including height velocity, parent's and sibling's weight and height will be documented from patient's file. 2. Nutritional assessment 3. Anthropometric assessment (months 0, 3, 6, 9 12): 1. Height without shoes 2. Length 3. Weight with light cloths and without shoes 4. MAC 5. Body mass index (BMI) will be calculated from children's weight and height and age and gender specific BMI SDS will be calculated 6. Body composition assessment using the method of bioelectrical impedance 4. Laboratory parameters (months 0, 6 and 12): 5. Sleeping Questionaire Segment 2: 86 subjects and controls will be recruited to segment 2 of the proposed study Population: Short and lean prepubertal children participating at segment 1 of the study and who are at study entry under 10th percentile in height, when the weight percentile is equal or smaller to the height percentile. Only participants from segment 1 who have siblings with normal height and body weight for age and gender, will be able to participate in segment 2 of the study Control group 1: Sibling of participants in segment 1 of the study, who have a normal height- above 25th percentile and normal BMI for age and gender- above 5th percentile and under 85th percentile. Control group 2: Healthy children from the community who have a normal height above 25th percentile and normal BMI for age and gender above 5th percentile and under 85th percentile Segment 2 of the study will be designed as a case- control study and will focus on the eating patterns, sleeping patterns and quality of life of participants at segment 1 at time 0 month of the study, before the beginning of the nutrition intervention. These findings will be compared to data of a control group, which will be comprised of siblings of participants in segment 1, with normal height and body weight which are matched in age.
Our longitudinal aim is to reduce childhood obesity using our two-pronged intervention program, which includes healthy food choices and increased physical activity initiated during pregnancy and re-instated in the early period after delivery for overweight and obese women. We will accomplish this with our family-based Nutrition and Exercise Lifestyle Intervention Program (NELIP) to promote healthy family living. An intervention targeting school-aged children on the importance of healthy lifestyles occurs too late to prevent childhood obesity and establish lifelong healthy body weights. To break this spiraling cycle of generations of unhealthy body weights in Canadian children, and to reduce the risk of future obesity-related health problems, it is necessary to prevent excessive pregnancy weight gain, high blood sugars in the mother and to promote a healthy lifestyle during pregnancy and early post delivery. With our NELIP team as a cornerstone, and our pilot data already collected with promising results, we foresee an opportunity over the next 3 years to contribute to changing patient care with emphasis on disease prevention and healthy family lifestyle initiation early in life to reverse the trend of childhood obesity. With a solid research-based initiative from the lab to the community by educating health care providers, future health care can be improved by putting prevention-based programs into practice. Healthy women = healthy babies = healthy families = healthy futures!!
Study 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.
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 prevalence of overweight and obesity is increasing among pregnant women in the United States. More than one-third of women of reproductive age in the US are overweight or obese, and two thirds of women gain more weight in pregnancy than is recommended by the Institute of Medicine guidelines. Maternal obesity during pregnancy increases the risk of complications to both mother and child. Minority women (Blacks and Hispanics) have higher rates of overweight and obesity when they become pregnant, experience higher rates of excessive weight gain during pregnancy, and experience higher rates of maternal and neonatal complications after adjusting for sociodemographic characteristics and comorbidities than Caucasian women. Epidemiologic studies indicate that lifestyle modification programs based on diet and exercise are promising approaches in controlling weight gain as well as in preventing type 2 diabetes in populations at risk. We hypothesize that overweight/obese minority women (Blacks and Hispanics) assigned to a culturally-grounded lifestyle intervention program based on diet and moderate exercise will result in higher compliance with Institute of Medicine guidelines for weight gain than women receiving standard care. Such lifestyle modifications should reduce risk of maternal and neonatal complications. We propose 1) to determine whether a lifestyle intervention program, based on diet and moderate physical activity implemented shortly after first recognition of pregnancy, will result in higher compliance with Institute of Medicine guidelines for weight gain compared to women receiving standard care; 2) to determine the occurrence of carbohydrate intolerance and GDM at 24-28 weeks gestation (after the first 10-12 weeks of intervention) and at 6 weeks postpartum between women in the lifestyle intervention group and women receiving standard care; and 3) to explore the impact of the lifestyle intervention on the development of maternal and fetal complications during pregnancy. By limiting excessive weight gain, the lifestyle intervention program may prevent the burden of obesity-related complications during pregnancy and reduce risk of subsequently developing overt diabetes.
The purpose of this study is to determine whether individuals with psychotic spectrum disorders ( Schizophrenia, Schizoaffective disorder,Schizophreniform Disorder, Bipolar Disorder (Type I),Bipolar Disorder (Type II),Major Depressive Disorder With Psychotic Features,Substance-Induced Psychoses,Psychosis Not-Otherwise-Specified (NOS)randomly assigned to a stepped behavioral intervention for the prevention of weight gain will experience less weight gain than individuals who receive usual care. There are several studies that have examined the effect of pharmacological and non-pharmacological behavioural approaches for weight loss in patients with psychosis, however studies examining strategies for prevention of obesity are lacking. This study is an important and novel approach to studying the problem of obesity in those with psychosis.
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.
The purpose of this study is to determine if twice monthly interaction with a registered dietitian from 6-16 weeks gestation through 6 months postpartum will help women who are overweight or obese gain weight during pregnancy closer to the Institute of Medicine (IOM)guidelines and lose weight more effectively within the 6 month postpartum period than those who do not receive twice monthly interaction with a registered dietitian during this period. Overweight/obesity can lead to a number of adverse pregnancy, delivery and birth outcomes, including increased risk of hypertension, eclampsia, and diabetes during pregnancy, miscarriage, premature delivery, birth injuries, neural tube defects, and prenatal death. More than half of women of childbearing age are overweight or are obese. Women of color and low-income women are affected disproportionately. Unfortunately, women know little, if anything, about the impact of overweight and obesity on pregnancy and health care providers are unsure how to effectively address the problem with their patients. A limited number of programs have tested ways to effectively address weight gain management during pregnancy. None have been successful in addressing weight gain in women who are obese or overweight at the start of pregnancy. The 2-year Revere Health Center Pregnancy Weight Management Study will test the feasibility and efficacy of providing pregnant women who are overweight or obese with regular access to a registered dietitian during and after pregnancy to help achieve total weight gain closer to recommended guidelines and to ensure the best outcomes for the mother and her newborn.
