Filter by:The purpose of this study is to determine whether school gardens influence children's dietary intake, nutritional knowledge, and other outcomes.
The purpose of the GRECO study were to: a) to provide national data on overweight and obesity prevalence in a representative sample of primary schoolchildren aged 10-12 years old, b) to identify those socio-economic, demographic factors, as well as dietary and physical activity habits and familial characteristics that are associated with childhood and preadolescent overweight and obesity, c) to identify lifestyle and dietary patterns that are associated with elevated blood pressure levels and dietary sodium intake.
This project examines behavioral and household characteristics associated with food purchasing patterns.
The primary objective of this study is to test effectiveness of an environmental intervention designed to encourage healthy food intake during meals. It is hypothesized that fruit, vegetable, whole grain, lean protein, and low-fat dairy consumption will increase during the intervention. It is also hypothesized that nutrition knowledge, attitudes, and behaviors will change as a result of the intervention. The findings from this study will provide insight into the applicability of this intervention in military dining facilities.
The purpose of the study is to identify lifestyle factors associated with PCOS and understand how diet and activity levels impact features of PCOS. The secondary aim is to examine psychosocial factors (e.g., health beliefs) of women with PCOS.
While most of the research on integrated approaches of occupational health and safety and worksite health promotion to date has focused on manufacturing settings, employment is shifting to the service sector. Within this sector, health care employs over 12 million workers, and is the second fastest growing industry in the U.S. economy. In contrast to workers in other industries, rates of occupational injuries and illnesses among health care workers have increased over the past decade. The purpose of this study is to lay the foundation for integrated interventions in health care through examination of the associations of worker health outcomes and risks on and off the job with work policies and practices and to address the prevalent issues of musculoskeletal disorders (MSDs), particularly low back pain disability (LBPD), and health promotions through physical activity among patient care workers. The specific aims of this study are: 1. To estimate the efficacy and determine the feasibility of an integrated intervention, addressing both health protection and health promotion in order to reduce MSD symptoms and improve health behaviors among healthcare workers. We will assess between-group differences in MSD symptoms, health behaviors, including physical activity, and a set of secondary outcomes, including unplanned absence, reported injuries, worker compensation claims and costs, turnover and retention, intention to leave the job, and work-role function. This study will explore the working hypothesis that: Workers employed at baseline in patient-care units receiving the intervention will report greater reductions in their MSD symptoms (primary outcome) and greater improvements in health behaviors, compared with workers employed at baseline in units assigned to the Usual Care control group. 2. To determine the factors in the work environment which contribute over time to reductions in MSD symptoms and improvements in safe and healthy behaviors. (1) The work environment, work organization, and psychosocial factors, measured in our current study, will be associated with changes in workers' health behaviors and health outcomes between the assessments in the current and proposed studies; (2) Improvements in the work environment over time will be associated with improvements in workers' health behaviors and health outcomes. We will conduct multilevel modeling analysis to evaluate the simultaneous effects of worker-level and unit-level factors on MSD symptoms and safety and health behaviors.
This pilot study will test the feasibility and potential effectiveness of a novel approach to improve food choices by employees about what to eat for lunch. The intervention involves the testing of an on-line pre-ordering food program with nutritional information linked to a hospital cafeteria. In this study, the investigators use positive reinforcement of feedback and price discounts during the intervention phase, and then withdraw those components in order to assess the potential for changes to be retained after the study is over. The study draws on principles from the field of behavioral economics and behavioral change. The investigators test the effectiveness of the intervention with 30 employees (study participants) who are overweight or obese. Based on a recent screening of over 5600 Einstein employees, 66% of those screened were identified as either overweight or obese. There are 3 phases to the trial: baseline (P1), 4 week intervention, (P2) and tapering (intervention without reinforcement) (P3). Participants are randomized to one of two groups (intervention and wait-listed controls). Our primary hypotheses are that: 1. Participants will purchase lunches with fewer calories during the intervention compared to baseline. 2. Participants will purchases lunches with fewer calories in the tapering phase compared to baseline. Secondary hypotheses include that, compared with baseline, participants will order lunches with less fat. Changes in participant weight based on self selected goals, and in a measure of mindful eating will also be investigated. The investigators expect that participant adherence will be associated with improved outcomes compared to those who are less adherent.
Nuclear factor kappa B (NF-κB) pathway and oxidative stress participate in endothelial dysfunction, which is one of the causes of preeclampsia. Among the human antioxidant mechanisms there are the enzymes catalase (CAT), glutathione peroxidase (GPx) and superoxide dismutase (SOD). Our aim was to measure NF-κB and oxidative stress in pregnant women submitted to an individualized diet during pregnancy.
The purpose of this study is to determine if the phase of the menstrual cycle (opposed versus unopposed estrogen phase) affects eating behavior, including types of foods preferred, wanting/desire for specific foods, and perception of hunger.
Compared to solid foods, the nutritional energy of drinks may bypass the appetite regulation leading to obesity development. Although drinks sweetened with aspartame are available the anticipated positive effect of these drinks on obesity development has not been convincing. However, the mechanisms linking drinks intake to obesity are yet to be clarified. The investigators aim is to investigate the long-term effects of intake of soft drinks, milk and water. The study is a parallel, intervention trial with 80 overweight, healthy volunteers. They will be randomly selected to drink one liter a day of one of the four drinks for six months. The objectives are changes in numerous circulating metabolic risk factors, changes in body weight, anthropometric data and fat distribution (measured by DEXA, MRI and MR-spectroscopy). The investigators expect to clarify the mechanisms linking drinking habits to obesity development and provide scientifically based nutritional guidelines.
