Подробное описание
Rationale: The focus of this project is to develop a strategy to combat medication associated weight gain, the most problematic side effect of the newer antipsychotic medications. Improvements in long-term health outcomes might then be expected to change quality of life, promote treatment adherence, rehabilitative potential, and decrease resource utilization.
Procedures:
Half of the patients will randomized to the behavioral weight loss program (Lifestyle Balance Program) and do the following: Meet with their psychiatrist and a nutritionist who will go over diet recommendations with the patient Given a 7% weight loss goal Assisted in obtaining a 500 calorie reduction per day Asked to exercise for at least 30 min/day, at least 5 days a week Maintain weekly food and exercise diaries Be quizzed on their knowledge of healthy eating habits and nutrition
The other half of the patients will be randomized to "Usual Care" and will:
Receive pamphlets about Lifestyle Balance, starting exercise, and general nutritional information regarding food pyramids and the amount of calories in fast foods.
Be encouraged to exercise and eat a healthy diet Not receive classes on nutrition or exercise Be seen on the same schedule as the experimental group, in order to equalize contact time.
After six months, if patients in the "usual care group" wish to participate in the more rigorous behavioral weight loss program they will be given that opportunity.
Visits:
Time Line:
Each subject will be followed for one year. Healthy Lifestyles courses will take eight weeks to complete. Visits will be monthly for the remaining 12 months Enrollment: 120 patients Course of study: October 2005-October 2008
At Beginning and Termination:
Informed Consent (at start of study only) Psychiatric interviews and assessments Physical Examination Framingham risk assessment for cardiovascular disease Electrocardiogram Lipid Profile, fasting glucose, Hemoglobin A1C
At Each Visit:
Vitals, weight, waist circumference, BMI, and % Fat Food and exercise diaries will be reviewed
At Month One and Month Six:
Lipid Profile, fasting glucose, Hemoglobin A1C Electrocardiogram Psychiatric assessments
At Month Nine:
Lipid Profile, fasting glucose, Hemoglobin A1C Electrocardiogram
Clinical Care:
All patients will continue their clinical care with their current psychiatrist and general physician. Medications will not be manipulated for the purpose of this study.
Incentives:
The group participating in the behavioral intervention program will receive rewards for achieving weight loss goals and be given incentives such as a pedometer and Slimfast meal replacements.

Change in Predicted Trajectory of Mean BMI Per GLMM Analysis

General Linear Mixed Model (GLMM) is a full information maximum likelihood approach that permits inclusion of all available data and provides unbiased parameter estimates even if there are missing data under the condition that data are missing at random.
The GLMM approach assumes that every patient is on a specific trajectory over time and that both the slope and the shape of this trajectory are a potential function of group membership or other person-level covariates.
Using a likelihood ratio test, we compared different options to model these trajectories and found a linear model, which assumes that the same rate of change is maintained over the whole study, provided a good fit to the data.
We used a linear model of the average rate of change over time (slope) for all comparisons.
To illustrate the magnitude of difference between slopes for major outcomes, we report the estimated difference at 12 months between two hypothetical participants with identical baseline characteristics.
