The role of lifestyle modification in dysmetabolic syndrome management.

Lifestyle modification should be the primary therapeutic intervention in individuals with the dysmetabolic syndrome, given the fact that obesity, unhealthy diet, and physical inactivity are primary underlying risk factors for its development. Most individuals with the dysmetabolic syndrome need to lose weight through dietary changes and increases in physical activity. Modest weight losses may significantly improve all aspects of the syndrome. Because individuals differ in their lifestyles, tailoring interventions to meet the specific needs of each person will maximize the chances of success. Assessment of the individual with the dysmetabolic syndrome involves quantification of obesity, diets and dietary patterns, physical activity, emotional problems, and motivation. To help individuals make lifestyle changes, a number of behavior modification strategies have shown good efficacy. These strategies include a tailored problem-solving intervention, involving goal-setting, self-monitoring, stimulus control, cognitive restructuring, stress management, relapse prevention, social support, and contracting. The frequency of self-monitoring is an especially important strategy for continued success. Research studies have clearly demonstrated the power of lifestyle modification for long-term behavioral change. Lifestyle modification appears effective in delaying or preventing the development of the dysmetabolic syndrome.

Designing "lifestyle interventions" with the brain in mind.

The central hypothesis examined in this issue is that insulin resistance promotes maladaptive brain function and contributes to reduced neuronal plasticity, potentially accelerating brain aging. Therefore, if we were to prevent or treat insulin resistance, through weight loss and exercise, cognitive function would be improved. In this article, we argue that successful interventions influencing these outcomes depend upon overriding maladaptive neurobiology. This maladaptation may have developed over the course of the lifespan through interaction with modern environments. Furthermore, we emphasize the need to take this emergent neurobiology into account when designing interventions.

Need for lifestyle intervention: how to begin.

The metabolic syndrome is the fastest growing disease entity in the world. Prevention and effective treatment emphasize lifestyle intervention, including healthful diet, physical activity, and pharmacologic agents to target specific risk factors. Weight loss improves all aspects of the metabolic syndrome and is a primary intervention target. Effective weight management also helps prevent the development of the metabolic syndrome. Lifestyle change strategies--including setting reasonable goals, raising awareness, confronting barriers to change, managing stress, cognitive restructuring, preventing relapse, and providing support--are the keys to long-term success.

Treatment of the metabolic syndrome: the impact of lifestyle modification.

Along with the increasing prevalence of obesity comes a constellation of metabolic derangements: dyslipidemias, hypertension, insulin resistance, and glucose intolerance, as well as increased prothrombotic and inflammatory markers. The association of these factors has been termed the "metabolic syndrome" and increases the risk of developing cardiovascular disease. Aside from pharmaceutical therapy, lifestyle modification is necessary to aggressively treat this syndrome in its entirety. This involves a holistic approach of behavioral counseling, education, increased physical activity, and dietary modification. Even modest weight loss (7% to 10% of body weight) results in decreased fat mass, blood pressure, glucose, low-density lipoprotein, and triglyceride levels. These benefits can also translate into improved long-term outcome, especially if weight loss and lifestyle alterations are maintained. However, the remaining challenge is how to promote long-term adherence to a healthier, more active lifestyle and avoid reversion to old habits.

Behavioral interventions for obesity.

Because of the increased risk of comorbid conditions such as type 2 diabetes, hypertension, and osteoarthritis, and the high health care costs associated with obesity, researchers and clinicians continually search for low-cost and effective treatments for weight loss and weight maintenance. In this article we provide an overview of the principles of behavior modification as applied to the treatment of obesity, examine the benefits of augmenting behavioral interventions with pharmacotherapy, and review the use of less-traditional applications of behavior modification in the treatment of obesity, specifically Internet interventions, meal replacements, and telephone interventions. Based on our review, we conclude that these less-traditional approaches can be used effectively to apply the principles of behavior modification, specifically stimulus control and self-monitoring, to obese patients. Future directions for research are outlined, which include examining the use of nontraditional behavioral interventions with children and the development of culturally sensitive interventions for racial and ethnic minority populations.

Sibutramine and the management of obesity.

Sibutramine is a selective serotonin and noradrenaline re-uptake inhibitor approved for the long-term management of obesity. Its primary mechanism of action is increased satiety, although some evidence also suggests increased energy expenditure could play a role in sibutramine-induced weight loss. It has established general efficacy in long-term trials, with clinically-approved doses of 10 and 15 mg. Sibutramine has also been studied in a number of unique populations, including obese controlled hypertensives, diabetics and ethnic minorities, further establishing its effectiveness. However, it does have a consistent effect of increasing blood pressure and pulse. Thus, blood pressure and heart rate should be monitored in patients using sibutramine and it may not be applicable in obese patients with significant cardiovascular disease.

Validity and reliability of the general well-being schedule with northern plains American Indians diagnosed with type 2 diabetes mellitus.

The General Well-being Schedule is a brief indicator of subjective feelings of psychological well-being and distress. It is easy to administer, reliable, and valid, although its validity with American Indians has not been established. This study then assessed reliability, validity, and factor structure for a sample of 88 diabetic American Indians, who sought care for diabetes at an Indian Health Service hospital. Cronbach alpha was .89. A factor analysis indicated four dimensions. Adequate concurrent and divergent validity were noted in association with scores on the Beck Depression Inventory-Second Edition, the depression scale on the Symptom Checklist-90-Revised, and Family-Adaptation, Partnership, Growth, Affection, & Resolve. These results suggest that the General Well-being Schedule is a reliable and valid measure of general well-being for this population of American Indians.

Migration history, health behaviors, and cardiovascular disease risk factors in overweight Mexican-American women.

PURPOSE: This research examined whether the migration history of overweight Mexican-American women had an independent effect on cardiovascular risk factors, or whether it was mediated by health behavior changes. DATA AND METHODS: Cross-sectional data from 390 overweight, non-diabetic Mexican-American women (aged 18 to 65 years), all recruited from Starr County, Texas, were used for this analysis. Migration history was inferred from birthplaces of subjects and relatives, and length of residence in the United States. Health behaviors included tobacco and alcohol use, sleeping, exercise, and dietary practices. The cardiovascular disease risk factor variables (CDRFVs) studied were plasma glucose, abdominal obesity, blood pressures, and blood lipids. A migration history score (MHS) was developed from factor analysis, almost equally contributed to by the 9 migration history variables. Healthy habits were defined by 6 variables, and 3 factors (blood pressures, lipids/glucose, and body fat/glucose) were used for the CDRFVs. FINDINGS AND CONCLUSION: MHS was correlated positively with socioeconomic status, and negatively with family stress. Older women had healthier drinking and sleeping habits. Women with a higher migration history score exhibited poorer exercise habits, and increased blood pressures. After adjusting for the effect of healthy exercise habits on blood pressures, the impact of migration history on blood pressures became non-significant (P>.05), leading to the conclusion that healthy exercise behaviors mediated the negative relationship of MHS with blood pressures. Age was independently positively correlated with all CDRFVs. Age also weakly moderated the negative relationship of MHS and healthy exercise habits.

Depression predicts disability in long-term chronic pain patients.

PURPOSE: Investigators have examined factors that predict treatment outcome and disability status in chronic pain patients, including psychopathology and personality characteristics with equivocal results. The purpose of this study was to evaluate the usefulness of personality characteristics, depression, and personality disorders in predicting disability status in pain patients with long-term follow-up. The setting was a rehabilitation hospital in Southern Sweden. METHOD: Subjects were 184 pain patients (mean age = 43.4 (10.8) years; 72.8% female) who had no more than 365 sick leave days (Mean sick leave days = 132.7 (128.2)) prior to the baseline personality and psychiatric evaluation. The baseline evaluation consisted of a psychiatric interview that included the administration of the Structured Clinical Interview for DSM-IV Screen Questionnaire (SCID-II), the Montgomery-Asberg Depression Rating Scale (MADRS), and the Karolinska Scales of Personality (KSP). Disability status was assessed by insurance record review a minimum of two-and-a-half years after baseline evaluation. RESULTS: Multivariate logistic regression suggests that age (OR = 1.09, 95% CI = 1.02-1.18; p = 0.013), number of sick leave days prior to evaluation (OR= 1.01, 95% CI= 1.01-1.02; p = 0.018), and baseline diagnosis of depression significantly predicted subsequent disability status (OR = 7.04, 95% CI = 1.15-42.93; p = 0.034). Baseline personality traits and the diagnosis of a personality disorder were not useful predictors of disability status in our sample. CONCLUSIONS: These data suggest that depression, but not personality disorders characteristics, was an important disability predictor in chronic pain patients with extended follow-up.

Exercise augments the effects of cognitive-behavioral therapy in the treatment of binge eating.

OBJECTIVE: To evaluate the effects of adding exercise and maintenance to cognitive-behavior therapy (CBT) for binge eating disorder (BED) in obese women. METHOD: One hundred fourteen obese female binge eaters were randomized into four groups: CBT with exercise and maintenance, CBT with exercise, CBT with maintenance, and CBT only. RESULTS AND DISCUSSION: Eighty-four women completed the 16-month study. Subjects who received CBT with exercise experienced significant reductions in binge eating frequency compared with subjects who received CBT only. The CBT with exercise and maintenance group had a 58% abstinence rate at the end of the study period and an average reduction of 2.2 body mass index (BMI) units (approximately 14 lb). BMI was significantly reduced in the subjects in both the exercise and maintenance conditions. The results suggest that adding exercise to CBT, and extending the duration of treatment, enhances outcome and contributes to reductions in binge eating and BMI.
