Evaluation of a "nondieting" stress reduction program for overweight women: a randomized trial

PURPOSE: Determine if a "nondieting" intervention focused on intensive training in eliciting the relaxation response enhances health outcomes compared with nondieting interventions without such training. DESIGN: Randomized trial with follow-up at 10 weeks, 4 months, and 12 months. SETTING: General community. SUBJECTS: Total of 225 overweight and obese women with at least one other cardiovascular risk factor. INTERVENTIONS: Three 10-week nondieting interventions: a group program (P1) focused on intensive training in techniques for eliciting the relaxation response (n = 60), a group program (P2) focused on healthy eating and physical activity (n = 61), and a self-guided, mail-delivered version of P2 (P3; n = 101). MEASURES: The Revised Symptom Checklist measured psychological distress, the Medical Symptoms Checklist measured the experience of medical symptoms, and the Health-Promoting Lifestyle Profile measured a range of lifestyle behaviors. Self-efficacy for low-fat eating intuitive eating, and body mass index were also assessed. ANALYSIS: An intention-to-treat analysis was used. RESULTS: At 12 months, P1 produced statistically greater improvements in stress management behaviors and medical symptom discomfort and was the only program to significantly improve self-efficacy for low-fat eating. In P1, the effect sizes for reductions in depression (0.75) and interpersonal sensitivity (0.85) were large. At 12 months, mean weight was unchanged. CONCLUSION: Inclusion of intensive relaxation response training in a nondieting program for overweight women enhanced stress management and medical symptoms outcomes but not weight outcomes.     

Evaluation of a stress management course in adult education centres in rural Australia

OBJECTIVE: To investigate whether attending a six-week stress management course in a rural adult education centre is effective in reducing participants' levels of stress, anxiety and depression. DESIGN: Repeated measures design using self-report measures of stress, anxiety and depression at commencement and completion of a six-week stress management course, and six months post-completion follow up. SETTING AND PARTICIPANTS: One hundred and thirty-two adults (age range 18-73 years) living in a rural community who self-enrolled in the stress management course at adult education centres. INTERVENTION: The course consisted of six weekly group sessions. Each two-hour session conducted by mental health professionals, included teaching cognitive behavioural strategies targeted at reducing individual symptoms of stress. MAIN OUTCOME MEASURES: Comparative analysis of pre- and post-test and six-month follow up on measures of stress (Stress Symptom Checklist), anxiety and depression (Hospital Anxiety and Depression Scale). Results: Results indicated a significant reduction in stress symptoms (F(7,90) = 34.92, P < 0.001), anxiety and depression (F(3,95) = 87.92, P < 0.001) from course commencement to course completion. These improvements were sustained six months after course completion for stress symptoms (F(11,65) = 22.40, P < 0.001), anxiety and depression (F(5,73) = 41.78, P < 0.001). CONCLUSION: Findings demonstrate the stress management course is an effective community intervention in a rural community. Challenges for future implementation of the program are discussed.     

Evaluation of a Mindfulness-Based Stress Reduction (MBSR) program for caregivers of children with chronic conditions

OBJECTIVES: Given the demands of caring for chronically ill children, it is not surprising that caregivers often experience high levels of chronic stress. A Mindfulness-Based Stress Reduction (MBSR) program may offer relief to these caregivers by providing tools for self-care and heath promotion that otherwise may be lacking. METHODS: MBSR classes were offered without restriction to parents of children attending various clinics at a large urban children's medical centre. Caregivers completed the Profile of Mood States (POMS) and Symptoms of Stress Inventory (SOSI) both before and after program participation. RESULTS: Forty-four caregivers participated in one of seven group MBSR sessions that were offered between August 2001 and February 2004. Most were mothers of children with special needs and various chronic conditions, who had been diagnosed an average of 7 years previous. Prior to the intervention, caregivers reported very high levels of stress and mood disturbance. These decreased substantially over the 8-week program, with an overall reduction in stress symptoms of 32% (p < .001), and in total mood disturbance of 56% (p < .001). CONCLUSIONS: This brief MBSR program for caregivers of chronically ill children was successful in significantly decreasing substantial stress symptoms and mood disturbance. Further studies would benefit from using more rigorous methodology and applying the program to other groups of chronically stressed caregivers.     

Life-style intervention at the worksite--reduction of cardiovascular risk factors in a randomized study

OBJECTIVES: This study tested a feasible method for screening for cardiovascular risk at the worksite and investigated the effects of a long-term comprehensive program of life-style intervention to prevent cardiovascular disease. METHODS: Employees in the public sector filled out a self-administered questionnaire with questions on social, medical, and work-related factors. The respondents numbered 454 (80%). A score sum for cardiovascular risk was calculated (range 1-20, median 7.0), and the 128 subjects with a sum above 8 were invited to a health examination including blood sampling. Thereafter the subjects were invited to participate, following randomization, in a comprehensive, 18-month, life-style intervention program to improve cardiovascular risk or in a control group. RESULTS: The intervention group significantly decreased body mass index, diastolic blood pressure, heart rate, low-density lipoprotein (LDL) cholesterol, and smoking habits during the intervention. The initially elevated serum cortisol, as a marker of stress reaction, normalized in the intervention group. In the control group LDL cholesterol also decreased, but the glucose and triglyceride levels increased, and smoking habits were unchanged. Sick days for a given period decreased after 1 year in the intervention group but not in the control group. CONCLUSIONS: Several cardiovascular risk factors can be improved and morning serum cortisol normalized during a long-term life-style intervention program with a randomized design using a worksite population of middle-aged subjects. The use of a 2-step screening program, with an initial questionnaire followed by a health check of subjects with elevated risk, is feasible for worksite settings.     

Two-year outcome of coping skills training, group support and information for spouses of alcoholics: a randomized controlled trial

AIM: To evaluate three different intervention programmes for spouses of alcoholics. METHODS: 39 spouses of alcoholics (36 women and 3 men) with an average age of 47 years (ranging from 23 to 60 years) were randomly assigned to one of the three interventions: Coping Skills Training, Group Support, and Information. Follow-up interviews were conducted 12 and 24 months after completing the programme. Coping Behaviour Scale, Symptom Checklist 90 (SCL-90), Hardship Scale and AUDIT at admission and at follow-up were compared. 38 of the 39 spouses completed the 24-month follow-up examination. RESULTS: Improvements of coping behaviour, psychiatric symptoms and hardship noted at the 12-month follow-up examination were still evident in all groups at the 24-month follow-up examination. The three groups scored similarly at 24 months on the four scales. CONCLUSIONS: A post hoc examination of subjects with SCL-90 scores above general population means, showed less improvement in the Information group than the two therapy groups combined (P < 0.05).     

Effects of mailed advice on stress reduction among employees in Japan: a randomized controlled trial.

We conducted a randomized controlled trial (RCT) to examine the effects of mailed advice on reducing psychological distress, blood pressure, serum lipids, and sick leave of workers employed in a manufacturing plant in Japan. Those who indicated higher psychological distress (defined as having GHQ scores of three or greater) in the baseline questionnaire survey (n = 226) were randomly assigned to an intervention group or a control group. Individualized letters were sent to the subjects of the intervention group, informing them of their stress levels and recommending an improvement in daily habits and other behaviors to reduce stress. Eighty-one and 77 subjects in the intervention and control groups, respectively, responded to the one-year follow-up survey. No significant intervention effect was observed for the GHQ scores, blood pressure, serum lipids, or sick leave (p > 0.05). The intervention effect was marginally significant for changes in regular breakfasts and daily alcohol consumption (p = 0.09). The intervention effect was marginally significant for the GHQ scores among those who initially did not eat breakfast regularly (p = 0.06). The study suggests that only sending mailed advice is not an effective measure for worksite stress reduction. Mailed advice which focuses on a particular subgroup (e.g., those who do not eat breakfast regularly) may be more effective.     

Changing health behaviour outcomes in asthmatic patients: a pilot intervention study

Starting from a prior study, in which cognitive and coping variables proved to be related to well-being, the use of medical resources and the absence from work in asthmatic patients, the authors constructed a cognitive-educational (a combination of health education and rational emotive behaviour modification) intervention programme aiming at altering coping behaviour in asthmatic patients in order to influence emotional distress and use of medical resources. The effects of the programme were assessed by means of a pre-test-post-test control group design. The programme was offered to ten patients and their partners. Both before and after the intervention cognitive attitudes (optimism, locus of control, and shame or stigma), coping behaviour in attack situations (minimizing the seriousness of the attack, rational action and reacting emotionally), coping in daily life (maintaining a restrictive life-style, focussing on asthma and hiding asthma), emotional distress (anxiety, anger, and depression), and the use of medication were measured in the experimental and control group. It was found that patients who received the programme became less preoccupied with their asthma and reported significantly less emotional distress (anxiety and anger) in daily life. In addition, they used less maintenance medication (corticosteroids). The authors wish to stress the importance of using medical variables such as the number of attacks as covariates in this type of research.     

Reductions in stress and depressive symptoms in mothers of substance-exposed infants, participating in a psychosocial program

OBJECTIVE: Depression profoundly impairs psychosocial functioning. Depression can have disruptive effects on a person's family, with significant impact on the psychosocial development of the children. Recent research suggests that a mother's depressive symptoms may increase parenting stress and that parenting stress may, in turn, increase depressive symptoms, with a possible negative cycle to this process. Little is known about how these two factors interact in drug-involved mothers. This study examines how the NEW CONNECTIONS intervention (a parental education and support program for drug-involved parents) acts on parental stress and symptoms of depression. METHODS: The study site was the NEW CONNECTIONS Infant Intervention Program. The Beck Depression Inventory-II (BDI-II) and the Parenting Stress Index (PSI) were administered to drug- and alcohol-involved mothers (N = 120) at baseline and after the intervention (Week 12). RESULTS: Four of the seven PSI domains of parenting stress showed a significant reduction (Demandingness, Competence, Isolation, and Role Restriction). Changes in four domains were significantly correlated with reductions in depressive symptoms (Competence, Isolation, Attachment, and Role Restriction). There was a significant reduction in depressive symptoms as measured by the BDI-II. CONCLUSION: Reduction in some aspects of parenting stress is associated with reduction in depressive symptoms in mothers of substance-exposed infants who participated in the NEW CONNECTIONS psychosocial intervention targeting the parent-child relationship.     

Effects of a brief worksite stress management program on coping skills, psychological distress and physical complaints: a controlled trial

Objectives: To examine the effects of single-session, small-group stress management program on knowledge about stress, coping skills, and psychological and physical distress. Methods: A total of 300 employees from a company in western Japan were invited to participate in the study. Those who consented to enter the study were assigned to an intervention (n=149) or waiting list control group (n=151). Participants in the intervention group received a small-group stress management program. The program was primarily aimed at increasing knowledge about stress and improving coping skills. To investigate the intervention effect, change scores in outcome variables were calculated by subtracting the scores at pre-intervention from those at post-intervention (8 weeks after the pre-intervention survey). Next, the difference in the scores between groups was examined using analyses of covariance (ANCOVA) with the pre-intervention score as the covariate. Results: Favorable intervention effects were found on knowledge about stress and on coping skills (P<0.001 and P=0.012, respectively) and adverse effects on psychological distress (P=0.022). However, this adverse effect on psychological distress did not exist among those who initially perceived higher levels of job control. Conclusion: The single-session stress management program was effective on improving knowledge about stress, and coping skills, where job control moderated the effect of the program on psychological distress.

A Stress Reduction Program Led by Health Care Personnel: Effects on Health and Well-Being

The aim of the study was to evaluate a stress control programwhich can be led by nurses. The program consisted of 10 threehour sessions conducted weekly. The meetings were devoted totheoretical lectures, discussions about personal stress experiences,and relaxation training. Participants read written materialand practiced relaxation between sessions. Subjects in an interventiongroup showed significant changes in the following variables:fewer perceived daily hassles; more positive self-esteem; improvedproblem-focused coping capacity; improved eating and exercisehabits; fewer self-reported psychological symptoms; improvedsubjective health status and well-being; lowered level of diastolicblood pressure; reduced waist-hip ratio; and an increase inactions taken against stressors. The results were discussedas promising but it was noted that the program seemed to attracta select group; women with academic training.     

The impact of depressive symptomatology on physical disability: MacArthur Studies of Successful Aging.

OBJECTIVES. The purpose of these analyses was to test the hypothesis that depressive symptomatology affects the risk of onset of physical disability in high-functioning elderly adults. METHODS. The data come from the MacArthur Study of Successful Aging, a community-based cohort of high-functioning adults aged 70 through 79 years who were assessed twice at a 2.5-year interval. Physical and cognitive status was assessed by performance as well as by self-report measures. RESULTS. In gender-stratified logistic regression models, high depressive symptoms as measured by the depression subscale of the Hopkins Symptom Checklist were associated with an increased risk of onset of disability in activities of daily living for both men and women, adjusting for baseline sociodemographic factors, physical health status, and cognitive functioning. CONCLUSIONS. Joined with evidence that physical disability is a potential risk factor for depression, these findings suggest that both depressive symptoms and physical disability can initiate a spiralling decline in physical and psychological health. Given the important impact of activities-of-daily-living functioning on utilization of medical services and quality of life, prevention or reduction of depressive symptoms should be considered an important point of intervention.     

A randomised controlled trial of the effects of mindfulness practice on medical student stress levels

Medical Education 2011: 45 : 381–388 Objective This study aimed to determine whether the practice of mindfulness reduces the level of stress experienced by senior medical students. Methods We carried out a multicentre, single‐blinded, randomised controlled trial with intention‐to‐treat analysis in three clinical schools attached to the University of Tasmania, Hobart, Tasmania. Participants included 66 medical students in their final 2 years of study in 2009. Participants were block‐randomised to either an intervention or a usual care control group. The intervention used an audio CD of guided mindfulness practice designed and produced for this trial. Participants were advised to use the intervention daily over the 8 weeks of the trial. All participants completed two self‐report questionnaires, at baseline and at 8 weeks, respectively. The intervention group also completed a questionnaire at 16 weeks to provide follow‐up data. The primary outcome measure was the difference over time in scores on the Perceived Stress Scale (PSS). The secondary outcome measure referred to differences over time in scores on the subscales of the Depression, Anxiety and Stress Scale (DASS). Results Mean baseline scores on the PSS and the stress component of the DASS were 15.7 (maximal score of 40) and 13.2 (maximal score of 42), respectively, both of which exceed scores in age‐matched normative control data. Using multivariable analysis, participants in the intervention group demonstrated significant reductions in scores on the PSS (? 3.44, 95% confidence interval [CI] ? 6.20 to ? 0.68; p < 0.05) and the anxiety component of the DASS (? 2.82, 95% CI ? 4.99 to ? 0.64; p < 0.05). A borderline significant effect was demonstrated on the stress component of the DASS (? 3.69, 95% CI ? 7.38 to 0.01; p = 0.05). Follow‐up at 8 weeks post‐trial revealed that the effect was maintained. Conclusions Mindfulness practice reduced stress and anxiety in senior medical students. Stress is prevalent in medical students and can have adverse effects on both student health and patients. A simple, self‐administered, evidence‐based intervention now exists to manage stress in this at‐risk population and should be widely utilised.

Weight-control intervention in overweight subjects at high risk of cardiovascular disease: a trial of a public health practical training program in a medical school

OBJECTIVE: To evaluate the effectiveness of a weight-control intervention for overweight subjects at high risk of cardiovascular disease (CVD) at a worksite conducted by medical students as a public health practical training program. METHODS: A total of 45 men and women who were obese (BMI > or = 24.0 kg/m2) and found to be hypertensive (SBP > or = 140 mmHg or DBP > or = 90 mmHg) or suffering from hypercholesterolemia (total serum cholesterol > or = 220 mg/dl) in an annual health check up in November 2001 were invited to participate in a weight-control intervention program. Eight individuals agreed (intervention group) and other sixteen control subjects whose sex and age (+/- 3 years) were matched to the intervention subjects were selected. The duration of the program was three months (from July to October 2002) and a 2 kg weight reduction in that period was set as the goal. The baseline survey consisted of a dietary questionnaire and a health quiz. Subjects had two counseling sessions and received four personal letters in the three months. A semi-quantitative food frequent questionnaire, a photograph method (Diet Agent Service, Matsushita Electric Works, Ltd.) and three day food records were conducted for dietary surveys. Changes in bodyweight, BMI, blood pressure, and serum total cholesterol concentration from November 2001 to November 2002 were compared between the intervention and control groups. Food group intakes and nutrient intakes were compared between weight reduction achievers and non-achievers. RESULTS: Mean bodyweight changes from November 2001 to November 2002 were -2.3 kg (SD 3.3 kg) for the intervention group and +0.3 kg (SD 1.5 kg) for the control group, the difference being significant (p = 0.013). For the intervention group mean bodyweight change from July to October 2002 was -1.5 kg (SD 2.4 kg). For total serum cholesterol, the mean changes were -32.1 mg/dl vs. +0.5 mg/dl (p = 0.005), for SBP -9.5 mmHg vs. +4.7 mmHg (p = 0.083) and for DBP -2.8 mmHg vs. +1.4 mmHg (p = 0.438). These were thought to be consequences of weight-control intervention. From dietary surveys, weight reduction achievers increased fish intake and decreased fats, snacks and sweets. Those who answered the health quiz more correctly demonstrated more reduction of bodyweight. CONCLUSIONS: Effectiveness of a weight-control intervention for reduction of CVD risk factors was found in the present public health practical training program for medical students. Dietary advice based on various dietary surveys was indicated to be effective in the weight-control program. A population strategy to distribute health information appeared necessary for effective health education programs for high-risk subjects.     

Assessment of psychotropic-like properties of a probiotic formulation (Lactobacillus helveticus R0052 and Bifidobacterium longum R0175) in rats and human subjects

In a previous clinical study, a probiotic formulation (PF) consisting of Lactobacillus helveticus R0052 and Bifidobacterium longum R0175 (PF) decreased stress-induced gastrointestinal discomfort. Emerging evidence of a role for gut microbiota on central nervous system functions therefore suggests that oral intake of probiotics may have beneficial consequences on mood and psychological distress. The aim of the present study was to investigate the anxiolytic-like activity of PF in rats, and its possible effects on anxiety, depression, stress and coping strategies in healthy human volunteers. In the preclinical study, rats were daily administered PF for 2 weeks and subsequently tested in the conditioned defensive burying test, a screening model for anti-anxiety agents. In the clinical trial, volunteers participated in a double-blind, placebo-controlled, randomised parallel group study with PF administered for 30?d and assessed with the Hopkins Symptom Checklist (HSCL-90), the Hospital Anxiety and Depression Scale (HADS), the Perceived Stress Scale, the Coping Checklist (CCL) and 24?h urinary free cortisol (UFC). Daily subchronic administration of PF significantly reduced anxiety-like behaviour in rats (P?相似文献   

The effect of a weight reduction program on cardiovascular risk factors among overweight hypertensives in primary health care

The aim of the study was to test the effect of a nonpharmacological weight reduction program on cardiovascular risk factors among overweight hypertensives in a primary health care setting. Forty-nine overweight hypertensive patients completed the 12-month program. The patients were randomly allocated into either intervention or control groups. The examinations included interviews by a nutritionist, pertinent laboratory tests, and a medical examination. The intervention involved an individually planned energy-restricted diet of 1000-1500 kcal per day, weekly discussions, and various leaflets on diet modification and on increase of physical activity. The mean body weight was reduced by 5 kg in the intervention group, but remained unchanged in the control group. The intervention group reduced their fat intake by 14 g/day while the control group increased it by 9 g/day on the average. In the intervention group, the total serum cholesterol decreased, HDL-cholesterol increased and triglycerides decreased significantly. The systolic blood pressure fell by 8 mm Hg and 15 mm Hg in the intervention and control groups, respectively. The diastolic blood pressure fell on average by 11 mm Hg in both groups. The results demonstrate the comprehensive weight reduction program to be effective in the control of cardiovascular risk factors.     

Evaluating the impact of a disease management program for chronic complex conditions at two large northeast health plans using a control group methodology.

The objective of this study was to observe trends in payer expenditures for plan members with one of 14 chronic, complex conditions comparing one group with a disease management program specific to their condition (the intervention group) and the other with no specific disease management program (the control group) for these conditions. The authors used payer claims and membership data to identify members eligible for the program in a 12-month baseline year (October 2001 to September 2002) and a subsequent 12-month program year (October 2002 to September 2003). Two payers were analyzed: one health plan with members primarily in New Jersey (AmeriHealth New Jersey [AHNJ]), where the disease management program was offered, and one affiliated large plan with members primarily in the metro Philadelphia area, where the program was not offered. The claims payment policy for both plans is identical. Intervention and control groups were analyzed for equivalence. The analysis was conducted in both groups over identical time periods. The intervention group showed statistically significant (p < 0.01) differences in total paid claims trend and expenditures when compared to the control group. Intervention group members showed a reduction in expenditures of -8%, while control group members showed an increase of +10% over identical time periods. Subsequent analyses controlling for outliers and product lines served to confirm the overall results. The disease management program is likely responsible for the observed difference between the intervention and control group results. A well-designed, targeted disease management program offered by a motivated, supportive health plan can play an important role in cost improvement strategies for members with complex, chronic conditions.     

Effects of an educational programme on adolescents with premenstrual syndrome

An education program was developed and evaluated to determine its efficacy in increasing knowledge and decreasing the severity of symptoms of premenstrual syndrome (PMS). Participants from a sample of 94 schoolgirls aged between 14 and 18 years from four secondary schools in Hong Kong were assigned to either the experimental or control group. Immediately following the education program, the schoolgirls in the experimental group had significantly increased knowledge scores as measured by the Premenstrual Syndrome Knowledge Questionnaire. Three months following the education program, schoolgirls in the experimental group reported having a significant reduction in total PMS scores and three of the subscale scores as measured by a translated version of Abraham's Menstrual Symptom Questionnaire. In addition, no significant differences were found for the control group on pre-test and post-test PMS scores suggesting that the education program could have been the source of the reduction in PMS symptoms of the experimental group of young adolescents girls.
