Quality of life in youth with Tourette's syndrome and chronic tic disorder.

This study sought to examine quality of life (QoL) in clinic-referred children and adolescents (n = 59, M age = 11.4±2.6 years) with a chronic tic disorder. The QoL scores for tic patients were lower than for healthy controls but higher than for the psychiatric sample on the majority of domains. Childrens self-reported QoL scores and a measure of tic severity were moderately and inversely correlated. Parent reports of their childs QoL were weakly related to tic severity. Correlations between parent and child ratings of QoL for children ages 8 to 11 years were generally higher than those for youth ages 12 to 17 years. Finally, externalizing behavior moderated the relations between tic severity and parent-rated QoL, such that tic severity was significantly associated with parent-rated QoL for children with below average externalizing symptoms but not for children 3with above average externalizing symptoms.

Insight in pediatric obsessive-compulsive disorder: Associations with clinical presentation

Insight has emerged as a significant treatment outcome predictor in adult obsessive-compulsive disorder (OCD), with some suggesting that OCD with poor insight represents a distinct clinical subtype. Despite its clinical relevance, limited data exist on insight in pediatric OCD patients. The present study investigated the relation between poor insight and clinical characteristics among children and adolescents with OCD (N=78, ages 6-20 years). Forty-five percent of the sample (n=35) was considered to have low levels of insight into their symptoms, as determined by clinician rating on item 11 of the Childrens Yale-Brown Obsessive-Compulsive Scale. Pearson product-moment correlations showed a significant, inverse relation between insight and OCD severity. Relative to the high insight group, parents of patients with low insight reported higher levels of OCD-related impairment and family accommodation. These findings suggest that OCD with poor insight may represent a distinct clinical feature that may require more intensive and multimodal treatment approaches.

Effects of a weight loss plus exercise program on physical function in overweight, older women: a randomized controlled trial

Background: Obesity and a sedentary lifestyle are associated with physical impairments and biologic changes in older adults. Weight loss combined with exercise may reduce inflammation and improve physical functioning in overweight, sedentary, older adults. This study tested whether a weight loss program combined with moderate exercise could improve physical function in obese, older adult women. Methods: Participants (N = 34) were generally healthy, obese, older adult women (age range 55–79 years) with mild to moderate physical impairments (ie, functional limitations). Participants were randomly assigned to one of two groups for 24 weeks: (i) weight loss plus exercise (WL+E; n = 17; mean age = 63.7 years [4.5]) or (ii) educational control (n = 17; mean age = 63.7 [6.7]). In the WL+E group, participants attended a group-based weight management session plus three supervised exercise sessions within their community each week. During exercise sessions, participants engaged in brisk walking and lower-body resistance training of moderate intensity. Participants in the educational control group attended monthly health education lectures on topics relevant to older adults. Outcomes were: (i) body weight, (ii) walking speed (assessed by 400-meter walk test), (iii) the Short Physical Performance Battery (SPPB), and (iv) knee extension isokinetic strength. Results: Participants randomized to the WL+E group lost significantly more weight than participants in the educational control group (5.95 [0.992] vs 0.23 [0.99] kg; P < 0.01). Additionally, the walking speed of participants in the WL+E group significantly increased compared with that of the control group (reduction in time on the 400-meter walk test = 44 seconds; P < 0.05). Scores on the SPPB improved in both the intervention and educational control groups from pre- to post-test (P < 0.05), with significant differences between groups (P = 0.02). Knee extension strength was maintained in both groups. Conclusion: Our findings suggest that a lifestyle-based weight loss program consisting of moderate caloric restriction plus moderate exercise can produce significant weight loss and improve physical function while maintaining muscle strength in obese, older adult women with mild to moderate physical impairments.

Problem Solving, Treatment Adherence, and Weight-Loss Outcome Among Women Participating in Lifestyle Treatment for Obesity

OBJECTIVE This study examined whether improvements in problem-solving abilities mediate the relation between treatment adherence and weight-loss outcome in the behavioral treatment of obesity. METHOD 272 women (mean+/-SD age=59.4+/-6.2 years, BMI=36.5+/-4.8) participated in a 6-month lifestyle intervention for obesity. Body weight and problem-solving skills (as measured by the Social Problem Solving Inventory-Revised) were assessed pre- and posttreatment. The completion of self-monitoring logs during the intervention served as the marker of treatment adherence. RESULTS At posttreatment, participants lost 8.4+/-5.8 kg, an 8.8% reduction in body weight. Changes in weight were associated with increased problem-solving skills and with higher levels of treatment adherence. Improvements in problem-solving skills partially mediated the relation between treatment adherence and weight-loss outcome. Moreover, participants with weight reductions > or = 10% demonstrated significantly greater improvements in problem-solving skills than those with reductions <5%. DISCUSSION Improvements in problem-solving skills may enable participants to overcome barriers to adherence and thereby enhance treatment-induced weight losses.

The contributions of weight loss and increased physical fitness to improvements in health-related quality of life.

The relative contribution of obesity versus poor fitness to adverse health outcomes and diminished quality of life remains an area of controversy. Indeed, some researchers contend that poor cardiorespiratory fitness represents a greater threat to health and health-related quality of life than excess body weight. We addressed this issue by providing 298 obese 50-75 year-old women with a six-month lifestyle intervention that incorporated a low-calorie eating pattern coupled with an aerobic exercise program consisting of 30 min/day of brisk walking. The results showed that weight loss exhibited a significant individual contribution to improvements in seven of the nine domains of quality of life assessed by the Medical Outcomes Study Short Form (SF-36). With the exception of physical functioning, however, physical fitness did not significantly contribute to improvements beyond the effects weight loss. Moreover, weight loss functioned as a full mediator of the association between increases in physical fitness and improvements in general health, vitality, and change in health relative to the previous year. Collectively, these findings suggest that for treatment-seeking obese individuals, weight loss rather than increased fitness contributes significantly to improvements in health-related quality of life.

Successful long-term weight loss maintenance in a rural population

Background Few investigations of successful long-term weight loss beyond two years have been conducted, and none has examined weight changes in medically underserved rural populations of older adults. The purpose of this study was to assess long-term weight loss maintenance 3.5 years after the completion of an initial six-month lifestyle intervention for obesity among women aged 50–75 years residing in rural communities. Methods One hundred and ten obese women with a mean (± standard deviation) age of 60.08 ± 6.17 years and mean body mass index of 36.76 ± 5.10 kg/m2 completed an in-person assessment during which their weight and adherence to behavioral weight management strategies were evaluated. Results Participants showed a mean weight reduction of 10.17% ± 5.0% during the initial six- month intervention and regained 6.95% ± 9.44% from the completion of treatment to follow-up assessment 3.5 years later. A substantial proportion of participants (41.80%) were able to maintain weight reductions of 5% or greater from baseline to follow-up. “Successful” participants (those who maintained losses of 5% or greater at follow-up) reported weighing themselves, self-monitoring their intake and calories, planning meals in advance, and choosing lower calorie foods with greater frequency than “unsuccessful” participants (those who lost less than 5%). Conclusion Collectively, these findings indicate that a large proportion of participants were able to maintain clinically significant weight losses for multiple years after treatment, and that self-monitoring was a key component of successful long-term weight management.

Somatic Symptoms in Children and Adolescents with Obsessive-Compulsive Disorder: Associations with Clinical Characteristics and Cognitive-Behavioral Therapy Response

Despite being a core characteristic of anxiety disorders, little data have been reported on somatic symptoms (SSs) in youth with obsessive-compulsive disorder (OCD). Eighty-five children and adolescents with OCD were administered the Childrens Yale Brown Obsessive-Compulsive Scale and completed the Childrens Depression Inventory and Multidimensional Anxiety Scale for Children. Their parents completed the Child Behavior Checklist and Childrens Obsessive-Compulsive Impact Scale. A subset of youth (n = 62) completed a trial of cognitive-behavioral therapy. The frequency of specific SSs was examined in relation to age, gender, OCD symptom severity, child-rated symptoms of depression and anxiety, parent-proxy ratings of internalizing and externalizing problems, and functional impairment. Ninety-six percent of youth experienced at least one SS, with 67% reporting five or more SSs. Child-rated SSs were positively associated with parent-ratings of child SSs, child-rated anxiety and depression, and parent ratings of the childrens internalizing problems. Parent-rated SSs were positively related to parent-proxy ratings of internalizing problems and OCD-related impairment, clinician-rated OCD symptom severity, and child-rated generalized anxiety. Total and several specific SSs were reduced following cognitive-behavioral treatment. These results suggest that SSs are prevalent in youth with OCD, are associated with symptom severity, are reduced after participation in cognitive-behavioral therapy, and warrant attention during assessment and treatment.

Benefits and risks of weight-loss treatment for older, obese women

Background A key issue in the treatment of obesity in older adults is whether the health benefits of weight loss outweigh the potential risks with respect to musculoskeletal injury. Objective To compare change in weight, improvements in metabolic risk factors, and reported musculoskeletal adverse events in middle-aged (50–59 years) and older (65–74 years), obese women. Materials and methods Participants completed an initial 6-month lifestyle intervention for weight loss, comprised of weekly group sessions, followed by 12 months of extended care with biweekly contacts. Weight and fasting blood samples were assessed at baseline, month 6, and month 18; data regarding adverse events were collected throughout the duration of the study. Results Both middle-aged (n = 162) and older (n = 56) women achieved significant weight reductions from baseline to month 6 (10.1 ± 0.68 kg and 9.3 ± 0.76 kg, respectively) and maintained a large proportion of their losses at month 18 (7.6 ± 0.87 kg and 7.6 ± 1.3 kg, respectively); there were no significant differences between the two groups with respect to weight change. Older women further experienced significant reductions in systolic blood pressure, HbA1c, and C-reactive protein from baseline to month 6 and maintained these improvements at month 18. Despite potential safety concerns, we found that older women were no more likely to experience musculoskeletal adverse events during the intervention as compared with their middle-aged counterparts. Conclusion These results suggest that older, obese women can experience significant health benefits from lifestyle treatment for obesity, including weight loss and improvements in disease risk factors. Further investigation of the impact of weight loss on additional health-related parameters and risks (eg, body composition, muscular strength, physical functioning, and injuries) in older adults is needed.
