Ten-year trends in health-related quality of life after surgical and conventional treatment for severe obesity: the SOS intervention study

Objective:To examine trends and effects of weight loss treatment on health-related quality of life (HRQL) in the severely obese over 10 years.Design:Swedish obese subjects (SOS) intervention study is a controlled, longitudinal trial of the health effects of weight loss in the severely obese.Subjects:A total of 655 of 851 surgically treated and 621 of 852 conventionally treated obese men (body mass index, BMI⩾34) and women (BMI⩾38) who completed 10 years of the study.Measurements:HRQL was assessed before treatment and after 0.5, 1, 2, 3, 4, 6, 8 and 10 years.Results:HRQL change during the 10-year observation period largely followed phases of weight loss, weight regain and weight stability. Improvements and deteriorations in HRQL were associated with the magnitude of weight loss or regain, except regarding anxiety. Peak improvements in the surgical group were observed during the first year of weight loss, whereas the weight regain phase (mainly between 1- and 6-year follow-up) was accompanied by a gradual decline in HRQL. The period from 6- to 10-year follow-up was characterized by relatively stable observations in both weight and HRQL. At 10 years, net gains were noted in all HRQL domains compared to baseline. Comparisons of treatment effects on HRQL in the surgical vs conventional group after 10 years showed significantly better outcome in the surgical group on current health perceptions, social interaction, psychosocial functioning and depression, whereas no significant differences were found for overall mood and anxiety. Long-term results of the study suggest that a maintained weight loss of about 10% is sufficient for positive long-term effects on HRQL, a limit that was reached in about two-thirds of the surgically treated patients who completed 10 years of the study.Conclusion:Long-lasting weight reduction in the severely obese has a general long-standing positive outcome on HRQL. Bariatric surgery is a favorable option for the treatment of severe obesity, resulting in long-term weight loss and HRQL improvements in a majority of patients. However, difficulties among some surgical patients to control and maintain weight loss over time should not be ignored. Future research should study if the long-term efficacy of bariatric surgery may be further enhanced by implementing lifestyle modification techniques in the postoperative management of patients.

Severe obesity and personality: a comparative controlled study of personality traits

OBJECTIVE: The primary purpose was to assess personality trait differences between the severely obese seeking treatment and a mainly non-obese reference group. We also investigated gender differences and differences between obese patients and obese not seeking treatment.METHOD: Personality traits were assessed using 7 of 15 scales from the Karolinska Scales of Personality (KSP): Somatic Anxiety, Muscular Tension, Psychastenia, Psychic Anxiety, Monotony Avoidance, Impulsiveness, and Irritability. Patients from the Swedish Obese Subjects (SOS) intervention study (n=3270, ages 37–57, 71% women) and the SOS reference study (n=1135, 54% women) completed the survey. Data presented in this study were gathered prior to treatment. Significance tests and effects sizes were calculated.RESULTS: Although statistically significant differences were found between obese patients and reference subjects on nearly all personality traits, effect sizes were at most moderate. Of the three scales with moderate effects sizes, differences on Somatic Anxiety and Psychastenia could be traced to items tapping condition-specific symptoms, e.g., problems with sweating and breathing as indicators of Somatic Anxiety. Moderate differences on the Impulsiveness scale (men alone) could not be explained by item composition. Further, the obese patients differed from obese in the reference group, and both obese and reference women reported significantly higher levels on Somatic Anxiety, Muscular Tension and Psychic Anxiety compared to men (effect size: small).CONCLUSIONS: Our results provided no evidence of a general obese personality profile, instead considerable heterogeneity in personality traits was observed across our obese samples (treatment seekers vs non-seekers, men vs women) and generally only small differences were noted compared to a reference study population. Further research is needed to investigate if the somewhat elevated levels of Impulsiveness, particularly among male obese patients, is affected by weight loss. When assessing personality traits in diseased groups consideration should be given to possible confounding from, e.g., somatic symptoms.

Relations between coping strategies and health-related quality of life in patients with spinal cord lesion

OBJECTIVE Although the use of appropriate coping strategies has been suggested to be a key factor in determining successful adjustment to severe physical illness/disability, little systematic support for this link has been found. We investigated relationships between spinal cord lesion-related coping strategies and health-related quality of life when studying for sociodemographic, disability-related and social support variables. DESIGN AND SUBJECTS We studied 256 persons with traumatically acquired spinal cord lesion (=1 year) from a typical rural/urban Swedish area in a cross-sectional design. METHODS Coping measure was the Spinal Cord Lesion-related Coping Strategies Questionnaire. Outcome measures were the Spinal Cord Injury Quality of Life Questionnaire, the Short-Form 36 Health Survey version 2.0, and a standardized global question of overall quality of life. Multiple regressions were performed. RESULTS Coping strategies were clear correlates of health-related quality of life when sociodemographic, disability-related and social support variables were studied. The relationship between coping strategies and quality of life was: the more revaluation of life values (Acceptance) and the fewer tendencies towards dependent behaviour (Social reliance) the better the health-related quality of life. CONCLUSION Our results suggest that greater focus needs to be directed to coping strategies and to ways of facilitating adaptive outcomes in rehabilitation.

Linkages between coping and psychological outcome in the spinal cord lesioned: development of SCL-related measures.

Study design: Cross-sectional.Objectives: To investigate relationships between coping and mental well-being with clinical relevance to spinal cord lesion (SCL).Setting: The Gothenburg Spinal Injuries Unit in Sweden.Methods: The study sample comprised 274 persons. From in-depth interviews, literature reviews, and the transactional theory of stress and coping, items reflecting coping and psychological outcome, respectively were generated. Principal components factor analysis, multi-trait analysis, and structural equation modelling were used.Results: The coping scale comprised three factors: Acceptance (i.e. revaluation of life values); Fighting spirit (i.e. efforts to behave independently); Social reliance (i.e. a tendency towards dependent behaviour). The outcome scale included the factors: Helplessness (i.e. feeling perplexed, out of control and low self-esteem); Intrusion (i.e. bitterness and brooding); Personal growth (i.e. positive outcomes of life crisis). Acceptance showed a positive relation to Personal growth and was inversely related to both Helplessness and Intrusion. Fighting spirit had a weak negative association to Helplessness and a weak positive association to Personal growth. Social reliance was positively related to Helplessness and Intrusion. Only Social reliance showed any association to neurological status. Those lesioned 1–4 years reported more Helplessness, Intrusion, Social reliance, and less Acceptance than those lesioned ⩾5 years.Conclusion: Coping is related to psychological outcome in SCL. Our situational coping measure may be a candidate to assess intervention effects.

Effects of coping on psychological outcome when controlling for background variables: a study of traumatically spinal cord lesioned persons

Study design: Cross-sectional.Objectives: In a previous study we found spinal cord lesion (SCL)-related coping factors to be distinctly related to levels of SCL-related psychological outcome. However, we did not control for other potentially confounding variables. In this study we investigated effects of coping strategies on psychological outcome reactions in traumatically spinal cord lesioned persons controlling for sociodemographic, disability-related and social support variables.Setting: The Gothenburg Spinal Injuries Unit in Sweden.Methods: The study sample comprised 255 persons and a subsample of 157 persons. A series of stepwise multiple regression analyses were performed.Results: SCL-related coping factors clearly predicted psychological outcome even when background variables were controlled. Higher levels of acceptance coping predicted decreased psychological distress and increased positive morale. Elevated social reliance coping predicted heightened distress. Higher levels of social support predicted lower feelings of helplessness. Sociodemographic and disability-related variables were weak predictors of psychological outcome with one exception: higher education predicted less bitterness and brooding.Conclusion: SCL-related coping remained the most important predictor of psychological outcome even when a wide range of variables was controlled. Thus we conclude that psychosocial interventions aimed at helping individuals develop their coping strategies might be of substantial value in their adjustment to SCL.

A comparative controlled study of personality in severe obesity: a 2-y follow-up after intervention

OBJECTIVE: The primary purpose was to examine 2-y effects of weight change on personality traits in severely obese subjects treated conventionally or surgically. We also assessed differences between the severely obese patients and a primarily normal-weight reference group.METHOD: Personality traits were assessed using 7 of 15 scales from the Karolinska Scales of Personality (KSP): Somatic Anxiety, Muscular Tension, Psychasthenia, Psychic Anxiety, Monotony Avoidance, Impulsiveness, and Irritability. A total of 1380 surgical candidates, 1241 conventionally treated patients and 1135 subjects from the SOS (Swedish Obese Subjects) reference study, representing the general population, completed the KSP. Data presented in this study were gathered twice from the patients (prior to treatment and after 2 y) and once from the reference subjects. Significance tests and effect sizes (ES) were calculated.RESULTS: At baseline, the obese were characterised as more anxiety prone, impulsive, irritable and less monotony avoiding than the reference group; surgery patients more so than the conventionally treated. At follow-up, it was found that anxiety proneness decreased and Monotony Avoidance increased with increasing weight loss. The conventionally treated were, on average, weight stable and, hence, only a small decrease was noted regarding Somatic Anxiety. The surgery group lost on average 28 kg, and differences between surgically treated and the reference group decreased on all scales except Impulsiveness, which remained unchanged. The largest improvement was in relation to Psychasthenia.CONCLUSIONS: Weight reduction maintained for 2 y was associated with changes on practically all personality traits in proportion to the magnitude of weight loss. In particular, Psychasthenia seemed to be alleviated, while Impulsiveness was unaffected.

Self evaluation of communication experiences after laryngeal cancer – A longitudinal questionnaire study in patients with laryngeal cancer

BackgroundAim of this longitudinal study was to investigate the sensitivity to change of the Swedish Self Evaluation of Communication Experiences after Laryngeal Cancer questionnaire (the S-SECEL), addressing communication dysfunction in patients treated for laryngeal cancer. Previous studies have highlighted the need for more specific questionnaires for this purpose.Methods100 patients with Tis-T4 laryngeal cancer were included prior to treatment onset. Patients answered four questionnaires at six occasions during one year; the S-SECEL, the European Organisation for Research and Treatment of Cancer (EORTC) Core Quality of Life Core Questionnaire (QLQ-C30) supplemented by the Head and Neck cancer module (QLQ-H&N35) and the Hospital Anxiety and Depression (HAD) scale. In addition, performance status was assessed. Differences within groups were tested with the Wilcoxon paired signed ranks test and between-group analyses were carried out using the Mann-Whitney U test. Magnitude of group differences was analyzed by means of effect sizes.ResultsThe S-SECEL was well accepted with a response rate of 76%. Communication dysfunction increased at 1 month, followed by a continuous decrease throughout the year. Changes were statistically significant at most measurement, demonstrating the sensitivity of the S-SECEL to changes in communication over time. The S-SECEL and the EORTC QLQ-C30 with the QLQ-H&N35 demonstrated similar results; however the S-SECEL was more sensitive regarding communication dysfunction. The largest changes were found in the most diagnose specific items concerning voice and speech.ConclusionThe S-SECEL was investigated in the largest Scandinavian longitudinal study concerning health-related quality of life (HRQL) in laryngeal cancer patients. The questionnaire was responsive to change and showed convergent results when compared to established HRQL questionnaires. Our findings also indicate that the S-SECEL could be a more suitable instrument than the EORTC QLQ-C30 with QLQ-H&N35 when measuring communication experiences in patients with laryngeal cancer; it is more sensitive, shorter and can be used on an individual basis. As a routine screening instrument the S-SECEL could be a valuable tool for identifying patients at risk for psychosocial problems and to help plan rehabilitation. It is therefore recommended for clinical use in evaluation of communication dysfunction for all patients with laryngeal cancer irrespective of treatment.

Coping and Distress: What Happens After Intervention? A 2-year Follow-up From the Swedish Obese Subjects (sos) Study

Objective The study examined effects of weight change on coping and distress in severely obese subjects treated conventionally or undergoing weight reduction surgery. Methods We used the Obesity Coping (OC) scale measuring emotion-focused, maladaptive coping (Wishful Thinking) and problem-focused, adaptive coping (Social Trust and Fighting Spirit). We also used the Obesity Distress (OD) scale (Intrusion and Helplessness) and the Hospital Anxiety and Depression (HAD) scale. A total of 1146 surgical candidates and 1085 conventionally treated patients completed the OC and OD before treatment and after 24 months. Results Weight gainers reduced their use of both problem- and emotion-focused coping, thus leaving distress levels unchanged. All participants who lost weight decreased in emotion-focused coping and distress. Participants losing 20 kg or more also increased in problem-focused coping, resulting in even greater improvements regarding distress. Conclusions Two years after starting treatment, the pattern and magnitude of change in coping and distress was the same irrespective of type of treatment and was, instead, related to the amount of weight change (the more weight change the greater the changes in coping and distress). Increases in problem-focused coping required major weight reduction, whereas minor weight gain led to a decrease. Emotion-focused coping decreased irrespective of direction of weight change, suggesting a general intervention effect of receiving professional help and support. These results have implications concerning behavior-based interventions of obese patients.

Effects of total laryngectomy on olfactory function, health-related quality of life, and communication: a 3-year follow-up study

BackgroundAs total laryngectomy results in loss of airflow through the nose, one of the adverse effects for a majority of patients is the reduced or complete loss of olfactory function. However, with the introduction of a new method, the Nasal Airflow-Inducing Maneuver (NAIM), an important technique is available for laryngectomized patients to regain the ability to smell. The purpose of the present study was to assess changes in olfaction, health-related quality of life (HRQL) and communication 3 years after NAIM rehabilitation.Methods18 patients (15 men and 3 women; mean age, 71 years) who had undergone laryngectomy and NAIM rehabilitation were followed longitudinally for 3 years. For comparison an age and gender matched control group with laryngeal cancer treated with radical radiotherapy was included. Olfactory function was assessed using the Questionnaire on Odor, Taste and Appetite and the Scandinavian Odor Identification Test. HRQL was assessed by: 1) the European Organization for Research and Treatment for cancer quality of life questionnaires; and 2) the Hospital Anxiety and Depression Scale. Communication was assessed by the Swedish Self-Evaluation of Communication Experiences after Laryngeal Cancer. Descriptive statistics with 95% confidence interval were calculated according to standard procedure. Changes over time as well as tests between pairs of study patients and control patients were analyzed with the Fisher nonparametric permutation test for matched pairs.ResultsThirty-six months after rehabilitation 14 of 18 laryngectomized patients (78%) were smellers. There were, with one exception (sleep disturbances), no clinically or statistically significant differences between the study and the control group considering HRQL and mental distress. However, statistical differences (p < 0.001) were found between the study and the control group concerning changes in communication.ConclusionOlfactory training with NAIM should be integrated into the multidisciplinary rehabilitation program after total laryngectomy. Our study shows that patients who were successfully rehabilitated concerning olfaction and communication had an overall good HRQL and no mental distress. Moreover, the EORTC questionnaires should be complemented with more specific questionnaires when evaluating olfaction and communication in laryngectomized patients.

Life values in patients with COPD: relations with pulmonary functioning and health related quality of life.

Theories of coping and response shift have suggested that emotional adaptation is related to value changes, e.g. a deemphasized importance of lost life values and an enlargement of the scope of values. Perceived attainment and importance of 82 life values were examined in 65 patients with chronic obstructive pulmonary disease (COPD) and related to clinical and Health-Related Quality of Life (HRQL) measures. The life values covered 10 dimensions – harmony, positive relations, involvement, mobility, communication, knowledge, responsibility, comfort, religion and health. Forty-six of the patients were followed up after 1 year. The patients with COPD were compared with a healthy control group, a group of neurologically impaired and a non-disabled group representing the general population. Significant congruence was found between importance and attainment ratings in all groups (correlations from 0.44 to 0.53), suggesting that both impaired and healthy persons tend to perceive that they have what they find important in life. Congruence was significantly related to mood (correlations from 0.28 to 0.40), but not to functional status or clinical data. Compared to the healthy responders, the patients with COPD had significantly lower attainment ratings in health, mobility, involvement, but no differences were found for importance ratings. No evidence was found that they had replaced unattainable values with new available values, and no changes over time of perceived values were found. This suggests that patients with COPD do not seem to adapt by means of changing their value orientation.
