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.

Person-Centered Care — Ready for Prime Time

Long-term diseases are today the leading cause of mortality worldwide and are estimated to be the leading cause of disability by 2020. Person-centered care (PCC) has been shown to advance concordance between care provider and patient on treatment plans, improve health outcomes and increase patient satisfaction. Yet, despite these and other documented benefits, there are a variety of significant challenges to putting PCC into clinical practice. Although care providers today broadly acknowledge PCC to be an important part of care, in our experience we must establish routines that initiate, integrate, and safeguard PCC in daily clinical practice to ensure that PCC is systematically and consistently practiced, i.e. not just when we feel we have time for it. In this paper, we propose a few simple routines to facilitate and safeguard the transition to PCC. We believe that if conscientiously and systematically applied, they will help to make PCC the focus and mainstay of care in long-term illness.

Psychosocial functioning in the obese before and after weight reduction: construct validity and responsiveness of the Obesity-related Problems scale.

OBJECTIVE: The Obesity-related Problems scale (OP) is a self-assessment module developed to measure the impacts of obesity on psychosocial functioning. Our principal aim was to evaluate the construct validity and responsiveness of the OP scale. Our specific aims were to test: (1) the psychometric performance of OP; (2) if OP scores differed by gender and weight category; (3) if OP scores are inversely related to mental well-being; (4) if weight reduction in the obese is accompanied by improvements in psychosocial functioning (OP).SUBJECTS: Four samples were used: 6863 subjects in the SOS cross-sectional study; 2128 in the SOS intervention study; 1017 nonobese in the SOS reference study; and 3305 obese subjects in the XENDOS study.MEASUREMENTS: Psychosocial functioning was measured by OP. Overall mood was measured by MACL. Anxiety and depression symptoms were measured by HAD.RESULTS: Psychometric testing provided strong support for the construct validity of OP. Factor analysis confirmed the homogeneity of the construct and multitrait/multi-item scaling analysis demonstrated strong item-convergent/discriminant validity. Reliability coefficients were high and floor and ceiling effects were small. Psychometric results were cross-validated and replicated in subgroups by gender, age and body mass index (BMI). As expected, large differences in OP were observed between obese and nonobese (P<0.0001). Obese women reported more weight-related psychosocial problems than obese men (P<0.0001). Psychosocial disturbances (OP) among the obese were significantly related to poor mood (MACL; P<0.0001) and anxiety and depression symptoms (HAD; P<0.0001). Change in OP over time was strongly correlated with weight loss (P<0.0001). A distinct dose–response effect between weight reduction and improvements in OP was demonstrated. Scores on psychosocial functioning (OP) and mental well-being (MACL, HAD) in nonobese (BMI<30) surgical patients at 4-y follow-up were equal to scores observed in nonobese reference subjects (NS).CONCLUSION: OP is a psychometrically valid obesity-specific measure suitable for evaluating HRQL effects of obesity interventions. The negative impact of obesity on psychosocial functioning is considerable and disturbances are connected with poor mental well-being. Weight reduction in the obese is followed by improvements in both psychosocial functioning and mental well-being.

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.

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.

Color meaning and context: Comparisons of semantic ratings of colors on samples and objects

This article reports the results of a study comparing semantic ratings of color samples (chips) with those of the same colors applied to a variety of familiar objects. Subjects rated a set of 13 color chips and 5 sets of objects, each appearing in the same 13 colors, against 5 bipolar, 7-step semantic differential scales. The scales consisted of beautiful-ugly, elegant-vulgar, loud-discreet, masculine-feminine, and warm-cold. Analyses performed on the data indicated that generally few significant differences existed between chip and object ratings for the same color; when such differences existed, the chip was always rated more beautiful, elegant, discreet, feminine, and warm than the object; and differences between chip and object ratings were confined primarily to a limited number of colors, objects, and semantic scales. The results of this study have implications for the use of color chips in color planning and for the generality of results of earlier color meaning research.

Women's sexual functioning and sex life after spinal cord injury

Study design:Cross-sectional, mail-back questionnaire study.Objectives:To describe womens experiences of sexual functioning and sex life after spinal cord injury (SCI).Setting:Sweden, Denmark, Norway, Finland, and Iceland.Methods:All community-living SCI women treated at spinal cord centres in Sweden, Denmark, Norway, Finland, and Iceland meeting inclusion criteria (n=963) were mailed the study-specific SCI Women Questionnaire. Out of the 532 respondents, 392 reported having had sex after injury and were thus included in the study. The included women had a mean age of 42 years (range 18–68) and a mean time since injury of 11 years (range 2–54).Results:The SCI women reported that the injury caused many changes in their sex life and affected many aspects of their sexuality negatively. Some changes were of a physical nature (for example, decreased, lost, or changed sensation; difficulties to achieve orgasm; bladder or bowel problems; and difficulties to move and position oneself) whereas other changes were of a psychological nature (for example, feeling unattractive or less attractive, having less self-confidence, and difficulties to meet or find a partner).Conclusion:Successful SCI rehabilitation requires a holistic approach, taking into account the patients physical, psychological, and interpersonal circumstances. Given that many women with SCI remain sexually active but often experience less satisfaction after injury, it is important that rehabilitation efforts address this aspect of the patients life. Our results elucidating strategies applied by women with SCI to compensate for loss of genital sensation and cope with physiological impairment during sexual activity may serve to help professionals in developing rehabilitation programmes for women with SCI.

Uncertainty in illness among patients with chronic heart failure is less in person-centred care than in usual care

Background: Many patients with chronic heart failure (CHF) experience uncertainty regarding the treatment and characteristics of their illness. Person-centred care (PCC) emphasizes patient involvement in care. We have previously shown that PCC improved outcomes such as length of hospital stay and activities of daily living in patients with CHF. The impact of PCC on self-reported uncertainty in illness among patients hospitalized for CHF is still unknown. Aim: To evaluate whether PCC is associated with less self-reported uncertainty in illness compared with usual care in patients hospitalized for worsening CHF. Methods: Using a controlled before-and-after design, eligible CHF patients were assigned to either a usual care group or a PCC intervention group. Patient-reported uncertainty in illness was assessed at hospital discharge with the Cardiovascular Population Scale (CPS). The CPS consists of two domains: 1) Ambiguity (about illness severity); and 2) Complexity (of treatment and system of care). Results: Two hundred and forty-eight patients were included in the study; 123 in the usual care group and 125 in the PCC intervention. The PCC group had better scores than the usual care group in the CPS domains complexity (M=15.2, SD=4.7 vs. M=16.8, SD=4.7; p=0.020) and ambiguity (M=27.8, SD=6.6 vs. M=29.8, SD=6.9; p=0.041). Conclusion: Patients with CHF were less uncertain in their illness after PCC, which may help to equip and empower patients to manage their illness. Together with earlier findings of shortened hospital stay and improved activities of daily living, this indicates that PCC should be a standard approach for hospital care of patients with worsening CHF.

Obesity‐related coping and distress and relationship to treatment preference

OBJECTIVES The primary purpose was to define obesity-related strategies for coping with psychological problems connected with obesity. We also wanted to identify obesity-related distress and explore the effect of coping on distress. Thirdly, we wanted to investigate differences in coping and distress related to choice of surgery or conventional treatment. DESIGN Cross-sectional data from patients in the Swedish Obese Subjects (SOS) intervention study. METHODS An obesity-related questionnaire concerning coping and distress was created and evaluated in 2510 patients from the SOS study, using multitrait, exploratory and confirmatory factor analysis procedures. RESULTS Three coping factors were defined. Social Trust and Fighting Spirit were problem-focused, whereas Wishful Thinking was emotion-focused. Surgical candidates displayed lower levels of problem-focused and higher levels of emotion-focused coping. We also identified two distress factors: Intrusion and Helplessness. Wishful Thinking was positively related to distress, and Social Trust and Fighting Spirit were inversely related, thus explaining the higher levels of distress reported by the surgical candidates. CONCLUSIONS In our sample, emotion-focused coping proved maladaptive and was associated with increased distress. Problem-focused coping, however, was adaptive and associated with reduced distress. These findings partly explain psychological morbidity and should be taken into consideration in the treatment of obese people.
