Relation of health-related quality of life to metabolic syndrome, obesity, depression and comorbid illnesses

Effects of tocotrienol-enriched oat supplementation on metabolic profile, nutritional status and health-related quality of life among patients with metabolic syndrome

Background: Tocotrienol has garnered significant attention due to its potent antioxidant and anti-inflammatory effects in ameliorating cardiovascular-related comorbidities. The present study aimed to elucidate the effects of tocotrienol-enriched oat supplementation on individuals with metabolic syndrome (MetS). Method: This was a randomized, double-blind, placebo-controlled human clinical trial. Patients with MetS were randomized to the tocotrienol-enriched oat (TO), oat (O) or control (C) groups. Both TO and O groups were supplemented twice daily for 12 weeks, while group C did not receive any intervention. Changes in the metabolic profile of individuals were considered as the primary endpoint. The secondary endpoints included the morphological assessment of nutritional and anthropometric parameters and health-related quality of life. Other measurements included compliance and tolerability to the study regime. Results: The rate of MetS remission in the TO and O groups was approximately twice than that in the control group (37.0% vs. 18.5%). After 12 weeks, the TO group showed significant improvements in the fasting blood glucose (-4.5%), blood pressure (systolic: -4.2%; diastolic: -5.3%), high density lipoprotein-cholesterol (HDL-C) (+34.1%), and triglyceride (-7.1%) (p < 0.05) levels. Group TO demonstrated an increase in muscle mass (+0.301 kg, p < 0.05) and reduced body fat (-0.775%, p < 0.05). Both the TO and O groups showed improvements in the overall HR-QoL, and the visual analogue scale (VAS) score. Conclusion: Twelve weeks of tocotrienol-enriched oat supplementation improved surrogate endpoints associated with MetS. This complementary dietary management approach may be more effective at alleviating MetS symptoms than the pharmacological approach alone and could be a safe dietary strategy for secondary prevention.

Metabolic syndrome

The metabolic syndrome (MetS) is a multiplex modifiable risk factor for cardiovascular disease, type 2 diabetes mellitus and other health outcomes, and is a major challenge to clinical practice and public health. The rising global prevalence of MetS, driven by urbanization, sedentary lifestyles and dietary changes, underlines the urgency of addressing this syndrome. We explore the complex underlying mechanisms, including genetic predisposition, insulin resistance, accumulation of dysfunctional adipose tissue and ectopic lipids in abdominal obesity, systemic inflammation and dyslipidaemia, and how they contribute to the clinical manifestations of MetS. Diagnostic approaches vary but commonly focus on abdominal obesity (assessed using waist circumference), hyperglycaemia, dyslipidaemia and hypertension, highlighting the need for population-specific and phenotype-specific diagnostic strategies. Management of MetS prioritizes lifestyle modifications, such as healthy dietary patterns, physical activity and management of excess visceral and ectopic adiposity, as foundational interventions. We also discuss emerging therapies, including new pharmacological treatments and surgical options, providing a forward-looking perspective on MetS research and care. This Primer aims to inform clinicians, researchers and policymakers about MetS complexities, advocating for a cohesive, patient-centred management and prevention strategy. Emphasizing the multifactorial nature of MetS, this Primer calls for integrated public health efforts, personalized care and innovative research to address this escalating health issue.

The effect of a lifestyle intervention program using a mobile application versus the effect of a program using a booklet for adults with metabolic syndrome: A three-arm randomized controlled trial

PURPOSE

The research aimed to examine the effect of a lifestyle intervention program using mobile application versus booklet for adults with metabolic syndrome in Hong Kong. The outcomes comprised body weight (primary outcome), exercise amount, improvement of cardiometabolic risk factors, cardiovascular endurance, perceived stress scale, and exercise self-efficacy.

DESIGN

A three-arm randomized controlled trial namely App group, Booklet group, and control group was adopted.

METHODS

Two hundred sixty-four adults with metabolic syndrome were recruited from community centers from 2019 to December 2021. Inclusion criteria are those adults with metabolic syndrome, able to use a smart phone. All participants received a 30-min health talk. App group additionally received a mobile application, while Booklet group received a booklet, and the control group received a placebo booklet. Data were collected at baseline, Weeks 4, 12, and 24. SPSS and generalized estimating equations (GEE) model were employed for data analysis.

FINDINGS

Attrition rates were minimal, ranged from 2.65% to 6.44%. Both app and booklet group showed significant improvement in outcomes (exercise amount, waist circumference) when compared to control group. However, statistically significant and superior results were observed in app group, including body weight, exercise amount, waist circumference, body mass index, and systolic blood pressure when compared to booklet group.

CONCLUSION

The lifestyle intervention supported with app was found to be superior to the booklet support for reducing body weight and maintaining exercise.

CLINICAL RELEVANCE

The lifestyle intervention program using mobile application support could be used widely for adults with metabolic syndrome in the community. Suggest nurses may incorporate this program in their health promotion strategies focusing on a healthy lifestyle to reduce the risk of progression to metabolic syndrome.

Mental health and quality of life in different obesity phenotypes: a systematic review

Objectives

It has been suggested that obesity phenotypes are related to mental health problems and health-related quality of life (HRQoL). However, there is no certain consensus. This systematic review aimed to evaluate the association between different obesity phenotypes with common psychiatric symptoms and HRQoL.

Methods

Electronic databases i.e. PubMed, Scopus, EMBASE, and google scholar were searched until September 2021, to identify studies that investigated associations between the obesity phenotypes with psychiatric symptoms and/or mental and physical HRQoL. Two researchers independently checked titles and abstracts, evaluated full-text studies, extracted data, and appraised their quality using the Newcastle–Ottawa Scale.

Results

Eighteen studies, with a total of 3,929,203 participants, were included. Of the studies included in this systematic review, 10 articles evaluated the association between obesity phenotypes and psychiatric symptoms, while six papers investigated the association between HRQoL and obesity phenotypes, and two studies assessed both. As a whole, the findings of these studies suggest that obese individuals with a favorable metabolic profile have a slightly higher risk of mental health problems and poor quality of life, however, the risk becomes larger when obesity is combined with an adverse metabolic profile. So, metabolically healthy obesity may not be a completely benign condition in relation to mental disorders and poor quality of life.

Conclusion

According to published research, obesity is likely to increase the risk of mental health problems and poor quality of life when metabolic disturbances are present.

Does the Presence of Metabolic Syndrome Alter Serum Uric Acid Concentrations, Pain, and Well-Being in Patient with Chronic Musculoskeletal Pain?

Objective: To compare serum uric acid concentrations, pain and well-being in patients having chronic musculoskeletal pain with and without MetS, and investigate cut-off values. Methods: Patients having chronic musculoskeletal pain with (MetS group, n=48) and without MetS (control group, n=52) were included. The serum uric acid concentration, pain intensity, body composition, physical activity level, quality of life, and psychological status were evaluated by a uric acid blood test, Visual Analogue Scale, Bio-impedance Analyzer, International Physical Activity Questionnaire-7 (IPAQ-7), Nottingham Health Profile, and Hospital Anxiety and Depression Scale, respectively. Results: Uric acid level, fat mass, waist/hip ratio were found higher in the MetS group in comparison to the control group (P

Cost-Effectiveness of Combination of Baricitinib and Remdesivir in Hospitalized Patients with COVID-19 in the United States: A Modelling Study

INTRODUCTION

Baricitinib-remdesivir (BARI-REM) combination is superior to remdesivir (REM) in reducing recovery time and accelerating clinical improvement among hospitalized patients with coronavirus disease 2019 (COVID-19), specifically those receiving high-flow oxygen/noninvasive ventilation. Here we assessed the cost-effectiveness of BARI-REM versus REM in hospitalized patients with COVID-19 in the USA.

METHODS

A three-state model was developed addressing costs and patient utility associated with COVID-19 hospitalization, immediate post hospital care, and subsequent lifetime medical care. Analysis was performed from the perspective of a payer and a hospital. Both perspectives evaluated two subgroups: all patients and patients who required oxygen. The primary measures of benefit in the model were patient quality-adjusted life years (QALYs) accrued during and after hospitalization, cost per life years gained, cost per death avoided, and cost per use of mechanical ventilation avoided.

RESULTS

In the base-case payer perspective with a lifetime horizon, treatment with BARI-REM versus REM resulted in an incremental total cost of $7962, a gain of 0.446 life years and gain of 0.3565 QALYs over REM. The incremental cost-effectiveness ratios of using BARI-REM were estimated as $22,334 per QALY and $17,858 per life year. The base-case and sensitivity analyses showed that the total incremental cost per QALY falls within the reduced willingness-to-pay threshold of $50,000/QALY applied under health emergencies. In all hospitalized patients, treatment with BARI-REM versus REM reduced total hospital expenditures per patient by $1778 and total reimbursement payments by $1526, resulting in a $252 reduction in net costs per patient; it also resulted in a net gain of 0.0018 QALYs and increased survival of COVID-19 hospitalizations by 2.7%.

CONCLUSION

Our study showed that BARI-REM is cost-effective compared to using REM for hospitalized patients with COVID-19. The base-case results of this cost-effectiveness model were most sensitive to average annual medical costs for recovered patients.

Investigation of quality of life in obese adolescents: the effect of psychiatric symptoms of obese adolescent and/or mother on quality of life

OBJECTIVES

The present study assessed the obese adolescents' health-related quality of life (HRQoL) based on both adolescent-reported and maternal-reported questionnaires to clarify adolescent-related psychiatric factors, maternal psychiatric factors, and body mass index (BMI) percentile variables that independently affect the quality of life (QoL).

METHODS

A total of 190 adolescents (120 females and 70 males) were included in the study. The impact of clinical and psychiatric factors on the Pediatric Quality of Life Inventory-Child Version (PedsQL-C) scores was analyzed using hierarchical linear regression methods.

RESULTS

The final models showed that only the Revised Child Anxiety and Depression Scale-Child Version major depressive disorder scores negatively predicted the physical, psychosocial, and total health scores of the PedsQL-C. The psychosocial scores of the PedsQL-P were negatively predicted by the Strengths and Difficulties Questionnaire emotional, and Conners' Parent Rating Scale-Revised-Short Form (CPRS-R-S) attention-deficit/hyperactivity disorder (ADHD) index scores. The PedsQL-P total scores were negatively predicted by the CPRS-R-S ADHD index scores.

CONCLUSIONS

The findings of this study indicate that the adolescents' psychiatric symptoms and BMI percentile played a significant role in the PedsQL subscale functioning of obese adolescents compared to maternal psychiatric symptoms.

Effects of Somatic, Depression Symptoms, and Sedentary Time on Sleep Quality in Middle-Aged Women with Risk Factors for Cardiovascular Disease

Cardiovascular disease (CVD) is the second leading cause of death among Korean women, and its incidence is dramatically elevated in middle-aged women. This study aimed to identify the predictors of sleep quality, a CVD risk factor, in middle-aged women with CVD risk factors to provide foundational data for developing intervention strategies for the prevention of CVD. The subjects, 203 middle-aged women (40–65 years old) with one or more CVD risk factors were selected through convenience sampling and included in this descriptive correlational study. The effects of somatic symptoms, depression symptoms, and sedentary time on sleep quality were examined. CVD-related characteristics were analyzed using descriptive statistics, whereas the mean values of the independent variables were analyzed using t-tests and analysis of variance. Predictors of sleep quality were analyzed using multiple regression analysis. The results showed that sleep quality increased with decreasing somatic symptoms (β = −0.36, p < 0.001), depression symptom score (β = −0.17, p = 0.023), and daily sedentary time (β = −0.13, p = 0.041), and the regression model was significant (F = 19.80, p < 0.001). Somatic symptoms are the most potent predictors of sleep quality in middle-aged women. Thus, intervention strategies that improve somatic symptoms are crucial for the enhancement of sleep quality, which deteriorates with advancing age.

Cost-Effectiveness of Baricitinib Compared With Standard of Care: A Modeling Study in Hospitalized Patients With COVID-19 in the United States

Purpose

In the Phase III COV-BARRIER (Efficacy and Safety of Baricitinib for the Treatment of Hospitalised Adults With COVID-19) trial, treatment with baricitinib, an oral selective Janus kinase 1/2 inhibitor, in addition to standard of care (SOC), was associated with significantly reduced mortality over 28 days in hospitalized patients with coronavirus disease–2019 (COVID-19), with a safety profile similar to that of SOC alone. This study assessed the cost-effectiveness of baricitinib + SOC versus SOC alone (which included systemic corticosteroids and remdesivir) in hospitalized patients with COVID-19 in the United States.

Methods

An economic model was developed to simulate inpatients' stay, discharge to postacute care, and recovery. Costs modeled included payor costs, hospital costs, and indirect costs. Benefits modeled included life-years (LYs) gained, quality-adjusted life-years (QALYs) gained, deaths avoided, and use of mechanical ventilation avoided. The primary analysis was performed from a payor perspective over a lifetime horizon; a secondary analysis was performed from a hospital perspective. The base-case analysis modeled the numeric differences in treatment effectiveness observed in the COV-BARRIER trial. Scenario analyses were also performed in which the clinical benefit of baricitinib was limited to the statistically significant reduction in mortality demonstrated in the trial.

Findings

In the base-case payor perspective model, an incremental total cost of 17,276 US dollars (USD), total QALYs gained of 0.6703, and total LYs gained of 0.837 were found with baricitinib + SOC compared with SOC alone. With the addition of baricitinib, survival was increased by 5.1% and the use of mechanical ventilation was reduced by 1.6%. The base-case incremental cost-effectiveness ratios were 25,774 USD/QALY gained and 20,638 USD/LY gained; a “mortality-only” scenario analysis yielded similar results of 26,862 USD/QALY gained and 21,433 USD/LY gained. From the hospital perspective, combination treatment with baricitinib + SOC was more effective and less costly than was SOC alone in the base case, with an incremental cost of 38,964 USD per death avoided in the mortality-only scenario.

Implications

In hospitalized patients with COVID-19 in the United States, the addition of baricitinib to SOC was cost-effective. Cost-effectiveness was demonstrated from both the payor and the hospital perspectives. These findings were robust to sensitivity analysis and to conservative assumptions limiting the clinical benefits of baricitinib to the statistically significant reduction in mortality demonstrated in the COV-BARRIER trial.

The association of quality of life and personality characteristics with adolescent metabolic syndrome: a cohort study

BACKGROUND

An increased prevalence of adolescent metabolic syndrome (MS) is associated with adulthood cardiovascular diseases. This study aimed to explore the potential relationship of quality of life (QoL) and personality traits with adolescent MS.

METHODS

A total of 1961 participants from Chongqing with an average age of 11.68 years old from a cohort study established in 2014 and followed up through 2019 were included. QoL information, Eysenck's personality questionnaire and MS components were collected.

RESULTS

A higher QoL domain score of physical activity ability (PAA) was a protective factor for both MS and MS score (all P < 0.01), which was mainly negatively correlated with the MS components of central obesity, diastolic blood pressure (DBP) and triglyceride levels, as well as positively correlated with high density lipoprotein cholesterol (HDL-C) level. The total QoL score was negatively correlated with triglyceride levels and positively correlated with DBP (all P < 0.01). High extraversion personality score was a protective factor against adolescent MS (P = 0.04) and MS score (P < 0.05), which were mainly negatively correlated with the MS components of waist circumference, systolic blood pressure and TGs, and positively correlated with HDL-C (all P ≤ 0.01).

CONCLUSIONS

QoL score and extraversion personality score were independent protective factors against both MS prevalence and MS score, suggesting that community intervention to improve the QoL and psychological health of children are essential.

The Effect of Lifestyle Intervention on Health-Related Quality of Life in Adults with Metabolic Syndrome: A Meta-Analysis

The aim of this meta-analysis was to assess the effects of a lifestyle intervention through health education on nutrition, physical activity, and healthy habits on physical and mental health-related quality of life (HRQoL), in adults with metabolic syndrome (MetS). The databases used were PubMed, WOS, and Scopus. The inclusion criteria were: observational, longitudinal and randomized clinical trial (RCT) study designs, adults (both sexes), with at least two criteria of MetS, lifestyle intervention and comparison with a control group, and a measurement of HRQoL with a validated questionnaire. We analyzed the Hedges’ g and SF-36 score. I² statistics were calculated and possible publication and small study biases were assessed using Egger’s test and funnel plots. Seven RCTs were selected for meta-analysis, based on 637 study participants. Significant improvements were found in the physical dimensions of the HRQoL scores for subjects in the active intervention compared to the group that received general lifestyle information (Hedges’ g 0.61, 95% confidence interval (CI) = 0.31–0.91). Mental health-related quality of life was also significantly improved in the intervention group compared with the control group (Hedges’ g 0.84, 95% CI = 0.64–1.03). In conclusion, our results suggest that, according to the RCTs selected for this meta-analysis, a lifestyle intervention significantly improves HRQoL in all its domains.

Frailty and Quality of Life in Older Adults with Metabolic Syndrome - Findings from the Healthy Older People Everyday (HOPE) Study

OBJECTIVES

Metabolic syndrome (MetS) and frailty are both associated with increased morbidity and mortality. Frailty is associated with reduced quality of life (QoL) but association of QoL with MetS have produced mixed results suggesting that other factors such as disease burden, obesity and depression may have a more significant influence. We aim to investigate the demographics of frail participants with MetS, and relationship between frailty and QoL in MetS.

METHODS

Cross-sectional population study involving 292 older adults ≥ 65 years with MetS. MetS was defined using the Modified ATP III for Asians which requires the presence of 3 or more of the following 5 components 1) waist circumference ≥ 90cm for males or ≥ 80cm for females, 2) TG ≥ 150mg/dL, 3) HDLc < 40mg/dL in males or < 50mg/dL in females, 4) blood pressure ≥ 130/85mmHg or use of anti-hypertensive medication, and 5) fasting plasma glucose ≥ 100mg/dL or use of pharmacological treatment for diabetes mellitus. Data were collected on demographics, frailty (FRAIL), QoL (Euroqol-5D), perceived health, functional status, cognition, Timed-Up-and-Go (TUG), and hand-grip strength (HGS).

RESULTS

40.4% of the participants were pre-frail (MetSprefrail) and 7.2% were frail (MetSfrail). MetSfrail were significantly older, had lower education level, higher polypharmacy burden and higher prevalence of diabetes. The prevalence of at least 1 activity of daily living impairment was 4 times higher, and depression 9 times higher than their robust counterparts. MetSfrail also had longer TUG, higher prevalence of poor grip strength and poor perceived health. After adjusting for age, gender and education, MetSfrail was significantly associated with much higher odds of EQ-5D moderate to extreme problems with mobility (Odds Ratio (OR) =10.99, CI 2.62-46.14), usual activities (OR=37.82, CI 3.77-379.04) and pain (OR=10.79, CI 3.18-36.62). EQ-5D Index Value and Perceived Health improved by 0.1 (Mean Difference (MD) =0.07, CI 0.04-0.10) and 6.0 (MD=6.01, CI 3.29-8.73) respectively as frailty status improved.

CONCLUSION

Frailty in MetS is associated with depression, polypharmacy, greater functional impairment, poorer QoL and perceived health. Frailty screening and personalized management is crucial in MetS as frailty may be a mediator for negative outcomes in MetS, and frailty may be reversible.

Depressive symptoms, psychological flexibility, and binge eating in individuals seeking behavioral weight loss treatment

Depressive symptoms and binge eating are both prevalent in weight management populations and may be associated with reduced benefit from behavioral weight loss, including higher attrition, more perceived barriers, lower weight loss, and increased weight regain. These two potential risk factors for poor behavioral weight loss outcomes may also be associated with each other as depressive symptoms may trigger binge eating, and binge eating-related distress could increase depressive symptoms. The depressive symptom-binge eating link has not been well studied in weight management samples, and psychological processes involved in this relationship have not yet been elucidated. Psychological flexibility, an individual's ability to be connected with and conscious of the present moment and to engage in values-consistent behavior even in the presence of difficult internal experiences, may be one psychological process that changes the depressive symptom-binge eating relationship. High psychological flexibility may be a protective factor in the association of depressive symptoms with binge eating. This study examined the relationship between depressive symptom and binge eating and a potential interactive role of psychological flexibility. Participants (N = 468, 76% female) completed self-report questionnaires of binge eating, depressive symptoms, and psychological flexibility at baseline prior to initiating behavioral weight loss. Depressive symptoms were positively associated with binge eating (B = 1.00, p < 0.001). Psychological flexibility had an interactive role (B = -0.03, p = 0.005). Among participants with minimal to mild depressive symptoms, those with higher psychological flexibility had less severe binge eating. Findings suggest that psychological flexibility may be a protective factor in the association between depressive symptoms and binge eating in the majority of individuals initiating behavioral weight loss. Psychological flexibility is a psychological process to consider targeting for enhancing efficacy of weight loss treatment, especially among individuals with minimal to mild depressive symptoms and binge eating behavior.

Health-related quality of life in individuals with metabolic syndrome: A cross-sectional study

INTRODUCTION AND OBJECTIVES

Metabolic syndrome (MetS) is a combination of various cardiovascular risk factors with a major impact on morbidity and premature mortality. However, the impact of MetS on self-reported health-related quality of life (HRQoL) is unknown. This study evaluated the HRQoL in a Spanish adult population aged 55 years and older with MetS.

METHOD

A cross-sectional analysis was performed with baseline data from the PREDIMED-Plus multicentre randomized trial. The participants were 6430 men and women aged 55-75 years with overweight/obesity (body mass index ≥27 and ≤40kg/m²) and MetS. The SF-36 questionnaire was used as a tool to measure HRQoL. Scores were calculated on each scale of the SF-36 by gender and age.

RESULTS

Participants showed higher scores in the social function (mean 85.9, 95% CI; 85.4-86.4) and emotional role scales (mean 86.8, 95% CI; 86.0-87.5). By contrast, the worst scores were obtained in the aggregated physical dimensions. In addition, men obtained higher scores than women on all scales. Among men, the worst score was obtained in general health (mean 65.6, 95% CI; 65.0-66.2), and among women, in body pain (mean 54.3, 95%CI; 53.4-55.2). A significant decrease was found in the aggregated physical dimensions score among participants 70-75 years old, but an increased one in the aggregated mental dimensions, compared to younger participants.

CONCLUSIONS

Our results reflect that the MetS may negatively affect HRQoL in the aggregated physical dimensions, body pain in women, and general health in men. However, this adverse association was absent for the psychological dimensions of HRQoL, which were less affected.

Health-related quality of life of primary care patients with depressive disorders

Background

Depressive disorders are known to impair health-related quality of life (HRQoL) both in the short and long term. However, the determinants of long-term HRQoL outcomes in primary care patients with depressive disorders remain unclear.

Methods

In a primary care cohort study of patients with depressive disorders, 82% of 137 patients were prospectively followed up for five years. Psychiatric disorders were diagnosed with SCID-I/P and SCID-II interviews; clinical, psychosocial and socio-economic factors were investigated by rating scales and questionnaires plus medical and psychiatric records. HRQoL was measured with the generic 15D instrument at baseline and five years, and compared with an age-standardized general population sample (n = 3707) at five years.

Results

Depression affected the 15D total score and almost all dimensions at both time points. At the end of follow-up, HRQoL of patients in major depressive episode (MDE) was particularly low, and the association between severity of depression (Beck Depression Inventory [BDI]) and HRQoL was very strong (r = −0.804). The most significant predictors for change in HRQoL were changes in BDI and Beck Anxiety Inventory (BAI) scores. The mean 15D score of depressive primary care patients at five years was much worse than in the age-standardized general population, reaching normal range only among patients who were in clinical remission and had virtually no symptoms.

Conclusions

Among depressive primary care patients, presence of current depressive symptoms markedly reduces HRQoL, with symptoms of concurrent anxiety also having a marked impact. For HRQoL to normalize, current depressive and anxiety symptoms must be virtually absent.

Abdominal obesity and hypertension are correlated with health-related quality of life in Taiwanese adults with metabolic syndrome

OBJECTIVE

Metabolic syndrome (MetS) gains more attention due to high prevalence of obesity, diabetes and hypertension among adults. Although obesity, diabetes and hypertension can certainly compromise health-related quality of life (HRQoL), the correlations of sociodemographic factors, quality of life and MetS remains unclear. This study aims to investigate the association between HRQoL and MetS in an Asian community of the sociodemographic characteristics.

RESEARCH DESIGN AND METHODS

We performed a cross-sectional study by recruiting 2588 Taiwanese patients aged ≥30 years between August 2015 and August 2017. Sociodemographic data and anthropometric variables were obtained from medical records and physical examination. Meanwhile, HRQoL was assessed by 36-Item Short-Form Health Survey questionnaires.

RESULTS

The overall prevalence of MetS was 32.8%. Multivariate analysis revealed that age ≥65 years (OR=1.987, p<0.001), body mass index (BMI) ≥24 kg/m² (OR=7.958, p<0.001), low educational level (OR=1.429, p=0.014), bad self-perceived health status (OR=1.315, p=0.01), and betel nut usage (OR=1.457, p=0.048) were associated with the development of MetS. For patients with MetS, the physical and mental health domains of HRQoL are negatively correlated with abdominal obesity and hypertension, respectively.

CONCLUSIONS

Adult MetS in Taiwan was associated with certain sociodemographic factors including older age, high BMI, low educational level, bad self-perceived health status, and betel nut use. Abdominal obesity and hypertension was correlated with HRQoL in patients with MetS.

Effect of comorbid depression on health-related quality of life of patients with chronic diseases: A South Korean nationwide study (2007-2015)

OBJECTIVE

Patients with chronic physical diseases often have concomitant depression. Depression influences an individual's health and his or her overall health-related quality of life (HRQoL). The extent to which depression incrementally worsens HRQoL in patients with ≥1 comorbid physical chronic diseases remains unclear.

METHODS

This cross-sectional study is based on data of 50,844 respondents (age, ≥19 years) who participated in the Korean National Health and Nutrition Examination Survey (KNHANES) (2007-2015). HRQoL was measured using the modified EuroQol five-dimensional (EQ-5D) score. Mean HRQoL scores were compared between subgroups of respondents with or without depression. The association between HRQoL and disease status was evaluated using multiple regression models after controlling for sociodemographic variables.

RESULTS

HRQoL score decreased when depression was concomitant. HRQoL score of respondents who had ≥3 chronic diseases with concomitant depression (mean = 0.83, SE = 0.010) were significantly lower (p = 0.002) than those of respondents who had ≥3 chronic diseases but no concomitant depression (mean = 0.87, SE = 0.007). Moreover, respondents with ≥3 chronic diseases comorbid with depression showed the largest negative association (coefficient = -0.133, p < 0.001) with HRQoL among all disease status groups.

CONCLUSION

Presence of depression incrementally worsened individual's HRQoL when comorbid with other physical diseases. Especially, depression showed substantial negative effect on HRQoL level in patients with ≥2 physical diseases.

Health-Related Quality of Life in Tehran Lipid and Glucose Study

CONTEXT

Beyond the objective outcomes of metabolic syndrome (MetS), the association between this syndrome and its patient-centered outcomes need to be investigated in Middle-Eastern countries. This report aims to summarize the Tehran lipid and glucose study (TLGS) findings regarding the association between MetS and health-related quality of life (HRQoL) and its influential factors through the past decade.

EVIDENCE ACQUISITION

The current review has been conducted on the TLGS published data regarding different aspects of the association between MetS and HRQoL in adult participants through the last decade. To assess HRQoL, the Iranian version of short form health survey (SF-36) was used. To define MetS the most commonly used insulin resistance (IR)-and waist circumference (WC) - based MetS definitions have been applied in the publications reviewed.

RESULTS

As a whole, MetS was a determinant of poor physical HRQoL only in women (OR: 1.78; 95% CI: 1.21 - 2.61), particularly in those with more component of MetS (P < 0.001). Results further showed that only reproductive aged women with MetS were more likely to report poor PCS compared to those without MetS even after adjusting for age (OR: 1.7, 95% CI: 1.0 - 3.0; P < 0.05). Different structures of MetS and physical HRQoL constructs in men and women as well as age and smoking with significant gender-specific effects on mental HRQoL were factors responsible for the gender specific pattern observed. Considering the duration of MetS, only women with intermittent MetS indicated higher risk for reporting poor PCS (OR: 2.75, 95% CI: 1.19 - 6.37; P < 0.001) compared to those without MetS. The observed sex-specific pattern used to detect poor HRQoL in those with MetS was confirmed by all WC-based definitions except for the American Heart Association/National Heart, Lung, and Blood Institute (AHA/NHLBI) definition. However, none of IR-based definitions could detect poor physical and mental HRQoL in either gender.

CONCLUSIONS

In summary, in the TLGS population, the association between MetS and HRQoL followed a sex specific pattern, mainly significant only in women and in the physical aspect.

Correlates and predictors of obesity-specific quality of life of former participants of a residential intensive lifestyle intervention

Introduction

The aim of this study was to investigate the relationship between weight loss during and after a unique type of weight loss intervention, namely, a residential intensive lifestyle intervention (ILI), and participants' obesity-specific health-related quality of life (HRQOL) several years after the intervention. In the residential ILI under investigation, participants attended a 10- to 12-week long course away from their daily living environment, namely, at Ubberup Folk High School located in Denmark.

Methods

A total of 79 former participants (31 male, mean age 36.6; SD = 12.7 years) who had participated in the intervention on average 5.3 (SD = 3.2) years ago were recruited for this study. They completed a questionnaire on weight-related quality of life (IWQOL-lite) and physical activity, as well as measurements of VO₂max, blood pressure, Homeostatic Model Assessment for Insulin Resistance, waist circumference and hand grip strength.

Results

The study results showed that weight change after the end of the intervention could predict HRQOL whereas how much weight they lost during the intervention could not. Furthermore, almost all of the investigated physiological factors were related to participants' current HRQOL. Waist circumference showed relationships with four of the five aspects of HRQOL.

Conclusion

Focusing on behavioural change, adhering to improved lifestyle and maintaining weight loss after the end of the intervention seem to be the key not only for cardio-metabolic risk factors but also for sustainable HRQOL.

Metabolic Correlates of Health-Related Quality of Life in Patients With Type 2 Diabetes Mellitus

BACKGROUND

The increasing prevalence of type 2 diabetes mellitus (T2DM) and associated metabolic complications lead to the development of a syndrome known as "metabolic syndrome" (MetS), which is considered as one of the major risk factor not only for the development of cardiovascular diseases but also have a great impact on the quality of life.

RESEARCH DESIGN AND METHODS

A descriptive, observational study involving the recruitment of patients with T2DM with and without MetS was carried out in outpatient department of endocrinology. The MetS was defined as per the National Cholesterol Education Program-Adult Treatment Panel III (NCEP-ATP III) criteria. Patients with T2DM were screened as per the American Diabetes Association (ADA; ie, fasting blood glucose [FBG] ≥ 126 mg/dL) and who were using oral antidiabetic drugs. Short Form-36 (SF-36) was used to assess the health-related quality of life (HRQoL).

RESULTS

Patients were grouped as T2DM with MetS (n = 100) and T2DM without MetS (n = 100). A greater significant decline was observed in physical component summary (PCS) and mental component summary (MCS) in patients with T2DM with MetS as compared to patients without MetS (P ≤ .05). Multiple linear regression analysis revealed that in patients with T2DM having MetS, age and waist circumference (WC) are independent predictors for worsening of both PCS and MCS aspects of health-related quality of life (HRQOL). In addition, high triglycerides and raised FBG were found to be correlated with the decline in PCS and MCS, respectively.

CONCLUSION

The study demonstrated that patients with T2DM with MetS have overall poor HRQOL as compared to patients with T2DM without MetS.

Association of the Cardiometabolic Staging System with Individual Engagement and Quality of Life in the US Adult Population

OBJECTIVE

The aim of this study was to examine the relationships of Cardiometabolic Disease Staging (CMDS), a validated five-stage system for assessing risk for diabetes, cardiovascular mortality, and all-cause mortality, with measures of individual engagement and health-related quality of life (HRQOL) in the US adult population.

METHODS

Data from the 2011-2014 National Health and Nutrition Examination Survey were used to derive the CMDS stages, five participant engagement measures, and four HRQOL measures among adult participants ≥ 40 years of age. Analyses accounted for the complex sampling design and sample weights.

RESULTS

Higher CMDS was associated with greater participant awareness of cardiometabolic risk, but after adjusting for covariates, only Stage 4 remained significant (odds ratio: 5.08; 95% CI: 3.25, 7.94). Higher CMDS was associated with receiving recommendations to engage in a healthy lifestyle, not meeting 2008 physical activity guidelines, and fewer leisure time moderate activities after controlling for covariates. For HRQOL measures, Stage 4 was associated with a higher likelihood of perceiving health as fair or poor (odds ratio: 4.85; 95% CI: 2.42, 9.73).

CONCLUSIONS

Higher CMDS was associated with greater individual awareness of risk, less leisure time physical activity, and worse self-rated health. CMDS is a clinically practical method for identifying individuals for targeted preventive strategies.

Lifestyle Intervention on Metabolic Syndrome and its Impact on Quality of Life: A Randomized Controlled Trial

Background

Lifestyle intervention programs can reduce the prevalence of metabolic syndrome (MetS) and, therefore, reduce the risk for cardiac disease, one of the main public health problems nowadays.

Objective

The aim of this study was to compare the effects of three types of approach for lifestyle change programs in the reduction of metabolic parameters, and to identify its impact on the quality of life (QOL) of individuals with MetS.

Methods

A randomized controlled trial included 72 individuals with MetS aged 30-59 years. Individuals were randomized into three groups of multidisciplinary intervention [Standard Intervention (SI) - control group; Group Intervention (GI); and Individual Intervention (II)] during 12 weeks. The primary outcome was change in the metabolic parameters, and secondarily, the improvement in QOL measures at three moments: baseline, 3 and 9 months.

Results

Group and individual interventions resulted in a significant reduction in body mass index, waist circumference, systolic blood pressure at 3 months and the improvement of QOL, although it was significantly associated with the physical functioning domain. However, these changes did not remain 6 months after the end of intervention. Depression and anxiety were significantly associated with worse QOL, although they showed no effect on the response to intervention.

Conclusion

Multidisciplinary intervention, especially in a group, might be an effective and economically feasible strategy in the control of metabolic parameters of MetS and improvement of QOL compared to SI, even in a dose-effect relationship.

Impact of Menopausal Status, Metabolic Syndrome and its Risk Factors on Impaired Quality of Life above Middle-aged Women

PURPOSE

This study explored influencing factors on quality of life (QoL) above middle-aged women in relation to demographic factors, health-related factors, menopausal status, metabolic syndrome (MS) and its risk factors.

METHODS

This study was secondary data analysis from the Sixth Korea National Health and Nutrition Examination Survey 2013~2015 that utilized a complex, multi-stage probability sample design. Study sample of 2,310 was inclusive of (28.8%) of women who were over 40. To evaluate the factors that would influence an impaired quality of life, χ² test, GLM, and logistic regression analysis were done.

RESULTS

Level of quality of life was lower in women with late post-menopause(over 10 years since menopause) than women with pre-menopause. Factors influencing impaired QoL were as follows: graduated middle school and elementary school or less (OR=2.43, 4.42, respectively, p<.05), no job (OR=1.92, p<.001), stress (OR=1.92, p=.001), depression (OR=1.93, p=.001), insufficient sleep (OR=1.64, p=.003), late post-menopause (OR=2.61, p=.044) and over 85cm of waist circumference (OR=1.76, p=.01).

CONCLUSION

These results suggest that late post-menopause may be an independent factor influencing an impaired QoL. To promote post-menopausal womens' health, a nursing strategy is required to teach women how to manage levels of stress, depression, insufficient sleep, and abdominal obesity through health education, nutritional counselling, and physical activity program.

Metabolic syndrome and quality of life: a systematic review

Objectives:

to present currently available evidence to verify the association between metabolic syndrome and quality of life.

Method:

Cochrane Library, EMBASE, Medline and LILACS databases were studied for all studies investigating the association with metabolic syndrome and quality of life. Two blinded reviewers extracted data and one more was chosen in case of doubt.

Results:

a total of 30 studies were included, considering inclusion and exclusion criteria, which involved 62.063 patients. Almost all studies suggested that metabolic syndrome is significantly associated with impaired quality of life. Some, however, found association only in women, or only if associated with depression or Body Mass Index. Merely one study did not find association after adjusted for confounding factors.

Conclusion:

although there are a few studies available about the relationship between metabolic syndrome and quality of life, a growing body of evidence has shown significant association between metabolic syndrome and the worsening of quality of life. However, it is necessary to carry out further longitudinal studies to confirm this association and verify whether this relationship is linear, or only an association factor.

Gender-Related Differential Effects of Obesity on Health-Related Quality of Life via Obesity-Related Comorbidities: A Mediation Analysis of a French Nationwide Survey

BACKGROUND

Negative effects of obesity on health-related quality of life (HRQoL) have been reported, especially in women, but the relative contribution of cardiometabolic and other obesity-related comorbidities to such effects remains unclear. Our objective was to model the association by sex between body mass index and HRQoL and to precisely quantify the indirect effects mediated by obesity-related comorbidities.

METHODS AND RESULTS

Data were drawn from the latest French Decennial Health Survey, a nationwide cross-sectional study conducted in 2003 (21 239 adults aged 25-64 years analyzed). HRQoL was measured by the 36-item short-form health survey questionnaire. A mediation analysis based on the counterfactual framework was performed to quantify the proportion of obesity effects on HRQoL mediated by related comorbidities, including cardiometabolic risk factors (diabetes mellitus, hypertension, dyslipidemia) and diseases (ischemic heart disease, cerebrovascular, and peripheral vascular disease), musculoskeletal disorders, and asthma. After multiple linear regression, inverse associations were found between increasing body mass index category and physically oriented and most mentally oriented 36-item short-form health survey dimensions, with evidence of greater effects in women. Mediation analysis revealed that obesity effects were significantly mediated by several comorbidities, more apparently in men (eg, proportion of obesity class II total effect mediated via cardiometabolic factors: general health 27.0% [men] versus 13.6% [women]; proportion of obesity class II total effect mediated via total count of comorbidities: physical functioning 17.8% [men] versus 7.7% [women] and general health 37.1% [men] versus 20.3% [women]).

CONCLUSIONS

Women have a greater overall impact of obesity on HRQoL, but with proportionally lower effects mediated by cardiometabolic and other obesity-related conditions, suggesting the possible role of other specific psychosocial processes.

The Combined Effects of Obesity, Abdominal Obesity and Major Depression/Anxiety on Health-Related Quality of Life: the LifeLines Cohort Study

BACKGROUND

Obesity and major depressive disorder (MDD)/anxiety disorders often co-occur and aggravate each other resulting in adverse health-related outcomes. As little is known about the potential effects of interaction between obesity and MDD and/or anxiety disorders on health-related quality of life (HR-QoL), this study was aimed at examining these combined effects.

METHODS

We collected data among N = 89,332 participants from the LifeLines cohort study. We categorized body weight using body mass index (kg/m2) as normal weight (18.5-24.99), overweight (25-29.9), mild obesity (30-34.9) and moderate/severe obesity (≥ 35); we measured abdominal obesity using a waist circumference of ≥102 and ≥ 88 cm for males and females, respectively. MDD and anxiety disorders were diagnosed with the Mini-International Neuropsychiatric Interview. HR-QoL was assessed using the RAND-36 questionnaire to compute physical and mental quality of life scores. We used binary logistic and linear regression analyses.

RESULTS

The combined effect of obesity and MDD and/or anxiety disorders on physical QoL was larger than the sum of their separate effects; regression coefficients, B (95%-confidence interval, 95%-CI) were: - 1.32 (-1.75; -0.90). However, the combined effect of obesity and major depression alone on mental QoL was less than the additive effect. With increasing body weight participants report poorer physical QoL; when they also have MDD and/or anxiety disorders participants report even poorer physical QoL. In persons without MDD and/or anxiety disorders, obesity was associated with a better mental QoL.

CONCLUSIONS

Obesity and MDD and/or anxiety disorders act synergistically on physical and mental QoL. The management of MDD and/or anxiety disorders and weight loss may be important routes to improve HR-QoL.

Obesity, metabolic abnormality, and health-related quality of life by gender: a cross-sectional study in Korean adults

PURPOSE

This study sought to compare the association between health-related quality of life (HRQoL) and four body health types by gender.

METHODS

The study included 6217 men and 8243 women over 30 years of age chosen from a population-based survey. Participants were grouped by body mass index and metabolic abnormality into four types: metabolically healthy normal weight, metabolically abnormal but normal weight (MANW), metabolically healthy obesity (MHO), and metabolically abnormal obesity (MAO). HRQoL was measured using the EQ-5D health questionnaire. The outcomes encompassed five dimensions (mobility, self-care, usual activity, pain/discomfort, and anxiety/depression), and the impaired HRQoL dichotomized by the EQ-5D preference score. Complex sample multivariate binary logistic regression analyses were conducted to adjust for sociodemographic variables, lifestyle factors, and disease comorbidity.

RESULTS

Among men, those in the MANW group presented worse conditions on all dimensions and the impaired HRQoL compared to other men. However, no significant effect remained after adjusting for relevant covariates. For women, those in the MAO group had the most adversely affected HRQoL followed by those females in the MHO group. The domain of mobility and impaired HRQoL variable of the MAO and MHO groups remained significant when controlling for all covariates in the model.

CONCLUSIONS

The MANW is the least favorable condition of HRQoL for men, suggesting that metabolic health may associate with HRQoL more than obesity for males. In women, the MAO and MHO groups had the most adversely affected HRQoL, implying that MHO is not a favorable health condition and that obesity, in general, may be strongly associated with HRQoL in women.

Health-Related Quality of Life in Relation to Obesity Grade, Type 2 Diabetes, Metabolic Syndrome and Inflammation

Background

Health-related quality of life (HR-QoL) may be compromised in obese individuals, depending on the presence of other complications. The aim of this study is to assess the effect of obesity-related conditions on HR-QoL. These conditions are i) grade of obesity with and without type 2 diabetes (T2D), ii) metabolic syndrome (MetS), and iii) level of inflammation.

Methods

From the Dutch LifeLines Cohort Study we included 13,686 obese individuals, aged 18–80 years. HR-QoL was measured with the RAND 36-Item Health Survey which encompasses eight health domains. We calculated the percentage of obese individuals with poor HR-QoL, i.e. those scoring below the domain and sex specific cut-off value derived from the normal weight population. Logistic regression analysis was used to calculate the probability of having poor domain scores according to the conditions under study.

Results

Higher grades of obesity and the additional presence of T2D were associated with lower HR-QoL, particularly in the domains physical functioning (men: odds ratios (ORs) 1.48–11.34, P<0.005, and women: ORs 1.66–5.05, P<0.001) and general health (men: ORs 1.44–3.07, P<0.005, and women: ORs 1.36–3.73, P<0.001). A higher percentage of obese individuals with MetS had a poor HR-QoL than those without MetS. Furthermore, we observed a linear trend between inflammation and the percentage of obese individuals with poor scores on the HR-QoL domains. Individuals with MetS were more likely to have poor scores in the domains general health, vitality, social functioning and role limitations due to emotional problems. Obese women with increased inflammation levels were more likely to have poor scores on all domains except role limitations due to emotional problems and mental health.

Conclusions

The impact of obesity on an individual’s quality of life is enhanced by grade of obesity, T2D, MetS and inflammation and are mainly related to reduced physical health. The mental well-being is less often impaired.

Factors associated with health-related quality of life among overweight and obese Korean women

Health-related quality of life (HRQOL) tends to be lower among individuals who are overweight and obese than those of normal weight, and women may be more vulnerable to lower HRQOL associated with obesity than men. Identifying factors associated with HRQOL may be crucial for improving HRQOL for overweight/obese women. We aimed to determine the factors associated with obesity-specific HRQOL among overweight/obese Korean women. A cross-sectional study was conducted with 125 women aged 20-64 years, who comprised a baseline sample in the Community-based Heart and Weight Management Trial. The data were collected from September 2010 to November 2011. The Weight Efficacy Lifestyle, Beck Depression Inventory-II, Interpersonal Social Evaluation List, and Impact of Weight on Quality of Life (IWQOL)-Lite scales were used to measure self-efficacy for weight control, depressive symptoms, social support, and HRQOL, respectively. Increased body mass index, lower self-efficacy for weight control, and higher levels of depressive symptoms were significantly associated with greater impairment in total IWQOL in the regression models. However, social support was not significantly associated with IWQOL. Along with weight loss strategies, other strategies for improving self-efficacy and alleviating depressive symptoms may be essential for improving HRQOL among overweight and obese women.

Rapid Screening of Psychological Well-Being of Patients with Chronic Illness: Reliability and Validity Test on WHO-5 and PHQ-9 Scales

This study intended to test the reliability and validity of two simple psychological screening scales, the World Health Organization Well-being Index (WHO-5) and the 9-item Patient Health Questionnaire (PHQ-9), in patients with chronic illness in Taiwan and to understand the psychological well-being of patients with chronic illness (e.g., metabolic syndrome) in Taiwan and the incidences of psychological problems that follow. The research design of this study was a descriptive cross-sectional study. The sample comprised 310 patients with metabolic syndrome (MS), aged 20 years or more, from the outpatient clinic of a municipal hospital in Taiwan. This study used questionnaires to collect basic information, including physiological indices, WHO-5 and PHQ-9 that were used. "Hospital Anxiety and Depression scale (HADS)," and "World Health Organization Quality of Life-Short-form Version for Taiwan (WHOQOL)". Results are as follows: (1) compared to PHQ-9, the reliability and validity of WHO-5 are better for screening the psychological well-being of patients with chronic illness. (2) The features of WHO-5 are high sensitivity, briefness, and ease-of-use. The incidence of depression in patients with metabolic syndrome was approximately 1.0-6.5%, which is significantly lower than that of western countries.

Manualised Cognitive Remediation Therapy for adult obesity: study protocol for a randomised controlled trial

BACKGROUND

Research has shown that obese individuals have cognitive deficiencies in executive function, leading to poor planning and impulse control, and decision-making difficulties. An intervention that could help reduce these deficits and in turn help weight loss maintenance is Cognitive Remediation Therapy for Obesity (CRT-O). We aim to examine the efficacy of manualised CRT-O, which is intended to improve executive function, enhance reflective practice and help weight loss maintenance.

METHODS/DESIGN

A randomised controlled trial (registered with the Australian New Zealand Clinical Trials Registry) will be conducted. First, 90 obese adults (body mass index >30 kg/m2) in the community will receive three weekly sessions of a group Behaviour Weight Loss Treatment (BWLT), and then will be randomised either to receive CRT-O or to enter a no-treatment control group. CRT-O training will comprise twice-weekly sessions of 45 minutes over a 4 to 6 week period, for a total of eight sessions. Measurement points will be at baseline, post CRT-O (or 4 to 6 weeks after BWLT for the no-treatment control), 3 months post treatment and 1 year post treatment. The primary outcome will be executive function and secondary outcome measures will include participants' body mass index, hip to waist ratio, eating behaviours and quality of life.

DISCUSSION

This is the first study of its kind to examine the efficacy of Cognitive Remediation Therapy for obese adults through a randomised controlled trial.

Disease-specific quality of life evaluation and its determinants in Cushing's syndrome: what have we learnt?

Cushing's syndrome (CS) has a considerable negative impact on patient health-related quality of life (HRQoL). Two disease-specific instruments (the CushingQoL and the Tuebingen CD-25 questionnaire) are now available to assess the impact of the disease and its treatment on HRQoL. The purpose of this review was to summarize the characteristics of the studies which have used these two instruments to date and summarize their findings regarding (a) the determinants of disease-specific HRQoL in patients with CS and (b) the impact of treatment for CS on disease-specific HRQoL. A total of 7 studies were identified, 5 with the CushingQoL and 2 with the Tuebingen CD-25. Most were observational studies, though the CushingQoL had been used in one randomized clinical trial. In terms of clinical factors, there was some evidence for an association between UFC levels and disease-specific HRQoL, though the presence and strength of the association varied between studies. There was also some evidence that a more recent diagnosis of CS could lead to poorer HRQoL, and that length of time with adrenal insufficiency may also affect HRQoL. There was no evidence for an impact on disease-specific HRQoL of etiology or of the clinical signs and symptoms associated with CS, such as bruising, rubor, and fat deposits. One factor which did have a significant negative effect on HRQoL was the presence of depression. No clear picture emerged as to the effect of demographic variables such as age and gender on HRQoL scores, though there was some evidence for poorer HRQoL in female patients. As regards treatment, the two interventions studied to date (transsphenoidal surgery and pasireotide) both showed significant gains in HRQoL, with moderate to large effect sizes. This type of review is useful in summarizing knowledge to date and suggesting future research directions.

Ascending dose-controlled trial of beloranib, a novel obesity treatment for safety, tolerability, and weight loss in obese women

OBJECTIVE

Evaluate the safety and tolerability of beloranib, a fumagillin-class methionine aminopetidase-2 (MetAP2) inhibitor, in obese women over 4 weeks.

DESIGN AND METHODS

Thirty-one obese (mean BMI 38 kg/m2) women were randomized to intravenous 0.1, 0.3, or 0.9 mg/m2 beloranib or placebo twice weekly for 4 weeks (N = 7, 6, 9, and 9).

RESULTS

The most frequent AEs were headache, infusion site injury, nausea, and diarrhea. Nausea and infusion site injury occurred more with beloranib than placebo. The most common reason for discontinuation was loss of venous access. There were no clinically significant abnormal laboratory findings. In subjects completing 4 weeks, median weight loss with 0.9 mg/m2 beloranib was -3.8 kg (95% CI -5.1, -0.9; N = 8) versus -0.6 kg with placebo (-4.5, -0.1; N = 6). Weight change for 0.1 and 0.3 mg/m2 beloranib was similar to placebo. Beloranib (0.9 mg/m2) was associated with a significant 42 and 18% reduction in triglycerides and LDL-cholesterol, as well as improvement in C-reactive protein and reduced sense of hunger. Changes in β-hydroxybutyrate, adiponectin, leptin, and fibroblast growth factor-21 were consistent with the putative mechanism of MetAP2 inhibition. Glucose and blood pressure were unchanged.

CONCLUSIONS

Beloranib treatment was well tolerated and associated with rapid weight loss and improvements in lipids, C-reactive protein, and adiponectin.

Changes in eating, physical activity and related behaviors in a primary care-based weight loss intervention

OBJECTIVE

To examine changes in eating behaviors and physical activity, as well as predictors of weight loss success, in obese adults who participated in a 2-year behavioral weight loss intervention conducted in a primary care setting.

DESIGN

A longitudinal, randomized controlled, multisite trial.

SUBJECTS

Three hundred ninety obese (body mass index, 30-50 kg m(-2)) adults, ≥ 21 years, in the Philadelphia region.

METHODS

Participants were assigned to one of three interventions: (1) Usual Care (quarterly primary care provider (PCP) visits that included education on diet and exercise); (2) Brief Lifestyle Counseling (quarterly PCP visits plus monthly lifestyle counseling (LC) sessions about behavioral weight control); or (3) Enhanced Brief LC (the previous intervention with a choice of meal replacements or weight loss medication).

RESULTS

At month 24, participants in both Brief LC and Enhanced Brief LC reported significantly greater improvements in mean (± s.e.) dietary restraint than those in Usual Care (4.4 ± 0.5, 4.8 ± 0.5 and 2.8 ± 0.5, respectively; both P-values ≤ 0.016). The percentage of calories from fat, along with fruit and vegetable consumption, did not differ significantly among the three groups. At month 24, both the Brief LC and Enhanced Brief LC groups reported significantly greater increases than usual care in energy expenditure (kcal per week) from moderately vigorous activity (+593.4 ± 175.9, +415.4 ± 179.6 and -70.4 ± 185.5 kcal per week, respectively; both P-values ≤ 0.037). The strongest predictor of weight loss at month 6 (partial R(2)=33.4%, P<0.0001) and at month 24 (partial R(2)=19.3%, P<0.001) was food records completed during the first 6 months. Participants who achieved a 5% weight loss at month 6 had 4.7 times greater odds of maintaining a ≥ 5% weight loss at month 24.

CONCLUSIONS

A behavioral weight loss intervention delivered in a primary care setting can result in significant weight loss, with corresponding improvements in eating restraint and energy expenditure. Moreover, completion of food records, along with weight loss at month 6, is a strong predictor of long-term weight loss.

Effectiveness of web-based self-disclosure peer-to-peer support for weight loss: randomized controlled trial

BACKGROUND

Obesity is one of the most common public health problems in the industrialized world as a cause of noncommunicable diseases. Although primarily used for one-on-one communication, email is available for uninterrupted support for weight loss, but little is known about the effects of dietitian group counseling for weight control via the Internet.

OBJECTIVE

We developed a Web-based self-disclosure health support (WSHS) system for weight loss. This study aims to compare the effect of weight change between those using the WSHS and those using the email health support (EHS).

METHODS

This study was designed as an open prospective individual randomized controlled trial. Eligible participants were aged 35 to 65 years with a body mass index (BMI) of ≥25.0 in their latest health examination. Participants were randomly assigned to either the WSHS group or the EHS group. Thirteen registered dietitians under the direction of a principal dietitian each instructed 6 to 8 participants from the respective groups. All participants in the WSHS group could receive nutritional advice and calculate their nutritive intake from a photograph of a meal on their computer screen from the Internet sent to them by their dietitian, receive supervision from the registered dietitian, and view fellow participants' weight changes and lifestyle modifications. In the EHS group, a participant could receive one-on-one nutritional advice and calculate his/her nutritive intake from the photograph of a meal on computer screen sent by email from his/her dietitian, without being able to view fellow participants' status. The follow-up period was 12 weeks for both groups. The primary outcome measure was change in body weight. The secondary outcome measure included changes in BMI and waist circumference. The intergroup comparison of the changes before and after intervention was evaluated using analysis of covariance.

RESULTS

A total of 193 participants were randomly assigned to either the WSHS group (n=97) or the EHS group (n=96). Ten from the WSHS group and 8 from the EHS group dropped out during the study period, and the remaining 87 in the WSHS group and 88 in the EHS group were followed up completely. Weight loss was significantly greater in the WSHS group than in the EHS group (-1.6 kg vs -0.7 kg; adjusted P=.04). However, there were few differences in waist circumference between the 2 groups. (-3.3 cm vs -3.0 cm; adjusted P=.71).

CONCLUSIONS

Our newly developed WSHS system using forced self-disclosure had better short-term weight loss results. Further study in a longer-term trial is necessary to determine what effects this type of intervention might have on long-term cardiovascular disease.

Metabolic syndrome and impaired health-related quality of life and in non-Hispanic White, non-Hispanic Blacks and Mexican-American Adults

OBJECTIVE

We examined the relationship between metabolic syndrome (MetS) and impaired health-related quality of life (HRQoL) in non-Hispanic Whites (NHW), non-Hispanic Black (NHB), and Mexican-Americans (MA).

METHODS

Data (n=5170) from 2009-2010 NHANES were used. Subjects perceived poor overall health (POH), poor physical health (PPH), and poor mental health (PMH) status in the past 30 days were used as indices of impaired HRQoL. Race/ethnic-specific associations between MetS and indices of HRQoL were determined using prevalence odds ratios (POR) from logistic regression models. Statistical adjustments were made for age, sex, education, marital status, income and smoking.

RESULTS

Rates of POH, PPH and PMH in the past 30 days increased linearly with increased number of components of MetS in NHW, NHB and MA. MetS was associated with increased odds of PPH in NHW (POR=2.34; 95% CI=1.73-3.17) and MA (POR=1.65; 95% CI=1.09-2.50); increased odds of PPH in NHW (POR=1.65; 95% CI=1.18-2.31), NHB (POR=1.83; 95% CI=1.01-3.35), and MA (POR=1.67; 95% CI=1.09-2.83); and increased odds of PMH in NHW (POR=1.50; 95% CI=1.08-2.08), NHB (POR=2.28; 95% CI=1.29-4.01), and MA (POR=1.44; 95% CI=0.80-2.59). Upon adjustment for other independent variables, smoking and lack of education were found associated with increased odds of impaired HRQoL.

CONCLUSIONS

MetS is associated with POH, PPH, and PMH in American adults. From clinical standpoint, this study further suggests that HRQoL should be considered in the management of subjects with MetS. Robust public health programs designed to reduce the prevalence of MetS may help in reducing impaired HRQoL, including POH, PPH, and PMH in American adults who have MetS.

Characteristics of abdominal obesity in persons with spinal cord injury

Objective

To investigate the characteristics of community-dwelling spinal cord injury (SCI) persons with obesity, including diet, socioeconomic factors, weight reduction method, and frequency of body weight and abdominal circumference measurements.

Methods

We developed a questionnaire based on 'the Fourth Korea National Health and Nutrition Examination Survey, 2009'. A total of 371 community-dwelling SCI persons were enrolled in this study. Inclusion criteria were SCI persons older than 20 years with more than 1 year elapsed since the injury. Trained investigators visited SCI persons' home to complete the questionnaire and measure abdominal obesity (AO) as defined by the waist circumference.

Results

Prevalence of AO was 29.2% in SCI persons and 27.4% in the general population (GP), showing no significant difference. Education showed correlation with AO in both SCI persons and the GP. The injury level, type of injury and income did not show any correlation with AO in SCI persons. Only 28.8% and 48.8% of SCI persons measured their waist circumference and body weight within the past year, respectively. Also, SCI persons with AO thought that their body was less obese compared to persons with AO in the GP (p<0.001). The method of weight reduction was diet modification in 53.6% of SCI persons with AO, which was higher than 37.1% of persons with AO in the GP.

Conclusion

In SCI persons, obesity perception as well as socioeconomic factors correlated with AO, but these were not relevant factors in the GP. Therefore, development of a specific and intensive weight control program for SCI persons is necessary.

Health and health-related quality of life among treatment-seeking overweight and obese adults: associations with internalized weight bias

BACKGROUND

Weight bias is widespread and has numerous harmful consequences. The internalization of weight bias has been associated with significant psychological impairment. Other forms of discrimination, such as racial and anti-gay bias, have been shown to be associated with physical health impairment. However, research has not yet examined whether internalized weight bias is associated with physical as well as psychological impairment in health-related quality of life.

METHODS

Participants included 120 treatment-seeking overweight and obese adults (mean body mass index = 35.09; mean age = 48.31; 68% female; 59% mixed or Asian ethnicity). Participants were administered measures of internalized weight bias and physical and mental health-related quality of life, and they were assessed for the presence of chronic medical conditions, use of prescription and non-prescription medications, and current exercise.

RESULTS

Internalized weight bias was significantly correlated with health impairment in both physical (r = -.25) and mental (r = -.48) domains. In multivariate analyses controlling for body mass index, age, and other physical health indicators, internalized weight bias significantly and independently predicted impairment in both physical (β = -.31) and mental (β = -.47) health.

CONCLUSIONS

Internalized weight bias was associated with greater impairment in both the physical and mental domains of health-related quality of life. Internalized weight bias also contributed significantly to the variance in physical and mental health impairment over and above the contributions of BMI, age, and medical comorbidity. Consistent with the association between prejudice and physical health in other minority groups, these findings suggest a link between the effects of internalized weight-based discrimination and physical health. Research is needed on strategies to prevent weight bias and its internalization on both a societal and individual level.

Health-related quality of life in adults with metabolic syndrome: the Korea national health and nutrition examination survey, 2007-2008

BACKGROUND/AIMS

An association between metabolic syndrome and impaired health-related quality of life (HRQoL) is still controversial. We investigated the association between metabolic syndrome in itself and HRQoL in the Korean adult population.

METHODS

The study is a cross-sectional analysis of 8,941 adults ≥19 years of age who participated in the 2007 and 2008 Korean National Health and Nutrition Examination Survey. EuroQoL five-dimension (EQ-5D), the EQ-5D index and the EQ visual analogue scale (EQ VAS) were used to assess HRQoL.

RESULTS

The prevalence of metabolic syndrome was 26.2%. Compared to the participants without metabolic syndrome, those with metabolic syndrome were older and comprised a higher proportion of men. Moreover, participants with metabolic syndrome were more likely to have a lower education level, to be current smokers, to have activity limitation and to have more frequent metabolic abnormalities and comorbidities. Metabolic syndrome was associated with HRQoL based on EQ-5D and EQ VAS in simple regression analysis. However, metabolic syndrome was not significantly associated with HRQoL after adjusting for age, sex, smoking status, income, education level, marital status, obesity, diabetes mellitus, stroke, history of heart disease and chronic kidney disease for EQ-5D, and in addition history of depression for EQ VAS.

CONCLUSION

Metabolic syndrome in itself was not associated with impaired HRQoL after adjusting for confounding variables such as socio-demographic factors, medical comorbidities and obesity.

Psychological disturbances and quality of life in obese and infertile women and men

Anovulatory cycles and endometriosis are the main causes of female infertility. The most frequently anovulatory cycles are related to polycystic ovary syndrome (PCOS) commonly associated with obesity and hormonal disturbances in the course of obesity. Recently published studies revealed that infertility affects about one in six couples during their lifetime and is more frequent in obese. Obesity is also associated with male infertility related to erectile dysfunction, hormonal disturbances and lower semen quality. Any of these above mentioned disorder is the important risk factor of psychological disturbances and poor quality of life among women and men in the reproductive age. On the other hand the mood disorders may exacerbate the hormonal disturbances and worsen the effectiveness of infertility management. Infertility, its therapy with accompanying psychological disturbances may also significantly affect the partners relationships. The review summarize the results described in the current literature on the association between obesity and infertility and psychological disturbances as well as their impact on quality of life and sexual functioning in women and men. Moreover, the impact of infertility and psychological disturbances on partners relationships is discussed.
