Weight loss is associated with improved quality of life among rural women completers of a web-based lifestyle intervention

Tirzepatide Was Associated with Improved Health-Related Quality of Life in Adults with Obesity or Overweight and Type 2 Diabetes: Results from the Phase 3 SURMOUNT-2 Trial

INTRODUCTION

In SURMOUNT-2, a phase 3, randomized clinical trial, tirzepatide treatment resulted in clinically meaningful reduction in bodyweight among people with obesity or overweight and T2D. The current analysis evaluated the effects of tirzepatide treatment on self-reported health-related quality of life (HRQoL) outcomes among SURMOUNT-2 participants.

METHODS

SURMOUNT-2 participants were randomly assigned (1:1:1) to receive either tirzepatide 10 mg (n = 312), tirzepatide 15 mg (n = 311), or placebo (n = 315) for 72 weeks as an adjunct to diet and exercise. Self-reported HRQoL was assessed in terms of changes from baseline to week 72 in Short Form-36 Version 2 Health Survey acute form (SF-36v2), Impact of Weight on Quality of Life-Lite-Clinical Trials Version (IWQOL-Lite-CT), EQ-5D 5-level Version (EQ-5D-5L) Health State Index (UK) and associated EQ visual analog scale (VAS), and Patient Global Impression of Status (PGIS) for Physical Activity. Post hoc analyses evaluated changes in HRQoL outcomes by categorical percent weight reduction targets (> 0 to < 5%, ≥ 5%, ≥ 10%, ≥ 15%, ≥ 20%, ≥ 25%, and ≥ 30%) and by self-reported baseline physical function limitations (based on PGIS) among tirzepatide-treated participants.

RESULTS

At week 72, tirzepatide treatment was associated with significantly larger improvements than placebo in the SF-36v2 Physical Component Summary score, SF-36v2 physical functioning, bodily pain, general health, vitality, and social functioning domain scores, all IWQOL-Lite-CT scores, and EQ VAS score. Tirzepatide-treated participants who achieved greater weight reduction targets showed numerically larger improvements in HRQoL scores relative to those with lower percent weight reduction. For all HRQoL measures, participants with physical function limitations at baseline showed greater improvements than those without limitations.

CONCLUSIONS

Tirzepatide treatment was associated with improved self-reported HRQoL outcomes compared with placebo among people with obesity or overweight with T2D. Participants achieving greater bodyweight reductions and those with physical function limitations at baseline showed greater improvements in HRQoL.

Exploring the Nutrition Care Journey of People Living With Obesity in Acute Care

BACKGROUND

Recent studies show a high prevalence in hospital populations and best practice evidence indicates that people living with obesity should receive dietetic advice. However, patients often do not receive this care in acute settings. Understanding the experiences of people living with obesity is crucial to designing successful strategies for management.

OBJECTIVE

This qualitative study aimed to understand the experience of nutrition care for patients living with obesity in the acute hospital setting and to redesign an optimised patient journey using a design approach. Using patient journey mapping, nutrition care across the inpatient admission was explored. A lived experience perspective was applied to reflect on the patient journey and interactions of patients with dietetic services in the acute setting. A co-creation session was conducted with dietitians and consumers to redesign the patient journey.

RESULTS

The patient journey revealed that for patients living with obesity, discussions about weight were absent from the journey from all healthcare professionals. For patients receiving dietetic care, the Nutrition Care Process was followed; nutrition intervention focused on acute nutrition issues with increased energy and protein prescription: a lack of goal setting and absence of discharge planning. The redesign of the nutrition care journey identified pivot points in the pathway to support engagement in obesity-related care.

CONCLUSION

The findings from this study provide new insights into current nutrition care for people living with obesity in the acute setting. These findings can inform future education, research and advocacy for practice changes to improve dietetic care for people living with obesity.

What internet- and mobile-based interventions are currently available for adults with overweight or obesity experiencing symptoms of depression? A systematic review

Given the high prevalence of overweight and obesity and high comorbidity of depressive symptoms, there is a need for low-threshold, accessible care approaches for people with overweight/obesity aimed at improving mental health. Internet and mobile-based interventions (IMI) represent an innovative complementary treatment option. This review systematically searches for IMI aimed at improving mental health in people with overweight/obesity. We conducted a systematic literature search according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) criteria in the databases MEDLINE, Cochrane Library, PsycINFO, Web of Science and Google Scholar. Randomized controlled trials (RCTs) of IMI for adults with overweight/obesity and comorbid depressive symptoms aiming at improving mental health were screened and extracted. Study quality was assessed with RoB 2 (revised Cochrane Risk of Bias tool in RCTs). After excluding duplicates, n = 790 results were included in title and abstract screening. After full-text-screening of n = 26 studies, n = 3 RCT studies were included. All interventions aimed to reduce both weight and depressive symptoms. In two RCTs, a significant reduction in both depressive symptoms and weight was achieved. One RCT indicated a significant reduction in depressive symptoms, but not in weight. Two intervention had a duration of 6 months and were guided by health carers, the third takes 3 months and can be used without professional guidance. There is evidence that IMI are effective in improving mental health for people with overweight/obesity and comorbid depressive symptoms. However, currently there are few interventions aiming at reducing depressive symptoms, all targeting English-speaking people. As IMI for depressive symptoms can be easily integrated in the somatic therapy of obesity as additional option and has high public health potential, target group-adapted and low-threshold accessible interventions in different languages should be developed and implemented for improving mental health in people with overweight/obesity.

Addressing rural health disparities by optimizing "high-touch" intervention components in digital obesity treatment: The iREACH Rural study

BACKGROUND

Rural residents are more impacted by obesity and related comorbidities than their urban counterparts. Digital weight management interventions may produce meaningful weight loss among rural residents.

OBJECTIVES

The iREACH Rural Study aims to identify "high-touch" component(s) that contribute to meaningful weight loss (≥1.5 kg) at 6-months, over and above what the 24-week core online program produces. Three treatment components are assessed: group video sessions (yes/no); self-monitoring feedback (counselor-crafted/pre-scripted, modular); and individual coaching calls (yes/no).

DESIGN

The iREACH Rural Study is a factorial experiment (n = 616).

METHODS

Participants receive up to 3 "high-touch" components (weekly synchronous facilitated group video sessions, weekly counselor-crafted self-monitoring feedback, and individual coaching calls) to determine which contribute meaningfully to 6-month weight loss. Participants complete assessments at baseline, 2 months, 6 months, and 12 months. Weight loss at 6 months (primary outcome) and 12 months (secondary outcome) is measured by Bluetooth-enabled scales. The study seeks to identify the weight loss approach for underserved rural residents which optimizes weight change outcomes and also examines costs associated with delivering different treatment constellations.

SUMMARY

The iREACH Rural Study is the first of its kind to isolate digital weight loss intervention components to determine which meaningfully contribute to long-term weight loss among rural residing individuals. The results may be used to refine digital weight loss programs by enhancing their effectiveness to allow broad dissemination.

Effect of aerobic and resistive exercise on lipid profile and quality of life in overweight breastfeeding women: A randomized controlled trial

BACKGROUND

Breastfeeding provides benefits for both mothers and babies. However, many women experience postpartum weight gain, unfavorable lipid profiles, and other postpartum problems that can adversely impact their overall quality of life (QoL).

OBJECTIVE

To examine the effect of adding aerobic and resistive exercise to faradic stimulation and nutritional counseling on lipid profile and QoL in overweight breastfeeding women.

SUBJECTS AND METHODS

Fifty-four breastfeeding women were randomly allocated into two equally sized groups. Group A underwent abdominal faradic stimulation along with nutritional counseling for 12 weeks, whereas Group B received identical faradic stimulation and nutritional counseling and engaged in a combined aerobic and resistive exercise program for the same duration. Before and after treatment, the following anthropometric measurements were evaluated: body mass index (BMI), waist-to-hip ratio (W/H); lipid profile analysis, such as high-density lipoprotein (HDL), low-density lipoprotein (LDL), and triglycerides (TG); and the Short Form 36 Health Survey Questionnaire (SF-36).

RESULTS

All outcome measures demonstrated significant improvements within the two groups (p < 0.05). Group B showed more significant reductions in BMI, W/H ratio, and LDL, along with greater significant increases in the SF-36 domain scores for physical functioning, physical health problems, bodily pain, general health, energy/fatigue, social activity, mental health, and the total SF-36 score (p < 0.05) compared to group A post-treatment. However, there were no significant differences in HDL, TG, and the score of the emotional wellbeing domain of the SF-36 between the groups after treatment (p > 0.05).

CONCLUSION

12-week aerobic and resistive exercise is effective in reducing the BMI, W/H ratio, and LDL levels and enhancing the QoL in overweight breastfeeding women.

A predictive model for medium-term weight loss response in people with type 2 diabetes engaging in behavioural weight management interventions

AIMS

To develop and evaluate prediction models for medium-term weight loss response in behavioural weight management programmes.

MATERIALS AND METHODS

We conducted three longitudinal analyses using the Action for HEalth in Diabetes (LookAHEAD) trial, Weight loss Referrals for Adults in Primary care (WRAP) trial, and routine data from the National Health Service Greater Glasgow and Clyde Weight Management Service (NHS-GGCWMS). We investigated predictors of medium-term weight loss (>5% body weight) over 3 years in NHS-GGCWMS and, separately, predictors of weight loss response in LookAHEAD over 4 years. We validated predictors in both studies using WRAP over 5 years. Predictors of interest included demographic and clinical variables, early weight change in-programme (first 4 weeks) and overall in-programme weight change.

RESULTS

In LookAHEAD and WRAP the only baseline variables consistently associated with weight loss response were female sex and older age. Of 1152 participants in NHS-GGCWMS (mean age 57.8 years, 60% female, type 2 diabetes diagnosed for a median of 5.3 years), 139 lost weight over 3 years (12%). The strongest predictor of weight loss response was early weight change (odds ratio 2.22, 95% confidence interval 1.92-2.56) per 1% weight loss. Losing 0.5% weight in the first 4 weeks predicted medium-term weight loss (sensitivity 89.9%, specificity 49.5%, negative predictive value 97.3%). Overall in-programme weight change was also associated with weight loss response over 3 years in NHS-GGCWMS and over 5 years in WRAP.

CONCLUSIONS

Not attaining a weight loss threshold of 0.5% early in weight management programmes may identify participants who would benefit from alternative interventions.

The Association Between Appetite and Quality of Life in Adults with Obesity or Severe Obesity Post-Sleeve Gastrectomy Procedure: A Cross-Sectional Study

Background

Sleeve gastrectomy (SG) is considered as the most common bariatric procedure in Saudi Arabia. It is a non-reversible procedure defined as removal of a large portion of the stomach.

Objective

The objective of the current study is to compare the appetite and quality of life (QoL) between adults' post-sleeve gastrectomy and obese/morbidly obese adults (pre-SG).

Methods

A cross-sectional study design was conducted in adults (aged between 18 and 65 years), post-sleeve gastrectomy (n = 80, 41 Males and 39 Females) and obese group (n = 60, 28 Males and 32 Females). The study population was recruited from the bariatric surgery clinic of King Abdullah Bin Abdul-Aziz University Hospital. A self-reported questionnaire was collected that included a visual analogue scale (VAS) to assess the appetite level, and SF-36 QoL questionnaire.

Results

No significant differences were found in age and gender between the study groups (p > 0.05). The median score feeling of fullness was significantly higher in the SG group (77.5, IQR: 48 and 50, IQR: 40, respectively) than in the obese group (p < 0.001). The amount of food eaten was statistically lower in the SG group (30, IQR: 20) than the obese group (50, IQR: 60) (p = 0.005). Patients post SG had significantly higher QoL scores in all physical and mental scales, physical component summary and mental component summary (p < 0.003).

Conclusion

Patients post SG have improved appetite and QoL. Satiety, less prospective food consumption, BMI, age, gender and comorbidities are associated with QoL. Future studies are needed to compare the QoL in post-SG patients with the normative values of the QoL in Saudi Arabia.

Economic Evaluation of a Personalized Nutrition Plan Based on Omic Sciences Versus a General Nutrition Plan in Adults with Overweight and Obesity: A Modeling Study Based on Trial Data in Denmark

BACKGROUND

Since there is no diet that is perfect for everyone, personalized nutrition approaches are gaining popularity to achieve goals such as the prevention of obesity-related diseases. However, appropriate choices about funding and encouraging personalized nutrition approaches should be based on sufficient evidence of their effectiveness and cost-effectiveness. In this study, we assessed whether a newly developed personalized plan (PP) could be cost-effective relative to a non-personalized plan in Denmark.

METHODS

Results of a 10-week randomized controlled trial were combined with a validated obesity economic model to estimate lifetime cost-effectiveness. In the trial, the intervention group (PP) received personalized home-delivered meals based on metabolic biomarkers and personalized behavioral change messages. In the control group these meals and messages were not personalized. Effects were measured in body mass index (BMI) and quality of life (EQ-5D-5L). Costs [euros (€), 2020] were considered from a societal perspective. Lifetime cost-effectiveness was assessed using a multi-state Markov model. Univariate, probabilistic sensitivity, and scenario analyses were performed.

RESULTS

In the trial, no significant differences were found in the effectiveness of PP compared with control, but wide confidence intervals (CIs) were seen [e.g., BMI (-0.07, 95% CI -0.51, 0.38)]. Lifetime estimates showed that PP increased costs (€520,102 versus €518,366, difference: €1736) and quality-adjusted life years (QALYs) (15.117 versus 15.106, difference: 0.011); the incremental cost-utility ratio (ICUR) was therefore high (€158,798 to gain one QALY). However, a 20% decrease in intervention costs would reduce the ICUR (€23,668 per QALY gained) below an unofficial gross domestic product (GDP)-based willingness-to-pay threshold (€47,817 per QALY gained).

CONCLUSION

On the basis of the willingness-to-pay threshold and the non-significant differences in short-term effectiveness, PP may not be cost-effective. However, scaling up the intervention would reduce the intervention costs. Future studies should be larger and/or longer to reduce uncertainty about short-term effectiveness.

Weight loss maintenance after a digital commercial behavior change program (Noom Weight): Observational cross-sectional survey study

Background

Behavioral weight loss programs often lead to significant short-term weight loss, but long-term weight maintenance remains a challenge. Most weight maintenance data come from clinical trials, in-person programs, or general population surveys, but there is a need for better understanding of long-term weight maintenance in real-world digital programs.

Methods

This observational survey study examined weight maintenance reported by individuals who had used Noom Weight, a digital commercial behavior change program, and identified factors associated with greater weight maintenance. The cross-sectional survey was completed by 840 individuals who had lost at least 10% of their body weight using Noom Weight 6-24 months prior.

Results

The study found that 75% of individuals maintained at least 5% weight loss after 1 year, and 49% maintained 10% weight loss. On average, 65% of initial weight loss was maintained after 1 year and 57% after 2 years. Habitual behaviors, such as healthy snacking and exercise, were associated with greater weight maintenance, while demographic factors were not.

Conclusion

This study provides real-world data on the long-term weight maintenance achieved using a fully digital behavioral program. The results suggest that Noom Weight is associated with successful weight maintenance in a substantial proportion of users. Future research will use a randomized controlled trial to track weight maintenance after random assignment and at a 2 year follow-up.

Relationship between body mass index and spinal pathology in community-dwelling older adults

PURPOSE

To clarify the relationship between body mass index (BMI) and spinal pathologies including spinal sagittal balance, back extensor strength (BES), paraspinal muscle mass, prevalent vertebral fracture, disc degeneration, Modic changes, low back pain, and quality of life (QOL) in community-dwelling older adults.

METHODS

This study included 380 participants (age: ≥ 65 years, male/female: 152/228) from the Shiraniwa Study. Multivariate nonlinear regression analysis was used to investigate the relationship between BMI and sagittal vertical axis (SVA), BES, paraspinal muscle mass, visual analog scale (VAS) for low back pain, Oswestry Disability Index (ODI), and EuroQoL-5 Dimension (EQ5D) score after adjusting for sex, age, Hospital Anxiety and Depression Scale score, and Charlson Comorbidity Index. In addition, multiple logistic regression analysis was used to investigate the association between BMI and prevalent vertebral fracture, disc degeneration, and Modic changes.

RESULTS

BMI was significantly correlated with SVA, BES, paraspinal muscle mass, VAS, ODI, and EQ5D score. The increase in BMI was associated with the deterioration of all outcomes, which accelerated when the BMI increased from approximately 22-23 kg/m². Moreover, overweight/obesity was significantly correlated with disc degeneration and Modic changes.

CONCLUSION

Increased BMI is significantly associated with spinal pathologies such as SVA, BES, paraspinal muscle mass, VAS, QOL, disc degeneration, and Modic changes. The findings suggest that measures for controlling overweight and obesity among older adults can play an important role in the prevention and treatment of spinal pathologies.

Assessment of Quality of Life Among Patients With Primary Hypothyroidism: A Case-Control Study

Introduction Hypothyroidism is a globally prevalent condition with a huge impact on health. It has been demonstrated that hypothyroidism is associated with negative health outcomes that have a significant impact on quality of life. The aim of this study is to assess the relative significance of various parts of quality of life satisfaction in adult patients with hypothyroidism. This study has never been done in Saudi Arabia. No previous research was conducted in our region to highlight the quality of life of these patients. From this, it is very important to acknowledge the impact of hypothyroidism on quality of life, to help improve their lives and reduce the burden of the disease. Method This is a case-control study conducted on patients with hypothyroidism presented to the family medicine clinic at King Abdulaziz University Hospital. The participants were divided into two groups: patients with primary hypothyroidism (cases) and euthyroid subjects of the same age without chronic illnesses (control group). We used the Short Form-12 questionnaire (SF-12) and a sociodemographic questionnaire as a tool to assess the quality of life. Results Compared to healthy euthyroid controls, patients with hypothyroidism had a significantly reduced quality of life regarding their physical (p<0.001) aspect, with mental health not being affected. Smoking, female gender, and BMI showed significant associations with their mental health status (p=0.021, p=0.001, and p=0.045) respectively. Conclusions Regarding the results of the current study, there is a reduced level of physical health in patients with hypothyroidism than in healthy controls, which adversely affects their QoL. Smoking, gender, and BMI were associated with lower mental health among patients with hypothyroidism, which adversely affected their quality of life. Health practices should include assessment of the quality of life, monitoring by specialized physicians, and educational programs for these patients.

Relationships among changes in physical activity, quality of life, and obesity-Status following a behavioral intervention for rural Appalachian adults

•

Increasing weekly strength training was associated with reduced unhealthy days.

•

No other physical activity and health-related quality of life (HRQoL) changes were linked.

•

Baseline obesity did not moderate physical activity and HRQoL change relationships.

Improved health-related quality of life (HRQoL) is one benefit of physical activity. Yet, there is limited intervention research exploring (1) whether changes in physical activity influence changes in HRQoL among community-based populations and (2) if baseline obesity status influences the relationships. This exploratory analysis used secondary data from rural Appalachian adults who completed the MoveMore arm of a larger randomized control trial (n = 105, M_age = 41.8, 82 % female, 96 % White, M_income= $25,911). Specifically, this study examined associations among changes in physical activity and HRQOL and whether baseline obesity status moderated changes. Three HRQoL variables (self-rated health status, total unhealthy days, days poor health impacted activities) and two physical activity variables [weekly moderate-vigorous physical activity (MVPA) minutes, weekly strength training minutes] were collected at baseline and 6-months. Regression models, adjusted for age, gender, race, income, education, assessed associations between physical activity and HRQoL change variables. Moderation analyses explored the influence of baseline obesity status on these relationships. Participants reported significant improvements in self-rated health status (P = 0.001), weekly MVPA minutes (P = 0.008), and weekly strength training minutes (P < 0.001). Increasing weekly strength training minutes was associated with fewer days poor health impacted activities (B = -0.040, P = 0.013). Weekly minutes of MVPA was not associated with HRQoL variables. Baseline obesity status did not moderate relationships. Findings suggest increasing weekly strength training may reduce days poor health impacted activities and that relationships among changes in physical activity and HRQoL were not impacted by baseline obesity. Findings have implications for promoting strength activities in community-based physical activity interventions for rural populations.

Quality of life among cancer patients at Queen Elizabeth and Kamuzu Central Hospitals in Malawi: a cross-sectional double-center study

Introduction

Many cancer patients experience psychosocial challenges that affect quality of life during the trajectory of their disease process. We aimed at estimating quality of life among cancer patients at two major tertiary hospitals in Malawi.

Methods

The study was conducted among 398 cancer patients using semi-structured questionnaire. Quality of life was measured using EQ-5D-3L instrument.

Results

Mean age was 45 years ± 12.77. Pain (44%) was the most prevalent problem experienced by cancer patients. About 23% had worst imaginable health status on the subjective visual analogues scale. Attending cancer services at QECH (AOR= 0.29, 95% CI: 0.17-0.54, p<0.001) and having normal weight (AOR=0.25, 95% CI: 0.08-0.74, p = 0.012), were associated with improved quality of life. A history of ever taken alcohol (AOR= 2.36, 95% CI: 1.02-5.44, p = 0.045) and multiple disease comorbidities (AOR= 3.78, 95% CI: 1.08-13.12, p = 0.037) were associated with poor quality of life.

Conclusion

Loss of earning, pain, marital strife, sexual dysfunction, were among the common psychosocial challenges experienced. History of ever taken alcohol and multiple comorbidities were associated with poor quality of life. There is need to integrate psychosocial solutions for cancer patients to improve their quality of life and outcomes.

The prototype of a preference-based index of weight-related quality of life: demonstrating the possibilities

PURPOSE

Evidence for comparative and cost-effectiveness of weight-loss interventions is lacking as there are no obesity-specific measures fit for this purpose. This study aimed to estimate the extent to which a prototype of a brief, multi-dimensional obesity-specific Preference-Based Index of Weight-Related Quality of Life (PBI-WRQL) could fill this gap.

METHODS

Longitudinal data from a Canadian bariatric cohort was used. Forty-eight items from the IWQoL-Lite, EQ-5D-3L, and SF-12V2 were mapped onto the WHO ICF domains, and one item was chosen for the dimension based on fit to the Rasch model. Individuals' health ratings (0-100) were regressed on each dimension, and the regression coefficients for the response options were used as weights to generate a total score. Generalized estimation equations were used to compare measure parameters across groups and levels of converging constructs.

RESULTS

Pre-surgery data were available on 201 people (Women: 82%; BMI: 48.8 ± 6.7 kg/m²; age: 43 ± 9.0 years) and on 125 (62%) at 6 months post-bariatric surgery. Seven dimensions with three response options formed the PB-WRQL prototype: Mobility/Physical Function, Pain, Depression, Participation, Energy, Peripheral Edema, and Dyspnea. The prototype showed substantial change (mean + 40) with bariatric surgery, higher than the EQ-5D (mean + 11.5). The prototype showed the strongest relationship with BMI at baseline (t = - 3.68) and was the most sensitive to change in BMI (t = - 3.42).

CONCLUSION

This study demonstrates that a brief, 7-dimension index weighted by health impact performed as well as the 31-item IWQoL-Lite and better than the EQ-5D-3L. These findings demonstrate the potential value of the brief PB-WRQL prototype index and support its further development using preference weights to reflect the current generation's needs and concerns.

Association between weight loss, change in physical activity, and change in quality of life following a corporately sponsored, online weight loss program

Background

The physiological benefits associated with corporately sponsored weight loss programs are increasingly well documented. However, less is known about how these programs affect employees’ quality of life (QoL). The purpose of the present analysis was to examine the association between weight loss, change in physical activity, and change in QoL following a corporately sponsored, online weight loss program.

Methods

We examined the relationship between weight loss, self-reported change in physical activity, and change in several QoL indices in 26,658 participants (79% women) after the initial 10 weeks of the online weight loss program. The trend in changes in each QoL index with increasing weight loss and change in physical activity was examined using logistic regression analysis.

Results

We observed greater improvements in each QoL index with increasing weight loss (p-for-trend, < 0.001) as well as with progressive increases in physical activity (p-for-trend, < 0.001). The combination of increasing weight loss and increases in physical activity were associated with the greatest improvements in each QoL index (additive effect). The percentage of employees reporting improvements in QoL (“improved” or “very much improved”) was 64% for energy, 63% for mood, 33% for sleep, 65% for self-confidence, 68% for indigestion, and 39% for musculoskeletal pain.

Conclusions

Among people, who engage with a commercial weight loss program, greater weight loss during the program was associated with greater improvements in QoL, and increases in physical activity further enhanced the QoL-related benefits.

Racial and weight discrimination associations with pain intensity and pain interference in an ethnically diverse sample of adults with obesity: a baseline analysis of the clustered randomized-controlled clinical trial the goals for eating and moving (GEM) study

BACKGROUND

Everyday experiences with racial (RD) and weight discrimination (WD) are risk factors for chronic pain in ethnically diverse adults with obesity. However, the individual or combined effects of RD and WD on pain in adults with obesity is not well understood. There are gender differences and sexual dimorphisms in nociception and pain, but the effect of gender on relationships between RD, WD, and pain outcomes in ethnically diverse adults with obesity is unclear. Thus, the purposes of this study were to: 1) examine whether RD and WD are associated with pain intensity and interference, and 2) explore gender as a moderator of the associations between RD, WD, and pain.

METHODS

This is a baseline data analysis from a randomized, controlled clinical trial of a lifestyle weight-management intervention. Eligible participants were English or Spanish-speaking (ages 18-69 years) and had either a body mass index of ≥30 kg/m2 or ≥ 25 kg/m2 with weight-related comorbidity. RD and WD were measured using questions derived from the Experiences of Discrimination questionnaire (EOD). Pain interference and intensity were measured using the PROMIS 29 adult profile V2.1. Linear regression models were performed to determine the associations between WD, RD, gender, and pain outcomes.

RESULTS

Participants (n = 483) reported mild pain interference (T-score: 52.65 ± 10.29) and moderate pain intensity (4.23 ± 3.15). RD was more strongly associated with pain interference in women (b = .47, SE = .08, p < 001), compared to men (b = .14, SE = .07, p = .06). Also, there were no significant interaction effects between RD and gender on pain intensity, or between WD and gender on pain interference or pain intensity.

CONCLUSIONS

Pain is highly prevalent in adults with obesity, and is impacted by the frequencies of experiences with RD and WD. Further, discrimination against adults with obesity and chronic pain could exacerbate existing racial disparities in pain and weight management. Asking ethnically diverse adults with obesity about their pain and their experiences of RD and WD could help clinicians make culturally informed assessment and intervention decisions that address barriers to pain relief and weight loss.

A web-based intervention is feasible for supporting weight loss and increased activity in rural women with arthritis

Rural women have well documented health disparities, with higher prevalence of obesity and chronic conditions, including arthritis. Change in weight and actigraph-recorded data were examined in a subset of 63 of 82 women with physician-diagnosed arthritis who completed a 30-month web-based clinical trial. Repeated measures analyses showed women lost weight from baseline to six months, slowly regained at 18 and 30 months, ending with a lower weight than baseline F(1,62)=40.89, p<0.001, η2p =0.40. Of 53 women with complete data, activity increased at six months, decreased at 18 months, and increased at 30 months F(1,52)=4.14, p =.04, η2p=0.07. Women showed improved change in weight and activity from baseline at six, 18 and 30 months. This study adds support that web-based programs may promote weight loss and activity in a hard-to-reach, underserved population of midlife and older rural women with arthritis.

The Norwegian PROMIS-29: psychometric validation in the general population for Norway

Background

The Patient Reported Outcome Measurement Information System profile instruments include “high information” items drawn from large item banks following the application of modern psychometric criteria. The shortest adult profile, PROMIS-29, looks set to replace existing short-form instruments in research and clinical practice. The objective of this study was to undertake the first psychometric evaluation of the Norwegian PROMIS-29, following a postal survey of a random sample of 12,790 Norwegians identified through the National Registry of the Norwegian Tax Administration. Confirmatory factor analysis was used to assess structural validity. Fit to the Rasch partial credit model and differential item functioning (DIF) were assessed in relation to age, gender, and education. PROMIS-29 scores were compared to those for the EQ-5D-5L and the Self-assessed Comorbidity Questionnaire (SCQ), for purposes of assessing validity based on a priori hypotheses.

Results

There were 3200 (25.9%) respondents with a mean age (SD) of 51 (20.7, range 18 to 97 years) and 55% were female. The PROMIS-29 showed satisfactory structural validity and acceptable fit to Rasch model including unidimensionality, and measurement invariance across age and education levels. One pain interference item had uniform DIF for gender but splitting gave satisfactory fit. Domain reliability estimates ranged from 0.85 to 0.95. Correlations between PROMIS-29 domain, SCQ and EQ-5D scores were largely as expected, the largest being for scores assessing very similar aspects of health.

Conclusions

The Norwegian version of the PROMIS-29 is a reliable and valid generic self-reported measure of health in the Norwegian general population. The instrument is recommended for further application, but the analysis should be replicated and responsiveness to change assessed in future studies before it can be recommended for clinical and health services evaluation in Norway.

A Mobile Health Behavior Intervention to Reduce Pain and Improve Health in Older Adults With Obesity and Chronic Pain: The MORPH Pilot Trial

Chronic, multisite pain is a common phenomenon in aging and is associated with a host of negative health outcomes. It is a complex and multifaceted condition that may be exacerbated by weight gain and long periods of inactivity. Unfortunately, older adults suffering from chronic pain have unique barriers limiting access to center-based behavior change interventions. The MORPH study first adapted and iteratively refined an evidence-based group-mediated intervention for delivery in the home via mHealth tools (a smartphone app, teleconferencing software, wearable activity monitor, smart weight scale). This was followed by a pilot randomized controlled trial (RCT) meant to assess feasibility of the MORPH intervention, and to examine initial effects on physical function, pain, weight, and sedentary behavior. We recruited low-active and obese older adults with multisite pain to partake in a series of N-of-1 refinement studies (N = 5 total) or a 12-week pilot RCT delivered largely in the home (N = 28 assigned to active intervention or wait-list control). The refinement phase identified several key technological (e.g., selection of a new smart weight scale) and user interface (e.g., clarification of in-app phrasing) modifications that were made before initiating the RCT phase. Analyses of covariance, controlling for baseline values, sex, and age indicated effects favoring the intervention across all domains of interest: there was a substantially clinically meaningful difference in short physical performance battery scores (0.63 points, η² = 0.08), a moderate-to-large difference in PROMIS pain intensity scores (5.52 points, η² = 0.12), a large difference in body weight (2.90 kg, η² = 0.207), and a moderate effect on adjusted ActivPAL-assessed sedentary time (64.90 min, η² = 0.07) with a small effect on steps (297.7 steps, η² = 0.01). These results suggest a largely-home delivered movement and weight loss program for older adults with pain is feasible and recommendations are provided for future programs of this nature.

Poor Sleep Quality Decreases Concurrent Training Benefits in Markers of Metabolic Syndrome and Quality of Life of Morbidly Obese Patients

Background: Sleep quality (SQ) plays a role in multiple activities of daily living, but little is known about its role in concurrent training [CT, high-intensity interval (HIIT) plus resistance training (RT)] adaptations for metabolic syndrome (MetS) and health-related quality of life (HRQoL) markers. The aim of the present study was to determine the effects of a 20-week CT programme on MetS and HRQoL markers according to the SQ of morbidly obese patients. Methods: Twenty-nine morbidly obese patients were allocated to one of two groups: good sleep quality (GSQ, n = 15, 38.07 ± 12.26 years) and poor sleep quality (PSQ, n = 14, 40.79 ± 11.62 years). HRQoL, body mass index, waist circumference (WC), systolic and diastolic blood pressure (SBP and DBP, respectively), and plasma outcomes were measured. Results: The GSQ group reported significant changes (pre- vs. post-intervention) in WC (114.0 ± 3.1 vs. 110.4 ± 3.4 cm, p = 0.012), SBP (137.0 ± 4.3 vs. 125.6 ± 1.8 mmHg, p = 0.006), and HRQoL general health (51.33 ± 21.08 vs. 64.33 ± 16.24, p = 0.020). By contrast, the PSQ group showed significant changes only in SQ (9.00 ± 2.42 vs. 5.36 ± 2.84, p = 0.004). Conclusions: Morbidly obese PSQ patients showed a lower response for improving MetS and HRQoL markers after a 20-week CT programme than GSQ peers. However, there was a greater effect size for decreasing WC and SBP in favour of the GSQ compared with the PSQ group, suggesting that there are limitations to CT benefits on these outcomes in the PSQ group. These results call for more complex future studies.
