Abstract
The obesity epidemic is a growing concern in the United States. Aside from the detrimental health effects of obesity, previous work has also documented a negative relationship between obesity and various labor market outcomes. Given that the American adult obesity rate is roughly 40%, obesity affects a large portion of the US labor market. In this study, I analyze the impact of obesity on income and employment over business cycle fluctuations. I find that during economic downturns, obese workers experience larger declines in income and employment relative to their healthy weight peers. These effects exist for both genders and are concentrated amongst younger adults.

Abstract
Background: Presenteeism is an emerging work-related health problem among train drivers. It is more serious than absenteeism, as it accounts for higher productivity losses over the long term and may increase the risk of occupational accidents. Train drivers have high rates of mental and physical health conditions that may put them at high risk of presenteeism. Methods: A comparative cross-sectional study was conducted on 100 train drivers working in Mansoura railway station and 100 administrative employees working in the Faculty of Medicine, Mansoura university as a comparison group to estimate the prevalence of presenteeism and its associated factors among train drivers working in Mansoura railway station, Egypt. A questionnaire was used to collect socio-demographic, occupational and medical data. The Kessler Psychological Distress Scale (K10) was used to measure non-specific psychological distress. The Stanford Presenteeism Scale (SPS-6) was used to assess productivity loss related to sickness presenteeism. Results: The prevalence of presenteeism was significantly higher among train drivers (76%) compared to the comparison group (31%). All participants (100%) with psychological distress reported presenteeism. Being a train driver (adjusted odds ratio [AOR]=5.4) and having hypertension (AOR=4.03) are independent predictors for presenteeism. Conclusions: The prevalence of presenteeism and its associated risk factors were significantly higher among train drivers than the comparison group. There is an urgent need for the railway industry to understand the factors that may contribute to presenteeism.

Relationships between enabling services use and access to care among adults with cardiometabolic risk factors: findings from the 2014 National Health Center Patient Survey. BMC Health Serv Res 2022; 22:334. [PMID: 35287668 PMCID: PMC8922912 DOI: 10.1186/s12913-022-07739-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2021] [Accepted: 03/03/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Community health centers (CHCs) provide comprehensive primary and preventive care to medically underserved, low-income, and racially/ethnically diverse populations. CHCs also offer enabling services, non-clinical assistance to reduce barriers to healthcare due to unmet social and material needs, to improve access to healthcare and reduce health disparities. For patients with modifiable cardiometabolic risk factors, including obesity, hypertension, and diabetes, enabling services may provide additional support to improve disease management. However, little is known about the relationship between enabling services and healthcare accessibility and utilization among patients with cardiometabolic risk factors. METHODS This study uses data from the 2014 Health Center Patient Survey to examine the relationship between enabling services use and delayed/foregone care, routine check-ups, and emergency room visits, among adult community health center patients in the United States with cardiometabolic risk factors (N = 2358). Outcomes of enabling services users were compared to nonusers using doubly robust propensity score matching methods and generalized linear regression models. RESULTS Overall, enabling service users were 15.4 percentage points less likely to report delayed/foregone care and 29.4 percentage points more likely to report routine check-ups than nonusers. Enabling service users who lived in urban areas, younger and middle-aged adults, and those with two cardiometabolic risk factors were also less likely to report delayed/foregone care and/or more likely to report routine check-ups in comparison with nonusers. However, among adults with three or more cardiometabolic risk factors, enabling services use was associated with a 41.3 percentage point increase in emergency room visits and a 7.6 percentage point decrease in routine check-ups. CONCLUSIONS The findings highlight the value in utilizing enabling services to improve timeliness and receipt of care among CHC patients with heightened cardiometabolic risk. There is a need for targeting high-risk populations with additional enabling services to support management of multiple chronic conditions.

Abstract
Obesity is associated with changes in memory. Thus, the aim of this systematic review was to investigate the physical exercise consequences on memory in obesity. A search was carried out in the PubMed, Lilacs, and Scielo databases with the following descriptors: "physical exercise," "memory," and "obesity." A total of 16 studies were analyzed in this review. Low, moderate, and high intensity exercise training showed positive effects on memory in patients with obesity (100%). The animal models of obesity used in their physical exercise protocols: treadmill (72.7%) or wheel running (27.3%). Most of the animal studies (81.8%) revealed positive effects of the physical exercise protocol on memory in obesity. Mouse was the most commonly used animal (54.5%), and a 60% high-fat diet (HFD) was the most commonly method used to induce obesity (82%). We did not identify any knockout model of obesity that was used to evaluate memory and used physical exercise as the main intervention. Thus, exercise training, independently if it is resistance or endurance training, seems to be an excellent intervention to prevent and inhibit cognitive impairment and memory loss on obese patients and animal models of obesity.

Abstract
The prevalence and factors that influence prehypertension and hypertension in workers at elderly welfare facilities remain unknown. This study investigated prehypertension and hypertension as well as the relevant factors affecting the development of these conditions in workers at elderly welfare facilities.A cross-sectional survey was conducted among 242 workers at 3 elderly welfare facilities in northern Taiwan. A structured questionnaire survey comprising demographic characteristics, job characteristics, burnout inventory, and health information was employed for data collection. Chi-Squared tests and multinomial logistic regression were adopted to analyze the correlation between research variables and blood pressures as well as relevant factors influencing prehypertension and hypertension.The results indicated that sex, age, education level, type of work shift, work-related burnout, and body mass index of the research participants were significantly correlated with prehypertension and hypertension. The results of multinominal logistic regression demonstrated that being male, being older, being a nonnurse assistant, being obese, working in shifts, and having moderate or severe work-related burnout were associated with higher risks of prehypertension and hypertension. The interaction between age and being a nonnurse assistant was statistically significant. Compared with nonnurse assistants, nurse assistants aged ≥55 years had a relatively low risk of prehypertension and hypertension.Age, job characteristics, work-related burnout, and obesity of workers in elderly welfare facilities were the major risk factors for prehypertension and hypertension.

Abstract
Alzheimer's disease (AD) and type 2 diabetes (T2D) major feature is insulin resistance. Brain and peripheral insulin resistance lead to hyperglycemia, which contributes to the development of T2D-linked comorbidities, such as obesity and dyslipidemia. Individuals with hyperglycemia in AD present with neuronal loss, formation of plaques and tangles and reduced neurogenesis. Inflammation seems to play an essential role in the development of insulin resistance in AD and T2D. We conducted a literature review about the links between AD and T2D. Alterations in glucose metabolism result from changes in the expression of the insulin receptor substrates 1 and 2 (IRS-1 and IRS-2), and seem to be mediated by several inflammatory pathways being present in both pathologies. Although there are some similarities in the insulin resistance of AD and T2D, brain and peripheral insulin resistance also have their discrete features. Failure to activate IRS-1 is the hallmark of AD, while inhibition of IRS-2 is the main feature in T2D. Inflammation mediates the alterations in glucose metabolism in AD and T2D. Targeting inflammation and insulin receptors may be a successful strategy to prevent and ameliorate T2D and AD symptoms.

Abstract
PURPOSE There are known associations between cardiometabolic risk factors and polypharmacy; however, there is no evidence about how polypharmacy among adults with cardiometabolic risk factors impacts their health-related quality of life (HRQoL). The main objective of this study was to assess the association between polypharmacy and HRQoL among adults with cardiometabolic risk factors living in the USA. METHODS Individuals age ≥ 18 years with at least one of the three cardiometabolic risk factors (diabetes, hyperlipidemia, and hypertension) were identified from the Medical Expenditure Panel Survey 2015 data. We defined polypharmacy as use of at least five classes of prescription medications. Physical component summary (PCS) and mental component summary (MCS) were obtained from the 12-item Short-Form Health Survey version 2 to measure HRQoL. We conducted adjusted ordinary least-square regressions to determine the association between polypharmacy and HRQoL. RESULTS We identified 7621 (weighted N = 80 million) adults with at least one cardiometabolic risk factors of whom 46.9% reported polypharmacy. Polypharmacy was noted in 29.7% of those with hypertension, whereas 82.4% of those with all the three cardiometabolic risk factors had polypharmacy. The unadjusted mean PCS and MCS scores for those with polypharmacy were lower than those without polypharmacy. In the multivariable regressions, we found that adults with polypharmacy had significantly lower PCS scores (β = - 4.27, p < 0.0001) compared to those without polypharmacy, while the MCS scores between those with and without polypharmacy were no longer significantly different. CONCLUSION Surveillance of use of concurrent prescription medications is warranted so as to improve physical functioning in this vulnerable group.

Abstract
Aims: This analysis evaluated the cost-effectiveness of once-weekly semaglutide vs glucagon-like peptide-1 receptor agonists (GLP-1 RAs) in patients with type 2 diabetes (T2D) uncontrolled on metformin or basal insulin in Sweden. Materials and methods: This cost-effectiveness analysis (CEA) was conducted using the Swedish Institute of Health Economics (IHE) Diabetes Cohort Model. Analyses were conducted from the Swedish societal perspective over a time horizon of 40 years. For patients uncontrolled on metformin, dulaglutide was the comparator, and data from the SUSTAIN 7 clinical trial was used. For patients uncontrolled on basal insulin, lixisenatide was chosen as the comparator and data was obtained from a network meta-analysis (NMA). Results: The results show that, in patients with inadequate control on metformin, semaglutide 1.0 mg dominated (i.e. provided greater clinical benefit, and was less costly) dulaglutide 1.5 mg. In patients with inadequate control on basal insulin, semaglutide 1.0 mg dominated lixisenatide. The reduction in costs is largely driven by the reduction in complications seen with once-weekly semaglutide. Limitations and conclusions: It is likely that this analysis is conservative in estimating the cardiovascular (CV) cost benefits associated with treatment with once-weekly semaglutide. In patients inadequately controlled on basal insulin, the analyses vs lixisenatide were based on results from an NMA, as no head-to-head clinical trial has been conducted for this comparison. These CEA results show that once-weekly semaglutide is a cost-effective GLP-1 RA therapy for the treatment of T2D in patients inadequately controlled on metformin or basal insulin, addressing many current clinician, patient, and payer unmet needs in Sweden.

Abstract
BACKGROUND In the USA, three types of bariatric surgeries are widely performed, including laparoscopic sleeve gastrectomy (LSG), laparoscopic Roux-en-Y gastric bypass (LRYGB), and laparoscopic adjustable gastric banding (LAGB). However, few economic evaluations of bariatric surgery are published. There is also scarcity of studies focusing on the LSG alone. Therefore, this study is evaluating the cost-effectiveness of bariatric surgery using LRYGB, LAGB, and LSG as treatment for morbid obesity. METHODS A microsimulation model was developed over a lifetime horizon to simulate weight change, health consequences, and costs of bariatric surgery for morbid obesity. US health care prospective was used. A model was propagated based on a report from the first report of the American College of Surgeons. Incremental cost-effectiveness ratios (ICERs) in terms of cost per quality-adjusted life-year (QALY) gained were used in the model. Model parameters were estimated from publicly available databases and published literature. RESULTS LRYGB was cost-effective with higher QALYs (17.07) and cost ($138,632) than LSG (16.56 QALYs; $138,925), LAGB (16.10 QALYs; $135,923), and no surgery (15.17 QALYs; $128,284). Sensitivity analysis showed initial cost of surgery and weight regain assumption were very sensitive to the variation in overall model parameters. Across patient groups, LRYGB remained the optimal bariatric technique, except that with morbid obesity 1 (BMI 35-39.9 kg/m2) patients, LSG was the optimal choice. CONCLUSION LRYGB is the optimal bariatric technique, being the most cost-effective compared to LSG, LAGB, and no surgery options for most subgroups. However, LSG was the most cost-effective choice when initial BMI ranged between 35 and 39.9 kg/m2.

Abstract
Objective: The aim of this study was to quantify the relationship between workers’ body mass index and work productivity within various occupations. Methods: Data from two administrations (2014 and 2015) of the United States (US) National Health and Wellness Survey, an Internet-based survey administered to an adult sample of the US population, were used for this study (n = 59,772). Occupation was based on the US Department of Labor's 2010 Standardized Occupation Codes. Outcomes included work productivity impairment and indirect costs of missed work time. Results: Obesity had the greatest impact on work productivity in Construction, followed by Arts and Hospitality occupations. Outcomes varied across occupations; multivariable analyses found significant differences in work productivity impairment and indirect costs between normal weight and at least one obesity class. Conclusion: Obesity differentially impacted productivity and costs, depending upon occupation.

Abstract
BACKGROUND The combined associations of body mass index (BMI) levels and metabolic dysfunction with medical and dental care utilizations is unclear. METHODS A 4-year follow-up study was performed in 16,386 Japanese male employees (mean age 48.2 [standard deviation, 11.0] years) without a history of cardiovascular disease (CVD), cancer, or renal failure. They were classified into eight phenotypes based on four BMI levels (underweight, <18.5; normal weight, 18.5-24.9; overweight, 25.0-29.9; and obese, ≥30.0 kg/m2) and the presence or absence of ≥2 of 4 metabolic abnormalities: high blood pressure, high triglycerides, low high-density-lipoprotein cholesterol, and high blood sugar. Based on their health insurance claims data, we compared medical and dental care days and costs among the eight different BMI/metabolic phenotypes during 2010-2013. RESULTS The combinations of BMI levels and metabolic status were significantly associated with the adjusted mean and median medical outpatient days and costs and the median dental outpatient days and costs. The obese/unhealthy subjects had the highest medical outpatient days and costs, and the underweight/unhealthy subjects had the highest dental outpatient days and costs. The underweight/unhealthy subjects also had the highest medical inpatient days and hospitalization rates of CVD, and had higher medical costs compared with the obese/healthy subjects. The differences in median medical costs between healthy and unhealthy phenotypes were larger year by year across all BMI levels. CONCLUSIONS Identification of obesity phenotypes using both BMI levels (including the underweight level) and metabolic status may more precisely predict healthcare days and costs compared with either BMI or metabolic status alone.

Abstract
OBJECTIVE This study aimed to estimate treatment costs attributable to overweight and obesity in patients with diabetes who were less than 65 years of age in the United States. METHODS This study used data from the Medical Expenditure Panel Survey from 2001 to 2013. Patients with diabetes were identified by using the International Classification of Diseases, Ninth Revision, Clinical Modification code (250), clinical classification codes (049 and 050), or self-reported physician diagnoses. Total treatment costs attributable to overweight and obesity were calculated as the differences in the adjusted costs compared with individuals with diabetes and normal weight. Adjusted costs were estimated by using generalized linear models or unconditional quantile regression models. RESULTS The mean annual treatment costs attributable to obesity were $1,852 higher than those attributable to normal weight, while costs attributable to overweight were $133 higher. The unconditional quantile regression results indicated that the impact of obesity on total treatment costs gradually became more significant as treatment costs approached the upper quantile. CONCLUSIONS Among patients with diabetes who were less than 65 years of age, patients with diabetes and obesity have significantly higher treatment costs than patients with diabetes and normal weight. The economic burden of diabetes to society will continue to increase unless more proactive preventive measures are taken to effectively treat patients with overweight or obesity.

Abstract
OBJECTIVE The increasingly high levels of overweight and obesity among the workforce are accompanied by a hidden cost burden due to losses in productivity. This study reviews the extent of indirect cost of overweight and obesity. METHODS A systematic search was conducted in eight electronic databases (PubMed, Cochrane Library, Web of Science Core Collection, PsychInfo, Cinahl, EconLit and ClinicalTrial.gov). Additional studies were added from reference lists of original studies and reviews. Studies were eligible if they were published between January 2000 and June 2017 and included monetary estimates of indirect costs of overweight and obesity. The authors reviewed studies independently and assessed their quality. RESULTS Of the 3626 search results, 50 studies met the inclusion criteria. A narrative synthesis of the reviewed studies revealed substantial costs due to lost productivity among workers with obesity. Especially absenteeism and presenteeism contribute to high indirect costs. However, the methodologies and results vary greatly, especially regarding the cost of overweight, which was even associated with lower indirect costs than normal weight in three studies. CONCLUSION The evidence predominantly confirms substantial short-term and long-term indirect costs of overweight and obesity in the absence of effective customised prevention programmes and thus demonstrates the extent of the burden of obesity beyond the healthcare sector.

Abstract
PURPOSE OF REVIEW The objective was to review prevention efforts and approaches attempting to limit the problem of obesity in the military. RECENT FINDINGS Various individual-level initiatives have emerged, including programs promoting healthy cooking, meal planning, and other behavior changes among service members. Importantly, the military is attempting to tackle environmental factors contributing to the rise of obesity, by focusing on many recent environmental-level interventions and initiatives to improve military dining facilities and examine and modify other aspects of installations' built environments. Although published research within the military setting directed towards obesity prevention is limited, many innovative programs have been launched and need to be followed forward. The review of past and ongoing efforts can be an important step in identifying specific areas needing improvement, gaps that should be considered, lessons learned, and characteristics of successful programs that should be disseminated as best practices and further expanded.

Abstract
PURPOSE To estimate annual health care and productivity loss costs attributable to overweight or obesity in working asthmatic patients. MATERIALS AND METHODS This study was conducted using the 2003-2013 Medical Expenditure Panel Survey (MEPS) in the United States. Patients aged 18 to 64 years with asthma were identified via self-reported diagnosis, a Clinical Classification Code of 128, or a ICD-9-CM code of 493.xx. All-cause health care costs were estimated using a generalized linear model with a log function and a gamma distribution. Productivity loss costs were estimated in relation to hourly wages and missed work days, and a two-part model was used to adjust for patients with zero costs. To estimate the costs attributable to overweight or obesity in asthma patients, costs were estimated by the recycled prediction method. RESULTS Among 11670 working patients with a diagnosis of asthma, 4428 (35.2%) were obese and 3761 (33.0%) were overweight. The health care costs attributable to obesity and overweight in working asthma patients were estimated to be $878 [95% confidence interval (CI): $861-$895] and $257 (95% CI: $251-$262) per person per year, respectively, from 2003 to 2013. The productivity loss costs attributable to obesity and overweight among working asthma patients were $256 (95% CI: $253-$260) and $26 (95% CI: $26-$27) per person per year, respectively. CONCLUSION Health care and productivity loss costs attributable to overweight and obesity in asthma patients are substantial. This study's results highlight the importance of effective public health and educational initiatives targeted at reducing overweight and obesity among patients with asthma, which may help lower the economic burden of asthma.

Abstract
OBJECTIVE Estimate the economic burden associated with incremental increases in the number of cardiometabolic risk factors (CMRFs) in the US. METHODS We used the nationally representative Medical Expenditure Panel Survey from 2010 to 2012 to create a retrospective cohort of people based on the number of CMRFs (one, two, and three or four), and a comparison cohort of people with zero CMRFs. CMRFs included abdominal obesity, elevated blood pressure, elevated triglycerides, and elevated glucose and were defined using diagnostic codes, prescribed medications, and survey responses. Adjusted regression analysis was developed to compare health expenditures, utilization, and lost-productivity differences between the cohorts. Generalized linear regression was used for health care expenditures, and negative binomial regression was used for utilization and productivity, controlling for individual characteristics. RESULTS The number of CMRFs was associated with significantly more annual utilization, health care expenditures, and reduced productivity. As compared with people with zero CMRFs, people with one, two, and three or four CMRFs had 1.15 (95% confidence interval [CI]: 1.06, 1.24), 1.37 (95% CI: 1.25, 1.51), and 1.39 (95% CI: 1.22, 1.57) times higher expected rate of emergency room visits, respectively. Compared with people with zero CMRFs, people with one, two, and three or four CMRFs had increased incremental health care expenditures of US$417 (95% CI: $70, $763), US$2,326 (95% CI: $1,864, $2,788), and US$4,117 (95% CI: $3,428, $4,807), respectively. Those with three or four CMRFs reported employment of 60%, compared with 80% in patients with zero CMRFs. People with three or four CMFRs had 1.75 (95% CI: 1.42, 2.17) times higher expected rate of days missed at work due to illness, compared with people with zero CMRFs. CONCLUSION Our findings demonstrate a direct association between economic burden and number of CMRFs. Although this was expected, the increase in burden that was independent from the cost of cardiovascular disease was surprising.

Abstract
OBJECTIVE To evaluate the health-related quality of life (HRQOL) of patients with diabetes and persons at high risk of developing diabetes and the association between HRQOL scores and subsequent medical expenditures in these persons. METHODS Data came from the Medical Expenditure Panel Survey. Body mass index (BMI) and hypertension were used to identify risk of diabetes. Burden was assessed by comparing SF-12 physical (PCS) and mental (MCS) summary scores in patients with diabetes and those at risk of having diabetes to the age- and gender-adjusted PCS and MCS of those with normal BMI and no hypertension. Associations between PCS and MCS and medical expenditures were modeled using a two-part model that controlled for clinical and demographic factors. Percent increase in expenditure associated with PCS and MCS differences was evaluated as the ratio of estimated expenditure, holding other factors fixed. RESULTS Diabetes risk factors were associated with up to 9-point lower PCS and 3-point lower MCS score. Overall, 1-, 2-, 5-, and 10-point lower PCS scores were associated with 2.9%, 5.8%, 15.0%, and 31.8% higher expenditures, and lower MCS scores were associated with 1.3%, 2.6%, 6.5%, and 13.5% higher expenditures, respectively. CONCLUSIONS The reported associations can help clinicians and researchers interpret the magnitude of HRQOL score differences.

Abstract
The authors estimated the lost productive time (LPT) due to absenteeism and presenteeism among employees at the Group Health Cooperative with controlled and uncontrolled hypertension compared with normotensive patients. The patients responded to a survey inquiring about health behaviors with links to their medical record to identify diagnoses, blood pressure measurement, and prescription drug dispenses. Individuals with controlled hypertension were more likely to report any LPT relative to individuals with uncontrolled hypertension (40.6% vs 32.6%, P<.05). There were no significant differences in the average hours of LPT due to presenteeism among individuals regardless of their hypertension status but individuals with hypertension were more likely to report hours of LPT due to absenteeism compared with normotensive individuals (1.04 vs 0.59 hours; P=.001). Individuals with uncontrolled hypertension were more likely to report LPT due to absenteeism compared with individuals with controlled hypertension (1.35 vs 0.72 hours; P=.001). There were no significant differences between individuals with hypertension whose blood pressure was controlled and normotensive individuals with respect to the likelihood of reporting any LPT or in the amounts of absenteeism and presenteeism.

Abstract
This study aimed to examine the association between obstructive sleep apnea (OSA) and obesity among young adults. A total of 2911 college students in Thailand participated in the study. Anthropometric measurements and blood pressure were taken by trained research staff. Overall, 6.3% of college students had OSA determined by the Berlin Questionnaire, 9.6% were overweight (BMI: 25-29 kg/m2), 4.5% were obese (BMI≥30 kg/m2); 12.4% had abdominal obesity (men: waist circumference≥90 cm; women: waist circumference≥80 cm). There were significant associations between OSA and overweight (odds ratio (OR)=1.72; 95% confidence interval (CI)=1.04-1.85) and obesity (OR=24.23; 95% CI=15.20-38.61), independent of demographic and lifestyle factors, blood pressure, and psychological distress. Students with OSA were more likely to have abdominal obesity than those without OSA (OR=2.09; 95% CI=1.19-3.67). OSA was significantly related to joint effects of general and abdominal obesity. The OSA-obesity associations were robust and evident for both genders, individuals with normal and elevated blood pressure, and those with and without psychological distress. This study shows independent associations of OSA with general and abdominal obesity among young adults. OSA could be a risk factor for obesity and consequent cardiovascular morbidities. OSA screening and treatment might be important for young adults.

Abstract
The main objective of this study was to provide cost estimates of human Escherichia coli O157 infection to facilitate future assessment of the benefits and costs of alternative preventive strategies to reduce illness. We investigated the costs of illness to Canadians from primary human infection by verotoxigenic E. coli O157 (also called Shiga toxin-producing E. coli O157) using data from the National Notifiable Diseases Registry. We used relative risk information from peer-reviewed publications to estimate the burden of illness and associated costs for eight long-term health outcomes. National estimates of the number of cases (mean and 5th and 95th percentiles), associated costs, and a rank correlation test to identify which outcomes were associated with the highest per capita costs were calculated. An estimated 22,344 cases of primary infections occur in Canada annually, costing $26.7 million. There are 37,867 additional on-going long-term health outcomes costing $377.2 million each year. Our analysis indicated that the annual cost for primary and long-term illness is $403.9 million. The analysis supports evaluation of alternative control and prevention measures and the development and implementation of policy and practices aimed at safe food production.

Abstract
OBJECTIVE To inform policymakers of the importance of evaluating various methods for estimating the direct medical expenditures for a low-incidence condition, head and neck cancer (HNC). METHODS Four methods of estimation have been identified: 1) summing all health care expenditures, 2) estimating disease-specific expenditures consistent with an attribution approach, 3) estimating disease-specific expenditures by matching, and 4) estimating disease-specific expenditures by using a regression-based approach. A literature review of studies (2005-2012) that used the Medical Expenditure Panel Survey (MEPS) was undertaken to establish the most popular expenditure estimation methods. These methods were then applied to a sample of 120 respondents with HNC, derived from pooled data (2003-2008). RESULTS The literature review shows that varying expenditure estimation methods have been used with MEPS but no study compared and contrasted all four methods. Our estimates are reflective of the national treated prevalence of HNC. The upper-bound estimate of annual direct medical expenditures of adult respondents with HNC between 2003 and 2008 was $3.18 billion (in 2008 dollars). Comparable estimates arising from methods focusing on disease-specific and incremental expenditures were all lower in magnitude. Attribution yielded annual expenditures of $1.41 billion, matching method of $1.56 billion, and regression method of $1.09 billion. CONCLUSIONS This research demonstrates that variation exists across and within expenditure estimation methods applied to MEPS data. Despite concerns regarding aspects of reliability and consistency, reporting a combination of the four methods offers a degree of transparency and validity to estimating the likely range of annual direct medical expenditures of a condition.

Abstract
In response to rising health care costs associated with obesity rates, some health care insurers are adopting incentivized technology-enhanced wellness programs. The purpose of this study is to evaluate the large-scale implementation of an incentivized Internet-mediated walking program for obese adults and to examine program acceptance, adherence, and impact. A mixed-methods evaluation was conducted to investigate program implementation, acceptance, and adherence rates, and physical activity rates among program participants. Program implementation was shaped by national and state policies, data security concerns, and challenges related to incentivizing participation. Among 15,397 eligible individuals, 6,548 (43 %) elected to participate in the walking program, achieving an average of 6,523 steps/day (SD 2,610 steps). Participants who uploaded step counts for 75 % of days for a full year (n = 2,885) achieved an average of 7,500 steps (SD 3,093). Acceptance and participation rates in this incentivized Internet-mediated walking program suggest that such interventions hold promise for engaging obese adults in physical activity.

Abstract
OBJECTIVE To compare the effectiveness of self-management, dietary, physical activity, and/or environmental strategies for the prevention of weight gain among adults in work and college settings. METHOD We conducted a systematic review of work/college-based studies that intervened on adults using one or more of the above strategies with follow up over at least a 12-month period. We excluded studies with a weight loss component. Our weight outcomes included body mass index (BMI), weight, and waist circumference. RESULTS We included 7 work- and 2 college-based interventional studies, which all used combinations of different strategies. There was moderate strength of evidence that work/college-based combination interventions prevented weight gain of ≥0.5kg over 12months as compared to control; however, we were unable to perform meta-analysis due to substantial heterogeneity in the intervention strategies and study populations. These programs did not prevent BMI gain or waist circumference increase. CONCLUSION While we found limited evidence that work/college-based interventions employing a combination of strategies prevent adult weight gain, the combination of personalized diet and physical activity counseling for the individual along with the promotion of healthy lifestyle changes in the environment may be a promising strategy to explore in future research.

Abstract
OBJECTIVES The endoplasmic reticulum (ER) chaperone tauroursodeoxycholic acid (TUDCA) has exhibited promises in the treatment of obesity, although its impact on obesity-induced cardiac dysfunction is unknown. This study examined the effect of TUDCA on cardiomyocyte function in high-fat diet-induced obesity. METHODS Adult mice were fed low or high fat diet for 5 months prior to treatment of TUDCA (300 mg/kg. i.p., for 15d). Intraperitoneal glucose tolerance test (IPGTT), cardiomyocyte mechanical and intracellular Ca(2+) property, insulin signaling molecules including IRS-1, Akt, AMPK, ACC, GSK-3β, c-Jun, ERK and c-Jun N terminal kinase (JNK) as well as ER stress and intracellular Ca(2+) regulatory proteins were examined. Myocardial ultrastructure was evaluated using transmission electron microscopy (TEM). RESULTS High-fat diet depressed peak shortening (PS) and maximal velocity of shortening/relengthenin as well as prolonged relengthening duration. TUDCA reversed or overtly ameliorated high fat diet-induced cardiomyocyte dysfunction including prolongation in relengthening. TUDCA alleviated high-fat diet-induced decrease in SERCA2a and phosphorylation of phospholamban, increase in ER stress (GRP78/BiP, CHOP, phosphorylation of PERK, IRE1α and eIF2α), ultrastructural changes and mitochondrial permeation pore opening. High-fat diet feeding inhibited phosphorylation of AMPK and promoted phosphorylation of GSK-3β. TUDCA prevented high fat-induced dephosphorylation of AMPK but not GSK-3β. High fat diet promoted phosphorylation of IRS-1 (Ser(307)), JNK, and ERK without affecting c-Jun phosphorylation, the effect of which with the exception of ERK phosphorylation was attenuated by TUDCA. CONCLUSIONS These data depict that TUDCA may ameliorate high fat diet feeding-induced cardiomyocyte contractile and intracellular Ca(2+) defects through mechanisms associated with mitochondrial integrity, AMPK, JNK and IRS-1 serine phosphorylation.

Abstract
OBJECTIVES To compare real-world outcomes of initiating insulin glargine (GLA) versus neutral protamine Hagedorn (NPH) insulin among employees with type 2 diabetes mellitus (T2DM) who had both employer-sponsored health insurance and short-tem-disability coverages. DESIGN Retrospective cohort study. SETTING MarketScan Commercial Claims and Encounters/Health and Productivity Management Databases 2003-2009. PARTICIPANTS Adult employees with T2DM who were previously treated with oral antidiabetic drugs and/or glucagon-like-peptide 1 receptor agonists and initiated GLA or NPH were included if they were continuously enrolled in healthcare and short-term-disability coverages for 3 months before (baseline) and 1 year after (follow-up) initiation. Treatment selection bias was addressed by 2:1 propensity score matching. Sensitivity analyses were conducted using different matching ratios. PRIMARY AND SECONDARY OUTCOME MEASURES Outcomes during 1-year follow-up were measured and compared: insulin treatment persistence and adherence; hypoglycaemia rates and daily average consumption of insulin; total and diabetes-specific healthcare resource utilisation and costs and loss in productivity, as measured by short-term disability, and the associated costs. RESULTS A total of 534 patients were matched and analysed (GLA: 356; NPH 178) with no significant differences in baseline characteristics. GLA patients were more persistent and adherent (both p<0.05), had lower rates of hospitalisation (23% vs 31.4%; p=0.036) and endocrinologist visits (19.1% vs 26.9%; p=0.038), similar hypoglycaemia rates (both 4.4%; p=1.0), higher diabetes drug costs ($2031 vs $1522; p<0.001), but similar total healthcare costs ($14 550 vs $16 093; p=0.448) and total diabetes-related healthcare costs ($4686 vs $5604; p=0.416). Short-term disability days and costs were numerically lower in the GLA cohort (16.0 vs 24.5 days; p=0.086 and $2824 vs $4363; p=0.081, respectively). Sensitivity analyses yielded similar findings. CONCLUSIONS Insulin GLA results in better persistence and adherence, compared with NPH insulin, with no overall cost disadvantages. Better persistence and adherence may lead to long-term health benefits for employees with T2DM.

Abstract
Chronic obstructive pulmonary disease (COPD) affects approximately 7% of Americans. COPD impacts productivity and forces 1 in 5 employees ages 45-65 years old to retire prematurely. Our objective was to quantify the direct and indirect costs of COPD in an employed population in the United States. A retrospective analysis using Thomson Reuters MarketScan commercial claims and Health and Productivity (HPM) databases (2000-2007) identified employees (ages 18-65 years) with ≥ 1 COPD medical claim, ≥ 6 month insurance eligibility pre and ≥ 12 months post diagnosis, and ≥ 12 months HPM data post diagnosis. COPD subjects were matched to non-COPD subjects using propensity scores to create a comparison group with similar characteristics. Differences in medical and pharmacy utilization and productivity (absence and short-term disability [STD] days) were examined using negative binomial regression, and cost differences using Heckman selection models. A total of 27,612 COPD patients were matched in a 1:1 ratio to 825,884 non-COPD patients; 80% were ages 36-65 years, and 59% were male. COPD employees had about twice the rate of emergency department visits and hospitalizations compared to non-COPD employees (P<0.0001). The rate of absence and STD days was approximately 1.5 times higher (P<0.0001) compared to non-COPD employees. Yearly direct and indirect expenditures were higher ($3609 and $909, respectively; P<0.0001) for COPD versus non-COPD employees. Excess utilization and associated costs of COPD to employers was quantified. By understanding these costs, employers may evaluate disease management programs and treatment to improve outcomes for employees with COPD. Improved treatment options may reduce the direct and indirect costs of COPD.

Abstract
U.S. health care spending has increased dramatically in the past several decades, consuming 17.6% percent ($2.6 trillion) of GDP in 2010. Although historical spending drivers do not account for this recent increase, two major changes in population health--the rise in obesity and obesity-related chronic disease--provide a likely explanation. This article reviews the contribution that rising treated obesity-related chronic disease prevalence and its associated treatment (spending per treated case) has made to the growth in health care spending. We discuss trends in the clinical incidence of obesity and chronic disease as well as timely advancements in disease detection, treatment, and management. Evidence shows that rising obesity rates are influencing spending largely by increasing the treated prevalence of obesity-related chronic disease. Therefore, preventing individuals from becoming treated cases in the first place is one key way that our country can cut health care spending moving forward.

Abstract
Obesity is associated with impaired health-related quality of life (QOL) and reduced productivity; less is known about the effect of dietary factors. The present study investigated how dietary behaviours, physical activity and BMI relate to weight-specific QOL and work productivity. The study was conducted in thirty-one small blue-collar and service industry worksites in Seattle. Participants were 747 employees (33·5 % non-White). Measures included self-reported servings of fruits and vegetables, dietary behaviours such as fast food consumption, Godin free-time physical activity scores, measured height and weight, Obesity and Weight-Loss QOL (OWLQOL) scores, and Work Limitations Questionnaire scores. Baseline data were analysed using linear mixed models separately for men (n 348) and women (n 399), since sex modified the effects. BMI was negatively associated with OWLQOL in both women (P < 0·001) and men (P < 0·001). The linear effect estimate for OWLQOL scores associated with a one-category increase in BMI was 30 (95 % CI 25, 44) % for women and 14 (95 % CI 10, 17) % for men. BMI was positively associated with productivity loss only in women (exp(slope) = 1·46, 95 % CI 1·02, 2·11, P = 0·04). Eating while doing another activity was negatively associated with OWLQOL scores in men (P = 0·0006, independent of BMI) and with productivity in women (P = 0·04, although the effect diminished when adjusting for BMI). Fast-food meals were associated with decreased productivity in men (P = 0·038, independent of BMI). The results suggest that obesogenic dietary behaviours and higher BMI are associated with decreased QOL and productivity to different degrees in women and men.

Abstract
INTRODUCTION This study was to examine the cumulative number and clustering patterns of low-risk health behaviors (i.e., not currently smoking, not excessive drinking, and physically active) associated with elevation of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), and gamma-glutamyltransferase (GGT) among adults with obesity in the United States. METHODS We estimated the age-adjusted prevalence of elevated ALT, AST, and GGT from 4547 adults with obesity aged ≥ 20 years who participated in the 2005-2008 National Health and Nutrition Examination Survey. The associations between the cumulative number or clustering patterns of low-risk health behaviors and measures of serum ALT, AST, and GGT were assessed using multivariate regression models. RESULTS Adult men who reported having three low-risk health behaviors were 62%, 39%, and 48% less likely to have elevated serum ALT, AST, and GGT, respectively; adult women were 56% and 73% less likely to have elevated serum AST and GGT, respectively, when compared to their respective counterparts who reported having none of the low-risk health behaviors. CONCLUSIONS The findings of this study indicate that, among adults with obesity, having multiple low-risk health behaviors is associated with decreased likelihoods of elevated hepatic enzymes, including ALT in men, AST and GGT in both men and women.

Abstract
A consistent relationship has been demonstrated between obesity and absenteeism in the workplace. However, most studies have focused on primarily sedentary occupational groups. Firefighting is a physically demanding profession that involves significant potential for exposure to dangerous situations and strenuous work. No studies to date have evaluated the impact of obesity on risk for absenteeism among firefighters. We examined the cross-sectional association between BMI and obesity and injury-related absenteeism. BMI, body fat percentage (BF%), waist circumference (WC), injury, and injury-related absenteeism were assessed in 478 career male firefighters. One hundred and fifteen firefighters reported an injury in the previous year and the number of days absent from work due to their injury. BMI was an independent predictor of absenteeism due to injury even after adjustment for confounding variables. Firefighters meeting the definition of class II and III obesity had nearly five times (odds ratio (OR) = 4.89; 95% confidence interval (CI) = 3.63-6.58) the number missed work days due to injury when compared to their normal weight counterparts and their elevated risk was greater than firefighters with class I obesity (OR = 2.71; 95% CI = 2.01-3.65) or those who were overweight (OR = 2.55; 95% CI = 1.90-3.41). The attributable per capita costs of class II and III obesity-related absenteeism over the last year were $1,682.90 per firefighter, $254.00 per firefighter for class I obesity, and $74.41 per firefighter for overweight. Our findings suggest that class II and III obesity were associated with substantial attributable costs to employers and our cost estimates probably underestimate the actual financial burden.

Abstract
BACKGROUND The majority of patients with type 2 diabetes mellitus (T2DM) are overweight or obese. Obesity is a significant risk factor for increased morbidity and mortality in people with T2DM, and increased weight has been shown to worsen glycemic control and increase the risk of diabetes progression. METHODS A search was conducted of the National Library of Medicine (PubMed) for articles published from 1990 to 2009 about the treatments of T2DM, relationship between T2DM and weight gain, obesity-related comorbidities of T2DM, and T2DM therapies associated with increased weight. Reference lists of retrieved articles were reviewed for additional publications. FINDINGS Results from large, prospective clinical trials have shown that weight reduction significantly improves glycemic control and blood pressure in T2DM patients and lowers the risk of progression of T2DM as well as CV disease and cancer. Treatment-related weight gain is a side effect of many oral antidiabetes agents and insulin. The thiazolidinediones (TZD), sulfonylureas, and glinides are associated with weight gain. Despite the weight gain, TZDs also redistribute fat from the central to peripheral compartments, which may lead to a beneficial effect on insulin resistance. Among insulin products, the basal insulin analog detemir is typically associated with a smaller weight increase than human insulin and insulin analog preparations, including glargine, biphasic, and prandial insulin regimens. Alpha-glucosidase inhibitors and dipeptidyl peptidase-4 inhibitors are weight neutral, whereas glucagon-like peptide1-R agonists and metformin are associated with weight loss. DISCUSSION An effective approach to management of the obese patient with diabetes is to communicate the significant benefits of a 1 kg reduction in body weight or prevention of weight gain on glycemic control and reduced morbidity and mortality. LIMITATION This article is based on an extensive literature review rather than the prospective studies needed to define further the effect of weight gain on the management of T2DM. CONCLUSION Weight management should be an integral part of a T2DM treatment strategy that includes selecting oral antidiabetes medications and insulin products that are weight beneficial.

Abstract
The aim of this cross-sectional study was to present nationally representative findings on the co-occurrence of obesity and specific patterns of alcohol use associated with elevated serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), and gamma-glutamyltransferase (GGT) among adults in the United States. We analyzed data from 8,373 adults aged ≥ 20 years who participated in the 2005-2008 National Health and Nutrition Examination Survey. We produced prevalence ratios by using the co-occurrence of obesity (i.e., body mass index ≥ 30.0 kg/m(2) or waist circumference ≥ 102 cm in men and ≥ 88 cm in women) and specific patterns of alcohol use (i.e., non-drinkers, non-excessive drinkers, and excessive drinkers) as a predictor; elevations in serum ALT, AST, and GGT were used as an outcome variable while adjusting for covariates in multivariate regression models. Approximately 34.7% of adult men and 38.6% of adult women in the United States had co-occurrence of obesity and any alcohol use, including 16.4% of men and 9.8% of women who had co-occurrence of obesity and excessive drinking during 2005-2008. When compared to male non-drinkers without obesity after multivariate adjustment, male excessive drinkers with obesity were 3.08 (95% CI: 1.80-5.28), 2.42 (95% CI: 1.80-3.26), and 3.15 (95% CI: 1.82-5.46) times more likely to exhibit elevated serum ALT, AST, and GGT, respectively. Similarly, when compared to female non-drinkers without obesity, female excessive drinkers with obesity were 2.36 (95% CI: 1.38-4.04), 3.27 (95% CI: 1.85-5.78), and 3.43 (95% CI: 2.19-5.40) times more likely to have elevated serum ALT, AST, and GGT, respectively. The co-occurrence of obesity and excessive drinking may place adults at an increased risk for potential liver injury. Our study findings provide support for evidence-based clinical and population-based interventions that integrate health behavior change among adults who have these co-occurring risk factors.

Abstract
BACKGROUND Recent studies suggest that patients undergoing Roux-en-Y gastric bypass (RYGB) for morbid obesity are at risk for hyperoxaluria, nephrolithiasis, and oxalate nephropathy. Our objective was to conduct a long-term prospective longitudinal study to establish the incidence, clinical progression, and severity of hyperoxaluria after RYGB. STUDY DESIGN Patients undergoing RYGB between December 2005 and April 2007 provided 24-hour urine collections for comprehensive stone risk analysis 1 week before and 3 months and 1 and 2 years after surgery. Primary outcomes were changes in 24-hour urinary oxalate excretion and relative supersaturation of calcium oxalate from baseline to 2 years post-RYGB. RESULTS The cohort consisted of 21 patients, including 5 (24%) men and 16 (76%) women. Mean preoperative age and body mass index (calculated as kg/m(2)) were 48.2 +/- 10.5 years (range 25 to 64 years) and 50.5 +/- 9.1 (range 39.7 to 66.6), respectively. Urinary oxalate excretion increased significantly after RYGB (33 +/- 9 mg/day versus 63 +/- 29 mg/day; p <or= 0.001). De novo hyperoxaluria developed in 11 (52%) patients. Increasing age at the time of surgery was predictive of de novo hyperoxaluria developing (odds ratio = 1.162; 95% CI, 1.002-1.347; p = 0.046). The percentage of patients with hypocitraturia increased from 10% at baseline to 48% at 2 years. The relative supersaturation of calcium oxalate was unchanged (1.73 +/- 0.67 versus 2.20 +/- 2.07; p = 0.27). CONCLUSIONS RYGB is associated with a long-term increase in urinary oxalate excretion and decrease in urinary citrate excretion. Although calcium oxalate relative supersaturation increases early in the postoperative period, this returns to baseline with long-term follow-up. These data suggest that patients who have undergone RYGB are at risk for oxalate nephropathy developing.

Abstract
INTRODUCTION Sitagliptin, an oral dipeptidyl peptidase-4 inhibitor, and exenatide, an injectable glucagon-like peptide-1 receptor agonist, are incretin-based therapies for the treatment of type 2 diabetes. This study examined differences in baseline characteristics between patients with type 2 diabetes initiating sitagliptin vs. exenatide treatment in clinical practice settings in the US. METHODS The General Electric Healthcare's Clinical Data Services electronic medical records database, covering 12 million US patients of all ages from 49 states, was used to identify patients with type 2 diabetes, aged > or =30 years, who received their first sitagliptin or exenatide prescription between October 1, 2006 and June 30, 2008 (index period). Patient's medical records, including demographics, diagnoses, procedures, prescriptions, and laboratory results were extracted for the 12-month period (baseline) prior to the date of the first prescription of sitagliptin or exenatide (ie, the index date). Patient baseline profiles were stratified by mono-, dual, or triple therapy and compared between regimens with sitagliptin or exenatide. RESULTS A total of 9543 patients initiated therapy with sitagliptin (n=5589) or exenatide (n=3954) during the index period. For those initiating monotherapy, 876 patients initiated sitagliptin and 476 initiated exenatide. Compared with patients initiating exenatide at baseline, patients on sitagliptin were older (64 vs. 55 years), more likely to be men (45% vs. 35%), and less likely to be obese (60% vs. 87%), and had higher hemoglobin A(1c) (HbA(1c); 7.1% vs. 6.9%), a higher serum creatinine (1.2 mg/dL vs. 1.0 mg/dL), and a higher prevalence of pre-existing cardiovascular complications or microvascular conditions (all P<0.01 for sitagliptin vs. exenatide). For dual therapy, 1885 were prescribed sitagliptin and 1392 were prescribed exenatide. For triple therapy, 2828 were prescribed sitagliptin and 2086 were prescribed exenatide. The observed patient profile differences with dual and triple therapy were generally consistent with those observed with monotherapy. CONCLUSION In a clinical practice setting, there are differences in the baseline characteristics of patients with type 2 diabetes who are prescribed sitagliptin relative to those prescribed exenatide. These findings have important implications for conclusions drawn from observational studies using medical record or claim databases, as estimated clinical and health outcomes measures may be biased due to channeling of patients to different therapies based on different baseline characteristics.

Abstract
The obesity epidemic is also an economic tragedy. This analysis evaluates the economic effects and the potential to improve the well-being of both individual and societal wealth. Econometric techniques should carefully assess the degree to which obesity affects declines in business output, employment, income, and tax revenues at the regional and national levels. Microeconomics assesses lost productivity and associated wages and profit. Macroeconomics assesses trends associated with employment, inflation, interest rates, money supply, and output. To decrease the adverse economic consequences of the obesity epidemic, policy makers must emphasize bariatric surgery as a cost-effective option for qualified patients. Early intervention, education, and tax rebates for obese individuals who undergo bariatric surgery and for medical centers and doctors would likely have positive economic effects on the whole economy in a few years.
