Abstract
Moderate/severe obesity is on the rise in the United States. Weight management includes bariatric surgery, which is effective and can alleviate morbidity and mortality from obesity-associated diseases. However, many individuals are dealing with nutritional complications. Risk factors include: 1) preoperative malnutrition (e.g., vitamin D, iron); 2) decreased food intake (due to reduced hunger and increased satiety, food intolerances, frequent vomiting); 3) inadequate nutrient supplementation (due to poor compliance with multivitamin/multimineral regimen, insufficient amounts of vitamins and/or minerals in supplements); 4) nutrient malabsorption; and 5) inadequate nutritional support (due to lack of follow-up, insufficient monitoring, difficulty in recognizing symptoms of deficiency). For some nutrients (e.g., protein, vitamin B-12, vitamin D), malnutrition issues are reasonably addressed through patient education, routine monitoring, and effective treatment strategies. However, there is little attention paid to other nutrients (e.g., zinc, copper), which if left untreated may have devastating consequences (e.g., hair loss, poor immunity, anemia, defects in neuro-muscular function). This review focuses on malnutrition in essential minerals, including calcium (and vitamin D), iron, zinc, and copper, which commonly occur following popular bariatric procedures. There will be emphasis on the complexities, including confounding factors, related to screening, recognition of symptoms, and, when available, current recommendations for treatment. There is an exceptionally high risk of malnutrition in adolescents and pregnant women and their fetuses, who may be vulnerable to problems in growth and development. More research is required to inform evidence-based recommendations for improving nutritional status following bariatric surgery and optimizing weight loss, metabolic, and nutritional outcomes.

Peer clustering of exercise and eating behaviours among young adults in Sweden: a cross-sectional study of egocentric network data. BMC Public Health 2013; 13:784. [PMID: 23981951 PMCID: PMC3765927 DOI: 10.1186/1471-2458-13-784] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2013] [Accepted: 08/23/2013] [Indexed: 11/17/2022] Open
Abstract
Background Research suggests that the growing prevalence of obesity may be related to the influence of the health behaviours of peers. We look at clustering of exercise and eating behaviours amongst a previously unstudied group, young adults in Sweden. Previous research has mainly been conducted in the United States and Britain, countries that have relatively high rates of obesity. Methods Using ego-alter dyads from the egocentric network data as the unit of analysis, we conduct logistic regressions to investigate the association between ego and alter exercise and eating behaviours. Results Respondents have a significantly greater probability of engaging in regular exercise and eating healthily if a nominated peer also does so. Furthermore, the degree to which this behavior is shared is modulated by the strength of the relationship between the two individuals, with a greater probability of engaging in these behaviours observed when the relationship with the nominated peer is strong relative to when the relationship is weak. However, we find that ego-alter homogeneity in terms of gender and migration status was not associated with a significantly greater probability of behaving in a similar manner to a nominated peer. Furthermore, the status of the nominated peer as a relative or not did not impact the probability that the ego would engage in similar health behaviours to that alter. Conclusions We observe strong associations between ego and alter health behaviours for young adults, consistent with previous research. Although we cannot draw causal inferences, these results suggest that the health behaviours of an individual’s peers may play a role in shaping their own health behaviours.

Abstract
OBJECTIVE The objective of this study was to examine whether teen birth was independently associated with overweight and obesity in a US cohort. STUDY DESIGN We examined whether teen birth is independently associated with overweight and obesity in a multiyear US cohort using the 2001-2010 National Health and Nutrition Examination Survey, a nationally representative cross-sectional survey of the US civilian, noninstitutionalized population. We performed multinomial logistic regression adjusting for survey cohort, age at survey, race, education, and parity. We included women 20-59 years old at the time of survey, with at least 1 live birth, not currently or recently pregnant (unweighted, n = 5220; weighted, n = 48.4 million). Our outcome measure was the effect of teen birth on subsequent overweight and obesity. RESULTS In bivariate analyses, women with a teen birth were significantly more likely than women without a teen birth to be overweight (relative risk ratios [RRRs], 1.61; 95% confidence interval [CI], 1.37-1.90) or obese (RRR, 1.84; 95% CI, 1.56-2.16) at the time of the survey. In multivariate models, women with a teen birth remained significantly more likely to be overweight (adjusted RRR, 1.33; 95% CI, 1.10-1.62) or obese (adjusted RRR, 1.32; 95% CI, 1.09-1.61) than women without a teen birth. CONCLUSION For women in the United States, giving birth as a teen is associated with subsequent overweight/obese status later in life. To inform clinical and policy interventions with the goal to improve the long-term health of teenage mothers, future studies must examine modifiable physiological and sociomedical reasons for early child-bearing and later risk of obesity.

Abstract
AIM To examine the emotional well-being of severely obese Australians with type 2 diabetes, along with markers of social and economic disadvantage, using the Diabetes MILES - Australia dataset. METHODS Diabetes MILES - Australia was a national survey of 3338 adults with diabetes that focused on psychosocial issues; 1795 had type 2 diabetes and reported BMI. We extracted data regarding depression (PHQ-9), anxiety (GAD-7), obesity- and diabetes-related comorbidities, and demographics. The severely obese group (SOG) (BMI ≥ 35; median BMI=41.6) constituted 530 (30%) of the type 2 diabetes respondents and was matched with 530 controls (CG) (BMI<35; median BMI=28.2). Within- and between-group trends were examined. RESULTS The SOG had higher depression scores (median (IQR) 6.0 (3-12)) than CG (5.0 (2-10)); p<0.001, and were more likely to report moderate-severe depressive symptoms (37% versus 27%; p<0.001). The groups did not differ on anxiety. The SOG, compared with the CG, were more likely to live alone (21% versus 17%), receive a disability pension (21% versus 15%), earn ≤$40.000/year (51% versus 41%; all p<0.05), and were less likely to be employed (46% versus 53%), university or higher educated (17% versus 26%), or have health insurance (50% versus 60%; all p ≤ 0.01). Moderate-severe depression was positively associated with cumulative stressors of severe obesity, socioeconomic disadvantage, and obesity- and diabetes-related comorbidity. CONCLUSIONS Severely obese people living with type 2 diabetes have cumulative stressors related to health, disability, demographic and socioeconomic factors, and impaired emotional well-being.

Abstract
Hedonic overconsumption contributing to obesity involves altered activation within the mesolimbic dopamine system. Dysregulation of dopamine signaling in the nucleus accumbens shell (NAS) has been implicated in reward-seeking behaviors, such as binge eating, which contributes to treatment resistance in obesity (Wise, 2012). Direct modulation of the NAS with deep brain stimulation (DBS), a surgical procedure currently under investigation in humans for the treatment of major depression, obsessive-compulsive disorder, and addiction, may also be effective in ameliorating binge eating. Therefore, we examined the ability of DBS of the NAS to block this behavior in mice. c-Fos immunoreactivity was assessed as a marker of DBS-mediated neuronal activation. NAS DBS was found to reduce binge eating and increased c-Fos levels in this region. DBS of the dorsal striatum had no influence on this behavior, demonstrating anatomical specificity for this effect. The dopamine D2 receptor antagonist, raclopride, attenuated the action of DBS, whereas the D1 receptor antagonist, SCH-23390, was ineffective, suggesting that dopamine signaling involving D2 receptors underlies the effect of NAS DBS. To determine the potential translational relevance to the obese state, chronic NAS DBS was also examined in diet-induced obese mice and was found to acutely reduce caloric intake and induce weight loss. Together, these findings support the involvement of the mesolimbic dopamine pathways in the hedonic mechanisms contributing to obesity, and the efficacy of NAS DBS to modulate this system.

Abstract
The prevalence of very severe obesity has increased progressively and faster than other classes of obesity over the last years. It is unclear whether the prevalence of obesity-related complications and health risks increases progressively or reaches a plateau above a certain degree of obesity. The aim of our study was to investigate whether the severity of obesity was correlated with the prevalence of type 2 diabetes mellitus (T2DM), impaired fasting glucose, impaired glucose tolerance (IGT), metabolic syndrome (MS), and cardiovascular diseases (CVDs) in a large cohort of patients with different degrees of obesity. A cross-sectional study was conducted in 938 obese patients without a previous diagnosis of diabetes. Patients were assigned to different categories of obesity: mild-moderate obesity (BMI 30-39.9 kg/m(2)), morbid obesity (BMI 40-49.9 kg/m(2)), and super-obesity (SO, BMI ≥50 kg/m(2)). The prevalence of IGF, IGT, screen-detected T2DM, MS, and CVD was higher in SO patients than in the other groups. Interestingly, the association between SO and either MS or CVD was independent of glucose tolerance status, indicating that factors other than glucose metabolism also favor cardio-metabolic complications in obese patients. In patients without screen-detected T2DM (n = 807), insulin sensitivity and secretion OGTT-derived indexes indicated that SO patients had the worst glucose homeostasis relative to the other categories of obesity, which was indicated by the most reduced disposition index in these patients, a predictor of future T2DM. In conclusion, SO patients have an extremely high prevalence of glucose metabolism deterioration, and cardio-metabolic complications are more prevalent in these patients compared to less obese patients.

Abstract
Obesity has lately been drawing additional attention as a potential cancer risk and, with some exceptions as a prognostic factor. As obesity is a complex issue characterized by different variants, mechanisms and manifestations, its role in cancer development is also a complex problem exceeding the basic fact of the fat content rising above certain limits. Therefore, in the present paper obesity is viewed as a heterogeneous entity, which has distinct connections with cancer pathogenesis. Among other issues, emphasis is made on the state of white and brown adipose tissue, in particular the association of specific brown fat features and the so-called white fat browning with the functions of normal and mutated tumor suppressor genes, such as PTEN and BRCA1. These connections are considered from the viewpoint implying the existence of two types of hormonal carcinogenesis and of hormonal mediation of the genetic predisposition to tumor development, and should be accounted for in prevention and treatment of both obesity and cancer.

OBJECTIVE To evaluate bone turnover markers and bone mineral density (BMD) in women after Roux-en-Y (RYGB) gastric bypass. SUBJECTS AND METHODS In a cross-sectional study, 48 women post-RYGB after three years, and 41 healthy women were evaluated. EVALUATIONS body mass index (BMI); physical activity; food intake; serum levels of calcium, phosphorus, magnesium, alkaline phosphatase, C-terminal telopeptide (CTX), intact parathyroid hormone (PTH), 25-hydroxyvitamin D (25OHD), osteocalcin, urinary calcium and BMD. RESULTS Significantly higher levels were observed for osteocalcin (p < 0.001), CTX (p < 0.001), and PTH (p < 0.001) in the RYGB group when compared with the control group; 25OHD deficiency/insufficiency was more frequent in the RYGB group (p = 0.010), even after adjusted for nutritional status, and it was associated with secondary hyperparathyroidism (p = 0.025); there was no difference in BMD between the groups. Energy (p = 0.036) and protein intake (p = 0.004) were lower in the RYGB group. CONCLUSION Patients submitted to RYGB showed a significantly higher frequency of vitamin D deficiency, secondary hyperparathyroidism, and increase in bone remodeling markers, with no difference in BMD status.

Abstract
Background The obesity epidemic is generally monitored by the proportion of the population whose body mass index (BMI) exceeds 30 kg/m2 but this masks the growing proportion of those who are morbidly obese. This issue is important as the adverse health risks amplify as the level of obesity increases. The aim of this study was to determine how the prevalence of morbid obesity (BMI ≥ 40.0 kg/m2) has changed over a decade among women living in south-eastern Australia. Methods BMI was determined for women in the Geelong Osteoporosis study (GOS) during two time periods, a decade apart. Height and weight were measured for 1,494 women (aged 20–94 years) during 1993–7 and for 1,076 women (aged 20–93 years), 2004–8, and the BMI calculated as weight in kilograms divided by the square of the height in metres (kg/m2). Prevalence estimates were age-standardised to enable direct comparisons. Results Mean BMI increased from 26.0 kg/m2 (95%CI 25.7-26.3) in 1993–7, to 27.1 kg/m2 (95%CI 26.8-27.4) in 2004–8. During this period, the prevalence of morbid obesity increased from 2.5% to 4.2% and the standardised morbidity ratio for morbid obesity was 1.69 (95%CI 1.26-2.27). Increases in mean BMI and prevalence of morbid obesity were observed for all ages and across the socioeconomic spectrum. Conclusions These findings reveal that over a decade, there has been an increase in mean BMI among women residing in south-eastern Australia, resulting in a measurable increase in the prevalence of morbid obesity.

Abstract
OBJECTIVE To assess time trends in measurement error of BMI and the sensitivity/specificity of classifying weight status in the United States by analyzing the difference in BMI between self-reported and measured height and weight. DESIGN AND METHODS Data from 18,394 respondents aged 20-89 years from the National Health and Nutrition Examination Survey (NHANES) from 1999 through 2008 were analyzed. Multiple linear regression and logistic regression models estimated trends in reporting bias and misclassification of weight status by BMI categories, sex, age, and racial/ethnic groups, adjusting for the sampling design. RESULTS We find no evidence that there are time trends in the accuracy of self-report by BMI categories, sex, age, or racial/ethnic groups. The well-known downward bias in self-report has remained stable over the last decade; approximately one in six to seven obese individuals were misclassified as nonobese due to underestimation of BMI. CONCLUSION Increases in obesity rates based on self-reported height and weight are likely to reflect actual weight increases and are not inflated by changes in reporting accuracy.

Abstract
The Yale Food Addiction Scale (YFAS), recently validated in college students and binge eaters, is a means to assess "food addiction" in accordance with DSM-IV criteria for substance dependence. Using online survey methodology, we aimed to validate the use of the YFAS among weight loss surgery (WLS) patients. Participants completed measures about pre-WLS food addiction (YFAS), emotional and binge eating, behavioral activation and inhibition, and pre- and post-WLS substance use. A sample of 67 WLS patients (59.7% Roux-en-Y) was recruited; participants were 62.7% female, 86.6% Caucasian, had a mean age of 42.7; and 53.7% met the criteria for pre-WLS food addiction. Convergent validity was found between the YFAS and measures of emotional eating (r=.368, p<.05) and binge eating (r=.469, p<.05). Discriminant validity was supported in that problematic substance use, behavioral activation, and behavioral inhibition were not associated with YFAS scores. Incremental validity was supported in that the YFAS explained a significant proportion of additional variance in binge eating scores, beyond that predicted by emotional eating (EES) and disordered eating behavior (EAT-26). Those meeting the food addiction criteria had poorer percent total weight loss outcomes (32% vs. 27%). There was a nonsignificant trend towards those with higher food addiction being more likely to admit to post-WLS problematic substance use (i.e., potential "addiction transfer"; 53% vs. 39%). Results support the use of the YFAS as a valid measure of food addiction among WLS patients. Future research with a larger sample may shed light on potentially important relationships between pre-surgical food addiction and both weight and substance use outcomes.

Abstract
Obesity has substantially increased in recent decades and is now one of the major global health problems. The large obesity-related health burden negatively impacts many relevant health outcomes (e.g. quality of life, disability, mortality) and leads to increased healthcare utilization. This excess service use is the main driver behind high healthcare costs of obese individuals. Findings indicate that costs rise curvilinearly with increasing body mass index, especially among the obese. As more individuals of a country's population become obese, a larger share of total annual national healthcare expenditure is spent on obesity and obesity-related health problems. In addition to escalating healthcare costs, obesity goes along with indirect costs through decreases in workforce productivity. The empirical evidence has shown beyond doubt that obesity negatively impacts individuals, healthcare systems, employers, and the economy as a whole. This article provides a brief overview of selected economic consequences associated with excess-weight.

Abstract
BACKGROUND Obesity has reached epidemic proportions in the United States. Recently, obesity, especially morbid obesity, has been linked to increased rates of dislocation after THA. The reasons are unclear. Soft tissue engagement caused by increased thigh girth has been proposed as a possible mechanism for decreased joint stability. QUESTIONS/PURPOSES We asked (1) whether thigh soft tissue impingement could decrease THA stability, and if so, at what level of BMI this effect might become evident; and (2) how THA construct factors (eg, head size, neck offset, cup abduction) might affect stability in the morbidly obese. METHODS The obesity effect was explored by augmenting a physically validated finite element model of a total hip construct previously comprising just implant hardware and periarticular (capsular) soft tissue. The model augmentation involved using anatomic and anthropometric data to include graded levels of increased thigh girth. Parametric computations were run to assess joint stability for two head sizes (28 and 36 mm), for normal versus high neck offset, and for multiple cup abduction angles. RESULTS Thigh soft tissue impingement lowered the resistance to dislocation for BMIs of 40 or greater. Dislocation risk increased monotonically above this threshold as a function of cup abduction angle, independent of hardware impingement events. Increased head diameter did not substantially improve joint stability. High-offset necks decreased the dislocation risk. CONCLUSIONS Excessive obesity creates conditions that compromise stability of THAs. Given such conditions, our model suggests reduced cup abduction, high neck offset, and full-cup coverage would reduce the risks of dislocation events.

Abstract
OBJECTIVE Severe obesity (body mass index [BMI] ≥40 kg/m(2)) is a serious public health concern. Although bariatric surgery is an efficacious treatment approach, it is limited in reach; thus, nonsurgical treatment alternatives are needed. We examined the 4-year effects of an intensive lifestyle intervention on body weight and cardiovascular disease risk factors among severely obese, compared with overweight (25 ≤BMI <30), class I (30 ≤BMI <35), and class II obese (35 ≤BMI <40) participants. METHODS There were 5145 individuals with type 2 diabetes (45-76 years, BMI ≥25 kg/m(2)) randomized to an intensive lifestyle intervention or diabetes support and education. The lifestyle intervention group received a behavioral weight loss program that included group and individual meetings, a ≥10% weight loss goal, calorie restriction, and increased physical activity. Diabetes support and education received a less intense educational intervention. Four-year changes in body weight and cardiovascular disease risk factors were assessed. RESULTS Across BMI categories, 4-year changes in body weight were significantly greater in lifestyle participants compared with diabetes support and education (Ps <.05). At year 4, severely obese lifestyle participants lost 4.9%±8.5%, which was similar to class I (4.8%±7.2%) and class II obese participants (4.4%±7.6%), and significantly greater than overweight participants (3.4%±7.0%; P <.05). Four-year changes in low-density-lipoprotein cholesterol, triglycerides, diastolic blood pressure, HbA(1c), and blood glucose were similar across BMI categories in lifestyle participants; however, the severely obese had less favorable improvements in high-density-lipoprotein cholesterol (3.1±0.4 mg/dL) and systolic blood pressure (-1.4±0.7 mm Hg) compared with the less obese (Ps <.05). CONCLUSION Lifestyle interventions can result in important long-term weight losses and improvements in cardiovascular disease risk factors among a significant proportion of severely obese individuals.

Abstract
Carotid intima-media-thickness (cIMT) and carotid distensibility (distensibility), structural and functional properties of carotid arteries respectively, are early markers, as well as strong predictors of cardiovascular disease (CVD). The characteristic of these two parameters in individuals with BMI>40.0 kg/m(2) (Class III obesity), however, are largely unknown. The present study was designed to document cIMT and distensibility in this population and to relate these to other factors with established association with CVD in obesity. The study included 96 subjects (65 with BMI>40.0 kg/m(2) and 31, age- and gender-matched, with BMI of 18.5 to 30.0 kg/m(2)). cIMT and distensibility were measured by non-invasive high resolution ultrasonography, circulatory CD133(+)/KDR(+) angiogenic cells and endothelial microparticles (EMP) by flow cytometry, and plasma levels of adipokines, growth factors and cytokines by Luminex immunoassay kits. The study results demonstrated increased cIMT (0.62±0.11 mm vs. 0.54±0.08 mm, P = 0.0002) and reduced distensibility (22.52±10.79 10(-3)kpa(-1)vs. 29.91±12.37 10(-3)kpa(-1), P<0.05) in individuals with BMI>40.0 kg/m(2). Both cIMT and distensibility were significantly associated with traditional CVD risk factors, adiposity/adipokines and inflammatory markers but had no association with circulating angiogenic cells. We also demonstrated, for the first time, elevated plasma EMP levels in individuals with BMI>40.0 kg/m(2). In conclusion, cIMT is increased and distensibility reduced in Class III obesity with the changes predominantly related to conventional CVD risk factors present in this condition, demonstrating that both cIMT and distensibility remain as CVD markers in Class III obesity.

Abstract
AIMS To compare effectiveness of a 1-year weight loss program in moderately and severely obese patients. METHODS The study sample included 311 obese patients participating in a weight loss program, which comprised a 12-week weight reduction phase (low-calorie formula diet) and a 40-week weight maintenance phase. Body weight and glucose and lipid values were determined at the beginning of the program as well as after the weight reduction and the weight maintenance phase. Participants were analyzed according to their BMI class at baseline (30-34.9 kg/m²; 35-39.9 kg/m²; 40-44.9 kg/m²; 45-49.9 kg/m²; ≥50 kg/m²). Furthermore, moderately obese patients (BMI < 40 kg/m²) were compared to severely obese participants (BMI ≥ 40 kg/m²). RESULTS Out of 311 participants, 217 individuals completed the program. Their mean baseline BMI was 41.8 ± 0.5 kg/m². Average weight loss was 17.9 ± 0.6%, resulting in a BMI of 34.3 ± 0.4 kg/m² after 1 year (p < 0.001). Overall weight loss was not significantly different in moderately and severely obese participants. Yet, severely obese participants achieved greater weight loss during the weight maintenance phase than moderately obese participants (-3.1 ± 0.7% vs. -1.2 ± 0.6%; p = 0.04). Improvements in lipid profiles and glucose metabolism were found throughout all BMI classes. CONCLUSION 1-year weight loss intervention improves body weight as well as lipid and glucose metabolism not only in moderately, but also in severely obese individuals.

Abstract
We examined the effects of a 10-14-weeks inpatient lifestyle modification program, including minimum 90 min of physical activity (PA) five days/week, on body composition, CVD risk factors, and eating behavior in 139 obese subjects (BMI 42.6 ± 5.2 kg/m²). Completion rate was 71% (n = 71) in the intensive lifestyle intervention (ILI) group and 85% (n = 33) among waiting list controls. Compared to controls body weight (-17.0 (95% CI: -18.7, -15.3) kg, P < 0.0001), fat mass (-15.2 (95% CI: -17.4, -13.1) kg, P < 0.0001), fat free mass (-1.2 (95% CI: -2.2, -0.2) kg, P = 0.016) and visceral fat (-86.6(95% CI: -97.4, -75.7) cm², P < 0.0001) were reduced in the ILI-group after 10-14 weeks. Within the ILI-group weight loss was -23.8 (95% CI: -25.9, -21.7) kg, P < 0.0001 and -20.3 (95% CI: -23.3, -17.3) kg, P < 0.0001, after six and 12 months, respectively. Systolic BP, glucose, triglycerides, and LDL-C were reduced, and HDL-C was increased (all P ≤ 0.006) after 10-14 weeks within the ILI group. The reduction in glucose and increase in HDL-C were sustained after 12 months (all P < 0.0001). After one year, weight loss was related to increased cognitive restraint and decreased uncontrolled eating (all P < 0.05). Thus, ILI including high volume of PA resulted in weight loss with almost maintenance of fat-free mass, favorable changes in CVD risk factors, and eating behavior in subjects with severe obesity.

Abstract
Chronic respiratory failure (CRF) develops in a minority of obese patients. Noninvasive mechanical ventilation (NIMV) is a new optional treatment for such patients. The aim of this study was to evaluate the effectiveness of NIMV in obese patients with CRF. The material of the study consisted of 34 obese patients (body mass index 47.3 ± 7.9 kg/m(2)) with CRF (PaO2 = 6.40 ± 0.93 kPa and PaCO2 = 8.67 ± 2.13 kPa) who were hypoxemic despite an optimal therapy. Thirteen patients had an overlap syndrome (OS) - chronic obstructive pulmonary disease (COPD) coexisting with obstructive sleep apnea syndrome (OSAS) and 21 patients had obesity-hypoventilation syndrome (OHS). Ventilation parameters were determined during polysomnography. The efficacy of NIMV was evaluated on the fifth day and after 1 year's home treatment. We observed a significant increase in the mean blood oxygen saturation during sleep in all patients; the increase was greater in patients with OHS (92.6 ± 1.4 %) than in patients with OS (90.4 ± 1.8 %). There was a significant improvement of diurnal PaO2 and PaCO2 on the fifth day of NIMV (mean PaO2 increase 2.1 kPa and PaCO2 decrease 0.9 kPa) and also after 1 year of home NIMV (mean PaO2 increase 1.9 kPa and PaCO2 decrease 2.4 kPa). Only one patient stopped treatment because of lack of tolerance during the observation period (1-3 years). In conclusion, NIMV is an effective and well tolerated treatment option in obese patients with CRF resulting in a rapid relief of respiratory disorders during sleep and a gradual, long-term improvement of gas exchange during the day, particularly in patients with OHS.

Abstract
BACKGROUND Obesity is a national health problem regularly confronting medical professionals. Although reduced-energy (kilocalorie [kcal]) eating and increased exercise will reliably reduce weight, these behaviors have been highly resistant to sustained change. OBJECTIVE To control eating using theory-based cognitive-behavioral methods that leverage the positive psychosocial effects of newly initiated exercise as an alternate to typical approaches of education about appropriate nutrition. METHOD A woman, age 48 years, with morbid obesity initiated exercise through a 6-month exercise support protocol based on social cognitive and self-efficacy theory (The Coach Approach). This program was followed by periodic individual meetings with a wellness professional intended to transfer behavioral skills learned to adapt to regular exercise, to then control eating. There was consistent recording of exercises completed, foods consumed, various psychosocial and lifestyle factors, and weight. RESULTS Over the 4.4 years reported, weight decreased from 117.6 kg to 59.0 kg, and body mass index (BMI) decreased from 43.1 kg/m(2) to 21.6 kg/m(2). Mean energy intake initially decreased to 1792 kcal/day and further dropped to 1453 kcal/day by the end of the weight-loss phase. Consistent with theory, use of self-regulatory skills, self-efficacy, and overall mood significantly predicted both increased exercise and decreased energy intake. Morbid obesity was reduced to a healthy weight within 3.1 years, and weight was maintained in the healthy range through the present (1.3 years later). CONCLUSION This case supports theory-based propositions that exercise-induced changes in self-regulation, self-efficacy, and mood transfer to and reinforce improvements in corresponding psychosocial factors related to controlled eating.

Abstract
BACKGROUND Studies of weight and health-related quality of life (HRQOL) generally focus on white populations. This analysis examines the association between clinical weight categories and physical HRQOL in five racial/ethnic groups of older women and determines the extent to which emotional/psychological (social support, caregiver burden) and physical health (diabetes, osteoarthritis) factors modify this relationship. METHODS The cross-sectional analysis, completed in 2007, used baseline data from postmenopausal women enrolled in the Women's Health Initiative (WHI) during the 5-year recruitment period (1993-1998). RESULTS Of 161,393 women, 83% were non-Hispanic white, 9% were African American, 4% were Hispanic/Latina, 3% were Asian/Pacific Islander, and <1% were American Indian/Alaska Native. Obesity (body mass index [BMI] > or =30 kg/m(2)) was most common in non-Asian minority groups. Regression modeling showed higher odds of poor physical HRQOL with increasing weight category in all groups. In the total sample, these odds were at least 6 times as high in women with class 3 obesity as in women of normal weight and were only mildly attenuated after the analysis adjusted for emotional/psychological factors. Further adjustment for physical health factors made odds ratio (OR) estimates drop from 2.36 to 1.59 for class 1 obesity and from 6.96 to 3.71 for class 3 obesity. This pattern generally persisted within each racial/ethnic group. CONCLUSIONS Heavier weight negatively affects physical HRQOL in postmenopausal women across diverse racial/ethnic backgrounds. Weight-relevant physical health factors have a greater impact on this weight-HRQOL association than do emotional/psychological factors.

Abstract
BACKGROUND Obesity has become a major epidemic in the United States. Although research suggests obesity does not increase major morbidity or mortality after thoracic operations, it likely results in greater use of health care resources. METHODS We examined all patients in The Society of Thoracic Surgeons General Thoracic Surgery database with primary lung cancer who underwent lobectomy from 2006 to 2010. We investigated the impact of body mass index (BMI) on total operating room time using a linear mixed-effects regression model and multiple imputations to account for missing data. Secondary outcomes included postoperative length of stay and 30-day mortality. Covariates included age, sex, race, forced expiratory volume, smoking status, Zubrod score, prior chemotherapy or radiation, steroid use, number of comorbidities, surgical approach, hospital lobectomy volume, hospital percent obesity, and the addition of mediastinoscopy or wedge resection. RESULTS A total of 19,337 patients were included. The mean BMI was 27.3 kg/m2, with 4,898 patients (25.3%) having a BMI of 30 kg/m2 or greater. The mean total operating room time, length of stay, and 30-day mortality were 240 minutes, 6.7 days, and 1.8%, respectively. For every 10-unit increase in BMI, mean operating room time increased by 7.2 minutes (range, 4.8 to 8.4 minutes; p<0.0001). Higher hospital lobectomy volume and hospital percentage of obese patients did not affect the association between BMI and operative time. Body mass index was not associated with 30-day mortality or increased length of stay. CONCLUSIONS Increased BMI is associated with increased total operating room time, regardless of institutional experience with obese patients.

Abstract
Bipolar disorder (BD) is associated with obesity, overweight, and abdominal obesity, and BD individuals with obesity have a greater illness burden. Factors related to BD, its treatment, and the individual may all contribute to BD's association with obesity. Management strategies for the obese BD patient include use of medications with better metabolic profiles, lifestyle interventions, and adjunctive pharmacotherapy for weight loss. Obesity-related psychiatric and medical comorbidities should also be assessed and managed. Bariatric surgery may be an option for carefully selected patients. Greater research into the theoretical underpinnings and clinical management of the BD-obesity connection is needed.

Abstract
Recent advances in human genetics have revealed a number of genes influencing the susceptibility to obesity and related conditions, but it is likely that their contribution to disease is contingent on numerous environmental factors. As the obesity epidemic has occurred over a relatively short period of recent history, use of gene-by-year of birth analysis may be a useful approach for quantifying, in aggregate, the interaction between genetic susceptibility to obesity and the numerous known and unknown environmental factors that have changed during nutrition and health transitions globally during this recent increase in obesity rates. Evidence from one family-based longitudinal study set in the United States is showcased, which points to significant increases in the effect of common genetic variants on childhood and adulthood BMI over an 80 year period spanning from 1929 to the present. First, common genetic variants previously known to be associated with age at menarche through genome-wide association analysis were examined in aggregate using a genetic risk score approach. The menarche genetic risk score, composed of 42 single-nucleotide polymorphisms (SNPs) was significantly associated with peri-pubertal BMI in both boys and girls, but the magnitude of the association was strongly dependent on year of birth, with greater effect as birth year increased. Second, a similar approach was taken using instead a BMI genetic risk score composed of 32 common variants previously found to be associated with BMI. This score was strongly associated with adulthood BMI, waist circumference, and skinfold thickness, as expected, but the magnitude of the association increased with later year of birth. Such gene-environment interactions call for greater focus on the mechanisms by which environmental factors impact the functional output of the human genome, including how epigenetic mechanisms may be altered during social, technological, nutritional, and ecological transitions.

Abstract
BACKGROUND AND PURPOSE Roux-en-Y gastric bypass (RYGB) surgery, a mixed malabsorptive/restrictive procedure, is associated with enteric hyperoxaluria and an increased risk of kidney stones. The incidence of nephrolithiasis after purely restrictive bariatric procedures such as adjustable gastric banding or sleeve gastrectomy has not been well described. We aim to analyze the incidence of kidney stones in patients who undergo either adjustable gastric banding or sleeve gastrectomy. PATIENTS AND METHODS In a retrospective study, we analyzed a pool of 332 patients who underwent adjustable gastric banding and 85 patients who underwent sleeve gastrectomy at the University of California, San Diego Center for the Treatment for Obesity within a 54-month period (September 2006 to February 2011). The primary outcomes of urinary calculus diagnosis and surgical treatment were investigated using manual chart review and International Classification of Diseases and Related Health Problems-9 code electronic search. RESULTS Within the adjustable gastric banding cohort, we found a person-time incidence rate of 3.40 stone diagnoses per 1000 person-years. Within the sleeve gastrectomy cohort, we found a person-time incidence rate of 5.25 stone diagnoses per 1000 person-years. CONCLUSIONS Questions remain whether purely restrictive bariatric procedures such as sleeve gastrectomy or adjustable gastric banding avoid the risk of kidney stones. Our study demonstrates a very low incidence of kidney stones after restrictive bariatric procedures, although larger sample sizes, longer follow-up times, and controlled prospective studies are necessary to validate this finding.

Abstract
PURPOSE To present software for supervised automatic quantification of visceral and subcutaneous adipose tissue (VAT, SAT) and evaluates its performance in terms of reliability, interobserver variation, and processing time, since fully automatic segmentation of fat-fraction magnetic resonance imaging (MRI) is fast but susceptible to anatomical variations and artifacts, particularly for advanced stages of obesity. MATERIALS AND METHODS Twenty morbidly obese patients (average BMI 44 kg/m(2) ) underwent 1.5-T MRI using a double-echo gradient-echo sequence. Fully automatic analysis (FAA) required no user interaction, while supervised automatic analysis (SAA) involved review and manual correction of the FAA results by two observers. Standard of reference was provided by manual segmentation analysis (MSA). RESULTS Average processing times per patient were 6, 6+4, and 21 minutes for FAA, SAA, and MSA (P < 0.001), respectively. For VAT/SAT assessment, Pearson correlation coefficients, mean (bias), and standard deviations of the differences were R = 0.950, +0.003, and 0.043 between FAA and MSA and R = 0.981, +0.009, and 0.027 between SAA and MSA. Interobserver variation and intraclass correlation were 3.1% and 0.996 for SAA, and 6.6% and 0.986 for MSA, respectively. CONCLUSION The presented supervised automatic approach provides a reliable option for MRI-based fat quantification in morbidly obese patients and was much faster than manual analysis.

Abstract
BACKGROUND & AIMS Gastrointestinal (GI) diseases account for substantial morbidity, mortality, and cost. Statistical analyses of the most recent data are necessary to guide GI research, education, and clinical practice. We estimate the burden of GI disease in the United States. METHODS We collected information on the epidemiology of GI diseases (including cancers) and symptoms, along with data on resource utilization, quality of life, impairments to work and activity, morbidity, and mortality. These data were obtained from the National Ambulatory Medical Care Survey; National Health and Wellness Survey; Nationwide Inpatient Sample; Surveillance, Epidemiology, and End Results Program; National Vital Statistics System; Thompson Reuters MarketScan; Medicare; Medicaid; and the Clinical Outcomes Research Initiative's National Endoscopic Database. We estimated endoscopic use and costs and examined trends in endoscopic procedure. RESULTS Abdominal pain was the most common GI symptom that prompted a clinic visit (15.9 million visits). Gastroesophageal reflux was the most common GI diagnosis (8.9 million visits). Hospitalizations and mortality from Clostridium difficile infection have doubled in the last 10 years. Acute pancreatitis was the most common reason for hospitalization (274,119 discharges). Colorectal cancer accounted for more than half of all GI cancers and was the leading cause of GI-related mortality (52,394 deaths). There were 6.9 million upper, 11.5 million lower, and 228,000 biliary endoscopies performed in 2009. The total cost for outpatient GI endoscopy examinations was $32.4 billion. CONCLUSIONS GI diseases are a source of substantial morbidity, mortality, and cost in the United States.

Abstract
Obesity is a chronic metabolic disorder affecting half a billion people worldwide. Major difficulties in managing obesity are the cessation of continued weight loss in patients after an initial period of responsiveness and rebound to pretreatment weight. It is conceivable that chronic weight gain unrelated to physiological needs induces an allostatic regulatory state that defends a supranormal adipose mass despite its maladaptive consequences. To challenge this hypothesis, we generated a reversible genetic mouse model of early-onset hyperphagia and severe obesity by selectively blocking the expression of the proopiomelanocortin gene (Pomc) in hypothalamic neurons. Eutopic reactivation of central POMC transmission at different stages of overweight progression normalized or greatly reduced food intake in these obesity-programmed mice. Hypothalamic Pomc rescue also attenuated comorbidities such as hyperglycemia, hyperinsulinemia, and hepatic steatosis and normalized locomotor activity. However, effectiveness of treatment to normalize body weight and adiposity declined progressively as the level of obesity at the time of Pomc induction increased. Thus, our study using a novel reversible monogenic obesity model reveals the critical importance of early intervention for the prevention of subsequent allostatic overload that auto-perpetuates obesity.

Abstract
OBJECTIVE To investigate energy expenditure in lean and obese individuals, focusing particularly on physical activity and severely obese individuals. DESIGN Total daily energy expenditure (TDEE) was assessed using doubly labeled water, resting metabolic rate (RMR) by indirect calorimetry, activity energy expenditure (AEE) by difference and time spent in physical activity by multisensor activity monitors. SUBJECTS In all, 177 lean, Class I and severely obese individuals (age 31-56 years, body mass index 20-64 kg m(-2)) were analyzed. RESULTS All components of energy expenditure were elevated in obese individuals. For example, TDEE was 2404±95 kcal per day in lean and 3244±48 kcal per day in Class III obese individuals. After appropriate adjustment, RMR was similar in all groups. Analysis of AEE by body weight and obesity class indicated a lower AEE in obese individuals. Confirming lower physical activity, obese individuals spent less time engaged in moderate-to-vigorous physical activity (2.7±1.3, 1.8±0.6, 2.0±1.4 and 1.2±1.0 h per day in lean, Class I, Class II and Class III individuals) and more time in sedentary behaviors. CONCLUSIONS There was no indication of metabolic efficiency in even the severely obese, as adjusted RMR was similar across all groups. The higher AEE observed in the obese is consistent with a higher cost of activities due to higher body weight. However, the magnitude of the higher AEE (20-25% higher in obese individuals) is lower than expected (weight approximately 100% higher in Class III individuals). Confirming a lower volume of physical activity in the obese, the total time spent in moderate-to-vigorous physical activity and average daily metabolic equivalent of task level were lower with increasing obesity. These findings demonstrate that high body weight in obese individuals leads to a high TDEE and AEE, which masks the fact that they are less physically active, which can be influenced by duration or intensity of activity, than in lean individuals.

Abstract
Visceral adipose tissue (VAT) is associated with abnormal cardiovascular and metabolic profiles. Total VAT volume of the abdominal compartment by magnetic resonance imaging (MRI) is the gold-standard measurement for VAT but is costly and time consuming. Prior studies suggest VAT area on a single slice MR image may serve as a surrogate for total VAT volume but it is unknown if this relationship is maintained in overweight and obese men and women. Untreated sleep apnea subjects enrolled into the Icelandic Sleep Apnea Cohort (ISAC) underwent abdominal MRI. VAT area and subcutaneous adipose tissue (SAT) area at the L2-L3 and L4-L5 interspaces and total VAT and SAT volumes were determined by manual examination using image analysis software; 539 men and 129 women with mean ages of 54.1 and 58.8 years and mean BMI of 32.2 kg/m(2) and 33.7 kg/m(2), respectively, were studied. Mean total VAT volume was 40% smaller and mean total SAT was 25% larger among females compared with males. The correlation with VAT volume was significantly larger for L2-L3 VAT area (r = 0.96) compared to L4-L5 VAT area (r = 0.83). The difference in correlation coefficients was statistically significant (nonparametric bootstrap P < 0.001 with 95% confidence interval (CI) for the difference from 0.11 to 0.15. VAT area at L2-L3 was also significantly better correlated with VAT volume than traditional anthropometric variables. Linear regression analyses demonstrated that L2-L3 area alone was sufficient for predicting total VAT volume and that the nature of the linear association was maintained across all levels of obesity and in both genders.

Abstract
There are high rates of suicide ideation and/or behavior in severely obese individuals. The potential contributors to suicide ideation in a sample of 334 severely obese bariatric surgery candidates was explored. Lack of college education, a history of suicide ideation and/or behavior, psychological distress, hopelessness, loneliness, history of physical and/or sexual abuse, and lifetime major depression were associated with current suicide ideation. Some of the correlates of suicide ideation in severely obese bariatric surgery-seeking samples are similar to those found in the general community and this knowledge may serve to improve the psychological assessment and care for this group.

Abstract
Risk assessment of the cervical spine prior to manual therapy interventions is currently a contentious topic, highlighted by recent suggestions in the medical press (http://www.bmj.com/content/344/bmj.e3679), that manipulative therapy should be abandoned because of the perceived risk. This paper addresses the issue of manual therapists using blood pressure measurement as an aid to clinical reasoning and decision making. The authors' use a case series of three neuromusculoskeletal presentations, which support the contention that blood pressure recording can prove to be an appropriate objective test for assessment prior to manual therapy interventions. Furthermore, it is suggested that blood pressure testing may provide direction for risk assessment and/or the management of patients across all populations and age groups as part of a holistic 'vascular profiling' approach to clinical reasoning and decision making.

Abstract
OBJECTIVE The aim of this study was to evaluate the association between baseline body mass index (BMI) and treatment outcome after a brief interdisciplinary fibromyalgia treatment program. DESIGN Subjects (n = 477) with fibromyalgia participated in the fibromyalgia treatment program. They completed the Fibromyalgia Impact Questionnaire (FIQ) and the Short Form-36 Health Status Questionnaire (SF-36) at baseline and 6 to 12 mos after the fibromyalgia treatment program. Posttreatment changes in FIQ and SF-36 scores were compared after stratifying participants into four BMI groups: nonobese, overweight, moderately obese, and severely obese. RESULTS All BMI groups achieved significant improvement in the FIQ total score; the FIQ subscales feel good, pain, fatigue, and morning tiredness; and the SF-36 subscales pain index, vitality, social functioning, and mental health index. Posttreatment changes in mean scores for each subscale generally did not differ significantly across BMI groups after adjusting for age and baseline scores. However, the SF-36 subscale scores of physical functioning and role-emotional were significantly less improved in the severely obese compared with the nonobese. CONCLUSIONS Baseline BMI did not affect response to the fibromyalgia treatment program, as measured by the FIQ total score or SF-36 physical and mental component summary scores. However, the severely obese group showed less improvement compared with the nonobese group in the SF-36 physical functioning and role-emotional subscales.

Abstract
OBJECTIVE To report experience with laparoscopic sleeve gastrectomy (LSG) in 108 severely obese children and adolescents. BACKGROUND Obesity during childhood and adolescence can be accompanied by serious long-term adverse health and longevity outcomes. With increased use of bariatric surgery to treat obesity in these patients, diverse guidelines have been published, most of which exclude children aged younger than 14 years. Few reports describe LSG in children and adolescents, delaying determining its safety and effectiveness and developing guidance regarding its use. METHODS A retrospective review of LSG performed from March 2008 through February 2011 by a single surgeon at King Saud University Hospitals, Riyadh, Saudi Arabia, included 108 patients aged 5 through 21 years. RESULTS Patients attending follow-up visits at 3 (n = 88), 6 (n = 76), 12 (n = 41), and 24 (n = 8) months postoperatively experienced median excess weight loss (EWL) of 28.9%, 48.1%, 61.3%, and 62.3%, respectively. At 6 and 12 months follow-up, 42.1% (n = 32) and 73.2% (n = 30) of patients achieved at least 50% EWL, whereas 7.9% (n = 6) and 4.9% (n = 2) had 25% or less EWL, respectively. There were no serious postoperative complications and no adverse sequelae developed during the current follow-up. Available comorbidity data indicate resolution of dyslipidemia, 21 of 30 (70.0%); hypertension, 27 of 36 (75.0%); prehypertension, 15 of 18 (83.3%); symptoms of obstructive sleep apnea, 20 of 22 (90.9%); diabetes, 15 of 16 (93.8%); and prediabetes, 11 of 11 (100.0%). CONCLUSIONS LSG resulted in successful short-term weight loss in more than 90% of pediatric patients and 70% or more comorbidity resolution during up to 24 months of follow-up. Long-term data are necessary to evaluate persistence of weight loss and maturation to adulthood.

Abstract
OBJECTIVE The present meta-regression pools data from reports of long-term follow-up (>2 years) to assess durability of the efficacy associated with Roux-en-Y gastric bypass (RYGB) surgery. DATA SOURCES Medline and PubMed searches for articles pertaining to long-term weight loss after RYGB surgery were performed. BACKGROUND Various studies have consistently shown short-term (<2 years) efficacy of RYGB surgery for morbid obesity, corroborated by meta-analytic techniques. Relatively few studies have assessed efficacy over longer periods of time. This is the first meta-analysis to analyze long-term effects of RYGB surgery on weight loss. METHODS Twenty-two reports with a total of 4206 patient cases were included. Sixteen of the 22 studies had multiple follow-up times, ranging from 2 to 12.3 years (mean: 3.6 years). An inverse variance weighted model and meta-regression were used to generate the pooled percent mean excess weight loss (EWL) and the durability of EWL over time, respectively. RESULTS Meta-regression did not reveal any significant change in EWL over time. Pooled mean EWL was 66.5%, and there was no significant association between EWL and length of follow-up. CONCLUSIONS Pooling data from multiple studies meta-analytically revealed that weight loss after RYGB is maintained over the long-term. Further investigation would be necessary to ascertain similar durability in comorbidity reduction after RYGB surgery.
