Efficacy of the enhanced recovery after surgery protocol on reducing surgical disparities related to overweight/obesity in deep inferior epigastric perforator flap breast reconstruction.

BACKGROUND: When choosing a method of deep inferior epigastric perforator (DIEP) flap for breast reconstruction, concerns regarding the potentially detrimental effects of obesity on postoperative recovery remain. Enhanced recovery after surgery (ERAS) is known to facilitate rapid postoperative recovery. This study aimed to examine the effect of the ERAS protocol on the disparity between normal/underweight and overweight/obese patients after DIEP flap breast reconstruction. METHODS: A retrospective review of consecutive patients who underwent DIEP flap breast reconstruction between January 2015 and November 2022 was conducted. The patients were categorized into two groups: pre-ERAS and post-ERAS. In each group, associations between overweight/obese patients (BMI ≥25 kg/m2 ) and postoperative course were evaluated. RESULTS: In total, 217 patients in the pre-ERAS group (including 71 overweight/obese) and 165 in the post-ERAS group (including 58 overweight/obese) were analyzed. The post-ERAS group had shorter length of stay (LOS) (8.0 versus 7.0 days, p-value <.001) and lower postoperative pain scores (5.0 versus 3.0 at postoperative day (POD) 1, p-value <.001) than the pre-ERAS group. The complication profiles did not differ according to ERAS adoption. In the pre-ERAS group, overweight/obese patients showed a significantly longer LOS (8.0 versus 9.0 days, p-value = .017) and a higher postoperative pain score (3.0 versus 4.0 at POD 2, p-value = .018) than normal/underweight patients; however, these differences disappeared in the post-ERAS group, showing similar LOS, pain scores, and analgesic consumption. CONCLUSIONS: Implementation of the ERAS protocol in DIEP free-flap breast reconstruction may reduce overweight/obesity-related disparities in postoperative recovery.

Adherence to a Traditional Mexican Diet Is Associated with Lower Hepatic Steatosis in US-Born Hispanics of Mexican Descent with Overweight or Obesity.

Hispanics of Mexican descent have disproportionate rates of non-alcoholic fatty liver disease (NAFLD). The purpose of this work is to investigate the association between the traditional Mexican diet score (tMexS) and hepatic steatosis and fibrosis, two NAFLD-related clinical endpoints, in Hispanic adults of Mexican descent. Data from 280 Hispanic adults of Mexican descent (n = 102 men, 178 women) with overweight or obesity enrolled in a cross-sectional observational study were analyzed. The tMexS was calculated from 24 h dietary recalls. Hepatic steatosis and fibrosis measurements were assessed using transient elastography (Fibroscan®). Linear regression models testing the association between tMexS and hepatic steatosis and fibrosis were run individually and through the stratification of significant modifiers. Mean tMexS were 5.9 ± 2.1, hepatic steatosis scores were 288.9 ± 48.9 dB/m, and fibrosis scores were 5.6 ± 2.2 kPa. Among the US-born group, with every point increase in the tMexS, there was a statistically significant 5.7 lower hepatic steatosis point (95% CI: -10.9, -0.6, p-value = 0.07). Higher adherence to a traditional Mexican diet was associated with lower hepatic steatosis in US-born Hispanics of Mexican descent. Findings from the current work may serve to inform future culturally relevant interventions for NAFLD prevention and management in individuals of Mexican descent.

Independent and joint associations of cardiorespiratory fitness and BMI with dementia risk: the Cooper Center Longitudinal Study.

OBJECTIVE: This study aimed to examine the association of midlife fitness and body mass index (BMI) with incident dementia later in life. DESIGN AND PARTICIPANTS: A cohort study of 6428 individuals (mean age 50.9±7.6 years) from the Cooper Center Longitudinal Study. MEASURES: Cardiorespiratory fitness and BMI were assessed twice (1970-1999) during visits to the Cooper Clinic, a preventive medicine clinic in Dallas, Texas. These measures were examined as continuous and categorical variables. As continuous variables, fitness and BMI were examined at baseline (averaged of two examinations) and as absolute change between exams (mean time 2.1±1.8 years). Variables were categorised: unfit versus fit and normal versus overweight/obese. Medicare claims data were used to obtain all-cause dementia incidence (1999-2009). Mean follow-up between midlife examinations and Medicare surveillance was 15.7 ((SD=6.2) years. Multivariable models were used to assess the associations between fitness, BMI and dementia. RESULTS: During 40 773 person years of Medicare surveillance, 632 cases of dementia were identified. After controlling for BMI and covariates, each 1-metabolic equivalent increment in fitness was associated with 5% lower (HR 0.95; 95% CI 0.90 to 0.99) dementia risk. In comparison, after controlling for fitness and covariates, each 1 kg/m2 increment in BMI was associated with a 3.0% (HR 1.03; 95% CI 1.00 to 1.07) higher risk for dementia, yet without significance (p=0.051). Similar findings were observed when the exposures were categorised. Changes in fitness and BMI between examinations were not related to dementia. Jointly, participants who were unfit and overweight/obese had the highest (HR 2.28 95% CI 1.57 to 3.32) dementia risk compared with their fit and normal weight counterparts. CONCLUSION: Lower midlife fitness is a risk marker for dementia irrespective of weight status. Being unfit coupled with overweight/obese status might increase one's risk for dementia even further.

The yield of early-pregnancy homeostasis of model assessment -insulin resistance (HOMA-IR) for predicting gestational diabetes mellitus in different body mass index and age groups.

BACKGROUND: Early prediction of gestational diabetes mellitus(GDM) can be beneficial for lifestyle modifications to prevent GDM. The aim of this study was to investigate the predictive values of Homeostasis of Model Assessment -Insulin Resistance (HOMA-IR) in early pregnancy to predict GDM development in different body mass index (BMI) and age risk categories. MATERIALS AND METHODS: This study is part of the Qazvin Maternal and Neonatal Metabolic Study (QMNMS) in Iran (2018-2021). In this prospective longitudinal study, pregnant women with a gestational age ≤ 14 weeks were enrolled in the study using convenience sampling method and were followed up until delivery to investigate risk factors for maternal and neonatal complications. Data collection was done using questionnaires. Serum sampling was done at a gestational age ≤ 14 weeks and sera were frozen until the end of study. GDM was diagnosed at 24-28 weeks of pregnancy using 75gr oral glucose tolerance test. Fasting blood glucose and insulin were measured in sera taken during early pregnancy in 583 participants. The Mann-Whitney U test, independent t-test, and Chi-square test were used for comparing variables between groups. The logistic regression analysis was used to examine the independent association of HOMA-IR with GDM development and receiver operating characteristic analysis was used for finding the best cut-off of HOMA-IR for predicting GDM. RESULTS: GDM was developed in 90 (15.4%) of the participants. The third HOMA-IR tertile was independently associated with 3.2 times higher GDM occurrence (95% CI:1.6-6.2, P = 0.001). Despite the high prevalence of GDM in advanced maternal age (GDM rate = 28.4%), HOMA-IR had no association with GDM occurrence in this high-risk group. In both normal BMI and overweight/obese groups, HOMA-IR was a moderate predictor of GDM development (AUC = 0.638, P = 0.005 and AUC = 0.622, P = 0.008, respectively). However, the best cut-off for predicting GDM was 2.06 (sensitivity 67.5%, specificity 61.1%) in normal BMI and 3.13 (sensitivity 64.6%, specificity61.8%) in overweight/obese BMI. CONCLUSION: The present study revealed the necessity of considering the BMI and age risk groups when using the HOMA-IR index to predict GDM. Using lower cut-offs is more accurate for women with a normal BMI. In the advanced maternal age, there is no yield of HOMA-IR for predicting GDM.

Behavioral and metabolic risk factors associated with periodontitis in Brazil, 1990-2019: a multidimensional analysis for the Global Burden of Disease Study 2019.

OBJECTIVES: Periodontitis is a non-communicable disease (NCD) that may be linked to other NCDs through shared risk factors. Accordingly, we analyzed the relationship between periodontitis and behavioral and metabolic risks common to NCDs in Brazilian adults over three decades. METHODS: Indicators of periodontitis, behavioral risks (smoking, alcohol use, sugar-sweetened beverages (SSB), and physical activity), and metabolic risks (overweight/obesity, dyslipidemia, hyperglycemia, and hypertension) in Brazilian adults (25-49 y-old) between 1990 to 2019 were obtained from the Global Burden of Disease Study 2019. Data were adjusted for Gini index. Fixed-effects and Prais-Winsten regressions were performed (p < 0.05). RESULTS: The prevalence of periodontitis has increased among Brazilians since 2005. High-SSB diet, alcohol use, and metabolic risks increased between 1990-2019, whereas smoking decreased. In crude models, periodontitis prevalence increased with alcohol use (2545.1; 95%CI: 2307.9-2782.3), high-SSB diet (365.5; 95%CI: 322.5-408.4), low physical activity (1784.4; 95%CI: 763.7-2805.0), overweight/obesity (172.3; 95%CI: 156.3-188.4), dyslipidemia (734.5; 95%CI: 624.7-844.2), and hyperglycemia (1774.3; 95%CI: 1555.9-1992.7). After adjustment for the Gini index, periodontitis prevalence raised with a high-SBB diet (1416.0; 95%CI: 1120.2-1711.8), overweight/obesity (629.9; 95%CI: 573.1-686.8), dyslipidemia (2035.8; 95%CI: 1728.1-2343.5), and hyperglycemia (8918.1; 95%CI: 7979.8-9856.3). CONCLUSIONS: Periodontitis has increased in Brazil since 2005, despite the smoking reduction. Sugar-sweetened beverage was the behavioral risk that mostly accompanied the periodontal trend. CLINICAL RELEVANCE: Our results support upstream strategies targeting commercial, social, political, and structural determinants to tackle NCDs and reduce oral health inequities.

Breast cancer survivors with pain: an examination of the relationships between body mass index, physical activity, and symptom burden.

PURPOSE: Overweight and obesity are common for breast cancer survivors and associated with high symptom burden (i.e., pain, fatigue, depressive symptoms). Physical activity may protect breast cancer survivors with higher body mass indexes (BMI) from increased symptoms. However, the role of physical activity in buffering the relationship between higher BMI and greater symptoms is unclear. METHODS: Baseline data from a randomized trial investigating Pain Coping Skills Training among breast cancer survivors (N = 327) with pain were used to examine the relationship between self-reported BMI (kg/m2) and physical activity level (Rapid Assessment of Physical Activity; suboptimal vs. optimal) with pain (Brief Pain Inventory; severity and interference), fatigue (PROMIS-Fatigue short form), and depressive symptoms (Center for Epidemiological Studies Depression Scale). Analyses were conducted in SPSS. Hayes PROCESS macro (Model 1) assessed whether physical activity moderated the relationship between BMI and symptoms. RESULTS: Lower BMI (B = .06, p < .01) and optimal physical activity (B = - .69, p < .01) were independently associated with lower pain interference. Lower BMI was also associated with lower pain severity (B = .04, p < .001). Neither BMI nor physical activity was associated with fatigue or depressive symptoms. Physical activity did not moderate the relationship between BMI and symptoms. CONCLUSIONS: Among breast cancer survivors experiencing pain, higher BMI and being less physically active were related to greater pain (i.e., severity and/or interference). Physical activity did not buffer the relationships between BMI and pain, fatigue, and depressive symptoms, suggesting that physical activity alone may not be sufficient to influence the strength of the relationships between BMI and symptoms.

Gestational weight change in a diverse pregnancy cohort and mortality over 50 years: a prospective observational cohort study.

BACKGROUND: High weight gain in pregnancy is associated with greater postpartum weight retention, yet long-term implications remain unknown. We aimed to assess whether gestational weight change was associated with mortality more than 50 years later. METHODS: The Collaborative Perinatal Project (CPP) was a prospective US pregnancy cohort (1959-65). The CPP Mortality Linkage Study linked CPP participants to the National Death Index and Social Security Death Master File for vital status to 2016. Adjusted hazard ratios (HRs) with 95% CIs estimated associations between gestational weight gain and loss according to the 2009 National Academy of Medicine recommendations and mortality by pre-pregnancy BMI. The primary endpoint was all-cause mortality. Secondary endpoints included cardiovascular and diabetes underlying causes of mortality. FINDINGS: Among 46 042 participants, 20 839 (45·3%) self-identified as Black and 21 287 (46·2%) as White. Median follow-up time was 52 years (IQR 45-54) and 17 901 (38·9%) participants died. For those who were underweight before pregnancy (BMI <18·5 kg/m2; 3809 [9·4%] of 40 689 before imputation for missing data]), weight change above recommendations was associated with increased cardiovascular mortality (HR 1·84 [95% CI 1·08-3·12]) but not all-cause mortality (1·14 [0·86-1·51]) or diabetes-related mortality (0·90 [0·13-6·35]). For those with a normal pre-pregnancy weight (BMI 18·5-24·9 kg/m2; 27 921 [68·6%]), weight change above recommendations was associated with increased all-cause (HR 1·09 [1·01-1·18]) and cardiovascular (1·20 [1·04-1·37]) mortality, but not diabetes-related mortality (0·95 [0·61-1·47]). For those who were overweight pre-pregnancy (BMI 25·0-29·9 kg/m2; 6251 [15·4%]), weight change above recommendations was associated with elevated all-cause (1·12 [1·01-1·24]) and diabetes-related (1·77 [1·23-2·54]) mortality, but not cardiovascular (1·12 [0·94-1·33]) mortality. For those with pre-pregnancy obesity (≥30·0 kg/m2; 2708 [6·7%]), all associations between gestational weight change and mortality had wide CIs and no meaningful relationships could be drawn. Weight change below recommended levels was associated only with a reduced diabetes-related mortality (0·62 [0·48-0·79]) in people with normal pre-pregnancy weight. INTERPRETATION: This study's novel findings support the importance of achieving healthy gestational weight gain within recommendations, adding that the implications might extend beyond the pregnancy window to long-term health, including cardiovascular and diabetes-related mortality.

[Risk factors for disability in patients with stroke in northeastern Mexico: A retrospective cross-sectional study]. / Factores de riesgo para discapacidad en pacientes con accidente cerebrovascular en el noreste de México: estudio retrospectivo transversal.

OBJECTIVE: To determine the risk factors associated with disability in patients who had a stroke in northeastern Mexico. DESIGN: This was an observational, retrospective, cross-sectional study. SITE: Conducted at the Family Medicine Unit No. 33 of the Mexican Institute of Social Security in Reynosa, Tamaulipas, Mexico. PARTICIPANTS: One hundred and ninety-eight males and 146 females, above 18 years old, beneficiaries of the Mexican Institute of Social Security with a diagnosis of stroke between 2018 and 2021. INTERVENTIONS: The Barthel index that assesses the degree of dependence to perform basic activities of daily living was applied to the participants and sociodemographic, biological and anthropometric variables were collected from the digital medical record. MAIN MEASURES: A univariate, correlational and ordinal logistic regression statistical analysis was performed between independent and dependent variables to obtain measures of frequency, percentages, and associated risks. RESULTS: The risk factors associated with disability were age (OR 1.03, CI 1.01-1.05), overweight (OR 1.81, CI 1.03-3.1), obesity grade I (OR 2.74, CI 1.46-5.1), obesity grade II (OR 4.38, CI 1.44-13), obesity grade III (OR 9.99, CI 2.12-47); type of stroke: ischemic (OR 4.60, CI 2.6-8) or thrombotic (OR 4.95, CI 1.57-15). The number of comorbidities was associated with disability when having one comorbidity (OR 2.80, CI 1.22-6.4), two comorbidities (OR 3.43, CI 1.37-8.5), three comorbidities (OR 2.71, CI 1.01-7.3), and with five comorbidities (OR 3.17, CI 1.01-9.9). CONCLUSIONS: The risk factors found for disability were age, overweight, obesity, and type of ischemic and thrombotic stroke. Being cared for by a relative and/or spouse reduces the probability of disability.

Assessment of nutritional status using anthropometric index among older adult and elderly population in India.

Malnutrition poses a significant risk to the older population globally, highlighting the critical role of nutrition in healthy aging. In this study, the aim is to estimate the prevalence of malnutrition among older adults aged 45-59 years and the elderly population aged 60 years and above based on their socioeconomic and demographic characteristics. Furthermore, the study examines the risk factors within a multivariate framework. A sample of 59,073 individuals aged 45 years and above from the Longitudinal Aging Study in India (LASI), Wave 1 survey constitutes the study population. This study adopts a cross-sectional design. Bivariate cross-tabulation analysis and multivariate logistic regression analysis are employed to understand the prevalence and determinants of nutritional status. About 25% of males and 37% of females below the age of 60 years are overweight (including obese), while among those aged 60 years and above, 28% of males and 25% of females are underweight. The elderly male population carries a comparatively higher burden of underweight (28%) prevalence than the females (25%) in the same age group. Overall, the urban population is less likely to be underweight [AOR: 0.41, C.I 0.38-0.43] and more likely to be overweight [AOR: 2.41, C.I 2.32-2.52]. Older adults from low economic and social strata are more likely to be underweight. In terms of bio-physical factors, individuals aged 60 years and above with infections to endemic diseases [AOR: 1.24; p-value < 0.01] and those with edentulism [AOR: 1.29; p-value < 0.01] are more likely to be underweight. As evident from the study, nutritional status among older adults is a complicated manifestation of multiple risk factors and requires potential nutritional intervention. Initiating a routine screening program at the grassroots level can effectively identify older adults and the elderly in India, facilitating the provision of nutritional care.

[Use of cinacalcet in secondary hyperparathyroidism: assessment of nutritional, lipid and inflammatory status in chronic kidney disease]. / Uso de cinacalcet en hiperparatiroidismo secundario: evaluación del estado nutricional, lipídico e inflamatorio en enfermedad renal crónica.

Introduction: Introduction: observations in cell lines suggest that the use of cinacalcet could be associated with increase in body fat, inflammatory state, and alteration in lipid metabolism. However, when scaling the model to the clinical level, the occurrence of these effects is unknown. Objectives: to analyze the effect of cinacalcet therapy on anthropometric, inflammatory and lipid parameters in renal patients with secondary hyperparathyroidism (SHPT). Methods: observational study with two approaches. The retrospective study included 89 patients who started cinacalcet treatment since 2018 with a maximum follow-up of 36 months. Body mass index (BMI) variables, waist circumference, tricipital skinfold, parathyroid hormone (PTH), and biochemical profile were analyzed. The prospective study included 52 patients who started cinacalcet treatment since 2020 with a 12-month follow-up. BMI, PTH, lipid profile, and PCR variables were analyzed. Results: in the retrospective study, BMI was 27 kg/m2, with 62 % overweight and 65 % of patients with high cardiovascular risk. Cinacalcet reduced PTH by 12 % after six months (p < 0.01) and serum calcium decreased by 3.4 % at the end of follow-up (p = 0.04). According to the prospective study, BMI was 26.8 kg/m2, with 60 % overweight. PTH decreased by 8.4 % after six months. Total cholesterol, LDL cholesterol, and triglycerides decreased by 6.8 %, 12.5 %, and 5.5 %, respectively, at the end of follow-up. Conclusions: the prevalent nutritional status is excess weight. In patients with SHPT, cinacalcet improves PTH control without causing changes in anthropometric, lipid, and inflammatory parameters.

Introducción: Introducción: observaciones en líneas celulares sugieren que el uso de cinacalcet podría asociarse con un aumento de grasa corporal y del estado inflamatorio y una alteración del metabolismo lipídico. Sin embargo, al escalar el modelo a nivel clínico se desconoce la ocurrencia de estos efectos. Objetivos: analizar el efecto de la terapia con cinacalcet sobre parámetros antropométricos, inflamatorios y lipídicos en pacientes renales con hiperparatiroidismo secundario (HPT2). Métodos: estudio observacional con dos aproximaciones. El estudio retrospectivo incluyó 89 pacientes que iniciaron tratamiento de cinacalcet desde el año 2018 con un seguimiento máximo de 36 meses. Se analizaron variables de índice de masa corporal (IMC), circunferencia de cintura, pliegue tricipital, paratohormona (PTH) y perfil bioquímico. El estudio prospectivo incluyó 52 pacientes que iniciaron tratamiento con cinacalcet desde el año 2020 con un seguimiento de 12 meses. Se analizaron variables de IMC, PTH, perfil lipídico y proteína C reactiva (PCR). Resultados: en el estudio retrospectivo, el IMC fue de 27 kg/m2, con un 62 % de exceso de peso y un 65 % de los pacientes con riesgo cardiovascular elevado. Cinacalcet redujo la PTH un 12 % luego de seis meses (p < 0,01) y el calcio sérico disminuyó un 3,4 % al final del seguimiento (p = 0,04). En el estudio prospectivo, el IMC fue de 26,8 kg/m2, con un 60 % de exceso de peso. La PTH disminuyó un 8,4 % luego de seis meses. El colesterol total, el colesterol LDL y los triglicéridos disminuyeron en un 6,8 %, 12,5 % y 5,5 %, respectivamente, al finalizar el seguimiento. Conclusiones: el estado nutricional prevalente es el exceso de peso. En pacientes con HPT2 cinacalcet mejora el control de la PTH sin provocar cambios en parámetros antropométricos, lipídicos e inflamatorios.

Effect of being overweight and obese on periodontal treatment costs.

BACKGROUND: Obesity can increase a person's risk of developing periodontal disease, and patients with obesity have greater health care costs. However, the effect of obesity on periodontal treatment costs has not been examined. METHODS: This retrospective cohort study used data from the electronic dental records of adult patients examined from July 1, 2010, through July 31, 2019 at a US dental school. Primary exposure was body mass index, which was categorized as obese, overweight, or normal. Periodontal disease was categorized using clinical probing measures. Fee schedules and procedure codes were used to compute the primary outcome, which was total periodontal treatment costs. A generalized linear model with gamma distribution was used to examine the relationship between body mass index and periodontal costs after controlling for initial periodontal disease severity and other confounding variables. Parameter coefficients and mean ratios with 95% CIs were estimated. RESULTS: The study sample included 3,443 adults, of whom 39% were normal weight, 37% were overweight, and 24% were obese. Mean (SD) total periodontal treatment costs for patients who were obese were considerably higher ($420 [$719]) than those for patients who were overweight ($402 [$761]) and patients who were normal weight ($268 [$601]). After controlling for covariates and disease severity, patients who were obese had 27% higher periodontal treatment costs than patients who were normal weight. The additional periodontal treatment costs attributable to obesity were greater than those attributable to either diabetes or smoking. CONCLUSIONS: The study results suggest that among patients at a dental school, those who were obese incurred substantially higher periodontal treatment costs than patients who were normal weight, independent of initial periodontal disease severity. PRACTICAL IMPLICATIONS: The study findings have important implications for clinical guidelines and dental benefit design and coverage policies.

Population-attributable risk of modifiable lifestyle factors to hepatocellular carcinoma: The multi-ethnic cohort.

BACKGROUND AND AIMS: Lifestyle factors are well associated with risk of hepatocellular carcinoma (HCC). However, the impact of reducing adverse lifestyle behaviours on population-level burden of HCC is uncertain. METHODS: We conducted prospective analysis of the population-based multi-ethnic cohort (MEC) with linkage to cancer registries. The association of lifestyle factors (smoking, alcohol, diet quality assessed by alternate Mediterranean diet score, coffee drinking, physical activity and body mass index) with HCC incidence was examined using Cox regression. Population-attributable risk (PAR, %) for the overall, lean and overweight/obese populations was determined. RESULTS: A total of 753 incident cases of HCC were identified in 181,346 participants over median follow-up of 23.1 years. Lifestyle factors associated with elevated HCC risk included former/current smoking, heavy alcohol use, poor diet quality, lower coffee intake and obesity, but not physical activity. The lifestyle factor with highest PAR was lower coffee intake (21.3%; 95% CI: 8.9%-33.0%), followed by current smoking (15.1%; 11.1%-19.0%), obesity (14.5%; 9.2%-19.8%), heavy alcohol use (7.1%; 3.5%-10.6%) and lower diet quality (4.1%; 0.1%-8.1%). The combined PAR of all high-risk lifestyle factors was 51.9% (95% CI: 30.1%-68.6%). A higher combined PAR was observed among lean (65.2%, 26.8%-85.7%) compared to overweight/obese (37.4%, 11.7%-58.3%) participants. Adjusting for viral hepatitis status in a linked MEC-Medicare dataset resulted in similar PAR results. CONCLUSIONS: Modifying lifestyle factors, particularly coffee intake, may have a substantial impact on HCC burden in diverse populations, with greater impact among lean adults. Diet and lifestyle counselling should be incorporated into HCC prevention strategies.

The burden of disease and economic impact of sugar-sweetened beverages' consumption in Argentina: A modeling study.

BACKGROUND: Approximately two-thirds of Argentine adults are overweight or obese, and 11% have diabetes. Over the last two decades, all population groups have increased their consumption of ultra-processed foods and sugar-sweetened beverages (SSB). We aimed to estimate the disease burden-deaths, events, and costs to the health system-attributed to SSB consumption in Argentina. METHODS: We used a comparative risk assessment framework to estimate the health and economic impacts that would be avoided in a scenario without sugar-sweetened beverage (SSB) consumption. We calculated the direct effects on diabetes, cardiovascular disease, and BMI, and then estimated the effects of BMI on disease incidence. Finally, we applied the population attributable factor to calculate the health and economic burden avoided in Argentina in 2020. RESULTS: Our model estimated that about 4,425 deaths, 110,000 healthy life years lost to premature death and disability, more than 520,000 cases of overweight and obesity in adults, and 774,000 in children and adolescents would be attributed to SSB Consumption in Argentina. This disease burden corresponds to 23% of type-2 diabetes cases and other significant proportions of cardiovascular disease and cancer. The overweight and obesity costs attributable to SSB totaled approximately $47 million in adults and $15 million in children and adolescents. CONCLUSION: A significant number of disease cases, deaths, and health care costs could be attributed to SSB consumption in Argentina. Implementing measures to reduce the sugar content in beverages is a pending debt for the country and could lead to measurable improvements in population health, especially among children and adolescents.

Risk assessment of postoperative pneumonia in children with neurologic disorders and obesity.

INTRODUCTION: Postoperative pneumonia increases the risk of postsurgical mortality, making it a serious healthcare-associated complication. Children with preoperative neuromuscular impairments have a higher risk of postoperative pneumonia. Obesity is also a risk factor for postoperative pulmonary complications, including pneumonia. Moreover, obesity is increasingly prevalent among children living with a neurological diagnosis. Whether obesity increases the risk of postoperative pneumonia among children with neurologic diseases remains largely unknown. Therefore, we assessed the risk of postoperative pneumonia among children with neurologic diagnoses based on their obesity status. METHODS: We analyzed a retrospective cohort of children ≤18 years from the National Surgical Quality Improvement Program (2012-2019) database who underwent inpatient orthopedic surgery. We used Cox proportional regression model to estimate the hazard ratio for the association between neurologic disorders and postoperative pneumonia. In addition, we included an interaction term between body mass index and neurologic disorders to evaluate the moderating effect of obesity status and then performed stratified analyses to compare the magnitude of hazard ratios across body mass index subgroups. RESULTS: A total of 60 745 children underwent inpatient orthopedic surgery during the study period, of whom 43.6% were healthy weight and 30.8% overweight/obese. The median age was 13 years (Interquartile range: 8-15). The incidence of postoperative pneumonia was higher among healthy weight patients with neurologic disorders than healthy weight patients without any neurologic disorders [Hazard ratio: 3.55 vs. 0.34]. Furthermore, the association between neurologic disorders and postoperative pneumonia was strongest among overweight patients than healthy weight or obese patients [Hazard ratio:11.88 vs. 9.45 vs. 4.40]. This observation was consistent across the various neurologic disorders analyzed. CONCLUSION: Childhood obesity buffered the association between neurologic disorders and postoperative pneumonia, consistent with an 'obesity paradox'. Further research exploring the underlying mechanisms for the obesity paradox in children with neurologic disorders is warranted.

Twelve-Year Trajectory of Disease Burden and Mortality by Obesity Level in Korea: Analysis of the National Health Insurance Service Database.

INTRODUCTION: Despite increases in obesity prevalence, awareness of obesity as a disease requiring active treatment remains lacking in Korea. We investigated differences in medical problems and expenditures and mortality across obesity categories using 12-year data from the National Health Insurance Service. MATERIALS AND METHODS: Individuals aged 40-79 years who underwent medical examinations during 2003-2004 (n = 415,201) were divided based on Asian body mass index (kg/m2) criteria: normal weight (18.5 to < 23.0, 36.4%), overweight (23.0 to < 25.0, 28.3%), obesity (25.0 to < 30.0, 32.5%), and severe obesity (≥ 30.0, 2.8%). Medical problems and expenditures were fitted to linear mixed models. Mortality was analyzed via Cox proportional-hazards model. RESULTS: More severe obesity was associated with a higher rate of medical problems, relative to normal weight: coefficient = 0.31 (95% confidence interval [CI], 0.30-0.32) for overweight, 0.61 (0.60-0.61) for obesity, and 1.07 (1.04-1.09) for severe obesity. A similar association was observed for medical expenditure: coefficient = 8.85 (95%CI, 6.80-10.89) for overweight, 20.04 (18.07-22.01) for obesity, and 48.76 (43.66-53.86) for severe obesity. Relative to overweight participants, those with normal weight and severe obesity exhibited a higher mortality risk (hazard ratio [HR] 1.21 [95%CI, 1.18-1.25] for normal; 1.27 [1.19-1.36] for severe obesity). In age-specific analyses, mortality risk was the highest for participants with severe obesity, aged < 60 years (HR, 1.58 [95%CI, 1.41-1.77]). CONCLUSION: Disease burden including medical problems and expenditure, and mortality in middle-aged adults, increased proportionally to the degrees of obesity. Health policies and medical systems aimed at reducing the burden of obesity may help reduce the burden of disease on society.

Obesity in pregnancy in a resource-constrained setting: Complications and cost implications - a retrospective cross-sectional study.

OBJECTIVE: To investigate the complications and costs associated with managing obese pregnant women in a resource-constrained environment. METHODS: The files were randomly sampled for women that delivered at the tertiary level public sector Greys Hospital in Pietermaritzburg, South Africa; of the retrieved files, 206 met the inclusion criteria (January-June 2020). Patients were stratified by body mass index (normal, overweight, obese). The main outcomes being the prevalence of obesity, we conducted a logistic regression to compare the incidence of associated obstetric complications, and a direct costs comparison. RESULTS: Of the 206 patients, 117 (57%) were obese and at higher risk for fetal and maternal adverse outcomes. The obese/overweight group had higher incidence of pre-pregnancy complications; history of macrosomia and obstetric complications; and increased risk of failed induction, fetal anomalies, unscheduled prenatal care visits, and postpartum hemorrhage. Neonates born to obese/overweight women were at increased need for neonatal unit admission. The mean cost estimates were 49575.3 South African Rand (ZAR) for normal weight, 49310.5 ZAR for overweight, and 54444.2 ZAR for obese women. CONCLUSION: The high levels of obesity were associated with feto-maternal complications; the association increased healthcare use, resulting in a substantial increase in direct cost to the healthcare system.

Cost-Effectiveness of Earlier or More Intensive Colorectal Cancer Screening in Overweight and Obese Patients.

BACKGROUND & AIMS: Overweight and obese persons have not only elevated rates of colorectal cancer (CRC), but also higher competing mortality and healthcare spending. We examined the cost-effectiveness of intensified CRC screening in overweight and obese persons. METHODS: We adapted our validated decision analytic model of CRC screening to compare screening starting at 45 or 40 years of age instead of at 50 years of age, or shortening screening intervals, in women and men with body mass index (BMI) ranging from normal to grade III obesity. Strategies included colonoscopy every 10 years (Colo10) or every 5 years (Colo5), or annual fecal immunochemical test. RESULTS: Without screening, sex-specific total CRC deaths were similar for persons with overweight or obesity I-III, reflecting the counterbalancing of higher CRC risk by lower life expectancy as BMI rises. For all BMI and sex groups, Colo10 starting at 45 years of age or FIT starting at 40 years of age were cost-effective at a threshold of $100,000 per quality-adjusted life year gained. Colo10 starting at 40 years of age was cost-effective only for men with obesity II-III, at $93,300 and $80,400 per quality-adjusted life year gained, respectively. Shifting Colo10 to earlier starting ages was always preferred over Colo5 starting at later ages. Results were robust in sensitivity analysis, including varying all-cause mortality, complication, and BMI-specific CRC risks. CONCLUSIONS: CRC screening starting at 45 years of age with colonoscopy, or at 40 years of age with FIT, appears cost-effective for women and men across the range of BMI. In men with obesity II-III, who have the highest CRC but also all-cause mortality risks, colonoscopy starting at 40 years of age appears cost-effective. It remains to be decided whether BMI should be used as a single predictor or incorporated into a multivariable tool to tailor CRC screening.

Cost-Effectiveness of Telehealth-Delivered Exercise and Dietary Weight Loss Programs for Knee Osteoarthritis Within a Twelve-Month Randomized Trial.

OBJECTIVE: To evaluate the cost-effectiveness of telehealth-delivered exercise and diet-plus-exercise programs within 12 months. METHODS: An economic evaluation within a 12-month, 3-arm, parallel randomized trial of two 6-month telehealth-delivered exercise programs, with and without a dietary component. A total of 415 people with knee osteoarthritis ages 45-80 years and body mass index of 28-40 kg/m2 were assigned to 1 of 2 telehealth-delivered exercise programs, 1 without (n = 172) and 1 with (n = 175) a dietary component (ketogenic very low calorie diet), or to an education control (n = 67), for 6 months, with 6 months follow-up. The primary economic outcomes were quality-adjusted life years (QALYs) and health system costs. Measured costs were the direct intervention (consultations, equipment/resources, and meal replacements) and health care use in 2020 Australian dollars ($AU1.5 = $US1). Secondary analysis included weight loss and work productivity gains. RESULTS: The clinical trial demonstrated greater improvements in pain and function compared to information only for individuals with knee osteoarthritis and overweight/obesity. We can be 88% confident that diet plus exercise is cost effective ($45,500 per QALY), 53% confident that exercise is cost-effective ($67,600 per QALY) compared to the control, and 86% confident that augmenting exercise with the diet program is cost effective ($21,100 per QALY). CONCLUSION: Telehealth-delivered programs targeting exercise with dietary intervention for people with knee osteoarthritis who have overweight/obesity are likely to be cost-effective, particularly if potential long-term gains from weight loss and work productivity are realized.

Obesity and metabolic state are associated with increased healthcare resource and medication use and costs: a Finnish population-based study.

AIM: To characterize healthcare resource (HCRU) and medication use and associated costs in individuals with obesity compared with individuals with normal weight or overweight in a population-based cohort of Finnish adults. The association between metabolic state and direct costs was also assessed. METHODS: The study cohort included 5587 randomly selected individuals who participated in the national FinHealth 2017 health examination survey. Data on healthcare visits and hospital stays, including diagnoses (ICD-10), and purchases and costs of prescription medicines were collected from the nationwide registers by the Finnish Institute for Health and Welfare and Social Insurance Institution of Finland. The healthcare costs were calculated based on standard unit costs reported by the Finnish Institute for Health and Welfare. RESULTS: The total annual direct costs were €2665 (SD €5673) and €1799 (SD €3874) per person with obesity and with normal weight or overweight, respectively. Obesity was associated with significantly increased total direct (age- and sex-adjusted cost rate ratio, RR, 1.356; p < 0.001), HCRU-related (1.273; p = 0.002), and medication (1.669; p < 0.001) costs. A vast majority (90%) of individuals with obesity were classified as metabolically unhealthy based on clinical measurements. The metabolically unhealthy state was associated with increased costs in individuals with obesity but not in individuals with normal weight or overweight. CONCLUSION: Obesity is associated with a significant and complex direct cost burden to society, arising primarily from increased comorbidity. Metabolically healthy obesity is uncommon and obesity prevention and timely treatment should be of high priority to tackle the increasing burden of obesity.

Assessment of Cardiorespiratory Fitness in 8-to-15-Year-Old Children with Overweight/Obesity by Three-Minute Step Test: Association with Degree of Obesity, Blood Pressure, and Insulin Resistance.

OBJECTIVE: To assess cardiorespiratory fitness in children and adolescents with overweight/obesity using the Kasch pulse recovery (KPR) test, and its correlation with severity of obesity, insulin resistance, and blood pressure (BP). METHODS: This is a retrospective analysis of baseline data from a study evaluating the efficacy of yoga for reduction of body mass index (BMI) in children aged 8-15 y with overweight/obesity. KPR three-minute step test was done. Children were classified into cardiorespiratory fitness categories based on the post-KPR heart rate (HR); the maximal oxygen consumption (VO2 max) was calculated, and the correlation analysis was done. RESULTS: One hundred fifty-five children with mean age of 11.6 ± 1.8 y and mean BMI of 26.2 ± 4.1 kg/m2 were included. Mean post-KPR-HR and calculated VO2 max were 119 ± 14 per minute and 48.7 ± 5.6 mL/kg/min, respectively. In children < 13 y, cardiorespiratory fitness was excellent or very good in 28%, good or sufficient in 58%, and poor or very poor in 14%. BMI, waist circumference (WC), resting HR, systolic BP, and homeostatic model of insulin resistance (HOMA-IR) were higher among those with poor/very poor fitness, with WC z score being statistically significant (p = 0.015). Post-KPR-HR showed positive correlation with BMI z score (r = 0.16, p = 0.044), WC z score (r = 0.21, p = 0.011), and HOMA-IR (r = 0.22, p = 0.012). CONCLUSION: In children with overweight/obesity, 14% had poor cardiorespiratory fitness. Post-KPR-HR and calculated VO2 max had good correlation with measures of obesity and HOMA-IR. Further studies evaluating cardiorespiratory fitness and normative data of VO2 max for Indian children are warranted.
