Health economic evaluation of weight reduction interventions in individuals suffering from overweight or obesity and a musculoskeletal diagnosis-a systematic review.

BACKGROUND: Most of the worldwide population is overweight and suffers from the resulting musculoskeletal comorbidities such as knee osteoarthritis or back pain. Practice guidelines recommend weight loss interventions for individuals suffering from these conditions. This systematic review investigated whether including a weight loss intervention in the musculoskeletal therapy of these individuals was cost-effective compared to administering the musculoskeletal therapy alone. METHODS: This study followed the PRISMA guidelines to systematically and independently search six databases and select full health economic evaluations published up to May 2024 from health care or societal perspectives according to predefined eligibility criteria. Cost data were standardised to 2023 Belgium Euros. The methodological quality was assessed using two health economic-specific checklists. RESULTS: The searches produced 5'305 references, of which 8 studies were selected for a total of 1'726 participants. The interventions consisted of different exercise plans and nutritional targets. Six values were in the north-eastern; leading to increased quality-adjusted life year (QALY) and higher costs; and two in the south-eastern quadrant of the cost-utility plane; leading to increased QALYs and lower costs. Two studies observed no differences in QALYs. Incremental cost utility ratios (ICUR) ranged from €13'580.10 to €34'412.40 per additional QALY from a healthcare perspective. From a societal perspective, the ICUR was €30'274.84. The included studies fulfilled 86 percent of the criteria in trial-based economic evaluations and 57 percent in model-based economic evaluations. The most common limitations of the studies were related to appropriate cost measures' specifications, research questions, time horizon choices, and sensitivity analyses. CONCLUSIONS: This systematic review showed weak but consistent evidence of cost-effectiveness for adding a weight loss intervention to musculoskeletal therapy for individuals with overweight, from either perspective. Further economic evaluations should evaluate the long-term cost-effectiveness of the intervention.

The Return on Investment for the Prevention and Treatment of Childhood and Adolescent Overweight and Obesity in Beijing: A Modeling Study.

Background: The increasing prevalence of child and adolescent overweight and obesity (CAOAO) in Beijing poses significant health and economic challenges. This study assesses the potential health and economic outcomes of implementing specific interventions to address CAOAO in Beijing. Methods: A deterministic Markov cohort model was used to estimate the impact of five interventions from 2025 to 2115: restrictions on unhealthy food marketing to children, mandatory front of package labeling (FOPL), family-based nutrition and exercise education, school-based nutritional health education, and nutritional counseling in primary healthcare. The model evaluated societal costs, healthcare savings, wages, and economic productivity in adulthood, calculating the return on investment (ROI) for each intervention and their combined effect. Result: Without intervention, Beijing is projected to experience a loss of 13.4 million disability-adjusted life years (DALYs) due to CAOAO. The health and economic impact of childhood obesity in Beijing is projected to be CNY 14.6 trillion (USD 2.1 trillion), or a lifetime loss of CNY 6.8 million (USD 0.96 million) per affected child, exceeding the sum of Beijing's GDP from 2021 to 2023. Restrictions on unhealthy food marketing to children and nutrition counseling in primary healthcare are projected to yield the highest returns, with benefits accruing within one year of implementation. Owing to the substantial upfront costs, including personnel, materials, and training, school-based and family-based interventions require a longer time horizon to realize significant health and economic benefits. Conclusions: Effective management of CAOAO in Beijing demands a multifaceted approach. The combination of restrictions on unhealthy food marketing to children, mandatory front of package labeling, nutrition counseling in primary healthcare, school-based intervention, and family-based intervention presents the most substantial health and economic returns. This comprehensive strategy aligns with global best practices and addresses the unique challenges faced by Beijing in combating childhood obesity.

Taking a health economic perspective in monitoring health inequalities: A focus on excess weight.

BACKGROUND: Traditional approaches to monitoring health inequalities predominantly rely on headcount methods. However, these methods fail to reflect the non-linear health economic implications of changes in disease severity. Alternative, distribution-sensitive metrics are available which could more adequately inform financial planning and policy decision making. METHODS: We describe the design of the Foster-Greer-Thorbecke (FGT) index, and discuss its relative merits as a summary monitoring metric of health inequalities in the population, compared to the Erreygers concentration index. We illustrate the FGT index by conducting a comparative longitudinal analysis of adult excess inequalities in England using Health Survey for England data from 2009 to 2019. FINDINGS: Excess weight inequalities have steadily increased in the English adult population, especially over the last five years. Going beyond headcount, the FGT index analyses revealed that, unlike the rest of the population, the average overweight adult from the most socio-economically deprived group is either obese (30.3 BMI for females) or at the brink of obesity (29.1 BMI for males). These results underscore a deepening divide in obesity severity between communities, with the most socioeconomically deprived groups being increasingly and disproportionally affected. CONCLUSIONS: The FGT index can address some shortcomings of traditional approaches to inequality measurement and local governments should consider adopting it as an alternative population health metric. Future research should apply and develop more refined distribution-sensitive measures of health inequality.

Cost-effectiveness of a primary care-based Healthy Weight Clinic compared with usual care.

OBJECTIVE: The objective of this study was to project the cost-effectiveness of implementing the Healthy Weight Clinic (HWC), a primary care-based intervention for 6- to 12-year-old children with overweight or obesity, at federally qualified health centers (FQHCs) nationally. METHODS: We estimated intervention costs from a health care sector and societal perspective and used BMI change estimates from the HWC trial. Our microsimulation of national HWC implementation among all FQHCs from 2023 to 2032 estimated cost per child and per quality-adjusted life year (QALY) gained and projected impact on obesity prevalence by race and ethnicity. Probabilistic sensitivity analyses assessed uncertainty around estimates. RESULTS: National implementation is projected to reach 888,000 children over 10 years, with a mean intervention cost of $456 (95% uncertainty interval [UI]: $409-$506) per child to the health care sector and $211 (95% UI: $175-$251) to families (e.g., time participating). Assuming effect maintenance, national implementation could result in 2070 (95% UI: 859-3220) QALYs gained and save $14.6 million (95% UI: $5.6-$23.5 million) in health care costs over 10 years, yielding a net cost of $278,000 (95% CI: $177,000-$679,000) per QALY gained. We project greater reductions in obesity prevalence among Hispanic/Latino and Black versus White populations. CONCLUSIONS: The HWC is relatively low-cost per child and projected to reduce obesity disparities if implemented nationally in FQHCs.

Cost of overweight, obesity, and related complications in Switzerland 2021.

Background: The prevalence of obesity has increased significantly in recent decades. Today, it is estimated that more than one-third of the world's population has overweight or obesity, rendering it one of the most significant global health concerns. This article provides a current estimate of the direct costs associated with managing overweight and obesity, including treatment of related complications, among adolescents (≥15 years) and adults in Switzerland. Methods: Prevalence of overweight and obesity based on the BMI reported in the 2017 Swiss Health Survey was extrapolated to 2021. Systematic literature searches were performed to identify treatment costs and epidemiological data of obesity-related complications and costs were extrapolated to 2021. Costing methodology was based on available source data for individual related complications. Treatment costs for complications attributable to overweight and obesity were estimated by applying their population attributable fraction (PAF). Results: More than 3.1 million inhabitants of Switzerland aged ≥15 years met the criteria for overweight or obesity in 2021. The prevalence of overweight increase over the past decades from 30.4% in 1992 to 41.9% in 2017 while prevalence of obesity doubled from 5.4 to 11.3%. Overall, the total attributable costs of overweight and obesity caused by seven assessed obesity-related complications (asthma, coronary heart disease, depression, diabetes mellitus, hypertension, osteoarthritis, and stroke) are estimated at CHF 3657-5208 million with most of the costs (97-98%) caused by the assessed obesity-related complications. Only 2-3% of the total costs were attributable to the combined direct management of overweight and obesity by bariatric surgery (CHF 83 million), pharmacological therapy (CHF 26 million) and dietary counseling (CHF 18 million). Conclusion: Overweight and obesity impose a significant cost impact on the Swiss healthcare system, accounting for 4.2-6.1% of total healthcare expenditures in 2021. Notably, direct treatment of overweight and obesity accounts for only 0.08-0.18% of the total healthcare expenditures. The analysis also revealed a significant lack of available health economic evidence, necessitating the use of assumptions and approximations in this estimation. This is noteworthy, as respective data would be available in healthcare systems but are either unpublished or inaccessible.

Cross-sectional and longitudinal associations among healthcare costs and deficit accumulation.

BACKGROUND: Type 2 diabetes mellitus and overweight/obesity increase healthcare costs. Both are also associated with accelerated aging. However, the contributions of this accelerated aging to increased healthcare costs are unknown. METHODS: We use data from a 8-year longitudinal cohort followed at 16 U.S. clinical research sites. Participants were adults aged 45-76 years with established type 2 diabetes and overweight or obesity who had enrolled in the Action for Health in Diabetes clinical trial. They were randomly (1:1) assigned to either an intensive lifestyle intervention focused on weight loss versus a comparator of diabetes support and education. A validated deficit accumulation frailty index (FI) was used to characterize biological aging. Discounted annual healthcare costs were estimated using national databases in 2012 dollars. Descriptive characteristics were collected by trained and certified staff. RESULTS: Compared with participants in the lowest tertile (least frail) of baseline FI, those in the highest tertile (most frail) at Year 1 averaged $714 (42%) higher medication costs, $244 (22%) higher outpatient costs, and $800 (134%) higher hospitalization costs (p < 0.001). At Years 4 and 8, relatively greater increases in FI (third vs. first tertile) were associated with an approximate doubling of total healthcare costs (p < 0.001). Mean (95% confidence interval) relative annual savings in healthcare costs associated with randomization to the intensive lifestyle intervention were $437 ($195, $579) per year during Years 1-4 and $461 ($232, $690) per year during Years 1-8. These were attenuated and the 95% confidence interval no longer excluded $0 after adjustment for the annual FI differences from baseline. CONCLUSIONS: Deficit accumulation frailty tracks well with healthcare costs among adults with type 2 diabetes and overweight or obesity. It may serve as a useful marker to project healthcare needs and as an intermediate outcome in clinical trials.

"We're one small piece of the puzzle": evaluating the impact of short-term funding for tier two weight management services.

Introduction: Overweight and obesity are a global health epidemic and many attempts have been made to address the rising prevalence. In March 2021 the UK government announced £100 million of additional funding for weight management provisions. Of this, £30.5 million was split across local authorities in England to support the expansion of tier two behavioural weight management services for adults. The present work aimed to explore how this funding was used within the Yorkshire and Humber region to consolidate learning, collate best practice, and provide recommendations for future funding use. Method: One-hour semi-structured interviews were conducted with 11 weight management service commissioners representing 9 of the 15 local authorities in the region. Interviews were recorded, transcribed and analysed using an established health inequality framework. From this, recommendations were co-developed with the commissioner group to establish best practice for future funding use. Results: Commissioners recognised that targeted weight management services were only one small piece of the puzzle for effectively managing obesity. Therefore, recommendations include targeting underserved communities, focussing on early prevention, addressing weight management in a whole systems context, and embracing innovative and holistic approaches to weight management. Discussion: Current short-term funding and restrictive commissioning processes of tier two services prevents sustainable and innovative weight management practice which is detrimental to patients, falls short of addressing health inequalities and negatively impacts staff health and wellbeing.

Cost-effectiveness analysis of once-weekly semaglutide vs. once-daily liraglutide administered subcutaneously in patients with overweight and obesity: a decision analysis.

OBJECTIVE: Obesity presents an enduring and multifaceted dilemma that impacts individuals, society, economies, and healthcare systems alike. Glucagon-like peptide-1 (GLP-1) receptor agonists, including liraglutide and semaglutide, have received FDA approval for obesity treatment. This study aims to present a cost-effectiveness analysis to compare the cost and clinical outcomes of semaglutide vs. liraglutide on weight loss in people with overweight and obesity. MATERIALS AND METHODS: A cost-effectiveness analysis was conducted to compare the cost and the clinical outcomes of adding weekly 2.4 mg SC semaglutide vs. daily 3.0 mg SC liraglutide or placebo to physical activity and diet control in overweight and obese patients. A clinical outcome of achieving ≥15% weight loss was chosen. A simple decision analysis model from a third-payer perspective was applied. Drug costs were based on the retail price of the USA market. One-way sensitivity analyses were performed. RESULTS: Results showed that 2.4 mg weekly semaglutide, when added to physical activity and diet control, was the most cost-effective choice in terms of ≥15% weight loss (ICER: $ 7,056/patient/68 weeks). The model was robust against the 50% increase in the unit cost of semaglutide and the 50% decrease in the unit cost of liraglutide, as well as the changes in probabilities by the corresponding 95% confidence intervals across the model. CONCLUSIONS: This cost-effectiveness analysis suggests that employing once-weekly 2.4 mg semaglutide emerges as a remarkably cost-effective option when contrasted with once-daily 3.0 mg liraglutide in patients with overweight and obesity when added to physical activity and diet control.

Differences in healthcare costs over 10 years following discharge from military service by weight trajectory.

The prevalence of overweight and obesity among military personnel has increased substantially in the past two decades. Following military discharge many personnel can receive integrated health care from the Veterans Health Administration. Prior research related to the economic impacts of obesity has not examined health care costs following the transition into civilian life following military discharge. To address this evidence gap, this study sought to compare longitudinal costs over 10 years across weight categories among VA enrollees recently discharged from the military.

Cost-Effectiveness of Community-Based Diet and Exercise for Patients with Knee Osteoarthritis and Obesity or Overweight.

OBJECTIVE: Obesity exacerbates pain and functional limitation in persons with knee osteoarthritis (OA). In the Weight Loss and Exercise for Communities with Arthritis in North Carolina (WE-CAN) study, a community-based diet and exercise (D + E) intervention led to an additional 6 kg weight loss and 20% greater pain relief in persons with knee OA and body mass index (BMI) >27 kg/m2 relative to a group-based health education (HE) intervention. We sought to determine the incremental cost-effectiveness of the usual care (UC), UC + HE, and UC + (D + E) programs, comparing each strategy with the "next-best" strategy ranked by increasing lifetime cost. METHODS: We used the Osteoarthritis Policy Model to project long-term clinical and economic benefits of the WE-CAN interventions. We considered three strategies: UC, UC + HE, and UC + (D + E). We derived cohort characteristics, weight, and pain reduction from the WE-CAN trial. Our outcomes included quality-adjusted life years (QALYs), cost, and incremental cost-effectiveness ratios (ICERs). RESULTS: In a cohort with mean age 65 years, BMI 37 kg/m2, and Western Ontario and McMaster Universities Osteoarthritis Index pain score 38 (scale 0-100, 100 = worst), UC leads to 9.36 QALYs/person, compared with 9.44 QALYs for UC + HE and 9.49 QALYS for UC + (D + E). The corresponding lifetime costs are $147,102, $148,139, and $151,478. From the societal perspective, UC + HE leads to an ICER of $12,700/QALY; adding D + E to UC leads to an ICER of $61,700/QALY. CONCLUSION: The community-based D + E program for persons with knee OA and BMI >27kg/m2 could be cost-effective for willingness-to-pay thresholds greater than $62,000/QALY. These findings suggest that incorporation of community-based D + E programs into OA care may be beneficial for public health.

Lifetime costs of overweight and obesity in Italy.

We use longitudinal electronic clinical data on a large representative sample of the Italian population to estimate the lifetime profile costs of different BMI classes - normal weight, overweight, and obese (I, II, and III) - in a primary care setting. Our research reveals that obese patients generate the highest cost differential throughout their lives compared to normal weight patients. Moreover, we show that overweight individuals spend less than those with normal weight, primarily due to reduced expenditures beginning in early middle age. Our estimates could serve as a vital benchmark for policymakers looking to prioritize public interventions that address the obesity pandemic while considering the increasing obesity rates projected by the OECD until 2030.

Out-of-Pocket Expenses in Households of People Living with Obesity in France.

BACKGROUND/OBJECTIVES: Overweight and obesity result in a substantial economic burden in both low- and high-income countries. Moreover, this burden is often underestimated because it only partially accounts for unreimbursed out-of-pocket expenses (OOPE) related to obesity. The objective of our study was not only to evaluate OOPE incurred by people with obesity in relation to their disease with respect to direct medical expenditures and direct non-medical expenditures but also the proportion of people living with obesity who have forgone obesity-related healthcare due to the costs of such care. METHODS: An observational descriptive survey was conducted among people with class II/III obesity attending six obesity treatment centers in France. Volunteer adult participants completed a written/phone questionnaire on their related expenditures over the last 6 months for current expenditures and over the last 5 years for occasional ones. The costs were expressed in 2022 EUR. RESULTS: 299 people participated (age: 46 years [SD: 13.9], women: 72%, BMI ≥40 kg/m2: 62% and 48% with comorbidities). 65% had a professional activity. 83% declared that they had OOPE related to obesity representing annually EUR 2027/individual on average (5% of the household revenue), including weight loss and nutritional products, vitamins, meal programs, gym memberships, psychologists, but mainly adapted clothing, additional travel costs, and others. 15% of the respondents had to modify their professional activity due to obesity and 15% forwent some medical care in the last 12 months. CONCLUSIONS: OOPE is a significant part of the economic burden of obesity. Despite some limitations due to the specificities of the participants and because some costs may be more related to social activities affected by obesity than to healthcare, it seems important to consider these expenditures in cost estimates for obesity.

Determinantes sociales asociados a la seguridad alimentaria y nutricional en hogares de mujeres con exceso de peso de Girardot, Cundinamarca (Colombia) / Approach from social determinants to food and nutritional security in households of overweight women in Girardot

Fundamentos: los resultados de la Encuesta Nacional de Situación Nutricional (ENSIN) de los últimos 15 años muestran un marcado aumento en el exceso de peso en adultos. En 2015, el 59,6% de las mujeres entre 18 y 64 años presentó exceso de peso.

Effect of Gamification With and Without Financial Incentives to Increase Physical Activity Among Veterans Classified as Having Obesity or Overweight: A Randomized Clinical Trial.

Importance: Gamification is increasingly being used for health promotion but has not been well tested with financial incentives or among veterans. Objective: To test the effectiveness of gamification with social support, with and without a loss-framed financial incentive, to increase physical activity among veterans classified as having overweight and obesity. Design, Setting, and Participants: This 3-group randomized clinical trial had a 12-week intervention period and an 8-week follow-up period. Participants included veterans with a body mass index greater than or equal to 25 who were receiving care from a single site in Philadelphia, Pennsylvania. Participants underwent a remotely monitored intervention from March 19, 2019, to August 9, 2020. Data analyses were conducted between October 1, 2020, and November 14, 2020. Interventions: All participants received a wearable device to track step counts and selected a step goal. The control group received feedback from their devices only. Participants in the 2 gamification groups were entered into a 12-week game with points and levels designed using behavioral economic principles and selected a support partner to receive weekly updates. Participants in the loss-framed financial incentive group had $120 allocated to a virtual account and lost $10 if weekly goals were not achieved. Main Outcomes and Measures: The primary outcome was the change in mean daily steps from baseline during the intervention. Secondary outcomes include proportion of days goals were achieved and changes during follow-up. Results: A total of 180 participants were randomized, 60 to the gamification with social support group, 60 to the gamification with social support and loss-framed financial incentives group, and 60 to the control group. The participants had a mean (SD) age of 56.5 (12.9) years and a mean (SD) body mass index of 33.0 (5.6); 71 participants (39.4%) were women, 90 (50.0%) were White, and 67 (37.2%) were Black. During the intervention period, compared with control group participants, participants in the gamification with financial incentives group had a significant increase in mean daily steps from baseline (adjusted difference, 1224 steps; 95% CI, 451 to 1996 steps; P = .005), but participants in the gamification without financial incentives group did not (adjusted difference, 433 steps; 95% CI, -337 to 1203 steps; P = .81). The increase for the gamification with financial incentives group was not sustained during the follow-up period, and the step count was not significantly different than that of the control group (adjusted difference, 564 steps; 95% CI, -261 to 1389 steps; P = .37). Compared with the control group, participants in the intervention groups had a significantly higher adjusted proportion of days meeting their step goal during the main intervention and follow-up period (gamification with social support group, adjusted difference from control, 0.21 participant-day; 95% CI, 0.18-0.24 participant-day; P < .001; gamification with social support and loss-framed financial incentive group, adjusted difference from control, 0.34 participant-day; 95% CI, 0.31-0.37 participant-day; P < .001). Conclusions and Relevance: Among veterans classified as having overweight and obesity, gamification with social support combined with loss-framed financial incentives was associated with a modest increase in physical activity during the intervention period, but the increase was not sustained during follow-up. Gamification without incentives did not significantly change physical activity. Trial Registration: ClinicalTrials.gov Identifier: NCT03563027.

Financial implications of New York City's weight management initiative.

PURPOSE: To estimate potential annual savings in medical expenditures from a subsidized weight management program from the NYC Government perspective. DESIGN: Longitudinal observational study. SETTING: Employees of New York City (NYC) government and enrolled dependents. SAMPLE: 14,946 participants with overweight and obesity. INTERVENTION: WW (formerly Weight Watchers®) 'Workshop' and 'Digital' programs. MEASURES: Participation rate, enrollment duration, weight change, and predicted gross and net total and per capita medical expenditure savings and return on investment (ROI). ANALYSIS: Participation rate, enrollment duration, weight change, and program costs are based on direct observation. Predicted savings are simulated based on published data relating weight loss to medical expenditure reductions. RESULTS: In total, 47% of participating employees and 50% of participating dependents lost weight during the enrollment period. Mean (median) enrollment duration for employees was 7.1 months (7.0) and for dependents was 6.9 months (6.0). Mean (median) weight losses for the employees in 'Workshops' and 'Digital' was 6.6 lbs (2.80) and 6.3 lbs (0.0). For dependents, weight losses were 7.4 lbs (3.59) and 11.6 lbs (2.0). Per capita and total predicted net savings to NYC Government from employees was estimated to be $120 and $1,486,102 for an ROI of 143%. Including dependents, predicted net savings increases to $1,963,431 for an ROI of 189%. Over 80% of savings came from participants in the Obese III category. CONCLUSION: An evidence-based weight management program has the potential to generate a positive ROI for employers. Future studies should validate these estimates using actual data and more rigorous designs.

Comparative Costs of a Parent-Only and Parent and Child Treatment for Children with Overweight or Obesity.

OBJECTIVE: Models such as family-based treatment (FBT), delivered to both the parent and child, are considered the most efficacious intervention for children with obesity. However, recent research suggests that parent-based treatment (PBT; or parent-only treatment) is noninferior to FBT. The aim of this study was to evaluate the comparative costs of the FBT and PBT models. METHODS: A total of 150 children with overweight and obesity and their parents were randomized to one of two 6-month treatment programs (FBT or PBT). Data was collected at baseline, during treatment, and following treatment, and and trial-based analyses of the costs were conducted from a health care sector perspective and a limited societal perspective. RESULTS: Results suggest that PBT, compared with FBT, had lower costs per parent-child dyad from the health care sector perspective (PBT = $2,886; FBT = $3,899) and from a limited societal perspective (PBT = $3,231; FBT = $4,279). CONCLUSIONS: These findings suggest that a PBT intervention has lower costs and is noninferior to an FBT intervention for both child and parent weight loss.

Diverticular Disease Epidemiology: Rising Rates of Diverticular Disease Mortality Across Developing Nations.

BACKGROUND: The incidence of diverticular disease is growing in the Western world. However, the global burden of disease is unknown in the developing world. OBJECTIVE: This study aimed to determine the global burden of diverticular disease as measured by disease-specific mortality while identifying indicators of rising disease rates. DESIGN: We undertook an ecological analysis based on data from the World Health Organization Mortality Database. Then, we analyzed global age-adjusted mortality rates from diverticular disease and compared them to national rates of overweight adults, health expenditures, and dietary composition. SETTINGS: National vital statistics data were collected. PATIENTS: Diverticular disease deaths from January 1, 1994 through December 31, 2016 were evaluated. MAIN OUTCOME MEASURES: The primary outcome measured was the national age-adjusted mortality rate. RESULTS: The average age-adjusted mortality rate for diverticular disease was 0.51 ± 0.31/100,000 with a range of 0.11 to 1.75/100,000. During the study period, we noted that 57% of nations had increasing diverticular disease mortality rates, whereas only 7% had decreasing rates. More developed nations (40%) than developing nations (24%) were categorized as having high diverticular disease mortality burden over the time period of the study, and developed nations had higher percentages of overweight adults (58.9 ± 3.1%) than developing nations (50.6 ± 6.7%; p < 0.0001). However, developing nations revealed more rapid increases in diverticular disease mortality (0.027 ± 0.024/100,000 per year) than developed nations (0.005 ± 0.025/100,000 per year; p = 0.001), as well as faster expanding proportions of overweight adults (0.76 ± 0.12% per year) than in already developed nations (0.53 ± 0.10% per year; p<0.0001). LIMITATIONS: Ecological studies cannot define cause and effect. CONCLUSIONS: There is considerable variability in diverticular disease mortality across the globe. Developing nations were characterized by rapid increases in diverticular disease mortality and expanding percentages of overweight adults. Public health interventions in developing nations are needed to alter mortality rates from diverticular disease. See Video Abstract at http://links.lww.com/DCR/B397. EPIDEMIOLOGÍA DE LA ENFERMEDAD DIVERTICULAR: TASAS CRECIENTES DE MORTALIDAD POR ENFERMEDAD DIVERTICULAR EN LOS PAÍSES EN DESARROLLO: La incidencia de la enfermedad diverticular está creciendo en el mundo occidental. Sin embargo, la carga mundial de la enfermedad es desconocida en el mundo en desarrollo.Determinar la carga global de la enfermedad diverticular medida por la mortalidad específica de la enfermedad mientras se identifican los indicadores de aumento de las tasas de enfermedad.Realizamos un análisis ecológico basado en datos de la Base de datos de mortalidad de la Organización Mundial de la Salud. Luego, analizamos las tasas globales de mortalidad ajustadas por edad por enfermedad diverticular y las comparamos con las tasas nacionales de adultos con sobrepeso, gastos de salud y composición dietética.Datos nacionales de estadísticas vitales.Muertes por enfermedades diverticulares desde el 1 de enero de 1994 hasta el 31 de diciembre de 2016.Tasa nacional de mortalidad ajustada por edad.La tasa promedio de mortalidad ajustada por edad para la enfermedad diverticular fue de 0,51 ± 0,31 / 100,000 con un rango de 0,11 a 1,75 / 100,000. Durante el período de estudio, notamos que el 57% de las naciones tenían tasas crecientes de mortalidad por enfermedades diverticulares, mientras que solo el 7% tenían tasas decrecientes. Las naciones más desarrolladas (40%) que las naciones en desarrollo (24%) se clasificaron como que tienen una alta carga de mortalidad por enfermedad diverticular durante el período de tiempo del estudio, y las naciones desarrolladas tuvieron porcentajes más altos de adultos con sobrepeso (58.9 ± 3.1%) que las naciones en desarrollo (50,6 ± 6,7%) (p <0,0001). Sin embargo, las naciones en desarrollo revelaron aumentos más rápidos en la mortalidad por enfermedades diverticulares (0.027 ± 0.024 / 100,000 por año) que las naciones desarrolladas (0.005 ± 0.025 / 100,000 por año) (p = 0.001), así como proporciones de adultos con sobrepeso en expansión más rápida (0.76 ± 0.12% por año) que en las naciones ya desarrolladas (0.53 ± 0.10% por año) (p <0.0001).Los estudios ecológicos no pueden definir causa y efecto.Existe una considerable variabilidad en la mortalidad por enfermedad diverticular en todo el mundo. Los países en desarrollo se caracterizaron por un rápido aumento en la mortalidad por enfermedades diverticulares y porcentajes crecientes de adultos con sobrepeso. Se necesitan intervenciones de salud pública en los países en desarrollo para alterar las tasas de mortalidad por enfermedad diverticular. Consulte Video Resumen en http://links.lww.com/DCR/B397.

Is Japan's child allowance effective for the well-being of children? A statistical evaluation using data from K-CHILD study.

BACKGROUND: Child allowance payment is one form of social security policy that aims to mitigate the child poverty gap by providing financial support to families. This study aimed to explore the impact of the child allowance on children's physical and mental health (BMI, problem behavior, depression, and self-rated health), and parental investment in child health (children's material goods, family events, extracurricular activities, interaction with children, and involvement in child maltreatment). METHODS: We used cross-sectional data from the 2016 Kochi Child Health Impact of Living Difficulty (K-CHILD) study. Participants were 1st, 5th and 8th grade children living in Kochi prefecture in Japan (N = 8207). Caregivers reported children's child allowance status, BMI and behavior problems, while children filled out a self-assessment on depression and health condition. Propensity score matching analysis regarding potential confounders was used. RESULTS: We found that children in families that received child allowance showed a smaller total difficulties score by 1.29 points (95% CI: - 2.32 to - 0.25) and a lower risk of overweight (OR: 0.51, 95% CI: 0.29 to 0.91) although there is no association with underweight, prosocial behavior, depressive symptoms and self-rated health. Parental investment did not differ by child allowance status (p > 0.05). CONCLUSIONS: Child allowance was found to be potentially beneficial in decreasing behavior problems and reducing child overweight. Further longitudinal studies are needed to elucidate how child allowance is used by family members and associated with children's well-being. (230/350 words).

Health care cost of overweight-related diseases in Bangladesh.

OBJECTIVE: To estimate the economic burden of overweight in Bangladesh. DESIGN: We used data from Household Income and Expenditure Survey, 2010. A prevalence-based approach was used to calculate the population attributable fraction (PAF) for diseases attributable to overweight. Cost of illness methodology was used to calculate annual out of pocket (OOP) expenditure for each disease using nationally representative survey data. The cost attributable to overweight for each disease was estimated by multiplying the PAF by annual OOP expenditure. The total cost of overweight was estimated by adding PAF-weighted costs of treating the diseases. SETTING: Nationwide, covering the whole of Bangladesh. PARTICIPANTS: Individuals whose BMI ≥ 25 kg/m2. RESULTS: The total cost attributable to overweight in Bangladesh in 2010 was estimated at US$147·38 million. This represented about 0·13 % of Bangladesh's Gross Domestic Product and 3·69 % of total health care expenditure in 2010. The sensitivity analysis revealed that the total cost could be as high as US$334 million or as low as US$71 million. CONCLUSIONS: A substantial amount of health care resource is devoted to the treatment of overweight-related diseases in Bangladesh. Effective national strategies for overweight prevention programme should be established and implemented.

The influence of socioeconomic status and age on the prevalence of overweight and obesity among 5 to 10-year-old children in Curitiba, Brazil.

OBJECTIVE: The aim of this study was to examine the influence of the socioeconomic status (SES) and age on the prevalence of overweight and obesity among 5 to 10-year-old children from Brazil. METHODS: The sample consisted of 80 782 (41 063 boys) students aged 5 to 10-year-old. Height and weight were measured and body mass index (BMI) was calculated. SES was self-reported by parents when registering for school in the same year as the assessment. RESULTS: An increasing trend in the prevalence of obesity, for boys and girls, and overweight, for girls, as they got older was observed. The prevalence of obesity was greater among medium SES boys, 18.1% (95% CI: 17.7, 18.6), and girls, 18.1% (95% CI: 17.7, 18.6), compared with low SES. For each year boys and girls get older their odds of being underweight, overweight and obese increase. Medium and high SES boys were 23% (95% CI: 1.14, 1.32) and 25% (95%CI: 1.03, 1.52) more likely to be obese than low SES boys. Girls with high SES were 20% (OR = 1.20; 95% CI: 1.10, 1.31) more likely of being obese than girls with low SES. Furthermore, age and being in the medium SES for both sexes and in the high SES for boys was positively related to the BMI z-score. CONCLUSION: Both age and SES were factors associated with obesity among Brazilian children. For public health policies to be effective, it is necessary to understand why higher SES children and older children have higher risk and prevalence of obesity and overweight.
