This review aims to identify the associated attributes of willingness to pay (WTP) for overweight and obesity interventions. A narrative review was conducted by partially adopting the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. A non-exhaustive search using a pre-defined strategy and keywords was done on three selected literature databases: Pubmed, Scopus, and Web of Science. The inclusion criteria for the review were original studies written in English, published between 2000 and 2022, and focused on WTP for overweight and obesity interventions in adults. The extracted studies were manually screened for their eligibility through three cascading tiers: the title, the abstract, and the full article. Only nine original studies were eligible for review based on the screening procedure of 40 screened articles. There was heterogeneity in the study designs, methods, target populations, study duration, and perspectives across the studies. The majority of the studies showed that higher WTP was associated with younger age, having higher income, being female, having higher body mass index (BMI), having the perception of being overweight, habits, and attitudes. WTP is also attributed to the associated percentage of weight loss, long-term health risk reduction, time to noticeable weight loss, delivery mode, side effects, lifestyle modification, and costs of interventions. The identification of common attributes of the WTP for overweight and obesity intervention can assist in the formulation and implementation of effective evidence-based policies. Specific sub-groups with low WTP could be targeted via unique initiatives to improve their participation in weight-loss interventions.

Effect of Vitamin D Supplementation on Lipid Profile in Overweight or Obese Women: A Meta-analysis and Systematic Review of Randomized Controlled Trials.
Nutr Rev
January 2025
Department of Emergency Medicine, The Affiliated Hospital, Southwest Medical University, Luzhou, Sichuan 64600, China.
Context: Previous studies have explored the relationship between vitamin D and lipid profile in individuals with obesity or overweight women, but the results have been inconsistent.
Objective: This meta-analysis and systematic review of randomized controlled trials (RCTs) was conducted to assess the effect of vitamin D on lipid profile in women who are overweight or obese.
Data Sources: A meticulous search strategy was used across the Scopus, PubMed/Medline, Web of Science, and Embase databases up to June 2024.

Background A comprehensive assessment of skeletal muscle health is crucial to understanding the association between improved clinical outcomes and obesity as defined by body mass index (BMI; calculated as weight in kilograms divided by height in meters squared) in lung cancer, but limited studies have been conducted on this topic. Purpose To investigate the association between BMI-defined obesity and survival in patients with non-small cell lung cancer who underwent curative resection, with a specific focus on the status of skeletal muscle assessed at CT. Materials and Methods This retrospective study investigated Korean patients with non-small cell lung cancer who underwent curative resection between January 2008 and December 2019.

Obesity (Silver Spring)
February 2025
Department of Radiology, Nanjing Drum Tower Hospital, Affiliated Hospital of Medical School, Nanjing University, Nanjing, China.
Objective: The objective of this study was to investigate underlying mechanisms of long-term effective weight loss after laparoscopic sleeve gastrectomy (LSG) and effects on the medial orbitofrontal cortex (mOFC) and cognition.
Methods: A total of 18 individuals with obesity (BMI ≥ 30 kg/m) underwent LSG. Clinical data, cognitive scores, and brain magnetic resonance imaging scans were evaluated before LSG and 12 months after LSG.
Trajectories of general and central obesity beyond middle age in relation to late-life cognitive decline and dementia.
Obesity (Silver Spring)
February 2025
Nuffield Department of Population Health, University of Oxford, Oxford, UK.
Objective: The objective was to evaluate the longitudinal patterns of central and general obesity, identify their genetic and behavioral risk determinants, and investigate the association of distinct obesity trajectories beyond middle age with subsequent cognitive decline and the risk of developing dementia in late life.
Methods: Using a nationally representative, longitudinal, community-based cohort, we examined trajectory patterns of obesity over a 14-year span beyond middle age employing latent mixture modeling. We then evaluated their relationship with subsequent cognitive decline through linear mixed models and with the risk of developing dementia using Cox models, adjusting for confounding variables.
Trends and Factors Associated With Central Obesity in Schoolchildren in Florianópolis, Santa Catarina, Brazil: Cross Sectional Panel Study From 2002 to 2019.
Am J Hum Biol
January 2025
Federal University of Santa Catarina, Posgraduate Program in Nutrition, Federal University of Santa Catarina, Florianópolis, SC, Brazil.
Objective: This study aimed to assess the trend and factors associated with central obesity in four cross-sectional panels in schoolchildren aged 7-14 years between 2002 and 2019.
Methods: Waist circumference data were used to assess central obesity, and independent variables were gender, age, school shift (morning and afternoon), commuting to school method, mother's schooling, and family income. The chi-square test was used to assess the association between outcome and independent variables, and binary logistic regression was used to assess the predictors of central obesity and the effect size by odds ratio.
