“…Several studies examined the effectiveness of using network‐based strategies to target individuals for obesity interventions and found various results. Zhang et al (introduced above), Trogdon and Allaire, and El Sayed et al simulated obesity interventions that targeted highly connected individuals in models focused on US children, US adult women, and English adults, respectively; only one study found an effect compared with other strategies, specifically that targeting most popular individuals in the network resulted in greater weight loss than random targeting of individuals with obesity. In a model focused on US youth, Beheshti, Jalalpour, and Glass compared random targeting to two network‐based targeting strategies, targeting based on high risk (ie, high BMI), and targeting of youth in obesogenic environments, and found that the network‐based strategies outperformed the other targeting strategies in terms of nutrition or physical activity intervention effectiveness.…”

A systematic review of system dynamics and agent‐based obesity models: Evaluating obesity as part of the global syndemic

Summary The problem of obesity has recently been reframed as part of the global syndemic—the co‐occurring, interacting pandemics of obesity, undernutrition, and climate change that are driven by common underlying societal drivers. System science modeling approaches may help clarify how these shared drivers operate and the best ways to address them. The objective of this paper was to determine to what extent existing agent‐based and system dynamics computational models of obesity provide insights into the shared drivers of the global syndemic. Peer‐reviewed studies published until July 2018 were identified from Scopus, Web of Science, and PubMed databases. Thirty‐eight studies representing 30 computational models were included. They show a growing use of system dynamics and agent‐based modeling in the past decade. They most often examined mechanisms and interventions in the areas of social network‐based influences on obesity, physiology and disease state mechanics, and the role of food and physical activity environments. Usefulness for identifying common drivers of the global syndemic was mixed; most models represented Western settings and focused on obesity determinants close to the person (eg, social circles, school settings, and neighborhood environments), with a relative paucity in models at mesolevel and macrolevel and in developing country contexts.

This study analyzes peer effects on childhood obesity using data from the first two waves of the IDEFICS study, which applies several anthropometric and other measures of fatness to approximately 14,000 children aged two to nine participating in both waves in 16 regions of eight European countries. Peers are defined as same-sex children in the same school and age group. The results show that peer effects do exist in this European sample but that they differ among both regions and different fatness measures. Peer effects are larger in Spain, Italy, and Cyprus -the more collectivist regions in our sample -while waist circumference generally gives rise to larger peer effects than BMI. We also provide evidence that parental misperceptions of their own children's weight goes hand in hand with fatter peer groups, supporting the notion that in making such assessments, parents compare their children's weight with that of friends and schoolmates.JEL Classification: I12, J13, J22
