Abstract:	Background: Weight-related stigma may exert adverse effects on psychosocial health of children and adolescents, yet possible underlying mechanisms have been less delineated. The present study aims to examine the extent to which overweight status was associated with peer relations and network positions among preadolescent children. Methods: Data were obtained from a 2017 cross-sectional survey conducted in Taiwan's Keelung City, with the study population comprising the fourth graders (9-11 years old) in 42 public schools (n= 2,333, response rate= 97.3%). Body mass index (BMI) was ascertained by self-reported weight and height. Children's school-wide social networks and status (i.e., marginalization and isolation) were assessed by child's peer nomination (maximal five). Linear and generalized mixed-effect models were applied to examine the risk of having few nominations and being isolated by weight status. Results: Overweight children were found to have fewer indegree nominations (4.07 ± 2.83 vs. 3.00 ± 2.42, p<0.0001) and reciprocal ties (1.93 ± 1.45 vs. 1.43 ± 1.31, p<0.0001) as compared with their non-overweight peers. After adjustment for socioeconomic characteristics, participation in school activities, school-level network features (network size, density), and school average BMI, overweight preadolescents received 1.10 fewer nominations (p<0.0001) and were more likely to have 0 indegree nomination (OR: 1.75, 95% confidence intervals [CI]: 1.28-2.39). Overweight may elevate the risk of having a marginal or isolated position in the school-based social network by 71% (95% CI: 1.38-2.12). Gender-stratified analysis indicated that overweight-related increased risk of social isolation was more prominent in girls (OR: 2.63, 95% CI: 1.85-3.74) than in boys (OR: 1.34, 95% CI: 1.01-1.77). Conclusion: Overweight in preadolescence appeared associated with having fewer friends and being marginalized/isolated in school, especially girls. Targeted efforts are needed to ameliorate weight-based social marginalization/isolation and to avoid spiral-down effects throughout adolescence.
