对肥胖者的负面成见、偏见和歧视的证据已被广泛记录在案。然而，体型较大对社交网络关系或友谊形成的影响还不太清楚。在这篇文章中，我们探讨了较高的体重在多大程度上导致青少年的社会边缘化。使用来自全国具有代表性的青少年样本的数据，我们估计了内生性校正模型，包括解释双向的学校水平固定效应和未观察到的混杂因素，以确定体重对社交网络关系的影响。我们发现，与非肥胖青少年相比，肥胖青少年的朋友更少，社交融合度也更低。我们还发现，在友谊网络中，这样的惩罚存在于白人中，而不是非裔美国人或拉美裔美国人，在白人女性中影响最大。这些结果对学校层面的常见环境影响，以及对偏好、风险态度、低自尊和外表吸引力的客观衡量的控制都是稳健的。爱思唯尔出版公司(Elsevier B.V.)
Evidence of negative stereotypes, prejudice and discrimination towards obese individuals has been widely documented. However, the effect of a larger body size on social network ties or friendship formations is less well understood. In this paper, we explore the extent to which higher body weight results in social marginalization of adolescents. Using data from a nationally representative sample of adolescents, we estimate endogeneity-corrected models including school-level fixed effects that account for bi-directionality and unobserved confounders to ascertain the effect of body weight on social network ties. We find that obese adolescents have fewer friends and are less socially integrated than their non-obese counterparts. We also find that such penalties in friendship networks are present among whites but not African-Americans or Hispanics, with the largest effect among white females. These results are robust to common environmental influences at the school-level and to controls for preferences, risk attitudes, low self-esteem and objective measures of physical attractiveness.
