OBJECTIVE
To examine the relationship between the body size norms of Black and Hispanic adults and the body sizes of their social network members.
METHODS
Egocentric network data were examined for 245 adults recruited from 2012-2013 in New York City. A multivariable regression model was used to examine the relationship between participants' perception of normal body size and the body sizes of their network members adjusted for participant age, education, race/ethnicity and network size. Participants' body size norms were also examined stratified by the following characteristics of obese network members: frequency of contact, living proximity, relationship, and importance of relationship.
RESULTS
Index participants were 89% female with mean body mass index 33.5 kg/m. There were 2,571 network members identified (31% overweight, 10% obese). In the fully adjusted multivariable model, perception of normal body size increased as the number of network members with obesity increased (p<0.01). Larger body size norms were associated with increased frequency of contact with obese network members (p=0.04), and obese members living in the home (p=0.049).
CONCLUSIONS
These findings support a relationship between the body size norms of Black and Hispanic adults and their social network body size.
目的
研究黑人和西班牙裔成年人的身体尺寸规范与其社交网络成员身体尺寸之间的关系。
方法
对2012年至2013年在纽约市招募的245名成年人的自我中心网络数据进行了研究。使用多变量回归模型来研究参与者对正常身体尺寸的认知与经参与者年龄、教育程度、种族/民族和网络规模调整后的网络成员身体尺寸之间的关系。还根据肥胖网络成员的以下特征对参与者的身体尺寸规范进行了分层研究：接触频率、居住距离、关系以及关系的重要性。
结果
指标参与者中89%为女性，平均体重指数为33.5kg/m。共识别出2571名网络成员（31%超重，10%肥胖）。在完全调整的多变量模型中，随着肥胖网络成员数量的增加，对正常身体尺寸的认知也增加（p<0.01）。更大的身体尺寸规范与与肥胖网络成员的接触频率增加（p=0.04）以及居住在家中的肥胖成员（p=0.049）有关。
结论
这些发现支持了黑人和西班牙裔成年人的身体尺寸规范与其社交网络身体尺寸之间的关系。
