To examine the association between social network body size and body size norms in South Asian adults.
Participants (n = 766) from the Mediators of Atherosclerosis in South Asians Living in America (MASALA) study (2014-2018) provided detailed information about their five closest network members. Participants' perceptions of their network members' body sizes, their own body size (self-body size), and a healthy body size for men and women (body size norms) were assessed using the Stunkard 9-figure scale. Adjusted hierarchical linear regression models were used to examine associations between the average body size of network members and perceived body size norms.
Participants' average age was 59.1 years (SD = 9.2) and 44.1% were women. Participants reported an average network body size of 4.0 (SD = 1.1). The average body size norm for male and female Stunkard images was 3.6 (SD = 1.0) and 3.4 (SD = 0.8), respectively. Social network body size was positively associated with increasing body size norms (β-coefficient = 0.31, 95% CI: 0.26, 0.36), independent of self-body size.
Social networks may influence body size norms in South Asian adults. Long-term follow up of the MASALA cohort will determine if social network body size and body size norms are associated with weight- control behaviors and weight change.
研究南亚成年人社交网络体型与体型规范之间的关联。
来自“生活在美国的南亚人动脉粥样硬化的中介因素”（MASALA）研究（2014 - 2018年）的参与者（n = 766）提供了关于其五个最亲密网络成员的详细信息。使用斯坦卡德9分制量表评估参与者对其网络成员体型、自身体型（自我体型）以及男性和女性健康体型（体型规范）的认知。采用调整后的分层线性回归模型来研究网络成员的平均体型与感知体型规范之间的关联。
参与者的平均年龄为59.1岁（标准差 = 9.2），44.1%为女性。参与者报告的社交网络平均体型为4.0（标准差 = 1.1）。男性和女性斯坦卡德图像的平均体型规范分别为3.6（标准差 = 1.0）和3.4（标准差 = 0.8）。社交网络体型与体型规范的增加呈正相关（β系数 = 0.31，95%置信区间：0.26，0.36），与自我体型无关。
社交网络可能会影响南亚成年人的体型规范。对MASALA队列的长期随访将确定社交网络体型和体型规范是否与体重控制行为及体重变化相关。
