Individuals who grow up in low-socioeconomic status (SES) families are at an increased risk of health problems across the lifespan. Although supportive social relationships are postulated to be a protective factor for the health of these individuals, the role of friend support in adolescence is not well understood. Given that low-grade inflammation is one key biological mechanism proposed to explain links between family SES and health outcomes, we examined whether adolescents' friend support buffers the association between family SES and low-grade inflammation among adolescents.
277 dyads of adolescents (63.5% female; 39.4% White, 38.3% Black, and 32.1% Hispanic; = 13.92 years) and one of their parents participated in this longitudinal study (two waves approximately 2 years apart). Parents reported family objective SES (i.e., income, savings, and education) and family subjective SES (i.e., subjective social status). Adolescents reported perceived friend support. Fasting antecubital blood was drawn from adolescents at both visits. Low-grade inflammatory activity was represented by a composite of inflammatory biomarkers and numbers of classical monocytes.
Adolescents' friend support moderated the associations of family subjective SES with both the inflammation composite and classical monocyte counts across cross-sectional, longitudinal, and prospective change (only significant for the inflammation composite) analyses. Specifically, lower family subjective SES was associated with higher levels of low-grade inflammation only among adolescents lower, but not higher, in friend support. No moderation was observed for objective SES.

在整个生命周期中，成长于低社会经济地位（SES）家庭的个体患健康问题的风险增加。尽管支持性的社会关系被认为是保护这些个体健康的一个因素，但朋友支持在青少年时期的作用还不太清楚。由于低度炎症是解释家庭 SES 与健康结果之间联系的一个关键生物学机制，我们研究了青少年的朋友支持是否缓冲了家庭 SES 与青少年低度炎症之间的关联。
277 对青少年（63.5%女性；39.4%白人，38.3%黑人，32.1%西班牙裔；平均年龄= 13.92 岁）及其父母中的一人参加了这项纵向研究（两次访问大约相隔 2 年）。父母报告了家庭客观 SES（即收入、储蓄和教育）和家庭主观 SES（即主观社会地位）。青少年报告了感知到的朋友支持。在两次访问时都从青少年抽取空腹肘前血样。低度炎症活性由炎症生物标志物和经典单核细胞数量的综合指标表示。
青少年的朋友支持调节了家庭主观 SES 与炎症综合指标和经典单核细胞计数之间的关联，无论是在横断面、纵向还是前瞻性变化（仅在炎症综合指标上显著）分析中。具体来说，只有在朋友支持较低的青少年中，较低的家庭主观 SES 与较高水平的低度炎症相关，而在朋友支持较高的青少年中则没有这种关联。客观 SES 没有观察到调节作用。
