There is a lack of research on individual perceptions of social experiences and social relationships among very preterm (VP) adults compared with term-born peers.

To investigate self-perceived social functioning in adults born VP (<32 weeks’ gestation) and/or with very low birth weight (VLBW) (<1500g) compared with term-born adults (≥37 weeks’ gestation) using an individual participant data (IPD) meta-analysis.

Two international consortia: Research on European Children and Adults born Preterm and Adults Born Preterm International Collaboration.

Cohorts with outcomes assessed by using the Adult Self-Report Adaptive Functioning scales (friends, spouse/partner, family, job, and education) in both groups.

IPD from 5 eligible cohorts were collected. Raw-sum scores for each scale were standardized as z scores by using mean and SD of controls for each cohort. Pooled effect size was measured by difference () in means between groups.

One-stage analyses (1285 participants) revealed significantly lower scores for relationships with friends in VP/VLBW adults compared with controls ( –0.37, 95% confidence interval [CI]: –0.61 to –0.13). Differences were similar after adjusting for sex, age, and socioeconomic status ( –0.39, 95% CI: –0.63 to –0.15) and after excluding participants with neurosensory impairment ( –0.34, 95% CI: –0.61 to –0.07). No significant differences were found in other domains.

Generalizability of research findings to VP survivors born in recent decades.

VP/VLBW adults scored their relationship with friends lower but perceived their family and partner relationships, as well as work and educational experiences, as comparable to those of controls.

与足月出生的同龄人相比，缺乏对极早产 (VP) 成年人的社会经历和社会关系的个人看法的研究。

使用个体参与者调查出生 VP（<32 孕周）和/或极低出生体重（VLBW）（<1500g）的成人与足月出生的成人（≥37 孕周）相比的自我感知社会功能数据（IPD）荟萃分析。

两个国际联盟：研究欧洲早产儿和成人早产儿和成人早产儿国际合作。

在两组中使用成人自我报告自适应功能量表（朋友、配偶/伴侣、家庭、工作和教育）评估结果的队列。

收集了来自 5 个符合条件的队列的 IPD。通过使用每个队列的对照组的平均值和 SD，将每个量表的原始总和分数标准化为z分数。通过组间平均值的差异 () 来衡量合并效应大小。

一阶段分析（1285 名参与者）显示，与对照组相比，VP/VLBW 成年人与朋友的关系得分显着低于对照组（–0.37，95% 置信区间 [CI]：–0.61 至 –0.13）。在调整性别、年龄和社会经济地位（–0.39，95% CI：–0.63 至 –0.15）和排除神经感觉障碍的参与者（–0.34，95% CI：–0.61 至 –0.07）后，差异相似。在其他领域没有发现显着差异。

研究结果对近几十年出生的副总裁幸存者的普遍性。

VP/VLBW 成年人对他们与朋友的关系评分较低，但认为他们的家庭和伴侣关系以及工作和教育经历与对照组相当。
