乳腺癌患者体力活动随机对照试验 (RCT) 的代表性对于考虑特权社会群体的可行性和有效性分析至关重要。通过试验过程逐步排除弱势群体可能会加剧健康不平等。本研究旨在检验乳腺癌（BC）体力活动试验的代表性，调查社会经济地位（SES）与干预依从性之间的关联，并探讨代表性与SES与干预依从性之间的关系之间的关联。进行了系统的计算机化搜索在 PubMed、CINAHL、AMED、EMBASE 和 PsycINFO 中。其他基于引文的搜索检索到 37 篇文章。将研究样本中教育水平、种族和婚姻状况的分布与全国人口数据进行比较，以估计弱势群体的代表性。大部分研究偏向于受过教育、已婚和白人患者。只有六项研究报告了 SES 依从关系，这妨碍了对这种关系以及代表性和 SES 依从关系之间可能存在的关联的结论。 受教育程度较低、未婚和非白人个体在 BC 省体力活动随机对照试验中可能代表性不足，而 SES 依从关系在此类试验尚无定论。无意识的社会歪曲可能表明，伪装的不平等值得重新关注。版权所有 © 2024 Stalsberg 和 Darvik。

Representativeness in physical activity randomised controlled trials (RCT) in breast cancer patients is essential to analyses of feasibility and validity considering privileged- social groups. A step-by-step exclusion of less privileged groups through the trial process could reinforce health inequality. This study aimed at examining representativeness in breast cancer (BC) physical activity trials, investigate associations between socio-economic status (SES) and intervention adherence, and explore associations between representativeness and the relationship between SES and intervention adherence.Systematic, computerised searches were performed in PubMed, CINAHL, AMED, EMBASE and PsycINFO. Additional citation-based searches retrieved 37 articles. Distributions of education level, ethnicity, and marital status in study samples were compared to national populations data to estimate representativeness in less privileged groups.A preponderance of studies favoured educated, married and white patients. Only six studies reported SES-adherence associations, hampering conclusions on this relationship and possible associations between representativeness and an SES-adherence relationship.Less educated, unmarried and non-white individuals may be underrepresented in BC physical activity RCTs, while SES-adherence associations in such trials are inconclusive. Unintentional social misrepresentations may indicate that disguised inequity warrants revived attention.Copyright © 2024 Stalsberg and Darvik.
