与其他安第斯国家相比，秘鲁的宫颈癌发病率和死亡率较高。因此，政府组织和国际组织之间的伙伴关系以秘鲁农村地区为目标，通过外联活动接受宫颈癌筛查。以前的研究已经发现了一个人的社交网络和癌症筛查行为之间的关系。非营利组织CerviCusco开展的筛查外展活动为社会网络研究创造了机会，以检查2012年和2013年参与这些活动的农村土著社区的宫颈癌筛查历史和社会网络特征。本研究的目的是探讨社会网络的特点，在这个社区接受宫颈癌筛查后的运动。自我中心的社会网络问卷被用来收集社区参与者的横截面网络数据。每个调查参与者（自我）被要求说出他们认识的其他六个女人（改变），并确定他们的关系或关系的性质（家庭，朋友，邻居，其他），住宅亲密度（5公里内），已知的时间长度，通信频率，谈话的主题，以及他们是否借钱给那个人，提供儿童保育或帮助交通。此外，要求每位参与者报告所有已识别的变更之间的关系性质（例如，朋友、家人或邻居）。使用双变量和多变量分析来探索CerviCusco外展筛查活动中接受巴氏试验与社交网络特征之间的关系。双变量结果发现，与未接受巴氏试验的妇女（n = 50）相比，接受巴氏试验的妇女（n = 19）在邻居和家庭的改变组成百分比、平均已知年数、平均密度和平均程度中心性方面存在显著差异（p < 0.05）。最终的逻辑回归模型具有统计学显著性（χ2（2）= 20.911，p < .001）。该模型包括家庭改变组成的百分比和平均密度的变量，并且它解释了巴氏试验收据中37.8%（Nagelkerke R2）的方差，正确分类了78.3%的病例。那些在自我网络中家庭成员比例较高、平均密度较高的妇女在CerviCusco运动中接受巴氏试验的可能性较小。根据这项探索性研究，女性邻居比家庭成员可能提供了一个重要的社会支持来源的医疗保健相关的决定有关接受巴氏试验。未来的研究应收集参与者的纵向社会网络数据，以衡量宫颈癌负担最高的拉丁美洲国家农村土著社区筛查干预措施的网络效应。
Peru has high cervical cancer incidence and mortality rates compared to other Andean countries. Therefore, partnerships between governmental and international organizations have targeted rural areas of Peru to receive cervical cancer screening via outreach campaigns. Previous studies have found a relationship between a person’s social networks and cancer screening behaviors. Screening outreach campaigns conducted by the nonprofit organization CerviCusco created an opportunity for a social network study to examine cervical cancer screening history and social network characteristics in a rural indigenous community that participated in these campaigns in 2012 and 2013. The aim of this study was to explore social network characteristics in this community related to receipt of cervical cancer screening following the campaigns. An egocentric social network questionnaire was used to collect cross-sectional network data on community participants. Each survey participant (ego) was asked to name six other women they knew (alters) and identify the nature of their relationship or tie (family, friend, neighbor, other), residential closeness (within 5 km), length of time known, frequency of communication, topics of conversation, and whether they lent money to the person, provided childcare or helped with transportation. In addition, each participant was asked to report the nature of the relationship between all alters identified (e.g., friend, family, or neighbor). Bivariate and multivariate analyses were used to explore the relationship between Pap test receipt at the CerviCusco outreach screening campaigns and social network characteristics. Bivariate results found significant differences in percentage of alter composition for neighbors and family, and for mean number of years known, mean density, and mean degree centrality between women who had received a Pap test (n = 19) compared to those who had not (n = 50) (p’s < 0.05). The final logistic regression model was statistically significant (χ2 (2) = 20.911, p < .001). The model included the variables for percentage of family alter composition and mean density, and it explained 37.8 % (Nagelkerke R2) of the variance in Pap test receipt, correctly classifying 78.3 % of cases. Those women with higher percentages of family alter composition and higher mean density in their ego networks were less likely to have received a Pap test at the CerviCusco campaigns. According to this exploratory study, female neighbors more than family members may have provided an important source of social support for healthcare related decisions related to receipt of a Pap test. Future studies should collect longitudinal social network data on participants to measure the network effects of screening interventions in rural indigenous communities in Latin American countries experiencing the highest burden of cervical cancer.
