Measles vaccination is important to prevent outbreak, and social capital can be an important preventive factor. However, there have been very few studies that investigated the association between social capital and measles vaccination, especially the second dose, which is more likely to be suboptimal. This study aimed to investigate the association between social capital and second dose of measles vaccine.
Data were derived from a population-based study of first-grade elementary school children (6-7 years old) in Adachi City, Tokyo. Caregivers were asked to complete a questionnaire, and 4291 of them provided a valid response (response rate: 80.1%). Among these 4291 valid responses, 69 responses were excluded since variables for social capital measures were missing, which resulted in analytic sample size of 4222. We analyzed the association between measles vaccination and social capital including social ties, social trust and mutual aid by multilevel logistic regression analysis with a random intercept model.
About 8.9% of the children did not receive a second dose of measles-containing vaccines. After covariates adjustments, increase of one-standard-deviation of poor individual-level social ties showed 11% lower odds of receiving measles-containing vaccines (OR: 0.89, 95% CI: 0.80-0.99). By contrast, no significant association between community-level social ties and measles vaccination was found. Regarding social trust, no significant association between individual-level social trust and measles vaccination was found. However, increase of one-standard-deviation of poor community-level social trust showed 11% lower odds of receiving measles-containing vaccines (OR: 0.89, 95% CI: 0.79-0.998). There was no association between mutual aid and measles vaccination.
Social ties and social trust were associated with second dose of measles vaccination. Fostering social capital may be effective in raising the low rate of second dose of measles vaccine.
麻疹疫苗接种对于预防麻疹爆发非常重要，而社会资本可能是一个重要的预防因素。然而，很少有研究调查社会资本与麻疹疫苗接种之间的关系，特别是第二剂疫苗，其接种情况更有可能不理想。本研究旨在调查社会资本与麻疹疫苗第二剂接种之间的关系。
本研究的数据来自于东京足立区一年级小学生（6-7 岁）的一项基于人群的研究。要求照顾者填写一份问卷，其中 4291 人提供了有效回复（回复率：80.1%）。在这 4291 份有效回复中，由于社会资本测量变量缺失，有 69 份被排除在外，因此分析样本量为 4222 份。我们通过多水平逻辑回归分析和随机截距模型分析了麻疹疫苗接种与社会资本（包括社会联系、社会信任和互助）之间的关系。
约有 8.9%的儿童未接种第二剂含麻疹疫苗。调整了混杂因素后，个体层面较差的社会联系每增加一个标准差，接种含麻疹疫苗的几率降低 11%（OR：0.89，95%CI：0.80-0.99）。相比之下，社区层面的社会联系与麻疹疫苗接种之间没有显著关联。关于社会信任，个体层面较差的社会信任与麻疹疫苗接种之间没有显著关联。然而，社区层面较差的社会信任每增加一个标准差，接种含麻疹疫苗的几率降低 11%（OR：0.89，95%CI：0.79-0.998）。互助与麻疹疫苗接种之间没有关联。
社会联系和社会信任与麻疹疫苗第二剂接种有关。培养社会资本可能有助于提高麻疹疫苗第二剂的接种率。
