目的随着中国经济的快速发展，数以百万计的农村居民涌入城市就业，造成了大量的留守儿童（LBC）。与此同时，麻疹疫情继续发生，但父母移徙对儿童疫苗接种状况的影响在很大程度上是未知的。在调整家庭社会经济地位（SES）指标后，本研究旨在评估父母迁移与中国农村儿童及时接种麻疹疫苗之间的关系。方法采用多阶段抽样方法对广西农村18-54月龄儿童进行横断面调查。从儿童的疫苗接种证书中获得麻疹疫苗接种状况的信息，并通过采访儿童的主要监护人收集有关SES的数据。采用加权logistic回归比较LBC和非留守儿童（NLBC）的家庭经济地位和疫苗接种覆盖率，采用Kaplan-Meier生存分析比较疫苗接种延迟。结果1216名儿童中，46%为LBC， 54%为NLBC。与NLBC相比，LBC的麻疹疫苗及时接种覆盖率明显较低，中位延迟时间更长。在对SES指标进行调整后，LBC患者首次接种麻疹疫苗时未及时接种的可能性明显高于NLBC患者（OR = 1.33, 95% CI = 1.02-1.75）。结论受父母迁移和家庭经济地位的负面影响，农村LBC儿童更容易出现严重的麻疹疫苗接种延误。优化疫苗接种政策可促进农村LBC人群及时接种疫苗。
ObjectiveWith the rapid economic development in China, millions of rural residents are migrating to the cities to gain employment, resulting in numerous left-behind children (LBC). Simultaneously, outbreaks of measles continue to occur, yet the effect of parental migration on children's vaccination status is largely unknown. This study aimed to evaluate the association between parental migration and children's timely measles vaccination in rural China, after adjusting for family socio-economic status (SES) indicators.MethodsWe conducted a cross-sectional survey using multistage sampling among children aged 18-54 months in rural Guangxi of China. Information on measles vaccination status was obtained from the child's vaccination certificate, and data on SES were collected by interviewing the child's primary guardian. Family SES and vaccination coverage were compared between LBC and non-left-behind children (NLBC) using weighted logistic regression, while the delay in vaccination was compared using Kaplan-Meier survival analysis.ResultsOf the 1216 study children, 46% were LBC and 54% were NLBC. Compared to NLBC, the coverage of timely measles vaccination was significantly lower, and the median delay period was longer among LBC. After adjusting for SES indicators, LBC were significantly more likely to have an untimely vaccination for their first dose of measles vaccine than NLBC (OR = 1.33, 95% CI = 1.02-1.75).ConclusionsDue to the negative effect of parental migration and family SES, LBC were more likely to encounter serious delays of measles vaccination in rural China. Optimising vaccination policies could facilitate timely vaccination among LBC in rural China.
