背景来自缅甸的难民食用从当地水体捕获的鱼会增加接触环境污染物的风险。我们使用受访者驱动抽样 (RDS) 对这一难以接触的种群进行抽样，以用于第一个五大湖种群生物监测计划。在当前的研究中，我们检查了访谈数据并评估了 RDS 对独特人群进行抽样的有效性。方法 2013 年，我们使用 RDS 对居住在纽约州布法罗的 205 名缅甸难民和移民进行了抽样，这些难民和移民食用了从五大湖水域捕获的鱼。获得了经 RDS 调整后的社会人口特征、居住史、鱼类消费相关行为以及鱼类咨询意识的人口估计。我们还检查了样本同质性和均衡性，以评估研究中 RDS 假设的满足程度。结果我们的样本在性别、年龄、在布法罗居住的年限、在难民营居住的年限、教育、就业和鱼类消费行为方面具有多样性，并且每个变量在招募结束时都达到了平衡。布法罗的缅甸难民全年食用五大湖的鱼；他们中的大多数人在夏季每周食用鱼两次以上，大约三分之一的人在冬季每周食用当地鱼一次以上。据估计，布法罗的缅甸难民中有 60% 听说过当地的鱼类建议。结论 RDS 有潜力成为对难民和移民进行生物监测和环境暴露评估时采样的有效方法。由于鱼类消费量高以及对鱼类咨询的认识和知识有限，一些难民和移民群体更容易受到环境污染物的影响。这些人群需要提高对当地鱼类咨询的认识。
BackgroundRefugees from Burma who consume fish caught from local waterbodies have increased risk of exposure to environmental contaminants. We used respondent driven sampling (RDS) to sample this hard-to-reach population for the first Biomonitoring of Great Lakes Populations program. In the current study, we examined the interview data and assessed the effectiveness of RDS to sample the unique population.MethodsIn 2013, we used RDS to sample 205 Burmese refugees and immigrants residing in Buffalo, New York who consumed fish caught from Great Lakes waters. RDS-adjusted population estimates of sociodemographic characteristics, residential history, fish consumption related behaviors, and awareness of fish advisories were obtained. We also examined sample homophily and equilibrium to assess how well the RDS assumptions were met in the study.ResultsOur sample was diverse with respect to sex, age, years residing in Buffalo, years lived in a refugee camp, education, employment, and fish consumption behaviors, and each of these variables reached equilibrium by the end of recruitment. Burmese refugees in Buffalo consumed Great Lakes fish throughout the year; a majority of them consumed the fish more than two times per week during summer, and about one third ate local fish more than once per week in winter. An estimated 60% of Burmese refugees in Buffalo had heard about local fish advisories.ConclusionsRDS has the potential to be an effective methodology for sampling refugees and immigrants in conducting biomonitoring and environmental exposure assessment. Due to high fish consumption and limited awareness and knowledge of fish advisories, some refugee and immigrant populations are more susceptible to environmental contaminants. Increased awareness on local fish advisories is needed among these populations.
