PELFI is a multicentre cohort study of migrant families in Spain. The objectives of this manuscript were: 1) to describe the recruitment strategies, data collection and the main socio-demographic characteristics according to geographical origin and sex of participants of the families; and 2) to assess the recruitment and data collection strategies that facilitated participation in the basal assessment of the Badalona and Santa Coloma de Gramanet cohort.
Descriptive study on a convenience sample of migrant and native families residing in Badalona and Santa Coloma de Gramanet. Health interviews were conducted on fathers, mothers and children>16 years; and medical examinations were performed.
There were 115 participating families. Within the recruitment strategies, snow ball achieved 69% cooperation. The cooperation rate of the study was 57.5% and that of the clinical sub-sample was 66.6%. Cooperation rate of the Chinese families was 38.5% and Chinese children >16 years old were not recruited. Twenty-eight percent of the interviews were conducted at weekends or during the evening. Families had a mean of 12.2 years of residence. Seventy-one point two percent of the children >16 years had completed secondary studies. The migrants had lower social class than natives (p < 0.05) and the migrant women had lower levels of education (p < 0.05).
Interacting frequently with the community, using different recruitment strategies simultaneously, incorporating researchers from the same geographical origin as participants, minimising language barriers and offering flexibility in conducting data collection facilitated the participation of the migrant families. The Chinese families presented greater difficulties. The study findings will facilitate the implementation of future cohort studies with similar characteristics.
PELFI是一项针对西班牙移民家庭的多中心队列研究。本论文的目的是：1）根据家庭参与者的地理来源和性别，描述招募策略、数据收集情况以及主要社会人口学特征；2）评估有助于参与巴达洛纳和圣科洛马-德格拉马内特队列基础评估的招募和数据收集策略。
对居住在巴达洛纳和圣科洛马-德格拉马内特的移民家庭和本地家庭的便利样本进行描述性研究。对父亲、母亲和16岁以上的子女进行健康访谈，并进行医学检查。
共有115个参与家庭。在招募策略中，滚雪球式招募实现了69%的合作率。该研究的合作率为57.5%，临床子样本的合作率为66.6%。中国家庭的合作率为38.5%，未招募到16岁以上的中国儿童。28%的访谈在周末或晚上进行。家庭平均居住年限为12.2年。16岁以上的儿童中有71.2%完成了中等教育。移民的社会阶层低于本地人（p<0.05），移民女性的教育水平较低（p<0.05）。
与社区频繁互动、同时使用不同的招募策略、纳入与参与者来自相同地理来源的研究人员、尽量减少语言障碍以及在数据收集方面提供灵活性，促进了移民家庭的参与。中国家庭面临更大困难。研究结果将有助于开展具有类似特征的未来队列研究。
