Culturally targeted, informal social networking approaches to improving disaster preparedness have not been empirically tested.
In partnership with community health promoters and the Los Angeles County Department of Public Health, this study tested a disaster preparedness program for Latino households.
This study had a community-based, randomized, longitudinal cohort design with two groups and was conducted during February-October 2007. Assessments were made at baseline and 3 months. Analyses were carried out January-October 2008.
SETTINGS/PARTICIPANTS: Community-based study of 231 Latinos living in Los Angeles County.
Participants were randomly assigned to attending platicas (small-group discussions led by a health promoter/promotora de salud) or receiving "media" (a culturally tailored mailer). A total of 187 (81.0%) completed the 3-month follow-up.
A self-reported disaster preparedness checklist was used.
Among participants who did not have emergency water pre-intervention, 93.3% of those in the platica arm had it at follow-up, compared to 66.7% in the media arm (p=0.003). Among participants who did not have food pre-intervention, 91.7% in the platica arm reported it at follow-up, compared to 60.6% in the media arm (p=0.013). Finally, among participants who did not have a family communication plan pre-intervention, 70.4% in the platica arm reported one at follow-up, compared to 42.3% in the media arm (p=0.002).
Although both arms improved in stockpiling water and food and creating a communication plan, the platica arm showed greater improvement than the media group.
针对文化差异、采用非正式社交网络方法来提高备灾能力，尚未经过实证检验。
与社区卫生促进者和洛杉矶县公共卫生部合作，本研究测试了针对拉丁裔家庭的备灾计划。
本研究采用了社区为基础的、随机的、纵向队列设计，分为两组，于 2007 年 2 月至 10 月进行。在基线和 3 个月时进行评估。分析于 2008 年 1 月至 10 月进行。
地点/参与者：在洛杉矶县居住的 231 名拉丁裔人群参与了社区为基础的研究。
参与者被随机分配参加小组讨论（由健康促进者/促进者主持的小型讨论）或接受“媒体”（针对文化的邮件宣传）。共有 187 人（81.0%）完成了 3 个月的随访。
使用自我报告的备灾清单。
在干预前没有应急水的参与者中，小组讨论组有 93.3%在随访时有应急水，而媒体组有 66.7%（p=0.003）。在干预前没有食物的参与者中，小组讨论组有 91.7%在随访时有食物，而媒体组有 60.6%（p=0.013）。最后，在干预前没有家庭沟通计划的参与者中，小组讨论组有 70.4%在随访时有沟通计划，而媒体组有 42.3%（p=0.002）。
尽管两组在储备水和食物以及制定沟通计划方面都有所改善，但小组讨论组的改善程度大于媒体组。
