背景：Facebook已经显示出作为招募健康研究参与者的经济手段的前景。然而，很少有研究评估这种招募方法在加拿大，更少的仍然针对老年人，而且，据我们所知，没有专门在纽芬兰和拉布拉多（NL.Objective：本研究旨在评估Facebook广告作为一种经济的手段，招募一个代表性的样本，年龄在35至74岁的成年人在NL的横断面健康调查。在2018年4月和5月期间，Facebook广告用于招募基于网络的癌症意识和预防调查;在招募期间，额外的广告有针对性地增加我们确定为在样本中代表性不足的人口统计数据的代表性。将研究样本的社会人口学和健康特征与基础人群的分布进行比较，以确定代表性。Cramer V表示样本和总体分布之间的差异大小，解释为小（Cramer V=0.10），中（0.30）和大（0.50）。如果分布没有统计学显著差异（卡方P>.01）或差异很小（V
Background: Facebook has shown promise as an economical means of recruiting participants for health research. However, few studies have evaluated this recruitment method in Canada, fewer still targeting older adults, and, to our knowledge, none specifically in Newfoundland and Labrador (NL).Objective: This study aimed to assess Facebook advertising as an economical means of recruiting a representative sample of adults aged 35 to 74 years in NL for a cross-sectional health survey.Methods: Facebook advertising was used to recruit for a Web-based survey on cancer awareness and prevention during April and May 2018; during recruitment, additional advertisements were targeted to increase representation of demographics that we identified as being underrepresented in our sample. Sociodemographic and health characteristics of the study sample were compared with distributions of the underlying population to determine representativeness. Cramer V indicates the magnitude of the difference between the sample and population distributions, interpreted as small (Cramer V=0.10), medium (0.30), and large (0.50). Sample characteristics were considered representative if there was no statistically significant difference in distributions (chi-square P>.01) or if the difference was small (V
