A surveillance source of tobacco use differences among immigrant populations
- View All
INTRODUCTION: Tobacco use disproportionately affects some ethnic minority populations. Important gains in understanding the relationship between acculturation and tobacco use have been hindered by the lack of available data, large samples of specific immigrant groups. This study is among the first to use electronic medical record (EMR) data to examine differences in tobacco use associated with acculturation among various population groups. METHODS: Relevant variables for all medical group patients aged 18 years and older with clinician visits were extracted from the EMR of one large medical group from March 2006 to February 2007. Preferred language and country of origin data from the EMR were used to create distinct cultural groupings. Adjusted prevalences were computed. RESULTS: One hundred thousand [corrected] three hundred [corrected] twenty nine patients reported [corrected] languages as English, Hmong, Vietnamese, Oromo, Amharic, Somali, and Spanish and were categorized as U.S. born or non-U.S. born. After adjusting for age, utilization, and insurance status, more acculturated Mexican and Hmong women were more likely to be tobacco users compared with less acculturated women. Among non-English speaking, current tobacco use was more prevalent among men compared with women. DISCUSSION: Interpreted language and country of origin data collected in a clinical setting were useful for describing tobacco use differences between and within cultural groups. Using preferred language and country of origin as a proxy for acculturation status may help understand some of the within and between cultural differences in tobacco use. These novel data sources have potential usefulness for tobacco surveillance of relatively small cultural groups.
