What's in the refrigerator? Using an adapted material culture approach to understand health practices and eating habits in the home

Health researchers have long acknowledged the limitations of self-reporting in studies of health in the home and have consequently sought various methods to broaden research beyond self-reporting in efficient and productive ways. Our two independent research studies, one in Copenhagen, Denmark (2015), and one in Providence County, Rhode Island, in the United States (2015–2016), illustrate how health researchers can adapt an everyday material culture approach used in anthropology to fit the needs of health and wellbeing studies, particularly when it comes to home-based research on health behavior. Our two studies both utilized one particular household object—the refrigerator—to help explore everyday eating habits in various types of households. By analyzing these separate studies together, we found that using the refrigerator in object-elicitation exercises and photographing the refrigerator provided insights that enhanced the interview process, thereby efficiently addressing some of the limitations of interviews and self-reporting. We also found that the refrigerator was a useful comparative tool both within our individual studies and across our research contexts. We conclude that the refrigerator and other everyday use objects are useful methodological tools in health-related studies in the home, and propose that regularly utilizing the refrigerator may help researchers interpret qualitative data about nutrition and eating habits.
