Understanding the Utilization of Qualitative Inquiry in Public Health Nutrition Research

Abstract

Qualitative inquiry, often characterized by non-numerical data, remains an underutilized tool in various research spheres including public health nutrition. However, there is an existing shared common ground with quantitative research, in that qualitative research can be a useful complementary tool in explaining the underlying meanings of quantitative data by unpacking the complexities of human behaviour and its relation to disease. Moreover, the qualitative approach is often commended for humanizing research by creating a space for the voices and contributions of the participants. Despite such perceived benefits, the position and relevance of qualitative researchers, techniques, and findings in the body of knowledge continue to be questioned and undervalued. Divergent views on the validity and reliability of qualitative research persist.  Consequently, the use of qualitative research methods and the publication of qualitative evidence remain limited in the natural sciences, including public health nutrition. This paper discusses qualitative research--its definition, research design, importance and relevance. Additionally, using specific examples, this paper will elucidate the possibilities and challenges of using qualitative techniques and marrying qualitative and quantitative methodologies in public health nutrition research.
