Visual methods in the assessment of diet intake in Mexican American women.

Assessment of dietary intake is based largely on self-report or use of biomarkers. However, neither self-report nor biomarkers inform nurses of patterns in dietary intake in the context of gender, culture, and ethnicity. This article describes the relevance of visual methods focusing on the context of dietary intake in Mexican American women, illustrated by a formative study. A qualitative, descriptive, methodological design incorporating photo elicitation was used. The sample consisted of 7 Mexican American women, who took photographs of their food intake, food preparation, and context of food consumption, such as family gatherings, which were then described by the women. Data included participant photographs, the descriptions of why each image was obtained, and stories about the photographs. Visual methods were found to be a relevant and important addition to traditional dietary assessment methods, to enhance gender, cultural, and contextually relevant assessment of dietary intake in Mexican American women.
