Based on ethnographic interviews among working-class women from Mexico City, our primary aim was to identify themes related to diet and sleep among midlife women.

Ethnographer field notes and transcripts were analyzed using thematic analysis. Guided by findings from the interviews demonstrating that tea consumption might be associated with sleep, we conducted <jats:italic>post-hoc<\/jats:italic> analyses of the relationship between tea and sleep duration using data from food frequency questionnaires and actigraphy, respectively, in the broader cohort (<jats:italic>n<\/jats:italic> = 406).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The mean (SD) age of the ethnographic sample was 50.0 (9.0) years. The top noted theme was the use of herbal tea (in Spanish <jats:italic>infusion<\/jats:italic>) to improve sleep; most women (29\/30) discussed herbal teas, characterizing them as a \u201cnatural remedy\u201d to facilitate sleep. The mean (SD) age of the broader sample (<jats:italic>N<\/jats:italic> = 406) was 48.4 (6.2) years. <jats:italic>Post-hoc<\/jats:italic> analyses revealed positive associations between tea without sugar (though not necessarily herbal tea) and sleep duration.
