Design outcomes

Primary

Measure	Time frame
A posteriori dietary patterns are not directly measured, but are calculated based on the questionnaires that participants to the MONICA and NFP1A studies had to fill out, which included a simplified 24-hour recall checklist (from this information, we use the diets of the overall population to cluster diets into coherent patterns, the so-called dietary patterns). The questionnaires are answered at study entry (which spans from 1977 to 1992, depending on whether we talk about NFP1A or MONICA).	—

Secondary

Measure	Time frame
1. Association between dietary patterns and demographic (age, sex, language region of residence, nationality), socioeconomic (education), morphologic (BMI) and behavioural (smoking, physical activity) factors are measured using testing whether the distribution (for continuous variables) or the proportion of categories (for qualitative variables) differ from those obtained from the rest of the population, using v-test as previously described at study entry 2. Mortality hazard ratio for groups of individuals following different dietary patterns is measured using Cox proportional hazards regression models at the most recent update of the Swiss National Cohort (30.06.2016)	—
