  • Results displayed as OR and 95% CI, statistically significant results printed in bold.

  • Results are derived from multinomial logistic regression models adjusted for sex, age, education, body mass index (BMI), physical activity, smoking, recall season, recall weekday and weighted for age group, sex, marital status, major region of Switzerland, nationality, household size, season and weekday according to the menuCH weighting strategy.34 p for trend was calculated by using the medians of the UPF quartiles as continuous variable in the multinomial logistic regression model.

  • d, day; Q, quartile; UPF, ultraprocessed food.
