In the example of around three situations (desserts, meals and seafood), high-frequency is actually defined as several times a day/daily/a few times weekly instead of low frequency step 1–fourfold 30 days/never ever. The new means is actually considering pre-established food regularity questionnaires, adapted toward analysis and you may included in early in the day books . Both the deal with and you will content validity of your tool was basically determined by the grounding brand new questionnaire towards the literary works remark.

When country and sex were considered simultaneously, logistic regression with main effects of country and sex and their interaction was conducted to obtain significance tests. When the interaction was not significant, it was removed and the model was re-estimated using main effects only. Third, the effects of not living at parental home on the consumption of the food groups were assessed in logistic regression models. Each sex-country combination was recoded into a new variable yielding 8 distinct groups.
