No bonuses have been given. Brand new reaction rates (predicated on quantities of returned forms) was >95% (Bulgaria, Poland), 92% (Denmark), and you may ranged (60%–100%) to own Germany depending on the surveyed teams (85% typically, down effect costs within the highest lecture rooms compared to faster seminars). The analysis included 2651 professionals. Gender try destroyed for 60 children and you may an additional 189 got shed answers in a number of issues leading to a final attempt dimensions out of 2402.
A lunch regularity questionnaire (9 sign details) analyzed consumption patterns out of candy; cakes/cookies; edibles and you can punctual/canned eating; berries; intense and prepared make and you may salads; and you can meat and you will fish (see Desk 1).

Regarding about three points (cakes, ingredients and you may fish), high-frequency is actually defined as on a daily basis/daily/several times per week versus low-frequency 1–fourfold 1 month/never. The fresh new appliance is centered on pre-present food frequency surveys, adjusted to the data and you will found in past courses . Both the deal with and stuff validity of the software had been ascertained by grounding the latest survey to the literature remark. No formal decide to try out-of validity was did, nevertheless the survey is actually much like most other eating frequency surveys that had been confirmed, age.grams. [25, 26].

First, the sociodemographic characteristics of the sample were presented by country and tested for differences using chi-square test. Bivariate comparisons were tested by chi-square test. 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. The interaction between this new variable and living at parental home versus other living arrangements indicated whether the effects were homogenous or varied across countries or by sex.
