Brief summary
Public health study on the nutritional status and eating habits of children and adolescents in Switzerland
Detailed description
This multicentric descriptive cross-sectional observational study, including randomly selected children from 6 to 17 years old living in six regions of Switzerland (Vaud, Bern, Zurich, Luzern, St Gallen, Ticino), provide valuable information on the nutritional status of Swiss children. The aims of this study were to 1) characterize the diet and health behaviors of children and adolescents (who eats what, how much, when, where and with whom); 2) determine the nutritional status, energy and macro- and micro-nutrient intake of children and adolescents; 3) estimate the daily intake of contaminants and other harmful substances; 4) derive population-based national reference values for selected micronutrients and vitamins. It collected high quality representative data on food consumption, dietary and health behaviours (two 24h recalls, which are extensive interviews qualitative and quantitative about the diet of the previous day, and an online questionnaire on food propensity and dietary habits, lifestyle and sociodemographic data) as well as anthropometric and body composition parameters, blood pressure and biological samples (urine spot, optional venous blood).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Dietary intake | baseline | Dietary intake was captured using two 24-hours recalls using GloboDiet, a multi-pass semi-automatic software, as well as a short food propensity questionaire (FPQ). |
| Nutritional biomarkers | baseline | Several nutritional biomarkers will be measured in urine and blood, including blood formula, glycated heamoglobin, lipids (cholesterol types, triglycerides), vitamins (D, B9, B12, beta-caroten), ferritin, calcium. More anaylsis will be performed as the biobanked samples will be analysed, a complete updated list will be available on the study data repository. |
| physical measurements | baseline | weight (kg), height (cm), blood pressure (mmHg), waist and hip circumference (cm) |
| Lifestyle | baseline | A questionnaire containing lifestyle information, including physical activity, screentime, sleep, eating and cooking habits, dietary supplements, health status. The full questionnaire content is available on the data repository website. |
| socio-demographic information | baseline | The questionnaire include information about the household, including parent's education and job type, household size, nationality etc. We also have information from the Federal Office of statistics, including typology of their adress (urban vs rural), a spatial socioeconomic proxy (Swiss-SEP), sex and age of the participant... A complete list is available on the study data repository. |
