Association between a pro-inflammatory dietary pattern during pregnancy and type 1 diabetes risk in offspring
BACKGROUND: Immune-mediated processes leading to childhood type 1 diabetes may begin in fetal life. We hypothesised that a maternal inflammatory diet during pregnancy increases offspring risk of type 1 diabetes. METHODS: The Danish National Birth Cohort (DNBC) was recruited during 1996-2002. Maternal Empirical Dietary Inflammatory Index score (EDII-score) was calculated from a comprehensive 360-item self-administered food frequency questionnaire …
Harmonization of Human Biomonitoring Studies in Europe
Human biomonitoring has become a pivotal tool for supporting chemicals' policies. It provides information on real-life human exposures and is increasingly used to prioritize chemicals of health concern and to evaluate the success of chemical policies. Europe has launched the ambitious REACH program in 2007 to improve the protection of human health and the environment. In October 2020 the EU commission published its new chemicals strategy for sust…
Development of a dietary screening questionnaire to predict excessive weight gain in pregnancy
Excessive gestational weight gain (GWG) is a risk factor for several adverse pregnancy outcomes, including macrosomia. Diet is one of the few modifiable risk factors identified. However, most dietary assessment methods are impractical for use in maternal care. This study evaluated whether a short dietary screening questionnaire could be used as a predictor of excessive GWG in a cohort of Icelandic women. The dietary data were collected in gestati…
Potential Health Risk of Endocrine Disruptors in Construction Sector and Plastics Industry
Endocrine disruptors (EDs) belong to large and diverse groups of agents that may cause multiple biological effects associated with, for example, hormone imbalance and infertility, chronic diseases such as diabetes, genome damage and cancer. The health risks related with the exposure to EDs are typically underestimated, less well characterized, and not regulated to the same extent as, for example, carcinogens. The increased production and utilizat…
Missing portion sizes in FFQ – alternatives to use of standard portions
Objective Standard portions or substitution of missing portion sizes with medians may generate bias when quantifying the dietary intake from FFQ. The present study compared four different methods to include portion sizes in FFQ. Design We evaluated three stochastic methods for imputation of portion sizes based on information about anthropometry, sex, physical activity and age. Energy intakes computed with standard portion sizes, defined as sex-sp…
Fruit and vegetable consumption in a sample of 11-year-old children in ten European countries – the PRO GREENS cross-sectional survey
Objective To describe fruit and vegetable intake of 11-year-old children in ten European countries and compare it with current dietary guidelines. Design Cross-sectional survey. Intake was assessed using a previously validated questionnaire containing a pre-coded 24 h recall and an FFQ which were completed in the classroom. Portion sizes were calculated using a standardized protocol. Setting Surveys were performed in schools regionally selected i…
Does eating family meals and having the television on during dinner correlate with overweight? A sub-study of the PRO GREENS project, looking at children from nine European countries
Objective Family meals have been negatively associated with overweight in children, while television (TV) viewing during meals has been associated with a poorer diet. The aim of the present study was to assess the association of eating family breakfast and dinner, and having a TV on during dinner, with overweight in nine European countries and whether these associations differed between Northern and Southern & Eastern Europe. Design Cross-section…
Sociodemographic characteristics and food habits of organic consumers – a study from the Danish National Birth Cohort
Objective To develop a basis for building models that can examine the impact of organic food (OF) choices on maternal and offspring health, including identification of factors associated with OF consumption and underlying dietary patterns. Design Dietary intake was collected for the preceding month from an FFQ in mid-pregnancy and information on sociodemographic characteristics was collected from telephone interviews during pregnancy. From a ques…
