Background: Double-blind placebo-controlled food challenge (DBPCFC) is widely regarded as the "gold standard" to diagnose food allergy. Maximum efforts are made to reduce bias, yet DBPCFCs are costly, time-, and resource-intensive. Less demanding open food challenges are increasingly used in clinical practice.

Objective: We aimed to investigate genetic susceptibility to FA in an adult population and to assess the association between secondary FA and allergic rhinitis (AR).
Methods: FA and allergen-specific FA were defined based on in-depth questionnaires and a previously published FA algorithm in the Lifelines.
Background: Asthma is associated with impaired lung function; however, it is uncertain if a lower childhood lung function is associated with asthma onset and persistence during adolescence. The aims of the present study were to investigate the association between childhood lung function and onset and persistence of asthma during adolescence.
Methods: In the population-based BAMSE (Sweden), PIAMA (Netherlands) and MAAS (UK) birth cohorts, we analysed the association of forced expiratory volume in 1 s (FEV), forced vital capacity (FVC), FEV/FVC and forced expiratory volume at 75% of FVC at age 8 years with asthma onset and persistence in adolescence (age 12-16 years) using cohort-specific logistic regression analysis followed by meta-analysis.
Background: Multimorbidity is linked to poor quality of life, and increased healthcare costs, and multimorbidity risk is potentially mitigated by a healthy lifestyle. This study evaluated the individual and joint contributions of an extensive set of lifestyle factors to the development of multimorbidity.
Methods: A prospective study of 133,719 adults (age 45.
