Associations between genetic variants associated with body mass index and trajectories of body fatness across the life course: a longitudinal analysis.


ABSTRACT: Background:The genetic associations with trajectories of body fatness over the life course remain unknown. Methods:We used a group-based modelling approach to identify trajectories of body fatness from age 5 years up to 65 for 7277 women from the Nurses' Health Study and 4645 men from the Health Professionals Follow-up Study. We created a genetic risk score (GRS) based on 97 variants associated with adulthood body mass index (BMI) and estimated its association with trajectories using logistic regression. Results:We identified four distinct trajectories: lean-medium, medium-medium, lean-heavy and medium-heavy. The GRS increased across the four groups in that order (P?
