Two sample Mendelian Randomisation using an outcome from a multilevel model of disease progression
Two sample Mendelian Randomisation using an outcome from a multilevel model of disease progression

This paper introduces a multivariate two-sample Mendelian Randomisation approach using a multilevel model to identify the causal effect of an exposure on both the initial severity and rate of change of a disease progression trajectory.

Combining longitudinal data from different cohorts to examine the life-course trajectory
Combining longitudinal data from different cohorts to examine the life-course trajectory

This paper introduces a method for generating continuous life course trajectories by combining data from multiple studies, demonstrating how to handle challenges like data harmonisation and missing data by using an example that models children's weight.

Air and noise pollution exposure in early life and mental health from adolescence to young adulthood
Air and noise pollution exposure in early life and mental health from adolescence to young adulthood

In this longitudinal cohort study, early-life air and noise pollution exposure were prospectively associated with 3 common mental health problems from adolescence to young adulthood.

Cross-cohort change in parent-reported emotional problem trajectories across childhood and adolescence in the UK
Cross-cohort change in parent-reported emotional problem trajectories across childhood and adolescence in the UK

This study in two UK cohorts found that young people born in the early 2000s experienced an earlier onset and steeper trajectory of emotional problems compared to those born a decade earlier.

Long-term cardiometabolic health in people born after assisted reproductive technology: a multi-cohort analysis
Long-term cardiometabolic health in people born after assisted reproductive technology: a multi-cohort analysis

This meta-analysis and trajectory modelling study found similar blood pressure, heart rate, and glucose measures in individuals conceived after ART compared with those born after unassisted conception.
