Repeated covariate measurements bring important information on the time-varying risk factors in long epidemiological follow-up studies. However, due to budget limitations, it may be possible to carry out the repeated measurements only for a subset of the cohort. We study cost-efficient alternatives for the simple random sampling in the selection of the individuals to be remeasured. The proposed selection criteria are based on forms of the D-optimality. The selection methods are compared with the simulation studies and illustrated with the data from the East–West study carried out in Finland from 1959 to 1999. The results indicate that cost savings can be achieved if the selection is focused on the individuals with high expected risk of the event and, on the other hand, on those with extreme covariate values in the previous measurements.

Bayesian subcohort selection for longitudinal covariate measurements in follow‐up studies
Reinikainen, Jaakko; Karvanen, Juha (Wiley-Blackwell, 2022)We propose an approach for the planning of longitudinal covariate measurements in follow-up studies where covariates are time-varying. We assume that the entire cohort cannot be selected for longitudinal measurements due ... -
Efficient design and modeling strategies for follow-up studies with time-varying covariates
Reinikainen, Jaakko (University of Jyväskylä, 2015)Epidemiological studies can often be designed in several ways, some of which may be more optimal than others. Possible designs may differ in the required resources or the ability to provide reliable answers to the questions ... -

Physical fitness and anthropometrics in Finnish soldiers during their early career : prospective changes during a 3-year follow-up
Vaara, J.P.; Pihlainen, K.; Rusila, J.; Ojanen, T.; Kyröläinen, H. (BMJ Publishing, 2023)Introduction: Physical fitness is a fundamental capability required of military personnel, but studies focusing on longitudinal changes in physical fitness and anthropometrics in soldiers are lacking. The aim was to evaluate ...
