Studies in the fields of occupational medicine or public health are often conducted as multicenter studies. This results in a nested data structure. Hierarchically structured data are obtained when the study cohort encloses different groups (e.g., geographical or temporal distance from exposure). If the effects of exposure to pollutants/hazardous substances or effects of health interventions are defined as endpoints, it is often appropriate to repeat the measurements after time in order to capture a longitudinal course of the effect parameters. I think all of us have been confronted with the problem of correctly mapping such data in a statistical model. Unfortunately, we notice from time to time that researchers take the easy way out and evaluate such data in a cross-sectional view. The nested structure of the data is often neglected. Information contained in the data is not used, and an opportunity is missed. Modern statistics, however, offer a variety of possibilities to meet these challenges. By adapting the study design (crossover design, subtraction of repeated measurements, etc.), it is sometimes also possible to facilitate the correct handling of the data. The goal of this Special Issue is to provide examples from different research areas to illustrate the possibilities of analyzing and handling hierarchical, nested, and/or longitudinal data in the community and to contribute to the exchange of ideas.
I look forward to your contributions.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Environmental Research and Public Health is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2300 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
