Researchers are launching an anthropometric study in the Bauska region this summer to analyze current body parameters and compare them with historical data from the 1930s. The project, which involves measurements and 3D scanning, aims to document “centennial shifts” in the Latvian population, reflecting changes in socio-economic conditions, nutrition, and lifestyle over the last century.
Historical context of the study
The current project builds upon the work of Professor Jākobs Primanis (1892–1971), a physician and anatomist who pioneered anthropology in Latvia. During the 1920s and 1930s, Primanis led expeditions that surveyed approximately 35,000 people to define the anthropological characteristics of Latvians. Much of this historical data, including photographic films and questionnaires from sites like Mežotne, was left unprocessed for decades due to World War II and subsequent occupations. In 2023, the University of Stradins (RSU) in Riga completed the digitization of over 10,000 of these questionnaires, allowing researchers to finally utilize the information for long-term population analysis.
Measurement locations and schedule
The research team has scheduled data collection sessions in two Bauska region locations. In Mežotne, measurements will take place at the Mežotne Palace on June 29 from 15:00 to 19:00 and June 30 from 10:00 to 19:00. The team will then relocate to the Bauska City Primary School, where sessions are scheduled for July 1 (15:00–19:00), July 2–4 (10:00–19:00), and July 5 (9:00–14:00).
Participation requirements and privacy
The study is open to residents of all ages, and registration at a specific location is not required. Parents or guardians must accompany children and adolescents up to 17 years old to provide informed consent. To ensure privacy during 3D scanning and anthropometric measurements, the team has provided isolated booths for participants to remove outer clothing. According to project guidelines, full-size color 3D scans are stored on secure servers exclusively for scientific use.
What comes next for the project?
The project is part of a broader initiative targeting approximately 2,000 participants across Latvia by 2026. Following the initial data collection, participants can expect to receive their anthropometric results immediately, with black-and-white 3D scans delivered via email. Looking ahead, the project team plans to host outreach events in the spring of 2027 to present summarized regional findings. Additionally, adult participants who provide blood samples for population genetics research may begin receiving individual feedback on those results starting in 2028.
Frequently Asked Questions
Who can take part in the genetic research?
Only adults aged 18 and over are eligible to provide a blood sample for the population genetics study.
Do I need to be a local resident of Bauska to participate?
No, registration at a specific location is not required, although local residents are especially encouraged to attend.
What kind of feedback will I receive from the study?
Participants receive their anthropometric data immediately on-site and can request a black-and-white 3D scan via email. Long-term feedback regarding genetic analysis is planned for 2028.
How do you think your own physical development might reflect the nutritional and environmental changes of the last few decades?
