The Finnish Twin Cohort Study: an update
1Department of Public Health, University of Helsinki, Helsinki, Finland. jaakko.kaprio@helsinki.fi
Summary
The Finnish Twin Cohort provides valuable longitudinal data for health research. Twin mortality rates are comparable to the general population, supporting ongoing genetic and environmental studies.
Area of Science:
- * Twin studies
- * Population genetics
- * Longitudinal research
Background:
- * The Finnish Twin Cohort comprises three distinct cohorts established between the 1970s and 1990s.
- * Previous reviews in 2002 and 2006 detailed the cohort's structure and initial findings.
- * This review updates on recent data collection efforts and ongoing research.
Purpose of the Study:
- * To provide an update on the latest data collections within the Finnish Twin Cohort.
- * To report on mortality analyses within the older twin cohort.
- * To highlight ongoing and planned sub-studies utilizing the cohort data.
Main Methods:
- * Longitudinal data collection across multiple waves for established cohorts.
- * Mortality analysis of the older cohort (born before 1958) from 1975 to 2009.
- * Inclusion of spouses/partners in recent data collection waves (Finntwin16).
Main Results:
- * Recent data collection includes fourth waves for the older cohort and Finntwin12, and a fifth wave for Finntwin16.
- * Mortality analysis indicates adult twins do not have differing mortality rates compared to the general population.
- * Numerous sub-studies with detailed phenotyping and omics data are underway.
Conclusions:
- * The Finnish Twin Cohort continues to be a vital resource for population-based, longitudinal research.
- * Ongoing data collection and sub-studies enhance its utility for investigating genetic and environmental influences on health.
- * The cohort's findings contribute to national and international research collaborations.

02:20Longitudinal Research
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...
01:26Longitudinal Studies
Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...
01:29Bias in Epidemiological Studies
Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

There are many research methods available to psychologists in their efforts to understand, describe, and explain behavior and the cognitive and biological processes that underlie it.
01:20Study Designs in Epidemiology
Epidemiological study designs are fundamental tools for investigating the distribution, determinants, and control of health conditions in populations. They help researchers understand the relationships between exposures and outcomes, and they broadly fall into two categories: "observational" and "experimental" studies.
Observational studies are those where the researcher does not intervene but rather observes natural variations. They include cross-sectional, cohort, and case-control studies.

01:15Bioavailability Study Design: Healthy Subjects Versus Patients
Bioavailability studies are essential for evaluating a drug's therapeutic efficacy and understanding its absorption patterns under various physiological conditions. Conducting such studies on target patient populations provides more relevant data by simulating real-world disease states. However, practical challenges often necessitate the use of young, healthy adult volunteers as study subjects.Patients may exhibit altered drug absorption patterns due to the effects of the disease itself,...
