Summary
This study successfully followed up Australian Aboriginal Birth Cohort participants 20 years after recruitment, demonstrating high retention rates. The findings support continued life course research in this population.
Area of Science:
- Epidemiology
- Public Health
- Indigenous Health
Background:
- Established in 1987, the Australian Aboriginal Birth Cohort study investigates fetal and childhood growth's link to chronic adult diseases.
- The cohort, from a marginalized population, also serves as a valuable resource for descriptive and analytical studies.
- This paper details the methodology of the third follow-up, conducted 20 years post-birth recruitment.
Purpose of the Study:
- To describe the processes and outcomes of the third follow-up of the Australian Aboriginal Birth Cohort.
- To assess the feasibility of continued life course research in this population.
Main Methods:
- A multiphase protocol with modifications for rural and urban settings was employed for participant tracing.
- The protocol aimed to overcome challenges associated with tracking individuals in remote areas.
Main Results:
- Out of 686 initial participants, 68 were untraced and 27 had died.
- Of 591 available, 122 were not examined due to refusals or logistical issues (weather, mobility, remote locations).
Conclusions:
- The high retention rate (approximately 80% of those available) highlights the effectiveness of the multiphase tracing protocols and researcher dedication.
- The positive community relations and goodwill are crucial for the study's success.
- Continued follow-up at age 25 years is planned, indicating the study's ongoing feasibility.

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...
00:57Population Growth
Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.However, realistic environmental conditions limit the number of...
01:08Data Collection by Observations
Data collection refers to a systematic way of obtaining, observing, measuring, and analyzing accurate information. Observational studies are one of the most widely used methods of data collection. It involves collecting data by observing the behavior and physical characteristics of a sample without making any modifications to the sample.

01:27Emerging Adulthood
Jeffrey Arnett's concept of emerging adulthood offers a framework to understand the unique developmental stage between adolescence and full-fledged adulthood, generally from ages 18 to 25. This period is marked by extensive exploration and shifts in identity, relationships, and career choices, a process known in psychology as role experimentation. Emerging adulthood reflects the evolving cultural expectations surrounding adulthood and the dynamic process of personal transformation during this...
01:50Cross-Sectional Research
In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...
