Pennington Center Longitudinal Study (PCLS)

This is an observational study called the Pennington Center Longitudinal Study (PCLS). It's designed to follow a large group of volunteers over time to understand how health behaviors change and how health problems develop. Researchers will use existing data collected over the past 20 years from other studies at the Pennington Biomedical Research Center. You can join if you are 18 years or older and volunteer to participate. The main goal is to analyze this collected data over twenty years to understand health trends. The current status of this study is unclear.

Study design
This is an observational study with a planned enrollment of 30,000 participants. It is not a randomized study and the phase is not specified.
What's involved
The only specific protocol mentioned is the collection of a blood sample for risk factor determination and storage, if not already done in a previous study.
Compensation
Not stated in the trial record.
Follow-up
The primary endpoint involves cross-sectional analyses of a database measured at twenty years.

    The only protocol specific to the PCLS study is the collection of blood sample for risk factor determination and storage in the PBRC archive bank, only to be invoked in cases where studies do not include a blood draw as part of their protocol. The PCLS represents an effort to utilize a data collection over the last twenty years during the clinical research studies for cross-sectional analyses, as well as followed prospectively for the development of a variety of health-related outcomes.
