Differences in Fat Mass Estimation Formulas in Physically Active Adult Population and Relation With Skinfold Sums.
An observational study of Body Weight Changes and Body Weight, run by Universidad Católica San Antonio de Murcia.
Trial summary
The objective of the present study was to analyze the differences between the formulas used to estimate fat mass and to establish the existing relationship with the skinfold sum in anthropometry. A total of 2,458 active subjects participated in the study (mean age: 27.98±7.43 years-old). Read more about this study

About this study
The objective of the present study was to analyze the differences between the formulas used to estimate fat mass and to establish the existing relationship with the skinfold sum in anthropometry. A total of 2,458 active subjects participated in the study (mean age: 27.98±7.43 years-old). Basic measurements and skinfolds variables were measured following the guidelines of the International Society for the Advancement in Kinanthropometry (ISAK), and Kerr, Durnin-Womersley, Faulkner and Carter equations were used to assess fat mass. Significative differences were found between all the formulas for the percentage of fat mass and the fat mass in kilograms. The correlations among the skinfolds sums and the different equations were high and significative in all the cases. There were differences between all the formulas used to estimate the fat mass. The six or eight skinfold sums could be a valid and better alternative than the fat mass equations or the BMI to assess the subcutaneous fat mass in physically active adults.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

A total of 2,458 active subjects participated in the study (mean age: 27.98±7.43 years-old).

Questions about this trial
What is this clinical trial studying?
An observational study of Body Weight Changes and Body Weight, run by Universidad Católica San Antonio de Murcia.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 12 Jun 2020. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Fat mass weight (time frame: 6 years). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Jun 2020; AzTrials last refreshed its copy on 28 Oct 2026.
