Editing Body mass index (section)

=== Surface-based body shape index ===
The Surface-based Body Shape Index (SBSI) is far more rigorous and is based upon four key measurements: the [[body surface area]] (BSA), vertical trunk circumference (VTC), waist circumference (WC) and height (H). Data on 11,808 subjects from the National Health and Human Nutrition Examination Surveys (NHANES) 1999–2004, showed that SBSI outperformed BMI, waist circumference, and [[Body Shape Index|A Body Shape Index]] (ABSI), an alternative to BMI.<ref>{{Cite web | vauthors = Pomeroy R | date = 29 December 2015 |title = A New Potential Replacement for Body Mass Index {{!}} RealClearScience|url = http://www.realclearscience.com/journal_club/2015/12/30/a_new_potential_replacement_for_body_mass_index_109492.html|website = realclearscience.com|access-date = 2015-12-31|url-status=live|archive-url = https://web.archive.org/web/20160101113606/http://www.realclearscience.com/journal_club/2015/12/30/a_new_potential_replacement_for_body_mass_index_109492.html|archive-date = 2016-01-01}}</ref><ref name="rahman2015">{{cite journal | vauthors = Rahman SA, Adjeroh D | title = Surface-Based Body Shape Index and Its Relationship with All-Cause Mortality | journal = PLOS ONE | volume = 10 | issue = 12 | pages = e0144639 | year = 2015 | pmid = 26709925 | pmc = 4692532 | doi = 10.1371/journal.pone.0144639 | bibcode = 2015PLoSO..1044639R | doi-access = free }}</ref>

A simplified, dimensionless form of SBSI, known as SBSI<sup>*</sup>, has also been developed.<ref name="rahman2015" />
