Stochastic dominance tests of the BMI distribution, 1971-2014

Survey years	Dominance tests
(1971-1974) - (1976-1980)	1
(1976-1980) - (1988-1991)	1
(1988-1991) - (1991-1994)	1
(1991-1994) - (1999-2002)	1
(1999-2002) - (2003-2006)	1
(2003-2006) - (2007-2010)	ND
(2007-2010) - (2011-2014)	−1
(1971-1974) - (1988-1991)	1
(1988-1991) - (1999-2002)	1
(1999-2002) - (2011-2014)	1

Note: 1 and ND represent first-order stochastic dominance and no dominance, respectively; -1 denotes that the 2007-2010 distribution dominates the 2011-2014. (No second or third order stochastic dominance were detected.) Data Source: NHANES
