b. Intervention effects on changes in anthropometric measures from birth to 24 months
	tribe A N pairs=53	tribe B N pairs=56	tribe C N pairs=68	Total B+C N pairs=124
BMI for age Z-score
Change from 0–24 mos—Study populations	2.92 (1.82)	1.86 (1.72)	2.44 (1.84)	2.18 (1.80)
Change from 0–24 mos—PedNSS (comparison)	2.03 (2.22)	1.74 (1.46)	2.23 (1.52)	2.01 (1.50)
Intervention Effecta		-0.81, p=0.025	-0.70, p=.036	-0.75, p=.016
Weight for age Z-score
Change from 0–24 mos—Study populations	1.57 (1.64)	0.52 (1.35)	1.20 (1.50)	0.89 (1.46)
Change from 0–24 mos—PedNSS (comparison)	1.22 (1.75)	0.41 (1.23)	1.01 (1.19)	0.75 (1.24)
Intervention Effect		-0.29, p=.167	-0.20, p=.242	-0.24, p=.173
Height for age Z-score
Change from 0–24 mos—Study populations	−0.90 (1.81)	−1.59 (1.67)	−0.97 (1.52)	−1.25 (1.61)
Change from 0–24 mos—PedNSS (comparison)	−0.43 (2.37)	−1.62 (1.42)	−1.01 (1.42)	−1.27 (1.45)
Intervention Effect		0.28, p=.798	0.17, p= .700	0.23, p=.781

All p-values are one-sided, to detect a decrease in BMI in tribes receiving the community+family intervention relative to the tribe receiving only the community intervention.
