Table 1. Indicators of obesity among all age-groups according to the share of processed and ultra-processed food products in total household food availability (Brazil, 2008–2009).

	Obesity indicator
	Mean BMI (Z score)	Prevalence of excess weight (%)¹	Prevalence of obesity (%)¹
Quartiles of the contribution of processed and ultra-processed products (% of total dietary energy)	Mean (SE)	Mean (SE)	Mean (SE)
1^st (1. 6%–21.8%)	0.53 (0.02)	34.1 (0.6)	9.8 (0.3)
2^nd (21.8%–28.3%)	0.68 (0.02)	39.6 (0.6)	12.3 (0.3)
3^rd (28.5%–34.8%)	0.81 (0.02)	43.8 (0.6)	14.1 (0.4)
4^th (34.8%–54.9%)	0.81 (0.02)^*	43.9 (0.6)^*	13.1 (0.5)^*

Classification follows recommendations of the World Health Organization for each age group [26], [27], [28].
