Consuming school meals improves Brazilian children's diets according to their social vulnerability risk.

Abstract

To estimate usual diets among Brazilian children regarding the consumption of school meals and social vulnerability risks. A cross-sectional study. School meal consumers were considered those children who reported consuming school meals ≥3 times/week. Social vulnerability risk was classified by an index. Dietary intake was evaluated by one 24 h dietary recall for the whole sample; a second 24 h dietary recall was administered in a sub-sample (38·6 %). The National Cancer Institute's method was used to estimate children's usual intake of nutrients and food groups. Municipal public schools from Belo Horizonte, Brazil. Children (n 1357) aged 8-12 years. Half of the sample lived in low/medium social vulnerability risk areas and 27·9 % were school meal non-consumers. School meal consumers more frequently lived in high/very high social vulnerability risk areas (76·2 v. 68·7 %). Children with low/medium social vulnerability risk had a higher mean intake of thiamin (1·13 v. 1·04 mg) and a lower mean intake of candy (1·35 v. 1·42 g). Consumption of school meals among children under high/very high social vulnerability risk was associated with higher mean consumption of vitamin C (31·9 v. 24·1 mg), unprocessed/minimally processed foods (956·3 v. 851·9 g), fruits (128·5 v. 90·9 g) and vegetables (58·2 v. 47·1 g). Ultra-processed food product consumption was lower among school meal consumers (136·2 v. 187·7 g), especially ultra-processed beverages (252·5 v. 305·7 g). Consuming school meals was associated with a better usual diet quality, particularly among those with higher social vulnerability risk.
