Elementary school children’s recess schedule and dietary intake at lunch: a community-based participatory research partnership pilot study

Table 1 Association of recess order with probability of consumption meeting nutritional guidelines

Nutrient	Probability modeled	Mean probability before lunch	After lunch	OR (95% CI)	p-value (two sided)

	(75% guideline)	27%	23%	1.27 (0.9 – 1.8)	0.169
Protein	Intake > =9 g	86%	84%	1.22 (0.9 – 1.7)	0.270
Iron	Intake > =3.3 mg	15%	13%	1.20 (0.8 – 1.7)	0.304
Calcium	Intake > =267 mg	68%	59%	1.49 (1.1 – 2.0)	0.015*

Sodium⁴ Day 5	Sodium < =1200 mg	100%	99%

¹Too few students met 100% of guideline to model this probability, so a lower cut-off was used.
²Excludes Day 3 because no students met guideline for Vitamin C on Day 3 (maximum intake = 2.96 mg).
³Too few students met guideline of 10% to model this probability, so a higher cut-off was used.
⁴Too variable by day to combine days into a single model.
*p < 0.05.
OR = odds ratio.
