New Zealand Diet Quality Index for Adolescents (NZDQI-A), saturated fat (SFA), monounsaturated fat (MUFA), polyunsaturated fat (PUFA), not significant (NS).

1 All nutrients except for calcium, iron and vitamin C were adjusted for total energy intake using the residual method [45]. Values are presented as means or geometric means if log-transformed.

2 P value for trend across the thirds using the non-parametric trend analysis.
