*Due to summer holidays at schools, at least one questionnaire was skipped in each kitchen series. Five series finished the intervention at 9 months (I9, nā=ā157) and 11 series at 12 months (I12). The post-intervention assessment (PIA) was thus made either at 9 or 12 months after the start of the implementation phase of the intervention (combined nā=ā452).
