Secondary trial outcomes: awareness, knowledge and implementation of the Guidelines
There were no statistically significant differences in awareness and knowledge of the Guidelines between either intervention group and control services (see Table 
Secondary outcomes: Awareness, knowledge and implementation of the Guidelines1.37(0.34, 5.51);p = 0.666.19(0.66, 58.16);p = 0.114.52(0.48, 42.70);p = 0.191.45(0.60, 3.52);p = 0.401.03(0.43, 2.48);p = 0.940.71(0.30, 1.67);p = 0.431.68(0.29, 9.66);p = 0.552.12(0.44, 10.25);p = 0.351.26(0.27, 5.78);p = 0.76Whilst not statistically significant, more services that received the animated video implemented the Guidelines (i.e. i) offered an indoor-outdoor program for the full day; or ii) offered more time outdoors (26%, compared to 19% for the e-newsletter group and 14% for the control group) (see Table 
There were no statistically significant differences between groups in the reporting of common barriers to adoption of indoor-outdoor programs and offering more time outdoors. However, for the control group, for two of the domains measured; ‘Beliefs about capabilities’ and ‘Social influences’, the mean score was below 5, indicating they are a barrier to Guideline implementation (see Table 
Barriers to guideline implementation0.03(-0.44, 0.50);p = 0.90-0.10(-0.58, 0.38);p = 0.69-0.13(-0.58, 0.33);p = 0.580.35(-0.23, 0.93);p = 0.230.17(-0.43, 0.76);p = 0.58-0.18(-0.74, 0.37);p = 0.510.31(-0.25, 0.87);p = 0.270.20(-0.38, 0.78);p = 0.49-0.11(-0.65, 0.43);p = 0.68Based largely on research team salary and time, the development costs of the intervention arms were as follows; control email AUD$58.88, e-newsletter AUD$1,387.60 and animated video AUD$3,787.82. The higher cost to develop the animated video is due to staff time and the initial software purchase cost. The cost to deliver the emails was AUD$294.40 split across the three groups.As can be seen in Table 
Reach and fidelity of the dissemination strategiesUnique views for e-newsletter, counts as views from unique device. Unique views for animated video counts as views for 30 s or more. Average time viewers spent watching/viewing strategies. Average completion for e-newsletter, is how far all viewers scrolled through the e-newsletter. Average completion of the animated video, is the percent of each video the average viewer watched. In-depth read of e-newsletter, counted as the viewers that spent a significant time reading through and interacting with the content
