Parents lower in authoritarian parenting level reported higher PA at time 2, compared to time 1. Aside from the lack of main intervention effects, there were significant interactions between socio-economic status and parent FV consumption (F1, 47 = 5.51, p = .023). Parents of lower socio-economic status in the control condition reported significant increases of FV consumption across times 1 and 2. There was a signifi- cant interaction between girl weight status and parent eating with TV (F1, 50 = 6.95, p = .011). Parents of over- weight girls in the control condition increased eating with TV across the two time periods. Finally, there was a significant interaction between attendance level and intervention on parent PA (F1, 50 = 5.07, p = .029). The parents of girls with irregular attendance increased sig- nificantly in PA across the two time points. Discussion The results of this study confirmed that troops ran- domly assigned to the intervention condition provided more leader promotion and opportunities for PA and healthful eating than control condition troops. Evidence of preferential effects from the intervention on obesity and its behavioral influences was limited solely to objec- tively measured PA levels of girls while attending troop Table 5 Troop environment and troop leader behavior by condition Meeting time was structured (%) PA knowledge content (%) HE knowledge content (%) Family connection content (%) Any PA promotion (%) Any HE promotion (%) No PA or HE promotion (%) Any PA discouragement (%)a Any HE discouragement (%)a No PA or HE discouragement (%)a Intervention Troops 97.4 6.0 11.7 3.1 16.6 18.9 64.5 0.2 0 99.8 Control Troops 90.3 0.3 0.4 0.0 1.5 0.4 99.1 0.6 0.3 99.1 X2 5.44 6.38 13.64 3.09 23.46 18.14 1167.7 4.64 5.88 9.63 Significance P = .020 P = .012 P < .001 P = .079 P < .001 P < .001 P < .001 P = .031 P = .015 P = .002 Note: PA = Physical activity; HE = healthful eating; aThis X2 calculated based on actual observed number, rather than percent
