  1. Note a Data on physical activity and intention were reported in Kinmonth et al. [20]. b Means include participants with baseline missing data. c Difference in means at 6 and 12 months respectively between combined intervention groups and advice group, adjusted for baseline measure, age, living with children, behavioural intention, BMI and objective physical activity level (PAL) balanced across trial arms for gender. n = number of participants on which analysis is based. d Participants with a value at least four standard deviations from the mean were excluded. e Only participants who reported having children and a partner at the relevant time-points were included in the analysis.
