Effectiveness of a walking programme to support adults with intellectual disabilities to increase physical activity: walk well cluster-randomised controlled trial
Background Programs to change health behaviours have been identified as one way to reduce health inequalities experienced by disadvantaged groups . The objective of this study was to examine the effectiveness of a behaviour change programme to increase walking and reduce sedentary behaviour of adults with intellectual disabilities . Methods We used a cluster r and omised controlled design and recruited participants over 18 years old and not regularly involved in physical activity from intellectual disabilities community-based organisations . Assessment s were carried out blind to allocation . Clusters of participants were r and omly allocated to the Walk Well program or a 12-week waiting list control . Walk Well consisted of three face-to-face physical activity consultations incorporating behaviour change techniques , written re sources for participants and carers , and an individualised , structured walking programme . The primary outcome measured with accelerometers was change in mean step count per day between baseline and 12 weeks . Secondary outcomes included percentage time per day sedentary and in moderate-vigorous physical activity ( MVPA ) , body mass index ( BMI ) , and subjective well being . Results One hundred two participants in 50 clusters were r and omised . 82 ( 80.4 % ) participants completed the primary outcome . 66.7 % of participants lived in the most deprived quintile on the Scottish Index of Multiple Deprivation . At baseline , participants walked 4780 ( st and ard deviation 2432 ) steps per day , spent 65.5 % ( st and ard deviation 10.9 ) of time sedentary and 59 % percent had a body mass in the obesity range . After the walking programme , the difference between mean counts of the Walk Well and control group was 69.5 steps per day [ 95 % confidence interval ( CI ) -1054 to 1193.3 ] . There were no significant between group differences in percentage time sedentary 1.6 % ( 95 % CI −2.984 to 6.102 ) , percentage time in MVPA 0.3 % ( 95 % CI −0.7 to 1.3 ) , BMI −0.2 kg/m2 ( 95 % CI −0.8 to 0.4 ) or subjective well-being 0.3 ( 95 % CI −0.9 to 1.5 ) . Conclusions This is the first published trial of a walking program for adults with intellectual disabilities . Positively changing physical activity and sedentary behaviours may require more intensive programmes or upstream approaches to address the multiple social disadvantages experienced by adults with intellectual disabilities . Since participants spent the majority of their time sedentary , home-based programmes to reduce sitting time may be a viable health improvement approach .
