Background: There is a paucity of theory‐informed physical activity research with adults with intellectual disabilities. This study aimed to address this by synthesising existing literature and applying the COM‐B model to understand capabilities, opportunities and motivations. Methods: A qualitative evidence synthesis was conducted and reported in accordance with PRISMA guidelines and the ENTREQ. Three databases were systematically searched up to and including February 2022. Qualitative research relating to the physical activity of adults with intellectual disabilities were included. Thematic synthesis was conducted with themes mapped onto the COM‐B model. Results: Twenty‐five studies were included. Influences of physical activity were identified and mapped onto the COM‐B model, which also included COM‐B influences of social support provided by caregivers. Conclusions: There are many complex influences of physical activity for adults with intellectual disabilities. Researchers should consider the influences contributing to caregivers' capacity to support physical activity. [ABSTRACT FROM AUTHOR]

Introduction: Children and adolescents with intellectual disabilities participate in low levels of physical activity and have a greater reliance on their parents to provide activity opportunities. This study explored parents' experiences of promoting physical activity for their child with intellectual disabilities. Methods: Semi‐structured interviews were conducted with eight parents of children and adolescents with intellectual disabilities. Interviews were independently coded and analysed by two researchers using thematic analysis. Results: Four themes and nine subthemes were identified. Overall, parents had positive views of physical activity. However, parents face numerous barriers that limit their ability to promote physical activity for their child with intellectual disabilities. Conclusions: Parents experience high levels of exclusion and stigma that negatively affect their promotion of physical activity for their child with intellectual disabilities. Overcoming the barriers faced by parents could therefore be an indirect method to increase physical activity in children and adolescents with intellectual disabilities. [ABSTRACT FROM AUTHOR]

Background: The purpose of this study was to investigate the patterns of objectively measured sedentary behaviour in adults with intellectual disabilities. Methods: Baseline accelerometer data were pooled from two randomized controlled trials of lifestyle behaviour change programmes for adults with intellectual disabilities. Patterns of sedentary behaviours were computed including total volume, number, and duration of bouts and breaks. Results: Participants spent >70% of the day sedentary (8 hr), which was generally accumulated in short sedentary bouts (<10 min). Participants were engaged in significantly more sedentary time during the morning, although differences between time of day were small (mean bout duration range: 19.8–22.3 min). Conclusions: The findings add valuable insight into the patterns of sedentary behaviours among adults with intellectual disabilities. Further research investigating the patterns and context of sedentary behaviour is required to develop targeted interventions to reduce total sedentary time in adults with intellectual disabilities.

Background: Adults with intellectual disabilities are reported to be highly inactive, with research required to understand contributory factors. This systematic review aimed to investigate gender differences in physical activity (PA) and sedentary behaviour (SB) in adults with intellectual disabilities. Methods: This systematic review was reported in accordance with PRISMA guidelines. Seven databases were searched up to, and including, January 2018. Screening identified papers that assessed gender‐specific PA and/or SB outcomes in adults with intellectual disabilities. Data were synthesized using a narrative synthesis and random effects model meta‐analyses. Results: Twenty‐six papers were included; 25 measured PA, and eight assessed SB. Women with intellectual disabilities were least active with a significant overall effect of gender identified. For SB, no consistent gender differences were found. Conclusions: Reflecting the general population, men with intellectual disabilities were most active. Intellectual disability research should consider the role of gender to inform future interventions targeting inactivity. [ABSTRACT FROM AUTHOR]

Background: Valid objective measurement is integral to increasing our understanding of physical activity and sedentary behaviours. However, no population-specific cut points have been calibrated for children with intellectual disabilities. Therefore, this study aimed to calibrate and cross-validate the first population-specific accelerometer intensity cut points for children with intellectual disabilities. Methods: Fifty children with intellectual disabilities were randomly assigned to the calibration (n = 36; boys = 28, 9.53±1.08yrs) or cross-validation (n = 14; boys = 9, 9.57±1.16yrs) group. Participants completed a semi-structured school-based activity session, which included various activities ranging from sedentary to vigorous intensity. Direct observation (SOFIT tool) was used to calibrate the ActiGraph wGT3X+, which participants wore on the right hip. Receiver Operating Characteristic curve analyses determined the optimal cut points for sedentary, moderate, and vigorous intensity activity for the vertical axis and vector magnitude. Classification agreement was investigated using sensitivity, specificity, total agreement, and Cohen’s kappa scores against the criterion measure of SOFIT. Results: The optimal (AUC = .87−.94) vertical axis cut points (cpm) were ≤507 (sedentary), 1008−2300 (moderate), and ≥2301 (vigorous), which demonstrated high sensitivity (81−88%) and specificity (81−85%). The optimal (AUC = .86−.92) vector magnitude cut points (cpm) of ≤1863 (sedentary), 2610−4214 (moderate), and ≥4215 (vigorous) demonstrated comparable, albeit marginally lower, accuracy than the vertical axis cut points (sensitivity = 80−86%; specificity = 77−82%). Classification agreement ranged from moderate to almost perfect (κ = .51−.85) with high sensitivity and specificity, and confirmed the trend that accuracy increased with intensity, and vertical axis cut points provide higher classification agreement than vector magnitude cut points. Conclusions: This study provides the first valid methods of interpreting accelerometer output in children with intellectual disabilities. The calibrated physical activity cut points are notably higher than existing cut points, thus raising questions on the validity of previous low physical activity estimates in children with intellectual disabilities that were based on typically developing cut points.
