Adults with intellectual disabilities experience numerous health inequalities. Targeting unhealthy lifestyle behaviours, such as high levels of sedentary behaviour and overweight/obesity, is a priority area for improving the health and adults with intellectual disabilities and reducing inequalities. Energy expenditure is a fundamental component of numerous health behaviours and an essential component of various free-living behaviour measurements, e.g. accelerometry. However, little is known about energy expenditure in adults with intellectual disabilities and no population-specific accelerometer data interpretation methods have been calibrated. The limited research in this area suggests that adults with intellectual disabilities have a higher energy expenditure, which requires further exploration, and could have significant impacts of device calibration. However, due to the complex methods required for measuring energy expenditure, it is essential to first evaluate feasibility and develop an effective protocol. This study aims to test the feasibility of a laboratory-based protocol to enable the measurement of energy expenditure and accelerometer calibration in adults with intellectual disabilities.We aimed to recruit ten adults (≥ 18 years) with intellectual disabilities. The protocol involved a total of nine sedentary, stationary, and physical activities, e.g. sitting, lying down, standing, and treadmill walking. Each activity was for 5 min, with one 10 min lying down activity to measure resting energy expenditure. Breath by breath respiratory gas exchange and accelerometry (ActiGraph and ActivPAL) were measured during each activity. Feasibility was assessed descriptively using recruitment and outcome measurement completion rates, and participant/stakeholder feedback.Ten adults (N = 7 female) with intellectual disabilities participated in this study. The recruitment rate was 50% and 90% completed the protocol and all outcome measures. Therefore, the recruitment strategy and protocol are feasible.This study addresses a significant gap in our knowledge relating to exercise laboratory-based research for adults with intellectual disabilities The findings from this study provide essential data that can be used to inform the development of future protocols to measure energy expenditure and for accelerometer calibration in adults with intellectual disabilities.
成年智障人士面临诸多健康不平等问题。针对不健康的生活方式行为，如久坐行为水平高和超重/肥胖，是改善成年智障人士健康状况及减少不平等现象的一个优先领域。能量消耗是众多健康行为的基本组成部分，也是各种自由生活行为测量（如加速度计测量）的重要组成部分。然而，对于成年智障人士的能量消耗情况知之甚少，且尚未校准针对特定人群的加速度计数据解读方法。该领域的有限研究表明，成年智障人士的能量消耗较高，这需要进一步探索，且可能对设备校准产生重大影响。然而，由于测量能量消耗所需方法复杂，首先评估可行性并制定有效的方案至关重要。本研究旨在测试一种基于实验室的方案在成年智障人士中测量能量消耗及进行加速度计校准的可行性。我们的目标是招募10名年龄≥18岁的成年智障人士。该方案总共包括9种久坐、静止和体力活动，如坐着、躺下、站立和跑步机行走。每种活动持续5分钟，其中有一项10分钟的躺下活动用于测量静息能量消耗。在每项活动期间测量逐次呼吸的呼吸气体交换和加速度（ActiGraph和ActivPAL）。通过招募率和结果测量完成率以及参与者/利益相关者的反馈来描述性地评估可行性。10名成年智障人士（N = 7名女性）参与了本研究。招募率为50%，90%的人完成了方案及所有结果测量。因此，招募策略和方案是可行的。本研究填补了我们在成年智障人士基于运动实验室研究方面知识的重大空白。本研究的结果提供了重要数据，可用于为未来测量成年智障人士能量消耗及进行加速度计校准的方案制定提供参考。
