To estimate health care and health-related productivity costs associated with excessive sedentary behaviour (> 8 h/day and > 9 h/day) in Canadian adults.
Three pieces of information were used to estimate costs: (1) the pooled relative risk estimates of adverse health outcomes consistently shown to be associated with excessive sedentary behaviour, gathered from meta-analyses of prospective cohort studies; (2) the prevalence of excessive sedentary behaviour in Canadian men and women, obtained using waist-worn accelerometry in a nationally representative sample of adults (Canadian Health Measures Survey 2018-2019); and (3) the direct (health care) and indirect (lost productivity due to premature mortality) costs of the adverse health outcomes, selected using the Economic Burden of Illness in Canada 2010 data. The 2010 costs were then adjusted to 2021 costs to account for inflation, population growth, and higher average earnings. A Monte Carlo simulation was conducted to account for uncertainty in the model.
The total costs of excessive sedentary behaviour in Canada were $2.2 billion (8 h/day cut-point) and $1.8 billion (9 h/day cut-point) in 2021, representing 1.6% and 1.3% of the overall burden of illness costs, respectively. The two most expensive chronic diseases attributable to excessive sedentary behaviour were cardiovascular disease and type 2 diabetes. A 10% decrease in excessive sedentary behaviour (from 87.7% to 77.7%) would save an estimated $219 million per year in costs.
Excessive sedentary behaviour significantly contributes to the economic burden of illness in Canada. There is a need for evidence-based and cost-effective strategies that reduce excessive sedentary behaviour in the population.
估计与加拿大成年人过度久坐行为（> 8 小时/天和> 9 小时/天）相关的医疗保健和健康相关生产力成本。
使用以下三种信息来估计成本：（1）荟萃分析前瞻性队列研究一致表明与过度久坐行为相关的不良健康结果的汇总相对风险估计值；（2）使用腰部佩戴的加速度计在加拿大成年人的全国代表性样本中获得的加拿大男性和女性过度久坐行为的流行率（2018-2019 年加拿大健康测量调查）；（3）使用 2010 年加拿大疾病经济负担数据选择的不良健康结果的直接（医疗保健）和间接（因过早死亡导致的生产力损失）成本。然后，根据通货膨胀、人口增长和更高的平均收入，将 2010 年的成本调整为 2021 年的成本。进行蒙特卡罗模拟以考虑模型中的不确定性。
2021 年，加拿大过度久坐行为的总成本为 22 亿美元（8 小时/天切点）和 18 亿美元（9 小时/天切点），分别占总疾病负担成本的 1.6%和 1.3%。归因于过度久坐行为的两种最昂贵的慢性病是心血管疾病和 2 型糖尿病。如果将过度久坐行为减少 10%（从 87.7%降至 77.7%），预计每年可节省约 2.19 亿美元的成本。
过度久坐行为对加拿大的疾病经济负担有重大贡献。需要采取基于证据和具有成本效益的策略来减少人群中的过度久坐行为。
