The association between objectively measured bouted (at least 10 min in duration) and non-bouted (<10 min in duration) physical activity with multimorbidity is unknown, which was the purpose of this study.
Data from the 2003-2006 National Health and Nutrition Examination Survey (NHANES) were employed (n = 4 584 adults). Bouted physical activity and non-bouted physical activity were assessed via accelerometry, with multimorbidity assessed via physician diagnosis and laboratory data.
For the ordinal regression model, and after adjustment, both non-bouted moderate-to-vigorous physical activity (MVPA; β = -0·63; 95% CI: -0·79 to -0·48; P<0·001) and bouted MVPA (β = -0·43; 95% CI: -0·63 to -0·23; P<0·001) were independently associated with multimorbidity. In a multivariable logistic regression, both non-bouted MVPA (OR = 0·59; 95% CI: 0·48-0·72; P<0·001) and bouted MVPA (OR = 0·66; 95% CI: 0·52-0·84; P = 0·001) were associated with a reduced odds of being multimorbid.
Both bouted MVPA and non-bouted MVPA were associated with reduced odds of multimorbidity, underscoring the importance of promoting both types of physical activity.
客观测量的持续时间至少10分钟的连续性体力活动和持续时间不足10分钟的非连续性体力活动与多种疾病并存之间的关联尚不清楚，本研究旨在探究这一问题。
采用2003 - 2006年美国国家健康与营养检查调查（NHANES）的数据（n = 4584名成年人）。通过加速度计评估连续性体力活动和非连续性体力活动，通过医生诊断和实验室数据评估多种疾病并存情况。
对于有序回归模型，调整后，非连续性中等至剧烈体力活动（MVPA；β = -0.63；95%CI：-0.79至-0.48；P<0.001）和连续性MVPA（β = -0.43；95%CI：-0.63至-0.23；P<0.001）均与多种疾病并存独立相关。在多变量逻辑回归中，非连续性MVPA（OR = 0.59；95%CI：0.48 - 0.72；P<0.001）和连续性MVPA（OR = 0.66；95%CI：0.52 - 0.84；P = 0.001）均与多种疾病并存几率降低相关。
连续性MVPA和非连续性MVPA均与多种疾病并存几率降低相关，强调了促进这两种体力活动类型的重要性。
