Research has shown that moderate-to-vigorous physical activity (MVPA) is associated with higher health-related quality of life (HRQOL) in healthy individuals. Recent studies have suggested that low- to moderate-intensity physical activity can be beneficial to HRQOL in people with inflammatory bowel diseases (IBD); however, studies investigating associations between MVPA and HRQOL in this population are lacking.
To understand the relationships among walking, MVPA, resilience, and HRQOL in people with IBD.
People with IBD (n = 242) completed questions about physical activity, resilience and HRQOL. Pearson product-moment correlations and multiple regression analyses were used to identify associations between physical activity and HRQOL. Analysis of covariance was used to compare HRQOL over quartiles of walking and MVPA with demographic variables as covariates.
Both walking and MVPA were independently associated with physical (β = 0.21 and β = 0.26, respectively; p ≤ 0.001) but not mental HRQOL (p > 0.05). Higher volumes of MVPA were significantly associated with physical HRQOL (quartile 1 40.3 ± 9.0 vs. quartile 4 47.4 ± 9.0; p < 0.001) while higher volumes of walking were associated with both physical and mental HRQOL (p ≤ 0.01).
The findings suggest that engaging in higher volumes of MVPA above 150 min/week and walking, particularly above 60 min/week, are associated with improved HRQOL in people with IBD. Research would benefit from investigating participation in MVPA as a coping strategy, in a longitudinal manner, to determine which modes of activity may be most beneficial to people with IBD.
了解炎症性肠病(IBD)患者的步行、中高强度体力活动(MVPA)、韧性与健康相关生活质量(HRQOL)之间的关系。
IBD 患者(n=242)完成了关于体力活动、韧性和 HRQOL 的问题。使用 Pearson 积矩相关和多元回归分析来确定体力活动与 HRQOL 之间的关系。协方差分析用于比较步行和 MVPA 四分位数与人口统计学变量作为协变量的 HRQOL。
步行和 MVPA 均与生理 HRQOL 独立相关(β=0.21 和 β=0.26,分别;p≤0.001),但与心理 HRQOL 无关(p>0.05)。更高的 MVPA 量与生理 HRQOL 显著相关(四分位数 1 为 40.3±9.0,四分位数 4 为 47.4±9.0;p<0.001),而更高的步行量与生理和心理 HRQOL 均相关(p≤0.01)。
研究结果表明,每周进行 150 分钟以上的 MVPA 和步行,特别是每周 60 分钟以上的 MVPA 和步行,与 IBD 患者的 HRQOL 改善有关。研究需要通过纵向方式研究 MVPA 的参与作为一种应对策略,以确定哪种活动模式对 IBD 患者最有益。
