Little is known about the effects of gastric bypass surgery (GBS) on physical activity and physical function. We examined the physical activity, physical function, psychosocial correlates to physical activity participation, and health-related quality of life of patients before and after GBS.
A total of 20 patients were assessed before and 3 months after GBS. Physical activity was assessed using the 7-day physical activity recall questionnaire and a pedometer worn for 7 days. Physical function was assessed using the 6-minute walk test, Short Physical Performance Battery, and the physical function subscale of the Medical Outcomes Short Form-36 (SF-36). The Physical Activity Self-Efficacy questionnaire, the Physical Activity Barriers and Outcome Expectations questionnaire, the SF-36, and the Numeric Pain Rating Scale were also administered.
Physical activity did not significantly increase from before (191.1 +/- 228.23 min/wk) to after (231.7 +/- 230.04 min/wk) GBS (n = 18); however, the average daily steps did significantly increase (from 4621 +/- 3701 to 7370 +/- 4240 steps/d; n = 11). The scores for the 6-minute walk test (393 +/- 62.08 m to 446 +/- 41.39 m; n = 17), Short Physical Performance Battery (11.2 +/- 1.22 to 11.7 +/- .57; n = 18), physical function subscale of the SF-36 (65 +/- 18.5 to 84.1 +/- 19.9), and the total SF-36 (38.2 +/- 23.58 to 89.7 +/- 15.5; n = 17) increased significantly. The Numeric Pain Rating Scale score decreased significantly for low back (3.5 +/- 1.8 to 1.7 +/- 2.63), knee (2.4 +/- 2.51 to 1.0 +/- 1.43), and foot/ankle (2.3 +/- 2.8 to 0.9 +/- 2.05) pain. No significant changes were found in the Physical Activity Self-Efficacy questionnaire or the Physical Activity Barriers and Outcome Expectations questionnaire.
GBS improves physical function, health-related quality of life, and self-reported pain and results in a modest improvement in physical activity. These are important clinical benefits of surgical weight loss. Long-term follow-up is needed to quantify the ability to sustain or further improve these important clinical outcomes.
关于胃旁路手术（GBS）对体力活动和身体功能的影响知之甚少。我们研究了 GBS 前后患者的体力活动、身体功能、与体力活动参与相关的心理社会因素以及健康相关生活质量。
总共评估了 20 名患者在 GBS 前后的情况。使用 7 天体力活动回忆问卷和佩戴 7 天的计步器来评估体力活动。使用 6 分钟步行测试、简短身体表现电池和医疗结果简短形式 36（SF-36）的身体功能子量表来评估身体功能。还进行了体力活动自我效能问卷、体力活动障碍和结果期望问卷、SF-36 和数字疼痛评分量表。
从 GBS 前（191.1 +/- 228.23 分钟/周）到后（18 名患者中的 231.7 +/- 230.04 分钟/周），体力活动没有显著增加；然而，平均每日步数确实显著增加（从 4621 +/- 3701 到 7370 +/- 4240 步/天；n = 11）。6 分钟步行测试得分（393 +/- 62.08 米至 446 +/- 41.39 米；n = 17）、简短身体表现电池得分（11.2 +/- 1.22 至 11.7 +/-.57；n = 18）、SF-36 的身体功能子量表得分（65 +/- 18.5 至 84.1 +/- 19.9）和 SF-36 总分（38.2 +/- 23.58 至 89.7 +/- 15.5；n = 17）均显著增加。数字疼痛评分量表的下腰痛（3.5 +/- 1.8 至 1.7 +/- 2.63）、膝痛（2.4 +/- 2.51 至 1.0 +/- 1.43）和足部/踝关节疼痛（2.3 +/- 2.8 至 0.9 +/- 2.05）评分显著降低。体力活动自我效能问卷和体力活动障碍和结果期望问卷没有发现显著变化。
GBS 可改善身体功能、健康相关生活质量和自我报告的疼痛，并导致体力活动适度改善。这些是手术减肥的重要临床益处。需要进行长期随访以量化维持或进一步改善这些重要临床结果的能力。
