The purpose of this study was to determine whether postmeal walking (PMW, breaking up exercise into short bouts after meals) is an effective and feasible alternative to continuous walking for the management of gestational diabetes. Forty-one women with gestational diabetes were randomised between weeks 28-30 gestation to either standard care (30 minutes continuous exercise) or standard care with PMW (10 minutes of walking after breakfast, lunch, and dinner). Continuous glucose and activity monitors were worn to measure glycaemic control and adherence during 3 days of standard care (baseline) followed by 3 days of postmeal or continuous walking. A linear mixed model analysed the changes from baseline between postmeal and continuous walking, as an average of the 3-day periods. Thirty-two women (PMW = 17: control = 15, 33 ± 5 years, body mass index 25 ± 4 kg·m) completed the trial. Postprandial and overnight glucose concentrations were similar between PMW and control; both interventions improved from baseline. There was no difference in adherence between groups; however, PMW completed more minutes of prescribed physical activity across baseline and intervention days compared to the continuous walking standard-care group. Preliminary findings from this proof-of-concept study suggest PMW could be a promising alternative to, and work interchangeably with, traditional advice to perform continuous moderate-intensity physical activity in women with gestational diabetes. Three 10-minute postmeal walks may be comparable to 30 minutes continuous walking for glucose control in women with gestational diabetes. Accumulating activity in short bouts after meals is a feasible alternate to continuous exercise for women with gestational diabetes.
这项研究的目的是确定餐后散步（PMW，即在用餐结束后将运动分成短时间的小段）是否是一种替代连续散步的有效且可行的方法，用于管理妊娠糖尿病。将 41 名妊娠糖尿病女性随机分为 28-30 孕周的标准护理组（30 分钟连续运动）或标准护理加 PMW 组（早餐、午餐和晚餐后各进行 10 分钟散步）。连续葡萄糖和活动监测器用于测量标准护理 3 天（基线）期间的血糖控制和依从性，然后是餐后或连续散步 3 天。线性混合模型分析了从基线到餐后和连续散步之间的变化，作为 3 天期间的平均值。32 名女性（PMW = 17：对照组 = 15，33 ± 5 岁，体重指数 25 ± 4kg·m）完成了试验。PMW 和对照组的餐后和夜间血糖浓度相似；两种干预措施均较基线有所改善。两组之间的依从性没有差异；然而，PMW 在基线和干预日期间完成的规定体力活动分钟数比连续散步标准护理组多。这项概念验证研究的初步结果表明，PMW 可能是一种有前途的替代方法，可以与传统建议交替使用，即让妊娠糖尿病女性进行连续的中等强度体力活动。三次 10 分钟的餐后散步可能与妊娠糖尿病女性的 30 分钟连续散步一样，可控制血糖。在用餐结束后进行短时间的活动是妊娠糖尿病女性替代连续运动的可行方法。
