UNASSIGNED: Constipation was defined based on stool consistency and frequency, while overall diet quality was assessed using Healthy Eating Index (HEI)-2015 scores. Participants were categorized into low (metabolic equivalent [MET]-min/wk < 500) and high physical activity groups (MET-min/wk ≥ 500). The association between diet and constipation across physical activity groups was analyzed using survey logistic regression and restricted cubic splines.
UNASSIGNED: Higher HEI-2015 scores were associated with reduced constipation risk in the high physical activity group when constipation was defined by stool consistency (odds ratio [OR], 0.98; 95% confidence interval [CI], 0.97-0.99). However, in the low physical activity group, increased HEI-2015 scores did not significantly affect constipation risk (OR, 1.01; 95% CI, 0.97-1.05). Similar results were found when constipation was defined based on stool frequency. In the high physical activity group, increased HEI-2015 scores were significantly associated with a reduced constipation risk (OR, 0.96; 95% CI, 0.94-0.98). Conversely, in the low physical activity group, increased HEI-2015 scores did not affect the risk of constipation (OR, 0.96; 95% CI, 0.90-1.03).
UNASSIGNED: Our findings suggest that a higher HEI-2015 score is negatively associated with constipation among individuals with high physical activity levels but not among those with low physical activity levels. This association was consistent when different definitions of constipation were used. These results highlight the importance of combining healthy diet with regular physical activity to alleviate constipation.
■便秘是根据粪便稠度和频率定义的,而总体饮食质量使用健康饮食指数(HEI)-2015评分进行评估。参与者分为低(代谢当量[MET]-min/wk<500)和高体力活动组(MET-min/wk≥500)。使用调查逻辑回归和有限的三次样条分析了不同体力活动组的饮食和便秘之间的关联。
■当便秘由大便稠度定义时,较高的HEI-2015评分与高体力活动组便秘风险降低相关(比值比[OR],0.98;95%置信区间[CI],0.97-0.99)。然而,在低体力活动组,增加的HEI-2015评分没有显著影响便秘风险(OR,1.01;95%CI,0.97-1.05)。当根据粪便频率定义便秘时,发现了类似的结果。在高体力活动组中,HEI-2015评分的增加与便秘风险的降低显着相关(OR,0.96;95%CI,0.94-0.98)。相反,在低体力活动组,增加的HEI-2015评分并不影响便秘的风险(OR,0.96;95%CI,0.90-1.03)。
■我们的研究结果表明,较高的HEI-2015评分与高体力活动水平的个体便秘呈负相关,而与低体力活动水平的个体无关。当使用不同的便秘定义时,这种关联是一致的。这些结果强调了将健康饮食与定期体育锻炼相结合以缓解便秘的重要性。
