Importance And Objective:
Gastroesophageal reflux disease (GERD) is a chronic condition associated with several risk factors, but little is known about the association between hormone therapy (HT) and GERD in postmenopausal women.
Evidence Review:
We investigated the association between ever or current menopausal HT use and GERD using a systematic review and meta-analysis. Studies published between 2008 and August 31, 2022, were pooled using a DerSimonian and Laird random-effects model, and outcomes were reported as adjusted odds ratios (aOR) with a corresponding 95% CI.
Findings:
The pooled analysis of five studies found a significant direct association between estrogen use and GERD (aOR, 1.41; 95% CI, 1.16-1.66; I2 = 97.6%), and progestogen use and GERD (two studies: aOR, 1.39; 95% CI, 1.15-1.64; I2 = 0.0%). The use of combined HT was also associated with GERD (1.16; 95% CI, 1.00-1.33; I2 = 87.9%). Overall, HT use was associated with 29% higher odds for GERD (aOR, 1.29; 95% CI, 1.17-1.42; I2 = 94.8%). The large number of pooled participants, differences in study design, geography, patient characteristics, and outcome assessment resulted in significant high heterogeneity.
Conclusions And Relevance:
There is a significant association between ever or current HT use and GERD. However, the results should be interpreted with caution, given the small number of included studies and high heterogeneity. This warrants careful evaluation of GERD risk factors when prescribing HT to reduce the risk of potential GERD complications.
