A short meal-to-bed time drastically increases GERD risk in pregnant women: Study

Short meal-to-bed time (MTBT) has been reported to relate to gastroesophageal reflux disease (GERD), but evidence is lacking in pregnant women. Researchers aimed to assess the characteristics of GERD and the association between MTBT and GERD during pregnancy.

For the study design,A cross-sectional study was carried out on 400 pregnant women aged 18 years and older visiting the antenatal clinic of Gia-Dinh People's Hospital, Vietnam. GERD was defined as having troublesome heartburn and/or regurgitation at least once a week. Reflux-related insomnia was defined as having difficulties in initiating or maintaining sleep through the night. MTBT was defined as "short" if it was ≤2 hours in more than two thirds of days in a week.

Results revealed some key facts.

• There were 154 (38.5%) patients with GERD and 20 (13.0%) patients with reflux-related insomnia. In multivariate analysis, there were 3 factors significantly associated with GERD: third trimester [odds ratio (OR)=1.66; 95% confidence interval (CI): 1.03-2.69], previous history of typical reflux symptoms (OR=9.05; 95% CI: 5.29-15.50), and short MTBT (OR=12.73; 95% CI: 2.92-55.45).
• The frequency of reflux symptoms progressively increased across subgroups of patients with no short MTBT, either daytime or nighttime short MTBT, and with both daytime and nighttime short MTBT.
• Nighttime MTBT was also a significant risk factor for reflux-related insomnia (OR=4.60; 95% CI: 1.64-12.92).

"We reported for the first time that short MTBT was a predominant risk factor of GERD in pregnancy. This dieting habit was significantly associated with reflux symptom frequency and reflux-related insomnia."the team concluded.
