Risk Factor-Related Lifestyle Habits of Patients With Laryngopharyngeal Reflux.

Objective: The role of lifestyle habits in patients with laryngopharyngeal reflux disease (LPRD) is comparatively underexplored. We aim to examine the specific lifestyle habits in patients with LPRD.

Methods: Systematic sampling was applied to select respondents aged 18 through 80 years in otorhinolaryngology-head and neck surgery (OHNS) clinics in Nan Fang Hospital during August 2017-July 2018, 1658 eligible participants were included by a systematic sampling method. Subjects with RSI score>13 were considered as LPRD patients. The risk of reflux symptoms was estimated and multivariate calculated as odds ratios in relation to exposure to tobacco smoking, alcohol, coffee, tea, carbonated drinks, chocolate, spicy food, night sleep time, dinner-to-bed time, subjective sleep quality, and physical exercise.

Results: There was a significant dose-response association between carbonated beverage and LPRD. Among people who had drinking carbonated drinks the odds ratio was 1.76 (OR 1.77, 95% CI 1.24-2.50, P = .002) compared with non-carbonated drinker. A similar positive association was found for poor subjective sleep quality and shorter night sleeping time, the odds ratio for reflux was 1.58 (95% CI 1.14 to 2.18) among those who always have poor subjective sleep quality compared with those whose have good subjective sleep quality. The odds ratio for reflux was 2.29 (95% CI 1.23-4.28, P = .015) among those who always sleep 3-5 hours every night compared with those who sleep more than 8 hours every night. Beyond that, we found high BMI may have a negative correlation with LPRD, the odds ratio for reflux was .61 (95% CI 0.39 to .95, P = .054) among those whose BMI >25 kg/m2 compared with those BMI ≤ 20 kg/m2.

Conclusions: Patients with LPRD may have certain lifestyle habits, avoid carbonated beverage, poor subjective sleep quality, and lack of sleep should be advised in treatment of LPRD.
