HealthDay News–Adherence to 5 lifestyle factors is associated with a decreased risk for gastroesophageal reflux disease (GERD) symptoms, according to a research letter published in JAMA Internal Medicine.
Raaj S. Mehta, M.D., from Massachusetts General Hospital and Harvard Medical School in Boston, and colleagues used data from the Nurses’ Health Study II to evaluate associations between dietary and lifestyle factors with the risk for GERD symptoms. An antireflux lifestyle score (range, 0 to 5) was calculated based on 5 variables: normal weight; never smoking; moderate-to-vigorous physical activity for at least 30 minutes daily; no more than 2 cups of coffee, tea, or soda daily; and a prudent diet (top 40% of the dietary pattern score).
Among 42,955 women aged 42 to 62 years, the researchers identified 9291 incident cases of GERD symptoms. For women with the 5 antireflux lifestyle factors, the risk for GERD symptoms was reduced (hazard ratio, 0.50). The investigators estimated that 37% of cases of GERD symptoms may be prevented by adopting all 5 lifestyle factors. There were independent associations seen between each of the 5 lifestyle factors and GERD symptoms. The mutually adjusted multivariable hazard ratios for nonadherence to each lifestyle factor ranged from 0.94 for smoking to 0.69 for body mass index.
“These data support the importance of lifestyle modification in management of GERD symptoms,” the authors write.
