Se basa en encuestas realizadas a 3.133 personas que manifestaron experimentar síntomas de enfermedad por reflujo gastroesofágico (ERGE) y a 39.872 sin tales síntomas.
Los resultados muestran que la obesidad incrementa el riesgo de la ERGE (aquellos con índice de masa corporal superior a 35 tienen seis veces más probabilidades que aquellos con un índice inferior a 25), y que la relación es más estrecha en el caso de las mujeres.
Además, se ha observado que el estrógeno puede desempeñar un papel en el riesgo de ERGE, dado que la relación entre la obesidad y esta enfermedad es más potente entre mujeres premenopáusicas.
