Background:
Functional dyspepsia (FD) has a high prevalence worldwide and reduces patients' quality of life. The etiology of FD is likely multifactorial. Although two studies showed an inverse association between exercise habits and FD, evidence regarding the association between exercise habits and FD remains scarce.
Aims:
This study aimed to investigate the association between exercise habits and FD among the young Japanese population, taking the presence or absence of an exercise partner as an additional variable.
Methods:
The study subjects consisted of 8923 Japanese university students. The definition of FD was based on the Rome III criteria. Information on exercise frequency, exercise intensity, and exercise partners was obtained from a self-administered questionnaire.
Results:
The prevalence of FD was 1.9% in this cohort. Low, moderate, and high frequency of exercise was independently inversely associated with FD (adjusted odds ratio [OR] was low: OR 0.69 [95% confidence interval (CI) 0.47-0.997], moderate: OR 0.53 [95% CI 0.34-0.81] and high: OR 0.53 [95% CI 0.30-0.88], p for trend p = 0.002). Moderate and high intensity of exercise was independently inversely associated with FD (moderate: OR 0.56 [95% CI 0.36-0.84] and high: OR 0.49 [95% CI 0.30-0.76], p for trend p = 0.001). Exercise with groups and with friends was independently inversely associated with FD whereas the association between exercising alone and FD was not significant (groups: OR 0.28 [95% CI 0.14-0.50] and friends: OR 0.44 [95% CI 0.24-0.74]).
Conclusion:
Among the young Japanese population, frequency and intensity of exercise may be independently inversely associated with FD. Additionally, exercise with groups and with friends but not by oneself was inversely associated with exercise and FD, respectively.

Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
