OBJECTIVETo analyze functional dyspepsia prevalence and associated factors of naval forces.

METHODBy stratified random cluster sampling method, conducted a questionnaire survey and diagnosis of functional dyspepsia to 11 520 military sea forces, and analyzed risk in clinical factors. Large sample size of 3084 cases in the diagnosis of functional dyspepsia, analyzed correlation of the selected 100 patients by single sample random sampling method.

RESULTNaval forces, functional dyspepsia prevalence was 29.27% (3084/10537), and logistic regression analysis showed that job factors of military service, military rank, the nature of the work, the training intensity, training environmental P = 0.028, 0.023, 0.000, 0.000, 0.014, OR = 10.308, 6.288, 22.504, 26.720, 9.825; life factors of daily water intake, eating fruits and frequency of sleep time, spicy eating habits, drinking history factors P = 0.000, 0.012, 0.025, 0.017, 0.027, OR = 28.467, 20.335, 11.358, 10.249, 9.578; psychological factors, depression, anxiety factor P = 0.024, 0.019, OR = 16.878, 18.025;generally age, gender, ethnicity, BMI index, gastrointestinal history, history of drug, educational background, geographic factors P = 0.042, 0.033, 0.417, 0.000, 0.000, 0.012, 0.392, 0.440, OR = 3.406, 7.511, 2.643, 42.073, 88.457, 21.680, 1.752, 5.561.When value of P < 0.05, clinical risk factors were screened. Clinical symptom scores and work, life factor score and SAS, SDS score of randomly selected patient samples was positively correlated, r = 0.816, 0.763, 0.795, 0.923, P = 0.000, indicating statistically significant.

CONCLUSIONNaval forces functional dyspepsia prevalence was higher than the general population, which risk factors included work, life, psychological, physical fitness factors, closely related with military service and military personnel, military rank, the nature of the work, the training intensity and environment, eating habits, daily sleep time, drinking history, depression, anxiety level, age, gender, BMI index, history of gastrointestinal disease, use of drugs, high priority should be given to the risk factors listed above, the development of rational targeted programs to strengthen the cause of prevention measures.
