Objective:To explore the improvement effect of individualized intervention on reducing the risk of gastroesophageal reflux disease (GERD) by analyzing the related risk factors in fighter pilots.Methods:The health risk data of 164 fighter pilots of the Air Force were randomly selected by the paired data study. The risk assessment and prediction model was established to analyze the changes in the risk grades of GERD among the pilots before and 30 months after individualized interventions (follow-up every 6 months).Results:Among the risk factors of GERD in pilots (high-fat and high-protein diets, catching cold, excessive fatigue and annoyance), annoyance and catching cold were significantly improved after intervention ( χ2=4.11, 8.60, P=0.043, 0.003). The number of participants at high risk of GERD decreased significantly, and the difference was statistically significant ( χ2=13.53, P<0.001). The results of 5 follow-ups showed that there was a significant difference in the risk scores of GERD by intervention ( P=0.003). At the fifth follow-up after intervention, the risk score of GERD was significantly decreased compared with that before intervention, at the first follow-up after intervention and at the second follow-up after intervention ( P<0.001,=0.040, 0.010). Conclusion:Individualized interventions based on the risk assessment and prediction system have positive effects on reducing the risk of GERD in fighter pilots.

Objective To analyze the risk factors of neck pain in fighter pilots . Methods Cluster random sampled fighter pilots were investigated by a cross-sectional survey .The questionnaire included daily neck pain ,as well as such exposure factors as personal general conditions ,life styles and flight traing styles .The subjects with daily neck pain were constituted to the neck pain group and those without daily neck pain were selected as the control group .The differences in age ,body mass index ,lifestyle and training styles were compared between two groups .Then the risk factors were analyzed by a Logistic regression model . Results Data of 429 fighter pilots were validated and were analyzed .The prevalence of daily neck pain was 30 .1% .The differences on the proportions of age over 35 yr ,sleep disorders ,improper measures against annoyance ,sedentary habit ,more than 4 hours of consumer electronics watching per day ,more than 2 hours of sustained monitor watching frequently , mattress too hard , long-term flight , vibration influence in flight , insufficient protection measures against +Gzload ,and no massage relaxation after flight showed statistically significance between two groups (χ2＝5 .662～32 .128 , P＜0 .05) .Totally 6 latent risk factors of neck pain were concerned by Logistic regression model .The descending risk orders of the factors were the age over 35 yr (OR＝11 .397) ,sleep disorders (OR ＝ 3 .013 ) , improper measures against annoyance (OR ＝ 2 .758 ) , awkward neck posture during flight (OR＝2 .618) ,watching consumer electronics more than 4 hours per day (OR＝2 .192) and continuously watching monitor more than 2 hours frequently (OR＝1 .899) . Conclusions The prevalence of daily neck pain in fighter pilots was comparatively high .Life styles effectively influence the invasion of neck pain in fighter pilots according to the study .Insufficient work and rest alternation and unreasonable emotion regulation would be the important risk factors to the daily neck pain in fighter pilots .
