目的 分析歼击机飞行员胃食管反流的相关危险因素，探讨个体化干预对降低飞行员胃食管反流发病风险的改善作用。 方法 采取配对资料研究方法，随机整群抽取164例空军歼击机飞行员的健康风险数据，利用风险评估预测模型，分析实施个体化干预前、干预30个月后（每6个月随访1次）飞行员胃食管反流发病风险等级变化情况。 结果 飞行员发生胃食管反流症状的危险因素（高蛋白高脂肪饮食、受凉、过度疲劳、苦闷烦恼）中苦闷烦恼、受凉在干预后发生了明显改善（χ2=4.11、8.60，P=0.043、0.003）。干预后胃食管反流发病高风险的人数比干预前明显降低，差异有统计学意义（χ2=13.53，P<0.001）。随访结果显示，干预后5次随访与干预前胃食管反流发病风险分值差异有统计学意义（P=0.003），干预后第5次随访与干预前、干预后第1次随访和干预后第2次随访相比，胃食管反流发病风险分值明显下降（P<0.001、=0.040、0.010）。 结论 通过风险程度评估预测系统实施个体化干预措施，对降低歼击机飞行员胃食管反流发病风险具有积极价值。 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.
