Gastric dilatation-volvulus (GDV) is a life-threatening condition in dogs and other species in which the stomach dilates and rotates on itself. The etiology of the disease is multi-factorial, but explicit precipitating causes are unknown. This study sought to determine if there was a significant association between changes in hourly-measured temperature and/or atmospheric pressure and the occurrence of GDV in the population of high-risk working dogs in Texas. The odds of a day being a GDV day, given certain temperature and atmospheric pressure conditions for that day or the day before, was estimated using logistic regression models. There were 57 days in which GDV(s) occurred, representing 2.60% of the days in the 6-year study period. The months of November, December, and January collectively accounted for almost half (47%) of all cases. Disease risk was negatively associated with daily maximum temperature. An increased risk of GDV was weakly associated with the occurrence of large hourly drops in temperature that day and of higher minimum barometric pressure that day and the day before GDV occurrence, but extreme changes were not predictive of the disease.
胃扩张-扭转（GDV）是一种危及犬类及其他物种生命的疾病，在此疾病中胃会发生扩张并自身扭转。该疾病的病因是多因素的，但确切的促发因素尚不清楚。本研究旨在确定在德克萨斯州高危工作犬群体中，每小时测量的温度和/或大气压力变化与GDV的发生之间是否存在显著关联。利用逻辑回归模型估计了在特定当日或前一日温度和大气压力条件下某一天发生GDV的几率。共有57天发生了GDV，占6年研究期天数的2.60%。11月、12月和1月这几个月的病例数几乎占所有病例的一半（47%）。疾病风险与每日最高温度呈负相关。GDV风险增加与当日每小时温度大幅下降以及当日和GDV发生前一日最低气压较高的情况存在弱关联，但极端变化并不能预测该疾病。
