Both hip fractures and vitamin D (25-hydroxyvitamin D (25-OHD)) deficiency are more common in winter in regions with temperate climates, but few data exist for a sub-tropical climate. In a South East Queensland tertiary hospital over a 7-year period, there were significantly more hip fractures in winter than the other three seasons (analysis of variance P = 0.003), with associated higher frequency of 25-OHD deficiency - 42.5% in winter compared to 28.5% in summer, odds ratio 1.86 (95% confidence interval 1.35-2.56), P = 0.0001. Seasonality of hip fracture and 25-OHD deficiency occurs even in a sub-tropical climate.
在温带气候地区，冬季髋部骨折和维生素 D（25-羟维生素 D（25-OHD））缺乏更为常见，但在亚热带气候地区的数据很少。在昆士兰州东南部的一家三级医院，7 年期间冬季髋部骨折的发生率明显高于其他三个季节（方差分析 P = 0.003），与 25-OHD 缺乏相关的频率也更高 - 冬季为 42.5%，夏季为 28.5%，比值比为 1.86（95%置信区间 1.35-2.56），P = 0.0001。即使在亚热带气候地区，髋部骨折和 25-OHD 缺乏也存在季节性。
