Pneumothorax is defined as air in pleural space. The etiology of spontaneous pneumothorax (SP) is still under investigation and, despite many studies, remains uncertain. The aim of this study was to investigate the effects of the lunar cycle and daily weather changes on SP development.
The data of patients admitted to our clinic with SP were analysed retrospectively. The daily atmospheric pressure, relative ratio of humidity and temperature in degrees Celsius of each day were obtained. The mean values for each day, from the first to the 29th day, of the synodic lunar cycle (SLC) were calculated for the five-year study period. The attacks were allocated to the appropriate day of an ideal 29-day SLC, irrespective of the calendar date.
A total of 131 patients who were admitted to our hospital with SP (130 males and 1 female with an average age of 32.4±12.2) were included in this study. The number of patients with SP showed a statistically significant correlation with mean atmospheric pressure (p=0.005), relative humidity (p=0.007) and outdoor temperature (p=0.02) but not with the SLC.
SP is significantly influenced by weather-related factors. Changes in atmospheric pressure, humidity and outdoor temperature had obvious effects on the development of SP. However, the SLC had no effect on SP.
气胸被定义为胸膜腔内出现气体。自发性气胸（SP）的病因仍在研究中，尽管进行了许多研究，但仍不明确。本研究的目的是调查月周期和每日天气变化对SP发病的影响。
回顾性分析我院收治的SP患者的数据。获取每日的大气压力、湿度相对比和摄氏度温度。在为期五年的研究期间，计算朔望月周期（SLC）从第1天到第29天每天的平均值。不论日历日期，将发作分配到理想的29天SLC的相应日期。
本研究纳入了我院收治的131例SP患者（130例男性和1例女性，平均年龄32.4±12.2岁）。SP患者数量与平均大气压力（p=0.005）、相对湿度（p=0.007）和室外温度（p=0.02）呈显著统计学相关性，但与SLC无关。
SP受天气相关因素的显著影响。大气压力、湿度和室外温度的变化对SP的发病有明显影响。然而，SLC对SP没有影响。
