目的:探讨小儿肺炎发病与人体生物节律之间的关系。方法:根据肺炎患儿发病日期及出生时间,利用公式x=100Sin(360/T)_t分别计算出各个患儿发病日的生物节律值,以智力、情绪和体力的节律值分别≤|19|、≤|22|、≤|27|为临界期,若节律的绝对值大于此数,正值者为高潮期,负值者则为低潮期。结果:389例肺炎患儿中,临界期发病者(50.13%)明显高于低潮期(26.48%)和高潮期(23.39%)(X~2=74.8997,P<0.01)。体力节律处在临界期或低潮期发病的占73.52%,而情绪节律和智力节律则分别为61.44%和49.36%,X~2值分别为12.9388和47.9387,其P值均<0.01。结论:小儿肺炎多在人体生物节律的临界期发病;三种节律中以体力节律的运行情况与小儿肺炎的发病关系尤为密切。
Objective: To explore the relationship between the incidence of pneumonia in children and the biological rhythm of the human body. Methods: Based on the onset date and birth time of children with pneumonia, the circadian rhythm of each child was calculated by the formula x = 100Sin (360 / T) _t. The rhythms of intelligence, emotion and physical strength were respectively ≤ 19 | , ≤ | 22 |, ≤ | 27 | as the critical period, if the rhythm of the absolute value is greater than this number, positive for the climax, negative for the low tide. Results: Among 389 children with pneumonia, the incidence of critical stage was significantly higher than that of low tide period (26.48%) and high tide period (50.3%) (X ~ 2 = 74.8997, P <0.01). Physical rhythms accounted for 73.52% of the patients in the critical period or low tide, while emotional and intellectual rhythms were 61.44% and 49.36%, respectively. The X ~ 2 values were 12.9388 and 47.9387, respectively, with P values <0.01. Conclusions: Pediatric pneumonia mostly occurs in the critical period of human biological rhythm. The relationship between circadian rhythms and the incidence of pneumonia in children is particularly close in the three rhythms.
