目的:探讨分娩胎龄、出生体重与扭转阶段全身运动质量(GMs)的关系。方法:①以2011年10月~2012年8月来本院儿保门诊随诊的201例扭转阶段高危儿为研究对象,根据分娩胎龄分为早产组、足月组。根据出生体重分为<2 500 g组、≥2 500 g组。②比较各组患儿GMs不同结果数量。③分析GMs结果与出生体重、分娩胎龄的关系。结果:①正常扭转运动130例,发生率为64.68%,单调性扭转运动(PR)56例,发生率为27.86%,痉挛-同步性扭转运动(CS)15例,发生率为7.46%。②早产组正常扭转运动数量明显少于足月组,PR和CS数量明显多于足月组。<2 500 g组,正常扭转运动数量明显少于≥2 500 g组,PR、CS数量明显多于≥2 500 g组。③扭转阶段GMs结果与出生体重(P=0.01)和分娩胎龄(P=0.01)具有明显相关性。结论:①早产及低出生体重均是扭转阶段异常GMs的高危因素。②分娩胎龄、出生体重与GMs结果具有明显相关性,即出生体重越轻、分娩胎龄越小,扭转阶段GMs异常程度越高,应及早筛查、干预。
Objective: To investigate the relationship between gestational age, birth weight and total body movement mass (GMs) during the twisting phase. Methods: ① From October 2011 to August 2012, 201 high risk infants with reversal stage were enrolled in this study. According to the gestational age, they were divided into preterm group and term group. According to birth weight is divided into <2 500 g group, ≥ 2 500 g group. ② Comparison of different groups of children with GMs results. ③ analysis of GMs results and birth weight, childbirth gestational age. Results: ① There were 130 cases of normal torsion, the incidence rate was 64.68%, 56 cases of monotonic torsion (PR), the incidence rate was 27.86%, 15 cases of spasticity - synchronous torsion movement (CS), the incidence rate was 7.46%. ② The number of normal torsion in preterm group was significantly less than that in term group, and the number of PR and CS was significantly more than that in term group. <2 500 g group, the number of normal torsion movement was significantly less than ≥2 500 g group, PR, CS number was significantly more than ≥2 500 g group. (3) There was a significant correlation between the results of GMs in twisting phase and birth weight (P = 0.01) and laboring gestational age (P = 0.01). Conclusions: (1) Both preterm birth and low birth weight are the risk factors of abnormal GMs in the twisting phase. The gestational age, birth weight and GMs results have obvious correlation, that is, the birth weight is lighter, the smaller the gestational age, the more abnormal phase of GMs in the twisting phase should be screened and intervened as soon as possible.
