儿童肥胖对肺功能的影响与肥胖程度相关,轻度肥胖儿童肺功能改变不明显,中度肥胖者补呼气量明显下降,重度肥胖时有明显的肺容量改变,主要为限制性通气功能障碍和补呼气量、肺活量、深吸气量明显降低。通气功能影响有大、小气道通气功能障碍,用力肺活量,1秒钟用力呼气量和用力肺容积75%、50%、25%时的最大呼气流速下降。肥胖易引起儿童哮喘和睡眠呼吸暂停综合征、上气道梗阻及反复呼吸道感染。该文就肥胖对儿童肺功能的影响及呼吸系统疾病作一综述。
The effects of childhood obesity on lung function were related to the degree of obesity. The changes of lung function in children with obesity were insignificant, the obesity of moderate obesity significantly decreased the expiratory volume of exhaled breath, and the significant changes of lung volume in severe obesity were mainly restrictive ventilatory dysfunction And fill expiratory volume, vital capacity, deep inspiratory volume decreased significantly. Ventilatory function of large and small airway ventilation dysfunction, forced vital capacity, forced expiratory volume of 1 second and forced lung volume 75%, 50%, 25% of the maximum expiratory flow rate decreased. Obesity can cause asthma in children and sleep apnea syndrome, upper airway obstruction and recurrent respiratory tract infections. This article reviews the effects of obesity on children’s lung function and respiratory diseases.
