Analysis on the related factors of obstructive sleep apnea hypopnea syndrome among the elderly in Changsha / 中国医师杂志

ABSTRACT

Objective:To explore the possible associated factors and parameters of obstructive sleep apnea hypopnea syndrome (OSAHS) among the elderly in Changsha.Methods:In the investigation of chronic diseases among the elderly in Changsha and the promotion and popularization of community standardized prevention and control, 500 elderly people >65 years old in Yuhua District of Changsha City were selected by multi-stage sampling method. Polysomnography (PSG) was used to detect sleep apnea hypopnea syndrome and collect physical examination indexes. A total of 70 cases met the diagnostic criteria of OSAHS apnea hypopnea index were divided into mild (42 cases), moderate (16 cases) and severe (12 cases). 20 cases of non OSAHS were selected as control group. The general information, PSG level and dynamic blood glucose level were compared between the two groups. Pearson correlation analysis was performed between ambulatory blood glucose level and sleep apnea hypopnea index in OSAHS patients.Results:There were significant differences in body mass index (BMI), girth ratio, smoking history, drinking history, apnea frequency, longest duration of hypoventilation, lowest oxygen saturation, supine apnea index and non supine apnea index between OSAHS group and control group ( P<0.05). The amplitude of blood glucose fluctuation was positively correlated with sleep apnea hypopnea index ( P<0.05). Conclusions:Among the many associated factors on OSAHS, BMI and the ratio of neck circumference to length and body position have the most notable influence. Patients with OSAHS are more prone to blood glucose fluctuations, and gradually worsen with the progression of OSAHS. Therefore, we should take targeted intervention measures.
