OBJECTIVE: To explore the correlation between snoring and carotid artery plaques in the elderly population. METHOD: Sixty-seven patients with snoring and 61 healthy volunteers accepted questionnaire on sleep apnea were analyzed in the survey. Multivariate Logistic regression analysis was used to analyze the factors affecting carotid artery plaques. RESULT: Among the non-snorers (n = 61), mild snorer (n = 18), moderate snorers (n = 24) and severe snorers (n = 25) groups, the prevalence of carotid artery plaques in four groups were 19.7%, 44.4%, 62.5%, 84.0% respectively. There was statistically significant differences between groups. After multivariable adjustment, the moderate and severe snorers were still risk factors affecting carotid artery plaques, the OR (95% CI) values were 4.378 (1.181-16.225), and 19.572 (3.316-115.528) respectively. CONCLUSION The moderate and severe snoring in the elderly population were relevant to the increased prevalence of carotid artery plaques, and was a risk factor on carotid artery plaques.

Obstructive sleep apnea syndrome (OSAS) is a complicated chronic disease caused by certain reasons, characterized by obstruction of the upper airway and apnea or hypopnea during sleep, which can be followed by anoxia, snoring and daytime sleepiness. Recent studies have shown that hypertension is closely connected to OSAS. OSAS can lead to hypertension by several possible mechanisms. The diagnosis of OSAS mainly depends on the medical history, sign, polysomnogram (PSG) result and the frequency of apnea and hypopnea. OSAS can be relieved by continuous positive airway pressure (CPAP), oral orthodontic treatment, medicine, change of lifestyles and others. This brief review focuses on the mechanism of hypertension due to OSAS and the diagnosis criteria and treatment of OSAS.

OBJECTIVETo study the prevalence of snoring and obstructive sleep apnea-hypopnea syndrome (OSAHS) and its high risk factors in Guangxi Zhuang Autonomous Region.

METHODSFrom January 2003 to March 2005, a total number of 11,163 persons aged > or =14 years Zhuang minority living in Guangxi (from Guinan, Guizhong and Guibei) were surveyed. Questionnaire was administered to draw information. Polysomnography(PSG) and in-home polygraphy were performed on participants being studied and who had reported snoring.

RESULTSAmong all the surveyed people, 2940reported snoring with a prevalence of 27.3%. 448 (320 males and 128 females) people reported OSAHS with prevalence as 4.3% (5.9% in males and 2.5% in females). From 14 to 60 year olds, the prevalence of snoring and OSAHS increased with age. Among those above 60 years of age, both the prevalencerates ofsnoring and OSAHS werereduced with age. Among all the study population, 260 (21.6%) had habitual OSAHS a nd 188 (10.8%) hadoccasional OSAHS. The high risk factors of OSAHS were: position during sleep, disease of nose, drinking alcohol, smoking, gender, body mass index (BMI) and age.

CONCLUSIONThe prevalence rates of snoring and OSAHS were 27.3% and 4.3% respectively. From 14 to 60 years of age, the prevalence rates of snoring and OSAHS were increasing with age while from 60 years of age on, the prevalence of snoring and OSAHS reduced with age. The prevalence rates of snoring and OSAHS in males were higher than females. The high risk factors of OSAHS were position during sleep,disease of nose, drinking, smoking,gender, BMI and age.

Despite apparent similarities to adult sleep medicine, the disorders of paediatric sleep medicine have a distinct epidemiology and pathophysiology. During childhood, the physiology of sleep develops and matures, resulting in changing patterns of normal behaviours and of sleep disorders. Through a fictional case scenario, this article aims to convey the range and complexity of disorders that may be encountered and the various investigations and treatments available to the paediatric sleep physician.

OBJECTIVETo investigate the prevalence of snoring in school age children from Changsha City, and study the correlation of snoring with attention deficit and hyperactivity-impulsivity.

METHODSA total of 1 736 children aged 6 to 12 years were randomly sampled from five districts in Changsha City. Their parents completed the questionnaires about children's sleep conditions and the Attention Deficit Hyperactivity Disorder Diagnostic Scale-Parent Version.

RESULTSThe total incidence rate of frequent snoring was 5.7%. Boys had higher incidence of frequent snoring than girls (7.5% vs 3.8%; x2=18.782, p<0.01). The incidence of snoring in the 6-to 9-year-old group was higher than that of the 10-to 12-year-old group (x2=9.666, P<0.01). The incidence of daytime sleepiness in the snoring group was higher than that in the non-snoring group (31.5% vs 25.9%; x2=6.678, p<0.01). The incidences of larynx choking, sleep apnea, mouth breathing, hyperhidrosis, and awaking for unknown reasons or awaking by choke in the frequent snoring group were significantly higher than in the occasional snoring and the non-snoring groups (x2=37.035, 27.745, 51.341, 30.975, 45.972 respectively; all P<0.01). The incidences of attention deficit (31.3%) and hyperactivity-impulsivity (18.2%) in the frequent snoring group were the highest, followed by the occasional snoring (16.2% and 9.9% respectively) and the non-snoring groups (13.9% and 8.8% respectively). There were significant differences in the incidence of both attention deficit (x2=20.592, p<0.01) and hyperactivity-impulsivity (x2=9.067, p<0.05) between groups.

CONCLUSIONSThere is a high incidence of snoring in school age children from Changsha City. Snoring is correlated to attention deficit and hyperactivity-impulsivity. It is essential to pay attention to the mental growth and behavioral problems in children with sleep snoring.

This review article summarises the current available literature on sleep patterns and sleep problems in Singapore children. Co-sleeping is a culturally dependent practice and its prevalence in Singapore has been determined to be 73%. Co-sleeping is not associated with significant sleep problems in Singapore children. Snoring and habitual snoring occur in 28.1% and 6.0% of Singapore children, respectively. Habitual snoring in Singapore children was significantly associated with obesity, allergic rhinitis, atopic dermatitis, maternal smoking and breastfeeding. Atopy was the strongest risk factor for habitual snoring in Singapore, and the effect was cumulative. Children attending psychiatric services in Singapore may also have sleep disorders, the highest prevalence being in children with attention deficit hyperactivity disorder. The knowledge on childhood sleep disorders (including obstructive sleep apnoea) amongst the public, patients, parents and future doctors in Singapore are inadequate and there is an urgent need for increased education in this area given the importance of good sleep in children. There is also a need to change parental attitudes about sleep disorders and encourage early medical consultation.

OBJECTIVE: To survey the prevalence of obstructive sleep apnea-hypopnea syndrome(OSAHS) in adults aged over 60 years in Dongying city,and analyze the risk factors and the extent of damage to the quality of life for the elderly to provide the basis for prevention and treatment of OSAHS people. METHOD: One thousand subjects were derived from a random cluster sampling in seven districts of Dongying city:they were asked to answer the questions from questionnaires. According to the questionnaire scoring, 100 subjects in high-risk group were selected randomly to make polysomnography monitoring for a whole night,so that the prevalence of the disease was calculated and the related risk factors were analyzed; elderly patients diagnosed with OSAHS were asked to assess the quality of life assessment questionnaire by face to face to understand the quality of life dimensions injury. RESULT: The actual number of completed surveys was 934, and the efficiency was 93.4%. The estimated prevalence of OSARS in elder people defined by apnea-hypopnea index (AHI ≥ 5) was 32.5%; Multivariate analysis revealed that age smoking, family snoring,neck circumference, waist circumference, and abnormality of the upper airway were respectively independent risk factors of OSAHS,and the abnormalities of the upper airway had the most obvious impact on AHI. The damage caused by OSAHS to the quality of life for elderly people followed their daily work life, social relationships, symptoms, alertness, emotional, general health, symptoms. CONCLUSION The estimated prevalences of OSAHS in elder people were high. Actively promoting good habits to older people, weight loss, early detection and correct upper airway abnormalities may reduce the estimated prevalence of OSAHS. In the treatment process, the patient's physician should pay attention to their emotional and groom their psychological problems to improve the quality of life in elder people.

Objective: To explore the correlation between sleep status and frailty in adults aged 30-79 years in China, and explore the potential effect modification of general and central obesity. Methods: Based on the baseline data of the China Kadoorie Biobank, we used multinomial logistic regression to analyze the correlation between long and short sleep duration, insomnia disorder, snoring, and unhealthy sleep score with risks of pre-frailty and frailty. Both overall and obesity-stratified analyses were performed. Result: Among the 512 724 participants, 2.3% had frailty and 40.1% had pre-frailty. There was a U-shaped relationship between sleep duration and frailty score. Short (OR=1.21, 95%CI: 1.19-1.23) or long sleep duration (OR=1.19, 95%CI: 1.17-1.21), insomnia disorder (OR=2.09, 95%CI: 2.02-2.17), and snoring (OR=1.61, 95%CI: 1.59-1.63) were all positively correlated with pre-frailty, and dose-response relationships were observed between unhealthy sleep score and pre-frailty (P for trend<0.001), with OR values of 1.46 (1.44-1.48), 1.97 (1.93-2.00) and 3.43 (3.21-3.67) respectively for those having unhealthy sleep score of 1 to 3. These sleep problems were also positively correlated with frailty. Compared with the overweight or obesity group, stronger relationships were observed between short sleep duration and frailty or pre-frailty and between insomnia disorder and pre-frailty, while the relationships between snoring and frailty and pre-frailty were weaker in the participants with normal weight (P for interaction <0.007 for all). We also observed similar effect modification by central obesity. Conclusion: Long or short sleep duration, insomnia disorder, snoring and higher unhealthy sleep scores were positively correlated with pre-frailty or frailty, general and central obesity status could modify the relationships.

OBJECTIVETo investigate the prevalence rates of snoring disease and obstructive sleep apnea-hypopnea syndrome (OSAHS) and their risk factors among truck drivers in Guangzhou, China.

METHODSA questionnaire survey was conducted in 374 truck drivers who were selected from 5 logistics companies in Guangzhou by cluster sampling. Those who had potential snoring disease or OSAHS underwent polysomnographic monitoring at night. The obtained data were analyzed to calculate the prevalence rates of snoring disease and OSAHS and determine the risk factors for OSAHS.

RESULTSA total of 335 subjects completely questionnaires, with a response rate of 90%. Among the 335 subjects, 125 (37.3%) had habitual snoring, and 42 (12.5%) had OSAHS according to the diagnostic criterion (apnea-hypopnea index ≥ 5 times/h). The multiple stepwise regression analysis showed that the risk factors for OSAHS were age, alcohol use, family history of snoring, body mass index, and upper airway abnormality. Of the subjects with grade ≥ 2 snoring and OSAHS, 65.4% often felt sleepy when driving during daytime, and 42% had suffered or nearly suffered traffic accidents due to sleepiness when driving. Moreover, 95.5% (320) of the 335 truck drivers did not consider snoring a disease, and 98% did not think traffic accident might be related to snoring.

CONCLUSIONThe prevalence rates of snoring disease and OSAHS among truck drivers are 37.3% and 12.5%, respectively. Therefore, prevention measures should be established according to the epidemiological characteristics to help the truck drivers realize the hazards of snoring disease and OSAHS, thus minimizing the prevalence and hazards of the diseases.

BACKGROUND: We aim to explore the association between self-reported snoring and hypertension among adults aged 30-79 in Chongqing, China. METHODS: A total of 23,342 individuals aged 30-79 were included at baseline from August 2018 to January 2019, and the final sample size for the analysis was 22,423. Face-to-face interviews and physical examinations were conducted by trained investigators. Logistic regression was performed to study age-specific and gender-specific associations between snoring and hypertension. RESULTS: Frequent snoring was associated with the risk of hypertension for each age and gender group, and the frequency of snoring was positively correlated with the risk for hypertension. For the three age groups (< 45, 45-59, ≥ 60), compared with the non-snoring group, those who snore often had a 64.5%, 53.3%, and 24.5% increased risk of hypertension (< 45: OR = 1.65, 95%CI 1.34-2.02; 45-59: OR = 1.53, 95%CI 1.37-1.72; ≥ 60: OR = 1.25, 95%CI 1.09-1.42), respectively. For men and women, those who snore often had a 46.8% and 97.2% increased risk of hypertension, respectively, than the non-snoring group (men: OR = 1.47, 95%CI 1.33-1.63; women: OR = 1.97, 95%CI 1.75-2.23). CONCLUSIONS People who snore frequently should pay close attention to their blood pressure levels in order to achieve early prevention of hypertension, particularly for snorers who are female and aged under 45; importance should be attached to their blood pressure control.
