Abstract: The association between nocturnal enuresis (NE) and sleep disordered breathing (SDB) has been repeatedly reported, but has primarily been focused on clinical cohorts. The purpose of this study, was to assess whether SDB-related symptoms such as snoring and unrefreshing sleep in the morning are associated with NE in a large-scale community school-based survey. A cross-sectional assessment using a standard questionnaire was conducted on nearly 20 000 primary school children (5-12 years old) in Matsuyama, Japan. Associations between NE and the frequencies of snoring and unrefreshing sleep were evaluated using multivariate logistic and regression analyses. Multivariate adjusted odds ratios (95% confidence intervals) for enuresis were 1.21 (1.04 to 1.40) and 1.36 (1.07 to 1.73) in boys who snored 1 or 2 nights per week and ≥3 nights per week, respectively (P for trend <0.0001). Those for enuresis were 1.67 (1.41 to 1.99) and 1.96 (1.63 to 2.36) in boys who showed unrefreshing sleep 1 or 2 nights per week and ≥3 nights per week, respectively (P for trend <0.0001). Significant associations between NE and snoring frequency emerged among children who did not report unrefreshing sleep (P-trend for boys and girls were <0.0001 and 0.1). The pathogenic mechanisms linking snoring and unrefreshing sleep to increased risk of NE are unknown. However, snoring, a surrogate reporter of SDB, is associated with increased urine production, while unrefreshing sleep may result from disrupted sleep facilitating increased sleep pressure and elevated arousal thresholds. Thus, both SDB and unrefreshing sleep are potential independent risk factors of NE in school age children.

Abstract: With a rapidly aging society, there is increasing interest in the health of female workers in the field of care services for older adults due to increasing demands to maintain 24-h care and to support older adults without errors or accidents. Therefore, the purpose of this cross-sectional study was to examine the association between sleep-disordered breathing (SDB) and sustained attention in women caring for older adults in Japan. The study was conducted in women aged 18-67 years old working in care service facilities for older adults in Japan. The sustained attention of participants was measured by the 10-min psychomotor vigilance task (PVT). SDB was assessed based on the respiratory disturbance index (RDI), which was measured using an ambulatory airflow monitor with a polyvinylidene fluoride (PVDF) film sensor to monitor the respiratory airflow of nasal and oral breathing. The participants wore the monitor to record the breathing status while asleep at home. The severity of SDB was categorized as follows: normal, RDI < 5 events/h mild SDB, RDI 5-10 events/h and moderate-to-severe SDB, RDI ≥ 10 events/h. Of 688 women enrolled, medians of age, body mass index (BMI), sleep duration, and prevalence of hypertension tended to be higher with increasing RDI. No significant association was found between RDI and PVT parameters. However, when we limited the analysis to women with BMI ≥ 22 kg/m Our findings suggest that SDB is associated with reduced sustained attention in participants with BMI ≥ 22 kg/m

Abstract: The aim of this study was to examine the prevalence of sleep-disordered breathing (SDB) in women working in the field of aged care in Japan. A cross-sectional study was conducted for female employees aged 18-60 years in aged care facilities in Japan. The analyzed set consisted of 712 participants with complete data. SDB was determined by respiratory disturbance index (RDI), measured using an ambulatory airflow monitor with a polyvinylidene fluoride film sensor to detect nasal and oral airflow overnight at home. Based on the findings of previous studies, RDI 10 was considered equivalent to apnea-hypopnea index (AHI) 15. The prevalence of moderate-to-severe SDB (RDI ≥ 10) was 22.8%. The mean age was 38.1 years, and mean sleeping time of participants was 6.1 h. The median body mass index (BMI) was 22.0. Women with moderate-to-severe SDB (RDI ≥ 10) had a higher age, neck circumference, neck-height ratio, BMI, systolic blood pressure, and increased prevalence of hypertension, short sleepers (amount of sleep on the SDB testing day < 6 h), and habitual snorers, compared to women with no or mild SDB (RDI < 10). Our study found that women working in the aged care services in Japan were heavily burdened by SDB even though they were relatively young and slim. To prevent CVD from developing in the future, programs through which workplaces can help their employees improve their lifestyle, and early diagnosis and treatment of SDB are highly recommended.
