Risk Of Obstructive Sleep Apnea Research Articles

Association between the Risk of Obstructive Sleep Apnea and Lung Function: Korea National Health and Nutrition Examination Survey.

Obstructive sleep apnea (OSA) is a prevalent sleep disorder associated with various health issues. Although some studies have suggested an association between reduced lung function and OSA, this association remains unclear. Our study aimed to explore this relationship using data from a nationally representative population- based survey. We performed an analysis of data from the 2019 Korea National Health and Nutrition Examination Survey. Our study encompassed 3,675 participants aged 40 years and older. Risk of OSA was assessed using the STOP-Bang (Snoring, Tiredness during daytime, Observed apnea, and high blood Pressure-Body mass index, Age, Neck circumference, Gender) questionnaire and lung function tests were performed using a portable spirometer. Logistic regression analysis was applied to identify the risk factors associated with a high-risk of OSA, defined as a STOP-Bang score of ≥3. Of 3,675 participants, 600 (16.3%) were classified into high-risk OSA group. Participants in the high-risk OSA group were older, had a higher body mass index, and a higher proportion of males and ever-smokers. They also reported lower lung function and quality of life index in various domains along with increased respiratory symptoms. Univariate logistic regression analysis indicated a significant association between impaired lung function and a high-risk of OSA. However, in the multivariable analysis, only chronic cough (odds ratio [OR], 2.413; 95% confidence interval [CI], 1.383 to 4.213) and sputum production (OR, 1.868; 95% CI, 1.166 to 2.992) remained significantly associated with a high OSA risk. Our study suggested that, rather than baseline lung function, chronic cough, and sputum production are more significantly associated with OSA risk.

A pilot observation using ultrasonography and vowel articulation to investigate the influence of suspected obstructive sleep apnea on upper airway

Failure to employ suitable measures before administering full anesthesia to patients with obstructive sleep apnea (OSA) who are undergoing surgery may lead to developing complications after surgery. Therefore, it is very important to screen OSA before performing a surgery, which is currently done by subjective questionnaires such as STOP-Bang, Berlin scores. These questionnaires have 10–36% specificity in detecting sleep apnea, along with no information given on anatomy of upper airway, which is important for intubation. To address these challenges, we performed a pilot study to understand the utility of ultrasonography and vowel articulation in screening OSA. Our objective was to investigate the influence of OSA risk factors in vowel articulation through ultrasonography and acoustic features analysis. To accomplish this, we recruited 18 individuals with no risk of OSA and 13 individuals with high risk of OSA and asked them to utter vowels, such as /a/ (as in “Sah”), /e/ (as in “See”). An expert ultra-sonographer measured the parasagittal anterior–posterior (PAP) and transverse diameter of the upper airway. From the recorded vowel sounds, we extracted 106 features, including power, pitch, formant, and Mel frequency cepstral coefficients (MFCC). We analyzed the variation of the PAP diameters and vowel features from "See: /i/" to "Sah /a/" between control and OSA groups by two-way repeated measures ANOVA. We found that, there was a variation of upper airway diameter from “See” to “Sah” was significantly smaller in OSA group than control group (OSA: ∆12.8 ± 5.3 mm vs. control: ∆22.5 ± 3.9 mm OSA, p < 0.01). Moreover, we found several vowel features showed the exact same or opposite trend as PAP diameter variation, which led us to build a machine learning model to estimate PAP diameter from vowel features. We found a correlation coefficient of 0.75 between the estimated and measured PAP diameter after applying four estimation models and combining their output with a random forest model, which showed the feasibility of using acoustic features of vowel sounds to monitor upper airway diameter. Overall, this study has proven the concept that ultrasonography and vowel sounds analysis may be useful as an easily accessible imaging tool of upper airway.

Risk of Obstructive Sleep Apnea, Chronic Dizziness, and Sleep Duration.

Although it is recommended that obstructive sleep apnea (OSA) be screened for using a validated self-report questionnaire in patients experiencing dizziness, there is still a lack of research on the relationship between high risk of OSA and chronic dizziness. The study aimed to examine the relationship between the high risk of OSA and chronic dizziness and investigate how this relationship is affected by sleep duration. This cross-sectional study used data from the 8th Korea National Health and Nutrition Examination Survey (2019-2021). Adults aged 40 years or older were included and divided into two groups using the STOP-Bang Questionnaire (SBQ): a high-risk group for OSA or not. Complex samples logistic regression analyses were performed to examine the odds ratios of chronic dizziness based on the national population estimates. Our findings showed that individuals in the high-risk group for OSA were significantly more likely to experience chronic dizziness. Specifically, among subgroups based on sleep duration, the high-risk group for OSA with a short sleep duration of ≤5 hours demonstrated the highest odds of chronic dizziness, showing a significantly 2.48-fold increased likelihood compared to the non-high risk for OSA with a sleep duration of 5-9 hours. The SBQ can be beneficial when other causes do not explain chronic dizziness, helping to rule in the possibility of OSA. Educating individuals suspected of having OSA or who have been diagnosed with OSA about the importance of adequate sleep duration may help reduce the risk of chronic dizziness.

Prevalence of Obesity among Adults Visiting Otorhinolaryngology Clinics for Snoring

Abstract Introduction: This study aims to assess the prevalence of obesity and to estimate the risk of obstructive sleep apnea (OSA) among adults visiting otorhinolaryngology (ORL) clinics for snoring. Methods: We conducted a retrospective chart review of adult patients who visited ORL clinics at King Fahd Military Medical Complex for snoring in the period between October 2019 and March 2022. We utilized STOP and STOP-BANG screening tools to stratify OSA risk in the included subjects. Results: Eighty-five patients were included in this study. Most of the subjects were male (80%). Obesity was detected in 63 (74.1%) of the included subjects. Seventy-seven subjects (90.6%) were independently at risk of OSA based on the STOP-BANG questionnaire and STOP questionnaire. Conclusion: Obesity is common in adults visiting ORL clinics for snoring. The rate of OSA risk is high among adult patients visiting ORL clinics for snoring. Therefore, it is important for ORL practitioners to utilize OSA risk assessment tools and to have enough knowledge or access to sleep medicine clinics for diagnostic and therapeutic purposes.

Association of the combination of obstructive sleep apnea risk and sleep duration with ideal cardiovascular health metrics in patients undergoing hemodialysis

BackgroundThe purpose of this study was to explore the separate and combined associations of obstructive sleep apnea (OSA) risk and sleep duration with ideal cardiovascular health metrics in hemodialysis (HD) patients.Methods470 HD participants (average: 59.48 ± 12.89 y, 281 men) were included in this study. Sleep duration was measured as self-reported average sleep time during the previous month. The OSA risk was assessed using the STOP-BANG questionnaire. Participants were divided into three groups based on the number of ideal cardiovascular health (CVH) metrics: 0–2,3–4, and 5–7. Ordinal logistic regression was conducted to model the associations of CVH metrics with sleep duration, OSA risk, and their combined effects by adjusting for specific covariates.ResultsAfter adjusting for covariates, short sleep duration (< 7 h) (OR = 0.53; 95% CI [ 0.30, 0.92]) and OSA risk (OR = 0.58; 95% CI [0.32, 0.83]) were negatively associated with better CVH (ideal vs. intermediate; intermediate vs. poor), respectively. For HD patients with both short sleep duration and OSA risk, the odds of ideal CVH metrics were reduced by 72% (odds ratio 0.28 [95% CI 0.13, 0.60]).ConclusionsShort sleep duration and OSA risk are separately and jointly associated with poor CVH in hemodialysis patients. Suitable interventions for sleep may minimize the risk of developing cardiovascular disease.

Evaluation of a Pre-operative clinic's sleep apnea screening

BackgroundThis quality improvement (QI) project aimed to evaluate the process and outcomes of utilizing the STOP-BANG questionnaire (SBQ) to screen patients for sleep apnea in a pre-operative clinic. Studies outside the United States show that there is a greater risk for obstructive sleep apnea (OSA) among Asian ethnicity compared to Whites; thus, this project also aimed to describe the SBQ scores of a subset of Asian Americans not referred for a sleep study and determine the number of potential referrals if the body mass index (BMI) threshold in their SBQ scores is modified. MethodsA retrospective medical records review identified patients referred for a sleep study at the pre-operative clinic, described the sleep study outcome results, and identified gaps in the referral process that future QI projects can address. The records review also identified SBQ scores of Asian Americans not referred for a sleep study. Their scores were recalculated using a lower BMI threshold to determine the proportion of those who could have been referred. ResultsThere were 72,413 patient encounters at the pre-operative clinics from January 2019 to December 2021; 279 patients were referred for a sleep study. Only 103 (36.92 %) completed the test. There were 34 (33.01 %) confirmed to have severe sleep apnea, 28 (27.18 %) with moderate sleep apnea, 29 (28.16 %) with mild sleep apnea, and 12 (11.65 %) with no sleep apnea. Of the 176 (63.08 %) sleep study referrals not completed, the most common reasons for non-completion were issues with timely scheduling, educating patients to encourage study completion, and handling insurance denials. The mean BMI of the 1,560 Asian Americans not referred for a sleep study was 25.42 kg/m2, and only 2.31 % had a BMI > 35 kg/m2. Among the 162 Asian Americans with a history of sleep apnea, only 14.81 % had a BMI > 35 kg/m2. Adjusting the BMI threshold of SBQ increased the number of Asian Americans who could be referred for a sleep study by 1.35 % and 2.12 % if using a cut-off of > 30 kg/m2 and > 28 kg/m2, respectively. ConclusionsScreening of OSA using the SBQ in a pre-operative clinic effectively identified patients at high risk for sleep apnea. The low completion rate of sleep study referrals shows a gap in the referral process that requires improvement. Asian Americans with sleep apnea have lower BMIs. Attention to BMI thresholds would increase the identification of sleep apnea in this vulnerable population.

Composite dietary antioxidant index and sleep health: a new insight from cross-sectional study

BackgroundLow-quality sleep and obstructive sleep apnea (OSA) can result in series of chronic diseases. Healthy diet has been considered as an effective and simple strategy to optimize sleep quality. However, current evidence on the correlation of dietary composite antioxidant intake with sleep health remained obscure.Aim of the studyTo determine the relationship of composite dietary antioxidant index (CDAI) and sleep health.MethodsCross-sectional analyses were based on National Health and Nutrition Examination Survey (NHANES) 2005–2008. Dietary consumption was assessed by trained staff using 24-h diet recall method and CDAI was calculated based on previous validated approach that included six antioxidants. Sleep-related outcomes were self-reported by a set of questionnaires and classified into OSA, day sleepiness, and insufficient sleep. Weighted logistic regression was conducted to calculate odds ratios (ORs) and 95% confidence intervals (CIs). Restricted cubic spline (RCS) regressions were also used to evaluate the dose-response of CDAI and three sleep-related outcomes.ResultsA total of 7274 subjects included (mean age: 46.97 years) were enrolled in our study, including 3658 were females (52.54%) and 3616 were males (47.46%). Of them, 70.6%, 29.51%, and 35.57% of the subjects reported that they had OSA, day sleepiness and insufficient sleep, respectively. Logistic regression showed the highest quartile of CDAI was inversely associated with the risk of OSA (OR: 0.69, 95%CI: 0.49–0.97), day sleepiness (OR: 0.64, 95%CI: 0.44–0.94) and insufficient sleep (OR: 0.68, 95%CI: 0.50–0.92) compared with the lowest quartile. RCS showed linear relationship of CDAI and insufficient sleep but non-linear relationship of CDAI with OSA and day sleepiness.ConclusionsOur results show that CDAI was non-linearly associated with lower risk of OSA and day sleepiness whereas a linear inverse association between CDAI and insufficient sleep was observed. These findings implicate that combined intake of antioxidants could be a promising and effective approach to optimize sleep quality for public.

CPAP may promote an endothelial inflammatory milieu in sleep apnoea after coronary revascularization

Continuous positive airway pressure (CPAP) has failed to reduce cardiovascular risk in obstructive sleep apnoea (OSA) in randomized trials. CPAP increases angiopoietin-2, a lung distension-responsive endothelial proinflammatory marker associated with increased cardiovascular risk. We investigated whether CPAP has unanticipated proinflammatory effects in patients with OSA and cardiovascular disease. Patients with OSA (apnoea-hypopnea index [AHI] ≥15 events/h without excessive sleepiness) in the Randomized Intervention with CPAP in Coronary Artery Disease and OSA study were randomized to CPAP or usual care following coronary revascularization. Changes in plasma levels of biomarkers of endothelial (angiopoietin-2, Tie-2, E-selectin, vascular endothelial growth factor [VEGF-A]) and lung epithelial (soluble receptor of advanced glycation end-products [sRAGE]) function from baseline to 12-month follow-up were compared across groups and associations with cardiovascular morbidity and mortality assessed. Patients with OSA (n=189; 84% men; age 66±8 years, BMI 28±3.5kg/m2, AHI 41±23 events/h) and 91 patients without OSA participated. Angiopoietin-2 remained elevated whereas VEGF-A declined significantly over 12 months in the CPAP group (n=91). In contrast, angiopoietin-2 significantly declined whereas VEGF-A remained elevated in the usual care (n=98) and OSA-free groups. The changes in angiopoietin-2 and VEGF-A were significantly different between CPAP and usual care, whereas Tie-2, sRAGE and E-selectin were similar. Greater 12-month levels of angiopoietin-2 were associated with greater mortality. Greater CPAP levels were associated with worse cardiovascular outcomes. Greater CPAP levels increase proinflammatory, lung distension-responsive angiopoietin-2 and reduce cardioprotective angiogenic factor VEGF-A compared to usual care, which may counteract the expected cardiovascular benefits of treating OSA.

The Effectiveness of Continuous Positive Airway Pressure for Treating Obstructive Sleep Apnoea in Pregnancy: A Systematic Review

(Aust N Z J Obstet Gynaecol 2023. 2023;63(3):290–300) Obstructive sleep apnea (OSA) is characterized by recurrent pauses in breathing during sleep due to upper airway collapse, resulting in decreased oxygen levels. OSA affects around 10.5% of parturients during early pregnancy and up to 30% at term. In pregnancy, OSA is associated with an increased risk for gestational hypertension, pre-eclampsia, and gestational diabetes. Infants born to mothers with OSA may have a lower birth weight and are at increased risk for premature delivery and neonatal intensive care unit admission. Baseline obesity increases the risk of OSA during pregnancy, with lifestyle modifications being the standard treatment, though their influence on maternal outcomes is limited. Continuous positive airway pressure (CPAP) is an effective OSA treatment; however, little research exists on the impact of CPAP on either maternal or fetal outcomes. This systematic review sought to investigate if the use of CPAP improved outcomes for pregnant women with or at risk of OSA.

Association between risk of obstructive sleep apnea severity and risk of severe COVID-19 symptoms: insights from salivary and serum cytokines.

Obstructive sleep apnea (OSA) can adversely affect the immune response through clinical factors such as hypoxia, inflammation, and sleep disturbance. Since SARS-CoV-2 heavily relies on local and systemic host immune responses, this study aims to examine the links between the severity of OSA risk, cytokine levels, and the severity of symptoms associated with SARS-CoV-2 infection. Saliva and blood samples from 50 COVID-19 patients and 30 non-infected hospital staff members were collected. Using Luminex multiplex analysis, 65 blood and salivary cytokines were examined from the collected samples. Ordinal logistic regression analysis was utilized to examine the association between the self-reported risk of OSA, assessed through the STOP-Bang questionnaire, and the likelihood of experiencing severe symptoms of COVID-19. Mann-Whitney test was then performed to compare the cytokine levels between individuals with moderate to severe risk of OSA to those with a mild risk of OSA. Ordinal logistic regression analysis revealed that individuals with a moderate to severe risk of OSA were 7.60 times more likely to experience more severe symptoms of COVID-19 compared to those with a mild risk of OSA (OR = 7.60, 95%CI: 3.03, 19.06, p < 0.001). Moreover, among COVID-19-positive patients with a moderate to severe risk of OSA, there was a statistically significant negative correlation with serum IL-6 (p < 0.05), Eotaxin (CCL11) (p = 0.04), and salivary MIP-3α/CCL20 (p = 0.04). In contrast, individuals without COVID-19 who had a moderate to severe risk of OSA exhibited a significant positive correlation with serum IL-6 (p = 0.04). Individuals with moderate to severe risk of OSA were more likely to experience severe COVID-19 symptoms than those with mild risk for OSA. Additional analysis from the present studies revealed distinct patterns of oral and systemic immune responses between individuals with mild and moderate to severe risk of OSA. Findings from the present study underscores the importance of early detection and management of OSA to improve clinical outcomes, particularly when faced with the subsequent superimposed infection such as COVID-19.

The effect of tongue reduction for preventing adverse effects in patients undergoing class III orthognathic surgery: a three-dimensional comparative analysis.

This study aims to evaluate the potential benefits of combining tongue reduction with mandibular setback surgery in patients undergoing class III orthognathic surgery. Specifically, we investigated whether this combined approach reduced the risk of surgical relapse, condylar resorption, and airway space reduction by mitigating tongue pressure on the mandible. The study retrospectively enrolled patients who had undergone bilateral sagittal split ramus osteotomy (BSSRO) with at least 5 mm of setback and met the criteria of a body mass index > 20 kg/m2 and tongue volume > 100 mm3. The study included 20 patients with 10 in the tongue reduction group (TR, n = 10) and 10 in the BSSRO only group (SO, n = 10). The volumetric changes of the total airway space were significantly different between the TR and SO groups (p = 0.028). However, no significant differences were observed in the condylar resorption and postoperative relapse between the groups (p = 0.927 and 0.913, respectively). The difference between the resorption of the anterior and posterior segments of the condyle was also statistically insignificant (p = 0.826). Postoperative counterclockwise rotation of the proximal segment only demonstrated a significant correlation with postoperative relapse (p = 0.048). The reduction in tongue volume demonstrated a preventive effect on the reduction of the airway space after mandibular setback, although it did not yield statistical significance concerning surgical relapse and condylar volume. The counterclockwise rotation of the proximal segment might be responsible for the forward displacement of the distal segment and postoperative relapse. However, the clinical implications of this finding should be interpreted with caution owing to the limited sample size CLINICAL RELEVANCE: Tongue reduction could potentially serve as a preventive measure in preserving the airway space and might be beneficial in mitigating the risk of obstructive sleep apnea in patients with class III deformity.

Plant-based and vegetarian diets are associated with reduced obstructive sleep apnoea risk.

Obstructive sleep apnoea (OSA) and obesity commonly coexist. Weight loss and exercise are recommended management options for OSA. However, most of the current evidence on diet and OSA is focused on calorie restriction rather than diet quality. The aim of the present study was to determine the association of plant-based dietary indices (PDI) with OSA risk. Cross-sectional data from 14 210 participants of the National Health and Nutrition Examination Survey who provided dietary information using the 24-hour recall method were used. PDI - including healthy (hPDI), unhealthy (uPDI) and pro-vegetarian diet index (PVDI) - were determined. OSA risk was determined using the STOP-BANG questionnaire. Logistic regression was used to determine the relationship between dietary indices and OSA risk. Higher adherence to PDI (odds ratio (OR)Q5 versus Q1=0.81; 95% confidence interval (CI): 0.66-1.00), hPDI (OR=0.83; 95% CI: 0.69-1.01) and PVDI (OR=0.84; 95% CI: 0.68-1.05) was inversely associated with OSA risk, whereas higher consumption of an unhealthy plant-based diet (OR=1.22; 95% CI: 1.00-1.49) was positively associated with OSA. Sex differences in estimates were observed for PDI in males (OR=0.71; 95% CI: 0.56-0.90) versus females (OR=0.93; 95% CI: 0.68-1.28), hPDI in males (OR=0.90; 95% CI: 0.68-1.18) versus females (OR=0.77; 95% CI: 0.54-1.09) and uPDI in males (OR=1.13; 95% CI: 0.89-1.44) versus females (OR=1.42; 95% CI: 1.03-1.97) but not for PVDI. Higher adherence to a healthy plant-based diet is associated with reduced OSA risk, while an unhealthy plant-based diet has a positive association. The magnitude of these associations differs by sex. Further longitudinal studies are warranted.

Assessing the causal relationship between psychiatric disorders and obstructive sleep apnea: a bidirectional Mendelian randomization.

Extensive observational evidence suggests an association between psychiatric disorders (PDs) and obstructive sleep apnea (OSA), but their causal relationship remains unexplored. The objective of this study was to examine the causal relationship between PDs and OSA. Mendelian randomization (MR) analysis was conducted with summary genetic data from the FinnGen and Psychiatric Genomics Consortium (PGC). Inverse-variance weighted (IVW), MR-Egger, weighted median, and weighted mode methods were employed to ascertain causal influence. Sensitivity analysis employing various methodologies assessed the robustness of the findings. Furthermore, multivariable Mendelian randomization (MVMR) was used to clarify if the exposures independently caused OSA. MR analysis showed that genetically determined major depressive disorder (MDD) increased the risk of OSA (IVW odds ratio [OR]: 1.377, 95% confidence interval [CI]: 1.242-1.526, P = 1.05×10-9). Sensitivity analysis showed no evidence of pleiotropy and heterogeneity. In MVMR, the significant association persisted after adjusting for BMI, smoking, and alcohol consumption. No conclusive evidence indicated the causal impact of other psychological characteristics on OSA. In the reverse MR analyses, there was no causal effect of OSA on PDs. This study suggests a causal effect of MDD on OSA risk. Further research is needed to confirm these findings and understand how MDD contributes to OSA development, potentially aiding in reducing OSA incidence.

The association between sedentary behavior and obstructive sleep apnea: a cross-sectional study from the NHANES (2007–2008 to 2015–2020)

BackgroundSedentary behavior (SB) may contribute to obesity and lower extremity fluid retention, which may favor the development of obstructive sleep apnea (OSA). However, linking sedentary behavior to OSA is unclear. The purpose of this study was to determine if there is an association between SB and OSA.MethodsThree typical questions in the NHANES questionnaire(①The frequency of feeling excessively sleepy per month. ②The frequency of gasping, snorting or stopping breathing per week. ③The frequency of snoring per week.) have been used for the assessment of OSA. A physical activity questionnaire(On a typical day, the amount of time you spend sitting or reclining.) was used to assess SB. This secondary analysis included National Health and Nutrition Examination Survey (NHANES) participants (unweighted = 20,115). Weighted sample and multiple logistic regression complex sample analysis techniques were used in this study.ResultsAfter adjustment for confounders, participants with SB(> 8 h/d) had a higher risk of OSA compared to SB(< 4 h/d). Stratified analysis by gender showed that there was no significant association of SB and OSA in men. However, in women, with SB(< 4 h/d) as the reference, participants with(≥ 4 h/d) had an increased risk of OSA. By age-stratified analysis, the association of SB with OSA was stronger among older participants.ConclusionAnalysis in this study showed a positive association between SB and OSA, more pronounced in women and participants older than 60 years old.

Quality of Life in Metabolic Syndrome Patients Based on the Risk of Obstructive Sleep Apnea.

Despite the impact of metabolic syndrome (MetS) and obstructive sleep apnea (OSA) on a sizeable proportion of the global population, the difference in the quality of life (QoL) between a group without risk factors for OSA and a group with risk factors for OSA among individuals with MetS is currently unclear. This study aimed to identify the determinants of QoL in patients with MetS with and without OSA risk factors and to analyze differences between these two groups. Data were extracted from the 2020 Korea National Health and Nutrition Examination Survey (KNHANES). The Rao-Scott χ2 test was performed to evaluate differences in baseline characteristics based on OSA risk factors. A t-test was performed to evaluate differences in the baseline QoL, and linear regression analysis was performed to identify the effect on the QoL of the two groups. The factors affecting QoL in the low-risk group included age, education level, and depression. The factors affecting QoL in the high-risk group were physical activity and depression. These results suggest that nursing interventions should be devised according to patients' characteristics to help improve their QoL.

Malocclusions, Sleep Bruxism, and Obstructive Sleep Apnea Risk in Pediatric ADHD Patients: A Prospective Study

Objectives: Literature presents conflicting results regarding malocclusions, Obstructive Sleep Apnea (OSA) and sleep bruxism in children with ADHD. Aim of this study was to evaluate the prevalence of these parameters. Methods: A prospective study was conducted on 40 consecutive ADHD children referred to the Paediatric Dentistry Unit of Fondazione Policlinico Universitario “A. Gemelli” IRCCS, Rome. All subjects underwent an orthodontic examination and were screened for OSA and sleep bruxism. Data were compared to a sex- and aged-matched control group. Results: Prevalence of high risk of OSA in children with ADHD was 62.5% compared to 10% in the control group (p < .00001). No differences were found in any of the occlusal variables examined between children with ADHD and controls (p > .05). An increased prevalence of sleep bruxism was observed in ADHD children (40%) compared to controls (7.5%) (p < .001). Conclusions: A higher prevalence of OSA risk and probable sleep bruxism were observed in ADHD patients compared with controls. No significant differences were observed in malocclusions d

Risk stratification for frailty, impairment and assessment of sleep disorders in community-dwelling older adults

BackgroundFrailty is associated with an increased susceptibility to functional decline, impairment, hospitalization, and mortality among the older adults. However, the potential reversibility of frailty lies in identifying modifiable factors that could prevent, mitigate, or interrupt its progression. While there is a suggestion that sleep disorders may increase the risk of frailty and impairment, the risk stratification of this relationship remains inconclusive. ObjectiveStratify the risk of frailty and impairment and investigate potential connections with sleep quality, excessive daytime sleepiness, and the risk of obstructive sleep apnea in older adults dwelling in the community. MethodsThis was a quantitative cross-sectional investigation. Frailty risk and impairment were stratified using the Frail Non-disabled Questionnaire (for impairment) and the FRAIL Scale (for Frailty). The assessment of excessive daytime sleepiness, sleep quality, and the risk of obstructive sleep apnea involved the employment of the Epworth Sleepiness Scale, Pittsburgh Sleep Quality Index, and the STOP-BANG questionnaire, respectively. ResultsA total of 109 older adults living in the urban area (86 %, p = 0.010), females (61 %; p = 0.030), median age 68 (64–75) years, with overweight (36 %, p < 0.010) and self-identified as belonging to other racial or ethnic categories (71 %, p < 0.010). According to the impairment assessment, 32 % of participants were classified as disable (p < 0.01). Conversely, as per the frailty evaluation, 33 % were pre-frail and 25 % were identified as frail. Additionally, a substantial proportion experienced poor sleep quality (80 %, p = 0.010), exhibited a moderate risk of obstructive sleep apnea (49 %, p < 0.010), and showed no signs of excessive daytime sleepiness (62 %, p < 0.010). There was a modest correlation between frailty and impairment with poor sleep quality (rho = 0.39; p < 0.001) and the risk of obstructive sleep apnea (rho = 0.26; p = 0.000). However, the was no significant relationship was observed between frailty and impairment and excessive daytime sleepiness (rho = 0.04; p = 0.660). Similarly, a modest correlation was observed between sleep quality (rho = 0.33; p < 0.001), the risk of obstructive sleep apnea (rho = 0.27; p = 0.001), and frailty. Conversely, no correlation was found with excessive daytime sleepiness (rho = 0.05; p = 0.590). Also, the poor sleep quality and the risk of obstructive sleep apnea explain 14 % of the risk of frailty in the population of community-dwelling older adults (r2 = 0.14; p = 0.04). ConclusionThis study reveals a modest risk of frailty and impairment with sleep quality and the risk of obstructive sleep apnea, but not with excessive daytime sleepiness in community-dwelling older adults.

The impact of plant-rich diets on sleep: a mini-review.

Plant-rich diets (PRDs), also referred to as plant based diets, have been shown to have beneficial effects on various chronic diseases and all-cause mortality. However, limited data are available on the effect of such diets on sleep and sleep disorders. In this review article, we explore existing evidence and potential mechanisms by which PRDs may impact sleep and sleepiness. High-fat diets are associated with drowsiness, while fiber-rich diets improve sleep quality. Anti-inflammatory diets may benefit patients with sleep disturbances, and diets rich in tryptophan and serotonin precursors may improve sleep quality. Isoflavones and polyphenols present in PRDs may also have a positive impact on sleep. Furthermore, diets rich in plants may reduce the risk of obstructive sleep apnea and associated daytime sleepiness. Overall, the current knowledge about PRDs in sleep and sleep disorders is limited, and further research is needed to explore the potential advantages of this dietary approach in sleep disorders.

(332) Predictors of being at High Risk for Obstructive Sleep Apnea in Men Presenting for Low Testosterone Evaluation

Abstract Introduction Obstructive sleep apnea (OSA) is a common condition and is more common in men with obesity and low testosterone (T). In men with OSA, T therapy is associated with the development of polycythemia (POLY). It has been shown that men with OSA have a higher risk of POLY with T therapy. Objective We aimed to identify the predictors of being at high risk for OSA in men presenting for low T assessment. Methods The study population included men undergoing low T assessment who completed the OSA risk assessment questionnaire, the STOP-BANG (SB). SB contains 8 questions: STOP (Snoring, Tiredness, Observed apnea during sleeping and high blood Pressure); BANG (BMI ≥ 35, Age ≥ 50, Neck circumference ≥ 17 inches, Gender). Each question is scored as yes (1) or no (0) and is scored 0-8. Using this score, patients are categorized as low risk of OSA (score 0-2), intermediate risk (score 3-4), or high risk (score ≥ 5 or ≥ 3 plus a BMI ≥ 35 or a neck circumference ≥ 17 inches). We also measured total T and free T levels, hematocrit (HCT), and recorded BMI and demographics. Multivariable analysis (MVA) was performed to define predictors of having a high risk of OSA. Parameters in the model included: age, comorbidities (hypertension, diabetes, dyslipidemia, coronary arterial disease), total T, HCT, and BMI. Receiver operating characteristic (ROC) analysis was performed to identify a BMI cut-off point associated with high risk OSA. Results 321 men were analyzed. Median age was 64 (56, 69) years. Median SB score was 4 (3, 5), 55% were high risk, 25% moderate risk, and 19% low risk. 46% had 2 ≥ comorbidities. 57% had T levels ≤300 ng/dL. Median total and free T were 281 (222, 373) and 7.5 (5.4, 10) ng/dL and median LH was 3.7 (2.2, 6.7). Median HCT was 44% (41, 46). 33% had HCT ≥ 45%, and 4% had HCT &amp;gt; 50%. Median BMI was 29 (26, 33) kg/m2 and 42% had obesity (BMI ≥ 30 kg/m2). On MVA, BMI and ≥2 comorbidities predicted high risk for OSA. ROC analysis showed cut-off point BMI ≥ 27 kg/m2 is associated with high risk for OSA by SB (sensitivity=0.8; specificity=0.6; AUC=0.77; p&amp;lt;0.001). For men with BMI ≥27 kg/m2, the rate of high risk OSA was 71%, versus 29% rate of high risk in men with BMI &amp;lt;27 kg/m2. Conclusions BMI ≥ 27 kg/m2 or higher and the presence of 2 or more comorbidities are the main predictors of high risk OSA. Disclosure No.

Prevalence of obstructive sleep apnea among Southern Indian pregnant women attending antenatal care

Background: Physiological and hormonal changes during pregnancy can alter the sleep patterns of the pregnant women and were said to be precursor for the development of obstructive sleep apnea (OSA) and complication of pre-existing OSA. Developing country like India has no health cost distribution for the treatment, as this condition’s treatment trends absorbs 65–82% of all health cost. There is oblivious state among clinicians and patients, self-reporting of the symptoms are poor which, in turn, results to upshot underdiagnoses of OSA among southern Indian population. Aims and Objectives: The aim of the study is to screen the prevalence of OSA among the southern Indian pregnant women attending antenatal care and to evaluate its predisposing factors. Materials and Methods: We enrolled 305 pregnant women according to our study selection criteria, attended antenatal care at ACS medical college and hospitals from Chennai. On face-to-face basis, berlin questionnaire screening was done. With a brief interview, sociodemographic details, medical records and laboratory parameters were obtained. To cluster the risk of OSA prevalence, percentage was estimated using frequency distribution. Chi-square analysis was done to obtain significant relationship between contributing factors and OSA symptoms. Statistical testing was done with SPSS software version 21. Results: Among 305 pregnant women, 31.8% (97) were shown to have high-risk OSA and 68.2% (208) low-risk OSA. Across the trimester, high-risk OSA were noted among 8.2% (25), 11.1% (34), and 15.4% (48) at first, second, and third trimester, respectively. Age, body mass index, occupation, neck circumference, multiple pregnancy, and presence of conditions such as gestational hypertension, chronic hypertension, adenoids, mallampatti grade, nasal congestion, and family history of OSA can be the predisposing factors which could influence the OSA symptoms. Conclusion: The future investigations should rely on the analysis of the fetal outcomes after proper diagnosis of OSA. Furthermore, independent predictive values of physical signs, history, risk factors, and mechanisms behind the progression of OSA should be studied well. Region and area specific difference of risk of OSA to identify disparities and to promote decentralization of sleep care could be done.
