Quality of life, sleep and anxiety status among patients with rosacea in the Yunnan plateau region: A 2-year retrospective study.

To investigate the life, sleep quality and anxiety of rosacea patients in Yunnan and the improvement of these aspects after treatment. A total of 141 patients with rosacea and 123 healthy controls were included in our study. The quality of life, sleep quality and anxiety of patients with rosacea and healthy controls were investigated by the Rosacea Severity Scores (RSSs), the Medical Outcomes Study 36-item short-form health survey (SF-36), the Pittsburgh Sleep Quality Index (PSQI) and Self-rating Anxiety Scale (SAS). The quality of life, sleep quality and anxiety of patients with rosacea were assessed again after treatment. Compared with healthy controls, patients with rosacea had significantly lower physical component scores (PCS) and mental component scores (MCS) but higher PSQI and SAS scores. After treatment, rosacea patients showed significantly higher MCS but lower PSQI and SAS scores. Correlation analysis showed a significant correlation between PCS, MCS, PSQI, SAS and RSSs. Patients with rosacea have a lower quality of life and sleep quality and tend to be more anxious than healthy controls. In addition, the mental quality of life, sleep quality and anxiety of rosacea patients can be significantly improved after treatment. Therefore, it is important to pay attention to the psychological status of rosacea patients. Psychological counseling and intervention are necessary to better prevent and treat rosacea.

Impact of Natural Chinese Medicine Acupoint Application on Anxiety in Long-Term Hemodialysis Patients and Analysis of the Corresponding Nursing Measures

This study aimed to determine the effects of natural herbal acupoint application on anxiety in long-term hemodialysis patients and analyze the corresponding nursing measures. Between March 2020 and January 2022, 150 long-term hemodialysis patients admitted to our hospital were surveyed for this study. A questionnaire survey was conducted to determine the anxiety status of the patients. Patients with anxiety were registered and randomly divided into a research group and a control group. The control group received traditional routine nursing care, while the research group received personalized interventional nursing care combined with natural herbal acupoint application. The comfort level, sleep quality, emotional management ability, and negative emotional status before and after the intervention were compared between the two groups. The 58 (38.66%) patients who experienced anxiety were divided into control and research groups, with 29 patients per group. No significant differences in baseline characteristics were detected between the two groups (P >0.05). The research group had significantly higher General Comfort Questionnaire (GCQ) scores and significantly lower Pittsburgh Sleep Quality Index (PSQI) scores compared with the scores in the control group (P <0.05 for both). The research group had higher scores in emotional processing, interpersonal relationships, and psychological activity management than the control group, indicating better emotional management ability (P <0.05). Moreover, the research group had significantly lower scores on the Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) than the control group (P <0.05). In this study, targeted interventions combining individualized nursing care and traditional Chinese medicine acupoint patching were administered to patients, which effectively promoted their physical and mental well-being, enhanced patient comfort, improved sleep quality, and effectively managed patient anxiety, as well as alleviated negative emotions. Therefore, natural herbal patches are worthy of promotion and application in clinical settings.

Sweet dreams are not made of this: no association between diet and sleep quality.

Numerous studies have emphasized the significance of nutrition on the quality of sleep, but few have evaluated the effect of various coexisting dietary markers on middle-aged adults. We assessed the association between sleep quality and a large array of dietary markers among middle-aged, community-dwelling participants. Data from the first, second, and third follow-ups of CoLaus|PsyCoLaus, a population-based study in Lausanne, Switzerland, was used. Sleep quality was assessed by the Pittsburgh Sleep Quality Index. Dietary intake was assessed by a validated food frequency questionnaire. Data from 3857 (53% women, 57.2 ± 10.4 years), 2370 (52% women, 60.7 ± 9.5 years), and 1617 (52% women, 63.5 ± 9.0 years) participants from the first, second, and third follow-ups was used. Bivariate correlations showed fish, vegetables, fruit, and cheese intake to be associated with a better sleep quality (lower Pittsburgh Sleep Quality Index), while rusks, sugar, and meat intake were associated with a poorer sleep quality (higher Pittsburgh Sleep Quality Index). After multivariable adjustment, participants reporting poor sleep quality (Pittsburgh Sleep Quality Index > 5) had a lower Mediterranean diet score and a lower likelihood of complying with the meat and fish recommendations, but the results were inconsistent between surveys. No association was found between sleep quality and macro- or micronutrients in the three surveys. No consistent associations were found between a large panel of nutritional markers and sleep quality. Components of the Mediterranean diet such as dairy, fruits, and vegetables might favor good sleep quality, while increased consumption of sugary foods or meat might favor poor sleep quality.

Study on the effect of internet plus continuous nursing on functional recovery and medication compliance of patients with knee joint replacement

ObjectiveTo evaluate the effect of "Internet + " continuity of care on postoperative functional recovery and medication compliance in patients with knee arthroplasty.MethodsIn this retrospective study, 100 patients who underwent knee replacement in our hospital between January 2021 and December 2022 were recruited and assigned to receive routine care (routine group) or "Internet + " continuity of care (continuity group), with 50 patients in each group. Outcome measures included knee function, sleep quality, emotional state, medication compliance, and self-care ability.ResultsPatients in the continuity group showed better knee function after discharge and during follow-up versus those in the routine group (P < 0.05). Continuity care resulted in significantly lower Pittsburgh Sleep Quality Index (PSQI), Self-Rating Anxiety Scale (SAS), and Self-Rating Depression Scale (SDS) scores versus routine care (P < 0.05). Patients in the continuity group showed higher treatment compliance, ability of daily living (ADL) scores, and nursing satisfaction than those in the routine group (P < 0.05).ConclusionThe "Internet + " continuity of care is highly feasible and can effectively promote the postoperative functional recovery of knee replacement patients, improve patients' medication compliance, sleep quality, and self-care ability, mitigate negative emotions, and provide enhanced home care.

Effect of Fennel-Valerian Extract on Hot Flashes and Sleep Disorders in Postmenopausal Women: A Randomized Trial.

This study aims to evaluate the effect of a mixture of fennel and valerian extracts on hot flashes and sleep disorders of postmenopausal women in Iran. A randomized trial was conducted. A total of 76 postmenopausal women were randomly assigned to either of the two groups: fennel-valerian extract or control. One 500 mg fennel-valerian extract capsule was given twice, daily for 8 weeks. The 500 mg oral placebo capsule (starch) was given the same way. The mean duration of hot flashes increased in both the groups over time (P < 0.001). The mean frequency and severity of hot flashes in the intervention group were significantly lower than in the control group, in the first and second months after intervention (P < 0.050). Women in the fennel-valerian extract group had a significantly lower Pittsburgh Sleep Quality Index score than the control group 2 months after intervention (P = 0.030). This study found that fennel-valerian extract was effective for relieving sleep disorders as well as the severity and frequency of hot flashes compared with a placebo.

Observation on the Efficacy of Moxibustion Combined with Ear Acupoint Pressing Beans in Treating Patients with Phlegm Stasis Syndrome Vertigo.

Objective The aim of this study is to investigate the efficacy of moxibustion combined with an ear acupoint pressing bean in the treatment of patients with phlegm stasis syndrome vertigo. Methods 60 patients with vertigo identified as phlegm stasis syndrome who were hospitalized in our department from May 2020 to May 2021 were selected and divided into a control group and a treatment group of 30 cases each according to the random number method. The control group was treated with conventional treatment and care, and the treatment group was treated with moxibustion combined with ear acupressing beans on top of the conventional group. The treatment effects, the dizziness disorder inventory (DHI), Pittsburgh sleep quality index (PSQI), Hamilton anxiety score (HAMA), TCM symptom score, and blood flow parameters (left vertebral artery flow velocity (LVA), right vertebral artery flow velocity (RVA), and basilar artery flow velocity (BA)) of the two groups were compared with each other during and after the treatment. Results After implementation, the treatment efficiency of the treatment group was higher than that of the control group, and the treatment group had lower PSQI, HAMA, and DHI scores as well as TCM symptom scores such as vertigo, head heavy as a wrap, chest tightness, and nausea and vomiting than the control group (P < 0.05). In addition, LVA, RVA, and BA were all higher in the treatment group than in the control group after treatment (P < 0.05). Conclusion Moxibustion combined with ear acupoint pressing bean treatment can clearly improve patients' sleep quality, psychological state, relieve patients' various symptoms caused by vertigo, improve blood flow parameters, and have better efficacy in the treatment of phlegm stasis syndrome vertigo.

Effect of Conventional Nursing Combined with Bedtime Oculomotor Training on Sleep Quality and Body Immunity of Advanced Lung Cancer Patients

Objective The aim of this study is to explore the effect of conventional nursing combined with bedtime oculomotor training on sleep quality and body immune of advanced lung cancer patients. Methods By means of a retrospective study, 120 advanced lung cancer patients admitted to our hospital from January 2019 to January 2020 were selected as the research subject and divided into the intervention group (PSQI (Pittsburgh Sleep Quality Index) score≥10 points, n = 60) and the control group (PSQI score<10 points, n = 60). Conventional nursing was performed to the control group, and an eye movement exercise before sleep was added additionally in the intervention group, 30 min each time, once a day, and 5 times a week for 3 months, so as to compare their sleep quality, body immunity indexes, negative emotion scores, adverse reaction rate (ARR), quality of life, and satisfaction with nursing. Results After nursing, the intervention group obtained a significantly lower PSQI score (5.54 ± 1.23 VS 7.98 ± 1.65, P < 0.05), better body immunity indexes (P < 0.001), lower negative emotion scores (P < 0.05), lower ARR (P < 0.05), better quality of life (P < 0.001), and higher satisfaction with nursing (P < 0.05) than the control group. Conclusion Combining conventional nursing with the eye movement exercise before sleep can alleviate negative emotions, improve the sleep quality, promote body immunity, and reduce the ARR, which is more satisfying to patients and should be applied and promoted in practice.

Using 24-h Heart Rate Variability to Investigate the Sleep Quality and Depression Symptoms of Medical Students.

There have been numerous studies on the relationship between sleep and depression, as well as the relationship between sleep and depression, and heart rate variability (HRV), respectively. Even so, few studies have combined 24-h HRV analysis to study sleep quality and depressive symptoms. The purpose of this cross-sectional study was to investigate the relationship between depressed symptoms, sleep quality, and 24-h HRV in medical students. The particiants were all students at a medical university in Guangdong province, China. A total of 74 college students participated. They were asked to complete a questionnaire that included the Pittsburgh Sleep Quality Index (PSQI), the Beck Depression Inventory-II (BDI-II), the Positive and Negative Affect Scale (PANAS), and 24-h ECG monitoring. The results showed that 41.7% of the medical students had poor sleep quality, with higher levels of depressive symptoms and more negative emotions, and there was no difference in 24-h HRV indices between the low PSQI group and the high one. Correlation analysis showed that there was a significant relationship between sleep quality and depressive symptoms (r = 0.617), but the relationship between 24-h HRV indices and PSQI global scores, BDI scores were not significant. However, the correlation analysis of PSQI components and 24-h HRV showed that sleep disturbance was significantly negatively correlated with SDNN and LF in waking period (r = −0.285, −0.235), and with SDNN in sleeping period (r = −0.317). In general, the sleep disturbance in PSQI components can sensitively reflect the relationship between sleep quality and 24-h HRV of medical students. Individuals with higher sleep disturance may have lower SDNN during awake period and bedtime period, and lower LF in awake period. Twenty-four hour HRV has certain application value in clinical sleep quality monitoring, and its sensitivity and specificity in clinical application and daily life are still worth further investigation.

322 Comparisons of clinical and polysomnographic characteristics between negative and positive sleep state misperception in insomnia

Abstract Introduction Most of insomnia patients tend to underestimate their sleep duration and quality. In current study, we classified insomnia patients into negative sleep state misperception (NSSM) group and positive sleep state misperception (PSSM) group according to difference between subjective and objective sleep duration. We compared clinical and polysomnographic characteristics between two groups. Methods Objective sleep measures using nocturnal polysomnography (nPSG) and subjective measures including Pittsburgh Sleep Quality Index (PSQI), Beck Depression Inventory (BDI) and subjective questionnaire at the morning after overnight nPSG of 150 insomnia patients were reviewed. The questionnaire included subjective total sleep time (subjective TST), subjective sleep latency (subjective SL). Additionally, TST/SL discrepancy was calculated by subtracting objective variables of nPSG from the morning subjective questionnaire. We calculated misperception index (MI) using the following method; MI=(objective TST-subjective TST)/objective TST. According to MI value, insomnia patients were classified into NSSM (MI&amp;gt;0, n=115), and PSSM (MI&amp;lt;0, n=35) groups. Results There were no significant differences in nPSG parameters, except N3 sleep (%); the PSSM group had significantly higher N3 sleep than NSSM group (p=0.002). On the subjective measures, the NSSM group had significantly higher PSQI score (p&amp;lt;0.001), longer subjective SL (p=0.001) and higher SL discrepancy (p=0.001). In the NSSM group, MI showed positive correlations with N1 sleep proportion (r=0.250, p=0.011), PSQI (r=0.250, p=0.011), BDI (r=0.211, p=0.032), subjective SL (r=0.441, p&amp;lt;0.001) and SL discrepancy (r=0.453, p&amp;lt;0.001). Meanwhile, there were no significant correlations of MI with subjective measures in PSSM group. In the multiple regression analysis, MI was related with SL discrepancy and BDI (R2=0.216, p=0.004) in NSSM group. For belonging the PSSM group, associated factors were N3 sleep (OR=1.075, p=0.001), PSQI (OR=0.813, p=0.002) and SL discrepancy (OR=0.956, p&amp;lt;0.001) on binary logistic regression analysis. Conclusion In the NSSM group, MI was related with high SL discrepancy and depressive mood. High N3 sleep, low PSQI score, and low SL discrepancy were associated factors in the PSSM group. Perception of sleep should be properly evaluated and managed, since they vary with different characteristics of sleep state misperception.

Ablative fractional CO2 laser surgery improving sleep quality, pain and pruritus in adult hypertrophic scar patients: a prospective cohort study.

BackgroundPoor sleep quality is associated with a decrease in quality of life in patients with major burn scars, combined with pruritus and pain. Few interventions have been reported to improve the sleep quality of patients with scars. In the current prospective cohort study, we investigated the efficacy of CO2-ablative fractional laser (AFL) surgery vs conventional surgery in post-burn patients with hypertrophic scars with sleep quality as the primary study outcome.MethodsIn total 68 consecutive patients undergoing scar surgical treatment were recruited, including a CO2-AFL surgery cohort (n = 35) and a conventional surgery cohort (n = 33). A subgroup from the AFL cohort was selected. Sleep quality, pain and pruritus were evaluated. Multiple linear regression analyses were performed to reveal the effect of CO2-AFL surgery.ResultsThe CO2-AFL surgery cohort had significantly lower Pittsburgh sleep quality index (PSQI) global scores than the conventional surgery cohort after the last surgical treatment. In the subgroup of patients receiving hardware sleep monitoring, CO2-AFL markedly increased deep sleep time, deep sleep efficiency and reduced initial sleep latency. Compared to the conventional surgery cohort, the CO2-AFL cohort presented significantly lower pain and pruritus scores. Correlation analysis showed pain and pruritus were significantly associated with PSQI scores, and there were also significant correlations between pain and pruritus scores. Multiple linear regression analysis showed that surgery method was negatively linearly correlated with visual analog scale (VAS) pain score, brief pain inventory (BPI) total, VAS pruritus score, 5-D itch scale total, four-item itch questionnaire (FIIQ) total and PSQI total.ConclusionsCO2-AFL surgery significantly improved sleep quality and reduced pain and pruritus of hypertrophic scar patients. The alleviation of sleep disorder was associated with improvement of deep sleep quality including deep sleep time and deep sleep deficiency.Trial registrationThe Chinese Clinical Trial Registry (ChiCTR200035268) approved retrospectively registration on 5 Aug 2020.

Music on Prescription to Aid Sleep Quality: A Literature Review.

Research on the efficacy of music for improving sleep quality has produced mixed results. We investigated whether the number of music dosages could be a reason for the lack of clarity. Six longitudinal music sleep studies using the Pittsburgh Sleep Quality Index (PSQI) over 3 weeks were identified. Music when compared to active (audiobooks or medication) or passive controls significantly improved (improvement is reflected by a lower score) PSQI within the first or second week of prescription. The improvement was an average mean difference of −1.15 (SD = 0.53) for each week. Music dosages continued to be associated with improved PSQI over a study that had a 3-month music intervention. One study with a low initial PSQI score resulted in poor sleepers (PSQI > 5) achieving healthy sleep (PSQI < 5) within 3 weeks of regular music intervention. For future studies, “prescribing” music beyond 3 weeks may lead to more instances of healthy sleep, particularly for those who have mild sleep problems. To explain the findings, we proposed that the relationship between weeks of music listening and improved PSQI are attributed to the truncation of poor bedtime habits linked to ruminative tendencies and consequent hyperarousal prior to the music intervention. Music listening at bedtime replaces those bad habits, we argue, by forming a new psychological link between bedtime and sleep through evaluative conditioning. The findings of the present study provide disarming evidence of the potential for prescription of music for treating mild sleep disorder.

979-P: Improved Technology Satisfaction and Sleep Quality with Medtronic Minimed Advanced Hybrid Closed-Loop Delivery Compared with Predictive Low Glucose Suspend in People with Type 1 Diabetes in a Randomized Crossover Trial

Background: Automated insulin delivery aims to lower treatment burden and improve quality of life as well as glycemic outcomes. Methods: This dual-centre, randomized, open-label, two-sequence cross-over study in automated insulin delivery naïve users, compared Medtronic Minimed® Advanced Hybrid Closed Loop (AHCL) to Sensor Augmented Pump therapy with Predictive Low Glucose Management (SAP+PLGM). At the end of each 4 week intervention impacts on quality of life were compared using age-appropriate scales: Diabetes Treatment Satisfaction Questionnaire status and change (DTSQs and DTSQc), Diabetes Technology Questionnaire (DTQ), Pittsburgh Sleep Quality Index (PSQI), World Health Organisation-Five Well-Being Index (WHO-5), Hypoglycemic Fear Survey (HFS-II) and Hypoglycemia Confidence Scale (HCS). Results: 59/60 people completed the study (mean age 23.3±14.4yrs). Statistically significant differences favouring AHCL were demonstrated in several scales (data shown as mean±SE). Technology satisfaction favoured AHCL over PLGM as shown by a higher score in the DTSQs during AHCL (n=28) vs. SAP+PLGM (n=29) (30.9±0.7 vs. 27.9±0.7, p=0.004) and DTSQc AHCL (n=29) vs. SAP+PLGM (n=30) (11.7±0.9 vs. 9.2±0.8, p=0.032) in adults. Adolescents also showed a higher DTSQc score during AHCL (n=16) vs. SAP+PLGM (n=15) (14.8±0.7 vs. 12.1±0.8, p=0.024). The DTQ “change” score (n=59) favoured AHCL over SAP+ PLGM (3.5±0.0 vs. 3.3±0.0, p&amp;lt;0.001). Improved sleep quality was demonstrated by the lower PSQI in those aged over 16 years (n= 36) during AHCL vs. SAP+PLGM (4.8±0.3 vs. 5.7±0.3, p=0.048) with &amp;gt; 5 indicating poor quality sleep. No differences were found in the other scales. Conclusion: The findings from this RCT suggest AHCL compared to SAP + PLGM mode has the potential to increase treatment satisfaction and improve subjective sleep quality in adolescents and adults with T1D.

0495 Auricular Acupuncture Treatment Associated with Improved Self-Reported Sleep and Emotional Distress in Hispanic and Latino Immigrants: A Preliminary Report

Abstract Introduction Hispanic and Latino immigrants face sociocultural stressors that may contribute to sleep disturbance. We investigated: 1. Whether Hispanic/ Latino immigrants with self-reported sleep disturbance showed improvements in sleep with auricular acupuncture; 2. If sleep effects were associated with emotional distress. Methods Emotional distress and sleep responses to auriculotherapy in Hispanic/ Latino adult immigrants were measured using Emotional Distress (ED), Athens Insomnia (AI), and Pittsburgh Sleep Quality Index (PSQI) scales completed Baseline, Mid (4 treatments), and Follow-up (8 treatments). Randomly assigned intervention was bi-weekly for 8 treatment sessions of 5 needles inserted bilaterally: Active Intervention [NADA protocol (Shen men, sympathetic autonomic, lung, liver and kidney points)] OR Sham Control (outer ear helix with no active points). Scores were compared between Groups (NADA or SHAM) and within (Pre-, Mid- and Post-treatment) sessions using Mixed-Model ANOVA; multiple linear regression assessed ED scores association with sleep. Results Ten Hispanic/ Latino female participants [NADA, N=5, mean (SD) age = 41 (14); SHAM, N =5; mean (SD) age = 42 (17)]. Anovas for the ASI, PSQI, and ED showed significant within-subjects effects (p’s &amp;lt; .05). Baseline; Mid; Follow-up Mean (SD) = AIS: 12.3 (8.9); 8.5 (6.9); 7.1 (12.8); PSQI: 10.9 (5.4); 8.9 (2.8); 7.6 (3.4); ED: 25.6 (50.4); 17.6 (26.7); 16.9 (29.8). Post-hoc t-tests were significant between Baseline/ Mid and Baseline/ Final for all measures (p’s &amp;lt; .05). Linear Regression showed significant association between ED and PSQI (R square = 0.25; p &amp;lt; .05): lower Emotional Distress associated with lower PSQI. Conclusion Auriculotherapy may improve sleep in Hispanic/ Latino immigrants after 4 treatments suggesting a novel, low-cost, easily implemented group treatment option for improving sleep in this community. Better sleep was associated with decreases in emotional distress supporting our hypothesis. Data collection continues and larger sample size will allow for increased power to detect between group differences.

0848 The Relationship Between Sleep Disturbance &amp; Sleep Hygiene In Japanese Pregnant Women

Abstract Introduction Pregnant women are more likely to develop sleep disorders due to poor sleep quality. Sleep hygiene has been reported as a method for dealing with sleep disorders. However, studies on the relationship between sleep hygiene and sleep disorders in Japanese pregnant women remain insufficient. This study aimed to clarify the actual state of sleep disorders during pregnancy and the relationship between sleep disorders and sleep hygiene. Methods A cross-sectional study was conducted on 147 Japanese pregnant women. We used the Japanese versions of the Pittsburgh Sleep Quality Index (PSQI) and the Epworth Sleepiness Scale (JESS) for evaluation of sleep. We used 32 items of habitual behavior important for sleep improvement for evaluation of sleep hygiene; these items were self-selected. Results The average PSQIG scores of women in their first, second, and third trimesters were 5.6 ± 4.3, 5.4 ± 2.4, and 6.6 ± 2.8, respectively; 22.2%, 46.4%, and 62.2% of women in their first, second, and third trimesters, respectively, exceeded the cut-off score. The average JESS scores were 12.2 ± 4.5, 9.9 ± 4.1, and 10.0 ± 4.6 for first, second, and third trimester women, respectively; 55.6%, 35.7%, and 41.9% of first, second, and third trimester women, respectively, slept excessively during the day (JESS score≥11). Following factor analysis, sleep hygiene was categorized into four factors: ”thinking positively,” ”adding rhythm to the day,” “avoiding going out and caffeine before bedtime,” and “avoiding eye irritation.” Pregnant women who “added rhythm to their day” had lower PSQI scores, and sleep hygiene was not related to JESS scores in the multiple regression analysis of sleep hygiene and sleep disorders. Conclusion Sleep disorders in pregnancy are related to habitual behavior such as being active during the day, eating and sleeping regularly, and basking in the sunlight every morning. Support

Abstract MP20: Evening Chronotype is Associated With Poor Cardiovascular Health and Adverse Health Behaviors in a Diverse Population of Women

Background: Chronotype is the behavioral manifestation of an individual’s innate circadian rhythm. Evening chronotype (i.e. being a “night owl”) is linked to elevated chronic disease and mortality risk in European and Asian populations. Evidence from US cohorts is limited, particularly among women, in whom evening chronotype prevalence becomes higher from midlife onward, coinciding with life stages and hormonal changes associated with higher cardiovascular disease (CVD) risk. Hypothesis: Being a definite evening chronotype would be associated with poor cardiovascular health (CVH) and elevated cardiometabolic risk factors. Methods: Participants were 506 diverse women (mean age=37±16y, 62% racial/ethnic minority) in the AHA Go Red for Women Strategically Focused Research Network at Columbia University. Chronotype was measured using the Morningness-Eveningness Questionnaire (MEQ), the most widely used validated tool by circadian biologists to ascertain chronotype. Higher scores reflected greater morningness. Participants were also categorized as “evening” vs. “intermediate/morning” chronotypes based on their MEQ scores. Health behaviors (diet, physical activity, sleep, and sedentary time) were assessed using validated questionnaires. Health factors (BMI, blood pressure, fasting glucose, and cholesterol) were assessed at the clinic visit. Overall CVH was evaluated using the AHA Life’s Simple 7 (LS7) score (0-8: poor, 9-14: moderate to high). Linear and logistic regression models adjusted for age, race/ethnicity, education, health insurance, and menopause were used to examine associations of chronotype with CVH, clinical risk factors, and health behaviors. Results: Overall, 13% of women identified as being evening chronotypes. Higher MEQ scores (i.e. greater morningness) were associated with higher AHA LS7 scores (β=0.02, p=0.01), indicative of more favorable CVH. Higher MEQ scores were also associated with having a lower Pittsburgh Sleep Quality Index, i.e. better sleep quality, (β=-0.07, p&lt;0.0001), a lower Insomnia Severity Index (β=-0.14, p&lt;0.0001), shorter time to fall asleep (β=-0.28, p=0.04), and less sedentary time (β=-0.11, p=0.001). In contrast, being an evening chronotype was associated with higher odds of poor CVH (OR (95%CI): 2.41 (1.20-4.85)), not meeting AHA diet (OR (95%CI): 2.89 (1.59-5.23)) and physical activity guidelines, (OR (95%CI): 1.78 (1.03-3.07)), and having short sleep (&lt;7h) (OR (95%CI): 2.15 (1.24-3.73)) or insomnia symptoms (OR (95%CI): 2.69 (1.53-4.75)). Conclusions: Women with evening chronotypes have greater odds of having poor CVH and adverse health behaviors after adjustment for sociodemographic factors and menopausal status. Chronotype may be important to consider and target in lifestyle interventions aimed at CVD prevention, particularly among middle-aged and older women who are prone to sleep changes.

The association between sleep quality and the degree of coronary atherosclerotic stenosis

Objective To explore the correlation between sleep and the severity of coronary artery stenosis, and to further guide the prevention and control of coronary heart disease. Methods A total of 302 patients, including 183 males and 119 females, were enrolled in the department of cardiology of Changhai hospital from February to June 2019. The patients were divided into three groups according to the degree of stenosis (atherosclerotic group, atherosclerotic group with degree of stenosis 70%). General information, comorbidities and Pittsburgh sleep quality index (PSQI) of patients in each group were analyzed to compare the differences and analyze the risk factors of aggravated coronary artery stenosis. Results There were statistically significant differences in age, gender and diabetes among all groups (P 0.05). Spearman correlation analysis showed that PSQI score was positively correlated with the degree of atherosclerosis (P<0.01). In the multivariate regression model, poorer sleep quality (OR=1.75, 95% CI: 1.14-2.69, P<0.05), shorter sleep time (OR=1.64, 95% CI: 1.05-2.55, P<0.05) and more diurnal dysfunction (OR=1.45, 95% CI: 1.11-1.88, P<0.01) were correlated with increased coronary artery stenosis. Higher PSQI total score (OR=1.13, 95% CI: 1.06-1.20, P<0.01) and lower PSQI evaluation grade (very bad vs very good: 13.85, 95% CI: 1.56-122.82, P<0.05) were also related to the increase of coronary artery stenosis. Conclusions Poorer sleep quality, shorter sleep time and more diurnal dysfunction were independent risk factors for the aggravation of coronary artery stenosis. Higher Pittsburgh sleep quality index was significantly associated with the severity of coronary artery stenosis. Key words: Sleep; Coronary artery disease; Atherosclerosis; Coronary stenosis

Effects of aromatherapy on improving perioperative anxiety and sleep in patients with gastric cancer

Objective To evaluate the effects of aromatherapy on improving perioperative anxiety and sleep in patients with gastric cancer. Methods A total of 120 patients undergoing gastrectomy from December 2016 to July 2017 in the First Affiliated Hospital of Wenzhou Medical University were selected in the study using convenient sampling. The participants were randomly divided into the intervention group (n=60) and the control group (n=60) . Based on the routine nursing care, the intervention group received additional geranium aromatherapy from 9 pm to 6 am at one day before the surgery. The Self-Rating Anxiety Scale (SAS) and Pittsburgh Sleep Quality Index (PSQI) were used to evaluate the anxiety and sleep quality. The blood pressure (BP) and heart rate (HR) were compared before and after the intervention. Results The repeated ANOVA showed that BP, HR and the SAS points had time and groups interactions at one day before the surgery, one hour before the surgery and one day after the surgery. There were no statistically significant differences in PSQI at one day before the surgery between two groups (P>0.05) . But after the aromatherapy, the intervention group had significantly lower PSQI than before operation, and lower than the control group (P<0.01) . Conclusions The aromatherapy can effectively alleviate anxiety, improve sleep quality and stabilize BP and HR in patients with gastrectomy.

The aim of this study was to compare the sleep quality, depression, anxiety, and autonomic function of a group of kidney-transplanted recipients who joined a combined exercise program (KTRt) or remained sedentary (KTRs). A total of 20 kidney-transplanted recipients, split into two groups (10 KTRt and 10 KTRs), joined the study. Heart rate variability, cardiorespiratory capacity, depression, and sleep questionnaires were evaluated. KTRt presented lower Pittsburgh Sleep Quality Index and greater entropy, and increased parasympathetic and decreased sympathetic modulation than KTRs. Anxiety level was minimal and depression was absent in both groups. KTRt group presented better sleep quality and better autonomic modulation than KTRs.

Dietary fish intake and sleep quality: a population-based study

Background/ObjectivesDue to the content of omega-3 and vitamin D, fish consumption is likely to be associated with better sleep. However, current data are limited to a single study that is not representative of the population at large. The present study aimed to assess the effects of oily fish consumption on sleep quality in community dwelling adults living in rural coastal Ecuador. MethodsAtahualpa residents aged ≥40 years and who were identified during a door-to-door survey were interviewed with field instruments directed at assessing cardiovascular risk factors, sleep quality, and fish consumption. Using parametric regression and generalized linear models adjusted for demographics and cardiovascular risk factors, the study evaluated whether oily fish consumption is associated with a lower Pittsburgh sleep quality index (PSQI). ResultsOut of 721 eligible people, 677 (94%) were enrolled. Mean oily fish consumption was 9 ± 6 servings per week (one serving = 140 grams). Poor sleep quality was noticed in 187 (28%) individuals. Oily fish intake was higher in individuals with good sleep quality (p = 0.013). There was an inverse association between the PSQI score and oily fish servings per week in both parametric regression (β = −0.040; 95% CI −0.690 to −0.011, p = 0.007) and the adjusted generalized linear model (β = −0.032; 95% CI −0.605 to −0.004, p = 0.025). ConclusionsOily fish consumption is associated with better sleep quality. Even in people who ingest more than the recommended amount of fish, an increase in fish intake is associated with further improvement in the quality of sleep.

A survey on sleep quality and personality of staffs suffering long-term chronic stress

Objective To investigate the sleep quality and personality of staffs suffering long-term chronic stress. Methods A total of 100staffs working in a showcase unit in Shanghai for over 1year(with long-term chronic stress)were assessed with Pittsburgh sleep quality index(PSQI),Eysenck personality questionnaire(EPQ)and self-rating symptom scale(SCL-90).The sleep quality and mental health status were compared between staffs with different personalities. Results Totally 97valid questionnaires were collected and the valid response rate was 97%.(1)Under long-term chronic stress the mean score of PSQI was(2.76±1.85)for the 97staffs,and 18.6%(18/97)of them had sleeping disorders(PSQI ≥5).Staffs of different genders,ages,educational backgrounds and seniorities showed no significant difference in sleeping disorder incidence(P0.05).(2)The psychoticism and neuroticism scores of EPQ in the 97staffs were significantly lower than the norms,while their extraversion-introversion dimension of EPQ was significantly higher than the norms(P0.05).(3)The emotion stable staffs(66)had significantly lower PSQI and SCL-90scores compared with the intermediate staffs(31, P0.05);the extravert staffs(72)also had significantly lower PSQI and SCL-90scores compared with the intermediate staffs(25,P0.05).(4)Compared with the norms,the total scores and the scores of somatization,obsessive-compulsive, interpersonal relationship,depression,anxiety,hostility,phobic anxiety,and paranoid ideation of SCL-90were significantly lower in staffs under long-term chronic stress(P0.05).(5)It showed that the score of extraversion-introversion dimension of EPQ was negatively correlated with the scores of obsessive-compulsive,interpersonal relationship,depression, anxiety,phobic anxiety,paranoid ideation and psychoticism factors of SCL-90,while the neuroticism score of EPQ was positively correlated with all factors of SCL-90(P0.05).Conclusion The prevalence of sleep disorder of staffs under the long-term chronic stress is 18.6%in our study.The personality of staffs under the long-term chronic stress is extravert and emotionally stable.Staffs with extravert personality and stable type are less likely to have psychological and sleep quality problems.
