Factors associated with the fragmentation and stability of the rest-activity rhythm in adults and older adults.

This cross-sectional study aimed to identify factors related to the fragmentation and stability of the rest-activity rhythm (RAR) in adults and older adults. It is part of a larger research project investigating aspects concerning sleep duration, quality, and disorders in a representative subsample of the population. Sociodemographic data, lifestyle, health habits and subjective sleep variables were obtained; RAR records were collected by means of actigraphy and analyzed using non-parametric variables (IS, IV, M10, L5, RA, sL5, and sM10). Study participants were 313 individuals with complete actigraphy records. There was a prevalence of older adults (50.2%) and females (51.1%). Females, individuals with 4-8 y of education, and those who used alcohol abusively exhibited lower RAR fragmentation. Higher fragmentation was observed in individuals who napped and those reporting poor sleep quality. Greater rhythm stability was evident in females, older adults, those with 4-8 y of education, and those who had a partner. Smokers demonstrated lower RAR stability. These findings may contribute valuable insights for decision-making aimed at preventing and treating issues related to fragmentation and instability of the rhythm and its possible consequences to health.

Sleep in pregnancy quarters: a longitudinal study / El sueño en el trimestres gestacionales: un estudio longitudinal / O sono nos trimestres gestacionais: um estudo longitudinal

ABSTRACT Objective: To identify sleep characteristics and factors associated with sleep issues during pregnancy. Method: This is a longitudinal, with three follow-up periods at each gestational trimester (called T1, T2 and T3). Fifty (50) pregnant women without comorbidities started the study. The following instruments were used: sociodemographic and clinical characterization, Pittsburgh Sleep Quality Index and Sleep Diary. Data were analyzed using statistical tests (Chi-square, non-parametric tests and regression models). Results: We identified that 55.3% of the pregnant women reported sleep disorders in T1, 39.5% in T2, and 65.8% in T3; in T3, the risk of reporting sleep problems increased by 67% in comparison with T2. Conclusion: Considering the high prevalence of poor-quality sleep, especially in the third trimester, prenatal care is understood as a moment of intense learning and an opportunity for nurses to develop actions concerning education, guidance and sleep hygiene.

Depressive symptoms, symptoms of insomnia and stressful events in hypertensive older adults: Cross-sectional study.

OBJECTIVES: the aim of this study was to determine whether symptoms of insomnia and intensity of stressful life events are independently associated with depressive symptoms in community-dwelling hypertensive older adults. METHODS: this was an observational cross-sectional study. Participants were 438 older adults with arterial hypertension who completed questionnaires about depressive symptoms, stressful events, self-reported symptoms of insomnia and socio-demographic characteristics. Cluster analysis was performed to obtain groups according to insomnia symptoms. The following groups were identified: Poor Sleep Quality, Early Waking and Good Sleep Quality. Associations were tested using linear regression analysis and multiple Poisson regression analysis. RESULTS: The factors that independently contributed to the increase of depressive symptoms were belonging to the Poor Sleep Quality group (p<.001) and Early Waking group (p=.005), reporting higher intensity of stressful life events (p<.001) and having less schooling (p=.003). CONCLUSION: older adults with hypertension need a comprehensive approach to their health care that considers depressive symptoms and their relationship with intensity of stressful events, insomnia symptoms and schooling.

Sleep and Professional Burnout in Nurses, Nursing Technicians, and Nursing Assistants During the COVID-19 Pandemic.

BACKGROUND: The COVID-19 pandemic may trigger sleep disorders and burnout in nursing professionals. PURPOSE: This study was designed to describe the occurrence of sleep disorders and burnout in a nursing team during the COVID-19 pandemic and to identify the associated factors. METHODS: A cross-sectional approach was used. The questionnaire was administered via the Internet. All of the participants were nursing professionals who had provided care during the COVID-19 pandemic, and data were collected between June and August 2020. Sociodemographic and work characterization instruments, the Jenkins Sleep Scale, and the Maslach Burnout Inventory were used. RESULTS: Five hundred seventy-two nursing professionals (nurses, nursing technicians, and nursing assistants) responded. Slightly over one quarter (26.4%) presented a sleep disorder, and 17.3% presented burnout. Professional category was a factor found to be associated with having a sleep disorder. Moreover, a lower prevalence both of disorders and of starting to use sleep medication was found among nurses than nursing assistants. Moreover, an association was found between having a high level of emotional exhaustion burnout and being a nursing technician, having a higher number of patients needing care, and starting to use sleep medication. The level of burnout related to depersonalization was significantly higher for nursing assistants, those with a weekly workload of 50 hours or more, and those starting to use sleep medication. Furthermore, burnout related to personal accomplishment was significantly higher in those starting to use sleep medication. Among the participants with sleep disorders, according to Jenkins Sleep Scale results, all of the participants presented a high or moderate level of emotional exhaustion and a high level of burnout related to personal accomplishment. CONCLUSIONS/IMPLICATIONS FOR PRACTICE: The findings indicate that the incidence of sleep disorders and burnout were high among nursing professionals during the COVID-19 pandemic and mainly related with starting to use sleep medication. The results demonstrate the importance of detecting and assessing the frequency of sleep disorders and professional exhaustion. Interventions that aim to improve sleep quality and working conditions for these professionals should be developed.

Stressful events, depressive symptoms, and frailty associated to older adults' survival and mortality.

This study analyzed factors associated with survival and mortality risk of community-dwelling older adults, considering the intensity of stressful life events, depressive symptoms, insomnia, frailty, multimorbidity, and sociodemographic factors. This is a longitudinal study on survival of older adults interviewed between 2008-2009, with follow-up after 8 years. Survival and mortality risks were analyzed using the Kaplan-Meier curve, Log Rank test, and Cox proportional-hazards model (p < 0.05). Stressful events affecting older adults' children or grandchildren were associated with higher mortality risk; depressive symptoms and frailty were associated with lower survival. Comprehensive care for older adults must involve events regarding their family relationships, especially those affecting their progeny, due to the impact they can have on older adults' survival, besides evaluating depressive symptoms and frailty.

Síntomas depresivos, síntomas de insomnio y eventos estresantes en ancianos hipertensos: estudio de corte transversal / Depressive symptoms, symptoms of insomnia and stressful events in hypertensive older adults: Cross-sectional study

Objetivos: El objetivo de este estudio fue determinar si los síntomas de insomnio y la intensidad de los eventos de vida estresantes se asocian de forma independiente con los síntomas depresivos en ancianos hipertensos que viven en la comunidad. Métodos: Estudio de tipo observacional transversal. Los participantes fueron 438 ancianos con hipertensión arterial que completaron cuestionarios sobre síntomas depresivos, eventos estresantes, síntomas de insomnio y características sociodemográficas. Se realizó un análisis de conglomerados para obtener grupos según los síntomas de insomnio. Se identificaron los siguientes grupos: mala calidad del sueño, despertar temprano y buena calidad del sueño. Las asociaciones se probaron mediante un análisis de regresión lineal y un análisis de regresión de Poisson múltiple. Resultados: Los factores que contribuyeron de manera independiente al aumento de los síntomas depresivos fueron: pertenecer al grupo de mala calidad del sueño (p<0,001) y al grupo despertar temprano (p=0,005), reportando mayor intensidad de eventos de vida estresantes (p<0,001) y tener menos escolaridad (p=0,003). Conclusión: Las personas mayores con hipertensión arterial necesitan un abordaje integral de su atención en salud, considerando los síntomas depresivos y su relación con la intensidad de los eventos estresantes, los síntomas de insomnio y la escolaridad.(AU)

Is napping related with health-related behaviors and sleep habits among adolescents? A population-based study.

INTRODUCTION: Changes in sleep quality and quantity occur in adolescence and can lead to the compensatory behavior of daytime napping. OBJECTIVE: Analyze factors related to napping in adolescents. METHODS: A population-based cross-sectional study was conducted with 1022 adolescents who participated in the 2014-2015 Health Survey of the city of Campinas, state of São Paulo, Brazil. Napping was the dependent variable. Sociodemographic characteristics, living habits, health-related behaviors, feelings of loneliness, satisfaction with life and nocturnal sleep habits were the independent variables. Data analysis was performed using Rao-Scott chi-square test, unpaired Student's t-test and Poisson regression analysis; p < 0.05 was considered significant. The software STATA was used for analysis. RESULTS: Mean participant age was 14.6 years (SD: 2.7; range: 10 to 19 years). Males accounted for 50.9% of the sample and 55.7% had white skin color. A total of 40.5% reported napping. Napping was more common in females (p = 0.006), the 14-to-17-year-old age group (p = 0.002), those who took medications in the previous 15 days (p = 0.001), those who were insufficiently active (p = 0.036), those who reported little or no satisfaction with life (p = 0.008) and those who woke up in bad mood (p = 0.004). Adolescents who napped also reported shorter sleep during the week (p < 0.001) and a perceived greater need for sleep (p < 0.001). CONCLUSION: The prevalence of napping among the adolescents was independently associated with shorter average sleep, a perceived greater need for sleep than that obtained and waking up in a bad mood.

Is Sleep Quality Impaired and Is There Increased Risk of Obstructive Sleep Apnea Syndrome in Patients With Compensated Liver Cirrhosis?

As liver cirrhosis worsens, sleep pattern impairment and related complaints increase. The objective of this study was to identify the prevalence of poor sleep, excessive daytime sleepiness, and increased risk for obstructive sleep apnea syndrome in adults with Child-Pugh Class A liver cirrhosis; to investigate the association between poor sleep quality, daytime sleepiness, and risk for obstructive sleep apnea syndrome; and to verify the relationship between these 3 variables and clinical, laboratory, and sociodemographic data. A cross-sectional study was conducted with 100 individuals at the outpatient clinic of a university hospital in the interior of Sao Paulo, Brazil. Questionnaires were used in the form of interviews and consultation of medical records. There was a prevalence of 35.0% of poor sleep quality, 29.0% of excessive daytime sleepiness, and 38.0% of high risk for obstructive sleep apnea syndrome, as well as a significant association between high risk for obstructive sleep apnea syndrome and poor sleep quality. There was no significant association between laboratory variables and sleep quality, daytime sleepiness, and high risk for obstructive sleep apnea syndrome. There is a high prevalence of poor sleep, excessive sleepiness, and high risk for obstructive sleep apnea syndrome, and poor sleep quality is related to a high risk for obstructive sleep apnea syndrome among patients with compensated liver cirrhosis.

Quality of sleep, health and well-being in a population-based study.

OBJECTIVE: To estimate the prevalence of poor self-rated sleep and to identify the population subgroups most susceptible to the problem. METHODS: This is a cross-sectional, population-based study developed with data from the Health Survey conducted in the city of Campinas (ISACamp 2014/2015). Data from a sample of 1,998 individuals aged 20 years or older were analyzed. The self-rated quality of sleep was analyzed according to socio-demographic characteristics, morbidities, health behaviors and feeling of well-being. The association of sleep quality with different complaints and characteristics of sleep was also analyzed. Adjusted prevalence ratios were estimed using Poisson multiple regression model allowing for the sample weights. RESULTS: Prevalence of poor self-rated sleep was 29.1% and showed to be significantly higher in women, in individuals aged from 40 to 50 years, migrants, without occupation, physically inactive in leisure context, with common mental disorder (PR = 1.59), with greater number of health problems (PR = 2.33), poor self-rated health (PR = 1.61), and life dissatisfaction. Poor sleep was strongly associated with reports of difficulty in initiating sleep (PR = 4.17), in maintaining sleep (PR = 4.40) and with never or almost never feeling well when waking up (PR = 4.52). CONCLUSIONS: The results identify the population subgroups with poor quality of sleep that deserve greater attention. It also highlight the need to consider, in addition to the presence of comorbidities, mental health and the feeling of well-being in the care of patients with sleep problems and in the interventions planed for promoting healthy sleep.

Cultural adaptation and evaluation of the measurement properties of the Berlin Questionnaire for Brazil.

OBJECTIVE: to produce the Brazilian version of the Berlin Questionnaire (BQ) with evidence of reliability and validity. METHOD: The cultural adaptation was carried out in the following stages: translation, synthesis of translations, back-translation, evaluation by an expert committee and pre-test with 30 participants. Next, the psychometric properties were evaluated with 104 participants who answered the Brazilian version of the BQ and underwent polysomnography (PSG). They also completed a sociodemographic and clinical characterization instrument and the Epworth Sleepiness Scale. Reliability was assessed concerning homogeneity of the items (internal consistency), and criterion validity was tested by comparing the Brazilian version of the BQ with the apnea and hypopnea index (AHI) obtained through PSG. RESULTS: The Brazilian version of the BQ presented evidence of semantic-idiomatic, conceptual and cultural equivalence, with good acceptability and feasibility. The findings demonstrated the reliability of the measure (Cronbach's alpha 0.74). The instrument presented a sensitivity of 81.3%, 86.2%, and 93.8%, and specificity of 82.5%, 54.7% and 50.0% for the risk stratification of obstructive sleep apnea according to the AHI ≥5, ≥15 and ≥ 30 events per hour, respectively. It should be emphasized that the BQ is a screening instrument for obstructive sleep apnea (OSA) and should be combined with a clinical evaluation and later confirmed with PSG. CONCLUSION: The Brazilian version of the Berlin Questionnaire was reliable and valid in the study population.

RESUMO OBJETIVO Estimar a prevalência de sono autoavaliado como ruim e identificar os subgrupos da população mais susceptíveis ao problema. MÉTODOS Trata-se de estudo transversal, de base populacional, desenvolvido com dados de Inquérito de Saúde conduzido no município de Campinas (ISACamp 2014/2015). Foram analisados dados de amostra representativa de 1.998 indivíduos com 20 anos ou mais de idade. A qualidade autoavaliada do sono foi analisada segundo características sóciodemográficas, morbidades, comportamentos de saúde e sentimentos de bem-estar. Analisou-se também a associação da qualidade do sono com diferentes queixas e características do sono. Foram estimadas razões de prevalências e desenvolvido modelo de regressão múltipla de Poisson, considerando-se nas análises os pesos amostrais. RESULTADOS A prevalência de sono autoavaliado como ruim foi 29,1% e mostrou-se significativamente mais elevada nas mulheres, em indivíduos de 40 a 50 anos de idade, migrantes, sem ocupação, fisicamente inativos em contexto de lazer, com transtorno mental comum (RP = 1,59), com maior número de problemas de saúde (RP = 2,33), com saúde autoavaliada como ruim (RP = 1,61) e que manifestavam insatisfação com a vida. Sono ruim esteve fortemente associado com relatos de dificuldade de iniciar o sono (RP = 4,17), de manter o sono (RP = 4,40) e com nunca ou quase nunca se sentir bem-disposto ao acordar (RP = 4,52). CONCLUSÕES Os resultados identificam os segmentos da população com má qualidade do sono que merecem maior atenção e destacam a necessidade de avaliar, além da presença de comorbidades, a saúde mental e a presença de sentimentos de bem-estar no processo de cuidado dos pacientes com problemas de sono e no planejamento de intervenções voltadas à promoção de sono saudável.

Napping, functional capacity and satisfaction with life in older adults: A population-based study.

AIM AND OBJECTIVE: To analyse the association between napping, functional capacity and satisfaction with life in older adult residing in the community. METHOD: A cross-sectional population-based study using data from a health survey conducted in a city of the state of São Paulo. Information on sociodemographic and clinical variables was collected through a questionnaire, as well as the occurrence or not of napping and satisfaction with life. Functional capacity was assessed using the Katz Index and Lawton-Brody Scale. Statistical analysis was performed using the Rao-Scott chi-square test and a hierarchical analysis using stepwise backward multiple Poisson regression. p-Values <0.05 were considered significant. In this paper, we adhere to STrengthening the Reporting of OBservational studies in Epidemiology guidelines. RESULTS: There was predominance of the 60-69 years age group (51.3%) and of females (60.8%). The majority of the older adults (57.5%), of both sexes, reported napping. A higher prevalence of napping was found in the older subjects, the male sex, the subjects without children, those with health problems and those that were partially dependent in instrumental activities of daily living. CONCLUSIONS: The study showed that naps are prevalent in older adults. The need to identify the issues that permeate napping is emphasised, in order to promote health in individuals of this age group, before classifying the practice as beneficial or harmful. RELEVANCE TO CLINICAL PRACTICE: It is essential that health professionals, in their practices, consider the complaints and reports of naps in the elderly, in an attempt to detect and reduce possible consequences in activities of daily living.

ABSTRACT Objective to analyze the formation of symptom clusters in cancer patients. Method Longitudinal study carried out from January to June 2016. Twenty-seven patients were recruited from a public chemotherapy outpatient clinic of a general hospital in Vale do Paraíba Paulista. Data collection was performed through interviews, with the use of the MD Anderson Symptom Inventory, the Pittsburgh Sleep Quality Index and the Visual Analog Sleep Scale. Data were submitted to descriptive and inferential statistical analysis. Results Three symptom clusters were identified over time: organic and functional symptoms; emotional symptoms and sleep; and gastrointestinal symptoms. Conclusion Besides contributing to improve knowledge of symptom clusters in individuals with cancer undergoing outpatient chemotherapy treatment, this study provided insight on how these symptoms behaved during the first four chemotherapy sessions. Therefore, it can be useful in interventions aimed to prevent these symptoms.

Sleep duration, health status, and subjective well-being: a population-based study.

OBJECTIVE: To evaluate, in a population-based approach, the association of extreme sleep duration with sociodemographic factors, health, and well-being. METHODS: We analyzed the data from the 2014/2015 Health Survey in the city of Campinas, State of São Paulo, Brazil (ISACamp), performed with 1,969 individuals (≥ 20 years old). Associations between the independent variable and short (≤ 6 hours) and long (≥ 9 hours) sleep were determined using the Rao-Scott chi-square test. The analyses were adjusted with multinomial logistic regression models. RESULTS: Men, individuals aged 40 to 59, those with higher schooling, those who have one (OR = 1.47, 95%CI 1.02-2.12), two (OR = 1.73, 95%CI 1.07-2.80), or three or more (OR = 1.62, 95%CI 1.16-2.28) chronic diseases, and those with three or more health problems (OR = 1.96, 95%CI 1.22-3.17) were more likely to have a short sleep. The chance of long sleep was higher in widowers and lower in those who have more years of schooling, with higher income, worked, lived with more residents at home, and reported three or more diseases (OR = 0.68, 95%CI 0.48-0.97) and health problems. The chance of either short (OR = 2.41, 95%CI 1.51-3.87) or long sleep (OR = 2.07, 95%CI 1.23-3.48) was higher in unhappy individuals. CONCLUSIONS: These findings highlight the higher chance of short sleep duration among men, among persons in productive age, and among those with a higher level of schooling in a Brazilian city. The association of short sleep with comorbidities and the association of happiness with extremes of sleep duration were also important results to understand the relation of sleep duration with health and well-being.

Fatores associados à ocorrência de cochilos entre idosos comunitários / Factors associated with the occurrence of naps between community elderly

Objetivo: analisar associação gênero, idade, escolaridade, renda familiar, níveis de fragilidade e cinco critérios de fragilidade com ocorrência dos cochilos de idosos. Método: estudo quantitativo, transversal, descritivo. Foram avaliados 3.075 idosos, utilizando questionário sociodemográfico, questão do Minnesota Leisure Activity Questionnaire, fenótipo de fragilidade de Fried e o Mini Exame do Estado Mental. Foram aplicados o teste Qui-quadrado e a regressão logística univariada e multivariada (α=5,0%). Os princípios éticos foram respeitados. Resultados: dos idosos, 61,7% cochilavam durante o dia. Houve associação entre ocorrência de cochilo e idade, gênero e renda familiar. Conclusão: a avaliação dos pacientes deve estudar questões do sono, especialmente considerando idade, sexo e renda, para detectar previamente problemas e desenvolver ações que mantenham a autonomia e a independência dos idosos.
