Associations of Chronic Burden, Sleep Characteristics, and Metabolic Syndrome in the Coronary Artery Risk Development in Young Adults Study

Increased Cardiometabolic Risk in Healthy Young Adults With Early Life Stress

OBJECTIVE

This study aimed to evaluate the relationship between early life stress (ELS) and metabolic risk in healthy young adults and assess the role of health behaviors.

METHODS

Young adults aged 18 to 40 years ( N = 190) with no medical conditions or medication usage were recruited from the community. Participants with ELS ( N = 113) had a history of childhood maltreatment, and most also experienced parental loss ( n = 88). Controls ( N = 77) had no history of maltreatment or parental loss. Standardized interviews and self-reports assessed demographics, adversity, medical/psychiatric history, and health behaviors. Blood pressure and anthropometrics were measured, and fasting plasma assayed for lipid profiles, glucose, insulin level, and hemoglobin A 1c . We calculated both a clinical cut-point and continuous composite metabolic risk score based on clinical risk factors and the mean of z scores of each measure, respectively.

RESULTS

ELS was significantly associated with increased clinical cut-point ( β = 0.68, 95% confidence interval [CI] = 0.20-1.17, p = .006) and continuous ( β = 0.23, 95% CI = 0.08-0.038, p = .003) composite metabolic risk scores. On sensitivity analysis, the association of ELS with the continuous composite metabolic risk score was reduced to a trend after adjusting for a range of psychosocial and health predictors ( β = 0.18, 95% CI = 0.00-0.36, p = .053), with both diet and college graduate status significant in the model.

CONCLUSIONS

Healthy young adults with a history of ELS have increased metabolic risk scores as compared with controls. This relationship may be partially due to health behaviors and socioeconomic factors. These findings underline that ELS is an early contributor to metabolic risk.

Dose-effect relationship of different acupuncture courses on chronic insomnia disorder: study protocol for a randomized controlled trial

Background

Chronic insomnia disorder (CID) is increasing in prevalence year by year, is long lasting, and potentially risky. Acupuncture has been widely used in the clinical management of this condition. However, there is still a lack of direct evidence on the dose-effect relationship between different acupuncture courses and clinical efficacy. To identify this relationship, we will design a randomized controlled trial to clarify the difference in efficacy of different acupuncture courses for CID.

Methods and design

This is a prospective, parallel, single center randomized controlled trial. Two hundred and one participants with CID will be randomly divided into three groups (Group A, Group B, and Group C). The three groups will be given acupuncture therapy for 4, 6, and 8 weeks, three sessions per week, with at least 1 day between sessions. Follow-up will continue until the third month after the end of treatment. The primary outcome is the Insomnia Severity Index (ISI), and secondary outcomes include percentage of ISI < 8 points, the Pittsburgh Sleep Quality Index (PSQI), Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS), Fatigue Severity Scale (FSS), medication use, and safety.

Discussion

This study is expected to provide direct evidence for the optimal treatment cycle of acupuncture for CID, as well as to facilitate health economic evaluation.

An Update on Sleep Duration, Obesity, and Mortality Risk in Women

Sleep health is an essential component to overall health. Because of numerous societal, economic, and biological factors, obtaining adequate sleep poses a unique challenge to aging women. Yet, women have been traditionally understudied in sleep research. An increasing body of research supports abnormal sleep duration as a risk factor for obesity, cardiovascular disease, and mortality. This review focuses specifically on 3 areas of the discussion of insufficient sleep in women: (1) the mysterious poor health of long sleepers, (2) the potential underlying mechanisms linking abnormal sleep duration and cardiometabolic health, and (3) the need to investigate multiple levels of social determinants driving sleep disparities.

Research trends in complementary and alternative treatments for insomnia over the past decade: A bibliometrics analysis

Insomnia is the most common sleep disorder, with persistent insomnia being associated with greater risk and leading to a range of functional consequences that place a heavy burden on patients and healthcare systems. A weight of evidence has shown that complementary and alternative medicine (CAM) seems to have a positive effect on improving sleep. However, the research trends of CAM intervention for insomnia have not been studied systematically through bibliometrics. We searched the relevant literature over the past decade in the Web of Science Core Collection database on September 20, 2022 and used CiteSpace and gCLUTO to visually analyze and cluster countries, institutions, authors, journals and keywords. Through screening, 1655 papers were included. In the past decade, the number of articles published in this field shown an annual trend of growth, with explosive growth in 2020. The USA has the largest number of publications, the University of Hong Kong is the leading institution in this field, and the most cited journal is Sleep. Mental condition and quality of life in patients with insomnia, insomnia related to cancer, effect of mindfulness meditation, yoga and aromatherapy on insomnia and the psychiatric symptoms resulting from the COVID-19 pandemic are at the forefront of this field. In this study, bibliometrics and visualization analysis were performed on related studies on CAM intervention for insomnia. This will be the focus and development direction of insomnia treatment in the future to formulate structured treatment plans for traditional Chinese medicine-related CAM, validate large-scale clinical trials, solve cancer comorbidity insomnia and related psychiatric symptoms and deal with mental health-related insomnia after public health outbreaks.

A systematic review of acculturation and sleep health among adult immigrants in the United States

The United States (US) has more immigrants than any other country in the world, with an estimated 44 million non-US-born individuals residing in the country as of 2018. Previous studies have linked US acculturation to both positive and negative health outcomes, including sleep. However, the relationship between US acculturation and sleep health is not well understood. This systematic review aims to identify and synthesize scientific studies on acculturation and sleep health among adult immigrants in the US. A systematic search of the literature was performed in PubMed, Ovid MEDLINE, and Web of Science in 2021 and 2022 with no date limiters. Quantitative studies published anytime in a peer-reviewed journal in English among an adult immigrant population with an explicit measure of acculturation and a sleep health dimension, sleep disorder, or daytime sleepiness measure were considered for inclusion. The initial literature search yielded 804 articles for review; after removing duplicates, applying inclusion and exclusion criteria, and searching reference lists, 38 total articles were included. We found consistent evidence that acculturative stress was associated with worse sleep quality/continuity, daytime sleepiness, and sleep disorders. However, we discovered limited consensus on the association of acculturation scales and acculturation proxy measures with sleep. Our review demonstrated that compared to US-born adult populations, there is a high prevalence of adverse sleep health among immigrant populations, and acculturation likely plays an important role in shaping this disparity, particularly through acculturative stress.
