Changes in Sleep Patterns, Genetic Susceptibility, and Incident Cardiovascular Disease in China.

Importance: The associations of changes in sleep patterns with incident cardiovascular disease (CVD) are not fully elucidated, and whether these associations are modified by genetic susceptibility remains unknown. Objectives: To investigate the associations of 5-year changes in sleep patterns with incident CVD and whether genetic susceptibility modifies these associations. Design, Setting, and Participants: This prospective cohort study of the Dongfeng-Tongji cohort was conducted from 2008 to 2018 in China. Eligible participants included those with complete sleep information at baseline survey (2008-2010) and the first follow-up survey (2013); participants who had no CVD or cancer in 2013 were prospectively assessed until 2018. Statistical analysis was performed in November 2023. Exposures: Five-year changes in sleep patterns (determined by bedtime, sleep duration, sleep quality, and midday napping) between 2008 and 2013, and polygenic risk scores (PRS) for coronary heart disease (CHD) and stroke. Main Outcomes and Measures: Incident CVD, CHD, and stroke were identified from 2013 to 2018. Cox proportional hazards regression models were applied to estimate hazard ratios (HRs) and 95% CIs. Results: Among 15 306 individuals (mean [SD] age, 65.8 [7.4] years; 8858 [57.9%] female and 6448 male [42.1%]), 5474 (35.78%) had persistent unfavorable sleep patterns and 3946 (25.8%) had persistent favorable sleep patterns. A total of 3669 incident CVD cases were documented, including 2986 CHD cases and 683 stroke cases, over a mean (SD) follow-up of 4.9 (1.5) years. Compared with those with persistent unfavorable sleep patterns, individuals with persistent favorable sleep patterns over 5 years had lower risks of incident CVD (HR, 0.80; 95% CI, 0.73-0.87), CHD (HR, 0.84; 95% CI, 0.76-0.92), and stroke (HR, 0.66; 95% CI, 0.54-0.82) in the subsequent 5-year period. No significant effect modification by PRS was observed for sleep pattern change and CHD or stroke risk. However, sleep pattern changes and PRS were jointly associated with the CHD and stroke risk in a dose-dependent manner, with the lowest risk being among those with persistent favorable sleep patterns combined with low PRS (HR for CHD, 0.65; 95% CI, 0.52-0.82 and HR for stroke, 0.48; 95% CI, 0.29-0.79). Conclusions and Relevance: In this cohort study of middle-aged and older Chinese adults, individuals with persistent favorable sleep patterns had a lower CVD risk, even among those with higher genetic risk. These findings highlight the importance of maintaining favorable sleep patterns for CVD prevention.

Disparities in Timeliness of Endometrial Cancer Care: A Scoping Review.

OBJECTIVE: We use the person-centered Pathway to Treatment framework to assess the scope of evidence on disparities in endometrial cancer stage at diagnosis. This report is intended to facilitate interventions, research, and advocacy that reduce disparities. DATA SOURCES: We completed a structured search of electronic databases: PubMed, EMBASE, Scopus, ClinicalTrials.gov, and Cochrane Central Register of Controlled Trials databases. Included studies were published between January 2000 and 2023 and addressed marginalized population(s) in the United States with the ability to develop endometrial cancer and addressed variable(s) outlined in the Pathway to Treatment. METHODS OF STUDY SELECTION: Our database search strategy was designed for sensitivity to identify studies on disparate prolongation of the Pathway to Treatment for endometrial cancer, tallying 2,171. Inclusion criteria were broad, yet only 24 studies addressed this issue. All articles were independently screened by two reviewers. TABULATION, INTEGRATION, AND RESULTS: Twenty-four studies were included: 10 on symptom appraisal, five on help seeking, five on diagnosis, and 10 on pretreatment intervals. Quality rankings were heterogeneous, between 3 and 9 (median 7.2) per the Newcastle-Ottawa Scale. We identified three qualitative, two participatory, and two intervention studies. Studies on help seeking predominantly investigate patient-driven delays. When disease factors were controlled for, delays of the pretreatment interval were independently associated with racism toward Black and Hispanic people, less education, lower socioeconomic status, and nonprivate insurance. CONCLUSIONS: Evidence gaps on disparities in timeliness of endometrial cancer care reveal emphasis of patient-driven help-seeking delays, reliance on health care-derived databases, underutilization of participatory methods, and a paucity of intervention studies. SYSTEMATIC REVIEW REGISTRATION: Given that PROSPERO was not accepting systematic scoping review protocols at the time this study began, this study protocol was shared a priori through Open Science Framework on January 13, 2021 (doi: 10.17605/OSF.IO/V2ZXY), and through peer review publication on April 13, 2021 (doi: https://doi.org/10.1186/s13643-021-01649-x).

A national study of alcohol consumption patterns among population-based U.S. cancer survivors compared with cancer-free individuals.

BACKGROUND: This study characterized alcohol consumption behaviors among adult cancer survivors and determined how these behaviors compared with cancer-free individuals using NHANES data (1999-2016). METHODS: Adjusted odds ratios (aOR) and 95% confidence intervals (CI) were estimated using multinomial logistic regression for the association between cancer survivors vs cancer-free individuals and odds of drinking status (former/current/never drinkers), accounting for demographic and socioeconomic factors. Among current drinkers, multivariable logistic regression was used to calculate the aORs for binge drinking and exceeding moderate drinking. RESULTS: A total of 3113 survivors and 39,527 cancer-free individuals were included. Cancer survivors were less likely to be current drinkers (63.4% vs. 72.6% in cancer-free) and were more likely to be former drinkers (24.4% vs. 15.5% in cancer-free). Cancer survivors had significant lower odds of being current vs. never drinkers (aOR, 0.84, 95% CI: 0.71-0.99). By cancer types, cervical cancer survivors were more likely to be binge drinkers (aOR, 2.51, 95% CI: 1.27-4.92), particularly among women aged ≥ 55 years (aOR, 6.90, 95% CI: 1.28-37.3). CONCLUSION: Given the high odds of binge drinking among cervical cancer survivors, public health strategies are needed to reduce alcohol consumption in this group.

Evaluation of health perceptions and healthcare utilization among population-based female cancer survivors and cancer-free women.

PURPOSE: Cancer survivors are more likely to report having a poor health status when compared to the general population. Few studies have focused on the impact of cancer on health status and healthcare utilization/access outcomes among women from medically underserved populations. METHODS: 25,741 women with and without a history of cancer from the National Health and Nutrition Examination Survey from 1999 to 2016 contributed data. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were estimated using multivariable logistic regression for associations between cancer status and perceived health and healthcare utilization/access outcomes stratified by race/ethnicity, poverty status, education, and comorbidities. RESULTS: 1,897 (7.0%) women had a history of cancer with breast cancer as the most common (n = 671, 35.7%). While most survivors were non-Hispanic white (69.4%), 13.9% were Hispanic, 12.0% were non-Hispanic Black, and 4.6% were additional racial/ethnic groups. Survivors were 1.32 times more likely to be hospitalized within the last year (95% CI 1.11-1.58) and 1.32 times more likely to see a mental health provider within the last year (95% CI 1.05-1.66) compared to cancer-free women. Race/ethnicity was a significant effect modifier in the association between being a survivor and seeing a mental health provider, with Hispanic survivors having the highest odds (aOR 3.44; 95% CI 2.06-5.74; p-interaction < 0.00). CONCLUSION: Our study identifies disparities in healthcare utilization among female cancer survivors, highlighting the importance of evaluating these associations among medically underserved populations. These findings can educate healthcare professionals working with these populations to inform gaps in survivorship care utilization/access.
