Project description:To document trends in self-reported sleep duration for the noninstitutionalized U.S. civilian population from 2004 to 2017 and examine how sleep trends vary by race/ethnicity. We use data from the National Health Interview Survey (NHIS) for U.S. noninstitutionalized adults aged 18-84 from 2004 to 2017 (N = 398 382). NHIS respondents were asked how much they slept in a 24-hour period on average, which we categorized as ≤6 hr (short sleep), 7-8 hr (adequate sleep), and ≥9 hr (long sleep). We used multinomial logistic regression models to examine trends in self-reported sleep duration and assess race/ethnic differences in these trends. Our models statistically adjusted for demographic, socioeconomic, familial, behavioral, and health covariates. The prevalence of short sleep duration was relatively stable from 2004 to 2012. However, results from multinomial logistic regression models indicated that there was an increasing trend toward short sleep beginning in 2013 (b: 0.09, 95% CI: 0.05-0.14) that continued through 2017 (b: 0.18, 95% CI: 0.13-0.23). This trend was significantly more pronounced among Hispanics and non-Hispanic blacks, which resulted in widening racial/ethnic differences in reports of short sleep. Recent increases in reports of short sleep are concerning as short sleep has been linked with a number of adverse health outcomes in the population. Moreover, growing race/ethnic disparities in short sleep may have consequences for racial and ethnic health disparities.

Project description:ImportanceHistorically marginalized racial and ethnic groups are generally more likely to experience sleep deficiencies. It is unclear how these sleep duration disparities have changed during recent years.ObjectiveTo evaluate 15-year trends in racial and ethnic differences in self-reported sleep duration among adults in the US.Design, setting, and participantsThis serial cross-sectional study used US population-based National Health Interview Survey data collected from 2004 to 2018. A total of 429 195 noninstitutionalized adults were included in the analysis, which was performed from July 26, 2021, to February 10, 2022.ExposuresSelf-reported race, ethnicity, household income, and sex.Main outcomes and measuresTemporal trends and racial and ethnic differences in short (<7 hours in 24 hours) and long (>9 hours in 24 hours) sleep duration and racial and ethnic differences in the association between sleep duration and age.ResultsThe study sample consisted of 429 195 individuals (median [IQR] age, 46 [31-60] years; 51.7% women), of whom 5.1% identified as Asian, 11.8% identified as Black, 14.7% identified as Hispanic or Latino, and 68.5% identified as White. In 2004, the adjusted estimated prevalence of short and long sleep duration were 31.4% and 2.5%, respectively, among Asian individuals; 35.3% and 6.4%, respectively, among Black individuals; 27.0% and 4.6%, respectively, among Hispanic or Latino individuals; and 27.8% and 3.5%, respectively, among White individuals. During the study period, there was a significant increase in short sleep prevalence among Black (6.39 [95% CI, 3.32-9.46] percentage points), Hispanic or Latino (6.61 [95% CI, 4.03-9.20] percentage points), and White (3.22 [95% CI, 2.06-4.38] percentage points) individuals (P < .001 for each), whereas prevalence of long sleep changed significantly only among Hispanic or Latino individuals (-1.42 [95% CI, -2.52 to -0.32] percentage points; P = .01). In 2018, compared with White individuals, short sleep prevalence among Black and Hispanic or Latino individuals was higher by 10.68 (95% CI, 8.12-13.24; P < .001) and 2.44 (95% CI, 0.23-4.65; P = .03) percentage points, respectively, and long sleep prevalence was higher only among Black individuals (1.44 [95% CI, 0.39-2.48] percentage points; P = .007). The short sleep disparities were greatest among women and among those with middle or high household income. In addition, across age groups, Black individuals had a higher short and long sleep duration prevalence compared with White individuals of the same age.Conclusions and relevanceThe findings of this cross-sectional study suggest that from 2004 to 2018, the prevalence of short and long sleep duration was persistently higher among Black individuals in the US. The disparities in short sleep duration appear to be highest among women, individuals who had middle or high income, and young or middle-aged adults, which may be associated with health disparities.

Project description:ObjectivesTo investigate the heterogeneous effects of education on sleep duration for Black and White adults and how the education effects changed between 2004 and 2018.MethodsA total of 251,994 adult participants in the 2004 to 2018 National Health Interview Survey were included in pooled cross-sectional data analyses. Separately for Black and White men and women, we calculated prevalence ratio and average marginal probability of short sleep (<7 hours) for each education level over the study period based on weighted logistic regression models.ResultsOpposite educational gradients in short sleep were observed between Black and White adults. Greater educational attainment was associated with lower likelihood of short sleep among White adults but higher likelihood of short sleep among Black adults. Such heterogeneous educational gradients were robust after accounting for a set of socioeconomic, family, and health factors and persisted between 2004 and 2018.ConclusionsThe health implications of education are not uniform in the US population, and heterogeneous education effects on sleep duration persisted over the past decade. More scholarly attention is needed to identify challenges and barriers that may be unique for race, sex, and education subpopulations to maintain healthy sleep.

Project description:This study analyzed trends in the incidence and mortality of laryngeal cancer (LC) in China from 2004 to 2018, provided projections up to 2033, and identified contributing factors influencing these trends. LC data were obtained from the Chinese Cancer Registry Annual Reports for 2004 to 2018. Estimated Annual Percent Change (EAPC) and 95% confidence intervals (CI) were calculated using Joinpoint Regression Software to evaluate trends. LC incidence and mortality rates in registry areas, combined with national population data, were used to estimate new cases and deaths. Projections were made to 2033, and a decomposition analysis identified factors influencing trends. From 2004 to 2018, the age-standardized incidence rate (ASIR) of LC decreased from 1.29 to 1.14 per 100,000, with an EAPC of -1.75% (95% CI: -2.36% to -1.12%). The age-standardized mortality rate (ASMR) also declined from 0.67 to 0.61 per 100,000, with an EAPC of -0.76% (95% CI: -1.28% to -0.25%). Mortality among males aged 60-69, however, showed a significant increase. Population growth and aging contributed to the rise in LC cases and deaths, while epidemiological factors partially offset these increases. By 2033, ASIR and ASMR for males and ASIR for females are projected to decrease, while ASMR for females is expected to rise. ASIR and ASMR in China showed a declining trend from 2004 to 2018, with further decreases projected through 2033. Yet, rising mortality in older males underscores the need for targeted prevention and early detection. Population aging and growth are key drivers of the LC burden, although epidemiological improvements have helped mitigate case increases. Comprehensive public health strategies remain essential to reduce LC impact in China.

Project description:IntroductionGeographic and urbanization differences in female suicide trends across the U.S. necessitates suicide prevention efforts on the basis of geographic variations. The purpose of this study was to assess female suicide rates by mechanism within Census divisions and by urbanicity to help inform geographically tailored approaches for suicide prevention strategies.MethodsData from 2004 to 2018 were obtained from the National Vital Statistics System (analyzed in 2021). Annual counts of female suicides were tabulated for firearm, suffocation, and drug poisoning and stratified by the U.S. Census division and urbanicity. Age-adjusted rates were calculated to describe female suicide incidence by geographic areas and urbanicity. Data were analyzed annually and by 5-year timeframes. Trends in annual female suicide rates by mechanism for 3 urbanization levels were identified using Joinpoint Regression. Annual percent change estimates were calculated for age-adjusted female suicide rates between 2004 and 2018.ResultsFemale suicide rates by mechanism were not homogeneous within Census divisions or by urbanization levels. Suicide rates by mechanism across Census divisions within the same urbanization level varied (range=3.38-11.15 [per 100,000 person per year]). From 2014 to 2018 in large metropolitan areas in the northern divisions, rates for suffocation were higher than for firearms and drug poisoning. During the same period, in all urbanization levels in southern divisions, rates for firearms were higher than for suffocation and drug poisoning.ConclusionsFemale suicide mechanisms vary by urbanization level, and this variation differs by region. These results could inform female suicide prevention strategies on the basis of mechanism, urbanization, and geographic region.

Project description:BACKGROUND:Stroke is a major cause of death and disability worldwide. Over the years, traditional medicines for stroke treatment have undergone tremendous progress, but few bibliometric studies have been performed. This study explored the trends and issues relating to the application of traditional medicine in stroke research. METHODS:A bibliometric search was performed in the Web of Science Core Collection database to identify studies that investigated the application of traditional medicine in stroke management. CiteSpace VI and Excel 2016 were used to analyze information from the retrieved studies. Activity index and attractive index were used to explore the worldwide development modes. RESULTS:A total of 1083 English articles published between 2004 and 2018 were identified. Over the last 15 years, the developments in research occurred in three geographic clusters. The development modes were investigated and classified into 4 categories. In mainland China, the number and impact of research showed an increasing trend over the study period. The United States played a leading role in this topic. Three clusters of institutes and the majority of authors mainly came from South Korea, Taiwan and mainland China. Reperfusion injury and angiogenesis were identified as the potential topics likely to dominate future research in this field. CONCLUSION:The progress of studies on traditional medicine for stroke could be explained by the global attention to traditional medicine, the geospatial proximity for research collabration, and the increasing resources invested. Based on a large amount of existing research, researchers engaged in this topic should objectively consider the influential studies to identify and solve the common issues worldwide.

Project description:With the re-emergence of brucellosis in mainland China since the mid-1990s, an increasing threat to public health tends to become even more violent, advanced warning plays a pivotal role in the control of brucellosis. However, a model integrating the autoregressive integrated moving average (ARIMA) with Error-Trend-Seasonal (ETS) methods remains unexplored in the epidemiological prediction. The hybrid ARIMA-ETS model based on discrete wavelet transform was hence constructed to assess the epidemics of human brucellosis from January 2004 to February 2018 in mainland China. The preferred hybrid model including the best-performing ARIMA method for approximation-forecasting and the best-fitting ETS approach for detail-forecasting is evidently superior to the standard ARIMA and ETS techniques in both three in-sample simulating and out-of-sample forecasting horizons in terms of the minimum performance indices of the root mean square error, mean absolute error, mean error rate and mean absolute percentage error. Whereafter, an ahead prediction from March to December in 2018 displays a dropping trend compared to the preceding years. But being still present, in various trends, in the present or future. This hybrid model can be highlighted in predicting the temporal trends of human brucellosis, which may act as the potential for far-reaching implications for prevention and control of this disease.

Project description:ObjectiveTo determine if the declining trend in U.S. youth cigarette smoking changed after e-cigarettes were introduced, and if youth e-cigarette users would have been likely to smoke cigarettes based on psychosocial and demographic predictors of smoking.MethodsAn interrupted time series analysis was used for cross-sectional data from the 2004 to 2018 National Youth Tobacco Surveys (NYTS) to assess changes in cigarette and e-cigarette use over time. A multivariable logistic regression model used 2004-2009 NYTS data on psychosocial risk factors to predict individual-level cigarette smoking risk from 2011 to 2018. Model-predicted and actual cigarette smoking behavior were compared.ResultsThe decline in current cigarette smoking slowed in 2014 (-0.75 [95% CI: -0.81, -0.68] to -0.26 [95% CI: -0.40, -0.12] percentage points per year). The decline in ever cigarette smoking accelerated after 2012 (-1.45 [95% CI: -1.59, -1.31] to -1.71 [95% CI: -1.75, -1.66]). Ever and current combined cigarette and/or e-cigarette use declined during 2011-2013 and increased during 2013-2014 with no significant change during 2014-2018 for either variable. The psychosocial model estimated that 69.0% of current cigarette smokers and 9.3% of current e-cigarette users (who did not smoke cigarettes) would smoke cigarettes in 2018.ConclusionsThe introduction of e-cigarettes was followed by a slowing decline in current cigarette smoking, a stall in combined cigarette and e-cigarette use, and an accelerated decline in ever cigarette smoking. Traditional psychosocial risk factors for cigarette smoking suggest that e-cigarette users do not fit the traditional risk profile of cigarette smokers.

Project description:ObjectivesTo investigate the focuses and trends of the studies on pediatric palliative care (PPC) and provide directions for future research.MethodsRelevant papers about PPC published from 2004 to 2018 were analyzed using bibliometric analysis methods, including co-word analysis, biclustering analysis, and strategic diagram analysis. The included papers were divided into three groups based on the publication time, including 2004-2008, 2009-2013, and 2014-2018.ResultsA total of 1132 papers were published between 2004 and 2018, and there were 293 papers published between 2004 and 2008, 396 between 2009 and 2013, and 443 between 2014 and 2018. There were 42 high-frequency MeSH terms/MeSH subheadings in papers published between 2004 and 2018, including 12 between 2004 and 2008, 13 between 2009 and 2013, and 17 between 2014 and 2018.ConclusionStudies on PPC were making progress, with the increasing number, expanding scope, and uneven global distribution. Integration palliative care into pediatrics, cancer treatments in pediatric oncology, education methods on PPC, and establishment of professional teams were the major themes during 2004-2008, then the themes changed into establishing interventions to enhance the quality of life of the patients and parents, building professional-family relationship, and investigating attitude of health personnel in PPC during 2009-2013 and subsequently turned into communication skills, end-of-life decision making, and guidelines making on PPC during 2014-2018. Underdeveloped and protential themes including effective approaches to deal with the ethical dilemmas, training programs on communication skills, family support and guideline making are worth studying in the future.

Project description:BackgroundSleep's impact on the human immune system and inflammatory responses makes it a potential risk factor for lung function impairment. However, the relationship between sleep duration and lung function impairment in middle-aged and young adults has been rarely investigated.MethodsA total of 9,284 aged 20-64 years were categorized into four groups according to sleep duration (≤ 6 h, 7 h, 8 h, and ≥ 9 h), with 7 h as the reference, by using the U.S. NHANES data, 2007-2012. Forced expiratory volume in the 1 s (FEV1), forced vital capacity (FVC), FEV1 to FVC (FEV1/FVC) ratio, peak expiratory flow (PEF), and forced expiratory flow at 25-75% (FEF25 - 75%) were measured by spirometry. Restrictive impairment was defined as baseline FVC < 80% predicted and obstructive impairment as FEV1/FVC < 0.70. Generalized linear regression and logistic regression were performed to estimate the associations between sleep duration and lung function.ResultsCompared with 7 h of sleep duration, shorter and longer sleep duration were associated with decreases in FEV1 (≤ 6 h: β=-0.010, 95% CI=-0.014 to -0.006; 8 h: β=-0.005, 95% CI=-0.009 to -0.001), FVC (≤ 6 h: β=-0.018, 95% CI=-0.014 to -0.007; 8 h: β=-0.005, 95% CI=-0.009 to -0.002), and PEF (≤ 6 h: β=-0.006, 95% CI=-0.010 to -0.002; 8 h: β=-0.007, 95% CI=-0.011 to -0.002; ≥ 9 h: β=-0.012, 95% CI=-0.020 to -0.004). Similarly, shorter (≤ 6 h: OR = 1.346, 95% CI = 1.065 to 1.700) and longer (≥ 9 h: OR = 1.827, 95% CI = 1.236 to 2.700) sleep duration were associated with increased risks of restrictive impairment. Moreover, the aforementioned associations were more pronounced among male participants.ConclusionsCompared with 7 h of sleep duration, shorter and longer sleep duration were associated with impaired lung function among adults aged 20-64 years, and these associations were stronger among males.
