BackgroundTheoretical models argue that coping reduces stress responses, yet no studies have tested whether coping moderates the prospective stress effects on sleep in daily life.PurposeThis study tested if coping moderates the stress-sleep association using a daily, intensive longitudinal design across 7–12 days.Methods326 young adults (Mage = 23.24 ± 5.46) reported perceived stress and coping (problem-focused, emotional-approach, and avoidance) every evening between 20:00–02:00, providing over 2400 nights of sleep data and 3000 stress surveys from all participants. Actigraphy and sleep diaries measured total-sleep-time and sleep efficiency. Multilevel models tested the interaction effects of within- and between-person stress and coping on sleep.ResultsWithin-person problem-focused and emotional-approach coping moderated the within-person stress effects on actigraphic total-sleep-time (both p = 0.02); higher stress predicted shorter total-sleep-time only during high use of problem-focused or emotional-approach coping (both p = 0.01). Between-person avoidance moderated the between-person stress effect on actigraphic total-sleep-time (p = 0.04); higher stress predicted shorter total-sleep-time for high avoidance coping (p = 0.02). Within-person emotional-approach coping buffered the between-person stress effect on actigraphic sleep efficiency (p = 0.02); higher stress predicted higher sleep efficiency for high emotional-approach coping (p = 0.04).ConclusionsThis study showed that daily coping moderates the effects of evening stress on sleep that night. More efforts to cope with stress before bedtime had a short-term cost of shorter sleep that night. However, high use of emotional-approach coping buffered the impact of stress to promote sleep efficiency.  相似文献

We estimated the discriminatory power of area of residence (census tract) on the prevalence of main risk factors for chronic diseases. Results, based on a sample of 21,007 participants from the 2011–2012 National Health Survey of Spain, show a differential influence of the geosocial environment on the four health risk factors. Accounting for census tracts substantially increases the discriminatory power regarding at-risk alcohol consumption, unbalanced diet, and leisure-time sedentarism but not tobacco consumption. However, the socioeconomic characteristics of the tracts played a minor role. Further research on the specific geosocial contextual variables explaining variability in these risk factors is necessary.  相似文献

Incidence and mortality provide information on the burden of cancer morbidity and the potential years of life lost due to cancer. The Spanish Deprivation Index (SDI) has been developed as a standardized measure to study socioeconomic deprivation in Spain at the census tract level. In addition, SDI information can be combined with ecological variables at the population level and data from the High-Resolution European Studies in Cancer. The aim of this study is to characterize socioeconomic inequalities in incidence, excess mortality, premature mortality and net survival for three of the most incident cancers (lung, colon-rectum and breast) in Spain using the SDI. This national population-based study will assess the impact of socioeconomic inequalities using a multilevel modelling approach. Spatial analysis, multilevel modeling, net survival and economic impact assessment will be used. The results will be useful for supporting decision-making, planning, and management of public health interventions aimed at reducing the impact of socioeconomic inequalities in the diagnosis and prognosis of cancer patients in Spain.  相似文献

The paper addresses a critically important area in Canadian immigration and health from both a social and a spatial perspective. It employs multilevel and contextual approaches to examine the social determinants of immigrant health as well as the place effects on self-reported health at a regional and neighborhood scale. The data come from the raw microdata file of the 2005-10 Canadian Community Health Survey (a random national health survey) and the publicly available Canadian Marginalization index based on the 2006 Census. Three populations are compared: Canadian-born, overall foreign-born, and Chinese immigrants. The results suggest various degrees of association between self-reported health, individual and lifestyle behavioral characteristics, and neighborhood material deprivation and ethnic concentration in census tracts. These factors contribute differently to the reported health of Chinese immigrants, Canada's largest recent immigrant group. A healthy immigrant effect is partially evident in the overall foreign-born population, but appears to be relatively weak in Chinese immigrants. For all groups, neighborhood deprivation moderately increases the likelihood of reporting poor health. Ethnic concentration negatively affects self-rated health, with the exception of the slight protective effect of Chinese-specific ethnic density in census tracts. The multilevel models reveal significant area inequalities across Census Metropolitan Areas/Census Agglomerations in risk of reporting unhealthy status, with greater magnitude in the foreign-born population. The vast regional variations in health among Chinese immigrants should be interpreted carefully due to the group's heavy concentration in large cities. The study contributes to the literature on ethnicity and health by systematically incorporating neighborhood contextual effects in modeling the social determinants of immigrant health status. It fills a gap in the literature on neighborhoods and health by focusing on ethnically disparate groups rather than on the general population. By revealing regional disparities in health, the paper adds a spatial perspective to the work on immigrant health.  相似文献

The main purpose of this study was to investigate whether neighborhood ethnic diversity moderated the association between ethnicity and psychological distress in the four largest cities of Netherlands. Multilevel linear regression analysis was used to assess whether the association between ethnicity and psychological distress differed by levels of neighborhood ethnic diversity. Results showed that the Turkish and Moroccan residents reported significantly higher psychological distress than native Dutch and Surinamese residents. In high ethnic diverse neighborhoods Turkish residents reported significantly less psychological distress than in low ethnic diverse neighborhoods. Ethnic diversity amplifies the risk of depression for some but not all ethnic minorities.  相似文献

There remains a dearth of information regarding the surgical complications following multilevel spine surgery in Parkinson’s disease (PD) patients. This retrospective cohort study was performed to address this issue on a nationwide level using the Nationwide Inpatient Sample from 2001 to 2012. More than 25 postoperative variables were analyzed to assess the impact of fusion construct length on each variable. Subsequently, the same analysis was performed on admissions without PD. 4301 PD patients with spine fusion were identified, of whom 934 (21.7%) underwent fusion of at least three levels; the remaining 3367 underwent fusion of 1–2 levels. Patients with 3+ level fusions were more likely to suffer paraplegia (P = .001; OR = 3.0; 95%CI = 1.5–6.1), hematoma/seroma (P = .009; OR = 1.9; 95%CI = 1.2–3.2), IVC filter placement (P = .018; OR = 2.1; 95%CI = 1.1–3.9), RBC transfusion (P < .001; OR = 3.2; 95%CI = 2.7–3.8), PE (P = .027; OR = 4.5; 95%CI = 1.2–16.9), postoperative shock (P = .023; OR = 7.3; 95%CI = 1.3–39.6), ARDS (P < .001; OR = 4.1; 95%CI = 2.7–6.3), VTE (P = .006; OR = 2.6; 95%CI = 1.3–5.4), acute posthemorrhagic anemia (P < .001; OR = 2.0; 95%CI = 1.7–2.4), device-related complications (P < .001; OR = 3.1; 95%CI = 2.3–4.2), and in-hospital mortality (P = .005; OR = 3.4; 95%CI = 1.5–7.4). 3+ level fusions were also more likely to have LOS > 1 week (P < .001; OR = 2.1; 95%CI = 1.8–2.5), and a nonroutine discharge (P = .005; OR = 1.9; 95%CI = 1.4–2.4). 692,173 non-PD patients with spine fusion were identified; 123,964 (17.9%) underwent 3+ level fusion. Differences between 3+ versus 1–2 level fusions were similar to those in PD patient, but unlike PD patients, postoperative infection was significant while in-hospital mortality, PE and VTE were not. Fusion of at least three levels increased morbidity, mortality, and adverse discharge disposition compared with 1–2 level fusions. Nearly 80% of all spine fusions performed in the United States are fewer than three levels. These findings are worth considering during operative decision-making in both PD and non-PD patients.  相似文献

BackgroundNursing turnover is a major issue for health care managers, notably during the global nursing workforce shortage. Despite the often hierarchical structure of the data used in nursing studies, few studies have investigated the impact of the work environment on intention to leave using multilevel techniques. Also, differences between intentions to leave the current workplace or to leave the profession entirely have rarely been studied.ObjectiveThe aim of the current study was to investigate how aspects of the nurse practice environment and satisfaction with work schedule flexibility measured at different organisational levels influenced the intention to leave the profession or the workplace due to dissatisfaction.DesignMultilevel models were fitted using survey data from the RN4CAST project, which has a multi-country, multilevel, cross-sectional design. The data analysed here are based on a sample of 23,076 registered nurses from 2020 units in 384 hospitals in 10 European countries (overall response rate: 59.4%). Four levels were available for analyses: country, hospital, unit, and individual registered nurse. Practice environment and satisfaction with schedule flexibility were aggregated and studied at the unit level. Gender, experience as registered nurse, full vs. part-time work, as well as individual deviance from unit mean in practice environment and satisfaction with work schedule flexibility, were included at the individual level. Both intention to leave the profession and the hospital due to dissatisfaction were studied.ResultsRegarding intention to leave current workplace, there is variability at both country (6.9%) and unit (6.9%) level. However, for intention to leave the profession we found less variability at the country (4.6%) and unit level (3.9%). Intention to leave the workplace was strongly related to unit level variables. Additionally, individual characteristics and deviance from unit mean regarding practice environment and satisfaction with schedule flexibility were related to both outcomes. Major limitations of the study are its cross-sectional design and the fact that only turnover intention due to dissatisfaction was studied.ConclusionsWe conclude that measures aiming to improve the practice environment and schedule flexibility would be a promising approach towards increased retention of registered nurses in both their current workplaces and the nursing profession as a whole and thus a way to counteract the nursing shortage across European countries.  相似文献
