Caffeine is the most widely used psychoactive substance in the world and is known to disrupt healthy sleep. However, very few studies have directly tested the effect of caffeine abstinence on sleep, and these have yielded inconsistent findings. The purpose of the present study was to examine changes in sleep following caffeine abstinence and examine the extent to which characteristics of habitual caffeine use moderated this change. Participants included 66 healthy, young adults with habitual caffeine use and poor sleep. During the 2‐week baseline, sleep was assessed using wrist actigraphy and daily caffeine use was assessed with bedtime diaries. Eligible participants then completed 1 week of caffeine abstinence, during which sleep was measured with wrist actigraphy. Multilevel models found no significant differences between either mean levels or growth trajectories of total sleep time or sleep efficiency between baseline and caffeine abstinence. Mean levels of sleep onset latency also did not differ between baseline and caffeine abstinence. A small but significant quadratic effect was observed, such that sleep onset latency decreased during the first few days of caffeine abstinence, then increased to levels above baseline. Characteristics of caffeine use did not moderate changes in sleep between baseline and caffeine abstinence. These data suggest that abstaining from caffeine may not result in long‐term sleep improvement for habitual caffeine users, which contradicts the common sleep health recommendation. The present findings encourage more rigorous investigation of the effectiveness of caffeine restriction on sleep.  相似文献

Objectives

This paper introduces some epistemology about mental health developments and how it leads to reconsider the landscape of clinical practices.

Materials

From an epistemological point of view, the author reviews several writings about mental hygiene going back to the nineteenth century. It clarifies the common roots between mental hygiene and mental health. Then, the article examines the first World Health Organization's reports, that shed light on psychiatric and political issues in the middle of the twentieth century, which allows to reach out the foundations of mental health as a discursive practice.

Results

The review of the developments from “mental hygiene” to “mental health” highlights a general climate of redesign on many points: Mental health as a discursive space is characterized by an expansion of its address field. It is not only addressed to specialists, psychiatrist and psychiatric patients, but also, and above all, to every citizen. Psychic suffering, as far as mental illness, is part of a larger whole including what preserves or deteriorates the proper functioning of an individual, within society. Mental health is at the crossroads of financial, political, citizen's rights and social interests. Contemporary mental health relies on the objectives of prevention and promotion. Clinical practices are organized by some discourses with mental health as a key word. At the turn of 2000s, French psychiatry has been impacted by many shuffles in health policies. However, the roots of these restructuring are not new, as they update an old interest in safeguarding public health, funds and welfare. Psychic suffering and mental illness recently enter the field of “psychic disability”. It brought social benefits such as financial assistance from the state. It may also contribute to the campaigns of awareness-raising and destigmatization among the public opinion. However, financial and subjective effects do not perfectly match. In other words, the benefits listed above should not lead to desert the listening of the users’ experience in its singularity.

Conclusions

The developments of mental health point out a reorganization in the psychiatric field and open new clinical challenges. If the spaces of singularity and universal are in a permanent relationship, the political and economic sides cannot answer or evacuate the subjectivity posed by the subject and his suffering. It should lead to focus on a clinical practice driven by a subtle listening, which does not exclude psychopathology and recognizes the importance of alterity.  相似文献

This study aimed to investigate the effectiveness of an oral health promotion intervention implemented in special care establishments by dentists trained online. Twenty‐six dentists intervening in 27 French special care establishments undertook a standardised oral health promotion intervention, including a conference presentation for care staff and hands‐on toothbrushing workshops. Oral hygiene status of the residents was performed at baseline and at 6 months, and were compared using the McNemar test. Mixed logistic regression was performed to identify the factors associated with an improvement of dental plaque removal. The oral health intervention was completed by 890 residents: 445 children, 373 adults and 72 elderly adults. At baseline, dental plaque was observed for 79.8% of the 797 dentate residents. Among the 691 dentate residents included in the final analysis, dental plaque removal was improved for 34%. Improvement in dental plaque removal was recorded more often for the group of 13 to 20‐year‐old residents (OR = 1.97; 95% CI = 1.15–3.38). The results indicate that this programme failed to significantly improve the dental plaque removal of the residents. More research is needed to understand the limiting factors of such interventions.  相似文献

目的 研究口腔卫生状况与非吸烟非饮酒女性口腔癌的关系。 方法 收集2012年10月-2017年9月我院口腔颌面外科经术后病理确诊的非吸烟非饮酒女性口腔癌患者162例,同期选取在该院体检的214位非吸烟非饮酒健康女性作为对照组。口腔卫生考察指标包括刷牙频率、牙齿缺失数、口腔不良修复体、规律性看牙医、复发性口腔溃疡。应用多因素logistic回归模型分析口腔卫生评分与非吸烟非饮酒女性口腔癌的关联。 结果 刷牙频率<2次/d、牙齿缺失≥5颗、有口腔不良修复体、无规律性看牙医、有复发性口腔溃疡是非吸烟非饮酒女性口腔癌的危险因素(均P<0.05),OR(95%CI)值分别为1.49(1.09~2.08)、1.80(1.16~2.84)、1.51(1.04~2.23)、1.74(1.16~2.57)、7.29(3.98~13.35)。多因素 logistic回归模型分析结果显示,口腔卫生评分与非吸烟非饮酒女性口腔癌发生存在关联,分值越大,危险程度就越高(χ2=24.179,P<0.001)。 结论 口腔卫生状况与非吸烟非饮酒女性口腔癌发生具有一定的关系  相似文献
