OBJECTIVE: To present current recommendations for cardiovascular disease risk reduction in women. DATA SOURCES: Medline databases were searched from 1990 to 2006 using keywords women and cardiovascular risk, hypertension, cholesterol, and hormone replacement therapy, as well as Web sites from scientific associations such as the American Heart Association, American College of Cardiology, Agency for Health Research and Quality, and the Centers for Disease Control for relevant scientific statements and guidelines. STUDY SELECTION: Randomized controlled trials, particularly those that have influenced current practice recommendations, scientific statements, and clinical practice guidelines were selected. DATA EXTRACTION AND SYNTHESIS: Factors contributing to women's particular risk and current practice recommendations. CONCLUSIONS: Current research has clarified the importance of regular exercise (at least 30 minutes/day most days of the week); abstinence from smoking; a diet focused on whole grains, fruits, vegetables, and low-fat protein sources; and maintenance of normal weight. This lifestyle combined with a partnership with a health care provider to maintain a normal blood pressure (115/75 mm Hg) and optimal lipoproteins through pharmacotherapy when indicated can prevent 82% of cardiovascular disease events in women. 相似文献

ObjectiveOur study aimed to further elucidate the mediating role of presleep arousal in the relationship between daily stress and sleep by investigating subjective sleep quality and actigraphy-assessed sleep efficiency (SE) on both within- and between-participant levels in a sample of healthy young women.MethodsMultilevel modeling was applied on electronically assessed data comprising 14 consecutive nights in 145 healthy young women to assess the relationship between daily stress, presleep (somatic and cognitive) arousal, and sleep on both levels between participants and within participants across days.ResultsHigher levels of daily stress were consistently and significantly associated with higher levels of somatic and cognitive arousal. Somatic arousal mediated the relationship between daily stress and worsened subjective sleep quality on the between-participant level, while cognitive arousal mediated the relationship between daily stress and worsened subjective sleep quality on the within-participants level. Unexpectedly, healthy young women showed higher SE following days with above-average stress with somatic arousal mediating this relationship.ConclusionsOur data corroborate the role of presleep arousal mediating the relationship between daily stress and subjective sleep quality. Interestingly this effect was restricted to somatic arousal being relevant on interindividual levels and cognitive arousal on intraindividual levels. For young and healthy individuals who experience high stress and arousal, well-established cognitive–behavioral techniques could be useful to regulate arousal and prevent worse subjective sleep quality. 相似文献

目的:分析健康体检者项目漏检的原因,为提高体检质量提供对策。方法随机抽取4600份体检者体检表,统计漏检项目人数和漏检率,对漏检原因进行调查,并做出分类描述。结果4600份体检表中,体检项目不全739份,漏检率16.1%。漏检的主要原因为体检者体检意识薄弱、只注重仪器检查、轻视手工检查、工作忙怕麻烦、害怕查出问题、体检单位组织者及医院体检中心在管理上有缺陷。结论健康体检者漏检现象比较常见,加强体检工作管理,做好体检健康教育工作,尊重和维护体检者的隐私,以促进体检者完成健康体检。 相似文献

Impaired motor skill acquisition is a feature of older age. Acquisition of new motor skills requires the interplay between different cortical motor areas. Using diffusion tensor imaging we reconstructed cortico-cortical connections between the primary motor cortex (M1) and secondary motor areas in 11 older and 11 young participants who took part in a motor skill acquisition paradigm with the nondominant left hand. Examining the extent to which tract-related integrity correlated with training gains we found that white matter integrity of fibers connecting contralateral M1 with both contralateral (r = 0.85) and ipsilateral supplementary motor areas (r = 0.92) were positively associated in old participants. Also, fibers connecting contralateral M1 with ipsilateral dorsal premotor (r = 0.82) and fibers connecting ipsilateral dorsal premotor and supplementary motor area (r = 0.88) were positively related to skill acquisition (all p < 0.05). A similar structure-behavior relationship was not present in the young control subjects suggesting a critical role of brain structural integrity for motor learning in healthy aging. 相似文献

We have shown previously that pupil diameter increases and the amplitude of the pupillary light reflex is reduced when subjects
are under threat of an aversive event (electric shock), and that light reflex amplitude correlates negatively with subjective
anxiety. We have suggested that the “fear-inhibited light reflex” paradigm could be used as a laboratory model of human anxiety.
In the present study, we examined whether two doses (5 mg and 10 mg) of the anxiolytic drug diazepam would antagonize the
effects of threat on the pupillary light reflex. Twelve healthy male volunteers participated in three weekly sessions, each
associated with one of three treatments (diazepam 5 mg or 10 mg or placebo) in a double-blind, balanced, cross-over design.
The light reflex was recorded during either the anticipation of a shock (“threat” blocks) or periods in which no shocks were
anticipated (“safe” blocks). At the end of each “threat” or “safe” block, subjects rated their anxiety using visual analogue
scales. Two-factor ANOVA (treatment × condition) showed that diazepam treatment antagonized the effect of threat on light
reflex amplitude in a dose-dependent manner but it did not affect the threat-induced increase in pupil diameter. Diazepam
had no effect on the pupillary light reflex in the “safe” condition. Diazepam also reduced subjective anxiety and alertness
in the threat condition. These results show the sensitivity of the threat-induced reduction of light reflex amplitude to anxiolytic
drugs, and provide further evidence for the utility of the fear-inhibited light reflex paradigm as a laboratory model of human
anxiety.
