The current experiment examined whether women with implementation intentions show greater correspondence between their exercise intentions and behaviors, exercise more frequently, and show changes over time in measures of theory of planned behavior (TPB) constructs and scheduling self-efficacy relative to a control group. Participants were 47 women randomly allocated to an implementation intentions or control condition. Measures of TPB constructs and scheduling self-efficacy were assessed at baseline and 8 weeks later. Regression analyses showed that intentions were a significant predictor of behavior for women in the experimental condition (p .01). A significant Condition * Time interaction was found for scheduling efficacy (p .03) and a nonsignificant interaction was found for perceived behavioral control (p = .06), indicating that only the experimental group increased scheduling self-efficacy and perceived behavioral control. No significant group differences were found for the other TPB constructs or self-reported exercise.  相似文献

Traumatic brain injury (TBI) is a major health concern in industrialised countries. Sleep and wake disturbances are among the most persistent and disabling sequelae after TBI. Yet, despite the widespread complaints of post-TBI sleep and wake disturbances, studies on their etiology, pathophysiology, and treatments remain inconclusive. This narrative review aims to summarise the current state of knowledge regarding the nature of sleep and wake disturbances following TBI, both subjective and objective, spanning all levels of severity and phases post-injury. A second goal is to outline the various causes of post-TBI sleep-wake disturbances. Globally, although sleep-wake complaints are reported in all studies and across all levels of severity, consensus regarding the objective nature of these disturbances is not unanimous and varies widely across studies. In order to optimise recovery in TBI survivors, further studies are required to shed light on the complexity and heterogeneity of post-TBI sleep and wake disturbances, and to fully grasp the best timing and approach for intervention.  相似文献

OBJECTIVES: To study the indications for liver transplantation among British Columbia's First Nation population. MATERIALS AND METHODS: A retrospective analysis of the British Columbia Transplant Society's database of Aboriginal and non-Aboriginal liver transplant recipients from 1989 to 1998 was undertaken. For primary biliary cirrhosis (PBC), the transplant assessment database (patients with and without transplants) was analyzed using a binomial distribution and compared with published census data regarding British Columbia's proportion of Aboriginal people. RESULTS: Between 1989 and 1998, 203 transplantations were performed in 189 recipients. Fifteen recipients were Aboriginal (n=15; 7.9%). Among all recipients, the four most frequent indications for liver transplantation were hepatitis C virus (HCV) infection (n=57; 30.2%), PBC (n=34; 18.0%), alcohol (n=22; 11.6%) and autoimmune hepatitis (n=14; 7.4%). Indications for liver transplantation among Aboriginal people were PBC (n=8; 53.3%; P<0.001 compared with non-Aboriginal people), autoimmune hepatitis (n=4; 26.67%; P=0.017), acute failure (n=2; 13.3%) and HCV (n=1). Among all patients referred for liver transplantation with PBC (n=43), 29 (67.44%) were white and 11 (25.6%) were Aboriginal. A significant difference was found between the proportion of Aboriginal people referred for liver transplantation and the proportion of Aboriginal people in British Columbia (139,655 of 3,698,755 [3.8%]; 1996 Census, Statistics Canada) (P<0.001). CONCLUSIONS: Aboriginal people in British Columbia are more likely to be referred for liver transplantation with a diagnosis of PBC but are less likely to receive a liver transplant because of HCV or alcohol than are non-Aboriginal people.  相似文献

Objective: To examine whether socioeconomic and racial/ethnic characteristics contribute independently and in combination to influence douching behavior.
Design: A cross-sectional design.
Setting: United States.
Participants: Women between 14 and 49 years of age who were both interviewed and examined as part of the National Health and Nutrition Examination Survey data collection process.
Main Outcome Measures: Douching rates in women categorized on socioeconomic and racial and ethnic characteristics.
Results: Based on data from 3,522 women, 21% reported recent douching. Separated by race, Black women douche at much higher percentage (47%) than non-Hispanic White (17%), Mexico-born Mexican American women (12.5%), or U.S.-born Mexican American women (19%). Although increasing age and low socioeconomic status are both associated with increased douching, the effects of socioeconomic status on douching vary by race/ethnicity.
Conclusions: Low income and minority racial status contribute both independently and together to influence douching behavior in women. These findings suggest cultural contributions to douching may be especially prevalent in the Black population while Mexican American women born in Mexico may be relatively immune to U.S. cultural influences.  相似文献
