Abstract

Objective: To report on college student opinions about the scope of college sexual misconduct (CSM), suggested university sanctions, and treatment of students found responsible of CSM.

Participants: In all, 23?US undergraduate students (14 females and 9 males) with a mean age of 20 years.

Methods: Students participated either in female, male, or mixed-sex focus groups that facilitated the discussion of factors related to CSM.

Results: Students provided in-depth feedback on the climate on US college campuses and factors related to CSM. They agreed upon CSM risk factors and context characteristics, but raised different male and female issues across sex groups. They further provided resolute suggestions for the solution of CSM, experienced treatment barriers, and limited victim reporting.

Conclusion: Student focus groups provide important information about the scope of CSM and offer valuable suggestions for the solution of the problem that may be crucial for the development of successful sexual assault interventions.  相似文献

Abstract

Objective: Alcohol has been linked to a variety of risky sexual practices, including inconsistent condom use. Due to the high rates of alcohol consumption among underage college women, greater understanding of the role of alcohol in young women's sexual decision making is warranted. Participants and Methods: Female underage (18- to 20-year-old) social drinkers (N = 94) participated in an experiment in which they projected themselves into a written hypothetical sexual situation with a new partner. One half of the situations portrayed alcohol consumption; one half did not involve alcohol consumption. Their appraisals of the situation's sexual potential, impelling and inhibiting cognitions, and sexual behavior intentions were assessed. Results: Results revealed that alcohol's expectancy effects on young women's unprotected sexual intentions were mediated by their cognitive appraisals of the situation. Conclusions: These findings indicate that alcohol expectancies and their influence on women's sexual decisions should be incorporated into sexual risk reduction efforts.  相似文献

Abstract

Although graduate physical therapy students are taught the principles of fitness for incorporation into their professional lives, they have difficulty finding the time to implement these principles during graduate school. The authors studied 3 successive classes of graduate physical therapy students at the beginning and ending of their respective programs. They found that the women's percentages of body fat were significantly greater over the period of the study. The men's lower extremity strength decreased at the slower speeds (60 degrees/second), and the women showed increased strength at the higher speeds (180 and 240 degrees/second, respectively). Male grip strength significantly increased over the period of the study. To decrease students' percentages of body fat and increase their strength, the authors asserted that physical therapy students should be allowed more time to participate in fitness activities during their graduate school years.  相似文献

Abstract

The authors surveyed 738 college students aged 18 to 27 years to assess overweight, obesity, dietary habits, and physical activity. They used BMI (body mass index) > 25 kg/m2 or BMI > 85th percentile and BMI > 30 kg/m1 or BMI > 95th percentile to estimate overweight and obesity in those aged < 19 years. To define overweight and obesity in those > 20 years, they used BMI > 25 kg/m2 and > 30 kg/m2. They found overweight rates of 21.6% using BMI directly and 16.2% using BMI percentile and obesity rates of 4.9% using BMI directly and 4.2% using BMI percentile. More than 69% of the participants reported < 5 servings of fruits and vegetables per day and more than 67% reported < 20 g of fiber per day; participants reported physical activity on fewer than 3 d/wk. Most college students are not meeting dietary and physical activity guidelines, suggesting the need for prevention interventions and increased understanding of overweight in college students.  相似文献

Abstract

The authors surveyed 614 African American university students to determine the magnitude of cigarette use, identify risk factors, and develop models to predict smoking. More than half (58.3%) of the participants had smoked at least once, and 9.3% of that group were lifetime smokers. Among the lifetime smokers, 71.3% had smoked during the 30 days preceding the survey. More women (66.8%) than men (56.1%) had tried smoking and were classed as lifetime smokers. Residence, parental, and peer smoking (current and childhood) were associated with trying smoking; age, race/ethnicity, and marital status were additional factors for becoming a lifetime smoker. The risk of being a lifetime smoker was reduced when neither friends nor parents of the student smoked and the student viewed spirituality as important. The results of this study add to the growing understanding of health risk behaviors among African Americans and can be useful in reducing smoking.  相似文献

Abstract

The authors applied the stage-of-change construct in the transtheoretical model to examine the distribution of Asian (n = 869), African American (n = 373), White (n = 1322), and Hispanic (n = 535) American undergraduate students across the 5 stages of change for exercise. Stage of change varied as a function of ethnicity. Higher percentages of minorities were in the precontemplation and contemplation stages. The likelihood of being in these stages was from 43% to 82% greater for minorities than for White students. Also examined were the congruency between stage of change and self-reported levels of physical activity. Half of the sedentary students and 15.6% of the active students were misclassified by the stage-of-change procedure. Misclassification rates were higher for minority women (27.8%) than for White women (17.8%) and for Asian students (24.6%) compared with all others (20.6%). The results of this study have implications for the design of physical activity interventions based on stage of change.  相似文献

Abstract

Biological, behavioral, and psychosocial contributions to the gender gap in coronary heart disease (CHD) are discussed. Although CHD is the Number 1 cause of death for both sexes in the industrialized world, CHD mortality rates between these countries are larger than those between men and women, suggesting that biological factors are not the sole influences on the gender gap in CHD. Traditional coronary risk factors cannot explain the rapid increase in CHD mortality among middle-aged men in many of the newly independent states of eastern Europe. However, eastern European men score higher on stress-related psychosocial coronary risk factors (eg, social isolation, vital exhaustion) than men living in the West. Comparisons between the sexes also reveal gender differences in psychosocial and behavioral coronary risk factors, including excessive alcohol consumption and smoking, favoring women. Overall, it appears that men's coping with stressful events may be less adaptive physiologically, behaviorally, and emotionally, contributing to their increased risk for CHD.  相似文献

ABSTRACT

Self-neglect among older adults results in increased morbidity and mortality rates. Depression is strongly linked to self-neglect and when untreated, severely complicates management of health and functional outcomes. The study aims to identify factors correlated with depression to inform approaches to service recruitment and retention that improve long-term outcomes. The sample included urban community-dwelling older adults (n = 96) 65 years of age and older with Adult Protective Services-substantiated self-neglect. All participants completed a range of validated cognitive, functional, and self-report demographic and clinical measures around health and mental health functioning. A secondary data analysis using multivariable logistic regression revealed that a positive screen for alcohol abuse, low self-rated health, and higher self-reported pain were associated with significantly higher odds of self-reported depression. Further research is needed to understand the temporality between these correlates and depression and to inform prevention and intervention practices for self-neglecting older adults.  相似文献

ABSTRACT

Elder abuse increases the likelihood of early mortality, but little is known regarding which types of abuse may be resulting in the greatest mortality risk. This study included N = 1,670 cases of substantiated elder abuse and estimated the 5-year all-cause mortality for five types of elder abuse (caregiver neglect, physical abuse, emotional abuse, financial exploitation, and polyvictimization). Statistically significant differences in 5-year mortality risks were found between abuse types and across gender. Caregiver neglect and financial exploitation had the lowest survival rates, underscoring the value of considering the long-term consequences associated with different forms of abuse. Likewise, mortality differences between genders and abuse types indicate the need to consider this interaction in elder abuse case investigations and responses. Further mortality studies are needed in this population to better understand these patterns and implications for public health and clinical management of community-dwelling elder abuse victims.  相似文献
