Ridge Autoregression Estimation: LS Method

In an AR (p)-model, least-squares estimation of the parameters is considered when it is suspected that the parameters may belong to a linear subspace and the estimated covariance matrix is ill-conditioned. Accordingly, we define five estimators and study their properties in an asymptotic setup to discover dominance properties based on asymptotic distributional bias (ADB), MSE (ADMSE) matrices, and under quadratic risks (ADQR).     

Mental Health on the Campus Revisited

Abstract

The author briefly reviews Mental Health on the Campus: A Field Study, published in 1973, noting areas of consensus and points of tension or disagreement that were reported in that study. He then assesses the extent to which the current state of mental health on the campus is an echo of that report. These comparisons form the basis for anticipating the probable direction of future developments in campus mental health. The areas and issues considered include the increased diversity of the student body, the stable incidence of psychotic disorders, the increased prevalence of gender-related diagnoses such as sexual abuse and eating disorders, the continuing financial pressures bearing on campus mental health programs, and the forms of care and treatment that fiscal and other circumstances are imposing. The author concludes that although the resources available and the particular challenges that are faced may have changed, the traditional goals of a campus mental health program, as articulated 75 years ago when the American College Health Association was founded, remain valid, even if they are difficult to attain.     

Nonmedication Treatments for Adult ADHD: Evaluating Impact on Daily Functioning and Well-Being

Abstract

Professor J. Russell Ramsey has written a short book aimed at practicing mental health clinicians, describing various non-medication approaches to the treatment of adult attention-deficit/hyperactivity disorder (ADHD). It includes a variety of strategies, some of which are validated and others of which are currently being developed but do not yet demonstrate effectiveness, alongside the documented effectiveness of medications for the treatment of core symptoms of ADHD, especially inattention, hyperactivity and impulsivity. He includes an up-to-date bibliography and critical evaluations of effectiveness for each treatment, especially functional outcomes. Given the high rate of postsecondary students with ADHD, the book should be helpful for college health professionals who are trying to assist such students.     

Students Left Behind: The Limitations of University-Based Health Insurance for Students With Mental Illnesses

Abstract

A growing trend in college and university health care is the requirement that students demonstrate proof of health insurance prior to enrollment. An increasing number of schools are contracting with insurance companies to provide students with school-based options for health insurance. Although this is advantageous to students in some ways, tying health insurance coverage to school enrollment can leave students vulnerable when they are most in need of help. Students whose health insurance is contingent upon their enrollment face significant lapses in coverage when they are required to leave school. This is especially challenging for students with mental illnesses whose treatment needs often go unmet in the absence of that coverage. The limitations in this system must be addressed as an increasing number of universities and students opt for university-based health insurance plans.     

Medication Abortion Within a Student Health Care Clinic: A Review of the First 46 Consecutive Cases

Abstract

Objective: Medication abortion with mifepristone and misoprostol has been available in the United States since 2000. The authors reviewed the first 46 medication abortion cases conducted at a university-based student health care clinic to determine the safety and feasibility of medication abortion in this type of clinical setting. Participants: Female patients presenting for medication abortion at a student health care clinic between October 1, 2006, and April 1, 2009. Methods: Retrospective consecutive case review. Results: Successful completion not requiring uterine aspiration occurred in 85% of the cases that were not lost to follow-up. Six cases (15%) required uterine aspiration for completion: 3 underwent uterine aspiration only; 3 had aspiration after failing an additional dose of misoprostol. Only 1 patient visited the emergency room. There were no hospitalizations. Conclusions: Medication abortion services in a student health care clinic are safe and feasible. However, additional treatment may be required with some patients.     

Special Considerations in the Treatment of College Students With Bipolar Disorder

Abstract

Bipolar disorder is a relatively common mental disorder that often has its onset during the college years. This means that students simultaneously face both the challenge of late adolescent development and the challenge of adapting to a major mental illness. As a further complication, the college environment is not well suited to the kinds of lifestyle changes that add stability to the lives of people with bipolar disorder. Treatment involves establishing an alliance, education about lifestyle changes, aiding adaptation to the illness, careful medication to minimize side effects, and loosening the affective constriction that can result from fear of relapse. Both the health care provider and student can use the culture of learning and self-discovery in the college setting to the treatment's benefit. As well, the provider can use the time-limited nature of college to lessen ambivalence about making long-term changes.     

Assessing Overweight,Obesity, Diet,and Physical Activity in College Students

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.     

College Health: Biomedical and Beyond

Abstract

Excessive and underage drinking by US college and university students continues to be a significant problem. Curtailing the misuse of alcohol on college campuses is an important goal of college and university administrators because of the many negative consequences resulting from alcohol misuse. As part of their prevention programs, US colleges and universities are required by law to make information about their alcohol policies available to students. Often the source of this information is the school's Web site. The authors evaluated the alcohol-policy information that is available on the Web sites of the 52 top national universities listed in the 2002 rankings of US News and World Report. In general, they found that the information was difficult to find, was located in many areas of the Web site, and did not provide complete information about the school's alcohol policy.
