Campus Walkability,Pedometer-Determined Steps,and Moderate-to-Vigorous Physical Activity: A Comparison of 2 University Campuses

Objective and Participants: At 2 Arizona State University (ASU) campuses, the authors measured student activity and distance walked on campus, as well as student-reported walkability around the student union. Methods: Students from ASU-Polytechnic (n = 20, 33% male) and ASU-Tempe (n = 20, 60% male) recorded distance walked on campus and wore physical activity monitors for 5 days. Results: Polytechnic students spent an average of 36.9 minutes in moderate-to-vigorous physical activity each week; Tempe students spent 69.5 minutes (p < .001). At Polytechnic, students walked an average of 7,674 steps per weekday; at Tempe, 11,294 steps (p = .003). Female students at Polytechnic walked an average of 1.3 km/d; at Tempe, 4.3 km/d (p < .001). At Polytechnic, men walked an average of 1.4 km/d; at Tempe, 3.1 km/d (p = .03). Tempe students rated campus walk-ability as very good, whereas Polytechnic students rated it fair (p < .001). Conclusions: Students at both campuses met activity recommendations; noted differences may be attributed to the built environment's contribution to walkability.     

Therapeutic Effects of an Outdoor Activity Program on Nursing Home Residents with Dementia

Abstract

Objective: The purpose of this one-year pilot study was to obtain preliminary information on the effects of an outdoor activity program, in comparison to an indoor activity program, on sleep and behavior in nursing home residents with dementia. Structured activity programs have been shown to improve dementia-related behavior problems, and there are some indications that improved behavior is associated with improved sleep. Previous research has shown that sleep disturbance is common in nursing home residents, and that limited exposure to light bright enough to entrain circadian rhythms contributes to their sleep problems. Thus, we expected to see improvements in behavior in both the outdoor and indoor activity groups, but improvements in sleep in the outdoor activity group only.

Methodology: A two-group (outdoor program, indoor program) two phase (baseline, intervention) design was used. Subjects were randomized to the outdoor or indoor program groups. Sleep and behavior disturbance were assessed over a 10-day period at baseline (usual activity conditions, which were expected to include little or no time spent outdoors) and at intervention (daily structured activity program offered outdoors or indoors). Sleep was assessed with wrist actigraphs with photocells, which also allowed for monitoring of light exposure. Behavior disturbance was assessed with the Cohen-Mansfield Agitation Inventory. Both activity programs were offered Monday-Friday over a 2 week period, included similar content and were offered by research project staff. The analytical approach emphasized primary changes between baseline and intervention measures of sleep and behavioral symptoms in the two activity groups. Because this was a pilot study, the significance level was set a priori at p< 0.10.

Findings: The outdoor activity group experienced significant improvements in maximum sleep duration. Both groups showed significant improvements in total sleep minutes. There also was a significant improvement in verbal agitation in the outdoor activity group.     

Prevalence of Sufficient Physical Activity Among Parents Attending a University

Objective: The benefits of regular physical activity are well documented. However, approximately half of all university students are insufficiently active, and no research to date exists on the activity behavior of university students who are also parents. Participants and Methods: Using an adapted version of the Godin Leisure Time Exercise Questionnaire (ie, the Physical Activity Prevalence Questionnaire), the authors examined the prevalence of sufficient physical activity among 245 parent students from 6 faculties and 12 programs. Results: Half (49.5%) of the students who were not parents (n = 90) were sufficiently physically active, compared with 16% of students who were parents (n = 3, p < .002). The authors found that 33.3% of parents and 13% of nonparents limited their activity level as a result of illness or injury (p < .05). Conclusions: Most parent students in this study were insufficiently active and at potential risk for the negative health consequences of inactivity. This is a grossly understudied population, and researchers must conduct further studies to understand what can be done to facilitate physical activity among this potentially vulnerable group of students.     

An Empirical Examination of Sexual Relations Between Adolescents and Adults

SUMMARY

The American view that adolescent-adult sexual relations are by definition “child sexual abuse” has spread throughout the Western world and reshaped public policy. This paper, originally presented as a talk, examines the scientific validity of this view. A historical perspective traces the conflation of the adolescent experience with rape, incest, and that of the young, prepubescent child. Biological and cognitive perspectives support the view that adolescents have more in common with adults than children. Sweeping claims that adolescents react as children are said to is critically tested by examining two types of relations-those between heterosexual teenage boys and women and those between gay or bisexual teenage boys and men. Non-clinical empirical data show overwhelmingly that such relations are characterized mostly by positive reactions based on consent if not initiative on the part of the minor, with perceived benefit rather than harm as a correlate. It is concluded that the American view is false, and that public policy that heightens official reaction to such relations, such as that currently proposed by the European Union, are either misinformed or disingenuous in alleging to protect when the motive is to control adolescents.

A bio-psycho-social model of successful aging as shown through the variable “physical activity”

In this article, we present and explain a bio-psycho-social model of successful aging with subjective well-being as a criterion of a successful aging process. We focus on physical activity because it is a crucial behavior. Physical activity can support successful aging in two different ways: first, due to its physiological and cognitive effects, and Second, an older person can enhance subjective well-being (SWB) while being physically active. The model points out that an older person can regulate SWB. To do this, an older person should set and pursue personally and culturally valued goals. The strength of the association between setting a goal and goal pursuance, respectively, and SWB depends on the extent a person is able to satisfy psychological needs (autonomy, competence, relatedness). But, the decision as to which goal will be set and pursued does not belong to the older person exclusively. The bio-psycho-social model explains that the chance to enhance SWB is restricted by personal dispositions (e.g., physiological constitution, psychological factors) and social–structural constraints (e.g., predominant stereotype of aging, facilities especially for target groups).
