What Is Comprehensive Sexuality Education Really All About? Perceptions Of Students Enrolled In An Undergraduate Human Sexuality Course, Eva Goldfarb Dec 2005

What Is Comprehensive Sexuality Education Really All About? Perceptions Of Students Enrolled In An Undergraduate Human Sexuality Course, Eva Goldfarb

Department of Public Health Scholarship and Creative Works

The purpose of this study was to use qualitative evaluation techniques to explore the perceptions of students enrolled in undergraduate human sexuality classes regarding their expectations for the course as well as outcomes. One hundred forty-eight students were surveyed at the beginning and again at the end of the semester-long course. While pregnancy and STI prevention were considered important components of their courses, other outcomes associated with positive, healthy sexuality were given greater emphasis. Results suggest that while primary and secondary level sexuality education have been increasingly focused on abstinence-only education with a focus on pregnancy and STI reduction, this …


Cigarette Smoking And Risk Of Glioma: A Prospective Cohort Study, Stephanie A. Navarro Silvera, Anthony B. Miller, Thomas E. Rohan Oct 2005

Cigarette Smoking And Risk Of Glioma: A Prospective Cohort Study, Stephanie A. Navarro Silvera, Anthony B. Miller, Thomas E. Rohan

The etiology of glioma, the most commonly diagnosed malignant brain tumor among adults in the United States, is poorly understood. N‐nitroso compounds are known carcinogens, which are found in cigarette smoke and can induce gliomas in rats. On this basis, it has been hypothesized that cigarette smoking may be associated with an increased risk of glioma. We investigated the association between cigarette smoking and glioma risk in the National Breast Screening Study, which included 89,835 Canadian women aged 40–59 years at recruitment between 1980 and 1985. Linkages to national cancer and mortality databases yielded data on cancer incidence and deaths …

An increasing number of studies are focusing on the potential association between dietary folate intake and risk of various cancers (1), particularly of the colorectum and breast (2, 3). A low folate status can induce misincorporation of uracil into DNA, leading to chromosome breaks in humans and hence increasing cancer risk (4). Alcohol may increase folate requirements in the body and cause relative folate deficiencies (2). Although several findings on the relation between folate intake and ovarian cancer risk are inconsistent (5-9), recent results from two prospective …

Background

Self-efficacy theory proposes that girls who have confidence in their capability to be physically active will perceive fewer barriers to physical activity or be less influenced by them, be more likely to pursue perceived benefits of being physically active, and be more likely to enjoy physical activity. Self-efficacy is theorized also to influence physical activity through self-management strategies (e.g., thoughts, goals, plans, and acts) that support physical activity, but this idea has not been empirically tested.

Methods

Confirmatory factor analysis was used to test the factorial validity of a measure of self-management strategies for physical activity. Next, the construct …


Glycemic Index, Glycemic Load, And Pancreatic Cancer Risk (Canada), Stephanie A. Navarro Silvera, Thomas E. Rohan, Meera Jain, Paul D. Terry, Geoffrey R. Howe, Anthony B. Miller May 2005

Glycemic Index, Glycemic Load, And Pancreatic Cancer Risk (Canada), Stephanie A. Navarro Silvera, Thomas E. Rohan, Meera Jain, Paul D. Terry, Geoffrey R. Howe, Anthony B. Miller

Department of Public Health Scholarship and Creative Works

There is some evidence that plasma insulin and post-load plasma glucose may be associated with the risk of pancreatic cancer. Glycemic index and glycemic load are measures, which allow the carbohydrate content of individual foods to be classified according to their postprandial glycemic effects and hence their effects on circulating insulin levels. Therefore, we examined pancreatic cancer risk in association with a glycemic index (GI), glycemic load (GL), and intake of dietary carbohydrate and sugar in a prospective cohort of 49,613 Canadian women enrolled in the National Breast Screening Study (NBSS) who completed a self-administered food frequency questionnaire between 1980 …

Objectives: To test an original scale assessing perceived school climate for girls' physical activity in middle school girls. Methods: Confirmatory factor analysis (CFA) and structural equation modeling (SEM). Results: CFA retained 5 of 14 original items. A model with 2 correlated factors, perceptions about teachers' and boys' behaviors, respectively, fit the data well in both sixth and eighth-graders. SEM detected a positive, significant direct association of the teacher factor, but not the boy factor, with girls' self-reported physical activity. Conclusions:School climate for girls' physical activity is a measurable construct, and preliminary evidence suggests a relationship with physical activity.

The authors assessed a cohort of 2,335 students from the Minneapolis, Minnesota, area to identify predictors of violent behavior and to determine whether the predictors varied by gender. The sample was 76% White; boys and girls were equally represented. The majority lived with two parents. A measure of violent behavior collected at the end of the eighth-grade year (2000) was entered into Poisson regression against baseline data collected at the beginning of the seventh-grade year (1998). Predictors of violent behavior influencing both boys and girls included depressive symptoms, perceived invulnerability to negative future events, paternal nonauthoritative behavior, and drinking alcohol. …

Objective: To study the relationship between peer-related physical activity (PA) social networks and the PA of adolescent girls.

Methods: Cross-sectional, convenience sample of adolescent girls. Mixed-model linear regression analyses to identify significant correlates of self-reported PA while accounting for correlation of girls in the same school.

Results: Younger girls were more active than older girls. Most activity-related peer social network items were related to PA levels. More PA with friends was significantly related to self-reported PA in multivariate analyses.

Conclusions: Frequency of PA with friends was an important correlate of PA among the peer network variables …

National trends show consistent increases, as well as racial and ethnic dis- parities, in the prevalence of overweight children and adolescents. Such disparity is evident regarding behaviors such as a poor diet and a lack of physical activity and in the prevalence and outcomes of associated health problems. It has been suggested that grounding interventions in cultural traditions and norms are critical for preventing obesity among ethnic and racial minority youth; however, with some notable exceptions, few community interventions have used this approach. Moreover, urban minority youth may face additional barriers to healthful eating and physical activity behaviors, such as …
