Glycaemic Index, Glycaemic Load And Ovarian Cancer Risk: A Prospective Cohort Study, Stephanie A. Navarro Silvera, Meera Jain, Geoffrey R. Howe, Anthony B. Miller, Thomas E. Rohan

Department of Public Health Scholarship and Creative Works

Background

There is some evidence that plasma insulin levels might influence ovarian cancer risk. The glycaemic index (GI) and glycaemic load (GL) are measures that allow the carbohydrate content of individual foods to be classified according to their postprandial glycaemic effects and hence their effects on circulating insulin levels. Therefore, we examined ovarian cancer risk in association with GI and GL, and intake of dietary carbohydrate and sugar.

Methods

The study was conducted 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 (FFQ) between 1980 and …

Benign Proliferative Epithelial Disorders Of The Breast: A Review Of The Epidemiologic Evidence, Stephanie A. Navarro Silvera, Thomas E. Rohan

Department of Public Health Scholarship and Creative Works

Nearly one in four breast cancers is diagnosed before the age of 50, and many early-stage premalignant lesions are present but not yet diagnosed. Therefore, we review evidence to support the strategy that breast cancer prevention efforts must begin early in life. This study follows the literature review methods and format. Exposures during childhood and adolescence affect a woman’s long-term risk of breast cancer, but have received far less research attention than exposures that occur later in life. Breast tissue undergoes rapid cellular proliferation between menarche and first full-term pregnancy, and risk accumulates rapidly until the terminal differentiation that accompanies …

A Case Study Of Pediatric Diarrhea At Murchison District Hospital In Port Shepstone, Kwazulu-Natal, South Africa, T. Smith

Independent Study Project (ISP) Collection

This study investigates pediatric diarrhea in children under 5 years old at Murchison District Hospital in Port Shepstone, South Africa. Hospital Child Pip data was used to determine the number of admissions to the hospital for pediatric diarrhea and its mortality rate. Characteristics of deceased patients including age, malnutrition, and HIV status, were then synthesized with information on patients’ access to clean water and improved sanitation obtained through 20 interviews of mothers of patients as well as caregivers’ infant feeding practices and hygiene practices, such as handwashing with soap. Treatment and prevention of diarrhea was also explored. Murchison’s management of …

A Cohort Study Of Reproductive And Hormonal Factors And Renal Cell Cancer Risk In Women, Gc Kabat, Stephanie A. Navarro Silvera, Ab Miller, Te Rohan

Department of Public Health Scholarship and Creative Works

We examined the association of reproductive and hormonal factors with renal cell cancer risk in a cohort study of 89 835 Canadian women. Compared with nulliparous women, parous women were at increased risk (hazard ratio (HR) 1.78, 95% confidence interval (CI) 1.02–3.09), and there was a significant gradient of risk with increasing levels of parity: relative to nulliparous women, women who had X5 pregnancies lasting 4 months or more had a 2.4-fold risk (HR 1⁄4 2.41, 95% CI 1⁄4 1.27–4.59, P for trend 0.01). Ever use of oral contraceptives was associated with a modest reduction in risk. No associations were …

Ethnic Differentials In Parental Health Seeking For Childhood Illness In Vietnam, Bussarawan Teerawichitchainan, James F. Phillips

Poverty, Gender, and Youth

The recent introduction of user fees for Vietnam’s primary healthcare services has generated concern that economic policies may adversely affect health-seeking behavior and health outcomes of the poor, particularly among impoverished families who are members of socially marginalized minority groups. This Population Council working paper examines this debate by analyzing parental recall of illness and care-seeking for sick children under age 5 recorded by the 2001–02 Vietnam National Health Survey. Ethnic differentials are evident in all geographic and income levels, although adverse effects of minority status are most pronounced among poor households in remote areas. Results suggest that social equity …

Brief Report: Impact Of Classroom Presentations About Health And Help Seeking On Rural Australian Adolescents’ Intentions To Consult Health Care Professionals., Coralie J. Wilson

Frank Deane

Building Bridges-GP-Team (Building Bridges-Team; Wilson et al., 2004c) is a variation of the Building Bridges to General Practice: GPs in Schools program (Building Bridges-GP; Wilson et al., 2004a), which promotes consultation with health care professionals who are local and available for rural and regional adolescent’ consultation. The first major component of Building Bridges-GP-Team involves structured health professional training that provides knowledge in three basic areas: (1) adolescents’ help seeking barriers and ways to address barriers in primary health care; (2) developmental issues relevant to adolescent’ help seeking; and (3) classroom management, presentation strategies, and elementary teaching skills. Training is based …

Depressive Symptoms And Help-Seeking Intentions In Young People., Coralie J. Wilson

Coralie J Wilson

Whether the help-negation effect as demonstrated for suicidal thoughts was also evident for depressive symptoms was investigated in three studies of young people from diverse urban areas. The studies comprised a large sample of younger high school students (years 7-10), a sample of older high school students (years 8-12), and first year university students. A self-report questionnaire that measured help-seeking intentions, prior help-seeking experiences, and depression was administered. Results revealed the strongest inverse association between level of depressive symptoms was with intentions to seek help from parents across all three samples. There was a consistent trend for students to report …

When And How Do Young People Seek Professional Help For Mental Health Problems?, Coralie J. Wilson

Coralie J Wilson

Despite the high prevalence of mental health problems and disorders that develop in adolescence and early adulthood, young people tend to not seek professional help. Young men and young people from Indigenous and ethnic minority groups tend to be those most reluctant to seek help. Young people are more inclined to seek help for mental health problems if they: have some knowledge about mental health issues and sources of help; feel emotionally competent to express their feelings; and have established and trusted relationships with potential help providers. Young people are less likely to seek help if they: are experiencing suicidal …
