Screening For Adult Adhd In Ontario: A Cross-Sectional Study Examining Sex Differences, Mental Health Correlates And Substance Use, Deanne Daigle

Electronic Thesis and Dissertation Repository

The vast majority of studies on attention-deficit/hyperactivity disorder (ADHD) are based on samples with inherent age, sex, and referral biases. Therefore, the current study used population-based data to 1) estimate the prevalence of adult ADHD (as well as previous diagnosis and medication use using an ADHD screener) and co-occurring psychiatric distress and substance use in Ontario 2) examine the sex differences in ADHD screening status and co-occurring psychiatric distress and substance use and 3) model ADHD screening status as a risk factor for psychiatric distress using the 2011 cycle of the Centre for Addiction and Mental Health Monitor. A positive …

Variation Of Adenoma Prevalence By Age, Sex, Race, And Colon Location In A Large Population: Implications For Screening And Quality Programs, Douglas Corley, Christopher Jensen, Amy Marks, Wei Zhao, Jolanda De Boer, Theodore Levin, Chyke Doubeni, Bruce Fireman, Charles Quesenberry

Chyke A. Doubeni

BACKGROUND and AIMS: Reliable community-based colorectal adenoma prevalence estimates are needed to inform colonoscopy quality standards and to estimate patient colorectal cancer risks; however, minimal data exist from populations with large numbers of diverse patients and examiners. METHODS: We evaluated the prevalence of adenomas detected by sex, age, race/ethnicity, and colon location among 20,792 Kaiser Permanente Northern California members >/=50 years of age who received a screening colonoscopy exam (102 gastroenterologists, years 2006-2008). RESULTS: Prevalence of detected adenomas increased more rapidly with age in the proximal colon (adjusted odds ratio [OR], 2.39; 95% confidence interval [CI], 2.05-2.80; 70-74 vs 50-54 …

Measuring Infertility In Populations: Constructing A Standard Definition For Use With Demographic And Reproductive Health Surveys, Maya N. Mascarenhas, Hoiwan Cheung, Colin D. Mathers, Gretchen A. Stevens

Dartmouth Scholarship

Background: Infertility is a significant disability, yet there are no reliable estimates of its global prevalence. Studies on infertility prevalence define the condition inconsistently, rendering the comparison of studies or quantitative summaries of the literature difficult. This study analyzed key components of infertility to develop a definition that can be consistently applied to globally available household survey data.

Methods: We proposed a standard definition of infertility and used it to generate prevalence estimates using 53 Demographic and Health Surveys (DHS). The analysis was restricted to the subset of DHS that contained detailed fertility information collected through the reproductive health calendar. …

The Symptom Of Fatigue In Primary Care: A Comparative Study Of Health Care Utilization Patterns Using Electronic Medical Records, Kathryn A. Nicholson

Electronic Thesis and Dissertation Repository

The experience of fatigue has been a common problem among community populations for decades. The symptom of fatigue is also a frequent health complaint in primary care practices. Fatigue patients have been shown to be significantly high users of health care resources, particularly when compared to non-fatigued patient populations. To date, an understanding of the presence and the impact of the symptom of fatigue within the context of the Canadian health care system has been understudied.

The objective of this research was to determine the number of patients who were suffering from the symptom of fatigue within a primary care …

Malaria And Related Outcomes In Patients With Intestinal Helminths: A Cross-Sectional Study, Abraham Degarege, Mengistu Legesse, Girmay Medhin, Abebe Animut, Berhanu Erko

Journal Articles: Epidemiology

BACKGROUND: The effects of helminth co-infection on malaria in humans remain uncertain. This study aimed to evaluate the nature of association of intestinal helminths with prevalence and clinical outcomes of Plasmodium infection.

METHODS: A cross-sectional study involving 1,065 malaria suspected febrile patients was conducted at Dore Bafeno Health Center, Southern Ethiopia, from December 2010 to February 2011. Plasmodium and intestinal helminth infections were diagnosed using Giemsa-stained blood films and Kato-Katz technique, respectively. Haemoglobin level was determined using a haemocue machine.

RESULTS: Among 1,065 malaria suspected febrile patients, 28.8% were positive for Plasmodium parasites (P. falciparum =13.0%, P. vivax =14.5%, P. …

The Burden Of Hepatitis C Virus In New York State, Rachel Hart Malloy

Legacy Theses & Dissertations (2009 - 2024)

Hepatitis C virus (HCV) infection is estimated to be the most common chronic blood-borne infection in the United States (US). Annual incidence of HCV in the US peaked in the late 1980's, declined steadily through the 1990's and has plateaued since 2003 with approximately 18,000 new cases in 2008. The morbidity and mortality associated with HCV is expected to rise until at least 2015. Due to the high rate of asymptomatic cases, inherent limitations with target screening recommendations, limitations with screening technologies and scarce resources for surveillance nationwide, quantification of the burden is difficult. US estimates of disease burden have …
