The association between diabetes type, age of onset, and age at natural menopause: a retrospective cohort study using the Canadian Longitudinal Study on Aging.

Objectives: With growing incidence of type 1 diabetes (T1D), type 2 diabetes (T2D), and gestational diabetes, more women are expected to spend a larger proportion of their reproductive years living with a diabetes diagnosis. It is important to understand the long-term implications of premenopausal diabetes type on women's reproductive health including their age at natural menopause (ANM).

Methods: Baseline data from the Comprehensive Cohort of Canadian Longitudinal Study on Aging were used.

A Web-Based Cognitive Behavioral Therapy, Mindfulness Meditation, and Yoga Intervention for Posttraumatic Stress Disorder: Single-Arm Experimental Clinical Trial.

Background: Posttraumatic stress disorder (PTSD) is a debilitating, undertreated condition. The web-based delivery of cognitive behavioral therapy supplemented with mindfulness meditation and yoga is a viable treatment that emphasizes self-directed daily practice.

Objective: This study aims to examine the effectiveness of a web-based cognitive behavioral therapy, mindfulness, and yoga (CBT-MY) program designed for daily use.

Urinary Fluoride Levels among Canadians with and without Community Water Fluoridation.

Drinking water is a major source of dietary fluoride intake in communities with water fluoridation. We examined the association between urinary fluoride adjusted for specific gravity (UF) and tap water fluoride levels, by age and sex, among individuals living in Canada. Participants included 1629 individuals aged 3 to 79 years from Cycle 3 (2012-2013) of the Canadian Health Measures Survey.

Fluoride exposure and duration and quality of sleep in a Canadian population-based sample.

Background: Fluoride from dietary and environmental sources may concentrate in calcium-containing regions of the body such as the pineal gland. The pineal gland synthesizes melatonin, a hormone that regulates the sleep-wake cycle. We examined associations between fluoride exposure and sleep outcomes among older adolescents and adults in Canada.

Association of water fluoride and urinary fluoride concentrations with attention deficit hyperactivity disorder in Canadian youth.

Background: Exposure to fluoride has been linked with increased prevalence of attention deficit hyperactivity disorder (ADHD) in the United States and symptoms of inattention in Mexican children. We examined the association between fluoride exposure and attention outcomes among youth living in Canada.

Method: We used cross-sectional data collected from youth 6 to 17 years of age from the Canadian Health Measures Survey (Cycles 2 and 3).

Factors associated with the timing of the first prenatal ultrasound in Canada.

Background: The aim of this study was to investigate the factors associated with the timing of the first prenatal ultrasound in Canada.

Methods: This was a secondary data analysis of the Maternity Experiences Survey, a cross-sectional survey covering different aspects of pregnancy, labour, birth and the post-partum period. Bivariate and multivariate multinomial logistic regressions were performed to assess the relationship between timing of first prenatal ultrasound and different independent variables.

Fluoride exposure and thyroid function among adults living in Canada: Effect modification by iodine status.

Background: Fluoride exposure has the potential to disrupt thyroid functioning, though adequate iodine intake may mitigate this effect. This is the first population-based study to examine the impact of chronic low-level fluoride exposure on thyroid function, while considering iodine status. The objective of this study was to determine whether urinary iodine status modifies the effect of fluoride exposure on thyroid stimulating hormone (TSH) levels.

Changes in adiposity and other factors in relation to age at natural menopause: analyses from the coronary artery risk development (CARDIA) study.

Objective: The age at natural menopause has subsequent health implications. Earlier age at natural menopause is a risk factor for cardiovascular disease, atherosclerosis, and stroke. Despite extensive study, no clear and conclusive association between anthropometric measures and age at natural menopause has emerged.

The Relationships Between the Geriatric Practice Environment, Nursing Practice, and the Quality of Hospitalized Older Adults' Care.

Purpose: To test the relationships between the geriatric practice environment, geriatric nursing practice, and overall quality of care for older adults and their families as reported by nurses working in hospitals, while controlling for nurse and hospital characteristics.

Design: A cross-sectional tailored survey design was employed. A questionnaire was mailed to a randomly selected sample of nurses whose primary practice area was medicine, surgery, geriatrics, emergency, or critical care in acute care hospitals in Ontario, Canada.

Perceived acceptability and preferences for low-intensity early activity interventions of older hospitalized medical patients exposed to bed rest: a cross sectional study.

Background: Hospitalized older patients spend most of their time in bed, putting them at risk of experiencing orthostatic intolerance. Returning persons to their usual upright activity level is the most effective way to prevent orthostatic intolerance but some older patients have limited activity tolerance, supporting the need for low-intensity activity interventions. Consistent with current emphasis on patient engagement in intervention design and evaluation, this study explored older hospitalized patients' perceived acceptability of, and preference for, two low-intensity early activity interventions (bed-to-sitting and sitting-to-walking), and characteristics (gender, illness severity, comorbidity, illnesses and medications with orthostatic effects, and baseline functional capacity) associated with perceived acceptability and preference.

Age at natural menopause and its associated factors in Canada: cross-sectional analyses from the Canadian Longitudinal Study on Aging.

Background: Early onset of menopause is associated with long-term disease and higher mortality risks. Research suggests that age at natural menopause (ANM) varies across populations. Little is known about factors that affect ANM in Canadian women.

A Multi-Method Study of the Geriatric Learning Needs of Acute Care Hospital Nurses in Ontario, Canada.

Older people are at risk of experiencing functional decline and related complications during hospitalization. In countries with projected increases in age demographics, preventing these adverse consequences is a priority. Because most Canadian nurses have received little geriatrics content in their basic education, understanding their learning needs is fundamental to preparing them to respond to this priority.
