BACKGROUND: The increasing prevalence of overweight and obesity has necessitated the development of body mass index (BMI) projection models such as the POpulation HEalth Model (POHEM). This study describes the POHEM-BMI model, a microsimulation tool that can be used to support evidence-based health policy making for obesity reduction. DATA AND METHODS: The National Population Health Survey, the Canadian Community Health Survey (CCHS), and the Canadian Health Measures Survey (CHMS) were used to develop and validate a predictive model of BMI for adults and childhood BMI history...

PHOX2B non-polyalanine repeat mutation (NPARM) in patients with congenital central hypoventilation syndrome (CCHS) is generally considered to beassociated with full-time ventilator dependence and severe autonomic nervous system dysfunction. We report a three-generation family with four individualspossessing a novel PHOX2B NPARM (c.245C > T) with variable phenotypes. This mutation was inherited in an autosomal dominant pattern with variablepenetrance. The affected family members with CCHS have a milder phenotype than is typically expected with a NPARM...

Men who have sex with men (MSM) are disproportionately affected by HIV globally, regionally in Canada, and locally in Vancouver. Lack of reliable population size estimates of MSM impedes effective implementation of health care services and limits our understanding of the HIV epidemic. We estimated the population size of MSM residing in Metro Vancouver drawing on four data sources: the Canadian Community Health Survey (CCHS), a cross-sectional bio-behavioural MSM survey, HIV testing services data from sexually transmitted infection (STI) clinics serving MSM, and online social networking site Facebook...

OBJECTIVES: Home ownership as opposed to renting is associated with lower rates of food insecurity, the latter being a marker of household economic deprivation associated with adverse health outcomes. It is unclear whether this relationship persists during a major economic decline, or whether different subgroups of home owners are equally protected. The 2008-2009 recession in Canada was tied to events in the United States related to inappropriate mortgage financing; the impact of the recession on food insecurity among home owners may identify policies to mitigate recessionary outcomes...

OBJECTIVE: To investigate patterns and predictors of help seeking and met/unmet needs for mental health care in a national population health survey. METHOD: Participants were respondents to the 2012 Canadian Community Health Survey on Mental Health (CCHS-MH; n = 25,133). We used regression to identify the diagnostic and sociodemographic predictors of the use of informal supports, primary care, and specialist care, as well as perceived unmet needs. RESULTS: Eleven percent of Canadians reported using professionally led services for mental health or substance use in 2012, while another 9% received informal supports...

INTRODUCTION: A lack of identifiers in health administrative databases limits our understanding of the cancer burden in First Nations. This study compares cancer risk factors and screening between First Nations in Ontario (on and off reserve) and non-Aboriginal Ontarians using two unique health surveys. METHODS: We measured age-standardized prevalence estimates using the First Nations Regional Health Survey (RHS) Phase 2, 2008/10 (for First Nations on reserve) and the Canadian Community Health Survey (CCHS), 2007-2013 (for First Nations off reserve and non-Aboriginal Ontarians)...

BACKGROUND: Misuse of alcohol, including single risky occasion drinking (RSOD) is associated with a number of health, social and economic consequences. While research demonstrates that many factors contribute to individuals' drinking practices, little is known about risk factors that contribute to RSOD in the Canadian population. The objectives of this study are to examine the patterns of RSOD in Canada, to identify factors associated with RSOD, and to explore policy implications. METHODS: The Canadian Community Health Survey (CCHS) 2009-2010 annual component was used to conduct all the analyses in this paper...

BACKGROUND: Ultraviolet radiation (UVR) exposure and a history of sunburn are important risk factors for skin cancer. Sunburn is more common among men, younger age groups, and people in higher income households. Sun protection measures also vary by sex, age, and socioeconomic characteristics. Associations between ambient UVR and sunburn and sun safety measures have not been quantified. DATA AND METHODS: A total of 53,130 respondents aged 18 or older answered a Canadian Community Health Survey (CCHS) module on sun safety, which was administered in six provinces from 2005 to 2014...

In target detection of optical remote sensing images, two main obstacles for aircraft target detection are how to extract the candidates in complex gray-scale-multi background and how to confirm the targets in case the target shapes are deformed, irregular or asymmetric, such as that caused by natural conditions (low signal-to-noise ratio, illumination condition or swaying photographing) and occlusion by surrounding objects (boarding bridge, equipment). To solve these issues, an improved active contours algorithm, namely region-scalable fitting energy based threshold (TRSF), and a corner-convex hull based segmentation algorithm (CCHS) are proposed in this paper...

The use of prescription opioids has increased dramatically in Canada in recent decades. This rise in opioid prescriptions has been accompanied by increasing rates of opioid-related abuse and addiction, creating serious public health challenges in British Columbia (BC), one of Canada's most populated provinces. Our study explores the relationship between dental pain and prescription opioid use among residents in BC. We used data from the 2003 Canadian Community Health Survey (CCHS), which asked respondents about their use of specific analgesic medications, including opioids, and their history of tooth pain in the past month...

HSCR is a congenital disorder of the enteric nervous system, characterized by the absence of neurons along a variable length of the gut resulting from loss-of-function RET mutations. Congenital Central Hypoventilation Syndrome (CCHS) is a rare neurocristopathy characterized by impaired response to hypercapnia and hypoxemia caused by heterozygous mutations of the PHOX2B gene, mostly polyalanine (polyA) expansions but also missense, nonsense, and frameshift mutations, while polyA contractions are common in the population and believed neutral...

BACKGROUND: Research suggests that diabetes mellitus (DM) has a negative impact on employment and workplace injury, but there is little data within the Canadian context. OBJECTIVE: To determine if DM has an impact on various occupational health outcomes using the Canadian Community Health Survey (CCHS). METHODS: CCHS data between 2001 and 2014 were used to assess the relationships between DM and various occupational health outcomes. The final sample size for the 14-year study period was 505 606, which represented 159 432 239 employed Canadians aged 15-75 years during this period...

OBJECTIVE: The increased migration of skilled workers has resulted in a focus on the economic costs of their unsuccessful labor market integration. Few studies investigate the consequences of employment difficulties on immigrants' well-being. Researchers studying over-education and life satisfaction tend to only examine the general population despite high levels of over-education among skilled immigrants. This study examines the relationship between over-education and life satisfaction among both immigrant and native-born workers in Canada...

INTRODUCTION: Positive mental health is increasingly recognized as an important focus for public health policies and programs. In Canada, the Mental Health Continuum-Short Form (MHC-SF) was identified as a promising measure to include on population surveys to measure positive mental health. It proposes to measure a three-factor model of positive mental health including emotional, social and psychological well-being. The purpose of this study was to examine whether the MHC-SF is an adequate measure of positive mental health for Canadian adults...

Pathogenic variants in PHOX2B lead to congenital central hypoventilation syndrome (CCHS), a rare disorder of the nervous system characterized by autonomic dysregulation and hypoventilation typically presenting in the neonatal period, although a milder late-onset (LO) presentation has been reported. More than 90% of cases are caused by polyalanine repeat mutations (PARMs) in the C-terminus of the protein; however non-polyalanine repeat mutations (NPARMs) have been reported. Most NPARMs are located in exon 3 of PHOX2B and result in a more severe clinical presentation including Hirschsprung disease (HSCR) and/or peripheral neuroblastic tumors (PNTs)...

Congenital central hypoventilation syndrome (CCHS) is a rare disorder associated with dysregulation of the autonomic ventilatory response to hypoxia and hypercarbia usually caused by polyalanine repeat expansion mutations in the PHOX2B gene. Non-polyalanine repeat mutations (NPARM) represent approximately 10% of cases, and usually require continuous ventilation during sleep, although our knowledge of disease progression is limited. Here we present a case with a novel NPARMCCHS mutation associated with a premature stop codon for the PHOX2B protein...

Strategies to reduce the burden of blood pressure attributable diseases require knowledge of secular trend in PBP and its determinants. The issues were investigated in the Copenhagen City Heart Study. The design of CCHS is a repeated measures study. Such designs are uniquely suited to studying changes of an outcome and what risk factors may be associated with that outcome. Repeated measures studies are very well suited for trend analysis by using mixed effect analyses. SBP decreased about 2 mmHg in 25 years...

Traffic-light labelling has been proposed as a public health intervention to improve the dietary intakes of consumers. OBJECTIVES: to model the potential impact of avoiding foods with red traffic lights on the label on the energy, total fat, saturated fat, sodium, and sugars intakes of Canadian adults. METHODS: Canadian adults aged 19 and older (n = 19,915) who responded to the Canadian Community Health Survey (CCHS), Cycle 2.2. The nutrient levels in foods consumed by Canadians in CCHS were profiled using the United Kingdom's criteria for traffic light labelling...
