Surveillance

By its very nature, screening is characterised by administering a test to presymptomatic or early symptomatic individuals who may benefit from a more effective intervention if it is performed before the usual time of diagnosis.

Far from being a trivial intervention, screening can lead to significant consequences to the people screened. Therefore, before offering screening to workers, its effectiveness and the predominance of benefits over disadvantages must be demonstrated at the…

To our knowledge no data on cancer incidence and mortality among the Aboriginal population of Québec has been published. The only known reference was in a study examining the creation of a cancer registry during a specific period of the 1970s and 1980s. The study found that cancer was virtually non-existent within this population. Indeed, between 1969 and 1989 only 180 cases were reported in Nunavik, though the numbers tended to increase each year during that period. Studies in Canada and…

The survey was conducted during the summer of 2003 using a representative sample of residents aged 12 and older from the nine communities in Iiyiyiu Aschii: Chisasibi, Eastmain, Mistissini, Nemaska, Oujé- Bougoumou, Waskaganish, Waswanipi, Wemindji, and Whapmagoostui.

Aboriginal people generally have higher traumabased death and hospitalization rates than the rest of the population. Nunavik residents were characterized by much higher death rates and lost potential years of life due to trauma (intentional and non intentional) than Quebecers as a whole during the periods 1991-1993 to 1997-1998. The Inuit of Nunavik also have higher hospitalization rates for trauma than do Quebecers as a whole, with a predominance of falls, off-road vehicle accidents,…

Initial observational studies presented the Inuit as a population particularly protected against cardiovascular diseases (CVD), the plague of developed countries. However, because of the abandonment of traditional lifestyles, and the high prevalence of some risk factors (such as smoking 73% and obesity 19%), conclusions from the 1992 Santé Québec health survey of the Inuit population from Nunavik anticipated an increase in CVD. Twelve years later, the Nunavik Inuit Health Survey 2004…

SurvUDI is a network for the epidemiological surveillance of human immunodeficiency virus infection among injection drug users. The network was established in 1995, and covers eight districts in Québec, and Ottawa. Individuals who participate report injecting drugs during the six preceding months and are recruited mainly through centres that provide access to sterile injection equipment. A two-part study on hepatitis C (HCV) was appended to the SurvUDI network. This report presents the…

As of June 30, 2004, 14,773 questionnaires had been administered to 8,964 individuals (Table 1).

Three-quarters of participants are men (6,542/8,964) with an average age of 33. The average age of female participants is 28 (Table 1).

Educational levels are low, with only one in four (269/1,105) participants having completed high school (Table 3; 2003-04 data).

Cocaine is the injection drug most often used (88% of the 8,939 respondents had used cocaine), followed by…

Since 2000, cancer has been the main cause of death in Quebec (Institut de la statistique du Québec, 2003). However, the standardized death rate due to cancer, like most other causes of death, has been declining steadily since the early 1990s (ministère de la Santé et des Services sociaux, 2003; ministère de la Santé et des Services sociaux, 2004), while life expectancy at birth of the Quebec population has increased in recent decades. With the number of seniors growing steadily and the risk…

If the prevalence of diabetes is high in the general Québec population, studies done of Aboriginal communities show that the prevalence in this population are three to four times greater than those observed in the general population (Canada 1999). The prevalence of diabetes has increased significantly over the last 20 years among the Cree population of Northern Québec (Eeyou Istchee) aged 20 years and over, from a few cases before the 1980s, to about 5.2% in the late eighties, to 7.1% in…

Premature mortality caused by cancer and the public health challenge it represents have given rise to a myriad of studies on the contribution of material and social living conditions to varying risks of morbidity and mortality. Thus, European and American studies have shown that cancer mortality—and some cancers more than others—often hits disadvantaged socioeconomic groups and regions hardest, and that this relationship persists even when individual behavior is taken into account. Numerous…
