Executive Summary
Diabetes• Diabetesisachronicconditionthatstemsfromthebody’sinabilitytoproduceand/orproperlyuseinsulin.Thebody
needs insulin to use sugar as an energy source. Diabetes can lead to serious complications and premature death. However, if someone has diabetes, steps can be taken to control the disease and lower the risk of complications.
National Diabetes Surveillance System (NDSS)• TheNationalDiabetesSurveillanceSystem(NDSS)isanetworkofprovincialandterritorialdiabetessurveillance
systems. It was created to improve the breadth of information about the burden of diabetes in Canada so that policymakers, researchers, health practitioners, and the general public could make better public and personal health decisions. The NDSS includes federal, and all provincial and territorial governments, non-governmental organizations, national Aboriginal groups, and researchers.
NDSS Highlights• In2005-2006,approximately1.9millionCanadians,oraboutonein17peoplehadbeendiagnosedwith
diabetes - 5.9% overall – 5.5% of girls and women and 6.2 % of boys and men.
• In2005-2006,theprevalence1 of diagnosed diabetes was lower among children and adolescents than adults. Theratesincreasedwithagefromabout2%inindividualsintheir30’stoabout22%,or1in5,inadultsaged 75 to 79 years old.
• Afteradjusting2 for differences in age distributions among provinces and territories, the prevalence1 of diagnosed diabetes was generally found to be highest in the Atlantic provinces (New Brunswick, Nova Scotia, Newfoundland and Labrador) and was lowest in the west (Saskatchewan, Alberta, and British Columbia). The prevalence1 for Ontario was higher than the national average, and for Quebec, prevalence was lower than the national average. Provincial and territorial obesity prevalence, followed a similar pattern; higher in the Atlantic provinces and lower in the western provinces.
• Theage-standardizedprevalence1 of diagnosed diabetes has increased by about 22% between 2001-2002 and 2005-2006.
• By2011,thenumberofCanadianswithdiagnoseddiabetesisexpectedtobeabout2.6million-anaverageannualpercent increase of almost 7% and an increase of about 33% from 2006.
• In2005-2006,199,471individualswerenewlydiagnosedwithdiabetes–arateof6.4per1,000population aged 1 and older, overall, and 5.9 per 1,000 among girls and women and 6.8 per 1,000 among boys and men.
• Thereisanincreasedriskofdevelopingdiabetesoverage40.Theentranceofthebabyboomgenerationintothe older age groups, and the rise in the prevalence1 of obesity, are associated with the rise in the diagnosed diabetes prevalence and incidence rates8. In addition, age-standardized prevalence1 is climbing at 3 times the rate of age-standardized incidence rates8, indicating that the increase in prevalence1 is due, also in part, to improved survival among individuals with diabetes.
• In2005-2006,amongadultsaged20yearsandolder,deathratesofindividualswithdiabetesweretwiceashighasthose in individuals without diabetes.
• Diagnoseddiabetesshortenslifeexpectancyforallages.Forexample,bothmenandwomeninthe25to39yearagegroupswithdiagnoseddiabeteshadabouta9yearreductioninlifeexpectancyin2005-2006.
• In2005-2006,youngeradults(aged20to49)withdiagnoseddiabeteshadabouttwiceasmanyvisitstofamily physicians and 2 to 3 times more visits to specialists than individuals without diabetes. Even in the oldest age groups, individuals with diagnosed diabetes visited physicians about 1.5 times more often than individuals without diabetes.

Diabetes• Diabetesisachronicconditionthatstemsfromthebody’sinabilitytoproduceand/orproperlyuseinsulin.Thebody
needs insulin to use sugar as an energy source. Diabetes can lead to serious complications and premature death. However, controlling the disease can lower the risk of complications.
Type 1 Diabetes • Type1diabetesoccurswhenthebetacellsofthepancreasaredestroyedbytheimmunesystemandnolonger
produce insulin. An adequate supply of insulin is needed to help the body function. It usually develops in childhood or adolescence and there is no known way to prevent type 1 diabetes.
Type 2 Diabetes• Type2diabetesoccurswhenthebodydoesnotmakeenoughinsulinand/ordoesnotrespondwelltotheinsulinit
makes. People are usually diagnosed with type 2 diabetes after the age of 40, although it is now also being seen in children and adolescents.
Gestational Diabetes• Gestationaldiabetesisaformofdiabetesthatdevelopsinwomenduringpregnancyanddisappearsafterdelivery.
Gestational diabetes occurs in about 4% of all pregnancies and increases the risk of developing type 2 diabetes.
Reducing the Risk of Diabetes• Theriskofdevelopingdiabetescanbereducedbymakinghealthylifestylechoices,suchashavingahealthydiet,
losingexcessweightandexercisingregularly.Weightlossof5%to10%hasbeenshowntosignificantlyreduce risk—about 4.5 to 9 kg (10 to 20 lbs.) for a 90-kg (200-lb.) person.
Living with Diabetes • Treatmentdependsonthetypeofdiabetesandcanincludelifestylemodificationand/ormedications,includinginsulin.
Regular physical activity and healthy weight are important factors for effective management of diabetes. Controlling blood glucose, blood pressure and blood lipids are necessary to reduce the complications associated with diabetes. Self-management of diabetes is an essential part of overall care. Regular screening for complications and early treatment can also reduce complications.

It was created to improve the breadth of information about the burden of diabetes in Canada so that policymakers, researchers, health practitioners, and the general public could make better public and personal health decisions.

• Thelinkeddatabaseisusedtodesignateindividualswhohavediabetes4, based on the NDSS validated case criteria, whichusetheInternationalClassificationofDisease(ICD)standarddiabetescodes.
• Currently,theNDSScasecriteriadonotincludewomenwithgestationaldiabetes.Inaddition,thecriteriadonot distinguish between diabetes types in any of the reported rates due to limitations of the physician billing data and the hospital discharge abstract data in identifying type 1 and type 2 diabetes.
• InthelatestversionoftheICDsystem(ICD-10-CA)usedbyhospitalstorecordthedetailsofdiscretehospitalizations,separate codes for type 1 and type 2 diabetes are provided. It is anticipated that as additional ICD-10-CA coded hospital data are accumulated and validated, that it will be possible to analyze and report rates associated with hospitalizationstratifiedbydiabetestype.Forexample,therateofamputationsamongthosewithtype1diabetes versus those with type 2.
• Usingadministrativedataforsurveillance,asintheNDSS,oftenrequiresacompromisewhentryingtoidentifycasesof a disease. It is necessary to balance the possibility of misclassifying people who actually have been diagnosed with diabetes but who have not been captured by the NDSS as a diabetes case (false-negatives) with the reverse where people do not have diabetes but have been captured by the NDSS using the case criteria (false-positives). Validation studies have indicated that the NDSS case criteria minimize both false-negatives and false-positives in order to depict a relatively accurate picture of diagnosed diabetes in Canada. Additionally, there are some people who have not been diagnosed with diabetes, but in fact have the disease. Estimates for the number of people in this category are outside the scope of the NDSS.
PeopleWithDiagnosedDiabetes(Prevalence5)For People Aged 1 and Older:
• In2005-2006,approximately1.9millionCanadiansaged1andolder,orabout1in17,haddiagnoseddiabetes(1,939,247 overall, 925,523 among girls and women and 1,013,724 among boys and men). The prevalence among Canadians was 5.9% overall (5.5% of girls and women and 6.2% of boys and men). (Tables 1 and 2)

• Asanticipated,in2005-2006,asinprioryears,theprevalence5ofdiagnoseddiabeteswassignificantlyloweramongchildren and adolescents than adults. The prevalence increased with age from about 2% among individuals in their 30’stoabout22%,or1in5,adultsaged75to79yearsold.(Figure 1 and Table 2)
• Afteradjusting6 for differences in age distributions among provinces and territories, the prevalence5 of diagnosed diabetes was generally found to be highest in the Atlantic provinces (New Brunswick, Nova Scotia, Newfoundland and Labrador) and was lowest in the west (Saskatchewan, Alberta, and British Columbia). The prevalence for Ontario was higher than the national average, and for Quebec, prevalence was lower than the national average. (Figure 2) Provincial and territorial obesity prevalence, followed a similar pattern; higher in the Atlantic provinces and lower in the western provinces.
• Afteradjusting6 to account for changes in the age distributions over time, the prevalence5 of diagnosed diabetes has increased by about 22% between 2001-2002 and 2005-2006. (Figure 3)

PeopleWithNewlyDiagnosedDiabetes(Incidence8) For People Aged 1 Year and Older:
• In2005-2006,199,471individualswerenewlydiagnosedwithdiabetes–arate8 of 6.4 per 1,000 population aged 1 and older, overall, and 5.9 per 1,000 among girls and women and 6.8 per 1,000 among boys and men. (Tables 1, 2, and Figure 7)
• In2005-2006,incidencerates8 of diagnosed diabetes were lower for children and adolescents than for adults. The rates rosesteeplyafterage45andpeakedamongbothmenandwomeninthe70-74agegroup.Theratesweresignificantlyhigher among men than women over age 40. (Table 2 and Figure 7)
• Afteradjusting6 to account for changes in the age distributions across time, the incidence rates8 of diagnosed diabetes have increased by about 7% between 2001-2002 and 2005-2006. (Figure 8) Rising age-standardized incidence rates8 are likely a reflection of the rising prevalence5 of obesity. In addition, age-standardized prevalence is climbing at 3 times the rate of age-standardized incidence rates, indicating that the increase in prevalence is also due, in part, to improved survival among individuals with diabetes.

HealthServicesUtilizationTwo measures of health services utilization are the number of visits to physicians (family physicians and specialists) and the length (days) of hospital stays.
For Adults Aged 20 Years and Older:
• In2005-2006,youngeradults(aged20to49)withdiagnoseddiabeteshadabout2timesasmanyvisitstofamilyphysicians (Figure 11) and 2 to 3 times as many visits to specialists (Figure 12) than individuals without diabetes. Even in the oldest age groups, individuals with diagnosed diabetes visited physicians about 1.5 times more than individuals without diabetes.
• Duringthe2005-2006fiscalyear,adultswithdiagnoseddiabetesstayedmoredaysinhospitalthanindividualswithoutdiabetes. For hospitalized adults with diagnosed diabetes, aged 20 to 29 and 35 to 54 years old, the number of days stayed in hospital was about 4 to 6 times the number of days stayed by individuals without diabetes. Among those older than 54 years, the ratio of days stay between those with diabetes and those without ranged from 2 to 3. (Figure 13)
For Children and Adolescents Aged 1 to 19 Years Old:
• Childrenandadolescentswithdiagnoseddiabeteshadabout1.5timesmorevisitstofamilyphysicians(Figure 11) and 4 times as many visits to specialists (Figure 12) as children and adolescents without diabetes, in 2005-2006.
• During2005-2006,hospitalizedchildrenandadolescentswithdiagnoseddiabetes,aged1to19,stayedabout 8 to 11 times the number of days in hospital than hospitalized individuals without diabetes. (Figure 13)

Other Health Problems10 Eight heath problems, for which hospitalizations are common among individuals with diagnosed diabetes, are currently tracked by the NDSS. They are chronic kidney disease, lower limb amputations, and cardiovascular disease – which include but are not limited to: hypertensive disease, heart failure, heart attack, ischaemic heart disease, and stroke.
For Adults Aged 20 Years and Older:
• In2005-2006,themostcommonhealthproblemseeninhospitalizationsamongindividualswithdiagnoseddiabeteswas for cardiovascular disease (about 9%). (Table 3)
• During2005-2006,adults,aged20yearsandolder,withdiagnoseddiabeteswerehospitalizedmoreoftenthantheircounterparts without diagnosed diabetes11 (Table 3):
• 23timesmoreoftenwithlowerlimbamputations;

• 3timesmoreoftenwithallcardiovasculardiseases;
• 4timesmoreoftenwithhypertensivediseaseandheartfailureand,
• 3timesmoreoftenwithheartattack,ischaemicheartdisease,andstroke.
NDSS Future PlansThe NDSS provides a valuable source of information about diabetes in Canada. Future work will include:
• ContinuingworkwithFirstNations,Métis,andInuitorganizationstoproduceNDSSdataforanalysis,interpretation, and up-to-date reporting, to gain a better understanding of diabetes among these populations;
• Expandingthebreadthofdatareportingondiabetesandotherrelatedconditionsamongadults,children, and adolescents;
• ExploringtheuseofICD-10-CAdiagnosiscodinginhospitalsandpharmaceuticaldatatodifferentiatebetween types of diabetes; and,
• Developingacollaborativestandardapproachtoimprovinganddocumentingdataquality.
Source: Public Health Agency of Canada, using NDSS data files contributed by provinces and territories, as of September, 2008 *Select comorbid conditions were for the following: cardiovascular disease, hypertensive disease, ischaemic heart disease, acute myocardial infarction, heart failure, cerebrovascular disease, chronic kidney disease, and lower limb amputations. An individual may have more than one comorbid hospitalization, and is only counted once in each category. **Data are rate ratios of age-standardized rates. Rates are age-standardized to the 1991 Canadian population. ^Quebec data were excluded from analysis and data from Nunavut were unavailable. ***When more than one hospitalization is recorded in one of the highlighted cardiovascular disease categories: hypertensive disease, ischaemic heart disease, acute myocardial infarction, heart failure, or cerebrovascular disease, an individual with diagnosed diabetes is counted only once under this broader cardiovascular disease category. ****Lower limb amputations exlcude those caused by trauma or cancer.
