1 Demand and Burden of Dental Care in Canadian Households Mustafa Andkhoie, MPH PhD student, Epidemiology University of Saskatchewan May 27 th, 2015

2 Introduction Dental Health Expenditure In Canada second-largest share of private-sector health care spending in 2010 annual growth of 5.9% since only 5% total dental health expenditure in Canada is publicly funded

3 Introduction Main source of financing for dental care: Employment-based insurance and out-of-pocket (OOP) expenditure 62% of Canadians have private dental insurance, 6% have public insurance and 32% have no dental insurance.

4 Purpose The purpose of this study was to examine the financial burden associated with out-of-pocket dental spending in Canada in order to investigate inequities requiring policy interventions.

5 Research Questions 1. A linear model was used to estimate the income elasticity of Canadians with respect to dental care. 2. A logistic model was used to identify the factors that predict the demand for dental care in Canada. 3. A multinomial model was used to identify the subsets within the Canadian population who were more or less likely to have higher or lower burden of dental expenditure on their income.

6 Study Design Survey of Household Spending: 2009 cycle (published by Statistics Canada) Variable of interest Control variables Province Income Private dental insurance Age Sex and Marital Status Rural Residence Employment and Education Household Size

7 Model 1: Income Elasticity Sensitivity of dental demand with change in household income Income elastic = Normal necessity good Example, if income increases by 10% then dental expenditure increase by 1.46%, ceteris paribus.

8 Model 2: Demand for Dental Care Odds of spending on dental care in a household in Canada (n=9,831) Variable Odds Ratio Variable Odds Ratio Income Age $100,000 < 1.937* 65 and older 1.96* $70,000-$100, * years 1.50* $47,000-$69, * years 1.40* $27,000-$46, * Private Insurance 1.54*

9 Model 3: Burden of Dental Care Likelihood of high financial burden due to dental care costs (n=9,831) Variable RRR Variable RRR Income Age $27,000 > 8.96* 65 and older 2.55* $27,000-$46, * years 1.78* $47,000-$69, * years 1.63* $70,000-$100, * Private Insurance 0.84* Definitions: Higher burden: 1% of total household income spent on dental care Lower burden: >0% to <1% of total household income spent on dental care

10 Province Likelihood of high financial burden due to dental care costs (n=9,831) Province Burden (RRR) NFLD 0.61* NS 0.56* NB 0.70* QB 0.76 ON 1.16 MB 0.79 AB 1.16 BC 1.09 YTN 1.23

11 Limitations No dental utilization and dental health status data available in the Statistics Canada file Spending $0 on dental care may represent the subset of the population that do not spend on dental care and also those that have excellent dental care insurance coverage

12 Key messages Middle income = Highest odds of accruing out-of-pocket expenses on dental care and also, face high financial burden Private insurance increases demand for dental care but also reduces financial burden Households in Atlantic provinces least likely to have high financial burden Seniors have the highest odds of accruing out-of-pocket expenses on dental care and also, face high financial burden

13 Canadian Population

14 Implications The projected increase in dental care demand due to demographic changes in Canada requires further debate on universal dental insurance for basic primary dental care services.
