Oral health disparities and food insecurity in working poor Canadians

Associations between area-level disadvantage and DMFT among a birth cohort of Indigenous Australians

BACKGROUND

Individual-level factors influence DMFT, but little is known about the influence of community environment. This study examined associations between community-level influences and DMFT among a birth cohort of Indigenous Australians aged 16-20 years.

METHODS

Data were collected as part of Wave 3 of the Aboriginal Birth Cohort study. Fifteen community areas were established and the sample comprised 442 individuals. The outcome variable was mean DMFT with explanatory variables including diet and community disadvantage (access to services, infrastructure and communications). Data were analysed using multilevel regression modelling.

RESULTS

In a null model, 13.8% of the total variance in mean DMFT was between community areas, which increased to 14.3% after adjusting for gender, age and diet. Addition of the community disadvantage variable decreased the variance between areas by 4.8%, indicating that community disadvantage explained one-third of the area-level variance. Residents of under-resourced communities had significantly higher mean DMFT (β = 3.86, 95% CI 0.02, 7.70) after adjusting for gender, age and diet.

CONCLUSIONS

Living in under-resourced communities was associated with greater DMFT among this disadvantaged population, indicating that policies aiming to reduce oral health-related inequalities among vulnerable groups may benefit from taking into account factors external to individual-level influences.

[Socioeconomic status, toothbrushing frequency, and health-related behaviors in adolescents: an analysis using the PeNSE database]

This study investigated the association between oral and general health-related behaviors and socioeconomic status, and the relationship between health-related behaviors and toothbrushing among adolescents. The database used here was the National School-Based Health Survey (PeNSE), a cross-sectional population-based study in 2009 with students from 27 Brazilian State capitals. Socio-demographic and health-related behavior data were collected. The survey included 49,189 adolescents (47.5% males), the majority of whom were 14 years of age and enrolled in public schools. The associations between toothbrushing frequency and other health-related behaviors and socioeconomic status varied between boys and girls. Associations were observed between health-related habits and toothbrushing frequency in both sexes, but with variations according to socioeconomic status. Planning health promotion interventions for adolescents should take their individual characteristics and family and social context into account.

Is accessing dental care becoming more difficult? Evidence from Canada's middle-income population

Objective

To explore trends in access to dental care among middle-income Canadians.

Methods

A secondary data analysis of six Canadian surveys that collected information on dental insurance coverage, cost-barriers to dental care, and out-of-pocket expenditures for dental care was conducted for select years from 1978 to 2009. Descriptive analyses were used to outline and compare trends among middle-income Canadians with other levels of income as well as national averages.

Results

By 2009, middle-income Canadians had the lowest levels of dental insurance coverage (48.7%) compared to all other income groups. They reported the greatest increase in cost-barriers to dental care, from 12.6% in 1996 to 34.1% by 2009. Middle-income Canadians had the largest rise in out-of-pocket expenditures for dental care since 1978.

Conclusions

This study suggests that affordability issues in accessing dental care are no longer just a problem for the lowest income groups in Canada, but are now impacting middle-income earners as a consequence of their lack of, or decreased access to, comprehensive dental insurance.

Gender-stratified models to examine the relationship between financial hardship and self-reported oral health for older US men and women

OBJECTIVES

We evaluated the relationship between financial hardship and self-reported oral health for older men and women.

METHODS

We focused on adults in the 2008 Health and Retirement Study (n = 1,359). The predictor variables were 4 financial hardship indicators. We used Poisson regression models to estimate the prevalence ratio of poor self-reported oral health.

RESULTS

In the non-gender-stratified model, number of financial hardships was not significantly associated with self-reported oral health. Food insecurity was associated with a 12% greater prevalence of poor self-reported oral health (95% confidence interval [CI] = 1.04, 1.21). In the gender-stratified models, women with 3 or more financial hardships had a 24% greater prevalence of poor self-reported oral health than women with zero (95% CI = 1.09, 1.40). Number of hardships was not associated with self-reported oral health for men. For men, skipping medications was associated with 50% lower prevalence of poor self-reported oral health (95% CI = 0.32, 0.76).

CONCLUSIONS

Number of financial hardships was differentially associated with self-reported oral health for older men and women. Most financial hardship indicators affected both genders similarly. Future interventions to improve vulnerable older adults' oral health should account for gender-based heterogeneity in financial hardship experiences.

Food insecurity is an ongoing national concern

Food insecurity is a leading public health challenge in the United States today. This is primarily due to the magnitude of the problem, ∼50 million persons are food insecure (i.e., they were uncertain of having, or unable to acquire, enough food because they had insufficient money or other resources), and the serious negative health and other outcomes associated with being food insecure. This paper defines the measure used to delineate whether a household is food insecure. The measure, the Core Food Security Module, is based on 18 questions about a household's food situation. From the responses, a household is defined as food secure, low food secure, or very low food secure, with the latter 2 categories defined as "food insecure." I next discuss the extent of food insecurity in the US across various dimensions and the key determinants of food insecurity. The key policy tool used to address food insecurity is the Supplemental Nutrition Assistance Program (SNAP; formerly known as the Food Stamp Program). During the current economic downturn, >40 million persons are enrolled in SNAP, with total benefits of >$70 billion. This makes it the largest food assistance program and the largest near-cash assistance program in the US. After defining the eligibility criteria, I review the literature, which has demonstrated the effectiveness of SNAP in addressing its key goal, namely the alleviation of food insecurity in the US. I conclude with 4 suggestions for how SNAP can maintain and even improve its effectiveness in alleviating food insecurity.

Health insurance, socio-economic position and racial disparities in preventive dental visits in South Africa

This study sought to determine the contributions of socio-economic position and health insurance enrollment in explaining racial disparities in preventive dental visits (PDVs) among South Africans. Data on the dentate adult population participating in the last South African Demographic and Health Survey conducted during 2003–2004 (n = 6,312) was used. Main outcome measure: Reporting making routine yearly PDVs as a preventive measure. Education, material wealth index and nutritional status indicated socio-economic position. Multi-level logistic regression analysis was conducted to determine the predictors of PDVs. A variant of Blinder-Oaxaca decomposition analysis was also conducted. Health insurance coverage was most common among Whites (70%) and least common among black Africans (10.1%) in South Africa. Similarly, a yearly PDV was most frequently reported by Whites (27.8%) and least frequently reported among black Africans (3.1%). Lower education and lower material wealth were associated with lower odds of making PDVs. There was significant interaction between location (urban/rural) and education (p = 0.010). The racial and socio-economic differences in PDVs observed in urban areas were not observed in rural areas. In the general dentate population, having health insurance significantly increased the odds of making PDVs (OR = 4.32; 3.04–6.14) and accounted for 40.3% of the White/non-White gap in the probability of making PDVs. Overall, socio-economic position and health insurance enrollments together accounted for 55.9% (95% CI = 44.9–67.8) of the White/non-White gap in PDVs. Interventions directed at improving both socio-economic position and insurance coverage of non-White South Africans are likely to significantly reduce racial disparities in PDVs.

Public preferences for government spending in Canada

This study considers three questions: 1. What are the Canadian public’s prioritization preferences for new government spending on a range of public health-related goods outside the scope of the country’s national system of health insurance? 2. How homogenous or heterogeneous is the Canadian public in terms of these preferences? 3. What factors are predictive of the Canadian public’s preferences for new government spending? Data were collected in 2008 from a national random sample of Canadian adults through a telephone interview survey (n =1,005). Respondents were asked to rank five spending priorities in terms of their preference for new government spending. Bivariate and multivariable logistic regression analyses were conducted. As a first priority, Canadian adults prefer spending on child care (26.2%), followed by pharmacare (23.1%), dental care (20.8%), home care (17.2%), and vision care (12.7%). Sociodemographic characteristics predict spending preferences, based on the social position and needs of respondents. Policy leaders need to give fair consideration to public preferences in priority setting approaches in order to ensure that public health-related goods are distributed in a manner that best suits population needs.

Financial management skills are associated with food insecurity in a sample of households with children in the United States

Food insecurity is one of the leading public health challenges facing children in the United States today. Reducing food insecurity and its attendant consequences requires an understanding of the determinants of food insecurity. Although previous work has greatly advanced our understanding of these determinants, the role of one of the oft-speculated important determinants of food insecurity, household financial management skills, has not been considered. To address this research lacuna, we use a recently conducted survey, the Survey of Household Finances and Childhood Obesity, that has information on specific financial management practices, impressions of financial management skills, and households' food insecurity. The sample included 904 households with children. Within this sample, 19.3% were food insecure and, for our central financial management skill variable, the mean value was 3.55 on a 5-point scale. Probit regression models estimated the probability of a household being food insecure as conditional on financial management skills and other covariates. We found a large and significant inverse relationship between a respondent's use of specific financial management practices and food insecurity and between a respondent's confidence in his or her financial management skills and food insecurity. That is, households with greater financial management abilities are less likely to be food insecure. This finding also holds when the sample is restricted to households with incomes <200% of the poverty line. These results suggest that improving households' financial management skills has the potential to reduce food insecurity in the United States.

Government spending on dental care: is it a public priority?

OBJECTIVES

The majority of Canadians believe that the government should play some role in providing dental care within Canada's health care system. However, it is unclear whether Canadians consider this as a top public priority. This study determines whether dental care is a public priority among Canadian adults relative to other policy concerns and identifies factors predictive of a first priority ranking for dental care.

METHODS

Data were collected in 2008 from a national random sample of 1,005 Canadian adults through a telephone interview survey. Respondents were asked to rank five spending priorities (dental care, pharmacare, home care, vision care, and child care) in terms of preferences for new government spending. Simple descriptive analyses were undertaken based on sociodemographic characteristics. Logistic regression modeling was conducted to determine which factors are predictive of a first priority ranking for dental care.

RESULTS

Comparatively, dental care stands as the third choice among the other spending priority areas. Approximately 21 percent of adults consider dental care a first priority for spending. First priority ranking of dental care appears to be linked to socioeconomic factors: household income, educational attainment, and dental insurance coverage.

CONCLUSIONS

As a public priority, a moderate level of demand exists for more government spending on dental care in Canada, specifically among those of low income, low educational attainment, and who lack dental insurance coverage. A sustained effort should be made to push forward public dental care policies that target priority population subgroups.

Access to dental care for low-income adults: perceptions of affordability, availability and acceptability

The objective of this study was to explore access to dental care for low-income communities from the perspectives of low-income people, dentists and related health and social service-providers. The case study included 60 interviews involving, low-income adults (N = 41), dentists (N = 6) and health and social service-providers (N = 13). The analysis explores perceptions of need, evidence of unmet needs, and three dimensions of access--affordability, availability and acceptability. The study describes the sometimes poor fit between private dental practice and the public oral health needs of low-income individuals. Dentists and low-income patients alike explained how the current model of private dental practice and fee-for-service payments do not work well because of patients' concerns about the cost of dentistry, dentists' reluctance to treat this population, and the cultural incompatibility of most private practices to the needs of low-income communities. There is a poor fit between private practice dentistry, public dental benefits and the oral health needs of low-income communities, and other responses are needed to address the multiple dimensions of access to dentistry, including community dental clinics sensitive to the special needs of low-income people.

Income, dental insurance coverage, and financial barriers to dental care among Canadian adults

OBJECTIVES

To explore the issue of affordability in dental care by assessing associations between income, dental insurance, and financial barriers to dental care in Canadian adults.

METHODS

Data were collection from a national sample of adults 18 years and over using a telephone interview survey based on random digit dialing. Questions were asked about household income and dental insurance coverage along with three questions concerning cost barriers to accessing dental care. These were: "In the past three years...has the cost of dental care been a financial burden to you?...have you delayed or avoided going to a dentist because of the cost?...have you been unable to have all of the treatment recommended by your dentist because of the cost?"

RESULTS

The survey was completed by 2,027 people, over half of which (56.0%) were covered by private dental insurance and 4.9 percent by public dental programs. The remainder, 39.1 percent, paid for dental care out-of-pocket. Only 19.3 percent of the lowest income group had private coverage compared with 80.5 percent of the highest income group (P < 0.001). Half (48.2%) responded positively to at least one of the three questions concerning cost barriers, and 14.8 percent responded positively to all three. Low income subjects (P < 0.001) and those without dental insurance (P < 0.001) were most likely to report financial barriers to care. While private dental insurance reduced financial barriers to dental care, it did not entirely eliminate it, particularly for those with low incomes. Those reporting such barriers visited the dentist less frequently and had poorer oral health outcomes after controlling for the effects of income and insurance coverage.

CONCLUSIONS

Canadian adults report financial barriers to dental care, especially those of low income. These barriers appear to have negative effects with respect to dental visiting and oral health outcomes. For policy, appropriateness will be key, as clarity needs to be established in terms of what constitutes actual need, and thus which dental services can then be considered a public health response to affordability.

Equity in dental care among Canadian households

BACKGROUND

Changes in third party financing, whether public or private, are linked to a household's ability to access dental care. By removing costs at point of purchase, changes in financing influence the need to reach into one's pocket, thus facilitating or limiting access. This study asks: How have historical changes in dental care financing influenced household out-of-pocket expenditures for dental care in Canada?

METHODS

This is a mixed methods study, comprised of an historical review of Canada's dental care market and an econometric analysis of household out-of-pocket expenditures for dental care.

RESULTS

We demonstrate that changes in financing have important implications for out-of-pocket expenditures: with more financing come drops in the amount a household has to spend, and with less financing come increases. Low- and middle-income households appear to be most sensitive to changes in financing.

CONCLUSIONS

Alleviating the price barrier to care is a fundamental part of improving equity in dental care in Canada. How people have historically spent money on dental care highlights important gaps in Canadian dental care policy.
