A diet high in fruits and vegetables (FV) is associated with reduced risk of chronic disease. One strategy to incentivize FV consumption among low-income households is to make them more affordable through the Supplemental Nutrition Assistance Program (SNAP). This study aims to identify the cost effectiveness of subsidizing FV purchases among the one in seven Americans who participate in SNAP. A cost-effectiveness analysis was conducted from a societal perspective to estimate lifetime costs and health gains associated with subsidizing FV purchases. A stochastic microsimulation model of obesity, type 2 diabetes, myocardial infarction, and stroke in the 2015 U.S. population was used. Model parameters were based on nationally representative SNAP participation and dietary consumption data from the National Health and Nutrition Examination Survey (2003-2012), and data from a randomized trial of FV subsidies among SNAP users. Despite cycling of participants in and out of SNAP, expanding an FV subsidy nationwide through SNAP would be expected to reduce incidence of type 2 diabetes by 1.7% (95% CI=1.2, 2.2), myocardial infarction by 1.4% (95% CI=0.9, 1.9), stroke by 1.2% (95% CI=0.8, 1.6), and obesity by 0.2% (95% CI=0.1, 0.3), and be cost saving from a societal perspective. The saved costs would be largely attributable to long-term reductions in type 2 diabetes and cardiovascular diseases. The model suggests nationwide SNAP FV subsidies would reduce chronic disease morbidity, mortality, and costs over long time horizons that are unlikely to be observed in short-term community-based trials.

OBJECTIVE: Previous randomized trials found that treating periodontitis improved glycemic control in patients with type 2 diabetes (T2D), thus lowering the risks of developing T2D-related microvascular diseases and cardiovascular disease (CVD). Some payers in the U.S. have started covering nonsurgical periodontal treatment for those with chronic conditions, such as diabetes. We sought to identify the cost-effectiveness of expanding periodontal treatment coverage among patients with T2D. RESEARCH DESIGN AND METHODS: A cost-effectiveness analysis was conducted to estimate lifetime costs and health gains using a stochastic microsimulation model of oral health conditions, T2D, T2D-related microvascular diseases, and CVD of the U.S. population. Model parameters were obtained from the nationally representative National Health and Nutrition Examination Survey (NHANES) (2009–2014) and randomized trials of periodontal treatment among patients with T2D. RESULTS: Expanding periodontal treatment coverage among patients with T2D and periodontitis would be expected to avert tooth loss by 34.1% (95% CI −39.9, −26.5) and microvascular diseases by 20.5% (95% CI −31.2, −9.1), 17.7% (95% CI −32.7, −4.7), and 18.4% (95% CI −34.5, −3.5) for nephropathy, neuropathy, and retinopathy, respectively. Providing periodontal treatment to the target population would be cost saving from a health care perspective at a total net savings of $5,904 (95% CI −6,039, −5,769) with an estimated gain of 0.6 quality-adjusted life years per capita (95% CI 0.5, 0.6). CONCLUSIONS: Providing nonsurgical periodontal treatment to patients with T2D and periodontitis would be expected to significantly reduce tooth loss and T2D-related microvascular diseases via improved glycemic control. Encouraging patients with T2D and poor oral health conditions to receive periodontal treatment would improve health outcomes and still be cost saving or cost-effective.

Purpose: We aim to understand the impact of the COVID-19 on health care utilization and oral health conditions of patients at federally qualified health centers (FQHCs), where patients are disproportionately low income, publicly insured, or uninsured. Methods: Using deidentified electronic health records of patients at FQHCs in the United States from January 2019 through December 2020 ( n = 431,509), variations in health care utilization since the COVID-19 outbreak were observed by procedure types and patient characteristics. Changes in dental utilization and oral health conditions were characterized using mixed-effect negative binomial and logistic regression models. Results: Dental utilization decreased more drastically than medical utilization during shelter-in-place periods in 2020 and rebounded more slowly after the reopening. Greater demands for oral surgery and teledentistry and less demands for preventive services were observed in 2020. As compared to 2019, patients experienced more psychological stress–related dental conditions with odds ratios of 1.52 (95% confidence interval [CI], 1.31–1.76) for uninsured, 1.48 (95% CI, 1.07–2.02) for Medicaid enrollees, and 2.38 (95% CI, 1.68–3.40) for private insurance beneficiaries. Conclusion: As a result of COVID-19, patients received more invasive dental procedures due to delayed treatment and experienced a higher risk of psychological stress–related dental conditions. Continued support for statewide policies to expand access to oral health care and oral health promotion strategies for the vulnerable populations would be encouraged. Knowledge Transfer Statement: Our study describes the impact of COVID-19 on dental care use and oral health conditions at Federally Qualified Health Centers, targeted to provide care for some of the most vulnerable populations in the United States. The results of this retrospective cohort study can be used by clinicians and policymakers on understanding the clinical needs of the vulnerable populations after the pandemic. It highlights the need for continued support to expand access to oral health care and oral health promotion to these populations.

Unemployment rates in the United States are rapidly increasing as a result of the COVID-19 pandemic and attendant economic disruption. As employees lose their jobs, many will lose their employer-sponsored dental insurance (ESDI). Changes in insurance coverage are directly related to the oral health of the population, with many at risk of losing access to dental care. We assessed the impact of recent unemployment rates on insurance coverage and dental utilization. We estimated changes in dental insurance coverage at the state level, using previously applied econometric estimates. Expected changes in types of dental procedures performed at dental practices nationwide were assessed using a microsimulation model, using national practice survey data. Changes in emergency department (ED) visits for dental problems were estimated by fitting trendlines to ED visit patterns by payer type. Sensitivity analyses were conducted to assess how variations in unemployment rates and rates of ESDI in response to unemployment could alter the results. Since March 2020, the national unemployment rate has increased by 8.40 percentage points, an increase expected to result in more than 16 million individuals losing ESDI in the United States. Of these individuals, 45.0% are likely to enroll in their state’s Medicaid and Children’s Health Insurance Program, and 47.0% are expected to become uninsured. With these expected changes in dental insurance coverage, the average dental practice would experience decreases in routine checkup visits but increases in tooth extraction, a procedure that is highly used by publicly insured or uninsured patients. In addition, dental-related ED visits would be expected to grow by 4.0%. Losses of employment caused by the COVID-19 in the United States can have countervailing effects on people’s health by impeding access to dental care. Lack of dental insurance is expected to be more pronounced in states that have not expanded Medicaid or do not provide Medicaid dental benefits for adults.

Tooth decay (caries) is the most common chronic disease among US children yet is often neglected, leading to substantial decreases in children’s quality of life and up to 10 million missed school days.1,2 Dental care is one of the greatest unmet children’s health needs, with wide racial and ethnic disparities existing among racially and ethnically minoritized populations, such as American Indian, Asian, Black, Hispanic, Hawaiian and Pacific Islander communities.3 Despite efforts to increase dental care utilization among minoritized populations, large oral health disparities remain, with Black and Hispanic children having the poorest oral health of any racial or ethnic groups in the US.4-7 In addition to lack of access to recommended care, individual health behaviors and community-related structural factors also contribute to the high risk of tooth decay in minoritized populations.5,8

Background. The National Salt Reduction Initiative, in which food producers agree to lower sodium to levels deemed feasible for different foods, is expected to significantly reduce sodium intake if expanded to a large sector of food manufacturers. Objective. Given recent data on the relationship between sodium intake, hypertension, and associated cardiovascular disease at a population level, we sought to examine risks and benefits of the program. Design. To estimate the impact of further expanding the initiative on hypertension, myocardial infarction (MI) and stroke incidence, and related mortality, given food consumption patterns across the United States, we developed and validated a stochastic microsimulation model of hypertension, MI, and stroke morbidity and mortality, using data from food producers on sodium reduction among foods, linked to 24-hour dietary recalls, blood pressure, and cardiovascular histories from the National Health and Nutrition Examination Survey. Results. Expansion of the initiative to ensure all restaurants and manufacturers reach agreed-upon sodium targets would be expected to avert from 0.9 to 3.0 MIs (a 1.6%–5.4% reduction) and 0.5 to 2.8 strokes (a 1.1%–6.2% reduction) per 10,000 Americans per year over the next decade, after incorporating consumption patterns and variations in the effect of sodium reduction on blood pressure among different demographic groups. Even high levels of consumer addition of table salt or substitution among food categories would be unlikely to neutralize this benefit. However, if recent epidemiological associations between very low sodium and increased mortality are causal, then older women may be at risk of increased mortality from excessively low sodium intake. Conclusions: An expanded National Salt Reduction Initiative is likely to significantly reduce hypertension and hypertension-related cardiovascular morbidity but may be accompanied by potential risks to older women.
