A systematic review of the association between food insecurity and behaviours related to caries development in adults and children in high-income countries

OBJECTIVES

To synthesize and appraise the evidence regarding the relationship between food insecurity and behaviours associated with dental caries development in adults and children in high-income countries.

METHODS

A systematic review including observational studies assessing the association between food insecurity and selected dietary (free sugar consumption) and non-dietary factors (tooth brushing frequency; use of fluoridated toothpaste; dental visiting; oral hygiene aids; type of toothbrush used; interdental cleaning frequency and mouthwash use) related to dental caries development in adults and children in high-income countries. Studies specifically looking at food insecurity during the COVID-19 pandemic were excluded. Searches were performed in MEDLINE, Embase, Global Health and Scopus from inception to 25 May 2023. Two authors screened the search results, extracted data and appraised the studies independently and in duplicate. Study quality was assessed using the Newcastle-Ottawa Scale (with modifications for cross-sectional studies). Vote counting and harvest plots provided the basis for evidence synthesis.

RESULTS

Searches identified 880 references, which led to the inclusion of 71 studies with a total of 526 860 participants. The majority were cross-sectional studies, conducted in the USA and reported free sugar consumption. Evidence for the association between food insecurity and free sugar intake from 4 cohort studies and 61 cross-sectional studies including 336 585 participants was equivocal, particularly in the sugar-sweetened beverage (SSB) consumption post-hoc subgroup, where 20 out of 46 studies reported higher SSB consumption in food insecure individuals. There was consistent, but limited, evidence for reduced dental visiting in adults experiencing food insecurity compared to food secure adults from 3 cross-sectional studies including 52 173 participants. The relationship between food insecurity and dental visiting in children was less clear (3 cross-sectional studies, 138 102 participants). A single cross-sectional study of 3275 children reported an association between food insecurity and reported failure to toothbrush the previous day.

CONCLUSIONS

This review did not identify clear associations between food insecurity and behaviours commonly implicated in the development of dental caries that would explain why individuals experiencing food insecurity are more likely to have dental caries than those who have food security. There was some evidence of decreased dental visiting in adults experiencing food insecurity. Common methodological weaknesses across the evidence base related to the selection of participants or control of potentially confounding variables. Consequently, the quality of evidence for all outcomes was downgraded to very low. More research is needed to explore access to oral hygiene products and household environments conducive to habitual oral self-care in food insecure populations.

Medical Debt and the Mental Health Treatment Gap Among US Adults

Importance

Medical debt is common in the US and may hinder timely access to care for mental disorders.

Objective

To estimate the prevalence of medical debt among US adults with depression and anxiety and its association with delayed and forgone mental health care.

Design, Setting, and Participants

Cross-sectional, nationally representative survey study of US adult participants in the 2022 National Health Interview Survey who had current or lifetime diagnoses of depression or anxiety.

Exposures

Self-reported lifetime clinical diagnoses of depression and anxiety; moderate to severe symptoms of current depression (Patient Health Questionnaire-8 score ≥10) and anxiety (Generalized Anxiety Disorder-7 score ≥10) irrespective of lifetime diagnoses; and past-year medical debt.

Main Outcomes and Measures

Self-reported delaying and forgoing mental health care because of cost in the past year.

Results

Among 27 651 adults (15 050 [54.4%] female; mean [SD] age, 52.9 [18.4] years), 5186 (18.2%) reported lifetime depression, 1948 (7.3%) reported current depression, 4834 (17.7%) reported lifetime anxiety, and 1689 (6.6%) reported current anxiety. Medical debt was more common among adults with lifetime depression (19.9% vs 8.6%; adjusted prevalence ratio [aPR], 1.97; 95% CI, 1.96-1.98), lifetime anxiety (19.4% vs 8.8%; aPR, 1.91; 95% CI, 1.91-1.92), current depression (27.3% vs 9.4%; aPR, 2.34; 95% CI, 2.34-2.36), and current anxiety (26.2% vs 9.6%; aPR, 2.24; 95% CI, 2.24-2.26) compared with adults without the respective mental disorders. Medical debt was associated with delayed health care among adults with lifetime depression (29.0% vs 11.6%; aPR, 2.68; 95% CI, 2.62-2.74), lifetime anxiety (28.0% vs 11.5%; aPR, 2.45; 95% CI, 2.40-2.50), current depression (36.9% vs 17.4%; aPR, 2.25; 95% CI, 2.13-2.38), and current anxiety (38.4% vs 16.9%; aPR, 2.48; 95% CI, 2.35-2.66) compared with those without these diagnoses. Medical debt was associated with forgone health care among adults with lifetime depression (29.4% vs 10.6%; aPR, 2.66; 95% CI, 2.61-2.71), lifetime anxiety (28.2% vs 10.7%; aPR, 2.63; 95% CI, 2.57-2.68), current depression (38.0% vs 17.2%; aPR, 2.35; 95% CI, 2.23-2.48), and current anxiety (40.8% vs 17.1%; aPR, 2.57; 95% CI, 2.43-2.75) compared with those without the diagnoses.

Conclusions and Relevance

Medical debt is prevalent among adults with depression and anxiety and may contribute to the mental health treatment gap. In the absence of structural reform, new policies are warranted to protect against this financial barrier to mental health care.

Hysterectomy and medical financial hardship among U.S. women

OBJECTIVE

Hysterectomy is one of the common surgical procedures for women in the United States. Studies show that hysterectomy is associated with elevated risk of developing chronic conditions, whichmay cause financial toxicity in patients. This study aimed to assess whether women who underwent hysterectomy had a higher risk of experiencing medical financial hardship compared to women who didn't.

METHODS

Using data on 32,823 adult women from the 2019 and 2021 waves of the National Health Interview Survey, we estimated binomial and multinomial logistic regressions to assess the relationship between hysterectomy and financial hardship, defined as problems paying or unable to pay any medical bills. Further, we performed a Karlson-Holm-Breen (KHB) decomposition to examine whether the association could be explained by chronic comorbidity.

RESULTS

While the prevalence of financial hardship was 13.6 % among all women, it was 16.2 % among women who underwent a hysterectomy. The adjusted odds of experiencing medical financial hardship among women with a hysterectomy were 1.36 (95 % CI: 1.22-1.52) times that of their counterparts who did not have a hysterectomy. The KHB decomposition suggested that 34.5 % of the size of the effect was attributable to chronic conditions. Women who had a hysterectomy were also 1.45 (95 % CI: 1.26-1.67) times more likely to have unpaid medical debts.

CONCLUSIONS

Our results suggested that women, who underwent a hysterectomy in the US, were vulnerable to medical financial hardship. Policy makers and health professionals should be made aware of this issue to help women coping against this adversity.

Determinants of health poverty vulnerability in rural areas of Western China in the post-poverty relief era: an analysis based on the Anderson behavioral model

BACKGROUND

Although China has eliminated absolute poverty, the effects of sickness still pose a threat to the prospect of returning to poverty in western rural areas. However, poverty governance extends beyond solving absolute poverty, and should enhance the family's ability to resist risks, proactively identify the existence of risks, and facilitate preventive measures to reduce the probability of falling into poverty again. This study aimed to assess the health poverty vulnerability of rural households in western China and decompose its determinants.

METHODS

Based on survey data from 2022, the three-stage feasible generalized least squares method was used to calculate the health poverty vulnerability index. Then, Anderson's health behavior theory model was extended to analyse various influencing factors using binary logistic regression, and the contribution of each influencing factor was decomposed using the Shapley index. Finally, Tobit regression and the censored least absolute deviations estimation (clad) method were used to test the model's robustness.

RESULTS

A total of 5455 families in the rural Ningxia region of western China were included in the study. The health poverty vulnerability index of the sample population in 2022 was 0.3000 ± 0.2223, and families with vulnerability ≥0.5 accounted for 16.9% of the sample population. From the Anderson behavioral model, the three models including propensity, enabling, and demand factors had the best fit, and the AIC and BIC values were the smallest. The Shapley decomposition showed that the dimensions of the propensity factor, number of residents, age and educational level of the household head, and dependency ratio were the most important factors influencing vulnerability to health poverty. Tobit regression and the clad method proved the reliability of the constructed model through a robustness test.

CONCLUSION

Rural areas still face the risk of becoming poor or falling into poverty owing to residents' health problems. Health poverty alleviation should gradually change from a focus on treatment to prevention, and formulate a set of accurate and efficient intervention policies from a forward-looking perspective to consolidate the results of health poverty alleviation and prevent widescale poverty return.

The Association of Childbirth with Medical Debt in the USA, 2019-2020

BACKGROUND

Medical debt affects one in five adults in the USA and may disproportionately burden postpartum women due to pregnancy-related medical costs.

OBJECTIVE

To evaluate the association between childbirth and medical debt, and the correlates of medical debt among postpartum women, in the USA.

DESIGN

Cross-sectional.

PARTICIPANTS

We analyzed female "sample adults" 18-49 years old in the 2019-2020 National Health Interview Survey, a nationally representative household survey.

MAIN MEASURES

Our primary exposure was whether the subject gave birth in the past year. We had two family-level debt outcomes: problems paying medical bills and inability to pay medical bills. We examined the association between live birth and medical debt outcomes, unadjusted and adjusted for potential confounders in multivariable logistic regressions. Among postpartum women, we also examined the association between medical debt with maternal asthma, hypertension, and gestational diabetes and several sociodemographic factors.

KEY RESULTS

Our sample included n = 12,163 women, n = 645 with a live birth in the past year. Postpartum women were younger, more likely to have Medicaid, and lived in larger families than those not postpartum. 19.8% of postpartum women faced difficulty with medical bills versus 15.1% who were not; in multivariable regression, postpartum women had 48% higher adjusted odds of medical debt problems (95% CI 1.13, 1.92). Results were similar when examining inability to pay medical bills, and similar differences were seen for privately insured women. Among postpartum women, those with lower incomes and with asthma or gestational diabetes, but not hypertension, had significantly higher adjusted odds of medical debt problems.

CONCLUSIONS

Postpartum women experience higher levels of medical debt than other women; poorer women and those with common chronic diseases may have an even higher burden. Policies to expand and improve health coverage for this population are needed to improve maternal health and the welfare of young families.

Veterans' Experiences With Accessing Community Emergency Care

INTRODUCTION

Under current regulations, there are three separate authorities for which the Veterans Health Administration (VHA) can pay for emergency medical care received by Veterans in the community. The three VHA authorities have overlapping criteria and eligibility requirements that contribute to a complex and confusing landscape for Veterans when they obtain emergency care in the community. Given the intricacies in how VHA provides coverage for community emergency care and the desire to provide seamless Veteran-centric care, it is imperative to understand Veterans' experiences with navigating coverage for community emergency care. The purpose of this study was to elicit feedback from Veterans about their experiences with and perceptions of community emergency care coverage paid for by VHA.

MATERIALS AND METHODS

Veterans Health Administration data were used to identify geographically diverse Veterans who recently used emergency care. We conducted semi-structured, qualitative interviews with 50 Veterans to understand their VHA coverage and experiences with accessing community emergency care. Interviews were audio recorded and transcribed verbatim. We conducted directed content analysis of interview transcripts.

RESULTS

Veterans emphasized three major concerns with navigating community emergency care: (1) they lack information about benefits and eligibility when they need it most, (2) they require assistance with medical billing to avoid financial hardship and future delays in care, and (3) they desire multimodal communication about VHA policies or updates in emergency coverage.

CONCLUSIONS

Our results highlight the challenges Veterans experience in understanding VHA coverage for community emergency care. Feedback suggests that improving information, support, and communication may help Veterans make timely, informed decisions when experiencing unexpected illness or injury.

The Relationship Between Financial Worries and Psychological Distress Among U.S. Adults

This study examines the association between financial worries and psychological distress among US adults and tests its moderating effects by gender, marital status, employment status, education, and income levels. Data were derived from the cross-sectional 2018 National Health Interview Survey (NHIS) of the adult population. The hierarchical regression analysis revealed that higher financial worries were significantly associated with higher psychological distress. Additionally, the association between financial worries and psychological distress was more pronounced among the unmarried, the unemployed, lower-income households, and renters than their counterparts. The findings suggest that accessible financial counseling programs and public health intervention programs are needed to mitigate financial worries and its negative influences on overall psychological health, with greater attention devoted to vulnerable populations.

Material Hardship and Association With Sexual Risk Behavior Among Adolescent Sexual Minority Males in 3 US Cities-National HIV Behavioral Surveillance-Young Men Who Have Sex With Men, 2015

INTRODUCTION

Adolescent sexual minority males (ASMMs) are disproportionately affected by HIV relative to other youth within the United States. Social determinants of health have been explored among this population; however, economic determinants, such as material hardship, remain understudied. We examined the relationship between material hardship and sexual behavior among ASMMs aged 13-18 years residing in 3 US cities using 2015 data from CDC's National HIV Behavioral Surveillance among Young Men Who Have Sex with Men.

METHODS

Young men ages 13-18 years residing in 3 US cities were recruited through venue-based, respondent-driven, or Facebook sampling. We estimated adjusted prevalence ratios (aPRs) with 95% confidence intervals (CIs) for condomless anal intercourse (CAI) with a male sex partner in the past 12 months and with having 4 or more male sex partners in the past 12 months.

RESULTS

Of 547 ASMMs, 27% reported experiencing material hardship in the past 12 months. After adjusting for demographics, household characteristics, and city, ASMMs who experienced material hardship were more likely to report CAI with a male partner in the past 12 months (aPR: 1.55, 95% CI: 1.25 to 1.93) and to have had 4 or more male sex partners in the past 12 months (aPR: 1.44, 95% CI: 1.08 to 1.91).

DISCUSSION

More than a quarter of ASMMs experienced material hardship that was associated with increased sexual risk behavior among ASMMs. Incorporating services that address all unmet needs is important to consider for HIV prevention efforts for ASMMs.

Atherosclerotic Cardiovascular Disease, Cancer, and Financial Toxicity Among Adults in the United States

Background

Financial toxicity (FT) is a well-established side-effect of the high costs associated with cancer care. In recent years, studies have suggested that a significant proportion of those with atherosclerotic cardiovascular disease (ASCVD) experience FT and its consequences.

Objectives

This study aimed to compare FT for individuals with neither ASCVD nor cancer, ASCVD only, cancer only, and both ASCVD and cancer.

Methods

From the National Health Interview Survey, we identified adults with self-reported ASCVD and/or cancer between 2013 and 2018, stratifying results by nonelderly (age <65 years) and elderly (age ≥65 years). We defined FT if any of the following were present: any difficulty paying medical bills, high financial distress, cost-related medication nonadherence, food insecurity, and/or foregone/delayed care due to cost.

Results

The prevalence of FT was higher among those with ASCVD when compared with cancer (54% vs. 41%; p < 0.001). When studying the individual components of FT, in adjusted analyses, those with ASCVD had higher odds of any difficulty paying medical bills (odds ratio [OR]: 1.22; 95% confidence interval [CI]: 1.09 to 1.36), inability to pay bills (OR: 1.25; 95% CI: 1.04 to 1.50), cost-related medication nonadherence (OR: 1.28; 95% CI: 1.08 to 1.51), food insecurity (OR: 1.39; 95% CI: 1.17 to 1.64), and foregone/delayed care due to cost (OR: 1.17; 95% CI: 1.01 to 1.36). The presence of ≥3 of these factors was significantly higher among those with ASCVD and those with both ASCVD and cancer when compared with those with cancer (23% vs. 30% vs. 13%, respectively; p < 0.001). These results remained similar in the elderly population.

Conclusions

Our study highlights that FT is greater among patients with ASCVD compared with those with cancer, with the highest burden among those with both conditions.

The Impact of Medical Financial Hardship on Children's Health

Objective. To determine whether living in a family with medical financial hardship decreases children's access to health care. Methods. We identified children aged 4 to 17 years from the 2013 to 2018 National Health Interview Surveys. Medical financial hardship was defined as living in a family where one or more family members had problems paying medical bills in the past 12 months. Results. Of 53 483 children in the analysis, 19% were exposed to medical financial hardship. This was adversely associated with children's health status and health care use, especially greater odds of delaying care (odds ratio [OR] = 5.28; 95% confidence interval [CI] = 4.51-6.19) and having unmet health care needs (OR = 4.43; 95% CI = 4.00-4.91). Conclusions. One fifth of children live in families experiencing medical financial hardship, and this exposure is adversely correlated with child health outcomes even controlling for established measures of socioeconomic status, such as family income, health insurance coverage, and need-based program participation.

Debt, Incarceration, and Re-entry: a Scoping Review

People involved with the criminal justice system in the United States are disproportionately low-income and indebted. The experience of incarceration intensifies financial hardship, including through worsening debt. Little is known about how people who are incarcerated and their families are impacted by debt and how it affects their reentry experience. We conducted a scoping review to identify what is known about the debt burden on those who have been incarcerated and their families and how this impacts their lives. We searched 14 data bases from 1990 to 2019 for all original research addressing financial debt held by those incarcerated in the United States, and screened articles for relevance and extracted data from pertinent studies. These 31 studies selected for inclusion showed that this population is heavily burdened by debt that was accumulated in three general categories: debt directly from criminal justice involvement such as LFOs, preexisting debt that compounded during incarceration, and debts accrued during reentry for everyday survival. Debt was generally shown to have a negative effect on financial well-being, reentry, family structure, and mental health. Debts from LFOs and child support is very common among the justice-involved population and are largely unpayable. Other forms of debt likely to burden this population remain largely understudied. Extensive reform is necessary to lessen the burden of debt on the criminal justice population in order to improve reentry outcomes and quality of life.

Presence of Any Medical Debt Associated With Two Additional Years of Homelessness in a Seattle Sample

Although medical debt has been associated with housing instability, almost no research has connected homelessness to medical debt. We interviewed 60 individuals experiencing homelessness in Seattle, selected from those participating in self-governed encampments organized by a homeless advocacy organization. Most respondents reported having at least one kind of debt, with two-thirds reporting current medical debt. Almost half reported trouble paying medical bills for themselves or family members. Almost one-third believed medical debt was in part responsible for their current housing situation. More than half with medical debt incurred this debt while they were covered under insurance. People who had trouble paying medical bills experienced a more recent episode of homelessness 2 years longer than those who did not have such trouble, even after controlling for race, education, age, gender, and health status. People of color who had trouble paying medical bills reported almost 1 year more homelessness than whites.

Cumulative Burden of Financial Hardship From Medical Bills Across the Spectrum of Diabetes Mellitus and Atherosclerotic Cardiovascular Disease Among Non-Elderly Adults in the United States

Background Atherosclerotic cardiovascular disease (ASCVD) has a strong association with diabetes mellitus (DM), accounting for approximately two thirds of deaths in this patient population. Many individuals with ASCVD and DM are vulnerable to financial hardship associated with treatment-related expenses. Therefore, we examined the burden of financial hardship from medical bills across the spectrum of ASCVD status with and without DM. Methods and Results Using data from the National Health Interview Survey from 2013 to 2017, we used logistic regression analysis to examine the association of ASCVD and DM status with financial hardship and an inability to pay medical bills from a representative sample of non-elderly adults in the United States. Our study population consisted of 121 672 individuals. Approximately 3.1% of the weighted population had ASCVD, 5.6% had DM, and 1.3% had both ASCVD and DM. Nearly 50% of individuals with ASCVD and DM reported financial hardship from medical bills (23% being unable to pay medical bills at all), whereas ≈28% of those with neither ASCVD nor DM reported financial hardship from medical bills (8% being unable to pay medical bills at all). Individuals with concurrent ASCVD and DM had the highest relative odds of expressing an inability to pay at all when compared with those with neither condition (odds ratio, 2.69; 95% CI, 2.21-3.28). Conclusions Individuals with concurrent ASCVD and DM are at a disproportionately high risk of being unable to pay their medical bills. The findings provide strong evidence for developing more effective public health policies that protect vulnerable populations from financial hardship.

Burden and Consequences of Financial Hardship From Medical Bills Among Nonelderly Adults With Diabetes Mellitus in the United States

Background:

The trend of increasing total and out-of-pocket expenditure among patients with diabetes mellitus represents a risk of financial hardship for Americans and a threat to medical and nonmedical needs. We aimed to describe the national scope and associated tradeoffs of financial hardship from medical bills among nonelderly individuals with diabetes mellitus.

Methods and Results:

We used the National Health Interview Survey data from 2013 to 2017, including adults ≤64 years old with a self-reported diagnosis of diabetes mellitus. Among 164 696 surveyed individuals, 8967 adults ≤64 years old reported having diabetes mellitus, representing 13.1 million individuals annually across the United States. The mean age was 51.6 years (SD 10.3), and 49.1% were female. A total of 41.1% were part of families that reported having financial hardship from medical bills, with 15.6% reporting an inability to pay medical bills at all. In multivariate analyses, individuals who lacked insurance, were non-Hispanic black, had low income, or had high-comorbidity burden were at higher odds of being in families with financial hardship from medical bills. When comparing the graded categories of financial hardship, there was a stepwise increase in the prevalence of high financial distress, food insecurity, cost-related nonadherence, and foregone/delayed medical care, reaching 70.5%, 49.4%, 49.5%, and 74% among those unable to pay bills, respectively. Compared with those without diabetes mellitus, individuals with diabetes mellitus had higher odds of financial hardship from medical bills (adjusted odds ratio [aOR], 1.27 [95% CI, 1.18–1.36]) or any of its consequences, including high financial distress (aOR, 1.14 [95% CI, 1.05–1.24]), food insecurity (aOR, 1.27 [95% CI, 1.16–1.40]), cost-related medication nonadherence (aOR, 1.43 [95% CI, 1.30–1.57]), and foregone/delayed medical care (aOR, 1.30 [95% CI, 1.20–1.40]).

Conclusions:

Nonelderly patients with diabetes mellitus have a high prevalence of financial hardship from medical bills, with deleterious consequences.
