Oral health disparities and food insecurity in working poor Canadians

Oral health knowledge, attitudes, behaviours and status among international post-secondary students: a scoping review

Objective

This scoping review aims to review and synthesize existing literature on oral health knowledge, attitudes, behaviours, barriers, and status among international post-secondary students.

Methods

Using the Arksey and O'Malley framework, MEDLINE, Embase, Dentistry & Oral Sciences Source, CINAHL, Web of Science, and Scopus databases were searched in June 2024 for selected oral health and international student keywords. Manual searches of reference lists and citations were also conducted. Original research studies in English language were included, with no geographical or date limitations. Using Rayyan, duplicates were removed, and then two authors independently screened available literature according to eligibility criteria; inconsistencies or disagreements were resolved through a third author.

Results

The search yielded 984 articles. After removal of duplicates and those inconsistent with our inclusion criteria, 14 articles remained. In total, 13/14 articles used a cross-sectional design implementing surveys or interviews; only 4 articles presented objective clinical measures (e.g., DMFT, objective periodontal measures). Some included articles provided information about dietary habits relevant to oral health; however, information captured was limited. Overall, compared to the domestic students, international students were reported to have poorer oral health status; more gaps in their knowledge, attitudes and behaviours regarding oral health; and were also less likely to obtain routine oral health care.

Conclusion

International students may face significant challenges in managing and optimizing their oral health vs. domestic students due to various factors (e.g., acculturation stress, finances, diet, academic stress etc.). Post-secondary institutions may want to consider focusing on supporting and empowering international students to access oral health care on a regular basis through targeted interventions. To design impactful interventions, future community engaged research is needed to better understand the perspectives of international students regarding their oral health status, knowledge, attitudes, behaviours, needs, and aspirations.

Racial/Ethnicity Disparities in COVID-19 Worry for Caregivers of Adults With Intellectual and Developmental Disabilities

This study investigated the racial/ethnic differences in COVID-19-related worry amongst family caregivers of adults with intellectual and developmental disabilities (IDD) living in Texas using the COVID-Related Thoughts and Behavioral Symptoms-Adult Version (COV-TaBS-A) questionnaire. Two hundred and six caregivers completed the survey. Compared to White caregivers, Latino caregivers were more likely to be very concerned about having enough food and supplies (adj OR 3.41, 95% CI [1.50, 7.74]) when adjusting for being that sole caregiver and using provider services. In free text questions, caregivers described feeling overwhelmed by additional responsibilities, disruptions in home health services, and concerns about their loved ones' wellness. Study findings can be used to strategize support for caregivers of adults with IDD during pandemic/emergency situations.

Food insecurity and oral health in older adults

Introduction

Household food insecurity, defined as inconsistent access to sufficient food in a household, affects 1 in 15 individuals over the age of 60 years in the US. In these individuals it is associated with numerous chronic conditions, medication underuse leading to poorly controlled conditions such as diabetes and hypertension, and poor oral health. However, the relationship between food insecurity and oral health is understudied. We therefore evaluated the associations between food insecurity and aspects of oral health in older US adults.

Methods

We prospectively evaluated a subset of participants of the Health and Retirement Study (HRS) who responded to questions evaluating food insecurity in 2013 and a supplemental questionnaire regarding dental health and dental health services in 2018 (N = 472).

Results

Approximately 1 in 5 people in our study reported being food insecure in the last year. Food insecurity was correlated with poor oral health-related quality of life scores and more tooth loss. Individuals who were food insecure reported worse self-rated oral health (OR = 2.67), greater odds of losing 8 or more teeth (OR = 2.35), and lower odds of receiving oral care (OR = 0.60) compared to their food secure peers.

Conclusions

Though individuals experiencing food insecurity were likely to have more unmet oral health needs than their peers, they were less likely to seek dental care. To improve the oral health status of this group, in addition to making oral health care more accessible, it may also be necessary to address the social and environmental factors preventing these people from seeking oral health care.

Exploring the Link between Xerostomia and Oral Health in Mental Illness: Insights from Autism Spectrum Disorder, Depression, Bipolar Disorder, and Schizophrenia

BACKGROUND

The relationship between mental disorders and oral health is complex, involving behavioral, biological, and psychosocial factors. This review aims to investigate the impact of mental disorders, including autism spectrum disorder (ASD), depression, bipolar disorder, and schizophrenia, on oral health outcomes.

METHODS

A comprehensive review of existing literature was conducted to analyze the oral health outcomes associated with each mental disorder. The focus was on examining dietary habits, oral hygiene behaviors, physiological changes, and medication side effects that contribute to oral health issues.

RESULTS

The findings indicate that individuals with ASD often exhibit unique dietary habits and reduced oral hygiene capabilities due to sensory sensitivities, leading to a higher prevalence of dental caries and periodontal diseases. Depression and bipolar disorder are associated with physiological changes such as reduced saliva production and poor oral hygiene behaviors, increasing the risk of oral health problems. Medications used for these conditions exacerbate issues like xerostomia, further elevating the risk of dental diseases. Schizophrenia poses additional challenges, including cognitive impairments and medication side effects that hinder effective oral care, heightening susceptibility to oral diseases.

CONCLUSIONS

This review highlights the specific oral health challenges associated with different mental disorders and emphasizes the need for tailored dental care strategies that integrate mental health considerations. The study contributes to the literature by demonstrating the unique oral health impacts of these disorders. However, the findings are limited by the scope of available cross-sectional data and the absence of longitudinal studies. Future research should focus on longitudinal and intervention-based studies to explore causal relationships and develop effective treatments.

Imbalances in the oral health workforce: a Canadian population-based study

BACKGROUND

In Canada, a new federal public dental insurance plan, being phased in over 2022-2025, may help enhance financial access to dental services. However, as in many other countries, evidence is limited on the supply and distribution of human resources for oral health (HROH) to meet increasing population needs. This national observational study aimed to quantify occupational, geographical, institutional, and gender imbalances in the Canadian dental workforce to help inform benchmarking of HROH capacity for improving service coverage.

METHODS

Sourcing microdata from the 2021 Canadian population census, we described workforce imbalances for three groups of postsecondary-qualified dental professionals: dentists, dental hygienists and therapists, and dental assistants. To assess geographic maldistribution relative to population, we linked the person-level census data to the geocoded Index of Remoteness for all inhabited communities. To assess gender-based inequities in the dental labour market, we performed Blinder-Oaxaca decompositions for examining differences in professional earnings of women and men.

RESULTS

The census data tallied 3.4 active dentists aged 25-54 per 10,000 population, supported by an allied workforce of 1.7 dental hygienists/therapists and 1.6 dental assistants for every dentist. All three professional groups were overrepresented in heavily urbanized communities compared with more rural and remote areas. Almost all dental service providers worked in ambulatory care settings, except for male dental assistants. The dentistry workforce was found to have achieved gender parity numerically, but women dentists still earned 21% less on average than men, adjusting for other characteristics. Despite women representing 97% of dental hygienists/therapists, they earned 26% less on average than men, a significant difference that was largely unexplained in the decomposition analysis.

CONCLUSIONS

Accelerating universal coverage of oral healthcare services is increasingly advocated as an integral, but often neglected, component toward achieving the health-related Sustainable Development Goals. In the Canadian context of universal coverage for medical (but not dentistry) services, the oral health workforce was found to be demarcated by considerable geographic and gendered imbalances. More cross-nationally comparable research is needed to inform innovative approaches for equity-oriented HROH planning and financing, often critically overlooked in public policy for health systems strengthening.

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.

Food insecurity and the dental team: a pilot study to explore opinions

PURPOSE

In total, 17% of UK households with children experience food insecurity, with evidence to suggest a direct correlation with the prevalence of oral disease. This study explores current perceptions of the dental team, when recognising and supporting families who may experience food insecurity.

MATERIALS AND METHODS

An online, anonymous cross-sectional survey was designed and sent to members of the British Society of Paediatric Dentistry (BSPD) in June 2023, examining confidence and understanding surrounding food insecurity and dental health. Quantitative data is presented descriptively and qualitative data using a thematic analysis.

RESULTS

The response rate was 9.6% (n = 76). A significant number recognise the link between poor oral health and food insecurity, 80.3% (n = 61). Although practitioners are confident in oral health counselling, 80.3% (n = 61) a smaller proportion are not as confident when approaching food insecurity 32.9% (n = 25). Dental team members recognise the need to improve identification of affected patients and that they have a professional duty to support. Intervention strategies, such as additional training to support team development and signposting of patients are indicated.

CONCLUSION

This study suggests that whilst dental professionals understand the link between food insecurity and oral health, and their responsibilities to those affected; they lack confidence in identifying such patients and providing support. Additional conversations and training are fundamental to better understand their role, which must reflect the needs of the population that they serve.

Food Insecurity in the Elective Enhanced Recovery After Surgery Colorectal Surgical Population: Prevalence and Implications for Surgical Outcomes

BACKGROUND

Food insecurity is defined as having limited or uncertain availability of nutritionally adequate food. Approximately 10.5% of U.S. households are food-insecure. Our study aimed to determine the prevalence and postoperative implications of food insecurity in a diverse group of colorectal surgery patients admitted to a hospital in an area with a higher-than-average median income.

METHODS

The 6-question Household Food Security Survey was added to the colorectal surgery ERAS program preoperative paperwork. Patient demographics, comorbidities, operative parameters, length of stay, and postoperative outcomes were collected by review of electronic medical records.

RESULTS

A total of 294 ERAS patients (88.8%) completed the survey over an 11-month period. Thirty-three patients (11.2%) were identified as food-insecure. Food-insecure patients were more likely to be non-white (P = .003), younger (P = .009), smokers (P = .004), chronic narcotic users (P < .001), unmarried (P = .007), and have more comorbidities (P = .004). The food-insecure population had more frequent postoperative ileus (P = .044). Hospital length of stay was significantly longer in food-insecure patients (8.6 days vs 5.4 days, P < .001). Food-insecure patients also had higher rates of >30-day mortality (P = .049).

DISCUSSION

Food insecurity was found to occur in patients that lived in communities deemed both affluent and distressed. These patients had longer hospital stays and higher mortality. A food insecurity questionnaire can easily identify patients at risk. Further investigations to mitigate these complications are warranted.

The association between the supplemental nutrition assistance programme participation and dental caries among U.S. adults

INTRODUCTION

The Supplemental Nutrition Assistance Programme (SNAP) is a federal programme aimed to alleviate hunger and improve food insecurity. The impact of SNAP participation on overall health has been studied. However, little is known about the effects of SNAP participation on oral health. We aimed to investigate the association between participating in SNAP and dental caries and to explore the role of food insecurity as a moderator in this relationship.

METHODS

We obtained data from the National Health and Nutrition Examination Survey (NHANES) cycles 2011-2012 and 2013-2014.The primary outcome was untreated dental caries (none vs. one or more). Self-reported SNAP participation status in the past 12 months was the predictor, and food security was the moderator. Food security was measured as overall food security status (full food secure/ food insecure) and household-level food security (full, marginal, low and very low). Bivariate and multiple logistic regression analyses were conducted to evaluate the relationship between SNAP and dental caries, and whether food insecurity moderates this relationship. Statistical analysis was carried out in September 2020.

RESULTS

Our results suggested that after adjusting for potential confounders, SNAP participants were more likely to have untreated dental caries than non-SNAP participants (odds ratio: 1.6; 95% CI: 1.2-2.0). Food security status did not alter the relationship between SNAP participation and untreated dental caries.

CONCLUSIONS

Food security status did not alter the relationship between SNAP participation and untreated dental caries. SNAP participation was associated with untreated dental caries among U.S. adults, and this was not affected by their food security status.

Burden of dental caries in individuals experiencing food insecurity: a systematic review and meta-analysis

CONTEXT

Food insecurity affects approximately 2.37 billion people worldwide. Individuals experiencing food insecurity are more likely to exhibit poor health-related endpoints. Dental caries, a highly prevalent noncommunicable disease, is modulated by an interplay between biological, behavioral, and environmental factors.

OBJECTIVE

This systematic review and meta-analysis aimed to assess whether individuals experiencing food insecurity were more likely to exhibit dental caries than individuals facing food security.

DATA SOURCES

The Web of Science, PubMed, Scopus, Embase, Ovid, CINAHL, LILACS, and APA PsycINFO databases were checked from inception to November 2021. Grey literature and Google Scholar were also examined. An updated search was conducted in August 2022. Observational studies were included if they evaluated the association between dental caries and food insecurity status.

DATA EXTRACTION

Data extraction was performed by two reviewers.

DATA ANALYSIS

Random-effects meta-analyses were conducted using R language. In total, 514 references were retrieved from databases, of which 14 articles were included in qualitative synthesis and 7 were merged into meta-analysis. The results of an inverse-variance meta-analysis (OR = 1.62; 95%CI, 1.01-2.60) and a meta-analysis of binary data (OR = 1.66; 95%CI, 1.36-2.02) demonstrated that food-insecure individuals were more likely to exhibit dental caries than food-secure individuals. Inverse-variance meta-analyses appraising multiple strata of food security also showed that individuals experiencing marginal food security (OR = 1.48; 95%CI, 1.28-1.72), individuals experiencing low food security (OR = 1.26; 95%CI, 1.01-1.57), and those experiencing very low food security (OR = 1.33; 95%CI, 1.04-1.71) were more likely to exhibit dental caries than individuals experiencing full food security.

CONCLUSION

Dental caries is associated with food insecurity. Individuals living with food insecurity are more likely to exhibit dental caries than those who have food security.

A Pilot Study Exploring Practices that Support the Longevity of Community Gardens Supported by Religious Organizations

Current food production methods in the United States (US) contribute to environmental degradation as well as food insecurity. Food production by means of community gardens has the potential to reduce the deleterious effects of current production methods. However, many community gardens face challenges that hinder their longevity, thereby reducing the likelihood of the support they might provide for environmentally sustainable food production and decreased food insecurity for community members. Researchers conducted a literature review regarding best practices for community gardens, and used ethnographic research methods to inform a culturo-behavioral systems analysis using the Total Performance System and matrix (systems interdependency) analysis to better understand the cultural practices of two established community gardens in the southwest region of the US. The results of the analyses are presented in terms of recommendations to support each community garden's sustainability. Recommendations regarding future research include environmental manipulations to identify functional relations and potential outcome measures for improving the longevity of community gardens.

A Study on the Relationship between Food Security and the Number of Remaining Teeth in Korean Adults: The Korea National Health and Nutrition Examination Survey (KNHANES VII), 2016-2018

Food security is important for human health and quality of life. This study investigated the association between food security and the number of remaining teeth in Korean adults. Raw data from the Korea National Health and Nutrition Examination Survey (KNHANES) VII (2016-2018) were analyzed, including data from 13,199 adults aged 19 years or older. The associations between food security and number of teeth were assessed using multiple multinomial logistic regression models after adjusting for demographic and health factors as covariates. In the model adjusted for all socioeconomic, medical, and behavior variables, the odds ratio of tooth loss (16-20 teeth) was 3.80 (95% confidence interval [CI] 1.56-9.21) in the group of people that reported often feeling insecurity regarding various food groups compared to those who reported feeling food security. The results of this study demonstrated an association between food security and the number of remaining teeth in Korean adults. Therefore, food security is essential for improving lifelong oral health.

Food Insecurity in Israeli Elderly is Associated with Sociodemographic Characteristics, Disability, and Depression: Policy Implications

Background

Food insecurity (FI) and poor health can turn into a vicious cycle with detrimental effects, especially in the elderly, however, few studies have examined the relationship between FI and health in this age group.

Objectives

We investigated associations of FI with physical and mental health and health behaviors among community-dwelling elderly.

Methods

We used nationally representative, cross-sectional data from the 2014-2015 Israel National Health and Nutrition Survey of the Elderly (Rav Mabat Zahav) on FI, sociodemographic characteristics, noncommunicable diseases (NCDs), disability, self-assessed physical, oral, and mental health for 1006 individuals aged ≥65 y.

Results

FI affected 12.3% of all households with elderly and was significantly higher among late immigrants and Arabs. Bivariate associations of FI with the number of NCDs, depression, disability in all 6 domains (vision, hearing, mobility, self-care, remembering, communication), poor self-assessed physical and oral health, chewing and swallowing problems, feelings of loneliness, insufficient physical activity, and smoking were significant (P < 0.05). In a multivariable logistic regression controlling for population group, household size, age and sex, FI was significantly associated (P < 0.05) with lack of formal education (OR: 6.26; 95% CI: 1.66, 23.65), being in the lowest (OR: 23.56; 95% CI: 3.71, 149.76) or second-lowest (OR: 16.75; 95% CI: 2.68, 104.52) per capita household income quartile, having one (OR: 2.11; 95% CI: 1.05, 4.23) or several disabilities (OR: 4.04; 95% CI: 1.72, 9.45), and having ever been diagnosed with depression (OR: 3.34; 95% CI: 1.35, 8.28).

Conclusions

FI is associated with physical and mental health problems, multiple disabilities, and loneliness among Israeli elderly. Providing income support could reduce FI, and subsidized congregate and home-delivered meal services could be expanded to meet the needs of elderly with disabilities and counter social isolation. Because low education, disability, and depression are particularly prevalent among the food insecure and vulnerable groups face language barriers, assistance with applications for these services should be increased.

Food insecurity is associated with self-reported oral health in school-age Ecuadorian children and is mediated by dietary and non-dietary factors

OBJECTIVE

The main objective was to investigate the association of household food insecurity (HFI) with child oral health. A secondary objective was to explore potential dietary and non-dietary mediators of the HFI-child oral health relationship.

DESIGN

Cross-sectional data from the nationally representative Ecuadorian National Health and Nutrition Survey (2018) were analysed. The data included self-reported child oral health, HFI (Food Insecurity Experience Scale), diet (FFQ) and oral care behaviours (toothbrushing frequency, toothpaste use). The association of HFI with the reported number of oral health problems was examined with stereotype logistic regression. Parallel mediation analysis was used to explore potential dietary (highly fermentable carbohydrate foods, plain water) and non-dietary (toothbrushing) mediators of the HFI-oral health relationship. Bias-corrected standard errors and 95 % CI were obtained using non-parametric bootstrapping (10 000 repetitions). Effect size was measured by percent mediation (PM).

SETTING

Ecuador.

PARTICIPANTS

5-17-year-old children (n 23 261).

RESULTS

HFI affected 23 % of child households. 38·5 % of children have at least one oral health problem. HFI was associated with a greater number of oral health problems: 1-2 problems (adjusted odds ratio (AOR) = 1·37; 95 % CI (1·15, 1·58); P = 0·0001), 3-4 problems (AOR = 2·21; 95 % CI (1·98, 2·44); P = 0·0001), 5-6 problems (AOR = 2·57; 95 % CI (2·27, 2·88); P = 0·0001). The HFI-oral health relationship was partially mediated by highly fermentable carbohydrate foods (PM = 4·3 %), plain water (PM = 1·8 %) and toothbrushing frequency (PM = 3·3 %).

CONCLUSIONS

HFI was associated with poorer child oral health. The HFI-oral health relationship was partially mediated by dietary and non-dietary factors. Longitudinal studies are needed to replicate our findings and investigate the role of other potential mediators.

The Emergence of Precarious Employment as a Determinant of Health in Europe and the Relevance of Contextual Factors: A Critical Research Synthesis

Precarious employment as a determinant of health remains on the rise in Europe, in contrast to the European Pillar of Social Rights. Research in epidemiology, public health, and occupational health research has debated the health impacts of precarious employment. A number of studies have concluded that precarious employment contributes to poor health. More recent research has focused on the contextual influences of the association between precarious employment and health. Accordingly, we argue that the welfare state and the specific institutional arrangements on the national level determine and mediate the extent of the association between precarious employment and health. This research synthesis: (a) debates explanations for the rise of precarious employment in Europe, (b) illustrates how precarious employment has risen in Europe since the 1980s, (c) indicates empirical findings of the association between precarious employment and health in Europe, (d) discusses how research explains between-country differences of the association between precarious employment and health, and (e) presents empirical findings on the contextual determinants of the association between precarious employment and health in Europe.

Food insecurity, home ownership and income-related equity in dental care use and access: the case of Canada

Background

It has been documented that income is a strong determinant of dental care use in Canada, mostly due to the lack of public coverage for dental care. We assess the contributions of food insecurity and home ownership to income-related equity in dental care use and access. We add to the literature by adding these two variables among other socio-economic determinants of equity in dental care use and access to dental care. Evidence on equity in access to and use of dental care in Canada can inform policymaking.

Methods

We estimate income-related horizontal inequity indexes for the probability of 1) receiving at least one dental visit in the last 12 months; and 2) lack of dental visits during the 3 years before the interview. We conduct the analyses using data from the 2013–2014 Canadian Community Health Survey (CCHS) at the national and regional level.

Results

There is pro-rich inequity in the probability of visiting a dentist or an orthodontist and in access to dental care in Ontario. Inequities vary across jurisdictions. Housing tenure and food insecurity contribute importantly to both use of and access to dental care, adding information not captured by standard socio-economic determinants.

Conclusions

Redistributing income may not be enough to reduce inequities. Careful monitoring of equity in dental care is needed together with interventions targeting fragile groups not only in terms of income but also in improving house and food security.

Chronic pain and depressive symptoms are related to food insecurity among urban food bank users

BACKGROUND

Food bank users suffer high food insecurity. Food insecurity increases risk for chronic health conditions. However, chronic pain and its relation to food insecurity among food bank users is unknown. Knowledge about populations with chronic pain is important to direct appropriate public health nutritional strategies.

METHODS

Participants completed a survey including sleep, pain, depressive symptoms and food insecurity measures. Descriptive statistics characterized the burden of chronic pain among the sample, and a series of chi-square and t-tests assessed for demographic differences between food bank users who reported pain compared to those who did not. Logistic regression tested for variables predicting food insecurity.

RESULTS

Within the sample (N = 207), 53% reported a chronic pain diagnosis. Adults with pain were more likely to receive food stamps and to have a mental health condition than those without pain. Regression analyses revealed that depressive symptoms and chronic pain significantly predicted food insecurity when controlling for age and gender.

CONCLUSIONS

Exploring the link between depression, pain and nutritional resources may enhance understanding of causal relationships driving food insecurity. Public health officials should address nutritional needs of adults including those with chronic pain who use food bank services.

The association between food insecurity and dental caries among U.S. adults: Data from the National Health and Nutrition Examination survey

OBJECTIVES

The purpose of this study was to examine the association between food insecurity and untreated dental caries using a nationally representative sample of US adults.

METHODS

Data from the National Health and Nutrition Examination Survey (NHANES) cycles 2011-2012 and 2013-2014 on adults aged 18 years and older were analysed (n = 10 723). Primary predictors were overall food security (food-secure/ food-insecure) and household food security (full, marginal, low and very low). The main outcome was any untreated dental caries (none/ ≥ one). Multiple logistic regression analyses were done to estimate the adjusted odds ratio after controlling for confounders.

RESULTS

Food-insecure adults were more likely to have untreated dental caries than food-secure adults after adjusting for potential confounders (OR: 1.2; 95% CI: 0.9-1.5). Adults from households with marginal (OR:1.4; 95% CI:1.5-2.2), low (OR:1.3, 95% CI:1.3-2.0) and very low food security (OR:1.3; 95% CI:0.9-1.5) had higher odds of untreated caries than adults from households with full food security. Following age stratification, marginal, low and very low food-secure adults had higher prevalence of untreated dental caries than full food-secure adults across all age groups.

CONCLUSIONS

Our findings suggest that food-insecure adults had higher odds of untreated dental caries than food-secure adults. These findings highlight the importance of assessing food insecurity as a risk factor for dental caries. Longitudinal cohort studies are recommended to determine causal mechanisms.

Biocultural pathways linking periodontal disease expression to food insecurity, immune dysregulation, and nutrition

OBJECTIVES

In this article, we test theoretical pathways leading to and resulting from periodontal disease to better understand how periodontal disease, which is measurable in both past and present populations, integrates biocultural context and affects whole-body physiology.

METHODS

We use data from the National Health and Nutrition Examination Survey (NHANES) 2003-2004 and logistic and linear regressions to test pathways linking psychosocial stress to periodontal disease, and periodontal disease to serum vitamin C levels. We then use causal mediation analysis to test the role of mediating variables in these pathways (n = 1853 individuals).

RESULTS

Food insecurity was positively associated with periodontal disease and negatively associated with serum counts of C-reactive protein (CRP) and neutrophils. Neither CRP nor neutrophils significantly mediated the relationship between food insecurity and periodontal disease. Periodontal disease was negatively associated with serum vitamin C levels and positively associated with neutrophil counts. Neutrophils may mediate the relationship between periodontal disease and vitamin C.

CONCLUSIONS

We identify two main findings: (a) periodontal disease contributes to and may result from immune dysregulation, particularly of neutrophils, and (b) an immune response to chronic infection such as periodontal disease is metabolically expensive for the body to maintain and likely depletes serum micronutrient levels. Both micronutrient status and serum neutrophil counts affect multiple skeletal and physiological phenotypes and thus position periodontal disease in whole-body context.

Narrative review of affinities and differences between the social determinants of oral and general health in Canada: establishing a common agenda

BACKGROUND

This article overviews Canadian work on the social determinants of oral and general health noting their affinities and differences.

METHODS

A literature search identified Canadian journal articles addressing the social determinants of oral health and/or oral health inequalities. Analysis identified affinities and differences with six themes in the general social determinants of health literature.

RESULTS

While most Canadian social determinants activity focuses on physical and mental health there is a growing literature on oral health-literature reviews, empirical studies and policy analyses-with many affinities to the broader literature. In addition, since Canada provides physical and mental health services on a universal basis, but does not do so for dental care, there is a special concern with the reasons behind, and the health effects-oral, physical and mental-of the absence of publicly financed dental care.

CONCLUSIONS

The affinities between the social determinants of oral health and the broader social determinants of health literature suggests the value of establishing a common research and action agenda. This would involve collaborative research into common social determinants of oral and general health and combined policy advocacy efforts to improve Canadians' living and working conditions as means of achieving health for all.

Availability and affordability of healthy and less healthy food in Nova Scotia: where you shop may affect the availability and price of healthy food

OBJECTIVE

The present study aimed to examine the availability and price of healthier compared with less healthy foods by geography, store category and store type for convenience stores, and by store size for grocery stores in Nova Scotia.

DESIGN

A cross-sectional study that examined differences in the overall availability and price of healthier compared to less healthy foods in grocery and convenience stores in Nova Scotia. The Nova Scotia Consumer Food Environment project was part of a larger initiative of the Nova Scotia government (Department of Health and Wellness) to assess the food and beverage environment in Nova Scotia in 2015/16.

SETTING

Four geographic zones (Nova Scotia Health Authority Management Zones) in Nova Scotia, Canada.

PARTICIPANTS

A sample of forty-seven grocery stores and fifty-nine convenience stores were selected from a list of 210 grocery stores and 758 convenience stores in Nova Scotia to ensure geographic and store type representation in our sample.

RESULTS

Findings indicate that rurality had a significant effect on food availability as measured by the Nutrition Environment Measures Surveys (NEMS) score (P < 0·01); there was a higher availability of healthy foods in rural compared to urban areas for convenience stores but not grocery stores. Healthier foods were also more available in chain stores compared to independent stores (P < 0·01) and in large stores compared to small and medium stores (P < 0·001 and P < 0·01, respectively).

CONCLUSIONS

The availability of and accessibility to less healthy foods in Nova Scotia food environment suggests that there is a need for government policy action to support a food environment that contributes to healthier diets.

Household food insecurity and dental caries in Korean adults

OBJECTIVE

Food security is important to health maintenance and disease prevention. The aim of this study was to identify the association between household food insecurity and dental caries in Korean adults.

METHOD

Data from 14 770 adults included in the 2013-2015 Korea National Health and Nutritional Survey were analysed. Household food insecurity was evaluated using the 18-item US Household Food Security/Hunger Survey Module. General characteristics differences based on household food security were compared with weighted one-way analysis of variance for continuous variables and weighted chi-squared tests for categorical variables. A modified Poisson approach was used to calculate prevalence ratios and 95% confidence intervals (95% CIs).

RESULTS

The prevalence of untreated dental caries in permanent teeth was 28.9% (CI;27.6, 30.2), 36.7% (33.0, 40.5) and 48.9% (40.0, 57.8) among individuals with household food security, household food insecurity without hunger and household food insecurity with hunger, respectively. Relative to those who were food-secure, the prevalence ratios (95% CIs) for dental caries were 1.12 (0.97-1.31) and 1.35 (1.02-1.80) for those with household food insecurity without and with hunger, respectively, adjusting for age, sex, body mass index, socioeconomic status, life style, dietary and dental factors.

CONCLUSION

We found that household food insecurity is associated with prevalence of untreated dental caries in Korean adults. Healthcare providers ought to consider the important role that food security can play in the prevention and management of oral health in adults.

Food Insecurity in Advanced Capitalist Nations: A Review

Food insecurity is a substantial problem in nearly every advanced capitalist nation, with sizable portions of residents in many affluent countries struggling to eat healthily every day. Over time, a very large literature has developed that documents food insecurity, evaluates programs meant to reduce that insecurity, and proposes solutions to attenuate the problem. The purpose of the current review is to provide a very broad overview of the food insecurity literature, including definitions, measurement, areas of study, and impacts on health. Importantly, this review suggests there are two major causes of food insecurity in the advanced nations: economic inequality and neoliberalism. The food insecurity literature suggests that diminished government responsibility in advanced capitalist nations corresponds to an increase in feeding programs run by non-profit and charitable organizations. This review concludes by suggesting that, while a massive amount of research on food insecurity currently exists, more research is still needed to address gaps in the literature when it comes to significant events, coping strategies and disadvantaged populations.

Dentistry's social contract is at risk

BACKGROUND

The implications of the social contract for medicine and those it serves has been debated by bioethicists, political scientists, and physicians. Far less attention, however, has been given to dentistry's social contract.

METHODS

The existing literature from medicine is used to explore the social contract and the role of dentistry in today's society, focusing on several areas of interest.

RESULTS

The authors' analysis discusses the history of the social contract and its implications for professionalism. The authors examine the failure of the dental profession to adequately address population needs and inequities in oral health, situating this in the context of an increasingly commodified, commercialized, cosmetically oriented, and proprietary culture in the profession. The authors highlight the important role of organized dentistry in facilitating change and renewing the social contract.

CONCLUSIONS

The authors conclude that reforms are necessary for dentistry to remain a profession.

PRACTICAL IMPLICATIONS

The authors' findings may inform oral health policies and underscore the need for change among dental providers and organized dentistry to maintain dentistry's professional status.

Health Inequities and the Shifting Paradigms of Food Security, Food Insecurity, and Food Sovereignty

Global hunger, food insecurity, and malnutrition are on the rise, partly resulting in furthering health inequities between classes and groups of peoples among and within countries. A systematic understanding of the links between inequities in food politics and health issues is a challenge, and it is partly complicated by the presence of 3 contending and shifting paradigms in food politics, namely, food security, food insecurity, and food sovereignty. These paradigms suggest competing views as to the causes of and solutions to hunger, food insecurity, and malnutrition. We argue that food sovereignty offers a better alternative for understanding and responding to food issues in relation to the challenge of tackling health inequities. However, the ways in which and the degree to which the issues of health inequities are incorporated in the current narratives and practices of food sovereignty is rather thin, and vice versa. Our concluding argument is that an interactive dialogue in research and social actions between food sovereignty, on the one hand, and health inequity, on the other hand, can mutually enrich and strengthen both fields of research and spheres of social actions.

Patient preferences on sharing private information in dental settings

BACKGROUND

The authors conducted a study to understand patients' preferences and comfort levels in discussing personal medical, behavioral, and social information with their oral health care providers.

METHODS

A self-report survey was completed by US adults 18 years and older (N = 387) using Amazon Mechanical Turk, an online research portal for survey-based research. The survey assessed comfort discussing demographics, physical health, behavioral health, oral health, and living conditions with oral health providers.

RESULTS

Factor analysis suggested that participants were comfortable discussing demographics and standard dental questions but were less comfortable answering questions about trauma, stress, coping, and living and behavioral patterns. Demographics did not predict comfort with disclosure, and many participants did not feel personal information was relevant to oral health care.

CONCLUSIONS

Community education efforts can focus on helping patients understand how oral health is related to behavioral health and social conditions.

PRACTICAL IMPLICATIONS

Dental education should focus on helping oral health care providers communicate comfortably around these topics, balancing education with respect for a patient's willingness to disclose.

Household food insecurity, dental caries and oral-health-related quality of life in Brazilian Indigenous adults

Food insecurity is a complex phenomenon that affects the health and wellbeing of vulnerable families. The aim of this study was to investigate the relationship between household food insecurity, dental caries, oral health-related quality of life, and social determinants of health among Indigenous adults. A cross-sectional study was conducted among Kaingang adults aged 35-44 years old from the Guarita Indigenous Land, Brazil. Food insecurity was assessed through the EBIA scale. Dental caries was assessed using the DMFT index. Participants answered the OHIP-14 questionnaire and a structured interview. Descriptive and multivariate analyzes using Poisson regression models were performed. The final sample included 107 adults from 97 households. Approximately 95% lived in food insecure families. Severe food insecurity was present in 58% of the households. The phenomenon was associated to the Bolsa Família benefit, household size, and greater perception of oral health impacts on quality of life. The high number of families affected by food insecurity reveals the social vulnerability of the Kaingang people. Food insecurity in Kaingangs adults is associated to oral health perception and social determinants of health.

Independent associations and effect modification between lifetime substance use and recent mood disorder diagnosis with household food insecurity

Poor mental health and substance use are associated with food insecurity, however, their potential combined effects have not been studied. This study explored independent associations and effect modification between lifetime substance use and mood disorder in relation to food insecurity. Poisson regression analysis of data from British Columbia respondents (n = 13,450; 12 years+) in the 2007/08 Canadian Community Health Survey was conducted. Measures included The Household Food Security Survey Module (7.3% food insecure), recent diagnosis of a mood disorder (self-reported; 9.5%), lifetime use of cannabis, cocaine/crack, ecstasy, hallucinogens, and speed, any lifetime substance use, sociodemographic covariates, and the interaction terms of mood disorder by substance. For those with recent diagnosis of a mood disorder the prevalence of lifetime substance use ranged between 1.2 to 5.7% and were significantly higher than those without recent mood disorder diagnosis or lifetime use of substances (p’s < 0.05). For respondents with a recent mood disorder diagnosis or who used cannabis, food insecurity prevalence was higher compared to the general sample (p < 0.001); prevalence was lower for cocaine/crack use (p < 0.05). Significant effect modification was found between mood disorder with cannabis, ecstasy, hallucinogen and any substance use over the lifetime (PRs 0.51 to 0.64, p’s 0.022 to 0.001). Independent associations were found for cocaine/crack and speed use (PRs 1.68, p’s < 0.001) and mood disorder (PRs 2.02, p’s < 0.001). Based on these findings and the existing literature, future study about coping and resilience in the context of substance use, mental health, and food insecurity may lead to the development of relevant interventions aimed at mental well-being and food security.

Social Determinants of Pediatric Oral Health

Social determinants of health are defined as conditions in which people are born and live and the role these conditions play on health outcomes. Research indicates that risk factors and their interactions are far more complex than originally thought. This article outlines social determinant constructs and their role in understanding oral health promotion. Due to the complex interactions, oral health must be promoted using a multilevel chronic disease model or common risk factor approach. An understanding of social determinants is particularly important for the pediatric population because optimum oral health and general health in adulthood are heavily influenced by childhood.

Food Insecurity And Health Outcomes

Almost fifty million people are food insecure in the United States, which makes food insecurity one of the nation's leading health and nutrition issues. We examine recent research evidence of the health consequences of food insecurity for children, nonsenior adults, and seniors in the United States. For context, we first provide an overview of how food insecurity is measured in the country, followed by a presentation of recent trends in the prevalence of food insecurity. Then we present a survey of selected recent research that examined the association between food insecurity and health outcomes. We show that the literature has consistently found food insecurity to be negatively associated with health. For example, after confounding risk factors were controlled for, studies found that food-insecure children are at least twice as likely to report being in fair or poor health and at least 1.4 times more likely to have asthma, compared to food-secure children; and food-insecure seniors have limitations in activities of daily living comparable to those of food-secure seniors fourteen years older. The Supplemental Nutrition Assistance Program (SNAP) substantially reduces the prevalence of food insecurity and thus is critical to reducing negative health outcomes.

Association of Household Food Insecurity with the Mental and Physical Health of Low-Income Urban Ecuadorian Women with Children

Chronic physical and mental health conditions account for a rising proportion of morbidity, mortality, and disability in the Americas region. Household food insecurity (HFI) has been linked to chronic disease in US and Canadian women but it is uncertain if the same is true for low- and middle-income Latin American countries in epidemiologic transition. We conducted a survey to investigate the association of HFI with the physical and mental health of 794 women with children living in low-income Quito, Ecuador, neighborhoods. Data were collected on HFI and health indicators including self-reported health (SF-1), mental health (MHI-5), blood pressure, and self-reported mental and physical health complaints. Fasting blood glucose and lipids were measured in a subsample. The multivariate analyses revealed that HFI was associated with poorer self-rated health, low MHI-5 scores, and mental health complaints including stress, depression, and ethnospecific illnesses. It was also associated with chest tightness/discomfort/pain, dental disease, and gastrointestinal illness but not other conditions. The findings suggest that improving food security in low-income households may help reduce the burden of mental distress in women with children. The hypothesized link with diabetes and hypertension may become more apparent as Ecuador moves further along in the epidemiologic transition.

Dutch food bank parcels do not meet nutritional guidelines for a healthy diet

Nutritional intakes of food bank recipients and consequently their health status largely rely on the availability and quality of donated food in provided food parcels. In this cross-sectional study, the nutritional quality of ninety-six individual food parcels was assessed and compared with the Dutch nutritional guidelines for a healthy diet. Furthermore, we assessed how food bank recipients use the contents of the food parcel. Therefore, 251 Dutch food bank recipients from eleven food banks throughout the Netherlands filled out a general questionnaire. The provided amounts of energy (19 849 (sd 162 615) kJ (4744 (sd 38 866) kcal)), protein (14·6 energy percentages (en%)) and SFA (12·9 en%) in a single-person food parcel for one single day were higher than the nutritional guidelines, whereas the provided amounts of fruits (97 (sd 1441) g) and fish (23 (sd 640) g) were lower. The number of days for which macronutrients, fruits, vegetables and fish were provided for a single-person food parcel ranged from 1·2 (fruits) to 11·3 (protein) d. Of the participants, only 9·5 % bought fruits and 4·6 % bought fish to supplement the food parcel, 39·4 % used all foods provided and 75·7 % were (very) satisfied with the contents of the food parcel. Our study shows that the nutritional content of food parcels provided by Dutch food banks is not in line with the nutritional guidelines. Improving the quality of the parcels is likely to positively impact the dietary intake of this vulnerable population subgroup.

Association between untreated dental caries and household food insecurity in schoolchildren

Abstract The aim of the present study was to assess the association between untreated dental caries (UDC) and household food insecurity (HFI) among schoolchildren in different income strata. A population-based study was carried out with a sample of 584 12-y-old schoolchildren. Oral examinations were performed and HFI was determined using a validated scale. Other independent variables were analyzed for being of interest to the stratification of the results (per capita household income) or for acting as potential confounding variables. The prevalence of UDC and HFI was 45% and 39%, respectively. The multivariate models demonstrated that the UDC was significantly more prevalent among children in food-insecure households with per capita income of up to US$ 70.71 than among those in the same income stratum that were free of HFI [PR = 1.52 (95%CI = 1.01-2.29)]. HFI was associated with a greater frequency of UDC among low-income schoolchildren, but had no significant impact on this variable among children from other income strata. Thus, ensuring access to quality food may be a good strategy for minimizing inequities in oral health and reducing dental caries experience among schoolchildren from low-income families.

Food Insecurity: A Concept Analysis

AIM

To report an analysis of the concept of food insecurity in order to (a) propose a theoretical model of food insecurity useful to nursing; and (b) discuss its implications for nursing practice, nursing research, and health promotion.

BACKGROUND

A total of 48 million Americans are food insecure. As food insecurity is associated with multiple negative health effects, nursing intervention is warranted.

DESIGN

Concept analysis.

DATA SOURCES

A literature search was conducted in May 2014 in Scopus and MEDLINE using the exploded term "food insecur*." No year limit was placed. Government websites and popular media were searched to ensure a full understanding of the concept.

REVIEW METHODS

Iterative analysis, using the Walker and Avant method.

RESULTS

Food insecurity is defined by uncertain ability or inability to procure food, inability to procure enough food, being unable to live a healthy life, and feeling unsatisfied. A proposed theoretical model of food insecurity, adapted from the Socio-Ecological Model, identifies three layers of food insecurity (individual, community, society), with potential for nursing impact at each level.

CONCLUSION

Nurses must work to fight food insecurity. There exists a potential for nursing impact that is currently unrealized. Nursing impact can be guided by a new conceptual model, Food Insecurity Within the Nursing Paradigm.

Association between household food insecurity and annual health care costs

BACKGROUND

Household food insecurity, a measure of income-related problems of food access, is growing in Canada and is tightly linked to poorer health status. We examined the association between household food insecurity status and annual health care costs.

METHODS

We obtained data for 67 033 people aged 18-64 years in Ontario who participated in the Canadian Community Health Survey in 2005, 2007/08 or 2009/10 to assess their household food insecurity status in the 12 months before the survey interview. We linked these data with administrative health care data to determine individuals' direct health care costs during the same 12-month period.

RESULTS

Total health care costs and mean costs for inpatient hospital care, emergency department visits, physician services, same-day surgeries, home care services and prescription drugs covered by the Ontario Drug Benefit Program rose systematically with increasing severity of household food insecurity. Compared with total annual health care costs in food-secure households, adjusted annual costs were 16% ($235) higher in households with marginal food insecurity (95% confidence interval [CI] 10%-23% [$141-$334]), 32% ($455) higher in households with moderate food insecurity (95% CI 25%-39% [$361-$553]) and 76% ($1092) higher in households with severe food insecurity (95% CI 65%-88% [$934-$1260]). When costs of prescription drugs covered by the Ontario Drug Benefit Program were included, the adjusted annual costs were 23% higher in households with marginal food insecurity (95% CI 16%-31%), 49% higher in those with moderate food insecurity (95% CI 41%-57%) and 121% higher in those with severe food insecurity (95% CI 107%-136%).

INTERPRETATION

Household food insecurity was a robust predictor of health care utilization and costs incurred by working-age adults, independent of other social determinants of health. Policy interventions at the provincial or federal level designed to reduce household food insecurity could offset considerable public expenditures in health care.

Food insecurity among Dutch food bank recipients: a cross-sectional study

OBJECTIVE

To determine the prevalence of (very) low food security among Dutch food bank recipients, and to identify potential demographic, lifestyle and nutrition-related factors associated with (very) low food security.

SETTING

11 of 135 Dutch food banks were selected throughout the Netherlands.

PARTICIPANTS

251 Dutch food bank recipients participated in the study (93 men and 158 women). Inclusion criteria for participation were: (1) at least 18 years of age, (2) sufficiently fluent in Dutch to participate in oral and written interviews, (3) recipient of a Dutch food bank for at least 1 month and (4) collect own food parcel at the food bank. A single member per household was included.

PRIMARY OUTCOME

Level of food security.

RESULTS

The prevalence of food insecurity was 72.9% (N=183), of which 40.4% (N=74) reported very low food security. Of the very low food secure participants, 56.8% (N=42) reported they were ever hungry but did not eat because they could not afford enough food in the previous 3 months. Adjusted multinomial logistic regression analyses showed that households without children were less likely to experience low food security (OR 0.39 (95% CI 0.18 to 0.88)) and men (OR 0.24 (95% CI 0.11 to 0.51)) were less likely to experience very low food security, while low-educated recipients (OR 5.05 (95% CI 1.37 to 18.61)) were more likely to experience very low food security. Furthermore, recipients with high satisfaction with overall food intake (OR 0.46 (95% CI 0.27 to 0.78)), high perceived healthiness of overall food intake (OR 0.34 (95% CI 0.19 to 0.62)) or high self-efficacy of eating healthy (OR 0.62 (95% CI 0.40 to 0.96)) were less likely to experience very low food security.

CONCLUSIONS

Our study showed high prevalence rates of food insecurity among Dutch food bank recipients, and identified subgroups at increased risk of food insecurity. More research is urgently needed on the underlying determinants of food insecurity and the effectiveness of food assistance by food banks.

When working is not enough: food insecurity in the Canadian labour force

OBJECTIVE

Food insecurity, lack of access to food due to financial constraints, is highly associated with poor health outcomes. Households dependent on social assistance are at increased risk of experiencing food insecurity, but food insecurity has also been reported in households reporting their main source of income from employment/wages (working households). The objective of the present study was to examine the correlates of food insecurity among households reliant on employment income.

DESIGN

Working households reporting food insecurity were studied through analysis of the Canadian Community Health Survey, 2007-2008, employing descriptive statistics and logistic regression. Food insecurity was measured using the Household Food Security Survey Module; all provinces participated.

SETTING

Canada.

SUBJECTS

Canadian households where main income was derived through labour force participation. Social assistance recipients were excluded.

RESULTS

For the period 2007-2008, 4% of working households reported food insecurity. Canadian households reliant on primary earners with less education and lower incomes were significantly more likely to experience food insecurity; these differences were accentuated across some industry sectors. Residence in Quebec was protective. Working households experiencing food insecurity were more likely to include earners reporting multiples jobs and higher job stress. Visible minority workers with comparable education levels experienced higher rates of food insecurity than European-origin workers.

CONCLUSIONS

Reliance on employment income does not eliminate food insecurity for a significant proportion of households, and disproportionately so for households with racialized minority workers. Increases in work stress may increase the susceptibility to poor health outcomes of workers residing in households reporting food insecurity.

Chronic physical and mental health conditions among adults may increase vulnerability to household food insecurity

Analyses of cross-sectional population survey data in Canada and the United States have indicated that household food insecurity is associated with poorer self-rated health and multiple chronic conditions. The causal inference has been that household food insecurity contributes to poorer health, but there has been little consideration of how adults' health status may relate to households' vulnerability to food insecurity. Our objectives were to examine how the presence of an adult with one or more chronic physical or mental health conditions affects the odds of a household being food insecure and how the chronic ill-health of an adult within a food-insecure household affects the severity of that household's food insecurity. Using household- and respondent-level data available for 77,053 adults aged 18-64 y from the 2007-2008 Canadian Community Health Survey, we applied logistic regression analyses, controlling for household sociodemographic characteristics, to examine the association between health and household food insecurity. Most chronic conditions increased the odds of household food insecurity independent of household sociodemographic characteristics. Compared with adults with no chronic condition, the odds of household food insecurity were 1.43 (95% CI: 1.28, 1.59), 1.86 (95% CI: 1.62, 2.14), and 3.44 (95% CI: 3.02, 3.93) for adults with 1, 2, and 3 or more chronic conditions, respectively. Among food-insecure households, adults with multiple chronic conditions had higher odds of severe household food insecurity than adults with no chronic condition. The chronic ill-health of adults may render their households more vulnerable to food insecurity. This has important practice implications for health professionals who can identify and assist those at risk, but it also suggests that appropriate chronic disease management may reduce the prevalence and severity of food insecurity.

Nurse's Desk: food bank-based outreach and screening to decrease unmet referral needs

The Nurse's Desk health screening project used the Intervention Wheel model to conduct outreach, screening, education, and referral for food bank clients (n = 506). Blood glucose, blood pressure, health care utilization, and unmet referral needs were assessed. Screening results identified 318 clients (62.8%) with 1 or more unmet referral needs, including 6 clients (3.16%) with capillary blood glucose more than 199 mg/dL and 132 (31.9%) with hypertension. Clients had higher-than-average systolic and diastolic blood pressures and undiagnosed diabetes than in the general population. A client-approved method for tracking completed referrals is needed for this potentially high-risk population.

Severity of household food insecurity is sensitive to change in household income and employment status among low-income families

Cross-sectional studies have established a relationship between poverty and food insecurity, but little is known about the acute changes within households that lead to changes in food insecurity. This study examined how changes in income, employment status, and receipt of welfare related to change in severity of food insecurity during 1 y among low-income families. In 2005-2007, 501 families living in market and subsidized rental housing were recruited through door-to-door sampling in high-poverty neighborhoods in Toronto. One year later, families were re-interviewed. The final longitudinal analytic sample included 331 families. Within-household change in income, employment, and welfare receipt were examined in relation to change in severity of food insecurity. Severity was denoted by the aggregate raw score on the Household Food Security Survey Module (HFSSM). Analyses were stratified by housing subsidy status owing to differences in characteristics between households. Food insecurity was a persistent problem among families; 68% were food insecure at both interviews. Severity was dynamic, however, as 73.4% answered more or fewer questions affirmatively on the HFFSM between baseline and follow-up. Among market-rent families, a $2000 gain in income during the year and gain of full-time employment were associated with a 0.29 and 1.33 decrease in raw score, respectively (P < 0.01). This study suggests that improvements in income and employment are related to improvements in families' experiences of food insecurity, highlighting the potential for income- and employment-based policy interventions to affect the severity of household food insecurity for low-income families.
