RESUMEN
BACKGROUND: Current measures of food insecurity focus on economic access to food, but not on the physical aspect of food insecurity that captures the inability to access food or prepare meals. This is particularly relevant among the older adult population who are at a high risk of functional impairments. OBJECTIVES: To develop a short-form physical food security (PFS) tool among older adults using statistical methods based on the Item Response Theory (Rasch) model. METHODS: Pooled data from adults aged ≥60 y of the NHANES (2013-2018) (n = 5892) were used. The PFS tool was derived from the physical limitation questions included in the physical functioning questionnaire of NHANES. Item severity parameters, fit and reliability statistics, and residual correlation between items were estimated using the Rasch model. The construct validity of the tool was assessed by examining associations with the Healthy Eating Index (HEI)-2015 scores, self-reported health, self-reported diet quality, and economic food insecurity, using weighted multivariable linear regression analysis, controlling for potential confounders. RESULTS: A 6-item scale was developed, which had adequate fit statistics and high reliability (0.62). It was categorized based on raw score severity into high, marginal, low, and very low PFS. Very low PFS was associated with respondent's self-reported poor health (OR = 23.8; 95% CI: 15.3, 36.9; P < 0.0001), self-reported poor diet (OR = 3.9; 95% CI: 2.8, 5.5; P < 0.0001), low and very low economic food security (OR = 6.08; 95% CI: 4.23, 8.76; P < 0.0001), and with lower mean HEI-2015 index score, in comparison to older adults with high PFS (54.5 compared with 57.5, P = 0.022). CONCLUSIONS: The proposed 6-item PFS scale captures a new dimension of food insecurity that can inform on how older adults experience food insecurity. The tool will require further testing and evaluation in larger and different contexts to demonstrate its external validity.

BACKGROUND: Economic food insecurity tools are used to detect need for assistance in the general population. However, in older adults, food insecurity can also be due to factors other than economic, such as physical inability to shop or cook. OBJECTIVES: We determined: 1) the proportion of older adults in the United States who experience physical and/or economic food insecurity; 2) differences in characteristics, diet quality, chronic conditions, and depression by economic and/or physical food insecurity; and 3) the relation of physical and economic food insecurity with diet quality and with depression. METHODS: Data from adults aged ≥60 y of the NHANES (2013-2018) were used. Groups were created based on economic food security [measured using the USDA's Household Food Security Survey Module (HFSSM)] and physical food security (measured using questions evaluating ability to shop and cook). Depression, Healthy Eating Index (HEI-2015) score, and socioeconomic characteristics were compared by food security group. Rao-Scott χ2 tests were used to test for significant differences between categorical variables, and t tests for continuous variables. Associations between food security status, HEI-2015, and depression score were examined using linear regression analysis. RESULTS: One-quarter (25.0%) of older adults had physical difficulty accessing food but were not living in economically food insecure households. Those who lived in economically food insecure households and also had physical difficulties accessing food had the lowest mean HEI-2015 score (51.7) and highest mean depression score (6.9); both were significantly lower than the mean scores of those who lived in food secure households (HEI-2015 = 57.3; depression = 2.1; P < 0.01). CONCLUSIONS: Considering physical ability to shop for and prepare food when measuring food insecurity in older adults can help identify those who might need dietary and mental health support the most, and those who need food assistance but would otherwise be missed if only measuring economic access.

OBJECTIVES: (1) To examine total quality of foods consumed on the day a home-delivered meal (HDM) of the Older Americans Act Nutrition Program (OAANSP) was served, and when a HDM was not served; and (2) to estimate proportion of HDM participants and non-participants meeting the daily average recommendations for guidance-based foods and nutrients. DESIGN: Cross-sectional study. SETTING: Data were obtained from the national 2015-2017 Outcomes Evaluation Study of HDM participants in the USA. PARTICIPANTS: Adults aged 67 years and older (n 1227), 620 HDM recipients and 607 matching non-participants examined in three groups: (1) meal recipients who received a HDM on the day of the 24-h dietary recall; (2) no-meal recipients who did not receive a HDM on the day of the recall and (3) matching HDM non-participants. RESULTS: Healthy Eating Index (HEI)-2010 scores of HDM participants were significantly lower on the day the meal was not received compared with when a meal was received (52·5 v. 63·4, P < 0·0001). There was no significant difference in the total HEI-2010 scores of HDM meal recipients and HDM non-participants. Despite the meal, less than 20 % of HDM participants and non-participants met the 2010-Diet Guidelines for Americans recommended average daily intake for fruit, vegetables, dairy, protein foods and solid fats. CONCLUSION: HDM participants' diet quality is poorer when they do not receive a meal putting them at increased risk of malnutrition. Expanding the OAANSP to offer meals on weekends and/or to include more than one meal/d is recommended to improve the diet of this vulnerable population.
RESUMEN
OBJECTIVES: To examine: (1) diet quality of older adults, using the Healthy Eating Index 2010 (HEI-2010) and self-rated diet quality, (2) characteristics associated with reported awareness and use of nutrition information and (3) factors associated with HEI score and self-rated diet quality. DESIGN: Cross-sectional study. Based on Day 1 and/or Day 2 dietary recalls, the Per-Person method was used to estimate HEI-2010 component and total scores. T-tests and ANOVA were used to compare means. Logistic and linear regressions were used to test for associations with diet quality, controlling for potential confounders. SETTING: National Health and Nutrition Examination Survey, 2009-2014. PARTICIPANTS: Three thousand and fifty-six adults, aged 60 years and older, who completed at least one 24-h recall and answered questions on awareness and use of nutrition information. RESULTS: Mean HEI score for men was significantly lower than for women (56·4 ± 0·6 v. 60·2 ± 0·6, P < 0·0001). Compared with men, more women were aware of (44·8 % v. 33·7 %, P < 0·05) and used (13·7 % v. 5·9 %, P < 0·05) nutrition information. In multivariable analyses, awareness and use of nutrition information were significant predictors of both HEI and self-rated diet quality for both women and men. Groups with lower nutrition awareness included men, non-Whites, participants in nutrition assistance programmes and those with lower education and socio-economic status. CONCLUSIONS: Nutrition awareness and use of nutrition information are associated with diet quality in adults 60 years and older. Gaps in awareness of dietary guidelines in certain segments of the older adult population suggest that targeted education may improve diet quality for these groups.

OBJECTIVE: Decades of marginalization have led Palestinian refugees living in Lebanon to experience multigenerational poverty and food insecurity. The Healthy Kitchens, Healthy Children programme implemented and examined the impact of a two-pronged intervention that employed women through community kitchens to deliver a subsidized healthy daily school snack to elementary-school children in Palestinian refugee camps in Lebanon. We describe the rationale, study design, theorized impact pathways, and discuss lessons learned. DESIGN: The programme was quasi-experimental. We conducted formative and process evaluation of both components of the intervention to elucidate the pathways to programme impact. SETTING: Palestinian refugee camps in Lebanon. PARTICIPANTS: Thirty-three women participated in the kitchens and provided subsidized snacks to 714 children. RESULTS: Snacks were healthy, traditional Palestinian recipes designed by women and a nutritionist. Participation fluctuated but eventually increased after modifying the meals to ensure acceptability by children. The main challenges to sustainability related to the need for subsidization of the meals and the lack of school policies around the regulation of sales of school food, which together led to fluctuations in programme participation. CONCLUSIONS: The study provides lessons learned on the potential of this model to improve the human capital of two generations of protracted refugees. The availability of schools as a constant market for these social enterprises offers an opportunity for sustainable livelihood generation and food security gains. Challenges to sustainability remain and could be addressed through social (subsidies to support the programme) and structural (policies to restrict unhealthy food sales) measures.

The dose-response relationship between folate levels and cognitive impairment among individuals with vitamin B12 deficiency is an essential component of a risk-benefit analysis approach to regulatory and policy recommendations regarding folic acid fortification. Epidemiological studies provide data that are potentially useful for addressing this research question, but the lack of analysis and reporting of data in a manner suitable for dose-response purposes hinders the application of the traditional evidence synthesis process. This study aimed to estimate a quantitative dose-response relationship between folate exposure and the risk of cognitive impairment among older adults with vitamin B12 deficiency using "probabilistic meta-analysis," a novel approach for synthesizing data from observational studies. Second-order multistage regression was identified as the best-fit model for the association between the probability of cognitive impairment and serum folate levels based on data generated by randomly sampling probabilistic distributions with parameters estimated based on summarized information reported in relevant publications. The findings indicate a "J-shape" effect of serum folate levels on the occurrence of cognitive impairment. In particular, an excessive level of folate exposure is predicted to be associated with a higher risk of cognitive impairment, albeit with greater uncertainty than the association between low folate exposure and cognitive impairment. This study directly contributes to the development of a practical solution to synthesize observational evidence for dose-response assessment purposes, which will help strengthen future nutritional risk assessments for the purpose of informing decisions on nutrient fortification in food.

BACKGROUND: Recent studies have shown that children are able to accurately describe their own experiences of food insecurity; however, few studies have quantified this experience. OBJECTIVES: We aimed to develop and validate a child food security scale to be used in Arabic-speaking countries. METHODS: As part of the Healthy Kitchens Healthy Children study on food security and nutrition in schools, 14 questions were administered to 5-15-y-old children (n = 1433) attending 4 UN Relief and Works Agency for Palestine refugees schools. We used statistical methods based on Item Response Theory to assess the internal validity of a proposed food security scale using these items. Further validation of the scale was conducted by examining associations with sociodemographic, economic, household food security, and diet diversity variables through logistic regression models adjusted for age, sex, and school of the children. RESULTS: A total of 1287 children (89.8%) provided complete responses to the questionnaire. Four items were dropped from the scale because of high infit statistics (>1.3) and high residual correlation with other items. The resulting 10-item scale had acceptable reliability (Cronbach α coefficient = 0.89). Children who reported food insecurity were more likely to be from food-insecure households (OR: 2.3; P < 0.001). Food-insecure children came from households with lower expenditures per capita (OR: 0.80; P = 0.007) and higher household crowding (OR: 1.70; P = 0.001), and had less educated mothers (OR: 0.89; P = 0.009), lower household diet diversity (OR: 0.85; P < 0.001), and lower household consumption of meat (OR: 0.89; P < 0.001) and fruit (OR: 0.95; P = 0.001). Child food insecurity was also associated with higher school absenteeism (OR: 1.64; P = 0.01) and lower academic grades in languages and science (P < 0.05). CONCLUSIONS: Child food security was accurately measured through a 10-item scale. This tool is appropriate to assess child food insecurity experience directly with children, and can be used in school-based interventions, where obtaining data from parents may be cumbersome.

BACKGROUND: The aim of this study is to investigate the potential impact of a community-based intervention - the Healthy Kitchens, Healthy Children (HKHC) intervention - on participating women's household's economics and food security status, decision making, mental health and social support. METHODS: We established two healthy kitchens in existing community-based organizations in Palestinian camps in Lebanon. These were set up as small business enterprises, using participatory approaches to develop recipes and train women in food preparation, food safety and entrepreneurship. We used a mixed-methods approach to assess the impact of participating in the program on women's economic, food security, decision making, social and mental health outcomes. A questionnaire was administered to women at baseline and at an 8-month endpoint. The end line survey was complemented by a set of embedded open-ended questions. RESULTS: Thirty-two Palestinian refugee women were employed within the kitchens on a rotating basis. Participating women had a 13% increase in household expenditure. This was translated into a significant increase in food (p < 0.05) and clothing expenditures (p < 0.01), as well as a reduction in food insecurity score (p < 0.01). These findings were supported by qualitative data which found that the kitchens provided women with financial support in addition to a space to form social bonds, discuss personal issues and share experiences. CONCLUSIONS: This model created a social enterprise using the concept of community kitchens linked to schools and allowed women to significantly contribute to household expenditure and improve their food security.

Folate is a vitamin that plays a role as a cofactor and coenzyme in many essential reactions. These reactions are interrelated and any change in folate homeostasis could affect other reactions. With food fortified with folic acid, and use of multivitamin, unmetabolized folic acid (UMFA) has been detected in blood circulation, particularly among older adults. This has raised concern about the potential harmful effect of high folic acid intake and UMFA on health conditions such as cognitive dysfunction and cancer. To examine what is known about folate metabolism and the release of circulating UMFA, the Key Events Dose-Response Framework (KEDRF) was used to review each of the major key events, dose-response characteristics and homeostatic mechanisms of folate metabolism. The intestine, liver and kidneys each play essential roles in regulating body folate homeostasis. But the determining event in folate metabolism leading to the release of UMFA in circulation appears to be the saturation of dihydrofolate reductase in the liver. However, at each of the key events in folate metabolism, limited information is available on threshold, homeostatic regulation and intracellular effects of folic acid. More studies are needed to fill in the knowledge gaps for quantitatively characterizing the dose-effect relationship especially in light of the call for extending folate fortification to other foods.

The objective of this article was to describe 1) the validation of 2 similar but not identical food security modules used to collect data from 2 vulnerable populations, southern Lebanon residents (n = 815) and Palestinian refugees in Lebanon (n = 2501), and 2) the development and validation of an Arab Family Food Security Scale (AFFSS). The surveys used a cluster-randomized sampling design. The 2 food security subscales underwent face and construct validity. In addition, both of these tools and the AFFSS underwent psychometric assessment for internal validity by using statistical methods based on Item Response Theory. The food security questions tested by focus groups were understood and accepted in all regions of Lebanon. The food security subscales and the AFFSS had acceptable levels of internal consistency. The psychometric assessment confirmed that the 7 items of the AFFSS had good internal validity and reasonable reliability with item in-fits from 0.73 to 1.16. Food insecurity was identified among 42% of southern Lebanese and 62% of Palestinian refugee households. The determinants and consequences of food security measured in this study provide additional support for the validity of the modules. Using multivariate logistic regression, the higher the mean monthly income per household member and the higher the educational attainment of the head of household, the lower the risk of food insecurity [ORs (95% CIs): 0.99 (0.98, 0.99) and 0.66 (0.54, 0.80), respectively]. There was a strong significant association between food insecurity and lower food expenditure and lower intake of all food categories except for legumes, which was significantly associated in the opposite direction (P < 0.001). The odds of borrowing money and accepting gifts/donations were significantly higher among moderately and severely food-insecure households (P < 0.000). The AFFSS has been validated within Lebanon and can potentially be extended to other Arab-speaking populations.

Iraqi refugees in Lebanon are vulnerable to food insecurity because of their limited rights and fragile livelihoods. The objective of the present study was to assess household food insecurity among Iraqi refugees living in Lebanon, almost 10 years after the invasion of Iraq. A representative survey of 800 UN High Commissioner for Refugees-registered refugee households in Lebanon was conducted using multi-stage cluster random sampling. We measured food insecurity using a modified US Department of Agriculture household food security module. We collected data on household demographic, socio-economic, health, housing and dietary diversity status and analysed these factors by food security status. Hb level was measured in a subset of children below 5 years of age (n 85). Weighted data were used in univariate and multivariate analyses. Among the Iraqi refugee households surveyed (n 630), 20·1% (95% CI 17·3, 23·2) were found to be food secure, 35·5% (95% CI 32·0, 39·2) moderately food insecure and 44·4% (95% CI 40·8, 48·1) severely food insecure. Severe food insecurity was associated with the respondent's good self-reported health (OR 0·3, 95% CI 0·2, 0·5), length of stay as a refugee (OR 1·1, 95% CI 1·0, 1·2), very poor housing quality (OR 3·3, 95% CI 1·6, 6·5) and the number of children in the household (OR 1·2, 95% CI 1·0, 1·4), and resulted in poor dietary diversity (P< 0·0001). Anaemia was found in 41% (95% CI 30·6, 51·9) of children below 5 years of age, but was not associated with food insecurity. High food insecurity, low diet quality and high prevalence of anaemia in Iraqi refugees living in Lebanon call for urgent programmes to address the food and health situation of this population with restricted rights.

In the context of recent increases in international food prices, it is hypothesized that in rural communities retaining food production practices is important for protection against food insecurity at both the household and community levels, as well as for protection against the development of poor nutritional outcomes. To investigate this hypothesis, a cross-sectional study of household food security and nutritional status was carried out in a rural community of settled Bedouins in Lebanon comprising 84 households with 474 individuals; this tribe's recent history of settlement in 2 locations that differ by access to land and food production practices provides the context for this study. Food insecurity was found to be highly prevalent (49%) in this Bedouin community and was negatively associated with household food production (P < 0.05) and the consumption of fruits, chicken, meat, and fish (P < 0.05) and positively associated with consumption of cereal products (P < 0.01). This study shows that in small rural communities in a transitional country, sustaining food production may protect from food insecurity. Agricultural livelihood support programs that promote continued involvement in food production at the household and community level, in conjunction with other income-generating activities, may build resilience against food insecurity and improve dietary diversity.

OBJECTIVE: To explore (1) the services older adults use to address the barriers to food access they face and (2) how they found out about these services. DESIGN: Semistructured, basic descriptive qualitative in-person interviews. SETTING: Senior center and participants' homes. PARTICIPANTS: A convenience sample of 24 older adults recruited from suburban and urban settings. Primarily Black females, living alone, and able to leave home without help. PHENOMENON OF INTEREST: Financial and nonfinancial barriers to food access, awareness of services available. ANALYSIS: Codes were assigned to portions of the text in which participants described how they learned about a service. These codes were categorized into one of the 3 larger themes that emerged: (1) intentionally sought by the participant, (2) intentional outreach by the service, and (3) encounters in daily life and environment. RESULTS: Most connections to services were made through encounters in participants' daily life and environment; for example, word of mouth from family, friends or neighbors; connection through other services; referral from health care professionals; and seeing the service in their neighborhood. CONCLUSIONS AND IMPLICATIONS: Robust social networks, medical screening, and referral may promote awareness of food assistance services. Future research and outreach should target those who are most isolated.

This cross-sectional study assessed the nutrition and physical activity (PA) needs, practices, and programming preferences of adults ages 40+ years from seven states (n = 1,250). Respondents were mostly educated, White, food-secure, adults ages 60+ years. Many were married, suburban-residing, and interested in health programming. By self-report most respondents were "at nutritional risk" (59.3%), in "somewhat good health" (32.3%), and sedentary (49.2%). One-third reported PA intention in the next two months. Desired programs were less than four weeks and under 4 h weekly. Respondents preferred to attend self-directed online lessons (41.2%). Program format preference varied by age (P < 0.05). More respondents aged 40-49 years and 70+ years reported a preference for online group sessions compared to those aged 50 to 69 years. Respondents ages 60 to 69 years reported the highest preference for interactive apps. More older respondents (60 years and older) preferred asynchronous online lessons compared to the younger respondents (age 59 years and younger). There were significant program participation interest differences by age, race, and location (P< 0.05). These results revealed a need and preference for self-directed, online health programming for middle-aged and older adults.

Grandparents (GP) play influential roles in grandchildren's health, behavior, and life. However, this relationship has not been examined in the Arab region. This study assesses whether the presence of GP in the household is associated with grandchildren's health and wellbeing. Health status was determined by a child experiencing chronic health conditions or an acute illness, and wellbeing was determined based on school attendance and child labor. Data were collected through surveys conducted in 2010 and 2015 of representative samples of Palestinian refugees living in Lebanon. Multivariate logistic regression showed that, even after controlling for potential confounders, including the presence of parents in the household and household food insecurity (FI), the presence of live-in GP was associated with lower odds of children experiencing acute illnesses (OR 0.74 95% CI 0.62-0.92) and higher odds of attending school (OR 2.22 95% CI 1.28-5.33), but not child labor. The presence of GP in the household may be protective to grandchildren's health status and school attendance in this population.

The objective of this study was to measure direct and indirect relationships between food insecurity (FI), protein intake, social relationships, depressive symptoms, and their impact on hospitalization among home-delivered meal (HDM) recipients, compared to controls, using structural equation modeling. The analysis used data from the National Outcomes Evaluation Study (2015-2017) of the OAANSP. HDM recipients' mean usual protein intake was significantly higher than controls, but both groups had mean intakes below recommendations. Eating alone was inversely associated with lower protein intake and greater hospitalizations in controls. FI, prevalent in 25.1% of HDM recipient and 16% of controls, was associated with lower protein intake in both groups. Receiving instrumental social support was directly associated with lesser severity of FI in recipients. and more depressive symptoms only in controls. HDM recipients and controls may be at high risk for protein insufficiency, underscored by high prevalence of FI.

BACKGROUND: Sodium, potassium, and the balance between these 2 nutrients are associated with hypertension and cardiovascular disease, and prevalence of these conditions increases with age. However, limited information is available on these intakes among older adults. OBJECTIVE: Our aim was to explore the socioeconomic and health factors associated with usual sodium and potassium intakes and the sodium to potassium (Na:K) ratio of older adults. DESIGN: This was a cross-sectional, secondary analysis of the 2011-2012, 2013-2014, and 2015-2016 National Health and Nutrition Examination Survey. PARTICIPANTS/SETTING: This study included the data of 5,104 adults 50 years and older, with at least one reliable 24-hour dietary recall and an estimated glomerular filtration rate ≥60 mL/min/1.73 m2. MAIN OUTCOME MEASURES: Sodium and potassium intake, as absolute intake, density (per 1,000 kcal) and ratio of Na:K intake. STATISTICAL ANALYSES: We used t tests and χ2 tests to examine significant differences in intakes on a given day by characteristics. Linear and logistic regression models were used to assess associations of socioeconomic and health characteristics with usual sodium and potassium intakes, determined using the National Cancer Institute method. RESULTS: Only 26.2% of participants consumed <2,300 mg sodium (16.2% of men and 35.2% of women) and 36.0% of men and 38.1% of women consumed at least 3,400 mg and 2,600 mg of potassium, respectively. Fewer than one-third of participants consumed a Na:K ratio of <1.0. Women, those with lower blood pressure, and those with a lower body mass index were more likely to have a ratio <1.0. CONCLUSIONS: Participants consumed too much sodium and not enough potassium, based on current recommendations. A higher Na:K ratio was significantly associated with established risk factors for cardiovascular disease. The study findings suggest that more research on cardiovascular health should include both sodium and potassium, as well as balance between these nutrients.

The onset of dementia and Alzheimer's disease (AD) is projected to expand over the next several decades in the United States as the population ages. However, the cognitive health burden is not equally distributed among the population, as Hispanics and African Americans are at higher risk of AD when compared with Non-Hispanic Whites. There is some evidence to indicate that cognitive decline may be associated with lifestyle factors and that interventions in these domains may prevent or delay this decline. These lifestyle factors include social engagement, physical activity, both aerobic and strength training, dietary intake, sleep and stress. This review summarizes, in general, what is known about the relationship between risk factors and cognition and, in particular what is known about this relationship in minority populations. The results show that the relationship between these risk factors and cognitive decline is stronger for some of the factors such as physical activity and dietary intake and weaker for the other factors depending on what is measured and in what populations. It does appear, however, that the studies in minority populations is limited and warrants more targeted research and interventions.
RESUMEN
Improving care for the older population is a growing clinical need in the United States. Ageism and other attitudes of healthcare professionals can negatively impact care for older adults. This study investigated healthcare professionals' (N = 140) views towards aging and characterized a confluence of factors influencing ageism perspectives in healthcare workers using path analysis models. These models proposed relationships between aging anxiety, expectations regarding aging, age, ageism, and knowledge. Aging anxiety had a less critical role in the final model than hypothesized and influenced ageism in healthcare workers through its negative effect (ß = -0.27) on expectations regarding aging. In contrast, aging knowledge (ß = -0.23), age (ß = -0.27), and expectations regarding aging (ß = -0.48) directly and inversely influenced ageism. Increased knowledge about the aging process could lower ageism amongst healthcare professionals and improve care for older adults. The results put forth in this study help to characterize and understand healthcare workers' complex views towards the aging population they often encounter. Moreover, these results highlight the need and utility of leveraging practitioner education for combating ageism in the clinical setting.
