An adapted version of the U.S. Department of Agriculture Food Insecurity module is a valid tool for assessing household food insecurity in Campinas, Brazil

How to complement traditional instruments to measure the economic dimension of food security in older people? An application for regions of Argentina

Introduction: One of the dimensions of food security has to do with economic access to food. Aim: Propose a methodology that allows evaluating economic access to food in Argentina for the elderly population. Methods: Dietary guides for the Argentine population are used. Meanwhile, the food consumption patterns observed in the elderly population in Argentina are considered from a household expenditure survey, from which implicit food prices can also be obtained. Results: Six dietary plans corresponding to different regions of the country are designed and evaluated and it is found that they would be affordable only in two of the six regions analyzed. Conclusion: in the Metropolitan, Pampas, Cuyo, and Northeast regions the cost of the ideal basket is higher than food spending, fundamentally in the Northeast region where food spending should increase by 25%.

Food and nutrition security definitions, constructs, frameworks, measurements, and applications: global lessons

Food security (FS) is a powerful social determinant of health (SDOH) and is crucial for human and planetary health. The objectives of this article are to (i) provide clarity on the definitions of FS and nutrition security; (ii) provide a framework that clearly explains the links between the two constructs; (iii) summarize measurement approaches, and (iv) illustrate applications to monitoring and surveillance, policy and program design and evaluation, and research, mainly based on the ongoing rich experience with food insecurity (FI) scales. A clear and concise definition of FI and corresponding frameworks are available. There are different methods for directly or indirectly assessing FI. The best method(s) of choice need to be selected based on the questions asked, resources, and time frames available. Experience-based FI measures disseminated from the United States to the rest of the world in the early 2000s became a game changer for advancing FI research, policy, program evaluation, and governance. The success with experience FI scales is informing the dissemination, adaptation, and validation of water insecurity scales globally. The many lessons learned across countries on how to advance policy and program design and evaluation through improved FS conceptualization and measurement should be systematically shared through networks of researchers and practitioners.

Poverty-Food Insecurity Nexus in the Post-Construction Context of a Large Hydropower Dam in the Brazilian Amazon

Within the 2030 Sustainable Development Agenda, large hydropower dams are positioned as a sustainable energy source, notwithstanding their adverse impacts on societies and ecosystems. This study contributed to ongoing discussions about the persistence of critical social issues, even after the investments of large amounts of resources in areas impacted by the construction of large hydropower dams. Our study focused on food insecurity and evaluated this issue in the city of Altamira in the Brazilian Amazon, which has been profoundly socially and economically impacted by the construction, between 2011 and 2015, of Brazil's second-largest dam, namely, Belo Monte. A survey in Altamira city featured a 500-household random sample. Structural equation modeling showed conditioning factors of 60% of the population experiencing varying food insecurity degrees. Poverty, female-led households, lower education, youth, and unemployment were strongly linked to higher food insecurity. Crowded, officially impacted, and resettled households also faced heightened food insecurity. Our findings underscore the food insecurity conditions in the region impacted by the Belo Monte dam, emphasizing the need to take into account this crucial issue while planning and implementing hydropower dams.

Adherence to the EAT-Lancet diet and its relation with food insecurity and income in a Brazilian population-based sample

This study aimed to investigate the relation of adherence to the planetary diet with food and nutrition security status and per capita household income in a study with a representative sample of the Brazilian population. Among the data from the 2017-2018 Brazilian Household Budgets Survey (POF), the inequality indicators selected for the analysis were data on per capita household income and food and nutrition security. We also considered data on the individual food consumption of 46,164 Brazilians aged ≥ 10 years, obtained through 24-hour dietary recalls, in the National Food Survey, conducted with the POF 2017-2018. The Planetary Health Diet Index (PHDI) was used to measure adherence to the planetary diet. Sociodemographic data were expressed as frequency (%), with analysis of the mean and 95% confidence interval (95%CI) of the PHDI score. The relation of food and nutrition security and income with the PHDI score was tested in multiple linear regression models. The calculations were performed in the Stata software, adopting a 5% significance. Lower PHDI means were observed among food insecure individuals, male, < 20 years old, mixed-race and indigenous, with income < 0.5 minimum wage, residing in rural areas and in the North and Northeast regions. In the multiple linear regression, food insecurity was inversely related to PHDI score (ꞵ = -0.56; 95%CI: -1.06; -0.06), with the lowest scores associated with severe food insecurity (β = -1.31; 95%CI: -2.19; -0.55). Income categories were not independently associated to PHDI score (p-trend = 0.900). Therefore, food insecurity has been shown to negatively affect Brazilians' adherence to the planetary diet.

Factors Associated with Continued Breastfeeding Practice in Children Under 2 Years of Age Assisted by the Brazilian Conditional Cash Transfer Program, Bolsa Família

Breastfeeding is the first guarantee of the human right to adequate food and the benefits of continued breastfeeding up to 2 years of age are well established. This cross-sectional study sought to explore the association between socioeconomic, demographic, and nutritional factors and the practice of continued breastfeeding in children aged 6 to 24 months assisted by the Brazilian conditional cash transfer program, Bolsa Família. Our findings emphasize the role of unfavorable socioeconomic conditions in diminishing the practice of continued breastfeeding. They also suggest the importance of policy-level actions to promote and support breastfeeding and to combat early ultra-processed foods consumption.

Gender, skin color, and household composition explain inequities in household food insecurity in Brazil

It is well known that female-headed households (FHHs) are more likely to experience food insecurity (FI) than male-headed households (MHHs), however there is a dearth of evidence on how gender intersects with other social determinants of FI. Thus, this paper investigated changes in the prevalence of household FI in Brazil from 2004 to 2018 by the intersection of gender, race/skin color and marital status of the household reference person. Data from three cross-sectional nationally representative surveys that assessed the status of FI using the Brazilian Household Food Insecurity Measurement Scale were analyzed (N2004 = 107,731; N2013 = 115,108, N2018 = 57,204). Multinomial logistic regression models were used to examine the relationship between profiles of gender, race/skin color, marital status of the head of the household with household FI stratified by the presence of children <5 years of age. Over time, FHHs had a higher prevalence of mild and moderate/severe FI than did households headed by men. Food security prevalence increased from 2004 to 2013 and decreased between 2013 and 2018 for households headed by men and women. In 2018, households headed by black/brown single mothers with children < 5 years of age were at the highest FI risk. The probability of reporting moderate/severe FI in these households were 4.17 times higher (95% CI [2.96-5.90]) than for households headed by married white men. The presence of children in the household was associated with a higher probability of moderate/severe FI, especially for households headed by black/brown individuals regardless of the reference person's gender. The results suggest that gender inequities combined with darker skin color and the presence of children at home potentiate the risk of moderate/severe FI. Policy makers need to consider the principles of intersectionality when investing in codesigning, implementing, evaluating, and scaling up evidence-based programs to reduce FI.

Addressing food insecurity: what is the role of healthcare?

Food insecurity - when individuals or households have difficulty accessing sufficient, safe, culturally appropriate and nutritious food due to lack of money or other resources - is a global public health concern. Levels of food insecurity have increased across the UK in recent years, due in part to a decade of austerity, widespread loss of income during the COVID-19 pandemic and the more recent cost-of-living crisis, leading to rising use of food banks. The stress of living with uncertain access to food and going periods without food is damaging to physical and mental health. Food insecurity is linked to both obesity and malnutrition, as often the most readily available foods are processed, high in fats, sugars and salt, but low in essential nutrients for health. While recognising that many of the drivers of food insecurity, and health inequalities more broadly (i.e. the social determinants of health) lie outside the health service, it is increasingly acknowledged that the National Health Service - and primary care in particular - has a key role to play in mitigating health inequalities. This review considers the potential role of healthcare in mitigating food insecurity, with a focus on primary care settings. Recent initiatives in Scotland, such as community links workers and general practitioner practice-attached financial advice workers, have shown promise as part of a more community-oriented approach to primary care, which can mitigate the effects of food insecurity. However, a more 'upstream' response is required, including 'cash first' interventions as part of broader national strategies to end the need for food banks.

Diet quality and associated factors in Brazilian undergraduates during the COVID-19 pandemic

Background

Diet quality is associated with psychobiological, psychological, biological, and physiological factors of individuals, and in the context of prolonged stress, such as the COVID-19 pandemic, it can lead to a worsening of the quality of food for undergraduates. This study aimed to analyze diet quality and associated factors in Brazilian undergraduates.

Methods

Data were collected from 4,799 undergraduate students from all Brazilian regions, from August 2020 to February 2021. The online questionnaire contained socioeconomic variables, the ESQUADA scale to assess diet quality, self-referred changes in weight, the Brazilian food insecurity scale (EBIA), sleep assessment and the perceived stress scale. Unconditional multiple logistic regression analysis was performed to study variables associated with poor and very poor diet quality.

Results

Most of participants presented a good diet quality (51.7%), while 9.8% had a poor or very poor diet quality and only 1.1% had an excellent diet quality. 58.2% of undergraduates reported to have an increase in weight during the pandemic and 74.3% of the students presented elevated stress during the pandemic. Logistic regressions showed students who gained weight during the pandemic presented the highest AOR = 1.56 (95% CI = 1.12-2.20) for poor or very poor diet quality. The elevated perceived stress was also associated with a higher AOR = 2.85 (95% CI = 1.71-4.74) for poor or very poor diet quality.

Conclusion

Most of the studied undergraduates presented a good diet quality. Nevertheless, poor/very poor diet quality was associated with higher perceived stress and weight gain. Our study indicated that policies should beaimed at the socioeconomically most vulnerable undergraduates, those in a situation of food and nutritional insecurity, high perceived stress, and who gained weight during the pandemic.

Relative validity and reproducibility of WHO indicators for assessment of feeding practices in children under two years of age

The study aimed to evaluate relative validity and reproducibility of seven WHO indicators of dietary practices in children aged 6-23.9 months. Data from probabilistic sample of children who used primary healthcare services in Rio de Janeiro, Brazil were collected using a 24h dietary recall (24HR) and a closed questionnaire (Q1) on feeding in the day before the study. The last one was reapplied (Q2) around 16 days later. Validity was assessed by comparing the prevalence rates estimated by 24HR and Q1 and calculating the positive (PPV) and negative (NPV) predictive values, sensitivity (Se), specificity (Sp), and accuracy index (AI) for the resulting indicators. For reproducibility, estimated prevalence rates based on Q1 and Q2 were compared and the kappa index and prevalence-adjusted bias-adjusted kappa were estimated. Of the seven estimated indicators, the prevalence of two was overestimated (Continued breastfeeding: 50.0% vs 40.0%; Sweet beverage consumption: 65.1% vs 52.7%) and the prevalence of one was underestimated (Zero vegetable or fruit consumption: 6.5% vs 18.1%). For most indicators, Se and PPV were higher than Sp and NPV. The prevalence rates determined with Q1 and Q2 were similar for 6 indicators. More than half showed good, very good or excellent agreement.

Patterns of energy balance-related behaviors and food insecurity in pregnant women

The behaviors related to caloric balance during pregnancy can lead to short- and long-term repercussion over the life course. This study aimed to identify patterns of energy balance-related behavior (EBRB) and its association with food insecurity (FI) in pregnant women. Cross-sectional, with pregnant women undergoing prenatal care in public health units in Colombo, Brazil, in 2018/2019. EBRB patterns were identified by factor analysis, and the scores were compared according to FI levels (mild and moderate/severe (M/S) through quantile regression. Four EBRB patterns were identified among 535 pregnant women: Factor 1- household/caregiving activities, exercise/sport, and physical inactivity; Factor 2 - fruits and vegetables; Factor 3 - paid work and commuting; Factor 4 - soda and sweetened beverage, sweets, and goodies. After adjusted analyses, women with mild FI presented higher scores for Factor 1 and lower scores for Factor 3. Higher scores for Factor 4 (p25) were observed among women with mild FI in simultaneous quantile regression. M/S FI was associated with lower scores for Factor 3 (p75). Mixed patterns with factors negatively and positively associated with energy balance were identified among pregnant women with FI.

Household food insecurity before and during COVID-19 pandemic and its association with perceived stress: population-based studies

The growing prevalence of food insecurity observed in the last years, has been favored by the COVID-19 pandemic, leading to mental health issues, such as stress. We aim to analyze the prevalence of household food insecurity before and during the COVID-19 pandemic and its association with perceived stress. We analyzed data from two population-based studies conducted in 2019 and 2020-2021 in the municipality of Criciúma, State of Santa Catarina, Southern Brazil. Food insecurity and perceived stress were assessed with the Brazilian Food Insecurity Scale and the Perceived Stress Scale. The covariables were sex, age, skin color, schooling level, income, job status, marital status, household crowding, overweight, and diet quality. Crude and adjusted associations between food insecurity and perceived stress were assessed using Poisson regression. A total of 1,683 adult individuals were assessed. Prevalence of food insecurity was 25.8% in 2019, decreasing to 21.6% in 2020. Prevalence of perceived stress was about 38% for both years. Before the pandemic, food insecurity increased the prevalence of perceived stress by 29% (PR = 1.29; 95%CI: 1.02; 1.63), but no association was found during COVID-19. We found a worrying prevalence of food insecurity before and after de pandemic, nonetheless food insecurity and perceived stress were associated only in 2019. An assessment of these aspects after COVID-19 is needed to ensure basic life rights for all.

A Descriptive Systematic Review of Food Insecurity and Intimate Partner Violence in Southern Africa

Food insecurity and intimate partner violence are important determinants of health and wellbeing in southern Africa. However, very little research has attempted to investigate the association between them even though food insecurity is anticipated to increase in the region, mostly owing to climate change. The objective of this paper was to descriptively review peer reviewed studies that investigated the relationship between food insecurity and intimate partner violence in southern Africa. Literature searches were carried out in Scopus, Web of Science and PubMed databases without any time restriction. A total of five studies that investigated the association between food insecurity and intimate partner violence were identified in South Africa and Swaziland. Of these four studies used a cross-sectional design, and one employed a longitudinal design. Samples varied from 406 to 2479 individuals. No empirical studies were found for the remaining southern African countries of Angola, Botswana, Malawi, Namibia, Zambia, Zimbabwe, Lesotho, and Mozambique. Moreover, the reported findings indicated that there was an association between food insecurity and interpersonal violence (i.e., physical, psychological, and emotional) in the sub-region regardless the fact that the five studies used diverse measurements of both food insecurity and intimate partner violence.

SNAP participation moderates the association between household food insecurity and HbA1c among Cambodian Americans with depression

OBJECTIVES

We tested whether participation in the Supplemental Nutrition Assistance Program (SNAP) moderated the relation between household food insecurity and HbA1c among Cambodian Americans with depression enrolled in a diabetes prevention trial.

METHODS

Community health workers assessed household food insecurity and SNAP participation. HbA1c was ascertained using direct enzymatic assay.

RESULTS

Among the n = 189 respondents, 19% were food insecure, 41% received SNAP benefits, and mean HbA1c = 5.5%. There was a significant interaction between SNAP and food insecurity. HbA1c was highest among participants without SNAP who were food insecure. Simple effects analysis revealed a significant difference within the no SNAP group [Mean (SD): Secure = 5.38 (0.38), Insecure = 5.78 (0.36)] and no difference within the SNAP group [Secure = 5.61(0.44), Insecure = 5.61(0.55)]. Differences remained significant after controlling for demographic, socioeconomic, and clinical indicators.

CONCLUSIONS

SNAP may protect against the deleterious association between household food insecurity and HbA1c.

[Validity of an instrument for screening households at risk of food insecurity in different strata of the Brazilian population]

The absence of risk screening tools for food insecurity compromises the ability to assess, monitor, and provide immediate assistance to those in hunger, especially during emergencies such as the COVID-19 crisis. Hence, this study sought to test the validity of an instrument for Screening Households at Risk of Food Insecurity (TRIA) in different strata of the Brazilian population TRIA uses questions 2 and 4 of the Brazilian Food Insecurity Scale (EBIA), originally validated using data from the Brazilian National Survey of Demography and Health of Children and Women (PNDS 2006). In this study, using data from the Brazilian National Household Sample Survey (PNAD 2013), its reproducibility was tested by repeating the original combinatorial procedures, examining whether the parameters of sensitivity, specificity, accuracy, and positive predictive values (PPV) and negative values (NPV) would result in the same arrangement of questions. Moreover, convergent validity was analyzed by comparing the strength of association between food insecurity and dietary variables using two binomial regression models (TRIA x EBIA). Results indicated that the combination of questions 2 and 4 performed best among the population strata studied, and presented optimal convergent validity. PPV and NPV adjusted for food insecurity prevalence in states ranged from 42.8% (Santa Catarina) to 87.6% (Amazonas) and 95.8% (Amazonas) to 99.5% (Santa Catarina), respectively. In conclusion, besides being reproducible, TRIA presented excellent validity parameters, especially among vulnerable groups. It can thus be used in care practice and as an instrument of food and nutritional surveillance in Brazil.

Relationship between sleep duration and quality and mental health before and during COVID-19 pandemic: Results of population-based studies in Brazil

OBJECTIVE

This study aimed to evaluate the association between sleep duration and quality and mental health before and amid the COVID-19 pandemic.

METHODS

Data from two population-based cross-sectional studies conducted in 2019 and 2020 with adults in Criciúma, Southern Brazil. The Patient Health Questionnaire-9 (PHQ-9) was used to screen major depressive episodes, while the perceived stress scale was used to assess perceived stress. Sleep was evaluated through self-reported duration and quality. Crude and adjusted Poisson regression models were used to assess the association between sleep and mental health disorders.

RESULTS

A total of 820 (in 2019) and 863 subjects (in 2020) were assessed. Sleep quality presented significant associations with depression and stress in both years, and the magnitude of the association with depression increased amid COVID-19 pandemic. In individuals with poor/very poor sleep quality, the risk of depression in 2019 was 2.14 (95%IC 1.48;3.09) higher when compared to those with good/very good sleep quality. This risk increased to 2.26 (95%IC 1.49;3.40) in 2020. The risk of stress was 1.90 (95%IC 1.42;2.55) in 2019 and 1.66 (95%IC1.34;2.07) in 2020. The sleep duration was not associated with mental health disorders in the adjusted analyses.

CONCLUSION

The results provide important evidence that sleep quality can influence mental health of adults. The COVID-19 pandemic seems to have had a considerable impact on this association.

Access to governmental programs/benefits and food insecurity in urban and rural areas of Northeast Brazil

This paper analyzes food insecurity (FI) in urban and rural areas of the Northeast region of Brazil associated with certain social determinants and access to governmental benefits/programs. Data about FI from the National Household Budget Survey (2017-2018) were analyzed, including socio-economic variables and access to government benefits/programs of supplemental income (Bolsa Família, Ongoing transfer benefits, Food voucher and Food basket). Multinomial logistic regression models were performed to assess the relationship between FI and access to government programs/benefits. Half of the families in the Northeast were classified as being subject to FI, the prevalence and severity being higher in rural households. The composition of the family, with at least one retired individual, significantly reduced the probability of being FI at all levels of severity. Access to the Food basket (in cash) benefit and Bolsa Família was associated with being a factor of protection against severe FI in rural areas, while in urban areas the food voucher benefit was the main factor of protection. Income transfer programs and access to social benefits contribute to combatting FI, highlighting the importance of maintaining and scaling-up these initiatives for vulnerable populations.

Mental distress and food insecurity in pregnancy

Abstract Food insecurity is a source of daily stress, especially in women. The aim was to investigate the association between mental distress and food insecurity in pregnant women. Cross-sectional study with pregnant women from the public health service, regardless risk stratification, or gestational trimester in Colombo-PR, Brazil. Poisson regression models were progressively adjusted for exposure variables. Results: Among the participating pregnant women (N=513) the prevalence of mental distress was 50.1%; associated with mild food insecurity (PR 1.34, 95%CI 1.12; 1.61) and moderate/severe food insecurity (PR 1.70, 95%CI 1.33; 2.19). The variable that most changed the association between the outcome and mild food insecurity was income (-4.48%) and, for moderate/severe food insecurity, education (-7.60%). For mild and moderate/severe food insecurity, the greatest reduction occurred with socioeconomic variables 4.5% (PR 1.27, 95%CI 1.05; 1.53) and 8.0% (PR 1.50, 95% CI 1.17; 1.93), respectively. The association between food insecurity and mental distress was consistent, and increased with the degree of food insecurity, with a greater reduction for socioeconomic variables.

National Trends and Disparities in Severe Food Insecurity in Brazil between 2004 and 2018

Background

The Brazilian Household Food Insecurity Measurement Scale (EBIA) is the main tool for assessing household food insecurity (FI) in Brazil and facilitates the monitoring and improvement of national public policies to promote food security. Since 2004, the Brazilian government has conducted National Household Sample Surveys, and in 2018, the government carried out the last national evaluation of FI.

Objectives

To describe trends in severe FI in Brazil from 2004 to 2018.

Methods

Data from 3 cross-sectional Brazilian National Household Sample Surveys (sample sizes: 2004 = 112,530; 2009 = 120,910; 2013 = 116,196) and from the last Household Budget Survey (sample size = 57,920) that assessed the status of FI using the EBIA were analyzed. Changes in severe FI during 2 periods (2004-2013; 2013-2018) were estimated while considering sociodemographic factors.

Results

The period between 2004 and 2013 was marked by a significant decrease in severe FI (-53.6%), but this trend reversed in 2013-2018 (+43.8%). The greatest decrease in severe FI occurred in the Northeast (-57.6%) among households where the reference person was a man (-57.6%) and self-identified as white (-58.1%) (2004-2013). In 2013-2018, households with children aged ≤4 y (+6.3%) and members aged ≥65 y (+12.5%) experienced the lowest increases in severe FI.

Conclusions

After a significant reduction from 2004 to 2013, severe FI increased sharply from 2013 to 2018, likely due to disruptions in public policies aimed at reducing hunger and unemployment rates.

DNA methylation mediates a randomized controlled trial home-visiting intervention during pregnancy and the Bayley infant's cognitive scores at 12 months of age

The crosstalk between maternal stress exposure and fetal development may be mediated by epigenetic mechanisms, including DNA methylation (DNAm). To address this matter, we collect 32 cord blood samples from low-income Brazilian pregnant adolescents participants of a pilot randomized clinical intervention study (ClinicalTrials.gov, Identifier: NCT02807818). We hypothesized that the association between the intervention and infant neurodevelopmental outcomes at 12 months of age would be mediated by DNAm. First, we searched genome methylation differences between cases and controls using different approaches, as well as differences in age acceleration (AA), represented by the difference of methylation age and birth age. According to an adjusted p-value ≤ 0.05 we identified 3090 differentially methylated positions- CpG sites (DMPs), 21 differentially methylated regions (DMRs) and one comethylated module weakly preserved between groups. The intervention group presented a smaller AA compared to the control group (p = 0.025). A logistic regression controlled by sex and with gestational age indicated a coefficient of -0.35 towards intervention group (p = 0.016) considering AA. A higher cognitive domain score from Bayley III scale was observed in the intervention group at 12 months of age. Then, we performed a potential causal mediation analysis selecting only DMPs highly associated with the cognitive domain (adj. R2 > 0.4), DMRs and CpGs of hub genes from the weakly preserved comethylated module and epigenetic clock as raw values. DMPs in STXBP6, and PF4 DMR, mediated the association between the maternal intervention and the cognitive domain at 12 months of age. In conclusion, DNAm in different sites and regions mediated the association between intervention and cognitive outcome.

Access to governmental programs/benefits and food insecurity in urban and rural areas of Northeast Brazil

Abstract This paper analyzes food insecurity (FI) in urban and rural areas of the Northeast region of Brazil associated with certain social determinants and access to governmental benefits/programs. Data about FI from the National Household Budget Survey (2017-2018) were analyzed, including socio-economic variables and access to government benefits/programs of supplemental income (Bolsa Família, Ongoing transfer benefits, Food voucher and Food basket). Multinomial logistic regression models were performed to assess the relationship between FI and access to government programs/benefits. Half of the families in the Northeast were classified as being subject to FI, the prevalence and severity being higher in rural households. The composition of the family, with at least one retired individual, significantly reduced the probability of being FI at all levels of severity. Access to the Food basket (in cash) benefit and Bolsa Família was associated with being a factor of protection against severe FI in rural areas, while in urban areas the food voucher benefit was the main factor of protection. Income transfer programs and access to social benefits contribute to combatting FI, highlighting the importance of maintaining and scaling-up these initiatives for vulnerable populations.

A cor e o sexo da fome: análise da insegurança alimentar sob o olhar da interseccionalidade

Este trabalho objetiva analisar a (in)segurança alimentar domiciliar sob o olhar da interseccionalidade. Para isso, foram analisados 14.713 domicílios, utilizando-se um questionário estruturado e a Escala Brasileira de Insegurança Alimentar, além dos dados do estudo transversal Qualidade do Ambiente Urbano de Salvador - QUALISalvador, realizado entre 2018 e 2020 em Salvador, Bahia, Brasil. A variável desfecho foi a situação de segurança alimentar (insegurança alimentar leve, moderada ou grave) e a variável exposição de interesse foi o cruzamento de raça/cor e sexo autodeclarado (homem branco, mulher branca, homem negro, mulher negra). Modelos de regressão logística multinominal foram usados para estimar a associação entre a exposição de interesse e o desfecho, ajustada a partir de questões socioeconômicas estratificadas segundo escolaridade e renda familiar per capita. Diante disso, concluiu-se que domicílios chefiados por mulheres negras apresentaram maior chance de insegurança alimentar leve (OR = 1,39; IC95%: 1,15-1,68; p = 0,001) e moderada ou grave (OR = 1,94; IC95%: 1,49-2,52; p < 0,001) em relação aos domicílios chefiados por homens brancos, além de maior chance de insegurança alimentar moderada ou grave em todos os níveis de escolaridade e nas faixas de até 1/2 salário mínimo e > 1 salário mínimo. Quando os responsáveis foram homens negros, a maior chance se apresentou na faixa > 1 salário mínimo. A insegurança alimentar nos domicílios chefiados por mulheres negras, mesmo em condições socioeconomicamente favoráveis, revela-se como uma das consequências da interação estrutural do racismo e do sexismo.

Factors associated with early childhood development in municipalities of Ceará, Brazil: a hierarchical model of contexts, environments, and nurturing care domains in a cross-sectional study

Background

This study aims to identify the contexts, environments, and nurturing care predictors that determine whether a child is developmentally on track in Ceará, Brazil.

Methods

We analysed data from a cross-sectional study conducted with caregivers of 6,447 children aged 0-59 months during a vaccination campaign in Ceará in October 2019. The validated Child Development Assessment Questionnaire was used to assess early childhood development (ECD) and children with a z-score ≥ -1 SD were considered developmentally on track. We conducted logistic regression models to understand the effects of contexts, environments, and nurturing care domains on ECD.

Findings

Children in the early years (< 36 months) were more likely to meet the ECD milestones if they were not born with low birth weight (AOR: 0·64; 95% CI: 0·42-0·97), were exposed to manufactured toys in their house (2·68; 1·97-3·66), their heads of household were employed (1·61; 1·16-2·23), and their caregivers had read the Child Health Handbook (1·42; 1·13-1·77) and engaged them in stimulating activities (1·71; 1·26-2·32). Children aged 36-59 months were more likely to meet the ECD milestones if they were breastfed (never: ref. / < 3 months: 3·72; 1·91-7·26 / 3-5 months: 3·21; 1·74-5·93 / 6-11 months: 3·73; 1·95-7·16 / ≥ 12 months: 3·89; 2·25-6·72), had books at home (0: ref / 1-3: 1·71; 1·22-2·40 / 4-6: 2·24; 1·27-3·94 / 7+: 2·71; 1·05-7·00), and their caregivers received information about ECD (1·49; 1·11-2·01) and engaged them in stimulating activities (1·80; 1·27-2·56). Children aged 36-59 months were less likely to meet developmental milestones if they watched TV or used tablets/smartphones for more than two hours per day (0·61; 0·44-0·84), played with household objects (0·62; 0·41-0·92), participated in governmental early childhood programmes aimed at vulnerable families (0·62; 0·45-0·86), had families that participated in income transfer programmes (0·68; 0·47-0·99) (families living in poverty or extreme poverty), and their caregivers considered slapping (0·67; 0·48-0·94) a necessary disciplinary method.

Interpretation

Having favourable socioeconomic conditions, breastfeeding, the absence of harsh discipline, caregivers who provide responsive care, and the provision of opportunities for early learning are the key factors that increase the likelihood of a child achieving their full developmental potential in Ceará, Brazil.

Household Food Security and Associated Factors among Portuguese Children

This study investigated the household food insecurity (HFI) among Portuguese children following the last world financial crisis. A cross-sectional study was conducted on 4737 Portuguese children (3-11 yrs). Socio-demographics, food insecurity, and household geographic location were assessed via questionnaire. Nutritional status was measured. Following the economic crisis, 14.2% of school children and 12.0% of preschool children experienced HFI. Preschool children having parents with low and medium parental education (paternal: OR = 4.4; 95% CI 2.7-7.1 and OR = 2.4; 95% CI 1.5-3.6; maternal: OR = 2.2; 95% CI 1.4-3.5 and OR = 1.6; 95% CI 1.1-2.3), living in the south (OR = 1.4; 95% CI 1.0-2.0) and being overweight/obese (OR = 1.1; 95% CI 0.7-1.3) were more likely to experience HFI than food secure household peers. Higher OR of belonging to a food insecure household were observed in school-aged children with low and medium parental education (paternal: OR = 2.9; 95% CI 1.9-4.6 and OR = 1.7; 95% CI 1.1-2.5; maternal: OR = 2.5; 95% CI 1.6-3.9 and OR = 2.3; 95% CI 1.6-3.3), living in Coimbra (OR = 1.7; 95% CI 1.1-2.6) and being overweight/obese (OR = 1.3; 95% CI 0.8-1.5) compared to food secure household peers. Data are instructive and support the need to increase awareness of HFI, reduce its incidence in overweight/obese children from low socio-economic status families and specific geographic areas, and increase food availability based on local ecology.

Changes in prevalence of overweight in adolescents living in areas highly vulnerable to food insecurity

This study ascertained changes, over 5 years, in the prevalence of overweight in adolescents and associations with socio-demographic variables and food insecurity. Two cross-sectional population-based studies were conducted with 511 (2005) and 314 (2010) adolescents resident in Campos Elíseos (Duque de Caxias-RJ). Overweight was evaluated by sex and age specific cut-off points of BMI (weight/height²). The prevalence of food insecurity was investigated using the Brazilian Food Insecurity Scale. Logistic regression was used to determine the association between changes in overweight over time and sex, age, skin colour, and food insecurity. Overweight was found to increase significantly, between 2005 and 2010, in boys who were younger (from 20.1% to 49.5%), black or brown (22.2% to 37.3%), those with per capita income of up to half a minimum wage (13.6% to 32.5%) and those experiencing moderate or severe food insecurity (9.2% to 36.3%). It was concluded that overweight increased significantly in adolescents living in an area of food insecurity, and that younger, black or brown, lower-income adolescents, and those living with moderate and severe food insecurity, were more exposed to that increase.

Dietary patterns of children aged 6-24 months assisted by the Bolsa Família Program

OBJECTIVE

This study aimed to verify the association between socio-economic and demographic characteristics and dietary patterns (DP) of children assisted by the Conditional Cash Transfer Program, Bolsa Família Program (BFP).

DESIGN

This is a cross-sectional study. DP were defined using a principal component analysis. The association of the predictive variables and DP was modelled using multilevel linear regression analysis.

SETTING

This study was conducted in six municipalities from the State of Alagoas, Brazil.

PARTICIPANTS

The participants were children aged 6-24 months who were assisted by the BFP.

RESULTS

A total of 1604 children were evaluated. Four DP were identified (DP1, DP2, DP3 and DP4). DP1 is composed of traditional Brazilian food. DP2 is formed mostly from ultra-processed foods (UPF). DP3 consists of milk (non-breast) with added sugar, while DP4 consists of fresh and minimally processed foods. Caregivers with higher age and education (β = -0·008; (95 % CI -0·017, -0·000); β = -0·037; (95 % CI -0·056, -0·018), respectively) were negatively associated with DP2. We observed a negative association between households with food insecurity (β = -0·204; (95 % CI -0·331, -0·078)) and DP4 and a positive association between caregivers with higher age and education (β = 0·011; (95 % CI (0·003; 0·019); β = 0·043; (95 % CI 0·025, 0·061), respectively) and DP4.

CONCLUSION

This study identified the association between socio-economic inequities and DP early in life, with an early introduction of UPF, in children assisted by BFP in the State of Alagoas.

Factors associated with childhood anaemia in Afro-descendant communities in Alagoas, Brazil

OBJECTIVE

To investigate factors associated with anaemia in preschool children.

DESIGN

A home survey was conducted in 2018. Anaemia in children (capillary blood Hb level < 110 g/l) was the outcome, and socio-economic, demographic and health factors of the mother and child were the independent variables. The measure of association was the prevalence ratio, and its 95 % CI was calculated using Poisson's regression with robust variance and hierarchical selection of independent variables.

SETTING

Afro-descendants communities living in the state of Alagoas, northeast Brazil.

PARTICIPANTS

Children aged 6-59 months and their mothers (n 428 pairs).

RESULTS

The prevalence of child anaemia was 38·1 % (95 % CI 33·5, 42·7). The associated factors with child anaemia were male sex, age < 24 months, larger number of residents at home (> 4), relatively taller mothers (highest tertile) and higher z-score of BMI for age, after further adjustment for wealth index, vitamin A supplementation in the past 6 months and clinical visit in the last 30 d.

CONCLUSIONS

The high prevalence of anaemia observed reveals a relevant public health problem amongst children under five from the quilombola communities of Alagoas. Considering the damage caused to health and multiplicity of risk factors associated with anaemia, the adoption of intersectoral strategies that act on modifiable risk factors and increase vigilance concerning those that are not modifiable becomes urgent.

Food insecurity and sociodemographic factors among children in São José dos Pinhais, Paraná, Brazil, 2017: a cross-sectional study

OBJECTIVE

To analyze association between food insecurity (FI) and sociodemographic factors among children.

METHODS

The study was carried out from May to November 2017 with mothers of children (18 - 35 months old) enrolled at public education facilities in São José dos Pinhais, Paraná, Brazil. FI was determined by the Brazilian Household Food Insecurity Measurement Scale. Multinomial logistic regression was used with a hierarchical model.

RESULTS

395 mothers/children participated. Overall FI prevalence was 34.7% (95%CI 28.5;41.5), with prevalence of 25.7% (95%CI 19.2;32.3) for mild FI (MFI) and 9.0% (95%CI 8.5;9.4) for moderate/severe FI (MSFI). Families in the lowest income tercile had higher likelihood of MFI (OR=3.06 - 95%CI 1.26;7.41) or MSFI (OR=6.35 - 95%CI 1.89;21.4) when compared to the highest tercile. Higher MFI prevalence was identified in male children (OR=2.34 - 95%CI 1.49;3.68).

CONCLUSION

FI was associated with lower income and MFI with male children. Public policies to increase income must be included in FI reduction strategies.

Psychometric properties of a modified version of Brazilian household food insecurity measurement scale - Pró-Saúde study

We present results of initial steps of the psychometric evaluation of a proposed modified version of the Brazilian Household Food Insecurity Measurement Scale aimed at assessing adults' recall of food insecurity at age 12. Data were obtained through self-administered questionnaires from civil servants at university campuses in Rio de Janeiro, who participated in the first and fourth waves of the longitudinal Pró-Saúde Study. We evaluated test-retest reliability (n=58), internal consistency, factor structure, convergent, discriminant validity (n=3,253). Test-retest reliability kappa coefficients were above 0.65; Cronbach's α coefficient was 0.84. Factor loadings were above 0.800. The composite reliability was above 0.90. The square root values of the Average Variance Extracted were positive and statistically significant. Household food insecurity during childhood was strongly associated with larger family size and several sociodemographic conditions at age 12: female head of household, residence in rural area or small town, worse standard of living, and insufficient food due to lack of money. This initial evaluation suggests good performance. Further investigation should include additional psychometric properties and other population contexts.

Perspective: The Importance of Water Security for Ensuring Food Security, Good Nutrition, and Well-being

Water security is a powerful concept that is still in its early days in the field of nutrition. Given the prevalence and severity of water issues and the many interconnections between water and nutrition, we argue that water security deserves attention commensurate with its importance to human nutrition and health. To this end, we first give a brief introduction to water insecurity and discuss its conceptualization in terms of availability, access, use, and stability. We then lay out the empirical grounding for its assessment. Parallels to the food-security literature are drawn throughout, both because the concepts are analogous and food security is familiar to the nutrition community. Specifically, we review the evolution of scales to measure water and food security and compare select characteristics. We then review the burgeoning evidence for the causes and consequences of water insecurity and conclude with 4 recommendations: 1) collect more water-insecurity data (i.e., on prevalence, causes, consequences, and intervention impacts); 2) collect better data on water insecurity (i.e., measure it concurrently with food security and other nutritional indicators, measure intrahousehold variation, and establish baseline indicators of both water and nutrition before interventions are implemented); 3) consider food and water issues jointly in policy and practice (e.g., establish linkages and possibilities for joint interventions, recognize the environmental footprint of nutritional guidelines, strengthen the nutrition sensitivity of water-management practices, and use experience-based scales for improving governance and regulation across food and water systems); and 4) make findings easily available so that they can be used by the media, community organizations, and other scientists for advocacy and in governance (e.g., tracking progress towards development goals and holding implementers accountable). As recognition of the importance of water security grows, we hope that so too will the prioritization of water in nutrition research, funding, and policy.

Governmental programmes associated with food insecurity among communities of descendants of enslaved blacks in Brazil

OBJECTIVE

To assess the access to government programmes and their association with food insecurity (FI) in families from quilombolas communities in Brazil.

DESIGN

An analysis of secondary data from the 2011 Quilombolas Census was performed in Brazilian territories. The Brazilian Household Food Insecurity Measurement Scale (Escala Brasileira de Insegurança Alimentar, EBIA) was used to assess the household FI status. The relationships of governmental programmes with the levels of FI were estimated using logistic regression models.

SETTING

Greater national survey census of food and nutritional security of the recognised Quilombolas Brazilian territories.

PARTICIPANTS

Totally, 8743 quilombolas families.

RESULTS

The prevalence of household FI was 86·1 % (moderate/severe FI: 55·9 %, 95 % CI 54·8, 56·9). After adjustment for socio-demographic variables, access to rural development programmes (Food Acquisition Program: OR: 0·6, 95 % CI 0·4, 0·8, P-value < 0·01) and health programmes (Center for Family Health Support: OR: 0·5, 95 % CI 0·5, 0·7, P-value < 0·001) is inversely and significantly associated with moderate/severe FI. The Brazilian conditional cash transfer programme (Bolsa Família) was associated with quilombolas families with moderate/severe levels of FI (OR: 3·3, 95 % CI 2·8, 4·0, P-value < 0·001).

CONCLUSIONS

The prevalence of FI was high among quilombolas families. Despite reduced participation in governmental programmes, rural development, agriculture and conditional cash transfer programmes are fundamental to the autonomy of quilombolas communities. In spite of the low participation, when families are able to access these programmes, the study revealed the importance of these initiatives in reducing the likelihood of severe levels of FI.

Validity of a 2-item screening tool to identify families at risk for food insecurity in Brazil

This manuscript aimed to develop a brief 2-item screening tool to identify Brazilian households that include families with children at risk for food insecurity. Psychometric analyses including sensitivity, specificity, positive and negative predictive value, accuracy, and ROC curves were used to test combinations of questions to determine the most effective screener to assess households at risk for food insecurity when compared to a gold standard scale. Participants included Brazilian National Survey of Demography and Health on Women and Children (PNDS) surveyed households with a valid Brazilian Food Insecurity Scale (EBIA) response. The sample included 3,920 households representing 11,779,686 households when expanded using PNDS sample weights. With overall prevalence of food insecurity at 21%, a Brazilian 2-item food-insecurity screen showed sensitivity of 79.31%, specificity of 92.95%, positive predictive value of 74.62%, negative predictive value of 94.5% and ROC area 86.13%. This screen also presented high convergent validity for children's nutrition and health variables when compared with the gold standard, the EBIA full scale. Based on its ability to detect households at risk for food insecurity, a 2-item screening tool is recommended for widespread adoption as a screening measure throughout Brazil, especially when rapid decision-making has been made fundamental, as under the COVID-19 pandemic. This screener can enable providers to accurately identify families at risk for food insecurity and promptly intervene to prevent or ameliorate adverse health and developmental consequences associated with food insecurity and swiftly respond to crises.

[Household availability of food based on the new classification of food and nutritional (in)security]

The scope of this research was to characterize the household availability of food based on the classification adopted in the new Brazilian food guide and to analyze its relationship with food (in)security. It involved a population-based, cross-sectional study conducted in 95 households in the State of Tocantins. Food (in)security was evaluated by means of the Brazilian Food Insecurity Scale. The household availability of food in the last 30 days was recorded and, subsequently, food was classified as in natura and/or minimally processed, processed and ultra-processed according to the new Brazilian food guide. The prevalence of food insecurity was 55.79%. It was found that the foods of the in natura and ultra-processed groups contributed the most to the household availability of food. There was a positive and significant relationship between the food security and food availability rates: milk, animal fat, canned food and cheese bread. The prevalence of food insecurity was high in this population group. In households with a higher level of food security, the availability of milk, animal fat, canned goods and cheese bread was significantly higher.

Unpacking the "black box" of global food insecurity and mental health

Food insecurity is a global concern. While it was once characterized mainly as a problem of undernutrition, it is now recognized that a person may be food insecure without experiencing hunger. Numerous studies have demonstrated that food insecurity is strongly related to poor mental health around the world, but the mechanisms that underpin that relationship remain poorly understood. One body of research from nutritional sciences posits that nutrient deficiency impacts brain function, producing symptoms of depression and anxiety. Another body of research from the social sciences posits that the social consequences of having to eat non-preferred foods or obtain food in socially unacceptable ways may compromise mental health through stress. This study was designed to clarify the mechanisms linking food insecurity and mental health using case studies in rural Brazil and urban Ethiopia. Working with samples consisting of about 200 adult household decision-makers (mostly female) recruited between 2015 and 2019 at each site, we tested for nutritional and social mediation of the food insecurity-mental health relationship using multivariable linear regression and mediation analysis. Our analyses found no evidence of mediation in either setting. Moreover, there was no association between nutritional status variables and food insecurity. These findings suggest that food insecurity likely impacts mental health directly through forms of basic needs deprivation, such as worrying about where one's next meal will come from, rather than by acting as a social signal or even by impacting nutritional status. These results underscore the power of basic-needs deprivation for impacting mental health.

Household income and loss of control eating in adolescence: Examining the role of food insecurity

Loss of control (LOC) eating is prevalent among adolescents and has been related to significant mental and physical health concerns. A growing body of research suggests that youth from lower income households are at risk for LOC eating. Food insecurity is an understudied contextual factor that may compound the risk for LOC eating in adolescents from low-income backgrounds. The present study sought to: 1) clarify the association between food insecurity and LOC eating among adolescents; and 2) examine whether household food insecurity moderated the association between income-to-needs and LOC eating. As part of a laboratory-based study, adolescents ages 12-17 (N = 60; 33% from low-income households; 53.3% female) completed the Eating Disorder Examination-Questionnaire to measure LOC eating. Parents reported the household food insecurity status and household income, used to calculate income-to-needs ratio. Higher household food insecurity was positively associated with adolescent LOC eating (b = 0.662, t(59) = 5.09, p < .01), after controlling for adolescent BMI percentile, race, ethnicity, biological sex, and age. Food insecurity significantly moderated the association between income-to-needs and LOC eating, ΔF(1,56) = 11.99, p < .01, with the interaction effect explaining an additional 12% of variance. Specifically, lower household income-to-needs was associated with greater LOC eating among adolescents at higher levels of household food insecurity. This finding expands upon prior work by highlighting specific socioeconomic factors that place youth from low-income backgrounds at even greater risk for negative health outcomes. Future research is needed to understand potential ways to intervene for adolescents to prevent future LOC eating in the context of food insecurity.

High prevalence of food insecurity, the adverse impact of COVID-19 in Brazilian favela

Objective:

To investigate food insecurity (FI) prevalence in two favelas in Brazil in the early weeks of the social distancing policy, from 27 March 2020 to 1 June 2020.

Design:

A cross-sectional study using an online questionnaire to elicit information on socio-economic and demographic characteristics, the types of stores visited to buy food, and FI screening. The FI experience was evaluated according to the Brazilian Food Insecurity Scale. Factors associated with moderate or severe FI were investigated using the logistic regression model.

Setting:

São Paulo city, Brazil.

Participants:

Totally, 909 householders.

Results:

Eighty-eight per cent of the households included young women working as cleaners or kitchen assistants and in sales services. One-fifth of the participants were involved in the federal cash transfer programme, called Bolsa Família. There were 92 % households with children. The most frequent experience reported was uncertainty about food acquisition or receiving more (89 %), eating less than one should (64 %), not being able to eat healthy and nutritious food (46 %), and skipping a meal (39 %). Forty-seven per cent of the participants experienced moderate or severe FI. Factors associated with moderate and severe FI were low income, being a Bolsa Família recipient, having a low level of education and living in a household without children.

Conclusions:

Half of the participants experienced moderate or severe FI, and almost 10 % experienced hunger. Our data suggest that families with children were at a lower risk of moderate to severe FI. It is possible that nationally established social programmes such as Bolsa Família were protecting those families.

Maternal mental health modifies the association of food insecurity and early child development

We examined the association between household food insecurity and early child development and whether or not maternal depression and anxiety modifies this association. The cross-sectional study included 468 mother-infant pairs recruited at primary health centers of the Federal District, Brazil. Mothers answered a questionnaire that evaluated early child development (outcome), household food insecurity (independent variable), maternal depression and trait anxiety (effect modifiers). Variables were collected with validated questionnaires for the Brazilian population. Pearson's χ2 test and logistic regression analyses were conducted. Infants who lived in a moderate or severe food insecure household had 2.52 times (95% confidence interval [CI] [1.13, 5.65]) the odds of having early child development delays compared with infants in secure households. Maternal depression and anxiety modified the strength of association between household food insecurity and early child development, which is an innovative finding. Among infants with depressed mothers, those experiencing mild (adjusted odds ratio [aOR] 3.33, 95% CI [1.17, 9.46]) and moderate/severe household food insecurity (aOR 10.13, 95% CI [2.18, 47.10]) had higher odds of having early child development delays, compared with infants in food secure households. Among infants with both anxious and depressed mothers, these associations were even stronger for mild (aOR 4.69, 95% CI [1.41, 15.59]) and moderate/severe household food insecurity (aOR 16.07, 95% CI [2.70, 95.66]). In conclusion, household food insecurity is a risk factor for early child development delays, and this association is modified by maternal depression and anxiety. Future studies should evaluate the impact of intervention packages that address maternal depression and anxiety and household food insecurity on preventing early child development delays.

Factors associated with food security in households in the urban area of the state of Tocantins, Northern Brazil

OBJECTIVE

To evaluate the factors associated with food insecurity in families living in the urban area of Tocantins/Brazil.

METHODS

This is a population-based cross-sectional study conducted in the urban area of 22 municipalities in the 8 microregions of the state. A semi-structured questionnaire was applied to the head of household to obtain socioeconomic and demographic data, and the Brazilian Food Insecurity Scale (EBIA) was used to assess food insecurity at home. The anthropometric assessment of the residents was made by measuring weight, height/length and waist circumference. Multinomial logistic regression was performed to assess the association of food insecurity with individual/household variables, and Pearson's chi-square test was used to compare whether there was a difference in the prevalence of food insecurity between microregions and between families with and without individuals under 18 years.

RESULTS

A total of 596 households were evaluated, of which 63.4% were in a food insecurity situation. The final model of the multivariate analysis showed that low head-of-household schooling, low per capita income, receiving social assistance benefits and lack of clean drinking water in the household were associated with food insecurity (p < 0.05).

CONCLUSIONS

The findings of this study reveal the high prevalence of food insecurity in the families studied and their associated factors, showing the need for local actions and public policies to improve health conditions, education and income of the population, and consequently, improve the scenario of food and nutritional insecurity in the state.

Syndemics theory must take local context seriously: An example of measures for poverty, mental health, and food insecurity

Syndemics theory has provided insight into the ways that disease states and social adversity interact in marginalized populations to further disempower these groups. Yet, until recently, scholars have not identified how we might actually recognize and measure a syndemic, as opposed to a situation where there are multiple but non-interacting diseases present in a population. As researchers like those included in this special issue develop new methods for assessing syndemic interactions in diverse global populations, this short communication argues for the value of locally relevant measures. Poverty, mental health, food insecurity, and type 2 diabetes are used to illustrate the assessment of a potential syndemic from a locally grounded perspective. The discussion emphasizes the insights locally adapted measures can add and what information would be lost without their use.

Association between iron deficiency anaemia and complementary feeding in children under 2 years assisted by a Conditional Cash Transfer programme

OBJECTIVE

To evaluate the association between Fe deficiency anaemia (IDA) and complementary feeding in children under 2 years old assisted by the Conditional Cash Transfer programme, Bolsa Família (BFP).

DESIGN

Cross-sectional study. Data were obtained through a standardised form, questionnaire to assess the eating habits of children under 2 years of age, capillary Hb (HemoCue®) and the Brazilian Household Food Insecurity Measurement Scale. Associations were calculated using hierarchical Poisson regression, adjusted at the last level by socio-economic, demographic and environmental variables from previous hierarchical levels.

SETTING

Six municipalities from the State of Alagoas, Brazil.

PARTICIPANTS

Children aged 6-24 months assisted by BFP.

RESULTS

A total of 1604 children were evaluated, among whom 58·1 % had anaemia. A higher number of food groups consumed (prevalence ratio (PR) = 0·97; 95 % CI 0·95, 0·99; P = 0·009), the consumption of dairy (PR = 0·86; 95 % CI 0·79, 0·84; P = 0·001) and meat (PR = 0·90; 95 % CI 0·83, 0·99; P = 0·030) in addition to bottle feeding (PR = 0·88; 95 % CI 0·82, 0·96; P = 0·004) were associated with a lower prevalence of IDA.

CONCLUSIONS

IDA is still a serious public health problem in children under 2 years old assisted by BFP in Alagoas. We highlight the importance of promoting complementary feeding based on a diversified dietary intake, as well strengthening prophylactic supplementation programmes to increase children's adherence in conjunction with the implementation of food and nutrition education to help reduce the prevalence of this condition.

Association between the consumption of ultra-processed foods and the practice of breast-feeding in children under 2 years of age who are beneficiaries of the conditional cash transfer programme, Bolsa Família

Objective:

To evaluate the association between the consumption of ultra-processed foods (UPF) and the practice of breast-feeding in children under 2 years of age assisted by the conditional cash transfer programme, Bolsa Família Programme (PBF).

Design:

A cross-sectional study. The consumption of UPF and the practice of breast-feeding were assessed using a structured 24-h recall. Associations were calculated using hierarchical Poisson regression, adjusted at the last level by socio-economic, demographic and environmental variables from previous hierarchical levels.

Setting:

Six counties from the state of Alagoas, Brazil.

Participants:

Children aged 6−24 months, assisted by PBF.

Results:

A total of 1604 children were evaluated, 11·7% of whom were overweight, and most had consumed UPF (90·6%) in the last 24 h. The most consumed UPF were biscuits, chocolate milk and baby food with 74·8, 66·8 and 24·9%, respectively. Through multivariable analysis, an association was found between lower consumption of UPF in the continuation of breast-feeding until the second year of life (prevalence ratio (PR) 0·91, 95 % CI 0·86, 0·96) and in the first year of life (PR 0·93, 95 % CI 0·88, 0·99).

Conclusions:

It was found that the studied population had a high consumption of UPF, which harmed continued breast-feeding. We highlight the importance of strengthening public policies aimed at the promotion, protection and support of breast-feeding and healthy complementary feeding aimed at populations that have difficulties in physical and economic access to a healthy and adequate diet.

Food insecurity is associated with compromised dietary intake and quality among Lebanese mothers: findings from a national cross-sectional study

OBJECTIVE

Examine the associations between household food insecurity (HFI) with sociodemographic, anthropometric and dietary intakes of mothers.

DESIGN

Cross-sectional survey (2014-2015). In addition to a sociodemographic questionnaire, data collection included the validated Arabic version of the Household Food Insecurity Access Scale, which was used to evaluate HFI. Dietary intake was assessed using 24-h dietary recall of a single habitual day, and maternal BMI was calculated based on weight and height measurements. Associations between HFI and maternal dietary intake (food groups, energy and macronutrients' intake) were examined. Simple and multiple logistic regression analyses were conducted to explore the associations between HFI status with odds of maternal overweight and measures of diet quality and diversity (Healthy Eating Index (HEI) and Minimum Dietary Diversity for Women of Reproductive Age (MDD-W)).

SETTING

Lebanon.

PARTICIPANTS

Mothers, nationally representative sample of Lebanese households with children (n 1204).

RESULTS

HFI was experienced among almost half of the study sample. Correlates of HFI were low educational attainment, unemployment and crowding. Significant inverse associations were observed between HFI and dietary HEI (OR 0·64, 95 % CI 0·46, 0·90, P = 0·011) and MDD-W (OR 0·6, 95 % CI 0·42, 0·85, P = 0·004), even after adjusting for socioeconomic correlates. No significant association was observed between HFI and odds of maternal overweight status.

CONCLUSIONS

HFI was associated with compromised maternal dietary quality and diversity. Findings highlight the need for social welfare programmes and public health interventions to alleviate HFI and promote overall health and wellbeing of mothers.

Food Insecurity during Pregnancy in a Maternal-Infant Cohort in Brazilian Western Amazon

The aim of this study was to determine the prevalence and analyze the factors associated with food insecurity during gestation in a maternal-infant cohort in Brazilian Western Amazon. A population-based cross-sectional study was conducted with parturients from a maternal-infant cohort in Rio Branco, located in the Western Brazilian Amazon. The dependent variable food insecurity (FI) was obtained through the Brazilian Scale of Food Insecurity, and associated factors were identified through multiple logistic regression. The prevalence of FI in pregnancy was of 34.8%. Regarding severity, the prevalence of mild food insecurity was 24.6%, moderate food insecurity was 4.8%, and severe food insecurity was 5.4%. The factors directly associated with FI were the presence of open sewage in the peridomestic environment; belonging to the lower economic classes; being an income transfer program beneficiary, while the factors inversely associated with FI were schooling equal to or greater than 8 years; having a partner; primigestation; and regular consumption of fruits and vegetables during pregnancy. These findings reinforce the need for the ratification of actions aimed at the domestic economy in the income transfer programs and the development of actions of food and nutritional education in the gestational period.

Exploring food insecurity and obesity in Dutch disadvantaged neighborhoods: a cross-sectional mediation analysis

BACKGROUND

Food insecurity is related to risk of adverse health outcomes such as obesity, but the explanatory factors underlying this association are still unclear. This study aimed to assess the association between food insecurity and obesity, and to explore potential mediation by sociodemographic and lifestyle factors.

METHODS

This cross-sectional study was conducted among 250 participants in a deprived urban area in the Netherlands. Data on sociodemographic and lifestyle factors, food insecurity status and diet quality were collected using questionnaires. Diet quality was determined based on current national dietary guidelines. BMI was calculated from self-reported height and weight. Regression analyses were performed to explore the association between food insecurity and BMI status. Mediation analyses were performed to estimate the total-, direct-, and indirect effect and proportion of total effect mediated of the food insecurity-obesity association.

RESULTS

The overall prevalence of food insecurity was 26%. Food insecurity was associated with obesity (OR = 2.49, 95%CI = 1.16, 5.33), but not with overweight (OR = 1.15, 95%CI = 0.54, 2.45) in the unadjusted model. The food insecurity-obesity association was partially mediated by living situation (proportion mediated: 15.4%), diet quality (- 18.6%), and smoking status (- 15.8%) after adjustment for other covariates.

CONCLUSIONS

The findings of this study suggest an association between food insecurity and obesity. Living situation, diet quality and smoking status explained part, but not all, of the total association between food insecurity and obesity. Future longitudinal studies are warranted to examine the temporal order of the food insecurity-obesity association and potential mediators in this relationship. In addition, food insecurity and its potential consequences need to be taken into account in obesity prevention programs and policies.

The association of maternal plant-based diets and the growth of breastfed infants

Background: Studies are needed to further understand how different plant-based dietary patterns of mothers relate to infant growth. Thus, we investigated the association between maternal plant-based diets and infant growth in breastfed infants during the first 4 months of life.

Methods: This cross-sectional study included 290 Iranian mothers and infants. Maternal dietary intake was assessed using a 168-question validated semi-quantitative food frequency questionnaire (FFQ). Three plant-based diet indices (PDIs) were then created to evaluate dietary intakes. Eighteen food groups were classified in three main categories by scoring method: wholeplant diet, healthy plant diet, and animal and unhealthy plant diet.

Results: Participants in the top tertile of unhealthy PDI (uPDI) had a lower intake of potassium,phosphorus, zinc, magnesium, calcium, folate and vitamin C, B1, B2, and B3. The upper tertileof uPDI was associated with stunting at 4-month in infants (uPDI: odds ratio [OR] = 3.27, 95%CI= 1.32, 8.10). There were no significant associations between plant-based diet scores and anthropometric indices, including weight, weight status and head circumference (P > 0.05).

Conclusion: In conclusion, higher adherence to uPDI may be associated with stuntingamong Iranian infants. Other PDIs were not associated with anthropometric measures. Future studies are needed to further understand the association between plant-based diets and infant growth.

Suicidal thought in southern Brazil: Who are the most susceptible?

BACKGROUND

Suicide is one of the leading causes of death among adolescents and young adults worldwide. However, risk factors for suicidal thoughts might change across cultures and contexts. We aimed to assess the prevalence and associated factors of suicidal thought among adults in a southern Brazilian city.

METHODS

This population-based cross-sectional study used a multistage sampling procedure to evaluated individuals with 18 years or more, living in a southern city in Brazil. We collected suicidal thought using a question from the Patient Health Questionnaire-9. In addition, we collected information on sociodemographic, behavioral, and health variables, through a questionnaire using standardized and validated instruments. We calculated prevalence ratios (PR) using Poisson Regression models with robust adjustment of the variance.

RESULTS

We collected information from 1295 individuals, 6.6% were positive for suicidal thought. In multivariate analysis, factors independently associated with suicidal thoughts included: being a woman, poor, reporting current tobacco use, having household food insecurity, having three or more morbidities, being in the upper tertile of the stress scores, having had a depression diagnostic in the last year and sadness.

LIMITATIONS

We cannot say that the associations found are causal. Suicidal thoughts were assessed from a single question.

CONCLUSION

Suicidal thought is a prevalent condition, most likely associated with being a woman, having worst socioeconomic conditions, a poorer health, a higher stress, using tobacco and having depression and/or sadness.

Associação entre insegurança alimentar e níveis de hemoglobina e retinol em crianças assistidas pelo Sistema Único de Saúde no Município do Rio de Janeiro, Brasil

Neste trabalho foi analisada a associação entre insegurança alimentar e níveis de hemoglobina e retinol em crianças de 6 a 59 meses de idade. Trata-se de um estudo seccional, realizado em 2014, com amostra representativa da população de crianças nessa faixa etária, atendidas em unidades básicas de saúde do Município do Rio de Janeiro, Brasil. Para a análise dos níveis de insegurança alimentar foi utilizada a Escala Brasileira de Insegurança Alimentar e, para a determinação de hemoglobina e de retinol sérico, foi realizada a punção venosa. A associação entre as variáveis foi avaliada por intermédio de modelos de regressão quantílica. Do total de crianças estudadas, 40,3% apresentavam insegurança alimentar e as prevalências de anemia e de deficiência de vitamina A foram 13,7% e 13%, respectivamente. Os resultados do estudo revelaram associação inversa, estatisticamente significativa, entre insegurança alimentar leve e níveis de retinol. Para os demais níveis de insegurança alimentar (moderada e grave), os resultados também sugerem a presença de associação inversa para hemoglobina e, quanto aos níveis de retinol, as estimativas pontuais parecem menores em crianças com insegurança alimentar grave, entretanto, estas estimativas não foram estatisticamente significativas. Esses resultados sugerem que a insegurança alimentar pode estar associada com carências de micronutrientes em crianças menores de 5 anos.

Relationship between social indicators and food insecurity: a systematic review

ABSTRACT: Introduction: The relationships between the social indicators (SIs) that determine food insecurity (FI) have not been described yet. This systematic review aims to identify which SIs are associated with FI in Brazilian households and how these relationships are explained. Methods: The research protocol was registered on the International Prospective Register of Systematic Reviews (PROSPERO - CRD42018106527). Three independent researchers performed the search in the Latin American and Caribbean Health Sciences Literature (LILACS) and National Library of Medicine (PubMed) databases (June/2018). The study included articles that used the Brazilian Household Food Insecurity Measurement Scale (Escala Brasileira de Insegurança Alimentar - EBIA) to assess FI and that evaluated the association between SIs and FI. Results: We included 18 articles in this review. The Kappa concordance index between the researchers was 0.72 (95%CI 0.42 - 1.00). Most articles were cross-sectional and used multivariate regression for the statistical analysis. At least one income-related SI had a significant association with FI, and, in most studies, they presented the highest values of association measures. We organized the authors’ explanation about the relationships between SIs and FI in a conceptual model. The study identified three possible justifications for the association between SIs and FI: direct relationship, relationship mediated by income, or relationship mediated by another SI and income. Conclusion: Income assumed a central role in the mediation between several SIs and FI. However, the analysis methods of the studies did not allow us to investigate this mediation. Therefore, improving data analysis to isolate and understand the effect of SIs on FI is still necessary.
