The association between food insecurity and obesity, a body shape index and body roundness index among US adults

Research has established a positive association between food insecurity and obesity, typically assessed by body mass index (BMI); However, studies examining the relationship between food insecurity and measures of body fat content and distribution are lacking. The aim of this study was to examine the association between food insecurity and obesity ([BMI] ≥ 30 kg/m2) and body fat indicators assessed by body roundness index ([BRI] > 6.72) and a body shape index ([ABSI] > 0.08). This is a cross-sectional study using NHANES data 2007–2020. Household food security was assessed by U.S. Food Security Survey Module questionnaire. Multivariable-adjusted binary logistic regression analyses were used to calculate odds ratios and 95% CIs. Compared to those with full food security, the adjusted ORs for obesity were 1.28 (95% CI:1.18, 1.39), 1.40 (95% CI:1.28, 1.53), and 1.43 (95% CI:1.30, 1.57) for those with marginal, low and very low food security, respectively. The corresponding ORs for high BRI were, respectively, 1.39 (95% CI:1.26, 1.52), 1.50 (95% CI:1.36, 1.66), and 1.60 (95% CI:1.43, 1.78). Similar results were observed for ABSI. The analyses of BMI suggested a potential sex difference, as significant associations were found in women, but not in men. This study confirms previous evidence of the positive association between food insecurity and obesity among US adults.

A qualitative exploration of the COVID-19 pandemic on health and nutrition behaviours during the first 1000 days in Sri Lanka.

This study sought to understand reported impacts of the COVID-19 pandemic on maternal and child health and nutrition behaviours during the first 1000 days of life. This qualitative and participatory substudy was embedded within mixed methods formative research conducted during 2020-2022 across two urban, three rural and one estate sector site in Sri Lanka. Semi-structured interviews among caregivers of children aged 6-23 months (n = 34), influencers of caregivers, such as health workers (n = 37), leaders (n = 10) and pregnant women (n = 20) were conducted. Participatory workshops (n = 14) triangulated interview findings. Interview data were analyzed to identify salient themes using Dedoose. Numerical data from voting conducted in workshops were summed and triangulated with interview data. Findings suggest that the COVID-19 pandemic and imposed restrictions shaped maternal and child health and nutrition behaviours through a complex interplay of factors. Imposed restrictions and changes to the food system contributed to temporary unemployment for wage workers and reduced purchasing power to maintain food security for vulnerable households. While deciding whether to seek care, fears of infection prevented usual care-seeking decisions. Also, reduced incomes and disrupted public transportation made transport to health care facilities for antenatal care services difficult. Once women reached facilities, medical services and quality of care were negatively impacted. Implementing expanded community-based services during home visits focused on the first 1000 days and beyond was one effective strategy to maintain maternal and child health and nutrition during the early pandemic in Sri Lanka.

Participation in artisanal diamond mining and food security: A case study of Kasai Oriental in DR Congo

Abstract The high prevalence of food insecurity and malnutrition in Kasai Oriental, Democratic Republic of the Congo, prompted an investigation into the complex relationship between household livelihood activities and food security. Despite many rural households relying on subsistence farming, this alone may not ensure improved food security in Kasai Oriental. Consequently, non-farm sectors like artisanal mining offer a potential solution to address food insecurity among rural households. The aim of this study is to explore the association between engagement in artisanal diamond mining, food insecurity, and children’s nutritional status in Kasai Oriental. The research utilizes household cross-sectional data collected between November and December 2022. Fixed effects and Instrumental variable models were employed to address household heterogeneity and potential endogeneity related to participation in artisanal diamond activities. The regression results reveal a significant relationship between participation in artisanal diamond mining and food security. This implies that participation increases households’ cash, enabling them to access sufficient food and potentially mitigating the risk of falling into food insecurity. However, involvement in artisanal mining has not shown a significant association with children’s malnutrition. These findings call for further research on “hidden hunger.” Policies aiming to encourage and formalize artisanal diamond mining should integrate specific extension services and inform rural households about hidden hunger.

Building Representative State Groupings in an Input-Output Model for the Development of an Economic Impact Calculator for Nutrition Incentive Programs

Eating a diet high in fruits and vegetables is associated with a reduction in the risk of chronic diseases such as obesity, cardiovascular disease, Type 2 diabetes, hypertension, asthma, depression, and mental illness, yet few low-income adults meet these recommendations. Nutrition incentive programs have emerged over the last decade to offer incentives to food-insecure households to purchase more fruits and vegetables. Although the goal of the program is to increase the consumption of fresh fruits and vegetables, defenders of nutrition incentive programs increasingly want to document economic impacts of their programs but often lack the resources to do so. Rather than these programs spending their scarce resources on conducting studies, this research created a rigorous, yet easy to use tool that U.S.-based practitioners operating nutrition incentive programs can use to estimate the economic impact of their programs, including incentive redemptions at both farm-direct and brick-and-mortar businesses.

Is seed aid distribution still justified in South Sudan?

Seed aid—or free distribution of seeds to farmers—is a popular intervention to simultaneously reduce food insecurity and dependency on food aid in fragile countries. However, seed aid distribution also has the potential to hinder or distort the development of local seed markets. In this study we analyze the targeting and impact of seed aid across the green belt (cutting across the southern/equatorial states) of South Sudan. Using a primary and unique dataset on 1,990 farm households, we find that seed aid is widely rather than selectively distributed. Almost a third of farm households receive seed aid despite the general availability of locally recycled seed varieties. Seed aid distribution does not seem to favor particularly poor, vulnerable and food insecure households, but those that are embedded in community networks, organizations and institutions. Using a double robust methodology based on Inverse Probability Weighted Regression Adjustment (IPWRA), we also find that the adoption of seed aid by farm households does not result in increased maize production, as it is neither associated with agricultural intensification nor with the expansion of cultivated land. Seed aid seems to substitute rather than supplement local seed varieties. These findings emphasize a lack of intentionality in seed aid distribution. Still, it must be noted that the effectiveness of seed aid distribution may be greater outside our study area, above the green belt, where conflicts and natural disasters remain more frequent and intense, and where farmers are more likely to be seed insecure. But overall, this study supports the widespread perception that South Sudan is ready for a transition towards a market-based seed distribution system.

Water insecurity is associated with intimate partner violence among female adolescents and youth but not males in rural Tanzania: A cross-sectional study

ABSTRACT Food insecurity increases intimate partner violence (IPV), but less is known about water insecurity (WI) and IPV. We examined the association between household WI and IPV among adolescents and youth in the Mbeya and Iringa regions of Tanzania. The cross-sectional sample comprised 977 males and females aged 18–23 years living in rural, impoverished households. We conducted multivariate logistic regression analyses to estimate the association between experiences of WI [measured by the Household Water Insecurity Experiences (HWISE-4) Scale] and physical and/or emotional IPV (measured by an adapted Conflict Tactics Scale). Overall, WI (HWISE ≥4) was associated with 74% higher odds of any IPV (marginal effects (ME) of 7.8 percentage points (pp)), compared to those not WI. Among females (but not males), WI was associated with 3-fold higher odds of any IPV (OR = 3.00; 95% CI: [1.52, 5.94]; ME = 14 pp). Compared to non-WI females, WI females had 5- and 2-fold higher odds of IPV (ME = 30.8 and 11.3 pp) among the ever married and never married sub-samples, respectively. The association between WI and IPV among females was attenuated (OR = 1.93; 95% CI: [0.93, 3.97]) when adjusting for household food insecurity. Ameliorating water insecurity is a promising avenue for IPV reduction.

Faith and food in rural Malawi: an investigation into the sociocultural determinants of household food security

ABSTRACT This study demonstrates that religion and culture play a substantial role in shaping the dietary preferences of rural Malawians. Therefore, it is imperative that cultural and specifically religious factors are given due consideration when devising strategies aimed at alleviating household food insecurity and promoting food security. Despite years of substantial agricultural output, household food insecurity remains a persistent problem, primarily due to sociocultural factors that influence how food is consumed within households. It has been proven that social activities such as weddings, initiation ceremonies, and funerals can significantly impact a household’s food status. The study underscores the need for policymakers to incorporate cultural factors into food security interventions to produce more effective and equitable policies.

Does livelihood diversification improve food security among rural households?: evidence from Ghana

ABSTRACT Livelihood diversification (LD) is crucial for rural households due to increasing climate variability and declining farm incomes in the global south. Literature has extensively documented the benefits of LD in emerging economies. However, there is still a gap in the econometric evidence of LD on the food security of rural households in Ghana. This study addresses this gap by examining the factors that influence LD using the Ghana Living Standards Survey (GLSS 7) data collected from 133 rural households in Northern Ghana. Results from the censored Tobit regression model, multiple linear regression, and Simpson Diversification Index (SDI) indicated that diversification averaged 0.313 and ranged from 0.000 to 0.709 (zero to 70.9%). Total food expenditures (TFE) measured as a proxy of food security declined at low levels of diversification. Beyond the diversification level of 0.480, total food expenditure increased steadily. The findings revealed that only 24.6% of the households had diversification scores higher than the turning point of 0.480. The Tobit model also showed that remittance income, technical education, household size, marital status, access to extension services, and ownership of mobile phones were significant drivers of LD. The findings have demonstrated that LD improves food security in rural Ghana.

Household Food Insecurity Is Associated with Parental Perceptions of and Student Participation in School Meals.

School meals are an important source of nutrition for children and have been found to help mitigate food insecurity. This study evaluated the association between food insecurity and school meal participation and whether parental perceptions about school meals differ by food security status. In May 2022, 1110 Californian parents of K-12 students shared their perceptions about school meals, including meal quality, healthiness, stigma, and benefits, as well as their child's participation in school meals, in an online survey. Household food security was determined using the USDA 6-item module. Logistic and Poisson regression models were used for analysis. The prevalence of household food insecurity was 56.2% (69.6% in households of students eligible for free meals, 55.9% in reduced-price, and 38.3% in non-eligible). Many of the reported benefits of school meals (saving families money and time) were equally highly endorsed by parents with and without food insecurity (p > 0.05). Parents reporting food insecurity had less favorable perceptions of school meals and perceived more stigma (p < 0.05). Food insecurity was positively associated with breakfast participation, especially among elementary school students and students not eligible for free or reduced-price meals (FRPMs) (p < 0.05). Food insecurity is prevalent among California families with school-age children, even in families not eligible for federal FRPMs. Food-insecure households have more negative perceptions of school meals and experience more stigma, though they also report higher breakfast participation. Improving school meal quality and appeal, ensuring parents are familiar with meal quality and healthfulness, and reducing stigma may ease food insecurity while improving children's health.

Mental health, water, and food: Relationships between water and food insecurity and probable depression amongst adults in Mexico

BackgroundWater and food insecurity often co-occur, and have independently been identified as potential risk factors for poor mental health. Their interlinkages are only just beginning to be explored; even less is known about how the relationships vary by gender. Understanding the independent associations of water and food insecurity with mental health, as well as their joint effects, can help identify which interventions might be most appropriate for improving health. MethodsWe explored how probable depression covaried with water and food insecurity using nationally representative data from the Mexican National Health and Nutrition Survey 2021 (ENSANUT 2021, n = 13,126). Cross-sectional data were collected on household water, food insecurity, and probable depression amongst adults were collected. We used multivariable logistic regression models to examine the association of water and food insecurity with moderate-to-severe probable depression: and we stratified the models by sex. ResultsHousehold water insecurity was associated with higher odds of probable depression amongst women (1.37 OR, CI: 1.13–1.66) and men (1.30 OR, CI: 0.92–1.83). When controlling for household food insecurity, the association between probable depression and water insecurity was no longer important, however, household food insecurity was associated with higher odds of probable depression. Those experiencing joint water and food insecurity had the highest odds of probable depression (2.70 OR, CI: 2.13–3.40). The associations between water insecurity, food insecurity and mental health did not differ by sex. ConclusionConcurrent water and food insecurity increase the likelihood of probable depression amongst both men and women. Strategies to mitigate both resource insecurities could improve mental health.

Analysis of co-operative irrigation farming and household food security in Africa: A PRISMA model approach

This study provides a comprehensive bibliometric analysis of the relationship between co-operative irrigation farming and household food security in Africa. The research aims to identify key studies, authors, and thematic clusters, analyse the geographical distribution of research efforts, and evaluate the impact of co-operative irrigation farming on food security indicators. Utilizing the PRISMA model, data were systematically gathered from peer-reviewed publications indexed in the Dimensions database, focusing on materials published between 2019 and 2023. The study employed both bibliometric and descriptive-quantitative methodologies to analyse the data. The results reveal a significant positive impact of co-operative irrigation farming on improving household food security across various regions in Africa. The findings highlight the need for targeted policy interventions and sustainable agricultural practices that support co-operative irrigation efforts. A growing scholarly attention toward co-operative irrigation farming and household food security in recent years reveals a potentiality in finding a sustainable solution to food insecurity challenge. These insights are essential for shaping future research and informing policies aimed at enhancing food security through co-operative farming models in the African context.

Good Friends and Good Neighbors: Social Capital and Food Insecurity in Families with Newborns

To examine the association between social capital and household food insecurity among US families with newborns. This cross-sectional analysis used enrollment data from 881 newborn-caregiver dyads at six geographically-diverse US academic sites enrolled in the Greenlight Plus Trial, a comparative effectiveness trial to prevent childhood obesity. Ordinal proportional-odds models were used to characterize the associations of two self-reported measures of social capital: 1) caregiver social support and 2) neighborhood social cohesion, with household food insecurity after controlling for sociodemographic characteristics. Among 881 newborn-caregiver dyads (49% Hispanic, 23% non-Hispanic white, 17% non-Hispanic Black; 49% with annual household income <$50,000), food security was high for 75%, marginal for 9%, low for 11% and very low for 4%. In covariate-adjusted analyses, caregivers with a low social support score of 18 had five times the odds (aOR=5.03 95%CI=3.28-7.74) of greater food insecurity compared with caregivers with a high social support score of 30. Caregivers with a low neighborhood social cohesion score of 10 had nearly three times the odds (aOR=2.87 95%CI 1.61-5.11) of greater food insecurity compared with caregivers with a high neighborhood social cohesion score of 20. These associations remained robust when both social capital measures were included in one model. Caregiver social support and neighborhood social cohesion each appear to be inversely associated with food insecurity among US families with newborns. Longitudinal research is needed to determine the directionality of these relationships and whether improving social capital for families with young children reduces household food insecurity.

Smallholder Farmers’ Climate Change Adaptation Strategies and Their Effect on Household Food Security: Evidence from KwaZulu-Natal, South Africa

Climate change poses a significant risk to the long-term viability of smallholder agriculture in developing countries. Climate change has a direct effect on agricultural output, ultimately impacting the food security of smallholder farmers. However, the link between climate change and food security in developing countries is underexplored. This article investigates the effect of climate change adaptation strategies on household food security. A survey was conducted among 400 smallholder farmers in the uMkhanyakude district of KwaZulu-Natal using a stratified random sampling procedure. Survey data were analysed using descriptive statistics. The findings indicate that factors such as access to credit, access to government funding, and participation in agricultural groups play an important role in supporting adaptation to climate change. Adaptation to climate change is associated with reduced levels of food insecurity. These results underscore the important role of climate change adaptation in enhancing household food security. The study recommends that programmes that target smallholder farmers should focus on enhancing the adaptive capacity of smallholder farmers.

Investigating the mediating role of physical activity within the association between food insecurity and BMI

Food insecurity is linked with obesity and while the mechanisms behind this association are complex, lower levels of leisure-time physical activity in those with food insecurity may contribute to this. Individual-level factors (such as concerns of performing physical activity) may partly determine levels of physical activity within individuals with food insecurity, as such individuals may seek to minimise their levels of physical activity in order to preserve energy. Using the Food Insecurity Physical Activity Concerns Scale (FIPACS) (used to measure concerns of performing leisure-time physical activity, focusing on factors specific to food insecurity), the current study investigated whether the association between household food insecurity and body mass index (BMI) is explained by a mediation pathway of FIPACS scores and leisure-time physical activity. We also investigated whether the association between food insecurity and FIPACS scores is moderated by nutrition knowledge. Participants (N = 329, food insecure = 55) completed an online survey consisting of the FIPACS, the International Physical Activity Questionnaire long-form (IPAQ), the Diet, Disease, and Weight management sub-section of the General Nutrition Knowledge Questionnaire, a measure of diet quality, and self-reported BMI. Findings revealed that FIPACS scores and leisure-time physical activity did not mediate the association between food insecurity and BMI (b < .01, SE = 0.01). Additionally, nutrition knowledge did not moderate the association between food insecurity and FIPACS scores (b = -0.09, SE = 0.08). Findings suggest that concerns of performing physical activity in the context of food insecurity are unrelated to leisure-time physical activity, and that these two factors do not explain the association between food insecurity and BMI. Future research should investigate other factors in the link between food insecurity, physical activity, and BMI.

A cross-sectional study of associations between the 13C-sucrose breath test, the lactulose rhamnose assay, and growth in children at high risk of environmental enteropathy

BackgroundEnvironmental enteropathy’ (EE) is common among children who are highly exposed to enteric pathogens in low-resource settings. We optimised and validated a stable isotope-based breath test of intestinal sucrase activity (13C-SBT) as a non-invasive test of carbohydrate digestion and metabolism. ObjectivesThe primary objective of this study was to assess the relationship between the 13C-SBT and the lactulose/rhamnose ratio (LR) and growth in children. Secondary objectives were to assess the relationship between the 13C-SBT and additional biomarkers of EE. We also characterised the relationship between the 13C-SBT and child sex anddietary diversity, and household socioeconomic status and food security. MethodsIn this cross-sectional study, 12-to-15-month-old children were recruited in Bangladesh, India, Kenya, and Peru. Children were assessed with a 4-hour 13C-SBT and a 90-minute LR test. Plasma was collected for the determination of citrulline and the kynurenine/tryptophan ratio. Length and weight were measured, and other variables were assessed through questionnaires. For a subset of children, anthropometry was re-measured after three months. inear regression was used to examine associations corresponding to each objective. ResultsThree sites generated 13C-SBT breath curves that enabled pooled analysis. Differences in 13C-SBT breath curves, LR ratios, and other EE biomarkers were observed between sites. No associations were observed for 13C-SBT summary measures and LR, or child growth (e.g., association between LR and cumulative percent dose recovered at 90 minutes (cPDR90): -0.39, 95%CI: -1.79, 0.70). Length-for-age and weight-for-age were positively associated with the time to 50% of dose recovered (T50) (0.05, 95%CI: 0.01, 0.09, and 0.05, 95%CI: 0.02, 0.07, respectively), and dietary diversity was associated with T50 and cPDR90(-0.10, 95%CI: -0.18, -0.02 and 2.67, 95%CI: 0.47, 4.88, respectively). ConclusionsIn children at risk of EE there were no associations between the 13C-SBT, LR or other EE biomarkers encompassing different pathophysiological domains of EE.
