Project description:Among rural families, rates of both child obesity and household food insecurity (FI) are higher compared to non-rural families. These disparities result from a complex interplay of social and environmental conditions that influence behavior. The Transtheoretical Model suggests individual readiness to change underlies success in modifying obesity-preventing behaviors; however, whether an association between readiness to change obesity-related behaviors and FI status among rural families exists is unknown. We examined the association between readiness to change family-level nutrition and physical activity (PA) behaviors that predict child obesity and family FI status within a sample of rural families to better understand these relationships. Families (n = 144) were recruited from six rural Oregon communities in 2013. Families completed a FI screener and the Family Stage of Change Survey (FSOC), a measure of readiness to change family-level nutrition and PA behaviors associated with obesity. Demographic differences by FI status were explored, and regression was applied to examine relationships between FI and FSOC scores, adjusting for relevant covariates. Among FI families (40.2%), more were non-white (77.8% vs. 22.2%; p = 0.036) and had lower adult education (30.4% vs. 11.8% with > high school degree; p = 0.015) compared to non-FI families. After adjusting for education, race, ethnicity, and eligibility for federal meal programs, readiness to provide opportunities for PA was lower among FI families (p = 0.002). These data highlight a need to further investigate how food insecurity and low readiness to provide PA opportunities, i.e. "physical activity insecurity" may be contributing to the higher obesity rates observed among rural children and families.
Project description:ImportanceFood insecurity is a critical social determinant of health for older adults. Understanding national food insecurity trends among families with older adults has important policy implications.ObjectiveTo compare food insecurity trends among US families with an older adult from 1999 to 2003 and 2015 to 2019 and further stratify the analysis by race and ethnicity, socioeconomic status markers, and enrollment in the federal Supplemental Nutrition Assistance Program (SNAP).Design, setting, and participantsIn this cohort study using biennial data from the nationally representative Panel Study of Income Dynamics, balanced panels of families with at least 1 older adult (≥60 years) who participated from 1999 to 2003 (n = 1311) and 2015 to 2019 (n = 2268) were created. Analysis was completed in 2023.Main outcomeFood insecurity was assessed using the US Household Food Security Survey Module. Within each 5-year period, we defined recurring food insecurity as 2 or more episodes of food insecurity and chronic food insecurity as 3 episodes of food insecurity.ResultsOverall, food insecurity among US families with older adults increased from 12.5% in 1999 to 2003 to 23.1% in 2015 to 2019. Rates of recurring food insecurity more than doubled (5.6% to 12.6%), whereas rates of chronic food insecurity more than tripled (2.0% to 6.3%). Across both time periods, higher rates of food insecurity persisted among Black and Hispanic families, with lower socioeconomic status, and participating in SNAP.Conclusions and relevanceThese results highlight how rates of recurring and chronic food insecurity among families with older adults rose substantially over the past 20 years. Monitoring national trends in food insecurity among older adults has direct programmatic and policy implications.
Project description:The obesity epidemic continues to challenge global health, driven by multifaceted environmental and biological factors. Here, we investigate the impact of food insecurity, characterized by unpredictable food access, on body weight, food intake, and body composition in mice. Male and female C57BL/6J mice were subjected to a combination of intermittent fasting and 5% calorie restriction to resemble food insecurity situations. Our results reveal that this novel food insecurity model promotes fat accumulation and decreases lean mass in both sexes on a standard chow diet. While food insecurity did not exacerbate fat gain in male mice fed a high-fat diet, it further reduced lean mass. RNA sequencing of epididymal white adipose tissue from food-insecure male mice identified upregulated lipid metabolism genes and downregulated immune response genes, suggesting adipocyte expansion and potential immunity dysfunction. These results challenge the traditional view that obesity is solely driven by positive energy balance. Instead, our findings highlight the role of food insecurity in promoting metabolic adaptations favouring fat storage. Our data provide biological mechanisms that may explain the dramatic rise in obesity, underscoring the importance of socio-economic factors, beyond diet composition and energy balance, in understanding the complex etiology of obesity.
Project description:BackgroundHigh food insecurity has been demonstrated in rural American Indian households, but little is known about American Indian families in urban settings or the association of food insecurity with diet for these families. The purpose of this study was to examine the prevalence of food insecurity in American Indian households by urban-rural status, correlates of food insecurity in these households, and the relationship between food insecurity and diet in these households.MethodsDyads consisting of an adult caregiver and a child (2-5 years old) from the same household in five urban and rural American Indian communities were included. Demographic information was collected, and food insecurity was assessed using two validated items from the USDA Household Food Security Survey. Factors associated with food insecurity were examined using logistic regression. Child and adult diets were assessed using food screeners. Coping strategies were assessed through focus group discussions. These cross-sectional baseline data were collected from 2/2013 through 4/2015 for the Healthy Children, Strong Families 2 randomized controlled trial of a healthy lifestyles intervention for American Indian families.ResultsA high prevalence of food insecurity was determined (61%) and was associated with American Indian ethnicity, lower educational level, single adult households, WIC participation, and urban settings (p = 0.05). Food insecure adults had significantly lower intake of vegetables (p < 0.05) and higher intakes of fruit juice (<0.001), other sugar-sweetened beverages (p < 0.05), and fried potatoes (p < 0.001) than food secure adults. Food insecure children had significantly higher intakes of fried potatoes (p < 0.05), soda (p = 0.01), and sports drinks (p < 0.05). Focus group participants indicated different strategies were used by urban and rural households to address food insecurity.ConclusionsThe prevalence of food insecurity in American Indian households in our sample is extremely high, and geographic designation may be an important contributing factor. Moreover, food insecurity had a significant negative influence on dietary intake for families. Understanding strategies employed by households may help inform future interventions to address food insecurity.Trial registration( NCT01776255 ). Registered: January 16, 2013.

Project description:BackgroundPediatric food allergy is associated with excess familial food costs compared to families without allergy. Since the start of the COVID-19 pandemic, food prices have increased substantially.ObjectiveTo understand the temporal pattern of food insecurity amongst Canadian families with food allergy from the year prior to the pandemic, through May 2022.MethodsUsing data collected electronically from families reporting food allergy using a validated food security questionnaire, we estimated food insecurity, including categories of food insecurity (marginal, moderate, secure) in the year prior to the pandemic (2019; Wave 1), and the first (2020; Wave 2) and second years of the pandemic (2022; Wave 3).ResultsParticipants in all waves were commonly in 2 + adult, 2 child households. Less than half of participants (Waves 1-3: 45.7%, 31.0%, and 22.9%, respectively) reported household incomes below the median Canadian. Common allergies were milk, eggs, peanuts and tree nuts. In Wave 1, 22.9% of families reported food insecurity; corresponding numbers at Waves 2 and 3 were 30.6% and 74.4%, respectively, representing an overall increase of 225.6%, including notable increases in severe food insecurity.ConclusionCanadian families with pediatric food allergy report higher rates of food insecurity compared to the general Canadian population, especially during the pandemic.
Project description:ObjectiveThe objective was to examine risk and protective factors associated with pre- to early-pandemic changes in risk of household food insecurity (FI).DesignWe re-enrolled families from two statewide studies (2017-2020) in an observational cohort (May-August 2020). Caregivers reported on risk of household FI, demographics, pandemic-related hardships, and participation in safety net programs (e.g. CARES stimulus payment, school meals).SettingMaryland, United States.ParticipantsEconomically, geographically, and racially/ethnically diverse families with preschool to adolescent-age children. Eligibility included reported receipt or expected receipt of the CARES stimulus payment or a pandemic-related economic hardship (n=496).ResultsPrevalence of risk of FI was unchanged (pre-pandemic: 22%, early-pandemic: 25%, p=0.27). Risk of early-pandemic FI was elevated for non-Hispanic Black (aRR=2.1 [95% CI 1.1, 4.0]) and Other families (aRR=2.6 [1.3, 5.4]) and families earning ≤300% federal poverty level. Among pre-pandemic food secure families, decreased income, job loss, and reduced hours were associated with increased early-pandemic FI risk (aRR=2.1 [1.2, 3.6] to 2.5 [1.5, 4.1]); CARES stimulus payment (aRR=0.5 [0.3, 0.9]) and continued school meal participation (aRR=0.2 [0.1, 0.9]) were associated with decreased risk. Among families at risk of FI pre-pandemic, safety net program participation was not associated with early-pandemic FI risk.ConclusionsThe CARES stimulus payment and continued school meal participation protected pre-pandemic food secure families from early-pandemic FI risk but did not protect families who were at risk of FI pre-pandemic. Mitigating pre-pandemic FI risk and providing stimulus payments and school meals may support children's health and reduce disparities in response to pandemics.
Project description:Although the high rate of food insecurity among people with disabilities and their households has emerged as an important concern in public health and nutrition policy, the available data on these issues are still too limited to fully understand this phenomenon. This study aimed to compare the prevalence of food insecurity between households with and without persons with disabilities and to explore which sociodemographic and disability characteristics are associated with household food insecurity among households with members with disabilities. The data of 2690 households with and without members with disabilities from the 2013 Korea National Health and Nutrition Examination Survey were analyzed. Household food insecurity was more prevalent among households including persons with disabilities than among those without such members. The likelihood of experiencing food insecurity was especially high in households having a female head with a disability (odds ratio (OR) = 1.98); working-age adults with disabilities (OR = 1.70); members with disabilities who were not economically active (OR = 1.53); and members with mental disabilities (OR = 2.81), disabilities involving internal organs (OR = 4.38), or severe (grades 1-3) disabilities (OR = 1.73). The findings indicate that the disability status and sociodemographic characteristics of disabled family members are closely associated with household food security status.
Project description:Optimal nutrition during infancy is critical given its influence on lifelong health and wellbeing. Two novel methods of infant complementary feeding, commercial baby food pouch use and baby-led weaning (BLW), are becoming increasingly popular worldwide. Household food insecurity may influence complementary feeding practices adopted by families, but no studies have investigated the use of BLW and baby food pouches in families experiencing food insecurity. The First Foods New Zealand study was a multicentre, observational study in infants 7.0-9.9 months of age. Households (n = 604) were classified into one of three categories of food insecurity (severely food insecure, moderately food insecure, and food secure). The use of complementary feeding practices was assessed via a self-administered questionnaire, both at the current age (mean 8.4 months) and retrospectively at 6 months. Mothers experiencing severe food insecurity had 5.70 times the odds of currently using commercial baby food pouches frequently (≥5 times/week) compared to food secure mothers (95% CI [1.54, 21.01]), reporting that pouches were 'easy to use' (89%) and made it 'easy to get fruits and vegetables in' (64%). In contrast, no evidence of a difference in the prevalence of current BLW was observed among mothers experiencing moderate food insecurity (adjusted OR; 1.28, 95% CI [0.73, 2.24]) or severe food insecurity (adjusted OR; 1.03, 95% CI [0.44, 2.43]) compared to food secure mothers. The high prevalence of frequent commercial baby food pouch use in food insecure households underscores the need for research to determine whether frequent pouch use impacts infant health.
Project description:BackgroundThe burden of food insecurity remains a public health challenge even in high income countries, such as Australia, and especially among culturally and linguistically diverse (CALD) communities. While research has been undertaken among several migrant communities in Australia, there is a knowledge gap about food security within some ethnic minorities such as migrants from the Middle East and North Africa (MENA). This study aims to determine the prevalence and correlates of food insecurity among Libyan migrant families in Australia.MethodsA cross-sectional design utilising an online survey and convenience sampling was used to recruit 271 participants, each representing a family, who had migrated from Libya to Australia. Food security was measured using the single-item measure taken from the Australian Health Survey (AHS) and the 18-item measure from the United States Department of Agriculture Household Food Security Survey Module (USDA HFSSM). Multivariable logistic regression was used to identify independent correlates associated with food insecurity.ResultsUsing the single-item measure, the prevalence of food insecurity was 13.7% whereas when the 18-item questionnaire was used, more than three out of five families (72.3%) reported being food insecure. In the multivariable logistic regression analysis for the single-item measure, those living alone or with others reported higher odds of being food insecure (AOR = 2.55, 95% CI 1.05, 6.21) compared to those living with their spouse, whereas higher annual income (≥AUD 40,000) was associated with lower odds of food insecurity (AOR = 0.30, 95% CI 0.11, 0.84). Higher annual income was also associated with lower odds of food insecurity (AOR = 0.49, 95% CI 0.25, 0.94) on the 18-item measure. On both single and 18-item measures, larger family size (AOR = 1.27, 95% CI 1.07, 1.49 and AOR = 1.21, 95% CI 1.01, 1.47 respectively) was associated with increased odds of food insecurity.ConclusionThis study provides evidence that food insecurity amongst Libyan migrants in Australia is a widespread problem and is associated with a number of sociodemographic and socio-economic factors. The findings of this study serve to contribute to the depth and breadth of food security research among vulnerable communities, in this instance Libyan migrant families.
