Food insecurity is associated with suboptimal sleep quality, but not sleep duration, among low-income Head Start children of pre-school age

Food and housing insecurity, COVID-19 pandemic effects on health-related activities, and care plans for children with obesity

OBJECTIVE

To understand the association between food insecurity (FI) and housing insecurity (HI) risk, the effects of the COVID-19 pandemic on health-related activities among children with overweight or obesity, and caregivers' and clinicians' challenges and priorities related to pediatric weight management.

METHODS

We conducted surveys with caregivers of children with overweight and obesity and pediatric clinicians at two academic medical centers in the Greater Boston area. We used multivariable logistic regression models to examine associations between FI and HI risk and the effects of the COVID-19 pandemic on health-related activities and descriptive statistics to summarize caregivers' and clinicians' challenges and priorities related to pediatric weight management.

RESULTS

We analyzed data from surveys with 344 caregivers and 100 pediatric clinicians. Overall, 37% of caregivers endorsed both FI+HI, 18% FI alone, 10% HI alone, and 35% neither FI/HI. In the adjusted logistic regression models, combined FI+HI (reference: neither FI/HI) was significantly associated with higher odds of sleeping less (aOR 2.96 [95% confidence interval (CI): 1.46, 6.01]) and higher odds of spending less time outside (aOR 2.10 [95% CI: 1.06, 4.16]). Top priorities for pediatric weight management identified by both caregivers and clinicians were related to physical activity and availability of outdoor spaces.

CONCLUSIONS

Endorsement of both FI+HI was associated with children getting less sleep and spending less time outside during the COVID-19 pandemic. Future innovations in care plans for children with overweight and obesity should be adapted to a family's social context and should incorporate caregivers' and clinicians' challenges and priorities.

Translational science approaches for food insecurity research

Food insecurity is a pervasive problem that impacts health and well-being across the lifespan. The human research linking food insecurity to poor metabolic and behavioral health outcomes is inherently correlational and suffers from a high degree of variability both between households and even within the same household over time. Further, food insecurity is impacted by societal and political factors that are largely out of the control of individuals, which narrows the range of intervention strategies. Animal models of food insecurity are being developed to address some of the barriers to mechanistic research. However, animal models are limited in their ability to consider some of the more complex societal elements of the human condition. We believe that understanding the role that food insecurity plays in ingestive behavior and chronic disease requires a truly translational approach, and that understanding the health impacts of this complex social phenomenon requires understanding both its psychological and physiological dimensions. This brief review will outline some key features of food insecurity, highlighting those that are amenable to investigation with controlled animal models and identifying areas where integrating animal and human studies can improve our understanding of the psychological burden and health impacts of food insecurity. In the interest of brevity, this review will largely focus on food insecurity in the United States, as the factors that contribute to food insecurity vary considerably across the globe.

Food insecurity and the risk of sleep disorders in people living with HIV/AIDS as a neglected health concern: A national survey in Iran

Food insecurity (FI) and sleep problems are major modifiable health issues among people living with HIV/AIDS (PLWH), and there is limited knowledge about their prevalence among this underrepresented population. Our study aimed to assess the relationship between FI and sleep problems as important environmental factors affecting PLWH in Iran. The national survey was conducted on 1185 confirmed HIV-positive patients who attended consulting centers in 15 geographically diverse provinces in Iran, during 2021-2022. Standard questionnaires were used to measure FI and sleep problems (Insomnia, Obstructive Sleep apnea (OSA), Excessive Daytime Sleepiness (EDS), and Poor sleep quality), and a logistic regression model was used to assess the association between FI and the odds of experiencing sleep problems. About 764 (The prevalence of FI = 64.47 %) of the participants had insecure status, with a mean score of 11.73 (SE = 0.34). Those with FI had a higher prevalence of insomnia, EDS, and poor sleep quality (54.84 %, 31.79 %, and 55.17 %, respectively) compared to those without FI (30.69 %, 17.03 %, and 40.42 %, respectively). FI increased the odds of being at risk for Insomnia (OR = 2.39, 95 % CI: 1.81-3.15), EDS (OR = 1.44, 95 % CI: 1.04-2.01), and poor sleep quality (OR = 1.79, 95 % CI: 1.29-2.48) in the multiple regression model. The results highlight the strong association between FI and a broad range of sleep problems in PLWH. Considering the impact of FI and impaired sleep health on PLWH, more attention is needed for at-risk groups for screening and intervention purposes.

Examining ADHD and Cognitive Disengagement Syndrome Symptoms in Relation to Food Insecurity in Early Adolescents

Approximately 13.8 million U.S. households face food insecurity, which severely affects child development, with more than half of these households including children. Research links food insecurity to cognitive deficits and mental health challenges, highlighting the need for thorough understanding and intervention. Although existing studies have explored the association between food insecurity and internalizing symptomatology, less research has examined food insecurity in relation to attention-deficit/hyperactivity disorder (ADHD) symptoms. Further, no studies have explored the connection between food insecurity and cognitive disengagement syndrome (CDS) symptoms, closely related to ADHD symptoms. Despite extant research linking CDS to environmental factors, empirical attention to its potential association with food insecurity is notably lacking. Additionally, adolescents, almost twice as likely as younger children to experience household food insecurity, are likely more aware and respond differently to challenges during this developmental period. Accordingly, this study investigated the unique associations of parent-, teacher-, and youth self-reported ADHD dimensions and CDS symptoms in relation to parent-reported food insecurity in early adolescents (N = 136, ages 10-12). Controlling for age, sex, race, and medication use, no informant's ratings of ADHD symptom dimensions were uniquely related to food insecurity. In contrast, higher parent-, teacher-, and youth self-reported CDS symptoms were uniquely associated with greater food insecurity. This finding was robust to additional control of family income for teacher- and youth self-reported CDS symptoms. These findings highlight the complex link between food insecurity and mental health, suggest a connection with CDS symptoms, and stress the need to address food insecurity as a public health priority, especially in early adolescence.

Lifestyle Clusters of Diet Quality, Sleep, and Screen Time and Associations with Weight Status in Children from Madrid City: ENPIMAD Study

BACKGROUND

Childhood overweight and obesity is a global concern and has increased in Spain over the last decades. Combinations of lifestyle behaviors (i.e., diet, sleep, and sedentarism) are highly related to weight status. Therefore, this study aimed to identify lifestyle patterns among children from Madrid City, and analyze associations with the prevalence of overweight, obesity, and abdominal obesity, considering socio-economic factors.

METHODS

A cross-sectional analysis was conducted on 4545 children from the ENPIMAD study with data on diet, sleep, anthropometric, and socio-economic variables. K-means cluster analysis was used to identify lifestyle clusters, and logistic regressions were used to examine the associations between socio-economic indicators and cluster membership, and between clusters and weight status.

RESULTS

Findings show three lifestyle clusters (healthy, mixed, and unhealthy), with boys and older children more represented in the unhealthy cluster. Food insecurity and low socio-economic status were associated with unhealthier clusters in boys and girls. Children in unhealthier clusters were more likely to have obesity and abdominal obesity. However, these associations disappeared in girls after controlling for food insecurity.

CONCLUSION

These results provide insight into the combination of behaviors and socio-economic factors associated with childhood obesity that may aid in the design of future interventions.

Food Insecurity and Sleep-Related Problems in Adolescents: Findings from the EHDLA Study

PURPOSE

The current research aimed to investigate the connection between food insecurity and sleep issues among Spanish adolescents aged from 12 to 17 years from the Valle de Ricote (Region of Murcia, Spain).

METHODS

Data from the Eating Healthy and Daily Life Activities Study, which included a sample of 836 adolescents (55.3% girls), were analyzed. Food insecurity was evaluated using the Child Food Security Survey Module in Spanish (CFSSM-S), while sleep-related problems were evaluated using the Bedtime problems, Excessive daytime sleepiness, Awakenings during the night, Regularity and duration of sleep, and Sleep-disordered breathing (BEARS) sleep screening tool. Generalized linear models were employed to explore the association between food insecurity and sleep-related issues.

RESULTS

Compared with their counterparts with food security, adolescents with food insecurity had greater probabilities of bedtime problems (24.1%, 95% confidence interval (CI) 16.9% to 33.0%, p = 0.003), excessive daytime sleepiness (36.4%, 95% CI 27.5% to 46.3%, p < 0.001), awakenings during the night (16.7%, 95% CI 10.8% to 25.1%, p = 0.004), and any sleep-related problems (68.1%, 95% CI 57.5% to 77.1%, p < 0.001).

CONCLUSIONS

This study suggests that food insecurity is related to greater sleep-related problems among adolescents. Implementing strategies to mitigate food insecurity may contribute to improved sleep health among adolescents, highlighting the importance of integrated public health interventions.

Sleep Duration Is Associated with Household Food Insecurity and Sugar-Sweetened Beverage Intake Among Women, Infants and Children Participating Children Ages 0-5

PURPOSE

To determine associations between child and household characteristics and sleep duration among low-income children in Los Angeles County.

DESIGN

Cross-sectional study.

SETTING

Survey data collected in 2017 and 2020 in Los Angeles County, California.

SAMPLE

Special Supplemental Nutrition Program for Women, Infants and Children (WIC) households with children ages 4-60 months.

MEASURES

Sleep duration for children 4-60 months old (less than recommended (LTR), recommended range, more than recommended (MTR)), household food insecurity (HFI), sociodemographics, and daily servings of sugar-sweetened beverages (SSB).

ANALYSIS

Multinomial logistic regression, stratified by child age, was used to calculate odds ratios (OR) and 95% confidence intervals (CI) for associations between household/child characteristics and LTR or MTR sleep compared to recommended duration among WIC participating children 4-60 months old.

RESULTS

The final sample included 3512 children ages 4-23 months and 6035 children ages 24-60 months. In the study population, 32% (3-5 years old) to 44% (4-11months) of children under 5 did not meet the recommended hours of sleep per night. HFI was associated with higher odds of LTR (OR 1.27, CI 1.12-1.45) and MTR (OR 1.46, CI 1.15-1.87) sleep among 24-60 month-old children. Each additional daily SSB serving was associated with higher odds of LTR sleep (4-23 months: OR 1.10, CI 1.02-1.19; 24-59 months: OR 1.12, CI 1.08-1.17).

CONCLUSIONS

HFI and SSB intake are associated with not getting the recommended amount of sleep among low-income WIC participating children. Nutrition assistance program participants may benefit from receiving information about recommended sleep duration for young children and how to establish sleep routines to optimize sleep duration.

Food insecurity and its impact on substance use and suicidal behaviours among school-going adolescents in Africa: evidence from the Global School-Based Student Health Survey

The study sought to assess the prevalence and factors associated with Food Insecurity (FI) and further quantify its impact on substance use and suicidal behaviours (ideation, planning, and repeated attempted suicide) among school-going adolescents in Africa. The study involved a secondary analysis of cross-sectional data from the Global School-Based Student Health Survey (GSHS) conducted in Africa. Substance use and suicidal behaviours were the main outcomes. We employed the Double Selection Least Absolute Shrinkage and Selection Operator Poisson regression (DSLASSOPM) model to assess risk factors associated with FI and further employed Coarsened Exact Matching involving DSLASSOPM to assess the influence of FI on the study outcomes. Meta-analysis was conducted to obtain between-country heterogeneity in the prevalence of FI and the prevalence ratio of substance use and suicidal behaviours. The study involved 34,912 school-going adolescents. The pooled 30-day prevalence estimate of FI was 11.1% (95% CI  9.1-18.6), ranging from 6.7% (95% CI 5.0-8.3) in Tanzania to 18.4% (95% CI 14.4-22.4) in Benin. The most common associated factors included the experience of insomnia and the number of times injured. The pooled prevalence ratio of substance use, suicidal ideation, suicidal planning, and repeated attempted suicide among adolescents experiencing food insecurity were 1.92(95% CI 1.69-2.16), 1.56(95% CI 1.46-1.66), 1.50 (95% CI 1.41-1.58), and 1.90 (95% CI 1.73-2.07) respectively. A considerable heterogeneity between the sub-regions prevalence ratio for suicidal ideation and planning was also observed (I2 = 0, p value > 0.05). The study observed a high prevalence of food insecurity in West Africa with negligible heterogeneity between the countries. A significant positive association between FI and the study outcomes (substance use and suicidal behaviours) was observed. The study recommends country-specific social and school-based health interventions to screen risk factors associated with food insecurity for early identification. Measures to achieve Sustainable Development Goal 2 (Zero Hunger) by 2030 are key in these African countries and is likely to yield demographic dividends through improvement in mental health among school-going adolescents.

Associations between food insecurity and Sleep Duration, Quality, and Disturbance among older adults from six low- and middle-income countries

OBJECTIVES

Although food insecurity has been associated with poor sleep outcomes in young and middle-aged adults, few studies have examined this relationship in older adults. This study aimed to examine the relationship between food insecurity and sleep duration, quality, and disturbance among older adults in six low-income countries (LMICs).

DESIGN AND SETTING

We analyzed nationally representative cross-sectional data from 33,460 adults (≥50 years) from the Study on global AGEing and adult health (SAGE).

MEASUREMENTS

Food insecurity (FI) was assessed using two questions regarding the frequency of eating less and hunger caused by a lack of food. Sleep outcomes included self-reported sleep duration, sleep quality, and sleep disturbances (difficulty falling asleep, frequent sleep interruptions, and early awakening) assessed based on self-reports over two nights. Multivariable logistic regression was used to assess country-specific relationships between food insecurity and sleep outcomes, and random-effects models were used to estimate pooled associations.

RESULTS

The prevalence of FI among older adults in the overall population was 16.2%. In pooled analyses, FI was significantly associated with long sleep duration ≥ 9 h (OR=1.58, 95% CI: 1.30 to 1.93; P=0.001). There were also significant pooled associations between FI and poor sleep quality (OR=1.34, 95% CI: 1.14 to 1.56; P < 0.001) and sleep disturbances (OR=1.44, 95% CI: 1.08 to 1.91; P = 0.014).

CONCLUSIONS

In conclusion, the current study found that FI is adversely associated with sleep duration, quality and disturbances in older adults, with some heterogeneity by country. The findings suggest food policies and intervention programs are needed for vulnerable households.

Food Intake and Sleep Disorders in Children and Adolescents with Obesity

Over the last few decades, numerous scientific studies have investigated the possible association between sleep duration and adiposity during childhood, since it has been reported that sleep deprivation causes a related increase in caloric intake. Even though the underlying pathogenetic mechanisms are still under study and not completely known, the effect of dietetic habits and nutrient intake on sleep quality and patterns has been reported. The aim of this study is to explore the intricate interplay between food intake/diet patterns and pediatric sleep disturbances in children and adolescents with obesity, emphasizing the importance of not underestimating this aspect in the prevention and treatment of this complex disease. Recent evidence supports a high correlation between specific diet patterns and foods with sleep disturbances in children at all ages. Diets rich in fiber, fruit, vegetables, and anti-inflammatory nutrients and low in saturated fats seem to promote better sleep quality. Sleep disturbances are, in turn, risk factors for the development of obesity. Therefore, food strategies should be applied to counteract this harmful process. Unraveling the complex links between dietary habits, sleep patterns, and obesity is essential for developing effective strategies to combat this critical public health issue.

Diet and Food and Nutrition Insecurity and Cardiometabolic Disease

Poor nutrition is the leading cause of poor health, health care spending, and lost productivity in the United States and globally, which acts through cardiometabolic diseases as precursors to cardiovascular disease, cancer, and other conditions. There is great interest in how the social determinants of health (the conditions in which people are born, live, work, develop, and age) impact cardiometabolic disease. Food insecurity is an example of a powerful social determinant of health that impacts health outcomes. Nutrition insecurity, a distinct but related concept to food insecurity, is a direct determinant of health. In this article, we provide an overview of how diet in early life relates to cardiometabolic disease and then continue to focus on the concepts of food insecurity and nutrition insecurity. In the discussions herein we make important distinctions between the concepts of food insecurity and nutrition insecurity and provide a review of their concepts, histories, measurement and assessment devices, trends and prevalence, and links to health and health disparities. The discussions here set the stage for future research and practice to directly address the negative consequences of food and nutrition insecurity.

Household food insufficiency and flourishing in a nationally representative sample of young children in the U.S

PURPOSE

This study examined the association between household food insufficiency and flourishing among young children (6 months-5 years) in the U.S. and assessed whether sleep adequacy modifies this association.

METHODS

We used data from the 2018-2020 National Surveys of Children's Health. Adjusted prevalence differences and 95% confidence intervals (CI) for the association between household food insufficiency and flourishing were modeled using average marginal predictions from logistic regression models. Sleep adequacy was assessed as an effect measure modifier on the additive scale.

RESULTS

Evidence supports additive scale effect measure modification of the food insufficiency-flourishing association by sleep adequacy (Likelihood Ratio Test statistic = 12.4, degrees of freedom = 2, P < .05). Adjusted for potential confounders, the prevalence of flourishing was 13.2 percentage points lower (95% CI: -22.6, -3.7) for children in households with insufficient food and inadequate sleep compared to those with sufficient food and adequate sleep.

CONCLUSIONS

Our findings suggest that having enough food and enough sleep are associated with greater wellbeing. These modifiable factors should be targeted by public health interventions to facilitate flourishing among young children in the U.S.

Food insecurity is associated with the sleep quality and quantity in adults: a systematic review and meta-analysis

OBJECTIVE

We evaluated associations between food insecurity (FI) and the quality and quantity of sleep in adults (≥18 years).

DESIGN

The current study represented a systematic review and meta-analysis of observational studies.

SETTING

Databases of PubMed, Scopus, Embase and Web of Science were searched from inception until 6 June 2022. Meta-analyses were conducted using random-effects models, and effect sizes were reported as OR and 95 % CI.

PARTICIPANTS

Data from ten eligible observational studies, including 83 764 participants, were included.

RESULTS

FI was associated with an increased risk of poor sleep quality (OR = 1·45; 95 % CI (1·24, 1·70), I2 = 95, P < 0·001, n 7). Besides, subgroup analysis showed increased risk of poor sleep quality corresponding to the severity of FI across mild (OR = 1·31; 95 % CI (1·16, 1·48), I2 = 0 %, P < 0·001, n 5), moderate (OR = 1·49; 95 % CI (1·32, 1·68), I2 = 0 %, P < 0·001, n 5) and severe (OR = 1·89; 95 % CI (1·63, 2·20), I2 = 0 %, P < 0·001, n 5) levels. Similarly, subgroup analysis by sleep problems showed that FI was associated with an increased the risk of trouble falling asleep (OR = 1·39; 95 % CI (1·05, 1·83), I2 = 91 %, P = 0·002, n 3) and trouble staying asleep (OR = 1·91; 95 % CI (1·37, 2·67), I2 = 89 %, P < 0·001, n 3). Moreover, FI was associated with the odds of shorter (OR = 1·14; 95 % CI (1·07, 1·21), I2 = 0 %, P < 0·001, n 4) and longer sleep duration (OR = 1·14; 95 % CI (1·03, 1·26), I2 = 0 %, P = 0·010, n 4).

CONCLUSIONS

Collective evidence supports that FI is associated with poor sleep quality and quantity in adults. Preventative and management strategies that address FI may provide health benefits beyond improving nutritional status per se.

Sleep, nutritional status and eating behavior in children: a review study

OBJECTIVE

To review the current literature on the relationship between sleep, nutritional status and eating behavior, as well as mechanisms associated with these elements in children.

DATA SOURCE

The literature research was conducted in the PubMed, LILACS and Scopus databases, using the following terms: "Child"; "Nutritional status"; "Sleep"; "Physical activity OR Physical activities OR Exercise". The articles included were those that met the research objective. Review articles, letters to authors, or guidelines were excluded.

DATA SYNTHESIS

402 articles were initially found in the literature search. After careful analyses of the title and abstract, and application of inclusion criteria, only 24 studies were included in the present review. Most studies (n=13) suggest that short sleep duration (<9-10 hours/night) is associated with overweight/obesity in children. Only three studies did not show associations between overweight/obesity and sleep variables. Short sleep duration is also associated with poor food quality, higher intake of soft drinks and stimulant beverages before bedtime, as well as micronutrient deficiency.

CONCLUSIONS

Sleep duration is related to overweight and obesity development in infants. Changes in dietary pattern are also related to sleep debt, being one of the mechanisms that contribute to excessive weight gain. It is necessary that health professionals understand the importance of sleep quality in the nutritional status maintenance in children.

Associations Between Diaper Need and Child Sleep in Under-resourced Families

OBJECTIVE

Sleep is critical for child health, but factors related to poverty create barriers to the achievement of healthful sleep. In this study, we examined the associations of insufficient diaper supply, a measure of material hardship, with child sleep.

METHODS

This cross-sectional study included 129 parents of very young children. Each participant responded to an online material hardship assessment and the Brief Infant Sleep Questionnaire-Revised. Multiple linear regression was used to analyze the relationship between diaper need and sleep.

RESULTS

Controlling for family and socioeconomic variables, diaper need was associated with disrupted, shorter sleep periods (β = -11.95, p < 0.001) and lower total sleep scores (β = -6.49, p = 0.004). High diaper need was associated with parent perception of poor sleep (β = -7.28, p = 0.017).

CONCLUSION

The findings suggest that an inadequate supply of diapers adversely affects children's sleep. Further research should evaluate how screening and connecting families to resources may improve pediatric sleep.

The Mediating Effect of Sleep Duration on the Association between Food Insecurity and Childhood Obesity

Background: Childhood obesity has increased globally during the past four decades. Food insecurity could heighten the risk of obesity. However, little is known about the underlying mechanism. This study aims to investigate the mediating role of sleep duration in the association between food insecurity and childhood obesity and whether there are differences by age, sex, and race/ethnicity. Method: Data from the National Survey of Children's Health for the years 2016-2020 were used, including children 10-17 years of age. We employed causal mediation analysis within a counterfactual framework to decompose the total effect of food insecurity into natural direct and indirect effects and estimate the proportion mediated. Result: The prevalence of obesity was 15.8% in our study sample. Children with food insecurity had 78% higher odds [odds ratio (OR) = 1.78, 95% confidence interval (CI): 1.70-1.86] of having obesity compared with children who were food secure. Overall, only 6.13% of this association was mediated by sleep duration. The association between food insecurity and obesity was stronger in females (OR = 1.96, 95% CI: 1.84-2.10) than males (OR = 1.66, 95% CI: 1.56-1.75), but the proportion mediated by sleep duration was larger in males (7.13%) than females (5.22%). Evidence of mediation was more pronounced in children 10-11 years of age and non-Hispanic Asian children (proportion mediated = 14.85% and 11.21%, respectively). Conclusion: Food insecurity is associated with an increased prevalence of obesity among children. Although a small proportion of this association is mediated by sleep duration, these results suggest that sleep should be considered when assessing the link between food insecurity and childhood obesity.

Sono, estado nutricional e hábitos alimentares em crianças: um estudo de revisão

RESUMO Objetivo: Fazer uma revisão da literatura sobre a relação entre sono, estado nutricional e padrão alimentar, bem como mecanismos associados, na população infantil. Fontes de dados: Foram realizadas buscas bibliográficas nas bases PubMed, LILACS e Scopus, usando os seguintes descritores: “Child”; “Nutritional status”; “Sleep”; “Physical activity OR Physical activities OR Exercise”. Os artigos que atenderam ao objetivo da pesquisa foram incluídos. Excluíram-se estudos de revisão, cartas para autores ou diretrizes. Síntese dos dados: Inicialmente, 402 artigos foram encontrados na pesquisa. Após análise dos títulos e abstracts e a aplicação dos critérios de exclusão, 24 estudos foram selecionados para a revisão. A maioria dos estudos (n=13) sugere que sono de curta duração (<9-10 horas/noite) está associado com sobrepeso/obesidade na população infantil. Apenas três artigos não reportaram associações entre variáveis do sono e estado nutricional. Curta duração do sono também foi associada a hábitos alimentares ruins, maior consumo de refrigerantes e bebidas estimulantes antes de deitar, bem como deficiência de micronutrientes. Conclusões: A duração do sono tem relação com sobrepeso e obesidade na população infantil. Alterações no padrão alimentar também têm relação com débito de sono, sendo um dos mecanismos que contribuem para o ganho de peso excessivo. É necessário que os profissionais de saúde tomem conhecimento da importância da qualidade do sono para a manutenção do estado nutricional em crianças.

Food insecurity is associated with higher food responsiveness in low-income children: The moderating role of parent stress and family functioning

BACKGROUND

Food insecurity (FI) may increase the odds for childhood obesity, yet little is known about the mechanism explaining this relationship. Parents experience greater psychosocial stress in the context of FI. In these environments, children from FI households may exhibit different appetitive behaviours.

OBJECTIVES

To examine associations between FI and appetitive behaviours in children (3-5 years) and to explore whether social, emotional and structural properties of the home environment moderate this relationship.

METHODS

In a low-income sample of 504 parent-child dyads, parents completed the household food security module and the Children's Eating Behavior Questionnaire. A subsample (n = 361) self-reported perceived stress, depressive symptoms, household chaos and family functioning. Children were categorized as food secure, household FI and child FI.

RESULTS

Food responsiveness (LSmeans ± SE; child FI: 2.56 ± 0.13; food secure: 2.31 ± 0.10, p < 0.05) and emotional overeating (LSmeans ± SE; child FI: 1.69 ± 0.10; food secure: 1.48 ± 0.08, p < 0.05) were higher among children in the child FI group compared to the food secure group. Child FI was only associated with higher food responsiveness among children of parents reporting high levels of perceived stress (p = 0.04) and low levels of family functioning (p = 0.01). There were no differences in food responsiveness by food security status at mean or low levels of perceived stress or at mean or high levels of family functioning (p > 0.05).

CONCLUSIONS

Child FI may contribute to obesity risk through differences in appetitive behaviours. For low-income families, stress management and improving family dynamics may be important factors for interventions designed to improve children's appetitive behaviours.

How Food Insecurity and Financial Difficulty Relate to Emotional Well-Being and Social Functioning

OBJECTIVES

Medically uninsured individuals living in poverty experience poor health and face social barriers that negatively affect their health. The purpose of this study was to examine the association between social barriers, particularly healthy food availability and financial difficulty, and well-being among uninsured free clinic patients in the United States.

METHODS

Data were collected using a self-administered paper survey at a free clinic from adult patients who spoke and read English or Spanish (N = 666) from January to April 2019.

RESULTS

Better neighborhood healthy food availability is associated with better self-reported general health. Food security is related to better emotional well-being and social functioning. Having difficulty paying rent or a mortgage is linked to worse emotional well-being and social functioning.

CONCLUSIONS

Providing health education programs may not be sufficient to promote healthy eating among underserved populations because of the social barriers that they experience, such as food insecurity and financial difficulty. Future research could be performed to determine how these social factors influence those of different social and cultural backgrounds than the participants in this study.

COVID-19 and behaviors in children with autism spectrum disorder: Disparities by income and food security status

BACKGROUND

Research on the impact of the COVID-19 pandemic on behaviors of children with autism spectrum disorder (ASD) is lacking.

AIMS

This study investigates the relationship between COVID-19 and behaviors of children with ASD living in the United States.

METHODS AND PROCEDURES

Parents and caregivers (n = 200) across the United States, as proxies for children 2-17 years of age with ASD, participated in an online survey querying changes in overall behavior and 15 specific behaviors during the COVID-19 pandemic. Logistic regression was used to assess the association of a moderate-to-large impact on the child's overall behavior with household income level and food security status.

OUTCOMES AND RESULTS

A majority of respondents reported a moderate-to-large impact on the child's overall behavior (74 %) due to COVID-19. Several specific behaviors were also affected. Stratifying by income level and food security status revealed disparities in the impact on overall behavior and most specific behaviors. Compared to a household income ≥$100 K, an income <$50 K was associated with an increased risk of moderate-to-large impact on the child's overall behavior (odds ratio (OR): 4.07, 95 % CI: 1.60, 10.38). Food insecurity also significantly impacted this risk, even after adjusting for potential confounding factors (OR: 3.31, 95 % CI: 1.13, 9.66).

CONCLUSIONS AND IMPLICATIONS

Our findings show a large proportion of caregivers reporting moderate-to-large changes post-COVID-19 in the behaviors of U.S. children with ASD, particularly in families with low income and/or food insecurity. This study highlights the effects of existing disparities on children with ASD and their families during this unprecedented time.

The Relative Reinforcing Value of Cookies Is Higher Among Head Start Preschoolers With Obesity

The relative reinforcing value (RRV) of food measures how hard someone will work for a high-energy-dense (HED) food when an alternative reward is concurrently available. Higher RRV for HED food has been linked to obesity, yet this association has not been examined in low-income preschool-age children. Further, the development of individual differences in the RRV of food in early childhood is poorly understood. This cross-sectional study tested the hypothesis that the RRV of HED (cookies) to low-energy-dense (LED; fruit) food would be greater in children with obesity compared to children without obesity in a sample of 130 low-income 3- to 5-year-olds enrolled in Head Start classrooms in Central Pennsylvania. In addition, we examined individual differences in the RRV of food by child characteristics (i.e., age, sex, and reward sensitivity) and food security status. The RRV of food was measured on concurrent progressive-ratio schedules of reinforcement. RRV outcomes included the last schedule reached (breakpoint) for cookies (cookie Pmax) and fruit (fruit Pmax), the breakpoint for cookies in proportion to the total breakpoint for cookies and fruit combined (RRV cookie), and response rates (responses per minute). Parents completed the 18-item food security module to assess household food security status and the Behavioral Activation System scale to assess reward sensitivity. Pearson's correlations and mixed models assessed associations between continuous and discrete child characteristics with RRV outcomes, respectively. Two-way mixed effects interaction models examined age and sex as moderators of the association between RRV and Body Mass Index z-scores (BMIZ). Statistical significance was defined as p < 0.05. Children with obesity (17%) had a greater cookie Pmax [F (1, 121) = 4.95, p = 0.03], higher RRV cookie [F (1, 121) = 4.28, p = 0.04], and responded at a faster rate for cookies [F (1, 121) = 17.27, p < 0.001] compared to children without obesity. Children with higher cookie response rates had higher BMIZ (r = 0.26, p < 0.01); and RRV cookie was positively associated with BMIZ for older children (5-year-olds: t = 2.40, p = 0.02) and boys (t = 2.55, p = 0.01), but not younger children or girls. The RRV of food did not differ by household food security status. Low-income children with obesity showed greater motivation to work for cookies than fruit compared to their peers without obesity. The RRV of HED food may be an important contributor to increased weight status in boys and future research is needed to better understand developmental trajectories of the RRV of food across childhood.

Sleep, Food Insecurity, and Weight Status: Findings from the Family Life, Activity, Sun, Health, and Eating Study

Background: Shorter sleep duration and lower sleep quality have been previously associated with greater obesity risk among adult samples. Food insecurity has also been found to impact sleep patterns and obesity. Yet few studies have explored associations between sleep, food insecurity, and obesity in adolescent populations, who may have more irregular sleep patterns. Thus, the objectives of this study were to determine associations between measures of sleep, food insecurity, and weight status. Methods: Data were obtained from the Family Life, Activity, Sun, Health, and Eating (FLASHE) Study, an online cross-sectional study of parent and adolescent (12-17-year old) dyads. Participants were drawn from a Consumer Opinion Panel representative of the general population of the United States with respect to sex, education, income, age, household size, and region. First, multinomial logistic regression analyses were conducted to determine associations between sleep measures (adolescent-reported average nighttime sleep duration, having a regular bedtime, and having difficulty staying asleep), food insecurity (a validated two-item parent-reported measure), and weight status (being underweight, of healthy weight, overweight, and obese). Weight status was based upon adolescent BMI z-scores using Centers for Disease Control and Prevention growth charts using information from parent report of adolescent height and weight and adolescent-reported age and sex among adolescents (N = 1544). Conditional process models were also fitted to the data to determine whether food insecurity moderates the associations between sleep measures and weight status, and to determine whether the association between food insecurity and weight status is mediated by average sleep duration. Results: Compared to those with food security, a greater percentage of those with food insecurity reported having difficulties staying asleep and a longer average sleep duration. Multinomial logistic regression models demonstrated that having a regular bedtime was associated with lower odds of having obesity, having difficulties staying asleep was associated with greater odds of being underweight, and having food insecurity was associated with greater odds of being overweight. Conditional process models demonstrated that food insecurity did not moderate associations between sleep measures and weight status and that average nighttime sleep duration did not mediate the association between food insecurity and weight status. Conclusions: This is one of the first studies to examine associations between sleep, food insecurity, and weight status among adolescents. Results provide additional support for the need to uncover mechanisms for how sleep and food insecurity affect pediatric obesity using longitudinal data.

Tobacco use and sleep loss over worry among adolescents aged 12-15 years: A population-based study of 38 countries

BACKGROUND

Sleep loss is increasingly recognized as a key public health issue among adolescents. Tobacco use is one of the leading causes of preventable disease and death in the world. Yet, the association between tobacco use and sleep loss has been understudied in the adolescent population. This study aimed to examine this association utilizing nationally representative samples of adolescents.

METHODS

Cross-sectional data on 109 408 adolescents (12-15 years) from 38 countries were derived from the Global School-based Student Health Survey (GSHS). Weighted age- and sex-adjusted distribution of each sample characteristics was calculated. Multivariate logistic regression and meta-analyses were performed to assess the association of sleep loss over worry with any tobacco use, while controlling for important confounders, including age, gender, loneliness, physical attack victimization, parental knowledge/warmth, and perceived peer kindness/helpfulness.

RESULTS

The weighted age- and sex-adjusted prevalence of SLOW and use of any tobacco product was 6.4% and 7.4% respectively across 38 countries. The overall odds of sleep loss over worry were 1.89 times (95% confidence interval (CI) = 1.75, 2.03) greater among tobacco users than among non-users, with low level of between-country heterogeneity (I2  = 24.0%, P = 0.095). The odds of sleep loss over worry were 1.61 times (95% CI = 1.52, 1.71) greater among those reporting physical attack victimization than among non-victims, and 5.55 times (95% CI = 4.95, 6.21) greater among those reporting frequent than less frequent loneliness.

CONCLUSIONS

Tobacco use, physical attack victimization, and loneliness can be key indicators of SLOW, and may be included in the assessment and prevention of SLOW to generate a more comprehensive picture. Further studies are needed to determine if reducing tobacco use, loneliness, or physical attack victimization would make a meaningful impact on reducing SLOW.

The Relationship between Food Security Status and Sleep Disturbance among Adults: A Cross-Sectional Study in an Indonesian Population

Background: The relationship between food insecurity and the experience of sleep disturbance has received little attention among researchers, although food insecurity is associated with poor physical and mental health globally. This study aimed to investigate the relationship between food security status and sleep disturbance among adults 20–64 years old. Methods: The study’s population-based sample included 20,212 Indonesian adults who participated in the fifth wave of the Indonesia Family Life Survey (IFLS5) in 2014. Dietary intake data, gathered using a food frequency questionnaire (FFQ), were used to assess the food security status. Sleep disturbance was assessed using the 10-item Patient-Reported Outcomes Measurement Information System (PROMIS) questionnaire. We used multiple linear and logistic regression models to test the study hypothesis. Results: A higher likelihood of experiencing sleep disturbance was recorded in people aged older than 56 years (OR = 1.78, 95% CI: 1.17–2.72, p = 0.007), people with depressive symptoms (OR = 3.57, 95% CI: 2.77–4.61, p < 0.001), and food-insecure people (OR = 1.32, 95% CI: 1.02–1.70, p = 0.036). A lower likelihood of experiencing sleep disturbance was recorded in people with low educational attainment (OR = 0.41, 95% CI: 0.30–0.57, p < 0.001). Sleep disturbance was dependent on the food consumption groups and food security status among men (p = 0.004). Conclusions: Sleep disturbance may be affected by the food-insecure status of adults, and later, may lead to serious health outcomes.

Caregiver's Self-Confidence in Food Resource Management Is Associated with Lower Risk of Household Food Insecurity among SNAP-Ed-Eligible Head Start Families

Food resource management (FRM) behaviors are key components within nutrition education programs designed to help food insecure households maximize their food dollars. However, little is known about the association between FRM self-confidence and financial practices with household food insecurity (HFI) among families with young children. Using a sample of SNAP-Ed-eligible Head Start families, this study examined associations between FRM self-confidence, FRM behaviors and financial practices by HFI. A needs assessment survey was conducted with caregivers of Head Start children (n = 365). HFI was measured using the US Household Food Security Survey Module. Chi-square and logistic regression analyses were conducted to examine if FRM self-confidence, FRM behaviors, and financial practices differed by HFI. Participants with high FRM self-confidence had lower odds of HFI (OR = 0.54, 95%CI: 0.33, 0.87), yet FRM behaviors, financial practices, and HFI were not related after adjusting for covariates. All FRM self-confidence questions significantly differed by HFI, whereas only one of six FRM behaviors and two of three financial practices differed by HFI (all p-values < 0.05). Promoting caregivers' self-confidence in FRM skills within nutrition education programs may be explored as a potential strategy to assist low-income households to stretch their food dollars in an attempt to address HFI.
