Associação de insegurança alimentar e nutricional com fatores de risco cardiometabólicos na infância e adolescência: uma revisão sistemática

Child meal support program, food and nutrition insecurity, and health among Korean children

BACKGROUND

Korea's child meal support program (CMSP) aims to reduce food and nutrition insecurity (FNI) and improve health among children from low-income households.

AIM

We examined the impact of different types of CMSP on children's FNI and health in Korea, analyzing meal frequency and healthful food consumption (FNI), and general health and depression (health) among child meal card (CMC) and facility meal service (FMS) participants compared with nonparticipants.

METHODS

The 2018 Comprehensive Survey on Korean Children data were analyzed. Precisely, 847 children from low-income households aged 9-17 were categorized into CMC (n = 331), FMS (n = 209), and income-eligible nonparticipants (n = 307). Propensity score-weighted generalized linear models assessed CMSP's impact on FNI and health. Stratified generalized linear models examined heterogeneity in FNI-health associations by CMSP status.

RESULTS

CMC participants reported more frequent breakfast consumption (odds ratio [OR] = 0.662, p < 0.05) but poorer self-rated general health (OR = 1.890, p < 0.05); FMS participants were less likely to have three meals (OR = 1.814, p < 0.05), fruits and vegetables (OR = 2.194, p < 0.001), and protein-rich foods daily (OR = 1.695, p < 0.05) than nonparticipants. Health risks associated with healthful food consumption and meal frequency were more pronounced among CMC and FMS/nonparticipants, respectively.

CONCLUSION

CMSP had a limited impact on reducing FNI and improving health among children from low-income households. CMC appeared more effective than FMS in alleviating FNI, notwithstanding potential health concerns. Food assistance programs should seek comprehensive enhancements in children's food and nutrition security and health.

Prevalence of the metabolic syndrome by household food insecurity status in the United States adolescent population, 2001-2020: a cross-sectional study

BACKGROUND

Household food insecurity (FI) is a modifiable social determinant of health linked to chronic health outcomes. Little is known, however, about the prevalence of metabolic syndrome (MetS) in pediatric population-based studies by household FI status.

OBJECTIVES

The objective of the study was to estimate the prevalence of the MetS by household FI status over the past 2 decades.

METHODS

This cross-sectional study used data from the 2001-2020 National Health and Nutrition Examination Survey (NHANES). Participants were nonpregnant adolescents ages 12- 18 y in United States. The prevalence of MetS [elevated waist circumference and >2 of the following risk factors: elevated blood pressure, and fasting glucose, triglyceride, and/or low high-density lipoprotein (HDL) cholesterol concentrations] by FI status was evaluated using chi-square and logistic regression analyses.

RESULTS

The estimated prevalence of MetS was 2.66% [95% confidence interval (CI): 2.28%, 3.09%] in the final analytical sample (unweighted N = 12,932). A total of 3.39% (95% CI: 2.53%, 4.53%) of adolescents from FI households had MetS compared to 2.48% (95% CI: 2.11%, 2.9%) among adolescents with no household FI. Hispanic adolescents had the highest prevalence of MetS (3.73%, 95% CI: 3.05, 4.56) compared with adolescents who identified as non-Hispanic White (2.78%, 95% CI: 2.25, 3.43), non-Hispanic Black (1.58%, 95% CI: 1.19, 2.10). Adolescents with household FI (23.20%) were more likely to have MetS [odds ratio (OR): 1.38; 95% CI: 1.02, 1.88; I=0.039) compared with adolescents with no household FI, but in fully adjusted models this was not significant (OR: 1.13; 95% CI: 0.75, 1.72).

CONCLUSIONS

Using the most current NHANES data, the estimated prevalence of MetS in adolescents in United States was slightly higher among those from FI households. However, after adjusting for potential confounders, the relationship between household FI and MetS was nonsignificant, highlighting the complexity of factors contributing to MetS in this population. Hispanic adolescents share a disproportionate burden of MetS compared with their non-Hispanic counterparts.

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.

Biochemical markers and anthropometric profile of children enrolled in public daycare centers

OBJECTIVE

The nutritional status resultant from dietary habits along with socioeconomic conditions and the school environment are directly related to the individual's health condition not only in their childhood but also throughout adulthood. The aim of this study was to evaluate the effects of socioeconomic factors on the anthropometric profile and to analyze a probable association between this profile and biochemical markers in children attending public daycare centers.

METHODS

It is a transversal study developed in a probability sample of clusters of children from 6 months to 5 years old. Anthropometric and socioeconomic data were gathered at the CMEIs, questionnaires on the nutritional status were applied and blood was collected at the Family Health Units (USFs).

RESULTS

Female children are three times more likely to be underweight; in families with five members, it is 1/3 more likely that children of higher-educated parents are overweight. Among the results of the biochemical tests, hypervitaminosis A was a relevant aspect, positively correlating with copper (p=0.005) and zinc (p=0.008).

CONCLUSION

Therefore, since the influence of the family is an important predictor of overweight and its future outcomes related to nutritional deficiencies and inadequate dietary intake, educational interventions are vital as a way to pave the path to prevention.

Hungry is not safe: A mixed methods study to explore food insecurity in early care and education

The early care and education (ECE) environment has the potential to affect both children and their families. Food insecurity in ECE and its management may be an important influence. Objectives of this mixed methods study were to (1) elicit prominent themes relating to teacher experiences with food insecurity (in the classroom) through qualitative interviews; (2) translate interview themes into survey items and analyze survey data to explore generalizability of the qualitative findings; and (3) provide preliminary data on properties of a new tool to study the influence of food insecurity in the ECE setting. An exploratory sequential mixed methods design (QUAL → quant) was used. Twenty-eight interviews about teacher experiences with food insecurity were followed by 781 surveys to assess generalizability of interview findings. Qualitative themes highlighted that ECE teachers are concerned about children's food insecurity in their classroom; ECE teachers have developed their own set of strategies to manage their concern; and teachers often struggle with what to do. Quantitative results demonstrated many teachers had the same concerns and used the strategies described in the interviews. Further, in exploratory analyses, ECE teachers with Food Insecurity scored significantly higher on all scales (e.g., Food Insecurity Concerns, Struggle with Addressing Food Security) in both adjusted and unadjusted analyses. ECE teachers with Food Acquisition Stress had higher scores on Strategies to Address Food Insecurity with Families in adjusted analyses.

Association between food insecurity and cardiometabolic risk in adults and the elderly: A systematic review

Background

Food insecurity is a public health concern that affects health and quality of life, but its association with cardiometabolic risk is not well established. Thus, this systematic review evaluated the association between food insecurity and cardiometabolic risk factors in adults and the elderly.

Methods

Search was conducted according to the PRISMA protocol using Scielo, LILACS and PubMed databases. We included original articles published in Portuguese, English, and Spanish, which assessed the association between food insecurity and cardiometabolic risk factors in adults and the elderly. The search identified 877 articles but only 11 were included in the review.

Results

Food insecurity was directly associated with cardiometabolic risk (excess weight, hypertension, dyslipidemias, diabetes, and stress) after adjusting for interfering factors. A limitation of the cross-sectional study design is that the cause-effect relation between food insecurity and cardiometabolic risk cannot be established.

Conclusions

We conclude that food insecurity has a direct relationship with cardiometabolic risk factors, especially excess weight, hypertension, and dyslipidemias. The identification of food insecurity as health problems can contribute to the implementation of efficient public policies for the prevention and control of chronic diseases.

Methodologies for assessing the household food availability in the context of food (in)security: a systematic review

This article aims to identify the methods used to assess household food availability in studies on food and nutritional security and to discuss its methodological aspects. Systematic review elaborated according to the PRISMA method. We searched at PubMed; Scielo and Lilacs databases, and studies that used methods of assessing the availability of food at home were included. In the end, 19 papers composed the review. Food availability was predominantly assessed for a seven days period and from a single data measurement. Other variables were also observed in the studies, such as socio-demographic data and expenditure on food. Among the limitations to assess the food availability at home, we can highlight the difficulty in measuring the food distribution among family members and the lack of information on the variability of this availability. Such assessment can be improved by investigating the strengths and weaknesses of the instruments for greater detail and accuracy of the information. We recommend the development and validation of specific instruments capable of effectively measure the food availability at the household level.

Food Insecurity and Bullying Victimization Among 170,618 Adolescents in 59 Countries

Background: Bullying victimization can impose long-lasting impacts on adolescent's current and subsequent well-being. Understanding the correlates of bullying victimization and how to prevent its occurrence is an urgent need. Food insecurity, an indicator of low socioeconomic status, may be related to bullying victimization. However, research on the association between food insecurity and bullying victimization is limited. Using a representative global sample, this study aimed to investigate the association between food insecurity and bullying victimization in adolescents and whether the association varied between country income levels, sexes, and age groups. Methods: Using cross-sectional, school-based data by 170,618 adolescents in 59 countries from the Global School-based Student Health Survey, multivariable logistic regression and meta-analysis were conducted to investigate the overall, country-stratified, sex-stratified, and age-stratified associations. Results: The prevalence of bullying victimization was 33.3%. In the total sample, adolescents with food insecurity showed significantly higher odds for bullying victimization than those without no food insecurity with a pooled odds ratio (OR) being 1.37 (1.28, 1.47). Further, the association was stronger in higher-income countries, females, and older adolescents. Conclusions: Bullying victimization is prevalent among global adolescents with food insecurity being a significant correlate. The identification of adolescents with perceptions of food insecurity and remedying this condition may be important to reduce the prevalence of bullying. This highlights the need to design and implement sex- and age-specific interventions focusing on remedying food insecurity and bullying victimization among in-school adolescents by taking country income levels into account.

Prevalence, socio-economic predictors and health correlates of food insecurity among Italian children- findings from a cross-sectional study

Considering food insecurity is a problem, even in developed countries, and the evidence gap regarding this issue in Italy, we aimed to assess the prevalence of food insecurity in a sample of Italian children and examine socio-economic and health correlates. This cross-sectional study was conducted in paediatric practices. Parents answered to the 18-items of the Household Food Security Module, 8 of which concern children. Paediatricians answered a questionnaire on children’s health. Socio-economic and health correlates of food insecurity in children were assessed using univariable and multivariable logistic regression. Among 573 households with children, 15·4% were food insecure, while 9·1% of children were food insecure. Socio-economic factors associated to food insecurity were living in south Italy, households with three or more children, lower household yearly income, worse economic situation description and younger parents. Food insecure children were less likely to have a normal relational [ aOR 0.31 (CI 0.11-0.85)] and physical development [aOR 0.32(CI 0.15-0.65) and had more school difficulties [aOR 3.1(CI 1.33-7.24)] compared to their food secure peers. Food insecure children had higher odds of a deterioration in their health since birth and of a worse perceived health status, as reported by their parents. Considering the results in this sample and the lack of research regarding this issues in Italy and Europe more broadly, we call for consistent, national monitoring to determine the magnitude of the problem of food insecurity in households with children in Italy and to examine the socio-economic variables and health implications in different contexts.

Food availability and food insecurity in households in the state of Tocantins, Northern Brazil

ABSTRACT Objective To assess the relationship between food availability, food insecurity and socioeconomic and demographic characteristics of households in the urban area of the state of Tocantins. Methods Population-based, cross-sectional study conducted in 594 households in the urban area of 22 municipalities in the state of Tocantins. A survey was carried out in the households, to collect socioeconomic and data, and assess food insecurity using the Brazilian Food Insecurity Scale. Further a food availability questionnaire was applied by the interviewer with the head of the family, who reported on the food and drinks available at home in the last 30 days. The description of the food available in the households resulted in a total of 142 food items that were grouped according to the NOVA classification of foods. demographic Results It was found that 63.3% of households were in a situation of food insecurity. The median caloric availability found was 2,771.4kcal/per capita/day, with the largest caloric contribution coming from fresh and minimally processed foods, regardless of the degree of food insecurity. Food availability was affected by socioeconomic vulnerability and the situation of food insecurity in the families.

Processed and ultra-processed foods are associated with high prevalence of inadequate selenium intake and low prevalence of vitamin B1 and zinc inadequacy in adolescents from public schools in an urban area of northeastern Brazil

Changes in eating behavior of adolescents are associated with high consumption of processed and ultra-processed foods. This study evaluated the association between these foods and the prevalence of inadequate micronutrient intake in adolescents. A cross-sectional study was conducted with 444 adolescents from public schools in the city of Natal, northeastern Brazil. The adolescents' habitual food consumption was evaluated using two 24-hour dietary recalls. Foods were categorized according to the degree of processing (processed and ultra-processed) and distributed into energy quartiles, using the NOVA classification system. Inadequacies in micronutrient intake were assessed using the estimated average requirement (EAR) as the cutoff point. Multivariate logistic regression models were used to estimate the relationship between energy percentage from processed and ultra-processed foods and prevalence of inadequate micronutrient intake. The mean (Standard Deviation (SD)) consumption of total energy from processed foods ranged from 5.8% (1.7%) in Q1 to 20.6% (2.9%) in Q4, while the mean consumption of total energy from ultra-processed foods ranged from 21.4% (4.9%) in Q1 to 61.5% (11.7%) in Q4. The rates of inadequate intake of vitamin D, vitamin E, folate, calcium, and selenium were above 80% for both sexes across all age groups. Energy consumption from processed foods was associated with higher prevalence of inadequate selenium intake (p < 0.01) and lower prevalence of inadequate vitamin B1 intake (p = 0.04). Energy consumption from ultra-processed foods was associated with lower prevalence of inadequate zinc and vitamin B1 intake (p < 0.01 and p = 0.03, respectively). An increase in the proportion of energy obtained from processed and ultra-processed foods may reflect higher prevalence of inadequate selenium intake and lower prevalence of vitamin B1 and zinc inadequacy.

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

OBJECTIVE

To examine the association between food insecurity and child sleep outcomes and to investigate whether parent psychosocial factors mediate such associations.

DESIGN

Cross-sectional study. Usual wake time and bedtime, bedtime routine and sleep quality were reported by parents using the adapted Brief Infant Sleep Questionnaire. Food insecurity was assessed using the eighteen-item US Department of Agriculture Household Food Security Module. Parent psychosocial factors, including perceived stress, parenting self-efficacy and depressive symptomology, were assessed using validated scales. Multivariable logistic regression models were performed to determine the association between food insecurity and sleep outcomes controlling for potential confounders. Mediation analyses and Sobel tests were applied to test the mediating effect of psychosocial factors.

SETTING

Head Start pre-school classrooms in four regions across central Pennsylvania, USA.

PARTICIPANTS

Low-income children of pre-school age (n 362) and their caregivers.

RESULTS

Prevalence of household, adult and child food insecurity was 37·3, 31·8 and 17·7 %, respectively. Food security status at any level was not associated with child sleep duration or bedtime routine. Child food insecurity, but not household or adult food insecurity, was associated with 2·25 times increased odds (95 % CI 1·11, 4·55) of poor child sleep quality in the adjusted model. Perceived stress, self-efficacy and depressive symptomology mediated less than 2 % of the observed effect (all Sobel test P > 0·6).

CONCLUSION

Food insecurity, particularly at the child level, is a potential modifiable risk factor for reducing sleep-related health disparities in early childhood. Future studies are needed to explore the plausible mechanisms underlying the associations between food insecurity and adverse child sleep outcomes.

Relationship between food insecurity and high blood pressure in a national sample of children and adolescents

OBJECTIVES

To determine the relationship between food insecurity (FI) and high blood pressure (BP) in a national cohort of children and adolescents.

METHODS

A cross-sectional analysis of children aged 8-17 years in the 2007-2014 National Health and Nutrition Examination Survey (NHANES; unweighted N = 7125). FI over the preceding 12 months was assessed using the USDA Household Food Security Scale in NHANES. We defined high BP as (i) systolic or diastolic BP ≥ 90% for age < 13 years or ≥ 120/80 mmHg for age ≥ 13 years measured at one visit or (ii) reported hypertension diagnosis or current antihypertensive medication use. We used multivariable logistic regression to determine the association between household and child-specific FI and high BP, controlling for age, sex, race, and household income, accounting for the complex NHANES survey design.

RESULTS

The study population was 14.4% black, 21.3% Hispanic, and 49.4% female with a mean age of 12.6 years (SD 2.9). 20.3% had FI and 12.8% had high BP. High BP was more common in household FI vs. food-secure subjects (15.3% vs. 12.1%, p = 0.003). Adjusted analysis confirmed that household FI and child FI were associated with high BP (OR 1.26, 95% CI 1.04-1.54; OR 1.42, 95% CI 1.03-1.96, respectively).

CONCLUSIONS

Household and child FI were associated with an increased likelihood of high BP in a large nationally representative cohort of children and adolescents. FI may have a significant impact on cardiovascular health during childhood. Further research is warranted to better define how FI contributes to health disparities.

[Gender, food and nutrition security and vulnerability: the Thousand Women Program in focus]

Gender inequality is revealed in the issues of education, income and access to Food and Nutrition Security. In Brazil, the National Women Thousand Program aims to intensify the process of regional and institutional development by improving the access of women in situations of social vulnerability to education and the world of work. The objective is to analyze the contribution of the Programa Nacional Mulheres Mil's to reduce vulnerability to food insecurity of households headed by woman. A semi-structured questionnaire was applied to 384 participants, which contained the demographic and socioeconomic variables as well as the Brazilian Food Insecurity Scale. It was observed that, although there was no change in the Food Security situation, there were significant differences in relation to income, especially among women in situation of food insecurity, varying from 20.5% to 46% the number of participants with an income range higher than one minimum wage. The advance in the identified income was not enough to intervene in Food Insecurity. Further research should be carried out in order to deepen the understanding of the relationships between income, education and food and nutritional security, especially from the point of view of actions directed at the female gender.
