With the increasing integration of renewable energy and smart technologies in residential energy systems, proactive household energy management (HEM) have become critical for reducing costs, enhancing grid stability, and achieving sustainability goals. This study proposes a ultra-short-term forecasting-driven proactive energy consumption optimization strategy that integrates advanced forecasting models with multi-objective scheduling algorithms. By leveraging deep learning techniques like Graph Attention Network (GAT) architectures, the system predicts ultra-short-term household load profiles with high accuracy, addressing the volatility of residential energy use. Then, based on the predicted data, a comprehensive consideration of electricity costs, user comfort, carbon emission pricing, and grid load balance indicators is undertaken. This study proposes an enhanced mixed-integer optimization algorithm to collaboratively optimize multiple objective functions, thereby refining appliance scheduling, energy storage utilization, and grid interaction. Case studies demonstrate that integrating photovoltaic (PV) power generation forecasting and load forecasting models into a home energy management system, and adjusting the original power usage schedule based on predicted PV output and water heater demand, can effectively reduce electricity costs and carbon emissions without compromising user engagement in optimization. This approach helps promote energy-saving and low-carbon electricity consumption habits among users. Full article

Background/Objectives: Ancient grains are increasingly recognized for their nutritional value, environmental sustainability, and connection to traditional agriculture. This study examines Italian consumers’ awareness, purchasing habits, and willingness to pay (WTP) for ancient grain pasta, focusing on the influence of product origin, price, and flour type on preferences. Methods: An online survey was conducted with 3020 Italian household grocery shoppers. Descriptive statistics assessed awareness and purchasing behavior, while conjoint analysis (CA) evaluated the relative importance of key product attributes (origin, price, and flour type) in pasta choices. The sample was segmented based on consumer knowledge of ancient grains. Results: A significant portion of respondents reported familiarity with ancient grains, perceiving them as “less refined” and “more digestible”; pasta emerged as the most purchased product. CA results indicated product origin as the most influential factor, followed by price, with flour type having comparatively lower influence. Notably, consumers more familiar with ancient grains showed a slight preference for ancient flour types and were less sensitive to price. Conclusions: While origin and price are primary drivers for pasta choices, knowledgeable consumers show greater valuation for flour type and accept higher prices. These findings provide strategic insights for stakeholders seeking to promote traditional, sustainable agri-food products through targeted marketing and transparent value communication. Full article

The growing mismanagement of energy resources is a pressing issue that poses significant risks to both individuals and the environment. As energy consumption continues to rise, the ramifications become increasingly severe, necessitating urgent action. In response, the rapid expansion of Internet of Things (IoT) devices offers a promising and innovative solution due to their adaptability, low power consumption, and transformative potential in energy management. This study describes a novel, integrative strategy that integrates IoT and Artificial Neural Networks (ANNs) in a smart monitoring mobile application intended to optimize energy usage and promote sustainability in residential settings. While both IoT and ANN technologies have been investigated separately in previous research, the uniqueness of this work is the actual integration of both technologies into a real-time, user-adaptive framework. The application allows for continuous energy monitoring via modern IoT devices and wireless sensor networks, while ANN-based prediction models evaluate consumption data to dynamically optimize energy use and reduce environmental effect. The system’s key features include simulated consumption scenarios and adaptive user profiles, which account for differences in household behaviors and occupancy patterns, allowing for tailored recommendations and energy control techniques. The architecture allows for remote device control, real-time feedback, and scenario-based simulations, making the system suitable for a wide range of home contexts. The suggested system’s feasibility and effectiveness are proved through detailed simulations, highlighting its potential to increase energy efficiency and encourage sustainable habits. This study contributes to the rapidly evolving field of intelligent energy management by providing a scalable, integrated, and user-centric solution that bridges the gap between theoretical models and actual implementation.

Background: Vietnam is experiencing a significant “double burden” of malnutrition, characterized by the persistent challenge of undernutrition, particularly stunting in ethnic minority and mountainous regions, alongside a rising prevalence of overweight and obesity. Understanding dual nutritional status and its related factors in adolescents from these vulnerable areas is crucial for effective intervention. Objective: The current study explored the nutritional status of ethnic minority secondary school students in some mountainous provinces in the northwest of Vietnam and identified some related factors. Methods: We conducted a cross-sectional study over six months (June–December 2023), involving 1847 ethnic minority high school students from Son La and Dien Bien provinces, recruited through convenience sampling in primary healthcare settings. Nutritional status was determined using WHO 2006 Child Growth Standards, specifically height-for-age Z-scores (HAZ) and body mass index (BMI)-for-age Z-scores (BAZ). A 4-point scale assessed nutritional practices, including food consumption frequency and eating habits. Results: This study identified a stunting (HAZ < −2 SD) prevalence of 16.7% and wasting (BAZ < −2 SD) of 5.6%; overweight/obesity (BAZ > +1 SD) prevalence was 8.2%. Key factors related to stunting were being male, having more siblings, poor/near-poor household economic status, low maternal education level, and frequent occurrences of gastrointestinal and respiratory diseases. A higher risk of overweight/obesity was associated with consuming more than three meals daily, nocturnal snacking, frequent intake of fried foods, insufficient consumption of vegetables and fruits, and inadequate daily physical activity. Conclusions: Our study shows a comprehensive picture of malnutrition among children in ethnic minority areas. Essential nutritional intervention programs, projects, and models are a top priority to reduce the disease burden for children’s bright future and to enhance socio-economic development in the mountainous regions of Vietnam.

Background: The current food system is unsustainable, making it essential to address the issue globally through adequate policies and sustainable development goals. The European Union aims to dedicate 25% of farmland to organic farming by 2030 to promote sustainable practices. Warsaw is the first Polish city working on an urban sustainable food policy; however, there is limited data on the sustainable food system (SFS) and organic sector available. Objectives: This research examines whether consumers in Warsaw who prefer organic food also display other sustainable characteristics and awareness, reflected in their food choices, dietary habits, and other food-related behaviors. Methods: A household survey (HHS) was conducted as part of the SysOrg project, focusing on evaluating the sustainability of food systems in Warsaw in the areas of diet and organic food. The clusters of respondents, grouped by the self-declared proportion of organic foods in their diets, were analyzed and compared, and in addition, correlation analyses of the share of organic food in diets and other sustainability parameters were performed. Results: The study of 449 respondents indicates that Warsaw is at an early stage of the organic transformation, with the largest group of respondents declaring a 1–10% share of organic products in their diet. There were significant differences in dietary choices, sustainability awareness, and food selection habits and motivations among various consumer groups depending on their organic food share. Conclusions: Overall, this study’s findings highlight a link between organic food consumption and certain sustainable behaviors, suggesting potential for organic consumers’ contribution to a sustainable transformation. The study offers valuable insights into the existing knowledge gap regarding the behaviors of organic and sustainable consumers in Warsaw. Furthermore, despite the non-random nature of the sample limiting the generalizability of findings, it serves as a preliminary resource for other European cities that are formulating food policies and incorporating Green Public Procurement (GPP) into their procurement processes, especially for municipalities within the Visegrad Group.

Objective: To characterize the nutritional status of the child population and to identify the most relevant determinants that could influence the early development of obesity and overweight. Methods: A descriptive cross-sectional study was conducted, recruiting a representative sample (698 schoolchildren, aged between 5 and 14, and obtaining information from a total of 414 households), using of anthropometric methods for nutritional assessment, the FIES scale, the KidMed index, and questions from the COSI survey. Results: Overall, 27% of the sample had healthy weight, 22.6% were overweight, and 18.1% were obese, with a higher prevalence among boys, and 86.7% of the sample did not adhere to dietary habits consistent with the Mediterranean diet. Food insecurity was present in 45.6% of the sample. A mean weight increase of 2.6 kg (95% CI: 1.0–4.3) was observed for each additional kilogram the child weighed at birth, 2.0 kg (95% CI: −0.2–4.3) in children living in households with some difficulty making ends meet, and 4.8 kg (95% CI: 1.3–8.3) in those from households reporting that they do not or barely manage to make ends meet. A statistically significant association was found with gross annual household income, with children from households earning less than EUR 12,000 having a 3.6 times higher risk of overweight/obesity compared to those from households earning more than EUR 36,000. Conclusions: The prevalence of obesity and overweight is considerably higher in low-income families and is significantly associated with family economic capacity. Continued epidemiological surveillance of these conditions and their relationship with social determinants is necessary. Full article

Background/Objectives: This study investigates the prevalence and impact of the double burden of malnutrition (DBM), malnutrition and overnutrition, in infants aged 0–24 months in the rural municipality of Ampefy, Itasy region, Madagascar. The Global Nutrition Report 2022 highlights the widespread issue of malnutrition, affecting 2 billion adults and 38 million children under five. Madagascar, characterized by severe poverty and high malnutrition rates, serves as a critical case study. Methods: A structured questionnaire was administered to 437 mother–child pairs from November 2022 to March 2023, collecting data on maternal education, dietary habits, and socio-economic status. Anthropometric measurements were taken using either a stadiometer or UNICEF length charts to assess height/length and an electronic scale to determine weight. Results: Findings reveal a high prevalence of malnutrition, with 29.7% of children affected by either wasting, stunting, and/or underweight, and 13.3% classified as overweight or obese. This study identifies significant age-related differences, with younger children more likely to be overweight and older children more likely to suffer from stunting or wasting. Maternal nutritional status, breastfeeding practices, and socio-economic conditions are strongly associated with child malnutrition outcomes. Lower dietary diversity among mothers and insufficient antenatal care are significant risk factors. Households with lower incomes and limited access to water and transport face higher malnutrition risks. Conclusions: This study underscores the critical need for targeted nutritional interventions and education to address DBM in Madagascar, highlighting the importance of maternal health and dietary diversity in early childhood development. Further longitudinal research is recommended to establish causality and develop comprehensive public health strategies. Full article

Indoor fungal communities, found in household dust, significantly influence indoor air quality and health. These communities are shaped by environmental, socioeconomic, and household factors. However, studies on indoor mycobiomes, particularly in Croatia, remain limited. This study investigates the relationship between environmental and household factors and indoor fungal communities, focusing on their diversity, composition, and potential health impacts in Croatian households. Dust samples from 66 Croatian households were analyzed using fungal ITS sequencing. Statistical analyses, including alpha diversity measures, were conducted to evaluate the influence of variables such as pet ownership, number of siblings, and cleaning habits on fungal diversity and abundance. Dominant genera included Malassezia, Cladosporium, and the family Didymosphaeriaceae. Pet ownership and sibling presence were linked to higher fungal diversity, with outdoor-associated genera such as Aureobasidium being more abundant in these households. Cleaning practices selectively altered fungal communities, with frequent cleaning reducing diversity, but not eliminating resilient taxa like Malassezia. This study highlights the interplay between environmental, household, and socioeconomic factors in shaping indoor fungal communities. The findings underscore the importance of addressing indoor fungal diversity to improve air quality and health, particularly in households with vulnerable populations. Full article

Food insecurity is a global challenge, particularly affecting developing nations. This study evaluated the role of home gardens in addressing food security in rural upland regions of Laos among three different types of vulnerable households. To address this objective, household survey data of project baseline 2019 (n = 504), midterm in 2021 (n = 425), and final 2022 (n = 435) were analyzed and tested. Additionally, focus group discussion (n = 3) and key informant interviews (n = 42) were carried out to gain deeper insights and triangulate and supplement household survey findings. The study found a 21% drop in food insecurity from 2019 to 2022, mainly due to a 12% increase in the number of home gardens, boosting crop production and harvests. We also found that dietary habits significantly improved between 2019 and 2022, with minimum diet diversity rising to 41% for three types of vulnerable households: 62% for female-headed households, 41% for households with disabilities, and 67% for other households. While there has been an improvement among different types of vulnerable households, about 15% of them still faced severe food shortages as of 2022. However, food insecurity among the three predetermined categories reveals significant disparities. Female-headed households experienced the most severe food insecurity and showed the least progress between 2019 and 2022. Additionally, we compared crop and diet diversity and various food insecurity coping methods across different time periods among these three vulnerable households. We provide several recommendations for targeted interventions and policies to address the remaining food security challenges in rural upland areas, ultimately contributing towards reducing global food insecurity.

Household savings are a long-term financial issue that can undermine the financial well-being of American families if not addressed. This study examines financial planning strategies through the Behavioral Life-Cycle (BLCH) hypothesis, focusing on long-term savings goals, financial safety nets, and foreseeable expenses. Using data from the 2022 Survey of Consumer Finances, a moderated mediation model explores how financial safety nets, self-control, and mental accounting influence saving habits. The findings show that long-term savings goals significantly mediate the relationship between financial safety nets and saving habits, while foreseeable expenses do not significantly moderate this relationship. These results highlight the importance of goal setting in promoting saving behaviors, regardless of specific financial needs. Policymakers can leverage these findings to design initiatives that encourage structured savings programs, while financial advisors should emphasize goal-setting strategies to help households improve their financial security. This research contributes to a deeper understanding of the behavioral and economic factors that drive personal savings, offering valuable insights for both policymakers and financial practitioners aiming to boost financial well-being in households.

Food consumption plays a fundamental role in human life, shaping not only daily nutrition but also economic and social behaviors. Household expenditures on food remain among the highest, and the time allocated to food purchasing and preparation is significant. Beyond biological necessity, food represents a cultural and social phenomenon, influencing consumer habits, market trends, and lifestyle choices. This study explores the key factors influencing purchasing decisions in the agro-food sector in the North-East Region of Romania, focusing on socio-cultural influences, product attributes, brand trust, tradition, and lifestyle. The research employs a quantitative approach, utilizing a structured questionnaire to collect data from 337 residents through a convenience sampling strategy. The collected data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) via SmartPLS 4.0 to examine the interrelationships between subjective norms, product attributes, price, consumer trust, and purchasing decisions. The findings indicate that social norms, price, product attributes, brand trust, customer satisfaction, and lifestyle have a significant and positive impact on consumer purchasing decisions. By understanding the key drivers behind sustainable food choices, businesses can optimize product offerings and enhance consumer engagement, while policymakers can design initiatives that promote sustainable consumption at both regional and national levels.

Background/Objectives: Vitamin D—crucial for bone health, immune function, and hormone regulation—is deficient worldwide, affecting around half the population, particularly women. The study aims to determine the prevalence and risk factors of vitamin D deficiency and hypovitaminosis D in non-pregnant women in Lebanon. Methods: A national cross-sectional survey sampled households across Lebanon, covering 2803 non-pregnant women aged 15 to 49. Demographic information and dietary habits were collected, and anthropometric measurements and serum analyses, including 25-hydroxyvitamin D (25(OH)D) concentrations, were conducted. Multivariable Poisson regressions were constructed to calculate the adjusted prevalence ratio (aPR) for vitamin D deficiency and hypovitaminosis D of variables. Results: The prevalence of vitamin D deficiency (<30 nmol/L) among non-pregnant women in Lebanon was 37.9%, while 69.2% had hypovitaminosis D (<50 nmol/L). Wearing a veil (hijab) was identified as the most significant risk factor for both vitamin D deficiency (aPR = 3.76) and hypovitaminosis D (aPR = 1.47). Additionally, olive skin and dark skin were both associated with an increased prevalence of vitamin D deficiency (olive skin: aPR = 1.14; dark skin: aPR = 1.28), while only dark skin color was associated with hypovitaminosis D (aPR = 1.10). In contrast, protective factors against vitamin D deficiency and hypovitaminosis D included daily sun exposure exceeding one hour (aPR = 0.83–0.91) and vitamin D supplementation (aPR = 0.30–0.55). Anemia, folate deficiency, and vitamin B12 deficiency were significantly associated with a higher prevalence of vitamin D deficiency, hypovitaminosis D, or both. BMI was not significantly associated with vitamin D deficiency; however, women with underweight (aPR = 1.13) and obesity (aPR = 1.12) exhibited a higher prevalence of hypovitaminosis D. Conclusions: Vitamin D deficiency and hypovitaminosis D affect a significant portion of non-pregnant women in Lebanon, with veiling (hijab wearing), limited sun exposure, and lack of supplementation as primary risk factors. Future work should focus on tailoring recommendations for vitamin D supplementation, sun exposure, and food fortification to effectively address the diverse risk factors in the population.

Background: There has yet to be an agreement on which specific socioeconomic status (SES) indicator most effectively reflects disparities in children’s diets. However, children from lower SES backgrounds are particularly vulnerable, as research in other countries indicates that their diets contain fewer fruits and vegetables and more sweetened beverages. This paper aims to evaluate the associations between dietary habits and various SES indicators (education, occupation, income, and household size) among a representative sample of children in Croatia aged 7–10. Methods: Parents of children were asked to complete a questionnaire that contained indicators of their children’s dietary habits and socioeconomic status (n = 5608). Associations between SES and children’s dietary habits were assessed using logistic regression models. Results: The mother and father’s educational attainment were strongly positively associated with breakfast consumption. Children of parents with a lower educational level consumed sweetened beverages, sweet snacks, and fast food slightly more often than children in families with a higher educational background. The mother’s education was inversely associated with vegetable and cereal consumption, while the father’s education was inversely associated with fruit and bakery product consumption. Meanwhile, household income per unit had a significant influence on the consumption of soft drinks and bakery products. Household size had a significant influence solely on sweet snack consumption. Conclusions: Each SES indicator showed an independent association with at least one particular dietary habit, except for the parent’s employment status. Full article
