    Child and maternal nutrition are essential to any country's food and nutrition security, encompassing all the components of maternal and child growth, well-being, development, and productivity, as contained in the modified UNICEF 2020 conceptual framework on determinants of maternal and child nutrition. According to the World Health Organization (WHO) and Centers for Disease Control and Prevention (CDC), preschool children are regarded as being between 3 and 5 years old. This period entails intensive cognitive development in children, where developmental milestones that help shape their personality, interpersonal relationships, and thinking patterns are fostered; hence, the need to consume healthy meals following the recommended minimum dietary diversity requirements of at least five to eight food groups per day for children is a bedrock for positive health outcomes. The prevalence of nutrition-related maternal and child morbidity has continued to increase in recent times across many low- and middle-income countries (LMICs) owing to several complex multifactorial and interrelated determinants. The complexity and interconnectedness of the determinants of maternal and child nutrition in developing countries, such as Nigeria, are yet to be well conceptualised and have become a public health issue due to the emerging triple burden of malnutrition (TBM) and the prevalence of diet-related non-communicable diseases ravaging the nation. Therefore, this study assessed the food and nutrition security status of mothers and their preschoolers in North Central Nigeria. A cross-sectional descriptive design and a multi-stage sampling technique were used to recruit 450 mother-child pairs (preschool children aged 3-5 years) across the North South senatorial district in Niger State, North Central Nigeria. Sociodemographic information and biodata of mothers and their preschoolers were collected using semi-structured questionnaires. Feeding patterns of mother-child pairs were assessed using a qualitative food frequency questionnaire based on 24-hour and 7-day dietary recall. The dietary diversity of households, mothers, and children was assessed using the Household Dietary Diversity Score (HDDS), Minimum Dietary Diversity Score for Children (MDD_C), and Minimum Dietary Diversity Score for women of reproductive age (MDD_W), respectively, as recommended by the Food and Agriculture Organization (FAO), Family Health International (FHI) and World Health Organization (WHO). The Household Food Insecurity Access Scale (HFIAS) was used to assess the food insecurity status of the participants. Anthropometric indices of the preschoolers were assessed based on weight-for-age, height-for-age, and weight-for-height indicators, while maternal anthropometry was assessed using body mass index (BMI) and waist/hip ratio. Maternal nutrition knowledge was assessed using a Likert-type scale. Retrieved information was analysed using SPSS version 28. Descriptive statistics are presented in tables and charts, while regression models were used for inferential statistics, with statistical significance being considered at a 95% confidence interval with a p-value of < 0.05. The study was conducted in two phases: the first phase considered an in-depth narrative literature review that evaluated the food and nutrition security status of preschool children in North Central, Nigeria, as well as the food insecurity and vulnerability of the food environment among Nigerian mothers. This study explored the literature using a qualitative approach and an overview of online sources, peer-reviewed articles, books, and other publications and relevant reports from official websites to investigate the concept of the food environment, food acquisition and utilisation complexities among Nigerian women, and the prevalence of food and nutrition insecurity and its determinants among preschool children. This review found that the global prevalence of the Triple Burden of Malnutrition (TBM) is alarming, especially among developing nations, affecting more women than men. Food acquisition and utilisation are important determinants of women’s food and nutritional security status. Full but empty plates have continued to be a dilemma among women from countries undergoing urbanisation and nutrition transitioning; hence, poor nutrient intake has been reported to account for the high risk of maternal morbidity and mortality related to nutritional causes in most developing countries, such as Nigeria. This revealed that the interconnectedness of the food environment to food acquisition and utilisation in addressing food insecurity and malnutrition as an innovative concept is yet to be well understood and explored in many studies across Nigeria. It also elucidates the drivers of poor dietary diversity, meal quality, and food consumption patterns among preschool children and possible health outcomes of compromised feeding patterns and the risk of non-communicable diseases and malnutrition among the study participants. In addition, the review also focused on the drivers of the food environment, food acquisition, nutrient utilisation, and the prevalence of TBM among women across the six geopolitical zones in the country. The high prevalence of malnutrition and diet-related noncommunicable diseases in this study accounts for the high maternal and child morbidity and mortality rates, especially in many rural and poor households across the nation, thus becoming a significant public health concern. Some factors found to significantly impact food utilisation among women were food literacy, poverty, insurgence, lack of support systems, seasonality, and family size. To mitigate these challenges, efforts should be geared towards improving both the community and consumer food environments, thus ensuring the consumption of nutrientdense meals for optimal health outcomes and well-being, especially among women and preschool children living in rural areas, urban slums, and low-income households across the six geopolitical zones of the nation and among other developing nations experiencing food and nutrition insecurity around the world. The second phase was the experimental section and was divided into two parts: the first part explored the socioeconomic status, household food security status using the HFIAS and the feeding patterns of the preschool children using the qualitative 24 hour and 7-day dietary recall. Dietary diversity was assessed using the MDD_C, while the anthropometric indicators for under-five children were used to categorise the children into stunting, wasting, underweight, and normal weight. The results showed that the majority (76.4%) of the preschool children were from rural communities; more than half (51.8%) of the children were from mothers who had only Islamic education (no formal education), and only a few (1.2%) of the children were born to single mothers. Almost all (95.6%) of the children were from Islamic religious homes, and the majority (71.6%) of the mothers were unemployed, while 83.8% of the monthly household income was below N18,000 ($40), which is far below the national minimum income range of N36,000. Most (73.6%) of the children were from male-headed households. The predominant ethnic group was Nupe (68.4%), whereas the least dominant was Gwari (<1%). Most (98.8%) of the preschool children were from food-insecure households, and almost half (42.4% and 40.2%) of the preschool children were either moderately food insecure or severely food insecure, respectively. The severity of food insecurity increased with parity, and its prevalence was higher among children from multiparous and grand multiparous households. The most consumed food group among preschoolers was cereal-based food products, while the least consumed food groups were fruits and vegetables. This study also showed that over half (60.0%) of the preschoolers did not meet the minimum dietary diversity score (MDD_C) recommended for their age. The anthropometric indices of the preschool children showed that half (50.0%) of the children were stunted (height-for-age), 21.0% had wasting (weight-forheight), and 29.0% were underweight (22.2% were severely underweight) (weight-for-age). The logistic regression model showed that the socioeconomic status of mothers, such as education, income, religion, occupation, employment status, means of waste disposal, source of potable water (water suitable for human consumption), and water treatment methods, were associated with the household food insecurity status of the children and were associated with inadequacy in children’s MDD (p < 0.05). The second part of the experiment explored the contribution of maternal nutrition literacy to the nutritional status of mothers in Niger State, North Central Nigeria. The results showed that the majority (63.8%) of the mothers were between 26 and 35 years old. More than half (51.6%) of the mothers did not know what a balanced diet was based on the definitions provided in the questionnaire. Social media or online information was the most explored source of nutritional information among mothers (36.4 %). Fifty-four per cent of the mothers indicated that their nutrition literacy had no positive impact on their dietary quality. The food consumption pattern showed that fruits/vegetables, and dairy products were the least consumed food groups among the mothers (7.1% and 9.1%, respectively). More than half (57.6%) of the mothers were within the normal BMI range, and the mean waist/hip ratio was 0.82 ± 0.08. The regression model showed that place of residence, occupation, source of potable water, and method of waste disposal were significantly associated with adequacy of maternal minimum dietary diversity. Although nutrition knowledge has been reported to influence dietary quality among mothers, this study showed that other intrinsic factors besides nutrition knowledge significantly impacted the dietary quality and nutritional status of mothers in the study area. Therefore, to optimise health outcomes among mothers, stakeholders at all levels must implement programs and policies that address issues such as insurgence, inflation, climate change, disparity in wealth distribution, and seasonal vulnerability. In conclusion, the prevalence of food and nutrition insecurity was high among the participants due to poor socioeconomic status and poor food environment, thereby compromising the meal quality and consumption frequency of mothers and their preschoolers. Most mothers adopted the consumption of ultra-processed foods and beverages as coping strategies to salvage the impact of hunger and starvation, thereby predisposing them to the risk of TBM and NCDs among mothers and their preschool children. To mitigate these challenges, efforts should be geared towards addressing the determinants of food and nutrition insecurity with a multidimensional approach at the grassroots level and involving all stakeholders and policymakers, to enable a sustainable food system through nutrition-sensitive agriculture at the household and community level. Draught resistant and improved variety crops should be used to mitigate climate change impact on food access and affordability and thus, enhance adequate consumption of nutrient-dense meals for optimal health outcomes among the participants and across most food insecure developing nations. IQOQA Ukudla kwezingane nomama kuyisibikezelo sanoma yisiphi isimo sokungavikeleki kokudla ezweni, ifood and nutrition insecurity status (FNIS). Ukuvela komthwalo ophindwe kathathu wokungondleki, itriple burden of malnutrition (TBM); ukusabalala kwezifo ezingatheleleki ezihlobene nokudla kanye nokufa phakathi kwabesimame nezingane zasenkulisa eNigeria kuyinto ekhathaza kakhulu impilo yomphakathi. Lolu cwaningo luhlole isimo sokuphepha kokudla nokudla kwabesimame nezingane zasenkulisa eNorth Central Nigeria. Kwasetshenziswa inqubo yokusampula yezigaba eziningi ukuqasha amabhangqa anga-450 omama nezingane kulo lonke elaseNiger State, eNigeria. Imibuzo ehlelekile kanye nezingxoxo zeqembu lokugxila zasetshenziselwa ukubuyisa ulwazi ngesociodemographic, ibiodata, iphethini yokudla, ukudla kwasendlini isimo sokuphepha, ulwazi lokudla kwabesimame, ukuhlukahluka okuncane kokudla, kanye nezinkomba ze-anthropometric zabomama / abanakekeli kanye nezingane zabo zasenkulisa. Imininingwane eyatholakala yahlaziywa ngokusebenzisa i-SPSS version 28, futhi ukubaluleka kwezibalo kwabekwa kumaphesenti angama-95 kwesikhawu sokuzethemba kanye ne-p-value < 0.05. Lolu cwaningo luveze ukuthi amaphesenti angama-76.4 womama nezingane zabo zasenkulisa bavela emiphakathini yasemaphandleni, kanti amaphesenti angama-83.8% emali abayithola emakhaya ngenyanga ingaphansi kuka-N18 000 ($40). Iningi (98.8%) labahlanganyeli babevela emakhaya angenakudla, futhi cishe isigamu (42.4% no-40.2%) sasinokudla ngokulinganisela okungaphephile noma okungaphephile kakhulu, ngokulandelana. Amaphesenti angamashumi ayisithupha (60.0%) ezinganeni zasenkulisa azizange zihlangabezane nokuhlukahluka okuncane kokudla (MDD_C). Iphethini yokusetshenziswa kokudla kwabahlanganyeli yabonisa ukuthi izithelo / imifino (7.1%) kanye nemikhiqizo yobisi (9.1%) kwakungamaqembu okudla angadliwa kakhulu, kanti ukudla okunesitashi (53.1%) kwakuyikona okungamaqembu okudla okudliwayo. Iningi lomama (57.6%) babengaphakathi kwebanga elijwayelekile le-BMI, kanti amaphesenti angama-50.0 ezingane zaphazamiseka. Amaphesenti angamashumi amahlanu nane (54%) omama babenolwazi oluphansi lokudla okunomsoco. Kwakukhona ukuhlangana okuqinile phakathi kwesimo sezenhlalo nezomnotho somama / abanakekeli kanye nesimo sokungavikeleki kokudla kwasendlini, izinkomba ze-anthropometric kanye nokwanela kwe-MDD yabahlanganyeli (p < 0.05). Ngakho-ke, kumele kuhlolwe izindlela eziningi zokubhekana nesimo sokungavikeleki kokudla nokudla phakathi kwalaba bantu abasengozini.
