Inadequate food and nutrition affect human well-being, particularly for many poor subpopulations living in rural areas. The purpose of this research was to analyze the factors that determine the Household Dietary Diversity Score (HDDS) in the rural area of the Paute River Basin, Azuay Province, Ecuador. The sample size of 383 surveys was determined by a stratified random sampling method with proportional affixation. Dietary diversity was measured through the HDDS, with 12 food groups (cereals; roots and tubers; fruits; sugar/honey; meat and eggs; legumes or grains; vegetables; oils/fats; milk and dairy products; meats; miscellaneous; fish and shellfish) over a recall period of 7 days. A Poisson regression model was used to determine the relationship between the HDDS and sociodemographic variables. The results show that the average HDDS of food consumption is 10.89 foods. Of the analyzed food groups, the most consumed are cereals; roots and tubers; fruits; sugar/honey. In addition, the determinants that best explain the HDDS in the predictive model were housing size, household size, per capita food expenditure, area of cultivated land, level of education, and marital status of the head of household. The tools used in this research can be used to analyze food and nutrition security interventions. Furthermore, the results allow policymakers to identify applicable public policies in the fight against hunger.

Households’ food access remains a concern primarily in rural households in lower- and middle-income countries. The purpose of this study is to measure food access and to identify the coping strategies in indigenous households of the communities of Sierra Tarahumara in Mexico. The representative sample was made up of 123 households from 38 communities. The survey was conducted face to face during the winter season between February and March 2015. Since all respondents only speak the Tarahumara language, authors were assisted by translators. The level of access to food was low in 54.47% of households. The main coping strategies used by households were rationing and augmenting short-term household food availability. Bivariate analyses were used, with Chi-square ( χ 2 ) test suggesting that coping strategies associated with food access included: reliance on less expensive foods, purchasing food on credit, limiting portion size at meal times, skipping meals, and restricting consumption of adults to secure children’s intake. One-way analysis of variance (ANOVA) test indicated that the income derived from various households are identical across all food access levels. We conclude that the indigenous households did experience difficulties in obtaining food.

Eliminating food insecurity is one of humanity’s greatest global challenges. Thus, the purpose of this research was to analyze the factors that determine food insecurity in households in the rural area of the Paute River Basin, Azuay Province, Ecuador. Stratified sampling was used as the sampling method, with proportional affixation. Moreover, we employed the Latin American and Caribbean Household Food Security Measurement Scale (ELCSA). We estimated the main determinants of household food insecurity using two binomial logit models and one ordered logit model. For the analysis of the data, the respective statistical and econometric tests were employed. The results show that housing size and access to food security information are the most important determinants of food insecurity in the three predictive models applied in this research. This research contributes to the existing literature on food insecurity and provides important information for policymakers, especially regarding food insecurity in rural areas, which has profound economic and social implications.

Food security is a condition that allows people permanent access to food for a better quality of life; therefore, it is a priority for the economic development of countries. In this context, this research aims to determine the importance of purchasing power and education in the food security of families in rural environments using Chambo canton, Ecuador as a case study. Considering the deductive method, the research is descriptive correlational, with a qualitative and quantitative approach. For data collection, a questionnaire based on the Latin American and Caribbean Food Security Scale was applied to 230 households out of a total of 3585 households. The results showed that the variables of number of income earners and total family income have a high relationship with food security, unlike level of schooling. It was concluded that education does not represent a decisive factor for food security in rural environments, although its incorporation as a variable is important for improving quality of life.

Por otro lado, la seguridad alimentaria nace en los 70s, tomando en cuenta la producción y disponibilidad alimentaria a nivel nacional y mundial; mientras que en los 80s se amplió al acceso, tanto físico como económico de los alimentos, y en los 90s se obtuvo el concepto presente que incluye a la inocuidad, preferencias culturales, y se ratifica como un derecho humano. Por tanto, conforme a la Organización de las Naciones Unidas para la Agricultura y la Alimentación (FAO), a partir de la Cumbre Mundial de la Alimentación (CMA) de 1996, la seguridad alimentaria “existe cuando todas las personas tienen, en todo momento, acceso físico, social y económico a alimentos suficientes, inocuos y nutritivos que satisfacen sus necesidades energéticas diarias y preferencias alimentarias para llevar una vida activa y sana”8,11.

Food insecurity is a critical issue in the Americas, with severe impacts in the Caribbean, Mesoamerica, and South America, particularly affecting older adults in Indigenous and rural contexts where it intersects with poverty, gender, and ethnicity. This study aims to provide an in-depth understanding of the current research about food insecurity among older Indigenous adults in Latin America and the Caribbean. A comprehensive literature review was conducted, utilizing specific search queries and the population, intervention, comparison, and outcome (PICO) strategy across multiple databases to identify the pertinent studies. The findings indicate an increase in academic output on this topic since 2018, with significant emphasis on the interplay between climate change and food insecurity. The review highlights the importance of developing targeted food programs, reforming policies, and fostering collaboration between academia and local communities to implement practical interventions. Despite the growing body of literature, a notable research gap persists in rural areas of Latin America and the Caribbean. This study underscores the necessity of balancing the geographic distribution of research and emphasizes the preservation of cultural practices and the adaptation of public policies to support traditional food practices. It advocates for culturally sensitive interventions and interdisciplinary collaboration to formulate comprehensive strategies. The originality and value of this study lie in its focused analysis of older Indigenous adults, contributing crucial insights to the international literature on food security.
