[Contributions of urban planning for more food security in German cities]. / Beiträge kommunaler Planung für mehr Ernährungssicherheit in deutschen Städten.

Many German municipalities are developing retail concepts for retail management and taking stock of the food supply is one of the standard tools. A distance-based indicator is commonly used, which measures the degree of supply based on linear distances between the place of residence and the nearest place of purchase. Beyond this distance, however, access to food is influenced by other spatiophysical and socioeconomic factors. So far, these have hardly been considered. Inadequate access to food is not only problematic from a health perspective, but also because of the social function of food as an important field of social participation. Difficult access to food especially affects people in precarious circumstances, who are already restricted in their participation in society. This article therefore presents a model that theoretically informed, comprehensively and systematically captures the spatiophysical and socioeconomic embedding of food access. Based on selected results of a study that was carried out in Bremen using this approach, this article shows the access barriers that affect residents of two districts that are considered to be well supplied. The primary goal of this article is to raise awareness of the complex issue of food access. Finally, approaches that retail and other municipal initiatives can use to improve access to food are also named.

How to complement traditional instruments to measure the economic dimension of food security in older people? An application for regions of Argentina.

Introduction: One of the dimensions of food security has to do with economic access to food. Aim: Propose a methodology that allows evaluating economic access to food in Argentina for the elderly population. Methods: Dietary guides for the Argentine population are used. Meanwhile, the food consumption patterns observed in the elderly population in Argentina are considered from a household expenditure survey, from which implicit food prices can also be obtained. Results: Six dietary plans corresponding to different regions of the country are designed and evaluated and it is found that they would be affordable only in two of the six regions analyzed. Conclusion: in the Metropolitan, Pampas, Cuyo, and Northeast regions the cost of the ideal basket is higher than food spending, fundamentally in the Northeast region where food spending should increase by 25%.

A comprehensive analysis of food insecurity in the drought-prone rural areas of Tigray.

BACKGROUND: The number of globally food-insecure people is increasing since 2017. Sub-Saharan Africa has the highest proportion of severely food-insecure people in the world. Tigray region of Ethiopia is one of the food-insecure regions, which, over the past many decades has been affected by recurrent food insecurities. In the drought-prone rural areas of Tigray, many people are living under the condition of chronic hunger. Proper food security studies are vital for proper intervention mechanisms. Yet, previous food security studies have rarely addressed the four pillars of food security: availability, access, utilization, and stability. In this study, all components are duly considered to assess the food insecurity status in the drought-prone rural areas of Tigray, Ethiopia. Of the 34 rural districts in Tigray, 363 households from three drought-prone rural districts were studied. RESULTS: Household Food Insecurity Access Scale and Food Insecurity Experience Scale were adapted to measure the food availability, access to food, and stability components of food security; and, Household Dietary Diversity Score (HDDS), Food Consumption Score (FCS), mid-upper arm circumference, and Bitot's spot were used to analyze the food utilization aspect. Findings show that 68% of the studied community frequently ate less food than they felt they needed and 82.1% of the households have experienced hunger because of lack of food. The study rural districts were unconnected to road networks; hence, 87.9% of the elderly and 20.4% of the women and girls had no access to food markets. Regarding the food utilization, 81.5% of the studied households had poor FCS; and the average HDDS and FCS for the study areas were 2.47 and 18.9, respectively. The prevalence of Global acute malnutrition, severe acute malnutrition (SAM), and moderate acute malnutrition (MAM) for 6-59 months of age children in the study areas were 50.3, 4.2, and 46.1%, respectively. More notably, the prevalence of SAM for children from the food-insecure households was 21.2%. The prevalence of MAM for pregnant and lactating women (PLW) in the study areas was 59.5. Further, the prevalence of Bitot's spot among 6-59 months of age children was 1.9%. On the other hand, all the rural households had anxiety about their future food demands. CONCLUSION: The rural households living in the studied areas were critically food-insecure. All the measurements implied that the food insecurity situation in the study areas was unacceptably worrisome and life-threatening. This calls for an instant action to avert the occurrence of famine and starvation in the drought-prone rural areas of Tigray region. Thus, interventions should primarily target the vulnerable rural people and need to be planned based on attaining food availability first rather than concurrently addressing all components of food security. Further, due emphasis should be given to diversifying livelihood strategies of the vulnerable villagers.

Estrategias de acceso a los alimentos implementadas en Venezuela por un grupo de venezolanos que viven en Cuiabá, Brasil / Food access strategies implemented in Venezuela by a group of Venezuelans living in Cuiabá, Brazil

Resumen La crisis sociopolítica de Venezuela ha generado diversos problemas como la inseguridad alimentaria, la escasez de productos básicos y medicinas, el aumento del desempleo y la migración masiva hacia otros países de la región. Este estudio tuvo por objetivo identificar las estrategias de acceso a los alimentos vividas en Venezuela por los inmigrantes venezolanos que residen en Cuiabá, en Mato Grosso, Brasil. Esta investigación se realizó bajo el enfoque cualitativo para indagar cómo fue el impacto respecto al acceso y consumo de alimentos en Venezuela vivido por los inmigrantes venezolanos desde la documentación, descripción y comprensión de las experiencias que ellos enfrentan. Se incluyeron 13 participantes, la técnica de recolección de datos que se utilizó fueron las entrevistas individuales. Entre los principales hallazgos encontrados se evidenció que la mayoría de los entrevistados no se sentía a gusto con la alimentación que tenía en Venezuela, dadas las pocas condiciones de acceso y disponibilidad de alimentos, muchos de estos manifestaron percepciones de hambre y angustia por la falta de alimentos, y estas situaciones llevaron a buscar mejores condiciones de vida. La crisis en Venezuela que produjo la poca disponibilidad y acceso a los alimentos les generó estrategias para poder garantizar una alimentación permanente dentro de los hogares donde muchas veces estas estrategias no son acordes a una alimentación saludable y adecuada.

Abstract The socio-political crisis in Venezuela has generated various problems, such as food insecurity, shortages of basic products and medicines, increased unemployment and massive migration to other countries in the region. To identify the strategies for access to food experienced by Venezuelan immigrants residing in Cuiabá-MT, Brazil. This research was conducted under the qualitative approach, this approach allowed us to investigate how was the impact regarding the access and consumption of food in Venezuela lived by Venezuelan immigrants residing in Cuiabá - Brazil, from the documentation, description and understanding of the experiences they face; 13 participants were included, the data collection technique used were individual interviews. Among the main findings was that most of the interviewees did not feel comfortable with the food they had in Venezuela, given the poor conditions of access and availability of food, many of them expressed perceptions of hunger and anguish due to the lack of food and these situations led them to seek better living conditions. The socio-political crisis in Venezuela that produced the lack of availability and access to food, generated strategies to ensure a permanent food supply within households where often these strategies are not in line with a healthy and adequate diet.

Association between Fresh Fruit and Vegetable Consumption and Purchasing Behaviors, Food Insecurity Status and Geographic Food Access among a Lower-Income, Racially/Ethnically Diverse Cohort in Central Texas.

The aims of this study were to determine if fresh fruit and vegetable consumption and purchasing behaviors were associated with geographic food access and/or food insecurity status, and to explore the role of sociodemographic characteristics among participants of a lower-income, racially/ethnically diverse cohort. This study used a cross-sectional design and baseline survey data from the FRESH-Austin study (N = 393). Associations between fresh produce consumption/purchasing and food insecurity status and geographic access to food were assessed utilizing univariate, bivariate, and multivariate linear regression methods and potential interactions were examined. The sample 40% reported being food insecure and the majority identified as Hispanic. Geographic food access was directly associated with fresh produce consumption (ß = 0.46, p = 0.02); however, the directionality of the relationship between food insecurity and fresh produce consumption varied due to a significant interaction with race/ethnicity. Only utilizing food assistance was associated with purchasing fewer fresh produce (ß= -1.83, p = 0.03). Findings suggest that communities experience food insecurity and limited healthy food access in different ways, and in some situations, are associated with fresh produce consumption and purchasing behaviors. Future research adopting an intersectionality-sensitive approach to better understand how to best support communities at risk is needed.

Seguridad alimentaria en áreas rurales de la provincia Chimborazo, Ecuador / Food security in rural areas of the Chimborazo province, Ecuador

RESUMEN Introducción: La seguridad alimentaria es un amplio concepto que incluye múltiples factores que de una forma u otra inciden en que la población pueda acceder a una alimentación de calidad. Solo de esta forma se podrá cumplir con la ansiada meta de disponer de una alimentación saludable que no solo permita minimizar la aparición de enfermedades, sino que también contribuya a controlar las ya existentes. Objetivo: Determinar el comportamiento de la seguridad alimentaria en la población rural del cantón Colta, provincia de Chimborazo, Ecuador. Métodos: Investigación básica, de campo, descriptiva y de corte transversal realizada en el cantón Colta, provincia Chimborazo, con una población total de 410 familias dedicadas al cultivo de la quínoa. La muestra quedó conformada por 210 agricultores. Se utilizó la Escala Latinoamericana y Caribeña de Seguridad Alimentaria para determinar la seguridad alimentaria y sus elementos relacionados. Resultados: En el 56,67 % de las familias se identificó inseguridad alimentaria; y fue más significativa en familias con menores de 18 años (66,67 %). Predominó la inseguridad alimentaria ligera (73,95 %). La falta de recursos económicos (86,55 %), el elevado costo de los alimentos (76,49 %), los problemas relacionados con el acceso físico a los alimentos (74,79 %) y la inadecuada cobertura de salud (74,79 %) fueron las determinantes más referidas como causa de inseguridad alimentaria. Conclusiones: El elevado porcentaje de inseguridad alimentaria fue más predominante en las familias con personas menores de 18 años dentro de su composición familiar. Los elementos relacionados con el tema económico fueron los más referenciados como condicionantes de inseguridad alimentaria.

ABSTRACT Introduction: Food security is a broad concept that includes multiple factors that in one way or another affect the population's access to quality food. Only in this way will it be possible to meet the long-awaited goal of having a healthy diet that not only minimizes the appearance of diseases, but also helps to control existing ones. Objective: To determine the behavior of food security in the rural population of the Colta canton, Chimborazo province, Ecuador. Methods: Basic, field, descriptive and cross-sectional research carried out in the Colta canton, Chimborazo province, with a total population of 410 families dedicated to the cultivation of quinoa. The sample was made up of 210 farmers. The Latin American and Caribbean Food Security Scale was used to determine food security and its related elements. Results: In 56.67% of the families food insecurity was identified; being more significant in families with children under 18 years of age (66.67%). Slight food insecurity predominated (73.95%). The lack of economic resources (86.55%), the high cost of food (76.49%), problems related to physical access to food (74.79%) and inadequate health coverage (74, 79%) were the determinants most referred to as a cause of food insecurity. Conclusions: The high percentage of food insecurity was more prevalent in families with people under 18 years of age within their family composition. The elements related to the economic issue were the most referenced as determinants of food insecurity.

Derecho a la alimentación: ¿Qué dicen las constituciones de América y el Caribe?

RESUMEN Introducción: Numerosos países de América y el Caribe cuentan con el derecho constitucional a la Alimentación. Chile no cuenta con este derecho constitucionalizado. Objetivo: Describir comparativamente cómo se encuentra explícito el derecho a la alimentación (DA) en la Constitución de los países de América y el Caribe, generando insumos para aquellos países que no cuentan con este derecho explícito, como en Chile. Fuentes de datos: Esta búsqueda se realizó en las plataformas: Seguridad Alimentaria y Nutricional (SAN-CELAC), Derecho a la Alimentación en el Mundo (FAO) y Constitute Project que presenta las constituciones del mundo. Método de revisión: Se realizó una revisión todas las constituciones disponibles de los países independientes de América y el Caribe y de países con territorios dependientes y departamentos de ultramar en la Región. Posteriormente, en aquellos países que presentan el DA de forma explícita en su texto constitucional, se realizó una revisión sobre las características generales del texto constitucional y de los conceptos asociados a la definición del DA, sugeridos por la FAO. La revisión se llevó a cabo entre los meses de junio y septiembre de 2020. Resultados: Del total de los países revisados (n= 42), solo el 40,5% presentó el DA explícito en su texto constitucional. La seguridad alimentaria es el concepto que aparece con mayor frecuencia. Conclusión: La mayor parte de las constituciones acompañan el DA con características de seguridad alimentaria, disponibilidad y accesibilidad, e incluyen alguna forma de judicialización, conceptos que deberían ser incorporadas la nueva Carta Magna de Chile.

ABSTRACT Introduction: Many American and Caribbean countries consider the right to food as constitutional right. Chile does not have this explicit right in the Constitution. Objective: To describe comparatively how the right to food is explicit in the constitutions of American and Caribbean countries, generating inputs for those countries that do not have this constitutional right, such as the case of Chile. Data sources: This research was carried out on platforms: Food and Nutritional Security (SAN-CELAC), Right to Food in the World (FAO) and Constitute Project which presents constitutions of the world. Revision method: A revision was made of all available constitutions of American and independent Caribbean countries, dependent territories and overseas departments in the Region. Subsequently, in those countries which explicitly consider the right to food in constitutional texts, a review of general characteristics and right to food-associated concepts, suggested by FAO, was carried out. The review was carried out between June and September 2020. Results: Of the total of countries reviewed (n= 42), 40.5% presented the right to food in constitutional text. The most frequently associated concept was food security. Conclusion: Most of the revised constitutions accompany the right to food with food safety, availability and accessibility characteristics, and include kinds of judicialization, concepts that should be incorporated into the new Magna Carta of Chile.

The Economic Perspective of Food Poverty and (In)security: An Analytical Approach to Measuring and Estimation in Italy.

The UN Sustainable Development Goals have set clear targets on global poverty, hunger and malnutrition to be achieved by 2030, which have prompted academics and policymakers to identify useful strategies and drivers. Moreover, the COVID19 pandemic has exacerbated inequalities at national and sub-national levels thus hampering the achievement of these goals. On considering the multifaceted nature of poverty, a recent research strand focuses on food poverty and insecurity issues in terms of economic access to food and healthy diet consumption, with moderate and extreme food insecurity affecting almost 9% of the population in Europe and North America. This paper aims to analyse food poverty and insecurity at regional level in Italy. Using micro-data from the Italian Household Budget Survey carried out by ISTAT, an analytical approach was proposed to define and measure the different degree of food poverty and insecurity. Moreover, to obtain insights into whether food poverty and insecurity can afford population healthy nutrition, inequality of the distributions of food expenditure categories are estimated. The results provided us with information on other important aspects of the poverty. Indeed, in Italy individuals who are at-risk-of-food-poverty or food insecure amount to 22.3% of the entire population. Furthermore, the at-risk-of-food-poverty-rate varies at regional level from 14.6% (Umbria) to 29.6% (Abruzzo), with high levels of food consumption inequalities observed above all for vegetables, meat and fish. All these issues could help policy makers to define economic intervention policies aimed at reducing social exclusion and achieving more equitable and sustainable living conditions for the entire population.

Intra-specific Variation in the Social Behavior of Barbary macaques (Macaca sylvanus).

Non-human primates show an impressive behavioral diversity, both across and within species. However, the factors explaining intra-specific behavioral variation across groups and individuals are yet understudied. Here, we aimed to assess how group size and living conditions (i.e., captive, semi-free-ranging, wild) are linked to behavioral variation in 5 groups of Barbary macaques (N=137 individuals). In each group, we collected observational data on the time individuals spent in social interactions and on the group dominance style, along with experimental data on social tolerance over food and neophobia. Our results showed that differences in group size predicted differences in the time spent in social interactions, with smaller groups spending a higher proportion of time in close spatial proximity, but a lower proportion of time grooming. Moreover, group size predicted variation in dominance style, with smaller groups being more despotic. Social tolerance was affected by both group size and living conditions, being higher in smaller groups and in groups living in less natural conditions. Finally, individual characteristics also explained variation in social tolerance and neophobia, with socially integrated individuals having higher access to food sources, and higher-ranking ones being more neophobic. Overall, our results support the view that intra-specific variation is a crucial aspect in primate social behavior and call for more comparative studies to better understand the sources of within-species variation.

The HOME Study: Understanding How College Students at a Hispanic Serving Institution Coped with Food Insecurity in a Pandemic.

College students represent a unique population of adults, who may be more likely to experience food insecurity due to their transient circumstances, limited access to resources, and increased educational expenses. But little is known about how college students and their households mitigate food insecurity, particularly during a crisis like the COVID-19 pandemic. The Household Observations of Meals and Environments (HOME) Study described how college students in the US utilized multilevel resources, including an on-campus food pantry, to maintain food security during the pandemic. A convenience sample of college students (n = 18) were recruited from an on-campus food pantry and provided quantitative and qualitative data through online surveys and in-depth Zoom interviews. Survey data were analyzed to describe sociodemographic characteristics. In-depth interviews were recorded, transcribed, coded, and analyzed thematically to identify emergent themes. Social support and the use of an on-campus food pantry were primary factors in maintaining a food security safety net. Students faced barriers when trying to access federal and state food assistance programs and identified multilevel resources, their food security, and the role of social support as facilitators in their perceptions of food insecurity status and experiences. Findings highlight practical implications for research related to on-campus food insecurity interventions and policies to support food security among college students.

Identifying Food Deserts and People with Low Food Access, and Disparities in Dietary Habits and Health in Korea.

This study aims to identify the regions and people with low food access (LFA) for Korea at the national level and to examine disparities in food consumption, dietary behavior, and health outcome for those regions and people. Based on the distance to the nearest grocery store from residence, the regions and people with LFA are identified through geographical information system (GIS) analysis. To examine disparities between the regions and people with LFA and without LFA, a consumer survey is conducted and data from National Health and Nutrition Examination Survey and Community Health Survey are analyzed. This study found that there exists a serious access to food issue in Korea, especially for the aged. Moreover, there also exist significant disparities between the regions and people with and without LFA in the distance and one-way travel time to the grocery store that is mainly visited, frequency of offline/online grocery shopping, availability of various foods, dietary habits such as eating regularly, eating nutritionally balanced foods, and eating sufficient fruit/vegetable/whole grains, the acquisition and utilization of food-related information, and health outcomes. This study suggests that, to resolve such a serious food access problem, assistance policies, such as mobile grocery stores and lunch-box delivery, need to be activated in countries similar to Korea since this problem could potentially deteriorate the national medical finances as well as the regional and individual disparities.

Asociación de las determinantes de la seguridad alimentaria nutricional con la presencia de sobrepeso y obesidad en la población que acude a la unidad de epidemiología clínica del IINSAD de la Facultad de Medicina ­ UMSA / Association of the determinants of nutritional food safety with the presence of overweight and obesity in the population that comes to the clinical epidemiology unit of the IINSAD of the Faculty of Medicine - UMSA

OBJETIVO: identificar la asociación de las determinantes de la seguridad alimentaria con el sobrepeso y obesidad de la población que acude a la Unidad de Epidemiología Clínica del IINSAD de la Facultad de Medicina, Enfermería, Nutrición y Tecnología Médica ­ UMSA. MATERIAL Y MÉTODO: estudio de Casos y Controles, desarrollado en la Unidad de Epidemiologia Clínica del IINSAD de la Facultad de Medicina, UMSA. Ingresaron al estudio 288 personas, 144 casos y 144 controles, se aplicó la encuesta alimentaria, identificando el consumo y la frecuencia de alimentos y preguntas específicas sobre disponibilidad, acceso físico y económico a los alimentos. Se realizó una evaluación antropométrica para identificar los casos y controles. RESULTADOS: existe una probabilidad mayor de presentar sobrepeso u obesidad en la población con insuficiente acceso económico a los alimentos OR= 2.1 (IC95% 1.3-3.6 p=0.003). A mayor proporción de gasto en alimentos de una familia, mayor es el consumo de energía provenientes de carbohidratos y grasas OR= 30 (IC95% 23.6-58.8) p=0.000. No se encontró asociación entre la disponibilidad de alimentos y el lugar de aprovisionamiento. CONCLUSIONES: son factores asociados para la presencia de sobrepeso y obesidad los determinantes de seguridad alimentaria nutricional como ingreso destinado a la compra de los alimentos, el consumo alimentario en cantidad y calidad de la dieta consumida y adecuación de nutrientes, la disponibilidad de alimentos y el lugar de aprovisionamiento no presenta asociación

OBJECTIVE: to identify the association of food security determinants of overweight and obesity in the population attending the Clinical Epidemiology Unit of IINSAD Faculty of Medicine, Nursing, Nutrition and Medical Technology - UMSA La Paz, 2015. MATERIAL AND METHODS: an observational analytical case-control study, 288 individuals attending the IINSAD of the Faculty of Medicine, Nursing, Nutrition and Medical Technology - UMSA. 144 cases and 144 controls were analyzed. A food survey, where the consumption and food frequency and specific questions about availability, physical and economic access to food occurred was applied. Anthropometric assessment was performed to identify cases and controls. RESULTS: there is a greater likelihood of becoming overweight or obese in people with insufficient economic access to food OR = 2.1 (95% CI 1.3-3.6 p = 0.003). The greater the food expenditure proportion of a family, the greater is the consumption the energy from carbohydrates and fats OR = 30 (95% CI 23.6-58.8 p = 0.000). No association between the availability of food and the place of supply is found. CONCLUSIONS: there are factors associated to the presence of overweight and obesity determinants of nutritional food security such as income for the purchase of food, food consumption in quantity and quality of consumed diet and nutrient adequacy, the availability of food and the place of supplying is not considered associated for this study

Social Assistance Payments and Food Insecurity inAustralia: Evidence from the HouseholdExpenditure Survey.

It is widely understood that households with low economic resources and poor labourmarket attachment are at considerable risk of food insecurity in Australia. However, little is knownabout variations in food insecurity by receipt of specific classes of social assistance payments thatare made through the social security system. Using newly released data from the 2016 HouseholdExpenditure Survey, this paper reports on variations in food insecurity prevalence across a range ofpayment types. We further investigated measures of financial wellbeing reported by food-insecurehouseholds in receipt of social assistance payments. Results showed that individuals in receiptof Newstart allowance (11%), Austudy/Abstudy (14%), the Disability Support Pension (12%),the Carer Payment (11%) and the Parenting Payment (9%) were at significantly higher risk of foodinsecurity compared to those in receipt of the Age Pension (<1%) or no payment at all (1.3%). Resultsfurther indicated that food-insecure households in receipt of social assistance payments enduredsignificant financial stress, with a large proportion co-currently experiencing "fuel" or "energy"poverty. Our results support calls by a range of Australian non-government organisations, politicians,and academics for a comprehensive review of the Australian social security system.

The Association between Stressful Events and Food Insecurity: Cross-Sectional Evidence from Australia.

A considerable body of empirical evidence exists on the demographic and socio-economic correlates of food insecurity in Australia. An important omission from recent studies, however, is an understanding of the role of stressful life events, or stressors in explaining exposure to food insecurity. Using nationally representative data from the 2014 General Social Survey and multivariable logistic regression, this paper reports on the association between 18 discrete stressors and the likelihood of reporting food insecurity in Australia. The results, adjusted for known correlates of food insecurity and complex survey design, show that exposure to stressors significantly increased the likelihood of experiencing food insecurity. Importantly, stressors related to employment and health approximately doubled the odds of experiencing food insecurity. The results underscore the complex correlates of food insecurity and indicates that conceptually it interacts with many important social and economic problems in contemporary Australia. There is no simple fix to food insecurity and solutions require co-ordination across a range of social and economic policies.

Factors influencing the priority of access to food and their effects on the carcass traits for Japanese Black (Wagyu) cattle.

The factors influencing the priority of access to food and the effects of the priority of access to food on their carcass traits were analyzed for Japanese Black (Wagyu) cattle in a semi-intensive fattening production system. The records of 96 clinically healthy steers and heifers were analyzed. The calves at ∼3 to 4 months of age were allocated to pens with four animals per pen; all four animals in the same pen were of the same sex and of similar body size. The ranking of the animals' priority of access to food (1st, 2nd, 3rd and 4th), which was determined by the farm manager, was used as an indicator of social dominance in the present study. Four models including sire line, maternal grandsire line and the difference in the animals' birth dates as fixed effects were used to analyze factors influencing the priority of access to food. Ranking was represented by ordinal scores (highest=4, lowest=1) in Model 1, and the binary scores were assigned in Model 2 (highest=1; 2nd, 3rd and 4th=0), Model 3 (1st and 2nd=1; 3rd and 4th=0) and Model 4 (1st, 2nd and 3rd=1; lowest=0). The results showed that the difference in the animals' birth dates had a significant effect on the establishment of the priority of access to food in Model 3 (P<0.05), suggesting that animals born earlier may become more dominant in the pen. The maternal grandsire line tended to affect the social rank score in Models 2 and 3 (P<0.10). Our results indicated that the maternal grandsire line may affect the temperament of calves through their mothers' genetic performance and thereby more aggressive calves may be more dominant and have higher priority of access to food. On the other hand, there was a significant effect of the priority of access to food on beef marbling score (BMS; P<0.05), and the priority of access to food also tended to influence the carcass weight (P=0.09). The highest BMS was observed for animals with the first rank of the priority of access to food (P<0.05), and the higher-ranking animals had the tendency to be heavier carcass than the lower-ranking animals. Our findings emphasized the importance of information about the priority of access to food determined by farmers' own observation on implementing best management practices in small-scaled semi-intensive beef cattle production systems.

Factores relacionados con la composición de la canasta básica de alimentos de las familias en la ciudad de La Paz, gestión 2012 / Factors related to the composition of a basic food basket of families in the city of La Paz, term 2012

OBJETIVO: determinar los factores relacionados con la composición de la canasta básica de alimentos de las familias en la ciudad de La Paz. MATERIAL Y MÉTODO: es un estudio analítico transversal, en 422 familias de la ciudad de La Paz, de los 7 Macrodistritos; Cotahuma, Max Paredes, Periférica, Centro, San Antonio, Sur y Mallasa. Se aplicó una encuesta con variables socioeconómicas (Método Graffar - Méndez Castellanos), Se registró los hábitos alimentarios (cantidad, calidad, armonía y adecuación de la dieta consumida), el acceso físico y económico a los alimentos (porcentaje de ingreso familiar destinado a la compra de los alimentos). RESULTADOS: la composición de la canasta básica de alimentos en cantidad y calidad guarda relación con factores socioeconómicos, hábitos alimentarios y el acceso físico a los alimentos. (p<0,05). Las familias compuestas por 3,5 a 4,4 miembros requieren de 2.5 a 3.5 salarios básicos, solo para cubrir el gasto en alimentación. El porcentaje de ingreso familiar destinado a la alimentación es alrededor del 40%. Las familias con menos ingresos destinan mayor porcentaje de sus ingresos a la alimentación y las familias con más ingresos destinan un menor porcentaje de sus ingresos en alimentación. CONCLUSIONES: la capacidad de compra de las familias es limitada para alcanzar una adecuada canasta alimentaria básica y está relacionado principalmente con el nivel socioeconómico, el acceso físico y económico de los alimentos y los hábitos alimentarios. Si bien el salario básico en los últimos años se incrementó, priman otros factores que determinan la composición de una Canasta Básica Alimentaria.

OBJECTIVE: to determine factors related to the composition of the nutritious food basket of families living in the city of La Paz. MATERIAL AND METHOD: this is a transversal analytical study of 422 families in the city of La Paz, of the 7 Macrodistricts: Cotahuma, Max Paredes, Periférica, Centro, San Antonio, Sur and Mallasa. A survey with socioeconomic variables (Graffar-Mendez Castellanos Method) was applied. Food habits and consumption were registered (in order to determine the quantity, quality, harmony and adaptation of the consumed diet), the physical and economic access to food (in order to determine the percent of the family's income allotted to the purchase of food). RESULTS: It can be asserted that the composition of the family's cost of the basic nutritious food basket, in quantity and quality keeps a relationship with socioeconomic factors, food habits and physical access to food with less than 5 percent significance. (p<0,05). Urban families of La Paz made up of 3,5 to 4,4 members require at least 2.5 to 3.5 minimum wages only in order to cover food expenditures. The family income percent allotted to food is around 40%. Families with lesser incomes allot a higher income percent to food and families with higher incomes allot a lesser income percent to food. CONCLUSIONS: purchase capacity of families in order to reach an adequate basic nutritious food basket is limited and it is mainly related to the socioeconomic level, the family's physical and economic access. Although minimum wages have been increased over the pastyears, there are various already mentioned factors determining the composition of a family's basic nutritious food basket.
