Factors associated with food insecurity in older adults in Ecuador

ABSTRACT The objective was to determine the relationship between various factors and food insecurity, using a cross-sectional analytical study of 400 older adults living in rural and urban areas of the Azuay province in Southern Ecuador. Food security was measured using the Latin American and Caribbean Food Security Scale (ELCSA). The data was analyzed using version 15 of the Statistical Package for the Social Sciences (SPSS) program, and the odds ratio with 95% confidence interval (CI) was used to determine statistical association. The incidence of food insecurity was higher in older adults who live in households comprised only of members above the age of 18 (43.7%) and in rural zones (65%). Food insecurity is high in older adults, especially in individuals who live in rural areas and who have low levels of education and low socioeconomic levels. It is necessary to implement public policy and preventative strategies to mitigate the risk of food insecurity in older adults.

RESUMEN El objetivo fue determinar la relación entre diversos factores y la inseguridad alimentaria, con un estudio analítico transversal en 400 adultos mayores que viven en zonas rurales y urbanas de la provincia de Azuay en el sur de Ecuador. La seguridad alimentaria se midió utilizando la Escala de Seguridad Alimentaria de América Latina y el Caribe (ELCSA). Los datos fueron analizados en la versión 15 del programa Statistical Package for the Social Sciences (SPSS), y se utilizó el Odds Ratio con IC 95% para determinar la asociación estadística. La incidencia de la inseguridad alimentaria fue mayor en los adultos mayores que viven en hogares compuestos únicamente por miembros mayores de 18 años (43,7%) y en las zonas rurales (65%). La inseguridad alimentaria es alta en los adultos mayores, especialmente en individuos que viven en zonas rurales y que tienen bajos niveles educativos y niveles socioeconómicos bajos. Es necesario implementar políticas públicas y estrategias preventivas para mitigar el riesgo de inseguridad alimentaria en los adultos mayores.

Asociación del nivel socioeconómico y educacional en los egresos por cáncer de mama en Chile durante los años 2001 al 2016 / Association of the socioeconomic and educational level in the breast cancer hospital outbreaks in Chile during the years 2001 to 2016

Introducción: El cáncer de mama constituye la primera causa de muerte en los cánceres en Chile según Globocan 2018. Dentro de los factores que explican esta alta mortalidad encontramos una baja tasa de detección y de realización de mamografías en los niveles socioeconómicos altos. Es por esto que comprender las causas de defunción y los factores que afectan en la mortalidad y letalidad por cáncer de mama en los últimos 17 años nos permitirá enfocar las políticas públicas de los próximos 50 años. Los objetivos generales de este trabajo fueron caracterizar los egresos hospitalarios en los pacientes por cáncer de mama según la edad, el sexo, la previsión, el nivel socioeconómico y educacional en Chile durante los años 2001 al 2016 y calcular la mortalidad y letalidad específica en estas mismas variables durante los años 2001 a 2016. El objetivo específico es asociar las variables socioeconómicas y educacionales, estimando los Odd's ratios de las variables en los egresos hospitalarios por cáncer de mama en Chile durante los años 2001 al 2016. Materiales y Métodos: Estudio de cohorte longitudinal retrospectivo en 81,072 egresos hospitalarios y 20,220 defunciones obtenidas de la página DEIS MINSAL, años 2001-2016. Para el análisis univariado se efectuó una regresión de ajuste de tasas Prais-weinstein según edad y sexo según modelo OMS de ajuste de tasas. Para las variables de tipo discreta se describieron mediante porcentajes y tasas y para las variables de tipo continua se utilizó mediana y desviación estándar. Se efectuó un test de smirnov-kolmolgorov para determinar el tipo de distribución y de normalidad de las muestras. Para las variables de tipo dicotómica se utilizó un modelo de regresión logística binaria para describir estas variables y determinar la posible asociación entre el nivel socioeconómico y educacional de las pacientes diagnosticadas por cáncer de mama. Resultados: Murieron 1,88 veces más personas de nivel socioeconómico alto con un IC entre 1,83- 1,94 con respecto a la población de nivel socioeconómico bajo. En cambio, las personas con un mayor nivel educacional murieron 0,5 veces menos según la regresión realizada respecto al bajo nivel educacional con un IC entre 0,47- 0,52, pero a menor nivel educacional aumentó 20 veces la mortalidad, constituyendo una causa inversa. Respecto al sexo las mujeres murieron 2,08 veces más que los hombres. Para el nivel socioeconómico alto en relación al bajo un OR [1.88 (1.83 a 1,94)], p<0,0001], para el nivel educacional alto en relación al bajo fue a favor del mayor nivel educacional con OR [0,5 (0,47 - 0,52)] y en cuanto a la comparación de sexos un OR [1,04 (1,03-2,17), p=0,039]. Es decir, la diferencia entre mortalidad que hubo fue significativa para todos los intervalos tanto para sexo, nivel educacional como para nivel socioeconómico. Se encontró una constante de 0,013 de mortalidad basal, es decir, todos tienen 1,3% de riesgo de morir por cáncer de mama independiente del nivel socioeconómico, educacional y del sexo. Conclusión: Existen diferencias estadísticamente significativas respecto a la mortalidad entre los niveles socioeconómicos altos y bajos y también en nivel educacional, sin embargo, al realizar los métodos de regresión se obtuvo una mayor mortalidad y mayor riesgo de morir por cáncer de mama en los niveles socioeconómicos más altos asociados a, probablemente, la menor cantidad de tamizajes y realización de mamografías en este estrato. A partir del año 2008 se observó un incremento a los niveles originales observados al inicio del segundo milenio incrementando las diferencias existentes en los índices de desigualdad tanto por nivel educacional como por nivel socioeconómico incrementando en 20 veces respecto al nivel educacional, y 1.88 respecto al nivel socioeconómico.

Introduction: Breast cancer is the leading cause of death in cancers in Chile according to Globocan 2018. Among the factors that explain this high mortality, we find a low rate of detection and performance of mammograms in high socioeconomic levels. This is why understanding the causes of death and the factors that affect mortality and fatality from breast cancer in the last 17 years will allow us to focus on public policies for the next 50 years Materials and Methods: Retrospective longitudinal cohort study in 79,996 hospital discharges and 20,220 deaths obtained from the DEIS MINSAL page, years 2001 -2016. For the univariate analysis, a Prais-Weinstein rate adjustment regression was performed according to age and sex according to the WHO rate adjustment model. For discrete type variables, they were described by percentages and rates, and median and standard deviation were used for continuous type variables. A smirnov-kolmolgorov test was performed to determine the type of distribution and normality of the samples. For dichotomous variables, a binary logistic regression model was used to describe these variables and determine the possible association between the socioeconomic and educational level of the patients diagnosed with breast cancer. Abstract: In this observational, longitudinal and retrospective study with 101.292 patients that includes men and women of all ages with diagnosis of breast cancer all along Chile, we´ll analyze the impact of socioeconomic level, evaluated through educational level and money income, into the prevalence, mortality and lethality of breast cancer in the years 2001 to 2016. Results: People with a high socioeconomic level died 1.88 times more, with a CI between 1.83 and 1.94, than those with a low socioeconomic level. On the other hand, people with a higher educational level died 0.5 times less according to the regression carried out with respect to the low educational level with a CI between 0.47 and 0.52, but the lower the educational level the mortality increased 20 times, constituting an inverse cause. Regarding sex, women died 2.08 times more than men. For the high socioeconomic level in relation to the low one an OR [1.88 (1.83 to 1.94)], p<0.0001], for the high educational level in relation to the low one it was in favor of the higher educational level with OR [0.5 (0.47 - 0.52)] and as for the comparison of sexes an OR [1.04 (1.03-2.17), p=0.039]. In other words, the difference between mortality was significant for all the intervals for sex, educational level and socioeconomic level. A constant baseline mortality of 0.013 was found, i.e., everyone has a 1.3% risk of dying from breast cancer regardless of socioeconomic level, educational level and sex. Conclusions: There are statistically significant differences in mortality between high and low socioeconomic levels and also in educational level; however, when regression methods were used, a higher mortality and higher risk of dying from breast cancer was obtained in the higher socioeconomic levels, probably associated with the lower number of screenings and mammograms performed in this stratum. As of 2008, an increase to the original levels observed at the beginning of the second millennium was observed, increasing the existing differences in the inequality indexes both by educational level and socioeconomic level, increasing by 20 times with respect to educational level, and 1.88 times with respect to socioeconomic level.

Changes in children's lung function over two decades in relation to socioeconomic, parental and household factors in Wuhan, China.

BACKGROUND: It is important to identify risk and beneficial factors for children's lung function. This study aims to ascertain potential changes in children's lung function in relation to changes in socioeconomic, parental and household factors, based on a comparison between two periods spanning 25 years in Wuhan, the largest metropolis in central China. METHODS: In two cross-sectional studies, lung function measurements and questionnaire surveys were conducted on school-age children in 1993-1996 (Period I) and in 2018 (Period II). Children of 6-12 years old from elementary schools were selected by a multistage sampling method. Demographic information, socioeconomic status, feeding methods, parental illness and behavior patterns, as well as household characteristics, were collected through a questionnaire survey. Spirometric lung function was measured, including forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), forced expiratory flow at 25% and 75% of the pulmonary volume (FEF25-75), and peak expiratory flow (PEF). Wilcoxon analysis of variances was used to assess the differences in lung function indexes between Period I and Period II. Multiple linear regression models were used to estimate the association of lung function with regard to socioeconomic, parental and household factors, respectively. RESULTS: Significant prevalence reductions were observed for household coal use, paternal smoking and maternal asthma, while the prevalence increased significantly for children sleeping in their own rooms or own beds and breastfeeding, ventilation use during cooking, and parental education level from Period I to Period II. When adjusted for age, height, weight, sex and other factors assessed in the study, children had significant lower values of FVC, FEV1, and PEF in Period II than in Period I. Enclosed kitchen was significantly associated with lower lung function in children in Period I. Urban living condition and higher maternal education level were each associated with a higher FVC, while father having no fixed income was associated with a lower FVC and a lower FEV1, respectively, in Period II. In comparison with Period I, the beneficial impact of urban living and that of breastfeeding were enhanced and the detrimental effect of poor household condition was weakened in Period II. CONCLUSIONS: Lung function was lower in 2018 than in 1993-1996 in school-age children living in Wuhan. Although improvements in urban living and household environmental conditions as well as increased breastfeeding in Period II could have contributed to increased lung function, other unmeasured risk factors may have played a more dominant role in leading to a net decrease in lung function from Period I to Period II. Future studies are needed to identify these risk factors.

Changes in children's asthma prevalence over two decades in Lanzhou: effects of socioeconomic, parental and household factors.

BACKGROUND: The prevalence of childhood asthma may have changed with rapid economic development. This study aims to ascertain potential changes in asthma prevalence in relation to changes in socioeconomic, parental and household factors, based on a comparison between two periods spanning over 20 years in Lanzhou, a large northwestern city of China. METHODS: Cross-sectional studies using the same protocols were performed in Lanzhou, China in 1994-1995 (Period I) and in 2017 (Period II). Children of 6-12 years old from elementary schools were selected by a multistage sampling method. Information on the presence of asthma and asthma-related symptoms of children, socioeconomic status, feeding methods, parental illness and behavior patterns, as well as household characteristics, were collected through a questionnaire survey. Logistic regression models were used to estimate odds ratios of asthma prevalence with regard to socioeconomic, parental and household factors, respectively. RESULTS: Significant prevalence reductions were observed for paternal smoking, household coal use, and parental asthma, while the prevalence increased significantly for children sleeping in their own rooms or own beds, ventilation use during cooking, and parental occupation and education level after 22 years. In children, the prevalence of ever-diagnosed asthma decreased from 3.2% in period I to 1.5% in Period II (P<0.001); the prevalence of wheeze also decreased from 15.4% to 9.3% (P<0.001). Passive smoking (OR =1.531, 95% CI: 1.032-2.270) and poor household ventilation (OR =1.709, 95% CI: 1.208-2.416) were significantly associated with an increased prevalence of wheeze in Period I, whereas household mold (OR =2.112, 95% CI: 1.203-3.811) was significantly associated with prevalence of wheeze. Parental asthma history was associated with increased prevalence of asthma and asthma-related symptoms. Breastfeeding was significantly associated with reduced risk of asthma in period II children. CONCLUSIONS: The prevalence of asthma and that of asthma-related symptoms were lower in 2017 than in 1994-1995 in school children living in Lanzhou. In 2017 with increased urbanization and industrialization, breastfeeding became a significant protective factor and household mold was a significant risk factor for asthma diagnosis and asthma-related symptoms. Promoting breastfeeding and household mold control is recommended to reduce the risk of childhood asthma in contemporary Lanzhou.

The Correlation between the Family Levels of Socioeconomic Status and Stage at Diagnosis of Breast Cancer.

BACKGROUND: Stage is one of the most important prognostic factors for the cancer diagnosis, including the breast cancer. Studies have found that the rate of breast cancer late-stage diagnosis, among the women with lower socioeconomic status, is more than the others. The aim of this study was investigation the relationship between family levels of socioeconomic status and stage at diagnosis of breast cancer. METHODS: This cross-sectional, descriptive study has conducted on 526 patients who have suffered from breast cancer, and have registered in Cancer Research Center of Shahid Beheshti university of Medical science, from March 2008 till December 2013. A reliable and valid questionnaire about family status of socioeconomic status, have filled by interviewing the patients via phone. For analyzing the data, Multinomial logistic regression, Kendal tau-b correlation coefficient and Contingency Coefficient tests have executed by SPSS 19. RESULTS: The results have indicated that the mean age of the patients was 48.30 (SD=11.41). There was a significant relationship between stage at diagnosis of breast cancer and family levels of socioeconomic status at the time of diagnosis (p=0.024). Also, the relationship between stage at diagnosis and living place (in or out of Tehran) was significant (p=0.044). In the Multiple logistic regressions, these associations were significant. There wasn't any significant relationship between stage of diagnosis of breast cancer and age, marital status and family history. CONCLUSION: Regarding the results of this study, deep paying attention to the family socioeconomic status as an important variable in stage at diagnosis of breast cancer, among Iranian women, was too important, and then providing the prevention plans related to this topic has seemed necessary.

Resultados y Conclusiones: La anemia presento diferencias (p<0.05) entre los niveles soci21es, la depleción fue 42 % en la población total. El desarrollo motor fue homogéneo en los grupos sociales; mientras que el mental presento diferencias ( p< 0.05) en retraso leve y significativo, siendo los mas afectados los niños del nivel bajo. En desarrollo y parámetros bioquímicos, el 19 % de los niños con anemia y depleción, presentaron retraso motor leve, mientras que en desarrollo mental, el retraso leve y significativo afecto en doble proporción a los niños con depleción y anemia en comparación con los niños normales.

Aims: To correlate the iron biochemical screening with cognitive and motor development, related to social background, in 6 to 24 month infants. Methods: a population - based study of 276 children. The iron deficiency was determine by the modified criterion of Hillman ( 1996), combining three different screenings tests: serum ferritin, hemoglobin and erythrocyte protoporphyrin. To analyse development we used Bayley 11 Scale. Results and conclusions: the anaemia was significative different (p< 0,05) between social levels, 36% in children with low socioeconomic background, 8% for the high one and iron deficiency without anaemia 42% in the total population. The motor development was homogeneous by social groups, showed 1 % significative delay, 8% light delay. But the mental development shows significative differences (p<0,05) in both light and significative delay, been the must affected children with low socioeconomic background.
