          Abstract

          El objetivo del presente trabajo es determinar posibles predictores de la diversidad alimentaria en hogares vinculados a guarderías infantiles en zonas pobres de cinco regiones de Venezuela. La diversidad alimentaria se refiere al número de alimentos primarios diferentes disponibles en el hogar en un periodo determinado. Se estudió 464 hogares seleccionados en 232 guarderías infantiles de cinco regiones venezolanas. La diversidad alimentaria se estimó por el método de registro de las disponibilidades alimentarias en el hogar. En promedio, la diversidad alimentaria fue 26 ±9, aunque variaba significativamente por región (p£0,001). Las variables gasto mensual en alimentos per cápita, años de estudio de la mujer, nivel de Seguridad Alimentaria en el Hogar y tamaño del hogar predicen 20% de la variación de la diversidad alimentaria del hogar. En esta muestra los hogares con mayor diversidad alimentaria se caracterizan por destinar más recursos a la alimentación, poseer madres con mayor nivel educativo, ser hogares clasificados como "seguros" según la escala de Seguridad Alimentaria en el Hogar y tener mayor número de miembros. Conocer estos factores contribuye a comprender aspectos de los hogares relacionados con el comportamiento de la demanda de alimentos y la calidad de la dieta.

          The purpose of this study is to determine possible predictors of household food diversity among beneficiaries of government subsidized day care centers in poor communities located in five regions of Venezuela. Food diversity score is the number of primary foods available to the household during a specified period. Four hundred sixty four households were selected from 232 centers located in the five regions. The list-recall method was used to estimate household food diversity. On average, household food diversity score was 26 ±9 but highly variable among regions (p£0.001). Food cost per month, female schooling, household food security level and household size predicts 20% of variation of the variable food diversity score. In this study, greater food diversity is associated with households that spend more money on food, better educated householders, more food-secure households and more numerous family members. Knowledge of these factors contributes to a better understanding of household food demand determinants and aspects of behavior within the home that may be associated with food quality.

          O objetivo do presente trabalho é determinar possíveis preditores da diversidade alimentária em lares vinculados a creches infantis em zonas pobres de cinco regiões da Venezuela. A diversidade alimentária se refere ao número de alimentos primários diferentes disponíveis no lar em um período determinado. Estudou-se 464 lares selecionados em 232 creches infantis de cinco regiões venezuelanas. A diversidade alimentária se estimou pelo método de registro das disponibilidades alimentárias no lar. Em média, o índice de diversidade alimentaria foi 26 ±9, embora variava significativamente por região (pd"0,001). As variáveis gasto mensal em alimentos per capita, anos de estudo da mulher, nível de Segurança Alimentária e tamanho do lar predizem 20% da variação da diversidade alimentaria deste. Nesta amostra os lares com maior diversidade alimentaria se caracterizam por destinar mais recursos à alimentação, possuir mães com maior nível educativo, ser lares classificados como "seguros" segundo a escala de Segurança Alimentária no lar e ter maior número de membros. Conhecer estes fatores contribui a compreender aspectos dos lares relacionados com o comportamento da demanda de alimentos e a qualidade da dieta.

            A prospective study of diet quality and mortality in women.

            Most studies of diet and health care have focused on the role of single nutrients, foods, or food groups in disease prevention or promotion. Few studies have addressed the health effects of dietary patterns, which include complex mixtures of foods containing multiple nutrients and nonnutrients. To examine the association of mortality with a multifactorial diet quality index. Data from phase 2 (1987-1989) of a prospective cohort study of breast cancer screening, the Breast Cancer Detection Demonstration Project, with a median follow-up of 5.6 years. A total of 42,254 women (mean age, 61.1 years) who completed the food frequency questionnaire portion of the survey. All-cause mortality by quartile of Recommended Food Score (RFS; the sum of the number of foods recommended by current dietary guidelines [fruits, vegetables, whole grains, low-fat dairy, and lean meats and poultry] that were reported on the questionnaire to be consumed at least once a week, for a maximum score of 23). There were 2065 deaths due to all causes in the cohort. The RFS was inversely associated with all-cause mortality. Compared with those in the lowest quartile, subjects in the upper quartiles of the RFS had relative risks for all-cause mortality of 0.82 (95% confidence interval [CI], 0.73-0.92) for quartile 2, 0.71 (95% CI, 0.62-0.81) for quartile 3, and 0.69 (95% CI, 0.61-0.78) for quartile 4 adjusted for education, ethnicity, age, body mass index, smoking status, alcohol use, level of physical activity, menopausal hormone use, and history of disease (chi2 for trend = 35.64, P<.001 for trend). These data suggest that a dietary pattern characterized by consumption of foods recommended in current dietary guidelines is associated with decreased risk of mortality in women.

              Dietary diversity and subsequent mortality in the First National Health and Nutrition Examination Survey Epidemiologic Follow-up Study.

              We examined the relation of dietary diversity to subsequent all-cause mortality by using data from the First National Health and Nutrition Examination Survey (NHANES I) Epidemiologic Follow-up Study, 1982-1987. The analytic cohort consisted of 4160 men and 6264 women (including 2556 deaths), 25-74 y at baseline (1971-1975). Twenty-four-hour dietary recalls were evaluated for variety among the five major food groups: dairy, meat, grain, fruit, and vegetable, with a dietary diversity score (DDS); consumption of each food group contributed 1 point to a maximum possible DDS of 5. Age-adjusted risk of mortality was inversely related to DDS (P < or = 0.0009) in men and women. The inverse diversity-mortality association was adjusted for potential confounders: education, race, smoking status, and dietary fiber intake; the relative risk of mortality in men and women consuming two or fewer food groups was 1.5 (95% CI 1.2-1.8) and 1.4 (95% CI 1.1-1.9), respectively. In conclusion, diets that omitted several food groups were associated with an increased risk of mortality.
