Intake and food sources of macronutrients among older Hispanic adults: association with ethnicity, acculturation, and length of residence in the United States.

摘要

OBJECTIVE: To describe the food intake and food sources of macronutrients in diets of older Hispanic adults in the Northeastern United States and to explore relationships between acculturation, years in the United States, and macronutrient intake. DESIGN: Cross-sectional study using a representative sample of older Hispanic adults and a comparison group of non-Hispanic whites. SUBJECTS/SETTING: Hispanic (n = 711) and non-Hispanic white (n = 226) persons, aged 60 years and older, residing in Massachusetts. STATISTICAL ANALYSIS: Macronutrient intakes, collected by 24-hour dietary recall, were compared across ethnic groups by means of the general linear models procedure (with Bonferroni adjustments). Associations between macronutrient intake and predictor variables were tested with Pearson correlations and linear regression. The contribution of foods to total intake of macronutrients was determined by use of a rank procedure. RESULTS: Hispanic elderly subjects consumed significantly less saturated fat and simple sugars and more complex carbohydrates than did non-Hispanic whites. Hispanics residing in the United States for a longer time tended to have macronutrient profiles more similar to those of the non-Hispanic whites. Rice for Hispanic and bread for non-Hispanics were the major contributors of energy. More acculturated Hispanic elders consumed fewer ethnic foods and more foods related to the non-Hispanic-white eating patterns than those less acculturated. APPLICATIONS/CONCLUSIONS: Efforts to promote better diets among Hispanic elders need to emphasize maintenance or adoption of healthful dietary patterns based on ethnic and modern foods that will satisfy their biological, emotional, and social needs. Dietitians and other dietetics practitioners can use the information presented here in studying nutrition-related chronic diseases, in public health planning, and in nutrition education and promotion efforts directed to ethnic-specific, elderly Hispanic groups.
