Dietary survey of rural elderly in Nigeria.

摘要

112 free living elderly subjects (aged 65-85 years), from Odeda, south west Nigeria, were recruited. Food frequency questionnaires were combined with 24-h recalls to obtain information on food intake. The average food intake increased by 30% duringthe rainy season due to increases in cereals, tubers, roots and vegetables, resulting in a 20% increase in energy intake. Compared to the recommended daily allowances (RDA), energy intake was below requirements, 58% RDA for females and 60% for males. Protein intake was also higher (P<0.05) during the rainy season (from 40 to 50 g/day). Only 10% of total protein intake was derived from animal sources. Most of the subjects met their RDA for Ca, derived mostly from plant sources. Fe intake was marginal when compared with RDA, intakes of both thiamin and riboflavin were inadequate for both males and females during the 2 seasons. It is concluded that the dietary intakes of the elderly do not meet their requirements for energy and a majority of nutrients during the season that the food is plentiful.
