ABSTRACT
PIP: Changes in the nutritional status of the population under five years of age enrolled in Chile's National System of Health Services between 1975 and 1990 were studied, and their relationship to changes in the purchasing power of the population and to nutrition programs was assessed. A time series was constructed using quarterly data from 1975 to 1990 for the dependent and independent variables. The dependent variable was the nutritional status of children under five, assessed by weight for age from Ministry of Health records. The independent variables were income, purchasing power, cost of the basic food basket, and supplementary feeding programs. Various sources of official statistics were utilized in constructing the indicators. A multiple regression analysis was carried out for each series to determine the origin of variation. The procedure allowed for estimation of a regression model correcting by the autocorrelation of errors. A negative trend was observed in the total malnutrition rate for children under five, which was attributed to the decline between 1975 and 1982. After the first quarter of 1982 the trend stabilized at around 8 to 9%. The series also showed a pattern of seasonality, with the greatest prevalence of malnutrition in the first quarter corresponding to the summer. Purchasing power remained stable, especially in low income groups, and also presented seasonal trends, with purchasing power greatest in the summer months. Spending on nutrition programs did not present significant variation. It was concluded that a trend to decline of malnutrition occurred but was not related to the behavior of the other series studied except during 1975-82, when the socioeconomic indicators improved and malnutrition declined.
