ABSTRACT
A longitudinal principal components analysis was used to summarize trends or intraindividual changes in weight, height, blood pressure, serum cholesterol and triglycerides in 32 boys and 28 girls from the Caracas Longitudinal Study (1976-1982), who started follow-up at age 8. A first component was identified for each variable, it represents a measure of position across the whole age period, a "canalization pattern". This component accounted for most of the total variance. The second component represents an unidirectional change in relative position of the values of the variable, a "decanalization pattern", and a third pattern summarized deviations around a position level "recanalization pattern". The results from the correlation analyses between the components indicate a positive and significant association between the identified trends. These patterns allow predictability of "high and low risk" factors of non-communicable chronic diseases.
