One approach to the study of the growth and development of human settlements is through the analysis of changing residential patterns. The focus of this paper is upon the changing density patterns for Puerto Rico's three principal metropolitan areas from 1899–1970. The data show that San Juan's long-run residential deconcentration is consistent with the pattern usually displayed by cities in developed societies. The increasing congestion and stable concentration of Ponce and Mayaguez are consistent with the pattern found in cities in developing societies. Differences among the metropolitan areas are discussed in terms of the trajectory of Puerto Rico's economic development.

Follow Up Study

The Institute of Nutrition of Central America and Panama (INCAP) carried out a longitudinal study of the effects of nutritional improvements on growth and development in early childhood in four villages in eastern Guatemala, 1969–1977, with a preparatory survey in 1967 and a follow-up study of the participants in 19881989. This paper examines differences among the four villages in education, occupation, quality of housing, and demographic profiles over a 20-year period, focusing on comparisons between the two villages that received a high-energy, high-protein supplement and the two that received a low-energy supplement at two different times: before the initial longitudinal study and before the follow-up study. The results suggest gradual improvement in all the villages on a number of indicators. However, the two pairs of village were not comparable on all measures; of particular concern for the interpretation of effects on cognitive development are differences in education.

This is a clear, well-organized account of a longitudinal study of several hundred prematurely born and full-term children, born in Edinburgh in 1952 and 1953. Starting with 595 children, 251 singletons weighing 5 lb 8 oz or less at birth, 119 full-term singletons as controls and 225 twins of all birth weights, Dr. Drillien was able to follow nearly 90 percent to school age. Besides the main survey group, she added a supplementary group of children of very low birth weight (3 lb or less) born between 1948 and 1960; in all, 110 children in this birth weight group were traced, and 72 followed to school age.

In the Amsterdam Growth And Health Longitudinal Study (AGAHLS), a group of approximately 650 12- to 14-year-old boys and girls was followed in their growth, and development of their health their lifestyle including diet, physical activity and smoking. One of the main interests was the change in their aerobic fitness. From 12 to 36 years of age in total, eight repeated measurements were performed to measure peak oxygen uptake (peak VO2). In this study the data of peak VO2 are revisited and extended: We made use of all collected data as a mixed longitudinal design including cross-sectionally measured subjects as well as longitudinally measured subjects. This led to the availability of 1,194 boys and 1356 girls. With generalized estimating equations (GEE) the longitudinal changes with chronological age and differences between boys and girls were analyzed. Teenage boys and girls increased their peak VO2 (ml/min) significantly (p < .001) until age 14 in girls and until age 17 in boys. However peak VO2 relative to bodyweight (peak VO2/BW) had significantly (p < .001) decreased over the whole age range from 12 to 36 in both sexes. Vigorous physical activity (VPA) also showed a decrease and was significantly (p < .001) related with lower peak VO2/BW (Beta = 0.001). This relation was stronger in boys than in girls. Because at the start of AGAHLS no fast responding metabolic instruments were available, future longitudinal studies about aerobic fitness should include also measurement of VO2 kinetics.
