Summary: | OBJECTIVE: The purpose of this study was to estimate the secular trend/change in the height of young males born in the city of S. Paulo between 1950 and 1976 and measured in the year they turn 18 years. METHODS: A random and representative sample (6,942 individuals) was evaluated in military draft. Statistical analyses included Shapiro-Wilk test for normality of height distribution in each birth cohort, and linear regression analysis for trend on heights. RESULTS/CONCLUSIONS: Stature has increased 3.42 centimeters during the 27 years covered by the study (1.26 cm/decade). The trend was not linear: in the 50s, there was a statistically significant increase (0.84 cm/decade); in the 60s, a smaller but non-significant increase (0,5 cm/decade) was seen; in the period of 1970-76, a greater increase in heights (2,9 cm/decade) was observed. The secular change rate observed was comparable to the rate seen in other countries. The most recent birth cohorts (1975 and 1976) achieved the higher statures in the study (~175 cm). Despite these height increments, deficits of 1.8 e 6.2 cm were seen when the taller cohorts of the study were compared to American young males born in 1961 (NCHS) and Dutch men born in 1972. If there won't be any changes in the accelerated rates of the 70s, young people of São Paulo may overcome these deficits in about one or three decades. |

OBJETIVO: Estimar a tendência/mudança secular das estaturas de jovens do sexo masculino, aos 18 anos de idade, nascidos na cidade de São Paulo, SP, entre 1950 e 1976. MÉTODOS: Foi coletada amostra aleatória e representativa de 6.942 indivíduos avaliados no alistamento militar. A análise estatística compreendeu a avaliação da normalidade da distribuição estatural (teste de Shapiro-Wilk) e a análise da tendência pelas técnicas de regressão linear. RESULTADOS/CONCLUSÕES: A distribuição das estaturas foi considerada normal para todas as coortes. O aumento total das estaturas foi de 3,42 centímetros ao longo dos 27 anos do estudo (1,26 cm/década). A tendência no período não foi linear, havendo aumento significativo na década de 50 (0,84 cm/década), aumento não significativo na década de 60 (0,5 cm/década) e aumento expressivo no período 1970-76 (2,9 cm/década). O ritmo de mudança secular observado é comparável ao de outros países e estados do Brasil. As coortes mais recentes (1975 e 1976) atingiram a maior estatura (~175 cm); contudo, este valor ainda indica déficits de 1,8 cm e 6,2 cm quando comparado às estaturas de jovens americanos nascidos em 1961 (NCHS) e holandeses em 1972. Mantidas as aceleradas taxas de mudança secular da década de 70, os jovens paulistas poderão recuperar estes déficits entre uma a três décadas. Isto indica a necessidade de contínua monitoração da tendência secular das alturas na cidade de São Paulo. Universidade de São Paulo.
