[Secular height trend: a literature review].
This paper presents a literature review of secular height trends. The principal topics included were definition of the phenomenon, use of historical data sets on height as an alternative approach for monitoring economic changes, the main theoretical explanations of the phenomenon, the beginning of military anthropometry, and past and current use in measuring secular height trends in recruits and children. The most important results showed that the positive secular trend can be attributed to environmental influences, especially improvements in health, economic, and social conditions. The mean reported rates in height increases varied with age, socioeconomic status, and country, so one must exercise caution in drawing inferences. World War II slowed the trend in several countries, including Brazil, but the trend was stronger in the post-war period than in the beginning of the century. Finally, we observed that data from military anthropometry are the most common source for estimating secular height trends.
