SONCINI, Ana Silveira; VARGAS, Deisi Maria; ARENA, Mariana Garcia Lopes  and  ARENA, Luiz Fernando Garcia Lopes. Secular trend of growth in Blumenau, Santa Catarina State. Ciênc. saúde coletiva [online]. 2011, vol.16, suppl.1, pp.1275-1280. ISSN 1678-4561.

Secular trend of growth refers to any change of the corporal size in determined population group in long periods of time. The objective of this work is to study the secular tendency of growth in natural height among recruits in Blumenau, Santa Catarina State, between the years of 1963 and 2007. This is a transversal, retrospective and analytical study. Young recruits, aged 18 to 20 were chosen as the population. A standardized database was used on individual records with the first 40 records of each year being selected. Data from 1963 to 2007 were collected and separated per decades. A margin of error not higher than 3.5% was used as a demonstration, which resulted in a sample of 600 individuals. The t-test was used to compare the averages of different decades. The results showed an increase of 7 cm in the height of the population in Blumenau in the last 50 years. The positive trend that is occurring in our country in the most recent evaluations can be attributed to better sanitary, economic and social conditions. The secular tendency of growth in height was positive in the municipality of Blumenau. It was found that the population increased 7 cm in the final height in the last 50 years with a growth rate of 0.14 cm/year or 1.4 cm/decade.
