Each of the 4.231 participant children in the 2004 Birth Cohort has a very important role for the development of the health researches in an international level. This group of children has been essential for the development of public actions that aim the national and international improvement of the population's health.
The data of the 2004 Birth Cohort has proved that with serious and planned measures it is possible to reverse the huge Brazilian public health problems, such as child mortality. In 1982, when the first birth cohort study started, Pelotas had a very high child mortality rate. There were 36 deaths of every 1.000 children. Since then, the researchers aimed their analyses in preventing those deaths, and they noticed that most deaths could be avoided.
In the course of 22 years, a series of actions have been implemented at the city due to the real numbers found in the researches, in order to reduce the premature births and to implement campaigns of incentive for breastfeeding. The result was the reduction of mortality rates almost by half. In 2004, there were 19,4 deaths of every 1.000 children, and three years later this number was reduced by 12,3.
These data was only known because of the collaboration of all mothers who, a little after their childbirth, accepted to answer a lot of questions to the researchers, and allowed that their newborns were tested for measuring and weight analyses.
More than the collaboration that those mothers gave to the researchers at the hospital, they also gave their addresses and, with no immediate benefit, they have received the researchers a lot of times during many years in order that the researchers could follow their children’s development. All the available time provided by the mothers and by the own participants, and all the work that the researchers had to find those more than four thousand families, are nowadays worth for the scientific knowledge that is available for the population.
The rate of breastfeeding increased a lot in 22 years:
On the one hand, the rate of breastfeeding increased a lot in 22 years:
On the other hand, child mortality decreased in 22 years:
Even with the decrease in mortality rate, the researchers keep working to decrease more the number of deaths among children. It is known that the reduction of premature births and the breastfeeding are important factors to avoid children’s death in their first year of life.
Developed children were stimulated through the following means:
Studies have proved that besides the activities listed above, playing games, role-playing games, and guessing games stimulate children’s development in their first years of life.
