New generation of adolescents are at greater risk of heart disease
Of those analyzed, many suffer from high blood sugar, are obese and overweight, have a poor diet, do not exercise enough and smoke. These children represent a sample of the 33.1 million children and adolescents of the United States, and are part of the National Health and Nutrition Examination Surveys, analyzed from 2003 to 2008.
All of them have a diet considered terrible by the researchers, being even worse than the two adults.
More than 30% of boys and 40% of girls have high blood sugar levels, putting them in the blood. at high risk of developing type 2 diabetes. Altogether, 35% of adolescents of both sexes are in the range of obesity or overweight. Only 38% of girls have physical activity levels considered to be ideal, with boys rising to 52%.
Girls also have lower rates of cholesterol than boys: only 65% compared to 73% of them. Almost 25% of adolescents smoked in the month prior to the study. As for blood pressure, most boys and girls (92.9% and 93.4%, respectively) have the pressure under control.

Heart of children suffers from obesity
Another study carried out by the Physiotherapy Faculty of PUC-Campinas, with 45 children aged nine to 11 years of age. age, separated into groups of non-obese, obese and morbidly obese, has shown that the cardiovascular performance of children is seriously affected by the extra pounds.
One of the findings is linked to limitation during physical activities, which can generate a vicious cycle , according to the professor and researcher of the Faculty Mario Augusto Paschoal. "Morbid obese children have a major cardiorespiratory limitation when subjected to physical exertion compared to healthy children of the same age."
Bad Habits of the Heart
This aspect causes obese children not to engage in physical activity due to demotivation, and this leads them to gain weight even more and become more sedentary, closing the cycle. "
The study also revealed that morbid obese children reached only 48.7% of the oxygen consumption value obtained at peak physical exertion if compared to that reached by the group of non-obese children. "For the health of the cardiovascular system, it is lousy because obesity leads to high blood pressure, diabetes and the development of vascular diseases because of the deposit of fat plaques in the vessels, with a much greater future risk of myocardial infarction, for example , and cerebrovascular accidents, increasing morbidity and mortality rates, "explains Mario Augusto Paschoal.
We live in a country where spending leisure time in environments with water (swimming pools, beaches, lakes, dams) is part of the culture. For this reason, learning to swim in infancy can make parents feel more comfortable about their children's safety. It is very common for parents to think that children's swimming lessons are similar to adults.
Every parent knows that a quiet night is one in which a baby can sleep well, without crying until dawn. For this to occur, it needs to be nourished, healthy and feel in a protected and dependable environment. Even so, with all the favorable conditions, other factors can make you unable to sleep. Immediately after birth, the baby sleeps for almost 24 hours.
