People suffering from severe obesity (index Bodymass index [BMI] 40 or higher) encounter serious and potentially fatal complications. "In 2000, approximately 2.2 percent of adults, or 4.8 million people, were severely obese, with a prevalence disproportionately high among women and racial and ethnic minorities." However, few national studies follow further to understand the progression of severe obesity overweight people, "the authors write.""Understanding individuals are at risk of severe obesity is essential to determine when interventions should be implemented to prevent the progression toward obesity serious people obèses.Bien observational studies have reported that the prevalence of overweight and obesity severe obesity have increased in recent years, people who are obese early in life have not been studied longitudinally to determine their risk of developing serious adult obesity."
Natalie Dr.., of the University of North Carolina at Chapel Hill, and colleagues conducted a study to determine the incidence and risk of severe obesity in adulthood among people who were obese during adolescence.Study group consisted of 8,834 individuals between the ages of 12 and 21 years, who were enrolled in 1996 in the National Longitudinal Study of Adolescent Health of United States, followed in adulthood II wave (ages 18-27 years waves III [2001-2002]) 24-33 years in the wave IV [2007-09] .i got measurements of size and weight of participants and survey administered in the homes of the participants in the study of standard procedures. New cases of severe adult obesity were calculated by sex, race or ethnic origin and the State of weight among teenagers, and the results were weighted for national representation.
In 1996, 79 adolescents (1.0%) were seriously obèses.60 (70.5%) remains severely obese as adults. In the period of 13 years among adolescents (1996) and age adult (2007-2009), a total of 703 new cases of severe obesity in adulthood were observed, indicating a total rate of 7.9%.Researchers have discovered that people suffering from serious incident obesity in adulthood had a higher adolescents BMI and were more likely to be racial and ethnic minorities compared with people without severe obesity.
"A significant proportion of obese adolescents become severely obese by their beginning in the 1930s, with significant variation in the sexe.Parmi people who were obese as adolescents, severe obesity incident was 37.1% for men and 51.3% among women." Obesity serious incident is highest among black women to 52.4 %.Dans all sexual relations and racial or ethnic groups, less than 5 percent of people who have normal weight in adolescence becomes severely obese as adults, "the authors write."
The analysis indicates that obese adolescents were much more likely to develop severe obesity than adolescents normal weight or excess weight, with a variation on race or ethnic origin and sex.
"The clinical consequences of these observed trends are given co-morbidities and chronic associated with severe obesity the disease."Results highlight the need for interventions before adulthood to prevent the progression of severe obesity, which can reduce the incidence of severe obesity obesity and potentially life-threatening consequences.»
