Abstract:
Overweight and obesity in adolescence often persist into adulthood and it’s accompanied by risks of increased morbidity and mortality in patients being overweight or obese in adolescence.
A cross-sectional study with single elementary sampling nominative list of all college students enrolled in the academic year 2012/2013 has allowed us to estimate the frequency of overweight and obesity in teenagers of Constantine. For that 457 teenagers were recruited.
The frequency of overweight and obesity according to the 2007 WHO reference z-score, is respectively 18.2% and 13.2%, including 1.8% with severe obesity. Overweight and obesity are more prevalent in boys than in girls. Obesity is more common among adolescents who don’t respect the main meal of the day and those who don’t take their family meals. The obese have low nutritional knowledge and less physical activity compared to leans ones. Birth order may be identified as a risk factor. Obesity is more common among adolescents who have
parents with a higher socio-economic and socio-professional status. Breast feeding plays an essential role in the prevention of overweight in childhood and adolescence. Birth weight would influence the weight at the age of 5 and 10 years and at adolescence, anxiety of obese adolescents associated with poor felt the denial of the image of their own body size may increase overweight and obesity among these. Puberty is a critical period in the development of obesity.
The genotype of CD36 gene lingual, rs1761667 (AA) could be responsible for the low
detection of lipids and encourage teenagers to over-consume fat to have the same appreciation that subjects with the other two AG and GG genotypes.
Obesity in adolescence seems to play an important role in predicting very slight increase in glucose and lipid values, insulin and inflammatory, confirming the deleterious role of excess weight on biological data.
Through measures as dietary and behavioral, we can fight effectively against long-term obesity in adolescents.
