Obesity in childhood is a gateway to many other chronic diseases Long known to dramatically increase the risk of certain chronic diseases later in life, obesity has serious health consequences, immediately after a study by researchers at the University of California Los Angeles and published in the journal Pediatrics. The researchers found that obese children have 30 percent more likely than normal-weight children of at least three health problems, mental or developmental disabilities are obese children 200 percent more. "The results should wake up call for doctors, parents and teachers better on the risks for other disorders associated with obesity, should serve to" lead author Neal Halfon said. Researchers have known for some time that even if the childhood obesity greatly in the last 20 years has increased, so the childhood chronic conditions such as asthma, learning disabilities and Attention Deficit Deficit Hyperactivity Disorder (ADHD). Although previous studies have looked at the link between these phenomena, they either had a small sample size or focus on a single condition or a part of the country. In this study, the researchers found extensive health profiles of almost 43,300 children aged 10 to 17 in the United States. All children participated in the 2007 National Survey of Children's Health. 15 percent had a body mass index (BMI) between the 85th and 95th Percentile (classified as overweight), while 16 percent had a BMI above the 95th percentile (classified as obese). The researchers compared the weight with 21 individual indicators of general health, specific health and psychosocial function. The results were corrected for differences in socio- demographic factors. A number of health The researchers found that obese children emotional significantly more likely than children of normal weight of ill health, more disability, ADHD, allergies, asthma, bone, joint and muscle pain suffered from depression, missed developmental delays, ear infections, and behavioral disorders , headache, learning disabilities, and school, repetition, and other problems in school. "This study provides a comprehensive picture of childhood obesity," Halfon said, "and we were surprised to see how the conditions associated with obesity." Further studies are needed to confirm the present study, noted Halfon and colleagues. In particular, longitudinal studies confirm that obesity causes health related, if there is another factor that explains the connection. "Obesity can be the cause of co-morbidity, co-morbidity, or maybe the cause of obesity - or both may be caused by other factors not measured in the third," says Halfon. "For example, affect the exposure to toxic stress change neuro regulations pulse control in ADHD and given the sensitivity of leptin, which can contribute to weight gain." The researchers said that in all probability the increased prevalence of childhood chronic health problems, the change from decades of long-term trends dramatic social and physical environment of childhood have. They suggested that the prevention of obesity in children and therefore should focus on improving the environment of the child, during the screening of children at risk for obesity and related diseases.
