Because an increasing number of children in the United States are obese, childhood and adolescent obesity is individual of today's most important health challenges and public health belong tos Further exacerbating this challenge are the many immediate and long-term adverse issues associated with obesity.

The Center for Disease check and Prevention (CDC) uses the bound "overweight" rather than "obesity" in the child and adolescent populations and classifies overweight according to brace levels: (1) being at risk for overweight, which corresponds to a dead body mass index (BMI) from the 85th by the and of the 95th percentiles for age and sex and (2) being overweight, which corresponds to a BMI greater than the 95th percentile for age and sex (1)

The prevalence of overweight and at-risk status among children and adolescents has rapidly increased from one side of to the other the past 40 years. (12) Prevalence estimates for overweight in characters six to 19 years of age has tripled since the 1960 (Figure 1) (12) The greatest in number recent National Health and Nutrition Examination review (NHANES) (2) estimates that 206 percent of children couple to five years of age, 30 (3) percent of children six to 11 years of age, and 30 (4) percent of adolescents and young adults 12 to 19 years of age are overweight or at risk for becoming overweight. Black and Hispanic children are greatly more likely to be overweight than white children (Table 1) (1) Multiple nonbehavioral risk factors for overweight in children have been identified; they include sex race/ethnicity, socioeconomic status, and having parents who are obese. (34)

The adverse health issues resulting from overweight include short-term deductions during childhood and long-term events that manifest in adulthood. The in the greatest degree common short-term consequences are psychosocial vexed questions (5) Eating disorders have a higher prevalence among children and adolescents who are overweight, especially binge-eating, which has an estimated prevalence in overweight female adolescents of 30 percent

Nonpsychologic health deductions of overweight are less public in childhood and adolescence than in adulthood. However, as the prevalence of overweight in children and adolescents increases, nonpsychologic health results may become more common in these populations. It is likely that newly come increases in the rates of impaired diabetic sugar tolerance and type 2 diabetes among children and adolescents are attributable to the increased prevalence of overweight. (67)

The impact of adolescent overweight widens into adulthood. Adolescents who are overweight have an increased risk of morbidity from coronary artery disease and arthritis in adulthood, independent of their weight as adults, (8) and are more likely to be overweight as adults. Obesity in adulthood is perhaps the chiefly serious of all consequences because it is associated with increased mortality and morbidity from a variety of conditions. (910) Overweight in adolescence also is associated with adverse social and economic ends in adulthood. (11)

undivided of the national public health objectives in the "Healthy the public 2010" initiative is a reduction of 50 percent or more in the prevalence of childhood and adolescent overweight. (12) Effective prevention and treatment strategies are essential to achieving this goal.

Data Sources

Candidate studies for inclusion in this review were identified from searching MEDLINE (OVID platform) with the first note of the scale word "obesity" (subheadings: diet therapy, prevention and hinder drug therapy, therapy); a inquiry date between January 1990 and December 2002; English language; human; and infant or child. Further candidate articles and data sources were identified by means of searches of the Cochrane Database of Systematic Reviews, and the Web sites of the National Institutes of Health, the CDC and the National Guideline Clearinghouse. Other sources of articles included bibliographies of review articles that specifically addressed overweight prevention or treatment in children and adolescents.

Studies were considered simply if the primary aim was overweight prevention or treatment and were large observational studies or randomized controll trials (RCTs) using more than 50 patients. Studies were not considered if they measured results at less than 12 month post-intervention or did not use consequences that included weight or BMI measurements. Several consensus/expert opinion guidelines issued by means of medical panels or organizations also were reviewed.

Prevention

Interventions to hinder overweight are often population-based, like as school or community programs, and attempt to change institutional policies as well as individual behaviors.

Seven studies that used a population approach to the prevention of overweight in preschool- or school-aged children and adolescents were identified (Table 2) (13-19) reject for one clinical cohort meditation these studies used a no-intervention govern group or a control dispose with an alternate strategy. principally of the studies were randomized. All nevertheless one study were conducted outside of the United States.
