Childhood obesity continues to be a leading public health concern that disproportionately affects low-income and minority children. Children who are obese in their preschool years are more likely to be obese in adolescence and adulthood and to develop diabetes, hypertension, hyperlipidemia, asthma, and sleep apnea. One of the Healthy People 2010 objectives (19-3) is to reduce to 5% the proportion of children and adolescents who are obese. CDC's Pediatric Nutrition Surveillance System (PedNSS) is the only source of nationally compiled obesity surveillance data obtained at the state and local level for low-income, preschool-aged children participating in federally funded health and nutrition programs. To describe progress in reducing childhood obesity, CDC examined trends and current prevalence in obesity using PedNSS data submitted by participating states, territories, and Indian tribal organizations during 1998-2008. The findings indicated that obesity prevalence among low-income, preschool-aged children increased steadily from 12.4% in 1998 to 14.5% in 2003, but subsequently remained essentially the same, with a 14.6% prevalence in 2008. Reducing childhood obesity will require effective prevention strategies that focus on environments and policies promoting physical activity and a healthy diet for families, child care centers, and communities.
儿童肥胖仍然是一个主要的公共卫生问题，对低收入和少数族裔儿童的影响尤为严重。学龄前肥胖的儿童在青少年期和成年期更有可能肥胖，并患上糖尿病、高血压、高脂血症、哮喘和睡眠呼吸暂停。《健康人民2010》的目标之一（19-3）是将肥胖儿童和青少年的比例降至5%。疾病预防控制中心的儿科营养监测系统（PedNSS）是唯一在国家层面汇编的肥胖监测数据来源，这些数据来自参与联邦资助的健康和营养项目的低收入学龄前儿童，由州和地方收集。为了描述在减少儿童肥胖方面取得的进展，疾病预防控制中心利用参与的州、领地和印第安部落组织在1998-2008年期间提交的PedNSS数据，研究了肥胖的趋势和当前患病率。研究结果表明，低收入学龄前儿童的肥胖患病率从1998年的12.4%稳步上升至2003年的14.5%，但随后基本保持不变，2008年的患病率为14.6%。减少儿童肥胖需要有效的预防策略，重点关注促进家庭、儿童保育中心和社区进行体育活动和健康饮食的环境及政策。
