客观的。国家心肺血液研究所生长与健康研究 (NGHS) 是一项为期 10 年的研究，旨在调查青春期黑人和白人女孩肥胖的发展情况及其环境和心理社会相关性。本报告的目的是调查 NGHS 队列中 9 至 19 岁超重和肥胖年患病率的变化。参与者和环境。总共 2379 名 9 至 10 岁的黑人和白人女孩是从加利福尼亚州里士满和俄亥俄州辛辛那提的学校以及华盛顿特区地区的一个健康维护组织的家庭中招募的。参与者资格仅限于自称是黑人或白人并且生活在种族和谐家庭中的女孩及其父母。设计和统计分析。 NGHS 是一项针对混血儿队列的多中心前瞻性研究，每年对 9 至 10 岁至 18 至 19 岁的人群进行随访。超重和肥胖的患病率基于年龄特定的分别大于或等于第85个百分位值和大于或等于第95个百分位值，基于1960-1965年全国健康体检参考人群的体重指数。 主要结果指标。主要结果指标是体重指数（以公斤为单位的体重除以以米为单位的身高，平方）以及按年龄和种族划分的“超重”和“肥胖”女孩的比例。 结果。即使在 9 岁时，黑人的超重发生率也比白人高出 37%（30.6% vs 22.4%）。在 10 年间，两组的超重率几乎翻了一番。到 19 岁时，黑人女孩的超重率为 56.9%，白人女孩的超重率为 41.3%。 9 岁时，黑人女孩的肥胖率为 17.7%，白人女孩的肥胖率为 7.7%，并且该比率在研究期间也翻了一番。结论。黑人和白人 NGHS 女孩青春期超重和肥胖的患病率翻了一番，令人惊讶。到 19 岁时，一半以上的黑人女孩体重超重，三分之一以上肥胖。近一半的白人女孩体重超重，近五分之一的女孩肥胖。这些发现应该给所有初级保健医生和公共卫生专业人员敲响警钟，让他们关注我们年轻人身上发生的事情。
Objective. The National Heart, Lung, and Blood Institute Growth and Health Study (NGHS) is a 10-year study to investigate the development of obesity in black and white girls during adolescence and its environmental and psychosocial correlates. The purpose of this report was to examine changes in the annual prevalence rates of overweight and obesity in the NGHS cohort from ages 9 to 19 years.Participants and Setting. A total of 2379 black and white girls, aged 9 to 10 years, were recruited from schools in Richmond, California, and Cincinnati, Ohio, and from families enrolled in a health maintenance organization in the Washington, DC area. Participant eligibility was limited to girls and their parents who declared themselves as being either black or white and who lived in racially concordant households.Design and Statistical Analysis. The NGHS is a multicenter prospective study of a biracial cohort followed annually from ages 9 to 10 years through 18 to 19 years. The prevalence of overweight and obesity was based on age-specific greater than or equal to85th and greater than or equal to95th percentile values, respectively, for body mass index based on the 1960-1965 National Health Examination Survey reference population.Main Outcome Measures. The main outcome measures were body mass index (weight in kilograms divided by height in meters, squared) and proportions of girls who were "overweight" and "obese" by age and race.Results. The prevalence of overweight was 37% higher in blacks as compared with whites (30.6% vs 22.4%) even by age 9. The rate of overweight almost doubled in both groups during the 10-year period. By age 19, the rate of overweight was 56.9% in black and 41.3%, in white girls. The prevalence of obesity was 17.7% in black and 7.7% in white girls at 9 years old, and the rates also doubled during the study period.Conclusions. The doubling in the prevalence of overweight and obesity during adolescence in black and white NGHS girls was surprising. By age 19, more than half of black girls were overweight and more than one third were obese. Almost half of white girls were overweight and almost 1 of 5 girls were obese. These findings should sound an alarm for all primary care physicians and public health professionals to take heed of what is happening to our youth.
