女孩健康丰富多点研究 (GEMS)
研究概览
详细说明
背景:
与白人和西班牙裔女性相比,黑人女性肥胖率高可能是导致她们心血管疾病死亡率更高以及糖尿病和高血压患病率更高的一个因素。 尽管西班牙裔女性的肥胖率也很高,但心脏病死亡率低于黑人或白人女性,糖尿病死亡率低于黑人女性。
黑人女性肥胖患病率的增加在儿童时期就存在,黑人女孩肥胖患病率的增加速度快于白人女孩。 第三次全国健康和营养检查调查 (NHANES III) 的最新数据显示,在青春期前的 6-11 岁期间,30.7% 的黑人女孩超重,而白人女孩的这一比例为 22.0%。 此外,在过去 30 年中,这个青春期前年龄组的肥胖患病率在黑人女孩中增加了 150%,而在白人女孩中增加了 40%。 12 至 17 岁青少年的肥胖患病率同样很高,黑人女孩为 29.9%,而白人女孩为 20.7%。 在过去 30 年中,白人女孩在青春期前和青少年年龄组的肥胖率增加了 35%,但对于黑人女孩来说,较年轻的年龄组(流行率高出 150%)比年长的年龄组增加得更多(增加 80%)。
儿童和青少年预防心血管疾病干预研究特别重点小组 (SEP) 于 1997 年 9 月召开会议,以审查预防和改善儿童和青少年已知心血管疾病危险因素的干预措施的功效和有效性,并为未来制定建议预防性干预研究。 该倡议是根据 SEP 的建议制定的。 RFA 于 1998 年 4 月发布。
设计叙述:
女孩的健康丰富多点研究 (GEMS) 是一系列研究,旨在开发和测试干预措施,以防止非裔美国女孩在进入青春期和进入青春期时体重过度增加。 该研究作为四个相互依赖的临床试验进行。 他们是“相互依存的”,因为他们正在考虑相似的研究人群,遵循相似的随访时间表并使用一套“核心”评估程序。 尽管如此,GEMS 并不是通常意义上的“多中心临床试验”——每个现场中心都在评估自己的干预措施(和相应的对照)。 因此,每项研究都将具有很高的内部有效性,并将作为一项独立的研究进行设计和分析。
在第一阶段,开发了几种不同且独立的干预措施。 干预措施涉及饮食、身体活动以及社会心理和家庭影响。 第一阶段有四个参与中心,包括孟菲斯大学、斯坦福大学、明尼苏达大学和贝勒医学院。 协调中心位于乔治华盛顿大学。
在第二阶段,将支持个体临床试验以测试第一阶段开发的干预措施的有效性。 尽管每个现场中心开发的干预措施都是独一无二的,但这些中心将合作标准化关键测量、结果和主要分析方法。 孟菲斯实地中心将在 300 名高风险、青春期前的非洲裔美国女孩及其父母中进行为期两年的全面随机对照临床试验,以预防体重增加。 体重指数是主要终点。 次要终点包括饮食摄入量、身体活动和社会心理变量。 斯坦福野外中心将进行一项双臂平行组随机对照试验,以测试课后舞蹈计划和基于家庭的干预措施的效果,以减少 260 名非裔美国人使用电视、录像带和视频游戏来减少体重增加青春期前的女孩。 活跃的安慰剂组将接受基于信息的社区健康教育干预。 干预将持续两年。 体重指数是主要的结果指标。
