YES, TO SOME DEGREE-BUT IT IS OF UNCERTAIN CLINICAL SIGNIFICANCE. OVER A PERIOD OF 6 MONTHS, METFORMIN MODESTLY REDUCED WEIGHT (-2.1 KG) AND BODY FAT MASS (-1.9%), BUT NOT BODY MASS INDEX (BMI) OR LEAN BODY MASS, IN ADOLESCENTS WHO WERE OVERWEIGHT OR OBESE. THIS IS COMPARABLE TO LIFESTYLE INTERVENTIONS (DIET AND EXERCISE) SUPPORTED WITH > 26 HOURS OF COUNSELING, WHICH MODESTLY IMPROVED BMI BUT NOT WEIGHT. (STRENGTH OF RECOMMENDATION [SOR]: A, BASED ON A LARGE META-ANALYSIS OF RANDOMIZED CONTROLLED TRIALS [RCTS] OF VARIABLE QUALITY).
是的，在一定程度上是这样——但这具有不确定的临床意义。在 6 个月的时间里，二甲双胍适度减轻了超重或肥胖青少年的体重（-2.1 公斤）和体脂量（-1.9%），但没有减轻体重指数（BMI）或去脂体重。这与生活方式干预（饮食和运动）相当，生活方式干预支持超过 26 小时的咨询，适度改善了 BMI，但没有减轻体重。（推荐强度[SOR]：基于对 RCT 进行的大型荟萃分析[A]，RCT 质量存在差异）。
