Received: 16 December 2016 Accepted: 13 AugustConclusion In summary, obesity and overweight are negatively correlated with delayed puberty in girls. Body compositions, such as BF, FM and FFM are negatively correlated with delayed puberty and BD are positively correlated with delayed puberty in girls. But the relation between obesity or body compositions with timing of puberty was not found in boys. Prospective cohort studies are needed to determine the causality of timing of puberty and obesity and also whether the Bayer 41-4109 price Association between body compositions and timing of puberty merit further attention.References 1.
