Early Puberty and Problems of Infertility associated with Childhood Obesity

(Best Syndication News) - An overview of childhood obesity emphasizes the potential impact it has for early puberty and infertility problems, particularly with girls. Patrick Chappell, an assistant professor of veterinary medicine at Oregon State University, is the author of the report, which was published in Frontiers in Endocrinology.

Chappell explains that nutritional conditions play a vital role in reproduction. Obesity is known to be associated with metabolic syndrome, which can affect fertility. The lack of nutrition can also cause reproduction problems.

Generally, girls are starting puberty earlier and it has accelerated.

One theory as to why fertility is impacted is that kisspeptin, a neurohormone, is needed for reproduction and it could be disrupted from endocrine signals that come from fat.

A disrupted circadian clock might be causing early puberty and infertility problems. The circadian clock is the natural body rhythms and changes from day and night. If the sleep-wake cycle has been disrupted, then hormones such as coritsol, testosterone, and insulin could be secreted.

Chappell explained that if the circadian clock is disrupted, this could further interrupt normal metabolism affecting sleep and interfering with reproduction. He said that diet and metabolism could affect the circadian clocks throughout the body.

The report found certain studies that associated early puberty with an increased risk of reproductive cancers, type 2 diabetes, and metabolic syndrome. There was also an increased tendency for girls to suffer anxiety and depression if they had early onset puberty. Risky behaviors such as smoking and early sexual interactions were associated with boys and girls who had early puberty.

The author of the review suggests that more research on this subject would be needed to further understand the role childhood obesity has on metabolism, hormones, and other development issues.
