A study links low vitamin D in young girls with early menstruation, which is a risk factor for a host of health problems for teen girls as well as women later in life. Researchers from the University of Michigan School of Public Health measured the blood vitamin D levels in 242 girls ages 5-12 from Bogota, Colombia, and followed them for 30 months. Girls low on vitamin D were twice as likely to start menstruation during the study than those with sufficient vitamin D, said epidemiologist...

Women who suffer from asthma or poor lung function as adults generally started their periods at the age of 10 or before. This is the conclusion of a European research study with Spanish participation, which shows that this trend is more common in southern Europe, and particularly affects women from large families. "Adult women who had their first menstruation at the age of 10 or earlier have significantly lower lung capacity than women who had their first period at 13", Ferenc Macsali, lead...

University of Minnesota School of Public Health researcher Ellen Demerath, Ph.D., is among an international group of researchers that has identified 30 new genes responsible for determining the age of sexual maturation in women. Many of these genes are also known to influence body fatness, obesity, and energy metabolism. Prior to the multi-institutional study, only four genes had been identified as contributing to the process. The findings, which were reported in Nature Genetics, help to...

Scientists have discovered 30 new genes that control the age of sexual maturation in women. Notably, many of these genes also act on body weight regulation or biological pathways related to fat metabolism. The study, which appears in Nature Genetics, was a collaborative effort by the international ReproGen consortium, which included 175 scientists from 104 worldwide institutions, including Boston University School of Medicine (BUSM) and Boston University School of Public Health. Menarche, the...

(Ivanhoe Newswire) "“ Look out moms! Girls who live in a home without a father are more likely to hit puberty at an earlier age. The study found that in a home where the biological father was absent, the daughter developed breasts and pubic hair quicker. This is only true for girls in high-income homes. "The age at which girls are reaching puberty has been trending downward in recent decades, but much of the attention has focused on increased body weight as the primary culprit," the...

Girls in homes without a biological father are more likely to hit puberty at an earlier age, according to a new study led by researchers at the University of California, Berkeley's School of Public Health. The findings, to be published Sept. 17 in the Journal of Adolescent Health, found that the absence of a biologically related father in the home predicted earlier breast and pubic hair development, but only for girls in higher income households. The findings held even after the girls' weight...

Researchers at the University of Helsinki and the Institute for Molecular Medicine Finland (FIMM) have shown that a gene called LIN28B strongly influences height growth from birth to adulthood in a complex and sex-specific manner. Human growth in height is a multifaceted process including periods of accelerated and decelerated growth velocities. The postnatal growth trajectory can be conceptualized as consisting of three partially overlapping phases: infant growth characterized by rapidly...

When humans and animals delay reproduction because food or other resources are scarce, they may live longer to increase the impact of reproduction, according to a new study by University of Minnesota researchers published in the June 25 issue of PLoS (Public Library of Science) One.The discovery, which explains why starvation can lead to longer life, has important implications for improving human health and lengthening lifespan.The basic premise is that individuals use environmental cues to...
