An increase in migration has changed Spain’s demographic profile in recent years, enabling researchers to study the micro-adaptive transition of immigrant people. As a result, adolescents have become the most vulnerable population as this is the stage of the main growth and maturing processes.
The start of menstrual cycles (menarche) is one of the pillars of reproductive development and highly sensitive to the environmental context and health of the population. The study showed that immigrant girls experience a greater somatic and morphological change than native girls when passing from a pre-menstrual to a post-menstrual stage.
“Immigrant girls have a higher body mass index and higher body fat percentage than Spanish girls when they reach reproductive maturity, as well as higher truncal fat accumulation, which is related to cardiovascular and metabolic diseases”, Raquel Fernández, the main author of the study, explained to SINC.
The research was carried out in four schools in the Madrid region and analysed 284 girls between 9 and 16 years old, who were assessed over a two-year period. The average age for beginning mental cycles was 12.46 years old for native girls and 12.57 years old for immigrants, all who came from Latin America.
Need for focused health campaigns
After analysing the relationship between the variables, the researchers established two subgroups: Spanish girls with normal weight and regular menstrual cycles, and immigrant girls with excess weight and irregular cycles. According to Raquel Fernández, “these results suggest the need to create health campaigns focused on the adolescent immigrant population in order to adopt healthy lifestyles”.
The aim of the study, the result of work carried out over the last four years by scientists from the Autonomous University of Madrid (Universidad Autónoma de Madrid) is to get children and young people to adopt healthy lifestyles and provide families with guidance for following preventive lifestyles against the appearance of certain diseases throughout their life.
“Although there are campaigns that highlight the importance of having a balanced diet and adopting a healthy lifestyle, studies such as this show that we are still a long way from getting children and young people to follow these recommendations”, Fernández indicated to SINC.
The special characteristic of this study was the preparation by the authors of a personal report for each of the girls. In addition, fathers and mothers received a summary with their children's measurements, ideal values for their age and sex, and personal recommendations for improving their quality of life.
“Excess weight is still very prevalent at this age and both diet and physical exercise differ from the recommendations, with this characteristic being especially noteworthy in the immigrant population”, the researcher highlighted.Reference:

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
