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:

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
