Maturational profiles and migration in the female adolescent population of Madrid: is there a need for a new perspective?

The aim of this study is to assess anthropometric changes and menstrual cycle characteristics during the maturation process of an adolescent female sample in Madrid, Spain. The new demographic context of Madrid, with a 33.9% of girls coming from Central and South America, makes this study relevant in terms of new epidemiological situations that could possible develop. The sample consists of 284 girls, ages 9 to 16 years, measured and interviewed in four school centres of Madrid. Results show that menarche is slightly earlier in the Spanish girls, but there are no other important differences regarding the characteristics of their menses. However, the Spanish girls have a significantly higher intake of menarcheal pain related drugs. The anthropometric changes accompanying menarche are greater in the immigrants, especially in terms of trunk fatness, leading to an "overweight" characterisation of this sub-sample. These maturational profiles show the need for educational programs, especially focussed on the foreign adolescent population, to cope with health risks related to overweight.
