Sexual development may be influenced by geographic factors (temperature, humidity, altitude, light), socioeconomic factors (nutrition, public health, family size), and genetic factors (population, familial heredity). Most of them are largely interrelated and difficult to define.

An anamnestic study has been carried out in Israel on Ashkenazi, non-Ashkenazi, and Arab women aged 19 to 60. The age of menarche appeared to be significantly different for Ashkenazi vs. non-Ashkenazi, while no significant difference was found between Arabs and either of the two Jewish groups. Highly significant differences were found for the length of the menstrual cycle, although this finding should be considered with caution. No significant relationship was found between age of menarche and length of the menstrual cycle.

Riassunto

RIASSUNTO

Lo sviluppo sessuale può essere influenzato da fattori geografici (temperatura, umidità, altitudine, illuminazione), da fattori socio-economici (nutrizione, condizioni sanitarie, famiglia media), e da fattori genetici (eredità di popolazione e familiare). La maggior parte di questi fattori sono ampiamente collegati fra loro e difficili da isolare.

Uno studio anamnestico è stato condotto in Israele su donne Ashkenazi, non-Ashkenazi ed arabe di 19-60 anni. L'età del menarca è risultata significativamente diversa fra Ashkenazi e non-Ashkenazi, mentre fra le donne arabe e quelle dell'uno o dell'altro dei due gruppi ebrei non è stata riscontrata alcuna differenza significativa. Differenze molto significative sono state riscontrate per la durata del ciclo mestruale, ma questa osservazione dovrebbe essere considerata con cautela. Tra età del menarca e durata del ciclo mestruale non è stata riscontrata alcuna relazione significativa.

Résumé

RÉSUMÉ

Le développement sexuel peut être influencé par des facteurs géographiques (température, humidité, altitude, lumière), par des facteurs socio-économiques (nutrition, santé publique, famille moyenne), et par des facteurs génétiques (hérédité de population et familiale). La plupart de ces facteurs sont largement interreliés et donc difficiles à identifier.

Une étude anamnéstique a été conduite en Israel sur des femmes Ashkenazi, non-Ashkenazi et arabes âgées de 19-60 ans. L'âge du ménarche est significativement différente entre Ashkenazi et non-Ashkenazi, tandis que aucune différence significative ne fut remarquée entre arabes et l'un ou l'autre des deux groupes juifs. Des différences très significatives furent remarquées pour la durée du cycle menstruel, mais cette observation devrait être considérée avec prudence. Aucune relation significative ne fut remarquée entre âge du ménarche et durée du cycle menstruel.

Zusammenfassung

ZUSAMMENFASSUNG

Mehrere Faktoren können die Geschlechtsentwicklung beeinflussen: geographische Faktoren wie Temperatur, Feuchtigkeit, Höhenlage, Lichtverhältnisse; sozialökonomische Faktoren wie Ernährung, hygienische Verhältnisse, Durchschnittskinderzahl und Erbfaktoren, d.h. Bevölkerungs- und Familienerblichkeit.

Bei aschkenasischen, nicht-aschkcnasischen und arabischen Frauen im Alter von 19-60 J. wurden die Anamnesen aufgenommen. Dabei erschien das Menarchealter bei aschkenasischen und nichtaschkenasischen Frauen recht verschieden, während zwischen diesen beiden jüdischen Gruppen und den Araberinnen kein wesentlicher Altersunterschied zu bemerken war. Erhebliche Unterschiede zeigten sich hingegen in Bezug auf die Dauer des Zyklus, doch ist diese Beobachtung nur mit Vorsichtzu betrachten. Zwischen Menarchealter und Zyklusdauer Hess sich keine bedeutende Beziehung feststellen.
