Is digit ratio (2D): (4D) associated with a religious profession? An exploratory study on male Polish seminary students
Human females demonstrate higher religiosity than men in populations. Digit ratio (2D:4D), being a putative indicator of prenatal testosterone, is associated in varying degrees with characters that show sexual dimorphism. A small number of studies have indicated that religiosity may be associated with the biological basis of sex differences in humans. The objective of the present study was to ascertain whether 2D:4D in religiously oriented semina…

Impact of normal weight obesity on fundamental motor skills in pre-school children aged 3 to 6 years
centile of the MABC-2 norm. These findings are strongly alarming since indices like BMI are not able to identify normal weight obese individual. We recommend verifying real portion of normal weight obese children as they are probably in higher risk of health and motor problems than overweight and obese population due to their low lean mass.
Post-migration adaptation and age at menarche in the second generation of migrants
Age at menarche is one of the most important measures of sexual maturation in girls. Since it has a high level of ecosensitivity, early environmental stress may trigger early puberty. One of these stress factors may be parental stress caused by the change of living conditions related to migration and adaptation to the new environment. Therefore, the aim of this study was to investigate the relationship between parental migration status and the ti…
Sibling Composition and Household Room Sharing Are Associated with Menarcheal Status among Rural Bengalee Girls of West Bengal, India
