[Differences in intake of food and nutrients between manual and desk workers].

Aim: To compare intake of food and nutrients between manual and desk workers.

Subjects And Methods: Subjects were 28,603 residents (13,432 were male and 15,171 were female) in a city. Using a questionnaire, information on frequencies of consumption of different foodstuffs for one year and the type of employment was collected.

Advanced onset of menarche and higher bone mineral density depending on vitamin D receptor gene polymorphism.

Bone mineral density (BMD) at distal forearm, and weight and height of healthy Japanese girls aged 18-19 years were measured and their age at menarche was obtained through a questionnaire. A statistically significant association was found between BMD at distal radius and vitamin D receptor (VDR) gene polymorphism at the ApaI site. The age at menarche in the population with Aa genotype was significantly earlier than that in the aa population.
