  1. Vitamin D deficiency in homebound elderly persons.

    Article - En anglais

    Objective

    - To assess the vitamin D status in homebound, community-dwelling elderly persons ; sunlight-deprived elderly nursing home residents ; and healthy, ambulatory elderly persons.

    Design

    - A cohort analytic study.

    Participants

    - Of 244 subjects at least 65 years old, 116 subjects (85 women and 31 men) had been confined indoors for at least 6 months, either in private dwellings in the community (the Hopkins Elder Housecall Program) or in a teaching nursing home (The Johns Hopkins Geriatrics Center).

    The 128 control subjects, a healthy ambulatory group, came from the Baltimore Longitudinal Study on Aging.

    All subjects were free of diseases or medications that might interfere with their vitamin D status.

    Main Outcome Measures

    - Serum levels of 25-hydroxyvitamin D (25-OHD) and 1,25-dihydroxyvitamin D (1,25-[OH]2D) were measured in all subjects.

    In a subgroup of 80 subjects, serum levels of intact parathyroid hormone (PTH), ionized calcium, and osteocalcin and intake of vitamin D (through 3-day food records) were assessed.
