We measured serum 25-hydroxyvitamin D and parathyroid hormoneduring the summer (August through October) in 465 women fromthe village of Nabi-Shit (latitude, 33.5 degrees north) in centralLebanon. We studied a random sample of women, most of whom wereof reproductive age, who were eating a regular Middle Easterndiet, including dairy products.
