This past winter, Ms. Sehgal surveyed 198 M-A students in grades 9-12 and found that just 38 percent of the students took enough calcium to meet daily requirements. The survey group was made up of 55 percent boys and 45 percent girls, with 20 percent of the girls meeting the calcium requirement and 52 percent of the boys, she said.
Calcium intake drops as the teen years go by, Ms. Sehgal said in an interview. By 18, "barely anybody takes enough calcium," she said.
"It's, like, crucial to take that calcium during adolescence"
Women, she said, are four times more likely than men to develop osteoporosis because of lower female bone mass generally and drops in estrogen levels after menopause.
Adequate calcium intake as a teen is a big deal. "It's, like, crucial to take that calcium during adolescence," she said, adding that in her survey, 85 percent of the students also knew that to be true.
Why does calcium intake drop off? Ms. Sehgal didn't have an answer, but guessed that teens are learning to make their own decisions and may be giving less credence to the views of their parents.
Ms. Sehgal's father is a research physician at Stanford University hospital, she said, while her mother is a retired physician.
The contest was sponsored by the Robert Wood Johnson Foundation and administered by the College Board.
Local students have been well represented in this annual contest lately. In 2008, Maya Mathur of Woodside won a $35,000 scholarship, and in 2007, M-A grad Mio Frisk won a $15,000 scholarship.
