DAMMAM, Saudi ArabiaOnce a month, Nayla says, she writes a letter to Oprah Winfrey.

A young Saudi homemaker who covers her face in public might not seem to have much in common with an American talk show host whose image is known to millions. Like many women in this conservative desert kingdom, Nayla does not usually socialize with people outside her extended family, and she never leaves her house unless chaperoned by her husband.

Ms. Winfrey has not answered the letters. But Nayla says she is still hoping.

“I feel that Oprah truly understands me,” said Nayla, who, like many of the women interviewed, would not let her full name be used. “She gives me energy and hope for my life. Sometimes I think that she is the only person in the world who knows how I feel.”

Nayla is not the only Saudi woman to feel a special connection to the American media mogul. When “The Oprah Winfrey Show” was first broadcast in Saudi Arabia in November 2004 on a Dubai-based satellite channel, it became an immediate sensation among young Saudi women. Within months, it had become the highest-rated English-language program among women 25 and younger, an age group that makes up about a third of Saudi Arabia’s population.

In a country where the sexes are rigorously separated, where topics like sex and race are rarely discussed openly and where a strict code of public morality is enforced by religious police called hai’a, Ms. Winfrey provides many young Saudi women with new ways of thinking about the way local taboos affect their lives  as well as about a variety of issues including childhood sexual abuse and coping with marital strife  without striking them, or Saudi Arabia’s ruling authorities, as subversive.
