Risk factors for juvenile onset recurrent respiratory papillomatosis.

BACKGROUND: Children born to condylomatous mothers are at risk for developing juvenile onset recurrent respiratory papillomatosis (JORRP). We inquired whether the triad of vaginal delivery, being firstborn and maternal age of <20 years are also risk factors for JORRP. METHODS: Data for JORRP and adult onset recurrent respiratory papillomatosis cases were obtained from questionnaires answered by patients or their parents for the Recurrent Respiratory Papillomatosis Foundation. The observed numbers of cesarean births, first order births and births to mothers <20 years old were compared with expected numbers for the same variables, which were computed by distributing the cases by year of birth and then applying to them national annual statistics for the year of birth. In addition observed and expected numbers of first order births to mothers <20 years old were compared with corresponding numbers in mothers 20 years old or older. RESULTS: In JORRP cases the relationships be tween observed and expected numbers of cases were as follows: cesarean births, 4.6-fold less; first order births, 1.6-fold greater; maternal age <20 years old, 2.6-fold greater. All these differences were statistically highly significant. The observed parity effect was mediated to a large extent by maternal age. In contrast there were no significant differences between observed and expected numbers of adult onset recurrent respiratory papillomatosis cases with respect to any of the above variables. CONCLUSIONS: Young primiparous mothers with condylomas are at a high risk for transmission of JORRP to their infants. The option of cesarean delivery should be discussed with a mother who has condyloma at the time of delivery.

First intercourse among young Americans.

In 1979, 50 percent of women aged 15-19 and 70 percent of men aged 17-21 living in metropolitan areas of the United States reported that they had ever had sexual intercourse. The average age at which young women had their first sexual experience was 16.2, compared with 15.7 among the men; women tended to have their first intercourse with a partner nearly three years older than themselves, whereas men had their first intercourse with a partner less than one year older. Blacks generally experienced first coitus at a younger age than did whites. Young women's first coitus generally occurred with someone toward whom the respondent felt a commitment; more than six in 10 young women said they had been going steady with or engaged to their first sexual partner. In contrast, fewer than four in 10 young men said that they had been engaged to or going steady with their first partner, and more than one in three said that they and their first partner had been friends. Young men were more than twice as likely as young women to have had first intercourse with someone they had only recently met. Seventeen percent of the young women and 25 percent of the young men surveyed said that they had planned their first intercourse; women who had been going steady with their first partner were most likely to have planned intercourse, while the young men who had met their first partner shortly before intercourse took place were the most likely to have planned the act.(ABSTRACT TRUNCATED AT 250 WORDS)
