Sociodemographic characteristics and sexual behavior as risk factors for human papillomavirus infection in Saudi Arabia.

OBJECTIVES: To determine the prevalence and the sociodemographic characteristics and sexual behavior risk factors for human papillomavirus (HPV) infection in a hospital-based cohort of women in Saudi Arabia. METHODS: Cervical specimens and questionnaire data were collected from women attending clinics in Riyadh, Saudi Arabia. Cervical specimens were examined for abnormal cytology using a standard Pap test and for the presence of HPV-DNA using PCR and reverse line blot hybridization tests. RESULTS: Approximately 73% of the 400 women tested were Saudi nationals. Nearly 50% were under 40 years old (range 22-80 years, mean±standard deviation 41.20±10.43 years). Approximately 17% of the women were HPV-positive. The most commonly detected HPV types were HPV-18 (34%) and HPV-16 (19%), with multiple infections detected in 10% of positive specimens. Multivariate analyses revealed that smoking and multiple partners were significant risk factors for HPV infection (p<0.01). CONCLUSIONS: Because of societal challenges and an unsubstantiated assumption of low HPV prevalence, few studies have examined sociodemographic characteristics or sexual behaviors associated with HPV in Saudi women. However, a high prevalence of HPV infection was found, with smoking and multiple partners as significant risk factors, in this hospital-based cohort of predominantly Saudi women.

Rural-urban differences in the distribution of parent-reported risk factors for substance use among young adolescents.

PURPOSE: We examined rural-urban differences in cumulative risk for youth substance use. A recent report [National Center on Addiction and Substance Abuse (CASA) 2000] found that the rural-urban distribution of substance use and known risk factors for substance use differed; in many cases rural youth showed higher levels of use, as well as higher levels of risk factors. The current investigation, while not directly examining substance use, further examined rural-urban differences in the distribution of risk factors for youth substance use, based on information from parent reports. METHOD: Study 1 data were collected from a random sample of Midwestern parents (n = 339) with a young adolescent between the ages of 11 and 13 years. Study 2 data were collected from a second sample of Midwestern parents (n = 593). RESULTS: Analyses of rural-urban comparisons demonstrated higher levels of cumulative risk among rural youth. An evaluation of the sensitivity of the analysis to rural-urban classification schemes indicated that the findings were robust, but that there was some minor variation in rural-urban differences by classification scheme. IMPLICATIONS: Results contribute to an explanation of findings from earlier reports of rural-urban differences in substance use, and suggest directions for future research on rural-urban distributions of youth risk factors.

Effects of list organization and retrieval cues on children's delayed recall.

Developmental differences in recall were investigated as a function of mode of presentation (blocked vs. random), recall condition (cued vs. noncued), and time of recall (immediate vs. delayed). Ninety-six second graders and 96 fourth graders were the subjects, and the stimuli were 20 pictured items from five categories. Data on three dependent variables (item recall, category recall, and clustering score) were analyzed. Immediate recall was better than delayed recall, the fourth graders' overall performance was superior to that of the second graders, and the blocked presentation of items and the presence of retrieval cues at recall enhanced recall and organization in recall. Furthermore, an analysis of a three-way interaction on two dependent measures indicated that, in the noncued condition, immediate recall was better than delayed recall for children in both grades. However, in the cued condition, the fourth graders performed better during delayed recall than during immediate recall, whereas the second graders did better during immediate recall than during delayed recall.
