The association between adolescent spirituality and voluntary sexual activity.

PURPOSE: The purpose of this study was to describe the spectrum of adolescent spirituality and to determine the association between dimensions of spirituality and voluntary sexual activity (VSA) in adolescents. DESIGN: A sample of 141 consecutive youth aged 11-25 years presenting to an urban, hospital-based adolescent medicine clinic completed a 153-item instrument assessing sociodemographics, psychosocial parameters, and eight specific aspects of spirituality including: (1) religious attendance, (2) religious importance, (3) intrinsic and (4) extrinsic religious motivation, (5) belief in God, (6) belief in divine support, (7) existential aspects of spirituality, and (8) spiritual interconnectedness. Adolescents were also asked about VSA. RESULTS: Sixty-one percent of respondents were African-American and 67.4%, female; mean age was 16.0+/-2.4 years. Adolescent religious attendance was equally distributed across the categories from "none" to "weekly or greater" attendance. Over 90% felt religion was somewhat important in their lives. Over 85% reported belief in God. Fifty-six percent of respondents reported a history of VSA. Greater importance of religion (p = 0.035) and higher spiritual interconnectedness with friends (p = 0.033) were inversely associated with VSA. A multiple logistic regression model including age, gender, race, socioeconomic status, and specific denomination of religious faith, importance of religion, and spiritual interconnectedness found that spiritual interconnectedness with friends (OR = 0.92, 95% CI = 0.85, 0.99) and age (OR = 1.75, 95% CI = 1.34, 2.28) were independent predictors of VSA. CONCLUSIONS: Spirituality is a common facet of adolescents' lives. Younger age and higher spiritual interconnectedness, particularly interconnectedness among spiritual friends, are independently associated with a lower likelihood of VSA.

The CDC25 "Start" gene of Saccharomyces cerevisiae: sequencing of the active C-terminal fragment and regional homologies with rhodopsin and cytochrome P450.

The CDC25 Start gene whose product appears to be required for traversing the Go phase of the cell cycle in Saccharomyces cerevisiae, has been previously cloned (J. Daniel and G. Simchen (1986), Curr Genet 10:643-646). By nucleotide sequencing of an active subclone, we found that only a region of the gene that codes for the C-terminal portion of the CDC25 protein was required for full suppression of the cdc25 mutation. The codon usage in this region indicates a poor translation of the transcript compared to genes encoding abundant proteins. The derived CDC25 protein fragment contains two regions of homology, one with the rhodopsin family, the other with the cytochrome P450 family. Strikingly, these two regions of homology are adjacent on the CDC25 protein. In view of the likely involvement of the CDC25 protein in the regulation of adenylate cyclase activity, a working hypothesis is proposed that accounts for the observed homologies.

Child abuse and accidents in black families: a controlled comparative study.

Families of child abuse and accident victims were evaluated in a study of 402 families with children up to four years of age. Children were matched on a one-to-one basis with a control according to race, socioeconomic status, and age. Socioeconomic factors that play a significant role in imposing undue stress upon many families are identified, and implications for prevention and for practice are offered.
