CONTEXT: Rapid repeat pregnancy (RRP) among adolescents, usually defined as pregnancy onset within 12-24 months of the previous pregnancy outcome, has frequently been the target of public health interventions, due to the exacerbation of negative consequences associated with recurrent adolescent pregnancy (and more specifically with childbearing). OBJECTIVE: To examine what, if any, relationship exists between RRP and the experience of interpersonal violence and abuse among low-income adolescents at one semi-urban health center. DESIGN: Case-control study using retrospective chart review. PARTICIPANTS AND SETTING: 100 women aged 13-21 who received prenatal care at one independent nonprofit health center that serves adolescents and their children from June 1994 through June 1996. MAIN OUTCOME MEASURES: Number and timing of pregnancies, occurrence of physical or sexual abuse; other psychosocial risk factors were evaluated. RESULTS: In this population, the experience of any form of physical or sexual violence during the study interval was associated with RRP within 12 months (p = 0.01, OR = 3.46) and 18 months (p = 0.013, OR = 4.29). Other previously reported predictors of RRP, including family stress, financial stress, and other environmental stressors did not reach statistical significance at either 12 months or 18 months in this sample. Of additional note, young women who experienced any form of abuse during the 12-month study interval were substantially more likely to miscarry than were their nonabused peers, and spontaneous abortion was also very strongly associated with RRP (p < 0.00001; OR = 22.6). CONCLUSIONS: The experience of interpersonal violence is correlated with rapid repeat pregnancy among low-income adolescents. This study strongly suggests a need for both extensive screening for partner and family violence among pregnant and postpartum adolescents, and follow-up safety planning support in combination with family planning interventions. 相似文献

In 1983, a Down's Syndrome male (I.Q. 72) AB who resided in a community residence was charged by local police with Exposing his genitalia, as a result of an incident of exhibitionism. Upon investigation by the New Jersey Division of Mental Retardation (a State of New Jersey Agency now named the New Jersey Division of Developmental Disabilities), it was found that AB had a constellation of inappropriate sexual and social behaviors. A treatment plan was designed by a State Psychologist, a private Psychologist, a State Special Educator, a State Social Worker, and residential staff, with the full cooperation of AB's parents. The treatment approach combined traditional psychotherapy, a token economy plan, and vigorous social skills training. AB has been followed for 7 years and the treatment plan has been modified a number of times, as AB's behavior has continued to improve. Over the 7 years, AB has not had any more arrests on sexual charges and his overall social behavior has shown marked improvement. 相似文献

During a school-based survey, middle and high school students (n = 1536) reported on their nonprescribed, lifetime use of asthma inhalers. Approximately 15% of 8th and 9th graders reported using nonprescribed asthma inhalers; the odds for this behavior were significantly higher for these students (2.25 and 2.30, respectively) and the nonprescribed use of asthma inhalers was significantly associated with higher rates of other drug use. 相似文献

This study sought to determine clinical predictors of alcohol relapse during recurrence of major depression. The total sample included 2,820 adults with a history of alcohol dependence who had a comorbid current episode of major depression. Twenty-six percent had a relapse of alcohol dependence. Relapsers were more likely to be male, single, less educated, and younger than non-relapsers. Early onset alcohol dependence and past year drug use disorder significantly increased the likelihood of relapse. Early onset substance use dependence is a more powerful predictor of alcohol relapse than early onset major depression. 相似文献

A total of 41 questionnaires were returned from 64 respondents who consented to receive a questionnaire through the mail. Almost all valued the opportunity to receive consultation to address their fertility concerns and discuss fertility preservation options. Psychological stress, time pressure, and costs were identified as main factors affecting respondents’ decision to proceed with in-vitro fertilization to cryopreserve oocytes or embryos. About one third indicated that the discussion of fertility matters was initiated by themselves, their friends, and families rather than their health care providers. The findings have identified several major barriers encountered by female cancer patients when seeking fertility preservation services. 相似文献
