The public health approach to health problems provides a strong framework and rationale for developing and implementing suicide prevention programs. This approach consists of health-event surveillance to describe the problem, epidemiologic analysis to identify risk factors, the design and evaluation of interventions, and the implementation of prevention programs. The application of each of these components to suicide prevention is reviewed. Suggestions for improving surveillance include encouraging the use of appropriate coding, reviewing suicide statistics at the local level, collecting more etiologically useful information, and placing greater emphasis on analysis of morbidity data. For epidemiologic analysis, greater use could be made of observational studies, and uniform definitions and measures should be developed and adopted. Efforts to develop interventions must include evaluating both the process and the outcome. Finally, community suicide prevention programs should include more than one strategy and, where appropriate, should be strongly linked with the community's mental health resources. With adequate planning, coordination, and resources, and the public health approach can help reduce the emotional and economic costs imposed on society by suicide and suicidal behavior.  相似文献

P hysical illness has been studied as a risk factor for suicidal behavior, but little is known about this relationship among younger persons. We conducted a population‐based, case‐control study in Houston, Texas, from November 1992 through September 1995. The final sample consisted of 153 case‐ and 513 control‐subjects aged 13 to 34 years. Case patients were identified at hospital emergency departments and met criteria for a nearly lethal suicide attempt. Control subjects were recruited via a random‐digit‐dial telephone survey. Case patients were more likely than controls to report having any serious medical conditions (crude OR = 3.23; 95% CI = 2.12–4.91). After controlling for age, race/ethnicity, alcoholism, depression, and hopelessness, the adjusted odds ratio for men was 4.76 (95% CI = 1.87–12.17), whereas the adjusted odds ratio for women was 1.60 (95% CI‐0.62–4.17), suggesting that young men with medical conditions are at increased risk for nearly lethal suicide attempts. Increased efforts to identify and appropriately refer these patients are needed.  相似文献

Pornography is a lucrative business. Increasingly, women have participated in both its production, direction, and consumption. This study investigated how the content in popular pornographic videos created by female directors differs from that of their male counterparts. We conducted a quantitative analysis of 122 randomly selected scenes from 44 top-renting adult videos in 2005 (half male- and half female-directed). Findings revealed that all films shared similar depictions: Verbal and physical aggression was common, women were the primary targets of aggression, and negative responses to aggression were extremely rare. Compared to male-directed films, female-directed films were significantly more likely to portray women-only scenes and sexual acts. Even when controlling for main characters' gender, female-directed films showed significantly more female perpetrators aggressing against female targets and significantly more depictions of women as perpetrators of aggression. We highlight the importance of economic forces, rather than director gender, in dictating the content of popular pornography.  相似文献

The Self-inflicted Injury Severity Form (SIISF) was developed as an epidemiological research tool for identifying individuals in hospital emergency departments who have life-threatening self-inflicted injuries. Data were collected from 715 patients with self-inflicted injuries in two large hospitals. In 295 of these cases, a second set of data was independently collected for assessment of interrater reliability. Validity was assessed by comparing the SIISF results with simultaneously collected Risk—Rescue Ratings. Assessment of interrater reliability found that only 2.4% of physicians disagreed on the suicide method used. The kappa statistic for method used was .94, indicating excellent agreement. The SIISF was found to distinguish between severe and less severe injuries. Thus, it appears to provide a simple method to distinguish patients who have life-threatening self-inflicted injuries.  相似文献

Objective: Interpersonal relationships are important predictors of health outcomes and interpersonal influences on behaviours may be key mechanisms underlying such effects. Most health behaviour theories focus on intrapersonal factors and may not adequately account for interpersonal influences. We evaluate a dyadic extension of the Theory of Planned Behaviour by examining whether parent and adolescent characteristics (attitudes, subjective norms, perceived behavioural control and intentions) are associated with not only their own but also each other’s intentions/behaviours.

Design: Using the Actor-Partner Interdependence Model, we analyse responses from 1717 parent-adolescent dyads from the Family Life, Activity, Sun, Health, and Eating study.

Main Outcome Measures: Adolescents/parents completed self-reports of their fruit and vegetable consumption, junk food and sugary drinks consumption, engagement in physical activity, and engagement in screen time sedentary behaviours.

Results: Parent/adolescent characteristics are associated with each other’s health-relevant intentions/behaviours above the effects of individuals’ own characteristics on their own behaviours. Parent/adolescent characteristics covary with each other’s outcomes with similar strength, but parent characteristics more strongly relate to adolescent intentions, whereas adolescent characteristics more strongly relate to parent behaviours.

Conclusions: Parents and adolescents may bidirectionally influence each other’s health intentions/behaviours. This highlights the importance of dyadic models of health behaviour and suggests intervention targets.  相似文献
