A part of a larger study of the health behaviors of adolescent women, this investigation examined health-promoting behaviors and the influence of cognitive, social, and environmental factors on these health-promoting behaviors of rural adolescent women. The sample consisted of 128 rural African-American and white adolescent women. Forty-four percent of the variance in health-promoting behavior of this sample was explained by five variables: self-image, problem solving, mother's education, employment status, and family structure. Self-image was the most salient predictor of health-promoting behavior, explaining 33% of the variance. 相似文献

Oxidative stress is believed to play an important role in the development of vascular complications associated with diabetes mellitus. In this study, we examined the efficacy of long-term treatment with the antioxidant, N-acetylcysteine, in preventing the development of defective endothelium-dependent relaxation in streptozotocin-induced, Sprague-Dawley diabetic rats. At 48 h after injection of streptozotocin, a portion of diabetic rats received 250 mg/L N-acetylcysteine in drinking water for a total duration of 8 weeks. Oral administration did not alter the increase in blood glucose or the reduction in serum insulin but did modestly reduce total glycosylated hemoglobin. In precontracted thoracic aortic rings suspended in isolated tissue baths, endothelium-dependent relaxation to acetylcholine was impaired in diabetic rings compared with control rings. Endothelium-independent relaxation to nitroglycerin was unaltered. Long-term oral administration of N-acetylcysteine did not alter responses to nitroglycerin but completely prevented the defective relaxation to acetylcholine. These studies indicate a dissociation between glycemic control and correction of endothelial dysfunction and suggest that long-term exposure to reactive oxygen subsequent to diabetes rather than hyperglycemia per se is responsible for the development of endothelial dysfunction in diabetes mellitus. 相似文献

Studied the presence and magnitude of menstrual-cycle-related mood changes using standardized measures of depression and anxiety. 158 females aged 15–16 yrs completed the Menstrual Distress Questionnaire and reported the actual date of onset of their next 2 menstrual periods. These Ss and their male classmates were later given the Depression Adjective Check List, Forms A and D, and the State-Trait Anxiety Inventory twice, 2 wks apart, in an unrelated classroom setting. This study assessed the magnitude of anxiety and depression experienced by the 29 Ss who were tested within 4 days preceding the onset of menstruation and the 23 Ss who were tested during the first 4 days of menstruation. Premenstrual and menstrual test scores were compared with those obtained during the intermenstrual phase of the cycle. No significant differences in mood attributable to cycle phase were found. A control group of males also showed no significant difference in mood. Adolescent women appear to be different from women over 30 who have been reported to show significantly increased state anxiety and depression during the premenstrual phase of the menstrual cycle.

Discusses the stresses of unwanted pregnancy for women, their partners and families, and health professionals. Psychologists are considered capable of reducing the likelihood of unwanted pregnancy as well as contributing to a constructive resolution of the crisis. Factors that are often associated with contraceptive use and nonuse are highlighted. It is also shown that socialization in traditional sex roles contributes to ineffective contraceptive protection. Problems associated with the resolution of unwanted pregnancy are presented, such as resentment toward the child, the sense of loss for the adopted child or the aborted fetus, and depression.

Vascular endothelial growth factor (VEGF) is an endothelial cell-specific angiogenic and permeability-inducing factor that has been implicated in the pathogenesis of diabetic retinopathy. In the present study, the localization and magnitude of VEGF, VEGF receptor-1 (VEGFR-1), and VEGF receptor-2 (VEGFR-2) gene expression were examined in the eye of streptozotocin-induced diabetic rats using quantitative in situ hybridization. VEGF protein was also examined by immunohistochemistry. Abundant VEGF mRNA and protein were present in the retinae of control rats. In the retinae of diabetic rats, VEGF gene expression was increased compared with control animals (p = 0.001). The increase in VEGF mRNA was noted in the ganglion cell layer and inner nuclear layer but not in the pigment epithelium of the retina. VEGF was also detected in blood vessels, ciliary body, and lens epithelium in both control and diabetic rats. The distributions of VEGFR-1 and VEGFR-2 were similar in both control and diabetic rats. VEGFR-1 mRNA was present beneath the inner limiting membrane and in the ganglion cell layer, inner nuclear layer, outer plexiform layer, and outer limiting membrane of the retina; it was also detected in blood vessels, the ciliary body, and the cornea. The magnitude and distribution of ocular VEGFR-1 mRNA were not affected by experimental diabetes. Expression of VEGFR-2 mRNA was noted in the inner nuclear layer and pigment epithelium of the retina and in blood vessels. An increase in VEGFR-2 mRNA in the diabetic retina was restricted to the inner nuclear layer. The presence of VEGF and its receptors in the control retina suggests a physiologic role for VEGF within the eye. The changes in retinal expression of VEGF and VEGFR-2 in association with diabetes suggest a role for this pathway in diabetic retinopathy. 相似文献

This longitudinal study of 137 female high school seniors investigated the relationship of attachment cognitions, current psychological functioning, and psychological functioning 12 months later. Attachment cognitions, assessed with the Revised Adult Attachment Scale and the Inventory of Parent and Peer Attachment, were significantly associated with current symptomatology. The Revised Adult Attachment Scale, in interaction with initial symptomatology, predicted depression, substance abuse, eating disorders, and personality disorders 12 months later. The Inventory of Parent and Peer Attachment parent subscales predicted eating disorder and personality disorder symptomatology, whereas the peer subscales predicted substance abuse, eating disorder, and personality disorder symptomatology. 相似文献

Although some research suggests that sexual orientation is a stable, early appearing trait, interviews with 89 young sexual-minority women revealed that a majority of women failed to report at least one of the following: childhood indicators of sexual orientation, stability in same-sex attractions, or awareness of same-sex attractions prior to the conscious process of sexual questioning. Lesbians were not more likely to report these experiences than bisexuals, although they reported significantly greater same-sex attractions. Consistent with studies on older cohorts, few young women reported exclusive same-sex attractions. These findings suggest that recollected consistency among prior and current behavior, ideation, and attractions are not systematically associated with sexual orientation among contemporary young women. 相似文献

OBJECTIVE: To describe the occurrence of endometriosis in monozygotic twins. DESIGN: Postal questionnaire plus confirmation of disease status. SETTING: Twins were recruited via the American Endometriosis Association and the National Endometriosis Society of Great Britain and via British gynecologists. RESULT(S): Fourteen twin pairs were concordant for endometriosis, and two were discordant. Nine pairs of twins had moderate-severe endometriosis. CONCLUSION(S): These findings contribute to the growing body of literature that suggests endometriosis has a genetic basis. 相似文献

This qualitative study examined the perceived career options of 10 White adolescent young women who experienced social class privilege in their families of origin. The model of contextual privilege and career selection for adolescent White women emerged from the data, and it describes how social class privilege, gender, achievement expectations, experiences, and verbal messages may influence perceived occupational possibilities. The model includes 4 categorical groups: (a) Social Class Identity and Perceptions, (b) Shared Perceptions of Achievement and Expectations, (c) Exposure, and (d) Evaluating Career Options. The findings suggest that social class privilege contributes to the perception of numerous career options. Yet it also contributes to a process wherein participants unintentionally limit their career aspirations to a very narrow range of options.

Depression in adolescent girls may result in negative consequences in young adulthood. The Center for Epidemiologic Studies Depression Scale (CES-D) was administered to 1,727 Black and White girls ages 16 to 18 years who participated in the National Heart, Lung, and Blood Institute's Growth and Health Study. Three years later, women in the depressed groups were more likely to be current smokers, had attained a lower level of education, and reported lower self-worth relative to the nondepressed group. Body dissatisfaction, eating concerns, and loneliness were greater in the depressed groups. Relative to Black women, White women who were moderately depressed during adolescence reported more health care services utilization in young adulthood. Prevention efforts for depressed adolescents should be broadly focused to improve young adult outcomes. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

The authors examined C. Hammen's (1991) model of stress generation in depression and the role of interpersonal problem-solving strategies (IPS) in the stress generation process in a longitudinal sample of 140 young women who entered the study at ages 17–28. Structural equation modeling was used to test a model in which IPS and subsequent interpersonal stress mediated the relationship between initial and later depressive symptoms. Results supported the main prediction of the stress generation model: Interpersonal stress mediated the relationship between initial and later depressive symptoms. In addition, IPS predicted interpersonal stress. However, no association was found between depressive symptoms and IPS. An alternative model in which IPS moderated the relationship between stress and depressive symptoms was tested; it was not supported. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Expanded on R. E. Fassinger's (see record 1990-21225-001) model of career choice in college women by testing 2 causal models of career choice and orientation with high school women. Ss were 409 adolescent women enrolled in their last year of high school in an all-female private liberal arts high school in a large Midwestern city. Structural equation modeling analyses suggested that the career orientation and career choice of adolescent women were predicted by ability, agentic characteristics, gender role attitudes, and relationship with mother. Young women who possessed liberal gender role attitudes, were instrumental and efficacious with regard to math and careers, and exhibited moderate degrees of attachment and independence from their mothers tended to value their career pursuits. Adolescent women who selected nontraditional and prestigious careers showed high ability and strong agentic characteristics. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

The following is an account of a case of Endometriosis of the Ileum in an 11 year old girl. The patient's first menstruation was accompanied by pain localized in the lower right abdominal quadrant. Her second menstruation was again accompanied by pain. During an explorative laparotomy, a tumorous mass was found in the wall of the ileum 50--60 cm proximal to Valvula Ileocecalis. The tumor was seven mm in diameter, having a fibrous thickening in the surrounding wall. A resection of this segment of intensine was performed. Histological findings confirmed an endometriosis of the Ileum of a polypoidal infiltrative type. The patient encountered no difficulties postoperatively. Proceeding menstruations were painless, which is indicative of an isolated endometriosis of the ileum. 相似文献

The effects of depression and Axis I comorbidity on subsequent self-generated life stress were examined in a longitudinal sample of 134 late adolescent women. The results indicated that specific forms of psychopathology constitute a risk factor for future self-generated episodic stress, even when controlling for prior chronic stress. Comorbid depression had a particularly salient effect in the prediction of stress related to interpersonal conflicts. The effects of family psychopathology and sociotropy were mediated through participant psychiatric status, whereas autonomy made an independent contribution to the prediction of episodic stress. These results support C. Hammen's (1991) stress generation model in a community sample, demonstrating how individuals with depression play a role in the creation of stress, and also refine prior work by showing that only the comorbid form of depression is associated with subsequent conflict-related stress.

BACKGROUND: Multiple primary neoplasms have been reported 4% to 26% of patients with a squamous cell carcinoma (SCC) of the head and neck. The vast majority of these second primaries are SCC and occur in the upper aerodigestive tract; however, head and neck SCC patients are also at higher risk for nonepidermoid neoplasms at any site. Reticuloendothelial malignancies (REM) have been reported in many patients that have SCC of the head and neck as well. METHODS: Retrospective case series of 5 advanced cases of SCC of the head and neck with synchronous REM. RESULTS: There was 40% mortality with 19.4 months mean follow-up. Fifty percent of the case had simultaneous cervical involvement with both processes. CONCLUSION: REM can occur simultaneously with SCC of the head and neck and confound staging of nodal status. Head and neck SCC patients are at increased risk for REM secondary to age and treatment factors. 相似文献

Endometriosis in postoperative abdominal wall scar after cesarean section is rarely observed. In professional literature, only single cases are reported. The author presented 27 cases of this diseases. The women were treated in the Gynaecology and obstetrics Department of Medical School in Lód?, in 1985-1994. Because of the small response to pharmacological treatment, the treatment of choice was surgical of the lesion. In the article, the literature concerning the disease is presented. 相似文献
