This study examined the factor structure of the Centers for Epidemiologic Studies Depression Scale (CES-D) in a sample of 40,403 African American women participating in the Black Women's Health Study (BWHS). To examine within group differences in the structural characteristics of the CES-D, women were stratified by age (< 60 vs. > or = 60 years). Confirmatory factor analysis indicated that a four-factor solution was a good fit for the data in both groups. The four factors extracted (depressed, somatic, positive, and interpersonal) matched findings from previous studies in other populations. Although item loadings were identical for 19 of 20 items, when equality restrictions were placed on factor loadings, the factors were not shown to be equivalent across groups. The only observed difference in item loadings was that the item "people disliked me" loaded higher on the interpersonal factor for younger women than older women. The variance/covariance matrix differed between groups. The correlations between the depressed and somatic factors were identical for the two age groups. However, correlations among the other factors were weaker among older women. We conclude that four-factor structure of the CES-D is supported for African American women, but the relationships among the factors vary with age. 相似文献

PROBLEM: Menstrual disorders, reduced fertility and sexual problems seem to be more frequent in women with epilepsy than in the general population. Most investigations concerning menstrual disturbances in epilepsy patients, however, are small and based on selected materials. We therefore wanted to investigate the frequency of menstrual disturbances in a large, unselected population of epilepsy patients. METHODS: A retrospective, questionnaire study of a cohort of female outpatients, aged 18-45 was conducted. Each patient chose a close female friend who served as control, to optimise matching regarding age and lifestyle. RESULTS: Answers were received from 265 patients and 142 controls. Menstrual disturbances were more frequent in patients with epilepsy (48.0%) than in controls (30.7%) (P=0.004). Menstrual disturbances were more frequent in patients on polytherapy versus monotherapy (P=0.049) and more frequent in patients with high seizure frequency (>5seizures/year) compared to patients with a lower seizure frequency or those seizure free (P=0.006). The frequency of menstrual disturbances was higher in patients on valproate compared to carbamazepine monotherapy (P=0.045). CONCLUSION: This investigation confirms that women with epilepsy have an increased frequency of menstrual disturbances compared to women without epilepsy. In women with high seizure frequency and in those on polytherapy, the frequency of menstrual disturbances are further increased. The highest frequency of menstrual disturbances occurred in women using valproate. 相似文献

Although favorable effects of débridement with chondrectomy and drilling or abrasion have been reported in treating of cartilage lesions in the knee joint; however, in most cases an additional intervention is generally performed during arthroscopy. We studied 53 consecutive patients with solitary chondral lesions in the weight-bearing part of the knee and treated 86 cartilage lesions by arthroscopic débridement, including a detailed removal of damaged or undermined cartilage. We evaluated the postoperative course by questionnaire (mean follow-up 6.5 years, response rate 83%). All patients reported a positive effect of chondrectomy: 69% considered the knee considerably better or cured and 77% regarded the effect as permanent. There was no complication of the arthroscopies performed, and no patient noted any deterioration in the condition. We therefore recommend routine chondrectomy of cartilage lesions when these are found during an arthroscopy. 相似文献

Abstract – For the objective measurement of oral mucosal dryness or moisture, a device registering oral mucosal surface slide friction has been developed. Two prototypes, Probe I and Probe II, have been tested. Probe I was constructed for initial testing of the method and was based on easily accessible electrical components. Probe I was computerized and developed for more accurate registration and also for easy handling. Reliability and validity tests were carried out on Probe I as well as on Probe II. In repeated in vitro measurements, the probes showed good reproducibility. Validity was assessed on healthy subjects injected with methylscopolamine nitrate submucosally in the labial sulcus. All subjects experienced a pronounced oral mucosal dryness within half an hour. Registration with the surface slide friction device showed maximum friction values 1-2 h after injection. These reliability and validity tests gave good results for both Probe I and Probe II, but Probe II had several practical advantages over Probe I. Both probes were considerably more sensitive to changes of the oral mucosal surface than the previously used simple friction test using the back of a mouth mirror. 相似文献

Persistence in ranks (tracking) for blood pressure and anthropometric measures over a one year period was examined in 208 Nigerian children (age 6-17 years). Systolic blood pressure tracked better than diastolic blood pressure (r = 0.52 to 0.72) and r = 0.25 to 0.55, respectively). For systolic blood pressure, 56.5%-70.6% of the Nigerian children remained in the top tertile after one year compared with 45.5%-69.2% for diastolic blood pressure. Weight showed the strongest correlation over the one year period (r = 0.88 to 0.97), whereas skinfolds demonstrated the weakest association (r = 0.54 to 0.82). The association between anthropometric measures at baseline and blood pressure one year later revealed for both males and females that height and weight were positively and significantly correlated with blood pressure. 相似文献
