In a microbicide safety and effectiveness trial (HPTN 035) in Malawi, 585 women completed the same questionnaire through a face-to-face interview (FTFI) and an audio computer-assisted self-interview (ACASI). Concordance between FTFI and ACASI responses ranged from 72.0 % for frequency of sex in the past week to 95.2 % for anal intercourse (AI) in the past 3 months. Reported gel and condom use at last sex act were marginally lower with ACASI than FTFI (73.5 % vs. 77.2 %, p = 0.11 and 60.9 % vs. 65.5 %, p = 0.05, respectively). More women reported AI with ACASI than FTFI (5.0 % vs. 0.2 %, p < 0.001). Analyses of consistency of responses within ACASI revealed that 15.0 % of participants in the condom-only arm and 28.7 % in the gel arm provided at least one discrepant answer regarding total sex acts and sex acts where condom and gel were used (19.2 % reported one inconsistent answer, 8.1 % reported two inconsistent answers, and 1.4 % reported three inconsistent answers). While ACASI may provide more accurate assessments of sensitive behaviors in HIV prevention trials, it also results in a high level of internally inconsistent responses. 相似文献

Between May and October 2000, the Regional Health Office of Kolda Region in the south of Senegal, West Africa, reported an epidemic of an unknown illness characterized by thoracic pain, dyspnea and edemas of limb and face. The epidemic covered a radius of approximately 40 km (24 miles) between the districts of Kolda and Sedhiou in Kolda Region. Cases were mostly men whose age ranged between 12 and 60 years old. Investigation revealed that they had been exposed to pesticides distributed by the government to groundnut farmers. The signs and symptoms suggested intoxication with carbamates, carbofurans, and possibly thiram, contained in the pesticides distributed with the groundnut seeds. Government distribution created an excessive use of pesticides in the farms, and consequently an overexposure of the subjects who handled the seeders, especially young males but also a small proportion of women who worked in the groundnut fields. Many of these subjects, not accustomed to handle pesticides, came to overestimate the quantity of product to fill the seeder. It should be noted that the policy of distribution of pesticides in Senegal, which presents risk of poisoning, was not systematically accompanied by sufficient information on the danger of the products and of certain precautions that should be taken during their use. 相似文献

OBJECTIVES: Activation of latent tuberculosis infection into tuberculosis disease (TB), the primary killer among infectious diseases worldwide, can be prevented with six months of anti-TB medication. A large percentage of adolescents started on medication, however, fail to complete their treatment. The authors developed and tested the effects of innovative educational strategies on infected adolescents at two health centers serving ethnically diverse populations. METHODS: The authors used a randomized experimental four-group design to assess the independent and combined effects of peer counseling and a participant-parent contingency contract intervention. RESULTS: A total of 794 adolescents were recruited into the study, for a 79% participation rate. The overall rate of treatment completion was 79.8%. Self-efficacy for medication-taking behavior at post-test correlated strongly with completion of care (R = 0.367, p = 0.002). Participants randomized to the peer counseling groups demonstrated significantly greater improvements in self-efficacy and mastery than the usual care control group. Based on the study results, continuing education seminars and workshops were implemented for TB control staff at the two health clinics and for all TB Control Division staff at the Los Angeles County Health Department. Educational materials and a training manual for enhancing completion of treatment of latent TB infection through tailored educational approaches were developed and disseminated to the clinics. CONCLUSIONS: Health education and incentives are helpful adjuncts to the completion of treatment for latent tuberculosis infection in adolescents. 相似文献

SETTING: Two health clinics in Los Angeles County, California. OBJECTIVE: To identify factors associated with completion of care among foreign-born adolescents treated for latent tuberculosis infection (LTBI). DESIGN: A total of 766 low-income adolescents (79% participation rate), including 610 foreign-born, were recruited. In prospective face-to-face interviews, data were obtained on socio-demographic and lifestyle characteristics, psychosocial factors and clinic-related variables. Medical chart data were abstracted regarding clinic appointment keeping and completion of treatment. Univariate and multivariate logistic regression analyses were performed to identify factors associated with completion of care. RESULTS: Foreign-born adolescents were more likely to complete care than US-born adolescents, with 82% completion of care rate. In logistic regression analyses after controlling for age, medication taking behavior (OR 1.26, 95%CI 1.15-1.39), living with both parents (OR 1.74, 95%CI 1.02-2.97), sexual intercourse (OR 0.66, 95%CI 0.36-1.19) and speaking mostly or only English with parents (OR 0.39, 95%CI 0.15-1.03) were independently associated with completion of care. CONCLUSION: These findings contribute to our understanding of the factors that may explain why some adolescents complete care whereas others do not. They provide supportive evidence that tailored intervention programs should be developed to support the screening and completion of treatment of foreign-born adolescents. 相似文献
