Abstract

Occupational injuries are estimated to cause over 300,000 deaths per year worldwide. Many low- and middle-income countries often lack effective injury surveillance systems. We attempted to utilize household surveys to collect occupational injury data to develop more accurate injury incidence data. We undertook a pilot study of this approach in the rural area of Mirsarai, Bangladesh. Surveys were administered to 2,017 males and 120 females. Sixty-five percent were self-employed and over 80% worked in work places with less than six employees; over 60% worked seven days per week. Just over 50% of subjects reported at least one injury at work in the prior year. Incidence of lost-time injuries was 31%. The median number of work days lost was 7. The injury rates were higher than ILO estimates for Bangladesh, perhaps because of our study's focus on a rural population. We recommend expanding to larger and a more representative sample of the Bangladesh working community.  相似文献

This article explores the discrepancies between the vocal public discourse on HIV/AIDS and sexuality as generally encouraged by policy-makers and donor communities in Africa, and the often hushed voices of their target groups: young people in African communities. Based on fieldwork among urban youth in Senegal and Burkina Faso, we describe the silence of young people with regard to HIV/AIDS and sexuality as a social phenomenon, with focus given to family relations, peer relations and gender aspects in partnerships. Drawing on Foucault and Morrell, an inability and unwillingness to speak about HIV/AIDS and sexuality are analysed as a response to an everyday life characterised by uncertainty. This response represents a certain degree of resistance, while it constitutes a major barrier to any HIV/AIDS prevention effort. Finally, we stress that despite great constraints in their everyday lives, young people have some room to manoeuvre and are able to apply some negotiating strategies to reduce sexually-related health risks.  相似文献

The purpose of this paper is to understand how married and cohabiting men and women define risk and to identify the factors that influence risk perceptions in a setting with a high prevalence of HIV infection. A combination of qualitative and quantitative methods was used during a cross-sectional survey conducted among 248 men and 289 women in KwaZulu-Natal, South Africa. Forty in-depth interviews were conducted with sexually-active men and women in the same population. The majority of men and women perceived themselves at risk of HIV infection. Women were more likely than men to report a higher risk of HIV infection. Nearly 46% of women and 28% of men perceived themselves at medium or high risk of HIV infection. The qualitative and quantitative data show that perception of risk of HIV infection was influenced both by a person's own sexual behaviour and a partner's sexual behaviour. Men were significantly more likely to perceive themselves at risk because of their own risky sexual behaviour (P < 0.01). In general, few women reported engaging in risky sexual behaviour. However, women were more likely to report that their partners had other sexual partners. Thus, women were significantly more likely to perceive themselves at risk because of their partner's sexual behaviour (P < 0.05). Also, rural women were significantly more likely than urban women to perceive a high risk of HIV infection (P < 0.05). Prevention programmes have an important role to play in creating awareness of the risk of HIV, especially among men. The belief that they are not at risk of HIV infection may result in their failure to adopt self-protective behaviour.  相似文献

The study estimates the economic burden of HIV and AIDS on households in a Nigerian population. The data derive from a cross-sectional survey of households affected by HIV or AIDS in Ife-Ijesa Zone, Osun State, Nigeria. The sample consisted of 117 purposively selected, consenting adult HIV patients attending a general and teaching hospital. Participants were asked to self-report monetary expenses for HIV-related care, loss of savings, and funeral costs. The data show a significantly sharp drop in the participants' household income as a result of care for HIV-related illnesses, from the time of knowing one's HIV status to the time of illness, among three occupational categories (artisans, civil servants and unemployed; p = 0.02). Mean income among those in the unemployed category fell by 84.1%, income among artisans dropped by 72.6%, and income among civil servants decreased by 44.4%. The monetary loss during the course of HIV-related illnesses was heaviest for the artisan group, followed by the unemployed and the civil servants. Those who had lost a substantial part of their savings to HIV-related care were most numerous among the unemployed, followed by artisans and civil servants. Out of 16 households, 11 (42.3%) had received support from relatives during a funeral ceremony. There was a significant association between the occupational group and working for more hours after illness (χ2 = 9.28, df = 4; p = 0.05). Nearly all orphaned children were distributed to the extended family following the AIDS death of a parent. Among all the occupational groups, borrowing from a cooperative society during the course of HIV-related sickness was the commonest form. The findings add to data showing that despite the extended family support system, adult deaths due to AIDS continue to undermine the viability of sub-Saharan African households.  相似文献

This report describes the implementation and short-term results of a peer group intervention for HIV prevention on the HIV-related attitudes, knowledge and behaviours of primary school teachers in Malawi. The intervention, based on the social-cognitive learning model, took place in 2000 at two teacher training colleges with a distance-learning programme. Primary school teachers attending a final six-week training session before certification volunteered to participate. Group leaders were teachers selected by each group, and after training they facilitated the peer group intervention. The teachers completed a pre-test and post-test questionnaire. The 286 trainee teachers whose pre- and post-test samples could be matched, largely reported positive changes in their HIV-prevention-related knowledge, attitudes, self-efficacy, behaviour change and condom-use intentions. However, at post-test immediately after the intervention they did not show a higher level of perceived-risk, a greater hope that people could change their high-risk sexual behaviour, or greater agreement that persons infected with HIV should be allowed in public places. This research demonstrates the feasibility of an HIV-prevention intervention for primary school teachers during their training. The Malawi Ministry of Education has since made the programme available to over 90 per cent of all trainee teachers through an NGO.  相似文献

This study addressed the hypothesis that dietary supplementation with either gangliosides or choline during the brain growth spurt would enhance short-term spatial memory. Male Long-Evans rats were reared artificially from postnatal days (PD) 5–18 and were fed diets containing either (i) choline chloride 1250 mg/l (CHL), (ii) choline chloride 250 mg/l and GD3 24 mg/l (GNG) or (iii) choline chloride 250 mg/l (STD). A fourth group (SCK) was reared normally. Rats were weaned onto AIN 93G diet and on PD 35 were trained on a cued delayed- matching-to-place version of the Morris water maze. All groups learned to swim to the beacon that indicated the platform position on the first trial; similarly, on the second un-cued trial, the distance swam to reach the platform decreased to the same extent in all groups over the five days of training. The groups also responded in the same way to an increase in delay between the first and second trial from 1 min to 1 h, showing an increase in the distance swam, accompanied by a decrease in the number of direct swims to the platform. Thus, all rats were equally proficient at using spatial short-term memory, regardless of the choline or ganglioside content of the preweaning diet.  相似文献

In advocating HIV prevention, organisations such as loveLife in South Africa have increasingly used the media to encourage communication and influence behaviour change in youth. Our study examined youths' understanding and communication habits surrounding loveLife's extensive 'Get Attitude' print campaign. Intrigued by the ambiguous campaign message, we implemented a questionnaire-based study in three urban KwaZulu-Natal schools to investigate how youth are interpreting the images and to determine whether they would connect the personality-aimed message with HIV prevention. As communication is a focal point of loveLife's strategy, we looked at whether the campaign was successful in fostering discussion and examined what factors contributed to or impeded dialogue. One-hundred-and-eighty-seven Grade 11 students completed the questionnaire, responding to both multiple-choice and free-response questions about the 'Get Attitude' campaign images. Our study was largely exploratory, with the data revealing that the youth did interpret the images as intended by loveLife. While the campaign failed to stimulate discussion for many of the youth, those who did talk about the campaign were more likely to speak to their teachers than to parents or friends.  相似文献

This article describes the effects of a national mass media and community-level stigma-reduction programme in Ghana, in which national and local religious leaders urged their congregations and the general public to have greater compassion for people living with HIV or AIDS (PLHA). Data were collected from men and women living in three regions, first in 2001 (n = 2 746) and again in 2003 (n = 2 926). Attitudes related to a punitive response to PLHA both improved over time and were positively associated with exposure to the programme's campaign, controlling for potential confounding variables. Respondents in the 2003 survey were 20% more likely than respondents in the 2001 survey to be willing to care for an HIV-infected relative in their own household and 40% more likely to believe that an HIV-infected female teacher should be allowed to continue teaching. Overall, respondents exposed to the campaign were 45% more likely than those not exposed to it to be willing to care for a HIV-infected relative, and 43% more likely to believe that an HIV-infected female teacher should be allowed to continue teaching. Respondents exposed to the campaign also had significantly more favourable scores on an attitude scale measuring the belief that HIV-infected individuals should be isolated from others. The results of this evaluation suggest that mass media channels and religious leaders can effectively address HIV-related stigma on a national scale.  相似文献

Large-scale surveys have reported that about 55% of orphans worldwide are adolescents. In Kenya, the majority of HIV-infected adolescents are females. The current study used the anthropological methods of in-depth case studies to analyse how migratory life situations of individual female adolescent orphans in the Luo community of Western Kenya may increase their exposure to HIV. The study shows that the ability of the female adolescent orphans to adopt risk-preventive behaviour in relation to HIV is determined by a range of factors beyond their control of individual sexual behaviour. Although analysis of a single case study limits generalisation of the findings, the results provide insights into the reason for sex differentials in HIV infection rates among adolescents as reported in some large-scale surveys. The paper recommends that HIV prevention strategies for adolescents should examine the specific life situations of female orphans by focusing on the impacts of HIV and AIDS and poverty on the protective role of the family. It also recommends that keeping female adolescent orphans in school or in vocational training can be an effective HIV prevention strategy for them.  相似文献

Misconceptions about how HIV can be transmitted or prevented often prevent individuals from making informed choices and taking appropriate action. The purpose of the research was to explore the socio-demographic and behavioural factors in Botswana that are associated with misconceptions about HIV prevention and transmission. The data used were from the Botswana AIDS Impact Survey II conducted in 2004, which constitutes a nationally representative sample. Results from bivariate and multivariate analyses show that young people, males, the less educated, those who did not use a condom during their last instance of sexual intercourse, and those who believe that nothing can be done to reduce HIV infection are most likely to harbour misconceptions about how HIV can be prevented and transmitted. Since misconceptions may prevent people from making informed choices, intervention programmes aimed at HIV prevention should aim to dispel misconceptions about HIV and AIDS as an important part of their strategy. Targeted HIV prevention and education programmes are needed in an effort to dispel such misconceptions and likewise to address the needs of different population sub-groups.  相似文献
