Research has shown that increasing numbers of teenagers are going online to find health information, but it is unclear whether there are disparities in the prevalence of online health seeking among young Internet users associated with social and economic conditions. Existing literature on Internet uses by adults indicates that low income, less educated, and minority individuals are less likely to be online health seekers. Based on the analysis of data from the Pew Internet and American Life Project for the US, this study finds that teens of low education parents are either as likely as or even more likely than teens of high education parents to seek online health information. Multiple regression analysis shows that the higher engagement in health seeking by teens of low education parents is related to a lower prevalence of parental Internet use, suggesting that some of these teens may be seeking online health information on behalf of their low education parents. Implications of these findings are discussed in relation to the issues of the digital divide and digital empowerment.  相似文献

Recent New Labour policy for the ‘modernisation’ of Government places a good deal of emphasis on decentralisation. This emphasis is particularly marked in relation to the organisation of primary care. However, like hospitals and other National Health Service institutions, primary care trusts (PCTs) are subject to a substantial raft of centrally established performance targets and indicators, including those which contribute to the public award of between zero and three performance ‘stars’. This raises questions about the extent to which employees can exercise autonomy in the context of rigid top‐down directives. This paper presents findings from a study using participant observation and interviews to examine the impact of a training course aimed ostensibly at increasing employee autonomy in an English PCT. The suggestion is that attempts to make employees more autonomous can be seen as a strategy for increasing central control based upon the internalisation by the employees of centrally promulgated values. The attraction of such strategies is that they may be potentially more effective and less costly than alternative strategies of direct control. However, the study suggests that the outcome of attempts by such methods as programmes to increase employee autonomy may be very different from those intended.  相似文献

PurposeWe developed and validated a measure that assesses the latent construct of sexual and reproductive empowerment among adolescents and young adults. A specific measure for this group is critical because of their unique life stage and circumstances, which often includes frequent changes in sexual partners and involvement from parents in decision-making.MethodsAfter formative qualitative research, a review of the literature, and cognitive interviews, we developed 95 items representing nine dimensions of sexual and reproductive empowerment. Items were then fielded among a national sample of young people aged 15–24 years, and those who identified as sexually active completed a 3-month follow-up survey. We conducted psychometric analysis and scale validation.ResultsExploratory factor analysis on responses from 1,117 participants resulted in the Sexual and Reproductive Empowerment Scale for Adolescents and Young Adults, containing 23 items captured by seven subscales: comfort talking with partner; choice of partners, marriage, and children; parental support; sexual safety; self-love; sense of future; and sexual pleasure. Validation using logistic regression demonstrated that the subscales were consistently associated with sexual and reproductive health information and access to sexual and reproductive health services measured at baseline and moderately associated with the use of desired contraceptive methods at 3-month follow-up.ConclusionsThe Sexual and Reproductive Empowerment Scale for Adolescents and Young Adults is a new measure that assesses young people’s empowerment regarding sexual and reproductive health. It can be used by researchers, public health practitioners, and clinicians to measure sexual and reproductive empowerment among young people.  相似文献

This paper presents a typology and transactional model of how close relatives cope with excessive drinking, drug-taking or gambling in the family. These are illustrated with four examples taken from a series of research projects in which relatives have been interviewed to understand better how they react and respond. Such information is the groundwork for a World Health Organization initiative to help primary health care workers respond to the needs of relatives. The philosophy behind this initiative, and the steps that primary health care workers might take, are outlined. It is proposed that such workers can help close relatives to find the best coping methods in their circumstances, and that this approach might constitute an important, and hitherto neglected, form of secondary prevention.  相似文献

The authors developed a union sponsored 2-day human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) "train the trainer" program for healthcare workers in the San Francisco Bay Area. The program incorporated the "education for action" approach in an effort to respond to the inadequacies in many traditional, institutional trainings. Service Employees International Union (SEIU) and Labor Occupational Health Program (LOHP) conducted the HIV/AIDS "train the trainer" program for approximately 100 healthcare workers in county public hospitals and community health clinics. After completing the program, these workers went back to their healthcare facilities, or community organizations, and led additional classes on HIV/AIDS transmission and prevention for approximately 600 more people. The goal of the program was to empower healthcare workers to: 1) identify the occupational risks associated with exposure to blood and potentially infectious body fluids at the workplace; 2) develop strategies to reduce those risks; 3) discuss their feelings about caring for an HIV/AIDS patient; and, 4) conduct HIV/AIDS workshops at the workplace.  相似文献

A recently independent state, Timor-Leste, is progressing towards socioeconomic development, prioritizing women empowerment while its increased fertility rate (4.1) could hinder the growth due to an uncontrolled population. Currently, limited evidence shows that indicators of women''s empowerment are associated with fertility preferences and rates. The objective of this study was to assess the association between women empowerment and fertility preferences of married women aged 15 to 49 years in Timor-Leste using nationally representative survey data. The study was conducted using the data of the latest Timor-Leste Demographic and Health Survey 2016. The study included 4040 rural residents and 1810 urban residents of Timor-Leste. Multinomial logistic regression has been performed to assess the strength of association between the exposures indicating women''s empowerment and outcome (fertility preference). After adjusting the selected covariates, the findings showed that exposures that indicate women empowerment in DHS, namely, the employment status of women, house and land ownership, ownership of the mobile phone, and independent bank account status, contraceptive use, and the attitude of women towards negotiating sexual relations are significantly associated with fertility preferences. The study shows higher the level of education, the less likely were the women to want more children, and unemployed women were with a higher number of children. Our study also found that the attitude of violence of spouses significantly influenced women''s reproductive choice. However, employment had no significant correlation with decision-making opportunities and contraceptive selection due to a lack of substantial data. Also, no meaningful data was available regarding decision-making and fertility preferences. Our findings suggest that women''s empowerment governs decision-making in fertility preferences, causing a decline in the fertility rate.  相似文献

The birth of a sick newborn provides great stress for the family. During the illness, the family must face charged issues, including the loss of the perfect child they had anticipated and a fear that their baby may die. Issues related to helping these vulnerable families are examined, including response to the birth of a sick baby, communication with the family, preparation for discharge and long term hospitalization, as well as issues pertaining to the staff of the neonatal intensive care unit.  相似文献

The Alzheimer's Respite Care Program is an innovative project designed to serve caregivers of Alzheimer's clients. This unique model offers both in-home and instilutionally based respite care. Two community organizations which offer Adult Day Care respite forged a partnership to coordinate and expand their continuum of care, bringing many of the benefits of a day care setting into the home. This paper compares the original project conceptualization with its current design today. Factors affecting this evolution are explored together with program modifications incorporated to more appropriately respond to local needs. Key marketing strategies are discussed coupled with a presentation of program successes and recommendations for the future.  相似文献

This article explores the contribution of self‐help/mutual aid groups to mental well‐being. Self‐help/mutual aid groups are self‐organising groups where people come together to address a shared a health or social issue through mutual support. They are associated with a range of health and social benefits, but remain poorly understood. This article draws on data from stage one of ESTEEM, a project which runs from 2010 to 2013. Stage one ran from 2010 to 2011 and involved participatory, qualitative research carried out in two UK sites. Twenty‐one groups were purposively selected to include a range of focal issues, longevity, structures and ethnic backgrounds. Researchers carried out 21 interviews with group coordinators and twenty group discussions with members to explore the groups' purpose, nature and development. Preliminary analysis of the data suggested that mental well‐being was a common theme across the groups. Subsequently the data were re‐analysed to explore the groups' contribution to mental well‐being using a checklist of protective factors for mental well‐being as a coding framework. The findings showed that groups made a strong contribution to members' mental well‐being by enhancing a sense of control, increasing resilience and facilitating participation. Group members were uplifted by exchanging emotional and practical support; they gained self‐esteem, knowledge and confidence, thereby increasing their control over their situation. For some groups, socio‐economic factors limited their scope and threatened their future. The article provides an evidence‐base which illustrates how self‐help/mutual aid groups can enhance mental well‐being. If supported within a strategy for social justice, these groups enable people with varied concerns to develop a tailored response to their specific needs. The authors suggest that policy‐makers engage with local people, investing in support proportionate to the needs of different populations, enabling them to develop their own self‐help/mutual aid groups to enhance their sense of mental well‐being.  相似文献
