Although transactional sex has been linked to undesirable sexual health outcomes, there is a lack of clarity as to the meaning
of the practice, which appears to extend beyond behaviors related to women’s economic circumstances. This article explored
the perspectives of parents and unmarried young people on motivations for, and beliefs about, transactional sex in rural Tanzania
using an ethnographic research design. Data collection involved 17 focus groups and 46 in-depth interviews with young people
aged 14–24 years and parents/caregivers. Transactional sex was widely accepted by both parents and young people. Male parents
equated sexual exchange to buying meat from a butcher and interpreted women’s demand for exchange before sex with personal
power. Young men referred to transactional sex as the easiest way to get a woman to satisfy their sexual desires while also
proving their masculinity. Young women perceived themselves as lucky to be created women as they could exploit their sexuality
for pleasure and material gain. They felt men were stupid for paying for “goods” (vagina) they could not take away. Mothers
were in agreement with their daughters. Although young women saw exploitation of the female body in positive terms, they were
also aware of the health risks but ascribed these to bad luck. Interventions aimed at tackling transactional sex in the interests
of women’s empowerment and as a strategy for HIV prevention need to understand the cultural beliefs associated with the practice
that may make it thrive despite the known risks. 相似文献

In this qualitative study we aimed to describe how older women in a crowded urban community perceive the food insecurity experience and deal with it. In-depth interviews were conducted among 30 Thai older women. Results revealed that older women perceived their food insecurity experience as a negative effect of the current economic downturn globally. They felt that they were confronting a crisis. Problems they dealt with included six issues. The women employed management strategies around food, health, money, and family. Our results suggest a need for welfare reform that facilitates management strategies aimed to meet food security. 相似文献

This community-based, qualitative study conducted in rural Kisesa District, Tanzania, explores perceptions and experiences of barriers to accessing the national antiretroviral programme among self-identified HIV-positive persons. Part of wider operations research around local introduction of HIV therapy, the study involved consultation with villagers and documented early referrals' progress through clinical evaluation and, if eligible, further training and drug procurement. Data collection consisted of 16 participatory group discussions with community members and 18 in-depth interviews with treatment-seekers. Although participants welcomed antiretroviral therapy, they feared that transportation and supplementary food costs, the referral hospital's reputation for being unfriendly and confusing, and difficulties in sustaining long-term treatment would limit accessibility. Fear of stigma framed all concerns, posing challenges for contacting referrals who did not want their status disclosed or expressed reluctance to identify a "treatment buddy" as required by the programme. To mitigate logistical barriers, transportation costs were paid and hospital visits facilitated. Participants reported satisfaction with eligibility testing, finding the process easier than anticipated. Most were willing to join a support group and some changed attitudes toward disclosure. However, both experienced and anticipated discrimination continue to hinder widespread antiretroviral therapy (ART) uptake. While simple measures to reduce perceived barriers improved initial access to treatment and helped overcome anxiety among early referrals, pervasive stigma remains the most formidable barrier. Encouraging successful referrals to share their positive experiences and contribute to nascent community mobililzation could start to address this seemingly intractable problem. 相似文献

The authors used a one-group pre-test-post-test design to examine the feasibility and acceptability of an osteoporosis prevention program and the effects of the program on knowledge, health beliefs, self-efficacy; and osteoporosis preventive behaviors in older adults. Participants included 48 older adults who attended a health center in Thailand. Results revealed that the program was feasible and acceptable. A significant improvement in osteoporosis knowledge, health beliefs, self-efficacy, and osteoporosis preventive behaviors occurred. Findings suggest that the program helps older adults incorporate new knowledge and skills into their daily lives and helps them maintain bone health. 相似文献

BACKGROUND: Antenatal clinic (ANC) surveillance is the primary source of HIV prevalence estimates in low-resource settings. In younger women, prevalence approximates incidence. Sexual behavior monitoring to explain HIV distribution and trends is seldom attempted in ANC surveys. We explore the use of marital history in ANC surveillance as a proxy for sexual behavior. METHODS: Five ANC clinics in a rural African district participated in surveillance from 1999 to 2004. Unlinked anonymous HIV testing and marital history interviews (including age at first sex and socioeconomic variables) were conducted. Data on women aged <25 years were analyzed. RESULTS: Inferred sexual exposure before marriage and after first marriage increased the adjusted odds of infection with HIV by more than 0.1 for each year of exposure. Increasing years within a first marriage did not increase HIV risk. After adjusting for age, women in more recent birth cohorts were less likely to be infected. CONCLUSIONS: Marital status is useful behavioral information and can be collected in ANC surveys. Exposure in an ongoing first marriage did not increase the odds of infection with HIV in this age group. HIV prevalence decreased over time in young women. ANC surveillance programs should develop proxy sexual behavior questions, particularly in younger women. 相似文献

To study the association of the consumption of alcohol and other psychoactive drugs with sexual risk behaviour for HIV infection, data from a representative sample of the Spanish population aged 18-39 years were analysed. A national household survey was carried out in 1996 using a combination of face-to-face interviews and self-administered questionnaires. The survey included 5253 subjects aged 18-39 years who provided information on alcohol and drug consumption, number of sexual partners and condom use with the steady partner and with casual partners in the 12 months before the survey. Of those surveyed, 27.4% had been drunk at least once and 20.5% had consumed drugs. Both behaviours were associated with male sex, younger age, higher educational level, being single and having had more than one sexual partner. In the logistic regression analysis adjusting for the sociodemographic variables, the greater frequency of drunkenness and cannabis use were associated with having more than one sexual partner. Regular condom use was significantly less frequent among cocaine users and more frequent among opiate users, but was not associated with the use of other drugs. Sexual risk behaviour (i.e. more than one partner and failure to use a condom regularly) was more frequent among persons who had been drunk or used cannabis or cocaine. Excessive consumption of alcohol, and cannabis and cocaine use are independently associated with sexual behaviour involving greater risk of HIV infection or transmission. 相似文献

OBJECTIVE: Bioactive food ingredients influence energy balance by exerting weak thermogenic effects. We studied whether the thermogenic effect of a combination of capsaicin, green tea extract (catechins and caffeine), tyrosine, and calcium was maintained after 7-day treatment and whether local effects in the gastric mucosa were involved in the efficacy. DESIGN: The present study was designed as a 3-way crossover, randomised, placebo-controlled, double-blinded intervention.SETTING: Department of Human Nutrition, RVAU, Denmark. SUBJECTS: A total of 19 overweight to obese men (BMI: 28.0+/-2.7 kg/m2) were recruited by advertising locally. INTERVENTION: The subjects took the supplements for a period of 7 days. The supplements were administrated as a simple supplement with the bioactive ingredients, a similar enterocoated version, or placebo. In all, 24-h energy expenditure (EE), substrate oxidations, spontaneous physical activity (SPA), and heart rate were measured in respiration chambers on the seventh day of each test period.Results:After adjustment for changes in body weight and SPA, 24-h EE was increased by 160 kJ/day (95% CI: 15-305) by the simple preparation as compared to placebo, whereas the enterocoated preparation had no such effect (53 kJ/day, -92 to 198); simple vs enterocoated versions (P=0.09). The simple preparation produced a deficit in 24-h energy balance of 193 kJ/day (49-338, P=0.03). Fat and carbohydrate oxidation were equally increased by the supplements.CONCLUSION: A supplement containing bioactive food ingredients increased daily EE by approximately 200 kJ or 2%, without raising the heart rate or any observed adverse effects. The lack of effect of the enterocoated preparation suggests that a local action of capsaicin in the gastric mucosa is a prerequisite for exerting the thermogenic effect. 相似文献

In intervention and observational studies, it is necessary to determine the number of blood samples required to estimate the true value of Fe-status measures. The aim of the present study was to determine the number of days for blood sampling required in order to measure the 'true value' of five Fe-status parameters in young Fe-depleted women and to investigate the effect of menstrual cycle on these measures. Twelve women (aged 23-30 years), non-anaemic but with low Fe stores, participated in the study. Venous blood samples were collected under standardised conditions on fifteen non-consecutive days during a 5-week period. All blood samples were analysed for Hb, serum ferritin (SF), serum transferrin receptors (sTfR), red blood cell volume distribution width (RDW) and reticulocytes (RET), and body Fe stores were calculated as the ratio between sTfR and SF. No systematic changes were found in the investigated parameters during the study. When analytical variations were accounted for, the day-to-day variations (CV%) were as follows: Hb 2.9 %, SF 8.2 %, RET 26.0 %, RDW 2.4 % and sTfR 8.1 %. Calculating the 'true value' with a 5 % significance level and 80 % power showed that one blood sample was sufficient for Hb, SF, sTfR and RDW, whereas seven blood-sampling days were needed for RET. In this study, no significant differences in Fe status were found across the menstrual cycle. The conclusions from this study are valid for studies conducted under similar strict conditions. 相似文献
