Background

Use of the Internet for finding sexual partners is increasing, particularly among men who have sex with men (MSM). In particular, MSM who seek sex online are an important group to target for human immunodeficiency virus (HIV)/sexually transmitted infection (STI) interventions because they tend to have elevated levels of sexual risk behavior and because the Internet itself may serve as a promising intervention delivery mechanism. However, few studies have examined the correlates of online sexual partner seeking among MSM in sub-Saharan Africa.

Objective

These analyses aim to describe the prevalence of using the Internet to find new male sexual partners among MSM in two southern African countries. In addition, these analyses examine the sociodemographic characteristics, experiences of discrimination and stigma, mental health and substance use characteristics, and HIV-related knowledge, attitudes, and behaviors among MSM associated with meeting sex partners online.

Methods

MSM were enrolled into a cross-sectional study across two sites in Lesotho (N=530), and one in Swaziland (N=322) using respondent-driven sampling. Participants completed a survey and HIV testing. Data were analyzed using bivariate and multivariable logistic regression models to determine which factors were associated with using the Internet to meet sex partners among MSM.

Results

The prevalence of online sex-seeking was high, with 39.4% (209/530) of MSM in Lesotho and 43.8% (141/322) of MSM in Swaziland reporting meeting a new male sexual partner online. In the multivariable analysis, younger age (adjusted odds ratio [aOR] 0.37, 95% confidence interval [CI] 0.27-0.50 per 5 years in Lesotho; aOR 0.68, 95% CI 0.49-0.93 in Swaziland), having more than a high school education (aOR 18.2, 95% CI 7.09-46.62 in Lesotho; aOR 4.23, 95% CI 2.07-8.63 in Swaziland), feeling scared to walk around in public places (aOR 1.89, 95% CI 1.00-3.56 in Lesotho; aOR 2.06, 95% CI 1.23-3.46 in Swaziland), and higher numbers of male anal sex partners within the past 12 months (aOR 1.27, 95% CI 1.01-1.59 per 5 partners in Lesotho; aOR 2.98, 95% CI 1.51-5.89 in Swaziland) were significantly associated with meeting sex partners online in both countries. Additional country-specific associations included increasing knowledge about HIV transmission, feeling afraid to seek health care services, thinking that family members gossiped, and having a prevalent HIV infection among MSM in Lesotho.

Conclusions

Overall, a high proportion of MSM in Lesotho and Swaziland reported meeting male sex partners online, as in other parts of the world. The information in this study can be used to tailor interventions or to suggest modes of delivery of HIV prevention messaging to these MSM, who represent a young and highly stigmatized group. These data suggest that further research assessing the feasibility and acceptability of online interventions will be increasingly critical to addressing the HIV epidemic among MSM across sub-Saharan Africa.  相似文献

OBJECTIVE: To assess whether sexually transmitted infections (STIs) and sexual behavior are independently associated with HIV-1 among adult women, men, and teenagers in rural Uganda. DESIGN: Cross-sectional survey. METHODS: All adults (13 years and older) residing in 18 communities were invited to participate. HIV status was determined from serum samples and data collected during confidential interview. Independent effects of risk factors for HIV were estimated using adjusted odds ratios (ORs) with 95% confidence intervals (CIs) from logistic regression. RESULTS: Women reporting genital ulcers in the last 12 months were over twice as likely to be HIV positive after adjustment for sociodemographic factors and number of lifetime sexual partners (OR, 2.5; 95% CI, 1.9-3.4). Equivalent associations were stronger for men (OR, 3.2; 95% CI, 2.2-4.7) but weaker for teenagers (OR, 2.0, 95% CI, 0.5-8.7). Number of lifetime sexual partners was associated ( p <.05) with HIV status for women, men, and teenagers independently of reported genital ulcers. Teenagers reporting casual partners were over four times ( p <.001), and men reporting condom use almost twice ( p <.001), as likely to be HIV positive. Neither history of genital discharge nor other measures of sexual behavior were independently related to HIV status. CONCLUSION: Reported STIs and sexual behavior are independently associated with HIV in rural Uganda. Community-based interventions to reduce HIV should target both and should include teenagers.  相似文献

Background

HIV spread continues at high rates from infected persons to their sexual partners. In 2009, an estimated 2.6 million new infections occurred globally. People living with HIV (PLHIV) receiving treatment are in contact with health workers and therefore exposed to prevention messages. By contrast, PLHIV not receiving ART often fall outside the ambit of prevention programs. There is little information on their sexual risk behaviors. This study in Mombasa Kenya therefore explored sexual behaviors of PLHIV not receiving any HIV treatment.

Results

Using modified targeted snowball sampling, 698 PLHIV were recruited through community health workers and HIV-positive peer counsellors. Of the 59.2% sexually-active PLHIV, 24.5% reported multiple sexual partners. Of all sexual partners, 10.2% were HIV negative, while 74.5% were of unknown HIV status. Overall, unprotected sex occurred in 52% of sexual partnerships; notably with 32% of HIV-negative partners and 54% of partners of unknown HIV status in the last 6 months. Multivariate analysis, controlling for intra-client clustering, showed non-disclosure of HIV status (AOR: 2.38, 95%CI: 1.47-3.84, p < 0.001); experiencing moderate levels of perceived stigma (AOR: 2.94, 95%CI: 1.50-5.75, p = 0.002); and believing condoms reduce sexual pleasure (AOR: 2.81, 95%CI: 1.60-4.91, p < 0.001) were independently associated with unsafe sex. Unsafe sex was also higher in those using contraceptive methods other than condoms (AOR: 5.47, 95%CI: 2.57-11.65, p < 0.001); or no method (AOR: 3.99, 95%CI: 2.06-7.75, p < 0.001), compared to condom users.

Conclusions

High-risk sexual behaviors are common among PLHIV not accessing treatment services, raising the risk of HIV transmission to discordant partners. This population can be identified and reached in the community. Prevention programs need to urgently bring this population into the ambit of prevention and care services. Moreover, beginning HIV treatment earlier might assist in bringing this group into contact with providers and HIV prevention services, and in reducing risk behaviors.  相似文献

Background

The aim of this study was to describe the extent of the HIV epidemic among women in the Republic of Georgia and to identify factors associated with HCV co-infection in this population.

Findings

All women aged ≥18 years who were diagnosed with HIV between 1989 and 2006 were identified through the National HIV/AIDS surveillance database. Medical records were reviewed for demographic characteristics, risk factors and HCV serostatus. A total of 249 women were identified. Only 4% declared injection drug use (IDU); sex work was reported by 9%. Substantial risk factors were identified among the women's sexual partners, nearly 69% of whom were IDUs, 84% were HIV positive and 66% HCV positive. Seventeen percent of women were seropositive for HCV. Factors significantly associated with HCV seropositivity in bivariate analyses among non-IDU women were partner IDU+ [Prevalence ratio (PR): 4.5 (95% CI: 1.4, 14.2)], and partner HCV+ [PR: 7.2 (95% CI: 1.8, 29.5)].

Conclusions

The HIV epidemic in the Republic of Georgia is closely tied to the IDU community. Evidence-based interventions targeting IDU and partners of IDU are urgently required to halt the spread of the HIV epidemic in the country.  相似文献

Background

Prevalence of herpes simplex type 2 virus (HSV-2) is high worldwide. Previous studies in Uganda were rural or in women. We estimated age and sex-specific sero-prevalence of HSV-2 in Kampala, Uganda.

Methods

Using two-stage random sampling stratified on population density, a survey of persons 15–65 years was conducted. Type-specific serological tests for HSV-2, HSV-1(HerpeSelect2 and 1 ELISA), HIV (Rapid tests and ELISA), syphilis (RPR and TPHA) were done. Additional prevalence analysis included post-stratification weighting on the Uganda 2002 Census gender distribution.

Results

Among 1124 persons, HSV-2 prevalence was 58% (95% CI: 55, 60), HSV-1; 98% (95% CI: 97.6, 99.1), HIV; 17.7% (95% CI: 14.8, 19.2) and syphilis; 1.7% (95% CI: 1.4, 1.9). Weighted HSV-2 prevalence was 53.8% (Women; 63.8%, men; 43.2%), similar to unweighted data. Weighted HIV prevalence was 20.7% in women, 8.6% in men. Of 165 HIV infected persons, 85.4% had HSV-2. Risk factors for HSV-2 were being a woman (OR 2.0; 95% CI: 1.42, 2.78), age (OR 3.3; 95% CI: 2.43, 4.53), education (OR 1.70; 95% CI: 1.34, 2.34) and HIV (OR 4.5; 95% CI: 2.70, 7.50).

Conclusion

Prevalence of HSV-2 and HIV was high especially in women. Syphilis was rare. Awareness of herpes was low. Interventions in young people are needed.  相似文献

Background

An inverse association between socioeconomic status (SES) and mental health has been previously well reported, but the evidence is limited in Asian populations.

Purpose

We therefore investigated the association of SES and subjective mental health and prevalence of any mental disorders in the general population of Japan.

Method

We used data from the World Mental Health Japan Survey of 1,496 randomly selected people aged 20 years and older in Japan. Information on education level and household income were used as objective SES indicators, and subjective social status (SSS) was measured by responses to a question regarding social position. We calculated odds ratios of SES indicators for poor subjective mental health and 12-month prevalence of any mental disorders.

Results

The adjusted odds ratio (OR) (95 % confidence interval (CI)) of respondents who rated themselves as lower than middle status in the country (low SSS group) for poor subjective mental health was 2.24 (95 % CI: 1.41, 3.57) with reference to those who rated themselves as higher than middle status (high SSS group). Similarly, inverse associations of education level and household income with poor subjective mental health were identified. A J-shaped association was confirmed between SSS and 12-month prevalence of any mental disorders. The adjusted OR (95 % CI) of SSS for any mental diseases was 0.53 (95 % CI: 0.32, 0.86) for the middle SSS group and 1.61 (95 % CI: 0.96, 2.72) for the low SSS group, compared with the high SSS group. Those associations were not attenuated when objective SES indicators were adjusted.

Conclusion

We found inversely linear associations between subjective and objective SES and poor subjective mental health among Japanese men and women. SSS was not significantly associated with 12-month prevalence of any mental disorders. Substantial social inequalities in mental health were identified in Japan, which has been considered an egalitarian society with relatively few inequalities in health.  相似文献

Background

Protecting the health of the work force has become an important issue in public health research.

Purpose

This study aims to explore potential associations between supportive leadership style (SLS), an aspect of leadership behavior, and self-rated health (SRH) among employees.

Method

We drew on cross-sectional data from a cohort of industrial workers (n?=?3,331), collected in 2009. We assessed employees' ratings of supportive, employee-oriented leadership behavior at their job, their SRH, and work stress as measured by the effort–reward model and scales measuring demands, control, and social support. Logistic regression estimated odds ratios (ORs) and corresponding 95 % confidence intervals (CIs) for the association between the perception of poor SLS and poor SRH controlling for work-related stress and other confounders. Sensitivity analyses stratified models by sex, age, and managerial position to test the robustness of associations.

Results

Perception of poor SLS was associated with poor SRH [OR 2.39 (95 % CI 1.95–2.92)]. Although attenuated following adjustment for measures of work-related stress and other confounders [OR 1.60 (95 % CI 1.26–2.04)], the magnitude, direction, and significance of this association remained robust in stratified models in most subgroups.

Conclusion

SLS appears to be relevant to health in the workplace. Leadership behavior may represent a promising area for future research with potential for promoting better health in a large segment of the adult population.  相似文献

Background

Disclosure of HIV positive sero-status to sexual partners, friends or relatives is useful for prevention and care. Identifying factors associated with disclosure is a research priority as a high proportion of persons living with HIV/AIDS (PHA) never disclose.

Objective

To identify factors associated with disclosure among PHAs in Mityana district of Uganda.

Methods

Using a case control design, we compared 139 PHAs who had disclosed to 139 PHA who had not disclosed regarding socio demographic characteristics, sexual behaviour, individual experiences and perceptions about disclosure, as well as on health facility/community correlates of disclosure.

Results

The independent factors that favour disclosure are not fearing negative outcomes of disclosure adjusted odds ratio (AOR) 7.00, 95 % confidence interval (95% CI) 3.03–16.95, having communication skills to disclose (AOR 12.08, 95% CI 4.94–29.51), having initiated anti-retroviral therapy (AOR 7.51, 95% CI 3.42–16.49), not having tested for HIV during ante-natal clinic (AOR 5.07, 95% CI 1.95–13.10), receiving ongoing counselling (AOR 4.33, 95% CI 1.50–12.51) and having ever seen a PHA publicly disclose his/her HIV status AOR 2.73, 95% CI 1.24–6.02).

Conclusions

PHAs that have not initiated anti-retroviral therapy (ART), test for HIV in ante-natal clinic and fear negative outcomes need more help in disclosure. Measures that empower PHA to disclose such as those that lead to improved communication skills should be reinforced during ongoing counselling.  相似文献

Background

Reproductive health and sexually transmitted diseases (STD) account for a high proportion of health problems in the rural-to-urban young female migrant workers in China. Improving these conditions remains highly challenging.

Purpose

To developed an educational programme to advance the reproductive health of the female workers.

Method

An intervention study was conducted between July 2010 and April 2011 in Shenzhen. Two commune factories were selected to participate and provided a control cluster receiving routine local government health services and a second cluster receiving an educational intervention in addition to the routine services. The intervention included distribution and free access to educational study materials. The factory workers’ knowledge, attitudes and behaviour in the area of reproductive health and STD were the main study outcomes.

Results

Compared with the control cluster, at the 6-month follow-up assessment, the intervention cluster had a significantly higher proportion of correct answers to queries about human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) (standardised coefficients of multiple linear regression (B) 0.047; P?=?0.020) and awareness of places providing free contraceptives (odds ratio [OR] 2.011, 95 % confidence interval [CI] 1.635–2.472; P?<?0.001), and a significantly lower proportion accepting premarital sex (OR 0.492, 95 % CI 0.416–0.582; P?<?0.001), practising premarital sex (OR 0.539, 95 % CI 0.478–0.608; P?<?0.001) or suffering from gynaecological disorders (OR 0.801, 95 % CI 0.697–0.921; P?=?0.002).

Conclusion

A community-based educational intervention targeting unmarried female migrant workers appears to be effective in substantially improving their knowledge of reproductive health and their attitudes and behaviour towards health, and in reducing prevalence of STD.  相似文献

Background

Late diagnosis and presentation to human immune deficiency virus (HIV)/acquired immune deficiency syndrome care reduce the benefits of antiretroviral therapy and increase the risk of HIV transmission.

Objectives

This study was conducted to identify determinants of late presentation to HIV care among people living with HIV in Southern Tigray, Northern Ethiopia.

Methods

An institution based un-matched case–control (1:2 ratios) supported with qualitative data was conducted in Southern Tigray Zone from March 1 to April 30, 2014. Individuals with HIV enrolled from six randomly selected health facilities were included in the study. Cases were people living with HIV who had cluster of differentiation four count <350 cells/μl or World Health Organization stages 3 or 4. A total of 442 study participants were included by systematic sampling techniques. Bivariable and multivariable binary logistic regression model was used to identify associated factors. Odds ratio with 95 % CI was computed to assess the strength of the associations.

Result

Age categories, 25–29 years [AOR 3, 95 % CI (1.2–8.1)] and 35–39 years [AOR 4.1, 95 % CI (1.4–12.5)], having two [AOR 6, 95 % CI (1.3–28)] and more [AOR 5.2, 95 % CI (1.1–24.8)] lifetime sexual partners, poor social support [AOR 2.3, 95 % CI (1.26–4.30)], second (next to lowest) wealth quintile [AOR 3.3, 95 % CI 91.3–8.5)], fear of stigma [AOR 4.4, 95 % CI (2.2–8.3)], fear of losing job [AOR 6.8, 95 % CI (1.8–24.5)], and reported severe illness [AOR 4.3, 95 % CI (2.26–8)] were identified to be the risk factors for late presentation.

Conclusion

Low socio-economic status and social support, fear of stigma were potential risk factors for late presentation. Efforts towards promoting early care seeking should target on these factors in the study area and other similar settings.

Background

While the effects of initiation of antiretroviral treatment (ART) on risky sexual behavior have been extensively studied, less is known about the long-term changes in risky sexual behavior over time in resource-poor settings.

Methods

We conducted a secondary longitudinal analysis of one rural and one urban cohort of patients who initiated ART in Uganda between April 2004 and July 2007 followed up-to 2016. Data on sexual behavior were collected every 6 months for 3.5 years in individuals on ART?≥?4 years (baseline) when a behavioral questionnaire was introduced. Risky sexual behavior was defined as sexual intercourse with?≥?2 partners or inconsistent or no condom use in previous 6 months. We report characteristics overall, and by cohort. We used multivariable generalized estimating equations logistic regression to assess the effects of time on ART on risky sexual behavior.

Results

Of 1012 participants, 402 (39.8%) were urban and 610 (60.2%) were rural residents. Mean age was 42.8 years (SD 8.5). Mean duration of follow-up was 51.3 months (SD 15.3), but longer for urban than rural participants (64.5 vs 36.4 months). Risky sexual behavior declined from 33.1% at baseline to 9.6% after 3.5 years of follow-up in the rural cohort (p?≤?0.01 for the test of trend) and was unchanged from 9.7% at baseline to 9.9% after 3.5 years in the urban cohort (p?=?0.51). Receiving care at a rural clinic (aOR 4.99, 95% CI 3.64–6.84); male gender (aOR 1.66, 95% CI 1.26–2.19) and being younger (aOR 5.60, 95% CI 3.80–8.25 for 18–34 years and aOR 2.34, 95% CI 1.74–3.14 for 35–44 years) were associated with increased odds of risky sexual behavior. Not being married (aOR 0.25; 95% CI 0.19–0.34), and longer time on ART (aOR 0.71 95% CI 0.67–0.76) were associated with reduced odds of risky sex.

Conclusions

We observed a decline in risky sexual behavior in rural people on long-term (≥?4 years) ART. Rural, male and young individuals had higher odds of self-reported risky sexual behavior. ART programs should continue to emphasize risk reduction practices, especially among people receiving care in rural health facilities, males, younger individuals and those who are married.

Background

Sixty percent of new HIV infections in Uganda occur in stable relationships between HIV discordant couples. Given the importance of fertility in Uganda, we hypothesized that unsafe sexual practices may be used to found a family/replace a dead child. Thus, we explored sexual practices to understand to what extent these are influenced by the desire to have children and the implications for HIV transmission among discordant couples.

Methods

A cross-sectional survey of 114 HIV discordant couples in Kampala, and in-depth interviews with 15 purposively selected couples. Quantitative data were analysed using STATA. Multivariate logistic regression analysis done to identify factors associated with consistent condom use. Thematic content analysis of qualitative data was done using NVIVO 2.

Results

Participants wanting children and those with multiple sexual partners were less likely to use condoms (Adj OR 0.51, and 0.36 respectively). Three of the five types of sexual practices used by couples do not allow pregnancy to occur. Main reasons for wanting a child included: ensuring lineage continuity and posterity, securing relationships and pressure from relatives to reproduce. Challenges included: risk of HIV transmission to partner and child, lack of negotiating power for safer sex, failure of health systems to offer safe methods of reproduction

Conclusions

HIV sero-discordant couples with strong desire for childbearing have a dilemma of risking HIV infection or infecting their spouse. Some risk transmission of HIV infection to reproduce. We need to address gender issues, risky behaviour and reproductive health services for HIV sero-discordant couples.  相似文献

Background

The association of variants in the IL23R gene with psoriasis and psoriatic arthritis (PsA) is a robust genetic finding

Objectives

To assess whether combined evidence shows the association between IL23R polymorphisms and susceptibility to psoriasis/PsA.

Methods

We conducted a meta-analysis to examine the association between the IL23R rs11209026 (Q381R), rs7530511 (L310P), and rs2201841 polymorphisms and psoriasis/PsA.

Results

Thirteen articles met the inclusion criteria and contributed data to the meta-analysis. For rs11209026, the odds ratios (ORs) of minor alleles for psoriasis and PsA were 0.616 [95?% confidence interval (CI) 0.563–0.674] and 0.630 (95?% CI 0.524–0.757), respectively. For rs7530511, the pooled ORs were 0.820 (95?% CI 0.764–0.879) for psoriasis and 0.875 (95?% CI 0.766–1.000) for PsA; for rs2201841 the OR was 1.121 (95?% CI 1.031–1.219) for psoriasis. In genotypic analysis, the association of rs11209026 (A) and rs7530511 (T) were compatible with the dominant model (P?P?=?0.001 respectively). The overall ORs for GG vs. AA (OR 1.339; 95?% CI 1.151–1.558), GG vs. GA (OR 1.143; 95?% CI 1.004–1.300), dominant (OR 1.226; 95?% CI 1.143–1.316), and recessive (OR 1.254; 95?% CI 1.115–1.411) models of rs2201841 were all significantly increased in psoriasis. No publication bias was present.

Conclusions

Our results demonstrate a significant association between IL23R gene polymorphisms and psoriasis/PsA.  相似文献

Background

Intimate partner violence (IPV) is recognized all over the world for its association with mental health problems in women. In Pakistan, such violence occurs commonly, but detailed information on mental health effects is scarce. The purpose of this study is to focused on married couples in urban Karachi to investigate mental health effects associated with physical, sexual and psychological violence perpetrated by husbands towards wives. Disclosure rates and health care-seeking behaviour were also investigated.

Method

This cross-sectional study involved 759 women between the ages of 25 and 60 years, selected using a multi-stage random sampling technique. The women were interviewed by trained community midwives using a structured questionnaire.

Results

In the total population of women, mental symptoms were prevalent. Women subjected to any form of violence reported, however, considerably poorer mental health than unexposed women. A statistically significant difference for almost all of the studied health parameters persisted even after controlling for socio-demographic factors. The strongest associations were found for suicidal thoughts and physical violence (OR 4.41; 3.18–6.12), sexual abuse (OR 4.39; 3.17–6.07) and psychological abuse (OR 5.17; 3.28–8.15). The interviews revealed that only 27% of the women subjected to violence had disclosed this to anyone, in most cases to their parents.

Conclusion

The findings in this study highlight that the violence women have to face contributes to the development of multiple forms of psychological stress and serious mental health problems. Women’s restrictive life circumstances seriously hamper women’s empowerment. Reliable health surveillance system and health care services are needed to serve abused women. Policy initiatives focused on IPV and gender inequality in Pakistan should be initiated.  相似文献

Background

Whiplash injuries show a variable prognosis which is difficult to predict. Most individuals experiencing whiplash injuries rapidly recover but a significant proportion develop chronic symptoms and ongoing disability.

Purpose

By employing longitudinal data, we investigated how psychological and physical symptoms, self-rated health, use of health services and medications, health behavior and demographic factors predict recovery from whiplash.

Method

Data from two waves of a large, Norwegian, population-based study (The Nord-Trøndelag Health Study: HUNT2 and HUNT3) were used. Individuals reporting whiplash in HUNT2 (baseline) were identified in HUNT3 11 years later. The characteristics of individuals still suffering from whiplash in HUNT3 were compared with the characteristics of individuals who had recovered using Pearson’s chi-squared test, independent sample t-tests and logistic regression.

Results

At follow-up, 31.6 % of those reporting whiplash at baseline had not recovered. These individuals (n?=?199) reported worse health at baseline than recovered individuals (n?=?431); they reported poorer self-rated health (odds ratio [OR]?=?3.12; 95 % confidence interval [CI], 2.20–4.43), more symptoms of anxiety (OR?=?1.70; 95 % CI, 1.15–2.50), more diffuse somatic symptoms (OR?=?2.38; 95 % CI, 1.61–3.51) and more musculoskeletal symptoms (OR?=?1.21; 95 % CI, 1.13–1.29). Individuals still suffering from whiplash also visited more health practitioners at baseline (OR?=?1.18; 95 % CI, 1.06–1.32) and used more medications (OR?=?1.24; 95 % CI, 1.09–1.40).

Conclusion

Poor self-rated health seems to be a strong risk factor for whiplash injuries becoming chronic. Diffuse somatic symptoms, musculoskeletal symptoms and symptoms of anxiety at baseline are important prognostic risk factors. Knowledge of these maintaining risk factors enables identification of individuals at risk of non-recovery, facilitating adequate treatment for this vulnerable group.  相似文献

Background

Medical male circumcision (MMC) is now considered one of the best available evidence-based biomedical HIV prevention interventions. However, there is some concern about risks for behavioural disinhibition, or risk compensation, following MMC.

Purpose

The aim of this study was to test a brief one-session (180?min) group culturally tailored HIV risk reduction counselling intervention among men undergoing medical circumcision in South Africa in order to limit behavioural disinhibition.

Methods

A randomized controlled trial design was employed using a sample of 150 men, 75 in the experimental group and 75 in the control group. Comparisons between baseline and 3-month follow-up assessments on several key behavioural outcomes addressed by the intervention were done.

Results

Our study found that behavioural intentions and risk reduction skills significantly increased and sexual risk behaviour (reduction of the number of sexual partners and the number of unprotected vaginal sexual intercourse occasions) significantly decreased in the experimental compared to the control condition. However, male role norms did not change among the intervention conditions over time, while AIDS-related stigma beliefs significantly reduced in both conditions over time.

Conclusion

Study findings show that a relatively brief (one session) and focused HIV risk reduction counselling can have at least short-term effects on reducing sexual risk behaviours in populations at high risk for behavioural disinhibition following medical male circumcision.  相似文献

Background

Common single-nucleotide polymorphisms (SNPs) in microRNAs (miRNA) have been shown to be associated with susceptibility to several human diseases. We evaluated the associations of three SNPs (rs11614913, rs2910164, and rs3746444) in pre-miRNAs (miR-196a2, miR-146a, and miR-499) with the risk of ulcerative colitis (UC) in a Japanese population.

Methods

The rs11614913 (T?>?C), rs2910164 (C?>?G), and rs3746444 (A?>?G) SNPs were genotyped in 170 UC and 403 control subjects.

Results

The rs3746444 AG genotype was significantly higher among the UC group (odds ratio (OR)?=?1.51, 95% CI?=?1.03?C2.21, p?=?0.037). The rs3746444 AG genotype was associated with onset at an older age (OR?=?1.70, 95% CI?=?1.04?C2.78, p?=?0.035), left-sided colitis and pancolitis (left-sided colitis, OR?=?2.10, 95% CI?=?1.12?C3.94, p?=?0.024; pancolitis, OR?=?1.81, 95% CI?=?1.09?C3.01, p?=?0.028, left-sided colitis?+?pancolitis, OR?=?1.91, 95% CI?=?1.26?C2.92, p?=?0.003), higher number of times hospitalized (OR?=?2.63, 95% CI?=?1.22?C5.69, p?=?0.017), steroid dependence (OR?=?2.63, 95% CI?=?1.27?C5.44, p?=?0.014), and refractory phenotypes (OR?=?2.76, 95% CI?=?1.46?C5.21, p?=?0.002) while the rs3746444 AA genotype was inversely associated with the number of times hospitalized (2??, OR?=?0.36, 95% CI?=?0.17?C0.79, p?=?0.012), steroid dependence (OR?=?0.42, 95% CI?=?0.21?C0.88, p?=?0.021), and refractory phenotypes (OR?=?0.38, 95% CI?=?0.20?C0.72, p?=?0.003). The rs1161913 TT genotype also held a significantly higher risk of refractory phenotype (T/T vs. T/C?+?C/C, OR?=?2.21, 95% CI?=?1.17?C4.18, p?=?0.016).

Conclusions

Our results provided the first evidence that rs3746444 SNP may influence the susceptibility to UC, and both rs3746444 and rs11614913 SNPs may influence the pathophysiological features of UC.  相似文献

Background

HIV infection among children, particularly those under 24?months of age, is often rapidly progressive; as a result guidelines recommend earlier access to combination antiretroviral therapy (cART) for HIV infected children. Losses to follow-up (LTFU) and death in the interval between diagnosis and initiation of ART profoundly limit this strategy. This study explores correlates of LTFU and death prior to ART initiation among children.

Methods

The study is based on 337 HIV-infected children enrolled into care at an urban centre in The Gambia, including those alive and in care when antiretroviral therapy became available and those who enrolled later. Children were followed until they started ART, died, transferred to another facility, or were LTFU. Cox proportional hazards regression models were used to determine the hazard of death or LTFU according to the baseline characteristics of the children.

Results

Overall, 223 children were assessed as eligible for ART based on their clinical and/or immunological status among whom 73 (32.7%) started treatment, 15 (6.7%) requested transfer to another health facility, 105 (47.1%) and 30 (13.5%) were lost to follow-up and died respectively without starting ART. The median survival following eligibility for children who died without starting treatment was 2.8?months (IQR: 0.9 - 5.8) with over half (60%) of all deaths occurring at home. ART-eligible children less than 2?years of age and those in WHO stage 3 or 4 were significantly more likely to be LTFU when compared with their respective comparison groups. The overall pre-treatment mortality rate was 25.7 per 100 child-years of follow-up (95% CI 19.9 - 36.8) and the loss to programme rate was 115.7 per 100 child-years of follow-up (95% CI 98.8 - 137). In the multivariable Cox proportional hazard model, significant independent predictors of loss to programme were being less than 2?years of age and WHO stage 3 or 4. The Adjusted Hazard Ratio (AHR) for loss to programme was 2.06 (95% CI 1.12 ?C 3.83) for being aged less than 2?years relative to being 5?years of age or older and 1.92 (95% CI 1.05 - 3.53) for being in WHO stage 3 or 4 relative to WHO stage 1 or 2.

Conclusions

Earlier enrolment into HIV care is key to achieving better outcomes for HIV infected children in developing countries. Developing strategies to ensure early diagnosis, elimination of obstacles to prompt initiation of therapy and instituting measures to reduce losses to follow-up, will improve the overall outcomes of HIV-infected children.  相似文献

Objective

The aim of this study was to determine whether the functional interleukin-6 (IL-6) promoter ?174 G/C and ?572 G/C polymorphisms confer susceptibility to rheumatoid arthritis (RA) in ethnically different populations.

Methods

Meta-analysis was conducted on the associations between these IL-6 polymorphisms and RA.

Results

A total of nine studies involving 3,851 subjects (RA 2,053 and controls 1,798) were considered in this study and ethnicity-specific meta-analysis was performed on European subjects. In all study subjects, meta-analysis revealed a trend toward to an association between RA and the IL-6 ?174 G allele (odds ratio [OR]?=?0.699, 95?% confidence interval [CI]?=?0.463–1.054, p?=?0.088). Stratification by ethnicity indicated a significant association between RA and the IL-6 ?174 G/C polymorphism in Europeans using the dominant (OR?=?0.329, 95?% CI?=?0.155–0.699, p?=?0.004) and recessive (OR?=?0.823, 95?% CI?=?0.679–0.997, p?=?0.047) models. Meta-analysis of the IL-6 ?572 G/C polymorphism showed no association between RA and the IL-6 ?572 G allele in all study subjects (OR?=?1.641, 95?% CI?=?0.613–4.397, p?=?0.324).

Conclusions

This meta-analysis shows that the IL-6 ?174 G/C polymorphism may confer susceptibility to RA in Europeans.  相似文献
