HIV and STI Prevalence and Determinants among Male Migrant Workers in India

Background

Our objective was to estimate for the first time the prevalence and determinants of human immunodeficiency virus type 1 (HIV-1) and sexually transmitted infections (STIs) among male migrants in India.

Methodology/Principal Findings

We conducted a multi-stage stratified probability sample survey of migrant (defined as not born in Surat city) men aged 18 to 49 years working in the diamond and textile industries in Surat city. Behavioural and biological data were collected. Biological data included laboratory diagnosed herpes simplex virus type 2 (HSV-2), syphilis, chlamydia, gonorrhoea, Trichomonas vaginalis (together defined as ‘any STI’) and HIV-1. Likely recently acquired STIs included chlamydia, gonorrhoea, T.vaginalis and syphilis with rapid plasma reagin ≥1∶8. The response rate was 77% (845/1099). Among 841 participants, HIV-1 prevalence was 1.0%, ‘any STI’ prevalence was 9.5% and 38.9% of these STIs were likely to have been recently acquired. Being a diamond worker, Surat resident for 10+ years and recent antibiotic use were each associated with higher odds of ‘any STI’ (aORs 1.83 (95% CI 1.09–3.09), 1.98 (95% CI 1.22–3.22) and 2.57 (95% CI 1 .17–5.64), respectively) after adjusting for the other two factors and age. The main study limitation was social desirability bias for self-reported sexual behaviour; STIs were diagnosed in some self-reported virgins.

Conclusions/Significance

HIV and STI prevalence were lower than expected, but prevention interventions remain necessary in Surat since almost 40% of STIs among participants were probably recently acquired and sentinel surveillance HIV prevalence remains high. The participants had a similar HIV prevalence to Surat antenatal clinic attendees, a proxy for the general population. This suggests migrants are not always at higher risk of HIV compared to the general population in their migration destination. Our findings highlight the need to contextualise research findings from a specific setting with other local information to guide HIV/STI prevention interventions.     

Lymphoedema management knowledge and practices among patients attending filariasis morbidity control clinics in Gampaha District, Sri Lanka

BACKGROUND: Little information is available on methods of treatment practiced by patients affected by filarial lymphoedema in Sri Lanka. The frequency and duration of acute dematolymphangioadenitis (ADLA) attacks in these patients remain unclear. This study reports the knowledge, practices and perceptions regarding lymphoedema management and the burden of ADLA attacks among patients with lymphoedema. METHODS: A semi-structured questionnaire was used to assess morbidity alleviation knowledge, practices and perceptions. The burden of ADLA attacks was assessed using one-year recall data. RESULTS: 66 patients (22 males, 44 females) with mean age 51.18 years (SD +/- 13.9) were studied. Approximately two thirds of the patients were aware of the importance of skin and nail hygiene, limb elevation and use of footwear. Washing was practiced on a daily and twice daily basis by 40.9% and 48.5% respectively. However, limb elevation, exercise and use of footwear were practiced only by 21-42.4% (while seated and lying down), 6% and 34.8% respectively. The majority of patients considered regular intake of diethylcarbamazine citrate (DEC) important. Approximately two thirds (65.2%) had received health education from filariasis clinics. Among patients who sought private care (n = 48) the average cost of treatment for an ADLA attack was Rs. 737.91. Only 18.2% had feelings of isolation and reported community reactions ranging from sympathy to fear and ridicule. CONCLUSIONS: Filariasis morbidity control clinics play an essential role in the dissemination of morbidity control knowledge. Referral of lymphoedema patients to morbidity control clinics is recommended.     

Reaching impaired populations with HIV prevention programs: a clinical trial for homeless mentally ill African-American men.

This study tested an intervention to reduce sexual risk behaviors in a high risk impaired population: homeless African-American, Caucasian and Hispanic men with mental illness. In a comparison group clinical trial, men were assigned to an experimental cognitive-behavioral or a control intervention and followed up over 16 months. Men were recruited from a psychiatric program in two shelters for homeless men in Nashville, Tennessee. An ethnically mixed cohort of subjects (54% African-American, 42% Caucasian and 4% Hispanic) were included in the study. Most had a chronic psychiatric disorder and a co-morbid substance abuse disorder. The 257 participants who were sexually active (130 experimental, 127 control) prior to the trial were the main target of the intervention. An experimental intervention (SexG), adapted from Susser and Associates (51), comprised 6 group sessions. The control intervention was a 6-session HIV educational program. Sexual risk behavior was the primary outcome. The experimental and control groups were compared with respect to the mean score on a sexual risk index. Complete follow-up data were obtained on 257 men (100%) for the initial six-month follow-up. These individuals have been followed for the remainder of the 16-month follow-up. This intervention, (SexG), successfully reduced sexual risk behaviors of homeless mentally ill African-American, Caucasian and Hispanic men. Similar approaches may be effective in other impaired high-risk populations.

Prevalence of excessive or problem drinkers among patients attending somatic outpatient clinics: a study of alcohol related medical care.

The prevalence of alcohol related morbidity was studied among 2038 patients attending somatic outpatient clinics. A further 76 patients had refused the study, giving an overall drop out rate of 3.6%. Several methods were combined so as to detect as many patients with problem drinking as possible. According to the criteria and definitions employed 17% of men (confidence interval 15% to 19%) and 4% of women (confidence interval 3% to 5%) were excessive consumers of alcohol or problem drinkers. The highest proportion of such patients--that is, 17%--was noted in the emergency rooms (27% of men, 8% of women). At other clinics the proportions varied from 11% to 17% of men and from 2% to 4% of women. The strongest relations between overconsumption of alcohol and consultation at the clinic were among patients attending the medical outpatient clinic and the emergency rooms; in 86% (confidence interval 75% to 97%) and 88% (confidence interval 81% to 95%) of problem drinkers attending these clinics, respectively, alcohol was related to the consultation. Consultations were related to alcohol in 82% of women with excessive or problem drinking and 73% of men defined in this way. There was a tendency to a higher proportion of men with excessive or problem drinking in the age group 40-49 years. These findings show that among patients classified as excessive or problem drinkers attending somatic outpatient clinics there was a close relation between alcohol consumption and utilisation of medical resources, especially in women.     

Knowledge of prosthodontic treatment among denture-wearers and non-denture-wearers attending a dental institute in India: a survey report

Objective: Knowledge of subjects regarding prosthodontic treatment may play a role in their acceptance of the prostheses. The purpose of this survey was to assess the knowledge of prosthodontic treatment among the denture‐wearers and non‐denture‐wearers reporting to the Institute of Dental Sciences, Belgaum. Methods: A self‐designed closed‐ended questionnaire containing 14 questions was designed. Four‐hundred and nineteen subjects aged between 25 and 65 years were surveyed over a period of 2 months. Collected data were statistically analysed using chi‐squared test at a significance level of p < 0.05. Results: From the 419 subjects surveyed, 140 subjects (33.4%) were dentate and 279 subjects (66.6%) were edentulous either in the maxillary, mandibular or both arches. Among the 279 edentulous subjects, 143 (51.3%) did not use any kind of prosthesis. There was a statistically significant difference in knowledge regarding the replacement of teeth by artificial means, the number of visits required for the provision of a complete denture, problems with dentures among subjects using and not using them (p < 0.001) whereas no significant difference was found among the subjects regarding aesthetics with dentures and socializing with friends. Conclusion: Attempts should be made to raise the level of knowledge of both denture‐wearers and non‐denture‐wearers reporting to the Institute for any dental treatment.     

Contraceptive knowledge,attitudes and use among women attending health clinics in St. Petersburg,Russian Federation

This study describes women's knowledge, attitudes, and use of contraception in Russia. Data were obtained from a sample of 917 women attending 44 women's consulting centers in St. Petersburg during January 15-30, 1995. Findings indicate that 68% were married; 21% were single. 56.1% worked full-time, 7.2% worked part-time, and 9.4% were students. 50.9% reported having received sex education, of whom 73.8% learned about birth control methods and 70.7% learned about abortion. Over 90% of the entire sample knew about condoms, IUDs, and oral contraceptives. About 60-70% knew about rhythm, withdrawal, and female sterilization. 49-56% were aware of vaginal suppositories and vasectomy. Under 23% were aware of the diaphragm, sponge, jelly, and foam. People talked about family planning with doctors and partners. 58.7% preferred joint responsibility for family planning. 909 women responded to the question about the current method being used: 41% reported using condoms; 33.8%, IUDs; 32.8%, pills; 23.7%, the rhythm method; and 17.2%, withdrawal. Many women used multiple methods, but the questions did not clearly distinguish single from concurrent multiple method use or switching between a few methods. 20.6% report nonuse. 115 of 187 were pregnant or desiring a pregnancy. Nonusers were concerned about side effects. Method choice was based on effectiveness and ease of use. Few were dissatisfied with their method choice. About 75% reported method switching over time. Most of the 452 oral contraceptive users knew 2-3 side effects. 25.1% of the 319 condom users were usual users.     

Somatoform disorders among patients attending walk-in clinics in Trinidad: prevalence and association with depression and anxiety

Objectives Somatoform disorders are common in international primary care settings, but have been little studied in the developing world. The objective of this study was to determine the prevalence of severe undifferentiated somatoform disorder, and its relationship to depression and anxiety, among patients attending walk-in clinics in Trinidad.Methods The study participants, who were all aged 18 years or older and attending walk-in clinics at 16 randomly selected health centres, were surveyed between May and August 2007 using the PRIME-MD questionnaire.Results There were 594 participants (the response rate was 92%), of whom 72.7% were female. Their ages ranged from 18 to 93 years, and 54.5% were over 50 years of age. In total, 37.2% were married and 25.9% were single. Indo-Trinidadians represented 43.1% and Afro-Trinidadians represented 36% of the study sample; 56.5% of the participants reported that their income was less than US$ 400 per month, and 65.7% were unemployed. At walk-in clinics in Trinidad, the estimated prevalence of severe undifferentiated somatoform disorder was 10.3% (95% CI: 7.86–12.74), that of hypochondriasis was 28.5% (95% CI: 24.9–32.1), and that of body dysmorphic disorder was 15.8% (95% CI: 11.9–18.7). Severe undifferentiated somatoform disorder was statistically significantly associated with gender and ethnicity but not with age, level of education, employment status or income. Chi-square testing found significant associations between the presence of severe undifferentiated somatoform disorder and both depression and anxiety (P < 0.05), between hypochondriasis and both anxiety and depression (P < 0.05), and between body dysmorphic disorder and depression (P < 0.05) but not anxiety. Regression analysis suggested that the demographic features that predicted severe undifferentiated somatoform disorder were being female or Indo-Trinidadian.Conclusions Walk-in clinics in Trinidad that serve older patients on a lower income have a high proportion of patients with somatoform disorders as measured by the PRIME-MD scale. These patients exhibit many features of anxiety and depression. These findings have implications for medical training and service delivery.     

Caring for Caregivers of People Living with HIV in the Family: A Response to the HIV Pandemic from Two Urban Slum Communities in Pune,India

Introduction

In low resource settings, the vast majority of ‘Person/people Living with HIV’ (PLHIV/s) and inadequate healthcare delivery systems to meet their treatment and care needs, caregivers play a vital role. Home based caregivers are often unrecognized with limited AIDS policies and programs focusing on them. We explored the perceptions and norms regarding care being provided by family caregivers of PLHIVs in India.

Methodology

A community based qualitative study to understand the issues pertaining to home based care for PLHIV was conducted in urban settings of Pune city, in Maharashtra, India. Eight Focus Group Discussions (FGDs) among men, women and peer educators were carried out. A total of 44 in-depth Interviews (IDIs) with PLHIVs (20) and their caregivers (24), were conducted using separate guides respectively. Data was analyzed thematically.

Results

Home based care was perceived as economically viable option available for PLHIVs. ‘Care’ comprised of emotional, adherence, nursing and financial support to PLHIV. Home based care was preferred over hospital based care as it ensured confidentiality and patient care without hampering routine work at home. Women emerged as more vital primary caregivers compared to men. Home based care for men was almost unconditional while women had no such support. The natal family of women also abandoned. Their marital families seemed to provide support. Caregivers voiced the need for respite care and training.

Discussion

Gender related stigma and discrimination existed irrespective of women being the primary family caregivers. The support from marital families indicates a need to explore care and support issues at natal and marital homes of the women living with HIV respectively. Home based care training and respite care for the caregivers is recommended. Gender sensitive interventions addressing gender inequity and HIV related stigma should be modeled while designing interventions for PLHIVs and their family caregivers.     

HIV incidence among men who have sex with men in China: a meta-analysis of published studies

Background

Men who have sex with men (MSM) have now become one of the priority populations for prevention and control of HIV pandemic in China. Information of HIV incidence among MSM is important to describe the spreading of the infection and predict its trends in this population. We reviewed the published literature on the incidence of HIV infection among MSM in China.

Methods

We identified relevant studies by use of a comprehensive strategy including searches of Medline and two Chinese electronic publication databases from January 2005 to September 2010. Point estimate of random effects incidence with corresponding 95% confidence intervals (CI) of HIV infection was carried out using the Comprehensive Meta-Analysis software. Subgroup analyses were examined separately, stratified by study design and geographic location.

Results

Twelve studies were identified, including three cohort studies and nine cross-sectional studies. The subgroup analyses revealed that the sub-overall incidence estimates were 3.5% (95% CI, 1.7%–5.3%) and 6.7% (95% CI, 4.8%–8.6%) for cohort and cross-sectional studies, respectively (difference between the sub-overalls, Q = 5.54, p = 0.02); and 8.3% (95% CI, 6.9%–9.7%) and 4.6% (95% CI, 2.4%–6.9%) for studies in Chongqing and other areas, respectively (difference between the sub-overalls, Q = 7.58, p<0.01). Syphilis infection (RR = 3.33, p<0.001), multiple sex partnerships (RR = 2.81, p<0.001), and unprotected receptive anal intercourse in the past six months (RR = 3.88, p = 0.007) represented significant risk for HIV seroconversion.

Conclusions

Findings from this meta-analysis indicate that HIV incidence is substantial in MSM in China. High incidence of HIV infection and unique patterns of sexual risk behaviors in this population serve as a call for action that should be answered with the innovative social and public health intervention strategies, and development of biological prevention strategies.     

Integrating prevention of mother-to-child HIV transmission programs to improve uptake: a systematic review

Background

We performed a systematic review to assess the effect of integrated perinatal prevention of mother-to-child transmission of HIV interventions compared to non- or partially integrated services on the uptake in low- and middle-income countries.

Methods

We searched for experimental, quasi-experimental and controlled observational studies in any language from 21 databases and grey literature sources.

Results

Out of 28 654 citations retrieved, five studies met our inclusion criteria. A cluster randomized controlled trial reported higher probability of nevirapine uptake at the labor wards implementing HIV testing and structured nevirapine adherence assessment (RRR 1.37, bootstrapped 95% CI, 1.04–1.77). A stepped wedge design study showed marked improvement in antiretroviral therapy (ART) enrolment (44.4% versus 25.3%, p<0.001) and initiation (32.9% versus 14.4%, p<0.001) in integrated care, but the median gestational age of ART initiation (27.1 versus 27.7 weeks, p = 0.4), ART duration (10.8 versus 10.0 weeks, p = 0.3) or 90 days ART retention (87.8% versus 91.3%, p = 0.3) did not differ significantly. A cohort study reported no significant difference either in the ART coverage (55% versus 48% versus 47%, p = 0.29) or eight weeks of ART duration before the delivery (50% versus 42% versus 52%; p = 0.96) between integrated, proximal and distal partially integrated care. Two before and after studies assessed the impact of integration on HIV testing uptake in antenatal care. The first study reported that significantly more women received information on PMTCT (92% versus 77%, p<0.001), were tested (76% versus 62%, p<0.001) and learned their HIV status (66% versus 55%, p<0.001) after integration. The second study also reported significant increase in HIV testing uptake after integration (98.8% versus 52.6%, p<0.001).

Conclusion

Limited, non-generalizable evidence supports the effectiveness of integrated PMTCT programs. More research measuring coverage and other relevant outcomes is urgently needed to inform the design of services delivering PMTCT programs.     

A review of trachoma history in China: research,prevention, and control

Trachoma is one of the most widespread blinding eye diseases, which is harmful to human visual health. The efforts to prevent and control trachoma in China can be divided into three periods, i.e., highly epidemic period, research on pathogenesis and control of trachoma, and blinding trachoma elimination and epidemiological evaluation. In 1956, Prof. Feifan Tang and Xiaolou Zhang first discovered and isolated Chlamydia trachomatis, which clarified the cause of trachoma, and kick-started a fresh chapter in trachoma research, prevention, and control around the world. Although, the prevalence of trachoma differed in different areas, the average prevalence once exceeded 50% and was as high as 90% in some areas before and at early liberation of China. Therefore, the government-led efforts were made to comprehensively prevent and control trachoma, including development of National Plan for the Prevention and Control of Trachoma, nationwide screening and treatment of trachoma, implementation of National Patriotic Health Campaign and improvement of water supply and lavatories. After decades of effort, China reached the goal of eliminating blinding trachoma in 2015. China has gained remarkable achievements in the prevention and treatment of trachoma, making outstanding contributions toward the goal of eliminating trachoma worldwide. The research, prevention, and control of trachoma in China were reviewed in this paper.     

Infection with HIV and hepatitis C virus among injecting drug users in a prevention setting: retrospective cohort study

Objectives: To estimate the incidence of HIV and hepatitis C virus and risk factors for seroconversion among a cohort of injecting drug users. Design: Retrospective cohort study. Setting: Primary healthcare facility in central Sydney. Subjects: Injecting drug users tested for HIV-1 antibody (n=1179) and antibodies to hepatitis C virus (n=1078) from February 1992 to October 1995. Main outcome measures: Incidence of HIV-1 and hepatitis C virus among seronegative subjects who injected drugs and underwent repeat testing. Demographic and behavioural risk factors for hepatitis seroconversion. Results: Incidence of HIV-1 among 426 initially seronegative injecting drug users was 0.17/100 person years (two seroconversions) compared with an incidence of hepatitis C virus of 20.9/100 person years (31 seroconversions) among 152 injecting drug users initially negative for hepatitis C virus. Incidence of hepatitis C virus among injecting drug users aged less than 20 years was 75.6/100 person years. Independent risk factors for hepatitis C virus seroconversion were age less than 20 years and a history of imprisonment. Conclusions: In a setting where prevention measures have contributed to the maintenance of low prevalence and incidence of HIV-1, transmission of hepatitis C virus continues at extremely high levels, particularly among young injecting drug users.

Key messages

• The prevalence and incidence of hepatitis C virus is high, while the prevalence and incidence of HIV remains low among injecting drug users
• Young age and history of imprisonment are risk factors for acquisition of hepatitis C virus infection
• HIV prevention strategies have been relatively ineffective in preventing hepatitis C virus infection in this population
• The role of imprisonment in the acquisition of hepatitis C infection should be further investigated

     

HIV and syphilis co-infection increasing among men who have sex with men in China: a systematic review and meta-analysis

Background

This study aims to estimate the magnitude and changing trends of HIV, syphilis and HIV-syphilis co-infections among men who have sex with men (MSM) in China during 2003–2008 through a systematic review of published literature.

Methodology/Principal Findings

Chinese and English literatures were searched for studies reporting HIV and syphilis prevalence among MSM from 2003 to 2008. The prevalence estimates were summarized and analysed by meta-analyses. Meta-regression was used to identify the potential factors that are associated with high heterogeneities in meta-analysis. Seventy-one eligible articles were selected in this review (17 in English and 54 in Chinese). Nationally, HIV prevalence among MSM increased from 1.3% during 2003–2004 to 2.4% during 2005–2006 and to 4.7% during 2007–2008. Syphilis prevalence increased from 6.8% during 2003–2004 to 10.4% during 2005–2006 and to 13.5% during 2007–2008. HIV-syphilis co-infection increased from 1.4% during 2005–2006 to 2.7% during 2007–2008. Study locations and study period are the two major contributors of heterogeneities of both HIV and syphilis prevalence among Chinese MSM.

Conclusions/Significance

There have been significant increases in HIV and syphilis prevalence among MSM in China. Scale-up of HIV and syphilis screening and implementation of effective public health intervention programs should target MSM to prevent further spread of HIV and syphilis infection.     

Morbidity and risk of subsequent diagnosis of HIV: a population based case control study identifying indicator diseases for HIV infection

Background

Early identification of persons with undiagnosed HIV infection is an important health care issue. We examined associations between diseases diagnosed in hospitals and risk of subsequent HIV diagnosis.

Methods

In this population-based case control study, cases were persons with incident HIV infection diagnosed in Denmark between 1 January 1995 and 1 June 2008. Risk-set sampling was used to identify 19 age- and gender-matched population controls for each HIV case, using the HIV diagnosis date as the index date for both cases and controls. Prior hospital diagnoses obtained from Danish medical databases were first categorized into 22 major disease categories (excluding AIDS-defining diseases except tuberculosis) and then subdivided into 161 subcategories, allowing us to examine specific diseases as potential HIV indicators by conditional logistic regression.

Results

The study included 2,036 HIV cases and 35,718 controls. Persons with the following disease categories had a high risk of HIV diagnosis during the subsequent 5-year period: sexually transmitted infections and viral hepatitis (adjusted odds ratio [aOR] = 12.3, 95% CI: 9.60–15.7), hematological diseases (aOR = 4.28, 3.13–5.85), lower respiratory tract infections (aOR = 3.98, 3.14–5.04)), CNS infections (aOR = 3.44, 1.74–6.80), skin infections (aOR = 3.05, 2.47–3.75), other infections (aOR = 4.64, 3.89–5.54), and substance abuse (aOR = 2.60, 2.06–3.29). Several specific diseases were associated with aORs >20 including syphilis, hepatitis A, non “A” viral hepatitis, herpes zoster, candida infection, endocarditis, thrombocytopenia, and opioid abuse.

Conclusions

Targeted testing for HIV in patients diagnosed with diseases associated with HIV may lead to earlier treatment and thereby reduced morbidity, mortality and HIV transmission.
