Sex workers and the cost of safe sex - the compensating differential for condom use in Calcutta

The practice of safe sex by commercial sex workers is considered central to preventing the transmission of AIDS in developing countries. The authors estimate the compensating differential for condom use among sex workers in Calcutta, based on results from a survey conducted in 1993. If, as suggested by anecdotal evidence, this loss in income is large, it would indicate the existence of strong disincentives for practicing safe sex. To identify the relationship between condom use and the average price per sex act, they follow an instrumental variable approach, exploiting an intervention program focused on providing information about the AIDS virus and about safe sex practices. The program, instituted in 1992, was not systematically administered. Using this method, they found that sex workers who always use condoms face a loss of 79 percent in the average earnings per sex act.Gender and Health,Adolescent Health,Health Monitoring&Evaluation,Reproductive Health,HIV AIDS

Source Apportionment of PM10 by Positive Matrix Factorization in Urban Area of Mumbai, India

Particulate Matter (PM10) has been one of the main air pollutants exceeding the ambient standards in most of the major cities in India. During last few years, receptor models such as Chemical Mass Balance, Positive Matrix Factorization (PMF), PCA–APCS and UNMIX have been used to provide solutions to the source identification and contributions which are accepted for developing effective and efficient air quality management plans. Each site poses different complexities while resolving PM10 contributions. This paper reports the variability of four sites within Mumbai city using PMF. Industrial area of Mahul showed sources such as residual oil combustion and paved road dust (27%), traffic (20%), coal fired boiler (17%), nitrate (15%). Residential area of Khar showed sources such as residual oil combustion and construction (25%), motor vehicles (23%), marine aerosol and nitrate (19%), paved road dust (18%) compared to construction and natural dust (27%), motor vehicles and smelting work (25%), nitrate (16%) and biomass burning and paved road dust (15%) in Dharavi, a low income slum residential area. The major contributors of PM10 at Colaba were marine aerosol, wood burning and ammonium sulphate (24%), motor vehicles and smelting work (22%), Natural soil (19%), nitrate and oil burning (18%)

Examining adherence and sexual behavior among patients on antriretroviral therapy in India

"Very high levels of patient adherence (greater than 95 percent) are required for antiretroviral therapy (ART) to be effective and to prevent the emergence of resistant viral strains (Paterson et al. 2000; Ickovics et al. 2002). Since 1997, antiretroviral (ARV) medications have been available in India through the private sector and some employer-supported health insurance programs. It is estimated that India has 5.1 million HIV-infected persons (NACO 2004), some of whom have been on ART for several years. However, very little information is available on the levels of adherence to ART among people living with HIV/AIDS in India. With increased availability of ART, HIV-positive individuals are living healthier lives and continuing or resuming sexual activity. But, optimism related to ART's success in slowing disease progression, reducing viral load, and improving health status may lead to more risky sexual practices and a possible increase in transmission of infections. Determining the sexual behavior of HIV-positive persons on ART is therefore an area of special interest and concern. To meet these knowledge gaps, the Horizons Program, in collaboration with research partners in Delhi and Pune, conducted a study to assess current levels of adherence to ART among a sample of people living with HIV/AIDS, identify the factors that influence their adherence to treatment, and determine their sexual risk behaviors. The study also examined the economic burden of ART on the household. Findings from the study provide important insights that are immediately relevant to the scale-up of the national ART program, which was launched in April 2004." [OCLC Accession No.: 70645391

Socioeconomic inequality in life expectancy in India

Introduction Concern for health inequalities is an important driver of health policy in India; however, much of the empirical evidence regarding health inequalities in the country is piecemeal focusing only on specific diseases or on access to particular treatments. This study estimates inequalities in health across the whole life course for the entire Indian population. These estimates are used to calculate the socioeconomic disparities in life expectancy at birth in the population. Methods Population mortality data from the Indian Sample Registration System were combined with data on mortality rates by wealth quintile from the National Family Health Survey to calculate wealth quintile specific mortality rates. Results were calculated separately for males and females as well as for urban and rural populations. Life tables were constructed for each subpopulation and used to calculate distributions of life expectancy at birth by wealth quintile. Absolute gap and relative gap indices of inequality were used to quantify the health disparity in terms of life expectancy at birth between the richest and poorest fifths of households. results Life expectancy at birth was 65.1 years for the poorest fifth of households in India as compared with 72.7 years for the richest fifth of households. This constituted an absolute gap of 7.6 years and a relative gap of 11.7 %. Women had both higher life expectancy at birth and narrower wealth-related disparities in life expectancy than men. Life expectancy at birth was higher across the wealth distribution in urban households as compared with rural households with inequalities in life expectancy widest for men living in urban areas and narrowest for women living in urban areas. Conclusion As India progresses towards Universal Health Coverage, the baseline social distributions of health estimated in this study will allow policy makers to target and monitor the health equity impacts of health policies introduced

Examining adherence and sexual behavior among patients on antiretroviral therapy in India

CLINICAL EVALUATION OF COMPARATIVE AND COMBINED EFFECT OF POLYHERBAL MICROBICIDE (BASANT) AND SELECTED PROBIOTICS IN THE TREATMENT OF RECCURRENT VAGINOSIS - A PHASE II PLACEBO CONTROLLED TRIAL

Background: Vaginosis is a widely prevalent syndrome in women. Treatment with one or more antibiotics cures invariably the infections. However recurrence is frequent and pH of the vagina is not always restored to the normal acidic range. This trial was conducted to determine whether a Polyherbal Microbicide BASANT or three selected strains of Probiotics Lactobacilli alone or the two in combination can regress Vaginosis, bring down the vaginal pH to acidic range and restore healthy vagina with colonised Lactobacilli.Methods: Women suffering from recurrent episodes of vaginosis were given capsules of either BASANT, Probiotics, Combination of the two or Placebo capsules for insertion in vagina for 7 nights. On day 10, Pelvic examination, pH, Whiff test, Gram stain for Clue cells and swab taken for culture of lactobacilli.Results: BASANT regressed Vaginosis in 14/ 20, Probiotics in 13/20, Combination of the two in 19/ 20 women and Placebo in 1/ 20 women.Conclusion: While both Polyherbal microbicide BASANT and the three strains of the lactobacilli cured Vaginosis in 65 to 70% of women, the combination was highly effective in curing 95% of women

Reducing AIDS-related stigma and discrimination in Indian hospitals

People living with HIV/AIDS in India, as elsewhere, face stigma and discrimination in a variety of contexts. Research in India has shown that stigma and discrimination against HIV-positive people and those perceived to be infected are common in hospitals and act as barriers to seeking and receiving critical treatment and care services. Recognizing the need to move beyond documentation of the problem, three New Delhi hospitals; SHARAN, an Indian NGO; and the Horizons program, with support from the National AIDS Control Organisation (NACO), carried out an operations research project to develop and test responses to hospital-based stigma and discrimination against people living with HIV/AIDS. This report presents the findings which noted that despite variation among the hospitals in their action plan accomplishments, overall the intervention process was associated with improvements among healthcare workers in HIV knowledge, attitudes toward people living with HIV/AIDS, and certain practices with respect to HIV counseling and testing and confidentiality

Reducing stigma and discrimination in hospitals: Positive findings from India

People living with HIV (PLHIV) in India face stigma and discrimination in a variety of contexts. Stigma and discrimination against HIV-positive people is common in hospitals and acts as a barrier to seeking and receiving critical treatment and care services. Three New Delhi hospitals, SHARAN, and the Horizons Program collaborated on an operations research project to assess responses to hospital-based stigma and discrimination against PLHIV. A baseline survey to measure HIV/AIDS-related attitudes, knowledge, and practices was conducted in 2000 with a random sample of 884 health workers from four departments: medicine, STD and skin, obstetrics and gynecology, and surgery. Based on this assessment, hospital managers and senior representatives of doctors, nurses, and ward staff developed action plans to improve the situation. As noted in this research summary, hospital managers who used a checklist to assess their facilities’ policies and practices took action to improve staff safety and reduce AIDS-related stigma. Findings suggest that the actions taken, including education, training, policy formulation, and involvement of AIDS NGOs, contributed to improved knowledge, attitudes, and practices among health workers

Pulsars as Fantastic Objects and Probes

Pulsars are fantastic objects, which show the extreme states of matters and plasma physics not understood yet. Pulsars can be used as probes for the detection of interstellar medium and even the gravitational waves. Here I review the basic facts of pulsars which should attract students to choose pulsar studies as their future projects.Comment: Invited Lecture on the "First Kodai-Trieste Workshop on Plasma Astrophysics", Kodaikanal Obs, India.

The Structural Relationship Between Current and Capital Account Balance in India: A Time Series Analysis

The long run relationship between current account balance (CAB) and capital account balance (KAB) and the repercussions of capital account convertibility (KAC) on growth process of a country is a much debated issue. In particular, in the aftermath of the Southeast Asian crisis, the limitation of the liberal capital regime for a developing country like India is often highlighted in the literature. However, the probable impact of introducing KAC on CAB in India generally is discussed theoretically. Though some of the existing studies in India have earlier focused on this research question, they have done so by exogenously assuming the existence of a single structural break in the interrelationship between CAB and KAB. The present study intends to bridge the gap in the literature by raising two empirical questions: first, how far KAC is likely to destabilize the CAB and second, measuring the strength of the interrelationship between CAB and KAB. The current paper also contributes to the literature by incorporating multiple endogenous structural breaks in the empirical analysis. The empirical findings do not support any long term relationship between capital and current account balance and reveals that two significant structural breaks are observed in 1993-94 and 2003-04
