The impact of the national polio immunization campaign on levels and equity in immunization coverage: evidence from rural North India

Few studies have investigated the impact of immunization campaigns conducted under the global polio eradication program on sustainability of polio vaccination coverage, on coverage of non-polio vaccines (administered under Expanded Program on Immunization (EPI)), and on changes in social inequities in immunization coverage. This study proposes to fill the gaps in the evidence by investigating the impact of a polio immunization campaign launched in India in 1995. The study uses a before-and-after study design using representative samples from rural areas of four North Indian states. The National Family Health Survey I (NFHS I) and NFHS II, conducted in 1992-93 and 1998-99 respectively, were used as pre- and post-intervention data. Using pooled data from both the surveys, multivariate logistic regression models with interaction terms were used to investigate the changes in social inequities. During the study period, a greater increase was observed in the coverage of first dose of polio compared to three doses of polio. Moderate improvements in at least one dose of non-polio EPI vaccinations, and no improvements in complete immunization against non-polio EPI diseases were observed. The polio campaign was successful, to some extent, in reducing gender-, caste- and wealth-based inequities, but had no impact on religion- or residence-based inequities. Social inequities in non-polio EPI vaccinations did not reduce during the study period. Significant dropouts between first and third dose of polio raise concerns of sustainability of immunization coverage under a campaign approach. Similarly, little evidence to support synergy between polio campaign and non-polio EPI vaccinations raises questions about the effects of polio campaign on routine health systems functions. However, moderate success of the polio campaign in reducing social inequities in polio coverage may offer valuable insights into the routine health systems for addressing persistent social inequities in access to health care.

Attitudes Toward Wife Beating A Cross-Country Study in Asia

Using demographic and health surveys conducted between 1998 and 2001 from seven countries (Armenia, Bangladesh, Cambodia, India, Kazakhstan, Nepal, and Turkey), the study found that acceptance of wife beating ranged from 29% in Nepal, to 57% in India (women only), and from 26% in Kazakhstan, to 56% in Turkey (men only). Increasing wealth predicted less acceptance of wife beating, except in Cambodia and Nepal. Higher education level was negatively associated with acceptance in Turkey and Bangladesh. Younger respondents justified wife beating more often, with some exceptions, showing persistent intergenerational transmission of gender norms. Working women were equally or more likely to justify wife beating compared to nonworking women. Men were significantly more likely to justify wife beating in Armenia, Nepal, and Turkey. Targeted proactive efforts are needed to change these norms, such as improving female literacy rates and other enabling factors.

CHILD IMMUNIZATION IN VIETNAM: SITUATION AND BARRIERS TO COVERAGE

This paper addresses the overall performance and inequalities in the immunization of children in Vietnam. Descriptive and logistic analysis of cross-national demographic and health data was used to examine inequality in immunization, identify the most vulnerable groups in immunization coverage, and identify the gap in coverage between hard-to-access people and the remainder of the population. The gap in the coverage was found to occur primarily in vulnerable groups such as the poor minority or poor rural children. No evidence was found of a difference in immunization coverage because of sex or birth order. However, the age of children showed a significant influence on the rate of immunization. Mothers education and regular watching of television had a significant influence on child immunization. In order to improve child immunization coverage in Vietnam, efforts should be concentrated on poor children from minority groups and those living in rural areas, especially remote ones. Community development, investment for immunization and re-organization of immunization services at the grassroots level are also key factors to remove the barriers to immunization for vulnerable populations in Vietnam.

Transformational trends confounding the South Asian health systems

Already overwhelmed by the burden of communicable diseases, the health systems in South Asia face six global and regional transformational trends, which pose opportunities, challenges and threats. These six trends discussed in the paper are: (i) economic growth and globalization; (ii) technological changes; (iii) labor market changes; (iv) private sector growth; (v) demographic changes; and (vi) epidemiological changes. These trends have created dual challenges for the health systems in South Asia: (i) to achieve the Millennium Development Goals (MDGs) relating to child and maternal health, and communicable diseases and (ii) to deal with the emerging challenges posed by the six transformational trends. The paper suggests and proposes the use of the transformational trends framework to investigate the various opportunities and challenges, and to design effective policy responses. The capacities and resources of the governments in the region are already stretched by legacy challenges posed by communicable diseases. Hence, effective responses to new challenges will need flexible and innovative approaches including partnership with private sector, civil society, and regional cooperation. The opportunities from the trends are more likely to benefit the richer sections of the society. Therefore, pro-poor measures are necessary to ensure inclusive development.

South Asia, Health Systems of

The South Asia region comprises eight countries – Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka. As a region, South Asia has the second worst health indicators after sub-Saharan Africa, and the worst in malnutrition. In the last decade, almost all the South Asian countries have achieved some gains in terms of improved life-expectancy and control of communicable diseases. Almost all South Asian countries achieved some gains in terms of life expectancy, reduction of maternal, infant and under-five mortality, though the progress made is variable. Private out-of-pocket health expenditures remain the dominant model of health financing, despite some efforts by some countries to introduce social health insurance schemes in recent years. Unregulated and largely informal private health sectors provide most of the health services, especially curative care. The public health system is generally weak and services are of varying quality. With the ongoing demographic and epidemiological transitions, these weak health systems will confront new challenges.
