In 2003, Nigeria adopted the Family Life and HIV Education (FLHE) sexuality education curriculum. Our analysis interrogates variation in sub-national implementation. We conducted 52 interviews with persons knowledgeable about the curriculum in three states-Kano, Lagos, and Niger-and reviewed publications on FLHE. In Kano, the socio-cultural context impeded implementation, but the persistence of innovative local champions resulted in some success. In Lagos, the cosmopolitan context, effective champions, funding by international donors, and a receptive government bureaucracy led to successful implementation. In Niger, despite a relatively conservative socio-cultural context, state bureaucratic bottlenecks overwhelmed proponents' efforts. In summary, the interaction of socio-cultural context, domestic champions, adaptive capacity of state bureaucracies, and international funders explains variable implementation of FLHE. The Nigerian experience highlights the need for sexuality education proponents to anticipate and prepare for local opposition and bureaucratic barriers.

Community health workers (CHWs) are frequently put forward as a remedy for lack of health system capacity, including challenges associated with health service coverage and with low community engagement in the health system, and expected to enhance or embody health system accountability. During a ‘think in’, held in June of 2017, a diverse group of practitioners and researchers discussed the topic of CHWs and their possible roles in a larger “accountability ecosystem.” This jointly authored commentary resulted from our deliberations. While CHWs are often conceptualized as cogs in a mechanistic health delivery system, at the end of the day, CHWs are people embedded in families, communities, and the health system. CHWs’ social position and professional role influence how they are treated and trusted by the health sector and by community members, as well as when, where, and how they can exercise agency and promote accountability. To that end, we put forward several propositions for further conceptual development and research related to the question of CHWs and accountability.

BackgroundThere exists no consistent explanation for why some countries are successful in combating HIV/AIDS and others are not, and we need such an explanation in order to design effective policies and programmes. Research evaluating HIV interventions from a biomedical or public health perspective does not always take full account of the historical and organizational characteristics of countries likely to influence HIV outcomes. The analysis in this paper addresses this shortcoming by testing the impact of organizational and structural factors, particularly those resulting from population interventions, on HIV outcomes at the country level in sub-Saharan Africa.MethodsThe primary independent variables are factors that originated from efforts to slow population growth: whether a country has a long-time affiliate of the International Planned Parenthood Federation and whether a country has a population policy. Additional structural factors likely to impact HIV outcomes include the level of wealth, the level of cultural fractionalization, and the former colonial power. The present study uses multivariate regression techniques with countries in sub-Saharan Africa as the unit of analysis, and four measures of success in addressing HIV: the change in prevalence between 2001 and 2009; the change in incidence between 2001 and 2009; the level of overall antiretroviral coverage in 2009; and the level of antiretroviral coverage for prevention of vertical transmission in 2009.ResultsCountries with the greatest declines in HIV prevalence and incidence had older International Planned Parenthood Federation affiliates and had adopted population policies, even after controlling for age of epidemic, level of antiretroviral coverage, and funding for HIV. Population policies are also important predictors of levels of overall antiretroviral coverage and of coverage of HIV-positive pregnant women to prevent vertical transmission. Structural factors with significant impacts include wealth, cultural fractionalization and former colonial power.ConclusionsThe organizational and structural context of African countries is strongly predictive of HIV outcomes. This finding implies that policy and programmatic efforts should be put towards strengthening existing organizations and perhaps even creating new ones. The fact that cultural fractionalization also influences HIV outcomes suggests that efforts must be put towards identifying ways to reach political consensus in diverse societies.

BackgroundProponents have promoted sexuality education as a means of empowering adolescents, yet it has been thwarted in many low and middle-income countries. Nigeria represents an exception. Despite social opposition, the government in 1999 unexpectedly approved sexuality education policy. Since then, implementation has advanced, although efficacy has differed across states. We draw on theory concerning international norm diffusion to understand Nigerian policy development.ResultsWe find that a confluence of international and national norms and interests shaped policy outcomes, including concern over HIV/AIDS. A central dynamic was an alliance of domestic NGOs and international donors pressing the Nigerian government to act.ConclusionsWe argue that theory on international norms can be applied to understand policy dynamics across a variety of health and population areas, finding value in approaches that integrate rather than juxtapose consideration of (1) international and national influences; (2) long and short-term perspectives on policy change; and (3) norms and interests.

The topic modeling algorithm works by using the observed frequency of the distribution of terms in the document to predict the distribution of terms in a topic. i Structural topic modeling incorporates information about the document (metadata) into the distributions of terms; in other words, the algorithm 'uses' information about each document (in this case, the year in which it was written) to assign words into topics. ii
