- Family Planning in the Democratic Republic of the Congo: Encouraging Momentum, Formidable Challenges
Formidable challenges: uncertain political situation, cultural norms favoring high fertility, a thin patchwork of service delivery institutions, logistical issues in a vast country with weak infrastructure, and low capacity of the population to pay for contraceptive services. Encouraging progress: increasing government and donor support, openness to progressive service delivery policies, innovative programming including robust social marketing and initiatives with nursing schools and the military, strong collaboration among stakeholders, high unmet need suggesting strong latent demand for family planning, and an increasingly balanced method mix including long-acting methods.
- The Demographic Stretch of the Arc of Life: Social and Cultural Changes That Follow the Demographic Transition
The demographic transition from high to low levels of mortality and fertility brings about changes that stretch the “arc of life,” making each stage of life longer and creating new ones—a phenomenon we call “the demographic stretch.” This stretch can transform societal structure, for example, by extending childhood, shifting working ages up, delaying marriage and childbearing, improving women’s status and equity, and pushing the burden of chronic disease and disability to older ages. Global health efforts must address the resultant economic and social changes.
- mHealth for Tuberculosis Treatment Adherence: A Framework to Guide Ethical Planning, Implementation, and Evaluation
Promising mHealth approaches for TB treatment adherence include:
Video observation
Patient- or device-facilitated indirect monitoring
Direct monitoring through embedded sensors or metabolite testing
To mitigate ethical concerns, our framework considers accuracy of monitoring technologies, stigmatization and intrusiveness of the technologies, use of incentives, and the balance of individual and public good.
- Preventing Peer Violence Against Children: Methods and Baseline Data of a Cluster Randomized Controlled Trial in Pakistan
Peer violence was remarkably high at baseline. Among urban public school students, 94% of 6th-grade boys and 85% of girls reported being victimized by peers in the last 4 weeks. And 85% of boys and 66% of girls reported perpetrating such violence. Boys scored worse on a number of mental health measures. A cluster RCT is underway to evaluate a well-established school-based intervention using sports and games to reduce peer violence.
- Universal Health Coverage in Francophone Sub-Saharan Africa: Assessment of Global Health Experts' Confidence in Policy Options
Even within the fairly homogenous context of francophone Africa, among 18 options presented to experts on how to proceed toward universal health coverage (UHC), consensus was reached on only 1 with respect to effectiveness and another with respect to feasibility. The complexity and challenges of UHC as well as the weak evidence base likely contribute to this uncertainty.
- Meningococcal vaccine introduction in Mali through mass campaigns and its impact on the health system
The meningococcal A vaccine campaign led to major disruption of routine vaccination services and reduced other services, notably antenatal care.
- The State of Digital Interventions for Demand Generation in Low- and Middle-Income Countries: Considerations, Emerging Approaches, and Research Gaps
Despite advances in digital technology to generate demand for health services, considerable gaps remain in our understanding of which interventions are effective, which characteristics mediate their benefit for different target populations and health domains, and what is necessary to ensure effective deployment. Future research should examine the long-term effects of, equity in access to, and cost-effectiveness and efficiency of digital demand generation interventions.
- Evidence-based public health: not only whether it works, but how it can be made to work practicably at scale
Because public health must operate at scale in widely diverse, complex situations, randomized controlled trials (RCTs) have limited utility for public health. Other methodologies are needed. A key conceptual backbone is a detailed “theory of change” to apply appropriate evidence for each operational component. Synthesizing patterns of findings across multiple methodologies provides key insights. Programs operating successfully across a variety of settings can provide some of the best evidence. Challenges include judging the quality of such evidence and assisting programs to apply it. WHO and others should shift emphasis from RCTs to more relevant evidence when assessing public health issues.
- The 6 domains of behavior change: the missing health system building block
Behavior is crucial throughout global health interventions. The discipline of behavior change offers distinct expertise needed across 6 different domains of behavior. Such expertise is in short supply, however. We will not have effective and sustainable health systems, nor achieve our ambitious global health goals, without seriously addressing behavior change.
- A False Dichotomy: RCTs and Their Contributions to Evidence-Based Public Health
Global public health should rely on those research methods that best answer the pressing questions at hand. Randomized controlled trials (RCTs) and other rigorous impact evaluation methods have a critical role to play in public health.
