Faith actors and social norms shifting for adolescent health
Across low-and-middle income countries, adolescents navigate social environments where norms shape their opportunities and life trajectories. Faith actors are deeply embedded within these systems and often influence expectations related to communication, sexuality, reproductive health, and marriage. While faith engagement is widely recognized as important for sustainable change, empirical evidence on how faith actors contribute to social norm cha…
Evaluation of postnatal outcomes from a group antenatal care intervention in Nigeria
Background: In previous studies in low- and middle-income countries (LMICs), group antenatal care (gANC) has been shown to increase health facility delivery and enhance the care experience for both women and providers. Here, we investigate whether those benefits lead to improvements in postnatal outcomes. Methods: We examine three time points of data on participation in the gANC programme as an independent variable to predict postnatal mother and…
Norms shifting and behavior change in uncertain times
This commentary reflects on the current state of evidence on social norms interventions focused on improving health and economic outcomes for adolescent girls and young women in low- and middle-income countries. Drawing on a newly published global evidence review, it highlights how the field has evolved from narrow, individual-level strategies toward community-centered approaches. While conceptual clarity and implementation tools have improved, s…
Pathway from Exposure to an E-Cigarette Prevention Social Media Campaign to Increased Quitting Intentions
In 2022, 26-31% of young adults reported using e-cigarettes in the previous 30 days. Research supports the effectiveness of mass media health campaigns in changing targeted attitudes and behaviors regarding nicotine use. However, the effect of social media campaigns and the pathway through which they change attitudes and behaviors require more research. This randomized controlled experiment examines the pathway through which exposure to an e-ciga…

Background: The coronavirus disease 2019 (COVID-19) pandemic has challenged public health and behaviour change programmes, and has led to the development of innovative interventions and research. In low -and middle-income countries (LMICs) such as Nigeria, new strategies to promote vaccination, increase pro-vaccination social norms, and reduce vaccine hesitancy have been deployed through social media campaigns and evaluated using digital media pl…
Implementation and Baseline Evaluation of an Evidence-Based Group Antenatal Care Program in Two Nigerian States
Northern Nigeria has had historically low antenatal care (ANC) utilization rates with poor health outcomes. Previous studies have shown that group antenatal care (gANC) improves ANC behavior and pregnancy outcomes. The gANC has been adopted in Kaduna and Kano States, Nigeria. This paper presents baseline findings from the implementation of the gANC program in Kaduna and Kano States, Nigeria, based on data collected from 1269 and 1200 pregnant wom…
Protocol for Evaluating Remote Patient Blood Pressure Monitoring Adapted to Black Women and Birthing Persons
Cardiovascular disease is the leading cause of maternal death among Black women in the United States. A large, urban hospital adopted remote patient blood pressure monitoring (RBPM) to increase blood pressure monitoring and improve the management of hypertensive disorders of pregnancy (HDP) by reducing the time to diagnosis of HDP. The digital platform integrates with the electronic health record (EHR), automatically inputting RBPM readings to th…
Application of McGuire’s Model to Weight Management Messages

Effects of branded health messages on e-cigarette attitudes, intentions, and behaviors
Strengthening brand equity is an effective strategy for influencing anti-e-cigarette related attitudes and intentions, much like it is for anti-smoking campaigns. More research needs to be done on the relationship between change in brand equity and e-cigarette behavior to better understand how brand equity can be wielded to influence change in e-cigarette use behavior
The Adelante project
There are few models in the literature that provide a roadmap for how to address multiple, related health conditions in marginalized, immigrant communities, even as most health disparities are associated with complex social ecologies. The Adelante intervention adds a useful model of this nature to the evidence base, and provides support for the ecological approach to PYD with respect to such communities. (PsycInfo Database Record (c) 2022 APA, al…

Willingness to Pay for Condoms among Men in Sub-Saharan Africa
HIV/AIDS and other sexually transmitted infections (STIs) continue to be among the greatest public health threats worldwide, especially in sub-Saharan Africa (SSA). Condom use remains an essential intervention to eradicate AIDS, and condom use is now higher than ever. However, free and subsidized condom funding is declining. Research on how to create healthy markets based on willingness to pay for condoms is critically important. This research ha…
Evaluation of Behavior Change Communication Campaigns to Promote Modern Cookstove Purchase and Use in Lower Middle Income Countries
Nearly three billion people worldwide burn solid fuels and kerosene in open fires and inefficient stoves to cook, light, and heat their homes. Cleaner-burning stoves reduce emissions and can have positive health, climate, and women's empowerment benefits. This article reports on the protocol and baseline data from the evaluation of four behavior change communication (BCC) campaigns carried out in lower to middle income countries aimed at promotin…
Adherence to clinical preventive services guidelines
The Patient Protection and Affordable Care Act (ACA) addresses use of clinical preventive services relative to evidence-based guidelines by mandating that most health insurance plans provide coverage without cost-sharing for services that receive an A or B rating. However, knowledge about and positive attitudes towards guidelines are extremely low. This study was a population-based randomized experiment to examine beliefs about and intentions to …

Strength and its relationship to changes in fat-free mass, total body potassium, total body water and IGF-1 in adults with growth hormone deficiency
The present investigation examined changes in strength in growth hormone deficient (GHD) adults following treatment with recombinant human growth hormone (rhGH), and assessed their relationship to changes in fat-free mass (FFM), total body potassium (TBK), total body water (TBW), the concentration of TBK and TBW per kg FFM, and insulin like growth factor-1 (IGF-1). The investigation was double-blind and placebo-controlled for a period of 6 months…
Can media advocacy influence newspaper coverage of tobacco
The presence of an ASSIST main effect should be interpreted with caution because of the quasi-experimental design and the lack of information on article rates before the ASSIST intervention. Nonetheless, these preliminary findings suggest some possible effects of the media advocacy activities of ASSIST when controlling for differences in states' initial tobacco control conditions
