The earliest years of life, particularly from birth to age 3, represent a critical window for brain development, characterized by plasticity and sensitivity to environmental influences, both positive and negative. If foundational skills are not adequately nurtured during this sensitive period, children may face a permanent loss of developmental potential. This can lead to long-term negative consequences across the life course, including lower educational attainment, reduced social mobility, limited economic achievement, and poorer health outcomes. One of the aims of the Sustainable Development Goals is to increase the proportion of children under 5 years of age who are developmentally on track in terms of health, learning, and psychosocial well- being.

The mental health of health care workers (HCWs) is an important global concern, particularly in low- and middle-income countries (LMICs) such as Kenya, where unique stressors may place HCWs at disproportionate risk for depression.1 However, depression prevalence and risk factors in this population are not well understood. To address this gap, we evaluated the prevalence of depressive symptoms among Kenyan HCWs and identified associated demographic, psychological, and workplace factors.

Mental health disorders among adolescents and young adults in Africa are a growing concern, with most cases remaining undiagnosed or untreated due to limited resources. As the youth population increases, mental health issues are expected to rise, emphasising the need for targeted interventions. However, the lack of longitudinal data hinders researchers from understanding how social, behavioural, and clinical factors interact, which is essential for developing effective interventions. This study aimed to create a mental health data resource accessible to mental health researchers across Africa.

This study explored the effectiveness of open-source generative models in generating realistic, privacy-preserving synthetic datasets of a Health and Demographic Surveillance System (HDSS) dataset obtained from rural Kenya, as a proof of concept for low- and middle-income countries (LMICs). Using 3 open-source models—CTGAN, TableGAN, and CopulaGAN—synthetic data were created from the real data while maintaining important characteristics like missing values and outliers. The quality of the synthetic data was evaluated to determine whether it maintained the statistical properties present in the real data and provided privacy protection. Among the models tested, CTGAN performed the best, producing synthetic data that closely resembled the real data while preserving data privacy. In contrast, CopulaGAN and TableGAN were less successful, with TableGAN completely failing to generate realistic synthetic data. This study shows that CTGAN can be a valuable tool for creating synthetic data in LMICs, making real datasets more accessible and preserving privacy.


Community engagement (CE) has been recommended as an important ethical consideration for health research to enhance informed consent and exchange knowledge between researchers and community members. The purpose of this paper is to describe how CE was developed and delivered for the PRECISE prospective pregnancy cohort study in Kenya. PRECISE enrolled pregnant women in antenatal care, followed them up to the postpartum period, and collected data and biological samples to enable the study of placental disorders in sub-Saharan Africa.
