Transforming Parkinson's Care in Africa (TraPCAf): protocol for a multimethodology National Institute for Health and Care Research Global Health Research Group project.

BACKGROUND: Parkinson's disease (PD) is the second most common neurodegenerative disorder and, according to the Global Burden of Disease estimates in 2015, was the fastest growing neurological disorder globally with respect to associated prevalence, disability, and deaths. Information regarding the awareness, diagnosis, phenotypic characteristics, epidemiology, prevalence, risk factors, treatment, economic impact and lived experiences of people with PD from the African perspective is relatively sparse in contrast to the developed world, and much remains to be learned from, and about, the continent. METHODS: Transforming Parkinson's Care in Africa (TraPCAf) is a multi-faceted, mixed-methods, multi-national research grant. The study design includes multiple sub-studies, combining observational (qualitative and quantitative) approaches for the epidemiological, clinical, risk factor and lived experience components, as appropriate, and interventional methods (clinical trial component). The aim of TraPCAf is to describe and gain a better understanding of the current situation of PD in Africa. The countries included in this National Institute for Health and Care Research (NIHR) Global Health Research Group (Egypt, Ethiopia, Ghana, Kenya, Nigeria, South Africa and Tanzania) represent diverse African geographies and genetic profiles, with differing resources, healthcare systems, health and social protection schemes, and policies. The research team is composed of experts in the field with vast experience in PD, jointly led by a UK-based and Africa-based investigator. DISCUSSION: Despite the increasing prevalence of PD globally, robust data on the disease from Africa are lacking. Existing data point towards the poor awareness of PD and other neurological disorders on the continent and subsequent challenges with stigma, and limited access to affordable services and medication. This multi-site study will be the first of its kind in Africa. The data collected across the proposed sub-studies will provide novel and conclusive insights into the situation of PD. The selected country sites will allow for useful comparisons and make results relevant to other low- and middle-income countries. This grant is timely, as global recognition of PD and the public health challenge it poses builds. The work will contribute to broader initiatives, including the World Health Organization's Intersectoral global action plan on epilepsy and other neurological disorders.

Postpartum depression and child growth in Tanzania: a cohort study.

OBJECTIVE: To examine the association between postpartum depression and child growth in a Tanzanian birth cohort. DESIGN: Prospective cohort study. SETTING: Moshi, Tanzania. POPULATION: Pregnant women over the age of 18 who sought antenatal care at two health clinics in Moshi, and the children they were pregnant with, were assessed for inclusion in this study. METHODS: The women were interviewed twice during pregnancy and three times after birth, the final follow up taking place 2-3 years postpartum. Signs of postpartum depression were assessed approximately 40 days postpartum with the Edinburgh Postnatal Depression Scale. MAIN OUTCOME MEASURES: Child growth was assessed with anthropometric measurements at 2-3 years of age and expressed as mean z-scores. RESULTS: In all, 1128 mother-child pairs were followed throughout the duration of the study. In total, 12.2% of the mothers showed signs of postpartum depression. Adjusted mean height-for-age z-score (HAZ) was significantly lower at 2-3 years follow up for children of mothers with postpartum depression than for children of mothers without (difference in HAZ: -0.32, 95% CI-0.49 to -0.15). Adjusted mean weight-for-height z-score (WHZ) was significantly increased for the children exposed to postpartum depression (difference in WHZ: 0.21, 95% CI 0.02-0.40), whereas there was no significant difference in adjusted weight-for-age z-score (WAZ; difference in WAZ: -0.04, 95% CI -0.20 to 0.12). CONCLUSIONS: We found that postpartum depressive symptoms predicted decreased linear height in children at 2-3 years of age and slightly increased weight-for-height. TWEETABLE ABSTRACT: Postpartum depression in Tanzanian mothers is associated with impaired child growth at 2-3 years of age.
