Effects of prenatal lead, mercury, cadmium, and arsenic exposure on children’s neurodevelopment in an artisanal small-scale gold mining area in Northwestern Tanzania using a multi-chemical exposure mo…
An estimated 250 million children under five fail to reach their cognitive development potential in Africa. Growing evidence suggests reduced neurodevelopments for children from environmental exposures, yet research on this topic in Sub-Saharan Africa remains limited. This study examined the effects of multi-chemical prenatal exposure to heavy metals on developmental milestones for children aged 3–4 in artisanal and small gold mining areas in nor…

A retrospective study of congenital anomalies and associated risk factors among children admitted at a tertiary hospital in northwestern Tanzania
Congenital anomalies in Sub-Sahara Africa (SSA) are understudied despite the significant pediatric health burden. This retrospective longitudinal hospital-based study evaluated the records of 326 inpatient children under the age of two years with congenital anomalies at Bugando Medical Centre, a tertiary referral hospital in northwestern Tanzania. Classical logistic regression was used in the analysis of congenital malformation of muscles, gastro…
Perceived occupational health risks, noise and dust exposure levels among street sweepers in Mwanza City in Northern Tanzania
Solid waste has been a major problem particularly in Sub-Saharan Africa countries as it has been increasing in several years. One of the methods employed in solid waste management is street sweeping which is done by street sweepers. Street sweepers are being predisposed to respiratory and non-respiratory infection like eye infection, skin infection and musculoskeletal disorders. This analytical cross-sectional study enrolled a total of 233 street…
The role of geophagy and artisanal gold mining as risk factors for elevated blood lead levels in pregnant women in northwestern Tanzania
Neither artisanal and small-scale gold mining (ASGM) or geophagy practices have received substantial attention related to blood lead levels despite the well documented deleterious effects of lead. This cross-sectional analytical study aimed to document the risk of lead exposure from geophagy and mining-related occupational activities for pregnant women. The study recruited 1056 pregnant women (883 in an ASGM area and 173 in a non-ASGM area) betwe…
Informal welders’ occupational safety and environmental health risks in northwestern Tanzania
Often with minimal formal training and protections, informal welders face significant occupational health and safety (OSH) risks. This cross-sectional study of 219 adult informal welders at 70 informal welding sites in Mwanza City, Tanzania aimed to: 1) capture knowledge and awareness of occupational risks and safety precautions, training, and self-reported work-related injuries and illness and 2) observe worker use of personal protective equipme…
Influence of intermittent iron and folic acid supplementation on cognitive abilities among adolescent girls in northwestern Tanzania
Iron and folic acid (IFA) supplementation to reduce anemia is key for improving substantial lost disability adjusted life years (DALYs) for adolescent girls. This study assessed the impact of weekly IFA supplementation (WIFAS) on cognitive ability among adolescent girls in the Simiyu Region in northernwestern Tanzania. This cross-sectional comparative evaluation study of 770 adolescent girls (396 –WIFAS supplemented; 374 –not supplemented) evalua…
Challenges in accessing health care and socio-protection services among children living and working in streets in northwestern Tanzania
The escalating number of Children Living and Working in Streets (CLWS) in Tanzania has become one of the neglected Public Health issues. It is of more concern that, most of the CLWS hardly have access to health care and socio-protection services as a result, increase their vulnerability to infections and engagement in risky behaviors such as early unprotected sex. Currently, efforts by Civil Society Organizations (CSOs) to work with and assist CL…
Spatial distribution of suspected and confirmed cholera cases in Mwanza City, Northern Tanzania
Cholera, which is caused by Vibrio cholerae , persists as a devastating acute diarrheal disease. Despite availability of information on socio-cultural, agent and hosts risk factors, the disease continues to claim lives of people in Tanzania. The present study explores spatial patterns of cholera cases during a 2015–16 outbreak in Mwanza, Tanzania using a geographical information system (GIS) to identify concentrations of cholera cases. This cross…
Disability inclusion in malaria services in western Tanzania
The findings of this study identify that malaria intervention stakeholders need to take a holistic approach and fully involve individuals with disabilities at all levels and scope of malaria service planning and provision
Biological, material and socio-cultural constraints to effective menstrual hygiene management among secondary school students in Tanzania
Menstrual hygiene management is an important determinant for girls’ educational outcomes. We develop a method of cross-sectional analysis that quantifies the relative importance of four distinct mechanisms: material, biological, social and informational constraints and consider four main schooling outcomes: absenteeism, early departure, concentration and participation. We use survey data from 524 female students enrolled in four co-educational se…
Water Scarcity and Water Quality
Bottom-up public health interventions are needed which are built on an understanding of community perspectives. Project SHINE is a community-based participatory action research intervention focused on developing sustainable water, sanitation, and hygiene strategies with Maasai pastoralists in Tanzania. The aim of the study is to understand perceptions related to water quality and scarcity as well as to assess the potential of the Biosand Filter a…
Investigating the association between stress. Anxiety and geophagy among pregnant women in mwanza, Tanzania
Understanding environmental, health and economic activity interactions following transition of ownership in gold mining areas in Tanzania
Mining is an important source of revenue for many developing countries, however, the social, environmental and economic impacts of mining are often poorly monitored. The recent transition of a gold mine in Western Tanzania—from large-scale gold mine under private, multinational ownership, to medium-scale public and national owned mine with limited life length offers a prime opportunity to understand the implications of changes in ownership and sc…
