How Jimmy Osuret Turned Childhood Trauma into Evidence for Safer School Crossings
On a weekday morning in Kampala, the city snarls without any signs of awakening. Cars grind bumper to bumper along crumbling asphalt, their horns locked in a long, impatient argument. Rusting taxis and private vehicles shudder under the rising sun. Boda bodas slice through impossibly narrow gaps, mount pavements, edge past crossings, and assert dominance wherever there is room to move. The road belongs to whoever is bold enough to seize it.
And on the margins of this contest, there are children.
At 6 a.m., long before office doors open, primary school pupils begin their walk. Backpacks bounce against narrow shoulders as they navigate broken sidewalks and dusty road edges. When they reach a main road, their rhythm changes. Some stop and scan, small hands grip the straps. Others hesitate, then dart, misjudging speed, trusting that a driver will slow down.
But traffic rarely slows.
In Kampala, pedestrians do not command the road; they negotiate with it. Every crossing is a calculation. Every pause carries risk. Children learn early that movement requires courage. They watch for gaps, read the body language of drivers, and step forward in faith.
It is in that fragile second, between hesitation and impact, that the question begins to form.
For Jimmy Osuret, this is not an abstract problem of urban mobility but a daily reality, etched into memory long before it became research.
In 1996, as a Primary Four pupil at Shimoni Demonstration School, then located along the busy Nile Avenue corridor in Uganda’s capital, Kampala, he watched a classmate attempt to cross the road on an ordinary school day. A truck did not slow down. The child did not make it to the other side.
“It stayed with me,” Osuret recalls. “At the time, I didn’t have the language for it. But that moment shaped how I came to understand injuries—not as accidents, but as something patterned, preventable, and deeply unfair.”
Nearly three decades later, the school has moved, and the road has changed, but Kampala’s traffic has only grown more unforgiving. Children still gather at pavements across the city, backpacks bouncing, eyes fixed on gaps in traffic that may or may not come. And Osuret would return to these streets, not as a schoolboy navigating danger, but as a public health scientist determined to change what danger looks like for Uganda’s children.
From Personal Loss to Public Health Purpose
Osuret’s journey into injury research unfolded through lived experience, service, and grief, each layer sharpening his understanding of why pedestrian safety matters.
After completing his Bachelor’s degree in Environmental Health at Makerere University, he volunteered with the Uganda Red Cross Society in Bushenyi District between 2009 and 2011. There, he was exposed to emergency response, first aid, and trauma care. Road crashes were no longer statistics but bleeding bodies, panicked families, and systems struggling to respond in time.
“That experience changed how I saw injuries,” he reflects. “They weren’t isolated events. They were predictable outcomes of unsafe systems.”
His MSc in Public Health at Oxford Brookes University deepened that lens. Focusing his dissertation on alcohol-related road traffic injuries, Osuret built strong skills in epidemiology and behavioural research, tools he would later bring back home.
But it was personal loss that cemented his resolve. A cousin was killed in a hit-and-run crash. Another reminder that vulnerability on Uganda’s roads often carries the highest cost.
Together, these experiences shaped the research question that would define his PhD: Why are Kampala’s roads so unsafe for children, and what actually works to protect them?
Kampala’s Roads, Through a Child’s Eyes
Every day, millions of Ugandans walk to school, to work, to markets, to taxi stages. At some point in the day, everyone becomes a pedestrian. For children, walking is not a choice; it is the only option. Yet Kampala’s roads tell children they do not belong.
Rapid urbanisation and motorisation have transformed the city, but road design continues to privilege vehicles over people. Sidewalks are missing or obstructed. Safe crossings are rare. Speed control is weak. Children are forced to negotiate fast-moving traffic despite their limited ability to judge speed and distance.
Osuret’s research confirms what many parents already fear. Pedestrians account for more than a third of road casualties in Uganda, with children bearing a disproportionate share of that burden. Unsafe crossing behaviours, running, failing to stop at the pavement, and weaving between vehicles are not acts of carelessness. They are survival strategies in hostile environments.
“Children are expected to behave safely in systems that are fundamentally unsafe,” he explains. “That is not reasonable, and it is not ethical.”
Watching the Road Tell Its Story
Rather than relying on self-reports or simulations, Osuret turned to the road itself. Using discreetly mounted video cameras at school crossings across Kampala, his team observed thousands of real interactions between children, vehicles, and the built environment. The footage captured moments of hesitation, confusion, urgency, and occasionally, near misses that left the researchers gasping for air.
His findings were sobering. One in five children failed to wait at the pavement. More than a quarter crossed outside marked crosswalks. Many ran. Some crossed between vehicles, often when drivers failed to yield.
“These behaviours are not random,” Osuret notes. “They respond directly to what drivers do and what the road allows.”
Crucially, the data revealed something else: where trained school traffic wardens were present, children behaved differently, and drivers did too.
The Power of a Raised Hand
Osuret’s PhD went beyond observation. It tested a solution.
In a cluster-randomized trial across 34 public primary schools, his team introduced a school traffic warden behavioural promotion programme, a low-cost intervention placing trained adult wardens at school crossings during peak hours. The wardens wore reflective gear, used stop paddles, made eye contact with drivers, and guided children through safe crossing routines: stop, look, wait, walk.
Strikingly, drivers were more than seven times more likely to yield to child pedestrians where a traffic warden was present. Children were 70% more likely to cross safely, stopping at the pavement, walking instead of running, and avoiding dangerous gaps between vehicles.
“What surprised me most,” Osuret recalls, “was how quickly children adapted. When the system supported them, safer behaviour became the norm.”
The intervention faced some resistance. Some drivers ignored wardens. Others were openly hostile. These moments revealed a deeper truth that behaviour change cannot rely on goodwill alone. It requires enforcement, legitimacy, and policy backing.
Behaviour Is Not the Problem—Systems Are
A central insight of Osuret’s work is that road safety debates often focus on the wrong actor.
“Children are told to be careful,” he says. “But children are not the ones designing roads, setting speed limits, or enforcing laws.”
His research shows that driver behaviour, especially yielding and speed, has a direct protective effect on children. Higher driver-yielding rates are consistently associated with fewer pedestrian collisions. Behaviour change among drivers is therefore not optional but foundational.
This perspective aligns with the Safe Systems Approach, which recognises human error as inevitable and places responsibility on systems to prevent fatal outcomes. In Kampala, where infrastructure and enforcement gaps are stark, behavioural interventions like traffic wardens offer an immediate, scalable bridge, especially in school zones.
Scholarship Grounded in Community
Osuret’s academic home at Makerere University School of Public Health shaped how his research evolved. Mentorship from senior injury researchers at Makerere University grounded his work in rigorous methods and local relevance.
“I worked closely with Dr. Olive Kobusingye at the Trauma, Injury, and Disability Unit and became involved in research on pedestrian road safety through international collaborations. Makerere taught me to ask questions that matter here,” he says. “Not just what is publishable, but what is usable.”
That grounding helped him navigate the most challenging phase of his PhD, especially balancing full-time academic work, research, and personal responsibilities. Like many African scholars, he conducted much of his doctoral research while teaching, mentoring, and engaging communities.
“It made me deeply aware of the structural barriers young researchers face,” he reflects. “And it strengthened my commitment to mentorship.”
From Evidence to Action
On January 10, 2025, Osuret publicly defended his PhD in a hybrid session at the Makerere University School of Public Health Auditorium. The defense was both a scholarly milestone and a personal reckoning, a moment when decades of memory, loss, and inquiry converged.
But for Osuret, the PhD was never an endpoint.
Today, he serves on the National Road Safety Committee, contributing evidence to Uganda’s National Road Safety Action Plan. He mentors students, collaborates with policymakers, and continues to argue, persistently, that injuries deserve the same public health urgency as infectious diseases.
“The gap is not knowledge,” he says. “We know what works. The gap is translating evidence into action.”
If policymakers took just one lesson from his research, “design roads around children, not vehicles,” he says. Osuret believes that speed management, safe crossings, and visible enforcement around schools are essential obligations, not luxuries.
Walking Toward Safer Futures
As the country prepares for the 76th Makerere University Graduation Ceremony this February 2026, where Osuret and 184 others will receive their PhDs, we are reminded of what scholarship can do when it remains rooted in lived reality.
Every day, children still gather on the road pavements outside schools like Shimoni. Traffic still hums, and risk has not disappeared. But in some places, a raised hand, a reflective vest, and a trained presence have shifted the balance, if only slightly, toward safety.
When asked what responsibility he now carries, Osuret does not hesitate.
“To ensure that evidence informs decisions,” he says. “Because at some point in the day, we are all pedestrians. And no one should have to gamble with their life just to cross the road.”

Adolescence is a consequential period for health, when diets, behaviours and other risks can form and persist into adulthood. In Mayuge District, new evidence from Makerere University School of Public Health is showing how some of these early vulnerabilities could contribute to the later risk of non-communicable diseases (NCDs), and what can change when interventions begin early.
The evidence comes from the ARISE-NUTRINT project, a three-year EU-funded study led by Prof. David Guwatudde and Dr. Justine Bukenya. The project examines health and behavioural risks among adolescents and young adults, with a particular focus on nutrition-related NCD risks, and tests interventions designed to improve nutrition fluency and diet quality.
The work comes against a substantial NCD burden in a country where 73.2% of the population is below 30. WHO estimates that NCDs accounted for 42.2% of deaths in Uganda in 2023, while the country’s latest national NCD risk-factor survey found significant risk factors persisting in the population, with little overall change from the previous survey in 2014. Together, the evidence strengthens the case for prevention much earlier in life.
“There is strong evidence from literature demonstrating that most behavioral NCD risk factors, including nutrition-related, are established during childhood, persisting into adulthood. This may lead to development of actual NCDs if such risks are not reversed early,” Prof. Guwatudde said.
The study, he explained, linked assessment of young people’s health risks with developing responses suited to their circumstances. Since enrolling 1,206 participants aged 10–24 in Mayuge District in March 2024, the team has conducted three annual rounds of data collection, with young people and local stakeholders also helping evaluate interventions to reduce the risks identified.
A problem that starts early
The findings, shared with community and district stakeholders in Iganga on October 1, 2026, show that some vulnerabilities were already evident at baseline. Nearly one in three participants had anaemia, 49% had low nutrition literacy, while about one in ten reported symptoms of anxiety and a similar proportion reported depressive symptoms.
Anaemia, a condition in which the blood does not have enough healthy red blood cells or haemoglobin to carry adequate oxygen around the body, was highest among the youngest participants. Overall, 375, or 31%, had anaemia, rising to 35.7 per cent among 10–14-year-olds, compared with 18.9% among those aged 15–19 and 10.6 per cent among young adults aged 20–24.
Nutrition presented another challenge. At baseline, 49% of participants had low nutrition literacy and 13% had poor overall diet quality. Low nutrition literacy was associated with more than four times the odds of poor diet quality.
Gaps also emerged in sexual and reproductive health knowledge and behaviour. About 14 per cent of participants did not know that HIV cannot be transmitted by sharing food with a person living with HIV, 10% believed a condom could be used more than once, and 13 per cent did not know pregnancy could occur during first sexual intercourse. Among 168 participants who reported having had sex, more than half reported using no method to prevent pregnancy during their first or most recent sexual intercourse.
Mental health findings added another dimension. Anxiety symptoms were reported by 10 per cent of participants, depressive symptoms by 9.5% and loneliness by 6.3 per cent. Among 534 participants aged 13–24 assessed for suicidal ideation, 1.9% reported suicidal thoughts.
Together, the baseline findings show that vulnerabilities extended beyond any single health issue. For nutrition, the study went further to examine what shaped everyday food choices and whether those influences could be changed.
Nutrition literacy goes beyond knowing which foods are healthy. It includes understanding nutrition information and applying it to everyday choices. The study found those choices were also shaped by parents, peers, food vendors, culture, prices, seasons, and what was available locally. Improving diets, therefore, required reaching beyond individual knowledge to the households and communities where food choices are made.
What early action changed
The baseline evidence informed the Adolescent Nutrition Fluency Intervention. Working with adolescents and young adults, caregivers, Community Health Workers (CHWs), district teams and other stakeholders, the project adapted nutrition messages to local foods, language and household realities. Ten trained CHWs delivered nine monthly household sessions covering balanced diets, physical activity, vitamins and minerals, meal planning and anaemia prevention.
The household approach reached young people in and out of school. The nutrition literacy, diet-quality and intervention analyses form part of the PhD research of Mr. Thomas Buyinza, supported through ARISE-NUTRINT. At endline, participants who received the sessions recorded higher nutrition literacy and overall diet-quality scores.
“The improvement in nutrition literacy and diet quality suggests that practical education, grounded in local foods and household realities, can support healthier choices among adolescents and young adults. In addition, involving parents and caregivers is important because they influence what families buy, prepare, and eat,” Dr. Bukenya said.
She stressed that nutrition education needed to be complemented by better access to affordable, nutritious foods. Dr. Bukenya also called for continued follow-up, including the use of nutrition and dietary data from DHIS2, to assess whether improvements were maintained and guide district planning.
Changes in other outcomes were mixed. Participants reporting no physical activity fell from 22.6% to 7.4%, while those active on four to seven days a week increased from 46% to 54.8%. But activity duration did not improve: those reporting more than 60 minutes a day declined from 28.2% to 21.1%. Underweight fell modestly from 6.2% to 5%, while overweight and obesity did not change significantly.
Anaemia recorded the largest change, falling from 31.1% before the intervention to 9.9% afterwards. During the intervention period, participants received weekly iron and folic acid supplementation and deworming alongside nutrition education on iron-rich foods, dietary diversity and practices that improve iron absorption.
Mayuge District’s Assistant District Health Officer, Ms. Elizabeth Kawaala, said the findings reflected problems recognised locally and highlighted the need for a response involving families and other stakeholders.
“There is a serious challenge that needs to be tackled with many stakeholders, with parents at the centre because these are children. We also learnt that many parents, I think, lack the skills to communicate with their adolescents,” she said.
She said the findings had been shared with colleagues and described integrating health education and sensitisation into services. She also called for departments to use the evidence when planning activities in their workplans.
Beyond Mayuge
Seen alongside Uganda’s 2023 STEPS survey, the Mayuge findings add an earlier-life dimension to the national evidence. Makerere University School of Public Health contributed to both studies, with Prof. Guwatudde contributing to the national STEPS survey and now leading ARISE-NUTRINT. While STEPS found significant NCD risk factors persisting among adults, ARISE-NUTRINT shows that some behaviours and vulnerabilities relevant to later NCD risk are already evident during adolescence and young adulthood. The Mayuge research goes further by testing what can change when interventions begin during this period.
The findings leave Mayuge with more than a measure of the problem. They show where vulnerabilities are emerging, what changed when interventions were introduced and where challenges remain. For ARISE-NUTRINT, the evidence now turns attention to which approaches can be sustained and how lessons from Mayuge can inform efforts to support healthier transitions from adolescence into adulthood.
