Rising Childhood Obesity: Mak Researchers Investigate Unhealthy Food and Beverage Advertising to Children
By Joseph Odoi
In Uganda, many children are exposed to aggressive advertisement of unhealthy foods and sugar sweetened non-alcoholic beverages which in turn prepares their mind as future potential clients. Unfortunately, there is little understanding on the extent, nature and impact of children’s exposure to food and non-alcoholic beverage advertising trends in Uganda.
Driven by this worrying trend and increasing non-communicable diseases (NCDs), researchers at Makerere University have embarked on a study to promote regulated unhealthy food and sugar sweetened beverage advertising.
A research project titled Food and beverage Advertising to Children in Uganda(FACe-U), with funding from Makerere University Research and Innovations Fund (MakRIF), has been commissioned to understand advertising patterns of unhealthy foods and non-alcoholic beverages towards children below 18 years. This study comes at a time when there’s coinciding increase in overweight and obesity cases among children in Uganda. The project will also investigate the extent to which content influences children’s food choices and suggest changes for more responsible food and beverage advertising. This will contribute towards creating a healthy food environment in Uganda.
According to Dr. Gloria Seruwagi, the Project lead and Principal Investigator, young children are gaining more weight early, mostly because of the foods they eat, pushed by advertising.“We are seeing an increase in waist size. Children are becoming more obese and overweight mostly because of the foods that they consume, the lifestyles we are allowing them as parents and caretakers. This brings complications to children which may affect their overall development and academic performance. We need to protect impressionable children and adolescents. Recently the World Health Organisation through the Global RECAP program and engagement of policymakers in Uganda, confirmed that ‘marketing restrictions to children’ is a number one priority issue in Uganda. We need to support global and national effort to strengthen capacity of key actors in promoting healthy diets and increase physical activity for the prevention of NCDs.
We hope that our study findings will inform and support policy actions to regulate irresponsible production and advertising; create healthy food environments that prevent childhood obesity; and contribute towards achieving the Uganda Nutrition Action Plan II (2020-2025) and the country’s Strategic Development Goals” she remarked. This study is foundational and shall begin by undertaking a situation analysis. For example; we shall assess how often unhealthy food and beverages adverts feature on TV, the airing period (at what time), how many times, and the persuasive content targeting children and adolescents.” she added. The study will use empirical and media monitoring data to determine trends of magnitude of advertising and types of food and non-alcoholic beverages advertised to children in Uganda.
According to the Study Co-PI Florence Tushemereirwe, this one year study is a partnership between a team of researchers at Makerere University School of Public Health(MakSPH) and the School of Social Sciences (CHUSS). The project team also includes Maureen Nabatanzi (Research Fellow), Dr. Priscilla Cheptyo (Research Officer), Maria Ssematiko and Flavia Nakacwa (Project Liason and Administrator respectively).The team has mentors based at MakSPH, APHRC in Nairobi, Sciencano and Institute of Tropical Medicine, in Belgium.
Expected Outcomes of Face-U Project
- Increased understanding on the nature and extent of food and non-alcoholic beverages advertising to children. We shall use real time television, radio and newspaper data, including video clips and pictures where appropriate, to generate this outcome.
- Categories of food and non-alcoholic beverages advertised to children using the AFRO nutrient profile model. Categorizing the types of food and beverages advertised shows the nature of food advertised to influence children’s food choices and diets.
- Analysis and documentation of the persuasive techniques used to promote food and sweetened beverages to children and children’s preferred media channels. Food and non-alcoholic beverages advertisers use content to persuade children and capture innocent children’s minds early in life to prepare them as future clients for their products. This outcome will directly contribute towards food and beverage regulation – specifically on marketing to children in Uganda.
In her remarks, Florence Basiimwa Tushemerirwe, a public health nutritionist and Co-Principal Investigator of the project said the study will be implemented in Mbale, Kabale, Kampala and the surrounding areas. Ms. Tushemerirwe said that the team chose study sites like Kabale owing to the fact that it’s a meeting place for more than 3 countries; e.g. Uganda , Rwanda, Burundi and DRC Congo. Mbale district receives products from South Sudan and Kenya. The Kampala Metropolitan area represents urban settings with higher exposure to advertising among children, partly due to TV access and billboard adverts among others.
Dr. Cheputyo Priscilla, a member of the research team, gave insight into how Uganda is currently undergoing a nutrition transition with many children becoming overweight and obese, according to national data.Obesity is caused by many factors but the most common is consumption of foods that are high in calories. “We get most of the calories from sweet sugars, added to processed foods like sodas, yogurts and baked products in the supermarkets; we get calories from fatty foods like chips, fried foods like chicken, chaps, rolex, and more from fast food restaurants,” she explained.Florence Tushemereirwe, the Study Co-PI from Makerere University School of Public Health makes a point
National Obesity Statistics
In 2016, Uganda Demographic and Health Survey (UDHS) found: 4% of children under five years, and 16% of adolescent girls were obese, a rise from 2.4% of boys and 2.1% of girls in 2014. Therefore, it is the right time for Uganda to nip these health conditions in the bud.

Makerere Hosts Inaugural Falling Walls Lab Competition as Innovators Pitch Solutions to National Challenges
Students and researchers from Makerere University and other institutions pitched 12 innovations addressing challenges in healthcare, clean energy, agriculture, waste management and community resilience during the inaugural Falling Walls Lab Kampala, held at the School of Public Health Auditorium, Makerere University.
The competition brought together emerging innovators to present solutions to practical challenges through a three minute pitch, followed by questions from a panel of judges.
Modelled on the Falling Walls format that originated in Berlin, the event required each participant to identify a “wall” a problem or barrier, and demonstrate how their innovation seeks to break it down.
Mudhasi wins with newborn jaundice screening device
Andrew Mudhasi of Makerere University emerged as the overall winner with a score of 90 per cent for a low cost medical device designed to improve newborn jaundice screening across different skin tones.
Mudhasi explained that the device uses optical sensor technology and a skin tone targeting algorithm to provide a rapid reading, with the aim of helping nurses and clinicians identify jaundice more efficiently.
During questions from the jury, Mudhasi said the device had not yet been tested on actual babies but had undergone laboratory testing using simulated skin tones.
He reported an accuracy rate of 94 per cent when the device was compared with laboratory spectrophotometers.
The innovation is intended initially for use in clinics and hospitals, with Mudhasi saying the team is also considering a version that could eventually allow mothers to screen babies at home.
Mudhasi’s innovation has previously received recognition at the African Business Concept Challenge and the iF Design Student Award, according to his presentation.
Rhonda’s innovation tackles diaper waste
Rhoda John of the University of Nairobi emerged in second place with 89.6 per cent for an innovation addressing the problem of used diaper waste.
Under the theme “Breaking the wall of diaper waste and drug soils,” Rhonda explained that her team extracts sodium polyacrylate, the absorbent polymer found in diapers, and replaces the sodium with potassium.
The resulting potassium based superabsorbent material is designed to act as a “water battery” in soil by absorbing and retaining water for plants during dry periods.
John said testing showed a 99 per cent increase in germination and a 23 per cent increase in drought resistance.
The innovation also seeks to reduce the amount of used diapers ending up in landfills and the environmental effects associated with their decomposition.
During the question and answer session, John explained that her team was working with government environmental officials in Nairobi on a pilot collection system to address the challenge of gathering used diapers at scale.
Mahera takes third place with herbal peptic ulcer treatment
Stuart Mahera of Makerere University finished third with 86.2 per cent for a herbal formulation targeting peptic ulcers.
Presenting under the theme “Breaking the wall of Nature and Modern Medicine,” Mahera argued that conventional treatment for peptic ulcers can involve multiple medicines and may be associated with side effects and antimicrobial resistance.
His proposed formulation, MARAC capsules, is intended as a monotherapy, combining properties required for peptic-ulcer treatment in a single capsule.
Mahera said his team had carried out quality control work, including characterisation and dose quantification, and had conducted preclinical trials on laboratory mice.
He also told the jury that an application had been submitted to the National Drug Authority as the team awaits the next stage of the regulatory process.
According to Mahera, the proposed seven day treatment would cost about Shs21,000, compared with the existing 14 day treatment approach.
Innovators present solutions to practical challenges
The remaining presentations covered a wide range of challenges.
Esther Nakungu of Utamu University presented Agri-Track, a digital record keeping solution intended to improve visibility, accountability and management of farm operations and financial information.
Dr. Jimmy Chachiga, a Makerere University participant, presented a solar photovoltaic cooker with a heat storage system designed to provide a cleaner and more reliable cooking option during both sunny and non sunny periods.
His presentation focused on reducing dependence on biomass fuels and addressing the challenges associated with intermittent solar energy.
Abdul Noor Luttamaguzi, a PhD student and senior government fisheries officer, presented a mobile application aimed at helping fish farmers and extension officers report, track and manage disease outbreaks.
Henry Duke Tamale presented a herbal cream targeting antibiotic resistant biofilm infections associated with diabetic foot ulcers.
Marvin Seruwu proposed adapting existing near infrared brain monitoring technology to help detect extra-axial brain bleeds in health facilities where access to CT and MRI equipment is limited.
His proposal seeks to repurpose existing technology towards a diagnostic need that could be particularly important in settings where advanced imaging facilities are not readily available.
Kennedy Kisame presented a poultry alert and diagnosis system combining satellite weather information with computer vision disease detection. The proposed system could be accessed through a smartphone application, SMS or USSD, making it potentially usable by farmers with limited internet access.
Frank Atwiine proposed a solar powered mobile diagnostic van designed to bring ultrasound and other diagnostic services closer to rural communities.
Johnson Makmot, a software and blockchain developer, presented a platform that combines GPS tracking and blockchain-based tokens to incentivise and verify plastic-waste collection in Kampala.
Dr. Nelson Ndugu, from a partner university, presented an artificial intelligence tool designed to translate agricultural research publications into local Ugandan languages and generate voice notes for radio-based extension delivery.
The final presentation came from Dr. Juliet Akola, a Ugandan post doctoral researcher at Mangosuthu University of Technology in South Africa.
Akola presented a community digital resilience initiative focused on mapping risks in Kampala’s informal settlements, including flooding, fire, poor sanitation, waste management and inadequate infrastructure.
Her proposal seeks to combine local community knowledge with geographical information systems and link identified risks to action plans involving municipalities and other stakeholders.
Nawangwe calls for more investment in innovation
Closing the event, Prof. Nawangwe congratulated all the participants and described their presentations as an important beginning for Makerere University, Uganda and the wider region.
Drawing on his experience attending the Falling Walls conference in Berlin, the Vice Chancellor said initiatives of this nature are important because innovation will play a major role in determining the future of countries.
He encouraged participants to make their pitches more precise by clearly identifying the problem they are addressing, explaining their proposed solution and demonstrating what they have already achieved.
Prof. Nawangwe also welcomed the participation of innovators from other universities and countries, noting that the Kampala event had attracted participants beyond Makerere.
He thanked the Africa Office of the Falling Walls Foundation for its role in bringing the initiative to Makerere and encouraged continued support for innovation.
The Vice Chancellor further linked innovation to Uganda’s growing youth population and the need to develop home-grown solutions to address challenges such as youth unemployment.
The inaugural Falling Walls Lab Kampala ultimately provided a platform for innovators to move ideas beyond the classroom and laboratory and demonstrate how research, technology and creativity can be applied to challenges affecting communities.
