Geospatial Patterns of Cariogenic Feeding Practices Among Children Aged 6-23 Months in Ghana: A Spatial and Multilevel Analysis of the 2022 Ghana Demographic and Health Survey
This study utilizes the 2022 Ghana Demographic and Health Survey to reveal that cariogenic feeding practices among children aged 6–23 months are highly prevalent (52.97%), strongly associated with higher wealth and maternal education, and exhibit significant spatial clustering with high-risk areas concentrated along the southern coastal belt.

In the first two years of life, a child's mouth is a construction site. Tiny teeth are erupting, and the habits formed during this window set the stage for dental health for decades to come. One of the most significant threats to these young teeth is not a lack of hygiene, but the food and drink they consume. When sugary liquids or sticky snacks sit against teeth for long periods, bacteria in the mouth feast on the sugar and produce acid. This acid eats away at the tooth enamel, leading to cavities, a condition known as early childhood caries. While this disease is common worldwide, it is often overlooked in low-income countries where access to dentists is scarce. The challenge for public health officials is not just knowing that these cavities exist, but understanding exactly where they are happening and why. Without a clear map of the problem, resources meant to prevent tooth decay might be sent to the wrong places, leaving the children who need help the most without support.
Researchers in Ghana recently set out to draw this missing map. They turned to a massive national survey that had already collected detailed information from thousands of households across the country. Instead of just counting how many children had sugary habits, the team looked at the geography of those habits. They focused on children between six and twenty-three months old, a critical period when families introduce solid foods and new drinks. The researchers created a simple measure to identify "cariogenic feeding," which simply means feeding practices that are likely to cause cavities. This included giving a child a bottle with a sweetened liquid, offering sugary sodas or juices, or feeding them processed snacks like candy, cookies, or cakes. If a child experienced any one of these, they were counted as being exposed to the risk.
The team analyzed data from 3,007 children, linking each child's household to a specific location on a map. They wanted to see if these risky feeding habits were scattered randomly across the country or if they clumped together in certain areas. The results revealed a stark reality: nearly 53% of all children in this age group in Ghana are exposed to cariogenic feeding. However, this risk is not spread evenly. The data showed a clear divide between the north and the south of the country. In the northern regions, such as Savannah and Northern, the prevalence of these habits was relatively low, affecting fewer than 30% of children. In contrast, the southern coastal regions told a different story. In the Western Region, for example, more than 73% of children were exposed to these sugary foods and drinks.
What makes this finding particularly surprising is the link to wealth and education. Usually, in public health, the poorest families face the highest risks of disease. Here, the pattern was reversed. Children from the wealthiest households were far more likely to be fed cariogenic foods than those from the poorest families. The study found that children in the richest homes had roughly four times the odds of exposure compared to children in the poorest homes. Similarly, children whose mothers had higher levels of education had roughly two and a half times the odds of being fed these foods compared to children whose mothers had no formal education. This suggests that in Ghana, feeding a child sweetened beverages or processed snacks is often seen as a sign of modernity or affluence, rather than a sign of poverty. The researchers also found that living in a city was not the main driver of this risk once wealth and education were taken into account; rather, it was the resources and education of the household that mattered most.
Using advanced mapping techniques, the researchers identified specific "hot spots" where these risky habits were concentrated. These clusters were not random; they formed a distinct band along the southern coast, stretching through the Greater Accra region, the Volta region, and into the Ashanti region around the city of Kumasi. In these areas, entire neighborhoods showed high rates of cariogenic feeding, surrounded by other neighborhoods with similar habits. Conversely, a broad "cold spot" of low risk covered the northern half of the country. This spatial pattern means that a national average number hides the true severity of the problem in specific communities. If health officials only looked at regional averages, they might miss the intense pockets of risk in the south or the relative safety of the north.
The study concludes that to protect children's teeth, health campaigns cannot rely on a one-size-fits-all approach. The children who need the most help are not necessarily the poorest, but rather those in wealthier, more educated households in the southern parts of Ghana. Public health workers should prioritize these specific high-risk areas, using existing platforms like growth monitoring and immunization clinics to teach caregivers that sweetened drinks and processed snacks are not the best choices for their infants. By targeting these specific geographic and socioeconomic groups, Ghana can move beyond guessing where the problem lies and start delivering prevention exactly where it is needed most.
