Socioeconomic, Lifestyle, and Dietary Factors Associated with Concurrent Hypertension and Diabetes among Adults in Selected Communities in Southwestern Nigeria: A Cross- Sectional Study
This cross-sectional study in Southwestern Nigeria found that 14.8% of adults with hypertension or diabetes had both conditions, with higher income showing a consistent but statistically non-significant positive association after multiple-testing correction, highlighting the need for integrated screening and further confirmatory research.

In many parts of the world, two silent health conditions often travel together: high blood pressure and diabetes. High blood pressure is a state where the force of blood against the walls of the arteries is consistently too strong, straining the heart and vessels. Diabetes occurs when the body struggles to manage sugar in the blood, leading to levels that are dangerously high. When these two conditions appear in the same person, the risk of serious complications like heart disease, kidney failure, and early death rises sharply, far beyond the risk posed by either condition alone. This combination is becoming a growing concern in Nigeria, where health systems are already stretched thin. Understanding why some people develop both conditions while others do not is critical, especially as researchers look at how daily life, money, and food choices might influence this dangerous pairing.
A team of researchers set out to investigate this exact question in the southwestern region of Nigeria. They wanted to know how common it is for adults to have both high blood pressure and diabetes at the same time, and what factors in their lives might be linked to this double burden. To find the answer, they did not simply ask people who already knew they were sick to join a study. Instead, they went into several urban and peri-urban communities and randomly selected 500 adults to undergo a health check. This approach ensured they captured a true picture of the community, rather than just those who had already sought medical help. During these visits, the team measured blood pressure and checked blood sugar levels. They found that nearly half of the people they screened showed signs of at least one of these conditions. Among those who screened positive, the researchers then conducted a much deeper investigation, asking detailed questions about their income, daily habits, and what they ate.
The study revealed that among the adults who had at least one condition, about 15 percent were living with both high blood pressure and diabetes simultaneously. This is a significant portion of the population, representing a heavy load on the community's health. When the researchers looked for the causes, they examined everything from smoking and alcohol use to how often people exercised and skipped meals. They also analyzed dietary patterns, grouping foods into broad categories like a "plant-rich traditional" diet or a "grain and snack" diet. Surprisingly, none of these specific lifestyle habits or food patterns showed a clear, independent link to having both diseases after the researchers accounted for the many different factors they tested. The data did not support the idea that skipping meals, adding salt to food, or following a specific diet was the primary driver for this double diagnosis in this group.
The most noticeable pattern that emerged was related to money, though the researchers were careful about how they presented this finding. People with higher monthly incomes were more likely to have both conditions compared to those with lower incomes. This might seem counterintuitive, as one might assume that having more money leads to better health. However, the researchers explained that higher income can sometimes mean better access to healthcare, which leads to more frequent detection of these conditions. It can also be associated with sedentary jobs and access to energy-dense foods that contribute to the problem. Despite this consistent trend appearing in their analysis, the researchers noted that when they applied a strict statistical check to ensure the result was not a fluke caused by testing so many different variables, the link did not hold up as definitively proven. Therefore, while the income connection is a strong signal worth watching, it remains a suggestion rather than a confirmed rule.
Ultimately, this study highlights that the coexistence of high blood pressure and diabetes is a real and pressing issue in these Nigerian communities, affecting a meaningful number of adults. The findings suggest that this health burden is not limited to the poorest members of society, challenging the assumption that only those with fewer resources suffer from such chronic diseases. Because the study was a snapshot in time and relied on single visits for testing, it cannot prove what causes what. The researchers conclude that the best path forward is to screen for both conditions together in the community and to conduct larger, long-term studies that can track people over time. Only through such careful, continued observation can the true reasons behind this dual health crisis be understood and addressed.
