Ageing, Chronic Disease Burden, and Household Health Expenditure in Bangladesh: Evidence from HIES 2022
Using 2022 HIES data from 14,395 Bangladeshi households, this study finds that while ageing is descriptively linked to higher spending, the burden of chronic disease is the most consistent and statistically significant predictor of household health expenditure, underscoring the need for financial protection against chronic care costs.

In many parts of the world, paying for medical care is a shared responsibility between families and the government. But in places like Bangladesh, the cost of a doctor's visit, a medicine, or a hospital stay often falls directly on the family's shoulders. This reality creates a difficult question for policymakers and families alike: what actually drives these costs? Is it simply the fact that a family has older members who naturally need more care as they age? Or is it the presence of long-term illnesses that require constant attention, such as diabetes or heart disease? Understanding the difference matters because it changes how a country should protect its people. If costs are driven mostly by age, support might focus on pensions or general senior care. If costs are driven by chronic sickness, the solution might lie in making long-term medicines and regular check-ups affordable for everyone.
A recent study by researchers at Shahjalal University of Science and Technology looked closely at this question using the most recent national data available. They examined nearly 14,400 households across Bangladesh to see how the mix of people living in a home—specifically the number of older adults and the number of people with long-term illnesses—relates to the money the family spends on health each month. The researchers did not just ask people how much they spent; they carefully reconstructed the data from a massive national survey called the Household Income and Expenditure Survey, ensuring their numbers matched official government records. This allowed them to see the full picture of what families are actually paying for, from daily medicines to hospital stays, and to separate the influence of age from the influence of chronic disease.
The researchers found that while having older family members is a factor, it is not the strongest driver of health spending when other details are taken into account. The most consistent and powerful predictor of how much a family spends on health is the share of household members living with a chronic illness or disability. In the data, families where a larger portion of members had long-term health conditions spent significantly more money on health every month. The study calculated that for every small increase in the proportion of family members with chronic conditions, the monthly health bill rose noticeably. This held true even after the researchers adjusted for how much money the family earned, how many people lived there, where they lived, and how educated the head of the household was.
In contrast, the presence of older family members alone told a different story. When the researchers looked at the raw numbers, families with older members did tend to spend more. However, once they accounted for the fact that older members often also have chronic illnesses, the direct link between age and spending became much weaker and statistically uncertain. This suggests that the extra cost associated with aging is largely because older people are more likely to have long-term health problems that require repeated care, rather than age itself being the sole cause of high bills. The data showed that households containing both older members and those with chronic illnesses faced the highest costs, spending an average of 3,240 Bangladeshi Taka per month. This was significantly higher than households with only chronic illness (2,232 Taka) and far higher than those with only older members (966 Taka).
The study also highlighted that where a family lives and how much they earn plays a major role. Families in cities spent more on average than those in rural areas, and wealthier families spent more than poorer ones. The researchers noted that this does not necessarily mean wealthier families are sicker. Instead, it likely reflects that families with more money can afford to seek care, buy medicines, and use diagnostic tests, while poorer families might spend less because they cannot afford to get the care they need. This distinction is crucial: lower spending in poorer households might not mean lower health needs, but rather unmet needs and delayed treatment.
Ultimately, the research points to a clear conclusion for how health support should be designed in Bangladesh. Because the burden of chronic disease is the most reliable signal of high household spending, financial protection systems should prioritize helping families manage these recurring costs. This means focusing on making medicines, routine check-ups, and follow-up care affordable for those with long-term conditions. While aging remains a relevant factor, the study suggests that policies should not treat age and chronic illness as separate issues. Instead, they should recognize that the financial pressure on families often comes from the overlap of these two realities, and that the most effective way to protect households is to address the steady, repetitive costs of long-term sickness.
