Twelve-month suicidal ideation in Bangladesh after the first pandemic year: an updated systematic review and random-effects meta-analysis
This updated systematic review and meta-analysis of 12 cross-sectional studies involving nearly 10,000 participants reveals a pooled 12-month suicidal ideation prevalence of 13.2% in post-pandemic Bangladesh, though extreme heterogeneity among the studies precludes definitive national or temporal conclusions and underscores the urgent need for standardized, repeated surveillance.

In many parts of the world, counting how many people die by suicide is a difficult task. Records are often incomplete, and the reasons behind these tragedies are complex and deeply personal. In Bangladesh, this challenge is even more pronounced, with data that is fragmented and hard to compare. When the global pandemic arrived, bringing economic hardship, isolation, and fear, mental health experts worried that the pressure on the population would lead to a rise in thoughts of ending one's life. To understand the scale of this distress, researchers look for "suicidal ideation," a term that simply means a person having thoughts about suicide, even if they never act on them. While a single survey can offer a snapshot of a specific group, it cannot tell the whole story of a nation. To get a clearer picture, scientists often combine the results of many different studies, looking for patterns that emerge when the data is viewed together. This approach helps separate the noise of individual studies from the broader reality of a population's mental state.
A recent study by Md. Al Mamunur Rashid from Noakhali Science and Technology University takes this approach to examine the mental health landscape in Bangladesh after the first year of the pandemic. The researcher gathered twelve separate studies that were conducted between 2021 and 2024, involving nearly ten thousand people from various backgrounds, including students, rural adults, and people with disabilities. These studies were chosen carefully to ensure they asked about thoughts of suicide within the last twelve months, rather than just asking if someone had ever felt this way in their entire life. By bringing these twelve pieces of evidence together, the researcher aimed to find a single, reliable number that could represent the frequency of these thoughts across the country during this turbulent time.
The analysis revealed that, across these specific groups, about thirteen out of every hundred people reported having thoughts of suicide in the past year. However, the most important finding of the study is not this specific number, but the wide variation between the different groups surveyed. When the researcher looked at the data, the results did not cluster tightly around a single average. Instead, the estimates ranged wildly, from as low as four percent in some groups to as high as thirty-six percent in others. This extreme difference means that the thirteen percent figure cannot be treated as a national average for all of Bangladesh. It is more like a collection of different snapshots, each showing a different scene depending on who was asked and how they were asked.
The study also looked at whether the type of person surveyed made a difference. The researcher compared groups of students and those connected to education with groups of general community members and people with disabilities. While the students showed a slightly higher rate of these thoughts, the difference was not large enough to be considered a definitive rule. Similarly, the year the data was collected—whether in 2021, 2022, or 2024—did not show a clear pattern of increase or decrease over time. The variation was so great that the researcher could not say with certainty that the problem was getting better or worse from year to year. Even when the researcher focused only on the four studies that were conducted with the highest level of scientific rigor, the estimated rate dropped to about seven percent, yet the uncertainty remained high.
This wide spread in the numbers tells a crucial story about the state of knowledge in Bangladesh. The researcher concludes that we currently do not have a single, reliable way to measure how common these thoughts are across the entire country. The studies that exist were often small, used different ways of asking questions, and did not always represent the whole population. Some studies relied on people who volunteered to answer online, while others used more structured methods to reach people in rural villages. Because the methods were so different, the results cannot be easily compared to one another. The researcher notes that without a consistent, national system for tracking these thoughts using the same questions every time, it is impossible to know the true scale of the issue or to see if it is changing over time.
The study suggests that the current data is not enough to guide national policy or to claim that the country has a specific prevalence rate. Instead, it highlights a need for better surveillance. The researcher calls for repeated surveys that use the same trusted questions and include a representative mix of people from all over the country, not just students or those who are easily reached online. Until such a system is in place, the numbers we have will remain a collection of isolated glimpses rather than a clear map of the mental health landscape. The work serves as a reminder that while we know distress is present, understanding its full scope requires a more careful and consistent approach to counting and listening.
