Assessment of Trend, Pattern and Predictive Factors Determining Infant Mortality Among the Tea Garden Labour Community of Assam, India

In many parts of the world, the number of babies who do not survive their first year serves as a stark measure of a community's overall health and well-being. This figure, known as the infant mortality rate, acts like a sensitive barometer, reflecting everything from the quality of medical care available to pregnant women and newborns to the cleanliness of the water people drink and the food they eat. When this rate is high, it often signals that a community is struggling with deep-seated issues related to poverty, education, and access to basic services. While national statistics can show broad trends, they often hide the specific struggles of smaller, marginalized groups who live in distinct conditions. Understanding the precise reasons why infants die in these specific pockets of society is essential for designing help that actually works, rather than guessing what might be needed.

In the lush, rolling hills of Assam, India, a vast network of tea plantations supports a unique community of laborers whose lives have been shaped by generations of work in the gardens. Despite the economic importance of the tea industry, the families living within these estates often face significant hardships, including overcrowded housing and limited access to modern amenities. Researchers Anindita Chakravarty and Nayanmoni Borgohain Baruah from Dibrugarh University set out to understand the specific health challenges facing the infants in this community. They wanted to move beyond general assumptions and gather hard evidence about how many babies were dying, what was causing these deaths, and which factors in the parents' lives made the difference between life and death.

To get a clear picture, the team traveled to five major tea-growing districts in Assam: Dibrugarh, Tinsukia, Sivasagar, Jorhat, and Sonitpur. They did not rely on old records or guesses; instead, they went directly into the field to speak with families. Using a careful sampling method, they selected 1,308 households from across these districts. From each home, they interviewed a woman between the ages of 15 and 49, focusing specifically on those who had given birth in the five years leading up to the study. This approach allowed the researchers to gather fresh, detailed stories about the health of mothers and their children, covering everything from the mother's education and income to the type of toilet the family used and whether she received medical checkups during pregnancy.

The results of this fieldwork revealed a sobering reality. During the five-year period from 2019 to 2023, the researchers recorded 2,233 live births among the families they surveyed. Unfortunately, 74 of these infants did not survive their first year. This translates to an infant mortality rate of roughly 33 deaths for every 1,000 babies born. While this number is lower than rates recorded in similar communities in the past, it remains higher than the national average for India. The data also showed that the year 2021 saw the highest number of deaths, a spike the researchers linked to the indirect effects of the global pandemic, which disrupted healthcare access and caused many pregnant women to miss crucial checkups.

When the researchers looked at the causes of these tragic losses, a clear pattern emerged. The most common reasons for death were respiratory disorders, followed closely by babies born too early or with low birth weight. Viral fevers, diarrhea, and jaundice were also significant contributors. A troubling finding was that for nearly 19 percent of the deaths, the specific cause could not be identified or diagnosed, suggesting that many families lack access to the medical facilities needed to understand what is happening to their sick children. These causes point to a mix of biological vulnerabilities and environmental dangers, where unhygienic living conditions and a lack of clean water make infants particularly susceptible to illness.

To understand what could be done to change these numbers, the team analyzed the data to see which factors were truly driving the risk of infant death. They found that three specific elements stood out as the most powerful influences. First, the education level of the mother played a critical role; as a mother's years of schooling increased, the likelihood of her infant dying dropped significantly. Educated mothers appeared better equipped to make decisions about hygiene, nutrition, and when to seek medical help. Second, whether a baby was born prematurely was a major factor, with babies born too early facing a much higher risk of death than those born at full term. Third, the use of antenatal care—medical checkups a mother receives while pregnant—was vital. Mothers who did not receive these checkups were far more likely to lose their infants, highlighting the life-saving importance of regular medical supervision during pregnancy.

The study also examined other common assumptions about what drives infant mortality, such as the family's monthly income, the age of the mother, or the order in which the child was born. Surprisingly, the data showed that these factors did not have a statistically significant impact on whether an infant survived in this specific community. While income is often thought to be the primary driver of health outcomes, the researchers found that in the tea garden context, education and medical care mattered more. Similarly, while the sex of the child and the availability of a proper toilet facility did show some influence, their effects were less pronounced than the impact of education and prenatal care. The presence of a toilet, for instance, reduced the risk of death, but it was not as decisive as ensuring the mother was educated and received medical attention.

These findings offer a clear path forward for improving the health of this community. The research suggests that simply providing more money to families may not be the most effective solution if the underlying issues of education and healthcare access are not addressed. Instead, targeted efforts to keep mothers in school, ensure they receive regular checkups during pregnancy, and prevent premature births could have the greatest impact. By focusing on these specific, proven factors, policymakers and health workers can design interventions that directly address the root causes of infant mortality in Assam's tea gardens, potentially saving lives and building a healthier future for the next generation of tea workers.
