Nutritional Challenges in a Marginalized Workforce: Knowledge, Caloric Intake and BMI Among Tea Garden Workers in Sylhet, Bangladesh

This study evaluated nutritional knowledge, daily caloric intake, and BMI among tea garden workers in Sylhet, Bangladesh. Using a cross-sectional design, face-to-face interviews were conducted with 410 workers (final sample: 390) from January to May 2023. Data included socio-demographics, anthropometric measurements, and dietary assessments. The final sample included 390 participants with a mean age of 35.78 years. Results revealed a mean BMI of 19.64 (SD=3.27), with 39.2% underweight and 7.2% overweight/obese. Nutritional knowledge was poor (79.7%), and mean daily caloric intake (1795.58 kcal) fell significantly below optimal levels. Young adults were less likely to be underweight than older adults. Income level was a significant factor, as workers earning <4000 BDT were more likely to be underweight or overweight. Lack of formal education was associated with a higher likelihood of being overweight, while poor nutritional knowledge was linked to underweight status. Gender and family size also influenced caloric intake, with females and larger families at greater risk of malnutrition. The study underscores the need for targeted interventions addressing education, income, and dietary awareness to improve nutritional health in this marginalized workforce.
