A small study of 86 pregnant women in Bangladesh tea gardens revealed a 12.7% prevalence of gestational diabetes mellitus (GDM), alongside concerning rates of underweight (28%) and pregnancy complications (16.5%). The women averaged 23 years of age with mean pregnancy duration of 18.8 weeks, and nearly half were first-time mothers. These findings illuminate health disparities in Bangladesh's tea industry communities, where workers face unique occupational and socioeconomic challenges. The GDM rate aligns with global trends showing rising diabetes prevalence, but the high underweight percentage contrasts with typical obesity-diabetes associations, suggesting malnutrition may be a contributing factor. This research addresses a critical knowledge gap, as tea garden workers represent a vulnerable population often excluded from mainstream health surveillance. However, the extremely small sample size and purposive sampling limit generalizability, while the cross-sectional design prevents causal inferences. As this is a preprint awaiting peer review, these preliminary findings require validation through larger, more rigorous studies before informing public health policy for this underserved community.
