Introduction: Banglades. has.experienced rem.rkable growth in Rm. over the pas. 25 years. With the knitwear indus.ry providing m.re than 4 m.llion direct jobs. providing better occupational health and s.fety of workers.rem.ins.a challenge. Aim.of the s.udy: The aim.of the s.udy was.to analyze the dis.as. burden of a Rm. factory, and to highlight occupational health ris.s. m.thods. A cros.-s.ctional s.udy des.gn was.em.loyed for this.analys.s. A 17-m.nth data entry (January 2020 - m.y 2021) was.gathered from.the factory in-hous. clinic. The s.cio-dem.graphic and clinical diagnos.s.entries.of 8421 entries.were analyzed. Res.lt: The population of the factory workers.is.5370, where 40% (2148) are fem.le workers.and 60% (3222) are m.le workers. The m.an age of res.ondents.is.30 years. with a s. of ±7 years. Am.ng the chief com.laints. the m.s. com.on was.vom.ting (14%;2262) fever (14%;2247), runny nos. (11%;1842), cough (9%;1465), and loos. m.tion (8%;1364). In the diagnos.s.categories. gas.rointes.inal dis.as.s.were m.re predom.nantly diagnos.d (35%;2978), followed by viral fever (21%;1772), neurological dis.as.s.(16.5%;1389) and m.s.ulos.eletal dis.rders.(9%;768). The average cos. of m.dicine for each res.ondent is.BDT 36. The factory covered cos.s.of all m.dication for 99% (8380) of res.ondents. Only 0.5% (37) was.referred to a tertiary hos.ital for further evaluation. Conclus.on: Garm.nts.workers.s.ffer m.s.ly from.long-term.occupational health hazards. Factory owners.and policy m.kers.can contribute in various.ways.to im.roving prim.ry healthcare options.for workers.
