Abstract:
Construction is hazardous for workers' health. This study identifies the prevalence of spinal pain vis-à-vis associated occupational and socioeconomic factors, amongst 600 workers (from 20 construction sites, occupied at 7 work stages). We extracted data from the Nordic-Musculoskeletal-Disorders-Questionnaire and analysed in association with personal and occupational traits, using R-language. All workers were male with ages ranging between 15 and 53 years, a mean value of 28.43, and a mean BMI of 19.89 kg/m2. A total of 506 workers reported pain in the upper back. Odd Ratios (ORs) of work experience were high (6.749) for the upper back. Income and a part-time job with ORs 1.957 and 2.238 affected upper back. The highest OR (1.165) for the upper back was in 'helpers', and for the lower back (1.643) in 'floor/roof slabbers'. The prevalence of pain with frequency (daily) in the upper back is high (n = 197) than the lower back (n = 170). Intervention is suggested to reduce risk factors.
