Abstract

BACKGROUND: Typically, bricklayers in developing countries’ contexts manually lay bricks, concrete blocks and other similar materials to construct walls and buildings which make them susceptible to work-related musculoskeletal disorders (WRMSDs). The burden of WRMSDs among this high-risk group seems has not been well documented. OBJECTIVES: This study examined the prevalence of WRMSDs among bricklayers in Nigeria. METHODS: A cross-sectional survey of 118 consenting bricklayers from a Nigerian setting was carried out. The standardized Nordic musculoskeletal disorder questionnaire and a proforma were used to profile the prevalence of WRMSDs and socio-demographic information of the respondents. Data was analyzed using descriptive and inferential statistics. Alpha level was set at p <  0.05. RESULTS: The 12-months and 7-days prevalence of WRMSDs were 87.3% and 67.4% . Shoulder (61.0%) and the low-back (59.3%) were the two most affected anatomical sites based on 12-month prevalence. WRMSDs affecting the knees (6.8%) was the most disabling in carrying normal work routines. Working for less than 10 years was significantly associated with high prevalence of WRMSDs in the shoulder (odd ratio (OR) = 0.27, 95% confidence interval (CI) = 0.09 to 0.87) and wrist region (OR = 0.24, 95% CI 0.08 to 0.73). Having neck pain led to higher odds (OR = 0.29, 95% CI 0.13 to 0.68) of taking a break from work among the bricklayers. CONCLUSIONS: WRMSDs were high among Nigerian bricklayers. Years of work experience was associated with high prevalence of WRMSDs in the shoulder and wrist. In addition, taking work breaks was associated with neck pain.
