INTRODUCTION

Sanitation workers do physically demanding job like collecting, segregating, and disposing waste. They are prone to develop musculoskeletal problems. The study aimed to measure sociodemographic profile and musculoskeletal morbidity among sanitation workers employed by the Thiruvananthapuram corporation.

OBJECTIVES

To estimate the prevalence of musculoskeletal pain among, sanitation workers employed by Thiruvananthapuram corporation and factors associated with it.

METHODOLOGY

A cross-sectional study was conducted in Thiruvananthapuram corporation. The designated sanitation workers employed by Thiruvananthapuram corporation were study population. 165 workers sampled out of 641 workers, working for not less than 12 months from before initiation of study, were included in study and were selected by simple random sampling.
