Background: Call-center operators are exposed to working conditions that indicate an increased risk of developing musculoskeletal disorders. Nevertheless, there are few studies regarding health and working condition in call-center operators. Thus, this study was designed to investigate the physical activity levels and prevalence of low back pain (LBP) in Thai call-center operators. Materials and Methods: A self-reported questionnaire was distributed to 150 operators at a call center to identify the physical activity levels, prevalence of LBP, personal characteristics, and associated work factors. Results: The questionnaire response rate was 70% (n = 105). The participants' age was 27.8 ± 3.1 years, height was 159.97 ± 6.26 cm, weight was 52.89 ± 12.89 kg, and females 86.7% (n = 91), and males 13.3% (n = 14). Participants worked at least 6 days every week, with an average of 8 hours each day. Sixty-one percent of them worked over time with an average 2 h/day. Forty percent of the participants had no exercise; 34.3% exercised 1–2 times/week. Those who did physical exercise spent less than 30 min/time. The overall self-reported prevalence of LBP was 65.7%, and they reported high severity of LBP for 42.9%. All participants reported that their LBP as recurring, and 62.9% reported that LBP was aggravating by sitting during working hours. Conclusion: The call-center operators had a sedentary work style. The majority of operators in this study had low level of physical activity and suffered from low back pain. The prevalence of low back pain was associated to their level of physical activity and work factors.
