Background to the Study: Lower Limb Musculoskeletal Disorders (LLMSDs) have been found to be a common cause of disability. Evidence shows that Physical Activity (PA) reduces symptoms of LLMSDs and has been suggested to be useful in the management of LLMSDs. This study was conducted to investigate habitual PA level and prevalence of LLMSDs in middle aged and older women in Ibadan North Local Government Area of Oyo State, Nigeria. Methodology: This is a cross-sectional survey study in which a non-random sampling technique was used to recruit participants who were mostly workers in Oyo state Secretariat, University College Hospital and University of Ibadan. The International Physical Activity Questionnaire (IPAQ) and the Standardized Nordic Musculoskeletal Questionnaire (SNMQ) were used to evaluate habitual PA level and prevalence of LLMSDs respectively. Descriptive and inferential statistics were used to summarize and analyse the data. Results: Participants were 303 women, age range 45-77 years, mean 53.4±7.6 years. Most 261 (86.1%) were married, had tertiary education 274 (90.4%) and 85 (28.1%) were in the middle income category. Majority 282 (93.1%) reported LLMSDs with the knee (38.6%) being the most frequently reported site. Moderate level of habitual PA were reported by 116 (38.3%) of participants while those with low PA level reported the highest proportion of LLMSDs 118 (41.8%). Conclusion: Middle aged and older women in this study engaged mostly in moderate level of habitual PA, those with low PA had most reports of LLMSDs and the knee was the most frequently reported site of LLMSDs.
