Prevalence of low back pain among peasant farmers in a rural community in South South Nigeria.

INTRODUCTION This study was undertaken to assess the prevalence and predominant causes of low back pain (LBP) among peasant farmers in Ebubu community in South-south Nigeria. METHODS This was a community based cross-sectional study of 310 consenting, adult, full-time farmers, recruited using a two-stage cluster sampling scheme developed by WHO. Specially trained community health extension workers interviewed participants using a pre-tested questionnaire designed by the authors to solicit information on defined LBP. Socio-demographic characteristics were also obtained. A clinical history was recorded, including: duration of LBP and mode of onset, pain severity, knowledge of LBP causes and care-seeking practices. Participants' BMI were calculated. Data were entered into Microsoft Excel and analyzed using the Statistical Package for Social Sciences v15 (www.spss.com). RESULTS Of the 310 apparently healthy farmers (age range 18-58 years [mean 36.71±8.98]; 132 males) sampled, 208 had LBP (67.10%). Low back pain was more prevalent in the 31-40 years age group (49.04%), females (50.96%), those who were non-obese (68.95%) or tall (73.2%) and those who had practiced farming for a long duration. Severe LBP was significantly (p<0.05) linked to aging (51-60 years group), low BMI and those above average height (1.60 m). CONCLUSION This study indicates that LBP is a prevalent health problem among rural peasant farmers. It was more prevalent in the middle-aged groups, and among females, the non-obese and tall individuals, and those who had been farming for a long duration. Severe LBP was linked to aging, high BMI and those above average height.
