The binary logistic regression models were used for data analysis. Level of significance was set at  p < 0.05 for all the analysis. Results – The self reported symptoms of short trem insomnia such as  global sleep quality (adjusted odds ratio(AOR)=15.58)  , subjective sleep quality (AOR=6.01), sleep latency (AOR= 5.09) , sleep duration (AOR=0.13), sleep disturbances (AOR=4.88), day time sleep dysfunction (AOR=5.59) had shown association with level of physical activity.
