Participants were selected using simple random sampling. Data collected included demographic information, ankle sprain incidence, history of previous injuries, and leg dominance. Logistic regression and odds ratios (OR) were utilized to analyze relationships between variables.</span></span></span></span></span></span></span></span><br> <span style="font-size:13pt"><span style="text-justify:kashida"><span style="text-kashida:0%"><span style="text-autospace:none"><span style="font-family:&quot;Times New Roman&quot;,serif"><span style="font-style:italic"><span style="font-size:9.0pt"><span style="font-style:normal">&nbsp;&nbsp; <b>Results:</b> The overall incidence of ankle sprains was 43%, with lateral sprains being the most common type. A previous history of ankle injuries was reported by 54% of participants. Basketball players had the highest incidence (58%), followed by volleyball (37.5%) and futsal (33.3%). No significant association was found between sport type and ankle sprain occurrence in either crude or adjusted analyses (crude </span></span><span style="font-size:9.0pt">P</span><span style="font-size:9.0pt"><span style="font-style:normal"> = 0.171; adjusted </span></span><span style="font-size:9.0pt">P</span><span style="font-size:9.0pt"><span style="font-style:normal"> = 0.181&ndash;0.201).
