Competitors (<i>N</i> = 256) from CS including boxing, Brazilian jiu-jitsu, muay thai/kickboxing (MT/KB), wrestling, mixed martial arts (MMA), judo, taekwondo, and karate participated in the study. Athletes completed an online survey which included questions on their regular weight loss habits, including magnitudes of weight loss over different time periods and types of methods utilised. Athletes typically started losing weight in their early 20s and engaged in RWL on average three times a year. Magnitudes of weight loss were greater in MT/KB and MMA than other cCS examined (<i>d</i> between 0.63 and 1.54). Wrestlers demonstrated higher prevalence of skipping meals or fasting than other CS (<i>d</i> between 0.7 and 1.29). Athletes at higher competitive levels engaged in larger magnitudes of RWL (<i>d</i> between 0.49 and 0.57). The usage of methods of body fluid manipulation such as fluid restriction, water loading, and sauna were associated with greater amounts of weight loss within 2 weeks and 24 h of weighing in (<i>d</i> between 0.36 and 0.45). Findings indicate that larger weight cuts are linked to strategies involving higher risk, such as sauna, and may be more common among athletes who begin RWL practices at a younger age. Use of certain high-risk methods were associated with increased likelihood of disordered eating behaviours. To reduce reliance on these practices, practitioners and regulators should emphasise the use of smaller weight cuts and to begin losing weight further out from competition.</p>","PeriodicalId":75247,"journal":{"name":"Translational sports medicine","volume":"2025 ","pages":"2946317"},"PeriodicalIF":1.2,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11964705/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143774945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whilst student athletes (St-A) are often perceived as having healthier lifestyles compared to nonathlete students (NAS), it is unclear whether they exhibit better risk profiles. This study compares the prevalence and clustering of these lifestyle-related risk behaviours among NAS and St-A at a South African university. <b>Methods:</b> This cross-sectional study assessed the prevalence of alcohol consumption, cigarette smoking, inadequate fruit and vegetable intake and physical inactivity using a screening questionnaire. Differences between gender and athletic status were analysed using chi-square tests. Cluster analysis was employed to identify patterns of co-occurring risk behaviours within the combined cohort. <b>Results:</b> One hundred and forty-five St-A (<i>n</i> = 91 male, <i>n</i> = 54 female) and 143 NAS (<i>n</i> = 90 male, <i>n</i> = 53 female) were included. Similar alcohol use patterns were observed between St-A and NAS (<i>p</i>=0.737), but females consumed less alcohol than men (<i>p</i>=0.025). Smoking was less prevalent among St-A (18.6% vs. 32.2% NAS, <i>p</i>=0.020). Less than 10% of participants met fruit and vegetable intake recommendations, with females consuming more than males (<i>p</i>=0.002). St-A met the moderate activity guidelines more often (73.0% vs. 44.3%, <i>p</i> < 0.001) and the vigorous physical activity guidelines more often (71.5% vs. 37.1%, <i>p</i> < 0.001) than NAS. The cluster analysis identified a higher risk group (34.6% St-A) with multiple risk behaviours, and a healthier group (all meeting vigorous activity goals and none smoking). <b>Conclusions:</b> Both St-A and NAS engage in lifestyle-related risk behaviours. Further investigation into the interconnections of these behaviours and the implementation of university-based interventions is warranted.</p>","PeriodicalId":75247,"journal":{"name":"Translational sports medicine","volume":"2025 ","pages":"1994649"},"PeriodicalIF":1.2,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11949602/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143733535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
