Participants self-reported winter weight change, time needed to return to their usual pre-winter weight, diet, physical activity, sedentary time, alcohol use, and sleep. Sex-stratified binary logistic regression identified predictors of winter weight gain and prolonged weight retention (\u22641 month vs. &gt;1 month).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Winter weight gain was reported by 51.1% of men and 68.2% of women; the mean (standard deviation) increases were 2.3\u2009\u00b1\u20091.2 and 2.0\u2009\u00b1\u20091.1\u2005kg, respectively. Among participants who reported winter weight gain, 61.8% indicated that their weight returned to normal within 1 month, whereas 38.2% required more than 1 month. In men, prolonged retention was predicted only by longer sedentary time during holidays. In women, predictors of prolonged retention included more frequent alcohol consumption and shorter sleep; winter weight gain itself was associated with lower intake of instant\/retort foods, less weekday sitting, and more frequent exercise.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Winter weight gain is common among Japanese university students, particularly women, with sex-specific predictors of persistence.
