I googled it and here is what I came up with

Using a sample of 414 NCAA Division-I female collegiate athletes, we examined the relations of required team weigh-ins or self-weighing on disordered eating attitudes and behaviors.
Through a series of multivariate analyses, we determined that team weighs were unrelated significantly to all outcome measures.
I downloaded the article and read the entire article (rather than just the abstract). One issue I have with the study is that participants were not asked how often the team weigh-ins were. Were they daily? Weekly?
Weigh-in Status. We determined the status of team weigh-ins through the question, “Does your team conduct regular ‘weigh-ins’ (i.e., YES or NO).” We assessed the status of self-weighing through the question “On average, how many times do you weigh yourself per week?”
(Athletes provided a number).
This is what the article had to say about the frequency of weighing:
Self-weighing, particularly 3 or more times per
week, was related to more dietary restraint and higher
levels of bulimic symptoms. Restricting caloric intake
and purging (e.g., excessive exercising, vomiting) are
behavioral means through which athletes may try to
lose weight and bring their bodies closer to their desired
weight. Self-weighing provides immediate verification of
success or failure, and orients female athletes toward their
bodies and reminds them of their actual weight. The more
constant the reminder that their weight is discrepant from
their ideal, the stronger their motivation to calorically
restrict or purge in hopes of eventually changing the numbers
on the scale. Regardless of the weight outcome, the
athletes’ self-weighing behaviors are reinforced because
the scale provides them with self-evaluative information.
Were the team weigh-ins more or less often than three times a week? The study does not specify. Since they seem critical of athletes who self-weigh more than three times a week, it might be possible that the team weigh ins were less often than that. It seems that's a pretty important variable that they neglected to collect.
“Mandatory team-conducted weigh-ins appear to not be a salient pressure for female gymnasts and swimmer/divers, although the frequency of their self-weighing may represent a level of self-monitoring that is associated with greater endorsement of disordered eating attitudes and behaviors.”
just because something has resulted /can induce eating disorders does not mean it is. This study did not find a definitive link? What studies have found a definitive link?
