The final analytic sample included 21,599 adults aged ≥19 years. We identified weight change over the past year and categorized it into seven groups (≥10 kg loss, 6–<10 kg loss, 3–<6 kg loss, no weight change, 3–<6 kg gain, 6–<10 kg gain, and ≥10 kg gain). We analyzed the odds of depressive symptoms, self-reported physician diagnosis of depression, and perceived stress according to the change in weight.</p>Results<p>Higher odds of depressive symptoms, self-reported physician diagnosis of depression, and perceived stress were observed at both substantial weight loss and weight gain.
