Association between the Combination of Speed-Eating and Eating until Full and Overweight/Obesity in Part-Time High School Students.

INTRODUCTION: This cross-sectional study aimed to examine the association between overweight/obesity and the combined behavior of speed-eating and eating until full among part-time high school students. METHODS: In 2015, 2,507 male and female part-time high school students from Hyogo Prefecture, Japan, who completed a self-reported questionnaire on lifestyle, were included in the analysis. Overweight/obesity was defined as a body mass index of 25 kg/m2 or more. Responses regarding speed-eating and eating until full were obtained by self-reporting. Logistic regression analysis was used to estimate the odds ratio (OR) for overweight/obesity. RESULTS: Among the participants, 340 (13.6%) were overweight/obese and 468 (18.7%) reported both speed-eating and eating until full. Compared to neither speed-eating nor eating until full group, after adjustment for sex, age, work pattern, physical activity level, sleep duration, frequency of picky eating, frequency of snack intake, fast food intake frequency, frequency of adding salty condiments, frequency of eating less food to save money, and survey schools, the OR (95% CI) for overweight/obesity in speed-eating and not eating until full, eating until full and not speed-eating, and speed-eating and eating until full was 2.11 (1.38-3.22), 1.54 (1.12-2.10), and 2.94 (2.08-4.16), respectively. CONCLUSIONS: The combination of speed-eating and eating until full was associated with overweight/obesity among part-time high school students independent of other lifestyle factors.

Sudden Onset of Platypnea-Orthodeoxia Syndrome Caused by Traumatic Tricuspid Regurgitation With Ruptured Chordae Tendineae After Blunt Chest Trauma.

An 86-year-old man was admitted our hospital because of sudden onset of dyspnea after blunt chest trauma. Because his oxygen saturation deteriorated from 92% in the supine position to 86% in the sitting position, platypnea-orthodeoxia syndrome was suspected. Transesophageal echocardiography showed severe tricuspid regurgitation (TR) caused by anterior papillary muscle rupture. Furthermore, right-to-left shunt with TR through a patent foramen ovale (PFO) was observed. The diagnosis was therefore platypnea-orthodeoxia syndrome with right-to-left shunt through PFO with shunting exacerbated by acute severe TR after blunt chest trauma. The patient underwent urgent tricuspid valve repair and PFO closure and has remained asymptomatic postoperatively.
