Modifiable Co-Morbidities Trends During Hospital Admissions for Obesity in France (2009-2014).

Obesity is a growing public health problem in France, but modifiable co-morbidities in obese patients during their hospital admissions excluding bariatric surgery are lacking. Data were extracted from the French national hospital discharge database. Data on patient admissions, age, gender, and length of stay were extracted by selecting any stay coded primary as obesity. Obesity was defined as body mass index (BMI) between 30-39 kg/m², and morbid obesity as BMI≥40 kg/m². Only modifiable co-morbidities frequently diagnosed during the 6-year period with a rate≥3% were chosen. The admission rate for obesity decreased by 27.2% (P<0.001) with more females than males (71.9% vs. 28.1 %; P<0.001). The main modifiable co-morbidities were hypertension (22.72%), sleep apnea (13.64%), diabetes (12.34%), vitamin D deficiency (7.09%), hyperlipidemia (6.9%), hypercholesterolemia (4.98%), and nonalcoholic steatohepatitis (4.94%). Significant decreases were observed for hypertension (14.5%), diabetes (20%), hypercholesterolemia (30%) with steeper increase for vitamin D deficiency (830.7%) and nonalcoholic steatohepatitis (165.2%). Considering obesity class, admission for obesity (BMI: 30-40 kg/m²) and morbid obesity (BMI≥40 kg/m²) increased (P<0.001) by 6% and 7% respectively. Taking into account severity in proportion, stay>3 days significantly increased by 29.2% (P<0.001). The increase in the proportion of morbid obesity, vitamin D deficiency, and nonalcoholic steatohepatitis adds further evidence on the likely adverse health consequences of modifiable obesity-related comorbidities. There is a need for Health Authorities to promoting healthy lifestyle.
