Background: Obesity is associated with a paradoxical nutritional imbalance, where excessive energy intake often coexists with deficiencies in essential micronutrients. This imbalance contributes to an increased risk of various comorbidities and mortality in obese patients. The aim of our study was to assess the nutritional status in a population of obese adult patients.
Methods: This is a descriptive, cross-sectional observational study involving 100 obese adult patients. Body composition was assessed using a SECA MBCA 515 bioelectrical impedance analysis. Dietary data were analyzed using Nutrilog software. The diagnosis of sarcopenic obesity (SO) was established according to the latest consensus proposed by ESPEN and EASO [1].
Results: The mean age was 44.42±13.25 years with a sex ratio (M/F) of 0.11. The mean BMI was 40.07±5.77 kg/m², with morbid obesity identified in 48% of the patients. The mean arm muscle circumference was 32.31±3.01 cm and 26.06±3.34 cm, respectively in male and female patients with 82% of patients exhibiting normal values. The mean skeletal muscle mass and appendicular skeletal muscle mass were 26.83±6.63 kg and 16.07±4.06 kg, respectively. A decrease in fat-free mass index was noted in 20% of patients. The average muscle strength was 39.14±11.79 kg in male patients and 23.40±5.79 kg in female patients with muscle strength impairment observed in 21% of the patients. SO was diagnosed in 19% of the study population. Biological nutritional assessment revealed anemia in 18% of patients, hypophosphatemia in 4% of patients, 25(OH) vitamin D insufficiency was found in 37% and deficiency in 62% of patients. The mean albumin level was 41.91±2.31 g/l, with normal albumin and calcium levels in all patients. Dietary survey data analysis revealed a hypercaloric intake in the majority of patients (75%), a high carbohydrate intake in 48%, a high lipid intake in 93%, and a low protein intake in 9% of patients. The majority of the study population had insufficient intake of EPA (95%) and DHA (96%). Micronutrient deficiencies were mainly marked by deficiencies in vitamin A (90%), vitamin D (88%), calcium (55%), vitamin B9 (44%), and vitamin C (32%).
Conclusion: The results of our study highlight the critical need for a comprehensive nutritional assessment in obese patients to detect malnutrition or associated nutritional deficiencies, and to optimize their management.
