Given the global decline in adherence to the Mediterranean Diet (MD), even within its native region, it is key to identify the factors influencing this trend to mitigate the negative health outcomes associated with westernized diets. To this end, 4025 individuals (49.6% women, 42.6 ± 14.2 y/o) from Greece, Italy, Morocco, Slovenia, and Tunisia remo...

Background: Obesity is a chronic disease associated with numerous complications, including metabolic syndrome, type 2 diabetes, and cardiovascular diseases. Adipose tissue functions as an endocrine organ, producing hormones that play a crucial role in regulating metabolic homeostasis, such as ghrelin and resistin. Objective: The aim of this study w...

The literature is prolific in studies about the artificial intelligence (AI) applications, particularly to support formal education and develop adaptive lifelong learning environments by means of an array of flexible, inclusive, and interactive tools. AI-based education is assumed to be determinant for the achievement of the Sustainable Development...

Background: Obestatin and ghrelin are two gastric hormones that have a potential role in dietary intake regulation. Obestatin/ghrelin ratio has been proposed as activity markers in obesity. The study aimed to evaluate ghrelin, obestatin and the ghrelin/obestatin ratio in obese compared to control subjects and to determine their relationship with an...

Introduction: The objectives of our work were to compare the serum concentrations of lipid parameters,insulin, resistin, ghrelin, zinc and magnesium between two groups of men with obese type 2 diabetes and a control group and to study possible correlations between these differentparameters. Material and methods: This was a monocentric case-control...

Background Diabetes, a major public health issue in Tunisia, is responsible of an increased burden of morbidity and premature mortality. Achieving a good glycemic control is essential for reducing the morbidity-mortality associated with this disease. The purpose of our study was to assess the proportion of uncontrolled diabetes (UD) among Tunisian...

Background Diabetes management requires access to health care, patient awareness about hygiene and diet measures, and patient adherence to prescribed treatment. Health care renunciation (HCR) can make diabetes management really challenging. We aimed to determine the prevalence of HCR in diabetic Tunisian patients and assess associated factors. Met...

Background Hypertension is becoming increasingly frequent mainly in low and middle income countries. We aimed to assess the prevalence, awareness and control of hypertension among Tunisian adults and identify associated factors with hypertension control. Methods Data were obtained from the 2016 Tunisian Health Examination Survey, a household surve...

Background: Physical activity (PA) is an important agent in the prevention of chronic diseases such as obesity. Objectives: To provide preliminary data on PA among school children and to correlate the PA with weight status. Material and methods: A total of 40 children aged between 8 and 11 years and attending Tunisian schools were recruited. T...

Background/objectives: Accuracy of impedance analysis depends on population-specific prediction equations. The aim of this study was to propose new prediction equations to estimate body composition using impedance analysis for healthy Tunisian children and validate them using the deuterium oxide dilution (D2O) technique. Subjects/methods: Body c...

Metabolic syndrome is a serious consequence of obesity characterized by increased cardiovascular risk factors such as hypertension, dyslipidemia, and glucose intolerance. While diets enriched with natural antioxidants showed beneficial effects on oxidative stress, blood pressure, and serum lipid composition, diet supplementation with synthetic anti...

Background Diabetes mellitus is one of the most common endocrinal disorders and medicinal plants continue to play an important role in the management of this disease. In this study, Rosa canina was investigated for the antioxidant and α-amylase inhibition activities. Materials and Methods Methanolic extract of Rosa canina was investigated for its...

Introduction: In populations at risk for obesity, knowledge of body composition of children is important for the assessment of nutritional status and its evolution. The aim of our study was to compare body composition determined by two techniques, the electrical impedance and deuterium dilution. Materials and Methods: Our study included 77 students...

Background A National Survey on the Effect of Nutrition conducted in 1996−1997 showed a 14% overall prevalence of obesity in Tunisia with a female predominance. Leptin and ghrelin play crucial roles in regulating body weight and energy balance. Leptin, an anorectic hormone, and ghrelin, an orexigenic hormone, appear to interact with glucose and lip...

At the obese diabetic ones, there’s a disturbance of lipid parameters from where the installation of an insulin resistance responsible for the development of non-insulin-dependent diabetes. Objectives: Our objectives were to evaluate the levels of insulin, leptin and oxidized LDL, and to search the link which could exist between these parameters an...

Background: Multiple medication use is especially common in those with diabetes aged due to multiple illnesses, certain chronic diseases and disabling of the growing demand for care, treatment advances, but also some over-prescription. Aims: To assess the achievement of treatment goals in a population of older diabetics, to analyze drug consumpt...

Background: In an effort to slow the deterioration of renal function, several authors have recommended in the diabetic stage renal disease with moderate renal impairment decreased protein intake to 0.7 or 0.3 g / kg / day associated with energy intake of at least 30 to 35 kcal / kg / day. However, in clinical practice this proved difficult to achi...

Background Obesity in children is a public health problem around the world. Its pathogenesis is not yet elucidated. The fatty tissue, a long time considered as a structure of storage, is now recognized as an endocrine structure, secreting adipokines which would participate in the genesis of obesity. The correlation between the leptin and obesity is...

The change of the way of life and the food practices in Tunisia due inter alia to the improvement of the socioeconomic conditions induced low fuel consumption of food with significant nutritional interest such as those rich in food fibres which have positive effects on the reduction and the prevention of some complications of the metabolic diseases...

We assessed the knowledge attitudes and practices of primiparous women with regard to exclusive breastfeeding and the use of formula milk. A total of 260 women were interviewed and the results showed that 41.5% of the women breastfed exclusively while 58.5% bottle-fed only or did so together with breastfeeding. Of those who breastfed, 43.0% did not...

At the obese ones, there is an imbalance between the free defenses antioxydants and radicals from where the installation of an oxydative stress, responsible for the development of non-insulin-dependent diabetes. Our objectives was to evaluate the levels of vitamins A, E and of leptin, to search the link witch could exist between vitamins and leptin...

Giving up the Father Has islam tried to meet its spiritual structure with a ressouncement of the father tou constitue faith in God ? From that question, this study porposes a way for reading the symbolic islamic construction. From the requirement that God is separated from any paternal metaphore and from any idea of procreation, we have tried in ou...

The increase of the prevalence of the obesity in childhood puts in reason some factors of the environment and the way of life of the child that encourage the hold of weight at these topics of as much more that if they are exposed genetically. A prospective survey has been done close to 3148 school boy aged of 6 to 10 years and who were schooled in...
