Development and validation of anthropometric predictive equations that estimate the total body water and fat-free mass in Tunisian adults.

Objective: To develop and validate equations that estimate total body water (TBW) and fat-free mass (FFM) in adults using anthropometric measurements.

Methods: A cross-sectional study was conducted among 178 adults (77 men and 101 women; aged 18-59 years). Participants were distributed by sex and age groups, and then randomly assigned to equal two groups; the development (n = 89) and the validation (n = 89).

Relevance of body mass index and bioelectrical impedance analysis vs. deuterium dilution technique to assess excess of fat among young adults.

Our study aimed to assess the nutritional status by using body composition among young Tunisian adults through three measurement methods: body mass index (BMI), bioelectrical impedance analysis (BIA) and deuterium oxide dilution technique (HO) and to determine the accuracy of BMI and BIA in order to evaluate the overweight and obesity among young adults in Tunisia. Our study involved 144 young adults. Anthropometric parameters were measured.

Physical Activity Level Assessed by Accelerometer and PAQ-C in Tunisian Children.

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.
