A Mediterranean Intervention on Prediabetic Children

The HbA1c were measured at the initial visit (V0) and during the last visit (V4)

The height of the children was measured via the Omron BF-511 impedance mete, being classified to Melo Sailor's tables of child growth. The measure of the impedance was taken at the initial visit (V0) and at the last visit (V4)

The weight (kg) of the children was measured via the Omron BF-511 impedance mete, being classified to Melo Sailor's tables of child growth. The measure of the impedance was taken at the initial visit (V0) and at the last visit (V4)

The waist circumference (cm) of the children was measured via an inextensible measuring tape at the initial visit (V0) and at the last visit (V4)

The hip circumference(cm) of the children was measured via an inextensible measuring tape at the initial visit (V0) and at the last visit (V4)

The arm circumference (cm) of the children was measured via an inextensible measuring tape at the initial visit (V0) and at the last visit (V4). The measurement follows the recommendations of the International Standards for Anthropometric Assessment

The children's body mass index (kg/m2) was obtained following the World Health Organization's recommendations and guidelines, being classified to Melo Sailor's tables of child growth. The calculation of the BMI was obtained at the initial visit (V0) and the last visit (V4)

The KIDMED was used to determine adherence to the change in diet from the initial visit (V0) and the final visit (V4). This questionnaire is formed by 16 questions related to adherence to the Mediterranean diet, in addition to 7 items complementary to the test. All questions were answered positively or negatively.
