In addition to age, gender, body weight, hormonal status as well as certain physiological and pathological states, other factors exert considerable effects on calcium (Ca) retention and therefore on its urinary excretion. Among these other factors, many dietary nutrients have all been discussed as factors affecting urinary Ca through different studies. Thus, our study aims to evaluate the impact of various nutritional factors on urinary Ca excretion among a sample of Moroccan children and adolescents aged from 6 to 18 years old. A total of 133 Moroccan children and adolescents aged between 6 and 18 years were involved in this study. Participants were required from public and private schools in Rabat-Salé-Kenitra region. For each participant, anthropometry data, food record and 24-h urine samples were collected. Urinary Ca was estimated using ICP-mass spectrometry. The urinary Ca average was 73.58±37.13 mg/day. Urinary Ca excretion had no significant association (p>0.05) with different studied nutrients (r=-0.082, r=0.118, r=-0.025, r=0.142, r=0.084, r=0.119 for Ca, proteins, vitamin D, sodium, phosphorus and magnesium intakes respectively).The current impact evaluation of various nutritional factors on urinary Ca excretion suggests that Ca requirement may be not influenced by nutrients intake but it is highly recommended for researchers to carry out more studies and define all factors that cause Ca deficiency in Moroccan children and adolescents.
