Food quality and nutritional status of school-going adolescents in the province of El Jadida in Morocco

Background. Dietary diversity and variety scores represent tools for measuring the overall quality of diets. In children, they are good indicators of their nutritional status and growth.
Objective. The aim of this study was to assess the consumption and eating habits as well as the lifestyle of Moroccan adolescents attending school in the city of El Jadida.
Material and methods. A sample of 463 children of both sexes, aged 9 to 17, attending four schools in the city of El Jadida was studied. Eating habits and information on socioeconomic level are assessed using questionnaires and weight and height were measured on participants.
Results. According to the dietary diversity score (DDS) classes, 2.4% of the children surveyed were with low DDS, 55.7% moderate and 41.9%, with high DDS. The mean DDS was 5.67 ± 1.03 in underweight children and 5.53 ± 1.5 in those with overweight (obesity included) and the food variety scores (DVS) were of 12.94±3.24 food items and 10.81±3.25 in the 2 groups respectively. In addition, data analyzes show that children from parents with a low level of education had higher averages of DDS and DVS (DDS: 5.54 ± 0.84; SVA: 10.65 ± 2.32) compared to those of parents with medium education level (DDS: 5.31±0.96; DVS: 9.72±2.62) or high level (DDS: 5.17±0.93; DVS: 9.36 ±2.42). In addition, children from parents of high economic level had a lower averages of DDS and DVS (DDS: 5.24 ± 0.88; DVS: 8.84 ± 2.10) compared to those of parents of low economic level (DDS: 5.36±1.00; DVS: 10.14±2.85). The sugary products were consumed by 56.3% of underweiht children, 75% of normal-weight children and 67% of overweight children (including obese).
The estimated total energy intake (TEI) was higher than the Recommended Daily Allowances (RDA) in underweight 2933 Kcal/d and in overweight (including obese) children 3061.75 Kcal/d, while the mean daily intakes of folate, calcium, iron, potassium and zinc were lower than the (RDA). The food groups consumed by the majority of children were cereals (98.5%), fruits and vegetables (87.7%), and sweet products (69.8%) while oilseed products and fat were less consumed (9.7% and 7.8% respectively).
Conclusion. The study data show that the adolescents diet were moderately diverse, little varied and poor in certain nutrients essential for their nutritional status and growth. The study draws attention to the need for parents to be aware of the benefits of improving the diet quality and weight status of adolescents
