The overweight rate was significantly different in all years (χ2 = 10.82, P <0.01) With an average of 1.59%. There was no significant difference between years (χ2 = 1.12, P> 0.05). The malnutrition rate was significantly higher in girls (46.64%) than in boys (30.99%). The rates of overweight (5.58%) and obesity (2.38%) were higher in boys than in girls (3.34%, 0.91%, P <0.01).
