Introduction: Working at an early age can have adverse consequences on health. Working children due to their occupational hazards are at risk of communicable and non-communicable diseases such as malnutrition, anemia and growth retardation. This study aimed to determine the nutritional status and prevalence of anemia in working and non-working children. Methods: This case-control study was carried out as cross-sectional, on 90 working and 90 non-working 8-18 year-old boys in Kermanshah. The data gathering tools were demographic and food frequency questionnaires (FFQ). Anthropometric parameters were measured using standard tools. 5 ml blood for blood biomarkers test was collected from the participants. Results: Average height and weight of working children were respectively 3.7 cm and 5.7 kg less than of the non- working children (P = 0.02). Prevalence of iron deficiency in working children was more than double in the non-working children (28% vs 11.3%, P = 0.01). Hemoglobin concentration was less significantly in working children compare to non-working children (p=0.05). The working children as significantly consumed all of the food groups except the bread and cereals less than the non-working children (P <0.001). Conclusions: Working children are at risk to develop anemia and malnutrition so they need to emergencies nutritional supports.

Abstract
Introduction: With the alternation of the educational system from a three-stage into a two-stage system in Iranian schools since several years ago, five-year-old children entered from kindergartens to primary schools. This study was conducted to investigate the harmonization of classroom furniture with anthropometric dimensions in preschool students. 
Methods: In this study, 366 male and female preschool students were selected by cluster sampling method in Kerman, Iran. The  sample size was calculated by the Cochran formula  Some of the anthropometric dimensions such as shoulder, elbow, and popliteal height, popliteal buttock length, and buttock breath were measured. Data were analyzed using SPSS 21. Statistical indicators such as mean, maximum, minimum, standard division, and 5^th, 50^th, and 95^th percentiles were calculated for both the sexes and were compared with five dimensions of the existing seats. Next, the dimensions of the standard seats were determined according to the anthropometric dimension’s students.
Results: Anthropometric dimensions comparision between girl and boy pre- school students in Kerman city showed just popliteal height had a siginificnt diference (p ≤0.05). Match of antropometric musurmants with seat dimentions indicated that there is no consistency between the seats and anthropometric dimensions in. Armrest height, seat height, backrest height, seat depth and seat breath were matched with (0, 0.5, 10, 6.7, 0) and (0.7, 28.7, 6, 2.5, 0) percent of anthropometric musurments of girl and boy students respectively
Conclusions: Due to adding a new grade to primary school, it seems that no work has been done for improving the furniture. Therefore, in this article, we presented the dimensions of an appropriate seat. This may help not only save production costs in the industry but also increase the matching between students' anthropometric and seat dimensions.
