    Aim

    Since the mismatch between the anthropometric dimensions of individuals and the dimensions of hand tools and shoes which leads to musculoskeletal disorders (MSDs), measuring data on anthropometric dimensions of hands and feet is essential for designing hand tools and shoes production. This study aimed to measure the anthropometric dimensions of hands and feet in different ages of men and women in Tabriz, Iran.

    Method and Materials

    This is a descriptive-analytical study that was conducted in 2020 on 609 peoples living in Tabriz city in Iran. In this study, two and one dimensions of foot and hand were measured manually respectively. Descriptive statistics such as percentages, means, and standard deviation were calculated. Independent t-test and Cohen effect size were used to test the mean dimensions of hands and feet of subjects .

    Finding

    Mean, standard deviation and 5th, 50th and 95th percentiles values were calculated in general and in terms of gender and educational level for individuals. In all the measured dimensions, men were generally larger than women, however; there were exceptions. The mean of the measured dimensions of hand foot size between men and women was different significantly.

    Conclusion

    In this study, anthropometric data of hands and feet for people living in Tabriz were measured. The findings provided can be used to design hand tools and shoes productions.

    Background
    Recent surge in the diagnoses of congenital hypothyroidism (CH) has necessitated the measurement of newborn TSH levels and understanding of the way various antenatal and perinatal factors influence its dynamicity. It is a cross-sectional study on newborns delivered or admitted to the All India Institute of Medical Sciences Raipur (AIIMS Raipur), Chhattisgarh, India.
    Methods
    Dried blood spot analysis of newborn thyroid-stimulating hormone (nTSH) was carried out on 1,216 newborns after ethical clearance. The TSH levels were presented in percentage to determine the distribution in the study population. The mean values were compared within the groups categorized under each variable. The newborns' variables in this study included birth weight, Ponderal index, and neonatal complications. The studied maternal variables included antenatal visits, maternal age, gestational age, anemia, and mode of delivery.
    Results
    The mean (standard error of the mean) for nTSH was obtained at 3.37 (0.12) mIU/L and 97% of newborns were below 8 mIU/L. Mean nTSH was significantly high in mothers older than 30 years (P=0.019) and those with anemia during the antenatal period (p <0.001). It was significantly raised in babies with complications (P=0.004). Besides, higher values were also observed in low birth weight babies and those with low Ponderal Index. Higher nTSH was observed among newborns born to mothers with a thyroid disorder, those delivered prematurely and/or by cesarean section, and those with no antenatal visits.
    Conclusion
    It is highly essential to take a precautionary note on the antenatal status of mothers in terms of advanced age, premature delivery, associated maternal diseases, mode of delivery, newborn’s birth weight, and complications which are supposed to influence the dynamicity of thyroid hormones in newborns and result in CH.

    زمینه و هدف

    استفاده از میز و صندلی آموزشی با طراحی مناسب علاوه بر یادگیری مناسب، می تواند از تغییرات فرم بدن کاربر جلوگیری کند. لذا هدف از این مطالعه، تعیین مشخصه های آنتروپومتری دانشجویان پردیس کشاورزی و منابع طبیعی دانشگاه تهران جهت طراحی میز و صندلی ارگونومی بود.

    روش کار

    در این پژوهش، 18 مشخصه آنتروپومتری شامل: ارتفاع رکبی، ارتفاع زانو نشسته، ارتفاع شانه نشسته، ارتفاع چشم نشسته، ارتفاع نشسته، ارتفاع تکیه گاه آرنج نشسته، ارتفاع آرنج نشسته، طول آرنج - مشت گره کرده، طول باسن - رکبی، طول باسن- زانو نشسته، ضخامت ران، عمق شکم، عمق سینه، پهنای باسن نشسته، پهنای شانه، پهنای عرضی آرنج ها، قد و همچنین وزن برای 260 نفر از دانشجویان (130 دختر و 130 پسر) با رده سنی 18 تا 35 سال موردبررسی قرار گرفتند. جهت جمع آوری داده ها، از استادیومتر و صندلی آنتروپومتری استفاده شد. درنهایت با توجه به ابعاد بدنی اندازه گیری شده از دانشجویان، ابعاد میز و صندلی ارگونومی  مطابق با استاندارد 9697-1 INSO محاسبه و طراحی گردید.

    یافته ها:

     ابعاد آنتروپومتری دانشجویان به صورت میانگین، حداقل، حداکثر، انحراف معیار، میانه و مقدار صدک های 5/2 تا 5/97 با نرم افزار SPSS نسخه 20 به دست آمد. نتایج نشان دادند سن کاربر بر روی سایزبندی میز و صندلی اثر معنی داری ندارد. همچنین نتایج حاصله نشان داد ارتفاع رکبی بین دختران و پسران دارای اختلاف معنی داری می باشد.

     نتیجه گیری:

     با در نظر گرفتن اختلاف ابعادی بین دانشجویان دختر و پسر مشخص شد که ارتفاع رکبی در صدک 5 برای پسران 4 سانتی متر بیشتر از دختران می باشد. لذا با استفاده از ابعاد آنتروپومتری اندازه گیری شده، ابعاد میز و صندلی ارگونومی در دو سایز طراحی شد.

    Background and Aim

    A well-designed desk and chair, in addition to proper learning, can prevent changes in the userchr('39')s physical form. Therefore, this study aimed to determine the anthropometric characteristics of students in the College of Agriculture and Natural Resources located at the University of Tehran to design an ergonomic table and chair.

    Methods

    In this research, 18 anthropometric characteristics including the popliteal height, knee height, shoulder height, eye height, sitting height, elbow support height, elbow height, knotted elbow length, hip-popliteal length, hip-knee length, thigh thickness, abdominal depth, chest depth, hip width, shoulder width, the transverse width of the elbows, height, and as well as weight for 260 students (130 girls and 130 boys) aged 18 to 35 years were investigated. To collect data, an anthropometric chamber and chair were used. Finally, according to the measured physical dimensions of the students, the Dimensions of ergonomic table and chair were calculated and designed according to the INSO 9697-1 standard.

    Results

    Anthropometric dimensions of students were obtained through mean, minimum, maximum, standard deviation, mean, and the percentile value of 2.5 to 97.5 using SPSS version 20 software. The results showed that the age of the user does not have a significant effect on the size of the table and the chair. Also, the results showed that there was a significant difference in popliteal height between girls and boys.

    Conclusions

    Considering the difference in dimensions between female and male students, it was found that the popliteal height in the percentile of 5 for boys is 4 cm more than girls. Therefore, using measured anthropometric characteristics, the dimensions of the chair and table ergonomics were designed in two sizes.

    Background
    This study aim to determine the association between height and cancer in the children aged 14 years at the time of diagnosis in Rasht, Iran.
    Materials And Methods
    In this cross-sectional study, height of patients with a malignancy (≤14) at the time of diagnosis measured in the standard charts of United States National Center for the Health Statistics (NCHS). Data were reported by descriptive statistics and analyzed by Regression tests in SPSS version 19.
    Results
    Overall, 78 male (38.6%) and 124 female (61.4%) patients with various kinds of malignancies were evaluated for their heights. Leukemia was the most common type of cancer. The median height of the patients was more than 20th percentile and under 50th percentile of the NCHS. No significant association was found between height and leukemia.
    Conclusion
    Previously, the median height of Iranian girls and boys (≤15) reported under 20th percentile of the NCHS. In this study, the median height of the patients at the time of diagnosis was more than 20th percentile of the NCHS. There was a correlation between height and cancer among our patients, although, this correlation can be assessed by further cohort study.
