Background & Objectives : Smoking is one of the major problems in the world today. It threatens people ’ s health. Pregnant women are no exception in this regard. Today, it is found that smoker women bear low birth weight babies, but the studies don ’ t offer clear findings about passive smoking in pregnancy and its effect on weight and height of newborns. This study is an attempt to determine the effects of passive smoking on the weight and height of the newborn babies.

  M ethods : This was a retrospective cohort study. We studied 100 pregnant mothers who were exposed to cigarette smoke and 100 others who were not. A checklist was completed in order to select those who could enter the study. A questionnaire was then filled out for both groups including the information related to the newborns ’ physical specifications.

  Results: This study showed that the average age of the mothers, their education, their husband ’ s education, number of pregnancies and the sex of babies born weren ’ t meaningfully different between the two groups. In the case group the mothers were exposed to cigarette smoke for 2.36 ± 2.28 hours on average and most of them (72%) were exposed to their husbands ’ cigarette smoke. The findings also indicated that difference in weight, height and head circumference among two groups ’ newborns were 11 grams, 0.15 cm and 0.02 cm respectively. The T-test indicated no significant difference between the two groups.

  Conclusion: The study showed that the newborns ’ of mothers exposed to the smoke had lower weigh, height and head circumference than the babies ’ of the control group subjects although the difference was not statistically significant.

 Background & Objectives: Measurement of body Weight and height and determining of body mass index (BMI) according to age is one of the most important international indicators for evaluation of growth and physical health. The present study aimed to evaluate growth indices for schoolgirls 7-19 years of age living in Ardabil to compare with standard reference values and similar studies in Iran .

 Methods: To assess the status of growth pattern of 7-19 year girls in Ardebil during 2005, with a descriptive cross-sectional study, 3996 healthy girls were selected by the multi stage sampling method and their age, body weight, height and body mass index were recorded, then 5,10,25,50,75,90,95 percentile, mean and standard deviation in different age were analyzed and compared with NCHS and selected regions of Iran

 Results: The mean of Height and weight in urban girls is higher than their peers in rural regions. Height growth was more during the ages of 9-12 with its peakin 9 years olds with 6 cm annually. The highest increase in weight was at age13 which was estimated 5.5 kg annually. Mean of height and weight in girls of Ardabil is less than their peers in Tehran, Kerman, Esfahan but more than their peers in Zahedan. Of the height, weight and body mass index percentiles in girls of Ardabil aged 7-19 years were less than their American peers according to National Center for Health Statistics data.

 Conclusion: All of percentiles anthropometric factors in girls Ardabil aged 7-19 years were less than NCHS standard.
