Neonatal growth indices are one of the important issues in the assessment
and care of pregnancy which have significant effects on the life after birth.
Therefore, it is important to recognize their related factors. The aim of this
study was to investigate the relationship between pregnant women's lifestyle
and physical growth indices in newborns. This descriptive-comparative
study was conducted on 412 pregnant women (mean age 28.1±5.6 years)
who referred to Mahdieh Hospital in Tehran by a cross-sectional and field
method. Subjects were selected by convenience sampling method. Data were
collected and recorded by Lifestyle Questionnaire (LSQ) and information
about the growth indices of newborns from their medical records in Tehran
Mahdieh Hospital. Then, growth indices were compared with NCHS
standard norm (P≤0.05). Independent and one-sample t tests and Pearson
correlation were used to analyze the data. According to the results, the
quality of lifestyle in pregnant women was reported to be moderate. Also, a
comparison of weight and height indices showed a significant difference in
the time intervals after birth in comparison with the NCHS norm (P≤0.05)
which indicated that this norm was lower than the global norm in Iranian
infants. On the other hand, no significant difference was observed in the
head circumference (P=0.18). Considering the findings of this study on
lifestyle and moderate physical activity in pregnant women, mothers are
recommended to have more physical activity and to improve their nutritional
quality so that they can promote their lifestyle and thereby improve the
growth indices of newborns.
