Summary
Maternal characteristics like weight, income, and physical activity significantly influence infant birth weight (IBW). Understanding these factors is crucial for optimal perinatal care and infant development.
Area of Science:
- Obstetrics and Gynecology
- Pediatrics
- Public Health
Background:
- Infant birth weight (IBW) is a critical determinant of a child's future physical and mental development.
- Maternal characteristics are increasingly recognized as significant factors influencing IBW.
Purpose of the Study:
- To investigate the relationship between maternal characteristics and infant birth weight (IBW).
- To identify key maternal factors associated with IBW in pregnant women in Qazvin city.
Main Methods:
- A descriptive-analytical study was conducted on pregnant women (28-36 weeks gestation).
- Data were collected from healthcare centers in Qazvin city between April-June 2016.
- Linear and logistic regression analyses were used to examine associations between maternal factors and IBW.
Main Results:
- Maternal weight, income, gestational age at delivery, and pre-pregnancy BMI were positively associated with IBW.
- Occupational and heavy physical activity were negatively associated with IBW.
- Mothers engaging in heavy physical activity or having lower pre-pregnancy BMI, gestational age, weight, and income had infants with lower birth weight.
Conclusions:
- Maternal characteristics play a significant role in determining infant birth weight.
- There is a need for improved counseling on appropriate weight gain and physical activity during pregnancy in developing countries like Iran.
- Providing proper information on perinatal care can lead to optimal pregnancy outcomes.

While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although...

While taking the arithmetic, geometric, or harmonic mean of a sample data set, equal importance is assigned to all the data points. However, all the values may not always be equally important in some data sets. An intrinsic bias might make it more important to give more weightage to specific values over others.
For example, consider the number of goals scored in the matches of a tournament. While computing the average number of goals scored in the tournament, it may be more important to...
