Insights
Maternal gestational weight gain significantly impacts infant birth weight. Adequate weight gain during pregnancy is crucial for healthy infant development and may reduce risks of adult-onset diseases.
Area of Science:
- Maternal and Child Health
- Public Health Nutrition
- Obstetrics
Background:
- Low birth weight is a risk factor for adult-onset diseases like type-2 diabetes and ischemic heart disease.
- Maternal weight gain is a key predictor of infant birth weight.
- Recommendations exist for maternal weight gain based on prepregnancy body mass index (BMI).
Purpose of the Study:
- To examine the total weight gained by pregnant women.
- To determine the correlation between maternal weight gain and infant birth weight.
Main Methods:
- A study involving 98 women delivering full-term single infants at Patan hospital.
- Data collected from hospital records and self-reported information on income, diet, birth spacing, and work.
- Statistical analysis using Multiple Linear Regression Models and stepwise multiple regressions.
Main Results:
- The mean maternal weight gain was 9.48 kg (SD = 3.41).
- The mean infant birth weight was 2965.66 g (SD = 364.37).
- Gestational weight gain and maternal age were identified as significant factors influencing infant birth weight.
Conclusions:
- Gestational weight gain demonstrates a positive linear relationship with infant birth weight.
- Ensuring appropriate gestational weight gain is vital for optimal infant birth weight.
- Further research can explore the impact of other factors on birth outcomes.
Abstract:
Birth weight is an important determinant of infant's well being as low birth weight is known to increase the risk adult onset of diseases like type-2 diabetes and ischemic heart disease. Maternal weight gain is one of the most important independent predictors of infant birth weight. Institute of Medicine of the National Academics, USA has recommended that total weight gain of mothers should be according to their prepregnancy body mass index (BMI). Therefore, this study was conducted to observe the total weight gained by the pregnant women and the correlation between the weights gained by them with the birth weight of their infants. 98 women who delivered full term single baby at Patan hospital were included after taking their verbal consent. The details of the newborn and the history of the pregnant women were taken from the hospital records. The information about the family income, dietary habit, birth spacing and the type of work done by the pregnant women was obtained from the women themselves. The mean weight gain of the mothers was 9.48 (SD = 3.41) kilograms and the mean birth weight of the infants was found to be 2965.66 (SD = 364.37) grams. Multiple Liner Regression Models showed the effect of Gestational weight gain (GWG), Age and Parity on birth weight of the infant. Step-wise multiple regressions gave rise to models that showed effect of GWG and age on birth weight of the infants. This study concluded that gestational weight gain has positive linear relationship (correlation) with the birth weight of infants.

Coefficient of Correlation
If you suspect a linear relationship between x and y, then r can measure how strong the linear relationship is.
What the VALUE of r tells us:
The value of r is always between –1 and +1: –1 ≤ r ≤ 1.
The size of the correlation r indicates the strength of the linear...
