Hypothesis
The study aims to show the effect of pre-pregnancy body mass index and gestational weight gain on pregnancy outcomes.
Conclusion
Low pre-pregnancy BMI and abnormal gestational weight gain are significant risk factors for low birth weight in newborns.
Supporting Evidence
- Low pre-pregnancy BMI is linked to higher rates of low birth weight.
- Abnormal weight gain during pregnancy is associated with low birth weight.
- The majority of participants did not achieve recommended weight gain during pregnancy.
Takeaway
If a mom is too thin before getting pregnant or gains too much or too little weight during pregnancy, her baby might be born too small.
Methodology
A prospective cross-sectional study involving 270 women in their first eight weeks of pregnancy, analyzing weight gain and pregnancy outcomes.
Potential Biases
Potential bias due to self-reported pre-pregnancy weight and lack of intervention during pregnancy.
Limitations
The study did not analyze weight fluctuations weekly, which may have affected the assessment of weight gain.
Participant Demographics
Mean age of participants was 32.3 years, with 85.2% aged 19-35, 79.1% multiparous, and 24.1% illiterate.
