This page organizes the supporting evidence for each BabyQ question. It is designed as an educational resource for expectant mothers, doulas, and midwives.
Why this matters: No safe amount of alcohol has been established in pregnancy. Even low levels can impair brain development and increase risks of miscarriage, preterm birth, and fetal alcohol spectrum disorders (FASD).
Why this matters: Smoking increases the risk of miscarriage, stillbirth, preterm birth, and sudden infant death syndrome (SIDS). Nicotine replacement therapy (NRT) is safer than continued smoking and can be used under medical guidance.
Why this matters: Sleep less than 7 hours increases risks of preterm birth, cesarean delivery, and hypertension. Quality rest supports maternal health, labor outcomes, and infant growth.
Why this matters: Regular prenatal visits reduce risks of maternal and infant mortality, allow early detection of complications, and provide preventive care such as screenings and vaccinations.
Why this matters: Exercise lowers the risk of gestational diabetes, preeclampsia, and excessive weight gain. Occupational standing ≠ exercise — leisure activity is what matters.
Why this matters: Adequate protein supports fetal growth, maternal blood supply, and placental health. Needs rise in the 2nd and 3rd trimesters.
Why this matters: High sugar intake raises risks of gestational diabetes, excessive weight gain, and childhood obesity. Sugary beverages are especially harmful.
Why this matters: Depression in pregnancy increases risks of preterm birth, low birth weight, and postpartum depression. Early identification and treatment are protective.
Why this matters: Vegetables provide folate, iron, vitamin K, and antioxidants crucial for fetal development and preeclampsia prevention. Leafy greens and cruciferous vegetables are especially protective.
Why this matters: Strong social support reduces risks of preterm birth, low birth weight, and postpartum depression. Lack of support elevates stress hormones harmful to pregnancy.
Why this matters: Frequent stress (>1x/week) doubles the risk of preterm birth. Effective coping and stress management protect maternal health and fetal growth.
Why this matters: Periodontal disease is linked to preterm birth and preeclampsia. Preventive dental care is safe in pregnancy and helps reduce systemic inflammation.
Why this matters: Adequate folic acid prevents neural tube defects by 50–70%. Prenatals also provide iron, vitamin D, iodine, and DHA that support maternal and fetal health.
Why this matters: Dairy provides calcium, protein, and probiotics. Adequate calcium prevents maternal bone loss and supports fetal skeletal growth. Fermented dairy reduces risk of preeclampsia and gestational diabetes.
Why this matters: Whole grains reduce risks of gestational diabetes, preterm birth, and excessive maternal weight gain. Fiber also supports digestive health and improves microbiome diversity.
