Three-fourths of all moms in the U.S. are struggling with some degree of mental health issues. A study published yesterday by Columbia University looked at nearly 200-thousand mothers over a seven-year period, and found only 25-percent reporting "excellent" mental health. That's down from 38-percent in 2016. The study also showed declines in physical health among U.S. mothers, especially among those who were single, younger, less educated and whose children were multi-racial or uninsured.
