CDC: Women in early 30s have highest birth rate in US
CDC researchers reported that the rate of births to women ages 30 to 34 in the US was nearly 103 per 100,000 in 2016, just above the 102 per 100,000 rate for those ages 25 to 29, who had held the highest birth rates for more than 30 years. The findings also showed that teen birth rates declined between 2015 and 2016 and infant mortality rates remained similar.ABC News/The Associated Press (5/17)
Study links omega-6/3 imbalance to pre-, post-natal depression
Women who don't consume enough omega-3 polyunsaturated fatty acids, particularly those with a higher omega-6/omega-3 ratio, may be at greater risk for pre- and post-natal depression, but omega-3 supplementation may be an effective treatment, according to a meta-analysis
of 12 studies. "Anthropological and epidemiological studies suggest that human beings evolved on a diet with a ratio of n-6/n-3 PUFAs of about 1:1, and modern diets have a ratio of 10-20:1, indicating that modern diets are in a profound imbalance in PUFA composition," the researchers wrote.
