Women who breastfeed for five months likely to have more kids

Turns out, women who breastfeed their first child for five months or longer are more likely to have more children as compared to women who breastfeed for shorter durations or not at all.

BS| Cornell University professor of sociology Vida Maralani, with Hunter College professor Samuel Stabler, reported that women who initiate breastfeeding did not differ in how many children they expected to have before they started their families.
Rather, the number of children women actually bear differs by how long they breastfeed their first child. Women who breastfeed for shorter durations are more likely to have fewer children than they expected, while women who breastfeed longer are as likely to achieve their expectations to exceed them.
The researchers caution that their results do not imply that breastfeeding duration causes women to have larger families. They write, “Our study reveals the opposite: the interconnectedness of family preferences and child investment across the life course.”
“Women hear the strong message that they should breastfeed their infants for the first year of life, yet it is unambiguously clear that they find these guidelines difficult to follow in practice,” said Maralani.
The researchers used a nationally representative longitudinal dataset, from 1979 to 2012, which provides information on a cohort of nearly 3,700 mothers. They measured women’s expected fertility at least one year before women conceived their first child to examine the link between their expectations of future fertility and actual behavior.
These data also enabled the authors to account for differences in breastfeeding and fertility by education, age, marital status, family income, and work histories.

How common household cleaners could make kids overweight

Early life exposure to certain disinfectants used at home could be making children overweight by altering the composition of their gut bacteria, suggests new research.

Babies living in households that used eco-friendly cleaners had different microbiota and were less likely to be overweight as toddlers, showed the findings published in CMAJ (Canadian Medical Association Journal).
For the study, the researchers analysed the gut flora of 757 infants from the general population at age 3-4 months and weight at ages 1 and 3 years, looking at exposure to disinfectants, detergents and eco-friendly products used in the home.
The researchers looked at data from the Canadian Healthy Infant Longitudinal Development (CHILD) birth cohort on microbes in infant fecal matter. They used World Health Organization growth charts for body mass index (BMI) scores.|Household cleaners
Associations with altered gut flora in babies 3-4 months old were strongest for frequent use of household disinfectants such as multi-surface cleaners, which showed lower levels of Haemophilus and Clostridium bacteria but higher levels of Lachnospiraceae.
The researchers also observed an increase in Lachnospiraceae bacteria with more frequent cleaning with disinfectants.
They, however, did not find the same association with detergents or eco-friendly cleaners.
“We found that infants living in households with disinfectants being used at least weekly were twice as likely to have higher levels of the gut microbes Lachnospiraceae at age 3-4 months,” said Anita Kozyrskyj, Professor at the University of Alberta in Canada.
