Early Puberty in Girls May be a Result of Obesity in Mothers’

Maternal overweight and hyperglycemia or high blood sugar are linked to the earlier onset of puberty in girls, which can lead to multiple adverse health developments in adulthood, finds a study. The results showed that maternal obesity (body mass index of 30 or more) and overweight (body mass index between 25 and 30) in mothers was associated with 40 per cent and 20 per cent greater chance of earlier breast development in girls aged 6 to 11, respectively.

Maternal overweight and hyperglycemia or high blood sugar are linked to the earlier onset of puberty in girls, which can lead to multiple adverse health developments in adulthood, finds a study.

The results showed that maternal obesity (body mass index of 30 or more) and overweight (body mass index between 25 and 30) in mothers was associated with 40 per cent and 20 per cent greater chance of earlier breast development in girls aged 6 to 11, respectively.

“We know that maternal weight can influence childhood weight. What we are learning is that the utero environment may also affect the timing of future pubertal development in offspring, which makes sense since human brains are developed in utero and the brain releases hormones affecting puberty,” said lead author Ai Kubo, research scientist with the Kaiser Permanente Northern California Division of Research.

The study also found a significant relationship between hyperglycemia (elevated blood sugar during pregnancy) in mothers and the earlier onset of breast development, but not in mothers with gestational diabetes.

Similar associations between maternal obesity and earlier onset were also linked with the development of pubic hair.

The study also found a significant relationship between hyperglycemia (elevated blood sugar during pregnancy) in mothers and the earlier onset of breast development, but not in mothers with gestational diabetes.

“It’s possible that women with the diagnosis of gestational diabetes were more careful about weight and diet, which might have changed the amount of weight gain and offspring development patterns, but other studies need to replicate the finding to be able to conclude that there is an association,” Kubo noted.

For the study, published in the American Journal of Epidemiology, the team included more than 15,000 girls and their mothers.

Previous researches have demonstrated that early puberty, including the early onset of breast development or menarche (initiation of menstruation), increases the risk of adverse health outcomes including obesity, Type 2 diabetes, polycystic ovarian syndrome, and cancer in adolescence and adulthood.

For girls, it has been linked to a higher risk of adverse emotional and behavioural outcomes including depression, anxiety, earlier sexual initiation and pregnancy. (IANS)

Exposure to Certain Disinfectants Can Cause Obesity in Kids: Research

The use of eco-friendly products may be linked to healthier overall maternal lifestyles and eating habits.

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.

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.

“When they were 3 years old, their body mass index was higher than children not exposed to heavy home use of disinfectants as an infant,” Kozyrskyj said.

“Those infants growing up in households with heavy use of eco cleaners had much lower levels of the gut microbes Enterobacteriaceae,” she said.

Kozyrskyj suggests that the use of eco-friendly products may be linked to healthier overall maternal lifestyles and eating habits, contributing in turn to the healthier gut microbiomes and weight of their infants. (IANS)
