According to a study, recently published in the journal Psychological Science, the more time you spent with your best friends in childhood, the likelier you have a healthy weight and blood pressure in adulthood.
For the study, the researchers analyzed data from a large study of 267 adults whose social lives were monitored between the ages of 6 and 16. The results of the analysis showed that adults who used to spend a lot of time with their buddies in childhood had lower blood pressure levels and body mass index (BMI) at the age 32.
Jenny M. Cundiff, one of the study authors from Texas Tech University in Lubbock, USA, says: “These findings suggest that our early social lives may have a small protective influence on our physical health in adulthood, and it’s not just our caregivers or financial circumstances, but also friends who may be health protective.”
A new study, whose findings were presented at American Association for Cancer Research Special Conference, finds that women within a normal weight range may be under the greater risk of breast cancer if their levels of body fat are too high.
For the study, a team of scientists analyzed data from 3,460 participants with a normal BMI (body mass index) with no previous diagnosis of breast cancer. The participants were followed up for about 16 years, and if the diagnosis of cancer was made, the participants were further assessed for estrogen receptor positivity.
Having analyzed the received data, the scientists found that the women with normal BMI but a high level of body fat were almost twice more likely to develop breast cancer.
Study author Dr. Neil Iyengar of Memorial Sloan Kettering Cancer Center in New York City says: “Our findings show that the risk of invasive breast cancer is increased in postmenstrual women with normal BMI and higher levels of body fat, meaning that a large proportion of the population has an unrecognized risk of developing cancer.”
A new study, conducted by a pair of US economists, suggests that being in a social network with a higher level of obesity puts people at risk of increasing body mass index (BMI).
The study was conducted on families living on military bases. The researchers found that exposure to communities with higher rates of obesity was associated with higher BMI in parents and children.
With the help of data from the Military Teenagers’ Environments, Exercise, and Nutrition Study, the scientists combined details on 1,111 young adolescents and more than 1,300 parents assigned to one of 12 military bases in the US.
The authors explain in their report: “While this study cannot definitively rule out the role of shared environments with the available measures, these findings suggest that other mechanisms may be at work.”
