Breastfeeding may curb heart,diabetes risk factors
Women who breastfeed have a lower long-term risk of developing a collection of risk factors for diabetes and heart disease than women who bottle-feed,found researchers from Kaiser Permanentes Division of Research in Oakland,California. Among 700 women followed for 20 years,those who had breastfed were less likely to develop metabolic syndrome a cluster of risk factors for type 2 diabetes and heart disease,which includes abdominal obesity,elevated blood pressure and blood sugar,lower-than-desirable levels of good cholesterol. The protective effect was stronger among women with a history of gestational diabetes,which arises during pregnancy and goes away after childbirth,said the study published online in Diabetes.

Birth weight,early weight gain may hasten puberty
A relatively low birth weight and early-age weight gain may increase the likelihood of early puberty,hint findings from a German study. Early onset of puberty has been linked to certain cancers,high blood sugar and obesity,say researchers from Fulda University of Applied Sciences in Fulda. The study,published in the American Journal of Clinical Nutrition,suggests the onset of puberty may occur from 4 to 7 months earlier among boys and girls who weighed less than normal at birth and rapidly gained weight from birth through the age of 2. The research involved 215 children who were part of a nutrition and growth study.

Life may be shorter in poorer neighborhoods
Residents of poor neighbourhoods may die sooner than those in wealthier neighbourhoods regardless of what they eat,how active they are,or other individual risk factors. This finding that where you live might affect how long you live comes from a study of over 565,000 people enrolled in the NIH-AARP Diet and Health Study. Neighbourhood characteristics were drawn from US census data for 2000. There is an increased risk of death from any cause or cancer in socioeconomically deprived neighbourhoods,the researchers said at the American Association for Cancer Research Conference in Houston.

Exercise can benefit men with prostate cancer
As little as 15 minutes of physical activity a day can substantially cut death rates in men with prostate cancer. Researchers from Harvard School of Public Health,Boston,recommended men with prostate cancer do some physical activity,even if it is 15 minutes per day,of walking,jogging,biking,or mild gardening. Vigorous activity may be beneficial for prostate cancer and overall health. The findings stem from following 2,686 men with prostate cancer from 1986 to 2008. Prostate cancer patients who engaged in physical activities for about a half-hour per week had a 22 per cent reduction in risk of death,the researchers found.
