Childhood lead exposure is a risk factor for criminal behavior

Prenatal and postnatal blood lead concentrations are associated with higher rates of total arrests and/or arrests for offenses involving violence. This is the first prospective study to demonstrate an association between developmental exposure to lead and adult criminal behavior. – Lead exposure during childhood is associated with adult criminal behaviour, including violent crime, revealed by researchers in this week’s PLoS Medicine. Childhood lead exposure is a purported risk factor for antisocial behavior, but prior studies either relied on indirect measures of exposure or did not follow participants into adulthood to examine the relationship between lead exposure and criminal activity in young adults.

Less folate in diet cause abnormal sperm

Healthy men who report lower levels of the nutrient folate in their diets have higher rates of chromosomal abnormalities in their sperm. – Healthy men who report lower levels of the nutrient folate in their diets have higher rates of chromosomal abnormalities in their sperm, according to a new study by researchers at the University of California, Berkeley, and the Lawrence Berkeley National Laboratory.

Quit smoking in pregnancy to have easy going child

Meaningful differences in maternal smoking behavior during pregnancy: implications for infant behavioral vulnerability – Giving up smoking during pregnancy may boost the chances of giving birth to an easy going child, indicates research in the Journal of Epidemiology and Community Health.

Zebrafish offer useful screening tool for genes, drugs that protect against hearing loss

A small striped fish is helping scientists understand what makes people susceptible to a common form of hearing loss, although, in this case, it?s not the fish?s ears that are of interest. – A small striped fish is helping scientists understand what makes people susceptible to a common form of hearing loss, although, in this case, it’s not the fish’s ears that are of interest. In a study published in the Feb. 29 issue of the journal PLoS Genetics, researchers at the University of Washington have developed a research method that relies on a zebrafish’s lateral line-the faint line running down each side of a fish that enables it to sense its surroundings-to quickly screen for genes and chemical compounds that protect against hearing loss from some medications.

Kinship of couples may determine number of children

deCODE links closer kinship with reproductive success. Phenomenon could have long-term impact on population growth in urbanizing societies. – In a paper published by deCODE genetics (Nasdaq:DCGN) scientists establish a substantial and consistent positive correlation between the kinship of couples and the number of children and grandchildren they have.

Overweight pregnant women may have fatter children

Obesity, overweight during pregnancy may be more likely to have fatter children susceptible to chronic health problems. – Mothers-to-be beware. Women who are overweight during pregnancy may be more likely to have fatter children susceptible to chronic health problems, University of New South Wales (UNSW) research shows.

Prenatal starvation may lead to addiction later in life

Babies conceived during a period of famine are at risk of developing addictions later in life, according to new research published in the international journal Addiction. – Babies conceived during a period of famine are at risk of developing addictions later in life, and a range of chronic disorders including physical conditions such as coronary heart disease, and psychiatric ones such as schizophrenia and clinical depression.

Vitamin D deficiency may increase heart disease risk

Vitamin D deficiency is associated with incident cardiovascular disease. Further clinical and experimental studies may be warranted to determine whether correction of vitamin D deficiency could contribute to the prevention of cardiovascular disease. – The same vitamin D deficiency that can result in weak bones now has been associated with an increased risk of cardiovascular disease, Framingham Heart Study researchers report in Circulation: Journal of the American Heart Association.

Obese pregnant women give birth to heavier babies

New study suggests that maternal body composition at or near conception has important implications for offspring?s obesity, and obesity during conception phase may set the stage for offspring?s obesity risk. – The number of overweight and obese Americans continues to grow rapidly. Today, 50 percent of adults are overweight and up to 20 percent are obese. While the number of overweight/obese children is at an all time high, the steady increase of overweight infants ? individuals under 11 months old ? is alarming.

Aging improves parent, child relationships

Most parents and children are fortunate to share several decades of the life course when both parties are healthy adults. When parents reach the transition to old age, however, they typically experience health declines, and both parties must adjust to changes in the relationship.
– The majority of relationships between parents and their adult children improve as parents transition to old age, a Purdue University researcher has found. Karen Fingerman, an associate professor of developmental and family studies in the College of Consumer and Family Sciences, examined relationships adults 70 and older have with at least one of their adult offspring.
