Study finds continual increase in bed sharing among black, hispanic infants

2013-10-01
(Press-News.org) The proportion of infants bed sharing with caregivers increased between 1993 and 2010, especially among black and Hispanic families, according to a study published by JAMA Pediatrics, a JAMA Network publication.

While infant bed sharing is a common practice in many countries, strong associations between the practice and sudden infant death syndrome have been established, according to the study background. The American Academy of Pediatrics recommends that infants share a room with their parents but not a bed for sleeping to prevent sleep-related infant deaths.

The study by Eve R. Colson, M.D., of the Yale University School of Medicine, New Haven, Conn., and colleagues included 18,986 participants in the National Infant Sleep Position study, which was conducted through annual telephone surveys in 48 states. More than 84 percent of the survey respondents were the mothers of infants, while almost half of the caregivers were 30 years or older, had at least a college education and had a yearly income of at least $50,000. More than 80 percent of the participants were white.

Of survey participants, 11.2 percent reported infant bed sharing as a usual practice; the proportion of infants bed sharing increased from 6.5 percent in 1993 to 13.5 percent in 2010. Bed sharing increased among black and Hispanic families throughout the study period. Bed sharing increased among white families in the first study period (1993 to 2000), but not more recently (2001 to 2010), according to the study results.

The percentage of black infants usually sharing a bed increased from 21.2 percent in 1993 to 38.7 percent in 2010; the increase for Hispanic infants was 12.5 percent in 1993 to 20.5 percent in 2010. White infants usually sharing a bed increased from 4.9 percent in 1993 to 9.1 percent in 2010, the study findings indicate.

"We found that black infants, who are at highest risk of sudden infant death syndrome and accidental suffocation and strangulation in bed, share a bed most often. Compared with white infants, black infants are 3.5 times more likely to share a bed," the authors write.

Other factors associated with an infant usually sharing a bed during the study period included a household income less than $50,000 compared to more than $50,000; living in the West or the South compared with the Midwest; infants younger than 15 weeks compared with 16 weeks or older; and being born prematurely compared with full-term.

"The factors associated with infant bed sharing may be useful in evaluating the impact of a broad intervention to change behavior," the study concludes. (JAMA Pediatr.

Editorial: Bed Sharing Per Se is not Dangerous

In an editorial, Abraham B. Bergman, M.D., of the Harborview Medical Center, Seattle, writes: "Colson and colleagues report that from 1993 through 2010, the overall trend for U.S. caregivers to share a bed (also known as cosleeping) with their infants has significantly increased, especially among black families. Because of their belief that bed sharing increases infant mortality, the authors call for increased efforts by pediatricians to discourage the practice. I find the report disquieting because evidence linking bed sharing per se to the increased risk for infant death is lacking."

"The campaign against bed sharing stems from a recommendation of the American Academy of Pediatrics (AAP)," Bergman continues.

"Equal time in counseling should be given to the benefits to bed sharing, such as more sleep for the parent, easier breastfeeding when the infant is nearby, ease of pacifier reinsertion, and the intangible satisfaction of skin-to-skin contact. In its admonition against bed sharing, the AAP has overreached," Bergman concludes. (JAMA Pediatr. Published online September 30, 2013. doi:10.1001/jamapediatrics.2013.2569.

Study examines adverse neonatal outcomes associated with early-term birth

2013-10-01
Early-term births (37 to 38 weeks gestation) are associated with higher neonatal morbidity (illness) and with more neonatal intensive care unit (NICU) or neonatology service admissions than term births (39 to 41 weeks gestation), according to a study by Shaon Sengupta, M.D., M.P.H., now of the Children's Hospital of Philadelphia and formerly of the University at Buffalo, N.Y., and colleagues. Researchers examined data over a three-year period from medical records of 33,488 live births at major hospitals in Erie County, N.Y., 29,741 at a gestational age between 37 to 41 ...

With increased age comes decreased risk-taking in decision-making

2013-10-01
When faced with uncertain situations, people are less able to make decisions as they age, according to a new study by researchers at Yale School of Medicine. Published in the Sept. 30 Proceedings of the National Academy of Sciences, the study also found that older people are more risk-averse than their midlife counterparts when choosing between possible gains, but more risk-seeking when choosing between losses. Scientists have long-observed that cognitive function improves throughout adolescence, peaks in adulthood, and declines with age, but behavioral changes in decision-making ...

New research links individual animal behavior with social spacing

2013-10-01
The joint study by Luca Giuggioli and Jonathan Potts from the University of Bristol, and Daniel Rubenstein and Simon Levin from Princeton University shows that animals deposit marks wherever they go to show their presence, and retreat from marks left by a member of the same species more quickly if the encountered mark is recent. The study published today [30 September] in the Proceedings of the National Academy of Sciences (PNAS) has important implications for how epidemic disease spreads and animal sociality. Lead author, Dr Luca Giuggioli of Bristol's Department ...

International 'war' on illegal drugs is failing to curb supply

2013-10-01
Since 1990, the street price of illegal drugs has fallen in real terms while the purity/potency of what's on offer has generally increased, both of which are indicators of availability. The United Nations recently estimated that the illicit drug trade is worth at least US $350 billion every year. And needle sharing is one of the key drivers of blood borne infections, including HIV. The drug trade is also linked to high rates of violence. Over the past several decades most national drug control strategies have focused on law enforcement to curb supply, despite calls ...

Plentiful mid-life stress linked to heightened risk of dementia in late life

2013-10-01
The response to common life events may trigger long lasting physiological changes in the brain, say the authors. They base their findings on 800 Swedish women whose mental health and wellbeing was formally tracked over a period of almost 40 years as part of the larger Prospective Population Study of Women in Gothenburg, Sweden, which started in 1968. The women, who were all born in 1914, 1918, 1922 and 1930, underwent a battery of neuropsychiatric tests and examinations in 1968, when they were in their late 30s, mid 40s, and 50s, and then again in 1974, 1980, 1992, ...

Autistic kids have poorer sleep quality than their peers right up to their teens

2013-10-01
Total sleep duration is shorter and punctuated by more frequent waking at night, the research shows. Poor quality sleep may affect daytime learning and behaviour, say the authors. Disrupted sleep patterns have been linked to autism before, but the quality of the evidence accumulated to date has often been compromised by small sample size, lack of agreed definitions, and poor comparability of study participants. The authors of this study instead base their findings on long term data derived from the Avon Longitudinal Study of Parents and Children (ALSPAC), which has ...

Skin receptors convey sensation of texture through vibrations

2013-10-01
New research shows that humans distinguish the difference between fine textures, such as silk or satin, through vibrations, which are picked up by two separate sets of nerve receptors in the skin and relayed to the brain. Previous research has shown that coarse textures, such as Braille dot patterns, are encoded by receptors that are densely packed into the primate fingertip. The spatial layout of responses of these receptors corresponds to the spatial layout of surface features of a texture. However, most natural textures are too fine to be perceived in this manner. ...

Better protein creation may be secret of longevity for the world's longest-living rodent

2013-10-01
Naked mole rats have what any animal would want. They live long lives—about 30 years—and stay healthy until the very end. Now biologists at the University of Rochester have new insights into the animal's longevity—better-constructed proteins. Proteins are involved in nearly all functions of an animal cell, and consequently, are essential to all organisms. But before proteins can do their job, they must fold into the appropriate shapes that allow them to connect to and interact with other structures in the cell. In a paper published this week in the Proceedings of the ...

Cold, salty and promiscuous -- Gene-shuffling microbes dominate Antarctica's Deep Lake

2013-10-01
Sequestered in Antarctica's Vestfold Hills, Deep Lake became isolated from the ocean 3,500 years ago by the Antarctic continent rising, resulting in a saltwater ecosystem that remains liquid in extreme cold, and providing researchers a unique niche for studying the evolution of the microbes that now thrive under such conditions. Deep Lake's microscopic inhabitants are dominated by haloarchaea, microbes that require high salt concentrations to grow and are naturally adapted to conditions – at minus 20°C – that would prove lethally cold to other organisms. In a detailed analysis ...

What works for women doesn't work for men

WINSTON-SALEM, N.C., – Sept. 30, 2013 – Flushed face, sweating, a sudden rush of heat. The hot flash, the bane of menopausal women, also can affect men who are undergoing hormone therapy for prostate cancer. But unlike in women, neither soy protein nor a common antidepressant provides relief for men, according to researchers at Wake Forest Baptist Medical Center. Hot flashes occur in approximately 80 percent of men who are undergoing hormone manipulation as treatment for prostate cancer. Hormone therapy reduces the levels of male hormones, called androgens, to prevent ...
