SIDS: Maternal Smoking Doubles Risk

Smoking increases the risk of sudden infant death syndrome, or SIDS, a European analysis shows.

The researchers compared 745 SIDS cases with more than 2,400 live babies for comparison and concluded that just under half of all deaths were attributable to infants sleeping on their stomachs or sides. Roughly 16% of SIDS deaths were linked to bed sharing, but for unknown reasons, bed sharing was particularly risky when the mother smoked. The risk was very small when mothers did not smoke during pregnancy, the researchers say.

Maternal smoking alone was associated with a doubling in SIDS risk. The risk was 17 times greater, however, for babies who bed shared and had mothers who smoked. The findings are reported in the Jan. 17 issue of The Lancet.

"The safest thing to do is to put the baby to bed on his back with no bedcovers in the same room with parents who don't smoke," London School of Hygiene and Tropical Medicine epidemiologist Robert G. Carpenter, PhD, tells WebMD.

Colic: Smoking Makes Babies Irritable, Too

Exposure to tobacco smoke may increase babies' risk of colic, according to a review of more than 30 studies on the topic.

Colic often starts a few weeks after birth, peaking at about 5 to 8 weeks of age. It usually goes away by 4 months of age. Babies' symptoms include irritability, inconsolable crying, red face, clenched fists, drawn-up legs, and screaming.

Colic affects an estimated 5%-28% of babies born in Western countries. Its causes have been attributed to everything from exposure to cow's milk proteins to feeding difficulties to maternal depression or anxiety.

Tobacco smoke appears to raise levels of a gut hormone called motilin in the blood and intestines. Motilin increases the contractions of the stomach and intestines, increasing the movement of food through the gut. "Higher-than-average motilin levels are linked to elevated risks of infantile colic," the researchers write in the October issue of the journal Pediatrics.

An Increased Risk of Impotence

Guys concerned about their performance in the bedroom should stop lighting up, suggests a study that linked smoking to a man's ability to get an erection. The study of nearly 5,000 Chinese men showed that men who smoked more than a pack a day were 60% more likely to suffer erectile dysfunction, compared with men who never smoked cigarettes.
