THURSDAY, May 24 (HealthDay News) -- Japanese-American men who don't eat a diet rich in vitamin D have an increased risk of stroke later in life, according to a new, long-term study.

The study included nearly 7,400 Japanese-American men living in Hawaii. They were between the ages of 45 and 68 in the mid- to late-1960s, when they were first examined and interviewed about their eating habits.

During 34 years of follow-up, 960 of the men suffered strokes. Compared to those with the highest levels of vitamin D in their diet, men who took in the least dietary vitamin D had a 22 percent higher risk of stroke and a 27 percent higher risk of ischemic (blood-clot-related) stroke. No difference existed for hemorrhagic (bleeding) stroke, however.

The study appeared May 24 in the journal Stroke.

"Our study confirms that eating foods rich in vitamin D might be beneficial for stroke prevention," study author Dr. Gotaro Kojima, a geriatric medicine fellow at the John A. Burns School of Medicine at the University of Hawaii in Honolulu, said in a journal news release.

Kojima said, however, it's unclear whether the study findings could be applied to women or to different ethnic groups.

Sunlight generally is the primary source of vitamin D, but synthesizing vitamin D from the sun becomes more difficult as people age, Kojima said, meaning older people need to eat more foods rich in vitamin D or take supplements. Fortified milk, breakfast cereals, fatty fish and egg yolks all are good sources of vitamin D.

Infidelity in men may be associated with higher risk of cardiovascular events

The authors of this study from Italy performed an extensive Medline search for "infidelity," "extramarital", "infidelity" and "men".

Infidelity in men is how common?

As expected, the results were variable. Some surveys reported that 1.5-4% of married men had extramarital coitus in any given year, 23.2% of other men who have cheated during their current relationship.

Lifetime prevalence of infidelity was between 15% and 50%.

What are the factors related to infidelity?

Men with more extramarital affairs have often a dysfunctional primary relationship.

Authorship and conflict within the family are associated with a higher risk of having an affair.

Unfaithful men display a higher testicular volume androgenization, increased sexual desire and sexual functioning better.

What are the clinical implications of infidelity in men?

Some studies have suggested that having an affair could have a negative impact on cardiac morbidity and mortality. Infidelity in men seems to be associated with a higher risk of cardiovascular events.
