Early Warning Blood pressure is higher in young men who were born prematurely, finds a report in Circulation: Journal of the American Heart Association. The risk, at least for men, eclipsed that long associated with being small at birth.
The findings come from a study of more than 300,000 Swedish men born between 1973 and 1981. All had blood pressure readings recorded at age 20 when they were conscripted for military service.
The risk of high systolic blood pressure (the top reading) grew from 25 percent for moderately preterm birth (33 to 36 weeks in the womb) to 93 percent for extremely preterm (24 to 28 weeks in the womb). More research is needed to know if the findings hold for women.
Just Eat It Girls who get calcium from food appear to gain more bone mass than those who get it from supplements, finds a study in the American Journal of Clinical Nutrition. But those who get enough calcium in their diet derive no added benefit from the mineral supplements.
The two-year study involved 195 healthy girls, ages 10 to 12, whose calcium intake was below the 900 mg a day recommended by the National Nutrition Council. Participants received either low-fat cheese (1,000 mg of calcium), 1,000 mg calcium tablets, the same tablets plus 200 IU vitamin D tablets, or placebo. The cheese group showed the most beneficial effects in bone mass.
But when researchers compared individual growth speed, no intervention was found more beneficial than another. The authors concluded that was because most subjects already received adequate calcium in food.
