A small study found that babies conceived using assisted reproductive technology (ART) may be more likely to have high blood pressure as teenagers than those conceived naturally.

Close to 2% of babies born in the United States are conceived using ART, most commonly by in vitro fertilization, in which sperm and egg are mixed in a lab dish. In 2012, researchers found that healthy kids born via ART were more likely than their peers to have signs of premature aging of their blood vessels.

Q. The Harvard Health Letter has often said that it is generally healthy for women to have one alcoholic drink per day. Yet I hear a recent study showed no benefit. What's the truth?

A. Before answering your question, let's define "one drink": it's 12 ounces of beer, 5 ounces of wine, or 1.5 ounces of hard liquor. And it means having one drink each day of the week, not having seven drinks on Saturday night, sleeping it off Sunday, and begging off until next Saturday night. Now, despite the recent study, we stick with what we've said, which reflects the research of outstanding nutrition scientists at Harvard and elsewhere.

Older women: Take note of two new screening guidelines. One is for cervical cancer screening. Recommendations from the U.S. Preventive Services Task Force, published online Aug. 21, 2018, by the Journal of the American Medical Association, suggest that many women ages 30 to 65 can now approach cervical cancer screening in several ways: they can get a cervical cytology (Pap) test every three years; a test for human papillomavirus (which causes most cervical cancer cases) every five years; or they can get a combination of both tests every five years. If you're older than 65, the USPSTF recommends against screening unless you haven't had adequate tests before or you're at high risk for cervical cancer. The other screening guidelines are for urinary incontinence. They come from the Women's Preventive Services Initiative and were published online Aug. 14, 2018, by Annals of Internal Medicine. The guidelines recommend that women get screened for incontinence yearly, regardless of age. "I completely agree with brief annual screening for urinary incontinence for women. A simple question can be used to screen for it, such as, 'Do you have any bothersome urinary incontinence or urinary leaking during the day or night?' If the incontinence is treated early, in some cases, it will not progress and the patient will be able to avoid more invasive, costly, risky, or time-consuming treatment options," says Dr. May Wakamatsu, vice chair of gynecology services at Harvard-affiliated Massachusetts General Hospital.

Running, jumping, and other weight-bearing exercises stimulate your bones and make them stronger.

If you've gone through menopause, your bones probably aren't as strong as they used to be.

"Around the time of menopause, there is accelerated bone loss in women as the ovaries stop producing estrogen," says Dr. Meryl S. LeBoff, professor of medicine at Harvard Medical School. This bone loss usually continues as you age, leading in some cases to either of two conditions: osteoporosis (a significant loss of bone density), or the less severe osteopenia (low bone mass). Together, these conditions affect 43.4 million Americans. Either can cause the bones to become brittle and break easily.

A new study published online August 10 by the Journal of the American Medical Association shows that women with ductal carcinoma in situ (DCIS) — cancerous changes to the cells inside the milk ducts of the breast — may have better results if they have radiation in addition to a lumpectomy.

Researchers examined 15-year outcomes in 140,000 women with DCIS who underwent either lumpectomy or mastectomy alone, or both lumpectomy and radiation. Women who had radiation in addition to lumpectomy procedures were slightly less likely to die from breast cancer than women who had either a lumpectomy or mastectomy procedure alone.

Ounce for ounce, bone bears as much weight as reinforced concrete. However, unlike reinforced concrete, bone is a living tissue. It serves as a repository of minerals for the rest of the body to use, continuously lending them out and replacing them. Bone also gets stronger when "stressed" by physical activity, and can repair itself when injured.

The building and tearing down of bone tissue is called remodeling. This process happens continuously throughout your entire life. At first, your body rebuilds more bone than it demolishes. Typically, a person reaches peak bone mass around the age of 30. Among women, bone mass usually remains steady for the next 20 years or so until the onset of menopause, when bone is lost much more quickly than it is replaced. When bone loss is significant, the result is osteoporosis (which means "porous bone"). Bone loss generally starts later for men — typically in the late 50s — and progresses more slowly than in women. But men can also get osteoporosis.
