There's mounting evidence that sitting for long periods can have health risks. However, little is known about how the effects of sitting can be countered by standing occasionally. A team of researchers from the United Kingdom and Australia designed a two-day study involving 22 overweight or obese postmenopausal women with high blood sugar who were at risk for diabetes. On the first day, the women were assigned to one of three groups. One group sat for 7.5 hours straight. The other two sat over a 7.5-hour period, but one group was told to stand in place for five minutes every half-hour, and the other was told to walk for five minutes every half-hour. The second day, all the groups sat for 7.5 hours straight.

On both days, the researchers tested each participant's blood levels of glucose, insulin, fatty acids, and triglycerides—all indicators of metabolism. They found that both walking and standing reduced glucose, insulin, and fatty acids—signs of a higher metabolic rate—in women who either stood or walked compared with those who sat the entire time. Moreover, in the two active groups, some of the beneficial effects persisted into the next day, when everyone sat for the entire session.

Millions of postmenopausal women are taking a bisphosphonate like oral alendronate (Fosamax) or intravenous (IV) zoledronic acid (Reclast) to increase bone density. But because long-term use of these drugs has been associated with an increased risk of bone death in the jaw and unusual thighbone fractures, experts have debated how long women should stay on the drugs to minimize the risk of hip or vertebral fractures without raising their risk for these rare but serious complications.

After considering major randomized controlled clinical trials, a task force of the American Society for Bone and Mineral Research has released guidelines on the optimal duration of bisphosphonate therapy for osteoporosis. The guidelines, published in the January 2016 issue of the Journal of Bone and Mineral Research, recommend reassessing a woman's fracture risk after five years of oral bisphosphonates or three years of IV therapy. They advise that women whose risk is still high should continue to take oral bisphosphonates for up to 10 years or IV therapy for up to six years. However, fracture risk should be reassessed every two to three years during extended therapy.

The U.S. Preventive Services Task Force has recently updated their guidelines on depression screening to include pregnant and postpartum women, which will be a great help to the many new moms who experience mood changes that go beyond the “baby blues.” The updated guidelines offer other benefits, too, that help improve everyone’s access to mental health care — especially those who can’t currently afford it.

If you’re planning an escape from the dreary winter weather, and you’re pregnant or trying to get pregnant, you may want to plan your destination carefully. There’s still a lot we don’t know about Zika virus — which is now widespread in several favorite tropical destinations, such as the Caribbean — and its potential pregnancy-related complications. Until we know more, it’s better to be safe and follow the precautions we’ve listed here.

They're convenient and affordable, but they don't replace a relationship with a primary care physician.

Walk into a drugstore, supermarket, or "big box" store these days, and you'll find more than prescriptions, food, and household goods. Many now feature health clinics. They're part of the big trend of making health care more convenient. "Twenty years ago you had to go to an emergency department if you got sick and needed immediate care. Now we have an explosion of options, such as retail health clinics," says Dr. Ateev Mehrotra, a researcher on the topic and an associate professor of health care policy at Harvard Medical School.

The clinics

Retail health clinics began showing up about 15 years ago. Today, there are about 2,000 clinics across the United States, mostly in large retail chain settings. A typical clinic is open from 7 a.m. to 7 p.m., seven days a week, and is staffed by a nurse practitioner or a physician assistant. Clinics offer all kinds of health services—everything from treating minor illness like a cold, pinkeye, or a urinary tract infection to providing physicals, health screenings, lab work, smoking cessation help, and vaccinations.

They're cute, cuddly, and loving, but dogs and cats aren't always appropriate for older adults.

There's a reason dogs are dubbed man's best friend. Dogs—and cats, too—make wonderful companions and provide many emotional and physical benefits. "I'm a believer in the beneficial effects of having a pet, and I'm impressed with the ability of dogs in particular to form bonds with human beings. I think the science is starting to support their special ability to do that," says psychiatrist Dr. Greg Fricchione, director of the Harvard-affiliated Benson-Henry Institute for Mind Body Medicine. However, there are a number of considerations to mull over before adding a pet to your household.

Benefits

The most obvious benefits of pet ownership are love and companionship. "We do best medically and emotionally when we feel securely attached to another, because we're mammals and that's the way we've evolved," says Dr. Fricchione. He points out that we feel especially secure with dogs and cats because of the unconditional love they provide. "No matter what you do or say, your dog or cat accepts you and is attached to you," says Dr. Fricchione. Taking care of a dog or a cat can provide a sense of purpose and a feeling of validation when you wake up or come home and there's someone who's happy to see you.

Fostering strong social connections does not come easy for many men, but it is one of the best means to a longer and healthier life.

Social connections are as important to your health as proper diet and exercise. Research has linked social bonding to longer lives, lower incidence of depression and anxiety, and reduced risk of disease.

"Our brains and bodies function best when we are part of a community and maintain close, personal connections," says Dr. William S. Pollack, assistant clinical professor in the Department of Psychiatry at Harvard Medical School.

The annual check-up is important for older men. Here is how to make the most out of your visit.

Men have a long reputation for avoiding check-ups, and that resistance tends not to soften when they are older.

"Many older men put off exams because they fear finding out something is wrong," says Dr. Suzanne Salamon, a geriatrician with Harvard-affiliated Beth Israel Deaconess Medical Center. "Also, many of today's baby boomers don't think they will have medical problems associated with age, so it can difficult for the 'younger older men,' like those in their 60s and early 70s, to see their doctor."

Ask the doctors

Q: I'm expecting and want to have a vaginal delivery, but many of my friends have had cesarean sections lately. Is this a preference, or are there medical reasons to have a cesarean?

A: The health of the mother and baby, the family's personal preferences, and the hospital in which a woman delivers her baby play a role in determining whether she has a cesarean. Common medical reasons for cesareans include fetal malpresentation (when the baby is turned so that its feet or buttocks will come out first), pelvic disproportion (a birth canal that is unusually shaped or too small in relation to the size of the baby), and a past cesarean. A study published in the Journal of the American Medical Association in December 2015 suggests that such commonly cited medical issues may account only partly for high cesarean rates.

These uterine tumors, though usually benign, can cause heavy bleeding, cramps, and pregnancy complications. But there are several good options for treatment.

Fibroids—smooth muscle tumors of the uterus—are common, affecting as many as 75% of women. They are rarely cancerous, and they cause symptoms in only about 20% of the women who have them. However, if you're one of those with symptoms like heavy menstrual bleeding, bad cramps, pelvic pressure, constipation, or frequent urination, you know how fibroids can disrupt your life. Even if they don't cause symptoms, they may grow into the uterine cavity, potentially complicating a pregnancy and raising the risk of miscarriage.

"Managing uterine fibroids depends on several factors, such as a woman's symptoms, whether or not she wants to have children, her age, and her personal preferences," says Dr. Hye-Chun Hur, director of the Division of Minimally Invasive Gynecologic Surgery at Harvard-affiliated Beth Israel Deaconess Medical Center and associate medical editor of Harvard Women's Health Watch.
