Many factors are contributing to the rise of early onset puberty in girls. Learn what they are below and how you can support your daughter. The number of girls experiencing early puberty has increased dramatically over the last few years and continues to grow. More and more girls in the U.S. are starting to show signs of development before the age of 8. Recent studies show that up to 10 percent of Caucasian girls and 23 percent of African American girls are showing signs of puberty by age 7. What’s Contributing to Early Puberty in Girls? Determining the exact cause is difficult. But experts agree that several factors may be contributing to these growing numbers. Increasing rates of childhood overweight and obesity. Excess body fat alters the levels of hormones responsible for the acceleration of pubertal timing. Physical inactivity may decrease melatonin levels, which can also trigger pubertal development. Increased animal protein intake. Higher total protein, animal protein and meat intake in children ages 3 to 7 have been associated with earlier onset of menstruation. High protein intake elevates IGF-1 levels and promotes growth, which could accelerate the onset of puberty. Poor diet. Children with lower-nutrient diets tend to enter puberty earlier. A diet rich in processed foods and meats, dairy, and fast food is disruptive to normal physical development. Exposure to EDCs (endocrine-disrupting chemicals). EDCs are synthetic chemicals found in plastics, pesticides, fuels and other industrial chemicals that inhibit or alter the action of natural hormones. Because EDCs accumulate in the fatty tissues of animals, animal foods contain higher levels of these chemicals than plant foods. Exposure to BPA (bisphenol A). BPA is an industrial petrochemical found in a variety of products including plastics, tin-can linings and even cash register receipts. Because it acts as a synthetic estrogen it may speed up pubertal development. Soy products. Soy contain isoflavones which are converted to phytoestregens in the body, and are similar to the hormone estrogen, Dr. Chelsea Wicks says. “Soy consumed from natural food sources is likely safe and will not cause abnormal hormones levels. However, when consumed in large amounts, such as with soy supplements or in more processed foods, there have been links to chronic medical problems due to elevated estrogen levels. I feel a good answer to this is to continue working on eating fresh foods and trying to avoid the processed, packaged foods as this will be best for overall general nutrition as well,” she adds. What You Can Do While some genetic factors play a role in the early onset of puberty, parents can help lessen environmental causes of the condition. Encourage and help your child to maintain a healthy weight with proper nutrition and exercise. Avoid exposure to hormones such as estrogen and testosterone that may be found in hair products, medications and nutritional supplements. Avoid exposure to EDCs and BPA. Offer your child a diet centered around whole plant foods rather than animal foods, which will help keep protein intake within a safe range and reduce consumption of EDCs. Create a supportive environment for your daughter. Avoid commenting on her appearance and instead focus on her achievements, academic successes or artistic talents. Speak to her openly and honestly about the physical changes she’s experiencing — that although these changes are normal, she’s simply developing early — and that ultimately her peers will undergo the same changes. Encourage your daughter to continue participating in social activities and pursuing her interests, and reassure her you are always open to discuss any questions or worries. If you are concerned that your child may be going through these changes before expected, speak with your pediatrician. Sources: Early Puberty: Causes and Consequences When Is Puberty Too Early?

Humidifiers are a great way to moisturize the air in your home as outside temperatures plummet, helping with chapped skin, allergies and cold and flu symptoms in children and adults. But without regular upkeep, humidifiers can breed dangerous mold and bacteria and do more harm than good. We’ve gathered some tips for keeping your humidifier — and your home — clean and bacteria-free. Dirty humidifier tanks can quickly breed bacteria and mold. This can be a problem for healthy people, but especially problematic for people with asthma and allergies when the contaminated mist or steam is released into the air. Here are some top ways to keep your humidifier humming and prevent unintended bacterial growth. Use distilled or demineralized water. Tap water contains mineral-creating deposits inside your humidifier that promote bacterial growth. These minerals often appear as white dust on your furniture. You may also breathe in some of these minerals. Distilled or demineralized water has a much lower mineral content compared with tap water. Instead of distilled water, you can also use demineralization cartridges or filters in your humidifier if they’re recommended by the manufacturer. Change the water often. Avoid letting water sit in the tank for long periods of time. This causes mineral deposits to collect on the bottom and sides of the tank. The longer the water sits, the more deposits will collect and the harder they’ll be to remove. Keep the area around the humidifier dry. If the area around your humidifier becomes too damp, turn it down. Surrounding the humidifier with dampness can lead to mold and bacterial growth. Change the filter in your central air conditioning and heating system regularly. Your humidifier is circulating more water in the existing air in your home. Optimize the cleanliness of your humidifier by ensuring your general air quality is clean. Clean the humidifier regularly. When the humidifier is in heavy use during the winter or when a family member has a cold, clean it weekly with a simple vinegar or hydrogen peroxide rinse. Do a deep monthly clean of the tank, base and filter (or per your manufacturer’s instructions). Replace the humidifier when necessary. Old humidifiers may start to break down over time. The worn-out parts will be more prone to hosting bacterial growth. If you’ve had your humidifier for five years, you might want to consider replacing it. Humidifiers can build up difficult mineral deposits, which are impossible to remove and encourage bacterial growth. Store the humidifier properly. Before putting your humidifier in storage, clean it thoroughly. Throw away any temporary parts (such as used filters or water cartridges) and make sure it is completely dry. Rinse or clean it again before using it the next time. Order any new filters or cartridges you’ll need when you use it again and store them with the humidifier. With proper maintenance, a humidifier can be an affordable at-home method for fighting colds and flu, and for making indoor winter air more hospitable. If you have a humidifier built into your central heating and cooling system, consult the instruction manual or ask your heating and cooling specialist about proper upkeep.

Every 40 seconds someone in the U.S. has a stroke, but 80 percent of all strokes are preventable. That’s why knowing the signs and symptoms and what to do is so important. With May being National Stroke Month, we asked Sadie Wangler, program manager with Renown Institute for Neurosciences, to explain more. We can prevent strokes by changing our lifestyle behaviors that increase our risk. Knowing the symptoms and being prepared to B.E. F.A.S.T. are key as well. We asked Sadie Wangler, program manager for the Renown Institute for Neurosciences, what everyone person should know about stroke. What is a stroke? A stroke can be caused by a blood clot within an artery in the brain or a blood vessel. The clot can burst due to blockage and this causes blood flow to the brain to be cut off. Without the proper bloodflow and oxygen getting to the brain, the brain’s tissue begins to die. How to spot symptoms of a stroke? The easiest thing is to remember the word “B.E.F.A.S.T.” B – Loss of balance: Ask the person to walk 5-10 feet, with light assistance, and ask if they felt dizzy or off balance. E – Double Vision or blurred vision: Ask the person if their vision has changed in any way. F – Look for face drooping: Ask the person to smile and see if one side of their face droops. A – Arm weakness: Ask the person to raise both arms. Does one arm drift downward? S – Speech difficulty: Ask the person to repeat something. Is their speech slurred or strange? T – Time to call 911: Time matters – so don’t wait to call an ambulance if you or a loved one is experiencing these symptoms. You can also watch for sudden numbness or weakness in the face, arm or leg, especially on just one side of the body. Look for any confusion — if they’re having trouble speaking or difficulty understanding others talk — and if they have trouble seeing in one or both eyes, trouble walking, dizziness, loss of balance, or sudden and unexplained severe headache. The signs of stroke happen suddenly and a lot of people may deny their symptoms, thinking they’re overreacting. But it’s critical to act quickly and get medical attention right away — when it comes to stroke and saving your brain, minutes matter. What should you do if you think you or someone you love is having a stroke? In addition to seeking help right away, it’s best to call 911 and get an ambulance. A lot of people make the mistake of driving themselves to the hospital or have someone else drive them, and this can be dangerous for a number of reasons. First of all, it can put you, your loved ones and others on the road in danger. Second, going to the hospital on your own can take more time than calling an ambulance, and when it comes to stroke, every minute of medical care counts. So it’s important to call 911 and get treatment immediately. What can you do to prevent stroke? A stroke can happen to anyone, but certain risk factors can increase your risk. There are some risk factors you can’t control: your age, family history, race and gender. Stroke risk is higher for women and people over the age of 55. Fortunately, there are some risk factors you can control, such as high blood pressure, smoking, artery or heart disease, high cholesterol, as well as obesity, poor diet and lack of exercise. A lifestyle focused on healthy diet and regular exercise can greatly reduce your risk for stroke. Quitting smoking and watching your alcohol intake can help too.

With a family history of breast and other cancer, Aime′ Landaburu isn’t missing a single health screening. She recently had her first mammogram as well as a whole breast ultrasound, which detects 41 percent more cancers and reduces the number of false-positive results. Like many people, Aime′ Landaburu is busy juggling parenthood and a career. It would be easy to put health screenings on the back burner, but with a grandmother who has survived breast cancer three times and a grandmother who had ovarian cancer, Landaburu is addressing her family health history head-on. “I decided at 35 that I needed to get my screenings done because I have my family history of both grandmothers having had cancer,” Landaburu says. “In addition to the mammogram, I was really interested in doing the whole breast ultrasound. It is the same price as getting my hair done and it’s potentially something that could save my life.” Landaburu says the procedures were painless. “It was really comfortable, and the techs were all so nice and kind and gentle and explained things along the way.” Breast Screening Technology Provides Greater Insight George Krakora, MD, lead radiologist for Renown’s Breast Health Center, says the new 3D imaging for mammograms is picking up subtle cancers that would not have been seen with the previous 2D imaging. “It’s an additional tool that helps find those subtle cancers that may be missed in dense breasts,” Dr. Krakora says. With the whole breast ultrasound, the tech screens for masses — which are often obscured on the mammogram X-ray. Studies show it detects an additional 2 to 3 cancers per 1,000 women that would not have been detected with routine mammography. “Aime′ was noted to have heterogeneous dense breast tissue. That puts her at a little higher risk for cancer and also limits the sensitivity of mammography,” Dr. Krakora says. Multiple Ways to Screen for Breast Cancer However, Dr. Krakora notes, breast ultrasound is not a substitute for mammography, which can detect calcifications that can represent the earliest forms of cancer.” Surprisingly to Landaburu, her results came in just three days. “It’s so important to know what’s going on in your body. I was really nervous when I first got the paperwork, but ultimately it was negative, “ Landaburu says. “I’m thankful it was good and I have a baseline for the future.” Landaburu also advises other young women with a history of breast cancer to proactively communicate. She says it’s important to reach out to women they know who have survived breast cancer. “You have to take the first step and you want to be around for your kids and your family and yourself,” she says. “So utilize your resources, educate yourself and go get screened.” Breast Cancer Screening and Prevention Breast cancer begins when abnormal cells in the breast grow out of control. These cells form tumors that can grow into the surrounding tissue and spread to other parts of the body. Breast cancer occurs mostly in women, but men can also develop breast cancer.
