What is Your Health Horoscope?

What is Your Health Horoscope?

By Sean Kenniff, MD

  The secret to living a longer and healthier life may not be as simple as eating a balanced diet and getting a lot of exercise. Recent research suggests your ‘health horoscope’ may be increasing or decreasing your odds of developing diseases. First-born children in large families tend to live the longest. In fact first-born children are 2-3 times more likely to reach age 100 than later-born children. Babies born to younger mothers may also enjoy an increased lifespan according to some reports. People living in rural environments tend to live longer than those living in urban and suburban environments. Some studies have even concluded that you are more likely to die near your birthday, or in the three months following it. Stress is believed to play a role. So what does your birthday say about your health risks?

JANUARY

Children conceived in the spring and summer months, and born from January through March may be at increased risk of birth defects according to a large U.S. study. In-utero exposure to pesticide residues during the warmer months may be playing a role.

A 2004 study published in the journal Neurology found people born during January and February are at the highest risk for developing malignant and benign brain tumors. Those born in the summer months of July and August had the lowest risk.

Women born in the first 6-months of the year might have a higher risk of developing breast cancer according to a report published in Oncology Reports.

People born in January and December have the highest lifetime risk of developing Alzheimer’s disease, epilepsy and narcolepsy. Those born during the spring and summer months are less likely to develop these conditions.

Lower air temperature at birth has been associated with the development of increased insulin resistance and increased triglycerides as adults. So U.S. babies born during the colder winter months may be at an increased risk of developing coronary artery disease earlier in life.

Studies have shown people born in February and March (late winter to early spring in the northern hemisphere) are more prone to develop schizophrenia. But the difference is small, about a 10% increase compared to the lowest risk months (September and August). It’s been proposed that a lack of sunlight during these months may result in a vitamin-D deficiency. A lack of adequate vitamin-D in a newborn, or a pregnant mother might influence a child’s brain development.

March

Studies have shown people born in February until March (late winter to early spring in the northern hemisphere are more prone to develop schizophrenia. But the difference is small, about a 10% increase compared to the lowest risk months (September and August). It’s been proposed that a lack of sunlight during these months may result in a vitamin-D deficiency. A lack of adequate vitamin-D in a newborn, or a pregnant mother might influence a child’s brain development.

People born in the spring months tend to have the shortest lifespans, about 5-months shorter than those born during the autumn months according to a study of 15-million U.S. death certificates.

Women born in the first 6-months of the year might have a higher risk of developing breast cancer according to a report published in Oncology Reports.

Italian researchers claim that women born in March are more likely to go through menopause earlier than women born in the fall months. On average, women in the study who were born in March went through menopause at age 48-years and 9-months, whereas women born in October went through menopause 18-months later (age 50-years and 3-months).

Children conceived in the spring and summer months, and born from January through March may be at increased risk of birth defects according to a large U.S. study. In-utero exposure to pesticide residues during the warmer months may be playing a role.

April

A study published in the British Journal of Psychiatry examined data from nearly 27-thousand suicides over a 22-year period and found people born during April, May, and June are 17% more likely to commit suicide. The increased risk was higher for women (29.6%) compared to men (13.7%). It’s possible that seasonal hormone fluctuations in pregnant women may influence the developing fetal brain.

A U.S. team of researchers found children conceived during the spring and summer months are more likely to be born with birth defects including cleft lip and palate, club foot, Down Syndrome, and spina bifida. Increased exposure to pesticides may be playing a role the researchers said.

Children born in May and November are the least likely to develop Acute Lymphoblastic Leukemia (ALL).

Breast Cancer Risk: Does Size Matter?

 Large-breasted women are often concerned they could be facing an increased risk of breast cancer. Conversely, smaller-breasted women often assume they have less of a risk. But studies have shown there is no clear association between breast size and the risk of developing breast cancer. 

 The breast is primarily made up of two types of tissue: glandular tissue like the milk ducts and the mammary glands, and stromal tissue like fat and fibrous tissue. Breast cancer tumors usually arise from the glandular tissues. And while larger breasts can contain more glandular tissue than smaller breasts, breast size is largely a reflection of the amount of fatty tissue in the breast. Though some studies have shown a weak correlation between large breasts and breast cancer, most studies have not. 

 However there is some evidence that breast density could be a risk factor for breast cancer. Denser breasts have relatively less fatty tissue and more glandular tissues. While it is normal for young women to have dense breasts, many studies suggest women with increased breast density after menopause could be at a slightly increased risk of developing breast cancer. 

 It’s important to note that overweight and obese women often have larger breasts, and they also have a higher risk of breast cancer. But this is probably not related to increased breast size, but rather to the excess estrogen produced by fat cells in the body. -Sean Kenniff, MD
