People who have kids live longer than those who remain childless, an academic study has suggested. Researchers believe it is because adults' immune systems are "refreshed" when toddlers go to nursery and start picking up infections. During the course of someone's life, their immune system can become weaker.
You may feel that your kids are sending you to an early grave, but parents live longer than childless people, especially once they reach 80, found a study in Sweden — and the longevity edge becomes greater as parents get older.
The researchers examined several different measures that represent how a person's body is aging and found that people who had few births -- or many -- seemed to have aged quicker than those who had given birth three or four times. However, these effects were found only after a person had gone through menopause.
Women who give birth at an older age live slightly longer than those who do so earlier. Those who are able to become pregnant and give birth at a later point in their lives probably have good overall health, which also supports an older life expectancy.
Apart from all the joys that girls bring into this world, turns out they can also add some precious years to their father's life, says a new study. According to this study, dads with daughters tend to live longer than those who do not have any daughter.
Women whose mothers live up to the age of 90 are more likely to have increased lifespan, without suffering from any serious illnesses like cancer, diabetes, or heart disease, a study has found.
Marriage and longevity
Married men and married women live, on average, two years longer than their unmarried counterparts. One reason for this longevity benefit is the influence of marital partners on healthy behaviors.
Another possible factor in play in the slowing down of aging observed in the study is the increased levels of the hormone estradiol during pregnancy. Estradiol is an antioxidant that helps protect cells from the wear caused by natural cell processes. Estradiol is also known to increase telomerase activity.
Scientists in the US made the discovery after reconstructing the family histories of 198 centenarians born between 1875 and 1899. They found that first-born children were 1.7 times more likely than their siblings to live to 100.
This analysis found that the protective effect of being first-born is driven mostly by the young maternal age at person's birth (being born to a mother younger than 25 years). Being born to a young mother is the major predictor of human longevity (OR = 2.03, 95% CI = 1.33–3.11, p = 0.001; see also Fig. 1).
The risks of miscarriage and stillbirth are higher in people who are older than 35. Also, multiple pregnancy is more common when you are older. As the ovaries age, they are more likely to release more than one egg each month. Some fertility treatments also increase the chance of a multiple pregnancy.
By their mid-40s, customarily considered the likely end of childbearing years (though of course there are exceptions), about 1 in 7 (or 14 percent) never did have any kids.
Even with all the understandable talk of “windows of opportunity” and “biological clocks,” there are ways for women over 35 to make motherhood a reality. Infertility treatments can be difficult and expensive, but fertility specialists can talk with you about options. Age is less of a limitation than it used to be.
The Good News
Not having children also comes with significant positive health benefits. A 116-year study by the American Journal of Human Biology found the following trends. Longer lifespan. Women with children lost an incredible 95 weeks of life per child carried.
A 2021 survey by Pew found that the number of non-parents aged 18 to 49 who said they were not too likely or not at all likely to have children was 44%, up seven points compared to 2018. Among these people, 56% said they simply did not want to have children.
The least common birthdays in the U.S. interestingly all hover around major holidays. December 25 (Christmas Day) is the least common birthday, while January 1 (New Year's Day) is the second least common.
First, which month has the least birthdays? The data comes from the Centers for Disease Control and Prevention and the Social Security Administration. The rarest month to be born in is February, making Aquarius the rarest zodiac sign. February is the shortest month of the year, even with a leap year.
Differences in Adult Lifespan by Month of Birth. We find a similar relationship between month of birth and lifespan in both of our Northern Hemisphere countries. Adults born in autumn (October–December) live longer than those born in spring (April–June).
Although most men are able to have children well into their 50s and beyond, it becomes gradually more difficult after the age of 40 . There are many reasons for this, including: Sperm quality tends to decrease with age.
Back-to-back pregnancies can deplete essential nutrients, making mothers at higher risk for anemia and other complications such as uterine rupture, and also putting their babies at risk of low birth weight and preterm birth.
Although there is no standardized definition of AMA, one common definition is of maternal age above 35. Beyond that, maternal age above 40 is considered very advanced maternal age (VAMA), and above 45, very late maternal age\extremely advanced maternal age (EAMA).
Hu found that reported happiness was higher overall among married people than unmarried people. By gender, 56.2 percent of married men said they were “very happy,” compared with only 39.4 percent of unmarried men who said so.
Being Single Can Be Healthy
Research shows that people who are single, especially men, are living longer than ever before. In the past, men who were never married typically had the lowest life expectancy, but now the never married men are closing in on their currently married counterparts.
The longest marriage recorded (although not officially recognized) is a granite wedding anniversary (90 years) between Karam and Kartari Chand, who both lived in the United Kingdom, but were married in India.
