These findings are troubling and suggest “a critical need for COVID-19 behavioral change interventions targeted at older men,” the study’s authors conclude.
Men expressed elevated levels of anxiety and stress when they were the sole source of their family’s income. Those distress levels declined, however, when wives were working — but only when the women’s earnings did not exceed 40 percent of household income.
Aging not only affects a man’s fertility, the study found, but becoming a father late in life also increases the risk that the mother of the child will have complications during pregnancy and that the child will have health problems.
“For most men, it probably doesn’t make a lot of difference,” said Jorge Chavarro, the study’s senior author. “The men who are most likely to benefit are the men who are on the border — who have relatively low sperm count.”
Among men with cardiometabolic disease, those who were experiencing job strain were 68 percent more likely to die over the course of the study than those without job strain.
“This evidence indicates that physical activity guidelines should differentiate between occupational and leisure time physical activity,” the study’s authors conclude.
For men aged 70 and older, the recommendation is that they should not be routinely screened because the potential benefits for men in that age group do not outweigh the potential harms.
The study suggests that it’s the total volume of physical activity, not necessarily the length of each exercise session, that matters — at least for older men.
The researchers also found no statistically significant differences in sexual or prostate problems between high- and low-intensity cyclists.
About 9 percent of all newborns in the United States now have dads older than 40, and almost 1 percent have dads over the age of 50.
For the new study, researchers conducted a meta-analysis of data collected from 185 previous studies published between the years 1973 and 2011.
With the results of the new studies, “the hopes for testosterone-led rejuvenation for older men are dimmed and disappointed if not yet finally dashed,” writes endocrinologist David Handelsman.
Evidence linking testosterone drugs to an increase risk of heart attacks, blood clots and prostate cancer is often minimized. As a result, these drugs are being overprescribed to older men, the report points out.
Men put on extra pounds — as measured by an increase in body mass index (BMI) — during the first few years of fatherhood, whether or not they live with their child, the study found.
“Last week’s heart-disease study is far from another reason to want to be taller,” The Atlantic’s Dr. James Hamblin concludes.
Testosterone drugs are supposed to be used only by men whose low testosterone levels are due to hypogonadism — a relatively rare medical condition.
Low-T testing at age 40? There is no scientific evidence to support this recommendation; it’s purely a marketing ploy.
The disorders linked to phthalates and other chemicals include everything from compromised sperm quality to congenital malformations of the testes and urethra.
Direct-to-consumer marketing of drugs is prohibited in the U.K. — a likely key factor behind the countries’ differences, say researchers.
Low testosterone is “in large part an invented condition,” and commercials for “low-T” gels, patches and other products are simply playing on older men’s fears about aging.
