Muslims have least sex outside marriage: Study

Of all the world's major religious groups, Muslims are the least likely to have sex outside of marriage, new research found. And as a country's Muslim population grows, the rate of premarital sex declines for all residents, even non-Muslims, according to the study.

Researchers analyzed the responses of over 620,000 people (ages 15-59) who were interviewed as part of the Demographic and Health Surveys in 31 mostly developing nations from 2000 to 2008. Most countries included in the sample had either a Muslim or Christian majority, except India and Nepal, which have Hindu majorities, and Cambodia which has a Buddhist majority. (The United States was not included in the study.)

They found that, overall, the odds of married Muslims reporting premarital sex are 53 percent lower than for Christians. Hindus are 40 percent less likely to report premarital sex, compared with Christians. Meanwhile, Jews and Buddhists have greater chances of having sex before getting hitched than Christians do, according to the study.image

The researchers believe these results could be linked to Muslims' greater adherence to strict religious tenets that only allow sex within marriage. As many Muslim leaders place heavy importance on fidelity in marriage, it might be no surprise that Muslims also are less likely than Hindus, Christians and Jews to report extramarital sex, as the study found.

What's more, the religious values of a Muslim majority in a country seem to exert a big influence on the wider population's sexual norms. A 1 percent increase in the percentage of Muslims in a nation caused a 2 percent decrease in the likelihood of premarital sex for all citizens, regardless of their religious identity, the study found. (The researchers note that an increase in the Muslim population in a country did not further reduce the odds of premarital sex among just Muslims.)

"All major world religions discourage sex outside of marriage, but they are not all equally effective in shaping behavior," wrote the researchers, led by Amy Adamczyk, an associate professor of sociology at John Jay College of Criminal Justice in New York. Their study was published in the October issue of the American Sociological Review.

The team speculated that in Muslim-majority countries, strict laws on women's mobility and interaction between the sexes might cut down the opportunities for sex outside marriage. But the researchers found no significant relationship between a country's restrictions on women and the odds of premarital and extramarital sex, suggesting religion plays a greater role than those laws in policing sexual behavior.

The same was true for age. Muslims and Hindus are more likely to have an arranged marriage and to marry younger than Christians and Jews. Though the likelihood of premarital sex increased with age, the study found that age was not a significant factor in driving down rates of premarital sex for these religious groups.

"One of the most surprising findings was that religious affiliations have a real influence on people's sexual behaviors," Adamczyk said in a statement. "While a lot of research attention has been given to understanding differences between the major world religions in adherents' attitudes, much less attention has been given to understanding differences based on behaviors."

The researchers considered that social pressure could have caused some respondents being interviewed in the Demographic and Health Surveys (funded by USAID) to lie. But the survey mandates that interviewers be the same gender as the respondent and try to conduct the questionnaire in private. The latter is not always possible and interviewers are instructed to note the presence of others. They are also told to flag inconsistent responses  (For example, if a respondent says she was a virgin at the time of marriage, but her reported age at first intercourse is younger than her age at marriage, that would get flagged.)

California, May 13: A fasting-mimicking diet could be more effective at treating some types of cancer when combined with vitamin C, suggests a new study conducted by the scientists from USC and the IFOM Cancer Institute in Milan.

In studies on mice, researchers found that the combination delayed tumour progression in multiple mouse models of colorectal cancer; in some mice, it caused disease regression. The results were published in the journal Nature Communications.

"For the first time, we have demonstrated how a completely non-toxic intervention can effectively treat an aggressive cancer," said Valter Longo, the study senior author and the director of the USC Longevity Institute at the USC Leonard Davis School of Gerontology and professor of biological sciences at the USC Dornsife College of Letters, Arts and Sciences.

"We have taken two treatments that are studied extensively as interventions to delay ageing-- a fasting-mimicking diet and vitamin C -- and combined them as a powerful treatment for cancer," added Longo.

The researchers said that while fasting remains a challenging option for cancer patients, a safer, more feasible option is a low-calorie, plant-based diet that causes cells to respond as if the body were fasting.

Their findings suggest that a low-toxicity treatment of fasting-mimicking diet plus vitamin C has the potential to replace more toxic treatments.

Results of prior research on the cancer-fighting potential of vitamin C have been mixed. Recent studies, though, are beginning to show some efficacy, especially in combination with chemotherapy.

In this new study, the research team wanted to find out whether a fasting-mimicking diet could enhance the high-dose vitamin C tumour-fighting action by creating an environment that would be unsustainable for cancer cells but still safe for normal cells.

"Our first in vitro experiment showed remarkable effects. When used alone, fasting-mimicking diet or vitamin C alone reduced cancer cell growth and caused a minor increase in cancer cell death. But when used together, they had a dramatic effect, killing almost all cancerous cells," said Longo.

Longo and his colleagues detected this strong effect only in cancer cells that had a mutation that is regarded as one of the most challenging targets in cancer research.

These mutations in the KRAS gene signal the body is resisting most cancer-fighting treatments, and they reduce a patient's survival rate. KRAS mutations occur in approximately a quarter of all human cancers and are estimated to occur in up to half of all colorectal cancers.

The study also provided clues about why previous studies of vitamin C as a potential anticancer therapy showed limited efficacy. By itself, a vitamin C treatment appears to trigger the KRAS-mutated cells to protect cancer cells by increasing levels of ferritin, a protein that binds iron.

But by reducing levels of ferritin, the scientists managed to increase vitamin C's toxicity for the cancer cells. Amid this finding, the scientists also discovered that colorectal cancer patients with high levels of the iron-binding protein have a lower chance of survival.

"In this study, we observed how fasting-mimicking diet cycles are able to increase the effect of pharmacological doses of vitamin C against KRAS-mutated cancers," said Maira Di Tano, a study co-author at the IFOM, FIRC Institute of Molecular Oncology in Milan, Italy.

"This occurs through the regulation of the levels of iron and of the molecular mechanisms involved in oxidative stress. The results particularly pointed to a gene that regulates iron levels: heme-oxygenase-1," added Tano.

The research team's prior studies showed that fasting and a fasting-mimicking diet slow cancer's progression and make chemotherapy more effective in tumour cells while protecting normal cells from chemotherapy-associated side effects. The combination enhances the immune system's anti-tumour response in breast cancer and melanoma mouse models.

The scientists believe cancer will eventually be treated with low-toxicity drugs in a manner similar to how antibiotics are used to treat infections that kill particular bacteria, but which can be substituted by other drugs if the first is not effective.

To move toward that goal, they say they needed to first test two hypotheses: that their non-toxic combination interventions would work in mice, and that it would look promising for human clinical trials.

In this new study, they said that they've demonstrated both. At least five clinical trials, including one at USC on breast cancer and prostate cancer patients, are now investigating the effects of the fasting-mimicking diets in combination with different cancer-fighting drugs.

There is no evidence that the Bacille Calmette-Guerin (BCG) vaccine, which is primarily used against tuberculosis, protects people against infection with the novel coronavirus, the World Health Organization (WHO) said.

The WHO therefore didn't recommend BCG vaccination for the prevention of COVID-19 in the absence of evidence, according to its daily situation report on Monday, Xinhua news agency reported.

"There is experimental evidence from both animal and human studies that the BCG vaccine has non-specific effects on the immune system. These effects have not been well characterized and their clinical relevance remains unknown," WHO stated.

Two clinical trials addressing the question are underway, and WHO will evaluate the evidence when it is available, it noted.

BCG vaccination prevents severe forms of tuberculosis in children and diversion of local supplies may result in an increase of disease and deaths from the tuberculosis, it warned.
