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.)

Washington DC, Jun 29: Young children with narrow retinal artery diameters were more likely to develop higher blood pressure, and children with higher blood pressure levels were more likely to develop retinal microvascular impairment during early childhood, according to a new study.

The first study to show this connection in children was published today in Hypertension, an American Heart Association journal.

High blood pressure, the main risk factor for the development of cardiovascular disease (CVD), can manifest as early as childhood, and the prevalence of high blood pressure among children continues to rise. In previous studies, analysis of blood vessels in the retina has shown promise as a predictor of CVD risk among adults. In the study titled, "Retinal Vessel Diameters and Blood Pressure Progression in Children," researchers sought to predict the development of high blood pressure in children over four years based on retinal blood vessel measurements.

"Hypertension continues as the main risk factor for the development of cardiovascular diseases and mortality," says Henner Hanssen, M.D., the study's lead author and a professor in the department of sport, exercise and health at the University of Basel in Switzerland. 

"Primary prevention strategies are needed to focus on screening retinal microvascular health and blood pressure in young children in order to identify those at increased risk of developing hypertension. The earlier we can provide treatment and implement lifestyle changes to reduce hypertension, the greater the benefit for these children."

Researchers screened 262 children ages six to eight from 26 schools in Basel, Switzerland, in 2014, for baseline blood pressure and retinal arterial measurements. Both measures were taken again in 2018. Blood pressure measurements at both baseline and follow-up were performed in a sitting position after a minimum of five minutes of rest and were categorized based on the American Academy of Pediatrics' blood pressure guidelines. These guidelines utilize the same measurements as the American Heart Association/American College of Cardiology 2017 Guideline for the Prevention, Detection, Evaluation, and Management of High Blood Pressure in Adults.

Results from the analysis indicate: children with narrower retinal vessel diameters at baseline developed higher systolic blood pressure at follow-up; retinal vessel diameters could explain 29 -31 per cent of the changes in systolic blood pressure progression between 2014 and 2018; children with higher blood pressure levels at baseline developed significantly narrower arteriolar diameters at follow-up, depending on weight and cardiorespiratory fitness; and initial blood pressure measures explained 66-69 per cent of the change in retinal arteriolar diameter from baseline to follow-up.

"Early childhood assessments of retinal microvascular health and blood pressure monitoring can improve cardiovascular risk classification. Timely primary prevention strategies for children at risk of developing hypertension could potentially counteract its growing burden among both children and adults," said Hanssen.

Researchers noted limitations of their study include that they could not confirm blood pressure measurements over a single 24-hour period, so they would not account for "white coat" hypertension, a condition where patients have high blood pressure readings when measured in a medical setting.

Developmental stage including puberty status of each child was not accounted for in the study, as well as genetic factors or birth weight - variables that could impact blood pressure development and microvascular health.

In addition, reference values for appropriate retinal vessel diameters in children do not currently exist, so future studies are needed to determine age-related normal values during childhood.

Washington, Aug 2: Children under the age of five have between 10 to 100 times greater levels of genetic material of the coronavirus in their noses compared to older children and adults, a study in JAMA Pediatrics said Thursday.

Its authors wrote this meant that young children might be important drivers of Covid-19 transmission within communities -- a suggestion at odds with the current prevailing narrative.

The paper comes as the administration of US President Donald Trump is pushing hard for schools and daycare to reopen in order to kickstart the economy.

Between March 23 and April 27, researchers carried out nasal swab tests on 145 Chicago patients with mild to moderate illness within one week of symptom onset.

The patients were divided into three groups: 46 children younger than five-years-old, 51 children aged five to 17 years, and 48 adults aged 18 to 65 years.

The team, led by Dr Taylor Heald-Sargent of the Ann & Robert H. Lurie Children's Hospital, observed, "a 10-fold to 100-fold greater amount of SARS-CoV-2 in the upper respiratory tract of young children."

15 countries with the highest number of cases, deaths due to the Covid-19 pandemic

The authors added that a recent lab study had demonstrated that the more viral genetic material was present, the more infectious virus could be grown.

It has also previously been shown that children with high viral loads of the respiratory syncytial virus (RSV) are more likely to spread the disease.

"Thus, young children can potentially be important drivers of SARS-CoV-2 spread in the general population," the authors wrote.

"Behavioral habits of young children and close quarters in school and daycare settings raise concern for SARS-CoV-2 amplification in this population as public health restrictions are eased," they concluded.

The new findings are at odds with the current view among health authorities that young children -- who, it has been well established, are far less likely to fall seriously ill from the virus -- don't spread it much to others either.

However, there has been fairly little research on the topic so far.

One recent study in South Korea found children aged 10 to 19 transmitted Covid-19 within households as much as adults, but children under nine transmitted the virus at lower rates.

Dear parents, if you want your children to have proper sleep, read this carefully. Joining a growing list of studies that tell parents to shun devices at bed-time, researchers say that children who use devices and decide what time they go to sleep, achieve less sleep and feel more sleepier the following day than their peers.

The study of children in this age-group (aged 11 to 13 years), published in the New Zealand Medical Journal, found most (72 per cent) of the 163 students interviewed by University of Otago researchers achieved recommended guidelines of an average 9 to 11 hours sleep nightly over one week.

"But that also means that almost one in four students did not achieve sleep within these guidelines, which highlights an area for improvement," said study researcher Kate Ford.

However, consistent with previous research in 15 to 17-year-old New Zealanders, the study results show less sleep on the nights where devices are used in the hour before bed.

According to the researchers, students who used devices before going to sleep were also more likely to report that they felt sleepy the following morning. Watching television before bed had no significant effect on sleep length.

There were also some interesting observations over the weekends where students went to bed later but woke later achieving similar sleep length to the school days, the researchers said.

A small group of students (six per cent) who reported less than seven hours of sleep, including a small number reporting not sleeping at all, according to the study,

Therefore, while the average across the week of 72 per cent of students reporting adequate sleep is reassuring, it is far from the goal of every child achieving sleep within the recommended guidelines," Ford said.

Dr Paul Kelly, head of the Sleep Health Service at Canterbury District Health Board, supervised the study and explained that the foundations for good health are based on proper nutrition, regular exercise and good sleep quality.

Sleep quality is often overlooked as a contributory factor to poor health.

"The study findings suggest the need for parental guidance around bedtimings and moderation of the use and availability of electronic devices before bed," Kelly said.

"Respect and protect your sleep, as good daytime functioning is reliant on adequate sleep," Kelly added.
