Worship Is Good for Your Health

Newswise, July 10, 2017 — People who attend services at a church, synagogue or mosque are less stressed and live longer, according to new research from Vanderbilt University.

“Sometimes in health science we tend to look at those things that are always negative and say, ‘Don’t do this. Don’t do that,’” said Marino Bruce, a social and behavioral scientist and associate director of the Center for Research on Men's Health at Vanderbilt and an ordained Baptist minister.

The new research findings, however, are “encouraging individuals to participate in something,” he said.

According to the study, middle-aged (ages 40 to 65) adults – both men and women -- who attend church or other house of worship reduce their risk for mortality by 55 percent.

“Our findings support the overall hypothesis that increased religiosity – as determined by attendance at worship services – is associated with less stress and enhanced longevity,” said Bruce, a research associate professor of medicine, health and society at Vanderbilt. He is also a Baptist minister.

“We’ve found that being in a place where you can flex those spiritual muscles is actually beneficial for your health,” Bruce said.

The study, Church Attendance, Allostatic Load and Mortality in Middle-Aged Adults, was published May 16 in PLOS ONE, a multidisciplinary open access journal, using data from the National Health and Nutrition Examination Survey (NHANES), collected by the Centers for Disease Control and Prevention’s National Center for Health Statistics. The data are available to the public. Bruce is the main author of the study with Keith Norris, professor of medicine at the David Geffen School of Medicine at UCLA. There are nine other co-authors.

The researchers analyzed subjects’ attendance at worship services, mortality and allostatic load. Allostatic load is a physiological measurement of factors including cardiovascular (blood pressure, cholesterol-high density lipoprotein ration and homocysteine), nutritional/inflammatory (albumin, C-reactive protein) and metabolic (waist-hip ratio, glycated hemoglobin) measures. The higher the allostatic load, the more stressed an individual was interpreted as being.

Of the 5,449 people of all races and both sexes who were surveyed, 64 percent were regular worshipers, Bruce said. Non-worshipers had significantly higher overall allostatic load scores and higher prevalence of high-risk values for three of the 10 markers of allostatic load than did church-goers and other worshipers.

The effects of attendance at worship services remained after education, poverty, health insurance and social support status were all taken into consideration, Bruce said. The study did not address the effects of frequency of worship.

“We found that they go to church for factors beyond social support,” Bruce said. “That’s where we begin to think about this idea of … compassionate thinking, that we’re … trying to improve the lives of others as well as being connected to a body larger than ourselves.”

U.S. Asian populations may have different risk profiles for common geriatric conditions like cognitive and physical decline

Newswise, July 10, 2017– U.S. Asian populations may have different risk profiles for common geriatric conditions like cognitive and physical decline. Researchers from the PINE study—the first ever longitudinal study of U.S. Chinese older adults in the greater Chicago area—found the cognitive and physical function of U.S. Chinese immigrants may be greatly impacted by their social and cultural context more than non-immigrant populations, according to three studies published in the special issue of the Journals of Gerontology: Medical Sciences.

Each of the three studies focused on different components of geriatric syndromes: physical function decline, cognitive decline, and the relationship between social support and cognitive function.

The PINE Study from Rush University Medical Center was initiated in 2011 with over 3,000 U.S. Chinese older adults, who were surveyed 2 years after their first interview.

The status of physical function and cognitive function was examined, and profiles of socio-demographic characteristics were collected at each visit. In total, these studies provide an in-depth understanding of U.S. Chinese older adults and their health and present the need for more in-depth studies into the health of U.S. Asian communities to further efforts toward health equity.

Contrary to existing research, the PINE Study showed mixed findings regarding the effect of socioeconomic status on functional decline over time.

 Researchers had previously theorized that lower education and income were risk factors for rapid functional decline, but the PINE Study showed that only lower education was associated with worse physical function, and these effects diminished over time. Income was not related to physical performance or rate of decline in age.

“Our findings showed the unique characteristics of Chinese older immigrants. For example, lower income is usually associated with faster rate of physical performance decline in other populations, but we did not find a significant relationship in the U.S. Chinese aging population,” said Dr. XinQi Dong, MD, MPH, professor of Rush University Medical Center, and the principal investigator of the PINE study.

“In our population, individual income may not fully capture an individual’s socioeconomic status. There is also significant socioeconomic variability within the category of Asian Americans, contrary to the Model Minority conception, which may obfuscate the association between socioeconomic status and physical function decline.”

These findings regarding the complexities of the U.S. Chinese population were reflected in a study regarding cognitive function trajectory among Chinese older adults. Dr. Lydia Li, PhD, Associate Professor at the School of Social Work, University of Michigan, found that the change of different cognitive abilities, which represent components of cognitive function, varies greatly between individuals. For example, more highly educated individuals have clear advantages in all types of cognitive abilities at baseline, they have more decline in episodic and global memory in two years.

Further, men performed better than women in most cognitive abilities at baseline but had faster rates of decline in working memory.

“The sex differences in baseline and the change of cognition over a two-year period may be explained by a recent study indicating that older women are more resilient than their male counterparts in cognitive decline. However, they found women to perform better in some cognitive domains at baseline, and that study was based on a sample of primarily White adults with higher level of education,” Li continued.

“It may be gender inequality in Chinese society that renders older women at disadvantages in cognitive testing.”

Building on the idea that Chinese culture and context may influence cognitive status in late life, the PINE Study researchers also found that social relationships, in the form of both more social support and more social strain, were associated with better cognitive function.

“We were surprised that social strain was positively associated with cognitive function. This is not common in other populations. Social support and social strain are important facets in older adults' social life,” said Shaoqing Ge, MPH, PhD candidate at Duke University School of Nursing.

The reason, Ge noted, may be culturally-based: “this finding may be the result of the unique appraisals among Chinese older adults. Reporting higher social strain may reflect a more socially engaged lifestyle.

Influenced by the traditional Chinese culture and norm, the U.S. Chinese older adults view their active engagement in the family as indications of self-value. Consequently, U.S. Chinese older adults may interpret social strain in a positive way.”
