Toward a better understanding of the comparatively high prostate cancer incidence rates in Utah

Latent Archetypes of the Spatial Patterns of Cancer

The cancer atlas edited by several countries is the main resource for the analysis of the geographic variation of cancer risk. Correlating the observed spatial patterns with known or hypothesized risk factors is time-consuming work for epidemiologists who need to deal with each cancer separately, breaking down the patterns according to sex and race. The recent literature has proposed to study more than one cancer simultaneously looking for common spatial risk factors. However, this previous work has two constraints: they consider only a very small (2-4) number of cancers previously known to share risk factors. In this article, we propose an exploratory method to search for latent spatial risk factors of a large number of supposedly unrelated cancers. The method is based on the singular value decomposition and nonnegative matrix factorization, it is computationally efficient, scaling easily with the number of regions and cancers. We carried out a simulation study to evaluate the method's performance and apply it to cancer atlas from the USA, England, France, Australia, Spain, and Brazil. We conclude that with very few latent maps, which can represent a reduction of up to 90% of atlas maps, most of the spatial variability is conserved. By concentrating on the epidemiological analysis of these few latent maps a substantial amount of work is saved and, at the same time, high-level explanations affecting many cancers simultaneously can be reached.

"A Temple of God": A Qualitative Analysis of the connection Between Spiritual/Religious Beliefs and Health Among Mormons

In the last decades, studies have increasingly shown an association between religious/spiritual beliefs (R/S) and several health outcomes. In this context, Mormons provide an intriguing case for such investigation because Mormonism stands out for its commitment to the "Word of Wisdom" with several restrictions and recommendations. Despite the consolidated wide array of evidence, showing that the relationship between "Word of Wisdom" and health may usually have a protective effect in North-American studies, little is know about this community in other countries and, to our knowledge, no health studies have ever been carried out in European and Spanish Mormons. The present qualitative study aims to fill this gap, exploring the discourses, opinions, and attitudes of the members of the Church of Jesus Christ of Latter-day Saints about the recommendations of the Health Law and the "Word of Wisdom" on their health. In the analysis, six themes appeared during the coding process and were converted in the following categories: Theme 1 Body as a Temple, Theme 2 Promises of blessing, Theme 3 Healthy lifestyle, Theme 4 Stigma, Theme 5 Damage to the family, and Theme 6 Spiritual Performance. We found that fulfilling the "Law of Wisdom" may lead Mormons to take care of their health, and to have a network of support from church leaders, who may act as health promoters. Religiosity tends to insert values and behaviours that seem to benefit individual's health and protect their families, such as the non-use of substances and the preservation of a "healthy body" (i.e. "body as a temple"). However, some stigma and isolation may appear in contact with other groups due to these restrictions and limitations.

Health Impacts of Religious Practices and Beliefs Associated with The Church of Jesus Christ of Latter-Day Saints

The aim of the study is to discuss the relationship between lifestyle marked by The Church of Jesus Christ of Latter-day Saints and health. PubMed, CINAHL, PsycINFO, WOS y Scopus were the databases used for this literature review, with these descriptors: "Mormons", "mormons religion", "health". Inclusion criteria were articles with full text available, published between 2005 and 2016, in English or Spanish language. Results show that following the restrictive Mormon doctrine generates beneficial effects for the health. Habits related to toxics and food, as well as social support, from family and Mormon community are an important basis for good health. On the other hand, not following the prescriptions or leaving the group, opposed sexual identities or not fulfilling the roles associated with women are associated with worse mental and physical health.

Cancer screening practices among Amish and non-Amish adults living in Ohio Appalachia

PURPOSE

The Amish, a unique community living in Ohio Appalachia, have lower cancer incidence rates than non-Amish living in Ohio Appalachia. The purpose of this study was to examine cancer screening rates among Amish compared to non-Amish adults living in Ohio Appalachia and a national sample of adults of the same race and ethnicity in an effort to explain cancer patterns.

METHODS

Face-to-face interviews focusing on perception of risk, cancer screening behaviors, and screening barriers were conducted among Amish (n = 134) and non-Amish (n = 154) adults living in Ohio Appalachia. Cancer screening rates were calculated and then compared to a national sample of adults.

FINDINGS

More Ohio Appalachia non-Amish males (35.9% vs 14.5%; P= .022) and females (33.3% vs 12.5%; P= .008) reported that they would probably develop cancer in the future compared to Amish males and females. Amish adults had significantly lower prostate (13.5% vs 63.1% vs 44.6%; P < .001), colorectal (males: 10.3% vs 40.0% vs 37.2%, females: 8.6% vs 31.6% vs 42.9%; P < .001), cervical (48.0% vs 84.0% vs 80.0%; P < .001), and female breast (24.8% vs 53.7% vs 56.9%; P < .05) cancer screening rates compared to Ohio Appalachia non-Amish participants and a national sample of adults, respectively. Barriers to cancer screening were similar among the 2 Ohio groups; however, Amish males reported that prostate cancer screening was not necessary more often than did Ohio Appalachia non-Amish males (78.6% vs 16.7%; P= .003).

CONCLUSIONS

Lower rates of cancer screening were documented among the Amish and may be a contributing factor to the reduced cancer incidence rates reported among this population.

The law and incomplete database information as confounders in epidemiologic research on occupational injuries and illnesses

BACKGROUND

Capture-recapture studies report undercounting of work injuries/illnesses with days away from work (DAFW) in the Bureau of Labor Statistics annual Survey of Occupational Injuries and Illnesses (BLS SOII) by 25-68% depending on the state and undercounting by various state workers' compensation (WC) systems of eligible claims by 5-35%.

METHODS

Statutory/regulatory criteria defining eligible cases are used to adjust counts in the 1998-2001 Minnesota's WC system and the BLS SOII to permit comparison and to evaluate the recent studies. Missing information in the employer database used in the capture-recapture studies is tabulated. An attempt is made to harmonize results with two additional databases counting work injuries.

RESULTS

Counts in the BLS SOII moderately undercount by 10-16% the number of WC cases. We believe that matching in capture-recapture studies is adversely affected by misperceptions regarding the application of statutory/regulatory eligibility criteria and by missing data. The result is that the reported undercounts in both the BLS SOII and several state WC databases are overstated in the capture-recapture studies. Although three of four databases can be approximately harmonized, the fourth cannot.

CONCLUSIONS

More precisely targeted information is needed before decisions regarding redesign of the BLS survey are made or before legislative or administrative changes in the WC are contemplated.

Family history of prostate and breast cancer and the risk of prostate cancer in the PSA era

BACKGROUND

A family history of prostate cancer (PCa) or breast cancer (BCa) has been associated with the risk of PCa, but the risks were inconsistent in terms of the affected family members, and data in the PSA era are limited.

METHODS

This study included a subcohort of the Health Professionals Follow-Up Study composed of a highly PSA screened population from 1986 to 2004 with 3,695 PCa cases identified. Questionnaires and a food frequency questionnaire were administered every other and every 4 years, respectively. Family history of PCa and BCa was ascertained in 1990, 1992, and 1996. All statistics were two-sided.

RESULTS

A family history of PCa in both a father and brother(s) was associated with a 2.3-fold increased risk of PCa [95% confidence interval (CI) = 1.76-3.12]. Men with a father or brother(s) with a PCa diagnosis at age<60 and >or=60 had 2.16- and 1.95-fold increased risk of PCa, respectively. A family history of PCa was related to early-onset PCa (<65 years: RR = 2.25, 95% CI = 1.95-2.60) and weakly to late-onset PCa (>or=65 years: RR = 1.67, 95% CI = 1.52-1.85). History of BCa in a mother or a sister was associated with a 1.22-fold increased risk of PCa (95% CI = 1.08-1.38).

CONCLUSION

A family history of PCa or BCa significantly increases PCa risk. These associations are evident in a population with widespread PSA screening.

Cancer incidence among Mormons and non-Mormons in Utah (United States) 1995-1999

BACKGROUND

Population-based Utah Cancer Registry data were linked with Latter-day Saint (LDS or Mormon) Church membership records to obtain site-specific cancer incidence for LDS and non-LDS populations in Utah during 1995-1999.

METHODS

Analyses were based on 27,631 incident cases of cancer identified among whites. Restriction to whites was made because of the small number of nonwhites, approximately 5%, in the state during the study period. The direct method was used to age-adjust the rates to the 2000 U.S. standard population.

RESULTS

Significantly lower cancer incidence rates per 100,000 were observed among LDS compared with non-LDS males (287.2 vs. 321.1) and females (247.7 vs. 341.0). The lower rates are primarily explained by smoking-related cancers and female breast cancer. If the overall cancer incidence rate in LDS had occurred in the non-LDS population, 2.9% or 421 fewer cases would have occurred among males and 7.9% or 1,025 fewer cases would have occurred among females during the study period.

CONCLUSIONS

Given our current knowledge of risk factors for cancer, differences between LDS and non-LDS in smoking for males and smoking and sexual and reproductive behaviors in females primarily explain the lower risk of cancer in LDS populations.
