Authors: Loren Marks (BYU, lead), Harold Koenig (Duke), Shima Baughman, Jared Robbins, Paul Lambert, Elijah Nevares. Published June 4, 2026. > - **Headline claim**: Across 1,069 significant-finding studies spanning 15 physical-health domains, positive associations outnumber negative by roughly 7:1 (876 positive, 124 negative, 69 mixed). Strongest ratios: cigarette smoking 90:1, substance abuse ~43:1, longevity ~15:1, cerebrovascular disease 10:1. Weakest: disease prevention/detection/compliance ~2:1 (and weakening post-2010). > - **Why it matters to the rigor question**: The report is the single primary source behind the whole downstream chain (the two news write-ups and the Wired Word lesson all trace here). If its rigor choices bias the result, that bias propagates to every retelling. It does not fabricate — but three specific method choices manufacture a lopsided headline. > - **Verified rigor findings (from the full PDF)**: > 1. **Null findings excluded by design.** The methodology states plainly that the series "focuses specifically on studies reporting statistically significant associations... This excludes null findings." The 7:1 is a ratio *among studies that already found a significant effect* — not "religion helps 7x more than it harms" in absolute terms. > 2. **Vote-counting, not meta-analysis.** The report tallies positive vs. negative significant studies per domain. No effect-size pooling, no confidence intervals, no per-study confounder adjustment at the synthesis level, no publication-bias testing (no funnel plots / trim-and-fill). > 3. **No engagement with dissent.** Independent skeptical work (Garssen et al. 2020 meta-analysis; Prati 2023, which found negligible effects using unpublished longitudinal datasets) is absent. > - **Bottom line**: The underlying Handbook is genuinely credentialed (Oxford UP; VanderWeele is a serious Harvard epidemiologist), and many primary studies the report cites are rigorous prospective cohorts. But the report's own synthesis layer is a box-score vote count with nulls removed and no bias testing, produced by a religiously affiliated institute that closes with a religious-freedom policy ask. That combination compresses a real-but-moderate literature into an astonishing soundbite ("7:1," "90:1") that then travels through faith-aligned media without friction. The rigor choices do not just risk an echo chamber — they build the echo at the source. > ## 📖 Main Content > ### What the report actually did > The authors did not run new studies or a fresh systematic search. They curated from the 2024 *Handbook*, which itself screened a very large corpus (tens of thousands of studies; the report cites Google Scholar decade-counts of 2,980 → 16,600 → 19,900 → 17,400 from 1985–2025) down to the most methodologically rigorous. From that curated pool, the physical-health report counts 1,069 studies with significant findings across 15 domains and reports the direction of each. This is a narrative/vote-count synthesis, explicitly framed as "a concise yet careful overview" of the Handbook rather than an independent meta-analysis. > ### The null-exclusion choice (the crux) > The report is transparent about excluding nulls: it argues null findings are "typical in any body of medical research" and "neither support nor undermine the central claim." That is defensible *if* the question is narrowly "when religion shows a significant association with health, which direction does it point?" It is misleading when the ratio is then presented publicly as "religion is beneficial 7x more often than harmful," because the denominator has already dropped every study that found no effect. Two different claims get conflated: direction-among-detected-effects (what was measured) vs. prevalence-of-benefit (what readers hear). > ### Vote-counting vs. effect size > Box-score synthesis counts studies, not magnitudes. A domain could show a 90:1 count with uniformly tiny effects, or a 2:1 count with large ones — the ratio does not say. The field's own leading methodologist, VanderWeele, has argued elsewhere that religion-health effect sizes are small to moderate at best and has developed specific causal-inference methods for longitudinal data. The report cites his rigorous primary studies (e.g., Kim & VanderWeele 2019; Chen & VanderWeele 2018) but does not adopt his cautionary framing about magnitude or causation at the synthesis level. > ### Correlation, causation, and self-selection > The report's language slides between "associated with" (correct) and causal implication (the mechanisms sections read as causal stories). The "threshold effect" — benefits concentrating among weekly-or-more attenders — is presented as dose-response evidence for a causal effect. But it is equally consistent with self-selection: people healthy enough, resourced enough, and socially connected enough to sustain weekly attendance differ systematically from those who cannot. Several cited primary studies are prospective cohorts that partially address this with baseline controls; the *synthesis* does not foreground reverse causation as a live alternative. > ### Where the report is more careful than its retellings > Credit where due, and important for a fair verdict: the report concedes disease prevention/compliance is only ~2:1 and has weakened since 2010 (including post-COVID); it flags that some stress-hormone findings are cross-sectional only; it states religious healing should complement, not replace, medical care; and it acknowledges harmful expressions of religion exist. The report is markedly more hedged than the *Deseret*/*Religion Unplugged* coverage or the Wired Word lesson. The echo chamber worsens *downstream* — each retelling strips the hedges. > ### The LDS thread in the flagship evidence > The marquee longevity/cancer findings originate with Enstrom's studies of ~9,844 Latter-day Saints (1998–99). The report is honest that Enstrom "largely replicated" the effect among non-LDS physically-active nonsmoking weekly attenders, and it cites newer, larger, non-denominational cohorts (Li et al. 2016 N=74,534; Idler et al. 2017; Kim & VanderWeele 2019). So the evidence is not LDS-only — but the institutional chain (BYU institute, LDS-linked flagship studies, LDS-owned *Deseret*/KSL among the press) is worth naming. > ### Uncertainty / verification notes > This deep-read is based on the full 50-page report PDF plus the landing page, cross-checked against external literature (Garssen 2020; Prati 2023; VanderWeele's commentaries).

As we begin the second quarter of the 21st century, what do the best medical and social science studies tell us about connections between religion and health? The *Religion and Human Flourishing* series, a three-part research series by Wheatley Institute, answers this question by synthesizing the findings from Koenig, VanderWeele, and Peteet’s *Handbook of Religion and Health* (3rd ed., 2024)— a collection of hundreds of rigorous and high-quality studies that make up the most comprehensive and methodologically discerning review on religion and health to date. Part one of *Religion and Human Flourishing* focuses on [religion and mental health](https://wheatley.byu.edu/religion-and-mental-health), while part three focuses on religion and social health. **This current report, *Religion and the Physical Health Connection*, represents part two of the series. It specifically examines the relationship between religious involvement and measurable physical health outcomes.** Drawing on the most rigorous, high-quality studies that met the *Handbook*’s stringent inclusion criteria, 876 of 1,069 studies (82%) reported significant findings which identified positive correlations between religion and physical health. In contrast, 124 studies (12%) reported negative associations (for example, unhealthy religious influences), while 69 studies (6%) yielded mixed or complex results. **Taken together, among the best available evidence, positive associations outnumber negative ones by roughly 7:1.** The research generally finds significant positive correlations between higher religiosity and better physical health across all 15 of the analyzed health factors. However, the strength of these relationships varies widely depending on the specific phenomenon. Across different areas, the ratio of rigorous studies showing positive (healthy) versus negative (unhealthy) connections ranges from less than 2:1 to as high as 90:1. **These findings underscore a consistent conclusion: when studied carefully and rigorously, high religious involvement is significantly associated with more than a dozen measurable benefits for physical health.** The strongest positive relationships were observed in connection with cerebrovascular disease (10:1), all-cause mortality and longevity (approximately 15:1), substance abuse and addiction (approximately 43:1), and cigarette smoking (90:1). A bar graph showing the percentage of studies that found different relationships between religion and physical health outcomes. 81.9% of studies found positive associations, 11.6% found negative associations, and 6.5% found mixed or complex associations. In addition, research consistently shows a threshold effect: the benefits of religion concentrate among those with sustained, high engagement. Active participation is linked to better mental and physical health—including lower cancer rates, greater longevity, and stronger marriages and families. Meaningful commitment tends to yield the greatest benefits, typically seen among weekly attenders across ages and faiths. From a health-promotion perspective, this growing body of evidence provides science-based support for active religious involvement, with wide-ranging [mental](https://wheatley.byu.edu/religion-and-mental-health), physical, and relational benefits extending across individuals, families, and communities. While religion is not a cure-all, and harmful expressions do exist, the overall pattern is neither mixed nor evenly divided. Instead, across hundreds of high-quality studies, positive associations outweigh negative ones by wide margins. As societies confront rising rates of mental illness, addiction, social fragmentation, and family instability, the evidence suggests that **religion remains a consequential and often underrecognized contributor to human flourishing**. Understanding how, when, and why religion promotes well-being is therefore not only an academic concern, but a matter of broad social importance. * Higher religiosity is overwhelmingly associated with lower rates of cigarette smoking, with positive findings outnumbering negative ones by 90:1—the strongest ratio of any health phenomenon examined in this series. This protective effect likely arises from religious teachings that honor the body as sacred; from strong parental and community modeling; from prosocial peer networks; and via faith-based coping practices that offer healthy alternatives to addiction. * Religion exerts one of its strongest protective effects against substance abuse, with 94% of high-quality studies showing lower rates of addiction among the more religious. This protective influence operates through multiple pathways—strengthening internal self-control, fostering prosocial peer and family networks, and even engaging the same neural reward circuits implicated in addiction—thereby reducing both the development and persistence of substance abuse disorders while promoting healthier, more adaptive coping. * * Higher religiosity is associated with lower rates of coronary heart disease (approximately 4:1), hypertension (approximately 5:1), and cerebrovascular disease (approximately 10:1). These protective effects appear to operate through biological, psychological, behavioral, and social pathways—reducing anger and stress, strengthening relationships and social capital, and promoting healthier lifestyles that lower cardiovascular and stroke risk. We note that while religion is generally associated with healthier patterns of general disease prevention, detection, and treatment compliance, this domain shows the weakest positive-to-negative ratio (approximately 2:1) among all 15 physical health phenomena. * * * #### Policy Considerations * * Health and social service professionals should be equipped to understand how spiritual beliefs and religious practices affect coping, treatment adherence, and recovery. Integrating faith literacy into professional training can strengthen trust, engagement, and outcomes—without compromising critical health care or clinical standards. Such efforts would empower health care workers to better treat and care for the “whole patient.” Most patients value this aspect of care, but few physicians are trained or experienced in this aspect, aside from palliative care specialists. * Continued funding for rigorous, longitudinal research is needed to clarify how religion influences health through biological, psychological, and social pathways. A new generation of studies can build on strong existing evidence connecting religiosity with lower rates of cancer, stroke, and heart disease—helping identify the mechanisms through which faith contributes to physical health and longevity. * * The benefits from religious living identified in this report are dependent upon the ability of individuals and groups to freely practice and live out their specific faith commitments. Legal and cultural norms that protect the right of religious freedom for all and recognize the benefits that religious life and commitments bring to individuals and society as a whole will enhance the likelihood of society experiencing such benefits.
