Well, no. There\u2019s a good reason that this study has found something different, and that\u2019s because it\u2019s not asking quite the same question.<\/p>\n
You see, working out the relationship between religion and health is actually quite complicated. If you take the straightforward approach the answer is clear: religious people are unhealthier and die younger than the non-religious.<\/p>\n
The reason for that is obvious. Religious people tend to be poorer and less well educated. As a result, most studies try to work out whether religious people are healthier after<\/span> adjusting for these differences.<\/p>\n So the key question boils down to this: which differences should you adjust for? Your decision on this will affect the answer you get.<\/p>\n Most studies adjust for basic demographic factors. Older people and women are more likely to be religious, and both these affect your chances of heart attacks. Most studies also adjust for education and income level.<\/p>\n The rationale is our old friend, the arrow of causality. While being older might cause you to be more religious, being religious doesn\u2019t cause you to be older!<\/p>\n But there are also a host of lifestyle factors that make heart disease more likely (smoking, lack of exercise, overeating). Here\u2019s where it starts to get more difficult, because religion could definitely cause you to be a nonsmoker.<\/p>\n Many studies adjust for these lifestyle factors. But you can go a step further \u2013 and that\u2019s what they did in this study.<\/p>\n Lifestyle contributes to heart disease by affecting things like your cholesterol levels and blood pressure, and by making you more likely to be diabetic. If you adjust for all of these, then you are really getting down to a nitty gritty question.<\/p>\n And so the question they were asking in this study was really very specific. They wanted to know if, apart from all the physical things that could link religion to heart disease, there is some other, unexplained factor at work.<\/p>\n So what\u2019s this study about, then?<\/span><\/span><\/p>\n With all that in mind, let\u2019s take a quick look at this study. What they did was follow about 5,000 Americans recruited as part of another study and chosen to be ethnically diverse and regionally representative. They recorded heart attacks and strokes over 4 years.<\/p>\n As expected, nonreligious people were much more healthy than the religious. They had lower blood pressure, were leaner, and were less likely to be diabetic. They were, however, more likely to be smokers.<\/p>\n The effects of this could be detected in their organs. The arteries of religious people were more damaged and their hearts were enlarged.<\/p>\n But the nonreligious also better educated, more likely to be white or Chinese, and more likely to be men. All of these would affect your lifestyle.<\/p>\n So they adjusted for age, sex, race, education and income, like many other studies before have done. Crucially (and unlike other studies), they also adjusted for blood pressure, diabetes, obesity, and cholesterol.<\/p>\n In other words, whatever effect religion has on health (for good or bad), it must do it by affecting known risk factors in some way.<\/p>\n I guess that\u2019s not too surprising. But other studies have found that psychological factors can lead to heart disease. This study suggests that these psychological factors aren\u2019t significantly affected by religion.<\/p>\n The really interesting thing is\u2026<\/span><\/span><\/p>\n One last thing \u2013 and this is what I thought was the really mind-blowing result from this study.<\/p>\n They found that religious people smoked less. This was one of only two lifestyle factors that remained after they adjusted for all the demographic differences between the religious and non-religious (age, gender, race, education and income).<\/p>\n That\u2019s something that\u2019s commonly observed, and it may be because religion provides social pressure and support to help people quit.<\/p>\n But the study also found that religious people were fatter (again, after adjusting for demographic factors). The effect was large \u2013 religious people were 50-60% more likely to be obese.<\/p>\n That\u2019s a result that has been seen in other studies, but is altogether more difficult to explain! Donald Lloyd-Jones, the study lead, put it like this<\/a>:<\/p>\n \u201cThe obesity story is interesting, and we tried a lot of different ways to get it to go away\u2014looking at social, demographic, and psychosocial factors\u2014and really didn\u2019t see any clear explanation for it,\u201d said Lloyd-Jones. \u201cSo we\u2019re left with this observation, and we\u2019re not really sure what\u2019s the cart and what\u2019s the horse. We don\u2019t really know if there is something about religious participation that leads to obesity, or if it\u2019s the other way around, and that heavier people might seek out religious and spiritual experiences because of things like stigmatization.\u201d<\/p><\/blockquote>\n <\/p>\n You might have seen news reports about a recent study showing that religious people are no healthier than non-religious. The cynical among you might be wondering what on Earth\u2019s going on here, given that other studies have shown the opposite! A classic example of scientists proving whatever they want to, perhaps? Well, no.
