Phleboliths, and especially diverticular disease and hiatus hernia, are rarer in developing countries than in economically more developed communities, but all three conditions were as common in Black as in White Americans. This finding suggests that they are due to environmental rather than to genetic causes. A deficient intake of dietary fibre may be the common factor predisposing to these three conditions.
静脉石，尤其是憩室病和食管裂孔疝，在发展中国家比在经济更发达的地区更为少见，但这三种情况在非裔美国人中与在美国白人中一样常见。这一发现表明它们是由环境因素而非遗传因素导致的。膳食纤维摄入不足可能是引发这三种情况的共同因素。
