在亨廷顿病中,发病年龄的60%的差异不能由亨廷顿基因突变解释。咖啡因使用者的亨廷顿病发病较早。评估生活方式因素与亨廷顿病高危人群运动表型转换的关系。运动表型转化和暴露于选定的生活方式和健康因素的关联进行了检查,使用考克斯比例风险分析调整的年龄,性别和重复长度。247例受试者中有36例(14.6%)发生表型转化。平均随访4.2年。更多的含咖啡因苏打水使用与表型转化的风险增加相关:中度使用风险比2.26(95%置信区间0.59,8.71),高使用风险比4.05(95%置信区间1.18,13.96)。亨廷顿氏病在喝含咖啡因苏打水的人中发病较早,而在喝其他含咖啡因饮料的人中发病较早。这一发现可能是虚假的,或者与咖啡因无关。
In Huntington’s disease, 60% of variance in onset age is not explained by the huntingtin gene mutation . Huntington’s disease onset was earlier in caffeine users . To assess the relationship of life style factors with motor phenoconversion among persons at risk for Huntington’s disease. Associations of motor phenoconversion and exposure to selected life style and health factors were examined using Cox proportional hazards analyses adjusted for age, gender and repeat length. Thirty-six of 247 subjects (14.6%) phenoconverted. Mean follow-up was 4.2 years. Greater caffeinated soda use was associated with increased hazard of phenoconversion: moderate use Hazard Ratio 2.26 (95% Confidence Interval 0.59, 8.71), high use Hazard Ratio 4.05 (95% Confidence Interval 1.18, 13.96). Huntington’s disease onset was earlier among consumers of caffeinated soda, but not other caffeinated beverages. This finding may be spurious, or not related to caffeine.
