Spouse correlations in cardiovascular risk factors were investigated using data on 2,836 spouse pairs collected in the Busselton Population Health Surveys over the period 1966-1981. The risk factors considered were systolic blood pressure, diastolic blood pressure, body mass index, triceps fatfold, cholesterol, and forced expiratory volume (1 second). Statistically significant positive correlations (p < 0.01) were found for all (age-adjusted) variables. There was a statistically significant decreasing trend in the correlations for systolic blood pressure with marriage duration (trend p < 0.01). Although no other variables showed statistically significant trends, the correlations for diastolic blood pressure (p = 0.29), body mass index (p = 0.14), and forced expiratory volume (p = 0.16) also decreased with marriage duration, and correlations for cholesterol (p = 0.61) and triceps fatfold (p = 0.99) increased with marriage duration. These results suggest that there is spousal concordance in cardiovascular risk factors. The lack of consistent increasing trends in the correlations with marriage duration suggests that assortative mating may be a more likely explanation than the sharing of a common environment.
利用1966年至1981年期间在巴瑟尔顿人群健康调查中收集的2836对配偶的数据，研究了心血管危险因素中的配偶相关性。所考虑的危险因素包括收缩压、舒张压、体重指数、肱三头肌皮褶厚度、胆固醇和用力呼气量（1秒）。所有（年龄调整后）变量均发现具有统计学意义的正相关性（p < 0.01）。收缩压与婚姻持续时间的相关性存在统计学意义的下降趋势（趋势p < 0.01）。虽然没有其他变量显示出统计学意义的趋势，但舒张压（p = 0.29）、体重指数（p = 0.14）和用力呼气量（p = 0.16）的相关性也随婚姻持续时间而下降，胆固醇（p = 0.61）和肱三头肌皮褶厚度（p = 0.99）的相关性随婚姻持续时间而增加。这些结果表明心血管危险因素存在配偶一致性。与婚姻持续时间的相关性缺乏一致的上升趋势表明，选型交配可能比共同环境的影响更有可能是其原因。
