To test the hypothesis that assortative mating for physical characteristics differs before and after major secular increases in height in an indigenous community in the Valley of Oaxaca, Mexico. Spouse pairs were identified in household and anthropometric surveys of a Zapotec-speaking community in 1978 (n = 68-70 pairs) and 2000 (n = 99-100 pairs). Height, weight, arm circumference, triceps skinfold and grip strength were measured. Assortative mating was calculated as Pearson correlations. Husband-wife correlations for age were high in both years (r = 0.96, 0.95). Assortative mating for height was significant in 1978 (r = 0.35, < 0.001) and in 2000 (r = 0.21, < 0.01), but decreased when ages were controlled (1978, 0.21, < 0.05; 2000, 0.11). Correlations (zero and second order, respectively) were low for the BMI (1978, 0.02, 0.02; 2000, 0.04, 0.05). Spouse correlations for grip strength were significant in both surveys (r = 0.25 to 0.45), but were reduced ( > 0.05) when ages of spouses were controlled (r = -0.02 to 0.16). Assortative mating for physical characteristics did not differ between surveys conducted before (1978) and after (2000) major secular increases in height in the community, and any possible genetic effect of the secular trend on assortative was likely negligible.
为了检验一个假设，即在墨西哥瓦哈卡山谷的一个本土社区中，身高的主要长期增长前后，身体特征的匹配交配是否存在差异。在 1978 年（n = 68-70 对）和 2000 年（n = 99-100 对）对一个说萨波特克语的社区进行家庭和人体测量调查时，确定了配偶对。测量了身高、体重、臂围、三头肌皮褶厚度和握力。通过皮尔逊相关系数来计算匹配交配程度。在这两年中，丈夫和妻子的年龄相关性都很高（r = 0.96，0.95）。1978 年（r = 0.35，<0.001）和 2000 年（r = 0.21，<0.01）时，身高的匹配交配程度具有统计学意义，但当控制年龄时，这种相关性降低（1978 年，0.21，<0.05；2000 年，0.11）。体重指数的相关性（零阶和二阶，分别）较低（1978 年，0.02，0.02；2000 年，0.04，0.05）。在两项调查中，握力的配偶相关性都具有统计学意义（r = 0.25 至 0.45），但当配偶的年龄得到控制时，这种相关性降低（>0.05）（r = -0.02 至 0.16）。在该社区身高发生主要长期增长之前（1978 年）和之后（2000 年）进行的调查中，身体特征的匹配交配程度没有差异，而且长期趋势对匹配的任何可能的遗传影响都可能可以忽略不计。
