This investigation studied the potential effects of societal modernization on Samoan children's blood pressure and heart rate reactivity to a standardized television video game procedure. Ethnic Samoan children were sampled from Western Samoa (N = 72), a relatively underdeveloped country with a largely agricultural economy, and American Samoa (N = 70), a territory of the United States that has undergone substantial modernization due to recent economic aid. Results indicated that Western Samoans demonstrated significantly greater systolic blood pressure, diastolic blood pressure, and heart rate reactivity than American Samoans. These data, in conjunction with previous data, suggest that the hemodynamic effects of an acute stressor are inversely associated with societal modernization and an individual's adoption of a lifestyle reflecting integration into a modernized society. Further work is needed to examine the implications of this hypothesis and the associations among concrete measures of modernization and children's cardiovascular risk.
本研究探讨了社会现代化对萨摩亚儿童血压及心率的潜在影响，这些影响是在儿童面对标准化电视游戏程序时产生的。研究从西萨摩亚（N = 72）和美属萨摩亚（N = 70）抽取了萨摩亚族儿童作为样本。西萨摩亚是一个相对不发达的国家，经济以农业为主；美属萨摩亚是美国的一个领土，由于近期的经济援助，已经历了显著的现代化进程。结果表明，与美属萨摩亚儿童相比，西萨摩亚儿童在收缩压、舒张压及心率反应方面显著更高。这些数据与之前的数据共同表明，急性应激源对血液动力学的影响与社会现代化以及个体采用反映融入现代社会的生活方式呈负相关。需要进一步开展研究，以检验这一假设的意义，以及现代化的具体衡量指标与儿童心血管风险之间的关联。
