Ninety-seven percent of a randomly selected sample of 2600 adults (age range 21 to 92 years) from the Napier City electoral area were surveyed for age and sex distribution of blood pressure. The sample included those currently receiving drug treatment for elevated pressures. There were approximately 400 in each decade and the sex ratio slightly favoured females. Casual systolic pressures rose with age whereas the diastolic rose to approximately age 50 and thereafter remained steady or slightly declined. Before age 50 years males had higher systolic pressures than females and thereafter the mean levels for females exceeded those for the males. Mean systolic pressures for this New Zealand sample population were higher by 2-4mmHg for all ages than the levels reported for the United States National Health Survey 1960-62.
从内皮尔市选区随机抽取了2600名成年人（年龄范围为21至92岁）作为样本，其中97%的人接受了血压的年龄和性别分布调查。样本包括目前正在接受高血压药物治疗的人群。每个十年年龄段大约有400人，性别比略微偏向女性。偶测收缩压随年龄增长而升高，而舒张压在大约50岁时上升，此后保持稳定或略有下降。50岁之前男性的收缩压高于女性，此后女性的平均水平超过男性。该新西兰样本人群的平均收缩压在所有年龄段都比1960 - 1962年美国国家健康调查所报告的水平高2 - 4毫米汞柱。
