The study aims to investigate secular changes in adult height among Nordic reference populations during the last four decades and in parents of Swedish study participants, and to study during which growth phase(s) infancy, childhood or puberty changes in height and tempo occurred.
Length and height data were obtained from publications on populations used as current and previous national height references in Denmark, Finland, Norway and Sweden. Measurements from birth until adult height and original parental heights of participants in Swedish reference populations born 1956, 1974, and 1990 were used.
Adult height has increased progressively in Nordic populations born in 1950s-1990s; for females by 6 mm/decade Norway, 4 mm; Sweden, 6 mm; Finland and Denmark, 7 mm; for males by 9 mm/decade, in Sweden, 5 mm; Finland, 7 mm; Denmark 8 mm; Norway, 15 mm. This was due to more growth during childhood despite earlier timing of mid-puberty. Heights of Swedish parents born 1920s-1960s increased 11 mm/decade for mothers, 14 mm/decade for fathers.
The Nordic countries comprise some of the tallest populations in the world yet continue to show a positive secular change in adult height alongside a faster tempo of growth by earlier timing of puberty, highlighting the need to regularly update national height references.
本研究旨在调查过去四十年中北欧参考人群中成年人身高的长期变化，以及瑞典研究参与者父母的身高变化，并研究身高和生长速度的变化发生在哪个生长阶段（婴儿期、儿童期或青春期）。
长度和身高数据来自丹麦、芬兰、挪威和瑞典作为当前和以前的国家身高参考人群的出版物。使用了瑞典参考人群中 1956 年、1974 年和 1990 年出生的参与者的出生至成年身高和原始父母身高的测量值。
北欧人群的成年身高在 20 世纪 50 年代至 90 年代期间逐渐增加；女性身高每十年增加 6 毫米，挪威为 4 毫米；瑞典为 6 毫米；芬兰和丹麦为 7 毫米；男性身高每十年增加 9 毫米，在瑞典为 5 毫米；芬兰为 7 毫米；丹麦为 8 毫米；挪威为 15 毫米。这是由于儿童期的生长更多，尽管青春期中期的时间更早。20 世纪 20 年代至 60 年代出生的瑞典父母的身高每十年增加 11 毫米，母亲身高每十年增加 14 毫米。
北欧国家是世界上最高的人群之一，但成年身高仍继续显示出正向的长期变化，同时青春期提前也加快了生长速度，这突出表明需要定期更新国家身高参考值。
