Abstract

BACKGROUND

The aim of this study was to determine the prevalence of refractive errors among young and middle-aged adults in Norway.

MATERIAL AND METHODS

Refractive errors were measured with an autorefractor in a population-based sample of young (20-25 years) and middle-aged (40-45 years) adults participating in a health study (HUNT) conducted in Nord-Trøndelag county in Norway in 1996-97.

RESULTS

A total of 3137 persons (1248 young and 1889 middle-aged adults) with corrected visual acuity >0.5 (in either eye) were included. About half of the population (51.8% among the young and 52.3% among the middle-aged adults) were emmetropic. The prevalence of myopia was 35.0% in the young adult group and 30.3% in the middle-aged group. Myopia was significantly higher in women aged 20-25 years (36.4%) than in men aged 40-45 years (28.1%). Prevalence of hyperopia increased with age from 13.2% (20-25 years) to 17.4% (40-45 years).

INTERPRETATION

The results show a relative high prevalence of myopia in the general population of Norway.

摘要

背景

本研究旨在确定挪威中青年人群屈光不正的患病率。

材料与方法

在1996 - 1997年于挪威北特伦德拉格郡开展的一项健康研究（HUNT）中，对年轻（20 - 25岁）和中年（40 - 45岁）成年人的基于人群的样本，使用自动验光仪测量屈光不正情况。

结果

总共纳入了3137人（1248名年轻人和1889名中年人），其矫正视力>0.5（任何一只眼睛）。大约一半的人群（年轻人中为51.8%，中年人中为52.3%）为正视眼。年轻人群近视患病率为35.0%，中年人群为30.3%。20 - 25岁女性的近视率（36.4%）显著高于40 - 45岁男性（28.1%）。远视患病率随年龄增长从13.2%（20 - 25岁）升至17.4%（40 - 45岁）。
