목적: 본 연구는 한국 어린이를 대상으로 안축장과 신체 계측치와의 관련성을 조사하였다. 방법: 서울지역에서 11-12세(평균 연령: $11.95{\pm}0.22$세, 여학생: 45.0%)의 초등학생 40명을 대상으로 하였다. 부분 간섭측정법에 의한 안축장, 각막 곡률반경, 굴절이상도, 신장(m), 그리고 체중(kg)을 측정하였고, 체질량지수(BMI $[kg/m^2]=weight/[height]^2$)와 비만정도지수(DO[%]=[actual weightstandard weight]/standard weight)는 계산하였다. 근업 활동으로 1일 평균 독서시간, TV 시청시간, 그리고 컴퓨터 사용시간에 대하여 설문하였다. 결과: 전체 대상자의 평균 굴절이상도는 $1.06{\pm}0.84D$였고, 이들의 안축장과 몸무게(r=0.427, p=0.006), 체질량지수(r=0.508, p=0.001), 비만정도지수(r=0.371, p=0.018)는 유의한 양의 상관관계를 보였다. 또한 안축장은 체중(p=0.041)과 체질량지수(p=0.015)의 1사분위수, 그리고 비만정도지수가 가장 높은 그룹(p=0.042)에서 유의하게 길었다. 연령, 성별, 그리고 근업 활동을 보정한 후에 다중회귀분석에서 체중, 체질량지수 그리고 비만정도지수는 안축장과 유의한 관련성을 보였고, 특히, 근업 활동에서 1일 독서시간은 안축장과 유의한 관련성을 보였다. 결론: 한국 초등학생의 안축장은 체중과 관련이 있었다. 특히, 긴 안축장과 1일 독서시간은 유의한 관계를 보였다.

Abstract ▼ AI-Helper

Purpose: To investigate the relationship between axial length (AL) and anthropometric parameters in Korean children. Methods: This study included 40 urban school children aged 11-12 years (mean age, $11.95{\pm}0.22$ years; 45.0% girls) residing in Seoul, South Korea. AL (using partial coherence laser interferometry), corneal radius, refractive error, height (m), and weight (kg) were measured. Body mass index (BMI $[kg/m^2]=weight/[height]^2$) and degree of obesity (DO[%]=[actual weight standard weight]/standard weight) were calculated. Furthermore, the number of hours spent reading, watching television, and using a computer every day was determined using a detailed questionnaire. Results: The students had a mean spherical equivalent refraction of $1.06{\pm}0.84$ D. Weight (r=0.427, p=0.006), BMI (r=0.508, p=0.001), and DO (r=0.371, p=0.018) showed a significant positive correlation with AL. Furthermore, longer AL was significantly associated with heavier weight (p=0.041), and higher BMI (p=0.015), and higher DO quartiles (p=0.042). After adjust for age, sex, and near-work activities, multivariate linear regression models showed that weight, BMI, and DO were still significantly associated with AL. Among the near-work activities, daily reading time was significantly associated with AL. Conclusions: AL was positively related to weight as well as daily reading time in Korean urban school children.

문제 정의

Therefore, the purpose of this study was to assess the relationships of AL with anthropometric parameters after adjusting for near-work activities in Korean elementary school children.

대상 데이터

Moreover, despite the very high prevalence of myopia in South Korea, the association of AL with anthropometric parameters in Korean children has not been investigated. In this study, the relationships between AL and height, weight, BMI, DO, and near-work activities were examined in Korean school children aged 11-12 years. The results showed that after adjustment for near-work activity, heavier students were significantly associated with the longer AL.
This study included 40 volunteer urban school children aged 11-12 years (mean age, 11.95±0.22 years; 45.0% girls) in Seoul, South Korea.

데이터처리

The spearman correlation analysis was used to evaluate the correlations between AL and the anthropometric parameters. Multivariate linear regression analysis was performed to determine the associations of AL with the anthropometric parameters and near-work activities. The results are expressed as the mean±standard deviation (SD) of five repeated measurements.
The Kruskal-Wallis test was performed to analyze the variations in AL according to quartiles of the anthropometric parameters. The spearman correlation analysis was used to evaluate the correlations between AL and the anthropometric parameters. Multivariate linear regression analysis was performed to determine the associations of AL with the anthropometric parameters and near-work activities.

이론/모형

The Mann Whitney test was also used to compare the data between boys and girls. The Kruskal-Wallis test was performed to analyze the variations in AL according to quartiles of the anthropometric parameters. The spearman correlation analysis was used to evaluate the correlations between AL and the anthropometric parameters.
000, Mann-Whitney test), only the right eyes were analyzed. The Mann Whitney test was also used to compare the data between boys and girls. The Kruskal-Wallis test was performed to analyze the variations in AL according to quartiles of the anthropometric parameters.

성능/효과

In conclusion, heavier Korean children tend to have longer ALs. Furthermore, daily reading time is strongly associated with AL.
In the students, who were aged 11 to 12 years, the mean height, weight, BMI, and DO were 1.49±0.07 m, 41.79±7.68 kg, 18.63±2.42 kg/m2, and 6.02±16.83%, respectively (Table 1).
