Abstract

The aim of a school attendance policy (SAP) is to ensure breakfast time for school-aged adolescents. Therefore, this study investigated the effects of SAP on dietary behavior, particularly breakfast consumption, among adolescent middle school students (n=426) in the Ansan area of Gyeonggi-do. After implementation of the SAP, the response rates for eating breakfast every-day among boys (P>0.05) and girls (P<0.05) slightly increased by 44.6% and 35.8%, respectively, compared to before the SAP. Further, the degree of satisfaction with breakfast increased among both boys ('satisfied' and 'strongly satisfied'; 32.4% and 21.6%, respectively) (P<0.01) and girls ('satisfied' and 'strongly satisfied'; 32.8% and 14.2%, respectively) (P<0.001) compared to before the SAP. Moreover, boys (56.8%) and girls (53.9%) were aware that the SAP increased breakfast-eating frequency. Increases in deep sleep as a result of the SAP were high in both boys (39.2%) and girls (47.1%), and sleeping hours among boys (P<0.05) and girls (P<0.01) increased compared to before the SAP. The respondents were aware of the positive effects on physical function such as reduction of physical fatigue (boys 40.1%, girls 38.2%) and improvement of physical health (boys 36.5%, girls 32.8%). Thus, systematic and sustained political support at the national level is required to encourage healthy breakfast eating and physical activity in middle school students.

경기도 안산지역에 위치한 중학교에 재학 중인 2학년과 3학년 426명을 대상으로 9시 등교정책 실시에 따른 아침식사 섭취 빈도의 증가와 더불어 아침식사 관련인자, 간식, 수면 및 신체활동에 미치는 영향 및 이들의 인식도에 대해 조사한 후 결과를 요약하면 다음과 같다. 연구 대상자의 성별은 남학생이 222명(52.1%), 여학생이 204명(47.9%)이었으며 학년은 2학년 228명(53.5%), 3학년 198명(46.5%)이었다. 9시 등교정책 전 남학생의 약 39%가 '매일 식사를 했다'고 응답한 반면, 9시 등교정책 후에는 44.6%가 매일 아침식사를 하는 것으로 나타났다(P>0.05). 여학생 또한 9시 등교정책 후 정책 전의 32.4%에서 35.8%로 약간 상승하는 것으로 나타났다(P<0.05). 아침결식의 주된 이유는 9시 등교정책의 실시와 성별에 관계없이 '아침식사 시간의 부족', '입맛이 없어서'와 '늦게 일어나서'라는 응답 비율이 높은 것으로 나타났다. 간식 섭취 빈도는 9시 등교정책과 성별에 관계없이 '1~2회'가 가장 많았으나 9시 등교정책 전(P<0.05)과 후(P<0.05) 모두 '3~4회'와 '5회 이상'은 남학생에 비해 여학생의 간식 섭취 빈도가 많은 것으로 나타났다. 간식 섭취의 주된 이유는 9시 등교정책과 성별에 관계없이 '배가 고파서'라는 이유가 가장 많은 것으로 나타났다. 수면시간은 9시 등교정책 전과 후 모두 성별에 관계없이 '7~8시간'이라는 응답이 가장 많은 것으로 나타났으나 9시 등교정책 후 남학생과 여학생 모두 '8~9시간'의 응답 비율은 증가한 반면에 '7시간 미만'이라는 응답 비율은 감소하는 것으로 나타나 남학생(P<0.05)과 여학생(P<0.01) 모두 9시 등교정책의 실시로 인해 수면시간이 증가한 것으로 보인다. 그러나 9시 등교정책 전(P<0.001)과 후(P<0.01) 모두 남학생에 비해 여학생의 수면시간은 상대적으로 적은 것으로 나타났다. 일주일에 30분 이상의 운동을 하는 빈도를 조사한 결과 9시 등교정책 전 남학생은 '3~4회'가 27.5%로 가장 많은 반면, 여학생은 '0회'가 44.1%로 가장 많은 것으로 나타났다(P<0.001). 9시 등교정책 이후에도 남학생의 주당 운동 빈도는 여전히 '3~4회'가 28.4%로 가장 많은 반면, 여학생은 '1~2회'가 36.3%로 가장 많은 것으로 나타나 9시 등교정책 후에도 여전히 여학생에 비해 남학생의 운동 빈도가 상대적으로 많은 것으로 나타났다(P<0.001). 9시 등교정책에 대한 인식도를 조사한 결과 9시 등교정책이 아침식사 섭취 빈도를 증가시킨 것으로 인식한 남학생은 56.8%, 여학생은 53.9%였다. 숙면을 취하는 데 영향을 주었다고 인식한 남학생은 39.2%, 여학생은 47.1%였으며 신체적인 피로도의 감소(남학생 40.1%, 여학생 38.2%) 및 신체적인 건강의 향상(남학생 36.5%, 여학생 32.8%)에도 기여한 것으로 인식하고 있었다. 본 연구 결과 안산지역 중학생들은 9시 등교정책이 아침식사 섭취 빈도의 증가, 숙면 및 신체적인 기능을 향상시키는 데 긍정적인 영향을 준 것으로 인식하는 것으로 나타났다. 따라서 9시 등교정책이 중학생들의 규칙적인 아침식사를 통한 깊은 수면의 유도 및 바람직한 신체활동을 통한 건강한 학교생활이 지속될 수 있도록 학교와의 지속적인 협력 및 연계를 통한 국가차원의 정책적인 지원이 요구된다.
