Methods: Subjects included 701 elementary school students (351 boys and 350 girls) residing in Jeju. The research analyzed a sample and was carried out using the 24 hour recall method and one day consumption of total sugar. Results: The average daily total sugar intake was 55.3 g (male 53.1 g, female 57.6 g). Total sugar intake per meal was 6.3 g (11.4%) from breakfast, 6.9 g (12.5%) from lunch, and 7.2 g (13.0%) from dinner, 34.9 g (63.1%). Major food groups of total sugar were milks (17.04 g), grains and their products (12.79 g), fruits and their products (9.40 g), and sugars and sweets (7.30 g). In analysis of the amount of total sugar consumption from several recipes, much was taken in from dessert and snacks such as dairy products (15.08 g), bread and snacks (6.4 g), beverages (5.5 g), fruits (5.1 g), and ice cakes (4.8 g). Total sugar consumption was high for rices and side dishes such as noodles (5.1 g), stir-fried foods (2.3 g), fried foods (1.4 g), cooked rice with seasoning (1.4 g), and hard-boiled foods (1.1 g). In comparison of total sugar consumption for sugar sources, daily intake of natural sugar, added sugar, and natural and added sugar were 25.8 g, 23.3 g, and 6.2 g, respectively. High sugar intake group, which was over 20% of the energy from total sugar intakes, consumed significantly less Fe, Zn, and niacin than the low sugar intake group, which was below 20%. Conclusion: Total sugar intake of fifth graders of elementary schools on Jeju Island was 55.4 g/day, and it was usually intake from snacks. Therefore, elementary school students need nutritional education for proper selection of better snacks and for reduction of dietary sugar intake.

90 / 제주지역초등학생의당류섭취량 류하여식품군별섭취량을분석한결과초등학생의경우우유류에서 17.0 g으로가장높게나타났고, 곡류 (12.8 g), 과일류 (9.4 g), 당류 (7.3 g), 채소류 (4.6 g) 의순으로당섭취량이높게나타났다 (Table 5). Chung 24 의연구 (2001년국민건강영양조사자료분석 ) 에서는 1~99세전체연령에서과일 21.7 g (36%) 로부터가장많은당류를섭취하는것으로보고되었다. 1~19세의경우당류의주요급원식품은과일 18.7 g (33.4%) > 우유 8.1 g (14.5%) > 탄산음료 4.6 g (8.3%) > 쿠키 / 크래커 / 케이크 4.5 g (8.0%) > 사탕 / 젤리 / 꿀 / 엿 / 쵸콜렛 4.3 g (7.7%) > 채소 2.1 g (3.7%) 순으로섭취하였다. 이런결과와본연구결과로볼때대부분의학생들이주식인곡류를제외하고간식으로섭취하는과일류, 우유및유제품류, 음료류, 빵 과자류에서많은총당류를섭취하고있음을알수있다. 과일은당류뿐아니라비타민과무기질함량도높아과일섭취로인한당의과잉섭취는우려할필요가없는것으로본다. 24 그러나본조사대상자들의경우당류로부터많은양의당을섭취하고있었는데이는사탕 / 젤리 / 쵸콜렛등간식과음식조리시양념류에이용되는설탕 / 물엿 / 꿀등으로부터섭취되는양이다. 1일총당류섭취량에대하여조리법별로분류하여분석한결과주식류에서는면류 5.1 g, 일품요리류 1.4 g으로당류가높게섭취되고있었다. 초등학생의경우면류의음식섭취량은 21.0 g으로, 면류로부터얻어지는섭취열량은 58.4 kcal이었다. 부식류에서는초등학생은볶음류 2.3 g, 튀김류 1.4 g, 조림류 1.1 g, 구이류 0.9 g, 국류 0.8 g의순으로당섭취량이높게나타났다 (Table 6). 이것은기존의연구와비슷한결과이다. Park 등 27 은부식류중소스가포함된커틀릿등의튀김류 (1.63 g) 와조림류 (1.37 g), 볶음류 (1.28 g), 찜류 (0.80 g) 의순으로당섭취가많은조리법으로보고하였고, Kim과 Chung 13 은조리유형별당섭취량분석결과부식류에서는튀김류, 볶음류, 소스류, 조림류의순으로당섭취량이높았으며, 튀김류중에서는닭강정, 새우가스, 고구마맛탕, 탕수육등에서당함량이높았다고보고하였다. 부식류중튀김류에서는튀김과함께제공되는소스에의하여총당류섭취량이증가되고, 볶음류, 조림류, 무침류등의조리법에서는간장, 고추장, 설탕, 물엿, 꿀, 올리고당등의양념류의사용으로인한총당류함량의증가로음식섭취량에따라영향을미치는것으로여겨진다. 이러한점에서학교급식영양 ( 교 ) 사및조리사, 학부모대상으로당저감화교육을통하여음식조리시당의첨가량을조금씩줄여음식맛에는큰차이를주지않으면서당섭취량감소에는큰효과를얻도록하는방안을연구해야할것이다. 후식류에서는유제품류 (15.1 g) > 빵 과자류 (6.4 g) > 음료류 (5.5 g) 순으로높게나타났다 (Table 6). 조사대상이중고등학생이었던 Choi 등의연구에서, 가장많이섭취한간식은귤과과자류였다. 28 초등학생의경우학교급식에서간식으로우유가제공되기때문에유제품과이로인한유당섭취량이높은것으로보인다. 총당류섭취량을천연당, 첨가당, 혼합당으로분류하여섭취실태를분석한결과초등학생의경우 1일총당류섭취량 55.3 g 중천연당으로 25.8 g, 첨가당으로 23.3 g, 혼합당으로 6.2 g을섭취한것으로나타났다 (Table 7). 첨가당섭취량은주로당류, 음료류에서얻어지는것으로음식조리시양념류에이용되는설탕, 물엿, 꿀등의사용량과학생들이간식으로섭취하는빵과과자, 아이스크림, 음료등으로인한것으로여겨진다. 청소년을대상으로한 Kim 등 26 의연구결과간식을통한 1 일평균첨가당섭취량은 50.8 g이었다. 1일총열량섭취량대비간식별첨가당섭취에의한열량비율은아이스크림 (46.6%), 시리얼 (12.3%), 우유와두유를제외한음료수 (9.3%), 우유 (8.3%), 과자 / 과자 / 빵 ( 케이크 ) (6.4%) 의순으로나타났고, 간식으로섭취하는첨가당으로인한열량이총열량섭취량에대해차지하는비율은 1일평균 9.4% 로나타났으며, 일부대상자의경우 20~57% 의수준으로나타나, 조사대상청소년은첨가당섭취만으로도외국과우리나라의총당류섭취상한기준인 10~20% 수준을초과하는경우도있었다. 본연구결과로볼때, 우리나라초등학생은간식으로부터의첨가당섭취가총당류섭취량에크게영향을미치는것으로보인다. 그러나간식뿐만아니라가정식과외식조리에서양념으로이용되는설탕, 물엿, 꿀등의사용량이높아학생들을단맛에적응되어단맛을선호하는식습관으로유도되기쉽다. 따라서어린이스스로자신의설탕섭취량에관심을갖고설탕섭취량을낮추도록뒷받침해주는조리과학실험, 영양교육자료개발및영양교육실시등을위한국가, 식품산업체, 학교, 가정이공동관심과노력을시급히기울여야할것으로생각된다. 26 한국인영양섭취기준의총당류섭취기준에따라 1일총당류섭취량에대하여저, 중, 고등 3개의그룹으로나누어영양섭취실태를조사한결과, 총섭취열량에대해총당류섭취열량이 20% 이상인고당류섭취군이 10~20% 군과 10% 미만군보다열량, 지방, 탄수화물, 칼슘, 칼륨, 비타민 A, B 1, B 2, 비타민 C을유의적으로높게섭취하였다 (Table 8). 이는총당류섭취열량이높은군이상대적으로열량섭취량도높기때문인것으로보인다. 한편철분, 아연, 니아신과같은영양소의섭취는고당류섭취군이다른군에비해유의적으로낮아, 고당류섭취시이들미량영양소의불균형이초래될가능성이있음을보여주었다. 미국의학연구소의보고서 29 에의하면첨가당함량이높은식사를
Journal of Nutrition and Health (J Nutr Health) 2015; 48(1): 81 ~ 93 / 91 한사람들은칼슘, 마그네슘, 철, 아연, 비타민 A와비타민 E 등의필수영양소의섭취량이낮았으므로첨가당을총섭취열량의 25% 이상먹지말라고권고하였다. 한편국내연구에서는 Chung 등 30 의초등 5학년학생대상연구에서설탕을 100 g 이상으로먹는군 ( 설탕의에너지섭취비율 24.6%) 이 100 g 이하로먹은군보다열량, 탄수화물, 지방, 단백질, 칼슘, 비타민 C, 리보플라빈의섭취량이높아서본연구결과와비슷한경향을보였다. 따라서국내연구결과는미국인대상의연구와는다소다른결과를나타내는것으로보인다. 그러나고당류섭취군에서철, 아연, 니아신등주요필수영양소가유의적으로낮게섭취하는것으로나온것은주목할만한것으로서, 당함량이높은식품에이들영양소함량이낮을가능성이있으므로당섭취량이많은경우부족하지않도록주의해야할영양소인것으로보인다. 아이스크림, 과자, 초콜릿및사탕, 햄버거, 피자, 탄산음료와같은식품들의과도한섭취는지나치게높은당분과필요이상의열량섭취로비만뿐만아니라자극적입맛의습관화로인한편식을유발할수있으며, 31 성장및면역기능의약화, 만성빈혈등으로이어질수있어학업에도큰영향을미치게된다. 32 설탕의과잉섭취는충치를유발하고집중력결핍및충동적인행동을가져오는원인으로여겨지고있다. 33 또한첨가당의섭취증가는어린이에서비만, 2 당뇨, 3 심혈관계질환 4-6 위험을증가시킨다. 그러므로당류편식군학생들에게이들식품의섭취를줄이기위한적절한방안을구체적으로제시하여당저감화식품섭취패턴을생활화할수있도록영양교육을할필요가있다. 식생활습관설문지의문항중당식습관과관련한 5가지항목에응답한학생들을점수화하여달게먹는식습관점수가높은단맛선호군과낮은단맛저선호군의 2군으로나누어그룹별열량섭취량과총당류섭취량을분석한결과단맛선호군이단맛저선호군에비해열량, 탄수화물, 서당, 총당류섭취량이유의적으로높게나타났다 (Table 9). 따라서단맛선호군은실제당섭취량이높음을알수있었으며, 단맛선호가큰대상자에게당섭취관련영양교육을강화해야할필요가있는것으로사료된다. Yu 등 31 의연구에서조사대상자의식습관을살펴볼때, 전체적으로대조군보다당류편식군의식습관이바람직하지않은것으로나타났다. 세끼식사의규칙성, 아침식사여부, 식사시의알맞은양, 식사할때골고루먹기등에서남학생과여학생모두당류편식군의점수가유의하게낮으므로당류편식군학생들을대상으로골고루, 알맞게, 규칙적으로먹기와아침식사의중요성에대한영양교육이필요하다고보고하였다. 본연구결과를종합해보면제주지역초등학교 5학년학생들의 1일평균총당류섭취량은 55.4 g이었으며, 주로간 식을통해당섭취가이루어짐을알수있었다. 따라서초등학생의당섭취량통제를위해서는학생과학부모에게당저감화및올바른간식선택과섭취방법에대한영양교육이우선되어야할것으로사료된다. 또한식품업계에서도첨가당함량을낮추고아이들이간식을통하여식사에부족한영양소를섭취할수있도록영양간식을연구 개발할필요가있을것으로생각된다. 또한면류, 볶음류, 튀김류, 일품요리류, 무침류등의조리법에의해총당류섭취가증가되고있으므로집단급식소의영양 ( 교 ) 사및조리사를대상으로당류과다섭취에의한문제점을인식시키고당저감화조리법등을교육함으로써현장에서실천할수있도록국가, 식품산업체, 학교, 가정이공동관심과노력을하여야할것이다. 요약 본연구는제주지역초등학교 5학년학생 701명을대상으로 2009년 4월부터 6월까지 24시간회상법을이용하여 1 일식이조사를통한총당류섭취량을추정하였으며그결과는다음과같다. 1. 조사대상자의 1일열량섭취량은 1,629.8 kcal, 1일총당류섭취량은남학생 53.1 g, 여학생 57.6 g으로남녀평균 55.3 g이었다. 2. 끼니별 1일총당류섭취량은간식에서 34.9 g (63.1%) 으로가장많이섭취하였으며, 아침, 점심, 저녁식사에서섭취하는양은각각 6.3 g, 6.9 g, 7.2 g이었다. 3. 식품군별로는우유류 (17.04 g), 곡류 (12.79 g), 과일류 (9.40 g), 당류 (7.30 g) 에서섭취하는당함량이높았다. 4. 조리법별총당류섭취량은유제품류 (15.08 g), 빵 과자류 (6.4 g), 음료류 (5.5 g), 과일류 (5.1 g), 빙과류 (4.8 g) 의순이었고, 주식과부식류에서는면류 (5.1 g), 볶음류 (2.3 g), 튀김류 (1.4 g), 일품요리류 (1.4 g), 조림류 (1.1 g) 의순이었다. 후식류에서서당섭취량이높은음식은빵 과자류 (4.1 g, 6.4 g), 음료류 (2.5 g, 1.4 g), 빙과류 (3.4 g, 4.4 g) 이었다. 주식과부식류에서서당섭취량이높은음식은면류 (2.0 g, 4.1 g), 볶음류 (1.0 g, 1.1 g) 등이었다. 5. 1일총당류섭취량중천연당은 25.8 g, 첨가당은 23.3 g, 혼합당은 6.2 g으로 1일총당류섭취량의 42.1% 가첨가당에서섭취되었다. 6. 총열량섭취량중당류에서얻어지는열량비율이 20% 이상인고당류섭취군이 20% 미만저당류섭취군에비해철분, 아연, 니아신섭취가유의적으로더낮았다. 7. 단맛선호군은단맛저선호군보다열량, 탄수화물섭취량, 그리고총당류섭취량이유의적으로높았다.
92 / 제주지역초등학생의당류섭취량 이상의결과를종합해보면제주지역초등학교 5학년남녀학생들의총당류섭취량은 1일평균 55.4 g으로, 주로간식에서섭취하는비율이높았다. 따라서초등학생들의총당류섭취량통제를위해서는올바른간식선택과당저감화관련영양교육이필요하다고사료된다. References 1. Cho SH, Chung CE, Kim SH, Chung HK.
