Purpose: This study examined the relationships among serum ferritin, vitamin D, folate, iron, and vitamin B12 as indicators of obesity. The results provide the basic data for the prevention and treatment of obese and severely obese people. Methods: This study selected 44 people from 18 years of age ...

체질량지수 30.0 kg/m2 이상인 고도비만 유병률의 증가추이는 어떠한가? | 체질량지수 (body mass index, BMI) 30.0 kg/m2 이상인 고도비만 유병률은 2006년 2.8%, 2016년 5.5%로 10년 동안 약 2배 증가한 것으로 분석되고 있다 [3]. 비만할수록 지방조직이 증가하고 지방조직에서 분비되는 leptin, visfatin과 같은 아디포카인의 혈중 수치가 높을 경우 염증반응 및 인슐린 저항성 등을 유도하여 제 2형 당뇨병 및 동맥 경화로 발전된다고 보고된다 [4]. | |
비타민 D의 역할은 무엇인가? | 비타민 D는 체내 골격의 형성과 유지, 칼슘 대사의 항상성 유지에 필수적인 역할을 하며, 전 세계적으로 현대인에게 결핍이 우려되는 영양소이다 [13]. 국내에서도 비타민 D의 수준이 매우 낮으며 남성보다는 여성이, 연령대로는 20대가 가장 낮은 것으로 보고되었다 [14]. | |
혈중 비타민 D 농도는 25(OH)D3 수준을 통해 판정하는데 세계보건기구에서는 어떠한 경우 결핍으로 판정하는가? | 혈중 비타민 D 농도는 25(OH)D3 수준을 통해 영양상태를 판정하고 미국의학협회에서 혈중 25(OH)D3 수준이 20 ng/mL 이상일 때 비타민 D 충분, 20 ng/mL (50 nmol/L) 미만일 때를 비타민 D 불충분으로 정의한다 [17]. 세계보건기구에서는 혈중 25(OH)D3 수준이 10 ng/mL 이하인 경우 결핍으로 판정하며 국내에서는 결핍기준이 정해지지 않았다 [18]. 비만한 성인 일수록 감소되어 있는 역의 상관관계로 보고되었으나 [19], 최근 체질량지수 25 이상의 비만인이 정상인에 비하여 비타민 D 수치가 높아 양의 상관관계 나타낸다고 보고한 국내 연구가 존재한다 [20]. |
