مؤشر كتلة الجسم | BODY MASS INDEX (BMI)

ما هو مؤشر كتلة الجسم؟

عبارة عن قيمة أو مقياس يُحسب من خلال تقسيم وزن شخص ما على مربع طوله، ويتم التعبير عن الناتج بواحدة كيلوغرام على متر مربع (Kg/m2).

يُستخدم مؤشر كتلة الجسم لمعرفة مدى رشاقة الشخص وتناسب وزنه مع طوله. ويرتبط في معظم الحالات مع كمية الدهون الإجمالية في الجسم، أي أن زيادة قيمته تعني زيادة كمية الدهون. وأهم ما يميز هذا المؤشر أنه يأخذ بعين الاعتبار التنوعات الطبيعية في شكل الجسم، وذلك من خلال التقييم على أساسات مجالات كما يلي:

  1. قيمة المؤشر أدنى من 18.5 (Kg/m2): نقص وزن.
  2. قيمة المؤشر بين 18.5 و25: وزن طبيعي أو صحي.
  3. قيمة المؤشر بين 25 و30: زيادة وزن.
  4. قيمة المؤشر أعلى من 30: بدانة.

وضع عالم الفلك والرياضيات والإحصاء البلجيكي أدولف كوتلي أساسيات مؤشر كتلة الجسم في الفترة ما بين 1830 و1850 أثناء تطويره لما أطلق عليه "الفيزياء الاجتماعية". لكن المصطلح الحديث المُستخدم اليوم تمت صياغته لأول مرة عام 1972 في ورقة بحثية ألفها الطبيب الأمريكي أنسل كيز وآخرون.
