Nutritional Evaluation and Anthropometry Professor Jin BQ Department of Food Science & Nutrition NJNU
Nutritional Status2 • Physics/Physiology • Mentality/Psychology • Influent on the dietary behavior or eating custom, • according to their religion, ethnic, culture & economics
Nutritional Survey & Surveillance • Collecting Data from Family and Community in Investigation • Learning information in the society, such as lifestyle, eating hobbit, ethnic, religion, economic level, culture and social background…… • Surveying the change, development and transaction
Objectives • Suggestion or Advice for our Government • Scientific or Reasonable Opinion for People
Content Nutrition Status with Health Level Life Expenditure Nutritional Deficiency Metabolic Diseases
Methods • Nutritional Survey • Anthropometry (3d) • Biochemical Test/Blood or Serum
Parameter of Anthropometry • Body Weight & Height (P201) • Broca (WB) = BH (cm)-100 (P201) • Body Mass Index for weight judgment(202) BMI = BW(kg)/ BH(m)2 (202) • Arm Circle (202) • Skinfold (202) • Body Density (P 203) • Body Fat (%)=[(4.95/D)-4.50] ×100% ) (P 203) • Grip
Parameters & Corrective • 身高、坐高 10.0 cm±0.1cm • 体重 10.0kg±0.1kg • 标准体重 Broca (WB) = BH (cm)-100/105 • 体质指数BMI = BW(kg)/ BH(m)2 • 头围,上臂围,胸围,腰围,臀围 1.0 cm±0.1cm • 皮褶厚度 1.0 mm±0.1mm • 体脂含量 BF%=[(4.95÷D) - 4.50] ×100% • 握力 1.0kg±0.1kg
