  1. Nutritional Evaluation and Anthropometry Professor Jin BQ Department of Food Science & Nutrition NJNU

  2. Nutritional Status1(Human Physiological Status)

  3. Nutritional Status2 • Physics/Physiology • Mentality/Psychology • Influent on the dietary behavior or eating custom, • according to their religion, ethnic, culture & economics

  4. 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

  5. Objectives • Suggestion or Advice for our Government • Scientific or Reasonable Opinion for People

  6. Content Nutrition Status with Health Level Life Expenditure Nutritional Deficiency Metabolic Diseases

  7. Methods • Nutritional Survey • Anthropometry (3d) • Biochemical Test/Blood or Serum

  8. 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

  9. 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

  30. 3 Lung vital capacity FLJ-A浮标式肺活量计

  31. 受试者夹鼻，在一次平静吸气之末，继续做一次最大限度的吸气。三通阀门与肺量计相通，描记3～4次呼吸曲线。根据呼吸曲线变化的高度，计算出潮气量、补吸气量、补呼气量和肺活量受试者夹鼻，在一次平静吸气之末，继续做一次最大限度的吸气。三通阀门与肺量计相通，描记3～4次呼吸曲线。根据呼吸曲线变化的高度，计算出潮气量、补吸气量、补呼气量和肺活量

  32. Nutritional Biochemical Analyse • In Blood • In Urine • In Hair

  33. 测量仪器校正 • 身高、坐高：皮尺/钢尺从基准线校正 10.0±0.1cm 立柱垂直度、连接处吻合度 • 体重：如果是电子称，需校零 10.0±0.1kg

  34. 皮褶厚度计：指针回零; < ±0.1mm • 握力计：指针回零; < ±0.1kg • 血压计：水银柱开关、水银柱、气球、覆带 • 体围：无弹性皮尺/卷尺；< ±0.1cm

  35. 测量参数-标准化、准确度 • 标准化：同一指标-部位---连续测量 2-3次 求：平均值 • 准确度：平均误差 < 5%

  36. 测量要求 • 裸露测量部位 • 保持正确测量姿势 • 体重：空腹、尽量减少衣着

  37. Trial Design & Data Treatment 1 Trial Design 1.1 Random 1.2 Partnership: age, sex, weight (beginning/end ) • One way • Latin Square: 2 × 2; 2 × 3; 3 × 3; 3 × 4…..
