- 研究生活环境 (加纳农村,加纳城市,欧洲) 对饮食可持续性的影响.
- 确定加纳人口对饮食可持续性的因素.
主要方法:
- 利用了来自非洲移民研究中的肥胖和糖尿病研究的横截面数据 (N=3169,年龄25-70岁).
- 开发了SDI (0-16分) 使用饮食质量指数-国际,与食品相关的温室气体排放,天然与加工食品的比例,以及食品支出.
- 使用线性回归来比较研究地点的平均SDI,调整社会人口统计学和生活方式因素.
主要成果:

Assessment of the Gastrointestinal System II: Health Perception Pattern
81
Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health Perception Patterns
Health perception patterns offer valuable insights into a patient's lifestyle habits and how they may impact their GI health. These patterns include:

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
323
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
