概括
在孕妇的干预措施中,在营养之前引入运动有效地减轻了怀孕后期过度体重增加. 同时或顺序的营养和运动显示了类似的早期结果,但顺序对后来的结果很重要.
科学领域:
- 产科和妇科 产科和妇科
- 营养科学 营养科学
- 运动生理学 运动生理学
背景情况:
- 过度的妊娠体重增加 (EGWG) 是怀孕期间的一个重大问题,与不利的母亲和婴儿结局有关.
- 结合营养和运动的行为干预是管理怀孕期间体重增加的常见策略.
- 这些干预措施中营养和运动组件的最佳时间和顺序尚不清楚.
研究的目的:
- 为了比较顺序与同时引入营养和运动干预措施的有效性.
- 评估不同干预序列对预防早期和晚期过度妊娠体重增加 (EGWG) 的影响.
主要方法:
- 一个平行组随机试验,涉及84名健康的孕妇 (平均年龄32.4岁,BMI 26.0 kg/m2).
- 参与者被分配到三个组:同时营养和运动 (NE),营养首先然后运动 (N+E),或运动首先然后营养 (E+N).
- 从基线 (12-18周的GA) 监测到25周的GA (中点),然后到36周的GA.
主要成果:
- 在NE,N+E和E+N组之间没有观察到早期EGWG (基线至25周) 的显著差异.
- 从第25周到第36周,N+E组的体重增加 (2.9±2.3公斤) 与NE (2.5±1.7公斤) 和E+N (1.6±1.3公斤) 相比显著增加.
- 与NE和E+N组相比,N+E组的参与者在中期后的体重增加过多.
结论:
- 虽然早期的妊娠体重增加不受序列的影响,但后来的结果受到干预组件顺序的影响.
- 首先引入运动,其次是营养 (E+N) 或持续的联合干预 (NE) 与营养优先 (N+E) 相比,有效地缓解了晚期EGWG.
- 干预的顺序,特别是在营养之前优先考虑运动,可以增强坚持并改善管理妊娠体重增加的结果.

Diabetes Mellitus: Type 2 and Gestational
2.1K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding
48
Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

Bulimia Nervosa

Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...

Pathophysiology of Diabetes
820
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
