Because the rates of spontaneous and iatrogenic delivery prior to 36 weeks are higher among twins than among singletons, singleton fetuses surviving to 36 weeks are likely different from twins surviving to 36 weeks (especially at both extremes of birth weight).
A fair agreement between underweight/fat and normal and a moderate agreement between both the extremes of weight (underweight vs overweight) was seen.
Providing alerts to address both extremes of the possible weight continuum addresses this issue but has its own challenges.
Firstly we aimed to determine if both extremes of inter-pregnancy weight change influenced the risk of a range of pregnancy outcomes, including SGA births, in a relatively small cohort of women delivering at a single maternity unit in the UK.
Various conditions can cause premature birth, including infections, drug and alcohol use, extremes of weight or age in the mother and carrying more than one fetus.
Although numerous studies have linked extremes of weight with poor outcome in adult intensive care patients, the effect of weight on intensive care outcome has not previously been reported in the pediatric population.
The evidence of any adverse effects from diet in pregnancy was usually from observational studies on extremes of weight reduction diets or those on intake of food with a very high or low glycaemic index.
We postulate that this increased provision of calories and protein may translate into improved clinical outcomes, particularly for the patients at the extremes of weight, but the current study is not powered to demonstrate such a difference.
Second, it is important to note that individuals with comorbid psychiatric disorders, extremes of weight, or major neurological and cardiovascular conditions were excluded from the clinical trials, and all patients were in generally good health.
When designing the Ghanaian figural stimuli, the models were created on a computerized interval scale rather than an ordinal scale and we also included models that represented the far extremes of weight from cachexia to morbidly obesity.
