Background: overweight and obesity are a global epidemic, with rates risen to alarming levels in most countries. Chile is no exception, with sharp increases in obesity prevalence, especially among school-age children, affecting almost 40% of six-year-old children. In this context, the Ministry of Health (MoH) has decided to develop a ‘National Plan...

While some of our countries are still facing nutrition deficiencies (stunting/short stature and micronutrient deficiencies), overweight and obesity are increasing in an alarming way. In addition, a very limited research network and lack of funding make it extremely challenging to foster collaborative efforts to address the complex nutritional probl...

Previous research in Latin America shows that socioeconomic status (SES) influences dietary patterns and obesity distribution. However, it is unclear how SES impacts overall nutrition status, in a post-transitional country such as Chile. The objective of this study was to assess the relationship between nutritional status (overweight, short stature...

The objective of this study was to assess the relationship between nutritional status (overweight, short stature and anemia), and two key aspects of the socio-economic status (SES), monthly income and educational level, in adult Chilean population.

Background: In the 2007 World Cancer Research Fund/American Institute for Cancer Research Second Expert Report, the expert panel judged that there was strong evidence that alcoholic drinks and body fatness increased esophageal cancer risk, whereas fruits and vegetables probably decreased its risk. The judgments were mainly based on case-control st...

Purpose: The 2007 World Cancer Research Fund/American Institute for Cancer Research expert report concluded that foods containing vitamin C probably protect against esophageal cancer and fruits probably protect against gastric cancer. Most of the previous evidence was from case-control studies, which may be affected by recall and selection biases....

El cáncer de vesícula biliar es la neoplasia maligna más común en el tracto biliar. Chile presenta la tercera prevalencia más alta de cáncer de vesícula en el continente americano, siendo las mujeres chilenas de la ciudad de Valdivia las que presentan la prevalencia más alta.Los principales factores que se han asociado al cáncer de vesícula son: se...

Carotenoids and retinol are considered biomarkers of fruits and vegetables intake and are of much interest because of their anti-inflammatory and anti-oxidant properties; however, there is inconsistent evidence regarding their protective effects against lung cancer. We conducted a meta-analysis of prospective studies of blood concentrations of caro...

Background: Lung cancer is the most common cause of cancer death. Fruits and vegetables containing carotenoids and other antioxidants have been hypothesized to decrease lung cancer risk. As part of the WCRF International Continuous Update Project, we conducted a systematic review and meta-analysis of prospective studies. Methods: We searched Pub...

Background: Greater body mass index (BMI) has been convincingly related to increased endometrial cancer risk, however, whether adiposity earlier in life or abdominal fatness is an independent risk factor and whether weight gain or greater height increases the risk is not clear. Methods: As part of the Continuous Update Project of the World Cance...

Smoking is estimated to cause about half of all bladder cancer cases. Case-control studies have provided evidence of an inverse association between fruit and vegetable intake and bladder cancer risk. As part of the World Cancer Research/American Institute for Cancer Research Continuous Update Project, we conducted a systematic review and meta-analy...

High versus low intake of fruit, vegetable, legume, and cereal fibre and risk of colorectal cancer

In the World Cancer Research Fund/American Institute for Cancer Research report from 2007 the evidence relating body fatness to ovarian cancer risk was considered inconclusive, while the evidence supported a probably causal relationship between adult attained height and increased risk. Several additional cohort studies have since been published, an...

Background: Current evidence indicates that red and processed meat intake increases the risk of colorectal cancer; however, the association with colorectal adenomas is unclear. Objective: To conduct a systematic review and meta-analysis of epidemiological studies of red and processed meat intake and risk of colorectal adenomas as part of the Con...

Measurement errors in the dietary assessment of fruit and vegetable intake may attenuate associations with breast cancer risk and might explain the weak associations observed in epidemiologic studies. Carotenoid concentrations in blood are biomarkers of fruit and vegetable intake; however, no systematic assessment has compared dietary intake with b...

Evidence for an association between fruit and vegetable intake and breast cancer risk is inconclusive. To clarify the association, we conducted a systematic review and meta-analysis of the evidence from prospective studies. We searched PubMed for prospective studies of fruit and vegetable intake and breast cancer risk until April 30, 2011. We inclu...
