Objective-To assess the influence of a specific dietary pattern on overall survival.Design-Cohort study. Setting-Three rural Greek villages, the data from which were collected as part of an international cross cultural study offood habits in later life.

Malnutrition is caused either by cancer itself or by its treatment, and affects the clinical outcome, the quality of life (QOL), and the overall survival (OS) of the patient. However, malnutrition in children with cancer should not be accepted or tolerated as an inevitable procedure at any stage of the disease. A review of the international literature from 2014 to 2019 was performed. Despite the difficulty of accurately assessing the prevalence of malnutrition, poor nutritional status has adverse effects from diagnosis to subsequent survival. Nutritional status (NS) at diagnosis relates to undernutrition, while correlations with clinical outcome are still unclear. Malnutrition adversely affects health-related quality of life (HRQOL) in children with cancer and collective evidence constantly shows poor nutritional quality in childhood cancer survivors (CCSs). Nutritional assessment and early intervention in pediatric cancer patients could minimize the side effects of treatment, improve their survival, and reduce the risk of nutritional morbidity with a positive impact on QOL, in view of the potentially manageable nature of this risk factor.

In 1988 and 1989, we investigated in three Greek villages the dietary patterns of 182 men and women aged > 70 y by using a validated semiquantitative food-frequency questionnaire and compared these dietary patterns with the traditional Greek diet as ascertained in the late 1950s by Keys and his colleagues. As in the traditional diet, olive oil dominated fat intake, total fat exceeded 35% of total energy intake, average daily consumption of fruits and vegetables exceeded 500 g, and average ethanol intake for men corresponded to two to three glasses of wine per day. In contrast, consumption of meat and meat products has substantially increased and intake of bread and other cereals has apparently declined. We observed no differences between the two periods with respect to consumption of legumes, eggs and egg products, and sugar confectionery. We have also attempted to assess whether a gradient of adherence to the traditional Greek diet can be identified in the diets of the study subjects, and whether it can subsequently predict total mortality. During a follow-up period of approximately 5 y, 53 deaths were observed. The risk of death was apparently higher among the minority of study subjects whose diet deviated substantially from the traditional Greek pattern, compared with the majority whose diet adhered closely to the traditional pattern.

Aim: To assess breastfeeding practices, focusing on the prevalence and the determinants of exclusive breastfeeding during hospital stay. Methods: A cross‐sectional study of 1603 healthy women, who delivered healthy infants weighing more than 2500 g, was conducted in the area of Athens, Greece. Participants completed a self‐administered questionnaire on the day they were discharged from the maternity ward. Classification of breastfeeding and recall period from birth to discharge were in accordance with the WHO criteria. Hierarchical logistic regression analysis was used to study determinants of exclusive breastfeeding initiation. Results: Breastfeeding initiation was reported by 96.1% of the participants. However, exclusive breastfeeding was initiated only in 19.1% and predominant breastfeeding in 7.2% of the cases. The univariate analysis showed that maternal younger age, low educational level, unemployment, vaginal delivery, infant birthweight >3000 g, multiparity, early initiation of breastfeeding, rooming‐in and awareness on the existence of breastfeeding centres were associated with higher rates of exclusive breastfeeding. Logistic regression analysis revealed that rooming‐in (OR 3.72, p<0.01), demand feeding (OR 2.18, p<0.01), type of delivery (OR 1.61, p<0.01) and the source of information received about breastfeeding are more important determinants of exclusive breastfeeding than the socio‐demographic parameters. Conclusions: Exclusive breastfeeding during hospital stay in the area of Athens is low. Demand feeding and rooming‐in positively influence exclusive breastfeeding initiation, while caesarean section and information by mass media have a negative impact.

This study suggested that whole grain consumption more than 7 times/week was consistently associated with reduced risk of breast cancer.
