Salivary cortisol is a steroid hormone that is produced in the hypothalamic-pituitary-adrenal axis and secreted into saliva when persons are under stress. High levels of cortisol in saliva can be produced by many different factors, including obesity and certain psychological disorders. The articles selected for inclusion in this review were identified using Google Scholar and Medline, and this search obtained a total of 57 items. The validity of these studies was established according to the degree of evidence presented, by citations and by their applicability to the healthcare context in Spain. Specifically, this review takes into consideration studies of salivary cortisol and stress in children and adults, and those examining the relation between high levels of salivary cortisol and other disorders such as anxiety, attention-deficit/hyperactivity disorder, social phobia or emotional deprivation. These studies show that salivary cortisol is a clear indicator of stress in both children and adults. High levels of this hormone in saliva are associated with the following main consequences: reduced immune function, affecting healing and thus prolonging recovery time; delayed growth in children; increased blood pressure and heart rate in both children and adults.

Background: Breastfeeding is a recommended practice from national and international institutions due to the health benefits that it provides, both for the nursling and for the mother. Nowadays, overweight and obesity result in greater morbidity along different life periods. Objective: The goal of this systematic review is to explore the characteristics of breastfeeding in the prevention of overweight and obesity during childhood. Method: A systematic search has been carried out and 113 papers have been selected: 20 meta-analysis and reviews, 6 original papers of clinical trials, 42 cohort or longitudinal studies, 19 correlational studies, 24 descriptive studies and 2 books. Results: According to the analysed papers, there is a causal relationship between breastfeeding and the prevention of childhood obesity. Discussion/conclusion: In the various studies explored, it has been observed that the maximum benefits of breastfeeding are obtained when its duration is longer than 6 months and when it extends for two years, complemented with other foodstuffs. Other studies show that breastfeeding is effective in obesity prevention, even when its duration is limited. It is also important that complementary foods are introduced after the first six months of age, so as to reduce food allergy risk and to prevent obesity. Similarly, the weight of the mother during pregnancy has been associated with childhood obesity, as well as the weight of the child when he was born and other factors like maternal smoking and socioeconomic status. © 2015, Grupo Aula Medica S.A.

Overweight, obesity, and breast cancer are three pathologies that are endemic in the world today and which have a great impact on society. Many research studies are currently trying to discover possible associations between these factors and to specify the links between them. Objective: To verify whether there is a direct connection between overweight/obesity in women with breast cancer and its relation to age of diagnosis. Materials and methods: The sample population in this study was composed of 118 women (32-76 years of age) who had been diagnosed and treated for breast cancer in 2009-2011 at the Centro Oncológico Estatal ISSEMyM [National Cancer Institute of Mexico]. An observational, descriptive, and transversal study was performed in which a random sample of n = 60 women was divided into two groups. The first group was composed of women with breast cancer, but who were of normal weight. The second group was composed of women with breast cancer, but who were either overweight or obese. In both groups, the Patient-Generated Subjective Global Assessment (PG-SGA) was applied, and the BMI (weight and height) was determined as well as waist circumference. Results: A statistically significant relation was found between age of diagnosis and weight (normal/overweight/obese) of the subjects (p < 0.05). Conclusions: The results obtained show that overweight and obesity are directly linked to breast cancer and age of diagnosis. Breast cancer was diagnosed earlier in women of normal weight.

Spain has become the country in the European Union with the fourth highest number of overweight and obese children. This condition directly affects physical health as well as mental health. The objective of this research study was to evaluate motivational aspects in one group of obese or overweight adolescents and another group of normal-weight adolescents. For this purpose a descriptive observational study was carried out in an educational institution in Guadix (Granada). The universe was composed of 200 children of ages 10 to 14. A sample of 24 children was selected by means of proportional random sampling with an error of 0.19, and was divided into the following groups (i) 12 normal-weight children; (ii) 12 obese children. Motivation was measured by means of the School Motivation Analysis Test (SMAT), a multidimensional measuring instrument based on Cattell's dynamic model of motivation and emotions. Our study evaluated five motivational parameters: TAO (total autism-optimism), TGI (total general information), TIN (total integration), TPI (total personal interest), and TCO (total conflict). Our results showed that for each of the SMAT variables, the overweight and obese children obtained an average value of 4.5 in contrast to the normal-weight children, who obtained an average value of 5.9. This indicates that overweight and obese children have low motivational states and a higher level of frustration. They also tend to distort reality by alleging the existence of obstacles that prevent them from achieving their goals.

Obesity and breast cancer are two very frequent pathologies in the world today, which have a strong impact on society. Various research studies have tried linking the two. For this purpose, data was collected from the medical histories of 524 women who had been diagnosed and treated for breast cancer from January 2009 to September 2010. The objectives of the study were to find and verify a possible association between the nutritional state of these women and their age when they were diagnosed with the tumour (p < 0.0001) as well as a statistically significant association (p < 0.0001) between the age of the first menstruation and the nutritional state of the patients. The results obtained showed that obesity was closely related to breast cancer.

Many studies have analyzed the possible association between the development of obesity and hormone levels, as well as their relation with the early development of breast cancer. As part of this study, we performed a retrospective collection of data from the clinical histories of 524 women in Granada (Spain), who had been diagnosed with breast cancer. The objectives were to verify an association between the nutritional state of the women and their age at breast cancer diagnosis as well as a possible relation between their nutritional state and seric levels of estrogens. The results obtained in this study show that obesity and the levels of certain hormones, such as estrogens, are closely associated with the early development of breast cancer.

Recent studies show an alarming increase in the rate of overweight / obesity among the infant - juvenile population. Obesity in childhood is associated with a significant number of complications, such as sleep apnea syndrome, insulin resistance and type 2 diabetes, hypertension, cardiovascular disease and some cancers. It is estimated that the prevalence of sleep apnea in children is 2-3% in the general population, while in obese adolescents, varies between 13% and 66%, according to various studies. It is associated with impairment of neurocognitive function, behavior, cardiovascular system, metabolic disorders and growth. Sleep apnea is a serious public health problem that increases when children and adolescents are overweight or obese. We hypothesize that aerobic endurance exercise can be an effective treatment for obesity and apnea at the same time. The aim of this study was to determine the influence of physical activity in children and adolescents with overweight / obesity in sleep apnea. An observational, descriptive, prospective, longitudinal study will be carried out in children with sleep apnea and obesity. The universe will be made up of 60 children and adolescents aged between 10 and 18 years, attending the endocrinology service for suffering of obesity in the Hospital Clinico San Cecilio of Granada during the period September 2012-September 2013. The smple will consist of children and adolescents that meet these characteristics and to whom their parents/tutors have authorized through the informed consent. Sleep apnea in children wil be measured by polysomnography and sleep quality questionnaire. There will also be a nutritional assessment by a food frequency questionnaire and an anthropometric assessment. Among the expected results are the lower overweight and obesity in children through the physical activity program. To reduce apnea and to improve sleep quality.

In addition to its important role in the initiation of breastfeeding, early skin-to-skin contact benefits both mothers and their babies. Objective: To inform all mothers of premature babies about the importance of skin-to-skin contact and breastfeeding in order to foment a closer bond between mother and child (development-centered care). Materials and method: A prospective cohort study was conducted in various hospitals on the West Bank in Palestine during 2008-2011. The universe was made up of an estimated average of 2,500 childbirths per year in each hospital. All of the subjects in the sample population of n = 252 babies had a gestational age of less than 37 GWs, and had weighed less than 2,500 grams at birth. For health reasons, they were hospitalized in neonatal care units. Results: The results obtained showed that in Palestine, young women tend to breastfeed their babies and have skin-to-skin contact with them more often than older mothers. Once the new mothers were informed of the advantages of these practices, they showed greater interest in learning how to care for their babies in the neonatal care units. Conclusions: Breastfeeding premature babies as well as having skin-to-skin contact with them was made possible by informing and teaching new mothers about the advantages of this type of infant care. This research has had widespread impact and has been very well received by the female population in the country. This is the first study of its kind to be carried out in Palestine.

Introduction: The energy needs of preterm infants are high and more so when the body weight is lower; for this reason, and to safeguard the infant’s future development, it is important to ensure an optimal caloric intake is obtained. Aim: To analyse leading research papers related to nutrition in the preterm newborn and its effects on growth and development. Method: Systematic review of relevant studies, based on the application of a search strategy, from March to September 2014. The literature search was conducted using document analysis and information synthesis to classify and compile the information extracted, followed by a comparative evaluation. The validity of the articles obtained was corroborated by the weight of findings obtained, by the citations received by the articles and by their applicability to our healthcare environment. Results: The search process produced 61 studies that met the selection criteria. The research question addressed has been widely examined and many studies have reported findings related to the nutrition of preterm infants. The direct relationship between nutritional intake and the growth rate of preterm infants is well documented. Conclusions: Proper nutrition in the preterm infant has positive effects on its growth and neurodevelopment. It has been reported that a greater intake of proteins and lipids favours the growth of preterm infants, but not weight gain. Studies have demonstrated the beneficial effect of breast milk on the brain, the retina and the blood vessels; however, there is a negative correlation between adiposity and brain volume. © 2015, Grupo Aula Medica S.A.

Recent studies show an alarming increase in levels of overweight and obesity among children and adolescents. The main objectives of this research were the following: (i) to carry out an anthropometric evaluation of the nutritional status and body composition of school children in the city and province of Granada; (ii) to compare the nutritional status of this population sample with national and international reference standards. The results obtained in this study showed that the general prevalence of overweight in both sexes was 22.03% and that 9.12% of the children were obese. Statistically significant differences were found between the variable, weight for age and sex (p < 0.05) and the variable, height for age and sex (p < 0.05). Regarding the body mass index, no statistically significant differences were found for the variable, sex (p = 0.182). This contrasted with the variable, age, which did show statistically significant differences (p < 0.05). As a conclusion, the results of our study highlighted the fact that these anthropometric values were much higher than national and international reference standards.
