Physical activity and breast cancer risk by pathological subtype
2017
Abstract Objective To examine the influence of physical activity on breast cancer risk and evaluate whether adherence to international recommendations is associated with a decreased risk. Methods This is a multicenter matched case-control study where 698 pairs completed a physical activity questionnaire. Recreational physical activity during the last year was quantified in metabolic equivalent hours per week (MET-h/week) and categorized in activities of moderate (3.0–5.9 MET) and vigorous (>6 MET) intensity. The adherence to World Cancer Research Fund and the American Institute for Cancer Research recommendation was also assessed. The association with breast cancer risk, overall and by path…
Are under- and overweight female elite athletes thin and fat? A controlled study.
2012
Purpose: The study�s purpose was to relate body mass index (BMI) to body fat percentage as measured by dual-energy x-ray absorptiometry in female elite athletes from different sports and nonathletic controls and to investigate what characterizes the athletes with unhealthy low and high body fat values. Methods: This study was conducted in three phases: 1) screening with a detailed questionnaire, 2) body composition measurement (dual-energy x-ray absorptiometry), and 3) clinical interview. All female elite athletes representing national teams at the junior or senior level age 13�39 yr (n = 938) and an age group�matched randomly selected population-based control group (n = 900) were invited t…
Mean maternal second-trimester hemoglobin concentration and outcome of pregnancy: a population-based study.
2008
Both anemia and the lack of physiological maternal plasma volume expansion during the second trimester are associated with higher maternal morbidity and poor fetal outcome. Mean hemoglobin levels between the 14th and 30th gestational weeks were calculated in 4985 consecutive pregnant women and were correlated with outcome data of pregnancy. It was found that 9.4% of participants (n = 3959) had normal pregnancy outcome. Mean maternal hemoglobin levels were significantly lower in women with a normal pregnancy (11.96 ± 0.94 g/dL) compared with women who had adverse outcome events (preeclampsia, n = 423, 12.5 ± 1.0 g/dL, P < .0001; early birth, n = 464, 12.2 ± 1.01 g/dL, P < .0001; low b…
Hormonal and psychological factors linked to the increased thermic effect of food in malnourished fasting anorexia nervosa
2007
In patients with anorexia nervosa (AN), weight gain is lower than that expected from the energy content of the meals. Thus we investigated the thermic effect of food (TEF) in relation to subjective feelings and plasma hormone levels in a group of AN patients.TEF, feelings (14 items), and plasma release of beta-endorphin, ACTH, cortisol, dopamine, and catecholamines were evaluated in 15 AN patients (body mass index, 13.6 +/- 1.2 kg.m(-2)) and in 15 healthy women after three gastric loads (0, 300, 700 kcal) infused by a nasogastric tube in a blind design.In AN, the blind loads induced an energy-dependent increase in TEF (P0.001), which was higher than that observed in healthy women (P0.001). …
Maternal and Neonatal Characteristics for Late Foetal Death in Latvia between 2001 and 2014: Population-Based Study
2018
Introduction. Stillbirth is one of the most common adverse pregnancy outcomes worldwide. Late foetal death (LFD) rates are mostly used for international comparisons because of the large variations in stillbirth rates between countries. Objective. To examine trends in LFD (including antepartum and intrapartum) by multiple births, birth weight, and maternal age in two time periods. Methods. A retrospective cohort study was used to analyse data from the Medical Birth Register (2001–2014), divided into 2 periods of 7 years each. In total, data on 1,340 singletons were analysed. This study calculated LFD rates and rate ratios (RR). Results. The overall LFD rate showed a slight statistically sign…
Assessment of ten trace elements in umbilical cord blood and maternal blood: association with birth weight
2015
Background Trace elements are an essential nutritional component for humans and inadequate tissue-concentrations may have a significant effect on fetal size. Objective To measure ten trace elements in blood samples from mothers and their newborns, and assess their association with anthropometric characteristics at birth. The effects of other factors on fetal growth, such as biologic characteristics of the infant and mother, were analysed. Methods A cross-sectional study was conducted in the Hospital general, University of Valencia, Spain. Healthy pregnant women, and their full-term infants were selected (n = 54 paired samples). Infants were grouped according to birth weight: small for gesta…
Metabolomic profiling in blood from umbilical cords of low birth weight newborns
2012
AbstractBackgroundLow birth weight has been linked to an increased risk to develop obesity, type 2 diabetes, and hypertension in adult life, although the mechanisms underlying the association are not well understood. The objective was to determine whether the metabolomic profile of plasma from umbilical cord differs between low and normal birth weight newborns.MethodsFifty healthy pregnant women and their infants were selected. The eligibility criteria were being born at term and having a normal pregnancy. Pairs were grouped according to their birth weight: low birth weight (LBW, birth weight < 10thpercentile, n = 20) and control (control, birth weight between the 75th-90thpercentiles, n…
Effects of hypocaloric very-low-carbohydrate diet vs. Mediterranean diet on endothelial function in obese women
2009
Obesity is a cardiovascular risk factor associated with endothelial dysfunction, but the effect of different weight loss strategies on endothelial function is not known. The effect of diet on endothelial function in two hypocaloric diets, a very-low-carbohydrate diet (A) and a Mediterranean diet (M), was measured by brachial artery flow-mediated dilation (FMD). Design Using a longitudinal, randomized, open study design, subjects were engaged in a 2-month weight loss diet. FMD, inflammatory cytokines [interleukin-6 (IL-6) and tumour necrosis factor-alpha] and a marker of oxidative stress [8-iso-prostaglandin F2alpha (8-iso-PGF2alpha)] were measured in subjects on three occasions: before init…
Human breast areolae as scent organs: morphological data and possible involvement in maternal-neonatal coadaptation.
2006
In humans, areolar skin glands (AG) enlarge during pregnancy and lactation. Their role in mother-infant interactions may pertain to protective, mechanical, and communicative functions. It was questioned here whether more profuse AG could be related to more optimal adaptation to breastfeeding. A morphological study of the areolae was undertaken between birth and day 3 to assess the number, secretory status, and spatial distribution of AG. These data were related to infants' weight variation, mothers' perception of their infant's behavior at breast, and time between delivery and onset of lactation. AG were seen in virtually all women but with great interindividual variations; their areolar di…
Health literacy and its relation to continuing with breastfeeding at six months post-partum in a sample of Spanish women
2021
Aim To explore the relation between health literacy (HL) and continuing breastfeeding (BF) at 6 months post-partum. Design Observational, longitudinal and prospective study between December 2018–May 2019. The STROBE checklist was used. Methods 114 mother/baby pairings from a Spanish Hospital were included. Mothers’ health literacy was studied with the Newest Vital Sign and Short Assessment of Health Literacy for Spanish Adults 50 (SAHLSA-50). Before hospital discharge, BF efficiency was studied using the LATCH BF score and BF continuity was followed for 6 months. Survival analysis and Cox regression were done. Results Health literacy levels and BF effectiveness were adequate before hospital…
