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…
Online Vs In-person Education: Evaluating the Potential Influence of Teaching Modality on Dry Eye Symptoms and Risk Factors During the COVID-19 Pande…
2021
OBJECTIVES: To assess the potential effects of switching to online lecture format on dry eye symptoms and dry eye disease (DED) risk factors. METHODS: An anonymous cross-sectional online survey was conducted in 812 university students (mean age, 21.5±4.0 years). Participants were classified according to the number of hours the participants took online lectures into online students or in-person students. Respondents completed a total of three DED questionnaires (Ocular Surface Disease Index [OSDI]; 5-item Dry Eye Questionnaire; 8-item Contact Lens Dry Eye Questionnaire) and were surveyed on dry eye risk factors contemplated by the Tear Film and Ocular Surface Society Dry Eye Workshop II in a…
Temporal trends and determinants of peripartum hysterectomy in Lombardy, Northern Italy, 1996-2010.
2013
Purpose: To analyze the temporal trends of peripartum hysterectomy (PH) in the period 1996-2010 in Lombardy, Italy. Methods: Using data from the Regional Database, PH ratios/1,000 deliveries were calculated from 1996 to 2010, in strata of age and mode of delivery among women resident in Lombardy, Italy. PH cases were identified searching the database for the ICD-9 and ICD-10 codes for subtotal and total hysterectomy. PH ratios/1,000 deliveries in strata of age, mode of delivery and calendar year were computed. Poisson's regression analysis was used to test trend over time. Results: A total of 905 PH and 1,289,163 deliveries were recorded between 1996 and 2010. The overall PH ratio was 0.70/…
Identifying women with gestational diabetes based on maternal characteristics: an analysis of four Norwegian prospective studies
2021
Abstract Background There is still no worldwide agreement on the best diagnostic thresholds to define gestational diabetes (GDM) or the optimal approach for identifying women with GDM. Should all pregnant women perform an oral glucose tolerance test (OGTT) or can easily available maternal characteristics, such as age, BMI and ethnicity, indicate which women to test? The aim of this study was to assess the prevalence of GDM by three diagnostic criteria and the predictive accuracy of commonly used risk factors. Methods We merged data from four Norwegian cohorts (2002–2013), encompassing 2981 women with complete results from a universally offered OGTT. Prevalences were estimated based on the f…
Achievement of treatment targets predicts progression of vascular complications in type 1 diabetes.
2021
Abstract Background and aim To study the association between achievement of guideline-defined treatment targets on HbA1c, low-density lipoproteins (LDL-C), and blood pressure with the progression of diabetic complications in patients with type 1 diabetes (T1D). Methods The study included 355 patients at baseline and 114 patients with follow-up data after 3–5 years. Outcome variables were the progression of diabetic kidney disease, retinopathy, or cardiovascular disease (CVD). We used logistic regression and other machine learning algorithms (MLA) to model the association of achievement of treatment targets and probability of progression of complications. Results Achievement of the target bl…
Prenatal Exposure to Polybrominated Flame Retardants and Fetal Growth in the INMA Cohort (Spain)
2015
Our aim was to investigate the relation between PBDEs and fetal growth or newborn anthropometry in a Spanish cohort (2003-2008). PBDE congeners (BDE-47, -99, -153, -154, and -209) were determined in serum of 670 mothers at gestational week 12 and in 534 umbilical cord samples. Abdominal circumference (AC), estimated fetal weight (EFW), femur length (FL), and biparietal diameter (BPD) during gestation were measured by ultrasounds. At birth, weight (BW), head circumference (HC), and length (BL) were also measured. We assessed growth in the intervals between 12-20 and 20-34 weeks of gestation and size at birth by standard deviation (SD)-scores adjusted for constitutional characteristics. We co…
Oral Health Knowledge and Related Factors among Pregnant Women Attending to a Primary Care Center in Spain
2019
Our aim was to assess the knowledge of pregnant women in terms of oral health and prevention, correlating it with socio-sanitary and educational factors, as well as self-care and oral health state referred. A total of 139 women from a Health Department in Comunidad Valenciana (Valencia, Spain) participated in the study. They underwent an auto-administered survey which included socio-economic and educational factors, self-care in terms of oral hygiene, referred oral health state, and general knowledge on prevention and oral health. Chi-squared test (&chi
Interpersonal Violence and Women's Psychological Well-Being
2011
The health impact of violence against women by perpetrators other than intimate partners has received little attention. This study aims to analyze the effect of different forms of interpersonal violence on women's health.Adult women (10,815) randomly sampled from primary healthcare services around Spain were included. Women were grouped as follows: (1) no history of violence, (2) history of intimate partner violence only (IPV), (3) history of non-IPV only, and (4) history of both IPV and non-IPV. Lifetime prevalence of violence by IPV, non-IPV, and both was calculated. Adjusted multivariable regression analysis was performed to assess the effects of the different forms of violence on women'…
Prevalence of Parental Alcohol Problems among a General Population Sample of 28,047 Norwegian Adults: Evidence for a Socioeconomic Gradient
2021
The aim of the study presented here was to estimate the prevalence of parental alcohol problems during childhood in a general population of Norwegian adults, and to investigate associations between parental alcohol problems during childhood and lower socioeconomic status in adulthood. This cross-sectional study recruited 28,047 adults (≥18 years) to an online health survey (Norwegian Counties Public Health Surveys). We evaluated demographic and socioeconomic measures and responses to a shortened version of the Children of Alcoholics Screening Test (CAST-6) scale to assess whether respondents perceived parental alcohol consumption during childhood as problematic. Respondents reported parenta…
Neuromuscular performance and body mass as indices of bone loading in premenopausal and postmenopausal women.
2009
The strong association between body mass and skeletal robusticity has been attributed to increasing skeletal loading with increasing mass. However, it is unclear whether body mass is merely a coarse substitute for bone loading rather than a true independent predictor of bone strength. As indices of neuromuscular performance, impulse and peak power were determined from vertical ground reaction force during a maximal counter movement jump test in 221 premenopausal and 82 postmenopausal women. Bone compressive (BSI(d) g(2)/cm(4)) and bending (SSImax(mid) mm(3)) strength indices were measured with peripheral quantitative computed tomography (pQCT) at the distal ((d)) and midshaft ((mid)) sites …
