AbstractObjectiveTo examine overall micronutrient intake periconceptionally and throughout pregnancy in a population-based cohort of Australian women.DesignIn a prospective cohort study, micronutrient dosages were extracted from self-reported maternal supplement use, recorded pre-conception, and for each trimester of pregnancy. A food frequency scale (DQESv2) captured usual maternal diet for gestational weeks 14–26. The influence of sociodemographic and lifestyle factors associated with supplement use was examined using logistic regression, and changes in micronutrient intakes prior to and throughout pregnancy were assessed using repeated-measures ANOVA analyses.SettingMetropolitan hospital sites in Melbourne, Australia.SubjectsWomen with a viable singleton pregnancy were recruited at less than 19 weeks’ gestation (n2146).ResultsCompared with non-users, women using supplements during pregnancy were more likely to have planned their pregnancy, be >25 years old, primiparous, Caucasian, non-smokers, have a tertiary education and be consuming a folate-rich diet. Intakes of folate, Fe and Zn were significantly lower in the periconceptional period, compared with other periods (P<0·001). Intakes below Recommended Daily Intake levels were common both periconceptionally and throughout pregnancy, with 19–46 % of women not meeting the Recommended Daily Intake for folate, 68–82 % for Fe and 17–36 % for Zn. Conversely, 15–19 % of women consumed beyond the recommended Upper Limit for folate and 11–24 % for Fe.ConclusionsThe study highlights the need for improved public health education on nutritional needs during pregnancy, especially among women with lower educational achievements and income.

Risk Of Death

Abstract Background Falls in later life that require admission to hospital have well-established consequences for future disability and health. The likelihood and severity of a fall will result from the presence of one or more risk factors. The aim of this study is to examine risk factors identified for their ability to prevent falls and to assess whether they are associated with hospital admission after a fall. Methods Analyses of data from the English Longitudinal Study of Aging (ELSA), a prospective cohort study. In a sample of 3783 men and women older than 60 years old, a range of potential risk factors measured at Wave 4 (demographic, social environment, physical, and mental functioning) were examined as predictors of fall-related hospitalizations, identified using International Classification of Diseases, 10th Revision (ICD-10) code from linked hospital records in the United Kingdom. Subdistribution hazard models were used to account for competing risk of death. Results Several risk factors identified by previous work were confirmed. Suffering from urinary incontinence (subdistribution hazard ratio = 1.49; 95% CI: 1.14, 1.95) and osteoporosis (subdistribution hazard ratio = 1.48; 95% CI: 1.05, 2.07), which are not commonly considered at an early stage of screening, were found to be associated with hospital admission after a fall. Both low and moderate levels of physical activity were also found to somewhat increase the risk of hospital admission after a fall. Conclusions Several predictors of having a fall, severe enough to require hospital admission, have been confirmed. In particular, urinary incontinence should be considered at an earlier point in the assessment of risk.

Aim. To study the risk of cardiovascular and all-cause mortality in patients with metabolic syndrome (MS) according to a 14-year prospective cohort study in Siberia.Material and methods. Based on the data from the Russian arm of the HAPIEE project, we assessed all-cause deaths occurred by 2017 in the population cohort examined at baseline in 2003-2005 (n=9273). The baseline examination included the assessment of blood pressure (BP), anthropometry, levels of fasting triglycerides, high density lipoprotein cholesterol (HDL-C), and blood glucose. The fatal cases in the studied cohort were identified from “Medical death certificates” for the period from February 1, 2003 to December 31, 2017, based on data from the Department of Civil Registration of Death Acts. Cardiovascular death was established using the International Classification of Diseases, the 10th revision (ICD-10): I (0-99).Results. The mortality rate in subjects with MS was 16,6% — 751 deaths (25,1% in men and 11,5% in women), and it was 20-30% higher than in those without MS. Cardiovascular mortality in subjects with MS was 12,6% — 572 deaths (20,5% in men and 8,9% in women), and it was nearly 30% higher than in those without MS. Multivariable Cox regression revealed that among the components of MS, the elevated BP level even with BP ≥135/80 mm Hg had the major impact on increasing the risk of all-cause mortality (HR=1,7 (1,4; 2,1) in men; HR=2,2 (1,7; 2,8) in women) and increasing the risk of cardiovascular mortality (HR=2,2 (1,5; 3,0) in men and HR=2,8 (1,8; 4.3) in women). Among men, already 1 component of MS increased the risk of cardiovascular and all-cause mortality by 2,0 or more times; among women, 2-4 components of MS increased the risk of death by 3 times, and 5 components — by 4.Conclusion. In the studied population sample, cardiovascular and all-cause mortality during the 14-year follow-up in individuals with MS was about 25-30% higher compared to those without MS. The risk of cardiovascular and all-cause deaths in subjects with MS is comparable to the risk in case of blood pressure ≥135/80 mm Hg. With an increase in the number of MS components from 1 to 5, the risk of all-cause and cardiovascular death increases.

Anthropometric assessment during pregnancy is a widely used, low-technology procedure that has not been rigorously evaluated. Our objective is to investigate fat mass distribution during pregnancy by examining changes in anthropometrics measures, in order to evaluate the reliability of these measures. An observational, longitudinal, prospective cohort study was performed in 208 pregnant women. Anthropometric measurements were taken following the ISAK protocol during the three trimesters and a generalized linear model for repeated measures was used to evaluate differences. Variability was assessed using the coefficient of variation, and Propagated Error (PE) was used to sum of skinfold thicknesses (SFT). SFT showed a general increase in fat mass during the three trimesters of pregnancy (∑SFT7 p = 0.003), and was observed in specific anatomical locations as well: arms (∑Arm SFT, p = 0.046), trunk (∑Trunk SFT, p = 0.019), legs (∑Leg SFT, p = 0.001) and appendicular (∑Appendicular SFT, p = 0.001). Anthropometric measures for skinfold thickness were taken individually during pregnancy and were reliable and reproducible during the three trimesters, which could help to prevent adverse pregnancy outcomes.
