Midwives' Belief in Normal Birth: The Canadian Survey of Maternity Care Providers’ Attitudes Toward Labour and Birth

Background: Midwifery has been integrated into the health care systems of over half of Canadian provinces and territories. While there are differences in legislation and payment mechanisms, the model of midwifery is fairly similar across the country. This study examined the similarities and differences among midwives' attitudestowardlabourandbirth. Inaddition,wecompareditemswhichrelatedtobeliefsaboutnormal birth between midwives and other care providers.Methods: A national cross-sectional survey was conducted comparing maternity care providers’ beliefs aboutchildbirthandintra-professionalvariationsinmidwives'attitudestowardsbirth. Therewere400 (54%) midwife respondents: 218 from Ontario, 75 from B.C, 53 from Quebec, 48 from the remaining regulated or pre-regulated provinces (six missed information for this field).Results: All midwives were critical of the routine use of interventions such as episiotomy, epidural analgesia andelectronicfetalmonitoring(EFM). Therewasstrongagreementaboutthesafetyofhomebirth,outof hospital birth centres and the importance of women's autonomy and decision-making in pregnancy and birth. However, some regional variations were identified. Quebec midwives were more opposed to epidural analgesia than BC and Ontario (p<.001), and were more likely to believe that cesarean birth is more costly than vaginal birth (p=.005). Ontario midwives were most likely to believe that cesarean birth protects against urinary incontinence (p=.001), and sexual dysfunction (p=.002). Qualitative comments of midwives indicated a strong desire to reduce unnecessary medical intervention and to lower cesarean section rates.Conclusion: Canadian midwives share similar beliefs regarding place of birth, the routine use of episiotomy, EFM, and epidurals, but reported significant attitudinal differences for other issues. Regional differences may be related to midwives' primary practice settings, the historical development of midwifery in their region and the number of new midwives with less than 5 years of clinical experience. A set of core midwifery values was identified that demonstrate a strong belief in normal birth.

Examining determinants of stunting in Urban and Rural Indonesian: a multilevel analysis using the population-based Indonesian family life survey (IFLS).

In Indonesia, chronic malnutrition leading to stunted growth in children represents a significant issue within the public health domain. The prevalence of stunting varies between urban and rural areas, reflecting disparities in access to nutrition, healthcare, and other socioeconomic factors. Understanding these disparities is crucial for developing targeted interventions to address the issue. The study used data from the fifth wave of the Indonesian Family Life Survey (IFLS), which is a national cross-sectional population-based survey conducted across approximately 13 provinces in Indonesia in 2014-2015. Multivariate and Multilevel logistic regression models were utilized in the analysis to determine the factors associated with the prevalence of stunting in Indonesian children. The multivariate logistic regression analysis indicated that among children aged 24-59 months in Indonesia, stunting was associated with the age of the child, birth weight, maternal nutritional status, and residence. Subsequently, the multilevel logistic regression analysis revealed that in rural areas, the age of the child and birth weight exhibited significant associations with stunting. Conversely, in urban areas, stunted children were influenced by 7 factors, including the child's age (months), age of weaning, birth weight (kg), mother and father's age, place of birth, and maternal nutritional status. Variations in childhood stunting between urban and rural regions in Indonesia were observed, indicating a differential prevalence. The study's findings suggests the importance of age-appropriate nutritional support, healthcare interventions, and growth monitoring. Focused interventions are vital, potentially encompassing initiatives such as improving access to maternal and child healthcare services, promoting adequate nutrition during pregnancy and infancy, and facilitate greater parental engagement in childcare responsibilities.

Effects of Racist Microaggressions and Sexual and Gender Minority Stress on Mental Health Among Latinx Lesbian, Gay, Bisexual, Transgender, and Queer or Questioning + Young Adults.

This study examines the effects of racist microaggressions and lesbian, gay, bisexual, transgender, and queer/questioning (LGBTQ)-related minority stressors (i.e., identity concealment, family rejection, internalized LGBTQ-phobia, victimization, and racialized heterosexism/cisgenderism) on psychological distress among Latinx LGBTQ+ young people, specifically college students. Participants are a Latinx subset (n = 80) from a national online nonprobability cross-sectional survey of LGBTQ+ college students. The study aim was examined using linear/logistic regression. Findings indicated that racist microaggressions and family rejection were associated with psychological distress. In addition, racist microaggressions were the only stressor associated with clinically significant psychological distress that may warrant psychiatric/psychological treatment. Therefore, racist microaggressions and family rejection are unique stressors that may saliently affect mental health among Latinx LGBTQ+ students. There is a great need to integrate minority stress theory with other critically-oriented theories, such as intersectionality, in research and intervention to eliminate mental health inequities faced by Latinx LGBTQ+ young people.

Is food and drink advertising across various settings associated with dietary behaviours and intake among Australian adolescents? Findings from a national cross-sectional survey.

The pervasive promotion of energy-dense, nutrient-poor food and drinks undermines efforts by adolescents and their parent/carers to maintain a nutritious diet during a crucial developmental period. This study examined the association between awareness of food and drink advertisements and adolescents' dietary behaviours and intake. A sample of Australian secondary students aged 12-17 years (N = 8763) self-reported their awareness of food and drink advertisements across seven settings, whether they had tried a new product or asked a parent/carer to purchase a product they had seen advertised, and their consumption of various unhealthy food and drink types. Analyses used multilevel mixed-effects generalised linear models adjusted for school-level clustering, socio-demographic factors and television viewing. Students with higher advertising awareness were more likely to have tried a new product they had seen advertised (adjusted prevalence ratio [APR] = 1.62, 95% CI = 1.51-1.73, p < .001) and asked their parent/carer to buy an advertised product (APR = 1.62, 95% CI = 1.51-1.73, p < .001) at least once in the past month. As advertising awareness increased, so too did students' likelihood of reporting these dietary behaviours. A high unhealthy food intake was more commonly reported among students with higher advertising awareness (APR = 1.45, 95% CI = 1.32-1.58, p < .001), as was a high unhealthy drink intake (APR = 1.29, 95% CI = 1.18-1.42, p < .001). Australian adolescents are vulnerable to the persuasive effects of food and drink marketing. SO WHAT?: Greater restrictions on the way the food and drink industry can market their products to adolescents are needed to better support them in developing and maintaining positive dietary behaviours.

Prevalence of different variations of non-consented care during the childbirth process in Mexico by geographical regions: comparing ENDIREH survey data from 2016 to 2021

IntroductionNon-consented care, a form of obstetric violence involving the lack of informed consent for procedures, is a common but little-understood phenomenon in the global public health arena. The aim of this secondary analysis was to measure the prevalence and assess change over time of non-consented care during childbirth in Mexico in 2016 and 2021, as well as to examine the association of sociodemographic, pregnancy-, and childbirth-factors with this type of violence.MethodsWe measured the prevalence of non-consented care and three of its variations, forced sterilization or contraception, forced cesarean section, and forced consent on paperwork, during childbirth in Mexico for 2016 (N = 24,036) and 2021 (N = 19,322) using data from Mexico’s cross-sectional National Survey on the Dynamics of Household Relationships (ENDIREH). Weighted data were stratified by geographical regions. We performed adjusted logistic regression analyses to explore associations.ResultsThe national prevalence of non-consented care and one of its variations, pressure to get a contraceptive method, increased from 2016 to 2021. A decrease in the prevalence was observed for forced contraception or sterilization without knowledge, forcing women to sign paperwork, and non-consented cesarean sections nationally and in most regions. Women between the ages of 26 and 35 years, married, cohabiting with partner, living in urban settings, who do not identify as Indigenous, and who received prenatal services or gave birth at the Mexican Institute of Social Security (IMSS) facilities experienced a higher prevalence of non-consented care. Being 26 years of age and older, living in a rural setting, experiencing stillbirths in the last five years, having a vaginal delivery, receiving prenatal services at IMSS, or delivering at a private facility were significantly associated with higher odds of reporting non-consented care.ConclusionWhile a decrease in most of the variations of non-consented care was found, the overall prevalence of non-consented care and, in one of its variations, pressure to get contraceptives, increased at a national and regional level. Our findings suggest the need to enforce current laws and strengthen health systems, paying special attention to the geographical regions and populations that have experienced higher reported cases of this structural problem.

Trends of physical activity and recreational screen time among Chinese children and adolescents: a national study from 2017 to 2019

BackgroundThe prevalence of physical inactivity and sedentary behavior among children and adolescents is a growing public health concern. This study aims to examine the trends in Physical Activity (PA) and Recreational Screen Time (RST) amongst children and adolescents in China, considering variations in genders, school levels, areas (urban versus rural), and regions (north versus south). The findings provide a foundation to guide policy and strategy making for future health promotion and development.MethodsAn annual national cross-sectional survey was conducted in China from 2017 to 2019 cumulatively involving 52,503 (48% female) children and adolescents from grades 4 to 12 (aged 12.72 ± 2.12). Data on PA and RST were collected through self-administered questionnaires. Weighted least squares regression was used to analyze the trends and differences in PA and RST among the participants’ profiles.ResultsThere was an annual decreased in PA compliance rate of approximately 3.43% (95% CI: 0.79-6.08%) for primary school students, primarily among males residing in rural areas, and in northern regions. Middle school students experienced a yearly decrease of about 5.23% (95% CI: 2.55-7.92%) in PA compliance across all genders, regions, and urban areas. Similarly, the RST compliance rates for primary school students declined by approximately 3.18% (95% CI: 1.57-4.78%) annually for all genders and areas, but only in the northern regions.ConclusionsThis research highlights a downward trend in PA and RST compliance amongst Chinese children and adolescents, with variations based on school level, gender, area, and region. Urgent policies and interventions are imperative to promote PA while mitigating excessive RST within these populations.

Trends in research grant applications and outcomes among medical students in the United Kingdom: a national self-reported cross-sectional survey.

Background: Research funding disparities contribute to clinical-academic workforce inequalities1-3. Hence, our study explores the association between student demographics and research grant application rates and outcomes among UK medical students. Methods: This is a national multicentre cross-sectional survey of UK medical students in the 2020-21 academic year. Multiple zero-inflated negative binomial regression and generalized linear model (binomial distribution; logit link) were utilized to investigate the association between student demographics, number of grant applications submitted, and successful grant applications (yes or no). P-values less than a Bonferroni-corrected significance level of 0.05/36 = 0.0014 were statistically significant. Results: 1528 students participated from 36 medical schools. 151 respondents (9.9%) had applied for research grants. Black students submitted applications 2.90 times more often than white students [Incident rate ratio (IRR): 2.90, 95% confidence interval (CI): 1.37-6.16], with no ethnic disparity in the odds of successful applications. Gender did not influence application rates significantly (P = .248), but women were 4.61 times more likely to secure a grant than men [odds ratio: 4.61, 95% CI: 2.04-10.4]. Being a PubMed-indexed author was associated with increased grant application submission rates [IRR: 3.61, 95% CI: 2.20- 5.92] while conducting more research was associated with greater odds of securing a grant [odds ratio: 1.42, 95% CI: 1.17- 1.73]. Conclusion: Although black students submitted more applications, ethnicity did not influence success rates. Gender did not influence application rates, but women were more successful. These findings underscore the need for strategies supporting women and underrepresented students for continued academic achievement after graduation. This abstract has been published as a paper4

Prevalence and Disparities in Telehealth Use Among US Adults Following the COVID-19 Pandemic: National Cross-Sectional Survey.

Telemedicine expanded during the COVID-19 pandemic, though use differed by age, sex, race or ethnicity, educational attainment, income, and location. It is unclear if high telehealth use or inequities persisted late into the pandemic. This study aims to evaluate the prevalence of, inequities in, and primary reasons for telehealth visits a year after telemedicine expansion. We used cross-sectional data from the 2022 Health Information National Trends Survey (HINTS 6), the first cycle with data on telemedicine. In total, 4830 English- and Spanish-speaking US adults (aged ≥18 years) were included in this study. The primary outcomes were telehealth visit attendance in the 12 months before March 7, 2022, to November 8, 2022, and the primary reason for the most recent telehealth visit. We evaluated sociodemographic and clinical predictors of telehealth visit attendance and the primary reason for the most recent telehealth visit through Poisson regression. Analyses were weighted according to HINTS 6 standards. We included 4830 participants (mean age 48.3, SD 17.5 years; 50.28% women; 65.21% White). Among US adults, 38.78% reported having a telehealth visit in the previous year. Telehealth visit attendance rates were similar across age, race or ethnicity, income, and urban versus rural location. However, individuals with a telehealth visit were less likely to live in the Midwest (adjusted prevalence ratio [aPR] 0.65, 95% CI 0.54-0.77), and more likely to be women (aPR 1.21, 95% CI 1.06-1.38), college graduates or postgraduates (aPR 1.24, 95% CI 1.05-1.46), covered by health insurance (aPR 1.56, 95% CI 1.08-2.26), and married or cohabitating (aPR 1.17, 95% CI 1.03-1.32), adjusting for sociodemographic characteristics, frequency of health care visits, and comorbidities. Among participants with a telehealth visit in the past year, the primary reasons for their most recent visit were minor or acute illness (32.15%), chronic disease management (21%), mental health or substance abuse (16.94%), and an annual exam (16.22%). Older adults were more likely to report that the primary reason for their most recent telehealth visit was for chronic disease management (aPR 2.08, 95% CI 1.33-3.23), but less likely to report that it was for a mental health or substance abuse issue (aPR 0.19, 95% CI 0.10-0.35), adjusting for sociodemographic characteristics and frequency of health care visits. Among US adults, telehealth visit attendance was high more than a year after telemedicine expansion and did not differ by age, race or ethnicity, income, or urban versus rural location. Telehealth could continue to be leveraged following COVID-19 to improve access to care and health equity.

Tending to the machine: The impact of intrapartum fetal surveillance on women in Australia

Qualitative research about women and birthing people’s experiences of fetal monitoring during labour and birth is scant. Labour and birth is often impacted by wearable or invasive monitoring devices, however, most published research about fetal monitoring is focused on the wellbeing of the fetus. This manuscript is derived from a larger mixed methods study, ‘WOmen’s Experiences of Monitoring Baby (The WOMB Study)’, aiming to increase understanding of the experiences of women and birthing people in Australia, of being monitored; and about the information they received about fetal monitoring devices during pregnancy. We constructed a national cross-sectional survey that was distributed via social media in May and June, 2022. Responses were received from 861 participants. As far as we are aware, this is the first survey of the experiences of women and birthing people of intrapartum fetal monitoring conducted in Australia. This paper comprises the analysis of the free text survey responses, using qualitative and inductive content analysis. Two categories were constructed, Tending to the machine, which explores participants’ perceptions of the way in which clinicians interacted with fetal monitoring technologies; and Impressions of the machine, which explores the direct impact of fetal monitoring devices upon the labour and birth experience of women and birthing people. The findings suggest that some clinicians need to reflect upon the information they provide to women and birthing people about monitoring. For example, freedom of movement is an important aspect of supporting the physiology of labour and managing pain. If freedom of movement is important, the physical restriction created by a wired cardiotocograph is inappropriate. Many participants noticed that clinicians focused their attention primarily on the technology. Prioritising the individual needs of the woman or birthing person is key to providing high quality woman-centred intrapartum care. Women should be provided with adequate information regarding the risks and benefits of different forms of fetal monitoring including how the form of monitoring might impact her labour experience.

Comparing preferences to evaluations of barrier self-efficacy for two strength training programs in US older adults.

Engagement in regular physical activity is one of the best strategies for older adults to remain healthy. Unfortunately, only 35% of older adults meet guidelines for muscle strengthening activities. Eliciting participant preferences is one possible way to improve physical activity engagement. However, other sources of participant input to improve uptake and maintenance remain uninvestigated. This study compared preferences to self-efficacy ratings for two strength training programs. We conducted a national cross-sectional survey of 611 US adults over age 65. We compared two participant evaluations (the preferred program and the program for which they had higher barrier self-efficacy) of two hypothetical strength training programs (45 minutes performed three times per week (traditional) and 5 minutes performed daily (brief)). Most participants (68%) preferred the brief strength training program. The difference in self-efficacy ratings was an average of 1.2 (SD = 0.92). One in five participants preferred a strength training program for which they had less self-efficacy; nearly all of these participants (92%) preferred the traditional strength training program but had more self-efficacy for the brief strength training program. Older adults reported preferring and having more self-efficacy for a brief compared to a traditional strength training program. Differences in self-efficacy ratings between the two strength training programs were large. Preferences were often not congruent with ratings of self-efficacy. Preferences for strength training programming may not always reflect the program most likely to be maintained. Future investigations should evaluate differences in behavioral uptake, maintenance, and outcomes from two comparative strength training interventions using preferences and self-efficacy.

Burden of Mental Disorders and Suicide Attributable to Childhood Maltreatment

The proportion of mental disorders and burden causally attributable to childhood maltreatment is unknown. To determine the contribution of child maltreatment to mental health conditions in Australia, accounting for genetic and environmental confounding. This meta-analysis involved an epidemiological assessment accounting for genetic and environmental confounding between maltreatment and mental health and 3 cross-sectional national surveys: the Australian Child Maltreatment Study (ACMS) 2023, National Study of Mental Health and Well-being 2020-2022, and Australian Burden of Disease Study 2023. Causal estimates were derived on the association between childhood maltreatment and mental health conditions from a meta-analysis of quasi-experimental studies. This was combined with the prevalence of maltreatment from the ACMS to calculate the population attributable fraction (PAF). The PAF was applied to the number and burden of mental health conditions in Australia, sourced from 2 population-based, nationally representative surveys of Australians aged 16 to 85 years, to generate the number and associated burden of mental disorders attributable to child maltreatment. Physical abuse, sexual abuse, emotional abuse, or neglect prior to age 18 years. Proportion and number of cases, years of life lost, years lived with disability, and disability-adjusted life-years of mental health conditions (anxiety, depression, harmful alcohol and drug use, self-harm, and suicide attempt) attributable to childhood maltreatment. Meta-analytic estimates were generated from 34 studies and 54 646 participants and applied to prevalence estimates of childhood maltreatment generated from 8503 Australians. Childhood maltreatment accounted for a substantial proportion of mental health conditions, ranging from 21% (95% CI, 13%-28%) for depression to 41% (95% CI, 27%-54%) of suicide attempts. More than 1.8 million cases of depressive, anxiety, and substance use disorders could be prevented if childhood maltreatment was eradicated. Maltreatment accounted for 66 143 years of life lost (95% CI, 43 313-87 314), primarily through suicide, and 184 636 disability-adjusted life-years (95% CI, 109 321-252 887). This study provides the first estimates of the causal contribution of child maltreatment to mental health in Australia. Results highlight the urgency of preventing child maltreatment to reduce the population prevalence and burden of mental disorders.

Comparing harm reduction and overdose response services between community-based and public health department syringe service programmes using a national cross-sectional survey

Syringe services programmes (SSPs) are an evidence-based strategy to reduce infectious diseases and deliver overdose prevention interventions for people who use drugs. They face regulatory, administrative, and funding barriers that limit their implementation in the US, though the federal government recently began providing funding to support these efforts. In this study we aim to understand whether the organisational characteristics of SSPs are associated with the provision of syringe and other overdose response strategies. We examine four outcomes using the National Survey of Syringe Services Programs (NSSSP) (N=472): syringe distribution, naloxone distribution, fentanyl test strip (FTS) availability, and buprenorphine implementation. These outcomes are assessed across three organizational categories of SSPs-those operated by public health departments (DPH), community-based organizations (CBOs) with government funding, and CBOs without government funding-while adjusting for community-level confounders. The proportion of SSPs by organizational category was 36% DPH, 42% CBOs with government funding, and 22% CBOs without government funding. Adjusting for community-level differences, we found that CBO SSPs with government funding had significantly higher provision of all four syringe and overdose response services as compared to DPH SSPs and across three of the four services as compared to CBO SSPs without government funding. CBO SSPs without government funding still had significantly higher provision of three of the four services as compared to programmes maintained by the DPH. CBO SSPs have strong potential to expand overdose response services nationally, particularly if provided with sustained and adequate funding. Communities should aim to provide funding that does not hinder SSP innovation so they can remain flexible in responding to local needs. This study was supported by Arnold Ventures (20-05172).

Does socioeconomic disadvantage explain why immigrants in Sweden refrain from seeking the needed medical treatment?

Background: For the last 20 years, Sweden has changed from a homogeneous to multicultural society with about 20% of immigrants born in other countries. The existing Swedish studies have not shown coherent results on how access to health care services varies by ethnicity. The aim of this paper was to analyze the association between country of birth and refraining from seeking medical treatment and whether socioeconomic disadvantage modifies this association. Methods: Cross-sectional Swedish National Survey of Public Health 2004. A population-based sample comprising of 14,732 men (1,382 immigrants) and 17,115 women (1,717 immigrants) aged 21 to 84 years. Country of birth was categorised as being born in Sweden, other OECD countries or other countries (non- OECD). The main outcome was the self-reporting of refraining from seeking medical treatment during the past three months. Data was collected within a three-month period during the spring of 2004 and was based on a postal self-administered questionnaire linked to registry data from Statistics Sweden. The nonresponse rate was 37%. Main results: In spite of the fact that immigrants reported poorer health status, they were more likely to refrain from seeking medical treatment as compared to Swedish-born residents (odds for immigrants from other OECD countries were ORmen = 2.2, 95% CI 1.8-2.6 and ORwomen = 1.8, 95% CI 1.5-2.1 and for immigrants from other countries (ORmen = 3.1, 95% CI 2.4-3.4 and ORwomen = 2.3, 95% CI 1.8-2.9). Socioeconomic disadvantage (SDI) did not explain why immigrants fromother OECD countries had increased odds for refraining fromseekingmedical treatment. However SDI explained about 20%of the increased odds for refraining from seeking medical treatment among immigrants from other (non-OECD) countries. Conclusions: Socioeconomic disadvantage does not fully explain why immigrants refrain from seeking medical treatment. Public health strategies towards the goal “care on equal terms” cannot be achieved without addressing wider socioeconomic determinants including interactions between class and ethnicity.

Parental experience after diagnosis of a congenital upper limb difference: a national survey.

Congenital hand and upper limb differences may be detected during antenatal ultrasonography or visually at birth. We investigated the experience of parents when they first learned that their child had an upper limb difference. This national retrospective cross-sectional quantitative and qualitative survey within the UK and Ireland received 261 responses from parents of children. Differences were first suspected antenatally among 41% of respondents and in 57% postnatally, with 2% unsure. Of the children, 54% were seen in a clinic by a specialist congenital hand surgeon within 3 months and 88% within 12 months, with 73% of respondents feeling unsupported after a diagnosis that was unexpected. Qualitative analysis outlined a broad spectrum of parental concerns about the quality of information received, especially regarding the child's future biopsychosocial needs. This study showed the need for more support for parents from frontline healthcare professionals and the need for a streamlined referral pathway.Level of evidence: IV.

Burnout in ENT France: Update and risk factors; a STROBE analysis

BackgroundBurnout can significantly impact practitioners and their co-workers, and hence patients. There are no data for the prevalence of burnout in French ENT specialists, or for associated risk factors. Material and methodsA French national cross-sectional online survey was performed on the initiative of the ENT National Professional Council (CNPORL), contacting all ENT specialists whose e-mail address was known to the French Society of ENT, the National Professional Council or the National ENT Union. The 22-question Maslach Burnout Inventory (MBI) was sent out, along with 16 extra questions on possible risk factors. ObjectivesThe study sought to assess the prevalence and severity of burnout, using the MBI, and to analyze risk factors. ResultsAmong the 1936 physicians, 406 contacted responded to the questionnaire (21%). Mean age was 47±14 years (range, 25–77 years); 53% male, 47% female. 196 (48%) reported burnout, including 20 (5%) severe burnout. Independent risk factors for burnout of whatever severity, comprised social interaction issues, history of identified burnout, and medicolegal pressures. Social interaction issues were independently associated with specifically severe burnout. ConclusionsBurnout affected almost half of respondents. There are identifiable risk factors, for which improvements could be implemented.

COMPARATIVE ANALYSIS OF ATRIAL FIBRILLATION EPIDEMIOLOGY IN YOUNG ROMANIAN ADULTS IN SEPHAR II-IV SURVEYS

Objective: Atrial fibrillation (AF) is increasingly prevalent in all European countries, particularly in those strongly associated with high cardiovascular risk. We sought to evaluate AF epidemiology in Romanian adults recruited in three consecutive editions of the SEPHAR national survey (Study for Evaluation of Prevalence of Hypertension and Cardiovascular Risk in an Adult Population in Romania) aged eighteen to fifty years. Design and method: We performed a post-hoc analysis of 5422 subjects randomly recruited to ensure a nationally representative distribution by age, sex and area of residence during three consecutive editions of a cross-sectional national survey assessing hypertension epidemiology in Romania. AF prevalence and potentially contributing factors to AF burden were assessed in all subjects aged 18 to 50 years. The presence of AF was defined either by study EKG diagnosis or by documented medical history of AF. Results: There were 52.4% (n = 2845) subjects aged less than fifty years (mean 35.4 ± 8.64 years, 45.5% males, 57.5% from urban areas). AF prevalence was 1.7% (n = 49) and significantly increased throughout the study (1% (n = 11) vs. 1.6% (n = 17) vs. 3.3% (n = 21), p = 0.001). AF prevalence was similar in males vs. females (1.9% vs. 1.6%, p = 0.47) and in urban vs. rural areas (1.7% vs. 1.8%, p = 0.77). There was a two-fold higher prevalence in hypertensives vs. normotensives (2.8% vs. 1.4%, p = 0.01). AF was significantly more frequent in diabetic subjects (4.3% vs. 1.4%, p = 0.02). The mean CHA2DS2-VASc score was significantly higher in AF patients (1.32 ± 1.21, p &lt; 0.001) and was higher than 2 points in 49% (n = 24) of AF patients. Conclusions: Based on data stemming from three consecutive editions of SEPHAR, AF prevalence seems to have demonstrated a two-fold increase in Romanians aged less than fifty years and is significantly more frequent in diabetics and hypertensives.

Design, Methods, and Participation in Riksmaten Young Children—A Swedish National Dietary Survey

BackgroundNational dietary surveys provide essential data for risk benefit assessments of foods and nutrients, for management and policy development. Physical activity measurement and biomonitoring can provide important complementary data but are less commonly included. ObjectivesThis study aimed to describe the study design and methods of the cross-sectional Swedish national dietary survey Riksmaten Young Children (Riksmaten småbarn), of children aged 9 mo, 18 mo, and 4 y. Participation/dropout rates for the 2 older age groups are also presented. The impact of different recruitment strategies is discussed. MethodsChildren (N = 16,655) were randomly selected from the population register; invitations to guardians were sent by post and where possible, followed up by telephone. Food intake was assessed by a 2-d food diary and/or questionnaire. Height and weight were reported after measurement. Physical activity (accelerometery, 7 d) and stool, blood, and urine samples were assessed in subgroups. ResultsFood consumption data were collected in 1828 children (11% of the invited; 18 mo: n = 1078, and 4 y: n = 750). Of participants also in subgroups, 71% provided physical activity data (n = 1307), 60% stool samples (n = 630), and 51% blood and/or urine samples (n = 593). The study population represented all geographic regions and types of municipalities in Sweden, but participating households had both higher education level and higher income than the target population. Only minor differences were seen in participation rates between recruitment via post and telephone compared with those through post only (12% compared with 10%). Repeated contact attempts were needed for the majority of participants (65%). Despite the low-participation rate, 99% of the participants completed the study once started. ConclusionsAlthough it was a challenge to recruit participants, Riksmaten Young Children provides a substantial amount of information at national level, representative in terms of sex, geography, and family structure. The underrepresentation of households with lower socioeconomic position must be considered when generalizing results.
