ObjectivesTo investigate whether the high rates of caesarean sections (CSs) in Brazil have impacted on the prevalence of preterm and early-term births.DesignIndividual-level, cross-sectional analyses of a national database.SettingAll hospital births occurring in the country in 2015.Participants2 903 716 hospital-delivered singletons in 3157 municipalities, representing >96% of the country’s births.Primary and secondary outcome measuresCS rates and gestational age distribution (<37, 37–38, 39–41 and 42 or more weeks’ gestation). Outcomes were analysed according to maternal education, measured in years of schooling and municipal CS rates. Analyses were also adjusted for maternal age, marital status and parity.ResultsPrevalence of CS was 55.5%, preterm prevalence (<37 weeks’ gestation) was 10.1% and early-term births (37–38 weeks of gestation) represented 29.8% of all births, ranging from 24.9% among women with <4 years of schooling to 39.8% among those with >12 years of education. The adjusted prevalence ratios of preterm and early-term birth were, respectively, 1.215 (1.174–1.257) and 1.643 (1.616–1.671) higher in municipalities with≥80% CS compared with those <30%.ConclusionsBrazil faces three inter-related epidemics: a CS epidemic; an epidemic of early-term births, associated with the high CS rates; and an epidemic of preterm birth, also associated with CS but mostly linked to poverty-related risk factors. The high rates of preterm and early-term births produce an excess of newborns at higher risk of short-term morbidity and mortality, as well as long-term developmental problems. Compared with high-income countries, there is an annual excess of 354 000 preterm and early-term births in Brazil.

ObjectivesThis study aimed to explore the cognitive development of low-risk children during early childhood for early-term births at 37 and 38 weeks of gestation compared with full term births at 39–41 weeks of gestation.Setting and participantsWe conducted a cross-sectional study in Shanghai, one of the largest cities in China. A total of 1444 children from singleton pregnancies born at term gestation were included in the study.MeasuresThe cognitive outcomes of the subjects were measured using the cognitive subtest of Bayley Scales of Infant and Toddler Development, Third Edition (BSID-III) across three cities in China. We analysed the association between gestational age and cognitive development during infancy and toddler stages using multivariate linear modelling.ResultsThe cognitive development scores for infants born at 37 gestational weeks were significantly lower than those born at 39–41 gestational weeks (β=−2.257, 95% CI −4.280 to −0.235; p<0.05) after adjusting for children’s and maternal characteristics, as well as socio-economic factors. However, there were no significant differences in cognitive ability between infants born at 38 gestational weeks compared with their full-term counterparts (p>0.05). Moreover, these effects were not found in toddlers (between 17 and 48 months of age) after adjusting for the possible confounders (p>0.05).ConclusionsInfants born at 37 weeks of gestation exhibited weaker cognitive ability compared with those born at 39–41 weeks of gestation. Our findings provide evidences for the close monitoring of potential developmental problems in early-term children, especially those born at 37 gestational weeks.

ObjectivesTo explore the efficacy of machine learning (ML) techniques in predicting under-five mortality (U5M) in low-income and middle-income countries (LMICs) and to identify significant predictors of U5M.DesignThis is a cross-sectional, proof-of-concept study.Settings and participantsWe analysed data from the Demographic and Health Survey. The data were drawn from 34 LMICs, comprising a total of n=1 520 018 children drawn from 956 995 unique households.Primary and secondary outcome measuresThe primary outcome measure was U5M; secondary outcome was comparing the efficacy of deep learning algorithms: deep neural network (DNN); convolution neural network (CNN); hybrid CNN-DNN with logistic regression (LR) for the prediction of child’s survival.ResultsWe found that duration of breast feeding, number of antenatal visits, household wealth index, postnatal care and the level of maternal education are some of the most important predictors of U5M. We found that deep learning techniques are superior to LR for the classification of child survival: LR sensitivity=0.47, specificity=0.53; DNN sensitivity=0.69, specificity=0.83; CNN sensitivity=0.68, specificity=0.83; CNN-DNN sensitivity=0.71, specificity=0.83.ConclusionOur findings provide an understanding of determinants of U5M in LMICs. It also demonstrates that deep learning models are more efficacious than traditional analytical approach.

ObjectivesThis study aimed to investigate the factors associated with low birth weight (LBW) in Afghanistan.DesignCross-sectional study.SettingThis study used data collected from the Afghanistan Demographic and Health Survey 2015.ParticipantsFacility-based data from 2773 weighted live-born children enrolled by a two-stage sampling strategy were included in our analysis.Primary and secondary outcome measuresThe primary outcome was LBW, defined as birth weight <2.5kg.ResultsOut of 2773 newborns, 15.5% (n=431) had LBW. Most of these newborns were females (58.3%, n=251), had a mother with no formal schooling (70.5%, n=304), lived in urban areas (63.4%, n=274) or lived in the Central region of Afghanistan (59.7%, n=257). In multivariable analysis, residence in Central (adjusted OR (AOR): 3.4; 95% CI 1.7 to 6.7), Central Western (AOR: 3.0; 95% CI 1.5 to 5.8) and Southern Western (AOR: 4.0; 95% CI 1.7 to 9.1) regions had positive association with LBW. On the other hand, male children (AOR: 0.5; 95% CI 0.4 to 0.8), newborns with primary maternal education (AOR: 0.5; 95% CI 0.3 to 0.8), birth interval ≥48 months (AOR: 0.4; 95% CI 0.1 to 0.8), belonging to the richest wealth quintile (AOR: 0.2; 95% CI 0.1 to 0.6) and rural residence (AOR: 0.3; 95% CI 0.2 to 0.6) had decreased odds of LBW.ConclusionsMultiple factors had association with LBW in Afghanistan. Maternal, Neonatal and Child Health programmes should focus on enhancing maternal education and promoting birth spacing to prevent LBW. To reduce the overall burden of LBW, women of the poorest wealth quintiles, and residents of Central, Central Western and South Western regions should also be prioritised. Further exploration is needed to understand why urban areas are associated with higher likelihood of LBW. In addition, research using nationally representative samples are required.

ObjectivesTo assess the trend and decompose the determinants of delivery with no one present (NOP) at birth with an in-depth subnational analysis in Nigeria.DesignCross-sectional.SettingNigeria, with five waves of nationally representative data in 1990, 2003, 2008, 2013 and 2018.ParticipantsWomen with at least one childbirth within 5 years preceding each wave of data collection.Primary and secondary outcome measuresThe outcome of interest is giving birth with NOP at delivery defined as childbirth assisted by no one. Data were analysed using Χ2 and multivariate decomposition analyses at a 5% significance level.ResultsThe prevalence of having NOP at delivery was 15% over the studied period, ranges from 27% in 1990 to 11% in 2018. Overall, the prevalence of having NOP at delivery reduced significantly by 35% and 61% within 2003–2018 and 1990–2018, respectively (p<0.001). We found wide variations in NOP across the states in Nigeria. The highest NOP practice was in Zamfara (44%), Kano (40%) and Katsina (35%); while the practice was 0.1% in Bayelsa, 0.8% in Enugu, 0.9% in Osun and 1.1% in Imo state. The decomposition analysis of the changes in having NOP at delivery showed that 85.4% and 14.6% were due to differences in women’s characteristics (endowment) and effects (coefficient), respectively. The most significant contributions to the changes were the decision-maker of healthcare utilisation (49%) and women educational status (24%). Only Gombe experienced a significant increase (p<0.05) in the level of having NOP between 2003 and 2018.ConclusionA long-term decreasing secular trend of NOP at delivery was found in Nigeria. NOP is more prevalent in the northern states than in the south. Achieving zero prevalence of NOP at delivery in Nigeria would require a special focus on healthcare utilisation, enhancing maternal education and healthcare utilisation decision-making power.

ObjectivesHealth disparities in schizophrenia are well established. However, it is less understood whether area-level socioeconomic status (SES) is differentially associated with schizophrenia depending on individual-level SES. Therefore, using a nationally large representative data, this study investigated the association between individual-level SES, area-level SES and their interaction with schizophrenia in Chinese adults from a multilevel perspective.SettingHousehold interviews in 734 counties (districts), 2980 towns (streets) and 5964 communities (villages) from 31 provinces, People's Republic of China, as part of the cross-sectional survey of Second China National Sample Survey on Disability.Participants1 909 205 men and women aged 18 years old and above.Primary and secondary outcome measuresA screen followed by clinical diagnosis was used to identify schizophrenia, and schizophrenia was ascertained according to the International Statistical Classification of Diseases, 10th Revision (code F20).Results1-SD increase in individual SES was associated with decreased risk of schizophrenia (OR=0.45,95% CI0.43 to 0.46). 1-SD increase in area-level SES was associated with increased risk of schizophrenia (OR=1.30,95% CI1.24 to 1.37). The interaction of individual SES and area-level SES was statistically significant (OR=1.05,95% CI1.02 to 1.08); as the level of area SES increased, schizophrenia risk of lower SES people grew faster than the risk of higher SES people.ConclusionsArea-level SES is particularly important to mental health of low SES individuals, with low SES people in high SES counties having the highest risk of schizophrenia than other groups. Action to reduce SES disparities in schizophrenia will require attention to the area-level context of low SES adults.

AbstractObjectiveThis study aimed to investigate the frequency of overweight and obesity among Iranian adolescent girls aged 14–17 years and its possible association with maternal education in Rasht city in 2005.DesignA cross-sectional survey on 1054 schoolgirls.SettingHigh schools in Rasht city, Iran.MethodsA multistage sampling method was used and 1054 randomly selected schoolgirls were studied. Data on age and mother's years of schooling were collected by questionnaire and body weight and height were measured. Overweight and obesity were defined using age- and sex-specific body mass index (BMI) cut-off points proposed by the International Obesity Task Force (IOTF), and compared with 85th and 95th BMI percentile curves of the IOTF reference population, respectively. Data analyses included two groups based on mother's years of schooling: less educated ( < 12 years) and more educated ( ≥ 12 years).ResultsThe overall prevalence of overweight and obesity in this population was 21.9 and 5.3%, respectively. Results of logistic regression analysis showed that the risk of overweight was higher for lower age group (odds ratio = 2.0, 95% confidence interval 0.18–3.09). Overweight was more common in girls with less educated mothers than in girls with more educated mothers (26.0 vs. 19.8%, P = 0.03).ConclusionThese data indicate that overweight is highly prevalent among adolescent girls, especially in lower social groups in Rasht, and the rate is exceeding those reported in other parts of the country. Preventive strategies need to be adopted to combat the epidemic of overweight and obesity in this population.

ObjectiveTo assess the prevalence of and factors associated with depression among adolescent boys and girls.DesignWe conducted a nationwide cross-sectional study.SettingThis study was carried out in 82 randomly selected clusters (57 rural, 15 non-slum urban and 10 slums) from eight divisions of Bangladesh.ParticipantsWe interviewed 4907 adolescent boys and 4949 adolescent girls.Primary and secondary outcome measuresThe primary outcome measure was ‘any depression’ and the secondary outcome measures were types of depression: no or minimal, mild, moderate, moderately severe and severe.ResultsThe overall prevalence of no or minimal, mild, moderate, moderately severe and severe depression was 75.5%, 17.9%, 5,4%, 1.1% and 0.1%, respectively. Across most of the sociodemographic, lifestyle and anthropometric strata, the prevalence of any depression was higher among adolescent girls. In both sexes, depression was associated with higher age, higher maternal education, paternal occupation e.g., business, absence of a 6–9-year-old member in the household, food insecurity, household consumption of unfortified oil, household use of non-iodised salt, insufficient physical activity (adjusted odds ratio, AOR: 1.24 for boys, 1.44 for girls) and increased television viewing time e.g., ≥121 minute/day (AOR: 1.95 for boys, 1.99 for girls). Only among boys, depression was also associated with higher paternal education e.g., complete secondary and above (AOR: 1.42), absence of another adolescent member in the household (AOR: 1.34), household use of solid biomass fuel (AOR: 1.39), use of any tobacco products (AOR: 2.17), and consumption of processed food (AOR: 1.24). Only among girls, non-slum urban residence, Muslim religion, and household size ≤4 were also associated with depression.ConclusionThe prevalence of depression among adolescent boys and girls is high in Bangladesh. In most sociodemographic, lifestyle and anthropometric strata, the prevalence is higher among girls. In this age group, depression is associated with a number of sociodemographic and lyfestyle factors. The government of Bangladesh should consider these findings while integrating adolescent mental health in the existing and future programmes.

Background & Aims: A number of factors have been identified that influence the yield of screeningcolonoscopy. The perceived tolerability of bowel preparation has not been studied as a predictor of quality outcomes in colonoscopy. We aimed to characterize the association between patient-perceived tolerability of bowel preparation and polyp detection during colonoscopy.Methods: We performed a cross-sectional cohort study of 413 consecutive adult patients presenting foroutpatient colonoscopy at two outpatient endoscopy centers at our institution. We developed a standardized questionnaire to assess the patient's experience with bowel preparation. Bowel preparation quality was measured using the validated Ottawa scale and colonoscopic findings were recorded for each patient. The primary outcome was polyp detection and the secondary outcome was the quality of bowel preparation.Results: Patient-reported clarity of effluent during bowel preparation correlated poorly with Ottawa score during colonoscopy, k=0.15. Female gender was an independent risk factor for a poorly tolerated bowel prep (OR 3.93, 95% CI 2.30 - 6.72, p<0.001). Report of a poorly tolerated bowel prep was independently associated with the primary outcome, polyp detection (OR 0.39, 95% CI 0.18 - 0.84, p=0.02) and also with the secondary outcome, lower quality bowel preparation (OR 2.39, 95% CI 1.17 - 4.9, p=0.02).Conclusions: A patient-perceived negative experience with bowel preparation independently predicted both a lower quality bowel preparation and a lower rate of polyp of detection. Assessment of the tolerability of bowel preparation before colonoscopy may be a clinically useful predictor of quality outcomes during colonoscopy.

ABSTRACT Prenatal care is health care by health personnel to care the pregnant according to standards. Worlrd Health Organization (WHO) estimates more than 500.000 women die during pregnancy or childbirth. Maternal mortality in Indonesia is 307 per 100,000 live births. The quantity of pregnant women’s visit in Kabupaten Banyuasin in 2009 of 89.1%. The purpose of this study to determine the relationship between education and occupation with prenatal care at Puskesmas Mariana  Kecamatan Banyuasin I Kabupaten Banyuasin in 2011. This study uses analytic approach survey by Cross Sectional methods, the population are 1.946 pregnant women and the samples as many as 332 people. The results of univariate analysis study of pregnant women who are higher education as much as 45.2%, and  low maternal education as much as 54.8%. In pregnant women who work of 43.4%, and pregnant women who do not work for 56.6%. From the results of bivariate analysis and Chi-Square statistical tests found a significant association between education of pregnant women with prenatal care with P Value = 0.000, and there was a significant association between occupation of pregnant women with prenatal care with P Value = 0.000. Can be concluded that there is a relationship between education and occupation of pregnant women with prenatal care. Expected to health workers to provide counseling on the importance of prenatal care in pregnant women and expected future studies may explore again the factors associated with prenatal care with the different variables.   ABSTRAK Pemeriksaan kehamilan adalah pelayanan kesehatan oleh tenaga kesehatan untuk memeriksakan ibu hamil sesuai standar. World Health Organization (WHO) memperkirakan lebih dari 500.000 ibu pertahunnya meninggal saat hamil atau bersalin. AKI di Indonesia 307 per 100.000 kelahiran hidup.

BACKGROUND Importance: Positive patient experiences are associated with illness recovery and adherence to medication. The shift toward virtual visits creates a need to understand the opportunities and challenges in providing a patient experience that is at least as positive as in-person visits. OBJECTIVE To evaluate the virtual care experience for patients with Covid-19 as their chief complaints. METHODS We conducted a cross-sectional study of the first cohort of patients with Covid-19 concerns in a virtual clinic. We collected data on all virtual visits between March 20-29, 2020. Outcomes: The main endpoints of this study were patient diagnosis, prescriptions received, referrals, wait time and duration, and satisfaction. The secondary outcome was the reported choice of alternative care options. RESULTS Of the 358 total virtual visits, 42 patients marked “Covid-19 Concern” as their chief complaint. Of those patients, 23 (54.8%) female patients, the average age of patients was 33.9 years, and 41 (97.7%) patients were seeking care for themselves and one (3.3%) visit was for a dependent. For all virtual visits, the average wait time (SD) was 157.2 (181.7) minutes and the average wait time (SD) for Covid-19 Concern visits was 177.4 (186.5) minutes. Covid-19 Concern phone visits had an average wait time (SD) of 180.1 (187.2), compared to 63.4 (34.4) minutes for Covid-19 Concern video visits. Thirteen (65%) patients rated their provider as “Excellent” with similar proportions among phone (64.3%) and video (66.7%). CONCLUSIONS This study evaluated the virtual experiences of patients with Covid-19 concerns. There were different experiences for patients depending on their choice of communication. Long wait times were a major drawback in the patient experience. We have learned from evaluating the experience of our first cohort of Covid-19 Concern patients.
