Changes over time in population level transport satisfaction and mode of travel: A 13 year repeat cross-sectional study, UK

Abstract Background Smoking among Japanese adolescents has decreased noticeably. However, little is known whether the decreasing trend in adolescent smoking can be seen across all socioeconomic status (SES) groups. This study aimed to examine trends in socioeconomic inequalities in smoking among Japanese adolescents between 2008 and 2016. Methods We conducted a repeated cross-sectional study using data from three surveys of high school students in Okinawa, Japan, in 2008, 2012, and 2016. The study participants consisted of 7902 students in grades 10 through 12 (15–18 years). Smoking was assessed as current cigarette use. SES indicators included familial SES (parental education and family structure) and student’s own SES (school type). To evaluate absolute and relative inequalities, prevalence differences (PDs) and ratios (PRs) between low and high SES groups were estimated. The slope index of inequality (SII) and relative index of inequality (RII) were also calculated. Results Smoking prevalence among boys and girls significantly declined from 11.5% and 6.2% in 2008 to 4.7% and 1.9% in 2016, respectively. Similar decreasing trends in smoking were found among most of the SES groups. The PDs and SII for parental education in boys and family structure in girls decreased over time while those for school type persisted among boys and girls. The PRs and RII for school type in boys increased while those for other SES indicators among both sexes remained stable over time. Conclusions Smoking among Japanese adolescents has been declining and time trends of socioeconomic inequalities in smoking varied by absolute and relative measures. Further policies and/or interventions to reduce smoking inequalities should focus on the context of schools, especially in vocational high schools.

Introduction: There is a paucity of studies examining temporal trends in the incidence and mortality of moderate-to-severe hypoxic-ischemic encephalopathy (HIE) during the last decade of therapeutic hypothermia (TH). Methods: Multicenter cross-sectional study of all infants ≥35 weeks gestational age diagnosed with moderate-to-severe HIE within 6 h of birth in an extensive region of Spain between 2011 and 2019, in order to detect trend changes over time in the (1) annual incidence, (2) severity of neurological and systemic organ involvement, and (3) neonatal death from HIE. Results: Annual incidence rate of moderate-to-severe HIE was 0.84 (95% confidence interval [CI] 0.7–0.97) per 1,000 births, without trend changes over time (p = 0.8), although the proportion of severe HIE infants showed an average annual decline of 0.86 points (95% CI 0.75–0.98). There were 102 (70%) infants diagnosed with moderate HIE and 44 (30%) with severe HIE. TH was offered to 139/146 (95%) infants. Infants with clinical and/or electrical seizures showed a decreasing trend from 56 to 28% (p = 0.006). Mortality showed a nonstatistically significant decline (p = 0.4), and the severity of systemic damage showed no changes (p = 0.3). Obstetric characteristics remained unchanged, while higher perinatal pH values (p = 0.03) and Apgar scores (p = 0.05), and less need for resuscitation (p = 0.07), were found over time. Conclusion: The annual incidence of moderate-to-severe HIE has stabilized at around 1 per 1,000 births, with a temporal trend toward a decrease in severe HIE infants and a slight decline of mortality. No association was found between temporal trends and changes in perinatal/obstetric characteristics over time.

Backgi-ound Hepatitis B (HB) has been classified as moderate-tohighlyendemic in Indonesia. HB vaccination, the most effectivemethod to prevent HB viral transmission, induces protectiveantibodies against HB surface antigen (anti-HBs). However, theseantibodies decline in titer over time. Studies on the duration ofprotection and the prevalence of n on-responders in Indonesianadolescents have been limited.Objectives To determine anti-HBs titers in 15-17-year oldIndonesian adolescents given primary HB vaccine during infancyand the prevalence of non-responders after a HB vaccine boosterdosage.Methods This cross-sectional study was performed from Februaryto September 2008 on adolescents aged 15-17 years in threesenior high schools in Jakarta who received complete primary HBvaccines during infancy, based on parents' recall. Investigationsincluded HB vaccination history, anthropometric measurements,and blood tests for anti-HBs before and 4-6 weeks after a boosterdose ofHB vaccine.Results Of 94 subjects, 35 had protective anti-HBs and 59 hadundetectable anti-HBs. A booster dose was administered to 5 8 of then on-protected subjects, of which 33 showed anamnestic responses.However, 25 subjects failed to generate protective anti-HBs. Takinginto consideration the adolescents with protective anti-HBs beforeand after the booster dose, serologic protection was demonstratedin 73%. Non-responder prevalence was 27%. The high prevalenceof non-responders may indicate bias of parents' recall.Conclusion Protective anti-HBs is detected in less than half ofIndonesian adolescents given primary HB vaccine during infancy.Following booster dosage, anamnestic responses are n oted in onethirdof subjects. The prevalence of non-responders is 27%, butconfirmation with further study is needed.

Abstract Background While vaccine development is itself a challenge; ensuring optimal vaccine uptake at population level can present an even more significant challenge. Therefore, this study aimed to assess the Pakistani population’s attitude and preferences towards the Coronavirus disease 2019 (COVID-19) vaccine. Method A cross-sectional study was carried out through an online self-administered questionnaire from 27 September 2020 to 11 October 2020. A total of 883 people responded to the survey. The questionnaire included the participants’ socio-demographic variables, attitudes, beliefs towards the COVID-19 vaccine and acceptance and rejection of vaccination, and reasons for them. Logistic regression analysis was used to analyze the predictors for vaccine acceptance and willingness to pay for the vaccine. Results A majority (70.8%) of respondents will accept the COVID-19vaccine if available, and 66.8% showed a positive attitude towards vaccination. Monthly family income, education level, self-diagnosis of COVID-19 or a friend, family member, or colleague are significant factors influencing the acceptance of COVID-19 vaccination. The dogma of being naturally immune to COVID-19 was a key reason for the refusal of the vaccine. Less than half (48%) of those who refuse will vaccinate themselves if government officials have made it compulsory. A third (33.9%) of participants were willing to pay up to (7 USD) 1000 Pkr (Pakistani Rupees) for the vaccine. Conclusion The population’s positive attitude should be improved by increasing awareness and eradicating false myths about vaccines through large-scale campaigns.

Behavioural Aspects

Background - In recent years there has been a proliferation of alternative tobacco and nicotine products that reduce consumers’ exposure to harmful substances and therefore have the potential to reduce risk to health. Post-market surveillance enables the evaluation of newly introduced tobacco and nicotine products (aka potentially reduced risk products (PRRPs)) at a population level. This study aims to investigate tobacco and nicotine consumer demographics and discover how people are using these products, and characterise behavioral trends as transitions between tobacco heated products (THPs) and other nicotine products. These behavioural aspects, in conjunction with the intrinsic risk of the product, are essential for assessing the potential health effects and establishing a population risk assessment. Design and methods - This epidemiological cross-sectional study will collect data using a self-administered study instrument from the general Japanese population aged 20 years and older. The targeted sampling size is up to 5,000 participants per study wave. The study addresses the following objectives: estimation of tobacco and nicotine use prevalence; characterisation of product usage by product type; changes in use behaviour in general, with particular emphasis on the introduction of THPs in the time period of one year; risk perceptions of different tobacco products and no tobacco usage; and participant perceived health status and quality of life. Discussion - The description of tobacco and nicotine product use behaviour, the estimation of prevalence data, the measuring of product-specific risk perception and the change of tobacco use behaviour within one year will allow for a comprehensive assessment of the effect of introducing THPs into a market. These data could also be used to inform a system dynamics population model in order to estimate the public health impact of introducing a THP into the Japanese market.

Background This study aimed to describe oropharyngeal chlamydia (OCT) in gay and bisexually active men (GBM) attending a large urban sexual health clinic in Sydney and determine what proportion of cases would be missed if screening was not routine. Methods: Retrospective data were extracted for all GBM with a positive OCT result between 1 October 2012 and 31 April 2014. The control group consisted of patients who had a negative OCT result on their first visit during the study period, and each patient was only counted once. Results: A total of 74 of 2920 GBM (0.03, 95% CI: 0.02–0.03) were diagnosed with OCT. The 2920 GBM had a total of 11 226 OCT tests performed, demonstrating OCT test positivity of 0.006 (95% CI: 0.005–0.008). A total of 62 sexually transmissible infections (STIs) were diagnosed at other sites: 34 rectal chlamydia (CT), 12 throat gonorrohea (GC), 7 urine CT, 7 rectal GC, 1 infectious syphilis and 1 non-gonoccal urethritis (NGU) case. Of the 74 OCT cases, 56 (0.76, 95% CI: 0.64–0.85) were treated with Azithromycin; 51 (69%) as part of standard treatment for their STI co-infection (34 rectal CT, 12 throat GC, 7 urine CT, 7 rectal GC, 1 NGU case) and a further five (7%) were treated as contacts. The remaining 18 people (0.24, 95% CI: 0.15–0.36) would not have been treated unless they were tested specifically for OCT. Conclusion: Overall, two-thirds of the OCT cases received appropriate treatment and only a small number of cases would have been missed had routine screening not been performed. With an extremely low overall test positivity of 0.6%, screening for OCT at our service adds little to population level health control.

Abstract The aim of this study was to describe and compare findings regarding the prevalence and severity of dental caries when using ICDAS and DMFT/dmft in an epidemiological study with children and their mothers. This cross-sectional study evaluated 150 preschoolers and their mothers. Data were collected with ICDAS and then transformed into DMFT/dmft. ICDAS scores related to caries were analyzed according to three different cut-off-points: CP1 (0-healthy/1-6-caries), CP2 (0-1-healthy/2-6-caries) and CP3 (0-2-healthy/3-6-caries), representing the D/d of DMFT/dmft. ICDAS codes regarding restorations, except sealants, were considered the F/f and the code 97 as the M/m of DMFT/dmft index. Prevalence of caries and its severity with ICDAS were 92%, 84% and 31.3% in children and 97.3%, 96.6% and 80% in adults according to CP1/CP2/CP3, respectively. Admitting CP3 as the standard for data transformation of ICDAS in DMFT/dmft, it was observed that DMFT/dmft index would underestimate 60% of non-cavitated lesions in children and 16.6% in adults. The DMFT/dmft underestimated the presence of disease to disregard non-cavitated lesions for the pediatric population evaluated. The choice of which is the best index for epidemiological surveys will depend on the purpose of the research and the target population: if it is to estimate the needs of the population to determine clinical care in children and adults, the DMFT/dmft may be sufficient. However, if the objective is to have a more comprehensive diagnosis of caries at the population level in order to develop preventive strategies, to halt and reverse the disease, the detection of non-cavitated-lesions becomes important, mainly in young children.

Over Time

Despite the recent proliferation of price transparency tools, consumer use and awareness of these tools is low. Better strategies to increase the use of price transparency tools are needed. To inform such efforts, we studied who is most likely to use a price transparency tool. We conducted a cross-sectional study of use of the Truven Treatment Cost Calculator among employees at 2 large companies for the 12 months following the introduction of the tool in 2011-2012. We examined frequency of sign-ons and used multivariate logistic regression to identify which demographic and health care factors were associated with greater use of the tool. Among the 70 408 families offered the tool, 7885 (11%) used it at least once and 854 (1%) used it at least 3 times in the study period. Greater use of the tool was associated with younger age, living in a higher income community, and having a higher deductible. Families with moderate annual out-of-pocket medical spending ($1000-$2779) were also more likely to use the tool. Consistent with prior work, we find use of this price transparency tool is low and not sustained over time. Employers and payers need to pursue strategies to increase interest in and engagement with health care price information, particularly among consumers with higher medical spending.
