Big Data in Epidemiology: Brave New World?

Epidemiology is experiencing a significant shift toward the utilization of big data for health monitoring and decision-making. This article discusses the recent example of the World Health Organization (WHO) global oral health status report and regional summaries, which faced criticisms due to its reliance on big data from the Global Burden of Disease (GBD) study. We address the arguments for and against the use of big data in epidemiology and provide an assessment of the value and limitations of big data epidemiology. Moreover, we provide recommendations as to how the oral health community should reconcile traditional epidemiologic approaches with big data and advanced data analytics. This Perspective article highlights the challenges of the current epidemiologic landscape, the potential of big data, and the need for a balanced approach to data utilization in epidemiology.

An insight from National Family Health Surveys on changing trends in prevalence and knowledge regarding T.B. in India.

BACKGROUND/OBJECTIVES: Addressing gaps in knowledge about T.B. is a vital component of T.B.'s elimination to achieve the End T.B. strategy by 2025 in India. The present study compares the correct knowledge regarding T.B. by analysis of the nationally-representative secondary data of NFHS-4 (2015-16) and NFHS-5 (2019-20) data in India. METHODS: NFHS-4 and NFHS-5 secondary data on eleven T.B.-related questions analysis was done after seeking permission to use datasets from the Demographic and Health Surveys (DHS) program-sociodemographic details and Responses exported and analysed using M.S. Excel. Descriptive variables were represented as frequency and percentages. Z tests for proportions were used to compare and determine differences between NFHS-4 and NFHS-5 knowledge. Statistical significance was set at a p-value of <0.05. RESULTS: The correct knowledge regarding T.B. significantly rose from 457,399 (56.3%) in NFHS-4 to 507,517 (61.4%) in NFHS-5. However, a significant increase in incorrect knowledge about the other modes of transmission of T.B. and T.B. courtesy stigma in households from 95,985 (13.4%) in 2015-16 to 113,978 (14.9%) in 2019-20 was observed. CONCLUSIONS: The correct knowledge of T.B. has significantly increased from NFHS-4 (2015-16) to NFHS-5 (2019-20). However, there is a significant increase in incorrect knowledge regarding the modes of transmission and stigmatising attitudes towards T.B. through improvement in the communication efforts in the National T.B. Elimination Programme (NTEP).

Alcohol habits and alcohol-related health conditions of self-defined lifetime abstainers and never binge drinkers.

BACKGROUND: Prior research has shown that using lifetime abstainers as the reference group to examine the association between alcohol use and health-related consequences has several disadvantages. The aim of the present study was to examine the consistency of self-reported lifetime abstention and never-binge drinking, respectively, using national, longitudinal data collected in 2019 and 2020. Additionally, the prevalence of alcohol-related morbidity among lifetime abstainers was examined by linking survey data to alcohol-related morbidity data in a national patient register. METHODS: Data come from the Danish Health and Wellbeing Survey in 2019 and from a follow-up survey of the same individuals in 2020. A random sample of 14,000 individuals aged 15 years or older was drawn in mid-August 2019. Data were collected between September and December 2019. All those who were invited to the survey in 2019 and who were still alive and living in Denmark were invited to participate in a follow-up survey in 2020. Data in both waves were collected by self-administered questionnaires. Both questionnaires included the standard questions on alcohol consumption from the European Health Interview Survey model questionnaire. Information on alcohol-related morbidity was obtained from the Danish National Patient Register. RESULTS: In all, 5000 individuals completed the questionnaire in both waves. Approximately half (44.4%) of the individuals who declared that they were lifetime abstainers in 2020 (n = 252) had reported in 2019 to have drunk at some point in their life. Moreover, 39.7% contradicted earlier reported binge drinking. Furthermore, 2.4% of the respondents who defined themselves as lifetime abstainers in 2020 had earlier been diagnosed with an alcohol-related health condition. CONCLUSION: The present research reaffirms previous studies which have found self-reported lifetime abstainers to be unreliable as a consistent reference group. Additionally, the results indicated that a non-negligible proportion of lifetime abstainers had been diagnosed with an alcohol-related health condition.

Knowledge of and attitude towards depression among urban and rural residents in Beijing: a cross-sectional study.

OBJECTIVES: To compare the level of knowledge of depression, recognition ability and attitudes towards depression among urban and rural residents in Beijing. DESIGN: A cross-sectional study. SETTING: Six districts in Beijing, China, 2021. PARTICIPANTS: A total of 6463 participants aged 18 years and above who had lived for more than 6 months over the last year in Beijing were selected in this study. OUTCOME: The awareness and recognition of depression and the views of residents towards people with depression. RESULTS: A total of 2554 urban and 2043 rural residents completed the survey. Urban residents of Beijing exhibited a higher average total score on the Depression Knowledge Questionnaire [(20.4±3.3) vs (18.7±3.5), p<0.001] and a higher rate of correctly identifying individuals with depression (47.9% vs 36.6%, p<0.001) than their counterparts in rural areas. Residents who correctly identified people with depression had higher scores on the Depression Knowledge Questionnaire. Depression knowledge varied significantly among urban and rural residents. The multivariate linear regression analysis revealed that rural residents scored significantly lower on measures of depression knowledge compared with urban residents (B=-0.83, 95%CI=-1.03 to -0.63, p<0.001). Older individuals (aged 50+) showed lower understanding compared with the 18-49 age group, with significant negative regression coefficients (Urban: B=-1.06, Rural: B=-1.35, both p<0.001). Higher educational levels were positively associated with greater depression knowledge (Urban: B=1.40, Rural: B=1.21, both p<0.001). Employment was linked to higher knowledge levels than unemployment (Urban: B=-0.60, Rural: B=-0.58, both p=0.00). A monthly income of 8000 yuan or more correlated with better depression understanding than lower incomes (Urban: B=0.81, Rural: B=1.04, both p<0.001). Additionally, in urban areas, unmarried residents scored higher in depression knowledge than those divorced (B=-0.55, p=0.04). Residents in urban areas had relatively positive attitudes towards individuals with depression. CONCLUSIONS: Rural residents of Beijing had lower levels of knowledge and recognition of depression and more negative attitudes towards individuals with depression than those from urban areas. The health authority needs to focus on the poor level of knowledge and increase mental health resources in rural areas as a priority site for future psychological popularisation efforts.

Acceptability and timing considerations when administering patient-reported outcome measures (PROMs) among people with chronic health conditions who are culturally and linguistically diverse (CALD): a qualitative study protocol.

INTRODUCTION: Patient-reported outcome measures (PROMs) are validated and standardised questionnaires that capture patients' own reports of their symptoms, functioning and well-being. PROMs can facilitate communication between patients and clinicians, reduce symptom burden, enhance quality of life and inform health service re-design. We aim to determine the acceptability of PROMs and the preferred timing of PROM completion in New South Wales (NSW) at the point of care, facilitated by the Health Outcomes and Patient Experiences (HOPE) platform. METHODS AND ANALYSIS: Semi-structured interviews with patients (~50-75, sampling across seven language groups and seven clinical cohorts), carers (~10-20) and clinicians (~18) enrolled in HOPE will be conducted via videoconference, telephone or in person. Participants will be asked questions about (1) what makes PROMs acceptable for use in chronic disease management (2) when patients would prefer to complete PROMs and when clinicians would like to use PROMs for clinical decision-making and (3) factors that impede the acceptability of PROMs for culturally and linguistically diverse patients. Interviews will be analysed using a reflexive thematic approach, guided by Normalisation Process Theory. ETHICS AND DISSEMINATION: Ethics approval has been obtained from the Sydney Local Health District Human Research Ethics Committee (SLHD HREC, Study Protocol #X24-0138). Results will be published in appropriate peer-reviewed journals, presented at conferences, disseminated to participants in the form of a plain language summary, and widely disseminated to consumer groups and professional stakeholders.

Association between history of interparental violence and alcohol abuse among reproductive-age women: Evidence from the Peruvian Demographic and Health Survey.

BACKGROUND: Exposure to domestic violence by triggering repetitive distress and fear can affect neurodevelopmental and mental health in the short and long term. This, in turn, has been linked to an increased risk of substance abuse, such as alcohol abuse in adulthood. OBJECTIVE: The present study aimed to evaluate the association between exposure to violence from the father toward the mother and alcohol abuse in Peruvian women. DESIGN: Cross-sectional study. METHODS: We conducted a secondary analysis of data from the Peruvian Demographic and Family Health Survey (ENDES) of 2019. A total of 19,980 reproductive-aged women (15-49 years old) were surveyed using the Health Questionnaire during 2019. The dependent variable of the study was alcohol abuse, collected through self-report, according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria. Intimate partner violence (IPV; violence perpetrated by the father against the mother) was considered as the exposure variable. To assess the association of interest, we only considered observations with complete data and used binary logistic regression models, calculating crude odds ratios and adjusted odds ratios (aOR). For the multivariable model, we adjusted for confounding variables (age, marital status, education level, wealth index, ethnicity, residence, current smoker, depression, and IPV). RESULTS: We analyzed a final sample of 9953 women. The prevalence of interparental violence and alcohol abuse was 41.3% and 1.5%, respectively. We found that interparental violence was associated with higher odds of alcohol abuse (aOR: 2.10; 95% CI: 1.03-4.28) after adjusting for age, marital status, education level, wealth level, ethnicity, area of residence, current smoking, depression, and IPV. CONCLUSION: We identified that women of reproductive age who have been exposed to interparental violence were at higher odds of experiencing alcohol abuse issues.

Understanding the link between witnessing parental violence and alcohol abuse in Peruvian womenWitnessing violence between parents during childhood can leave deep emotional scars. This study explores whether such experiences are related to alcohol abuse among Peruvian women in their adult years. Using data from a national health survey in Peru, the experiences of nearly 20,000 women were analyzed to determine if witnessing violence between their parents during childhood was linked to alcohol problems later in life. Responses from the 2019 Peruvian Demographic and Family Health Survey were examined, focusing on women's reports of childhood exposure to violence between parents and current alcohol abuse, controlling for factors like age, education, and mental health. The study found that women who witnessed their parents engaging in violence were more likely to abuse alcohol as adults. About 41% of the women reported seeing such violence, and of these, a higher proportion struggled with alcohol compared to those who did not witness violence. Understanding the link between childhood experiences and adult behaviors can help develop targeted interventions to prevent alcohol abuse. This research highlights the need for support systems that help women cope with the emotional impacts of childhood trauma, potentially reducing alcohol-related problems in the future.

Epidemiology of overweight in under-five children in India: insights from National Family Health Survey.

Childhood overweight is not only an immediate health concern due to its implications but also significantly increases the risk of persistent obesity and consequently CVD in the future, posing a serious threat to public health. The objective of this study was to examine the trends and associated factors of childhood overweight in India, using nationally representative data from three rounds of the National Family Health Survey (NFHS). For the primary analysis, we used data from 199 375 children aged 0-59 months from fifth round of the NFHS (NFHS-5). Overweight was defined as BMI-for-age Z (BMI Z) score > +2 sd above the WHO growth standards median. We compared the prevalence estimates of childhood overweight with third round of the third round of NFHS and fourth round of the NFHS. Potential risk factors were identified through multiple logistic regression analyses. The prevalence of overweight increased from 1·9 % in third round of NFHS to 4·0 % in NFHS-5, a trend seen across most states and union territories, with the Northeast region showing the highest prevalence. The BMI Z-score distributions from the latest two surveys indicated that the increase in overweight was substantially larger than the decrease in underweight. The consistent upward trend in the prevalence across different demographic groups raises important public health concerns. While undernutrition rates have remained relatively stable, there has been a noticeable rise in the incidence of overweight during the same time frame. The increasing trend of overweight among children in India calls for immediate action.

Alignment of parent-proxy report and teen self-report of adverse childhood experiences among U.S. teens.

PURPOSE: Data on adverse childhood experiences (ACEs) among teens is collected using a single informant, a parent-proxy, or teen self-report. Little is known about alignment between these approaches. METHODS: Surveys were administered online to teens ages 15-17 and their parents (n = 522 dyads) using the AmeriSpeak panel. We present descriptive statistics on the prevalence and measures agreement for 18 ACEs based on teen self-report and parent-proxy report. We fit multivariable models examining associations between teen and household demographic characteristics and discordance in ACE report. RESULTS: Based on teen-self report and parent-proxy report, cumulative and individual ACE prevalence was overall similar. However, discordance was found in individual ACE reports within teen-parent dyads (discordance ranged: 2.9-21.2 %). Lowest agreement was among ACEs related to abuse, neglect, and violence victimization and highest among household challenges. Furthermore, parent-teen dyads with LGB+ youth (vs. heterosexual) and Black, Hispanic, and multiracial or another race (vs. White) youth were more likely to have discordant responses among several ACEs. CONCLUSIONS: Surveillance and programmatic efforts should consider the type of ACE and the reporter when using data to inform prevention strategies. Teen self-report for abuse, neglect, and violence victimization and community challenges ACEs are particularly important to capture.

Socioeconomic Status and Health Outcomes in Malaysian Adults: Findings From the National Health and Morbidity Survey (NHMS).

The relationship between socioeconomic status (SES) and health outcomes has garnered significant attention. However, there is a limited amount of research exploring the association between SES and the risk of metabolic syndrome in Malaysian adults. This study aims to determine the association between SES and risk of hypertension, diabetes and obesity. By using data from the National Health and Morbidity Survey (NHMS), SES was derived through principal component analysis involving six variables. Two different SES components were identified and labeled as "social status" and "wealth status." Among the participants, 36% were diagnosed with hypertension, 18% with obesity, and 21% with diabetes. Adults with high wealth and social status showed a significantly increased risk of obesity. Meanwhile, high social status was significantly associated with a reduction in the risk of hypertension and diabetes. A comprehensive understanding of the associations between SES and noncommunicable diseases could facilitate initiatives that promote healthy lifestyle behaviors, thereby enhancing the holistic well-being of Malaysians.

Decrease in Socioeconomic Disparities in Self-Rated Oral Health among Brazilian Adults between 2013 and 2019: Results from the National Health Survey.

This cross-sectional study assessed the magnitude of inequalities in self-rated oral health (SROH) among different socioeconomic groups in Brazil. Secondary data from interviews with a sample of adults (≥18 years) from the national health survey 2013 (n = 64,308) and 2019 (n = 88,531) were analyzed. Positive SROH was considered when participants selected the good or very good options. Socioeconomic indicators were monthly household income and years of education. The magnitude of inequalities among socioeconomic groups was estimated using the Slope (SII) and Relative Index of Inequality (RII). Interaction term assessed changes in SII/RII over time. Estimates were adjusted for sex and age. The prevalence of SROH was 67.50% in 2013 and 69.68% in 2019. Individuals with lower socioeconomic indicators had a lower prevalence of positive SROH. Significant reductions in the magnitude of the education-based RII between 2013 (1.58) and 2019 (1.48) in Brazil, as well as in north (1.70; 1.45) and northeast (1.50; 1.41) regions and reduction in the income-based RII in the north (1.71; 1.51) were observed. Socioeconomic inequalities in SROH persist across different Brazilian regions, although there was a reduction in disparities among education groups in 2019 compared with 2013. The findings of this study suggest that equitable Brazilian oral health policies may have contributed to reducing SROH inequality over time.

Potential impact of alcohol calorie labelling on the attitudes and drinking behaviour of hazardous and low-risk drinkers in England: a national survey.

OBJECTIVES: We investigated the hypothetical impact of mandatory alcohol calorie labelling, comparing non-drinkers, low-risk and hazardous drinkers in terms of attitudes, knowledge about calorie content and hypothetical behaviour changes should labelling be introduced. DESIGN: Cross-sectional national telephone survey. SETTING: Community-dwelling adults in England between November 2022 and January 2023. PARTICIPANTS: Data were collected from 4683 adults >18 years, of whom 24.7% were non-drinkers; 77.6% of alcohol drinkers were categorised as low-risk and 22.4% as hazardous drinkers according to the Alcohol Use Disorders Identification Test questionnaire. PRIMARY OUTCOME MEASURES: Attitudes to alcohol calorie labelling in shops and supermarkets and in hospitality venues, knowledge of the calorie content of alcoholic beverages (beer, wine, cider and spirits) and changes in drinking practices if calorie labelling was introduced. RESULTS: Comparisons were made between non-drinkers, low-risk drinkers and hazardous drinkers, with analyses adjusted for age, gender, ethnicity, socioeconomic status and education. Attitudes to calorie labelling were generally positive, but were less favourable among alcohol drinkers than non-drinkers. Hazardous drinkers were more accurate in their estimations of the calorie content of wine, cider and spirits than non-drinkers (p<0.0001). Overall, 46.4% of drinkers indicated that they would change their drinking patterns if calorie labelling was introduced, and this response was more common among hazardous than low-risk drinkers (OR=1.43, 95% CI 1.199 to 1.699), adjusting for age, gender, ethnicity, socioeconomic status and education. Compared with low-risk drinkers, hazardous drinkers stated that they would be more likely to drink fewer alcoholic beverages, to drink alcohol less often, to choose lower calorie drinks and to do more exercise (adjusted OR 1.27, 1.009 to 1.606). CONCLUSIONS: A sizeable proportion of hazardous drinkers indicated that they would change their consumption practices if mandatory calorie labelling was introduced. Promoting more positive attitudes to calorie labelling might lead to stronger intentions to reduce consumption. Mandatory calorie labelling of alcoholic beverages may make a modest contribution to energy intake and the maintenance of health weight, particularly among heavier drinkers.

Precision assessment of a hypertension prevalence survey.

BACKGROUND: Population surveys are crucial for public policy planning and provide valuable representative data. In the health sector studies to identify and assess the prevalence of Arterial Hypertension (AH), a chronic non-communicable disease (NCD), along with its associated risk factors have been conducted. OBJECTIVES: This study aims to assess the effectiveness of a population health survey in estimating the prevalence of arterial hypertension (AH) in the Sorocaba municipality between August 2021 and June 2023. METHODS: The analyzed performance indicator is the precision (design effect - deff) of AH prevalence in adults (≥ 18 years) and their exposure to primary risk factors. The total sample included 1,080 individuals from the urban area, deemed sufficient to estimate a deff of 1.5. This cluster-based study utilized census sectors as clusters, with data collected through household interviews, standardized questionnaires, and measurements of blood pressure and biometric parameters. The deff calculation formula used was weighted variance / raw variance. The Research Ethics Committee approved this study, with registration CAAE 30538520-1-0000-5373. RESULTS: The deff values ranged from 0.44 for chronic obstructive pulmonary disease to 1.63 for asthma, with a deff of 1.00 for AH prevalence. CONCLUSION: The study demonstrated good precision in its results, with high receptivity and cooperation from participants. The cost-effectiveness of the research deemed appropriate. The technique of selecting households within clusters (census sectors) based on detailed mapping and demographic data from the Instituto Brasileiro de Geografia e Estatística (IBGE) proved to be practical and efficient, suitable for replication in other municipalities and for studying other NCDs.

Self-perception of oral health, gender and employment among Brazilian population.

BACKGROUND: Self-perception of oral health is a recognized indicator, based on a single question. Association among oral health and socioeconomic status has been well established, however in Brazil, no results were found on the relation with type of insertion in labor market. OBJECTIVE: The aim of this study was to describe the prevalence of negative self-perception of oral health and associated factors, according to gender among Brazilian workers population, in 2019. METHODS: The National Health Survey, nationwide household-based survey, carried out in 2019, was used as source of data. Absolute and relative frequencies were calculated to understand the distribution of variables of interest and characterize the sample (n = 54,343). Binary logistic regression was used in the analyses. Odds ratio (OR) was estimated using a 95% confidence interval in bivariate and multivariate analyses. RESULTS: The prevalence of negative self-perception of oral health was 29.3%; in that, 31.0% among men and 27.2% among women. Compared to formal employees, the chance of negative self-perception of oral health among the informal workers was almost 20% higher among men and 13% among women after adjusting for all confounding factors. Unemployed women were 33% more likely to have negative self-perception of oral health. CONCLUSIONS: Self-reported unemployment increased the chance of a negative self-perception of oral health among women; however, the same effect was not observed among men. Why is there a difference? The association between informal work and negative SEOH is relevant in the Brazilian context of work deregulation and growth in the number of people without access to formal employment. The results suggested addressing employment conditions in adult oral health promotion actions, with emphasis on gender differences.

Lack of knowledge about the human papillomavirus vaccine among Brazilian adolescents: A cross-sectional study.

To analyze the distribution and factors associated with lack of knowledge about the human papillomavirus (HPV) vaccine among Brazilian adolescents.Cross-sectional study using the 2019 National School Health Survey among 17,805 Brazilian students of public and private schools, aged 13-17 years. The outcome variable was "lack of knowledge about the HPV vaccine" and the explanatory variables were sociodemographic, behaviors, knowledge, and health conditions. Logistic regression model was used to calculate Odds Ratio (OR) and 95% confidence intervals (95%CI). Spatial analysis techniques were used to determine the formation of clusters in the federated units with similar proportions of adolescents who were unaware of the vaccine. The lack of knowledge about the HPV vaccine was reported by 45.54% of Brazilian students. There was a higher chance of lack of knowledge having had sexual intercourse (OR 1.43; 95% CI 1.20-1.70); attending public school (OR 1.72; 95%CI 1.47-2.02) and located in the Northeast Region (OR 1.35; 95%CI 1.08-1.69). The lower chance of lack of knowledge were female gender (OR 0.41; 95% CI 0.35-0.48), higher maternal education (OR 0.62; 95% CI 0.50-0.77) self-rated health as Poor/very poor (OR 0.64; 95% CI 0.49-0.86) and receiving contraceptive counseling (OR 0.77; 95% CI 0.65-0.91). The proportion of lack of knowledge about the HPV vaccine was higher with the formation of High-High spatial clusters in the states of Maranhão, Piauí, and Pernambuco. Sociodemographic, health, and behavioral conditions and knowledge of students, as well as school characteristics, were associated with lack of knowledge about the HPV vaccine. A higher frequency of lack of knowledge about the HPV vaccine among adolescents was found in the states of the Northeastern Region.

Mukbang and Cookbang watching and dietary behavior in Korean adolescents.

BACKGROUND/OBJECTIVES: Given that adolescents watch Mukbang (eating broadcast) more frequently than other age groups, interest in the potential health effects of watching Mukbang and Cookbang (cooking broadcast) is growing. This study aimed to determine the status of watching Mukbang and Cookbang among Korean adolescents and its relationship with their dietary behaviors. SUBJECTS/METHODS: We used data from the 18th Korea Youth Risk Behavior Survey, conducted in 2022 (n = 51,850). The study included the frequency of watching Mukbang and Cookbang and the self-rated impact of watching them. Dietary behaviors included consumption of the following items: fruits (≥ once a day), vegetables (≥ 3 times a day), fast foods (≥ 3 times a week), late-night snacks (≥ 3 times a week), caffeinated drinks (≥ 3 times a week), and sweet-flavored drinks (≥ 3 times a week). Furthermore, obesity, weight loss attempts during the past 30 days, body image distortion, and inappropriate methods to control weight were also included. RESULTS: Among adolescents, 70.6% watched Mukbang and Cookbang, and 13.2% watched them more than 5 times a week. Approximately 27.6% of the adolescents responded that they were influenced by watching Mukbang and Cookbang. Adolescents who frequently watched Mukbang and Cookbang consumed less vegetable and fruit; however, the likelihood of consuming fast food, late-night snacks, sugary drinks, and caffeinated drinks increased. In addition, they were more likely to attempt inappropriate weight-loss methods and become obese. Adolescents who responded that their eating habits were influenced by watching Mukbang and Cookbang were more likely to have unhealthy eating behavior compared to the group who responded that their habits were not influenced by these shows. CONCLUSION: Watching Mukbang and Cookbang is common among Korean adolescents and is associated with unhealthy dietary behaviors. Prospective studies, including broadcasting content, should evaluate the impact of Mukbang and Cookbang on health.

Evaluation of the knowledge, attitude and practice towards ischaemic stroke among healthcare workers in neurology and neurosurgery department: a cross-sectional study in Shaanxi province, China.

OBJECTIVES: Healthcare workers play an important role in the timely recognition and treatment of patients who had an ischaemic stroke. However, their knowledge, attitude and practice (KAP) towards ischaemic stroke have not been well studied. This study aimed to assess the KAP towards ischaemic stroke among healthcare workers in the neurology and neurosurgery department in Shaanxi province, China. DESIGN: Cross-sectional study. SETTING: Medical centres in Shaanxi province. PARTICIPANTS: Healthcare workers in the neurology and neurosurgery department at Shaanxi province. PRIMARY AND SECONDARY OUTCOME MEASURES: Demographic characteristics and KAP towards ischaemic stroke were collected by a self-designed questionnaire. RESULTS: A total of 259 (96.6%) valid questionnaires were collected. Their mean KAP scores were 19.56±3.72 (total score: 23), 36.56±3.56 (total score: 40) and 27.45±3.00 (total score: 30), respectively. Multivariate logistic regression analysis demonstrated that education (bachelor's degree or above vs college or below: OR=2.704 (1.286-5.685), p=0.009), gender (female vs male: OR=0.401 (0.227-0.710), p=0.002) and professional title (intermediate vs no title: OR=0.280 (0.107-0.731), p=0.009) were independently associated with good knowledge; knowledge score (OR=1.266 (1.157-1.387), p<0.001) and hospital (private hospital vs public hospital: OR=0.544 (0.313-0.944), p=0.030) were independently associated with good attitude; and attitude score (OR=1.480 (1.326-1.652), p<0.001), gender (female vs male: OR=0.511 (0.264-0.993), p=0.047) and occupation (other healthcare workers vs physicians: OR=0.252 (0.129-0.495), p<0.001) were independently associated with good practice. CONCLUSION: The healthcare workers in the neurology and neurosurgery department demonstrated a satisfactory KAP towards ischaemic stroke. Targeted and tailored training programmes might be an optional way to improve their practice.

Spatial analysis and factors associated with low birth weight in Ghana using data from the 2017 Ghana Maternal Health Survey: spatial and multilevel analysis.

OBJECTIVE: Low birth weight (LBW) is an important indicator of newborn health and can have long-term implications for a child's development. Spatial exploratory analysis provides a toolkit to gain insight into inequalities in LBW. Few studies in Ghana have explored the spatial distribution of LBW to understand the extent of the problem geographically. This study explores individual and cluster-level distributions of LBW using spatial exploration components for common determinants from nationally representative survey data. DESIGN: We used data from the 2017 Ghana Maternal Health Survey and conducted individual-level and cluster-level analyses of LBW with place and zone of residence in both bivariate and multivariate analyses. By incorporating spatial and survey designs methodology, logistic and Poisson regression models were used to model LBW. SETTING: Ghana. PARTICIPANTS: A total of 4127 women aged between 15 and 49 years were included in the individual-level analysis and 864 clusters corresponding to birth weight. PRIMARY AND SECONDARY OUTCOME MEASURES: Individual and cluster-level distribution for LBW using spatial components for common determinants. RESULTS: In the individual-level analysis, place and zone of residence were significantly associated with LBW in the bivariate model but not in a multivariate model. Hotspot analysis indicated the presence of LBW clusters in the middle and northern zones of Ghana. Compared with rural areas, clusters in urban areas had significantly lower LBW (p=0.017). Clusters in the northern zone were significantly associated with higher LBW (p=0.018) compared with the coastal zones. CONCLUSION: Our findings from choropleth hotspot maps suggest LBW clusters in Ghana's northern and middle zones. Disparities between the rural and urban continuum require specific attention to bridge the healthcare system gap for Ghana's northern and middle zones.

Complete Loss of Natural Teeth and Loneliness: A Fixed-Effect Analysis.

Psychosocial properties of oral health have been reported. The present study aimed to investigate the causal effect of complete loss of natural teeth on loneliness by using fixed-effects analysis to control for confounding factors, including unmeasured time-invariant factors. Data from older adults participating in at least 2 consecutive waves of the English Longitudinal Study of Ageing in waves 3 (2006/2007), 5 (2010/2011), and 7 (2014/2015) were analyzed (N = 18,682 observations from 7,298 individuals). The association between complete loss of natural teeth and loneliness score (ranging from 3 to 9) was examined using fixed-effect linear regression analysis adjusting for time-varying confounders, including sociodemographic and health characteristics. The prevalence of complete tooth loss was 12.7%, 12.8%, and 10.6% in waves 3, 5, and 7, respectively. Individuals who transitioned to complete tooth loss during any 2 consecutive waves had an increase in loneliness score by 0.27 (95% confidence interval [CI] 0.03, 0.52), which was greater than those who maintained natural teeth (-0.03; 95% CI -0.05, -0.01). Fixed-effects analysis adjusting for time-varying confounders revealed a significant association between complete loss of natural teeth and an increase in loneliness score by 0.31 (95% CI 0.17, 0.46). Complete loss of natural teeth among older adults in England was associated with loneliness, even after accounting for measured time-varying and (un)measured time-invariant confounders. Retaining natural teeth may reduce the risk of loneliness.

Changes in Daily life due to the COVID-19 Pandemic and Mental Health Status in Korean Adolescents.

This study assessed the relationship between daily life changes and mental health in Korean adolescents during the COVID-19 pandemic. Data from middle and high school students who responded to the relevant survey items the 2021 Korea Youth Risk Behavior Survey were analyzed (n = 53,868). The survey assessed changes in economic status, physical activity, skipping breakfast, drinking, smoking, and mental health, including stress, depression, generalized anxiety disorder, and suicidal ideation, due to the COVID-19 pandemic. The overall prevalence of perceived stress, depression, generalized anxiety disorder, and suicidal ideation was 38.6%, 26.4%, 12.2%, and 12.4%. Adolescents whose economic status worsened due to COVID-19 had a higher risk of perceived stress, depression, generalized anxiety disorder, and suicidal ideation. Changes in physical activity and breakfast consumption due to the COVID-19 pandemic were significantly associated with increases in perceived stress, depression, generalized anxiety disorder, and suicidal ideation. Adolescents who increased their alcohol consumption had the highest risk of perceived stress, depression, generalized anxiety disorder, and suicidal ideation. Changes in economic status and health behaviors caused by the COVID-19 pandemic had a negative effect on the mental health of Korean adolescents. These results can be used to identify adolescents at high risk of developing mental health problems.

Improving Identification of Gig Workers in National Health and Behavior Surveys.

This paper describes the work-related information collected in several important U.S. national health and behavior surveys, to highlight data gaps that prevent identifying responses by vulnerable workers in the gig economy, with emphasis on the growing digital platform sector of the work force. The national information systems used to understand health status and health behaviors, including drug use, rely on outdated census categories for self-employed workers. This paper describes the importance of understanding the needs of this growing part of the labor sector and describes how some of the most well-known and utilized national surveys fail to meet this need. For the agencies conducting national health and behavior surveys, we propose revisions to the categories used to classify type of worker and recommend adoption of a new Worker-Employer Relationship Classification model.
