Public opinion on COVID-19 pandemic in Bangladesh: Disruption to public lives and trust in government's immunisation performance.

OBJECTIVES: The COVID-19 pandemic has stretched Bangladesh government's capability for disaster engagement. As normalcy is interrupted, people's confidence in the government in ending the crisis needs evaluation, especially considering the past vaccination successes in Bangladesh and growing worldwide vaccine hesitancy amidst the COVID-19 misinfodemic. This study assessed the level of public life disruption due to the pandemic at the micro-level and how much impact it had on people's trust in the government's capacity for successful national immunisation. METHODS: Given the infectious nature of the pandemic, the study conducted an online survey of 2291 respondents, distributed proportionally across sex and income groups. We conducted bivariate analyses and fitted generalised linear models to assess disruption to respondents' lives, and their trust in the government's immunisation ability, which were measured using multiple parameters. RESULTS: Nearly 50% of the respondents reported multifaceted disputations in their daily lives, with 90% suffering financially. Trust in the government was very low at the time of the survey as only 11.3% of respondents had faith that the government could successfully conduct a mass vaccination campaign. Rural residents and non-earning members of families found their lives to be less disrupted. Comparatively higher income families and highly educated individuals had lesser confidence in the government's inoculation capabilities. CONCLUSIONS: For the vaccine campaign to be successful, effective risk communication and timely display of data-driven decision-making efforts targeting the groups who are more sceptical of immunisation campaigns could be of significance to the Bangladesh government.

Women's decision-making power can influence modern contraceptive use: Evidence from Bangladesh.

OBJECTIVES: It is generally believed that gender inequality and women's lack of decision-making power may restrict women's use of modern contraception, leading to high rates of unwanted pregnancies, abortions, and deaths. Evidence shows that empowered women are more likely to use modern contraception methods, but few studies have investigated this across multiple domains of empowerment. STUDY DESIGN: This study examined the associations between women's empowerment and modern contraception use in Bangladesh. Data from a sample of 16,834 married women aged 15-49 years from the Bangladesh Demographic and Health Survey 2017-2018 were analysed. METHODS: Complex survey weight adjusted logistic models were fitted to evaluate the associations after adjusting for clusters, strata, and sampling weights. RESULTS: indicate that just over half of the married women (55.7%) had used modern contraception methods. Women's empowerment was associated with contraceptive use, especially decision-making power. Women who had medium or high autonomy of household decision making were likely to have 20% (AOR = 1.20; 95% CI: 1.04-1.39) and 27% (AOR = 1.27, 95% CI: 1.11-1.45) increased odds of using modern contraceptives compared to those who scored low in the decision-making domain. The findings demonstrated strong evidence of direct influence of women's decision-making power on modern contraception use. The results also found influence of several socio-demographic factors including area of residence, husband's age, wealth index and mobile phone ownership on the use of modern contraceptives. DISCUSSION: Future interventions can focus on integrating women's empowerment into family planning programming, with a particular focus on enhancing women's autonomy in decision making.

Contraceptive use in South and South-East Asian region: assessment of sustainable development goal 3.7 through indicator 3.7.1.

BACKGROUND: Sustainable Development Goal (SDG) 3.7 concerns modern contraception use among women of reproductive ages. This study evaluated the progress of indicator 3.7.1 in 11 selected countries in South and South-East Asia and assessed the contribution of women's education to modern contraceptive use. METHODS: Generalized linear models for complex surveys were fitted to Demographic and Health Survey (DHS) data from 40 surveys conducted in Afghanistan, Bangladesh, Cambodia, India, Indonesia, Maldives, Myanmar, Nepal, Pakistan, Philippines and Timor Leste between 1990 and 2017, followed by a meta-analysis through forest plots. RESULTS: Modern contraceptive coverage in most of the selected countries climbed or remained stationary over the past decades. In four countries, <50% of women used contraception. In no country was contraception used by ≥80% women. Higher education was associated with 13% higher odds of modern contraceptive use (95% confidence interval: 1.07, 1.18) among women compared to primary level or no education. DISCUSSION: Completion of primary education is insufficient to broaden the coverage of modern contraceptive use. Greater national level effort from the selected countries is needed to lift the education levels of women to meet SDG 3.7 by 2030.

Residential area greenness and hypertension: a national assessment on urban adults in Bangladesh.

This study investigated the associations between greenness and blood pressure (BP) metrics (systolic BP [SBP], diastolic BP [DBP], hypertension) among urban adults in Bangladesh and the potential mediation effects of body mass index (BMI) using 2011 Bangladesh Demographic and Health Survey data for 2360 urban adults (aged ≥35 years). The Enhanced Vegetation Index was used as a measure of residential area greenness. Associations between greenness and BP metrics were estimated using linear and binary logistic regression models. We also conducted mediation analyses. Greater area-level greenness was inversely associated with SBP (ß -1.33, 95%CI: -2.46, -.20), DBP (ß -.83, 95%CI: -1.64, -.02), and hypertension (adjusted odds ratio .87, 95%CI: .77, .98). BMI substantially mediated associations between greenness and BP metrics. Adopting urban greening policies could reduce the risk of hypertension, thus can contribute to reduction of non-communicable disease burden in Bangladesh. Longitudinal studies are required to further investigate the causal pathways.

Relationship between blood pressure and BMI in young adult population: a national-level assessment in Bangladesh.

Young adulthood is a crucial period for major physiological transitions. Environmental changes associated with these transitions can influence health behaviour and health (e.g. poor diet, high body weight and elevated blood pressure (EBP)). Excess body weight can lead to EBP; however, little is known about this relationship among young adults in developing countries. Focusing on Bangladesh, this study assessed the association between BMI and blood pressure (BP) metrics (systolic BP (SBP), diastolic BP (DBP) and BP class (optimal, normal/high normal and elevated)). Sex-specific analyses of these relationships were performed to assess any difference across sexes. Furthermore, associations of overweight/obesity with BP metrics were investigated. Young adults aged 18-24 years (n 2181) were included from nationally representative cross-sectional Bangladesh Demographic and Health Survey 2017-2018. Multivariable linear and multinomial logistic regression models examined the relationships between BMI, overweight/obesity and BP metrics. Findings reveal that higher BMI was associated with higher SBP (0·83; 95 % CI 0·67, 0·99), DBP (0·66; 95 % CI 0·54, 0·74) and higher odds of having EBP (adjusted OR 1·24; 95 % CI 1·17, 1·31). These relationships were stronger among males than females. Moreover, overweight/obese individuals had higher SBP, DBP and higher odds of having EBP than individuals with normal BMI. Strategies to reduce body weight and to improve healthy lifestyle, and awareness and monitoring of BP may help to address these serious health problems, particularly at an early age.

Body mass index of women in Bangladesh: comparing Multiple Linear Regression and Quantile Regression.

This study explored the association between socio-demographic factors and the body mass index (BMI) of women of reproductive age (15-49 years) in Bangladesh. Data from the 2014 Bangladesh Demographic and Health Survey (BDHS-14) were analysed using Multiple Linear Regression (MLR) and Quantile Regression (QR) analyses. The study sample comprised 15,636 non-pregnant women aged 15-49. The mean BMI of the women was 22.35±4.12 kg/m2. Over half (56.75%) had a BMI in the normal range (18

Underreporting COVID-19: the curious case of the Indian subcontinent.

COVID-19 has spread across the globe with higher burden placed in Europe and North America. However, the rate of transmission has recently picked up in low- and middle-income countries, particularly in the Indian subcontinent. There is a severe underreporting bias in the existing data available from these countries mostly due to the limitation of resources and accessibility. Most studies comparing cross-country cases or fatalities could fail to account for this systematic bias and reach erroneous conclusions. This paper provides several recommendations on how to effectively tackle these issues regarding data quality, test coverage and case counts.

Prevalence of stress, anxiety and depression due to examination in Bangladeshi youths: A pilot study.

An estimated 25% people suffer from mental health disorders worldwide. Almost 7 million suffer from anxiety and depression in Bangladesh. There are several factors that can cause stress among youths, both academic and non-academic, ranging from socioeconomic, environmental, cultural and psychological attributes. However, these are not widely researched in Bangladesh. This study identified the factors that affect the mental health of students due to examinations in Bangladesh, particularly the socio-demographic, lifestyle and psychological factors. An online cross-sectional survey was conducted on May 2020 with a sample size of 210 tertiary level students in Dhaka. A modified DASS-21 was used to measure stress, anxiety and depression scores related to examination. Binary logistic model showed that those who lived with family, spent time with parents, had regular sufficient (self-assessed) sleeps and consumed balanced (self-assessed) diets had significantly lower stress, anxiety, and depression. Balanced lifestyle with greater social bonding might help to better equip youths to reduce stress, anxiety, and depression during examination, which could be an avenue for future intervention studies.

Factors associated with the availability of iodized salt at household level: a case study in Bangladesh.

OBJECTIVE: The availability of iodized salt in households remains low in Bangladesh, which calls for improving the salt iodization quality and its coverage. The present study assessed the socio-economic disparity in Bangladesh to characterize the availability of iodized salt at household level. DESIGN: Associations between different socio-economic factors and availability of iodized salt at household level were explored using Bayesian mixed-effects logistic models after adjusting the district- and cluster-level random effects. SETTING: Bangladesh Multiple Indicator Cluster Survey (MICS), 2012-13.ParticipantsHouseholds (sample size, n 50981). RESULTS: Results showed that 73·15 % of household salt samples were iodized to some extent although iodization level varied. According to the regression model, houses with young (adjusted odds ratio of posterior mean (OR) = 1·31; 95 % credible interval (CI) 1·09, 1·64) and educated (OR = 3·66; 95 % CI 3·25, 4·23) household heads had significantly higher likelihood of availability of iodized salt. In addition, iodized salt was less likely be found in poor and rural households, as urban households were 2·88 times (95 % CI 2·41, 3·34) more likely have iodized salt. Moreover, the regional locations of the households were an important component that contributed to the local iodized salt coverage. As per the district-wise distribution, the north-west part of Bangladesh and Cox's Bazar in the far south seemed to lack household-level iodized salt. CONCLUSIONS: Our findings suggest that iodized salt intervention should be promoted considering the area variations, which could potentially help policy makers to design interventions in the context of Bangladesh.

Double burden of underweight and overweight among women of reproductive age in Bangladesh.

OBJECTIVE: Bangladesh, like many emerging economies of South-East Asia, has started to experience a double burden of continuing high rates of undernutrition and increasing rates of overweight and obesity. A lack of assessment of the nutritional shift leaves a gap in current policies: the growing overweight and obesity is yet to be addressed. The present paper investigates the change in nutritional status, particularly the shift in BMI, of Bangladeshi women of reproductive age (15-49 years) and characterizes the vulnerable households for both underweight and overweight status during a period of 10 years (2004-2014). DESIGN: Generalized linear mixed-effect models were fitted for both urban and rural residents to assess underweight and overweight status. SETTING: Bangladesh Demographic and Health Surveys. PARTICIPANTS: Women aged 15-49 years (n 53 077). RESULTS: The proportion of overweight increased during 2004-2014 from 10·7 to 25·1 % and the proportion of underweight decreased from 32·6 to 18·2 %. Prevalence of underweight status remained high in rural areas and prevalence of overweight increased rapidly in both rural and urban areas, creating a double burden. The significant contributors to this double burden were the change in women's level of education, increased household wealth, divisional location and rapid urbanization. CONCLUSIONS: The findings indicate that specific cohort- or area-based intervention policy studies in line with the UN Decade of Action on Nutrition are required to address the nutritional double burden in Bangladesh.

Women's Attitudes Toward Intimate Partner Violence in Low- and Middle-Income Countries of Southern Asia.

PURPOSE: The present study identified the vulnerable IPV cohorts of South Asian women, and the prevalence of and predictors of the women's IPV acceptance. DESIGN: Cross-sectional survey - the United Nations Children's Fund multiple index cluster survey. SETTING: Many South Asian women are accepting of IPV. Studies mostly focus on individual countries. SUBJECT: 103 139 ever-married women from Bangladesh, Laos and Nepal. MEASURES: Women's attitudes toward IPV were measured using a set of five, fixed, binary responses. ANALYSIS: Following bivariate analysis, complex survey weight adjusted logistic regression models were fitted for individual country data, and the pooled sample. RESULTS: Of the sampled South Asian women 27.8% accepted IPV, and no major variation among countries in IPV acceptance. Education was the most reliable protector against IPV acceptance whereby, higher educational attainment systematically reduced IPV acceptance (OR = .61 [.56-.83]). Other significant protective factors were being un-married (Married OR = 1.34 [1.28-1.42]), having increased wealth (OR = .71 [.56-.83]), and being over 24 years old (OR = .88 [.83-.97]). CONCLUSION: Only education produced absolute consistency at the country and region level; there seems to be no blanket solution for regionally reducing women's IPV acceptance rates in Southern Asia. Focus on the least educated women and making education more accessible should be prioritised. Future IPV studies can consider measurement methods for women's direct exposure to patriarchal standards and within community interaction.

Hypertension, diabetes, and hypercholesterolemia in Bangladesh: Evaluating role of physical activity from cross-sectional STEPS 2018 survey.

Background and Aims: The objective of this study was to assess current condition of three noncommunicable diseases (NCDs)-diabetes, hypertension, and hypercholesterolemia and vulnerable cohorts among adults in Bangladesh. Methods: The STEPwise Approach to the NCD Risk Factor Surveillance survey of 2018 was analyzed to evaluate the association between NCDs and sociodemographic factors, levels of physical activity, and behavioral measurements. Complex survey weight-adjusted logistic models were fitted. Results: From 6875 samples, prevalence of diabetes, hypertension and hypercholesterolemia were 27.3%, 9.8%, and 30.2%, respectively. The prevalence of the three NCDs were higher among older respondents. Low occupational activity with obese-BMI status people was more prone to NCDs. Lower prevalence of hypercholesterolemia was observed in Rangpur, Rajshahi, and Mymensingh, whereas lesser diabetes in Khulna region. Likelihood of NCDs were higher among highly educated, urban residents with low physical activity. Lesser physical activity, and lack of weight maintenance were found to be key factors in higher rates of NCDs in Bangladesh. Conclusion: Greater education and less strenuous profession led to a higher chance of NCDs. Overall, physical activity and maintenance of weight seem to be factors driving higher rates of NCDs in Bangladesh. As a preventive measure against NCDs, an active lifestyle is to be encouraged, particularly to the most vulnerable cohort.

Antenatal Care Visits, Institutional Births, and Associated Risk Factors in Afghanistan: Insights from the Multiple Indicator Cluster Survey 2022-2023.

INTRODUCTION: Insufficient use of antenatal care (ANC) services and institutional births services can elevate the maternal mortality risk in limited resource settings. Hence, the key objective of this study was to evaluate the potential association between the frequency of ANC visits and institutional birth services in Afghanistan, while also identifying other sociodemographic factors that may exert influence. Furthermore, we explored factors associated with the attendance of women at ANC visits during their pregnancy. METHODS: We employed data from the most recent Multiple Indicator Cluster Survey conducted in Afghanistan in 2022 to 2023 with a total of 8096 women aged 15 to 49. A complex survey weight-adjusted logistic regression model was used to examine factors related to institutional births, and a multinomial logistic regression model was fitted to assess the relationships between sociodemographic factors and ANC visits, adjusting for survey weights, cluster effects, and strata. RESULTS: Approximately 40% of the sample (n = 3247) had undergone 4 or more ANC visits, and 74.4% (n = 6,022) had opted for institutional birth. Women's higher education was found to be associated with ANC visits. The area of residence, wealth index, education levels of women, ownership of mobile phones, number of children, and number of ANC visits were associated with institutional births. Compared with women with no or one ANC visit, those with more than 3 visits had 31% higher odds (adjusted odds ratio, 1.31; 95% CI, 1.10-1.57) of accessing institutional births. DISCUSSION: Our findings indicate a significant association between ANC visits and use of institutional birth care. These findings carry implications for advancing safe motherhood and childbirth by enhancing women's social status.

Addictive behavior and mental health of adolescents aged 11-17 years in Bangladesh in 2014: A cross-sectional study.

Background and Aims: This study aimed to evaluate the factors associated with addictive behavior and mental health in adolescents aged 11-17 years in Bangladesh. Methods: This study analyzed data from the Bangladesh Global School-based Health Survey (GSHS) conducted in 2014. Adolescents aged 11-17 years studying government schools were considered as respondents for this survey. A two-phase group sample design was utilized to deliver illustrative information of all understudies in grades (classes) 7-10 in Bangladesh. Bivariate analyses followed by a weight-adjusted multiple logistic regression was fitted to a sample of size 2989 adolescents. Results: One in ten and one in four adolescents had different substance addictions and some forms of mental health conditions, respectively. Sex of participants (adjusted odds ratio [AOR]: 4.49; confidence interval [CI]:2.28-8.84), being bullied (AOR: 3.08; CI:1.46-6.49), use of tobacco among parents (AOR: 5.82; CI:3.16-10.75), parental understanding of adolescents' problems (AOR: 0.45; CI:0.23-0.82), and food affordability (AOR: 1.24; CI:1.09-1.42) were associated with addictive behaviors of adolescents. Bullied males with nonempathetic parents were found to be more vulnerable to addictive behaviors and bullied females showed higher tendencies to mental health issues. Conclusion: Considering the elevated prevalence of reported mental health concerns, identifying vulnerable groups and formulating intervention-oriented policies engaging youths can pave the way towards achieving robust health and well-being for them in Bangladesh.

Device-Measured Weekend Catch-Up Sleep, Mortality, and Cardiovascular Disease Incidence in Adults.

STUDY OBJECTIVE: Attempting to recover a sleep debt by extending sleep over the weekend is a common compensatory behavior in the population and is recommended by sleep-focused organizations. However, the purported benefits of catch-up sleep are based on a limited number of cross-sectional studies that relied on self-reported sleep. The objective of this study was to examine the association between accelerometer-derived weekend catch-up sleep and mortality and incident cardiovascular disease (CVD) in adults. METHODS: A prospective cohort study of UK adults who wore wrist-attached accelerometers was conducted. Weekend catch-up sleep was defined as a longer average sleep duration on weekends compared to weekdays. Participants were categorized into four groups: no weekend catch-up sleep (reference); >0 to <1 hour; ≥1 to <2 hours; and ≥2 hours difference. Associations between weekend catch-up sleep and mortality and incident CVD were assessed using Cox proportional hazards regression, adjusted for potential confounders. RESULTS: A total of 73,513 participants (sample for mortality) and 70,518 participants (sample for CVD incidence) were included, with an average (SD) follow-up period of 8.0 (0.9) years. In multivariable-adjusted models, weekend catch-up sleep was not associated with mortality (≥2 hours group: hazard ratio [HR], 1.17 [95% CI, 0.97-1.41]) or incident CVD (HR, 1.05 [95% CI, 0.94-1.18]). Dose-response analyses treating catch-up sleep as a continuous measure or analyses restricted to adults sleeping less than 6 hours on weekdays at baseline were in agreement with these findings. CONCLUSION: Weekend catch-up sleep was not associated with mortality or CVD incidence. These findings do not align with previous evidence and recommendations by sleep authorities suggesting that extending sleep over the weekend may offer protective health benefits.

Joint Associations of Diet and Device-Measured Physical Activity with Mortality and Incident CVD and Cancer: A Prospective Analysis of the UK Biobank Study.

BACKGROUND: We examined the joint associations of diet and device-measured intensity-specific physical activity (PA) with all-cause mortality (ACM), cardiovascular disease (CVD), and cancer incidence. METHODS: We used data from 79,988 participants from the UK Biobank, a population-based prospective cohort study. Light PA (LPA), moderate-to-vigorous PA (MVPA), vigorous PA (VPA), and total PA (TPA) were measured using a wrist-worn accelerometer. Diet quality score (DQS) was based on 10 foods and ranged from 0 (unhealthiest) to 100 (healthiest) points. We derived joint PA and diet variables. Outcomes were ACM, CVD, and cancer incidence including PA, diet and adiposity-related (PDAR) cancer. RESULTS: During a median follow-up of 8 years, 2,863 deaths occurred, 11,053 participants developed CVD, 7,005 developed cancer, and 3,400 developed PDAR cancer. Compared with the least favorable referent group (bottom PA tertile/low DQS), participants with middle and high (total and intensity specific) PA, except for LPA, had lower ACM risk and incident CVD risk, regardless of DQS. For example, among middle and high VPA and high DQS groups, CVD HR were 0.79 (95% CI, 0.74-0.86) and 0.75 (95% CI, 0.69-0.82), respectively. The pattern of cancer results was less pronounced but in agreement with the ACM and CVD incidence findings (e.g., HR, 0.90, 95% CI, 0.81-0.99; 0.88, 0.79-0.98; and 0.82, 0.74-0.92 among high VPA for low, moderate, and high DQS groups, respectively). CONCLUSIONS: Device-measured PA reveals novel joint associations with diet on health outcomes. IMPACT: Our results emphasize the crucial role of PA in addition to a healthy diet for reducing chronic diseases and mortality risk.

Modification of incident cancer risk with changes in metabolic syndrome status: A prospective cohort study in Taiwan.

PURPOSE: We aimed to investigate the effect of altered metabolic syndrome (MetS) status on cancer risk. METHODS: From 2002 through 2008 of the Taiwan MJ cohort, there were 111,616 adults who had repeated MetS measurements performed 3.3 years apart and were followed up for cancer incidence over 11.8 years. Cancer was confirmed based on histopathological reports. RESULTS: Participants were categorized as MetS-free (n = 80,409; no MetS at the first or last health screening), MetS-developed (n = 9833; MetS absence at the first screening and presence at the last screening), MetS-recovered (n = 8958; MetS presence at the first screening and absence at the last screening), and MetS-persisted (n = 12,416; MetS presence at the first and last screenings). We used the Fine-Gray sub-distribution method, with death as competing risk, to determine the association between MetS changes and incident cancer risk. During 1320,796 person-years of follow-up, 5862 individuals developed cancer. The incidence rate of cancer per 1000 person-years was 3.89 in the MetS-free, 5.26 in MetS-developed, 4.61 in MetS-recovered, and 7.33 in MetS-persisted groups (P < .001). Compared with the MetS-free group, MetS-persisted individuals had a higher risk of incident cancer. CONCLUSIONS: Persistent MetS was found to be associated with a high risk of incident cancer.

Investigating factors affecting HIV/AIDS knowledge among women in low and middle-income countries in Asia.

Sustainable Development Goal 3 focuses on reducing HIV/AIDS spread, for which disseminating correct information on the disease is required. This study investigated factors associated with HIV/AIDS knowledge among women in several Asian LMICs. Global Multiple Indicator Cluster Survey-6 (MICS-6) for Bangladesh, Lao, Mongolia and Nepal were assessed. Bivariate analysis and generalised linear regression models were fitted. Overall, 60% of the respondents were aware or heard of the existence of HIV/AIDS, with 63.2% having transmission knowledge and 80.4% misconception knowledge. Results revealed that several demographic factors such as wealth index, education and access to information had a significant association with HIV/AIDS knowledge. Mongolia and Nepal have formal programmes in place that may provide policy and implementation advantages compared to Bangladesh and Lao.

Public opinion on COVID-19 vaccine prioritization in Bangladesh: Who gets the vaccine and whom do you leave out?

One of the most challenging aspects of the COVID-19 pandemic is the inability to ensure equitable distribution of vaccines to fight the pandemic. Many governments around the globe had to prioritize and perform a triage in distributing the vaccines due to the limited supply as well as a lack of financial strength to acquire a sufficient number of vaccines in time. The present study assessed the public opinion in Bangladesh regarding vaccination prioritization strategy and its associated aspects. Due to the infectious nature of the viral transmission, the study used an online survey and collected a sample of 2291 respondents, distributed proportionally across sex, and income groups. Descriptive statistics and multinomial logistic regression modelling were utilized to conduct the analyses. The results emphasized unanimous preference of prioritized vaccination leaning towards the frontline workers, the severely sick and the elderly. However, the segregation across ethnicity was noted with no major preference among sexes or religion. The results reinforce the Bangladesh government's undertaken strategy of prioritization. However, the preference rankings varied across sociodemographic factors including self-assessed COVID-19 knowledge and income tiers, among others. The findings underline the necessity of improved risk communication strategies to ensure public confidence and conformity to vaccination efforts and their effective deployment across the country.

Magnitude, variability and symmetry in head acceleration and jerk and their relationship to cervical and ocular vestibular evoked myogenic potentials.

BACKGROUND: Acceleration and changes in acceleration (jerk) stimulate vestibular otolith afferents. Bone-conducted (BC) vibration applied to the skull accelerates the head and produces short latency reflexes termed vestibular evoked myogenic potentials (VEMPs). OBJECTIVE: To determine the magnitude, variability and symmetry in head acceleration/jerk during VEMP recordings and investigate the relationship between head acceleration/jerk and VEMP properties. METHODS: 3D head accelerometery (sagittal, interaural and vertical axes) was recorded bilaterally in thirty-two healthy subjects during cervical (cVEMP) and ocular (oVEMP) recordings. BC 500 Hz sinusoidal tones were applied to the midline forehead using a positive polarity stimulus. RESULTS: The direction of induced acceleration/jerk was predominately backward, outward and downward on either side of the head during cVEMP and oVEMP recordings.Overall, acceleration/jerk was larger in the sagittal and interaural axes and peaked earlier in the interaural axis bilaterally. Acceleration was more symmetric in the sagittal and interaural axes whereas jerk symmetry did not differ between axes. Regression models did not show a systematic relationship between acceleration/jerk and either VEMP reflex. CONCLUSIONS: The pattern of skull acceleration/jerk was relatively consistent between the two sides of the head and across subjects, but there were differences in magnitude, leading to inter-side and inter-subject variability.
