Protecting against researcher bias in secondary data analysis: challenges and potential solutions

Analysis of secondary data sources (such as cohort studies, survey data, and administrative records) has the potential to provide answers to science and society’s most pressing questions. However, researcher biases can lead to questionable research practices in secondary data analysis, which can distort the evidence base. While pre-registration can help to protect against researcher biases, it presents challenges for secondary data analysis. In this article, we describe these challenges and propose novel solutions and alternative approaches. Proposed solutions include approaches to (1) address bias linked to prior knowledge of the data, (2) enable pre-registration of non-hypothesis-driven research, (3) help ensure that pre-registered analyses will be appropriate for the data, and (4) address difficulties arising from reduced analytic flexibility in pre-registration. For each solution, we provide guidance on implementation for researchers and data guardians. The adoption of these practices can help to protect against researcher bias in secondary data analysis, to improve the robustness of research based on existing data.

Assessing geographical and economic inequalities in caesarean section rates between the districts of Bihar, India: a secondary analysis of the National Family Health Survey

BackgroundIn Bihar, one of the most populous and poorest states in India, caesarean sections have increased over the last decade. However, an aggregated caesarean section rate at the state level may conceal inequities at the district level.ObjectivesThe primary aim of this study was to analyse the inequalities in the geographical and socioeconomic distribution of caesarean sections between the districts of Bihar. The secondary aim was to compare the contribution of free-for-service government-funded public facilities and fee-for-service private facilities to the caesarean section rate.SettingBihar, with a population in the 2011 census of approximately 104 million people, has a low GDP per capita (US$610), compared with other Indian states. The state has the highest crude birth rate (26.1 per 1000 population) in India, with one baby born every two seconds. Bihar is divided into 38 administrative districts, 101 subdivisions and 534 blocks. Each district has a district (Sadar) hospital, and six districts also have one or more medical college hospitals.MethodsThis retrospective secondary data analysis was based on open-source national datasets from the 2015 and 2019 National Family Health Surveys, with respective sample sizes of 45 812 and 42 843 women aged 15–49 years.ParticipantsSecondary data analysis of pregnant women delivering in public and private institutions.ResultsThe caesarean section rate increased from 6.2% in 2015 to 9.7% in 2019 in Bihar. Districts with a lower proportion of poor population had higher caesarean section rates (R2=0.45) among all institutional births, with 10.3% in private and 2.9% in public facilities. Access to private caesarean sections decreased (R2=0.46) for districts with poorer populations.ConclusionMarked inequalities exist in access to caesarean sections. The public sector needs to be strengthened to improve access to obstetric services for those who need it most.

Alcohol-related family violence in Australia: Secondary data analysis of the National Drug Strategy Household Survey

Aims: Alcohol is a risk factor for family violence that affects partners, parents, children and other relatives. This study aims to provide estimates of the prevalence of alcohol-related family violence reported in 2016 in Australia across numerous socio-demographic groups. Methods: This paper presents secondary data analysis of 23,749 respondents (10,840 men, 12,909 women) from the Australian Institute of Health and Welfare’s 2016 National Drug Strategy Household Survey (NDSHS). Alcohol-related family violence was measured by self-report as being physically or verbally abused or put in fear from a family member or partner deemed by the victim as under the influence of alcohol. Logistic regression was used to analyse which factors were associated with alcohol-related family violence. Findings: Analysis revealed that 5.9% of respondents (7.7% of women and 4.0% of men) reported alcohol-related family violence in the past year from either a partner or another family member. Respondents who were women (vs men), within less advantaged (vs more advantaged) socio-economic groups, risky drinkers (vs non-risky drinkers), residing in outer regional areas (vs major cities), holding a diploma (vs high school education) and single with dependents, reported higher overall rates of alcohol-related family violence. In contrast, respondents aged 55+ had significantly lower odds of experiencing alcohol-related family violence than all other age groups. Conclusions: Alcohol-related family violence was significantly more prevalent amongst respondents in a range of socio-demographic categories. Identification of these groups which are adversely affected by the drinking of family and partners can aid in informing current policy to protect those more vulnerable.

THE COVID-19 PANDEMIC: AN ACCELERATOR OF DIGITALISATION IN TOURISM

The aim of this paper is to analyse the effects of the COVID-19 pandemic on leveraging technology to generate new opportunities for travel companies. Tourism is one of the sectors most affected by the Covid-19 pandemic, companies in this sector have never faced such a dramatic situation and their challenge has been to survive and find new ways to generate profit. In this context, the pandemic has become an accelerator of digitalisation and has made digital technologies vital. The study is based on secondary data analysis and the research objectives are to examine the impact of COVID - 19 on travel companies and to highlight the importance of developing digitalisation during the pandemic. To achieve these goals, the authors analysed the actions during the pandemic of the world's largest tour operator, Tui Group

Factors Associated with the 4-Year Estimated Incidence of Type 2 Diabetes Mellitus by Sex in Korean Adults: Secondary Data Analysis

It is important to prevent the increase in the prevalence of diabetes mellitus (DM) worldwide by efficiently managing its controllable risk factors. This study aimed to identify factors associated with the 4-year estimated incidence of type 2 DM (T2DM) by sex and provide basic data for a sex-specific strategic approach to lifestyle modification. We performed a secondary data analysis using raw data from the seventh Korea National Health and Nutrition Examination Survey (KNHANES, 2016–2018). The KNHANES is a descriptive correlational survey designed to examine sex differences in the factors associated with the 4-year estimated incidence of T2DM. This study included 9,614 Korean adults (4,134 men and 5,480 women) aged 40–69 years without a diagnosis of T2DM. For the statistical analysis, a complex sample analysis was performed for sex comparison using the χ2-test or one-way analysis of variance; a multiple regression analysis was performed to analyze the sex-specific influencing variables of 4-year estimated T2DM incidence. The waist-to-height ratio, an indicator of central obesity in adults, showed the strongest association with the 4-year estimated incidence of T2DM in both groups (male: β = 0.33, p ≤ 0.001 ; female: β = 0.38, p ≤ 0.001 ). The influencing variables were the monthly drinking rate (β = 0.07, p ≤ 0.001 ) and sleep time (β = −0.03, p < 0.05 ) in men and the sedentary time in women (β = 0.03, p < 0.05 ). The overall explanatory power of these variables was 11.3% for men and 14.3% for women. Thus, significant sex differences were found in the 4-year estimated incidence of T2DM. Therefore, intervention programs need to be sex-specific to enhance the efficacy of the interventions in reducing the incidence of T2DM, and such intervention programs should be administered with a strategic approach differentiated by sex.
