Mode differences in a mixed-mode health interview survey among adults

Sociodemographic and behavioural differences between frequent and non-frequent users of convenience food in Germany

Introduction

Convenience foods are a double-edged sword in that they provide quick and easy nutrition but may promote non-communicable diseases related to excess intakes of sugar, fat, and salt. To inform the German national reduction and innovation strategy for less sugar, fat, and salt in processed foods, the present study sought to analyse the consumption frequency of selected convenience foods and to determine sociodemographic and behavioural factors that characterise frequent users.

Methods

In a representative computer-assisted telephone interview survey in the adult German population (N = 3,997) conducted in 2018, consumption frequency of 21 convenience foods was assessed. To characterise frequent in contrast to non-frequent users, data on sociodemographics and behavioural aspects were compared. Statistical analyses comprised chi-square tests with Bonferroni correction as well as Spearman's rank correlation. Cramer's V was used to determine the strength of an association.

Results

Overall and among frequent users (7.7% of the sample) sweet convenience foods and savoury cooking aids were consumed most frequently. Around 75% of the participants indicated little-to-no consumption of 19 of the 21 convenience foods. Male gender (p < 0.001), younger age (p < 0.001), and not having a high level of education (p = 0.017) were identified as key characteristics of frequent users. Furthermore, frequent users were more likely than non-frequent users to live in a family household (p = 0.003) or without a partner (p < 0.001), and to work in shifts (p = 0.002). Additionally, they showed significantly lower cooking skills (p < 0.001).

Conclusion

Public health interventions to limit excess intakes of sugar, fat, and salt from convenience food in Germany should target people of male gender, younger age, and having a lower level of education. On the behavioural side, developing the skills to cook from scratch emerged as major point of focus. Simultaneously, reformulation of the food offer should continue in order to help transition to a more health-promoting food environment.

Prevalence and correlates of androgen dependence: a meta-analysis, meta-regression analysis and qualitative synthesis

PURPOSE OF REVIEW

To investigate the prevalence and correlates of androgen dependence among users. A meta-analysis, meta-regression analysis, and qualitative synthesis were conducted based on a systematic literature search in Google Scholar, ISO Web of Science, PsycNET, and PubMed.

RECENT FINDINGS

Twenty-six studies were included in the review and 18 studies ( N  = 1782) in the statistical analysis. The overall lifetime androgen dependence prevalence was 34.4% [95% confidence interval (CI): 27.8-41.7, Q  = 113.1, I2  = 85.0, P  < 0.001]. Although males (36.1%, P  < 0.001) and females (37.0%, P  = 0.188) did not differ ( Q  = 0.0, P  = 0.930) in dependence prevalence, controlling for other study characteristics, higher study male sample proportion was related to higher dependence prevalence. Combined interview and questionnaire assessments showed higher prevalence compared to interviews only. Publications from 1990-1999 generated higher prevalence compared to 2000-2009 and 2010-2023 publications. Dependents were associated with a wide array of demographic inequalities, and biophysical, cognitive, emotional, and psychosocial problems.

SUMMARY

One of three persons who initiate androgen use experiences dependence along with various serious disorders. Androgen use and dependence should be considered an important public health issue requiring targeted health interventions.

The effect of survey administration mode on youth mental health measures: Social desirability bias and sensitive questions

Aim

Research on trends in youth mental health is used to inform government policy and service funding decisions. It often uses interviewer-administered surveys, which may be affected by mode effects related to social desirability bias. This study sought to determine the impact of survey administration mode on mental health measures, comparing mode effects for sensitive mental health measures (psychological distress and wellbeing) and non-sensitive (physical activity) measures.

Methods

Data were from two large national community samples of young Australians aged 12-25 years conducted in 2020 (N = 6238) and 2022 (N = 4122), which used both interviewer-administered and self-report modes of data collection.

Results

Results showed participants reported lower psychological distress and higher wellbeing in the interviewer-assisted compared with the self-report mode. No mode effects were found for the non-sensitive physical activity measures. No interaction between mode and gender was found, but an age group by mode interaction revealed that those in the 18-21 and 22-25-year age groups were more strongly affected than younger adolescents.

Conclusions

These findings suggest underestimates of mental health issues from interview survey formats, particularly for young adults. The results show how even a weak mode effect can have a large impact on mental health prevalence indicators. Researchers and policy makers need to be aware of the impact social desirability bias can have on mental health measures and consider taking steps to mitigate this effect.

Mental health and well-being in the first year of the COVID-19 pandemic among different population subgroups: evidence from representative longitudinal data in Germany

OBJECTIVES

To examine potential deteriorations in mental health and well-being in the first COVID-19 pandemic year compared with the previous decade focusing on the following vulnerable subgroups in Germany: women with minor children in the household, those living without a partner, younger and older adults, those in a precarious labour market situation, immigrants and refugees, and those with pre-existing physical or mental health risks.

DESIGN

Analyses of secondary longitudinal survey data using cluster-robust pooled ordinary least squares models.

PARTICIPANTS

More than 20 000 individuals (aged 16+ years) in Germany.

PRIMARY AND SECONDARY OUTCOME MEASURES

Mental Component Summary Scale (MCS) of the 12-item Short-Form Health Survey measuring mental health-related quality of life, single item on life satisfaction (LS).

RESULTS

We find a decline in the average MCS in the 2020 survey that is not particularly striking in the overall time course, still resulting in a mean score below those of all preceding waves since 2010. We find no change in LS from 2019 to 2020 against the background of a general upward trend. Regarding vulnerability factors, only the results on age and parenthood are partially in line with our expectations. In 2020, LS declined among the youngest adults; MCS declined among mothers (and women and men without children) but not fathers. Unlike respective comparison groups, refugees, those unemployed before the pandemic and those with pre-existing mental health risks experienced no MCS declines in 2020, whereas persons living without a partner, the eldest, and those with pre-existing health risks exhibited continued increases in LS.

CONCLUSIONS

There is no evidence for substantial breakdowns in mental health or subjective well-being in the first pandemic year in the German population or its subgroups, particularly when considering developments of the previous decade. Since the majority of hypothesised vulnerable groups to pandemic stressors showed more stable MCS and LS, our results warrant further study.

New measures to assess the "Other" three pillars of food security-availability, utilization, and stability

BACKGROUND

In recent reviews of available measures, no existing measures assessed all four pillars of food security and most only assessed one or two pillars-predominantly the access pillar. The purpose of this study was to preliminarily develop novel measures of availability, utilization, and stability that are complementary to the USDA's household food security survey measure (HFSSM).

METHODS

A formative phase included an expert advisory group, literature scans, and interviews with individuals experiencing food insecurity. From April-June 2021, the new measures were piloted in five states (California, Florida, Maryland, North Carolina, and Washington). The cross-sectional pilot survey included the new measures (perceived limited availability, utilization barriers, and food insecurity stability), scales and items for validation (e.g., food security, and self-reported dietary and health outcomes), and demographic questions. Exploratory factor analysis was used to assess dimensionality, internal consistency was assessed using Kuder-Richardson formula 21 (KR21), and convergent and discriminant validity were assessed using Spearman's correlation coefficients. Also, a brief screener version was created for the utilization barriers measure that may be necessary for certain applications (e.g., clinical intake screening to inform referrals to assistance programs).

RESULTS

The analytic samples (perceived limited availability (n = 334); utilization barriers (n = 428); food insecurity stability (n = 445)) were around 45 years old on average, most households had children, over two-thirds were food insecure, over three-fourths were women, and the samples were racially/ethnically diverse. All items loaded highly and unambiguously to a factor (factor loadings range 0.525-0.903). Food insecurity stability showed a four-factor structure, utilization barriers showed a two-factor structure, and perceived limited availability showed a two-factor structure. KR21 metrics ranged from 0.72 to 0.84. Higher scores for the new measures were generally associated with increased food insecurity (rhos = 0.248-0.497), except for one of the food insecurity stability scores. Also, several of the measures were associated with statistically significantly worse health and dietary outcomes.

CONCLUSIONS

The findings support the reliability and construct validity of these new measures within a largely low-income and food insecure sample of households in the United States. Following further testing, such as Confirmatory Factor Analysis in future samples, these measures may be used in various applications to promote a more comprehensive understanding of the food insecurity experience. Such work can help inform novel intervention approaches to address food insecurity more fully.

Assessing targeted invitation and response modes to improve survey participation in a diverse New York City panel: Healthy NYC

BACKGROUND

Healthy NYC is an innovative survey panel created by the New York City (NYC) Department of Health and Mental Hygiene (DOHMH) that offers a cost-effective mechanism for collecting priority and timely health information. Between November 2020 and June 2021, invitations for six different surveys were sent to Healthy NYC panelists by postal mail, email, and text messages. Panelists had the option to complete surveys online or via paper survey.

METHODS

We analyzed whether panelists varied by sociodemographic characteristics based on the contact mode they provided and the type of invitation that led to their response using logistic regression models. Poisson regression models were used to determine whether the number of invitations received before participating in a survey was associated with sociodemographic characteristics.

RESULTS

Younger age and higher education were positively associated with providing an email or text contact. Furthermore, age, race, and income were significant predictors for invitation modes that led to a survey response. Black panelists had 72% greater odds (OR 1.72 95% CI: 1.11-2.68) of responding to a mail invite and 33% lesser odds (OR 0.67, 95% CI: 0.54-0.83) of responding to an email invite compared with White panelists. Additionally, in five of the six surveys, more than half of the respondents completed surveys after two invites. Email invitations garnered the highest participation rates.

CONCLUSIONS

We recommend using targeted invitation modes as an additional strategy to improve participation in panels. For lower-income panelists who do not provide an email address, it may be reasonable to offer additional response options that do not require internet access. Our study's findings provide insight into how panels can tailor outreach to panelists, especially among underrepresented groups, in the most economical and efficient ways.

Magnitude of depression and its associated factors among patients with diabetes mellitus at public hospitals in Southwest Ethiopia, 2021

Depression is the third-leading cause of disability measured in terms of disability-adjusted life-years. When depression coexists with diabetes mellitus, it is associated with major health consequences and results in poor health outcomes, decreased quality of life, lost productivity and increased risk of death. The current study aimed to assess the magnitude of depression and its associated factors among adult patients with diabetes mellitus attending follow-up at the public hospitals of Buno Bedele zone, Southwest Ethiopia. A multi-centre cross-sectional study was done among people living with diabetes mellitus at an outpatient clinic of Buno Bedele zone hospitals. The study period was from April to May 2021. A systematic random sampling technique was used to select the study participants. Data were collected using a structured questionnaire. Depression was assessed by the Patient Health Questionnaire-9. Patient Health Questionnaire-9 is a validated tool to assess depression with sensitivity 86% and specificity 67%. The collected data were cleaned, edited, and entered into epi-data version 3.1, and analysed using SPSS version 24. Logistic regression analysis was employed to identify factors associated with depression occurrence. A p value of 0.05 was considered statistically significant. A total of 310 study participants were included in this study. Among study participants, 41.6% fulfilled the criteria for depression. Variables significantly associated with depression were female gender [AOR: 2.26, 95% CI (1.30, 3.95)], duration of diabetes greater than 5 years [AOR: 2.68, 95% CI (1.57, 4.56)], poor social support [AOR: 2.46, 95% CI (1.10, 5.49)], moderate social support [AOR: 2.63, 95% CI (1.34, 5.16)], current alcohol consumption [AOR: 3.55, 95% CI (1.20, 10.52)] and previous alcohol consumption [AOR = 2.81, 95% CI (1.40, 5.60)]. According to this study, depression is relatively common among diabetic individuals. Being a female, having diabetes for a long time, having poor social support, using alcohol now and in the past were factors that substantially linked to depression. Healthcare professionals should consider screening for depression using the Patient Health Questionnaire-9 or other validated tools in all diabetic patients, especially in those who are at higher risk.

Development of three new multidimensional measures to assess household food insecurity resilience in the United States

Introduction

This study aimed to develop and test novel self-administered measures (Absorptive capacity, Adaptive capacity, and Transformative capacity) of three aspects of a household's resilience to financial shocks (e.g., job loss) that can increase food insecurity risk.

Methods

Measures were piloted in a convenience sample of households at risk for food insecurity in the United States. The survey included the new measures, validation variables (financial shock, household food security, general health, personal resilience to challenges, and financial wellbeing), and demographic questions. Exploratory factor analysis was used to assess dimensionality, internal consistency was assessed [Cronbach's alpha (CA)], and construct validity was assessed (Spearman's correlation). Also, brief screener versions of the full measures were created.

Results

Participants in the analytic samples (n = 220-394) averaged 44 years old, 67% experienced food insecurity, 47% had a high school diploma or less, 72% were women, and the sample was racially/ethnically diverse. Scores for Absorptive capacity [one factor; CA = 0.70; Mean = 1.32 (SD = 0.54)], Adaptive capacity [three factors; CAs 0.83-0.90; Mean = 2.63 (SD = 0.85)], and Transformative capacity [three factors; CAs 0.87-0.95; Mean = 2.70 (SD = 1.10)] were negatively associated with financial shocks (-0.221 to -0.307) and positively associated with food insecurity (0.310-0.550) general health (0.255-0.320), personal resilience (0.231-0.384), and financial wellbeing (0.401-0.474).

Discussion

These findings are encouraging and support reliability and validity of these new measures within this sample. Following further testing, such as Confirmatory Factor Analysis in future samples, these measures may prove useful for needs assessments, program evaluation, intake screening, and research/surveillance. Widespread adoption in the future may promote a more comprehensive understanding of the food insecurity experience and facilitate development of tailored interventions on upstream causes of food insecurity.

[Health Literacy Among German Health Professionals-To-Be - Exploratory Pilot Study]

OBJECTIVE

Health literacy is defined as the ability to collect, understand, evaluate and use health information. Previous studies have shown that the German population has only an average level of health literacy. Health professionals such as nurses, doctors or midwives need to be health literate themselves to promote patients' health literacy, as well as to protect and promote their own health. So far, there is a lack of research about health literacy among health professionals in Germany. The objective of this study was to assess the health literacy of health professionals.

METHOD

The study involved 583 participants from the final year classes of the DHBW Stuttgart and dual cooperation partners (vocational schools and academic teaching hospitals). These included graduates of nursing, midwifery and therapy (physiotherapy/logo-/occupational therapy), as well as management in health care and medical students in their practical year. The questionnaire HLS-EU-Q16 was used to record health literacy. By means of 16 questions, the participants rated on a 4-point scale how easy or difficult it was for them to find, understand, assess and implement health-related information.

RESULTS

The study showed that only 30.1% of the participants had sufficient health literacy; 48.9% of the participants showed problematic health literacy, 21.0% inadequate health literacy. The analysis of the individual questions showed that, in almost all areas, paticipants reported more problems in finding, understanding, assessing and implementing health-related information than respondents in other European countries.

CONCLUSIONS

The present study shows that young health professionals have limited health literacy. Further research is needed to obtain a more comprehensive and differentiated picture of health literacy among health professionals. Health literacy skills and competencies should be systematically introduced in health professions-related study curricula, as well as in bedside training.

Organizing the health interview survey at the local level: design of a pilot study

Background

The local Health Interview Study (LHIS) was developed to gain health information at the level of the municipality in Flanders, the northern part of Belgium. It enables municipalities to make evidence-based decisions in their public health policy. To test the feasibility of implementing the LHIS, a pilot study was conducted in Melle, a small Flemish municipality with 11.736 inhabitants.

Methods

The target sample size was 1000 (≥ 15 years). A systematic sampling technique was applied with substitutes for non-respondents who were matched in terms of statistical sector, age and sex. Selected persons were contacted by post to complete the questionnaire and in case of non-response, a reminder was sent. Questionnaires were collected using a concurrent mixed-mode design: a paper and pencil, and web option. All questions were selected from the Belgian Health Interview Survey relating to health status and determinants of health.

Results

One thousand twenty-two questionnaires were obtained after inviting 3137 individuals (response rate = 32.6%). Older adults were more likely to participate than younger adults, and women more than men. The final sample resembled the initial sample in terms of sex and statistical sector, but not in terms of age. Younger adults were underrepresented whereas older adults were overrepresented. Lastly, older adults were more likely to fill in the questionnaire on paper than younger adults, and women more than men.

Conclusion

The LHIS can be successfully implemented in Flemish municipalities. The method, however, does not guarantee that the composition of the final sample reflects the initial sample. Therefore, weights should be added in the analyses to correct for potential deviations in sample composition. Furthermore, implementing a sequential mixed-mode design with a web option preceding a paper and pencil option in future studies could reduce costs and improve data quality.

Development of 2 Short Patient-Report Questionnaires of Patient Safety in Primary Care

OBJECTIVES

The Patient Reported Experiences and Outcomes of Safety in Primary Care (PREOS-PC) is a valid and reliable instrument (61 items across 5 domains) of patients' perceptions of safety. Stakeholder feedback has supported shorter versions for improving choice and facilitating uptake of routine patient-centered evaluation. We sought to develop 2 shorter versions of PREOS-PC: one including the shortest possible scales that met established measurement performance standards and a screening version including a single item per domain.

METHODS

A total of 1244 patients from 45 general practices across England completed PREOS-PC questionnaires. All scale items in PREOS-PC underwent Item Response Theory analysis, applying standard criteria for the item reduction. Cognitive debriefing from 10 patient interviews allowed for the assessment of the instruments' readability. The instruments' psychometrics properties were reassessed in a validation sample of 1557 patients in 21 English general practices.

RESULTS

"PREOS-PC Compact" includes 25 items and 2 open-ended questions across the 5 domains, 44% of the length of the original instrument. "PREOS-PC Screen" consists of 6 items: the best-performing single items for 2 domains, 1 item modified from original items for each of the remaining 3 domains, and 1 open-ended question. The evaluation of the instruments confirmed they were acceptable to patients and met standards for readability; construct, convergent, and divergent validity; and reliability.

CONCLUSIONS

PREOS-PC Compact meets high-performance standards while reducing patient burden for routine monitoring of patient safety in primary care. PREOS-PC Screen is a concise tool apt for incorporation into audits and to target more in-depth review as needed.

Using online spaces to recruit Kenyan queer womxn and trans men in restrictive offline settings

BACKGROUND

Understanding and addressing healthcare and service delivery inequalities is essential to increase equity and overcome health disparities and service access discrimination. While tremendous progress has been made towards the inclusion of sexual and gender minorities in health and other research, gaps still exist. Innovative methods are needed to close these. This case study describes and reflects on using online-based data collection to ascertain sexual health decision-making and health service utilisation among Kenyan queer womxn and trans men.

METHODS

Case study The study used a mixed-methods approach in two phases with triangulated quantitative and qualitative elements. Both elements used web-based technology to gather data.

RESULTS

Using online spaces to recruit and collect data from queer womxn and trans men exceeded expectations. A total of 360 queer womxn and trans men responded to the digitally distributed survey, and 33 people, queer womxn and trans men, as well as key informants, participated in the interviews, which were primarily conducted on Zoom and Skype. The case study analyses the risks and benefits of this approach and concludes that online sampling approaches can mitigate risks and enable effective and safe sampling of a marginalised group in a restrictive legal setting: Kenyan queer womxn and trans men.

CONCLUSION

Using online spaces when researching marginalised populations could effectively overcome risks around stigma, discrimination and violence. It could be an effective way to understand these populations' healthcare needs better. Factors contributing to success included building trusting relationships with key members of the community, strategic and opportune timing, a nuanced understanding of the mobile landscape, and carefully chosen safety and security measures. However, it should be noted that conducting research online could increase the risk of further marginalising and excluding those without access to web-based technology.

ASK ME!-Routine measurement of patient experience with patient safety in ambulatory care: A mixed-mode survey

Objective

Routine measurement of patient safety from the patients’ perspective receives increasing attention as an important component of safety measurement systems. The aim of this study was to examine patients’ experience with patient safety in ambulatory care and the results’ implications for routine patient safety measurement in ambulatory care.

Design

Cross-sectional mixed-mode survey.

Setting

General practitioner and specialist practices.

Participants

Patients aged >18 years seeking care in ambulatory care practices between February and June 2020.

Methods

A 22-item-questionnaire was completed in the practice or at home either on paper or online. Multivariate logistic regression was used to analyse the influence of survey mode and patient characteristics on patient experience with patient safety.

Results

The overall response rate was 71.1%. Most patients completed the questionnaire on site (76.6%) and on paper (96.1%). Between 30.1% to 68.5% of the respondents report the most positive option for patient experience with the main domains of patient safety. A total of 2.9% of patients reported having experienced a patient-safety event (PSE) during the last 12 months. Patients who filled in the questionnaire off site were more likely to report negative experiences for the scales communication & information (OR 1.2, 95% CI 1.0–1.5), rapport & participation (OR 1.4, 95% CI 1.1–1.7) and access (OR 1.3, 95% CI 0.9–1.4) than those who completed it on site. Those who chose a paper questionnaire were more likely to report negative experiences for all five scales compared to web responders.

Conclusion

Routine measurement of patient experience with factors contributing to the occurrence of PSEs can achieve high response rates by offering flexible participation options. Results gained from mixed-mode surveys need to take mode-effects into account when interpreting and using the results. Further research is needed in how to adequately assess number and type of experienced events in routine measurements.

German Health Update (GEDA 2019/2020-EHIS) - Background and methodology

Between April 2019 and September 2020, 23,001 people aged 15 or over responded to questions about their health and living conditions for the German Health Update (GEDA 2019/2020-EHIS). The results are representative of the German resident population aged 15 or above. The response rate was 21.6%. The study used a questionnaire based on the third wave of the European Health Interview Survey (EHIS), which was carried out in all EU member states. EHIS consists of four modules on health status, health care provision, health determinants, and socioeconomic variables. The data are collected in a harmonised manner and therefore have a high degree of international comparability. They constitute an important source of information for European health policy and health reporting and are made available by the Statistical Office of the European Union (Eurostat). They also form the basis of the Federal Health Reporting undertaken in Germany. Data collection began in April 2019, just under a year before the beginning of the SARS-CoV-2 pandemic, and continued into its initial phase, as of March 2020. As such, data from the current GEDA wave can also be used to conduct research into the health impact of the SARS-CoV-2 pandemic.

The Danish Health and Wellbeing Survey: Study design, response proportion and respondent characteristics

AIMS

This study aimed to describe the study design and respondent characteristics (including non-response analyses) of the Danish Health and Wellbeing Surveys in 2015 and 2019 and a follow-up survey that was carried out during the COVID-19 pandemic in 2020.

METHODS

The Danish Health and Wellbeing Survey is the Danish part of the European Health Interview Survey (EHIS). The samples in 2015 (N=12,000) and 2019 (N=14,000) were both based on a simple random selection of individuals aged ⩾15 years from the Danish Civil Registration System. All individuals from the sample in 2019 who were still alive and living in Denmark were reinvited for a follow-up survey in 2020 (N=13,474). Data in all surveys were collected via self-administered questionnaires (web or paper based). The questionnaires in 2015 and 2019 included the EHIS model questionnaire as well as national questions, whereas the questionnaire in 2020 mainly focused on physical and mental health, employment and working lives, and health behaviour.

RESULTS

The overall response proportion declined slightly between 2015 (48.4%) and 2019 (47.4%) but went up to 49.8% in the follow-up survey in 2020. Unit non-response was associated with, for example, male sex, younger age, being unmarried and lower educational level but not with degree of urbanisation. In all, 5000 individuals completed the questionnaire in both 2019 and 2020.

CONCLUSIONS

The results are in line with most previous research on non-response in health surveys. However, an association between degree of urbanisation and non-response has been suggested in previous studies. This association was not found in our study.

A multi-state evaluation of the association between mental health and firearm storage practices

Firearm storage method is a potentially modifiable risk factor for suicide. Using data from a large, multi-state survey, we sought to determine whether there is an association between mental health and household firearm storage practices, and characterize that association by state of residence. Participants who endorsed the presence of a household firearm and answered the mental health questions in the 2016-2017 Behavioral Risk Factor Surveillance System from eight states were included (n=26,949). Exposures were recent poor mental health (≥14 vs. 0-13 days/past month), and diagnosis of depression. Outcomes were household firearm storage practices (loaded, and both loaded and unlocked). Using Poisson regression, we calculated adjusted prevalence ratios (aPR) overall and stratified by state of residence. Of adults endorsing a household firearm, 35.1% reported storing a firearm loaded, and of those, 53.4% reported that the firearm was both loaded and unlocked. Neither recent poor mental health nor depression was associated with loaded (aPR 1.14 [95% CI: 0.95-1.37] and aPR 0.94 [95% CI 0.80-1.09], respectively) or loaded and unlocked (aPR 1.08 [95% CI 0.88-1.42] and aPR 1.04 [95% CI 0.88-1.22], respectively) firearm storage. In the setting of highly prevalent loaded firearm storage, no differences in storage practices by mental health indicators were observed across eight states despite disparate firearm policies and local culture. The lack of difference in storage practices by mental health indicators across several states highlights an opportunity to improve means safety counseling practices, and the need for dedicated evaluation of state-level firearm storage policies.

The Danish National Health Survey: Study design, response rate and respondent characteristics in 2010, 2013 and 2017

Aim: This article aims to describe the study design, including descriptive statistics on changes in response rates, characteristics associated with response and response mode distribution, in the Danish National Health Survey (DNHS) in 2010, 2013 and 2017. Methods: Each survey was based on five regional stratified random samples and one national random sample drawn from the Danish Civil Registration System. The subsamples were mutually exclusive. Around 300,000 individuals (aged ⩾16 years) were invited to participate in each survey using a mixed-mode approach (paper/web). A questionnaire with a minimum of 52 questions was used in all subsamples. In 2010 and 2013, invitations were sent via the regular postal service, whereas a secure electronical mail service was used to invite the majority (around 90%) in 2017. Weights accounted for survey design and non-response. Results: Participation decreased from 59.5% in 2010 to 54.0% in 2013 after which it increased to 58.7% in 2017. The proportion answering the web questionnaire increased from 31.0% to 77.4% between 2013 and 2017 and varied from 73.8% to 79.7% between the subsamples in 2017. Overall, the response rate was low among young men and old women and among individuals who were unmarried, had low sociodemographic status, were from ethnic minority backgrounds or were living in the eastern part of Denmark. Conclusions: The survey mode, response mode distribution as well as response rate have changed over time. Weights to handle non-response can be applied to accommodate possible problems in generalising the results. However, efforts should continuously be made to ensure that response is missing at random.

Comparing web-based versus face-to-face and paper-and-pencil questionnaire data collected through two Belgian health surveys

OBJECTIVES

Using the European Health Interview Survey (EHIS) questionnaire, a web-based survey was organized alongside a face-to-face (F2F) survey including a paper-and-pencil (P&P) questionnaire for sensitive topics. Associated with these different modes, other design features varied too (e.g., recruitment, incentives, sampling). We assessed whether these whole data collection systems developed around the modes produced equivalent health estimates.

METHODS

Data were obtained from two population-based surveys: the EHISWEB (web-administered, n = 1010) and the Belgian Health Interview Survey 2018 (BHIS2018) (interviewer-administered, n = 2748). Logistic regression analyses were used to assess mode system differences while adjusting for socio-demographic differences in the net samples.

RESULTS

For the P&P mode of the BHIS, significant mode system differences were detected for 2 of the 9 health indicators. Among the indicators collected via the F2F mode, 9 of the 18 indicators showed significant differences.

CONCLUSIONS

Indicators collected via the web-based and P&P self-administered modes were generally more comparable than indicators collected via the web-based and F2F mode. Furthermore, fewer differences were detected for indicators based on simple and factual questions compared to indicators based on subjective or complex questions.

Educational differences in the prevalence of behavioural risk factors in Germany and the EU - Results from the European Health Interview Survey (EHIS) 2

This article examines educational differences in the prevalence of behavioural risk factors among adults and compares the results for Germany with the average from the European Union (EU). Data were derived from the second wave of the European Health Interview Survey, which took place between 2013 and 2015 (EHIS 2). Analyses were conducted using a regression-based calculation of relative and absolute educational differences in the prevalence of behavioural risk factors, based on self-reported data from women and men aged between 25 and 69 (n=217,215). Current smoking, obesity, physical activity lasting less than 150 minutes per week, heavy episodic drinking and non-daily fruit or vegetable intake are more prevalent among people with a low education level than those with a high education level. This applies to Germany as well as the EU average. Overall, the relative educational differences identified for these risk factors place Germany in the mid-range compared to the EU average. However, relative educational differences in current smoking and heavy episodic drinking are more manifest among women in Germany than the EU average, with the same applying to low physical activity among men. In contrast, relative educational differences in non-daily fruit or vegetable intake are less pronounced among women and men in Germany than the average across the EU. Increased efforts are needed in various policy fields to improve the structural conditions underlying health behaviour, particularly for socially disadvantaged groups, and increase health equity.

[Trends in smoking among adults in Germany : Evidence from seven population-based health surveys from 1991-2015]

BACKGROUND

Despite decreasing smoking prevalence, tobacco use remains a key public health problem in Germany. For planning, managing, and evaluating tobacco control measures, regular data collection on smoking behavior in the population is essential. The aim of this article is to present trends in adult tobacco use since the early 1990s based on data from the health monitoring of the Robert Koch-Institute (RKI).

METHODS

Analyses are based on data from 106,158 individuals aged 18 to 79 years, who participated in seven RKI health surveys from 1991-2015. Trends in tobacco consumption were analyzed using different indicators of smoking behavior, stratified by age, cohort, and gender.

RESULTS

An overall falling smoking prevalence can be attributed primarily to a significant decline in the younger age groups since the early 2000s. Trend analysis by cohort reveals a declining prevalence for almost all cohorts over time from 1991-2015. Historically there has been is a sharp increase in the prevalence of women who have ever smoked between the 1930-1934 and 1950-1959 cohorts. The proportion of men who have ever smoked slightly decreased between the 1930-1934 and 1980-1984 cohorts.

DISCUSSION

The shown overall decline happened concurrently with various tobacco prevention measures implemented during this period in Germany. If present trends related to continuous high smoking rates are sustained, it can be assumed that the tobacco consumption of the population will remain the source of adverse health outcomes. Accordingly, tobacco prevention measures and the promotion of smoking cessation in all age groups should be a public health priority.

Can targeted cover letters improve participation in health surveys? Results from a randomized controlled trial

Background

Improving response rates in epidemiologic studies is important for the generalizability of the outcome. The aim of this study was to examine whether it can be advantageous for participation to target different versions of the cover letters to different sample subgroups.

Methods

A randomized trial was incorporated in a cross-sectional health survey in Denmark (n = 25,000) where a motivational sentence in the cover letter intended to heighten perceptions of relevance of the survey was varied among 11 sample subgroups (treatment groups). Ten different versions of a sentence outlining questionnaire themes were tested: each mentioned three out of five themes: stress, alcohol, sex, sleep problems, and contact with family and friends. An eleventh group, the control group, omitted this sentence.

Results

On average, the additional motivational sentence resulted in a significantly lower response rate overall compared to the control group. However, the additional motivational sentence was found to have heterogeneous effects on survey response. Furthermore, the nature of the heterogeneity differed between the versions of the sentence. Specifically, the additional sentence tended to produce a higher response rate among the youngest age group and a lower response rate in the oldest age group compared to the generic letter. The use of alcohol in the motivational sentence tended to have a positive effect on response in the age group 16–24 years, and stress tended to have a positive effect in the age group ≥65 years. On the contrary, sex tended to have a negative effect in the age groups 45–64 years and ≥ 65 years. However, a significant interaction was only found between the use of stress and age group (p = < 0.0001).

Conclusion

The findings of significant and heterogeneous effects suggest that there is potential for a targeted approach to improve both response rates and sample composition. The uneven effect of the separate themes across age groups suggests that the selection of themes to be included in the motivational sentence is important for the use of targeted appeals to be successful and warrants further research to better identify which themes works in which contexts, in which subgroups and under which circumstances.

Intergenerational Educational Pathways and Self-Rated Health in Adolescence and Young Adulthood: Results of the German KiGGS Cohort

Health differences in social mobility are often analysed by income differences or different occupational positions. However, in early adulthood many young people still have very diffuse income situations and are not always fully integrated into the labour market despite many having finished school. This article focusses on the link between intergenerational educational pathways and self-rated health (SRH) among young adults considering their SRH in adolescence. The data source used is the German KiGGS cohort study. The analysis sample comprises 2175 young people at baseline (t0: 2003⁻2006 age 14⁻17) and first follow-up (t1: 2009⁻2012 age 19⁻24). Combining parent's and young people's highest school degree, the data can trace patterns of intergenerational educational pathways (constant high level of education, upward mobility, downward mobility, constant low level of education). Young people's SRH was recorded at t0 and t1. During adolescence and young adulthood, participants were less likely to report poor SRH if they had a constant high intergenerational education or if they were upwardly mobile. The differences were particularly striking among young adults: average marginal effects (AME) for poor SRH showed much higher risk among downwardly mobile compared to peers with an intergenerational constant high education (AME: 0.175 [0.099; 0.251]), while the upwardly mobile had a significantly lower risk for less than good SRH than peers with an intergenerational constant low level of education (AME: -0.058 [-0.113; -0.004]). In the context of great societal demands and personal developmental needs, educational differences in health tend to increase in young adulthood. Public Health should pay more attention to educational and health inequalities in young adulthood.

The subjective health of adults in Germany

The term 'subjective health' reflects not only existing illnesses and health complaints, but particularly emphasizes the personal well-being. Studies often collect data on subjective health by asking participants to provide self-assessments of their general state of health. This was also the case with GEDA 2014/2015-EHIS, which employed the internationally renowned Minimum European Health Module (MEHM) as part of the study. Its results demonstrate that 68.2% of adults in Germany rate their general health as very good or good, with the remaining 31.8% rating it as fair, poor or very poor. The proportion of women who rate their general health as very good or good is slightly lower than the proportion of men who do so (66.6% compared to 69.9%). With increasing age, women and men view the condition of their general health as worsening. The study also identified educational differences which showed that men and women with low levels of education tend to rate their health worse compared to self-assessments provided by women and men with higher levels of education, and in some cases also regional differences.

Measurement agreement of the self-administered questionnaire of the Belgian Health Interview Survey: Paper-and-pencil versus web-based mode

Before organizing mixed-mode data collection for the self-administered questionnaire of the Belgian Health Interview Survey, measurement effects between the paper-and-pencil and the web-based questionnaire were evaluated. A two-period cross-over study was organized with a sample of 149 employees of two Belgian research institutes (age range 22–62 years, 72% female). Measurement agreement was assessed for a diverse range of health indicators related to general health, mental and psychosocial health, health behaviors and prevention with kappa coefficients and intraclass correlation (ICC). The quality of the data collected by both modes was evaluated by quantifying the missing, ‘don’t know’ and inconsistent values and data entry mistakes. Good to very good agreement was found for all categorical indicators with kappa coefficients superior to 0.60, except for two mental and psychosocial health indicators namely the presence of a sleeping disorder and of a depressive disorder (kappa≥0.50). For the continuous indicators high to acceptable agreement was observed with ICC superior to 0.70. Inconsistent answers and data-entry mistakes were only occurring in the paper-and-pencil mode. There were no less missing values in the web-based mode compared to the paper-and-pencil mode. The study supports the idea that web-based modes provide, in general, equal responses to paper-and-pencil modes. However, health indicators based upon factual and objective items tend to have higher measurement agreement than indicators requiring an assessment of personal subjective feelings. A web-based mode greatly facilitates the data-entry process and guides the completing of a questionnaire. However, item non-response was not positively affected.

Mode Equivalence of Health Indicators Between Data Collection Modes and Mixed-Mode Survey Designs in Population-Based Health Interview Surveys for Children and Adolescents: Methodological Study

BACKGROUND

The implementation of an Internet option in an existing public health interview survey using a mixed-mode design is attractive because of lower costs and faster data availability. Additionally, mixed-mode surveys can increase response rates and improve sample composition. However, mixed-mode designs can increase the risk of measurement error (mode effects).

OBJECTIVE

This study aimed to determine whether the prevalence rates or mean values of self- and parent-reported health indicators for children and adolescents aged 0-17 years differ between self-administered paper-based questionnaires (SAQ-paper) and self-administered Web-based questionnaires (SAQ-Web), as well as between a single-mode control group and different mixed-mode groups.

METHODS

Data were collected for a methodological pilot of the third wave of the "German Health Interview and Examination Survey for Children and Adolescents". Questionnaires were completed by parents or adolescents. A population-based sample of 11,140 children and adolescents aged 0-17 years was randomly allocated to 4 survey designs-a single-mode control group with paper-and-pencil questionnaires only (n=970 parents, n=343 adolescents)-and 3 mixed-mode designs, all of which offered Web-based questionnaire options. In the concurrent mixed-mode design, both questionnaires were offered at the same time (n=946 parents, n=290 adolescents); in the sequential mixed-mode design, the SAQ-Web was sent first, followed by the paper questionnaire along with a reminder (n=854 parents, n=269 adolescents); and in the preselect mixed-mode design, both options were offered and the respondents were asked to request the desired type of questionnaire (n=698 parents, n=292 adolescents). In total, 3468 questionnaires of parents of children aged 0-17 years (SAQ-Web: n=708; SAQ-paper: n=2760) and 1194 questionnaires of adolescents aged 11-17 years (SAQ-Web: n=299; SAQ-paper: n=895) were analyzed. Sociodemographic characteristics and a broad range of health indicators for children and adolescents were compared by survey design and data collection mode by calculating predictive margins from regression models.

RESULTS

There were no statistically significant differences in sociodemographic characteristics or health indicators between the single-mode control group and any of the mixed-mode survey designs. Differences in sociodemographic characteristics between SAQ-Web and SAQ-paper were found. Web respondents were more likely to be male, have higher levels of education, and higher household income compared with paper respondents. After adjusting for sociodemographic characteristics, only one of the 38 analyzed health indicators showed different prevalence rates between the data collection modes, with a higher prevalence rate for lifetime alcohol consumption among the online-responding adolescents (P<.001).

CONCLUSIONS

These results suggest that mode bias is limited in health interview surveys for children and adolescents using a mixed-mode design with Web-based and paper questionnaires.

New mothers' feelings of disappointment and failure after cesarean delivery

BACKGROUND

Childbirth is an important life event and how women feel in retrospect about their first childbirth may have long-term effects on the mother, child, and family. In this study, we investigated the association between mode of delivery at first childbirth and birth experience, using a new scale developed specifically to measure women's affective response.

METHODS

This was a prospective cohort study of 3006 women who were interviewed during pregnancy and 1-month postpartum. The First Baby Study Birth Experience Scale was used to measure the association between mode of delivery and women's postpartum feelings about their childbirth, taking into account relevant confounders, including maternal age, race, education, pregnancy intendedness, depression, social support, and maternal and newborn complications by way of linear and logistic regression models.

RESULTS

Women who had unplanned cesarean delivery had the least positive feelings overall about their first childbirth, in comparison to those whose deliveries were spontaneous vaginal (P < .001), instrumental vaginal (P = .001), and planned cesarean (P < .001). In addition, those who delivered by unplanned cesarean were more likely to feel disappointed (adjusted odds ratio [OR] 6.21 [95% confidence interval (CI) 4.62-8.35]) and like a failure (adjusted OR 5.09 [95% CI 3.65-7.09]) in comparison to women who had spontaneous vaginal delivery; and less likely to feel extremely or quite a bit proud of themselves (adjusted OR 2.70 [95% CI 2.20-3.30]).

CONCLUSIONS

Delivering by unplanned cesarean delivery adversely affects how women feel about their first childbirth in retrospect, and their self-esteem.

Mixing modes in a population-based interview survey: comparison of a sequential and a concurrent mixed-mode design for public health research

Background

Population-based surveys currently face the problem of decreasing response rates. Mixed-mode designs are now being implemented more often to account for this, to improve sample composition and to reduce overall costs. This study examines whether a concurrent or sequential mixed-mode design achieves better results on a number of indicators of survey quality.

Methods

Data were obtained from a population-based health interview survey of adults in Germany that was conducted as a methodological pilot study as part of the German Health Update (GEDA). Participants were randomly allocated to one of two surveys; each of the surveys had a different design. In the concurrent mixed-mode design (n = 617) two types of self-administered questionnaires (SAQ-Web and SAQ-Paper) and computer-assisted telephone interviewing were offered simultaneously to the respondents along with the invitation to participate. In the sequential mixed-mode design (n = 561), SAQ-Web was initially provided, followed by SAQ-Paper, with an option for a telephone interview being sent out together with the reminders at a later date. Finally, this study compared the response rates, sample composition, health indicators, item non-response, the scope of fieldwork and the costs of both designs.

Results

No systematic differences were identified between the two mixed-mode designs in terms of response rates, the socio-demographic characteristics of the achieved samples, or the prevalence rates of the health indicators under study. The sequential design gained a higher rate of online respondents. Very few telephone interviews were conducted for either design. With regard to data quality, the sequential design (which had more online respondents) showed less item non-response. There were minor differences between the designs in terms of their costs. Postage and printing costs were lower in the concurrent design, but labour costs were lower in the sequential design. No differences in health indicators were found between the two designs. Modelling these results for higher response rates and larger net sample sizes indicated that the sequential design was more cost and time-effective.

Conclusions

This study contributes to the research available on implementing mixed-mode designs as part of public health surveys. Our findings show that SAQ-Paper and SAQ-Web questionnaires can be combined effectively. Sequential mixed-mode designs with higher rates of online respondents may be of greater benefit to studies with larger net sample sizes than concurrent mixed-mode designs.

Socioeconomic Inequalities in Health and Perceived Unmet Needs for Healthcare among the Elderly in Germany

Research into health inequalities in the elderly population of Germany is relatively scarce. This study examines socioeconomic inequalities in health and perceived unmet needs for healthcare and explores the dynamics of health inequalities with age among elderly people in Germany. Data were derived from the Robert Koch Institute's cross-sectional German Health Update study. The sample was restricted to participants aged 50-85 years (n = 11,811). Socioeconomic status (SES) was measured based on education, (former) occupation, and income. Odds ratios and prevalence differences were estimated using logistic regression and linear probability models, respectively. Our results show that self-reported health problems were more prevalent among men and women with lower SES. The extent of SES-related health inequalities decreased at older ages, predominantly among men. Although the prevalence of perceived unmet needs for healthcare was low overall, low SES was associated with higher perceptions of unmet needs in both sexes and for several kinds of health services. In conclusion, socioeconomic inequalities in health exist in a late working age and early retirement but may narrow at older ages, particularly among men. Socially disadvantaged elderly people perceive greater barriers to accessing healthcare services than those who are better off.

Implementation of the European health interview survey (EHIS) into the German health update (GEDA)

Background

This methodological paper describes the integration of the ‘European Health Interview Survey wave 2’ (EHIS 2) into the ‘German Health Update’ 2014/2015 (GEDA 2014/2015-EHIS).

Methods

GEDA 2014/2015-EHIS is a cross-sectional health survey. A two-stage stratified cluster sampling approach was used to recruit persons aged 15 years and older with permanent residence in Germany. Two different modes of data collection were used, self-administered web questionnaire and self-administered paper questionnaire. The survey instrument implemented the EHIS 2 modules on health status, health care use, health determinants and social background variables and additional national questions. Data processing was conducted according to the quality and validation rules specified by Eurostat.

Results

In total, 24,824 questionnaires were completed. The response rate was 27.6%. The two-stage cluster sample method seems to have been successful in achieving a sample with high representativeness. The final micro data file was inspected, approved and certified by Eurostat. Access to micro data of the EHIS 2 can be provided by Eurostat via research contract and to the GEDA 2014/2015-EHIS public use file by the Research Data Centre of the Robert Koch Institute. First EHIS 2 results are available at the Eurostat website.

Conclusions

Integrating a multinational health survey into an existing national health monitoring system was a challenge in Germany. The national survey methodology for conducting the survey had to be further developed in order to meet the overarching goal of harmonizing the health information from national statistical offices and public health research institutes across the European Union. The harmonized EHIS 2 data source will profoundly impact international public health research in the near future. The next EHIS wave 3 will be conducted around 2019.

Mind the Mode: Differences in Paper vs. Web-Based Survey Modes Among Women With Cancer

CONTEXT

Researchers administering surveys seek to balance data quality, sources of error, and practical concerns when selecting an administration mode. Rarely are decisions about survey administration based on the background of study participants, although socio-demographic characteristics like age, education, and race may contribute to participants' (non)responses.

OBJECTIVES

In this study, we describe differences in paper- and web-based surveys administered in a national cancer survivor study of women with a history of cancer to compare the ability of each survey administrative mode to provide quality, generalizable data.

METHODS

We compared paper- and web-based survey data by socio-demographic characteristics of respondents, missing data rates, scores on primary outcome measure, and administrative costs and time using descriptive statistics, tests of mean group differences, and linear regression.

RESULTS

Our findings indicate that more potentially vulnerable patients preferred paper questionnaires and that data quality, responses, and costs significantly varied by mode and participants' demographic information. We provide targeted suggestions for researchers conducting survey research to reduce survey error and increase generalizability of study results to the patient population of interest.

CONCLUSION

Researchers must carefully weigh the pros and cons of survey administration modes to ensure a representative sample and high-quality data.

Home safe home: Evaluation of a childhood home safety program

BACKGROUND

The London Health Sciences Centre Home Safety Program (HSP) provides safety devices, education, a safety video, and home safety checklist to all first-time parents for the reduction of childhood home injuries. The objective of this study was to evaluate the HSP for the prevention of home injuries in children up to 2 years of age.

METHODS

A program evaluation was performed with follow-up survey, along with an interrupted time series analysis of emergency department (ED) visits for home injuries 5 years before (2007-2013) and 2 years after (2013-2015) implementation. Spatial analysis of ED visits was undertaken to assess differences in home injury rates by dissemination areas controlling differences in socioeconomic status (i.e., income, education, and lone-parent status) at the neighborhood level.

RESULTS

A total of 3,458 first-time parents participated in the HSP (a 74% compliance rate). Of these, 20% (n = 696) of parents responded to our questionnaire, with 94% reporting the program to be useful (median, 6; interquartile range, 2 on a 7-point Likert scale) and 81% learning new strategies for preventing home injuries. The median age of the respondent's babies were 12 months (interquartile range, 1). The home safety check list was used by 87% of respondents to identify hazards in their home, with 95% taking action to minimize the risk. The time series analysis demonstrated a significant decline in ED visits for home injuries in toddlers younger than2 years of age after HSP implementation. The declines in ED visits for home injuries remained significant over and above each socioeconomic status covariate.

CONCLUSION

Removing hazards, supervision, and installing safety devices are key facilitators in the reduction of home injuries. Parents found the HSP useful to identify hazards, learn new strategies, build confidence, and provide safety products. Initial finding suggests that the program is effective in reducing home injuries in children up to 2 years of age.

Changing educational inequalities in sporting inactivity among adults in Germany: a trend study from 2003 to 2012

BACKGROUND

Social inequalities in health can be explained in part by the social patterning of leisure-time physical activity, such as non-participation in sports. This study is the first to explore whether absolute and relative educational inequalities in sporting inactivity among adults have changed in Germany since the early 2000s.

METHODS

Data from four cross-sectional national health surveys conducted in 2003 (n = 6890), 2009 (n = 16,418), 2010 (n = 17,145) and 2012 (n = 13,744) were analysed. The study population was aged 25-69 years in each survey. Sporting inactivity was defined as no sports participation during the preceding 3 months. The regression-based Slope Index of Inequality (SII) and Relative Index of Inequality (RII) were calculated to estimate the extent of absolute and relative educational inequalities in sporting inactivity, respectively.

RESULTS

Sporting inactivity was consistently more prevalent in less-educated groups. The overall prevalence of sporting inactivity declined significantly over time. However, the decline was observed only in the high and medium education groups, while no change was observed in the low education group. Both absolute and relative educational inequalities in sporting inactivity were found to have widened significantly between 2003 (SII = 0.30, 95% CI = 0.25-0.35; RII = 2.08, 95% CI = 1.83-2.38) and 2012 (SII = 0.41, 95% CI = 0.37-0.45; RII = 3.44, 95% CI = 3.03-3.91). Interaction analysis showed that these increases in inequalities were larger in the younger population under the age of 50 than among the elderly.

CONCLUSIONS

The findings suggest that the gap in sports participation between adults with high and low educational attainment has widened in both absolute and relative terms because of an increase in sports participation among the better educated. Health-enhancing physical activity interventions specifically targeted to less-educated younger adults are needed to prevent future increases in social inequalities in health.

Health-risk behaviour among residents in deprived neighbourhoods compared with those of the general population in Denmark: A cross-sectional study

This study compares health-risk behaviours (including the co-occurrence of health-risk behaviours) of residents in the deprived neighbourhoods with those of the general population of Denmark. It also examines associations between sociodemographic and socioeconomic characteristics and health-risk behaviours in deprived neighbourhoods in Denmark. Even after adjustment for socioeconomic characteristics there were large differences in health-risk behaviours between residents in deprived neighbourhoods and the general population. In the deprived neighbourhoods large sociodemographic and socioeconomic differences in health-risk behaviours were found among the residents. Our findings highlight the need for health promotion programmes targeting residents in deprived neighbourhoods.

Social Inequalities and Depressive Symptoms in Adults: The Role of Objective and Subjective Socioeconomic Status

BACKGROUND

There is substantial evidence that lower objective socioeconomic status (SES)-as measured by education, occupation, and income-is associated with a higher risk of depression. Less is known, however, about associations between perceptions of social status and the prevalence of depression. This study investigated associations of both objective SES and subjective social status (SSS) with depressive symptoms among adults in Germany.

METHODS

Data were obtained from the 2013 special wave of the German Health Update study, a national health survey of the adult population in Germany. Objective SES was determined using a composite index based on education, occupation, and income. The three single dimensions of the index were also used individually. SSS was measured using the MacArthur Scale, which asks respondents to place themselves on a 10-rung 'social ladder'. Regression models were employed to examine associations of objective SES and SSS with current depressive symptoms, as assessed with the eight-item Patient Health Questionnaire depression scale (PHQ-8 sum score ≥10).

RESULTS

After mutual adjustment, lower objective SES and lower SSS were independently associated with current depressive symptoms. The associations were found in both sexes and persisted after further adjustment for sociodemographic factors, long-term chronic conditions, and functional limitations. Mediation analyses revealed a significant indirect relationship between objective SES and depressive symptoms through SSS. When the three individual dimensions of objective SES were mutually adjusted, occupation and income were independently associated with depressive symptoms. After additional adjustment for SSS, these associations attenuated but remained significant.

CONCLUSIONS

The findings suggest that perceptions of low social status in adults may be involved in the pathogenesis of depression and play a mediating role in the relationship between objective SES and depressive symptoms. Prospective studies are needed to establish the direction of effects and to address questions of causality.

Quality of life following coronary artery bypass graft surgery vs. percutaneous coronary intervention in diabetics with multivessel disease: a five-year registry study

Aims

The aim of this study is to investigate the long-term relationship between revascularization technique and health status in diabetics with multivessel disease.

Methods and results

Using the Alberta Provincial Project for Outcomes Assessment in Coronary Heart Disease (APPROACH) registry, we captured 1319 diabetics with multivessel disease requiring revascularization for an acute coronary syndrome (January 2009–December 2012) and reported health status using the Seattle Angina Questionnaire (SAQ) at baseline, 1, 3 and 5-years [599 underwent coronary artery bypass grafting (CABG); 720 underwent percutaneous coronary intervention (PCI)]. Adjusted analyses were performed using a propensity score-matching technique. After adjustment (including baseline SAQ domain scores), 1-year mean (95% CI) SAQ scores (range 0–100 with higher scores reflecting improved health status) were significantly greater in selected domains for CABG compared to PCI (exertional capacity: 81.7 [79.5–84.0] vs. 78.8 [76.5–81.0], P = 0.07; angina stability: 83.1 [80.4–85.9] vs. 75.0 [72.3–77.8], P &lt; 0.001]; angina frequency 93.2 [91.6–95.0] vs. 90.0 [87.8–91.3], P = 0.003; treatment satisfaction: 93.6 [92.2–94.9] vs. 90.8 [89.2–92.0], P = 0.003; quality of life [QOL]: 83.8 [81.7–85.8] vs. 77.2 [75.2–79.2] P &lt; 0.001). At 3-years, these benefits were attenuated (exertional capacity: 79.3 [76.9–81.7] vs. 78.7 [76.3–81.1], P = 0.734; angina stability 79.3 [76.3–82.3] vs. 75.5 [72.5–78.5], P = 0.080; angina frequency: 93.2 [91.3–95.1] vs. 90.9 [89.0–92.8], P = 0.095; treatment satisfaction: 92.5 [91.0–94.0] vs. 91.5 [90.0–93.0] P = 0.382; QOL: 83.2 [81.1–85.2] vs. 80.3 [78.2–82.4], P = 0.057). At 5-years, majority of domains were similar (exertional capacity: 77.8 [75.0–80.6] vs. 76.3 [73.2–79.3], P = 0.482; angina stability: 78.0 [74.8–81.2] vs. 74.8 [71.4–78.2], P = 0.175; angina frequency: 94.2 [92.3–96.0] vs. 90.9 [89.0–92.9], P = 0.018; treatment satisfaction: 93.7 [92.2–95.1] vs. 92.2 [90.6–93.7], P = 0.167; QOL: 84.1 [82.0–86.3] vs. 81.1 [78.8–83.4], P = 0.058). Majority in both groups remained angina-free at 5-years (75.0% vs. 70.3%, P = 0.15).

Conclusion

Improvements in health status with CABG compared with PCI were not sustained long-term. This temporal sequence should be considered when contemplating a revascularization strategy in diabetics with multivessel disease.

[Socioeconomic differences in physical activity in the middle-aged working population: The role of education, occupation, and income]

BACKGROUND

Regular physical activity has positive effects on health at all ages. This study aims to investigate how far physical activity and regular sports engagement, as a more specific type of physical activity, are associated with socioeconomic factors in the middle-aged working population.

METHODS

Data were obtained from 21,699 working men and women aged between 30 and 64 years who participated in the 2009 and 2010 population-based national German Health Update (GEDA) surveys conducted by the Robert Koch Institute. Besides a multi-dimensional index of socioeconomic status (SES), three single dimensions of SES (education, occupation, and income) were used to analyse socioeconomic differences in total physical activity and regular sports engagement.

RESULTS

While the prevalence of total physical activity increased with lower SES, the proportion of people with regular sports engagement decreased with lower SES. These associations remained after adjusting for age in men and women. After mutual adjustment of the three single socioeconomic dimensions, physical activity was independently associated with lower education and lower occupational status. Regular sports engagement was observed to be independently associated with higher education, higher occupational status, as well as higher income after mutual adjustment.

CONCLUSIONS

This study demonstrates significant socioeconomic differences in physical and sports activity in the middle-aged working population. Education, occupation, and income show varying independent associations with physical activity behaviour. Such differences need to be considered when identifying target groups for health-enhancing physical activity interventions.

Smoking and Passive Smoke Exposure Among Adolescents in Germany

BACKGROUND

Children and adolescents are the most important target group for smoking prevention and non-smoker protection measures (smoke-free legislation). In this article, we discuss trends over time and differences between social groups with regard to smoking and passive smoke exposure among adolescents in Germany.

METHODS

The data evaluated in this article were collected in two different study periods of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS), namely, 2003-2006 and 2009-2012. Adolescents aged 11 to 17 were asked about their smoking behavior and passive smoke exposure (6812 and 5258 respondents in the two study periods, respectively). Their social status was rated with an index based on information supplied by the adolescents' parents about their level of education, occupation, and income.

RESULTS

The prevalence of smoking among adolescents fell in approximately six years from 20.4% to 12.0% (p< 0.001), and that of daily smoking from 13.3% to 5.4% (p<0.001). The percentage of non-smokers who spent time several days per week, or every day, in rooms where other persons were smoking declined from 35.1% to 18.8% (p<0.001). The lower the respondents' social status, the more likely they were to smoke daily and to have regular passive exposure to smoking.

CONCLUSION

The findings suggest that the measures implemented in recent years to protect adolescents from the health risks of active and passive smoking have been beneficial independently of the adolescents' social backgrounds.

[Health literacy of adults in Germany: Findings from the German Health Update (GEDA) study]

BACKGROUND

In today's information society, health literacy (HL) is considered important for health maintenance and disease management. In this context, dealing with health information is fundamental and requires different cognitive and social skills.

OBJECTIVES

The aim of this study was to investigate the distribution of HL levels in the adult population of Germany, and to identify associations with health behaviours and health status.

MATERIALS AND METHODS

The analyses were based on data from the German Health Update (GEDA) study, a cross-sectional survey of the German-speaking adult population of Germany, which was conducted from October 2013 to June 2014. Health literacy was assessed with the short form of the European Health Literacy Questionnaire (HLS EU-Q16), along with questions about socio-demographics, health behaviours, and health status. The HLS-EU-Q16 index could be calculated for 4845 respondents.

RESULTS

According to the criteria of the HLS-EU-Q16, more than half of the adults had "adequate" HL (55.8 %). Every third person (31.9 %) had "problematic" and almost every eighth person (12.3 %) had "inadequate" HL. We found significant differences in HL by educational level, but no differences in HL by sex and age group. Certain health behaviours were positively associated with health literacy. A low HL level was associated with poorer physical and mental health.

CONCLUSION

The results point to a need for action to improve HL in the adult population. The strengthening of health literacy should not solely aim at the promotion of individual skills, but also give high priority to the development of health-literate settings.

Social disparities in parental smoking and young children's exposure to secondhand smoke at home: a time-trend analysis of repeated cross-sectional data from the German KiGGS study between 2003-2006 and 2009-2012

Background

Children who are exposed to secondhand smoke (SHS) have an increased risk of a wide range of health problems and illnesses. Smoke-free legislation aims to improve indoor air quality and in this way protect the health of people who do not smoke. This paper examines trends in SHS exposure at home among children in Germany since the introduction of smoking bans in public places. Special focus is placed on the importance of the family of origin’s socioeconomic status (SES) and on parental smoking behaviour.

Methods

The analyses are based on two waves of the “German Health Interview and Examination Survey for Children and Adolescents” (KiGGS)—one of which was conducted immediately before the introduction of central smoke-free legislation in the 2003-2006 period, the other approximately 6 years later from 2009 to 2012. A comparison is made between the answers given by the parents of children aged between 0 to 6 (KiGGS baseline study, n = 6680; KiGGS Wave 1, n = 4455). Domestic SHS exposure is covered in the parent interviews by asking whether anyone is allowed to smoke at home in the presence of their child. Parental smoking behaviour is determined separately for mothers and fathers. SES is determined on the basis of the parents’ education, occupational status and income.

Results

The percentage of 0- to 6-year-old children exposed to SHS in the parental home fell from 23.9 to 6.6 % in the period from 2003-2006 to 2009-2012. At the same time, the percentage of children with at least one parent who smokes decreased from 49.8 to 41.8 %. While relative social inequalities in parental smoking behaviour have tended to increase over time, inequalities in domestic SHS exposure have persisted. Children whose parents smoke and children from low-SES families are still most likely to be exposed to tobacco smoke. In both study periods and after statistical adjustment for parental smoking behaviour, children with a low SES had a 6.6-fold higher risk for SHS exposure in the parental home than children from high-SES households.

Conclusions

The results of the KiGGS study show that the proportion of children in Germany who are exposed to SHS at home has declined significantly over the last few years. There is much to suggest that the smoke-free legislation that has been introduced in Germany has led to a heightened awareness of the health risks of SHS both in public and in the private sphere, as well as to a denormalization of smoking. Children whose parents smoke, and among them particularly children from socially disadvantaged families, should be recognised as key target groups when implementing future tobacco-control measures.

Social Disparities in Maternal Smoking during Pregnancy: Comparison of Two Birth Cohorts (1996-2002 and 2003-2012) Based on Data from the German KiGGS Study

Background: Maternal smoking during pregnancy represents a significant developmental risk for the unborn child. This study investigated social differences in maternal smoking behavior during pregnancy in mothers living in Germany. The study focused on maternal age at delivery, social status and migration background. Method: The evaluation of data was based on two surveys carried out as part of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) carried out in 2003-2006 and in 2009-2012. The study compared the information given by parents of children aged between 0 and 6 years who were born either in the period from 1996 to  2002 (KiGGS baseline study, n = 4818) or in the period from 2003 to 2012 (KiGGS Wave 1, n = 4434). Determination of social status was based on parental educational levels, occupational position and income. Children classified as having a two-sided migration background either had parents, both of whom had immigrated to Germany, or were born abroad and had one parent who had immigrated to Germany; children classified as having a one-sided migration background had been born in Germany but had one parent who had immigrated to Germany. Results: The percentage of children whose mothers had smoked during pregnancy was 19.9 % for the older birth cohort and 12.1 % for the younger birth cohort. In both birth cohorts, the probability of being exposed to tobacco smoke was twice as high for children whose mothers were aged < 25 years at delivery compared to the children of older mothers. Children from socially deprived families were most affected by smoking behavior, and the relative social differences were found to have even increased over time (KiGGS baseline study: OR = 6.34; 95 % CI = 4.53-8.86; KiGGS Wave 1: OR = 13.88; 95 % CI = 6.85-28.13). A two-sided migration background was associated with a lower risk of exposure to smoking. Conclusions: The KiGGS results are in accordance with the results of other national and international studies which have shown that the percentage of mothers who smoke during pregnancy is declining. Because of a change in the method how data are collected for the KiGGS survey (written questionnaire vs. telephone interview) the trend results must be interpreted with caution. Measures aimed at preventing smoking and weaning women off smoking should focus particularly on younger and socially deprived mothers.

Development of health-related quality of life and symptoms of anxiety and depression among persons diagnosed with cancer during adolescence: a 10-year follow-up study

OBJECTIVE

The main aim was to investigate the development of health-related quality of life (HRQOL) and symptoms of anxiety and depression in a cohort diagnosed with cancer during adolescence from shortly after up to 10 years after diagnosis.

METHODS

Participants (n = 61) completed the SF-36 and the HADS shortly; six, 12, and 18 months; and two, three, four, and 10 years (n = 28) after diagnosis. Polynomial change trajectories were used to model development.

RESULTS

Polynomial change trajectories showed an initial increase which abated over time into a decrease which abated over time for the SF-36 subscales Mental Health and Vitality; an initial decline which abated over time into an increase for HADS anxiety; and an initial decline which abated over time into an increase which abated over time for HADS depression. The SF-36 mental component summary showed no change from two to 10 years after diagnosis whereas the SF-36 physical component summary showed an increase from two years after diagnosis which declined over time. Ten years after diagnosis 29% reported possible anxiety.

CONCLUSIONS

Development of HRQOL and symptoms of anxiety and depression appears to be non-linear among persons diagnosed with cancer during adolescence. Well into permanent survivorship an increase in symptoms of anxiety is shown and approximately a third of the participants report possible anxiety. The findings indicate the need for: studies designed to pinpoint the times of highest psychological risk, clinical follow-up focusing on psychological problems, and development of effective psychological interventions for survivors of adolescent cancer. © 2015 The Authors.
