Diabetes mellitus in long-term survivors with colorectal, breast, or prostate cancer: Prevalence and prognosis. A population-based study.

BACKGROUND: Patients with cancer are at increased risk of diabetes mellitus (DM). Previous studies on the prevalence and prognostic impact of DM in cancer survivors were limited by small sample sizes or short follow-up times. We aimed to compare the patient-reported prevalence of DM in long-term cancer survivors (LTCS), who survived 5 years or more after cancer diagnosis, with that in cancer-free controls, and to estimate the mortality risk among LTCS according to DM status. METHODS: Our population-based cohort comprised 6952 LTCS diagnosed with breast, colorectal, or prostate cancer between 1994 and 2004, recruited in 2008-2011 (baseline), and followed until 2019. A total of 1828 cancer-free individuals served as controls. Multivariable logistic regression was used to compare the prevalence of DM in LTCS and controls, and according to covariates at baseline. Mortality among LTCS according to DM was assessed by Cox proportional hazards regression. RESULTS: A total of 962 (13.8%) LTCS at baseline reported DM. Prevalence of DM in LTCS was not higher than in cancer-free controls, both at baseline (odds ratio, 0.80; 95% CI, 0.66-0.97) and at follow-up (odds ratio, 0.83; 95% CI, 0.67-1.04). Prevalence of DM in LTCS was associated with cancer site, older age, lower education, higher socioeconomic deprivation, higher body mass index, physical inactivity, other comorbidities, and poorer prognosis (adjusted hazard ratio [all-cause mortality] = 1.29; 95% CI, 1.15-1.44). CONCLUSION: DM in LTCS is prevalent, but not higher than in cancer-free population controls. Cancer survivors with concurrent DM are at a potentially higher risk of death. PLAIN LANGUAGE SUMMARY: Cancer and diabetes mellitus (DM) are two serious threats to global health. In our study, prevalence of DM in long-term cancer survivors who survived 5 years or more after cancer diagnosis was not higher than in cancer-free controls. This should not be interpreted as an indication of a lower risk of DM in cancer survivors. Rather, it highlights the potentially poor prognosis in diabetic cancer survivors. Therefore, keeping a continuous satisfactory DM and hyperglycemia management is essential during long-term cancer survivorship.

Benefit finding, posttraumatic growth and health-related quality of life in long-term cancer survivors: a prospective population-based study.

BACKGROUND: We explored the relationship between benefit finding (BF)/posttraumatic growth (PTG) at baseline and health-related quality of life (HRQOL) at baseline and follow-up in long-term cancer survivors (LTCS; ≥5-year post-diagnosis). MATERIALS AND METHODS: HRQOL was assessed in LTCS in 2009-2011 (5- to 16-year post-diagnosis, baseline) and re-assessed in 2018/2019 (14- to 24-year post-diagnosis, follow-up). BF and PTG were measured at baseline; mean scores were dichotomized into 'none-to-low' (<3) and 'moderate-to-high' (> =3). Linear regression models and linear mixed regression models were employed to assess the association of BF/PTG with HRQOL. RESULTS: Of the 6057 baseline participants, 4373 were alive in 2019, of whom 2704 completed the follow-up questionnaire. Cross-sectionally, LTCS with none-to-low BF reported better HRQOL at baseline and at follow-up than LTCS with higher BF. Longitudinally, no difference was found between none-to-low and moderate-to-high BF on the HRQOL change from baseline to follow-up. HRQOL differences between the PTG groups were not statistically significant cross-sectionally and longitudinally, except those participants with moderate-to-high PTG reported higher role functioning and global health status/QOL. CONCLUSIONS: Cross-sectionally, BF was significantly negatively related to subscales of HRQOL, while PTG was positively correlated to role functioning and global health status/QOL. The results add further evidence that BF and PTG are two different positive psychological concepts.

Distress mediates the relationship between cognitive appraisal of medical care and benefit finding/posttraumatic growth in long-term cancer survivors.

BACKGROUND: The objective of this study was to ascertain long-term cancer survivors' (LTCS') appraisal of medical care and how these perceptions may influence their health and well-being, including benefit finding (BF) and posttraumatic growth (PTG). METHODS: In total, 6952 LTCS from a multiregional population-based study in Germany completed the Benefit Finding Scale, the Posttraumatic Growth Inventory, the Questionnaire on Stress in Cancer, and self-designed questions on cognitive appraisal of medical care. The authors explored the mediating role of distress between medical care appraisal and BF and PTG and the possible moderation of time since diagnosis in this relationship. RESULTS: LTCS' medical care appraisals ("no unresolved/untreated symptoms," "satisfaction with cancer care," and "satisfaction with care for other diseases") were positively associated with BF. PTG was positively associated with "no unresolved/untreated symptoms" and negatively associated with "satisfaction with care for other diseases." Cancer distress partially mediated the associations between appraisals of medical care and BF, between "no unresolved/untreated symptoms" and PTG and between "satisfaction with care for other diseases" and PTG; whereas it totally mediated the association between "satisfaction with cancer care" and PTG. Time was a significant moderator in the model; the negative indirect effect of cognitive appraisal on BF and PTG through cancer distress weakened with longer time since diagnosis. CONCLUSIONS: Cancer survivors' medical care appraisal is associated with their perceptions of BF and PTG through distress. Therefore, distress screening could be part of the regular workup to identify distressed cancer survivors who are not satisfied with medical care; these survivors may benefit from interventions to reduce distress and increase BF and PTG.

Prevalence of benefit finding and posttraumatic growth in long-term cancer survivors: results from a multi-regional population-based survey in Germany.

BACKGROUND: Cancer studies reported mixed results on benefit finding (BF) and posttraumatic growth (PTG) prevalence and few were focused on long-term survivors. METHODS: BF and PTG were assessed in a multi-regional population-based study in Germany with 6952 breast, colorectal and prostate cancer survivors, using the Benefit Finding Scale and Posttraumatic Growth Inventory. We calculated the age-adjusted prevalence, stratified by demographical and clinical characteristics. RESULTS: Overall, 66.0% of cancer survivors indicated moderate-to-high BF, and 20.5% moderate-to-high PTG. Age-adjusted prevalence of BF and PTG differed according to cancer type (breast > colorectal > prostate) and sex (female > male). BF and PTG prevalence were higher in younger than in older respondents; the age-adjusted prevalence was higher in respondents who survived more years after diagnosis. The strength and direction of associations of age-adjusted prevalence with cancer stage, disease recurrence, and time since diagnosis varied according to cancer type and sex. CONCLUSIONS: A substantial proportion of long-term cancer survivors reported moderate-to-high BF and PTG. However, the prevalence was lower in older and male cancer survivors, and during the earlier years after cancer diagnosis. Further longitudinal studies on PTG and BF in cancer survivors are warranted to address heterogeneity in survivors' experience after cancer diagnosis.

Physical activity and long-term fatigue among colorectal cancer survivors - a population-based prospective study.

BACKGROUND: Evidence suggests that physical activity (PA) is beneficial for reducing fatigue in colorectal cancer (CRC) survivors. However, little is known regarding long-term effects of PA on fatigue and whether pre-diagnosis PA is associated with less fatigue in the years after diagnosis. Our study aimed to investigate the association of pre- and post-diagnosis PA with long-term fatigue in CRC survivors. METHODS: This study used a German population-based cohort of 1781 individuals, diagnosed with CRC in 2003-2014, and alive at five-year follow-up (5YFU). Physical activity was assessed at diagnosis and at 5YFU. Fatigue was assessed by the Fatigue Assessment Questionnaire and the EORTC Quality of Life Questionnaire-Core 30 fatigue subscale at 5YFU. Multivariable linear regression was used to explore associations between pre- and post-diagnosis PA and fatigue at 5YFU. RESULTS: No evidence was found that pre-diagnosis PA was associated with less fatigue in long-term CRC survivors. Pre-diagnosis work-related PA and vigorous PA were even associated with higher levels of physical (Beta (ß) = 2.52, 95% confidence interval (CI) = 1.14-3.90; ß = 2.03, CI = 0.65-3.41), cognitive (ß = 0.17, CI = 0.05-0.28; ß = 0.13, CI = 0.01-0.25), and affective fatigue (ß = 0.26, CI = 0.07-0.46; ß = 0.21, CI = 0.02-0.40). In cross-sectional analyses, post-diagnosis PA was strongly associated with lower fatigue on all scales. CONCLUSIONS: In this study, pre-diagnosis PA does not appear to be associated with less fatigue among long-term CRC survivors. Our results support the importance of ongoing PA in long-term CRC survivors. Our findings might be used as a basis for further research on specific PA interventions to improve the long-term outcome of CRC survivors.

Age-specific health-related quality of life in disease-free long-term prostate cancer survivors versus male population controls-results from a population-based study.

BACKGROUND: Prostate cancer (PC) and its treatment may affect PC survivors differently with respect to age. However, little is known regarding age-specific health-related quality of life (HRQoL) in PC survivors 5 years or even ≥ 10 years post-diagnosis. METHODS: The sample included 1975 disease-free PC survivors (5-16 years post-diagnosis) and 661 cancer-free population controls, recruited from two German population-based studies (CAESAR+, LinDe). HRQoL in both populations was assessed using the EORTC QLQ-C30 questionnaire. Additionally, PC survivors completed the PC-specific EORTC QLQ-PR25 questionnaire. Differences in HRQoL between survivors and controls, as well as differences according to age and time since diagnosis were analyzed with multiple regression after adjustment for age, education, stage, and time since diagnosis, where appropriate. RESULTS: In general, PC survivors reported HRQoL and symptom-burden levels comparable to the general population, except for significantly poorer social functioning and higher burden for diarrhea and constipation. In age-specific analyses, PC survivors up to 69 years indicated poorer global health and social functioning than population controls. Stratification by time since diagnosis revealed little difference between the subgroups. On PC-specific symptoms, burden was highest for urinary bother and symptoms, and lowest for bowel symptoms. Younger age was associated with less urinary symptoms but higher urinary bother. CONCLUSION: Long-term disease-free PC survivors reported overall good HRQoL, but experienced persistent specific detriments. Our data suggest that these detriments do not improve substantially with increasing time since diagnosis. Targeted interventions are recommended to prevent PC-related and treatment-related symptoms becoming chronic and to enhance social functioning.

[Persons with migration background in the German National Cohort (NAKO)-sociodemographic characteristics and comparisons with the German autochthonous population]. / Personen mit Migrationshintergrund in der NAKO Gesundheitsstudie ­ soziodemografische Merkmale und Vergleiche mit der autochthonen deutschen Bevölkerung.

BACKGROUND: Persons with a migration background (PmM) as a population group usually differ from the autochthonous population in terms of morbidity, mortality, and use of the health care system, but they participate less frequently in health studies. The PmM group is very heterogeneous, which has hardly been taken into account in studies so far. OBJECTIVES: Sociodemographic characteristics of PmM in the NAKO health study (age, sex, time since migration, education) are presented. In addition, it is examined through an example whether migration background is related to the use of cancer screening for colorectal cancer (hemoccult test). METHODS: Data of the first 101,816 persons of the NAKO were analyzed descriptively and cartographically. The migration background was assigned on the basis of the definition of the Federal Statistical Office, based on nationality, country of birth, year of entry, and country of birth of the parents. RESULTS: Overall, the PmM proportion is 16.0%. The distribution across the 18 study centers varies considerably between 6% (Neubrandenburg) and 33% (Düsseldorf). With 153 countries of origin, most countries are represented in the NAKO. All variables show clear differences between the different regions of origin. In the hemoccult test, persons of Turkish origin (OR = 0.67) and resettlers (OR = 0.60) have a lower participation rate. PmM born in Germany do not differ in this respect from the autochthonous population (OR = 0.99). CONCLUSION: PmM in the NAKO are a very heterogeneous group. However, due to the sample size, individual subgroups of migrants can be studied separately with respect to region of origin.

Health-related quality of life in long-term disease-free breast cancer survivors versus female population controls in Germany.

PURPOSE: Little is known about breast cancer (BC) survivors' health-related quality of life (HRQoL) > 5 or even > 10 years past diagnosis. It is of interest whether, in the long run, survivors' HRQoL aligns with that of the general population. Study objectives were to (1) compare disease-free BC survivors' HRQoL to that of non-cancer controls, and (2) compare long-term survivors (LTS, 5-9 years post-diagnosis), very long-term survivors (VLTS, ≥ 10 years post-diagnosis), and controls with respect to their HRQoL. METHODS: The samples of 2647 disease-free BC survivors (5-16 years post-diagnosis) and 1005 population controls were recruited in German multi-regional population-based studies. HRQoL was assessed by the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30). Differences in HRQoL were assessed with multiple regression, controlling for age and education. RESULTS: Disease-free BC survivors < 80 years (at survey) reported overall global health status/quality of life comparable to controls, but statistically significant lower physical, role, emotional, social, and cognitive functioning. They also indicated more fatigue, insomnia, dyspnoea, and financial difficulties. However, differences were only of trivial or small clinical relevance. At age 80-89, no differences between BC survivors and controls were observed. Deficits in emotional and cognitive functioning and some symptoms (e.g. insomnia and fatigue) persist, as both LTS and VLTS reported more detriments than controls. CONCLUSIONS: In view of the persistent, small but significant detriments in disease-free BC survivors' cognitive and emotional functioning and higher symptom burden, possibilities to prevent detriments from becoming chronic should be explored.

Age at Diagnosis and Sex Are Associated With Long-term Deficits in Disease-Specific Health-Related Quality of Life of Survivors of Colon and Rectal Cancer: A Population-Based Study.

BACKGROUND: Despite the increasing number of younger individuals diagnosed with colon and rectal cancer, research on the long-term disease-specific health-related quality of life of younger (<50 years) survivors of colon and rectal cancer is scarce. OBJECTIVE: Our study aimed to compare disease-specific functional deficits and symptoms of survivors of colon and rectal cancer 5 to 16 years postdiagnosis, stratified by age at diagnosis and by sex. DESIGN: This is a cross-sectional study. SETTING: We used data from the population-based CAncEr Survivorship-A multi-Regional study in collaboration with 5 population-based German cancer registries. PATIENTS: Survivors of colon and rectal cancer were included in the study. MAIN OUTCOME MEASURES: Respondents completed the disease-specific European Organization for Research and Treatment of Cancer Quality of Life colorectal cancer module. Age at diagnosis categories were <50, 50 to 59, 60 to 69, and ≥70 years. Least square mean health-related quality of life scores, derived from linear regression, were adjusted for sex, education, time since diagnosis, cancer site, cancer stage, and treatment, where appropriate. RESULTS: The sample comprised 697 survivors of colon cancer and 479 survivors of rectal cancer. In general, survivors of colon and rectal cancer diagnosed at <50 years of age reported lower functioning and higher symptom burden in comparison with survivors diagnosed at an older age. When stratified by sex, female survivors of colon cancer tended to report more concerns with hair loss but fewer sexual problems when compared with male survivors of colon cancer of the same age. Female survivors of rectal cancer in all age groups tended to report lower levels of sexual interest than male survivors of rectal cancer of the same age. LIMITATIONS: This was a cross-sectional study with findings that could be biased toward healthier long-term survivors. The generalizability of results is limited to survivors diagnosed before 2005. CONCLUSIONS: Our results suggest that supportive care for survivors of colon and rectal cancer to improve their self-management of symptoms should be adapted according to cancer type, age at diagnosis, and sex.

Age-specific health-related quality of life in long-term and very long-term colorectal cancer survivors versus population controls - a population-based study.

Background: Previous research suggests an age differential in health-related quality of life (HRQOL) among long-term (5-10 years post-diagnosis, LTS) colorectal cancer (CRC) survivors. Few studies have specifically addressed the association of age differentials with HRQOL for very long-term CRC survivors (>10 years post-diagnosis, VLTS) and non-cancer population controls. We aimed to assess possible deficits in HRQOL of disease-free CRC-LTS and CRC-VLTS in comparison with non-cancer population controls, and whether the observed pattern varies by age and time since diagnosis. Methods: We used data from the CAncEr Survivorship - A multi-Regional (CAESAR+) study in collaboration with five population-based German cancer registries. HRQOL from controls was accessed from the Lebensqualität in DEeutschland (LinDE) study. All respondents completed the European Organization for Research and Treatment of Cancer Quality of Life Core-30 questionnaire. We calculated least square means of HRQOL scores. Analyses were adjusted for age, sex, and education, where appropriate. Results: The sample included 862 CRC-LTS, 400 CRC-VLTS and 1689 controls. CRC survivors reported overall good HRQOL but significantly poorer social functioning and more problems with dyspnea, constipation, diarrhea and finances than controls. When stratified by age, deficits in functioning and global health, and more problems with symptoms and finances were noted mainly among younger CRC survivors. Further stratification by time since diagnosis showed that similar deficits in HRQOL and symptoms were noted mainly among the younger CRC-LTS group when compared with controls. Generally, CRC-VLTS reported comparable HRQOL to controls. An exception was noted for diarrhea, whereby CRC survivors, regardless of age and time since diagnosis, reported significantly more problems with this symptom than controls. Conclusions: In comparison with non-cancer controls, disease-free CRC survivors reported overall good HRQOL but experience persistent specific detriments in HRQOL many years after diagnosis. In age stratified analyses, HRQOL deficits were noted mainly among younger CRC-LTS.

Return to work after cancer. A multi-regional population-based study from Germany.

Background: With improving prognosis, the ability to return to work after cancer has become a realistic goal but only little is known regarding details such as sustainability, financial consequences, and potential determinants of return to work in long-term survivors in Germany. Methods: We studied return to work in a population-based sample of 1558 long-term cancer survivors, diagnosed in 1994-2004 with breast, colorectal or prostate cancer before age 60 (mean 50.1). Information regarding employment status and financial difficulties was obtained via mailed questionnaires from patients who were identified by six population-based cancer registries in Germany. Cumulative incidence of return to work was determined by time-to-event analysis with consideration of competing events. Chi2 tests and multiple logistic regression modeling were employed to identify potential sociodemographic and clinical determinants of return to work. Results: Within a mean period since diagnosis of 8.3 years, 63% of all working-age cancer survivors initially returned to their old job and another 7% took up a new job. Seventeen percent were granted a disability pension, 6% were early retired (not cancer-related), 4% became unemployed, and 1% left the job market for other reasons. Resumption of work occurred within the first 2 years after diagnosis in 90% of all returnees. Cancer-related reduction of working hours was reported by 17% among all returnees and 6% quit their job due to cancer within 5 years past return to work. The probability of return to work was strongly related with age at diagnosis, tumor stage, education, and occupational class but did not differ with respect to the tumor site, gender nor marital status. Conclusions: Most long-term survivors after breast, colorectal, or prostate cancer of working-age are able to return to work. However, financial problems might arise due to a reduction in working hours. An additional provision of targeted interventions for high-risk groups should be discussed.

The role of psychosocial resources for long-term breast, colorectal, and prostate cancer survivors: prevalence and associations with health-related quality of life.

PURPOSE: Many long-term cancer survivors still have to adjust to possible adverse consequences of the illness or treatment. Resources can play an important role in this adjustment process, but research on this topic is limited, especially for very long-term survivors. This study explores, which resources are most frequently indicated by different subgroups of cancer survivors, and what role resources play for functioning and health-related quality of life (HRQL) in cancer survivors with and without recurrence. METHODS: The sample of 6030 breast, colorectal, and prostate cancer survivors (5-16 years post-diagnosis) was recruited in a German multi-regional population-based study. Personal resources were assessed by a 27-item checklist; HRQL was assessed by the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30). General linear models were used to analyze associations of resources with HRQL. RESULTS: Participants indicated on average 11.4 (SD 5.1) resources as helpful. Family, activities with others, and partnership were indicated most commonly overall, but frequencies varied according to age, sex, and tumor site. Physical activity, health, professional help, calmness, hope, optimism, and hobbies were most important in explaining HRQL variance. Cancer survivors with recurrence and many resources were found to report similar HRQL as survivors without recurrence and only few resources. CONCLUSIONS: The study underlines the importance and situational variability of personal and social resources for cancer survivors' HRQL, even years post-diagnosis. Not only the availability, but also the individual perception and significance of resources should be considered in follow-up cancer care.

Health-related quality of life in long-term survivors with localised prostate cancer by therapy-Results from a population-based study.

OBJECTIVE: Several therapies for localised prostate cancer (PC) are available; all yield similar survival rates. However, each therapy has significant side effects that can influence patients' health-related quality of life (HRQoL) in the long run. METHODS: The study sample included 911 survivors with localised PC, 5-15 years post-diagnosis who were identified from the population-based CAESAR + study in Germany. HRQoL was assessed using the EORTC QLQ-C30 and EORTC QLQ-PR25 questionnaires. The association between type of therapy and HRQoL was assessed with multivariable linear regression and global F-test adjusting for age, time since diagnosis and comorbidities. RESULTS: Overall, survivors treated with radical prostatectomy (RP) or radiotherapy (RT) alone reported the best HRQoL and the lowest symptom burden. Conversely, survivors treated with androgen deprivation therapy (ADT) (& RP/RT) or RP & RT (in combination) reported the worst HRQoL and the highest symptom burden. Significant differences among treatment groups in HRQoL were found for global health status (p = 0.041), social functioning (p = 0.007), urinary symptoms (p = 0.035), bowel symptoms (p = 0.017) and hormonal treatment-related symptoms (p < 0.001) among other symptoms. CONCLUSIONS: Long-term localised PC survivors formerly treated with a combination of RP and RT or with ADT report poorer HRQoL and more symptoms than patients treated with either RP or RT alone.

Quality of life and physical activity in long-term (≥5 years post-diagnosis) colorectal cancer survivors - systematic review.

BACKGROUND: Due to the increasing number of long-term (≥5 years post diagnosis) colorectal cancer survivors, long-term quality of life of these patients is highly relevant. Several studies have reported a positive association between physical activity and quality of life in colorectal cancer survivors, however, so far no systematic review has been published which focuses on long-term colorectal cancer survivors. MATERIAL AND METHODS: A systematic review was conducted using the databases PubMed, Web of Science, PsychINFO, and CINAHL. Studies which investigated associations between physical activity and quality of life in long-term colorectal cancer survivors were included. RESULTS AND CONCLUSION: Ten articles based on seven studies were identified. Long-term colorectal cancer survivors who were physically active reported better quality of life than long-term survivors who were not physically active. Both, moderate to vigorous physical activity and lower levels like light physical activity were associated with higher quality of life. Most studies assessed the association between physical activity and quality of life cross-sectionally but one prospective study which measured physical activity and quality of life at three different points in time also found associations between physical activity and quality of life. The association between physical activity and quality of life seemed to be stronger among women than among men. The findings of this systematic review support an association between physical activity and quality of life in long-term colorectal cancer survivors. However, the evidence is limited as most studies were based on cross-sectional and observational design.

Quality of life in long-term and very long-term cancer survivors versus population controls in Germany.

BACKGROUND: With the increasing number and diversity of cancer survivors, studies of survivors' physical, emotional, and social health are of growing importance. While there is a growing body of literature on the quality of life (QoL) of cancer patients during the early years past diagnosis, less is known regarding QoL in long-term survivors (LTS) (5 + years past diagnosis) and particularly in very long-term survivors (VLTS) (10 + years past diagnosis). The objective of our study is to: (1) compare QoL of long-term cancer survivors and population norms; and (2) assess whether any deficits in QoL of survivors observed 5-10 years past diagnosis persist beyond the 10th year past diagnosis. METHODS: In total 6952 long-term cancer survivors (5-16 years past diagnosis of breast, colorectal, or prostate cancer) from Germany recruited in the context of the population-based CAESAR + study were compared with 1878 population-based controls without a history of cancer. QoL was assessed with the EORTC QLQ-C30. Differences in QoL between survivors and controls were assessed via multiple regression while controlling for age, gender, education, and case mix for survivors 5-9 years and 10 + years past diagnosis separately. RESULTS: Overall QoL in long-term cancer survivors was comparable to population norms but specific deficits in social, role, emotional, cognitive, and physical functioning and symptoms such as insomnia, fatigue, dyspnea, constipation, diarrhea, and financial difficulties were more prevalent in LTSs. Detriments in QoL persisted during the observation period and affected particularly cancer survivors at younger ages (<50 years). Non-significant aggravations in QoL with longer time since diagnosis were observed in very young and very old cancer survivors. CONCLUSIONS: Detriments in health-related quality of life persist over more than a decade and affect predominantly younger patients. Improvements both in early and long-term follow-up care of cancer survivors seem warranted.

Differences in Anthropometric Measures Based on Sex, Age, and Health Status.

BACKGROUND: Obesity is a worldwide health problem. We conducted detailed analyses of anthropometric measures in a comprehensive, population-based, current cohort in Germany. METHODS: In the German National Cohort (NAKO), we analyzed cross-sectional data on body mass index (BMI), waist and hip circumference, subcutaneous (SAT) and visceral adipose tissue (VAT) as measured by ultrasound, and body fat percentage. The data were stratified by sex, age, and self-reported physicians' diagnoses of cardiovascular diseases (CVD), metabolic diseases (MetD), cardiometabolic diseases (CMD), and cancer. RESULTS: Data were available from 204 751 participants (age, 49.9 ± 12.8 years; 50.5% women). Body size measures generally increased with age. Men had a higher BMI, larger waist circumference, and more VAT than women, while women had a larger hip circumference, more SAT, and a higher body fat percentage than men. For example, the mean BMI of participants over age 60 was 28.3 kg/m2 in men and 27.6 kg/m2 in women. CVD, MetD, and CMD were associated with higher anthropometric values, while cancer was not. For example, the mean BMI was 25.3 kg/m2 in healthy women, 29.4 kg/m2 in women with CMD, and 25.4 kg/m2 in women with cancer. CONCLUSION: Obesity is widespread in Germany, with notable differences between the sexes in anthro - pometric values. Obesity was more common in older participants and those with chronic diseases other than cancer. Elevated values were especially common in multimorbid individuals.

Health Service Use Among Migrants in the German National Cohort-The Role of Birth Region and Language Skills.

Objective: To compare health service use (HSU) between migrants and non-migrants in Germany. Methods: Using data from the population-based German National Cohort (NAKO), we compared the HSU of general practitioners, medical specialists, and psychologists/psychiatrists between six migrant groups of different origins with the utilization of non-migrants. A latent profile analysis (LPA) with a subsequent multinomial regression analysis was conducted to characterize the HSU of different groups. Additionally, separate regression models were calculated. Both analyses aimed to estimate the direct effect of migration background on HSU. Results: In the LPA, the migrant groups showed no relevant differences compared to non-migrants regarding HSU. In separate analyses, general practitioners and medical specialists were used comparably to slightly more often by first-generation migrants from Eastern Europe, Turkey, and resettlers. In contrast, the use of psychologists/psychiatrists was substantially lower among those groups. Second-generation migrants and migrants from Western countries showed no differences in their HSU compared to non-migrants. Conclusion: We observed a low mental HSU among specific migrant groups in Germany. This indicates the existence of barriers among those groups that need to be addressed.

Large-scale assessment of physical activity in a population using high-resolution hip-worn accelerometry: the German National Cohort (NAKO).

Large population-based cohort studies utilizing device-based measures of physical activity are crucial to close important research gaps regarding the potential protective effects of physical activity on chronic diseases. The present study details the quality control processes and the derivation of physical activity metrics from 100 Hz accelerometer data collected in the German National Cohort (NAKO). During the 2014 to 2019 baseline assessment, a subsample of NAKO participants wore a triaxial ActiGraph accelerometer on their right hip for seven consecutive days. Auto-calibration, signal feature calculations including Euclidean Norm Minus One (ENMO) and Mean Amplitude Deviation (MAD), identification of non-wear time, and imputation, were conducted using the R package GGIR version 2.10-3. A total of 73,334 participants contributed data for accelerometry analysis, of whom 63,236 provided valid data. The average ENMO was 11.7 ± 3.7 mg (milli gravitational acceleration) and the average MAD was 19.9 ± 6.1 mg. Notably, acceleration summary metrics were higher in men than women and diminished with increasing age. Work generated in the present study will facilitate harmonized analysis, reproducibility, and utilization of NAKO accelerometry data. The NAKO accelerometry dataset represents a valuable asset for physical activity research and will be accessible through a specified application process.

Persisting Deficits in Health-Related Quality of Life of Colorectal Cancer Survivors 14-24 Years Post-Diagnosis: A Population-Based Study.

(1) Background: The health-related quality of life (HRQOL) of colorectal cancer (CRC) survivors >10 years post-diagnosis is understudied. We aimed to compare the HRQOL of CRC survivors 14-24 years post-diagnosis to that of age- and sex-matched non-cancer controls, stratified by demographic and clinical factors. (2) Methods: We used data from 506 long-term CRC survivors and 1489 controls recruited from German population-based multi-regional studies. HRQOL was assessed with the European Organization for Research and Treatment of Cancer Quality of Life Core-30 (EORTC QLQ-C30) questionnaire. We estimated differences in the HRQOL of CRC survivors and controls with multiple regression, adjusted for age at survey, sex, and education, where appropriate. (3) Results: CRC survivors reported poorer social functioning but better health status/QOL than controls. CRC survivors, in general, had higher levels of symptom burden, and in particular diarrhea and constipation, regardless of demographic or clinical factors. In stratified analyses, HRQOL differed by age, sex, cancer type, and having a permanent stoma. (4) Conclusions: Although CRC survivors may have a comparable health status/QOL to controls 14-24 years after diagnosis, they still live with persistent bowel dysfunction that can negatively impact aspects of functioning. Healthcare providers should provide timely and adapted follow-up care to ameliorate potential long-term suffering.

The mediating role of personality traits in the association between childhood trauma and depressive symptoms in young adulthood.

BACKGROUND: The aim of this study was to investigate the mediating role of the Big 5 personality traits (extraversion, neuroticism, openness, agreeableness, conscientiousness) in the association between early traumatization and depressive symptoms in early adulthood (20-25-year-olds) in a German population-based sample. METHODS: A total of 3176 participants from the German National Cohort (NAKO) baseline with an age between 20 and 25 years were included in this investigation. The sum score of the 9-item-version of the Patient Health Questionnaire was used for assessment of depressive symptoms. A structural equation model was built to test the paths between childhood trauma, Big 5 personality traits and depressive symptoms. RESULTS: Overall, 10.7 % of the young adult sample had a PHQ-9 sum score of ten or higher. The final mediation model fitted well for young adults. We found evidence for a partial mediating effect of Big 5 personality traits. LIMITATIONS: We only adjusted for age, sex, and year of data collection and did not include biological factors in the model. CONCLUSION: Young adults with early trauma experiences have a risk for developing depressive symptoms in young adulthood. Personality traits, especially neuroticism, partially mediated the association between early trauma and depressive symptoms for young adults and should be recognized in preventive strategies.
