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.

Associations of Migration, Socioeconomic Position and Social Relations With Depressive Symptoms - Analyses of the German National Cohort Baseline Data.

Objectives: We analyze whether the prevalence of depressive symptoms differs among various migrant and non-migrant populations in Germany and to what extent these differences can be attributed to socioeconomic position (SEP) and social relations. Methods: The German National Cohort health study (NAKO) is a prospective multicenter cohort study (N = 204,878). Migration background (assessed based on citizenship and country of birth of both participant and parents) was used as independent variable, age, sex, Social Network Index, the availability of emotional support, SEP (relative income position and educational status) and employment status were introduced as covariates and depressive symptoms (PHQ-9) as dependent variable in logistic regression models. Results: Increased odds ratios of depressive symptoms were found in all migrant subgroups compared to non-migrants and varied regarding regions of origins. Elevated odds ratios decreased when SEP and social relations were included. Attenuations varied across migrant subgroups. Conclusion: The gap in depressive symptoms can partly be attributed to SEP and social relations, with variations between migrant subgroups. The integration paradox is likely to contribute to the explanation of the results. Future studies need to consider heterogeneity among migrant subgroups whenever possible.

Health and life insurance-related problems in very long-term cancer survivors in Germany: a population-based study.

PURPOSE: Limited research suggests that cancer survivors have problems with insurance. Our study aimed to gain insight into the proportion of very long-term (14-24 years post-diagnosis) survivors of breast, colorectal, and prostate cancers who had problems with health (HI) and life (LI) insurance. METHODS: We used data from CAESAR (CAncEr Survivorship-A multi-Regional population-based study). Participants completed questions on change in insurance providers since cancer diagnosis, problems with requesting (additional) HI or LI, and how potential problems were resolved. We conducted logistic regression to determine factors associated with change in statutory HI. RESULTS: Of the 2714 respondents, 174 (6%) reported having changed HI providers. Most switched between different statutory HI providers (86%), 9% from statutory to private, and 5% from private to statutory. Respondents who changed statutory HI providers were more likely to be prostate cancer survivors (OR 2.79, 95% CI 1.01-7.68) while being ≥ 65 years at time of diagnosis (OR 0.58, 95% CI 0.35-0.96) and having ≥ 2 comorbid conditions (OR 0.61, 95% CI 0.40-0.92) were associated with reduced odds for change. Problems in changing HI were minimal and were resolved with additional contribution. Of the 310 respondents who tried to get LI, 25 respondents reported having difficulties, of whom the majority had their request rejected. CONCLUSION: Most cancer survivors did not change their HI nor tried to buy LI after cancer diagnosis. Problems with changing statutory HI were generally resolved with additional contribution while the main problem encountered when buying LI was rejection of request.

[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.

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.

LA EDAD AL DIAGNÓSTICO Y EL GÉNERO ESTÁN ASOCIADOS CON DÉFICITS A LARGO PLAZO EN LA CALIDAD DE VIDA RELACIONADA CON LA SALUD ESPECíFICA DE LA ENFERMEDAD DE LOS SOBREVIVIENTES DE CÁNCER DE COLON Y RECTO: UN ESTUDIO BASADO EN LA POBLACIÓN:: A pesar del creciente número de individuos jóvenes diagnosticados con cáncer de colon y recto, la investigación sobre la calidad de vida relacionada con la salud específica de la enfermedad a largo plazo de los sobrevivientes de cáncer de colon y recto jóvenes (<50 años) es escasa.Nuestro estudio tuvo como objetivo comparar los déficits funcionales específicos de la enfermedad y los síntomas de los sobrevivientes de cáncer de colon y recto 5-16 años después del diagnóstico, estratificados por edad al momento del diagnóstico y por género.Transversal.Utilizamos datos del estudio Supervivencia de CAncEr basada en la población: Un estudio multirregional en colaboración con cinco bases de datos alemanas de cáncer basados en la población.Sobrevivientes de cáncer de colon y recto.Los encuestados respondieron el módulo de calidad de vida específica para la enfermedad en cáncer colorrectal de la Organización Europea para la Investigación y Tratamiento del Cáncer. Las categorías de edad al diagnóstico fueron <50, 50-59, 60-69 y ≥70 años. Los puntajes de CVRS (calidad de vida relacionada a la salud) medios mínimos cuadrados, derivados de la regresión lineal, se ajustaron por género, educación, tiempo desde el diagnóstico, sitio del cáncer, etapa del cáncer y tratamiento, cuando apropiado.La muestra comprendió 697 y 479 sobrevivientes de cáncer de colon y de recto, respectivamente. En general, los sobrevivientes de cáncer de colon y recto diagnosticados con <50 años de edad reportaron una menor funcionalidad y una mayor carga de síntomas en comparación con los sobrevivientes diagnosticados a una edad más avanzada. Cuando se estratificaron por género, las mujeres sobrevivientes de cáncer de colon tendieron a informar más preocupaciones sobre la pérdida de cabello pero menos problemas sexuales en comparación con los hombres sobrevivientes de colon de la misma edad. Las mujeres sobrevivientes de cáncer rectal en todos los grupos de edad tendieron a informar niveles más bajos de interés sexual que los hombres sobrevivientes de cáncer rectal de la misma edad.Estudio transversal con hallazgos que podrían estar sesgados hacia sobrevivientes a largo plazo más saludables. La generalización de los resultados se limitó a los sobrevivientes diagnosticados antes de 2005.Nuestros resultados sugieren que los cuidados de soporte para los sobrevivientes de cáncer de colon y recto para mejorar su automanejo de síntomas deben adaptarse según el tipo de cáncer, la edad en el momento del diagnóstico y el género.
