In one study from the US, higher psychological distress, higher role overload, and lower marital and family satisfaction predicted continued career employment in contrast to full retirement, whereas for work-related factors, a significant association was found for lower career goal achievement only ( 20 ).

If we wish to address complex disease risk across lifespan, we need to study diseases developing in adolescence and young adulthood, such as asthma, autoimmune disease and major psychoses. (nature.com)

This study demonstrates the feasibility of conducting a trial based centrally on mobile MR-measurements which were performed during ten weeks while crossing an entire continent. (biomedcentral.com)
The BIG cohort demonstrates that early implementation of new tuberculosis treatments in the United States is feasible. (cdc.gov)

Effective treatment for OSAS with continuous positive airway pressure (CPAP) is associated with considerable benefits in cardiovascular comorbidity, particularly hypertension, both in short-term randomised controlled studies and in long-term observational studies [ 8 - 12 ]. (ersjournals.com)

This study aimed to validate Italian versions of Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) scale and Pain DETECT questionnaire (PD-Q) and evaluate the ability of these questionnaires to discriminate between nociceptive and neuropathic pain. (hindawi.com)
In particular, several questionnaires have been created and validated in different languages to discriminate between different types of pain, such as the Pain DETECT questionnaire (PD-Q) and the Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) scale [ 3 , 4 ], which can be used in the challenging diagnosis of neuropathic pain (NeP). (hindawi.com)

A substantial literature on QA and QC has appeared in the framework of cohort studies and clinical trials. (hindawi.com)

Cardiovascular diseases represent an important comorbidity and there is evidence that OSAS independently relates to prevalent and incident systemic hypertension in many [ 3 , 4 ], but not all [ 5 , 6 ] population-based studies. (ersjournals.com)
However, the respective contribution of these mechanisms to established hypertension is unclear, and previous population studies of the association of hypertension and OSAS have not addressed this question in detail [ 4 , 20 ]. (ersjournals.com)
The CRS facilitates sampling of general population comparison cohorts, controls in case-control studies, family studies and targeted population surveys. (cdc.gov)
Demographics - Existing US cohorts do not completely represent the American population or projected demographic changes. (cdc.gov)
7. Morgan VA, Leonard H, Bourke J, Jablensky A. Intellectual disability co-occurring with schizophrenia and other psychiatric illness: population-based study. (gla.ac.uk)
This study examines whether it is also independent predictor of incident cancer, coronary heart disease (CHD) and mortality in the general population. (biomedcentral.com)

All cohorts provided respiratory outcome information for their cohort based on their study definitions. (cdc.gov)

The study cohort is limited to a group of black and white girls who were seen annually for ten years. (wikipedia.org)
A study was conducted in the child-bearing women exposed to the toxin, with their baby girls reaching menarche by the age of 11.6 years, compared to girls who had low exposure reaching menarche by the age of 12.2-12.6 years. (wikipedia.org)
The study cohort contributed 8484.8 person years, with an overall survival rate of 3.3 per 100 person years (95% CI 3.0 to 3.7). (bmj.com)

An ecological study exploring the association between releases of certain industrial chemicals, including six chemicals and six metals, found positive associations for select compounds and breast cancer rates, but could not account for personal breast cancer risk factors [ 19 ]. (biomedcentral.com)

Risk of bias was assessed with the Newcastle-Ottawa scale (NOS). (medrxiv.org)
In full cohort studies and in efficient, unbiased designs, the estimate of the hazard ratio for the exposure of interest is based on the weighted differences between the exposure of each case and the weighted average of the exposures in the corresponding risk sets. (aacrjournals.org)
On the other hand, the exposure distribution of controls in the risk sets chosen in designs that lead to bias does not reflect the exposure distribution of the risk set in the full cohort. (aacrjournals.org)
Dental scaling was significantly associated with a lower risk of ESRD (adjusted hazard ratio (aHR): 0.83, 95% confidence interval (CI): 0.77-0.90). (tmu.edu.tw)
In addition, there was a dose-dependent relationship between the frequency of dental scaling and a reduced risk of ESRD. (tmu.edu.tw)
Interestingly, recent studies conducted in Western countries suggest that extreme dietary habits for carbohydrates and fats are associated with a higher risk of mortality. (omniaeducation.com)
However, this study shows that low-carbohydrate and low-fat diets may not be the healthiest strategy for promoting longevity, as their short-term benefits could potentially be outweighed by long-term risk. (omniaeducation.com)
The study-specific risk estimates were pooled using a random-effects model. (frontiersin.org)
Two large cohort studies based on the Danish Cancer Register indicated that benign ovarian tumors may be associated with a long-term increased risk of both mucinous and borderline ovarian cancers ( 7 , 8 ). (frontiersin.org)
A pooled analysis of eight case-control studies with 5207 cases and 7705 controls in multiple countries suggested that ovarian cysts may not be associated with the risk of ovarian cancer ( 9 ). (frontiersin.org)
ASD is genetically heritable, though some recent studies implicate environmental factors in a substantial percentage of ASD risk. (cdc.gov)
Alcohol use during pregnancy merits investigation as a possible ASD risk factor, given studies linking high prenatal alcohol exposure with neurodevelopmental effects, such as decreased intellectual ability, hyperactivity, motor skill impairments, and learning difficulties. (cdc.gov)
Although several past studies have quantified the impact of individual risk factors in Japan, to our knowledge no study has assessed and compared the effects of multiple modifiable risk factors for non-communicable diseases and injuries using a standard framework. (who.int)

This cross sectional study suggests that chronic intermittent hypoxia plays an important role in OSAS-related hypertension. (ersjournals.com)

In two of eight cohorts for women and two of seven cohorts for men, allergic asthma was more common than non-allergic asthma. (cdc.gov)

Ninomiya commented: 'Although this study is a snapshot in time and does not conclude that social isolation causes brain atrophy, several studies have shown that exposing older people to a socially stimulating group stops the decline in brain volume and improves thinking and memory, suggesting that interventions to improve social isolation may prevent the decline in brain volume and associated dementia. (go.jp)

Clinical characteristics, in-hospital complications, and outcome at 3 months post-SAH (Glasgow Outcome Scale score) were analyzed with regard to the presence or absence of IVH. (nih.gov)

Empirical evidence from genome-wide association studies can supplement intuition and simulations in comparing properties of various case-control designs within cohorts. (aacrjournals.org)
However, other studies did not observe a statistically significant association. (frontiersin.org)
We found only one epidemiologic study specifically examining alcohol intake and ASD, which observed no association between alcohol and either ASD or infantile autism. (cdc.gov)
Here we examined the association between maternally-reported alcohol use during the preconception and prenatal periods and ASD in the Study to Explore Early Development (SEED), a large multi-site case-control study. (cdc.gov)
